Technical Field

[0001] This utility model relates to the field of high-purity silicon processing technology, and in particular to a purification device. Background Technology

[0002] High-purity silicon is a raw material obtained by special purification processes such as screening, crushing, chlorination, and comprehensive selection of crystalline silicon raw materials (also known as synthetic crystal powder). The raw materials are then smelted to obtain high-purity crystalline silicon, which is a material used in the manufacture of semiconductors, integrated circuits, and photovoltaic cells.

[0003] In existing technologies, the removal of impurities from high-purity silicon requires filtering the silicon through a filter screen. However, after prolonged use, the pores of the filter screen are easily clogged by impurities, thus affecting the normal processing of high-purity silicon. Utility Model Content

[0004] This utility model proposes a purification device to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning device, comprising a housing, the housing being supported by legs placed on the ground, a feed pipe fixedly connected to the upper surface of the housing, a filter screen installed inside the housing, wherein the filter screen is inclined, a pre-drilled hole is provided on the housing corresponding to the filter screen, two guide plates are installed inside the housing, wherein the guide plates are located at the bottom of the filter screen, a collection frame is slidably inserted at the bottom of the housing, wherein one side of the guide plate is located directly above the collection frame, and a striking device is installed inside the housing, wherein the striking device can repeatedly strike the filter screen.

[0006] The effect achieved by the above components is as follows: when high-purity silicon needs to be processed, the operator feeds the high-purity silicon into the interior of the shell through the feed pipe. The inclined filter screen filters the impurities in the high-purity silicon, and the high-purity silicon passes through the filter screen and is guided to the collection frame by the guide plate. The impurities are discharged from the shell through the reserved holes. At the same time, the striking device repeatedly strikes the filter screen to prevent the impurities from clogging the holes of the filter screen.

[0007] Preferably, the striking device includes a motor installed inside the housing. The motor is fixedly connected to a first sprocket via a reducer. An eccentric circle is fixedly connected to one side of the first sprocket. The support rod slides through one of the guide plates. A U-shaped plate is fixedly connected to one end of the support rod, with the U-shaped plate located directly above the eccentric circle. A striking block is fixedly connected to the other end of the support rod. A spring is sleeved on the arc surface of the support rod, and both ends of the spring are fixedly connected to the U-shaped plate and the guide plate, respectively.

[0008] The effect achieved by the above components is as follows: When it is necessary to tap the filter screen, the operator turns on the motor. The motor drives the first sprocket and the eccentric circle to rotate through the reducer. When the protruding end of the eccentric circle moves to the position of the U-shaped plate, the eccentric circle squeezes the U-shaped plate. The U-shaped plate, along with the support rod and the tapping block, moves towards the filter screen. The spring deforms. When the protruding end of the eccentric circle moves away from the U-shaped plate, under the action of the spring's restoring force, the U-shaped plate moves back to its original position, and the tapping block moves away from the filter screen. As the eccentric circle continues to rotate, the tapping block continuously taps the filter screen, achieving the effect of cleaning the filter screen. The tapping device achieves the effect of cleaning the filter screen, preventing impurities in the high-purity silicon from clogging the filter screen and causing the high-purity silicon to be unable to pass through the filter screen.

[0009] Preferably, a rubber pad is fixedly connected to the top of the striking block, wherein the size of the rubber pad is adapted to the size of the striking block.

[0010] The effect achieved by the above components is that the rubber pads protect the filter screen and prevent the impact blocks from damaging it.

[0011] Preferably, a telescopic rod is fixedly connected to the bottom of the striking block, wherein one end of the telescopic rod is fixedly connected to the guide plate.

[0012] The effect achieved by the above components is that by setting up the telescopic rod, the direction of movement of the support rod is restricted, thus preventing the support rod from rotating.

[0013] Preferably, the two arms of the U-shaped plate are rotatably connected to rotating components, wherein the arc surface of the rotating components is in contact with the eccentric circle.

[0014] The effect achieved by the above components is that the friction between the U-shaped plate and the eccentric circle is reduced by the mutual rotation of the rotating component and the eccentric circle.

[0015] Preferably, an auxiliary device is provided inside the outer casing. The auxiliary device includes a second sprocket, the two arms of which are rotatably connected to the interior of the outer casing. A chain is fitted onto the arc surfaces of the first and second sprockets. A push plate is fixedly connected to the arc surface of the second sprocket. The wiping plate is positioned above the filter screen. A rotating rod is rotatably connected to the surface of the wiping plate. Both ends of the rotating rod are fixedly connected to the outer casing. A fixing rod is fixedly connected to one end of the wiping plate. A coil spring is fitted onto the arc surface of the rotating rod. Both ends of the coil spring are fixedly connected to the wiping plate and the inner wall of the outer casing, respectively.

