[0002] Silicon carbide micro powder is a fine particulate material made of silicon carbide (SiC). Due to its excellent physical and chemical properties, it is widely used in many industries.

[0003] To improve the precision of silicon carbide micro powder, it undergoes a washing and screening process. The main purpose of washing and screening silicon carbide micro powder is to remove impurities, such as mineral impurities, metal oxides, and other impurities, in order to improve its purity and performance. The washing and screening process can improve the physicochemical properties of silicon carbide, making it more suitable for specific industrial applications.

[0004] When washing silicon carbide micro powder, a certain amount of silicon carbide micro powder is usually poured into a sedimentation tank, and then the silicon carbide micro powder is stirred to remove impurities floating on the water surface. Subsequently, the precipitated silicon carbide micro powder is dried. However, this washing method not only cannot continuously wash silicon carbide micro powder, but also requires a period of time for the silicon carbide micro powder to settle, which reduces the washing efficiency of silicon carbide micro powder, thus having certain defects.

[0015] The present invention also provides an operation method for an integrated device for drying and classifying silicon carbide micro powder, including the following specific steps: Step 1: During the washing and screening of silicon carbide micro powder, the high-level water tower injects water into the washing and screening cylinder through water pipes. When the water inside the washing and screening cylinder flows out through the waste discharge frame, the water inside the washing and screening cylinder pushes the sealing shaft upward through the float, so that the through hole on the sealing shaft is misaligned with the water inlet hole on the sealing block. The sealing shaft seals the water inlet hole, and the water inlet pipe stops injecting water into the washing and screening cylinder. As the waste discharge frame discharges water and scum, the water level inside the washing and screening cylinder drops. The float drives the sealing shaft downward, so that the through hole on the sealing shaft connects with the water inlet hole on the sealing block. The water pipe replenishes water into the washing and screening cylinder. Step 2: When silicon carbide micro powder enters the washing and screening cylinder through the feed hopper, the servo motor drives the brush plate and scraper assembly to rotate clockwise through the transmission shaft disc, agitating the silicon carbide micro powder. The brush plate cleans the silicon carbide micro powder on the filter screen, causing the silicon carbide micro powder to settle inside the washing and screening cylinder through the filter screen. The scraper assembly gathers the silicon carbide micro powder, and the impurities floating on the water surface are discharged through the waste discharge frame. The auger conveyor transports the silicon carbide micro powder settled at the bottom of the washing and screening cylinder to the dryer for drying. Step 3: When scraping impurities off the filter screen, close the solenoid valve on the water pipe to stop the water supply to the washing cylinder. Release the locking rod from locking the limit plate, allowing the waste discharge frame to slide down the connecting track via the sealing plate. This will bring the bottom of the inner wall of the waste discharge frame to the same horizontal level as the bottom of the inner wall of the waste discharge hole on one side of the washing cylinder. The bottom of the inner wall of the waste discharge frame, the bottom of the inner wall of the waste discharge hole, and the top of the filter screen will then be on the same plane. One end of the outer wall of the locking rod will engage with the locking groove at the bottom of the connecting track, locking the waste discharge frame in place. The servo motor will then drive the brush plate and scraper assembly to rotate counterclockwise via the transmission shaft disc. This will cause the impurities filtered on the filter screen to slide to the side of the filter screen under the action of the inclined scraper, and then be discharged through the waste discharge hole and the waste discharge frame.

[0016] The technical effects and advantages of this invention are as follows: (1) The present invention utilizes a combination of a washing and screening mechanism, an auger conveyor and a dryer. The washing and screening mechanism can continuously wash and filter silicon carbide micro powder, and then the auger conveyor transports the precipitated silicon carbide micro powder to the dryer for drying, thereby improving the working efficiency of washing and drying silicon carbide micro powder and improving the production efficiency of silicon carbide micro powder. (2) The present invention utilizes a combination of washing and screening cylinder, water replenishment component, feed hopper, filter component and waste discharge component. The water replenishment component can replenish water according to the water level inside the washing and screening cylinder, so that the floating impurities mixed in the silicon carbide micro powder are discharged through the waste discharge component, so that silicon carbide micro powder can be continuously added to the washing and screening cylinder, thereby continuously washing and screening the silicon carbide micro powder. (3) The present invention utilizes the combination of the filter component and the waste discharge component. When the drive shaft disk drives the scraper component to rotate clockwise, the scraper component can gather the silicon carbide micro powder on the filter screen, reducing the amount of silicon carbide micro powder discharged through the waste discharge frame. When the drive shaft disk drives the scraper component to rotate counterclockwise and lowers the height of the waste discharge frame, the scraper component can centrifugally scrape the impurities on the filter screen and discharge them.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides, for example Figure 1-9 The device shown is an integrated device for drying and classifying silicon carbide micro powder.

