Company: Shandong Meihuan Rubber & Plastic Co., Ltd.

Product Description: Meihuan Customized Conveyor Belt Cleaning Box – Belt Cleaning EquipmentFriendly reminder: Image and price descriptions are for reference only. For details, please contact us. Thank you.The cleaning box is installed at the head of the conveyor belt and mainly consists of the box body, cleaner, pressure roller, spray device, drying device, cleaning device, discharge device, and liquid supply device. When the return belt passes through the cleaning box, the cleaning device sprays mist onto the working surface of the return belt. A specialized independent shock-absorbing dual-blade cleaner scrapes off the coal dust mixed with the mist, and then a polyurethane cleaner removes the remaining water. The scraped coal dust and water are discharged through a specially designed chute into the auxiliary chute at the head of the existing conveyor belt, entering the downstream belt. To ensure cleaning effectiveness, two sets of pressure rollers are installed at the top of the cleaning box, along with an air configuration to prevent excessive accumulation of scraped coal dust, which could cause material blockage. Additionally, to meet winter usage requirements, the liquid used in the cleaning box can be either water or antifreeze.The implementation of the Meihuan cleaning box has shown significant cleaning results, markedly reducing coal accumulation at the conveyor belt head and lowering belt cleaning costs.Introduction to the Conveyor Belt Cleaning Water TankThe cleaning box (i.e., the conveyor belt washing device) is designed to remove materials adhering to the working surface of the conveyor belt, preventing material buildup on the lower rollers that could cause belt misalignment, spillage, dust generation, and hard-to-remove ground accumulations, thereby polluting the working environment.Working PrincipleThe cleaning box consists of three parts: the spray system, cleaning system, and drying system. When the return belt enters the cleaning box, the idler and pressure rollers work together to ensure the cleaner scrapes material without shaking or damaging the belt. First, high-pressure water mist softens the caked material on the belt surface. The initial stage uses a softened tungsten steel cleaner to remove coarse material, the second stage employs a water-removing cleaner to scrape off moisture, and the third stage uses a fine material cleaner to remove residual fine powder. Finally, the belt is dried with room-temperature high-pressure air before exiting the box.Product Features1. Water lubrication significantly reduces friction and temperature between the blades and the belt, effectively extending the belt's service life.2. The cleaning box is equipped with well-performing observation doors for easy inspection and maintenance.3. A remote electrical control box is installed beside the unit, automatically interconnecting with the main machine. The cleaning system operates synchronously with the belt.4. The cleaning box consumes approximately S tons of water per day. Water flows through a funnel into a small storage tank beside the machine and is continuously recirculated to the spray system via a frequency-conversion booster pump, saving significant manpower and resources while achieving the environmental goal of wastewater recycling and reuse.5. Hopper spray system: Washes the discharge hopper to prevent scraped material from clogging the hopper. more>

Thank you.Product Overview of Belt Cleaning BoxThe belt cleaning box integrates multiple functions such as a spraying system, material cleaning system, belt drying, material recovery, and remote control into one cleaning device. It thoroughly solves the environmental pollution caused by material carryback on the return belt and the issue of belt misalignment caused by residual material adhering to idlers, thereby improving the on-site environment.I. Functions of the Cleaning Box:1: Belt Stabilization System: The cleaning box features a unique belt stabilization system that ensures the belt enters and exits the device smoothly.2: Spraying System: The cleaning box first softens and cleans the adhered material on the conveyor belt, making it easier to proceed to the next step.3:Cleaning System: After the material is softened by the spraying system, it enters a specially designed combination cleaner to remove stubborn material first, followed by fine material, thereby effectively clearing adhered substances. The cleaning, material removal, and water removal blades feature automatic compensation and self-advancing performance.4: Drying System: Since the cleaning box operates with water, residual moisture may remain on the belt. The drying system of our cleaning box effectively removes residual moisture, achieving a belt cleanliness of over 85%.5;Drainage System: The cleaning box's unique drainage system allows the cleaned material to be discharged smoothly from the device to a designated location without causing ground pollution.6;Control System: The control box enables fully automated operation of the device and ensures synchronization with the on-site conveyor belt.II. Components of the Cleaning Box:Cleaning box body, solenoid valve, filter, pressure pump, control box, connecting flanges (installation flange, drainage flange), and wiring.Note: The original water-removal cleaner material was ordinary polyurethane, with a service life of about 2 months, after which it lost its effectiveness. The current device uses carbide material for the water-removal cleaner, which has a longer service life, a 12-month warranty, and does not damage the belt. more>

