[0002] A dust collector is a device used to separate dust from flue gas or other gases. Its function is to prevent industrial pollution and protect human health. Dust collectors are widely used in industries such as steel, chemical, cement, metallurgy, mining, ceramics, and food; however, most existing dust collectors usually have a relatively simple dust removal effect, usually only have a single filtering or dust removal function, so that the dust removal effect is low and the application range is narrow. At the same time, the internal dust removal structure is usually fixed on the device and cannot be quickly removed, so that during long-term use, dust and impurities accumulate in large quantities and cannot be effectively cleaned, which continuously reduces the filtering effect and shortens the service life, and cannot meet the use needs well.

[0020] A slide rod 10 is slidably connected inside the sleeve 9, and the bottom of the slide rod 10 moves downward and is inserted into the notch of the connecting groove 8. The slide rod 10 is located on the left side of the collecting box 4. When the slide rod 10 moves downward and is inserted into the notch, it will prevent the collecting box 4 from moving to the left, thereby fixing the position of the collecting box 4. A moving rod 11 is installed on the left side of the slide rod 10, and the slide rod 10 can be driven to move up and down by pulling the moving rod 11.

[0021] A movable frame 12 is arranged in the dust removal box 1, and the right side of the collecting box 4 is in close contact with the left side of the movable frame 12. The movable frame 12 is located on the left side of the filter plate 21. A filter plate 13 is inlaid and installed in the movable frame 12. The filter plate 13 can block the solid impurities entering the dust removal box 1, so that they fall and enter the collecting box 4. At the same time, the filter plate 13 will also filter the impurities in the air of the dust removal box 1, so that the larger impurities in the air cannot pass through the filter plate 13 and move to the right, and finally stay on the surface of the filter plate 13. The movable frame 12 extends upward and passes through the top box wall of the dust removal box 1. A handle 2 13 is installed on the top of the movable frame 12. By pulling the handle 2 13 upward, the movable frame 12 can be driven to move upward, and the movable frame 12 can be taken out of the dust removal box 1, so as to facilitate the cleaning of the filter plate 13. A fixing groove 14 is provided at the bottom of the dust removal box 1, and the bottom of the movable frame 12 is inserted into the fixing groove 14 to fix the movable frame 12 to prevent the movable frame 12 from shaking.

When the sprayer 16 is started, mist water droplets can be sprayed downward through the nozzle 17 to adsorb fine impurities in the air, which lose their falling and enter the water tank 18. An upwardly open water tank 18 is installed in the dust removal box 1. The water tank 18 is located below the sprayer 16. A drain valve 19 is installed in the bottom box wall of the water tank 18. A downwardly extending drain pipe 20 is installed on the bottom box wall of the dust removal box 1. The top of the drain pipe 20 is connected to the bottom of the drain valve 19. Opening the drain valve 19 will allow the water in the water tank 18 to pass through the drain valve 19 and flow out through the drain pipe 20.

[0023] A fan 24 is arranged on the right side of the dust removal box 1. A plurality of mounting frames 23 are installed on the right side of the dust removal box 1. The specific number of the mounting frames 23 is four. The end of the mounting frame 23 away from the dust removal box 1 is connected to the fan 24. A rotating shaft 25 is installed on the left side of the fan 24. The rotating shaft 25 extends to the left and passes through the air outlet 22. A plurality of fan blades 26 are installed on the surface of the rotating shaft 25. Starting the fan 24 to rotate the rotating shaft 25 will drive the fan blades 26 to rotate, so that external air and other substances enter the dust removal box 1 through the dust collection funnel 3 and the air inlet 2, and the air inside the dust removal box 1 flows to the right and finally flows out through the air outlet 22 to complete the gas circulation.

[0024] When in use, the staff can turn on the fan 24 and the sprayer 16 to allow the outside air and dust to enter the dust removal box 1 through the dust collection funnel 3 and the air inlet 2. The dust and larger impurities will be filtered and blocked by the filter plate 13, and fall into the collection box 4 and be collected by the collection box 4. Then the air and some fine impurities will pass through the filter plate 13, and the fine impurities will then be absorbed by the fine water droplets sprayed by the sprayer 16 through the nozzle 17, and then fall into the water tank 18. The remaining air will continue to move to the right and pass through the filter plate 21, so that the harmful gases in the air are absorbed and filtered by the filter plate 21, and then the dry Clean air will flow out of the dust removal box 1 through the air outlet 22; after use and closing all devices, when cleaning is required, the movable rod 11 can be pulled upward to make the slide rod 10 leave the slot of the fixed slot 8, and then the handle 1 7 can be pulled to the left to move the collection box 4 to the left and leave the dust removal box 1, and then the dust and impurities in the collection box 4 can be cleaned, and then the handle 2 15 can be pulled upward to remove the movable frame 12 from the dust removal box 1, and then the filter plate 1 13 can be cleaned, and then the drain valve 19 can be opened to allow the sewage in the water tank 18 to flow out through the drain pipe 20.
