Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a high-efficiency bag dust collector. Background Art

[0002] A bag dust collector is also called a filter dust collector. It is a dry and efficient dust collector. It is a dust removal device that uses bag filter elements made of fiber woven materials to capture solid particles in dust-containing gas. Its working principle is that dust particles are intercepted by colliding with the fibers due to inertia when they pass around the filter cloth fibers. When the dust-containing gas enters the bag dust collector, large particles and high specific gravity dust settle due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, thereby purifying the gas.

[0003] Publication (announcement) No.: CN219502226U discloses a high-efficiency bag dust collector, including a body, an air inlet is provided at the left end of the body, and an electromagnetic pulse valve is provided at the upper end of the air inlet, a fixed plate is provided at the right end of the electromagnetic pulse valve, and an air outlet is provided at the right end of the fixed plate, and a bag is provided below the fixed plate, a porous plate is provided at the lower end of the bag, and a dust cleaning hopper is provided at the lower end of the porous plate, so that the pressure roller rotates while moving with the movable block to clear the through holes on the surface of the porous plate, which is convenient for long-term use of the porous plate and ensures normal filtration of dust-containing gas.

[0004] Although the above scheme has the advantage of ensuring normal dust gas filtration, dust is easily accumulated on the surface of the ball screw during use. When the movable block slides along the length direction of the ball screw, the contact surface is easily subjected to greater friction. Long-term use can easily cause damage to the surface of the ball screw. For this reason, we propose an efficient bag dust collector. Utility Model Content
