Description

Technical Field

[0001] This utility model relates to the field of manganese processing and extraction technology, and in particular to a filtration device for sulfuric acid leaching manganese electrolyte. Background Technology

[0002] Sulfuric acid leaching of manganese refers to leaching manganese ore with sulfuric acid to obtain a manganese-containing solution, followed by electrolytic extraction of metallic manganese or other manganese products. During the sulfuric acid leaching process, insoluble residues from the ore exist in the solution as suspended solids or colloids. If these impurities are not removed, they may deposit on the electrode surface during electrolysis, clogging electrode pores, reducing the effective reaction area of ​​the electrode, and causing short circuits between electrodes due to particle accumulation, affecting electrolytic stability. Impurities may also be encapsulated in the metallic manganese deposited at the cathode, reducing product purity.

[0003] In existing technologies, the filtration of sulfuric acid-leached manganese electrolyte typically employs a box filter press. After filtration, soluble manganese, ammonium sulfate, and other extracts remain on the filter bag, which cannot be recycled, resulting in resource waste. Furthermore, with repeated filtrations, impurities accumulate and clog the filter pores, reducing filtration efficiency. Therefore, a filtration device is needed that can improve filtration efficiency and collect impurities. Utility Model Content

[0004] This utility model addresses the technical problem that during the filtration of sulfuric acid manganese leaching electrolyte, extracts are adsorbed onto the filter layer and cannot be recovered, while impurities clog the filter pores. It provides a filtration device for sulfuric acid manganese leaching electrolyte, including a filter tank. The top and bottom of the filter tank are respectively provided with a feeding port and a discharging port, both of which are connected to the interior of the filter tank.

[0005] A vertical partition is provided on the right side inside the filter tank. A first bearing is embedded in the vertical partition.

[0008] Below the slag receiving and filtering device is a liquid storage tank. A circulating water outlet device is fixedly connected to the top of the filter tank. A circulating pump and a connecting pipe connected to the circulating pump are provided on one side of the vertical partition. One end of the connecting pipe is connected to the liquid storage tank, and the other end is connected to the circulating water outlet device.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-5As shown, this utility model discloses a filtration device for sulfuric acid leaching manganese electrolyte, comprising a filter tank 1. The filter tank 1 has a feed inlet 2 and a discharge inlet 3 at its top and bottom, respectively, both connected to the interior of the filter tank 1. The feed inlet 2 is rectangular with a large diameter, allowing the sulfuric acid leaching manganese electrolyte to be transported and added via a pipeline. The discharge inlet 3 is a cylindrical pipe, allowing external pipeline access to the next process. A vertical partition 11 is located on the right side of the interior of the filter tank 1, dividing the left side of the filter tank 1 into a filtration zone and the right side into a backwashing pipeline zone. A first bearing 12 is embedded in the vertical partition 11, and a second bearing 13 is embedded in the filter tank 1 at the corresponding position of the first bearing 12. A flip filter device 5 is connected between the first bearing 12 and the second bearing 13. The flip filter device 5 can rotate inside the filter tank 1. The flip filter device 5 includes a rotating shaft 51 and three filter plates 52 connected to the rotating shaft 51. The three filter plates 52 are all fixed to the rotating shaft 51 at a 120° angle. When the flip filter device 5 rotates forward, the three filter plates 52 can provide the continuity of the filter plates, and can perform the first-stage filtration under the continuous feeding of the feed port 2, so that the filtration effect is more complete. The lower part of the filter tank 1 is equipped with a slag-receiving filter device 6. A rectangular through-hole 14 is provided on one side of the filter tank 1 below. At least two fixing strips 15 are correspondingly provided on the inner wall of the filter tank 1 to ensure that the slag-receiving filter device 6 can pass through the rectangular through-hole 14 and be detachably connected to the filter tank 1 along the fixing strips 15. A rectangular sealing rubber ring 16 is provided around the inner ring of the rectangular through-hole 14. The sealing rubber ring 16 improves the airtightness after the slag-receiving filter device 6 is inserted into the filter tank 1, preventing the sulfuric acid manganese leaching electrolyte from overflowing from the gap between the slag-receiving filter device 6 and the filter tank 1 during the filtration process, thus avoiding resource waste and environmental pollution. The slag-receiving filter device 6 can perform secondary filtration of the sulfuric acid manganese leaching electrolyte, thoroughly removing excess impurities and improving the purity and quality of the extract. Below the slag receiving and filtering device 6 is a liquid storage tank 8. A circulating water outlet device 72 is fixedly connected to the top of the filter tank 1. A circulating pump 7 and a connecting pipe 71 connected to the circulating pump 7 are located on one side of the vertical partition 11. One end of the connecting pipe 71 is connected to the liquid storage tank 8, and the other end is connected to the circulating water outlet device 72. The circulating water outlet device 72 is a rectangular ring, fitted onto the feeding port 2, and has multiple spray nozzles 73 at its bottom. The circulating water outlet device 72 and the feeding port 2 are on the same axis to maximize the filtration and backwashing effect. The number of spray nozzles 73 can be adjusted according to the specific size of the circulating water outlet device 72, ensuring that the circulating water outlet device 72 can stably spray electrolyte at a certain flow rate to wash the impurities adsorbed on the filter plate 52 onto the slag receiving and filtering device 6.A regulating valve 31 is fitted onto the discharge port 3. The regulating valve 31 can adjust and control the filtered electrolyte to ensure that the storage tank 8 contains a sufficient amount of electrolyte, enabling the circulating pump 7 to pump a sufficient amount of electrolyte into the circulating water outlet device 72. A support plate 41 is fixedly connected to one side of the filter tank 1, and a low-speed motor 4 is mounted on the support plate 41. The output end of the low-speed motor 4 is fixedly connected to one end of the rotating shaft 51 to ensure that the low-speed motor 4 can drive the tilting filter device 5 to rotate.

