[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to the drawings, including a polishing machine 1 and a dust removal box 2 arranged on one side, the dust removal box 2 is connected with the polishing position of the polishing machine 1 through a pipeline, and is driven by a gas pump, for absorbing the dust generated on the polishing position into the dust removal box;

[0024] Referring to Figure 2As shown, the grinder 1 includes a protective shell and a grinding wheel installed in the protective shell, one side of the grinding wheel is provided with a workbench 12, and the upper portion of the workbench is provided with a protective cover 3. In the implementation, an air suction port is arranged in the workbench 12 and the protective cover 3.

[0025] The dust removal box 2 is provided with a rotor 23, and the rotor 23 is provided with a mounting groove 21 on the side. A filter blade 25 is slidably connected in the mounting groove 21, and the filter blade 25 is provided with a plurality of filter blades.

[0026] The dust removal box is provided with an air inlet 22 and an air outlet 26, and a filter flow field is formed between the air inlet 22 and the air outlet 26. The rotor 23 is installed in the filter flow field, and the filter flow field includes a filter cavity and a flushing cavity. The filter cavity and the flushing cavity are arranged on the rotation path of the filter blade 25. Referring to Figure 1 As shown, the space formed between the air inlet 22 and the upper portion of the air outlet 26 is the filter cavity.

[0027] When the filter blade 25 rotates to the filter cavity, the filter blade 25 extends out of the mounting groove 21 and abuts against the cavity wall of the filter cavity.

[0028] When the filter blade 25 rotates to the flushing cavity, the mounting groove 21 is in butt joint with the flushing cavity 243, and the filter blade is flushed by injecting clean water.

[0029] The mounting structure of the filter blade 25 is shown in Figure 1 and Figure 3 As shown, a circular filter flow field is formed in the dust removal box 2, and the rotor 23 is concentrically connected to rotate in the dust removal box.

[0030] Continuing to refer to Figure 4 As shown, the inner wall end face of the dust removal box 2 is provided with a track groove 201, one side of the filter blade 25 is provided with a guide block, and the guide block is embedded in the track groove 201. The guide block can be in the form of a ball bearing. The track groove 201 guides the position of the filter blade 25 in the mounting groove 21 when the filter blade 25 rotates.

[0031] As shown in detail in Figure 1 As shown, the part of the track groove 201 in the filter cavity guides the filter blade 25 out of the mounting groove 21 and keeps the end of the filter blade 25 abutting against the wall of the filter cavity. The part of the track groove 20 in the flushing cavity guides the filter blade 25 into the mounting groove 21. As shown in the track groove 201, the upper portion is a circular arc, and the distance between the upper portion and the inner wall of the dust removal box 2 is the same. The filter blade 25 can be kept in close contact with the inner wall of the dust removal box 2 in the guide straight line, and the air suction of the filter blade 25 is filtered. At the bottom of the track groove 201, A corresponds to the flushing cavity, and at this time the filter blade 25 is retracted into the mounting groove 21.

[0032] Continuing to refer to Figure 1 The flushing cavity is surrounded by the inlay 24 at the bottom of the dust removal box 2.Figure 5 The middle part of the insert 24 is a flushing cavity 243, and the two sides are provided with a recovery bin 242. A cleaning wheel 241 is arranged at the entrance of the recovery bin 242, and the cleaning wheel 241 is used to clean the circumferential side of the rotor 23. In addition, it is worth mentioning that the two ends of the insert 24 are provided with sealing rollers which are rotatably connected to the insert 24. The sealing rollers keep the inside of the insert 24 sealed with the inside of the dust removal box 2 in a static state, but do not prevent the rotation of the rotor 23.

[0033] Continuing to refer to Figure 1 The center of the rotor 25 is provided with a hollow shaft 27 which can be used as a rotating shaft of the rotor 25. The hollow shaft 27 is in communication with the mounting groove 21. If the hollow shaft 27 is fixed, the hollow shaft 27 only needs to be provided with an opening, and each mounting groove 21 is provided with a corresponding hole. When the filter blade 25 in the mounting groove 21 rotates to the flushing cavity position, the hole of the mounting groove 21 is connected with the hole of the hollow shaft 27. At this time, clean water can be directly introduced into the hollow shaft 27 to flush the filter blade 25.

[0034] In work, the rotor 23 is given a power which is opposite to the direction of the wind speed. The wind sucked by the air pump enters from the air inlet 22 and is filtered by the filter blade 25. It is worth mentioning that under the action of centrifugal force, some heavy sand waste will stay on the surface of the rotor 23. Therefore, in the design, the surface of the rotor 23 can be increased in friction to retain such waste on the surface.

[0035] The filter blade 25 is slowly rotated under the driving of the rotor 23 and is guided by the track groove 201. One of the filter blades 25 enters the flushing cavity 243 position in the middle of the insert 24, clean water is introduced to clean the filter blade 25, and the water flushing method is used in the small space of the mounting groove. It is relatively efficient, and the filter blade 25 forms a structure similar to a wet curtain to improve the filtering effect and can cool the wind.

[0036] The sand waste cleaned by the cleaning wheel 241 is separately recovered and treated. The flushing cavity 243 is connected with a separation chamber below for treating the mixture of dust and water or directly discharging.

[0037] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made in the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
