Technical Field
[0001] This utility model relates to the field of lithium carbonate processing technology, specifically to a sedimentation extraction device for lithium carbonate processing. Background Technology
[0002] Lithium carbonate is an inorganic substance, belonging to the lithium salt of carbonates. It is slightly soluble in water, soluble in acid, and non-flammable. It is widely used in medical, industrial, and aerospace fields. However, in the process of lithium carbonate processing, sedimentation extraction devices are required for sedimentation extraction.
[0003] For example, Chinese utility model patent CN218642487U discloses a lithium carbonate sedimentation extraction device, including a base, a sedimentation cylinder, and a separation cylinder. The sedimentation cylinder is installed on the base, and the separation cylinder is located inside the sedimentation cylinder. A drive motor is installed at one end of the sedimentation cylinder, and the output end of the drive motor passes through the sedimentation cylinder through a drive shaft and is connected to one end of the separation cylinder. Taking advantage of the characteristic that lithium carbonate is poorly soluble in hot water, hot water is used to wash the lithium carbonate in the lithium carbonate solution. Then, a carbonation precipitant is used to react with the lithium carbonate, causing the lithium carbonate to settle rapidly. During the rotation of the separation cylinder driven by the drive motor, the hot water inside is discharged through the filter holes, while the lithium carbonate is isolated by the filter screen inside the separation cylinder to complete the extraction work. This avoids the need to transfer the lithium carbonate to a sedimentation separation device for extraction after sedimentation, which is too cumbersome and increases the workload.
[0004] However, existing sedimentation extraction devices for lithium carbonate processing still have some problems during use, such as difficulty in heating and stirring, difficulty in accelerating the sedimentation of lithium carbonate, difficulty in filtering, separating and washing the sedimented lithium carbonate, and limited precision of extracted lithium carbonate. Therefore, we propose a sedimentation extraction device for lithium carbonate processing to solve the problems mentioned above. Utility Model Content

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] Please see Figure 1-6 This utility model provides a technical solution: a sedimentation extraction device for lithium carbonate processing, comprising a cylinder 1, a cylinder cover 2, a fixing plate 3, a first solenoid valve 4, a first heat-conducting plate 5, a heating tube 6, a stirring rod 7, a motor 8, a scraper 9, a controller 10, a filter plate 11, a receiving plate 12, a surrounding plate 13, a sealing gasket 14, a limiting strip 15, a nozzle 16, a second solenoid valve 17, a water inlet pipe 18, a third solenoid valve 19, a drain pipe 20, a second heat-conducting plate 21, a connecting sleeve 22, a fourth solenoid valve 23, a water pipe 24, and a purification system. Plate 25 and fifth solenoid valve 26, cylinder cover 2 rotatably connected to the inner side of the upper right end of cylinder 1 and fixed plate 3 fixedly connected inside cylinder 1, first solenoid valve 4 fixedly installed inside fixed plate 3, and accelerated sedimentation structure and extraction washing structure respectively provided on the upper and lower sides of fixed plate 3, second heat conduction plate 21 and connecting sleeve 22 fixedly connected to the upper left of cylinder 1, and fourth solenoid valve 23 fixedly installed on the inner side of the upper left end and the inner side of the lower left end of second heat conduction plate 21, and water pipe 24 is externally threaded to the fourth solenoid valve 23.
[0031] To address the problems in existing technologies, such as the inconvenience of heating and stirring, the difficulty in accelerating the sedimentation of lithium carbonate, the difficulty in filtering and washing the sedimented lithium carbonate, and the limited precision of extracted lithium carbonate, this embodiment employs the following technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 5 The operator can first rotate the cylinder cover 2, which is rotatably connected to the upper right end of the cylinder 1, to disconnect the cover from the cylinder 1. Then, the pretreated brine and soda ash reactants can be added to the inner upper part of the cylinder 1 to allow for precipitation. After the addition is complete, the cylinder cover 2 can be rotated again to restore its original position and block the cylinder 1. The operator can then control the heating tube 6 embedded in the first heat-conducting plate 5 via the controller 10 installed on the inner rear upper part of the cylinder 1. Since the inner lower part of the cylinder 1 is fixedly connected to a fixing plate 3, and the inner middle part of the first solenoid valve 4 is fixedly installed, a connection is provided above the outer part of the first solenoid valve 4 to the cylinder 1. The first heat-conducting plate 5 is fixedly connected to the fixed plate 3. Therefore, through the operation of the heating pipe 6, the brine and soda ash in the cylinder 1 and the fixed plate 3 are heated by the heat conduction of the first heat-conducting plate 5. The motor 8 connected to the coupling on the stirring rod 7 can be controlled by the controller 10 to operate, so that the motor 8 drives the stirring rod 7 to rotate under the locking limit of the cylinder 1 to stir the brine and soda ash. The stirring rod 7 also drives the scraper 9 symmetrically fixed on its outside to rotate, scraping the cylinder 1, cylinder cover 2, first solenoid valve 4 and first heat-conducting plate 5 that are attached to the outside of the scraper 9, thereby facilitating heating and stirring, and achieving the purpose of accelerating the sedimentation of lithium carbonate.