[0031] In this embodiment, the slag receiving and filtering device 6 includes a slag receiving and filtering plate 62 and four fixed anti-collision strips 63. A push-pull plate 61 is connected to one side of the slag receiving and filtering device 6, and the size of the push-pull plate 61 matches that of the rectangular through hole 14. The four fixed anti-collision strips 63 are respectively fixedly connected to the four edges of the slag receiving and filtering plate 62 and are parallel to the fixed strips 15. When the slag receiving and filtering device 6 is disassembled, the fixed anti-collision strips 63 can prevent the slag receiving and filtering plate 62 from being deformed due to collision when the slag receiving and filtering device 6 is moved, thereby affecting the filtering effect. A push-pull handle 611 is connected to the outside of the push-pull plate 61. At least two push-pull handles 611 are provided to facilitate the operation of the operator in a more labor-saving manner when disassembling, cleaning and reinstalling. Both the filter plate 52 and the slag receiving and filtering plate 62 are made of micron-sized polypropylene filter material. Micron-sized polypropylene filter media can intercept suspended particles (such as impurities and small amounts of crystals) in sulfuric acid manganese leaching electrolyte, while allowing soluble manganese and ammonium sulfate to pass through freely, thus improving the filtration effect of sulfuric acid manganese leaching electrolyte.

[0032] During operation, the sulfuric acid manganese leaching electrolyte to be filtered is transported to the top of the feeding port 2 through an external pipeline. The low-speed motor 4 is started to rotate forward, driving the rotating filter device 5 to rotate. Under the action of gravity, the sulfuric acid manganese leaching electrolyte passes through the filter plate 52 for the first filtration. Filter residue and impurities adhere to the filter plate 52. Subsequently, the sulfuric acid manganese leaching electrolyte after the first filtration passes through the slag receiving filter device 6 for the second filtration. After filtration on both sides, the sulfuric acid manganese leaching electrolyte enters the storage tank 8. After filtration, the low-speed motor 4 is controlled to reverse and the circulation pump 7 is turned on. The filtered sulfuric acid manganese leaching electrolyte is pumped into the circulating water outlet device 72 through the connecting pipeline 71, so that the filtered sulfuric acid manganese leaching electrolyte is evenly sprayed out from the circulating water outlet device 72 and passes through the other side of the filter plate 52. The impurities attached to the filter plate 52 are backwashed and fall into the slag receiving filter device 6. After rinsing, the regulating valve 31 is opened so that the filtered sulfuric acid manganese leaching electrolyte flows out from the discharge port 3 for the next process operation. After multiple uses of filtration, the operator can pull out the slag receiving filter device 6 by pushing and pulling handle 611, and wash and clean the impurity particles deposited on the slag receiving filter device 6 to avoid the reduction and consumption of filtration effect.

[0033] This invention utilizes a dual-filtration system—a tilting filter and a slag-collecting filter—to perform double filtration of the sulfuric acid-leached manganese electrolyte, improving filtration efficiency and preventing soluble manganese and ammonium sulfate extracts from adhering to the filter layer, thus avoiding incomplete recovery. The tilting filter and the circulating water outlet can work together. Normal filtration occurs when the tilting filter rotates forward; when it rotates backward, the filtered solution is sprayed out through the circulating water outlet via a circulating pump, flushing impurities adhering to the tilting filter into the slag-collecting filter. After filtration, the slag-collecting filter can be removed from the filter tank to clean its surface, preventing clogging of the filter pores and improving filtration efficiency. This solves the problems of extract adsorption on the filter layer and difficulty in recovery, as well as impurities clogging the filter pores, further improving both filtration efficiency and filtration quality.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