[0021] Example 1 The system includes a washing and screening mechanism 1, an auger conveyor 2, and a dryer 3. The washing and screening mechanism 1 includes a washing and screening cylinder 11, a water replenishment component 12, a feed hopper 13, a filter component 14, and a waste discharge component 15. The water replenishment component 12 is installed on the washing and screening cylinder 11 and is used to replenish water to the washing and screening cylinder 11, maintaining the water flow inside the washing and screening cylinder 11 at a specified height. The feed hopper 13 is installed on the top of the washing and screening cylinder 11. The filter component 14 is installed on the washing and screening cylinder 11 and is used to wash and filter silicon carbide micro powder. The waste discharge component 15 is installed on one side of the washing and screening cylinder 11. Thus, silicon carbide micro powder is conveyed to the inside of the washing and screening cylinder 11 through the feed hopper 13. Under the washing of the filter component 14 and the water flow, the silicon carbide micro powder settles to the bottom of the inner cavity of the washing and screening cylinder 11. Floating impurities are discharged through the waste discharge component 15. The feed end of the auger conveyor 2 is connected to the bottom of the washing cylinder 11. The auger conveyor 2 is used to transport the precipitated silicon carbide micro powder. The height of the discharge port of the auger conveyor 2 is much higher than the height of the water level inside the washing cylinder 11, thereby reducing the moisture trapped inside the silicon carbide micro powder when the auger conveyor 2 transports it. The dryer 3 is connected to the discharge end of the auger conveyor 2. The dryer 3 is used to dry the silicon carbide micro powder transported by the auger conveyor 2. After the auger conveyor 2 transports a certain amount of silicon carbide micro powder into the dryer 3, the dryer 3 dries a batch of silicon carbide micro powder and then dries the subsequent batches of silicon carbide micro powder. The dryer 3 is a known existing device and will not be described in detail here.

[0022] Specifically, the filter assembly 14 includes a filter screen 141, a servo motor 142, a drive shaft disk 143, a brush plate 144, and a scraper assembly 145. The filter screen 141 is installed inside the washing cylinder 11 and can filter silicon carbide micro powder of acceptable coarseness. The servo motor 142 is installed at the top of the washing cylinder 11, and the drive shaft disk 143 is driven and installed at the output end of the servo motor 142. The brush plate 144 is fixedly installed at the bottom of the drive shaft disk 143 and is used to clean the silicon carbide micro powder on the filter screen 141, reducing the possibility of silicon carbide micro powder clogging on the filter screen 141. The scraper assembly 145... The 45 is installed at an angle at the bottom of the drive shaft disk 143. The drive shaft disk 143 drives the scraper assembly 145 to rotate clockwise to gather the silicon carbide micro powder on the filter screen 141, thereby reducing the amount of silicon carbide micro powder discharged from the waste discharge assembly 15 along with floating impurities. The servo motor 142 drives the brush plate 144 and the scraper assembly 145 to rotate clockwise at a slow speed through the drive shaft disk 143, thereby avoiding the situation where the silicon carbide micro powder cannot settle due to rotation. The drive shaft disk 143 drives the scraper assembly 145 to rotate counterclockwise to centrifugally discharge the impurities on the filter screen 141, so as to facilitate the subsequent cleaning of the impurities on the filter screen 141.

[0023] Furthermore, the scraping assembly 145 includes a connecting housing 1451, a scraper 1452, a fixing member 1454, a fixing plate 1455, a guide rod 1456, a limiting spring 1457, and a locking plate 1458. The connecting housing 1451 is fixedly connected to the bottom of the drive shaft disk 143 in an inclined state. The scraper 1452 is slidably sleeved inside the connecting housing 1451. An inclined slope is provided on one side of the bottom of the scraper 1452. A rubber plate 1453 is fixedly connected to the bottom of the scraper 1452. Thus, when the connecting housing 1451 and the scraper 1452 rotate clockwise, the filter... The silicon carbide micropowder on the mesh 141 can pass through the inclined bottom of the scraper 1452, and the rubber plate 1453 can prevent the scraper 1452 from scratching the filter mesh 141. The fixing member 1454 is fixedly connected to the top of the scraper 1452. The fixing member 1454 is installed inside the connecting housing 1451. The side of the fixing member 1454 is U-shaped, and the front of the fixing member 1454 is door-shaped. The fixing plate 1455 is fixedly connected to the inside of the connecting housing 1451. The outer wall of the fixing plate 1455 is slidably engaged with the fixing member 1454. The fixing member 1454 is as follows: Figure 7 As shown, the fixing plate 1455 can horizontally limit the fixing member 1454, and the fixing member 1454 can vertically slide and separate from the fixing plate 1455. The bottom of the guide rod 1456 is fixedly connected to the fixing member 1454, and the outer wall of the guide rod 1456 is slidably inserted and sleeved with the fixing plate 1455. The limiting spring 1457 is slidably sleeved on the outside of the guide rod 1456. The limiting spring 1457 is located on the side of the fixing plate 1455 facing the scraper 1452. The limiting spring 1457 can give the scraper 1452 an elastic force towards the filter screen 141. The bottom of the scraper 1452 is subjected to the vertical squeezing and pushing force of the silicon carbide micro powder, which can make the scraper 1452 slide upward. The locking plate 145... The outer wall of plate 8 is slidably inserted into the connecting housing 1451, and the outer wall of locking plate 1458 is slidably snapped into the fixing member 1454. Locking plate 1458 is located on top of fixing plate 1455. The end of locking plate 1458 is fixedly connected to a fixing block that is fixedly connected to the connecting housing 1451. The fixing block is fixedly connected to the connecting housing 1451 by bolts. Locking plate 1458 can snap and limit the height of fixing member 1454, preventing the bottom of scraper 1452 from directly squeezing filter screen 141 under the action of limiting spring 1457. By pulling out locking plate 1458, scraper 1452 and multiple fixing members 1454 can be directly removed from inside connecting housing 1451.

