[0001] This utility model relates to the field of copper powder sieving technology, specifically a sieving device for extracting copper powder from graphite powder. Background Technology

[0002] In some industrial production processes, a mixture of graphite powder and copper powder is generated as waste. In order to save resources and reduce waste, these two substances can be separated by a screening device so that they can be recycled and utilized separately.

[0003] In the existing technology, a mixture of graphite powder and copper powder is fed onto the screen of a screening cylinder. A vibrating device is used to vibrate the screen, causing the graphite powder and copper powder in the mixture to jump and roll on the screen according to their particle size difference. The relatively smaller graphite powder particles penetrate the screen mesh and fall into the collection container below, while the relatively larger copper powder particles are intercepted above the screen, thus achieving the screening effect of both.

[0004] The existing technology has the following drawbacks: During the sieving process, both graphite powder and copper powder are fine-particle solid substances. When they are subjected to vibration, dust is generated due to the collision and friction between the particles. This dust may contaminate the sieved product, affecting its purity and quality. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a sieving device for extracting copper powder from graphite powder. This sieving device solves the problem in the prior art where dust generated during the sieving process may contaminate the sieved product, affecting the purity and quality of the product.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1-4 As shown, a sieving device for extracting copper powder from graphite powder includes: a box body 1, an inclined feed pipe 2 on the box body 1, through which a mixture of graphite powder and copper powder can be added into the box body 1; a screen 6 is detachably installed inside the box body 1; the screen 6 separates the graphite powder and copper powder in the mixture through its specific aperture size; and a collection box 8 is fixedly installed inside the box body 1 and below the screen 6.

[0022] The inner walls on both sides of the housing 1 are provided with fixing grooves 5. One of the fixing grooves 5 is connected to the outside. The screen 6 is installed in both fixing grooves 5. The height of the fixing groove 5 is greater than the height of the screen 6, so that the screen 6 has a certain space to vibrate. A sealing block 12 is installed in the fixing groove 5 connected to the outside. The sealing block 12 is fixed to the outer wall of the housing 1 by bolts. The sealing block 12 is convex and is used to block the fixing groove 5.

[0023] A vibration mechanism is provided below the screen 6. The vibration mechanism includes a motor 4 that is symmetrically fixed on the outside of the box 1. The output end of the motor 4 passes through the side wall of the box 1 and is eccentrically connected to a circular plate 7.

[0024] When motor 4 is started, its output drives the corresponding circular plate 7 to rotate. The circular plate 7 causes the screen 6 to move up and down in the fixed groove 5, which causes the screen 6 to vibrate. This causes the graphite powder and copper powder in the mixture to jump and roll on the screen 6 according to their particle size difference. The relatively smaller graphite powder particles penetrate the holes of the screen 6 and fall into the collection box 8 below, while the relatively larger copper powder particles are intercepted above the screen 6. By removing the sealing block 12 and taking the screen 6 out of the fixed groove 5 that is connected to the outside, the copper powder above the screen 6 can be removed.

[0025] A switch door 11 is provided on the side wall of the box 1 near the collection box 8. A notch is provided on the box 1 to accommodate the switch door 11. By removing the switch door 11 from the notch of the box 1, the collection box 8 can be removed from the notch of the box 1.

[0026] The interior of the housing 1 is provided with an air outlet pipe 3 and an air inlet pipe 9. The end of the air inlet pipe 9 inside the housing 1 is connected to a dust collection hood 10. A fixed box 13 is fixedly installed on the front side of the housing 1. The ends of the air outlet pipe 3 and the air inlet pipe 9 on the outside of the housing 1 are both connected to the fixed box 13. A fan 14 is provided inside the fixed box 13. A screening plate 16 is detachably installed inside the fixed box 13.

[0027] During screening, the blower 14 is started. The operation of the blower 14 creates a negative pressure on one side, and the dust generated during the vibration is sucked into the fixed box 13 through the air inlet pipe 9 and the dust suction hood 10. After being filtered by the screening plate 16, the gas is discharged from the air outlet pipe 3 on the left side of the blower 14 and discharged into the box 1.

[0028] The screening plate 16 and the fixing box 13 can be detachably installed as follows: a slot for inserting the screening plate 16 is opened on one side of the inner wall of the fixing box 13, and an insertion port for the screening plate 16 to pass through is opened on the other side of the fixing box 13. A clamping block 15 is provided at the end of the screening plate 16 located outside the fixing box 13. The clamping block 15 is used to clamp the screening plate 16, so that the screening plate 16 can be pulled out to clean the dust on the screening plate 16.

[0029] A sealing block 17 is detachably installed at the bottom of the fixed box 13 and at the position corresponding to the screening plate 16. The sealing block 17 is convex in shape. A slot for the sealing block 17 to be engaged is opened at the bottom of the fixed box 13. The slot is connected to the outside.

[0030] Some of the dust filtered by the screening plate 16 is adsorbed on the screening plate 16, while the other part of the dust falls to the upper end of the sealing block 17. Due to the detachable design of the sealing block 17, the sealing block 17 can be removed to process the dust on the upper end of the sealing block 17.

[0031] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
