[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1-4 As shown, a sandblasting machine filtration device includes a chamber 11 and a filter plate 12 installed inside the chamber 11. A sand storage bin 16 is fixedly connected to the bottom of the chamber 11. A material cylinder 13 is rotatably connected to the top of the chamber 11. Multiple partitions 15 are fixedly connected in an annular shape inside the material cylinder 13. Multiple filtration chambers are divided inside the material cylinder 13 by the partitions 15. The filter plate 12 is arranged in a semi-circular structure, and the material cylinder 13 is located inside the filter plate 12 and slides with it. A reduction motor 14 is fixedly connected to the side of the chamber 11, and the output end of the reduction motor 14 is fixedly connected to the material cylinder 13.

[0025] In use, the geared motor 14 drives the material cylinder 13 to rotate, and the abrasive is put into the filter chamber. The rotation of the material cylinder 13 drives the abrasive to move inside the filter plate 12. The abrasive falls from the filter holes on the filter plate 12 into the sand storage bin 16 below. Large particles of impurities are pushed by the partition 15 and then discharged from the other side of the filter plate 12. Therefore, it is easy to discharge impurities, thereby reducing the accumulation of impurities on the filter plate 12 and reducing the impact on the filtration speed. In addition, the filter plate 12 is set with a semi-circular structure, which can increase the surface area of ​​the filter plate 12 and facilitate filtration.

[0026] Furthermore, such as Figure 1-5As shown, a rotating shaft 21 is rotatably connected to the middle of the filter chamber. The rotating shaft 21 passes through the side wall of the filter chamber, and a gear 22 is fixedly connected to the end of the rotating shaft 21. A semi-toothed ring 23 is fixedly connected to the inner side wall of the chamber body 11 at a position corresponding to the gear 22. The gear 22 and the semi-toothed ring 23 mesh with each other. Multiple stirring blades 24 are fixedly connected to the rotating shaft 21. In use, the rotation of the material cylinder 13 will drive the rotating shaft 21 to rotate. During the rotation, the gear 22 and the semi-toothed ring 23 mesh, which will cause the rotating shaft 21 to rotate, thereby causing the rotating shaft 21 and the stirring blades 24 on the rotating shaft 21 to rotate. This allows the abrasive to move inside the filter chamber, thus facilitating filtration.

[0027] Furthermore, such as Figure 2-3 As shown, the filter plate 12 has a discharge port 31 on its top side. A hopper 32 is fixedly connected to the inner wall of the hopper body 11. The hopper 32 penetrates the side wall of the hopper body 11, and the top of the hopper 32 corresponds to the position of the discharge port 31. A dust cover 41 is fixedly connected to the top of the hopper body 11. The top of the material cylinder 13 is inserted into the dust cover 41. A feed hopper 42 is fixedly connected to the side of the dust cover 41. In use, the dust cover 41 above the material cylinder 13 can act as a dust cover, thereby reducing dust during the filtration process. The feed hopper 42 can conveniently receive the abrasive recovered by the sandblasting machine. The discharge port 31 lowers the discharge height, making it easier to discharge impurities. The hopper 32 can facilitate the guidance and discharge of impurities.

[0028] Furthermore, such as Figure 5 As shown, multiple augers 6 are fixedly connected to the rotating shaft 21, and the augers 6 are located between two closely spaced stirring blades 24. In use, the rotation of the rotating shaft 21 will drive the augers 6 to rotate inside the filter chamber, which can facilitate the movement of abrasives inside the filter chamber, thereby facilitating filtration.

[0029] Furthermore, such as Figure 2 As shown, an inclined plate 51 is fixed to the bottom inner wall of the chamber 11. The inclined plate 51 is located at the bottom of the filter plate 12, and an electromagnet 52 is installed at the bottom of the inclined plate 51. When in use, the electromagnet 52 is energized and becomes magnetic. The abrasive filtered by the filter plate 12 falls onto the inclined plate 51. The electromagnet 52 at the bottom of the inclined plate 51 can adsorb some fine metal dust and fragments, reducing impurities inside the abrasive.

[0030] Furthermore, such as Figure 2As shown, the partition 15 has multiple through holes 7. The diameter of the through holes 7 is the same as the diameter of the filter holes of the filter plate 12. The through holes 7 allow the multiple filter chambers formed by the partition 15 to be interconnected. When too much abrasive is added, the abrasive will fall into the filter chamber located in the lower layer through the through holes 7 on the partition 15, thereby reducing the situation where the abrasive is discharged from the discharge port 31.

[0031] Working principle: During use, the geared motor 14 drives the material cylinder 13 to rotate, and the abrasive is put into the filter chamber. The rotation of the material cylinder 13 drives the abrasive to move inside the filter plate 12. The abrasive falls from the filter holes on the filter plate 12 into the sand storage bin 16 below. Large particles of impurities are pushed by the baffle 15 and then discharged from the other side of the filter plate 12. This facilitates the discharge of impurities, thereby reducing the accumulation of impurities on the filter plate 12 and reducing the impact on the filtration speed. The filter plate 12 has a semi-circular structure, which increases the surface area of ​​the filter plate 12, facilitating filtration. During use, the rotation of the material cylinder 13 drives the rotating shaft 21 to rotate. During the rotation, the gear 22 and the semi-tooth ring 23 mesh, which causes the rotating shaft 21 to rotate, thereby causing the rotating shaft 21 and the stirring blades 24 on the rotating shaft 21 to rotate. The abrasive material moves within the filter chamber, facilitating filtration. A dust cover 41 above the material cylinder 13 acts as a dustproof barrier, reducing dust generation during filtration. A feed hopper 42 collects abrasive recovered from the sandblasting machine. A discharge port 31 lowers the discharge height, facilitating impurity removal. The discharge hopper 32 guides impurities out of the filter chamber. The rotation of the shaft 21 drives the auger 6 within the filter chamber, further propelling the abrasive material and aiding filtration. During operation, the electromagnet 52 is energized, activating its magnetism. Abrasive material filtered by the filter plate 12 falls onto the inclined plate 51, where the electromagnet 52 at the bottom of the inclined plate 51 attracts fine metal dust particles, reducing impurities within the abrasive material.
