Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a cleaning device for a wet pulp belt conveyor. Background Art

[0002] Belt conveyors can be used to transport bulk materials in the chemical, metallurgical, papermaking, construction and other industries. When the conveyed materials are water-rich or sticky substances, such as cement, sludge, coal powder, wood pulp, etc., the commonly used scraper cleaners and roller brush cleaners are difficult to clean the belts, resulting in materials attached to the belts during operation, causing the belt conveyor to deviate and slip, greatly reducing the service life of the belts and easily causing damage to rollers and drums. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a wet pulp belt machine cleaning device which has a reasonable structural design, can effectively clean the wet pulp material attached to the belt, and can automatically return the cleaned material to the head funnel.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a wet slurry belt conveyor cleaning device, including a collecting hopper fixedly installed on the belt conveyor frame, and the belt on the belt conveyor passes through the collecting hopper after the head funnel completes unloading; a belt pressing roller and a belt supporting roller for limiting the belt running trajectory are installed on the return path of the belt; a nozzle, a first cleaner and a second cleaner are sequentially arranged in the collecting hopper along the return running direction of the belt, and the nozzle is connected to a water source through a water pipe; a cleaning material return conveyor is arranged at the bottom of the collecting hopper, and the discharge port of the cleaning material return conveyor is connected to the head funnel.

[0005] As a preferred technical solution, the belt holding roller is installed on the upper part of the collecting hopper, and the belt supporting roller is installed on the side of the collecting hopper.

[0006] As a preferred technical solution, the first cleaner is an alloy cleaner.

[0007] As a preferred technical solution, the second sweeper is a polyurethane sweeper.

[0008] As a preferred technical solution, the cleaning material return machine is a screw conveyor.

[0009] As a preferred technical solution, the aggregate hopper includes a first cleaning area, a second cleaning area and an aggregate area, the nozzle and the first cleaner are installed in the first cleaning area, and the second cleaner is installed in the second cleaning area.

[0010] As a preferred technical solution, the spray angle of the nozzle can be adjusted.

[0011] Due to the adoption of the above technical scheme, the utility model has at least the following beneficial effects: a collecting hopper is installed on the frame of the belt conveyor, and the belt passes through the collecting hopper after the head funnel completes unloading, and a belt pressing roller and a belt supporting roller for limiting the running track of the belt are installed on the return path of the belt; a nozzle, a first cleaner and a second cleaner are sequentially arranged in the collecting hopper along the return running direction of the belt, and the nozzle is connected to the water source through a water pipe; a cleaning material return conveyor is arranged at the bottom of the collecting hopper, and the discharge port of the cleaning material return conveyor is connected to the head funnel. Through the above structural design, when the belt that has completed unloading passes through the high-pressure nozzle, the high-pressure nozzle generates a fan-shaped high-pressure water column, which can effectively wash the belt; then it passes through the alloy cleaner, which can clean the dirt and debris with greater viscosity; and then passes through the polyurethane cleaner, which has a good cleaning effect on the fine particles and sticky materials remaining on the belt; the cleaned materials are collected through the collecting hopper and transported to the head funnel through the screw conveyor, thereby completing the entire cleaning process.

[0012] The utility model has a simple structure and is easy to use. It cleans the belt through three different cleaning devices, which can effectively solve the problem that wet slurry materials are not easy to clean due to their viscosity. The cleaned materials can automatically flow back to the head funnel to avoid secondary processing, thus saving manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following drawings are only intended to illustrate and explain the present invention, and do not limit the scope of the present invention.

[0016] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0017] like Figure 1 and Figure 2As shown, the wet pulp belt conveyor cleaning device comprises a collecting hopper 1, which is fixedly mounted on a frame 3 of the belt conveyor through two mounting seats 2, and a belt 4 on the belt conveyor passes through the collecting hopper 1 after the head funnel 5 completes unloading; a belt holding roller 6 and a belt supporting roller 7 for limiting the belt running track are installed on the return path of the belt 4, the belt holding roller 6 is installed on the upper part of the collecting hopper 1, and the belt supporting roller 7 is installed on the side of the collecting hopper 1, and the belt running track is limited by the belt holding roller 6 and the belt supporting roller 7 to prevent the belt from jumping up and down during operation;
