Environment-friendly pulverized coal collecting equipment for coal mine construction site

Abstract

The invention discloses environment-friendly pulverized coal collecting equipment for a coal mine construction site, which comprises an isolation device, and a compression device is arranged in the isolation device; a filtering device is driven by a driving device to rotate quickly, so that pulverized coal on the filtering device can do centrifugal motion under the action of centrifugal force, thepulverized coal in centrifugal motion can impact the inner wall of a blower device, the pulverized coal is prevented from staying on the filtering device for a long time and being accumulated, and the filtering device keeps good permeability; shut-down for cleaning is not required, time and effort can be saved, the cleaning device is driven by the filtering device to quickly rotate, so that the cleaning device can scrape off pulverized coal adhered to the inner wall of the air blowing device, the scraped pulverized coal falls on the surface of the filtering device again, and the pulverized coal is repeatedly beaten to be compacted into large-particle coal balls; and it is ensured that discharged pulverized coal cannot form flying dust pollution again, and the practicability of the environment-friendly pulverized coal collecting equipment for the coal mine construction site is improved.

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
