[0002] Lithium carbonate is an inorganic compound. It is a colorless monoclinic crystal, slightly soluble in water and dilute acid, insoluble in ethanol and acetone. Lithium carbonate is stable in air and non-deliquescent. It has many uses, including as an oral preparation of lithium salt. In addition, lithium carbonate is also used as a catalyst, additive and intermediate, and is widely used in the chemical industry. Lithium carbonate needs to undergo precipitation operation in production.

[0003] When cleaning sediment, the commonly used sedimentation device needs to clean the side walls of the sedimentation tank. The commonly used cleaning device is a scraper. To ensure the cleaning effect of the scraper, a certain pressure needs to be applied between the scraper and the side wall, which will cause friction between the scraper and the sedimentation tank wall. Long-term use will cause a gap between the scraper and the sedimentation tank wall, affecting the cleaning effect. Utility Model Content

Both ends of the mounting plate are fixedly connected to a limiting plate, and one end of the T-shaped scraper is fixedly connected to one side of the mounting plate.

[0007] Furthermore, springs distributed at equal intervals are fixedly connected to the other side of the mounting plate, and one end of the spring is fixedly connected to one end of the inner wall of the U-shaped plate.

[0008] Furthermore, there is a gap of 0.5-1 mm between the end of the T-shaped scraper close to the inner wall of the sedimentation tank and the inner wall of the sedimentation tank.

[0009] Furthermore, a mounting cylinder is symmetrically provided on one side of the T-shaped scraper, a rotating shaft is rotatably connected inside the mounting cylinder, a connecting plate is fixedly connected between the two rotating shafts, and the connecting plate is fixedly connected to one end of the auxiliary scraper.

[0010] Furthermore, one end of the rotating shaft is fixedly connected to a torsion spring, and one end of the torsion spring is fixedly connected to one end of the inner wall of the mounting cylinder.

[0011] Furthermore, the driving component includes a support plate fixedly connected to the top of the sedimentation tank, one end of the support plate is fixedly connected to a reduction motor, the output shaft of the reduction motor is fixedly connected to a drive shaft, the bottom end of the drive shaft is fixedly connected to the drive shaft, the bottom end of the drive shaft is fixedly connected to a splint, and the splint is fixedly connected to the middle of the beam.

DETAILED DESCRIPTION

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0020] like Figure 1-3 As shown, a chemical precipitation device for lithium carbonate production includes a sedimentation tank 1 and a cleaning component 2, the cleaning component 2 is rotatably connected to the inside of the sedimentation tank 1, and a driving component 3 for driving the cleaning component 2 to rotate is provided at the top of the sedimentation tank 1. The cleaning component 2 includes a crossbeam 21, and both ends of the crossbeam 21 are fixedly connected to a U-shaped plate 22. One end of the U-shaped plate 22 is provided with a T-shaped scraper 23 for scraping lithium carbonate precipitates on the inner wall of the sedimentation tank 1, and one side of the T-shaped scraper 23 is provided with an auxiliary scraper 24, and one end of the auxiliary scraper 24 is connected to the inner wall of the sedimentation tank 1. The inner wall of the sedimentation tank 1 is in contact connection, and the driving component 3 includes a support plate 31 fixedly connected to the top of the sedimentation tank 1, one end of the support plate 31 is fixedly connected to the reduction motor 32, the output shaft of the reduction motor 32 is fixedly connected to the drive shaft 33, the bottom end of the drive shaft 33 is fixedly connected to the drive shaft 33, the bottom end of the drive shaft 33 is fixedly connected to the splint 34, the splint 34 is fixedly connected to the middle of the beam 21, and there is a gap of 0.5-1 mm between the end of the T-shaped scraper 23 close to the inner wall of the sedimentation tank 1 and the inner wall of the sedimentation tank 1.

[0021] According to the above structure, when in use, the raw liquid for producing lithium carbonate is injected into the interior of the sedimentation tank 1, and the liquid is precipitated inside the sedimentation tank 1. After precipitation, the liquid is discharged, and the precipitated solids are discharged through the bottom end of the sedimentation tank 1. The solids adhered to the inner wall of the sedimentation tank 1 are scraped and cleaned by the cleaning component 2. During cleaning, the drive shaft 33 is driven to rotate clockwise by the reduction motor 32, and the transmission beam 21 passing through the clamping plate 34 rotates clockwise. After the beam 21 rotates, it drives the T-shaped scraper 23 and the auxiliary scraper 24 to rotate. The T-shaped scraper 23 scrapes most of the solids in front of the auxiliary scraper 24, and there is no contact between the T-shaped scraper 23 and the inner wall of the sedimentation tank 1, and no friction is generated, thereby improving the service life of the device.

