Description

Technical Field

[0001] This invention relates to the field of chemical production technology, specifically a filtration device for producing high-purity manganese sulfate. Background Technology

[0002] Currently, manganese sulfate, as a basic manganese salt, is widely used in industries such as pharmaceuticals, food, pesticides, papermaking, and catalysts. Manganese sulfate is a trace element required by crops for synthesizing fatty acids and can be applied to the soil as a fertilizer. Adding manganese sulfate to animal feed has a fattening effect. Manganese sulfate is also a raw material and analytical reagent for preparing other manganese salts. It is also used in the industrial production of electrolytic manganese, dyes, papermaking, and ceramics. Manganese sulfate solutions contain heavy metal impurities such as calcium, magnesium, and nickel, as well as water-insoluble residues. Therefore, when producing or crystallizing manganese sulfate solutions, it is necessary to filter the impurities in the solution to improve product quality. To address this, we have designed a filtration device for producing high-purity manganese sulfate, which has good filtration effects, is easy to clean, and prevents filter mesh clogging.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-6A filtration device for producing high-purity manganese sulfate includes a first filtration device and a second filtration device. The first filtration device is used for coarse filtration of raw materials during the production process, and the second filtration device is used for fine filtration during the manganese sulfate production process. The first filtration device includes a first filter tank 1, a tank cover 2, and a filtration structure. A limiting ring 3 is fixedly connected to the inner side of the inlet at the upper end of the first filter tank 1. The limiting ring 3 is used to relatively limit and fix the filtration structure. The filtration structure is set inside the limiting ring 3 and is used to filter impurities during the manganese sulfate production process. The tank cover 2 is hinged to one side of the upper end of the first filter tank 1. A latch 4 is provided between the other side of the tank cover 2 and the first filter tank 1. The latch 4 is used to relatively fix the tank cover 2 to the first filtration device. The can lid 2 is connected to the middle of the can by a feed pipe 5. In use, the feed pipe 5 is connected to the feed device to put the raw materials into the first filter tank 1 for preliminary filtration. The lower side wall of the first filter tank 1 is fixedly connected to the output pipe 6. The other end of the output pipe 6 is connected to the guide device. The guide device is used to extract the raw material liquid that has been preliminarily filtered in the first filter tank 1 and transport it to the second filter device. The guide device is fixedly connected to one side of the second filter device and is connected to the second filter device through the guide pipe 16. In this invention, when it is necessary to clean the filter structure, simply open the latch 4, flip up the can lid 2, and take out the filter structure on the limiting ring 3 to complete the cleaning operation.

[0022] In one embodiment, the filter structure includes a fixing ring 7, a filter screen 8, and a handle 9. The fixing ring 7 is in contact with the upper end of the limiting ring 3. The filter screen 8 is fixedly connected to the inner ring edge of the fixing ring 7. The filter screen 8 passes through the limiting ring 3 and is placed inside the first filter tank 1. The two ends of the handle 9 are rotatably connected to the inner ring side wall of the fixing ring 7. In use, the raw material liquid is directly filtered through the filter screen 8. The handle 9 is used to facilitate the handling of the filter structure.

[0023] In one embodiment, a first sealing ring 10 is fitted onto the limiting ring 3 opposite to the fixing ring 7, and a second sealing ring 11 is fixedly connected onto the can lid 2 opposite to the fixing ring 7. When the can lid 2 is closed on the first filter can 1, the first sealing ring 10 is used to improve the sealing between the fixing ring 7 and the limiting ring 3, and the second sealing ring 11 is used to improve the connection sealing between the can lid 2 and the fixing ring 7, preventing the raw material liquid from flowing out of the gap between the first filter can 1 and the can lid 2 to the outside of the can lid 2, or preventing impurities in the raw material liquid from entering the first filter can 1 through the gap between the fixing ring 7 and the limiting ring 3, resulting in poor filtration effect.

