Description

Technical Field

[0001] The invention relates to the technical field of silicon raw material crushing, and more specifically to a raw material particle crushing device for silicon material production. Background Art

[0002] In the processing of silicon products, in order to purify silicon materials, silicon raw material particles are generally crushed. In the medium and fine crushing stage, impact crushers are generally used to crush silicon raw material particles.

[0003] The impact crusher uses high-speed rotating hammers to hit the material. After the material gains kinetic energy, it flies to the impact plate. After hitting the impact plate, the material rebounds to the hammer area and is hit by the hammer again. At the same time, the materials will collide with each other, resulting in multiple crushing. The discharge particle size is controlled by adjusting the gap between the impact plate and the rotor.

[0004] Although impact crushers are widely used in the field of medium and fine crushing, they still have the following shortcomings when crushing silicon material particles:

[0005] First, silicon raw material particles will produce silicon dust when they are crushed, and the high-speed rotating hammer will aggravate the escape of silicon dust, thus causing environmental pollution and even triggering dust explosions;

[0006] Secondly, when the moisture content of silicon raw material particles is greater than 5%, the silicon raw material particles are easy to adhere to the surface of the counter-attack plate. If they are not cleaned in time, the striking effect of the counter-attack plate will be affected;

[0022] Technical effects and advantages of the present invention:

[0023] 1. The present invention is provided with an impact plate air duct mechanism. When the device crushes silicon raw material particles, the fan starts to draw air into the dust collection box. The silicon dust generated during the crushing of the silicon raw material particles is sucked in through the dust suction air duct, enters the inner cavity of the cavity plate strip through the through groove, is sucked into the air bin through the dust suction pipe and finally enters the dust collection box. The dust filtering plate intercepts the silicon dust and filters the air flow.

[0024] 2. The present invention is provided with a storage component. When the moisture content of the silicon raw material particles is high, the silicon raw material particles are likely to adhere to the front side surface of the impact plate member. At this time, the liquid pump can be used to drive the piston shaft to contract, thereby driving the cavity plate strip to be stored in the storage groove. Then, the flipping motor drives the flipping shaft to drive the impact plate member to flip by 180 degrees, so that the front side and the back side of the impact plate member are alternated. Then, the liquid pump drives the piston shaft to drive the cavity plate strip to be pushed into the inner groove again. During the pushing process, the cleaning surface can clean the surface of the impact plate member that adhered to the silicon raw material particles before. After the pushing is completed, the dust suction pipe is reconnected to the dust suction hole. Through the above method, the silicon raw material particles adhered to the impact plate member can be cleaned in a timely and convenient manner. BRIEF DESCRIPTION OF THE DRAWINGS

When the cavity strip 604 is stored in the storage groove 902, the turning motor 805 drives the impact plate member 601 to turn;

[0049] In this embodiment, when the moisture content of the silicon raw material particles is high, the silicon raw material particles are likely to adhere to the front side of the impact plate member 601. At this time, the liquid pump 909 can be used to drive the piston shaft 904 to contract, thereby driving the cavity strip 604 to be stored in the storage groove 902. Then, the turning motor 805 drives the turning shaft 609 to drive the impact plate member 601 to turn 180 degrees, so that the front side and the back side of the impact plate member 601 are alternated. Then, the liquid pump 909 drives the piston shaft 904 to drive the cavity strip 604 to be pushed back into the inner groove 603 again.

[0051] In this embodiment, the adjustment motor 1003 drives the push rod 1002 to make the back plate 501, the air chamber 801, and the storage plate 901 move synchronously.

Extension plates 108 are connected between the right sealing plate 802, the storage plate 901, the inner side wall surface of the body housing 102, and the side plates 107. The deformation effect of the extension plate 108 allows the air chamber 801 and the storage plate 901 to rotate around the adjustment shaft 503 to perform fine angle adjustment.

[0053] The working principle of the present invention: When the device crushes silicon raw material particles, the blower 808 starts to draw air into the dust collection box 806. The silicon dust generated during the crushing of the silicon raw material particles is sucked in through the dust suction air duct and enters the inner cavity of the cavity plate strip 604 through the through groove 606. The silicon dust is sucked into the air chamber 801 through the dust suction pipe 7 and finally enters the dust collection box 806. The dust filtering plate 809 intercepts the silicon dust and filters the air flow. In this way, the silicon dust generated during the crushing of the silicon raw material particles is collected in the dust collection box 806, thereby solving the environmental pollution caused by the escape of silicon dust and the problem of easy occurrence of dust explosion. When the moisture content of the silicon raw material particles is high, the silicon raw material particles are likely to adhere to the front side surface of the impact plate member 601. At this time, the liquid pump 909 can be used to drive the piston shaft 904 to contract, thereby driving the cavity plate strip 604 to be received in the receiving groove 902. Then, the flipping motor 805 drives the flipping shaft 609 to drive the impact plate member 601 to perform a 180-degree flip, so that the front side and the back side of the impact plate member 601 are alternated. Then, the liquid pump 909 drives the piston shaft 904 to drive the cavity plate strip 604 to be pushed back into the inner groove 603 again. During the pushing process, the cleaning surface 605 can clean the surface of the impact plate member 601 that adhered to the silicon raw material particles before. After the pushing is completed, the dust suction pipe 7 is reconnected to the dust suction hole 803. Through the above method, the silicon raw material particles adhered to the impact plate member 601 can be cleaned in a timely and convenient manner.
