Description

Technical Field

[0001] This utility model belongs to the field of sedimentation tank technology, specifically a sedimentation tank device used in lithium carbonate production. Background Technology

[0002] In activated sludge treatment equipment and coagulation sedimentation treatment equipment, the common method for separating sludge mixture (coagulated treatment liquid) into treated water and sludge is sedimentation separation using a solid-liquid separation tank (sedimentation tank). In this sedimentation separation, in order to efficiently remove turbidity and fine suspended solids (SS) from the sludge mixture and obtain good treated water, a sludge zone (sludge blanket) is formed in the sedimentation tank. The sludge mixture flows into the lower part of the sludge zone through a central well (supply well), thereby filtering and separating the turbidity and fine SS in the sludge mixture using a sludge blanket filtration method.

[0003] Existing sedimentation tanks have a fixed depth, and the processed sediment is not easy to remove. In particular, there are often foreign objects on the tank walls after sedimentation, making the cleaning work after processing extremely cumbersome. This not only increases the workload but also prolongs the waiting time for subsequent processing, thereby reducing the efficiency of use and production. Therefore, it is necessary to develop a sedimentation tank device for lithium carbonate production to solve the shortcomings of the existing technology. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a precipitation tank device for lithium carbonate production, which has advantages such as ease of cleaning.

[0009] Preferably, a plurality of evenly distributed positioning support columns are fixedly installed at the bottom of the sedimentation chamber, and the upper end of the positioning support column abuts against the top of the concave inner cavity at the bottom of the sedimentation plate. When the bottom of the sedimentation plate abuts against the top of the positioning support column, the top of the sedimentation plate is located inside the sealing assembly.

[0010] Preferably, the sealing assembly includes a second air chamber located inside the sedimentation chamber and outside the upper end of the sedimentation plate.

[0025] 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.

[0026] like Figures 1 to 6 As shown, this utility model provides a precipitation tank device for lithium carbonate production, including a precipitation tank 1, a precipitation chamber 2 opened at the top of the precipitation tank 1, a precipitation base 3 movably installed inside the precipitation chamber 2, a sealing component 4 embedded in the inner wall of the precipitation chamber 2, the outer surface of the sealing component 4 sealingly fitting the upper end of the outer surface of the precipitation plate 31, a drive component 5 installed on the side of the precipitation tank 1, and the output end of the drive component 5 connected to the precipitation chamber 2 and the sealing component 4 through a three-way pipe.

[0027] The sedimentation base 3 includes a sedimentation plate 31 movably installed inside the sedimentation chamber 2. A first air chamber 32 is formed on the outer surface of the sedimentation plate 31. An elastic scraper 33 is fixedly sleeved on the outer side of the inner cavity of the first air chamber 32. The outer surface of the elastic scraper 33 is sealed against the inner wall of the sedimentation chamber 2. A first through hole 34 is formed in the middle of the sedimentation plate 31. A first solenoid valve 35 is fixedly installed at the bottom of the sedimentation plate 31. The bottom of the first solenoid valve 35 is connected to one of the output ends of the drive assembly 5 through the sedimentation chamber 2. The two ends of the first through hole 34 are connected to the first air chamber 32. The first through hole 34 is connected to the top of the first solenoid valve 35. Due to the setting of the elastic scraper 33, with the cooperation of the sedimentation chamber 2, it is ensured that the outer side of the sedimentation plate 31 can be sealed with the inner wall of the sedimentation chamber 2, and that the sedimented liquid and sediment can be pushed by the sedimentation plate 31 to the upper end of the inner cavity of the sedimentation chamber 2 for quick removal. Moreover, with the cooperation of the elastic scraper 33, it can effectively reduce the situation that there is a large amount of residue on the inner wall of the sedimentation chamber 2 when manually removing sediment, thereby effectively reducing the cleaning difficulty and improving the efficiency of the continuous sedimentation process.

[0028] The top of the sedimentation plate 31 is a smooth concave surface, and the bottom of the sedimentation plate 31 is also a smooth concave surface. The first through hole 34 is located between the upper and lower concave surfaces, and the first air cavity 32 is located on the outer side between the upper and lower opposing surfaces.

[0029] The sedimentation chamber 2 has two shear balance frames 7 installed at the bottom. The upper end of the shear balance frame 7 is hinged to the concave surface at the bottom of the sedimentation plate 31, and the lower end of the shear balance frame 7 is slidably engaged with the bottom of the sedimentation chamber 2. Due to the installation of the shear balance frame 7, the sedimentation tank 1 and the sedimentation chamber 2 work together to ensure that the drive assembly 5 and the sedimentation base 3 work together to control the sedimentation plate 31 to move up and down, thus maintaining good stability and improving the sealing effect between the outer surface of the elastic scraper 33 and the inner wall of the sedimentation chamber 2.

