It also includes a second polyurethane P-type cleaner acting on the lower surface of the return belt and arranged in sequence from the surface increasing roller to the return flat support, a carbon tungsten alloy P-type cleaner and a water removal cleaner.

[0006] By adopting the above technical scheme, the second polyurethane P-type cleaner is used to clean the flaky sticky materials on the belt, the carbon tungsten alloy P-type cleaner is used to clean the granular thin materials attached to the belt, and the water removal cleaner is used to drain the clear water on the belt surface. The polyurethane H-type cleaner and the first polyurethane P-type cleaner are combined to form a more effective cleaning system, which improves the self-cleaning ability of the belt conveyor.

[0008] By adopting the above technical solution, a certain tension is generated when the belt passes between the back-pressure flat support and the return flat support to slow down the jumping of the belt during operation, thereby ensuring a stable working environment for the second polyurethane P-type cleaner, the carbon tungsten alloy P-type cleaner and the water removal cleaner.

[0009] Optionally, the lateral distance between the counter-pressure flat support and the return flat support ranges from 2 to 3 m.

[0024] The following is combined with Figure 1 The utility model is described in further detail.

[0025] The utility model embodiment discloses a belt conveyor adhesive material centralized automatic cleaning unit. Figure 1 The belt conveyor 1 includes a head roller 10, a surface increasing roller 11 and a return flat support 12 which are arranged in sequence. A belt 13 is wound around the head roller 10, the surface increasing roller 11 and the return roller 12. The surface increasing roller 11 and the return roller 12 are located at the lower side of the return belt 13. The head roller 10 is located in the hopper 2, so that the material on the belt 13 falls directly into the hopper 2 after falling.

[0026] Reference Figure 1 The centralized automatic cleaning unit for sticky materials on the belt conveyor includes a cleaning component 3 for cooperating with the belt conveyor 1. The cleaning component 3 includes a polyurethane H-type cleaner 30 arranged in the funnel 2 and located at the unloading position of the belt 13. A first polyurethane P-type cleaner 31 is arranged below the head roller 10. A second polyurethane P-type cleaner 32, a carbon-tungsten alloy P-type cleaner 33 and a water removal cleaner 34 are arranged in sequence from the surface-increasing roller 11 to the direction of the return flat support 4. The installation distances between the second polyurethane P-type cleaner 32 and the carbon-tungsten alloy P-type cleaner 33, and between the carbon-tungsten alloy P-type cleaner 33 and the water removal cleaner 34 are not less than 300 mm to leave enough space for material throwing and inspection and maintenance.

[0027] Reference Figure 1 The second polyurethane P-type cleaner 32, the carbon tungsten alloy P-type cleaner 33 and the water removal cleaner 34 are located between the surface increasing roller 11 and the return flat support 4, and all three act on the lower surface of the return belt 13. The second polyurethane P-type cleaner 32 is used to clean the sheet-like sticky materials on the belt 13, the carbon tungsten alloy P-type cleaner 33 is used to clean the granular thin materials attached to the belt 13, and the water removal cleaner 34 is used to drain the clear water on the surface of the belt 13.

[0028] Reference Figure 1A back-pressure flat support 14 is also arranged between the surface increasing roller 11 and the return flat support 12. The back-pressure flat support 14 is located on the upper side of the return belt 13, and the second polyurethane P-type cleaner 32, the carbon tungsten alloy P-type cleaner 33 and the water removal cleaner 34 are located between the back-pressure flat support 14 and the return flat support 12. The lateral distance between the back-pressure flat support 14 and the return flat support 12 is 2-3m, and the vertical distance between the bottom edge of the back-pressure flat support 14 and the top edge of the return flat support 12 is 1-2mm smaller than the thickness of the belt 13, so that the belt 13 generates a certain tension when passing between the back-pressure flat support 14 and the return flat support 12, so as to slow down the jumping of the belt 13 during operation, thereby ensuring a stable working environment for the second polyurethane P-type cleaner 32, the carbon tungsten alloy P-type cleaner 33 and the water removal cleaner 34.

[0029] Reference Figure 1 An automatically controlled plate conveyor belt 4 is installed below the head roller 10. The falling materials are cleaned by the second polyurethane P-type sweeper 32, the carbon tungsten alloy P-type sweeper 33 and the water removal sweeper 34 and fall onto the plate conveyor belt 4. The distance from the discharge end of the plate conveyor belt 4 to the funnel 2 is not less than 200 mm, and the distance between the discharge end of the plate conveyor belt 4 and the return flat support 12 is not less than 3 m, so as to ensure that all the cleaned materials fall into the effective working range of the plate conveyor belt 4, completing the functional connection between the cleaning component 3 and the plate conveyor belt 4.

[0030] Reference Figure 1 The plate conveyor 4 adopts a chain-type rotary structure to achieve the purpose of occupying a small space. The plate conveyor 4 is equipped with a remote communication and control system. The timed self-starting operation program is compiled or called by PLC. The remote centralized control system involves a user interaction interface. By setting the start interval and operation duration of the plate conveyor 4, the material automatic centralized processing function matching the corresponding parameters according to the material characteristics and spilling conditions is realized. The above remote communication and control system can select mature designs in the existing technology.

[0031] The implementation principle of the centralized automatic cleaning unit for sticky materials on the belt conveyor of the utility model embodiment is as follows: the centralized automatic cleaning unit for sticky materials on the belt conveyor improves the self-cleaning ability of the belt conveyor and has the function of automatically recycling and transporting the cleaned materials. The materials are transported to the hopper 2 by the belt 13, and most of the materials fall directly into the hopper 2. The other part of the materials adhering to the return belt 13 are cleaned by the polyurethane H-type cleaner 30, the first polyurethane P-type cleaner 31, the second polyurethane P-type cleaner 32, the carbon tungsten alloy P-type cleaner 33 and the water removal cleaner 3 in turn before falling. The addition of the second polyurethane P-type cleaner 32, the carbon tungsten alloy P-type cleaner 33 and the water removal cleaner 3 changes the defects of insufficient cleaning capacity and single cleaning function of the first and second cleaners in the traditional design, and achieves the purpose of centralized treatment of sticky materials and water materials.

[0032] The materials that fall after being cleaned by the polyurethane H-type cleaner 30 can directly fall into the hopper 2, and the materials that fall after being cleaned by the other cleaners can fall onto the plate conveyor 4, and are transported by the plate conveyor 4 to the hopper 2 for discharge, thus solving the problem of automatic recovery of materials in the concentrated spilling area of ​​the head. The back pressure flat support 14 cooperates with the return flat support 12 to adjust the original conventional return roller process layout, so that the return belt 13 generates a certain tension, reduces the vibration of the belt 13, and enables the second polyurethane P-type cleaner 32, the carbon tungsten alloy P-type cleaner 33 and the water removal cleaner 34 to contact and clean the belt 13 more stably, thus achieving a more thorough cleaning effect.

[0033] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
