Technical Field
[0001] This utility model relates to the field of silicon material screening technology, specifically an anti-clogging silicon material screening machine. Background Technology
[0002] Silicon material refers to materials whose main component is silicon, typically including polycrystalline silicon and monocrystalline silicon. The purity and crystal structure of silicon material have a crucial impact on its electrical properties and applications. During the use of silicon material, screening is necessary to ensure its purity, and this screening process requires a screening machine. A silicon material screening machine is a specialized device for screening silicon materials (such as silica sand, silica powder, and silicon particles). It is widely used in the production process of silicon materials, especially in semiconductors, solar cells, glass manufacturing, and other related industries, for material screening, grading, and cleaning. Silicon material screening machines can efficiently separate silicon materials of different particle sizes, ensuring the quality and consistency of the final product.
[0003] However, most existing silicon material screening machines are inconvenient to clean during use, and are prone to clogging after prolonged use, which affects the subsequent screening effect. As a result, these screening machines cannot meet more usage needs and are not practical enough. Therefore, an anti-clogging silicon material screening machine is proposed to address the above problems. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is: the anti-clogging silicon material screening machine of this utility model includes a support frame, and a screening box is provided on the top of the support frame through a support component;
[0006] The support assembly includes support plates fixedly connected to the front and rear of the bottom of the screening box. Connecting rods are fixedly connected through the left and right sides between the two support plates. Support blocks are fixedly connected through the front and rear ends of the connecting rods. Support springs are fixedly connected between the four support blocks and the support frame. Two vibration motors are fixedly installed at the bottom of the screening box through the connecting blocks.
[0007] The screening box has a screening trough inside. Screening mesh one and screening mesh two are fixedly connected to the upper and lower parts of the screening trough, respectively. Through slots are opened at the upper and lower parts of the front surface of the screening trough. Collection slots are opened at the upper and lower parts of the left side of the screening trough. A moving component is provided on the front surface of the screening box. The left side of the rear surface of the moving component extends into the collection slot and is equipped with an anti-clogging cleaning brush. From top to bottom, discharge pipe one, discharge pipe two, and discharge pipe three are fixedly connected to the right side of the screening box. Discharge pipe one, discharge pipe two, and discharge pipe three are all connected to the inside of the screening trough.
[0008] Preferably, the moving component includes a connecting plate one and a connecting plate two fixedly connected to the left and right sides of the screening box, respectively. A threaded rod is rotatably connected between the connecting plate one and the connecting plate two via a bearing. A drive motor is fixedly installed on the left side of the connecting plate one, and the output end of the drive motor is fixedly connected to the left end of the threaded rod. Limiting rods are fixedly connected above and below the connecting plate one and the connecting plate two. An internally threaded sliding plate is threadedly connected to the left side of the outer surface of the threaded rod. The limiting rod passes through the internally threaded sliding plate and is slidably connected to the internally threaded sliding plate. A slider is fixedly connected above and below the rear surface of the internally threaded sliding plate. The rear surface of the slider passes through a through groove and is located inside a receiving groove. The slider is fixedly connected to an anti-clogging cleaning brush.
[0009] Preferably, a limiting groove is provided above and below the rear surface of the screening tank, a limiting block is slidably connected inside the limiting groove, the limiting block is fixedly connected to the anti-clogging cleaning brush, and the anti-clogging cleaning brush is adapted to the storage tank.
[0010] Preferably, both the first and second screening screens are provided with screening grooves at their tops, and the bottom of the screening grooves is provided with through screening holes.

[0014] The advantages of this utility model are:
[0015] 1. This utility model operates by energizing a motor, which drives a threaded rod to rotate. The rotation of the threaded rod causes an internal threaded sliding plate to move under the limiting action of a limiting rod. The movement of the internal threaded sliding plate causes a slider to slide inside the through groove. The slider then drives two anti-clogging cleaning brushes to move out from the two storage slots to clean the first and second screening screens. This prevents the first and second screening screens from becoming clogged after prolonged use, which would affect the subsequent screening effect. Regular cleaning can also prevent clogging, thus enabling the screening machine to meet more usage needs and making it highly practical.

In conjunction with the screening screens 1 and 2 inside the screening box, the silicon material can be screened into three specifications. The screened silicon material can then be collected from the discharge pipes 1, 2, and 3 respectively. Thus, the screening effect of the screening machine is better due to the cooperation between the vibrating motor and the screening screens 1 and 2. Attached Figure Description

