Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, in particular to a coal powder bag type dust collector with a self-cleaning function. Background Art

[0002] The coal powder bag dust collector is a dust removal equipment specially designed for handling coal powder and other dusts. It is based on bag filtration technology and pulse jet cleaning technology. It intercepts and captures coal dust particles in the air through filter bags, thereby achieving efficient dust removal effects. The core part of the coal powder bag dust collector is the bag, which is usually made of high-temperature resistant fiber material with a large surface area and good filtering performance. When the dust-laden gas passes through the bag, the coal dust particles are intercepted and deposited on the bag to form an ash layer, and the filtered clean gas is discharged through the fine pore structure of the bag.

[0003] A Chinese patent with publication number "CN217015862U" discloses a coal powder bag dust collector with high safety. The application includes a shell, a ash hopper is installed at the bottom end of the shell, a cleaning structure is arranged at the bottom of the ash hopper, and the cleaning structure includes a connecting rod, the connecting rod is fixedly connected to the surface of the ash hopper, the surface of the connecting rod is sleeved with a support plate, the surface of the support plate is fixedly connected with a support frame, the surface of the support frame is rotatably connected with a connecting frame, and the surface of the connecting frame is fixedly sleeved with a second gear.

[0004] However, this device still has some shortcomings. Because the dust itself is small and light, scraping off the dust with a scraper is feasible, but the effect is not good. The scraper can only scrape off thicker and larger dust accumulation, and a large amount of dust will still be adsorbed on the inner wall of the dust collector, thereby reducing the cleaning effect of the dust on the inner wall of the dust collector. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a coal powder bag dust collector with a self-cleaning function to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A coal powder bag dust collector with a self-cleaning function comprises a dust collector body, a dust outlet head is arranged at the bottom end of the dust collector body, a sleeve plate is fixedly connected to the bottom end of the dust outlet head, a movable plate is clamped at the bottom end of the sleeve plate, a water box is fixedly connected to the bottom end of the movable plate, the top end of the water box is symmetrical with the bottom end of the dust outlet head, a machine cover is arranged at the top end of the dust collector body, a water pump is arranged at the top end of the machine cover, a water suction pipe is arranged at the rear side of the water pump, the water suction pipe is communicated with the inner side of the water box, a collection box is fixedly connected to the bottom end of the machine cover, the outer wall of the collection box is in contact with the inner wall of the dust collector body, a water hole is arranged at the bottom end of the collection box, and the water hole is connected to the inner side of the collection box A water outlet pipe is installed on the front side of the water pump, and the water outlet pipe is connected to the interior of the collecting box. A protective plate is threadedly connected to the front side of the dust collector body. A proper amount of water is poured into the water box. When cleaning the inner wall of the dust collector body, the user can start the water pump, and its suction pipe can suck the water in the water box, and its water outlet pipe can discharge the water source into the collecting box. The water inside the collecting box can flow to the inner wall of the dust collector body through the water hole, so that the dust on the inner wall of the dust collector body can be washed away, and the water with dust will then flow back into the water box through the dust outlet head again, thereby effectively improving the cleaning effect of the dust on the inner wall of the dust collector body.

[0008] As an optimal technical solution, a card hole is opened on one side of the sleeve plate, and a spring card buckle matching the card hole is fixedly connected to one side of the movable plate, and the spring card buckle is carded to the inner side of the card hole, and the movable plate is carded to the bottom end of the sleeve plate through the card hole and the spring card buckle, and the inner wall of the water box is slidably connected to the limit frame, and the inner wall of the limit frame is fixedly connected with a filter plate, and the filter plate covers the inner side of the limit frame, and the top of the limit frame is fixedly connected with a connecting plate, and one side of the connecting plate is fixedly connected to the other side of the sleeve plate through the setting of the spring card buckle, and the height of the water box can be adjusted by inserting the spring card buckle into the card holes at different positions.

[0009] As a preferred technical solution, a slide groove matching the limit frame is opened on the inner wall of the water box, and the limit frame is slidably connected to the inner wall of the water box through the slide groove. By opening the slide groove, the position of the limit plate can be effectively limited, thereby preventing the limit plate from being displaced.

[0013] As a preferred technical solution, a power supply module is installed on the top of the machine cover, and a control module is installed on one side of the dust collector body. The power supply module is connected to the control module and the water pump circuit, and the control module is connected to the water pump electronic control. By installing the control module, the operation of the water pump can be effectively controlled.

[0016] Secondly, because the movable plate is clamped at the bottom of the sleeve plate, the height of the water box can be adjusted by inserting the spring clamp into the clamping holes at different positions through the setting of the spring clamp. Due to the existence of the connecting plate, when the water box is adjusted upward, the connecting plate will push the limit frame to the bottom of the inner side of the water box. When the water box is adjusted downward, the limit frame will be pushed to the top of the inner side of the water box.