[0024] Example 2 Based on Example 1, the water replenishment component 12 includes a high-level water tower 121, a fixed housing 122, a water pipe 123, and a sealing block 124. The high-level water tower 121 is located on the back of the washing cylinder 11. The fixed housing 122 is fixedly connected to one side of the washing cylinder 11. The water pipe 123 is installed between the high-level water tower 121 and the fixed housing 122. A solenoid valve is installed on the water pipe 123. The sealing block 124 is fixedly connected to the top of the inner cavity of the fixed housing 122. Water inlet holes 125 are provided on one side of the sealing block 124, one side of the fixed housing 122, and one side of the washing cylinder 11. The inner cavity of the water pipe 123 is interconnected with the inner cavity of the washing cylinder 11 through the water inlet holes 125. Thus, the water flow inside the high-level water tower 121 can enter the interior of the washing cylinder 11 through the water pipe 123 and the water inlet holes 125 under the action of gravity, providing water flow for the washing of silicon carbide micro powder.

[0025] In particular, the water replenishment assembly 12 also includes a sealing shaft 126, a through hole 127, a shaft seal 128, a float 129, a hole 1210, and a mesh plate 1211. The bottom of the sealing block 124 has a shaft hole that matches the sealing shaft 126. The through hole 127 is opened on one side of the sealing shaft 126. The sealing shaft 126 slides up and down relative to the sealing block 124, so that the through hole 127 aligns with the water inlet hole 125. The water pipe 123 delivers water into the washing cylinder 11. The through hole 127 and the water inlet hole 125 are misaligned. The sealing shaft 126 blocks and seals the water inlet hole 125, stopping the water flow into the washing cylinder 11, thus achieving automatic water replenishment. The shaft seal 128 is installed at the bottom of the sealing block 124 and is sleeved on the outside of the sealing shaft 126. The float 129 is fixedly connected to the bottom of the sealing shaft 126 and is slidably sleeved inside the fixed housing 122. The hole 1210 is opened on the opposite side of the fixed housing 122 and the washing cylinder 11. The bottom of the inner cavity of the fixed housing 122 is connected to the inner cavity of the washing cylinder 11 through the hole 1210. The screen plate 1211 is installed inside the hole 1210. When the water flow inside the washing cylinder 11 supports the sealing shaft 126, and the water flow inside the washing cylinder 11 is lower than the inner cavity of the waste discharge frame 151, the float 129 drives the sealing shaft 126 to descend. The through hole 127 on the sealing shaft 126 is aligned with the water inlet hole 125. Water is injected into the washing cylinder 11 by the water pipe 123. When the water flow inside the washing cylinder 11 is higher than the bottom of the inner wall of the waste discharge frame 151, that is, when the water flow inside the washing cylinder 11 rises, the float 129 drives the sealing shaft 126 to rise and fall, causing the through hole 127 on the sealing shaft 126 to be misaligned with the water inlet hole 125. The water pipe 123 then stops injecting water into the washing cylinder 11.

[0026] Furthermore, the waste discharge assembly 15 includes a waste discharge frame 151, a connecting rail 152, a sealing plate 153, and a waste discharge hole 154. The waste discharge frame 151 is disposed on one side of the washing cylinder 11. The connecting rail 152 is fixedly connected to the outside of the washing cylinder 11. The sealing plate 153 is fixedly connected to one end of the waste discharge frame 151. A discharge hole corresponding to the waste discharge frame 151 is opened on one side of the sealing plate 153. The outer side of the sealing plate 153 is slidably engaged with the connecting rail 152. A sealing gasket is fixedly connected to the side of the sealing plate 153 facing the washing cylinder 11. The sealing gasket can improve the sealing performance between the sealing plate 153 and the washing cylinder 11. The waste discharge hole 154 is opened on one side of the washing cylinder 11, so that impurities floating inside the washing cylinder 11 can be discharged through the waste discharge frame 151. The bottom of the inner wall of the waste discharge hole 154 is on the same plane as the top of the filter screen 141, which facilitates the discharge of impurities on the filter screen 141.

