Because the utility model discloses a cross-section of wind channel sticky tape is the U type, and both ends thickening part closely laminates with conveyor belt to the friction through wind channel sticky tape and conveyor belt drives the wind channel sticky tape and rotates, makes wind channel sticky tape and conveyer belt approximate relatively static, reaches the harmless effect of wind channel sticky tape.
Description
Technical Field
The utility model relates to a conveying equipment especially relates to a dry and fine bulk material belt feeder return stroke air-blast cleaning device.
Background
The belt conveyor is the most important bulk material conveying and loading and unloading equipment, can be widely applied to the industrial fields of mines, metallurgy, building materials, chemical industry, electric power, food processing and the like, and can be widely applied to coal mines, metal mines, steel enterprises, ports, cement plants and the like. Traditional scraper formula sweeper can't thoroughly clear away the dry thin clout of belt return stroke, and the air-blowing sweeper on the present market keeps certain interval and contained angle for air knife and belt, and the high-speed air current that blows out through the air knife is beaten on the belt, clears up the sizing of belt. Such a structure is simple but has a large energy loss and may cause secondary pollution (dust emission).
Disclosure of Invention
An object of the utility model is to provide a clean effectual fine and dry bulk material belt feeder return stroke air-blast cleaning device. Has excellent cleaning effect on dry materials with low adhesion.
In order to achieve the above object, the technical solution of the present invention is:
the utility model relates to a return air-blowing cleaning device for a dry and fine bulk material belt machine, which comprises a carrier roller bracket, an air pipe bracket, a carrier roller, an air duct adhesive tape, an air pipe and an air-blowing knife; the carrier roller support is fixed with the air pipe support together, the carrier roller is rotatably installed on the carrier roller support, the air duct adhesive tape is wound on the carrier roller, the air pipe is fixedly installed on the air pipe support, two ends of the air pipe penetrate out of the air pipe support so as to be connected with an external air source, the air blowing knife is fixedly sleeved on the air pipe, an air inlet of the air blowing knife is communicated with an air pipe cavity, and an air outlet of the air blowing knife faces the air duct adhesive tape.
The two sides of the air duct adhesive tape are thickened to form a thickening layer.
The two carrier rollers are rotatably arranged on the carrier roller bracket and are arranged in parallel and at intervals, and the air duct rubber belt is wound on the two carrier rollers.
After the scheme is adopted, because the utility model discloses remain original air-blowing cleaning system's characteristics, and fine solution its original air-blowing cleaning system not enough. The utility model discloses a cross-section of wind channel sticky tape is the U type, and both ends thickening part closely laminates with conveyor belt to the friction through wind channel sticky tape and conveyor belt drives the wind channel sticky tape and rotates, makes wind channel sticky tape and conveyer belt approximate relative static, reaches the harmless effect of wind channel sticky tape, is thinner part in the middle of the wind channel sticky tape, keeps certain clearance with conveyor belt, forms airtight wind channel, so, has following advantage:
1. no matter how the surface condition of the belt is, the air knife is in seamless contact with the surface of the belt, and a certain contact stroke is provided, so that return surplus materials can be thoroughly removed.
2. The air blowing knife does not adopt the contact scraping mode of a scraper of a traditional sweeper, and does not cause any abrasion to the belt.
3. The air duct is cleaned in a sealed mode, high-speed airflow can be concentrated in the air duct, energy loss can be avoided almost, and the cleaning effect is improved greatly. When the air flow sweeps the excess material, the material does not fly upwards and overflow, and automatically returns to the head funnel without generating secondary dust.
The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description
As shown in fig. 1-4, the utility model relates to a return air-blowing cleaning device for a dry and fine bulk material belt conveyor, which comprises a carrier roller bracket 1, an air pipe bracket 2, two carrier rollers 3, an air duct adhesive tape 4, an air pipe 5 and an air-blowing knife 6.
The roller support 1 is fixed on a funnel at the head of the belt conveyor 10 (as shown in fig. 5-7), the roller support 1 is fixed with the air pipe support 2, the two rollers 3 are rotatably arranged on the roller support 1 and are arranged in parallel at intervals, and the air duct adhesive tape 4 is wound on the two rollers 3. Trachea 5 fixed mounting on trachea support 2 and trachea 5's both ends wear out trachea support 2 to external air supply, air-blowing sword 6 is fixed cup joint on trachea 5 and air-blowing sword 6's inlet port and 5 lumen intercommunications of trachea, air duct sticky tape 4 is facing to air duct 61 of air-blowing sword 6.
The two sides of the air duct adhesive tape 4 are thickened to form a thickening layer 41, so that the thickening layer 41 can be tightly attached to the belt 101 in the belt conveyor 10, and the air duct adhesive tape 4 is driven to move by the movement of the belt 101, so that the air duct adhesive tape 4 and the belt 101 are in a relatively static state.
The utility model discloses a theory of operation:
as shown in fig. 8-10, the cross-section of the air duct adhesive tape 4 of the present invention is U-shaped, the two end thickening layers 41 are tightly attached to the belt 101, and the air duct adhesive tape 4 is driven to rotate by the friction between the air duct adhesive tape 4 and the belt 101, so that the air duct adhesive tape 4 is approximately relatively static with the belt 101, and the effect that the air duct adhesive tape 4 is not damaged is achieved. The middle of the air duct adhesive tape 4 is a thin part, and a certain gap is kept between the air duct adhesive tape 4 and the belt 101, so that the air duct adhesive tape 4 and the belt 101 form a closed air duct M.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