Product Description: Shanghai Box Substation Recycling, Pudong Prefabricated Substation Recycling Contact, Professional Box Substation Recycling Price in PudongA box substation is a compact complete set of power distribution equipment that combines high-voltage switchgear, distribution transformers, low-voltage switchgear, electric energy metering equipment, and reactive power compensation devices according to a certain wiring scheme within one or several boxes.It integrates functions such as high-voltage power reception, transformer voltage reduction, and low-voltage power distribution, all installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box.It is suitable for use in three-phase AC systems with a rated voltage of 10/0.4KV, serving for line and power distribution purposes.A box substation is a compact complete set of power distribution equipment that combines high-voltage switchgear, distribution transformers, low-voltage switchgear, electric energy metering equipment, and reactive power compensation devices according to a certain wiring scheme within one or several boxes. It integrates functions such as high-voltage power reception, transformer voltage reduction, and low-voltage power distribution, all installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. It is suitable for use in three-phase AC systems with a rated voltage of 10/0.4KV, serving for line and power distribution purposes.Main features of box substations: They occupy a small area. Generally, a box substation occupies only 5~6㎡, and can even be reduced to 3~3.5㎡. They are suitable for places with dense loads such as industrial and mining enterprises, ports, and residential communities, allowing high-voltage power supply to extend to load centers, reducing low-voltage power supply radius, and minimizing losses. The number of low-voltage power supply lines is relatively small, typically 4~6 lines. They shorten on-site construction cycles and require less investment. Their novel and aesthetically pleasing appearance can harmonize with the surrounding environment of the substation.Typically, the main component is a three-phase oil-immersed power transformer, with high and low-voltage switches, electric energy metering, lightning protection, and other components reasonably arranged and compactly connected, all placed within a steel structure box room, integrated into one. It possesses both power transformation and distribution functions, along with metering devices, making it a complete, compact, space-saving, and easily installable power reception and distribution substation.Box substations are mainly composed of multiple high-voltage switch systems, armored busbars, substation integrated automation systems, communication, remote control, metering, capacitor compensation, DC power supply, and other electrical units combined and installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. They feature electromechanical integration and fully enclosed operation, with the following key characteristics:Fully intelligent station design: The protection system uses substation microcomputer integrated automation devices, installed in a decentralized manner, enabling "four remotes" – telemetry, teleindication, telecommand, and teleregulation. Each unit has independent operation functions, comprehensive relay protection, remote setting of operating parameters, control of humidity and temperature inside the box, and remote smoke alarm, meeting the requirements for unattended operation. Additionally, remote image monitoring can be implemented as needed.Factory prefabrication: During design, as long as the designers create the primary wiring diagram and design for external equipment based on the actual requirements of the substation, they can select the specifications and models of box substations provided by manufacturers. All equipment is installed and debugged once in the factory, truly realizing factory-based substation construction and shortening the design and manufacturing cycle. On-site installation only requires box positioning, cable connections between boxes, outgoing cable connections, protection setting verification, transmission tests, and other debugging work. The entire substation, from installation to operation, takes about 5 to 8 days, significantly reducing construction time.Due to their compact structure, each box forms an independent system, allowing for flexible and diverse combinations. On one hand, we can adopt an all-box approach, meaning that both 35kV and 10kV equipment are installed inside the box, forming a fully box-type substation. Alternatively, only the 10kV switchgear can be boxed, with 35kV equipment installed outdoors and 10kV equipment and control protection systems installed inside the box. This combination is particularly suitable for the renovation of old stations in rural grid upgrades, where the existing 35kV equipment remains unchanged, and only a 10kV switchgear box needs to be installed to meet the requirements for unattended operation. In summary, box substations do not have fixed combination modes, and users can freely combine various modes based on actual conditions to meet the needs of safe operation. more>
