Description

Self-cleaning dustproof device

Technical Field

The utility model belongs to the technical field of the control valve, especially, relate to a self-cleaning dust keeper.

Background

At present, domestic customers in the industries such as thermal power plants, mines, coal mines, docks, cement plants, metallurgy and the like generally adopt belt conveyors to convey a large amount of materials, and because of the requirements of long-distance conveying and material treatment processes, a plurality of multi-stage belt conveyors are required to convey the materials.

This just leads to a problem, and in the material handing-over transportation of last level belt and next level belt, can design one and fall the casing, nevertheless because the higher and lower level belt must have the drop, the material is falling the in-process in falling the casing, must lead to the condition of raise dust fluffy ash.

To this kind of raise dust fluffy grey condition, generally adopt at present to set up in the casing that falls and turn over the board door (the material whereabouts oppresses to turn over the door and open and let the material pass through, closed when no material), perhaps set up in the casing upper shed that falls and spray the dust fall. The disadvantages of these two main flow measures are as follows:

1. the turnover door is of a mechanical structure, and materials are washed for a long time, so that the mechanical property is reduced quickly, the abrasion is huge, the materials are easy to accumulate on the turnover door, the fatigue deformation of the mechanism is quick, the tightness cannot be realized, and the effect is lost.

2. Spray set, because the installation environment dust is huge, very easy nature is often blockked up the shower nozzle, influence water atomization effect, including lack reliable measure and judge whether there is the material to pass through, can only open for a long time, waste water is not said, still can lead to the site environment muddy embarrassment, including can not avoid also being infected with a large amount of moisture on the material, can greatly influence material economic efficiency, if this kind of material of coal adds water excessively, will reduce the calorific value during the burning, seriously influence like thermal power plant, the economic benefits of self-contained power plant.

Based on the current situation, I have researched and developed novel automatic environmental protection dustproof equipment: automatic dust keeper.