[0030] The bottom of the sedimentation chamber 2 is fixedly equipped with several evenly distributed positioning support columns 6. The upper end of the positioning support column 6 abuts against the top of the concave inner cavity of the sedimentation plate 31. When the bottom of the sedimentation plate 31 abuts against the top of the positioning support column 6, the top of the sedimentation plate 31 is located inside the sealing component 4. Due to the setting of the positioning support column 6, under the restriction of the sedimentation chamber 2, it can be ensured that the lowest point of the sedimentation plate 31 always remains fixed, thereby ensuring that the outer surface of the sealing film 42 before sedimentation can be tightly attached to the upper end of the outer surface of the sedimentation plate 31 with the cooperation of the driving component 5, etc.

[0031] The sealing assembly 4 includes a second air chamber 41 located inside the sedimentation chamber 2 and outside the upper end of the sedimentation plate 31. A sealing membrane 42 is fixedly sleeved inside the second air chamber 41 on the side closest to the sedimentation chamber 2. The outer surface of the sealing membrane 42 is sealed and fitted to the upper end of the outer surface of the sedimentation plate 31. Due to the setting of the sealing assembly 4, with the cooperation of the driving assembly 5, it can be ensured that the upper end of the inner wall of the sedimentation base 3 can be sealed and fitted to the inner wall of the sedimentation chamber 2, avoiding the situation where the sediment enters the gap between the upper end of the outer surface of the sedimentation plate 31 and the sedimentation chamber 2 during sedimentation, thus increasing the difficulty of cleaning.

[0032] The drive assembly 5 includes a hydraulic pump 51 fixedly installed on the side of the sedimentation tank 1. The output end of the hydraulic pump 51 is connected to two connecting pipes 54 with a second solenoid valve via a three-way valve. A third through hole 53 is provided on the side of the sedimentation tank 1, connecting one of the connecting pipes 54 and the second air chamber 41. A second through hole 52 is also provided on the side of the sedimentation tank 1, connecting the other connecting pipe 54 and the sedimentation chamber 2. Due to the setting of the second solenoid valve, the hydraulic pump 51 can inject hydraulic oil into the second air chamber 41 and the first air chamber 32 respectively through the connecting pipe 54, the sedimentation chamber 2 and the first solenoid valve 35, thereby achieving the effect of controlling the expansion and contraction of the sealing membrane 42 and the elastic support membrane 331.

[0033] The elastic scraper 33 includes an elastic support membrane 331 fixedly sleeved inside the first gas chamber 32. A scraper head 332 is integrally formed on the side of the elastic support membrane 331 near the inner wall of the sedimentation chamber 2. The cross-section of the scraper head 332 is a horizontally placed isosceles triangle. A bonding surface 333 is provided on the outer surface of the scraper head 332 away from the elastic support membrane 331. The bonding surface 333 is sealed and bonded to the inner wall of the sedimentation chamber 2.

[0034] Working principle and usage process of this utility model:

[0035] Open the second solenoid valve in the connecting pipe 54 corresponding to the third through hole 53, and turn on the hydraulic pump 51 to inject hydraulic oil into the second air chamber 41 through the corresponding connecting pipe 54 and the third through hole 53. Then close the second solenoid valve in the connecting pipe 54 to expand the sealing membrane 42, thereby making the sealing membrane 42 tightly adhere to the top of the outer surface of the sedimentation plate 31, ensuring that the top of the sedimentation plate 31 in the sedimentation chamber 2 is a sealed chamber structure with the top open.

[0036] Then, lithium carbonate precipitation can be performed through the above-mentioned sealed cavity structure. After precipitation is completed, the second solenoid valve and the first solenoid valve 35 in another connecting pipe 54 are opened, and hydraulic oil is injected into the bottom of the inner cavity of the precipitation cavity 2 and the bottom of the precipitation plate 31 by the hydraulic pump 51. Under the sealing action of the sealing membrane 42 and the precipitation plate 31, the hydraulic oil continuously entering the bottom of the precipitation plate 31 enters the first air cavity 32 through the first solenoid valve 35 and the first through hole 34, and the elastic scraper 33 expands outward until the outer surface of the contact surface 333 is tightly attached to the inner wall of the precipitation cavity 2. Then, the first solenoid valve 35 is closed, so that the continuously entering hydraulic oil, with the cooperation of the shear balance frame 7, pushes the precipitation plate 31 to move slowly upward with the cooperation of the elastic scraper 33, which is close to the inner wall of the precipitation cavity 2. This ensures that the precipitation and liquid are pushed to the upper end of the inner cavity of the precipitation cavity 2 by the precipitation plate 31, so as to discharge the precipitated liquid and remove the deposits.

[0037] After removing the sediment, lowering the sedimentation plate 31 will expose a small amount of residue on the inner wall of the sedimentation chamber 2, which can then be quickly cleaned by rinsing with clean water.
