Description

Technical Field

[0001] This utility model relates to the field of environmental protection, specifically to a transfer device for sludge drying treatment. Background Technology

[0002] After wastewater treatment, the water-containing sludge needs to undergo drying. The sludge drying process typically requires multiple machines to dry the water-containing sludge in stages to gradually remove moisture and meet factory standards. During staged drying, belt conveyors are needed to receive and transfer sludge from adjacent stages; for example, a sludge transfer conveyor belt can be installed between the drying sections of a thin-layer sludge dryer and a belt dryer. The belt conveyor includes two rollers, a conveyor belt, and an internal belt support. The conveyor belt is wound around the two rollers and kept taut. The internal belt support is located inside the conveyor belt and provides support to prevent it from collapsing.

[0003] During the sludge drying process, sludge and dust inevitably fall between the conveyor belt and the inner support of the belt during long-term use. When the belt conveyor is shut down for maintenance, the conveyor belt and the inner support remain relatively stationary. Sludge and dust fill the gap between the conveyor belt and the inner support, causing them to stick together. This will increase the resistance to restarting the belt conveyor, and in severe cases, it may prevent the belt conveyor from restarting.

[0004] Existing technology uses manual peeling to separate the conveyor belt from the internal support to solve the problem of conveyor belt adhesion. However, if the belt is peeled off before starting, it may still re-adhere to the internal support; and peeling it off while the conveyor belt is running poses a safety risk. Utility Model Content

[0005] To address the above technical problems, this utility model provides a relatively safer and more effective conveyor belt adhesion removal device to assist in the smooth restart of the belt conveyor. The main technical solution adopted is as follows: A sludge conveyor belt shutdown and restart auxiliary device includes two vertically arranged and opposite support plates. Two parallel rotating rollers are provided between the two support plates. The belt is fitted onto the two rotating rollers. A belt support is provided inside the belt and is fixedly connected to the two support plates. The outer surface of the belt support is in contact with the inner surface of the belt. The key feature is that a belt stripping piece is movably inserted through the support plates. The inner end of the belt stripping piece extends to the inner side of the support plate and faces the contact surface between the belt support and the belt. The outer end of the belt stripping piece extends to the outer side of the support plate. An elastic telescopic member is connected to the outer end of the belt stripping piece. The telescopic direction of the elastic telescopic member is consistent with the insertion direction of the belt stripping piece.

[0006] When the sludge conveyor belt is stopped and restarted, pressing the elastic telescopic component causes the inner end of the belt stripper to extend between the belt support and the belt, thereby separating the two. Since the belt stripper is set on the support plate, the safety risk can be significantly reduced, and the belt can be kept in a stripped state during startup and restart, which facilitates the restart of the belt conveyor.

Detailed Implementation

[0008] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0009] like Figure 1 , 2 As shown in Figure 3, a sludge conveyor belt shutdown and restart auxiliary device includes two vertically arranged and opposite support plates 1. Two parallel rotating rollers 2 are provided between the two support plates 1. The belt 3 is fitted onto the two rotating rollers 2. A belt support 4 is provided inside the belt 3. The belt support 4 is fixedly connected to the two support plates 1. The outer surface of the belt support 4 is in contact with the inner surface of the belt 3. The device is characterized in that: a belt peeling piece 5 is movably inserted through the support plate 1. The inner end of the belt peeling piece 5 extends to the inner side of the support plate 1 and faces the contact surface of the belt support 4 and the belt 3. The outer end of the belt peeling piece 5 extends to the outer side of the support plate 1. An elastic telescopic member 6 is connected to the outer end of the belt peeling piece 5. The telescopic direction of the elastic telescopic member 6 is consistent with the insertion direction of the belt peeling piece 5.

[0010] A specific embodiment of an elastic telescopic component 6 is as follows: The elastic telescopic component 6 includes a guide post 61, a sleeve 62, and a spring 63. The length direction of the guide post 61 is consistent with the insertion direction of the belt stripper 5. The guide post 61 is located outside the support plate 1. One end of the guide post 61 is fixedly connected to the outer side of the support plate 1, and the other end of the guide post 61 is expanded to form an anti-detachment head. The sleeve 62 is movably sleeved on the guide post 61, and the sleeve 62 is located between the anti-detachment head and the support plate 1. The spring 63 is sleeved on the guide post 61 between the sleeve 62 and the support plate 1. The outer end of the belt stripper 5 is fixedly connected to the sleeve 62. The sleeve 62 moves forward and backward along the length direction of the guide post 61, thereby driving the belt stripper 5 to move forward and backward. When the sleeve 62 is pressed, causing the belt peeler 5 to move inward toward the support plate 1, the spring 63 is simultaneously compressed to store energy. When the sleeve 62 is released, the spring 63 automatically pushes the sleeve 62 and the belt peeler 5 back to their original positions. To facilitate operation, an enlarged pressure plate 64 is fixedly connected to the outer wall of the sleeve 62.

[0011] A structure in which a belt stripper 5 is movably inserted through a support plate 1 is as follows: the support plate 1 is provided with a guide through hole, the guide through hole matches the belt stripper 5, and the belt stripper 5 is movably inserted through the guide through hole.

[0012] To further improve safety, manual operation of the elastic telescopic component 6 should be avoided. The auxiliary device also includes a peeling plate pushing mechanism 7, which acts on the enlarged pressure plate 64 to push the belt peeling plate 5 forward and outward.

[0013] The peeling sheet pushing mechanism 7 can be a pneumatic pushing component (e.g., a cylinder), a hydraulic pushing component (e.g., a hydraulic cylinder), or an electric pushing component (e.g., a linear motor). A preferred structure of the peeling sheet pushing mechanism 7 is as follows: the peeling sheet pushing mechanism 7 includes a water tank 71, a water pump 72, and a high-pressure water pipe 73. The inlet end of the high-pressure water pipe 73 is connected to the water tank 71 for water intake, and the outlet end of the high-pressure water pipe 73 faces the enlarging pressure plate 64 for water discharge. The water pump 72 is installed on the high-pressure water pipe 73. After the water pump 72 is turned on, the water jet from the outlet end of the high-pressure water pipe 73 impacts the enlarging pressure plate 64, thus pushing the enlarging pressure plate 64. The advantage of this structure is its simplicity and durability.

[0014] To further improve the belt stripping effect, a high-pressure nozzle 8 is also fixed on the support plate 1. The water outlet of the high-pressure nozzle 8 extends to the inside of the support plate 1 and faces the contact surface of the belt support 4 and the belt 3. The water inlet of the high-pressure nozzle 8 is connected to the output of the water pump 72 through a pipe. Preferably, the target direction of the water outlet of the high-pressure nozzle 8 is consistent with the target direction of the inner end of the belt stripping piece 5.

[0015] Since the belt stripper 5 cannot be set too long, it mainly strips the edge of the belt 3, resulting in limited stripping effect. However, the high-pressure water jet from the high-pressure nozzle 8 can penetrate along the gaps created by the stripping at the edge of the belt 3, increasing the stripping depth and improving the stripping effect. The structure is simple and efficient.

[0016] Beneficial effects: The technical solution of this utility model uses a combination of mechanical and hydraulic stripping to separate the belt of the belt conveyor from the adhesive base, thereby reducing the resistance when the belt conveyor starts and assisting in the smooth restart of the belt conveyor after shutdown.

[0017] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
