Technical Field
[0001] This utility model relates to the field of filtration technology, and in particular to a filtration device for silicon dioxide production. Background Technology
[0002] Silicon dioxide is a solid at room temperature. It is insoluble in water and acids, but soluble in hydrofluoric acid and hot concentrated phosphoric acid. It can react with molten alkalis. Silicon dioxide has a wide range of uses, mainly in the manufacture of glass, water glass, ceramics, enamel, refractory materials, aerogel felt, ferrosilicon, molding sand, elemental silicon, and cement.
[0003] In the production process of silica, it is often necessary to filter the prepared silica slurry to remove large particulate impurities. Over time, these impurities can clog the filter screen, affecting the filtration effect. Cleaning requires disassembling the filter screen for cleaning and then reinstalling it, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0026] A filtration device for silica production includes a box 1 with supporting feet 11 on all four sides, a sealing cover 2 on the top of the box 1, a feed inlet 21 on one side of the top of the sealing cover 2, a motor 24 on the top of the sealing cover 2, a filter box 3 rotatably connected to the bottom of the sealing cover 2, and the top of the filter box 3 connected to the drive shaft of the motor 24 via a connecting block.
[0027] The sealing cover 2 has a sliding groove 25 on the side away from the feed inlet 21. A cleaning plate 5 is slidably connected to the sliding groove 25. A cleaning brush 51 is provided on the side of the cleaning plate 5 near the filter box 3. An adjustment component 4 is provided on the top of the sealing cover 2 for adjusting the position of the cleaning plate 5. An inclined surface 12 is provided at the bottom of the inner cavity of the box body 1. A discharge port 8 is provided at the bottom of the box body 1. The outlet end of the discharge port 8 is connected to the inclined surface 12. A flow guide 7 is provided at the bottom of the inner cavity of the box body 1. Flow guide grooves are evenly distributed around the flow guide 7. A baffle structure 6 is provided on the top of the flow guide 7.
[0028] Silica slurry is added to the housing 1 through the inlet 21. The slurry enters the filter box 3 through the inlet 21. The motor 24 is started to drive the filter box 3 to rotate, which drives the liquid to quickly pass through the filter holes on the filter box 3 and enter the bottom of the housing 1, leaving impurities inside the filter box 3. The liquid flows through the inclined surface 12 and the guide 7, and is discharged outward from the discharge port 8 at the bottom. After all the liquid is discharged, the baffle structure 6 moves away from the filter box 3. The adjusting component 4 drives the cleaning plate 5 to move closer to the filter box 3. The motor 24 drives the filter box 3 to rotate. At the same time, the cleaning brush 51 cleans the filter holes on the filter box 3. The cleaning plate 5 can be equipped with a nozzle connected to a water source to clean the filter box 3, reducing the blockage of the filter holes on the filter box 3 by impurities, which would affect the subsequent filtration effect. Moreover, there is no need to remove the filter device afterward, saving time and effort, and realizing automatic cleaning of the filter box 3. The cleaned impurities are discharged downward from the installation point of the filter box 3 and the baffle structure 6 into the housing 1, and are discharged outward through the discharge port 8.
[0029] As a possible implementation of this solution, preferably, the filter box 3 is equipped with a stirring shaft 31 inside, and several sets of stirring rods 32 are staggered on the stirring shaft 31. When the motor 24 drives the filter box 3 to rotate, the stirring rods 32 rotate synchronously, breaking up the lumps in the slurry, accelerating the liquid to pass through the filter holes on the filter box 3, enter the bottom of the box body 1, and be discharged from the discharge port 8 under the action of the guide 7, leaving the filtered impurities in the filter box 3, thus realizing the automatic filtration function.
[0030] As a possible implementation of this solution, preferably, the baffle structure 6 includes an electric push rod 61 disposed on the top of the guide member 7. The electric push rod 61 is disposed inside the waterproof cover. The drive end of the electric push rod 61 is provided with a baffle seat 62. The top of the baffle seat 62 passes through the filter box 3. The top of the baffle seat 62 is arc-shaped. The outer wall of the baffle seat 62 is provided with a limiting plate 63.
[0031] The guide component 7 is used to guide the liquid flow to the discharge port 8. When the filter box 3 is in operation, the electric push rod 61 on the guide component 7 pushes the baffle seat 62 to move upward until the limiting plate 63 abuts against the bottom of the filter box 3. At this time, the baffle seat 62 passes through the filter box 3, so that the bottom of the filter box 3 forms a closed structure to prevent the leakage of unfiltered silica slurry. After filtration is completed, the electric push rod 61 drives the baffle seat 62 to descend, and the solid impurities in the filter box 3 are discharged along the inclined surface 12 towards the discharge port 8.
[0032] As a possible implementation of this solution, preferably, the adjustment component 4 includes a movable plate 41 and a fixed plate 42. The movable plate 41 is slidably connected to the sealing cover 2, the fixed plate 42 is fixed to one side of the top of the sealing cover 2, the movable plate 41 is fixedly connected to the top of the cleaning plate 5, and a lead screw 43 is connected between the movable plate 41 and the fixed plate 42. One end of the lead screw 43 passes through the fixed plate 42 and is provided with a control handle 44 for adjusting the rotation of the lead screw 43.
[0033] Before operation, the screw 43 is rotated by the control handle 44. The screw 43 moves the cleaning plate 5 away from the filter box 3 via the moving plate 41, so that the filter box 3 filters the silica slurry. After the filter box 3 finishes filtering, the screw 43 is rotated in the opposite direction by the control handle 44. The screw 43 moves the cleaning plate 5 closer to the filter box 3 via the moving plate 41, so that the cleaning brush 51 contacts the filter box 3. The motor 24 is started to rotate the filter box 3. With the help of the cleaning brush 51, the filter holes of the filter box 3 are cleaned and the blockages in the filter holes are scraped off, so as to reduce the impact of blockages on the subsequent filtration effect. The scraped blockages are discharged through the bottom discharge port 8.
[0034] As a possible implementation of this solution, preferably, the top of the limiting plate 63 is provided with a sealing end 64, and the bottom of the filter box 3 is provided with a sealing groove 33. The sealing end 64 and the sealing groove 33 are adapted to each other. The sealing end 64 and the sealing groove 33 are adapted to each other and are slidably connected. With the cooperation of the sealing end 64 and the sealing groove 33, liquid leakage can be avoided.
[0035] As a possible implementation of this solution, preferably, the housing 1 is provided with connecting ears 13 around its perimeter, and the sealing cover 2 is provided with connecting ends 22 around its perimeter corresponding to the connecting ears 13. The connecting ears 13 and the connecting ends 22 are two sets of matching L-shaped parts. The connecting ears 13 and the connecting ends 22 are fixedly connected by bolts 23. Through the cooperation of the L-shaped connecting ears 13 and the connecting ends 22, the sealing cover 2 and the housing 1 are quickly locked together under the connection action of the bolts 23, which facilitates later opening and maintenance.
