Description

Technical Field

[0001] This utility model belongs to the field of silicon carbide processing technology, specifically, it relates to a water washing and purification device for processing silicon carbide raw materials. Background Technology

[0002] Water washing and purification is a crucial step in the processing of silicon carbide raw materials. Its purpose is to remove impurities from the raw materials in order to meet the stringent requirements of different fields for the purity and quality of silicon carbide.

[0003] Currently, traditional silicon carbide water washing and purification devices have gradually revealed many problems in practical applications. They have low efficiency in removing impurities from the surface of silicon carbide particles. Because they rely solely on simple water rinsing or static filtration, many impurities attached to the particle surface are difficult to be effectively washed away, resulting in the purified silicon carbide raw material failing to meet high purity standards. This severely limits its application in fields with stringent purity requirements, such as semiconductors and high-end abrasives. In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water washing and purification device for silicon carbide raw material processing that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A water washing and purification device for processing silicon carbide raw materials includes a housing, and further includes: a washing chamber, a filtering chamber, and a water storage chamber arranged in sequence and connected to the housing, wherein the housing has a feeding port communicating with the washing chamber; a support frame fixedly installed in the washing chamber; a filter plate slidably connected to the support frame, wherein a guide rod is slidably connected to the support frame, the guide rod is fixedly connected to the filter plate, and a limit block is fixedly installed at the end of the guide rod away from the filter plate; a spring sleeved on the guide rod and located between the lower end face of the filter plate and the upper end face of the limit block; a rotating shaft rotatably connected to the inner wall of the washing chamber; a cam fixedly installed on the rotating shaft and used to push the filter plate to slide up and down reciprocally in the washing chamber; and a rinsing mechanism arranged in the washing chamber and used to rinse the silicon carbide raw materials added to the washing chamber.

[0007] For rinsing silicon carbide raw materials added to the cleaning chamber, preferably, the rinsing mechanism includes a movable block and a hollow cavity formed in the movable block. The lower end face of the movable block has a water spray hole that communicates with the hollow cavity. A water supply pump is fixedly installed on the side wall of the housing. The input end of the water supply pump is connected to the water storage chamber, and the output end is connected to the hollow cavity through a liquid delivery pipe. The movable block is set in the cleaning chamber and is located above the filter plate.

[0008] To drive the movable sleeve to move the movable block back and forth within the cleaning chamber, a lead screw is rotatably connected within the cleaning chamber, a slide rod is fixedly connected to the inner wall of the cleaning chamber, a movable sleeve is slidably connected to the slide rod, the movable sleeve is threadedly connected to the lead screw, the movable sleeve and the movable block are integrally formed, a motor is fixedly installed on the side wall of the housing, and the lead screw is fixedly connected to the output end of the motor.

[0009] To further drive the rotating shaft to rotate, pulleys are fixedly installed at one end of the lead screw and the rotating shaft that penetrates the side wall of the housing, and the two pulleys are connected by a belt.

[0010] For use in filtering, recycling and reusing used water, preferably, it also includes multiple activated carbon filter cartridges, all of which are inserted into the filter chamber.

[0011] To facilitate the removal of the cleaned silicon carbide raw material from the cleaning chamber, preferably, the housing is provided with a discharge port that communicates with the cleaning chamber, the lower end face of the discharge port is parallel to the upper end face of the filter plate, and a sealing plate for closing the discharge port is detachably connected to the housing.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0014] This invention allows the filter plate to slide up and down repeatedly. The raw material is subjected to vertical vibration and water flow on the filter plate, which not only allows small particles of impurities to enter the filter chamber, but also makes the raw material constantly tumble, increasing the contact opportunities with water and the rinsing mechanism, thus improving the cleaning effect and purification quality. It also makes the water spray coverage wider, avoids cleaning dead corners, and ensures that all parts of the raw material are fully rinsed, thereby improving the uniformity and thoroughness of purification.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Example 1:

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6A water washing and purification device for processing silicon carbide raw materials includes a housing 1, and further includes: a washing chamber 101, a filtering chamber 102, and a water storage chamber 103 arranged in sequence and connected to each other in the housing 1, wherein the housing 1 has a feeding port connected to the washing chamber 101; a support frame 2, fixedly installed in the washing chamber 101; and a filter plate 201 slidably connected to the support frame 2, wherein a guide rod 202 is slidably connected to the support frame 2, the guide rod 202 is fixedly connected to the filter plate 201, and the guide rod 202 is located away from the filter plate 201. A limiting block 204 is fixedly installed at one end of the filter plate 201; a spring 203 is sleeved on the guide rod 202 and is located between the lower end face of the filter plate 201 and the upper end face of the limiting block 204; a rotating shaft 5 is rotatably connected to the inner wall of the cleaning chamber 101; a cam 501 is fixedly installed on the rotating shaft 5 and is used to push the filter plate 201 to slide up and down reciprocally in the cleaning chamber 101; a rinsing mechanism is set in the cleaning chamber 101 and is used to rinse the silicon carbide raw material added to the cleaning chamber 101.

[0025] The rinsing mechanism includes a movable block 3 and a hollow cavity opened in the movable block 3. The lower end face of the movable block 3 is provided with a water spray hole 301 that communicates with the hollow cavity. A water supply pump 302 is fixedly installed on the side wall of the housing 1. The input end of the water supply pump 302 is connected to the water storage chamber 103, and the output end is connected to the hollow cavity through the liquid delivery pipe 303. The movable block 3 is set in the cleaning chamber 101 and is located above the filter plate 201.