[0024] In one embodiment, the material guiding device includes a material guiding cylinder 12, a piston block 13, a piston rod 14, and a one-way valve. The material guiding cylinder 12 is fixedly connected to one side of the second filter device. An output pipe 6 is fixedly connected to the lower side wall of the material guiding cylinder 12. A piston block 13 is connected to the piston inside the material guiding cylinder 12. A piston rod 14 is fixedly connected to the upper end of the piston block 13. The upper end of the piston rod 14 passes through the material guiding cylinder 12 and is connected to a transmission mechanism. The transmission mechanism is associated with the second filter device. A sealing structure is provided between the piston rod 14 and the material guiding cylinder 12. Several through holes 15 extend through the piston block 13 vertically. One-way valves are fixedly installed in the through holes 15 and at the connection between the output pipe 6 and the material guiding cylinder 12. A material guiding pipe 16 is fixedly connected to the upper side wall of the material guiding cylinder 12. The mechanism includes a first synchronous pulley 24, a second synchronous pulley 25, a first steering pulley 26, a second steering pulley 27, a rotating disk 28, a linkage rod 29, and a U-shaped frame 30. The upper end of the piston rod 14 is rotatably connected to the U-shaped frame 30, and the linkage rod 29 is fixedly connected to the U-shaped frame 30. One end of the linkage rod 29 is rotatably connected to the end of the rotating disk 28 near its outer edge. One end of the central axis of the rotating disk 28 is fixedly connected to the second steering pulley 27. The central axis between the second steering pulley 27 and the rotating disk 28 is rotatably connected to a support plate 31. The support plate 31 is fixedly connected to one side of the upper edge of the second filter tank 17. The second steering pulley 27 meshes with the first steering pulley 26. A first steering gear is rotatably connected to one side of the upper edge of the second filter tank 17. A second synchronous pulley 25 is fixedly connected to the central shaft of the gear. The second synchronous pulley 25 is connected to the first synchronous pulley 24 via a synchronous belt. The first synchronous pulley 24 is fixedly connected to the rotating shaft 21 below the connecting frame 19. In use, the drive motor 20 drives the rotating shaft 21 to rotate, which in turn drives the first synchronous pulley 24 to rotate. The first synchronous pulley 24 drives the second synchronous pulley 25 to rotate via the synchronous belt. The second synchronous pulley 25 drives the first steering pulley 26 to rotate, which in turn drives the second steering pulley 27 to rotate. The second steering pulley 27 drives the rotating disk 28 to rotate. The other side of the rotating disk 28 drives one end of the linkage rod 29 to perform a circular motion, causing the other end of the linkage rod 29 to drive the piston rod 14 to perform a reciprocating up-and-down motion. The piston rod 14 moves upward. When moving, the piston block 13 moves upward, increasing the volume below the piston block 13 and decreasing the air pressure. This causes the raw material liquid in the first filter tank 1 to be drawn into the guide cylinder 12. The material liquid in the volume above the piston block 13 cannot enter below the piston block 13 due to the action of the one-way valve. However, as the volume decreases, the raw material liquid is squeezed into the second filter tank 17 through the guide pipe 16. When the piston rod 14 moves the piston block 13 downward, the volume below the piston block 13 decreases, causing the raw material liquid to be squeezed and enter the volume chamber above the piston block 13 through the through hole 15. Through the one-way valve, the raw material liquid cannot return to the first filter tank 1. This process is repeated to transfer the raw material liquid from the first filter tank 1 to the second filter tank 17.

[0025] In one embodiment, the second filtration device includes a second filter tank 17, filter plates 18, a drive motor 20, a guiding structure, and a discharge pipe 23. A connecting frame 19 is fixedly connected to the upper middle part of the second filter tank 17, and a drive motor 20 is fixedly connected to the upper end of the connecting frame 19. A rotating shaft 21 is fixedly connected to the rotating shaft of the drive motor 20, and a guiding structure is fixedly connected to the rotating shaft 21. The guiding structures are respectively connected to the filter plates 18. Two sets of opposing filter plates 18 are fixedly connected inside the second filter tank 17. A bent guide tube 22 is fixedly connected to the second filter tank 17 on the side of the filter plates 18 that are separated. The filter plates 18 are all located between the two guide tube openings of the bent guide tube 22. A discharge pipe 23 is fixedly connected to the second filter tank 17 between the two sets of filter plates 18. In specific operation, the raw material liquid in the first filter tank 1 is continuously transported to the second filter tank 17 through the guiding device. Then, the raw material liquid is filtered again through the two sets of filter plates 18 in the second filter tank 17. The filtered raw material liquid is discharged through the discharge pipe 23.

[0026] In the above embodiment, the space between the two sets of filter plates 18 can be filled with filter materials such as filter cotton, activated carbon, and filter non-woven fabric to improve the filtration effect of the raw material liquid.

[0027] In one embodiment, the dredging device includes a rotating shaft 32, a roller sleeve 33, a brush 34, a transmission gear 35, a toothed ring 36, and a scraper 37. The rotating shaft 21 passes through and is rotatably connected to the filter plate 18. Several rotating shafts 32 are respectively arranged on opposite sides of the two sets of filter plates 18. One end of each rotating shaft 32 is fixedly connected to the rotating shaft 21. A scraper 37 is arranged between adjacent sets of rotating shafts 32, with one end of the scraper 37 also fixedly connected to the rotating shaft 21. One side of the scraper 37 is in contact with the filter plate 18. A roller sleeve 33 is rotatably connected to each rotating shaft 32. A brush 34 is arranged on the outer periphery of the roller sleeve 33, and the brush 34 is in contact with the filter plate 18. A transmission gear 35 is fixedly connected to the end of each roller sleeve 33. The transmission gear 35 meshes with the corresponding toothed ring 36. The toothed rings 36 are fixedly connected to the inner wall of the second filter tank 17. During the filtration process, the drive motor 20 drives the rotating shaft 21 to rotate, which in turn drives the rotating shaft 32 and the scraper 37 to rotate. As the scraper 37 rotates on the surface of the filter plate 18, it can scrape off the impurities on the surface of the filter plate 18 to prevent the impurities from clogging the filter holes. At the same time, as the rotating shaft 32 rotates, it drives the roller sleeve 33 to rotate as well, causing the transmission gear 35 at the end of the roller sleeve 33 to rotate along the inner wall of the second filter tank 17. Simultaneously, the toothed rings 36 cause the transmission gear 35 to rotate relative to the roller sleeve 33. The transmission gear 35 drives the roller sleeve 33 to rotate, and the brush 34 on the roller sleeve 33 rotates and brushes the filter plate 18, which can effectively remove the impurities on the surface of the filter plate 18 and further prevent the filter holes from being clogged.

[0028] In one embodiment, two sets of symmetrical handles 38 are fixedly connected to the upper end of the can lid 2 for easy lifting and turning of the can lid 2. A transparent observation window 39 is provided on the can lid 2 between the handles 38. The transparent observation window 39 is used to easily and intuitively understand the impurities in the filter structure and to easily determine whether cleaning is required. A liquid level observation window 40 is provided on the wall of the first filter tank 1. The liquid level observation window 40 is used to intuitively understand the liquid level of the filtered raw liquid in the first filter tank 1.