[0027] Specifically, the waste discharge assembly 15 also includes a limiting plate 155, a connecting plate 156, a locking rod 157, a locking groove 158, a fixing sleeve 159, a fixing rod 1510, a limiting block 1511, a positioning spring 1512, and a handle 1513. The limiting plate 155 is fixedly connected to the side of the waste discharge frame 151. The connecting plate 156 is located on one side of the limiting plate 155. One end of the locking rod 157 is fixedly connected to the connecting plate 156. The outer wall of the locking rod 157 is slidably inserted into the limiting plate 155. Two locking grooves 158 are opened on one side of the connecting rail 152, and the locking rod 157 is engaged with the locking grooves 158 at different positions. The waste discharge frame 151 is in different working states. In state one, floating impurities and water flow are discharged. In state two, impurities on the filter screen 141 are discharged. One end of the outer wall of the locking rod 157 is slidably engaged with the inner cavity of the locking groove 158. The fixing sleeve 159 is fixedly connected to the connecting plate 1511. On one side of 6, one end of the fixing rod 1510 is fixedly connected to the limiting plate 155. The outer wall of the fixing rod 1510 is slidably inserted into the connecting plate 156. The limiting block 1511 is fixedly connected to the end of the fixing rod 1510. The limiting block 1511 is slidably sleeved inside the fixing sleeve 159. The positioning spring 1512 is slidably sleeved outside the fixing rod 1510. The positioning spring 1512 is located between the limiting block 1511 and the connecting plate 156. The positioning spring 1512 can give the connecting plate 156 an elastic compressive force, so that the connecting plate 156 drives the locking rod 157 to maintain a stable locking state with the locking groove 158 on the connecting rail 152. The end of the handle 1513 is fixedly connected to the fixing sleeve 159. The handle 1513 can drive the connecting plate 156 away from the limiting plate 155 through the fixing sleeve 159, so that the locking rod 157 is separated from the locking groove 158 on the connecting rail 152.

[0028] The present invention also provides an operation method for an integrated device for drying and classifying silicon carbide micro powder, including the following specific steps: Step 1: During the washing and screening of silicon carbide micro powder, the high-level water tower 121 injects water into the washing and screening cylinder 11 through the water pipe 123. When the water inside the washing and screening cylinder 11 flows out through the waste discharge frame 151, the water inside the washing and screening cylinder 11 pushes the sealing shaft 126 upward through the float 129, so that the through hole 127 on the sealing shaft 126 is misaligned with the water inlet hole 125 on the sealing block 124. The sealing shaft 126 seals the water inlet hole 125, and the water pipe 123 stops injecting water into the washing and screening cylinder 11. As the waste discharge frame 151 discharges water and scum, the water level inside the washing and screening cylinder 11 drops. The float 129 drives the sealing shaft 126 to drop, so that the through hole 127 on the sealing shaft 126 connects with the water inlet hole 125 on the sealing block 124. The water pipe 123 replenishes water into the washing and screening cylinder 11. Step 2: When silicon carbide micro powder enters the washing cylinder 11 through the feed hopper 13, the servo motor 142 drives the brush plate 144 and scraper assembly 145 to rotate clockwise through the transmission shaft disc 143, agitating the silicon carbide micro powder. The brush plate 144 cleans the silicon carbide micro powder on the filter screen 141, causing the silicon carbide micro powder to settle inside the washing cylinder 11 through the filter screen 141. The scraper assembly 145 gathers the silicon carbide micro powder, and the impurities floating on the water surface are discharged through the waste discharge frame 151. The screw conveyor 2 transports the silicon carbide micro powder settled at the bottom of the washing cylinder 11 to the dryer 3 for drying. Step 3: When scraping impurities off the filter screen 141, close the solenoid valve on the water pipe 123 to stop the water supply to the washing cylinder 11. Release the locking rod 157 from locking the limit plate 155, allowing the waste discharge frame 151 to slide down the connecting track 152 via the sealing plate 153. This brings the bottom of the inner wall of the waste discharge frame 151 to the same horizontal level as the bottom of the inner wall of the waste discharge hole 154 on one side of the washing cylinder 11. This ensures that the bottom of the inner wall of the waste discharge frame 151 and the bottom of the inner wall of the waste discharge hole 154 are aligned.
