Description

Technical Field

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

[0002] A bag dust collector is a dry dust filtering device that uses bags to capture fine, dry, non-fibrous dust. The bags are made of textile filter cloth or non-textile felt, and use the filtering effect of fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag dust collector, the large particles and high specific gravity of the dust settle due to gravity and fall into the ash hopper.

[0003] A Chinese patent provides an ash hopper for a bag dust collector, with publication number CN219290880U, comprising an ash hopper body, a control valve fixedly sleeved on the bottom of the inner cavity of the ash hopper body, an electrostatic plate fixedly sleeved on the lower part of the interior of the ash hopper body, an annular tube located above the electrostatic plate fixedly sleeved on the outside of the ash hopper body, a connecting tube fixedly connected to the bottom of the annular tube, the other end of the connecting tube extending to the interior of the ash hopper body, a fixed plate located below the annular tube at the right end of the ash hopper body, and a fan fixedly installed on the top of the fixed plate.

[0004] The above-mentioned device has the ability to absorb external gas through the air inlet pipe, and then spray it out from the connecting pipe through the exhaust pipe and the annular pipe in turn, thereby blowing away the dust attached to the electrostatic plate, making it easier to discharge the dust. However, it is difficult to clean the dust adhering to the inside of the ash hopper by using a single fan to blow air and discharge dust. Some dust with strong adsorption force is still adsorbed inside the ash hopper. At the same time, there are many impurities mixed in the dust. Long-term adhesion will corrode the inside of the ash hopper, making it easy to make the inside rough, affecting the subsequent discharge of dust. Utility Model Content

At the same time, by flushing, impurities containing corrosive substances are cleaned, and corrosion of the inner walls of the fixed ash hopper body 1 and the movable ash hopper body 2 is avoided, and the smoothness of the inner walls is avoided. After flushing, air spray drying can be performed again, so that the inner walls of the fixed ash hopper body 1 and the movable ash hopper body 2 are in a relatively dry and clean state, further improving corrosion resistance.

[0026] Example 2

[0027] See Figure 2 and Figure 4, and on the basis of Example 1, it is further obtained that a mounting plate 4 is fixedly installed at the lower position of the inner wall of the fixed ash hopper body 1, and a dust removal motor 5 is fixedly installed at the bottom end of the mounting plate 4, and the top end of the drive shaft of the dust removal motor 5 is fixedly connected to a mounting block, and the top end of the mounting block is fixedly connected to a connecting plate 6 by fixing bolts at both sides.

[0028] Specifically, the driving shaft of the dust removal motor 5 drives the rotating plate 7 to rotate in the fixed ash hopper body 1 and the movable ash hopper body 2, which can drive the anti-adhesion scraper 9 installed on the rotating plate 7 to rotate in the movable ash hopper body 2 and the fixed ash hopper body 1, thereby scraping off the adhered dust, and the anti-adhesion scraper 9 is cleaned by blowing air or spraying water to further improve the dust removal effect.