[0024] 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 protection scope of the present utility model.
[0025] Example 1
[0026] Please see Figure 1-4 As shown, an anti-clogging silicon material screening machine includes a support frame 12, and a screening box 1 is provided on the top of the support frame 12 through a support assembly;
[0027] The support assembly includes support plates 11 fixedly connected to the front and rear of the bottom of the screening box 1. Connecting rods 8 are fixedly connected through the left and right sides between the two support plates 11. Support blocks 9 are fixedly connected through the front and rear ends of the connecting rods 8. Support springs 10 are fixedly connected between the four support blocks 9 and the support frame 12. Two vibration motors 15 are fixedly installed at the bottom of the screening box 1 through the connecting blocks.
[0028] The screening box 1 has a screening trough inside. Screening mesh 16 and screening mesh 18 are fixedly connected to the upper and lower parts of the screening trough, respectively. Through-hole grooves 13 are opened on the upper and lower parts of the front surface of the screening trough. Collection grooves are opened on the upper and lower parts of the left side of the screening trough. A moving component 7 is provided on the front surface of the screening box 1. The left rear surface of the moving component 7 extends into the collection groove and is equipped with an anti-clogging cleaning brush 3. From top to bottom, discharge pipes 1, 2, and 3 are fixedly connected to the right side of the screening box 1. All three discharge pipes communicate with the interior of the screening trough. During operation, the bottom of the support frame 12 is first placed against a flat ground to ensure the screening machine is stable. The support frame 12 and the support component support the screening box 1. Then, the silicon material to be screened is placed into the screening box 1 through the feed hole 2. Screening is performed by vibration. When the machine 15 is powered on, the vibrating motor 15 operates, driving the screening box 1 to vibrate and screen. Combined with the screening screens 16 and 18 inside the screening box 1, the silicon material can be screened into three specifications. The screened silicon material can then be collected from the discharge pipes 4, 5, and 6 respectively. Simultaneously, the support spring 10 allows the screening box 1 to move during vibration, thus achieving a good screening effect through the combined screening of the vibrating motor 15, screening screens 16 and 18. Furthermore, the moving component 7 allows two anti-clogging cleaning brushes 3 to be moved from the two collection slots to clean screening screens 16 and 18, preventing clogging after prolonged use and ensuring optimal screening results. Regular cleaning also prevents clogging, allowing the screening machine to meet a wider range of application needs.
[0029] The moving component 7 includes a connecting plate 71 and a connecting plate 76 fixedly connected to the left and right sides of the screening box 1, respectively. A threaded rod 75 is rotatably connected between the connecting plate 71 and the connecting plate 76 via a bearing. A drive motor 72 is fixedly installed on the left side of the connecting plate 71, and the output end of the drive motor 72 is fixedly connected to the left end of the threaded rod 75. Limiting rods 74 are fixedly connected above and below the connecting plate 71 and the connecting plate 76. An internally threaded sliding plate 73 is threadedly connected to the left side of the outer surface of the threaded rod 75. The limiting rod 74 passes through the internally threaded sliding plate 73 and is slidably connected to the internally threaded sliding plate 73. A slider 77 is fixedly connected above and below the rear surface of the internally threaded sliding plate 73. The surface of the through groove 13 is located inside the receiving groove. The slider 77 is fixedly connected to the anti-clogging cleaning brush 3. During operation, the motor is powered on, and the motor drives the threaded rod 75 to rotate. The rotation of the threaded rod 75 drives the internal threaded sliding plate 73 to move under the limiting action of the limiting rod 74. The movement of the internal threaded sliding plate 73 drives the slider 77 to slide inside the through groove 13. Then, the slider 77 can drive the two anti-clogging cleaning brushes 3 to move out from the two receiving grooves to clean the screening screen 16 and screening screen 2 18. This prevents the screening screen 16 and screening screen 2 18 from clogging after long-term use, which would affect the subsequent screening effect. Regular cleaning can also be performed to avoid clogging, so that the screening machine can meet more usage needs and has strong practicality.
[0030] Limiting grooves 17 are provided above and below the rear surface of the screening tank. Limiting blocks 19 are slidably connected inside the limiting grooves 17. The limiting blocks 19 are fixedly connected to the anti-clogging cleaning brush 3. The anti-clogging cleaning brush 3 is adapted to the storage tank. During operation, the movement of the anti-clogging cleaning brush 3 is limited by the sliding of the limiting blocks 19 inside the limiting grooves 17, making the movement of the anti-clogging cleaning brush 3 more stable.
[0031] Both the first screening mesh 16 and the second screening mesh 18 are provided with screening grooves at the top, and the bottom of the screening grooves is provided with through screening holes. The size of the screening holes of the first screening mesh 16 is smaller than that of the screening holes of the second screening mesh 18. During operation, the silicon material can be screened into three specifications by screening the first screening mesh 16 and the second screening mesh 18 with different hole sizes.
[0032] The bottom of the anti-clogging cleaning brush 3 mentioned above is on the same horizontal plane as the lower surface of the screening groove of screening screen 16, and the bottom of the anti-clogging cleaning brush 3 mentioned below is on the same horizontal plane as the lower surface of the screening groove of screening screen 2 18. During operation, the two anti-clogging cleaning brushes 3 can clean screening screen 16 and screening screen 2 18 when they move, thereby avoiding clogging of screening screen 16 and screening screen 2 18.
[0033] A sealing gasket 14 is inserted inside the through groove 13. The sealing gasket 14 is made of rubber. During operation, the rubber sealing gasket 14 is inserted into the through groove 13 to seal the through groove 13 and prevent the silicon material from leaking out of the through groove 13 during screening. When it is necessary to clean the screening screen 16 and the screening screen 18, the sealing gasket 14 can be removed.
[0034] Example 2
[0035] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, a feed hopper 20 is fixedly installed on the top left side of the screening box 1, and the inside of the feed hopper 20 is connected to the inside of the feed hole 2; during operation, the silicon material that is easy to screen through the feed hopper 20 passes through the feed hole 2 and enters the screening box 1 for screening.
