Description

Technical Field

[0001] This utility model relates to the field of white fused alumina production technology, specifically to a multi-stage sieving device for white fused alumina refining. Background Technology

[0002] White fused alumina is a hard material primarily composed of aluminum oxide, typically exceeding 98% and sometimes reaching over 99%, while also containing small amounts of iron oxide and silicon oxide. White fused alumina is usually white or off-white in color, with a dense crystalline structure, and is characterized by high hardness, high wear resistance, good chemical stability, and thermal stability. Its hardness is second only to diamond and sapphire, reaching 9.0 on the Mohs scale, making it one of the most commonly used high-hardness abrasives in industry. Currently, the processing of white fused alumina requires multiple rounds of fine screening to obtain finished products that meet factory production needs.

[0003] The existing technology has the following problems:

[0004] In existing technologies, multi-stage sieving devices for white fused alumina refining use vibrating motors to vibrate the device and sieve it through sieve plates. During the vibrating sieving process, white fused alumina powder or particles may splash, polluting the air environment and causing some impact on workers. It also results in waste of the splashed white fused alumina powder or particles. In addition, the sieving components in existing multi-stage sieving devices for white fused alumina refining are fixed, leaving a large amount of residue on the surface of the sieve plates after use, making them difficult to clean. Furthermore, it is difficult to replace damaged sieve plates.

[0005] Therefore, we need a multi-stage sieving device for white corundum refining to solve the above problems. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1: As Figures 1 to 5 As shown, this utility model provides a multi-stage sieving device for refining white fused alumina, including a sieving cylinder 1. A cylinder body 5 is slidably connected to the lower outer surface of the sieving cylinder 1, and a cylinder cover 2 is threadedly connected to the upper inner wall of the sieving cylinder 1. The threaded connection between the cylinder cover 2 and the sieving cylinder 1 facilitates opening or closing, and further prevents the possibility of white fused alumina splashing during processing. A feed inlet is provided on the left side of the upper surface of the cylinder cover 2, and a square tube 3 is fixedly connected to the inner wall of the feed inlet. The design of the square tube 3 and the feed inlet facilitates the entry of white fused alumina into the sieving cylinder 1 for sieving. A discharge pipe 4 is provided on the left side of the outer surface of the sieving cylinder 1, and two discharge pipes 4 are provided on the upper and lower right sides of the outer surface of the sieving cylinder 1. The different positions of the three discharge pipes 4 facilitate the separate discharge of different specifications of white fused alumina after processing and sieving. A vibration motor 6 is fixedly connected to the bottom of the sieving cylinder 1. The use of the vibration motor 6 facilitates the vibration of the sieving cylinder 1, making... The sieving cylinder 1 slides up and down inside the cylinder 5. Several springs 7 are fixedly connected to the bottom of the sieving cylinder 1 in a circular array. The lower ends of the springs 7 are fixedly connected to the bottom of the inner wall of the cylinder 5. Through the elastic setting of the springs 7 and the cooperation of the vibration motor 6, the shaking performance of the sieving cylinder 1 is improved, and the efficiency of sieving white corundum powder is accelerated. Three sieving plates 12 are set on the outer surface of the connecting component 11. The three sieving plates 12 are in an inclined state. The setting of the three sieving plates 12 facilitates the sieving of white corundum of different specifications. At the same time, the inclined sieving plates 12 facilitate the discharge of the sieved white corundum. The outer surface of the middle sieving plate 12 is mirrored with the upper and lower sieving plates 12 respectively. The mesh size of the three sieving plates 12 is different. A rhomboid sleeve 13 is fixedly connected to the middle of the lower surface of the inner wall of the sieving cylinder 1. The setting of the rhomboid sleeve 13 facilitates the subsequent insertion of the rhomboid block 115 and prevents rotation.

