Product Description: Cleaning Conveyor Belt Device MH-1200 Belt Width Spray Cleaning BoxInstructions for Use of Conveyor Belt Cleaning Box EquipmentThe conveyor belt cleaning box is a device used to remove adhered materials from the conveyor belt. It not only effectively cleans the belt but also dries it, reducing the impact of chemical reactions on the belt, thereby extending its service life.Below are the instructions for using the conveyor belt cleaning box, compiled based on search results:Cleaning Box Function Introduction1. Belt Stabilization SystemThe cleaning box features a unique belt stabilization system that ensures the belt enters and exits the device smoothly.2. Spray SystemThe cleaning box first softens and cleans the adhered materials on the conveyor belt, making it easier for the materials to proceed to the next process.3. Cleaning SystemAfter the materials are softened by the spray system, they enter a specially designed combination cleaner to remove stubborn materials first, followed by fine particles, maximizing the removal of adhered materials.4. Drying SystemSince the cleaning box operates with water, residual moisture may remain on the belt. The unique drying system of our cleaning box effectively removes this residual moisture, achieving a cleanliness level of over 85%.5. Drainage SystemThe cleaning box's unique drainage system allows the removed materials to be smoothly discharged from the device to the designated location without causing ground pollution.6. Control SystemThe control box enables fully automated operation of the device and synchronizes with the on-site conveyor belt system.Components of the Cleaning BoxCleaning box body, solenoid valve, filter, pressure pump, control box, connecting flanges (installation flange, drainage flange), and wiring.Usage Steps1. PreparationEnsure all components are intact, check if the control box is functioning properly, and connect the power and water sources.2. Starting the DeviceTurn on the power switch, and the device will automatically enter standby mode.3. Cleaning the BeltWhen the conveyor belt starts operating, the cleaning device interlinks with the belt system and immediately begins working. First, the return belt above the cleaning machine is slowly pressed down by the automatic engagement/disengagement device, ensuring full contact between the belt surface and the water-spray softening roller and cleaning system blades. Next, the solenoid valve opens, and purified water is evenly sprayed onto the belt surface through nozzles, washing and softening the adhered materials. These materials are then gradually removed by the cleaning system blades to achieve a clean belt surface. The removed sludge and excess water are temporarily collected in the collection box below the device and then discharged at a fixed point by the spiral drainage system. When the conveyor belt stops, the cleaning system ends its operation, and the automatic engagement/disengagement device withdraws, returning the belt to its initial state.4. Drying the BeltThe cleaning box's unique drying system effectively removes residual moisture from the belt, achieving a cleanliness level of over 85%.5. Maintaining the DeviceRegularly inspect and replace worn parts to maintain the device's optimal operating condition.Precautions·During use, pay attention to the maintenance and upkeep of the device. Clean impurities from the filter and nozzles promptly to ensure smooth water flow.·If the device malfunctions, stop using it immediately and have it inspected and repaired by professionals.The above are the basic instructions for using the conveyor belt cleaning box. Please note that specific operational details may vary depending on the device model and usage environment. It is recommended to read the device manual carefully before use and adhere to relevant safety operating procedures. Shandong Meihuan more>

Product Description: Hot Water Boiler Computer Control Box The RS-8 fully automatic boiler controller uses a microcontroller from Fujitsu of Japan as its core processor, offering extremely high reliability and strong electromagnetic interference resistance. This controller features 17 functions and is suitable for various small boilers (for boiling water or heating water). It has a simple structure, easy operation, stable and reliable performance, and offers excellent cost-effectiveness. It can be installed on boilers of various shapes and specifications (vertical, horizontal, cylindrical, square).   Electrical Performance                                                                  Operation Mode: Fully automatic continuous operation; runs according to preset parameters. Timed Operation Mode: Operates according to preset parameters within four time periods. Manual Control Operation Mode: Manually controls the burner and water pump start/stop (for testing and debugging). Basic Functions: 4-digit display and indicator lights show control status, water pump status, operation status, current water level, and water temperature. 2 touch operation buttons;       24-hour clock circuit, with battery backup for over 3 days after power failure;       Power-off memory function; automatically resumes operation in the pre-power-off mode after power restoration, suitable for unattended operation. Signal Input: 1 temperature input for measuring boiler water temperature, range 00°C–110°C. 3 water level signal inputs (water electrode conduction resistance less than 20K, cutoff resistance greater than 200K). 1 other fault signal switch input (external faults such as excessively high water level, excessively high pressure, excessively high flue gas temperature, shutdown protection signal input) for various fault protections.           1 burner fault signal (outputs ~AC220V when burner fault or flameout occurs). Control Output: 2 relay normally open contact outputs, rated load power below 1.0KW (250V max 8A). Can drive one single-stage burner and one single-phase (220V, 1KW) water pump. If a three-phase water pump is used, a three-phase high-power control device must be added. Protection Function: In case of faults such as temperature sensor failure, water shortage, water level sensor failure, or other alarms, the burner and water pump are automatically shut off with audible and visual alarms. Press any key to cancel the alarm and return to shutdown status. After the fault is resolved, press the "Start/Stop" key to resume operation. In case of a burner fault, the water pump is immediately shut off with audible and visual alarms, while the burner continues to output control for 30 seconds before stopping, allowing time for the operator to reset the burner. During this process, pressing the "Start/Stop" key at any time cancels the alarm and returns to shutdown status. After the fault is resolved, press the "Start/Stop" key again to resume operation. Temperature sensor extension cable: 100 meters. Temperature display error: < 2%. Operating voltage: ~AC200V–250V; Power consumption: ~AC220V, 1W. Ambient temperature: 0°C–60°C; Ambient humidity: below 85% RH. Two types of housing: Chassis type (Type 1): 230 x 162 x 50 (MM), weight < 1000G. Flush-mounted panel (Type 2): 230 x 162 x 10 (MM), weight < 1000G. more>
