Description

Technical Field

[0001] This invention relates to the field of silica sol processing technology, specifically to a raw material impurity removal device for silica sol processing. Background Technology

[0002] Silica sol is a milky-white colloidal solution formed by uniformly dispersing nano-silica particles in water. Due to its nanoparticles, high specific surface area, and chemical reactivity, silica sol plays an irreplaceable role in many industrial fields such as precision casting, coatings and paints, papermaking, textiles, and chemical mechanical polishing. During the processing of silica sol, it is necessary to remove solid insoluble impurities or metal ion impurities to improve the product quality of silica sol.

[0003] Most existing impurity removal equipment filters silica sol raw materials through screens. During use, the screen holes are easily clogged by impurities in the silica sol, reducing filtration efficiency. Furthermore, some impurities adhere to the inner wall of the screen, making them difficult to clean and affecting the continuous use of the screen. Manually cleaning clogged screens is not only time-consuming and labor-intensive, but also affects the progress of the impurity removal process. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a raw material impurity removal device for silica sol processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A raw material impurity removal device for silica sol processing includes a support frame.

[0015] like Figure 1 - Figure 5As shown, the present invention provides a raw material impurity removal device for silica sol processing, comprising a support frame 1, with a first vertical plate 2 and a second vertical plate 14 fixedly connected to the top two sides of the support frame 1 respectively. An annular groove 3 is provided on one side of both the first vertical plate 2 and the second vertical plate 14, and the two sets of annular grooves 3 are arranged opposite to each other. A rotating ring 4 is rotatably connected inside each set of annular grooves 3, and a sieve cylinder 5 is fixedly connected between the two sets of rotating rings 4. A toothed ring 6 is fixedly connected to the outer surface of the rotating ring 4 on the first vertical plate 2. The sieve cylinder 5 has multiple sets of sieve holes 7, and a cleaning mechanism 8 is provided on the first vertical plate 2, located inside the sieve cylinder 5. A striking component 9 is provided between the vertical plates 14. The first vertical plate 2 is provided with a driving mechanism 10 for driving the toothed ring 6, the cleaning mechanism 8 and the striking component 9. The second vertical plate 14 is provided with a feed chute 13. The driving mechanism 10 can drive the toothed ring 6, the cleaning mechanism 8 and the striking component 9 to move simultaneously, so that the screen cylinder 5 rotates as a whole. With the help of the striking component 9, the screen holes 7 can be effectively prevented from being blocked by impurities. At the same time, during the rotation of the screen cylinder 5, the cleaning mechanism 8 can clean the impurities in the screen cylinder 5 without manual cleaning, saving time and effort, and preventing impurities from adhering and affecting the continuous filtration and impurity removal operation of the screen cylinder 5, thus ensuring the efficiency of filtration and impurity removal.

[0016] The drive mechanism 10 includes a connecting frame 101, a first rotating rod 102, and a second rotating rod 103. Both the first rotating rod 102 and the second rotating rod 103 are rotatably connected to one side of the first upright plate 2. The connecting frame 101 is fixedly connected to the first upright plate 2. A drive motor 104 is fixedly mounted on the connecting frame 101. The drive end of the drive motor 104 is fixedly connected to a first rotating shaft 105 via a coupling. The other end of the first rotating shaft 105 extends into a corresponding annular groove 3 and is fixedly connected to a first gear 106. The first gear 106 meshes with a gear ring 6. First synchronous pulleys 107 are fixedly connected to the outer surfaces of both the first rotating rod 102 and the first rotating shaft 105. A first synchronous belt 108 is drively connected to the outer surfaces of the two sets of first synchronous pulleys 107. The first rotating rod 102 is fixedly connected to the striking assembly 9. The second rotating rod 102... The outer surfaces of the first rotating shaft 105 and the first rotating shaft 105 are fixedly connected with second synchronous pulleys 109. The outer surfaces of the two sets of second synchronous pulleys 109 are connected by a second synchronous belt 110. The second rotating rod 103 is fixedly connected to the cleaning mechanism 8. The drive motor 104 is started, and the drive motor 104 drives the first rotating shaft 105 to rotate. When the first rotating shaft 105 rotates, it drives the gear ring 6 to rotate through the first gear 106, which in turn drives the rotating ring 4 and the screen cylinder 5 to rotate as a whole between the first vertical plate 2 and the second vertical plate 14. This causes the silica sol raw material to be centrifugally screened in the screen cylinder 5 as the screen cylinder 5 rotates. The raw material that meets the requirements is discharged through the screen hole 7, and the impurities are trapped inside the screen cylinder 5. The rotation of the first rotating shaft 105 also drives the first rotating rod 102 and the second rotating rod 103 to rotate, thereby driving the cleaning mechanism 8 and the knocking assembly 9.

