Description

Rapid loading system negative pressure dust removal device

technical field

The utility model relates to a negative pressure dedusting device for a fast loading system, which belongs to the field of dedusting equipment.

Background technique

The coal industry produces a large amount of dust in the production process. The main links of dust generation include: transportation, transfer of transportation equipment, lifting and unloading, transfer points of belt conveyors, and unloading points of coal bunkers. When the coal falls, the coal is crushed, and it will continue to be crushed during the process of coal loading, transportation and reloading, and coal dust will continue to be generated. With the improvement of the degree of mechanization and reasonable centralized production, the generation of coal dust is very large. Dust not only pollutes the working environment, reduces the visibility of the production site, but also poses a hazard to human health. Some are also combustible and explosive, and may explode under certain conditions. It will also accelerate the damage of mechanical and electrical equipment and shorten precision. The service life of instruments and meters. The current dust removal methods are generally divided into two types, one is dry dust removal method: including gravity settling chamber, inertial dust collector, electrostatic precipitator, bag filter, cyclone dust collector; the second is wet dust removal method: including double spray tower , Impact dust collector, Venturi detergent, foam dust collector and water film dust collector, etc. At present, the most commonly used ones are cyclone separators, electrostatic precipitators and bag filter. But there is no suitable dedusting device designed for the fast loading system of the coal industry at present.

Contents of the invention

The purpose of the utility model is to provide a negative pressure dust removal device for the fast loading system in order to solve the problem of dust pollution generated during the loading process of the fast loading system in the coal industry.

The purpose of this utility model is achieved in the following ways:

The utility model comprises a filter, a Roots blower unit, a dust collection cover and a wire winch, and is characterized in that the Roots blower unit communicates with the filter through a pipeline, a coal dust recovery device is installed under the filter, and the dust collection of the filter The mouth is connected with a hard pipe, and the end of the hard pipe is connected with a telescopic hose, and the end of the telescopic hose is connected with the dust collection hood. .

Inside the filter is a bag filter.

The utility model has the advantages that: according to the fine, dry and non-fibrous characteristics of coal dust, the bag dust removal method is used to remove dust, and the configuration of the steel wire winch and the dust collection cover meets the needs of the rapid loading system in the coal industry during the loading process. The need for dust removal prevents dust pollution during the loading process.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

With reference to the accompanying drawings, the utility model includes a filter 1, a Roots blower unit 2, a dust collection cover 3, and a wire winch 8. The Roots blower unit communicates with the filter through a pipeline, and a coal dust recovery device 6 is installed below the filter. The dust collection port of the filter is connected with a hard pipe 7, and the end of the hard pipe is connected with a telescopic hose 5, and the end of the telescopic hose is connected with the dust collection hood. The wire winch is erected above the dust collection hood, and the dust collection hood passes through Wire rope 9 is suspended on the wire winch.

In application, the wire winch is installed under the loading tower, and the dust collection hood is hung on the winch with a wire rope. When it is ready to load, the dust collection cover is lowered to the loading position synchronously through the wire winch and the chute of the fast loading system. When it falls into wagon 4, the Roots blower unit starts to work, the dust is sucked into the gas collecting hood, enters the filter through the pipe, and the dust after the filter gathers on the surface of the bag, settles down due to the effect of gravity, and falls into the coal dust recovery device. The filtered dust-free gas is discharged into the atmosphere.
