A filter box adapted to the through hole is installed inside the circulating water tank. The filter box extends into the circulating water tank. A set of limiting grooves is symmetrically arranged on the wall between the two water pipes. A filter screen is inserted into the limiting groove. A water pump is installed on the side of the dust collection chamber. A water pump is fixedly connected to the bottom of the water pump. The water pump extends into the bottom of the circulating water tank. The water pump is connected to the two water pipes through a double-pipe. Suction pipes are fixedly connected to the side of the wall between the two water pipes. A hose is fixedly connected to the end of the suction pipe. A suction hood is fixedly connected to the other end of the hose. A drain pipe is fixedly connected to the side of the circulating water tank. A valve is fixedly connected to the drain pipe.

[0005] Preferably, three sets of limiting grooves are symmetrically provided on the wall above the top water guide pipe, and a filter screen is inserted into each limiting groove.

[0006] Preferably, the mesh size of the filter screen gradually decreases from bottom to top.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 4The dust removal device shown is for a lint-filled paper baling equipment. It includes a fixedly connected air intake chamber 1 and a dust settling chamber 2. A circulating water tank 3 is fixedly connected to the bottom of the dust settling chamber 2. An air intake fan 4 is installed inside the air intake chamber 1, and an air intake duct 5 is located at the bottom of the air intake fan 4, extending outside the air intake chamber 1. Under the action of the air intake fan 4, the gas containing paper dust is drawn in and discharged from the air intake chamber through the air intake duct 5. An air intake port 6 is located at the bottom of the air intake duct 5, extending into the dust settling chamber 2. Two U-shaped water guide pipes 7 are installed inside the dust settling chamber 2, with a support plate 8 at the bottom of each water guide pipe 7. Several atomizing nozzles are provided on the outer wall of each water guide pipe 7. The nozzle 9 and the bottom of the dust collection chamber 2 are fixedly connected to a water trough 10. A square through-hole is provided on the water trough 10, and a matching filter box 11 is inserted into the square through-hole. The filter box 11 extends into the circulating water tank 3. The atomizing nozzle 9 continuously atomizes and sprays the gas containing paper dust, causing the paper dust and water mist to mix and flow into the water trough 10. The filter box 11 filters the water mixed with paper dust, and the mixture finally flows into the circulating water tank 3. A set of limiting grooves 12 are symmetrically provided on the chamber wall between the two water guide pipes 7. A filter screen 13 is inserted into the limiting groove 12. The filter screen 13 between the two water guide pipes 7... The intake air is filtered to remove larger pieces of paper dust, which are then filtered below the filter. A filter screen 13 is inserted into a limiting groove 12, allowing for easy disassembly and cleaning by staff. A water pump 14 is located on the side of the dust collection chamber 2, with a water suction pipe 15 fixedly connected to its bottom. The water suction pipe 15 extends to the bottom of the circulating water tank 3. The water pump 14 is connected to two water guide pipes 7 via a double-ended pipe 16. Under the action of the water pump 14, water is continuously supplied to the water guide pipes 7 and sprayed out through atomizing nozzles 9 to treat the air containing paper dust. The chamber between the two water guide pipes 7... A suction pipe 17 is fixedly connected to the side of the wall, and a flexible hose 18 is fixedly connected to the end of the suction pipe 17. A suction hood 19 is fixedly connected to the other end of the flexible hose 18. The suction hoods 19 on both sides cover the feeding end and the packaging end of the packaging equipment, respectively, which can effectively suck up the paper scraps and dust generated during the packaging process. A drain pipe 20 is fixedly connected to the side of the circulating water tank 3, and a valve 21 is fixedly connected to the drain pipe 20. According to the water usage and dust usage in the circulating water tank 3, the water in the circulating water tank 3 is replaced regularly. When replacing, the water in the circulating water tank 3 can be drained through the drain pipe 20 and replaced with new circulating water.

