[0048] Figure 5 As shown, it includes a device body 1, which includes: a dust collector 12 is arranged on one side of a box body 11; a filter plate 13 is arranged inside the box body 11; an exhaust fan 14 runs through the outer wall of the box body 11; a scraper assembly 2 is arranged on the box body 11, and the scraper assembly 2 includes: a support frame 21 is arranged on the top of the box body 11; a motor 22 is arranged on the top of the support frame 21; a first threaded rod 221 is arranged at the output end of the motor 22 and runs through the top of the box body 11; a second threaded sleeve 222 is sleeved on the outside of the first threaded rod 221; a scraper 23 is arranged on the outside of the second threaded sleeve 222; a collecting bucket 24 is arranged on one side of the filter plate 13 and is located below the first threaded rod 221.

[0049] With the above structure, the silicon powder dispersed in the air is sucked into the box body 11 through the dust collecting member 12, and then

[0050] The filter plate 13 filters silicon powder in the air, and the filtered silicon powder will naturally fall into the collecting bucket 24. The filtered air is discharged from the box body 11 through the exhaust fan 14. When too much silicon powder remains attached to one side of the filter plate 13, the motor 22 is started through an external power supply. The output end of the motor 22 drives the first threaded rod 221 to rotate. The rotating first threaded rod 221 drives the scraper 23 to move up and down on one side of the filter plate 13 through the second threaded sleeve 222, and the silicon powder remaining attached to one side of the filter plate 13 is scraped into the collecting bucket 24, so as to avoid too much silicon powder remaining attached to one side of the filter plate 13 and improve the recovery efficiency of the silicon powder.

[0051] In a more specific embodiment, a gear 25 is disposed on the outer side of the first threaded rod 221.

[0052] Located inside the support frame 21, a second threaded rod 26 is arranged on the gear 25, a second threaded sleeve 261 is arranged on the outer side of the second threaded rod 26, a brush 27 is arranged on the outer side of the second threaded sleeve 261, and the second threaded rod 26 is meshedly connected with the first threaded rod 221 through the gear 25, so that the first threaded rod 221 drives the second threaded rod 26 to rotate through the gear 25, and the rotating second threaded rod 26 drives the brush 27 to move up and down on the other side of the filter plate 13 through the second threaded sleeve 261, so that the brush 27 sweeps away the silicon powder blocked in the filter holes on the filter plate 13, so as to avoid the filter holes on the filter plate 13 being blocked by silicon powder, thereby causing the filtered air to be unable to be discharged out of the box 11 through the exhaust fan 14.

[0053] In a more specific embodiment, the connection between the brush 27 and the second threaded sleeve 261 is provided.

[0054] The Velcro 29 allows the brush 27 to be bonded and connected to the second threaded sleeve 261 , thereby increasing the convenience of removing the silicon powder remaining on the brush 27 .

[0055] In a more specific embodiment, a sleeve 281 is provided at one end of the scraper 23 and the brush 27.

[0056] The box body 11 is provided with a slide rod 28 cooperating with the slide sleeve 281, so that the scraper 23 and the brush 27 are slidably connected with the slide rod 28, supporting the scraper 23 and the brush 27, and increasing the stability of the scraper 23 and the brush 27 moving up and down on both sides of the filter plate 13.

[0058] In a more specific embodiment, a slide plate 241 is provided at the bottom of the collecting bucket 24, and a slide groove 242 cooperating with the slide plate 241 is provided at the inner bottom of the box body 11. When the silicon powder in the collecting bucket 24 is fully recovered, the collecting bucket 24 is pulled out from the slide groove 242 at the inner bottom of the box body 11 through the slide plate 241.

[0059] In a more specific embodiment, the dust collecting part 12 includes: an air pump 121 disposed on one side of the box body 11; an air intake port 122 disposed on one side of the air pump 121 and penetrating the outer wall of the box body 11; an air exhaust port 123 disposed on the other side of the air pump 121. The air pump 121 is started by an external power supply, and the silicon powder dispersed in the air is sucked into the box body 11 through the air intake port 122 and the air exhaust port 123, and blown toward the filter plate 13.

[0060] Specifically, the model of the air pump 121 is QE-70. Its working principle is to use a mechanical device to make the diaphragm inside the pump do reciprocating motion, thereby compressing and stretching the air in the fixed volume of the pump chamber to form a vacuum (negative pressure), and generating a pressure difference between the pump suction port and the external atmospheric pressure. Under the action of the pressure difference, the gas is pressed (sucked) into the pump chamber and then discharged from the exhaust port. The principle structure is not drawn in the attached figure.

[0061] In a more specific embodiment, a second connecting plate 141 is provided on the outer side of the exhaust fan 14, and the exhaust fan 14 is threadedly connected to the box body 11 through bolts.

[0062] From the above description, it can be seen that the usage of the embodiment of the utility model is:

[0063] The silicon powder dispersed in the air is sucked into the box body 11 through the dust collecting piece 12, and the silicon powder in the air is filtered through the filter plate 13. The filtered silicon powder will naturally fall into the collecting bucket 24, and the filtered air is discharged out of the box body 11 through the exhaust fan 14. When too much silicon powder remains attached to one side of the filter plate 13, the motor 22 is started through an external power supply, and the output end of the motor 22 drives the first threaded rod 221 to rotate. The rotating first threaded rod 221 drives the scraper 23 to move up and down on one side of the filter plate 13 through the second threaded sleeve 222, so that the silicon powder remaining attached to one side of the filter plate 13 is scraped into the collecting bucket 24, so as to avoid too much silicon powder remaining attached to one side of the filter plate 13, thereby improving the recovery efficiency of the silicon powder.

[0064] It can be seen from the above description that the beneficial effects of the embodiments of the utility model are:

[0065] The output end of the motor 22 drives the first threaded rod 221 to rotate, and the rotating first threaded rod 221 drives the scraper 23 to move up and down on one side of the filter plate 13 through the second threaded sleeve 222, and scrapes the silicon powder remaining attached to one side of the filter plate 13 into the collecting bucket 24, so as to avoid excessive silicon powder remaining attached to one side of the filter plate 13, thereby improving the recovery efficiency of the silicon powder. At the same time, the first threaded rod 221 drives the second threaded rod 26 to rotate through the gear 25, and the rotating second threaded rod 26 drives the brush 27 to move up and down on the other side of the filter plate 13 through the second threaded sleeve 261, so that the brush 27 sweeps away the silicon powder blocked in the filter holes on the filter plate 13, thereby avoiding the filter holes on the filter plate 13 being blocked by silicon powder.
