The bottom of the legs 13 is connected to the cart 1, and the top is connected to the dust suction tank 301. When the waste bucket 302 is installed on the dust suction tank 301, there is a gap between the dust suction tank 301 and the cart 1, which provides convenience when the waste bucket 302 is disassembled.

[0071] Please refer to Figures 7-9 , when performing the adsorption work, when the waste dust enters the dust suction tank 301, the first-step filtering effect is carried out through the filter element 303 provided inside; among them, large-particle material waste residues will be intercepted by the filter element 303 when passing through the filter element 303, and thus will fall into the waste bucket 302 along the trend;

[0072] The waste bucket 302 includes a housing 312 and an inner filter frame 322, where the inner filter frame 322 is designed as a wire mesh;

[0073] During use, half of the clear water needs to be connected into the housing 312, and then the inner filter frame 322 is placed into the housing 312, and the clear water will enter the inner filter frame 322; the added clear water helps to reduce the suspension concentration of dust and reduce the explosion risk; by adding water, the dust flying situation can be controlled, so that the dust is not easy to form an explosive concentration in the air. In addition, water can also reduce the temperature of the dust, thereby reducing the possibility of ignition.

[0074] Subsequently, when the large waste materials intercepted by the filter element 303 enter the waste bucket 302, they fall into the inner filter frame 322 and come into contact with the water in the housing 312 and dissolve together; after the housing 312 is disassembled from the dust suction tank 301 through the buckle, the inner filter frame 322 can be taken out, so that the large-particle waste residues dissolved in the water are taken up with the inner filter frame 322, and the waste residues are recycled.

[0075] After the waste residues are processed, the housing 312 and the inner filter frame 322 are cleaned, and clear water is connected into the housing 312 again, and it is connected to the bottom of the dust suction tank 301 for reuse.

[0076] Furthermore, the filter element 303 located inside the dust suction tank 301 can be disassembled by removing the cover 11, so that the filter element 303 can be replaced with a new one over a long period of use.

[0077] In the present utility model, the working steps of the device are as follows:

[0078] 1. First, connect the pipelines between the devices. When in use, take the overall grinding assembly 2 and place it at the position where grinding is required, and start the grinding machine 201 to grind the material through operation;

[0079] 2. Secondly, during grinding, open the switch valve 10 on the transfer pipeline 402 connected to the taken grinding assembly 2, so as to introduce pressurized air into the dust-proof cover 202 of the grinding assembly 2;

[0080] 3. Secondly, connect the connecting pipe 12 on the dust suction tank 301 to the vacuum cleaner of the on-site equipment. The upper side of the dust suction tank 301 is connected to the dust-proof cover 202 through a pipe to handle the waste particles in the dust-proof cover 202 during grinding;

[0081] 4. Finally, in the dust collection process, the air source is discharged from the connecting pipe 12 after passing through the filter element 303 first. Large-particle waste is filtered out and falls into the waste bucket 302. Subsequently, the waste bucket 302 is taken out of the dust suction tank 301, and the inner filter frame 322 is taken out to further recycle the large-particle waste received.

[0082] The foregoing has shown and described the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments.
