A vertical pipe is provided at the bottom of the filter cylinder, and cleaning brushes are symmetrically provided on both sides. An air guide pipe is connected to the bottom of the vertical pipe through a rotary joint. A drain pipe and a dust discharge pipe are respectively provided at the bottom of the dust settling chamber and the filter chamber.

[0006] A purification box is provided on one side of the dust removal box. The bottom of the purification box is provided with an input pipe and the top with an output pipe. An activated carbon adsorption layer is provided inside. One end of the air guide pipe passes through the side wall of the dust removal box and is connected to the input pipe.

[0007] Furthermore, a water supply pipe is provided on the top of the dust removal box above the dust settling chamber, and multiple nozzles are provided at the bottom of the spray pipe, with the top connected to the water supply pipe through a connecting pipe.

[0008] Furthermore, a vertical plate is installed at the top of the dust collection chamber between the partition and the spray pipe, and a baffle is installed on the side of the partition and the vertical plate facing each other.

[0009] Furthermore, at least two baffles are provided, which are inclined and staggered.

[0010] Furthermore, the top of the filter cartridge is provided with a mounting base, and multiple positioning blocks are installed on the top of the dust collection box. The inner side of the positioning block is provided with a groove, and the mounting base is rotatably installed in the groove.

[0011] Furthermore, a motor is installed on the top of the dust collection box above the filter chamber, and the output shaft of the motor is connected to the mounting base.

[0012] Furthermore, the cleaning brush is mounted on the inner wall of the filter chamber via a positioning rod.

[0013] Furthermore, a desiccant layer is provided inside the purification box below the activated carbon adsorption layer.

[0014] The advantages of this invention compared to existing technologies are as follows: By setting up a dust collection box, dust and exhaust gas first enter the dust collection box, and dust is effectively removed through spraying and filtration.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, a dust and exhaust gas treatment device for a furniture production workshop includes a dust collection box 1. One end of the dust collection box 1 is provided with an air inlet pipe 2. The dust collection box 1 is provided with a partition 3 inside. The upper part of the partition 3 is provided with a through groove, and the partition 3 divides the dust collection box 1 into a dust settling chamber and a filter chamber. The bottom of the dust settling chamber and the filter chamber are respectively provided with a drain pipe 9 and a dust discharge pipe 10.

[0022] Solenoid valves are installed on both the drain pipe 9 and the dust discharge pipe 10, and collection cylinders are connected to the bottom of both to collect impurities.

[0023] Multiple spray pipes 4 are installed on the top of the dust suppression chamber. A water supply pipe 15 is provided on the top of the dust removal box 1 above the dust suppression chamber. Multiple nozzles are provided at the bottom of the spray pipes 4 and the top is connected to the water supply pipe 15 through a connecting pipe. A vertical plate 16 is installed on the top of the dust suppression chamber between the partition 3 and the spray pipes 4. A baffle 17 is installed on the side of the partition 3 and the vertical plate 16 facing each other. The baffle 17 is inclined and staggered.

[0024] Water supply pipe 15 is connected to water pump, and water is delivered to water supply pipe 15 through water pump. After being atomized by nozzle, it can achieve dust suppression. The dust falls to the bottom of the dust suppression chamber with water mist and flows into the collection cylinder under the action of drain pipe 9. The baffle 17 can block water mist and dust. When water mist and dust collide with baffle 17, they will adhere to baffle 17 and gradually flow downwards, eventually flowing into the collection cylinder.

[0025] A filter cylinder 5 is rotatably installed inside the filter chamber. The bottom of the filter cylinder 5 is provided with a vertical pipe 6, and cleaning brushes 7 are symmetrically provided on both sides. The bottom of the vertical pipe 6 is connected to an air guide pipe 8 through a rotary joint. The top of the filter cylinder 5 is provided with a mounting base 18. Multiple positioning blocks 19 are installed at the top inside the dust collection box 1. The inner side of the positioning block 19 has a groove. The mounting base 18 is rotatably installed in the groove. A motor 20 is installed on the top of the dust collection box 1 above the filter chamber. The output shaft of the motor 20 is connected to the mounting base 18. The cleaning brushes 7 are installed on the inner wall of the filter chamber through a positioning rod 21.

[0026] The filter cartridge 5 can filter the dust again. When the motor 20 is turned on, the motor 20 drives the filter cartridge 5 to rotate through the mounting base 18. Under the action of the cleaning brush 7, the surface of the filter cartridge 5 can be cleaned.

[0027] The dust collector 1 has a purification box 11 on one side. The purification box 11 has an input pipe 12 at the bottom and an output pipe 13 at the top. It has an activated carbon adsorption layer 14 inside. One end of the air guide pipe 8 passes through the side wall of the dust collector 1 and is connected to the input pipe 12. A desiccant layer 22 is provided inside the purification box 11 below the activated carbon adsorption layer 14.

[0028] After the gas enters the purification chamber 11, it is first dried by the desiccant layer 22, and then the activated carbon adsorption layer 14 adsorbs the harmful gas.

[0029] In practical use, this device is controlled by an external PLC controller. The output pipe 13 of the purification box 11 is connected to an exhaust fan or vacuum pump, and the air inlet pipe 2 of the dust removal box 1 is connected to the gas collection hood set above the cutting and grinding station and the painting station. This allows dust and exhaust gas to enter the dust removal box 1 first. The dust is effectively removed through spraying and filtration, and the exhaust gas is purified through the activated carbon adsorption layer 14.
