[0031] Reference Figure 1-5 The utility model provides a high-efficiency dust removal device for a smelting furnace: it includes a base 1, four moving wheels 23 are arranged at the bottom of the base 1, a collecting bucket 24 is arranged at one end of a fixed pipe 4, a water tank 2 is fixedly connected to the top of the base 1, a square pipe 3 is fixedly connected to the top of the water tank 2, a fixed pipe 4 is fixedly connected to the top of the square pipe 3, two annular sleeves 5 are arranged on the fixed pipe 4, the annular sleeve 5 is rotatably connected to the fixed pipe 4, the annular sleeve 5 and the fixed pipe 4 are sealed and rotatably connected, two connecting grooves 6 and two slots 7 are arranged on the fixed pipe 4, and the insides of the two slots 7 are rotatably connected to the cover plate 1 3, a suction fan 8 and a fixing plate 9 are fixedly installed inside the fixed tube 4, two connecting plates 10 are slidably connected to the fixing plate 9, cloth bags 11 are arranged on the two connecting plates 10, and a water spray assembly is arranged on the water tank 2. Through the coordinated use of the base 1, the square tube 3, the fixing tube 4, the annular sleeve 5, the connecting groove 6, the slot 7, the suction fan 8, the fixing plate 9 and the cover plate 13 and other structures, when the two annular sleeves 5 are rotated and one of the cloth bags 11 is replaced, the other cloth bag 11 can perform filtering work, and there is no need to stop the filtering work of the smoke of the device, thereby improving the filtering efficiency of the smoke.

[0032] Rubber blocks 12 are embedded in the two slots 7. Through the setting of the rubber blocks 12, after the cover plate 13 is closed, the connection between the cover plate 13 and the fixed pipe 4 can be sealed to prevent smoke from leaking from the connection between the cover plate 13 and the fixed pipe 4. A fixing block 14 is fixedly connected to the two cover plates 13. Two fixing blocks 2 15 are fixedly connected to the outer surface of the fixed pipe 4. Pins 16 are provided on the two fixing blocks 2 15. One end of the two pins 16 passes through the two fixing blocks 1 14 respectively.

[0033] A plurality of filter plates 17 are arranged on the square tube 3, and the plurality of filter plates 17 are arranged obliquely and movably connected to the square tube 3. Through the arrangement of the filter plates 17, the water sprayed from the atomizing nozzle 22 can be filtered, and the filter plates 17 can be directly pulled out when cleaning, so as to facilitate cleaning. A partition plate 18 is arranged inside the connecting groove 6, and the partition plate 18 is fixedly connected to the annular sleeve 5.

[0034] The water spray assembly includes a water pump 19 fixedly installed on the top of the water tank 2, and the water suction end of the water pump 19 extends to the bottom of the inner wall of the water tank 2 through a pipeline, and the output end of the water pump 19 is fixedly connected with a connecting pipe 20, and the other end of the connecting pipe 20 is fixedly connected with a connecting box 21, and the connecting box 21 is fixedly installed on the outer surface of the square tube 3. A plurality of atomizing nozzles 22 are arranged on the connecting box 21, and the other ends of the plurality of atomizing nozzles 22 all penetrate the square tube 3 and extend to the inside of the square tube 3. Part of the connecting pipe 20 surrounds the outer surface of the suction fan 8. When the suction fan 8 starts to work, under the action of the water pump 19, the clean water circulating in the connecting pipe 20 can flow through the outer surface of the suction fan 8, cool down the suction fan 8 during the working process, thereby improving the service life of the suction fan 8.

[0035] Working principle: When working, after the device is moved to a suitable position by the moving wheel 23, appropriate clean water is first added to the water tank 2, and then the water pump 19 is started. After the clean water in the water tank 2 is transported to the inside of the connecting box 21 through the connecting pipe 20, it is sprayed out by a plurality of atomizing nozzles 22. At this time, the suction fan 8 can work, and under the cooperation of the fixed pipe 4 and the collecting bucket 24, the smoke generated during smelting is absorbed, and one of the cloth bags 11 filters the dust in the absorbed smoke. Under the action of the suction fan 8, the filtered smoke is blown into the inside of the square tube 3 from the blowing end of the suction fan 8, and then it is filtered and adsorbed again by the water sprayed by the atomized spray, so as to improve the filtering effect of the smoke. At the same time, when the suction fan 8 is started to work, and under the action of the water pump 19, the clean water in the connecting pipe 20 can flow through the inside of the part of the connecting pipe 20 wrapped around the suction fan 8 during the circulation process, so that the suction fan 8 can be cooled during the working process, thereby increasing the service life of the suction fan 8.

[0036] When one of the cloth bags 11 needs to be replaced after being used for a long time, the two annular sleeves 5 are manually rotated to make the two partitions 18 rotate inside the two connecting grooves 6 respectively, so that the cloth bag 11 to be replaced is between the two partitions 18, while the other cloth bag 11 performs filtering work, and then the latch 16 on the corresponding cover plate 13 is manually removed, and after the cover plate 13 is released, the cover plate 13 is opened, and the connecting plate 10 can be directly manually moved to drive the cloth bag 11 to be replaced to move out from the inside of the fixing tube 4, and the cloth bag 11 can be replaced.
