[0032] Reference Figures 1 to 4 , the polymer dust collection and treatment device of the first embodiment of the present invention includes a box body 100, a negative pressure air duct 200, a negative pressure fan 300, a dust filter cartridge 400, a dust collecting box 500, a spray device 600 and a dust collecting pipe 700; the box body 100 is provided with a dust removal chamber 110, and a negative pressure hole is penetrated through the upper end of the box body 100, and a switch door is provided on the front side of the box body 100, and the switch door closes the dust removal chamber 110; the negative pressure air duct 200 is connected to the negative pressure hole and communicates with the dust removal chamber 110; the negative pressure fan 300 is built in the negative pressure hole and is arranged between the dust removal chamber 110 and the negative pressure air duct 200; the dust filter cartridge 400 is arranged below the negative pressure hole, the lower end of the dust filter cartridge 400 is closed and the upper end is open; the dust collecting box 500 is built in the dust removal chamber 110, and the dust collecting box 500 is embedded in the lower part of the dust removal chamber 110 and is located at the dust filter cartridge 400, a dust filter 510 is horizontally arranged inside the dust box 500, and the dust filter 510 covers the middle part of the dust box 500; the spray device 600 is arranged on both sides of the dust filter cartridge (400), and the spray device 600 includes a spray pipe 610 and a spray head 620, the spray pipe 610 is horizontally arranged above the dust removal chamber 110, the spray pipe 610 is connected to an external water source, and the spray head 620 is fixed on the spray pipe 610, and multiple spray heads 620 are divided into multiple groups, and multiple groups of spray heads 620 are arranged at intervals along the axial direction of the spray pipe 610. On the cross section of the spray pipe 610, in a single group of spray heads 620, at least two spray heads 620 are arranged obliquely downward toward opposite sides respectively; one end of the dust collecting pipe 700 extends into the dust collecting box 500 and is located below the dust filter 510, and the other end is connected to the external environment.

[0033] The switch door of the box body 100 can be opened or closed to make the dust removal chamber 110 in an open or closed state. During actual use, it is necessary to put a dust box 500 into the dust removal chamber 110 to collect dust. Specifically, by turning on the negative pressure fan 300 and cooperating with the negative pressure air duct 200, the dust removal chamber 110 in the closed state is in a negative pressure state. At this time, the external environment is at a high pressure relative to the dust removal chamber (110), which causes the dust in the external environment to enter the dust box 500 through the dust collecting pipe 700, and the air entering the dust box 500 will be in a negative pressure state in turn. It passes through the dust filter 510 and the dust filter cartridge 400, and is finally discharged from the negative pressure air duct 200 above the dust filter cartridge 400. It should be emphasized that in the process of dust-laden air flowing, it will be subjected to secondary filtration by the dust filter 510 and the dust filter cartridge 400. At the same time, the spray device 600 located above will continue to spray water mist so that the dust can be adsorbed. Finally, a large amount of dust will be mixed into the water mist and stored in the dust box 500. When the water level in the dust box 500 reaches a certain level, the dust box 500 is directly taken out and put into another empty dust box 500.

[0034] In summary, under negative pressure, external dust will be collected into the dust removal chamber 110. With the help of high-pressure water for adsorption and two-stage filtration, most of the dust can be kept in the dust box 500 for centralized treatment, thereby improving the purification effect.

[0035] In some embodiments, in order to make the sprayed water better combine with the dust in the air, the spray pipe 610 is connected to a high-pressure water source, so that the impact force of the sprayed water mist is enhanced, the coverage area is correspondingly expanded, and it can better combine with the dust in the space.

In this embodiment, the partition 120 is used to divide the internal space of the box 100 into two relatively small dust removal chambers 110, and the dust in a single dust removal chamber 110 will be processed separately, effectively improving the dust removal efficiency.

[0037] In the above-mentioned second embodiment, in order to facilitate dust removal at any position, the dust collecting pipe 700 includes a fixed pipe 710 and a disassembly pipe 720, the fixed pipe 710 runs through the box 100 and is built into the dust removal chamber 110, and the disassembly pipe 720 and the fixed pipe 710 are detachably connected. It is convenient to assemble the dust collecting pipe 700 anywhere, and specifically, the two dust collecting pipes 700 are connected to the same exhaust pipe 730, wherein the two ends of the disassembly pipe 720 are detachably connected to the fixed pipe 710 and the exhaust pipe 730 respectively. Specifically, the exhaust pipe 730 has an air inlet and two air outlets, and the two air outlets are respectively connected to the two disassembly pipes 720, wherein the disassembly pipe 720 and the air outlet can be connected by a threaded manner, and similarly, the disassembly pipe 720 and the fixed pipe 710 can also be connected by a threaded manner, and the threaded connection method can improve the tightness while also improving the air tightness.

[0038] In actual work, in order to further improve the filtering effect, the negative pressure air duct 200 is built with a negative pressure filter 210 , and the negative pressure filter 210 is located above the negative pressure fan 300 .
