Abstract
Description
Technical Field
[0001] This utility model relates to the field of monocrystalline silicon processing technology, and in particular to a novel silicon material acid washing and purification device. Background Technology
[0002] When cleaning monocrystalline silicon, it is first immersed in acid. The flowing acid carries impurities out through openings in the container wall, thus achieving the removal of impurities from the monocrystalline silicon. Traditional cleaning and purification devices mostly assist in the flow of acid, but they lack the ability to move the monocrystalline silicon, resulting in generally low processing efficiency. The cleaning efficiency is even worse when silicon materials are piled together. Therefore, a novel silicon acid washing and purification device is proposed. Utility Model Content
[0003] The present invention aims to solve the technical problems existing in the prior art and provide a novel silicon material acid washing and purification device.
[0004] To achieve the above objectives, this utility model adopts the following technical solution, including a cleaning box, a guide pipe connected to an external pipe installed at the bottom of the cleaning box, an installation compartment inside the left side of the cleaning box, a drive motor installed inside the installation compartment, a freely flip-up movable cover plate on the top of the installation compartment, a drive shaft inside the cleaning box, the drive shaft being linked with the output shaft of the drive motor inside the installation compartment, a rotating structure outside the drive shaft, four equidistantly arranged loading slots on the surface of the rotating structure, four storage compartments for storing silicon material installed outside the rotating structure, and a sleeve shaft at the center of the rotating structure, the rotating structure being fitted onto the outside of the drive shaft for synchronous rotation.
[0005] Furthermore, four mutually spaced positioning holes are provided on both sides of the rotating structure, and the positioning holes are connected to the interior of the corresponding loading slots. Positioning slots corresponding to the positioning holes are provided on both sides of the storage compartment.
[0006] Furthermore, the surface of the storage compartment is covered with a sieve for filtering, and the surface of the storage compartment has two feeding openings located far apart from each other.
[0007] Furthermore, an adjusting arc plate is installed inside the feeding opening, and two mutually spaced connecting slots are opened on the upper surface inside the feeding opening. Two access blocks of the size corresponding to the inside of the connecting slots are provided at one end of the adjusting arc plate.
[0008] Furthermore, a limiting protrusion is provided at the center of the inner bottom surface of the feeding opening, and a docking slot corresponding to the size of the limiting protrusion is provided on the top of the adjusting arc plate. After the adjusting arc plate is installed, the limiting protrusion is engaged with the inside of the docking slot.
[0009] This utility model provides a novel acid washing and purification device for silicon materials, which has the following beneficial effects:
[0010] 1. A novel silicon material acid washing and purification device, comprising a synchronously rotating structure, wherein the overall shape of the storage chamber installed outside the rotating structure is completely fitted with the internal shape of the loading tank, and an adjusting arc plate is movably installed inside the two feeding openings. After the external silicon material is fed into the storage chamber by opening the adjusting arc plate, the adjusting arc plate is closed. The docking groove at the bottom of the adjusting arc plate is fitted onto the outside of the limiting protrusion. The adjusting arc plate is kept closed by inserting fixing bolts into the pre-reserved insertion holes inside the docking groove and the limiting protrusion. During the rotation and cleaning process of the storage chamber, the material inside the storage chamber will be agitated and come into full contact with the acid. Compared with existing cleaning devices, this device can drive the silicon material and acid to mix more thoroughly and has the ability to move the silicon material, which can effectively speed up the acid washing process.
[0011] 2. A novel silicon material pickling and purification device, featuring easily removable storage bins. After the storage bins are placed inside the loading tank, the positioning slots on both sides of the storage bins will align with the positioning holes. The fixing bolts are inserted into the positioning holes and rotated into the positioning slots to lock the storage bin's position. Once all the material is inside the storage bins, the device is started. During operation, the drive shaft pulls the rotating structure to rotate the four storage bins, causing the material to roll. After the pickling process is complete, the entire storage bin can be lifted out using the two adjustment handles on the outside. By positioning the entire storage bin perpendicular to the ground, the material inside can be discharged through the feeding opening on one side. The material removal process is very convenient.