[0017] The striking component 9 includes a second rotating shaft 91 rotatably connected between the first vertical plate 2 and the second vertical plate 14. The second rotating shaft 91 is located above the screen cylinder 5. Multiple sets of rubber rods 92 are fixedly connected to the outer surface of the second rotating shaft 91. When the rubber rods 92 rotate, they all contact the screen cylinder 5. One side of the second rotating shaft 91 passes through the first vertical plate 2 and is fixedly connected to the drive mechanism 10. When the first rotating shaft 105 rotates, it drives the first rotating rod 102 to rotate through the first synchronous belt 108, which in turn drives the second rotating shaft 91 to rotate. The second rotating shaft 91 drives the multiple sets of rubber rods 92 on its surface to rotate, continuously striking the rotating screen cylinder 5, causing the screen cylinder 5 to vibrate, preventing impurities from clogging the screen holes 7, and ensuring the efficiency of screening and impurity removal.

[0018] The cleaning mechanism 8 includes a mounting frame 81 fixedly connected to the first vertical plate 2. A reciprocating screw 82 is rotatably connected inside the mounting frame 81. A guide rod 83 is fixedly connected inside the mounting frame 81. A guide block 84 is slidably connected to the outer surface of the guide rod 83. A slider 85 is threadedly connected to the outer surface of the reciprocating screw 82. The slider 85 is fixedly connected to the guide block 84. A connecting rod 86 is fixedly connected to the bottom of the slider 85. A push plate 87 for cleaning the screen cylinder 5 is fixedly connected to the bottom of the connecting rod 86. The push plate 87 has an arc-shaped structure. A third rotating shaft 88 is rotatably connected to one side of the mounting frame 81. The two ends of the third rotating shaft 88 are fixedly connected to the reciprocating screw 82 and the drive mechanism 10, respectively. The first vertical plate 2 and the second vertical plate... A discharge trough 11 is provided on one side of the screen cylinder 5. A baffle 12 is hinged to the top side of the discharge trough 11 through a hinge. The first rotating shaft 105 drives the second rotating rod 103 to rotate through the second synchronous belt 110. The second rotating rod 103 drives the reciprocating screw 82 to rotate through the third rotating shaft 88. Under the limiting and guiding action of the guide rod 83 and the guide block 84, the slider 85 drives the connecting rod 86 and the push plate 87 to reciprocate along the reciprocating screw 82. The arc-shaped push plate 87 moves along the inner wall of the screen cylinder 5. The push plate 87 pushes the impurities to move towards the discharge trough 11. The impurities push the baffle 12 and are discharged from the discharge trough 11, completing the automatic cleaning of impurities without the need for manual cleaning, ensuring that the screen cylinder 5 can continuously perform filtration and impurity removal operations.

[0019] Push blocks 89 are fixedly connected to both sides of the push plate 87; the push blocks 89 facilitate the pushing of the baffle 12.

[0020] Working principle: In use, the silica sol raw material to be impurities removed is injected into the screen cylinder 5 through the feed chute 13 on the second vertical plate 14. The drive motor 104 is started, which drives the first rotating shaft 105 to rotate. When the first rotating shaft 105 rotates, it drives the gear ring 6 to rotate through the first gear 106, which in turn drives the rotating ring 4 and the screen cylinder 5 to rotate as a whole between the first vertical plate 2 and the second vertical plate 14. This causes the silica sol raw material to be centrifugally screened inside the screen cylinder 5 as the screen cylinder 5 rotates. The raw material that meets the requirements is discharged through the screen holes 7, while impurities are trapped inside the screen cylinder 5. At the same time as the first rotating shaft 105 rotates, it drives the first rotating rod 102 to rotate through the first synchronous belt 108, which in turn drives the second rotating shaft 91 to rotate. The second rotating shaft 91 drives the multiple sets of rubber on the surface. The rotating rod 92 continuously strikes the rotating screen cylinder 5, causing the screen cylinder 5 to vibrate, preventing impurities from clogging the screen holes 7 and ensuring the efficiency of screening and impurity removal. At the same time, the first rotating shaft 105 drives the second rotating rod 103 to rotate through the second synchronous belt 110. The second rotating rod 103 drives the reciprocating screw 82 to rotate through the third rotating shaft 88. Under the limiting and guiding action of the guide rod 83 and the guide block 84, the slider 85 drives the connecting rod 86 and the push plate 87 to reciprocate along the reciprocating screw 82. The arc-shaped push plate 87 moves along the inner wall of the screen cylinder 5, and the push plate 87 pushes the impurities to move towards the discharge chute 11. The impurities push the baffle 12 and are discharged from the discharge chute 11, completing the automatic cleaning of impurities without the need for manual cleaning, ensuring that the screen cylinder 5 can continuously perform filtration and impurity removal operations.
