Due to the different sources of recycled silicon materials, the shapes of the recycled silicon materials are irregular, and there are a large number of defects such as gaps and holes in the silicon materials. As a result, a large amount of cleaning liquid remains in the cleaned silicon materials and cannot be effectively removed, seriously affecting the quality of the recycled silicon materials. Traditional cleaning methods have many problems. Cleaning efficiency is generally low, and it takes a long time to remove impurities from the silicon materials. Moreover, during the cleaning process, the liquid flow is easily turbulent, and high-speed liquid flow may cause impact on the silicon materials, causing silicon materials to stack up and affecting the cleaning effect.

The side wall of the positioning plate 55 is fixedly connected with a horizontal flow cleaning device 56. The fixing device 1 is the basic component that connects the entire device. At the same time, the reflux groove 12, connecting groove 14, anti-overflow groove 16, guide plate 15, connecting groove 17 and other structures in the fixed seat 11 are used in conjunction with each other. Among them, the connecting groove 17 is connected to the reflux groove 12 and the anti-overflow groove 16. This design is conducive to the circulation of cleaning liquid inside the cleaning device composed of the fixing device 1 and the splicing device 5, and the liquid extraction pipe 4 is connected to the liquid outlet device 2 through the reflux pump 3. The reflux pump 3 can extract the cleaning liquid for recycling.

[0027] The connecting groove 17 is connected to the reflux groove 12, the reflux groove 12 is connected to the anti-overflow groove 16, the side walls of the waterproof ring 53 and the side walls of the positioning plate 55 are slidingly connected to the side walls of the guide plate 15, the outer wall of the bottom of the guide plate 15 is slidingly connected to the outer wall of the top of the guide plate 54, and the inner wall of the fixing seat 11 is fixedly connected to the outer wall of the liquid extraction tube 4.

[0028] The horizontal flow cleaning device 56 includes a fixed box 561, the inner wall of the fixed box 561 is fixedly connected to the limit frame 562, the inner wall of the limit frame 562 is plugged with an anti-backflow device 563, the inner wall of the fixed box 561 is slidably connected to the placement frame 564, the side wall of the placement frame 564 is symmetrically provided with a water channel 565, the inner wall of the fixed box 561 is slidably connected to the pressure plate 566, the outer wall of the bottom of the pressure plate 566 contacts the outer wall of the top of the placement frame 564, and the outer wall of the fixed box 561 is connected to the fixed seat 1 through the insertion groove 18. 1 is plugged into the inner wall of the fixing box 561, and the side wall of the positioning plate 55 is fixedly connected. The fixing box 561 in the horizontal flow cleaning device 56 provides an installation position for other components, wherein the placement frame 564 is used to place the silicon material. When placed, the silicon material is flatly laid on the top of the bottom end of the placement frame 564. The water groove 565 on its side wall facilitates the circulation of the cleaning liquid, and the water groove 565 on one side is opposite to the connecting square tube 25. The fixing box 561 is positioned in the insertion groove 18 to stably wrap the liquid outlet position, so that the liquid flow is stably input.

[0029] The anti-backflow device 563 includes an insert block 5631. The outer wall of the insert block 5631 is plugged into the outer wall of the limit frame 562 through an anti-slip groove 5632. The anti-slip groove 5632 is provided on the outer wall of the insert block 5631. Auxiliary guide grooves 5633 are symmetrically provided on the inner wall of the insert block 5631. A corrugated groove 5634 is provided on the inner wall of the insert block 5631. A diverter column 5635 is fixedly connected to the inner wall of the insert block 5631. The auxiliary guide groove 5633, the corrugated groove 5634 and the diverter column 5635 are provided on the inner wall of the insert block 5631 to guide the water flow and prevent the backflow of the horizontal flow. The specific process is to form a Tesla valve through the corrugated groove 5634 and the diverter column 5635. Due to the Tesla valve structure, the cleaning fluid flows relatively smoothly in the forward direction, but is greatly hindered in the reverse flow, thereby preventing backflow. During forward flow, the fluid can flow relatively naturally along specific bends and branch paths in the channel of the Tesla valve. During reverse flow, the fluid needs to overcome complex bends, corners and mutual interference between fluids. When the fluid passes through the bends of the corrugated groove 5634, vortices and recirculation areas will be generated. These areas will hinder the reverse movement of the fluid, resulting in a significant increase in the resistance to reverse flow.