[0026] A lead screw 4 is rotatably connected inside the cleaning chamber 101. A slide rod 401 is fixedly connected to the inner wall of the cleaning chamber 101. A movable sleeve 402 is slidably connected to the slide rod 401. The movable sleeve 402 is threadedly connected to the lead screw 4. The movable sleeve 402 and the movable block 3 are integrally formed. A motor 403 is fixedly installed on the side wall of the housing 1. The lead screw 4 is fixedly connected to the output end of the motor 403.

[0027] First, the silicon carbide raw material to be cleaned and stored is added into the cleaning chamber 101 through the feeding port. When it is necessary to rinse the silicon carbide raw material in the cleaning chamber 101, the water supply pump 302 is started. The water in the water storage chamber 103 enters the hollow cavity of the moving block 3 through the liquid delivery pipe 303 under the action of the pump, and then sprays out from the water spray hole 301 to form a high-pressure water flow to rinse the raw material. The impact force of the water flow can wash away the impurities on the surface of the silicon carbide particles, thereby improving the purity of the silicon carbide raw material.

[0028] When cleaning and purifying silicon carbide raw materials, the motor 403 is started, and the motor 403 drives the lead screw 4 to rotate. Due to the threaded engagement between the moving sleeve 402 and the lead screw 4 and the guiding effect of the slide bar 401, the moving sleeve 402 will move linearly on the lead screw 4, thereby driving the moving block 3 to reciprocate horizontally in the cleaning chamber 101. This allows the water sprayed from the water spray hole 301 of the moving block 3 to cover the silicon carbide raw materials at different positions in the cleaning chamber 101, thereby achieving a comprehensive rinsing of the raw materials and avoiding cleaning dead corners, thus improving the purification quality of the silicon carbide raw materials.

[0029] Example 2:

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A water washing and purification device for processing silicon carbide raw materials is basically the same as that in Example 1. Furthermore, the lead screw 4 and the rotating shaft 5 are both fixedly installed with pulleys at one end of the side wall of the housing 1, and the two pulleys are connected by a belt 502.

[0031] During the rotation of the lead screw 4, the rotating shaft 5 can also be driven to rotate via the belt 502. The rotating shaft 5 drives the cam 501 to rotate synchronously. When the cam 501 rotates, it abuts against the filter plate 201, causing the filter plate 201 to move upward under the push of the cam 501 and compress the spring 203. Then, when the cam 501 separates from the filter plate 201, the compressed spring 203 generates a thrust, pushing the filter plate 201 to move downward and reset in the cleaning chamber 101. This process is repeated, causing the filter plate 201 to slide up and down on the support frame 2. During this process, the silicon carbide raw material is subjected to up and down vibration and water flow on the filter plate 201, causing smaller impurity particles to enter the filter chamber 102 through the pores of the filter plate 201, while relatively larger silicon carbide particles are blocked on the filter plate 201. At the same time, due to the up and down movement of the filter plate 201, the raw material will continuously turn over in the cleaning chamber 101, increasing the contact opportunity with water and the rinsing mechanism, and further improving the cleaning effect.

[0032] It should be noted that the infusion tube 303 is a stretchable and retractable hose, so the infusion tube 303 will not interfere with the left and right reciprocating movement of the moving block 3 in the cleaning chamber 101.

[0033] Example 3:

[0034] Reference Figure 3 A water washing and purification device for processing silicon carbide raw materials is basically the same as that in Example 1. Furthermore, it also includes multiple activated carbon filter elements 7, all of which are inserted into the filter chamber 102.

[0035] When water containing impurities enters the filter chamber 102 from the cleaning chamber 101 through the filter plate 201, the water flows through the activated carbon filter element 7. Because the activated carbon filter element 7 has a rich pore structure, it can adsorb organic matter, pigments and some residual fine impurity particles in the water, thus purifying the water quality. Then, the water filtered by the activated carbon filter element 7 enters the water storage chamber 103, thereby realizing the recycling of water, ensuring the quality of the circulating water, reducing the secondary pollution of silicon carbide raw materials by harmful substances in the water, and helping to improve the purification quality of silicon carbide.

[0036] It should be noted that since the activated carbon filter element 7 is connected to the filter chamber 102 by a plug-in method, when it is necessary to clean the activated carbon filter element 7, it is easy for the staff to remove the activated carbon filter element 7 from the filter chamber 102 for cleaning. At the same time, when the activated carbon filter element 7 is damaged after long-term use, it is also easy to disassemble and replace it.

[0037] Example 4:

[0038] Reference Figure 1 , Figure 3 A water washing and purification device for silicon carbide raw material processing is basically the same as that in Example 1. Furthermore, the box 1 is provided with a discharge port that communicates with the washing chamber 101. The lower end face of the discharge port is parallel to the upper end face of the filter plate 201. A sealing plate 6 for closing the discharge port is detachably connected to the box 1.

[0039] The sealing plate 6 is detachably connected to the housing 1 by multiple fixing bolts 601;

[0040] After the silicon carbide raw material is cleaned in the cleaning chamber 101, unscrew the fixing bolt 601 and remove the sealing plate 6. At this time, since the lower end face of the discharge port is parallel to the upper end face of the filter plate 201, it is convenient for the staff to take out the cleaned silicon carbide raw material from the cleaning chamber 101.

[0041] During the cleaning process, the sealing plate 6 is tightly fixed to the box 1 by the fixing bolts 601 to ensure the sealing of the cleaning chamber 101 and to ensure the normal operation of the water washing and purification process.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
