Description

Technical Field

[0001] The utility model relates to the technical field of calcium hydroxide production, in particular to a pulse bag dust collector for calcium hydroxide production. Background Art

[0002] Calcium hydroxide is a strong alkali with bactericidal and antiseptic properties. It is corrosive to skin and fabrics. Calcium hydroxide is used to make bleaching powder, hard water softeners, disinfectants and insecticides, depilatories for leather making, sugar refining and building materials. During the production process of calcium hydroxide, a dust collector is required to deal with dust in the air.

[0003] After searching, the existing patent publication number CN214050817U is a pulse bag dust collector for calcium hydroxide production, which can effectively fix the dust bags to prevent the dust bags from being washed away when dusty gas is introduced. The gas after water washing can drive the fan blades to rotate when passing through the ventilation pipe. The rotation of the fan blades can drive the striking rod to rotate. The rotating striking rod will hit the dust bags, thereby preventing dust from clogging the air outlet of the dust bags, thereby ensuring dust removal efficiency, and there is no need to set up other power sources to avoid clogging the dust bags, which can effectively reduce production costs.

[0004] However, the above patent still has certain defects. The air is dusted only by a dust bag. Although it is prevented from being blocked by knocking, the dust bag still needs to be replaced frequently to ensure the filtering effect. The continuity of dust removal cannot be guaranteed during the replacement process. The machine needs to stop working and be restarted for dust removal after replacement, which seriously affects the dust removal efficiency of calcium hydroxide production. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a pulse bag dust collector for calcium hydroxide production. By setting two dust bags, when the filtering effect of one dust bag decreases, the filtering structure can be quickly replaced by rotating adjustment of the structure to ensure the continuity of the dust removal structure without stopping the machine.

[0006] The cam is fixedly provided with a top cover on the top of the casing, and a bottom cover is installed on the top cover of the casing, and a circular hole is formed on one side of the outer wall of the casing, and a sliding groove is formed on the inner wall of the sliding groove, and a rotary disk is slidably connected to the rotary disk. The rotary disk has a threaded hole on one side of the outer wall, and a sleeve is connected to the inner wall of the threaded hole through a threaded hole. The inner wall of the sleeve is fixedly connected to the dust bag on the other side of the inner wall of the casing. The outer wall of the partition is provided with a rectangular groove on one side of the partition, and the outer wall of the other side of the rotary disk is fixedly connected to the movable plate. The outer wall of the other side of the movable plate is equipped with a rotating shaft, and the rotating shaft is slidably connected to the inner wall of the rectangular groove. The top inner wall of the box body is provided with a vertical pipe second, and the top outer wall of the box body is provided with a vertical pipe first. The top outer wall of the vertical pipe one is slidably connected to the annular plate, and the four corners of the outer wall of the annular plate are fixedly connected

[0007] In some embodiments, the four corners of the inner wall of the annular plate are fixedly connected with fixed rods, and the inner walls of the fixed rods are fixedly connected with movable rods.

[0008] In some embodiments, a slide rail is provided on the outer wall of the bottom end of the vertical pipe 2, the annular plate is slidably connected to the inner wall of the slide rail, and the knocking rod is adapted to the size of the dust bag.

[0009] In some embodiments, fan blades are fixedly connected to the top outer wall of the movable rod, and the fan blades are distributed in a circular array and are adapted to the size of the vertical pipe 2.

[0010] In some embodiments, a limiting hole is provided on one side outer wall of the top of the second box body, and a locking knob is connected to the inner wall of the limiting hole through a thread.

[0011] In some embodiments, the outer walls of the other sides of the box body 1 and the box body 2 are both provided with dust removal ducts, and the outer wall of one side of the box body 1 is provided with a drain pipe.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First, the utility model is provided with a box body one, a box body two, a turntable, a dust bag, a partition and a movable plate, and the continuity of dust removal is ensured without pausing in the middle. The partition cooperates with the movable plate to rotate to divide the space of the box body two into two parts. The bottom space is specifically used for dust removal, and the top space is used for replacing the dust bag. By providing two dust bags, when the filtering effect of one dust bag decreases, the filtering structure can be quickly replaced by rotating the structure to ensure the continuity of the dust removal structure without stopping the machine, thereby improving the dust removal efficiency of calcium hydroxide production.

[0014] Secondly, the utility model is provided with a standpipe 1, a standpipe 2, an annular plate, fan blades and a locking knob. The purified air outputted from the standpipe 1 drives the movable rod to rotate through the fan blades, thereby driving the annular plate and four knocking rods to rotate and continuously knock the dust bag at the bottom to effectively prevent blockage, and the knocking effect is better. The locking knob provided on the box body 2 can limit the position of the turntable after adjustment to improve the structural stability.

[0015] The invention solves the problem of removing dust from the air by only one dust bag. Although the bag is knocked to prevent blockage, the bag still needs to be replaced frequently to ensure the filtering effect. The continuity of dust removal cannot be guaranteed during the replacement process. The machine needs to be stopped and replaced before it can be started again for dust removal.