[0016] The effect achieved by the above components is as follows: When the first sprocket rotates, it drives the second sprocket to rotate via a chain. When the push plate on the second sprocket moves to the position of the fixed rod, the push plate drives the fixed rod and the squeegee to rotate. The squeegee smooths the high-purity aluminum on the filter screen. The coil spring on the rotating rod deforms. When the push plate moves past the fixed rod, the squeegee returns to its original position under the action of the spring's return force. As the first sprocket rotates continuously with the push plate, the squeegee swings continuously. The squeegee, set by the auxiliary device, swings continuously above the filter screen, thereby achieving the effect of smoothing the high-purity aluminum on the filter screen and preventing the high-purity aluminum on the filter screen from accumulating together.

[0017] Preferably, a triangular plate is fixedly connected to the upper surface of the push plate, wherein the tip of the triangular plate is away from the push plate.

[0018] The effect achieved by the above components is that by setting up the triangular plate, the high-purity aluminum is guided, thus preventing the high-purity aluminum from accumulating on the push plate.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] When it is necessary to tap the filter screen, the operator turns on the motor. The motor drives the first sprocket and the eccentric circle to rotate through the reducer. When the protruding end of the eccentric circle moves to the position of the U-shaped plate, the eccentric circle squeezes the U-shaped plate. The U-shaped plate, along with the support rod and the tapping block, moves towards the filter screen. The spring deforms. When the protruding end of the eccentric circle moves away from the U-shaped plate, the U-shaped plate moves back to its original position under the action of the spring's restoring force. The tapping block moves away from the filter screen. As the eccentric circle continues to rotate, the tapping block continuously taps the filter screen, achieving the effect of cleaning the filter screen. The tapping device achieves the effect of cleaning the filter screen, preventing impurities in the high-purity silicon from clogging the filter screen and causing the high-purity silicon to be unable to pass through the filter screen.

[0026] Reference Figure 1-4 As shown, this embodiment discloses a high-purity silicon-based material impurity removal device, including a housing 1, which is supported by legs placed on the ground. A feed pipe 2 is fixedly connected to the upper surface of the housing 1; a filter screen 3, which is installed inside the housing 1 and is inclined. A pre-drilled hole 4 is provided on the housing 1 corresponding to the filter screen 3; two guide plates 6, which are installed inside the housing 1 and are located at the bottom of the filter screen 3; a collection frame 5, which is slidably installed at the bottom of the housing 1, with one side of the guide plate 6 located directly above the collection frame 5; and a tapping device 7, which is installed inside the housing 1 and can repeatedly tap the filter screen 3. When high-purity silicon needs to be processed, the staff feeds the high-purity silicon into the interior of the outer shell 1 through the feed pipe 2. The inclined filter screen 3 filters the impurities in the high-purity silicon, and the high-purity silicon passes through the filter screen 3 and is guided by the guide plate 6 to the collection frame 5. The impurities are discharged from the outer shell 1 through the reserved hole 4. At the same time, the striking device 7 repeatedly strikes the filter screen 3 to prevent the impurities from clogging the holes of the filter screen 3.

[0027] Reference Figure 1-4As shown, the striking device 7 includes a motor 71, which is installed inside the housing 1. The motor 71 is fixedly connected to a first sprocket 72 via a reducer. An eccentric circle 73 is fixedly connected to one side of the first sprocket 72. A support rod 74 slides through one of the guide plates 6. A U-shaped plate 76 is fixedly connected to one end of the support rod 74, which is located directly above the eccentric circle 73. A striking block 77 is fixedly connected to the other end of the support rod 74. A spring 75 is sleeved on the arc surface of the support rod 74. Both ends of the spring 75 are fixedly connected to the U-shaped plate 76 and the guide plate 6, respectively. When it is necessary to tap the filter screen 3, the operator turns on the motor 71. The motor 71 drives the first sprocket 72 and the eccentric circle 73 to rotate through the reducer. When the protruding end of the eccentric circle 73 moves to the position of the U-shaped plate 76, the eccentric circle 73 squeezes the U-shaped plate 76. The U-shaped plate 76, along with the support rod 74 and the tapping block 77, moves towards the filter screen 3. The spring 75 deforms. When the protruding end of the eccentric circle 73 moves away from the U-shaped plate 76, under the action of the spring 75's restoring force, the U-shaped plate 76 moves back to its original position, and the tapping block 77 moves away from the filter screen 3. As the eccentric circle 73 continues to rotate, the tapping block 77 continuously taps the filter screen 3, achieving the effect of cleaning the filter screen 3. The tapping device 7 achieves the effect of cleaning the filter screen 3, preventing impurities in the high-purity silicon from clogging the filter screen 3, thus preventing the high-purity silicon from passing through the filter screen 3.

