Description

Technical Field

[0001] This utility model relates to the field of industrial calcium carbonate production technology, specifically to a dust removal device for industrial calcium carbonate production. Background Technology

[0002] In the process of manufacturing calcium carbonate, minerals such as limestone or marble need to be mechanically crushed and ground into dry or wet powder, which is then used in many fields such as papermaking, plastics, rubber, ink, chemical building materials, sealing materials, daily chemicals, food, and pharmaceuticals.

[0003] When a crusher breaks down minerals, it causes the minerals to fragment and generates mineral dust. This dust disperses widely, causing environmental pollution. Furthermore, since the mineral dust contains the same substances as the minerals, its widespread dispersal leads to a waste of mineral resources. Although dust suppression is typically achieved through spraying in production sites, the falling mineral dust mixes with other substances on the ground, making it difficult to collect and reuse. Therefore, there is an urgent need for a dust removal device for industrial calcium carbonate production. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for industrial calcium carbonate production, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dust removal device for industrial calcium carbonate production, including a box body, a sealing cover installed on the front of the box body by bolts, a suction fan connected to the right side of the box body, a filter screen plate installed inside the box body by bolts, a main pipe installed on the top of the box body by bolts, a corrugated hose fixedly connected to the end of the main pipe away from the box body, and a suction hood fixedly connected to the end of the corrugated hose away from the main pipe;

[0006] Two limiting rods are fixedly connected to the inner left wall of the box. Each limiting rod has a limiting block fixedly connected to its surface and a spring sleeved on its surface. The same striking plate is slidably sleeved on the outer side of the two limiting rods. An L-shaped bracket is fixedly connected to the left side of the striking plate. A motor is fixedly connected to the top of the box. A rotating shaft is fixedly connected to the output end of the motor. The bottom of the rotating shaft moves through the box and extends into its interior. A striking wheel is fixedly connected to the bottom of the rotating shaft.

[0007] Preferably, the left side of each spring is fixedly connected to a limiting block, and the right side of each spring is fixedly connected to a striking plate.

[0008] Preferably, the surface of the striking wheel abuts against the L-shaped bracket, and a sealing strip is provided on the outer side of the filter screen.

[0009] Preferably, a support frame is fixedly connected to the top of the box body, a sliding groove is provided on one side of the support frame, and a top groove communicating with the sliding groove is provided on the top of the support frame.

[0010] Preferably, a U-shaped frame is slidably disposed in the groove, and a threaded hole is provided on the top of the U-shaped frame, and a screw is threadedly connected in the threaded hole.

[0011] Preferably, a rotating cap is fixedly connected to the top of the screw, and the screw is slidably disposed in the top groove.

[0012] Preferably, the bottom of the U-shaped frame is fixedly connected to the suction hood.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] Firstly, this utility model involves starting a suction fan, which draws in dust particles through the suction hood. These particles then enter the housing via a corrugated hose and main pipe. The dust particles in the airflow are filtered by a filter screen inside the housing, achieving dust removal. A motor drives a rotating shaft to rotate, causing the protrusions of a striking wheel to strike an L-shaped bracket. This L-shaped bracket, in turn, causes the striking plate to slide back and forth on a limit rod under the action of a spring. As the striking plate slides back and forth, it strikes the filter screen, causing the dust particles on the filter screen to fall off and be stored inside the housing, preventing clogging and ensuring dust removal. The filter screen is bolted into the housing for easy maintenance and disassembly. Each of the four outer surfaces of the filter screen has a sealing strip, ensuring a seal between the filter screen, the housing, and the sealing cover after installation. The sealing cover, also bolted in, is easily removed for cleaning the dust stored inside the housing.

[0015] Secondly, in this utility model, by rotating the rotating cap on the screw, the fastening of the U-shaped frame can be released, and then the U-shaped frame can be pulled to slide in the slide groove. The bottom of the U-shaped frame is fixedly connected to the suction hood, so that the suction hood moves with it, thereby adjusting the suction hood and expanding the dust collection range.

[0028] Through the above technical solution, when removing dust for industrial calcium carbonate production, the suction fan 3 is started, and the dust particles generated are sucked in through the suction hood 7. They enter the housing 1 through the corrugated hose 6 and the main pipe 5, and are filtered by the filter screen 4 inside the housing 1 to achieve dust removal. The motor 13 drives the rotating shaft 14 to rotate, so that the protrusion of the striking wheel 15 strikes the L-shaped bracket 12. The L-shaped bracket 12 drives the striking plate 11 to slide back and forth on the limit rod 8 under the action of the spring 10. When the striking plate 11 slides back and forth, it strikes the filter screen 4, causing the dust particles on the filter screen 4 to fall off and be stored in the housing 1, preventing the filter screen 4 from clogging and affecting dust removal. The filter screen 4 is installed in the housing 1 with bolts for easy maintenance and disassembly. Each of the four outer surfaces of the filter screen 4 is provided with a sealing strip to ensure a seal between the filter screen 4 and the housing 1 and the sealing cover 2 after installation. The sealing cover 2 is installed with bolts for easy removal and cleaning of the inside of the housing 1.
