Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal, and in particular relates to an ultra-low emission bag dust collector for mining. Background Art

[0002] During the mining process of coal mines, a large amount of dust particles are generated. Bag dust collectors are usually used to filter and collect dust particles. Bag dust collectors are a dry dust filtering device that uses the filtering effect of fiber fabrics to filter dust-laden gas. When the dust-laden gas enters the bag and filter, the large particles and high specific gravity of the dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained and the gas is purified. When the existing bag dust collector is in use, the dust on the outside of the dust bag is blown away by the blowing mechanism. The dust is collected under the dust bag, but after a long period of use, the existing equipment has accumulated a lot of dust. It is difficult, time-consuming and labor-intensive to rely solely on the blowing mechanism to clean the dust on the dust bag. In addition, when the exhaust gas enters the bag chamber through the air inlet, the dust bag facing the air inlet is directly impacted by the exhaust gas and filters the exhaust gas, while the other dust bags facing away from the air inlet participate in the exhaust gas filtration to a small extent. The dust bags are unevenly filtered and are easily damaged by the impact of exhaust gas for a long time. For this reason, we propose an ultra-low emission bag dust collector for mining.

[0008] Furthermore, the transmission assembly includes a box body fixedly installed in the air inlet duct, and the box body is rotatably connected with a bevel gear 1 and a bevel gear 2 that mesh with each other for transmission. The bevel gears are coaxially fixedly assembled on the transmission shaft, and the transmission shaft passes through the box body and the air inlet duct to the outside and is rotatably connected to the support rod, and the support rod is fixedly installed on the top of the dust removal box body. Pulley 1 and pulley 2 are coaxially fixedly assembled on the connecting shaft and the transmission shaft respectively, and the pulley 1 and pulley 2 are connected by a transmission belt. The bevel gear 2 is coaxially fixedly assembled on the rotating shaft, and the rotating shaft passes through the box body and is coaxially fixedly assembled on the fan blades.

[0010] The utility model adopts the above-mentioned structure, and the technical progress achieved by it compared with the prior art is that the utility model first sends the exhaust gas to be treated into the dust collection box through the intake pipe, and then uses the dust bag fixed on the circular partition plate to filter the exhaust gas, and then uses the exhaust pipe to discharge it, and starts the first driving mechanism and the second driving mechanism. The first driving mechanism drives the cam to rotate. At this time, the movable ring and the circular partition plate are repeatedly moved up and down by the cam under the action of the elastic component, and the dust bag is vibrated by the vibrating circular partition plate, so that the dust particles adhered to the dust bag are shaken down to the bottom of the dust collection box cavity for collection.
