Technical Field
[0001] This utility model belongs to the field of brine salt production and impurity removal technology, specifically referring to a brine salt production liquid recovery and impurity removal device. Background Technology
[0002] In the brine salt production process, the purification and removal of impurities from the brine is a crucial pretreatment step, and its effectiveness directly affects the quality of the final salt product. Brine usually contains impurity ions such as calcium and magnesium. Traditional processes often introduce carbon dioxide gas to generate precipitates such as calcium carbonate and magnesium hydroxide to remove impurities.
[0003] In existing technologies, the brine after the reaction in common impurity removal reaction devices usually flows out through the discharge pipe at the bottom, while the sediment is intercepted and filtered through the built-in filter screen. After long-term use, the filter screen will be clogged by sediment, affecting the filtration efficiency and discharge speed. The filter screen is usually fixed inside the device, making cleaning or replacement extremely inconvenient. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a brine salt production solution recovery impurity removal device, which effectively solves the problem of inconvenience in cleaning the filter components.
[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A brine salt production liquid recovery and impurity removal device includes a housing with a feed pipe at the top and an air inlet pipe on one side. The housing is inverted conical in shape, and a discharge pipe is threadedly connected to its bottom. A stirring device is provided inside the housing. A driving structure for driving the stirring device is provided at the top of the housing. A filter screen plate is fixedly installed inside the discharge pipe, and a discharge port is opened at its bottom.

[0007] Preferably, the drive structure includes a motor fixedly mounted on the top of the housing, a first gear fixed on the output shaft of the motor, and a second gear meshing with the first gear sleeved on the top extension end of the rotating shaft.
[0008] Preferably, an L-shaped support plate is installed on the top of the housing, and a cylinder is vertically installed on the top of the support plate. The movable end of the cylinder is fixedly connected to the top of the support column to drive the cover plate to rise and fall.
[0009] Preferably, the top of the support column extends through the center of the rotating shaft to above the rotating shaft, and the support column and the rotating shaft slide and rotate relative to each other.
[0010] Preferably, the edge of the scraper is in close contact with the inverted conical inner wall of the housing.
[0011] Preferably, the cover plate is a conical structure adapted to the inner diameter of the discharge pipe, and the side of the cavity above the filter plate inside the discharge pipe is inclined and smoothly transitions to the outlet of the shell.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.
[0021] like Figure 1-4 As shown, the present invention proposes a brine salt production liquid recovery and impurity removal device, which includes a housing 1 with a feed pipe 2 at the top and an air inlet pipe 3 on one side. The housing 1 is inverted conical in shape, and a discharge pipe 4 is threadedly connected to its bottom. A stirring device 13 is provided inside the housing 1, and a driving structure 14 for driving the stirring device 13 can be provided at the top. A filter screen plate 5 is fixedly installed inside the discharge pipe 4, and a discharge port 6 is opened at its bottom. A cover plate 7 is sealed above the filter screen plate 5, and a support column 8 is fixedly connected to the top of the cover plate 7. The top of the support column 8 extends upward.
[0022] like Figure 2 , 3 As shown, the stirring device 13 includes a rotating shaft 9, which passes through the top of the housing 1 and is rotatably connected thereto, and extends into the housing 1. A connecting rod 10 is fixed outside the rotating shaft 9, and a spiral stirring rod 11 is fixed on the connecting rod 10. A scraper 12 that is close to the inner wall of the housing 1 is fixed on the blade of the spiral stirring rod 11. The edge of the scraper 12 is in close contact with the inverted conical inner wall of the housing 1.
[0023] like Figure 1 , 4 As shown, the drive structure 14 includes a motor 15 fixedly installed on the top of the housing 1. A gear 16 is fixed on the output shaft of the motor 15. A gear 17 that meshes with the gear 16 is sleeved on the top extension end of the rotating shaft 9. The motor 15 drives the gear 16 to rotate, which in turn drives the gear 17 and the rotating shaft 9 to rotate, thereby driving the spiral stirring rod 11 to rotate, so that carbon dioxide and brine react fully.
[0024] like Figure 3 , 4 As shown, an L-shaped support plate 18 is installed on the top of the housing 1. A cylinder 19 is vertically installed on the top of the support plate 18. The movable end of the cylinder 19 is fixedly connected to the top of the support column 8 to drive the cover plate 7 to rise and fall. The top of the support column 8 extends through the center of the rotating shaft 9 to the top of the rotating shaft 9. The support column 8 and the rotating shaft 9 slide and rotate relative to each other. The support column 8 does not affect the normal rotation of the rotating shaft 9.
[0025] like Figure 3 As shown, the cover plate 7 is a conical structure that matches the inner diameter of the discharge pipe 4. The side of the cavity above the filter plate 5 inside the discharge pipe 4 is inclined and smoothly transitions to the outlet of the shell 1, which facilitates the falling of sediment. The cavity above the filter plate 5 inside the discharge pipe 4 is an inverted conical structure and gradually narrows towards the discharge port 6, which facilitates the discharge of brine.
[0026] In practical use, brine is injected into the shell 1 through the feed pipe 2 at the top of the shell 1, and carbon dioxide gas is introduced through the air inlet pipe 3 on one side of the shell 1. The motor 15 is started, and the output shaft of the motor 15 drives the gear 16 to rotate. The gear 16 drives the gear 17 to rotate, which in turn causes the rotating shaft 9 to start rotating. The rotating shaft 9 drives the spiral stirring rod 11 and the scraper 12 on it to rotate together through the connecting rod 10. The spiral stirring rod 11 strongly stirs the brine in the shell 1, so that the introduced carbon dioxide gas is fully mixed and reacted with the brine to generate precipitates such as calcium carbonate and magnesium hydroxide. During the rotation, the scraper 12 moves closely against the inverted conical inner wall of the shell 1, scraping off any precipitates that may be attached to the wall, allowing them to participate in the circulation and preventing scaling.
[0027] After the reaction is completed, the control cylinder 19 retracts, and the movable end of the cylinder 19 pulls the support column 8 and the sealing cover plate 7 fixed thereto upward, so that the cover plate 7 is separated from the filter screen plate 5, and the discharge port 6 at the bottom of the discharge pipe 4 is opened. Under the action of gravity, the brine passes through the filter screen plate 5 in the discharge pipe 4 for filtration. After purification, the brine is discharged from the discharge port 6, while the sediment is intercepted on the filter screen plate 5.
[0028] When it is necessary to clean the sediment residue accumulated on the filter screen, manually unscrew the threaded discharge pipe 4 from the bottom of the housing 1 to easily rinse or treat the entire discharge pipe 4 and filter screen 5. After cleaning, screw the discharge pipe 4 back into the housing 1, extend the control cylinder 19, and push the sealing cover 7 down until it re-seals with the filter screen 5, and you can prepare for the next impurity removal operation.
[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