[0022] like Figure 3 As shown, the top of the U-shaped plate 22 is provided with a slide groove 25 that passes through the U-shaped plate 22, and the interior of the slide groove 25 is slidably connected to a mounting plate 26, both ends of the mounting plate 26 are fixedly connected to a limit plate 27, one end of the T-shaped scraper 23 is fixedly connected to one side of the mounting plate 26, and the other side of the mounting plate 26 is fixedly connected to equidistantly distributed springs 28, and one end of the spring 28 is fixedly connected to one end of the inner wall of the U-shaped plate 22.

[0023] According to the above structure, the T-shaped scraper 23 is fixedly connected to one end of the chute 25, and a spring 28 is provided between the chute 25 and the inner wall of the U-shaped plate 22. When relatively firm solid objects are attached to the side wall of the sedimentation tank 1, the spring 28 can act as a buffer to prevent the T-shaped scraper 23 from directly and hard impacting the attachment and causing deformation of the end of the T-shaped scraper 23.

[0024] like Figure 3 and 4 As shown, a mounting cylinder 210 is symmetrically provided on one side of the T-shaped scraper 23, and a rotating shaft 211 is rotatably connected inside the mounting cylinder 210. A connecting plate 29 is fixedly connected between the two rotating shafts 211. The connecting plate 29 is fixedly connected to one end of the auxiliary scraper 24, and one end of the rotating shaft 211 is fixedly connected to a torsion spring 212. One end of the torsion spring 212 is fixedly connected to one end of the inner wall of the mounting cylinder 210.

[0025] According to the above structure, under the torsion force of the torsion spring 212, the rotating shaft 211 rotates to drive the connecting plate 29 and the auxiliary scraper 24 connected to the side wall of the connecting plate 29 to rotate counterclockwise until one end of the auxiliary scraper 24 contacts the side wall of the sedimentation tank 1. When the auxiliary scraper 24 is driven by the crossbeam 21 to rotate clockwise, the auxiliary scraper 24 cleans the side wall of the sedimentation tank 1. Since most of the attachments on the side wall of the sedimentation tank 1 are removed by the T-shaped scraper 23 in front, the auxiliary scraper 24 can easily scrape off the remaining attachments. Therefore, the torsion spring 212 does not need to use a large torsion force to twist the auxiliary scraper 24, reducing the pressure between the end of the auxiliary scraper 24 and the side wall of the sedimentation tank 1 and reducing wear. Under the action of the torsion spring 212, when the auxiliary scraper 24 is worn, its end can still contact the side wall of the sedimentation tank 1, without affecting the cleaning effect.

[0026] The working principle of the present invention is as follows: when in use, the raw liquid for producing lithium carbonate is injected into the interior of the sedimentation tank 1, and the liquid is precipitated inside the sedimentation tank 1. After precipitation, the liquid is discharged, and the precipitated solids are discharged through the bottom end of the sedimentation tank 1. The solids adhered to the inner wall of the sedimentation tank 1 are scraped and cleaned by the cleaning component 2. During cleaning, the drive shaft 33 is driven to rotate clockwise by the reduction motor 32, and the transmission crossbeam 21 passing through the splint 34 rotates clockwise. After the crossbeam 21 rotates, it drives the T-shaped scraper 23 and the auxiliary scraper 24 to rotate. The T-shaped scraper 23 scrapes most of the solids in front of the auxiliary scraper 24, and there is no contact between the T-shaped scraper 23 and the inner wall of the sedimentation tank 1 and no friction is generated, thereby improving the service life of the device. Under the torsion of the torsion spring 212, the rotating shaft 211 rotates to drive the connecting plate 29 and the auxiliary scraper connected to the side wall of the connecting plate 29. The scraper 24 rotates back until one end of the auxiliary scraper 24 contacts the side wall of the sedimentation tank 1. When the auxiliary scraper 24 is driven by the cross beam 21 to rotate clockwise, the auxiliary scraper 24 cleans the side wall of the sedimentation tank 1. Since most of the attachments on the side wall of the sedimentation tank 1 are removed by the T-shaped scraper 23 in front, the auxiliary scraper 24 can easily scrape off the remaining attachments. Therefore, the torsion spring 212 does not need to use a large torque to twist the auxiliary scraper 24, reducing the pressure between the end of the auxiliary scraper 24 and the side wall of the sedimentation tank 1 and reducing wear. The T-shaped scraper 23 is fixedly connected to one end of the chute 25, and a spring 28 is provided between the chute 25 and the inner wall of the U-shaped plate 22. When there are relatively firm solid objects attached to the side wall of the sedimentation tank 1, the spring 28 can play a buffering role to prevent the T-shaped scraper 23 from directly and hard impacting the attachments and causing deformation of the end of the T-shaped scraper 23.

[0027] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
