An environmentally friendly coal dust collection equipment for coal mine sites

Abstract

The invention discloses an environment-friendly pulverized coal collection equipment for coal mine construction sites, which includes an isolation device, and a compression device is arranged inside the isolation device; the filter device is driven to rotate quickly by a driving device, so that the pulverized coal on the filter device can be Centrifugal motion is performed under the action of centrifugal force, and the centrifugally moving pulverized coal will hit the inner wall of the blower device to ensure that the pulverized coal will not stay on the filter device for a long time and accumulate, so that the filter device maintains good permeability and does not It needs to be shut down for cleaning, which saves time and effort. The cleaning device is rotated quickly through the filter device, so that the cleaning device can scrape off the coal powder adhered to the inner wall of the blower device, and the scraped coal powder falls on the surface of the filter device again. In this way, the pulverized coal is beaten repeatedly so that it is compacted into large briquettes to ensure that the pulverized coal released will not cause dust pollution again, which improves the practicability of the environmentally friendly pulverized coal collection equipment for coal mine sites.

Description

technical field [0001] The invention relates to the field of pulverized coal collection equipment, more specifically, to an environmentally friendly pulverized coal collection equipment for coal mine sites. Background technique [0002] Coal is the most important solid fuel and a kind of combustible organic rock. It is a lush plant growing in a certain geological age. In a suitable geological environment, it gradually accumulates into a thick layer and is buried in the bottom of the water or in the sand. Formed through natural coalification over a long geological age, the place used for mining coal is called a coal mining site. During the process of mining coal, a large amount of coal powder will be produced, and the coal powder particles will be formed with the flow of air. Coal dust is polluted by dust. Coal miners work in such an environment. After a long time, they are prone to silicosis, which seriously endangers the health of coal miners. Therefore, coal dust needs to ...

Problems solved by technology

[0003] At present, people usually install bag dust collectors on coal mine sites to collect coal dust in the air. During work, the air containing coal dust enters the cloth bag under the action of the fan, and the coal dust is intercepted by the cloth bag, and the air passes through the cloth bag and is discharged. With the prolongation of use time, more and more pulverized coal will be adsorbed on the bag, which will not only reduce the permeability of the bag, increase the air resistance, and increase the energy consumption, but also need to shut down the bag to vibrate it to It is time-consuming and labor-intensive to remove the coal powder adhered to the inner wall of the bag. At the same time, the coal powder in the bag is put into the bucket truck from the bottom of the dust collector, and the bucket truck transports it to the storage area. Dust rises and pollutes the environment again, so it is urgent to design an environmentally friendly coal dust collection equipment for coal mine sites
