[0023] See also Figure 1-Figure 5 The high-purity alumina fragment cleaning device of this embodiment can classify the alumina fragments that need to be cleaned according to their sizes, and can also clean the fragments of different sizes in different ways, so that the impurities on the fragments are cleaned more cleanly and the quality of the fragments after cleaning is guaranteed. In this embodiment, it mainly includes a shell 1, and the shell 1 is mounted on a bracket 2 arranged outside it. A top cover 8 is fixedly arranged on the top of the shell 1. A feed port 9 is opened on the top side of the shell 1, and the alumina fragments are poured through the feed port 9. A water injection pipe 10 is fixedly arranged on the top cover 8, and water is added to the interior through the water injection pipe 10 to facilitate subsequent cleaning operations. A cleaning chamber 3 is opened inside the shell 1, and a cleaning ring 6 is vertically and coaxially arranged inside the cleaning chamber 3. A stirring chamber 4 connected to the cleaning chamber 3 is opened at the bottom of the shell 1. A classification plate 5 located between the cleaning chamber 3 and the stirring chamber 4 is fixedly arranged horizontally inside the shell 1. A plurality of filter holes 22 are opened on the classification plate 5. The aluminum oxide fragments entering the cleaning chamber 3 are filtered through the classification plate 5, so that smaller fragments enter the stirring chamber 4.
[0024] The bottom of the cleaning chamber 3 is an inverted cone structure inclined toward the middle. It is convenient to classify fragments of different sizes. The bottom of the mixing chamber 4 is detachably provided with a sealing cover 18, and the middle part of the sealing cover 18 is an inverted cone structure inclined toward the middle. The fragments can be gathered, which is convenient for the subsequent discharge of the cleaned fragments. A discharge port 19 is provided in the middle position of the bottom of the sealing cover 18, and a baffle 20 for covering the discharge port 19 is detachably provided at the bottom end of the sealing cover 18. It is convenient for the subsequent discharge of the fragments. A suction pipe 21 extending into the mixing chamber 4 is vertically provided at the top of the mixing chamber 4. The impurities cleaned off the fragments can be removed through the suction pipe 21 to avoid affecting the cleaning of the fragments when there are too many impurities.
[0025] To avoid blockage during classification, which would affect the classification of broken pieces. Figure 2-Figure 4In this embodiment, a liftable anti-blocking plate 23 is provided below the classification plate 5, and a plurality of through slots 24 are provided on the anti-blocking plate 23. Anti-blocking columns 25 that can respectively penetrate the corresponding filter holes 22 are vertically fixedly provided at the top of the anti-blocking plate 23. A second electric push rod 26 is fixedly provided at the top of the mixing chamber 4, and the output end of the second electric push rod 26 extends into the mixing chamber 4 and its end is fixedly provided with the anti-blocking plate 23. When cleaning the fragments, the second electric push rod 26 is controlled to work so that the anti-blocking plate 23 moves up and down, thereby circulating the anti-blocking column 25 in and out of the filter hole 22 to prevent the fragments from blocking the filter hole 22. The blocked part of the classification plate 5 is unblocked to ensure that smaller fragments can pass normally.
[0026] To achieve the cleaning of the fragments. Figure 2 , Figure 3 and Figure 5 In this embodiment, an operating shell 11 is vertically fixedly arranged at the middle of the top of the top cover 8, and a cleaning mechanism 7 coaxial with the cleaning ring 6 and penetrating the cleaning chamber 3 and the mixing chamber 4 is vertically arranged inside the housing 1. The cleaning mechanism 7 includes a rotating shaft 71 vertically rotatingly arranged at the middle of the top of the operating shell 11, and the rotating shaft 71 penetrates the cleaning chamber 3 and extends into the mixing chamber 4. A spiral auger 72 is fixedly arranged in the middle of the rotating shaft 71, and the spiral auger 72 is located above the classification plate 5 and inside the cleaning ring 6. The fragments are moved upward in the cleaning ring 6 by the spiral auger 72. A brush 73 is arranged on the rotating shaft 71 above the spiral auger 72, and the brush 73 is located inside the cleaning ring 6. The fragments moving upward in the cleaning ring 6 are cleaned by the brush 73. A rotating paddle 74 is fixedly arranged at the end of the rotating shaft 71 in the mixing chamber 4. Smaller fragments are stirred to achieve the cleaning of fragment impurities. A motor 75 for driving the rotating shaft 71 to rotate is fixedly arranged at the middle of the top of the operating shell 11. A plurality of water exchange grooves 76 are provided on the side of the cleaning ring 6.