[0022] To further improve the dust suppression and filtration effect, three sets of limiting grooves 12 are symmetrically arranged on the wall above the top water guide pipe 7. Each limiting groove 12 is fitted with a filter screen 13. The mesh size of the filter screen 13 gradually decreases from bottom to top. With the combined effect of the three layers of filter screens 13, the dust suppression effect of paper scraps and dust can be greatly improved, preventing paper scraps and dust from spreading in the working environment and effectively protecting the health of the staff.

[0023] To facilitate the cleaning of paper scraps and dust that settle in the circulating water tank 3, and to make it easier to add new circulating water, a cleaning port 22 is provided on the circulating water tank 3.

[0024] To facilitate staff to directly observe the dust suppression work inside the dust suppression chamber 2, an observation window 23 is fixedly connected to the rear wall of the dust suppression chamber 2.

[0025] To facilitate the disassembly and cleaning of filter box 11 and filter screen 13 by staff, and to facilitate the maintenance of induced draft fan 4, maintenance doors 24 are hinged on induced draft chamber 1 and dust settling chamber 2.

[0026] To reduce noise during operation of the air intake chamber 1, noise-reducing cotton 25 is pasted on the inner wall of the air intake chamber 1.

[0027] To ensure the airtightness of the dust collection chamber 2, a sealing rubber that matches the maintenance door 24 is fixedly connected to the door frame of the dust collection chamber 2.

[0028] In order to facilitate the adjustment of the air volume of the induced draft fan 4, an air valve 26 is fixedly connected at the connection between the suction pipe 17 and the hose 18.

[0029] To facilitate heat dissipation during the operation of the induced draft fan 4, several heat dissipation holes 27 are provided on the top of the induced draft chamber 1.

[0030] The working process of this utility model is as follows: First, since the paper dust generated by the lint-filled paper baling equipment is mainly generated at the feeding end and the baling end, the exhaust hood 19 is placed over the feeding end and the baling end of the equipment to extract and suppress the paper dust generated during the operation of the lint-filled paper baling equipment. Second, the exhaust fan 4 and the water pump 14 are turned on. Under the action of the exhaust fan 4, the air carrying paper dust is drawn into the dust suppression chamber 2 through the hose 18 and the suction pipe 17. Under the action of the water pump 14, the circulating water in the circulating water storage tank 3 is extracted through the water extraction pipe 15 and supplied to the water guide pipe 7. Under the action of the atomizing nozzle 9, the extracted air carrying paper dust is continuously atomized and sprayed to suppress the dust. After the paper dust and atomized water vapor are mixed, they fall into the water dropper 10. The filter box 11 in the water dropper 10 filters the water mixed with paper dust and finally flows into the circulating water storage tank 3. Paper scraps and dust are filtered into the filter box 11. Furthermore, the four layers of filters 13 with different mesh sizes effectively filter out paper scraps and dust, preventing them from being discharged through the air duct 5. This ensures that the discharged air is free of paper scraps or dust. Simultaneously, the filters 13 are inserted into the limiting groove 12, facilitating easy disassembly and cleaning by staff. The installation and disassembly process is very convenient, effectively reducing the workload of staff. Finally, the air that has undergone dust suppression and filtration is discharged from the air duct 5 into the air chamber 1. Based on the water usage and dust levels in the circulating water tank 3, the water in the circulating water tank 3 is periodically replaced. Staff can drain the water through the drain pipe 20, clean out the small amount of paper scraps and impurities deposited at the bottom of the circulating water tank 3 through the cleaning port 22, and add new circulating water to the circulating water tank 3 through the cleaning port 22.

[0031] The above description is only a preferred embodiment of the present utility model. The technical solution of the present utility model is not limited thereto. It should be noted that for those skilled in the art, under the technical teachings provided by the present utility model and as common knowledge in the field, other equivalent modifications and improvements can be made, which should also be considered within the protection scope of the present utility model.