[0030] The liquid outlet device 2 includes a liquid inlet pipe 21, the inner wall of the liquid inlet pipe 21 is fixedly connected to a shunt pipe 22, the outer wall of the shunt pipe 22 is fixedly connected to a liquid storage box 23, the inner wall of the liquid storage box 23 is fixedly connected to a blocking rod 24, the inner wall of the liquid storage box 23 is fixedly connected to a connecting square tube 25, the outer wall of the liquid inlet pipe 21 is fixedly connected to the output end of the reflux pump 3, the outer wall of the connecting square tube 25 is fixedly connected to the inner wall of the fixing seat 11 through the connecting groove 14, the side wall outside the liquid storage box 23 is fixedly connected to the side wall inside the fixing seat 11, and under the pressure provided by the reflux pump 3, the liquid is cleared. After the washing liquid moves upward along the liquid inlet pipe 21, it reaches the position of the diversion pipe 22. Similarly, under the action of pressure, the washing liquid enters the diversion pipe 22 and is diverted into the liquid storage box 23. The blocking rods 24 in the liquid storage box 23 can play a certain diversion and buffering role. This is because the blocking rods 24 are arranged in a trapezoidal shape and the number decreases successively. This arrangement makes the number of blocking rods 24 close to the liquid inlet position of the diversion pipe 22 large, which can effectively buffer the high-speed liquid flow that has just entered, quickly reduce the liquid flow speed, avoid liquid flow turbulence, cause impact on the silicon material, and prevent silicon material stacking.

[0032] Working principle:

[0033] When in use, the fixing device 1 is the basic component that connects the entire device. At the same time, the reflux groove 12, connecting groove 14, anti-overflow groove 16, guide plate 15, connecting groove 17 and other structures in the fixing seat 11 are used in conjunction with each other. Among them, the connecting groove 17 is connected to the reflux groove 12 and the anti-overflow groove 16. This design is conducive to the circulation of the cleaning liquid inside the cleaning device composed of the fixing device 1 and the splicing device 5. The liquid extraction pipe 4 is connected to the liquid outlet device 2 through the reflux pump 3. The reflux pump 3 can extract the cleaning liquid for recycling. During the cleaning process, the cleaning liquid submerges the uppermost horizontal flow cleaning device 56, and the anti-overflow groove 16 is provided to prevent the cleaning liquid from overflowing from both sides of the fixing device 1.

[0034] During the liquid circulation process, the starting position of the cleaning liquid is at the liquid outlet device 2, and the liquid inlet pipe 21 receives the cleaning liquid output by the reflux pump 3. Under the pressure provided by the reflux pump 3, the cleaning liquid moves upward along the liquid inlet pipe 21 and reaches the position of the diverter pipe 22. Similarly, under the action of pressure, the cleaning liquid enters the diverter pipe 22 and is diverted to the liquid storage box 23. The blocking rod 24 in the liquid storage box 23 can play a certain role in guiding and buffering. This is because the blocking rods 24 are arranged in a trapezoidal shape and the number decreases in sequence. This arrangement makes the number of blocking rods 24 close to the liquid inlet position of the diverter pipe 22 large, which can effectively buffer the liquid just entering The high-speed liquid flow quickly reduces the liquid flow speed, avoids liquid flow turbulence, impacts the silicon material, and prevents silicon material from stacking. As the liquid flow advances toward the interior of the liquid storage box 23, the number of blocking rods 24 decreases, allowing the liquid flow to smoothly transition to the subsequent area, forming a relatively stable horizontal flow, thereby making the cleaning liquid evenly distributed in the liquid storage box 23, thereby reducing the degree of turbulence of the liquid flow when passing through the connecting square tube 25, making the cleaning process more efficient and safe, and also helping to improve the cleaning quality, thereby ensuring the stability of the multi-layer horizontal flow cleaning effect, so that the connecting square tube 25 stably transports the cleaning liquid to the horizontal flow cleaning device 56;

[0035] The positioning plate 55 above the guide plate 54 is connected to the horizontal flow cleaning device 56. The fixed box 561 in the horizontal flow cleaning device 56 provides an installation position for other components. The placement frame 564 is used to place the silicon material. When placing it, the silicon material is flat on the top of the bottom end of the placement frame 564. The water groove 565 on its side wall facilitates the circulation of the cleaning liquid, and the water groove 565 on one side is directly opposite the connecting square tube 25. The fixed box 561 is positioned in the plug-in slot 18 to stably wrap the liquid outlet position, so that the liquid flow is stably input and flows stably over the surface of the silicon material to perform horizontal cleaning on the silicon material. The setting of the pressure plate 566 ensures the fixation of the placement frame 564.