[0027] Example 2: Figures 1 to 5As shown, the outer surface of the square tube 3 is provided with a protective structure, which includes a protective sleeve 31. The protective sleeve 31 covers the square tube 3, preventing the white corundum from moving out of the inside of the square tube 3 during processing. Connecting plates 33 are fixedly connected to the front and rear sides of the lower surface of the protective sleeve 31. The connecting plates 33 are movably connected to the slider 36, allowing the protective sleeve 31 to be rotated and opened. Grooves 32 are formed on the front and rear sides of the inner wall of the protective sleeve 31, facilitating sliding up and down on the outer surface of the mounting plate 34. Mounting plates 34 are fixedly connected to the front and rear sides of the outer surface of the square tube 3. The outer surface of the mounting plate 34 corresponds to and slidably connects to the grooves 32. A sliding groove 35 is formed on the outer surface of the mounting plate 34, and a slider 36 is slidably connected inside the sliding groove 35. The sliding groove 35, slider 36, and connecting plate 33 facilitate the up and down sliding of the protective sleeve 31, enabling subsequent... To open or close the slide block 36, an insert block 37 is provided on the outer surface of the slide block 36. A blocking block 38 is provided on the left side of the insert block 37. The blocking block 38 and the insert block 37 are designed to limit the position of the protective sleeve 31 after it is closed. The rear side of the blocking block 38 is fixedly connected to the surface of the mounting plate 34. The outer surface of the slide block 36 is movably connected to the surface of the connecting plate 33. A T-shaped slider 361 is fixedly connected to the right side of the outer surface of the slide block 36. A T-shaped groove is provided on the right rear side of the insert block 37. The outer surface of the T-shaped slider 361 is slidably connected to the inside of the T-shaped groove. The T-shaped slider 361 and the T-shaped groove are designed to allow the insert block 37 to move only left and right, preventing the slide block 36 and the insert block 37 from separating. A slot is provided on the left side of the insert block 37. The inside of the slot is magnetically fixedly connected to the outer surface of the blocking block 38. The magnetic attraction between the two helps to limit the position of the inserted block 37 after it has moved. In addition, the blocking block 38 is magnetic, and the insert block 37 is a metal block.

[0028] Example 3: Figures 1 to 5As shown, a connecting assembly 11 is provided in the middle of the inner wall of the screening cylinder 1. The connecting assembly 11 includes four columns 111. The arrangement of the four columns 111 facilitates the loading and unloading of each column 111, and also facilitates the loading and unloading of each screening plate 12. Clamping blocks 112 are fixedly connected to the upper and lower outer surfaces of adjacent columns 111. The clamping blocks 112 tighten the columns 111 when the cylinder cover 2 is closed, so that the adjacent clamping blocks 112 clamp and fix the screening plate 12 respectively. The outer surfaces of the four columns 111 are inserted into the interior of the screening plate 12. The insertion method facilitates the loading, unloading and replacement of the screening plate 12, and also facilitates the cleaning of residual white corundum. The outer surfaces of adjacent clamping blocks 112 are clamped and fixed to the upper and lower surfaces of the screening plate 12 respectively. The lower end of the lower column 111 is fixedly connected to a rhombus-shaped block 115. The outer surface of the rhombus-shaped block 115 is inserted into the interior of the rhombus-shaped sleeve 13. This structure prevents the connecting component 11 from rotating. The upper end of the upper column 111 is fixedly connected to a rubber block 114. The upper surface of the rubber block 114 overlaps and presses against the lower surface of the cylinder cover 2. This structure facilitates the tightening and limiting of the four columns 111 after connection, so that the four columns 111 form a whole. The lower end of the upper column 111 and the lower ends of three of the columns 111 are provided with rhombus-shaped insertion holes. The upper ends of the three columns 111 are fixedly connected to a rhombus-shaped block 113. The outer surface of the rhombus-shaped block 113 is inserted into the interior of the rhombus-shaped insertion hole. The rhombus-shaped block 113 and the rhombus-shaped insertion block facilitate the connection and installation of two adjacent columns 111.

[0029] Working principle: During use, the vibration motor 6 and the spring 7 work together to make the screening cylinder 1 shake up and down, and the three screening plates 12 of different specifications facilitate the screening of white fused alumina, so that the screened white fused alumina is discharged from the discharge pipe 4 at different positions.

[0030] After the white fused alumina enters the sieving cylinder 1, the worker moves the protective sleeve 31 upward, causing the slider 36 to slide inside the groove 35. When it slides to the appropriate position, the protective sleeve 31 is rotated so that it is directly above the square tube 3. Then, the protective sleeve 31 is moved downward so that the inside of the protective sleeve 31 is inserted into the outer surface of the square tube 3. The worker then moves the insert block 37 so that the slot in the insert block 37 contacts the blocking block 38, thereby magnetically fixing it and preventing the possibility of powder splashing during the processing of white fused alumina.

[0031] After use, the worker opens the cylinder cover 2 by turning it counterclockwise. Then, the worker moves the upper column 111 by moving the rubber block 114 upwards, separating the sieve plate 12. By repeating the above steps, the adjacent columns 111 are loosened and removed, which facilitates the removal of the other two sieve plates 12. This makes it easier to install, remove and replace the sieve plates 12, and also makes it easier to clean the residual white corundum on the surface of the sieve plates 12 after disassembly.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
