Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine development, in particular to a material conveying belt dust suppression and cleaning system. BACKGROUND

[0002] In the power, metallurgy, coal, building materials, mining and other industries, there are a large number of belt material conveying systems. When the belt material conveying system conveys materials containing fine dust and particles, due to the shaking of the belt conveying system itself, the fine and dry dust and particles will be detached from the surface of the conveyed material due to inertia, air flow disturbance and other effects in the belt shaking, and fly into the atmosphere. When the belt stops running, part of the fine dust and particles adhere to the surface of the belt. When the belt starts, due to the stretching, shaking and air flow disturbance of the belt itself, the dust and particles are detached from the surface of the belt and fly into the atmosphere.

[0003] Chinese patent application with publication number CN 104150194 A proposes a material conveying belt dust suppression and cleaning system, which includes a material conveying belt provided with a cleaning shell, the material conveying belt passing through the cleaning shell; a cleaning device for cleaning the material conveying belt is arranged in the cleaning shell; the cleaning shell is also provided with a air supply pipe and a dust suction pipe; the cleaning system is also provided with a fan, the fan is connected with the air supply pipe through a first air supply pipeline, and the fan is connected with the dust suction pipe through a second air supply pipeline, and the air supply pipe and the dust suction pipe are arranged in the cleaning shell.

[0004] The cleaning of the dust suppression and cleaning system uses a cleaner and high-pressure gas. Compared with the original wet cleaning process, water resources are saved, and secondary pollution caused by polluted water is avoided. The system is more suitable for belt cleaning of belt material conveying systems in water-deficient areas.

[0005] The rotary cleaner, rotary cleaner and dust blowing nozzle of the dust suppression and cleaning system are installed in the shell. When the system is running, the shell is in a negative pressure state. The dust cleaned by the drum cleaner and the dust blowing nozzle will not spread to the surrounding air and pollute the surrounding air in the negative pressure state.

[0006] The above system is based on the cleaning of the belt after the belt is polluted after the material is loaded onto the conveying belt in an open environment. The inventor believes that instead of dust suppression when the belt is cleaned after the belt is polluted, why not perform dust suppression treatment when the material is loaded. This way, the effect is better, and the workload of cleaning the belt later can be reduced. Therefore, a material conveying belt dust suppression and cleaning system is proposed. SUMMARY

[0007] To solve the technical problems proposed in the background art, the present application provides a material conveying belt dust suppression and cleaning system.

[0008] The dust suppression and cleaning system for the material conveying belt is achieved by the following technical scheme: a material feeding bin arranged above the conveying belt and a supporting platform arranged in the conveying belt;

[0016] When the material in the material feeding bin moves downward to drive the rotation of the butt joint pipe, the fan blade is driven to rotate, so that the inside of the mounting pipe is in a negative pressure state to absorb dust.

[0017] Through the above structure, the blade can be driven to rotate when the material descends, so that the connecting pipe rotates, the fan blade rotates, the installation pipe maintains a negative pressure state, the dust in the feed bin is absorbed into the installation pipe for collection, and finally the dust enters the treatment box.

[0018] As a further improvement of the above scheme, the installation pipe is detachably connected to the inner wall of the feed bin away from the one end of the connecting pipe. Through the above design, the installation pipe and the connecting pipe can be conveniently disassembled for regular cleaning of dust therein, improving the service life and use effect of the device.

A bayonet is located at the bottom of the frame, and a sealing ring is detachably embedded in the bayonet. The sealing ring stores a sealing liquid with a certain viscosity. Several perforations communicating with the bayonet are opened on one side of the bottom frame. The inner end of each perforation has an flared end, and an operating rod is movably inserted through each perforation.