[0036] The insertion block 5631 of the anti-backflow device 563 is inserted with the limiting frame 562 through the anti-escape groove 5632 to ensure stable installation. The auxiliary flow guide groove 5633, the corrugated groove 5634 and the flow dividing column 5635 arranged on the inner wall of the insertion block 5631 are used to guide the water flow and prevent the horizontal flow from backflowing. The specific process forms a Tesla valve through the corrugated groove 5634 and the flow dividing column 5635. Since the structure of the Tesla valve makes the cleaning liquid relatively smooth in forward flow and is greatly hindered in reverse flow, the stability and unidirectionality of the horizontal cleaning are ensured. The smoothness of the Tesla valve in forward flow and the hindering in reverse flow are mainly based on its special geometric structure. In principle, in forward flow, the fluid can flow naturally along the specific curved and branched path in the channel of the Tesla valve, while in reverse flow, the fluid needs to overcome complex bends, corners and mutual interference between fluids. When the fluid passes through the bend of the corrugated groove 5634, eddy and backflow area are generated, which hinders the reverse movement of the fluid, resulting in increased resistance to reverse flow. Therefore, when the fluid flows in reverse, the corrugated structure causes the fluid to collide, turn and other complex flow changes, thereby hindering the reverse movement of the fluid and making the resistance to reverse flow much greater than the resistance to forward flow. When the fluid flows forward, the shape of the corrugated groove 5634 guides the fluid to flow forward, and the symmetrical auxiliary flow guide grooves 5633 on both sides can increase the water flow and make the cleaning liquid more evenly distributed. In the cleaning process, this structure can reduce the poor cleaning effect caused by turbulent liquid flow, ensure efficient multi-layer horizontal cleaning, reduce liquid energy loss, make the flow of the cleaning liquid more in line with the requirements of horizontal cleaning, and further improve the cleaning quality of the silicon material. Moreover, no additional power is needed to assist in preventing backflow, saving equipment operation cost.

[0037] The moving seat 51 of the split device 5 can slide on the outer wall of the fixed seat 11 of the fixed device 1. In actual use, the fixed seat 11 is fixed in position, the moving seat 51 is placed on the movable activity plate, and the force receiving groove 52 on the moving seat 51 receives the pushing force and pulling force for quickly disassembling and splitting the cleaning device. The waterproof ring 53 inside the moving seat 51 plays a waterproof role to prevent the cleaning liquid from overflowing the moving seat 51, and the flow guide plate 54 at the bottom of the waterproof ring 53 cooperates with the guide plate 15 to provide a flow channel for the flow of the cleaning liquid. At this time, the cleaning liquid flowing out of the anti-backflow device 563 enters the flow channel composed of the waterproof ring 53, the flow guide plate 54, the positioning plate 55, the guide plate 15, the fixed seat 11 and the fixed plate 131. Since backflow is prevented, after the cleaning liquid is discharged, it moves to both sides and finally passes through the flow control device 13 to enter the backflow groove 12 through the communication groove 17, completing the overall circulation of the cleaning liquid. Through the flow of the cleaning liquid, the cleaning process of the silicon material is accelerated, and the time required to clean the impurities inside the silicon material is reduced.

[0038] A flow control device 13 is provided to control the flow rate and circulation process of the cleaning liquid inside the cleaning device. The servo motor 132 of the flow control device 13 drives the worm 133 to rotate, and the worm 133 engages with the worm wheel 134, thereby rotating the internal threaded barrel 135. The internal threaded barrel 135 is threadedly connected to the threaded rod 136, thereby driving the valve 137 to slide in the positioning frame 138 to achieve control of the water level height.
