[0027] See also Figures 1 to 5The utility model provides a technical solution: a negative pressure collection device for silicon micropowder, comprising a box body 1 and a collection box 2, the end of the collection box 2 is inserted into the interior of the rectangular installation groove, the outer side of the collection box 2 is sealed and abutted against the sealing block 17, and support legs 25 are installed on both sides of the box body 1, the end of the convex sliding block 23 is located inside the convex sliding groove, and the convex sliding block 23 can slide along the length direction of the convex sliding groove. An air inlet pipe 3 is installed on one side of the box body 1, and a ventilation pipe 4 is installed on the inner wall of the box body 1. A filter screen 5, a strip plate 6 and a negative pressure fan 7 are respectively installed inside the ventilation pipe 4. A T-shaped sliding groove with the front and rear direction as the depth direction and the left and right direction as the length direction is opened inside the strip plate 6. The end of the T-shaped sliding block 12 is located inside the T-shaped sliding groove, and the T-shaped sliding block 12 can slide along the length direction of the T-shaped sliding groove. One end of the ventilation pipe 4 corresponds to the position of the air inlet pipe 3, and the other end of the ventilation pipe 4 corresponds to the position of the air outlet. The position of the negative pressure fan 7 corresponds to the position of the dustproof net 18. The servo motor 8 and the negative pressure fan 7 are electrically connected to the external power supply through wires. The servo motor 8 is installed on the top of the ventilation pipe 4, and the output end of the servo motor 8 is installed with a first support rod 9. The bottom of the first support rod 9 is rotatably connected to the second support rod 10 through an axle rod, and the top of the second support rod 10 is rotatably connected to the cross plate 11 through an axle rod. T-shaped sliders 12 are installed in the front and back of the cross plate 11. A spring cylinder 13 is installed on one side of the cross plate 11, and a return spring 14 is installed inside the spring cylinder 13. A spring rod 15 is installed at one end of the return spring 14, and the end of the spring rod 15 away from the impact block 16 is located inside the spring cylinder 13. The position of the filter screen 5 corresponds to the position of the impact block 16 and the collection box 2 respectively, and the end of the spring rod 15 is installed with the impact block 16. The interior of the ventilation pipe 4 is respectively provided with an inclined blanking port and a rectangular mounting groove, and a sealing block 17 is installed inside the rectangular mounting groove. An air outlet is opened on one side of the box body 1, and a dustproof net 18 is arranged inside the air outlet.

[0028] When in use, when collecting silicon micropowder, the negative pressure fan 7 works to generate negative pressure wind, so that the wind and silicon micropowder enter the interior of the ventilation pipe 4 through the air inlet pipe 3, and the wind passes through the filter 5 and is discharged from the vent. The filter 5 blocks the silicon micropowder, so that the silicon micropowder falls into the interior of the collection box 2 through the inclined drop chute. The servo motor 8 drives the first support rod 9 to rotate, and the second support rod 10 is respectively connected to the first support rod 9 and the cross plate 11. The second support rod 10 and the first support rod 9 rotate and connect to each other at the rotation connection point, and the second support rod 10 moves in a circle with the output end axis of the servo motor 8 as the center. The movement of the second support rod 10 provides a component force in the left and right directions for the cross plate 11, and the end of the T-shaped slider 12 is located inside the T-shaped slide groove, so that the cross plate 11 drives the T-shaped slider 12 and the impact block 16 to move back and forth, and the impact block 16 impacts the filter screen 5 to play a vibrating screen role, thereby preventing the mesh of the filter screen 5 from being blocked and facilitating the circulation of air.

[0031] When in use, when disassembling the collection box 2, pull the limit block 24, so that the limit block 24 drives the convex sliding block 23 to move, so that the limit spring 22 contracts, and the convex sliding block 23 is positioned and moved along the length direction of the convex sliding groove, so that the end of the limit block 24 leaves the limit groove, and the collection box 2 is moved downward, so that the positioning block 20 leaves the positioning groove, and the end of the collection box 2 leaves the rectangular installation groove. When the highest point of the collection box 2 is lower than the lowest position of the front wall of the box body 1, move the collection box 2 forward to facilitate the collection box 2 to be taken out of the box body 1. The silicon micropowder inside is poured out. During installation, the end of the collecting box 2 is inserted into the interior of the rectangular installation groove, so that the collecting box 2 abuts against the sealing block 17. The sealing block 17 improves the sealing of the connection, so that the positioning block 20 enters the interior of the positioning groove. When the end of the positioning block 20 reaches the end of the positioning groove, the limit groove is aligned with the limit block 24. The limit block 24 is loosened, and the end of the limit block 24 is inserted into the interior of the limit groove through the elastic tension of the limit spring 22, which is convenient for limiting the position of the positioning block 20 and facilitating the installation of the collecting box 2.