[0019] A novel silicon material acid washing and purification device, such as Figures 1 to 4 As shown, the device includes a cleaning tank 1, a guide pipe 2 connected to an external pipe installed at the bottom of the cleaning tank 1, an installation chamber 3 inside the left side of the cleaning tank 1, a drive motor installed inside the installation chamber 3, a freely flip-up movable cover plate 4 on the top of the installation chamber 3, a drive shaft 10 inside the cleaning tank 1, the drive shaft 10 being linked with the output shaft of the drive motor inside the installation chamber 3, a rotating structure 5 outside the drive shaft 10, four equidistant loading slots 7 on the surface of the rotating structure 5, four storage compartments 6 for storing silicon material installed outside the rotating structure 5, and a rotating shaft 9 at the center of the rotating structure 5, the rotating structure 5 being fitted onto the outside of the drive shaft 10 for synchronous rotation.
[0020] The rotating structure 5 has four mutually spaced positioning holes 8 on both sides of its surface. The positioning holes 8 are connected to the interior of the corresponding loading slots 7. The storage compartments 6 have positioning slots 16 on both sides of their surface that correspond to the positioning holes 8. After the storage compartments 6 are inserted into the loading slots 7, the position of the positioning slots 16 will correspond to the position of the positioning holes 8. The position of the storage compartments 6 can be fixed by inserting the external bolts through the positioning holes 8 into the positioning slots 16 and rotating them. After the four storage compartments 6 are installed, they form a complete cylindrical structure.
[0021] The surface of the storage compartment 6 is covered with a screen for filtering. There are two feeding openings 12 on the surface of the storage compartment 6 that are far apart from each other. An adjusting arc plate 13 is installed inside the feeding opening 12. There are two connecting slots 17 that are far apart from each other on the upper surface inside the feeding opening 12. After the adjusting arc plate 13 is installed, it can be flipped. After the adjusting arc plate 13 is pulled open, the material can be put into the storage compartment 6.
[0022] A limiting protrusion 14 is provided at the center of the bottom surface inside the feeding opening 12. The top of the adjusting arc plate 13 is provided with a docking slot 15 corresponding to the size of the limiting protrusion 14. After the adjusting arc plate 13 is combined, the limiting protrusion 14 is inserted into the docking slot 15. The fixing bolt is rotated and fixed by passing through the docking slot 15 and the slot inside the limiting protrusion 14. After the adjusting arc plate 13 is combined, the material is stored in the storage bin 6. When the equipment is running, the storage bin 6 rotates with the rotating structure 5, causing the material inside the storage bin 6 to flip. During the pickling process, the silicon material flips over and comes into full contact with the solution, which greatly improves the pickling efficiency of the silicon material.
[0023] The working principle of this utility model:
[0024] By setting a synchronously rotating rotating structure 5, the overall shape of the storage bin 6 installed outside the rotating structure 5 is completely fitted with the internal shape of the loading groove 7. The adjusting arc plate 13 is movably installed inside the two feeding openings 12. After opening the adjusting arc plate 13 and feeding the external silicon material into the storage bin 6, the adjusting arc plate 13 is closed. The docking hole groove 15 at the bottom of the adjusting arc plate 13 is fitted onto the outside of the limiting protrusion 14. After inserting the fixing bolt into the reserved insertion hole inside the docking hole groove 15 and the limiting protrusion 14, the adjusting arc plate 13 can be kept in the closed state. During the rotation and cleaning process of the storage bin 6, the material inside the storage bin 6 will turn over and come into full contact with the acid. Compared with the existing cleaning device, this device can drive the silicon material and acid to mix more thoroughly and has the ability to drive the silicon material to move. It can effectively speed up the acid washing efficiency during the acid washing process.
[0025] With the storage compartment 6 designed for easy removal, after the storage compartment 6 is placed inside the loading tank 7, the positioning slots 16 on both sides of the storage compartment 6 will correspond to the positions of the positioning holes 8. After the fixing bolts are inserted into the positioning holes 8 and rotated into the positioning slots 16, the position of the storage compartment 6 is locked. After all the material is put into the storage compartment 6, the equipment is started. When the equipment is running, the drive shaft 10 pulls the rotating structure 5 to drive the four storage compartments 6 to rotate. During the rotation, the material is rolled. After the material pickling is completed, the entire storage compartment 6 can be lifted out through the two adjusting handles 11 on the outside of the storage compartment 6. The entire storage compartment 6 can be perpendicular to the ground, and the material inside the storage compartment 6 can be discharged through the feeding opening 12 on one side. The material retrieval process is also very convenient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