[0028] Reference Figure 1-4 As shown, a rubber pad 79 is fixedly connected to the top of the striking block 77, and the size of the rubber pad 79 is adapted to the size of the striking block 77. The rubber pad 79 protects the filter screen 3, preventing the striking block 77 from damaging it. A telescopic rod 710 is fixedly connected to the bottom of the striking block 77, with one end of the telescopic rod 710 fixedly connected to the guide plate 6. The telescopic rod 710 restricts the movement direction of the support rod 74, preventing it from rotating. Rotating components 78 are rotatably connected to the two arms of the U-shaped plate 76, with the arc surface of the rotating component 78 fitting against the eccentric circle 73. The mutual rotation of the rotating component 78 and the eccentric circle 73 reduces the friction between the U-shaped plate 76 and the eccentric circle 73.

[0029] Reference Figure 1-4As shown, an auxiliary device 8 is provided inside the outer casing 1. The auxiliary device 8 includes a second sprocket 82, the two arms of which are rotatably connected to the inside of the outer casing 1. A chain 81 is fitted onto the arc surfaces of the first sprocket 72 and the second sprocket 82. A push plate 83 is fixedly connected to the arc surface of the second sprocket 82. A wiping plate 84 is positioned above the filter screen 3. A rotating rod 86 is rotatably connected to the surface of the wiping plate 84. Both ends of the rotating rod 86 are fixedly connected to the outer casing 1. A fixing rod 85 is fixedly connected to one end of the wiping plate 84. A coil spring 88 is fitted onto the arc surface of the rotating rod 86. Both ends of the coil spring 88 are fixedly connected to the wiping plate 84 and the inner wall of the outer casing 1, respectively. When the first sprocket 72 rotates, it drives the second sprocket 82 to rotate via the chain 81. When the push plate 83 on the second sprocket 82 moves to the position of the fixed rod 85, the push plate 83 drives the fixed rod 85 and the smearing plate 84 to rotate. The smearing plate 84 smooths the high-purity aluminum on the filter screen 3. The coil spring 88 on the rotating rod 86 deforms. When the push plate 83 moves past the fixed rod 85, the smearing plate 84 returns to its original position under the action of the return spring force of the coil spring 88. As the first sprocket 72 rotates continuously with the push plate 83, the smearing plate 84 swings continuously. The smearing plate 84 set by the auxiliary device 8 swings continuously above the filter screen 3, thereby achieving the effect of smoothing the high-purity aluminum on the filter screen 3 and preventing the high-purity aluminum on the filter screen 3 from accumulating together.

[0030] Reference Figure 1-4 As shown, a triangular plate 87 is fixedly connected to the upper surface of the push plate 83, with the tip of the triangular plate 87 away from the push plate 83. By setting the triangular plate 87, the high-purity aluminum is guided, preventing it from accumulating on the push plate 83.

[0031] Working principle: When high-purity silicon needs to be processed, the operator feeds the high-purity silicon into the interior of the outer shell 1 through the feed pipe 2. The inclined filter screen 3 filters out impurities in the high-purity silicon, while the high-purity silicon passes through the filter screen 3 and is guided by the guide plate 6 to the collection frame 5. Impurities are discharged from the outer shell 1 through the reserved hole 4. At this time, the operator turns on the motor 71. The motor 71 drives the first sprocket 72 and the eccentric circle 73 to rotate with the help of the reducer. When the protruding end of the eccentric circle 73 moves to the position of the U-shaped plate 76, the eccentric circle 73 squeezes the U-shaped plate 76 with the help of the rotating part 78. The U-shaped plate 76, along with the support rod 74 and the striking block 77, moves towards the filter. As the filter screen 3 moves, the striking block 77 strikes the filter screen 3 with the help of the rubber pad 79. The spring 75 deforms. When the protruding end of the eccentric circle 73 moves away from the U-shaped plate 76, the U-shaped plate 76 moves back to its original position under the action of the spring 75's restoring force. The striking block 77 moves away from the filter screen 3. As the eccentric circle 73 continues to rotate, the striking block 77 continuously strikes the filter screen 3, achieving the effect of cleaning the filter screen 3. The striking device 7 achieves the effect of cleaning the filter screen 3, preventing impurities in the high-purity silicon from clogging the filter screen 3, thus preventing the high-purity silicon from passing through the filter screen 3.

[0032] When the first sprocket 72 rotates, it drives the second sprocket 82 to rotate via the chain 81. When the push plate 83 on the second sprocket 82 moves to the position of the fixed rod 85, the push plate 83 drives the fixed rod 85 and the smearing plate 84 to rotate. The smearing plate 84 smooths the high-purity aluminum on the filter screen 3. The coil spring 88 on the rotating rod 86 deforms. When the push plate 83 moves past the fixed rod 85, the smearing plate 84 returns to its original position under the action of the return spring force of the coil spring 88. As the first sprocket 72 rotates continuously with the push plate 83, the smearing plate 84 swings continuously. The smearing plate 84 set by the auxiliary device 8 swings continuously above the filter screen 3, thereby achieving the effect of smoothing the high-purity aluminum on the filter screen 3 and preventing the high-purity aluminum on the filter screen 3 from accumulating together.