[0032] like Figure 1 , Figure 3 and Figure 6 After the lithium carbonate has settled, the controller 10 can control the first solenoid valve 4 fixedly installed inside the fixed plate 3 and the third solenoid valve 19 fixedly installed on the inner side of the lower right end of the cylinder 1 to operate, so that the first heat-conducting plate 5 is connected to the fixed plate 3, so that the solution in the cylinder 1 and the fixed plate 3 can fall. Since a filter plate 11 nested and attached to the cylinder 1 is provided below the fixed plate 3, and a receiving plate 12 fixed to the cylinder 1 is attached to the lower outer side of the filter plate 11, and the outer side of the filter plate 11... A retaining plate 13 is fixedly connected to the rear side and nested and fitted with the cylinder 1. A sealing gasket 14 that fits tightly with the cylinder 1 is pasted and fixed to the outer side of the inner end of the retaining plate 13. A limiting strip 15 that is connected to the cylinder 1 for damping rotation is also attached to the rear side of the upper end of the retaining plate 13. Therefore, it is convenient for the filter plate 11 to filter and separate lithium carbonate in the falling solution under the support of the receiving plate 12 and the sealing of the retaining plate 13 and the sealing gasket 14. The separated solution is discharged through the drain pipe 20 connected to the third solenoid valve 19.
[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4Then, the controller 10 can control the second solenoid valve 17 fixedly installed on the inner side of the front end of the cylinder 1 and the third solenoid valve 19 fixedly installed on the inner side of the lower left end of the cylinder 1 to perform the operation. Since the second solenoid valve 17 is located above the front of the fixed plate 3, and the fixed plate 3 is connected to the centrally symmetrical nozzle 16 by the internal thread, it is convenient to allow the hot water in the water inlet pipe 18 to enter the inner side of the cylinder 1, the fixed plate 3 and the first heat conduction plate 5, so that it is sprayed onto the lithium carbonate filtered and separated on the filter plate 11 through the nozzle 16, washing the filtered and separated lithium carbonate, and allowing the washing water to be discharged through the drain pipe 20 set on the left, thereby facilitating the extraction of high-quality lithium carbonate. After washing, the limiting strip 15 can be rotated to disconnect its attachment limit to the surrounding plate 13, and the surrounding plate 13 can be pulled outward, so that the surrounding plate 13 drives the filter plate 11 to move backward until the filter plate 11 is separated from the cylinder 1, so that the lithium carbonate on the filter plate 11 can be collected.
[0034] like Figure 1 , Figure 2 and Figure 3 During the lithium carbonate sedimentation and separation process, the fifth solenoid valve 26, which is fixedly installed on the inner side of the upper left end of the cylinder 1, can be controlled by the controller 10 to operate, so that the cylinder 1 and the second heat-conducting plate 21 fixedly connected to the upper left end are connected. Since the second heat-conducting plate 21 is provided with a connecting sleeve 22 fixedly connected to the cylinder 1, the fourth solenoid valve 23 with an outer threaded connection to the water pipe 24 is fixed on the inner side of the left outer end of the connecting sleeve 22, and the purification plate 25 located on the second heat-conducting plate 21 is nested and attached to the inner side of the upper end of the connecting sleeve 22, it is convenient to conduct heat through the second heat-conducting plate 21 to heat up the water in the second heat-conducting plate 21 and the connecting sleeve 22, so that the water can be drained through the fourth solenoid valve 23 and the water pipe 24 to achieve the purpose of heat recovery, and to facilitate purification treatment through the purification plate 25 protruding inside the connecting sleeve 22. All the electrical components mentioned above are existing technologies and will not be described in detail here.