[0027] During cleaning, the motor 75 is controlled to work, so that the fragments are moved from bottom to top inside the cleaning ring 6 through the spiral auger 72, and the fragments outside the cleaning ring 6 are moved from top to bottom, forming a cycle. When the fragments moving upward pass through the brush 73 area, the fragments are scraped off by the rotating brush 73. In this process, the rising and cleaning fragments can be rinsed through the water changing tank 76, and the scraped impurities can be washed away to avoid the impurities not being washed away in time and affecting the subsequent cleaning. At the same time, the stirring paddle rotates in the stirring chamber 4, stirring the smaller fragments in the stirring chamber 4, causing the fragments to produce relative friction, thereby cleaning the impurities on the fragments.
[0028] In order to realize the discharge of the cleaned fragments. In this embodiment, see Figure 1-Figure 3 and Figure 5, a discharging barrel 12 that can be raised and lowered is coaxially arranged inside the operating shell 11, and the bottom end of the discharging barrel 12 can abut against the cleaning ring 6. During cleaning, a first electric push rod 13 is fixedly arranged on the top cover 8 on the side of the operating shell 11, and the discharging barrel 12 is fixedly arranged with the output end of the first electric push rod 13 through a sliding plate 14 fixedly arranged on one side of its top, and a sliding groove 15 for the sliding plate 14 to be raised and lowered is provided on the operating shell 11. A discharge port 16 is provided on the side of the operating shell 11, and a discharge port 17 corresponding to the position of the discharge port 16 is provided on the discharging barrel 12. When the fragments are being cleaned, the discharging barrel 12 is located at the top under the action of the first electric push rod 13, so as to avoid the discharging barrel 12 from obstructing the fragments being cleaned. After the cleaning is completed, the first electric push rod 13 works to push the sliding plate 14 to move downward in the sliding groove 15, thereby moving the discharging barrel 12 downward until it abuts against the top of the cleaning ring 6. At this time, the discharge port 16 and the discharge port 17 are located at the same place. The spiral auger 72 continues to rotate, and the fragments moving upward are discharged from the discharge port 16 through the discharge barrel 12. When most of the fragments are discharged, new fragments that need to be cleaned are added for cleaning again. After the alumina fragments are cleaned, the equipment can be disassembled, all the fragments are discharged, and the internal parts are checked to avoid affecting the subsequent cleaning.
[0029] The method of using the high-purity alumina fragment cleaning device of the utility model is as follows: first, pour the alumina fragments into the cleaning chamber 3 from the feed port 9. After a certain amount is poured in, water is added to the inside through the water injection pipe 10. Then the motor 75 is controlled to work and the rotating shaft 71 is rotated. At this time, the spiral auger 72 moves the fragments from the bottom to the top inside the cleaning ring 6, and the fragments outside the cleaning ring 6 move from the top to the bottom, forming a cycle. When the fragments moving upward pass through the brush 73 area, the fragments are scraped off by the rotating brush 73. In this process, the fragments that are rising and cleaning can be rinsed through the water exchange tank 76, and the scraped impurities can be washed away to avoid the impurities not being washed away in time and affecting the subsequent cleaning. At the same time, the stirring paddle rotates in the stirring chamber 4, stirring the smaller fragments in the stirring chamber 4, causing the fragments to produce relative friction, thereby cleaning the impurities on the fragments.
[0030] During this process, the alumina fragments are filtered through the filter holes 22 of the classification plate 5, so that smaller fragments enter the mixing chamber 4. The second electric push rod 26 is controlled to work to move the anti-blocking plate 23 up and down, so that the anti-blocking column 25 is circulated in and out of the filter hole 22 to prevent the fragments from blocking the filter hole 22. The blocked part of the classification plate 5 is cleared to ensure that smaller fragments can pass normally.
[0031] During the cleaning process, the impurities removed from the fragments can be removed through the pumping pipe 21 to avoid the fragments being cleaned up when there are too many impurities. At this time, the discharge barrel 12 is located at the top under the action of the first electric push rod 13 to avoid the discharge barrel 12 from hindering the fragments being cleaned.
[0032] After the cleaning is completed, the first electric push rod 13 works to push the sliding plate 14 downward in the sliding groove 15, thereby moving the discharge barrel 12 downward until it abuts against the top of the cleaning ring 6. At this time, the discharge port 16 and the discharge port 17 are located at the same place. The spiral auger 72 continues to rotate, and the fragments that move upward at this time are discharged outward from the discharge port 16 through the discharge barrel 12. After most of the fragments are discharged, new fragments that need to be cleaned continue to be added for cleaning again. After the alumina fragments are cleaned, all the liquid can be pumped out through the suction pipe 21, and the baffle 20 can be removed. At this time, the smaller fragments are discharged from the discharge port 19. Finally, the equipment can be disassembled, all the fragments can be discharged, and the internal parts can be inspected to avoid affecting the subsequent cleaning.
