[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The frame 1 has a grinding chamber 101 and a dirt collecting chamber 103;

[0035] The cyclone mechanism 3 comprises an exhaust fan 301, a cyclone chamber 300 and a cyclone wheel 302. The cyclone chamber 300 is connected with the grinding chamber 101 through the air inlet 104. The cyclone chamber 300 is connected with the sewage collecting chamber 103 through the sewage outlet 311. The grinding chamber 101 is provided with a dust collecting frame 100 on one side of the air inlet 104. The exhaust fan 301 is arranged on the frame 1 to make the gas in the grinding chamber 101 flow into the cyclone chamber 300 from the air inlet 104. The cyclone wheel 302 is arranged in the cyclone chamber 300 to form a rotating airflow in the cyclone chamber 300.

[0036] The spray mechanism 4 comprises a cyclone spray pipe 401 and an upper spray pipe 402 . The cyclone spray pipe 401 extends into the cyclone chamber 300 for spraying water in the cyclone chamber 300 , and the upper spray pipe 402 extends into the grinding chamber 101 for spraying water in the grinding chamber 101 .

[0037] When the wet polishing, grinding and dust collecting machine with an explosion-proof vortex structure is used for grinding and dust removal, the steps are as follows: a worker performs grinding in the grinding chamber 101, and large particles of dust fall into the dust collecting frame 100 under the action of gravity, and part of the small particles of dust are mixed with the water sprinkled from the upper spray pipe 402 and enter the cyclone chamber 300 through the air inlet 104, and part of them directly enter the cyclone chamber 300 through the air inlet 104. After entering the cyclone chamber 300, the water-powder mixture flows into the sewage collecting chamber 103 through the sewage outlet 311. The dust that is not mixed with water enters the cyclone chamber 300 and mixes with the water sprinkled from the cyclone spray pipe 401, and rotates and rises under the drive of the cyclone wheel 302 to further mix with the water. The successfully mixed water-powder mixture descends under the action of gravity and is discharged from the sewage outlet 311 into the sewage collecting chamber 103.

The cyclone chamber 300 is partially directly entered into the cyclone chamber 300 through the air inlet 104. The water-powder mixture enters the cyclone chamber 300 and flows into the sewage collecting chamber 103 through the sewage outlet 311. The dust that is not mixed with water enters the cyclone chamber 300 and mixes with the water sprinkled from the cyclone spray pipe 401. The dust is further mixed with the water by rotating and rising driven by the cyclone wheel 302. The multi-stage combination of front-stage collection, middle-stage spraying and terminal cyclone mixing is used for dust removal, and the dust removal and recovery effect is good. The dust is efficiently mixed with water to improve the dust capture efficiency of the water system and reduce dust emissions.
