Description

Technical Field

[0001] This utility model relates to the field of lithium carbonate preparation and filtration technology, and more specifically, to a filtration device for lithium carbonate preparation. Background Technology

[0002] Lithium carbonate is widely used in glass ceramics, new energy vehicles, alloys, and pharmaceuticals. In recent years, the new energy industry has developed rapidly, most notably the lithium battery industry. Cathode materials such as lithium cobalt oxide, lithium nickel oxide, lithium nickel cobalt oxide, lithium iron phosphate, and lithium nickel cobalt manganese oxide are mostly made from lithium carbonate. Existing devices are not convenient for disassembling and cleaning the filter plates. After long-term use, impurities will clog the filter pores, thus affecting the overall filtration effect.

[0003] To address the above issues, application number 202322213723.7, entitled "A Filter for Lithium Carbonate Preparation," describes a filter comprising a housing with a feed hopper on the top left side, a filter screen plate inclinedly arranged inside the housing, a first discharge hopper and a second discharge hopper on the right side of the housing, disassembly and assembly components on both sides of the filter screen plate, and a striking component at the bottom left side of the filter screen plate. This utility model relates to the technical field of lithium carbonate production and processing equipment. This lithium carbonate preparation filter, through the design of the striking component, improves the cleaning efficiency of the filter screen plate, avoids clogging, and ensures the normal operation of the filtration equipment. Simultaneously, the positioning and limiting design ensures the stability of the striking effect, further improving the reliability and performance of the equipment. The disassembly and assembly component design makes the disassembly and installation of the filter screen plate simpler and more effective, improving the ease of maintenance and thus achieving a better filtration effect.

[0004] Although the device has many beneficial effects, it still has the following problems: The device has certain design ideas for easy disassembly of the filter screen and cleaning of the filter screen by tapping component, which aims to reduce filter screen clogging. However, it has revealed obvious limitations in practical application. As for the tapping component, it can only tap on specific areas. This fixed-point tapping mode is difficult to achieve a uniform and comprehensive effect on the entire filter screen. Areas slightly farther away from the tapping point often cannot obtain effective tapping force, making it difficult to effectively shake off the impurities in these areas. As a result, the overall cleaning efficiency of the filter screen is greatly reduced, which seriously hinders the smooth operation of the device and brings many inconveniences and troubles to the actual production process.

[0005] Furthermore, although the device can perform filtration and separation operations on lithium carbonate solutions, it has significant shortcomings in the filtration and treatment of impurities and solutions. After the filtration process is completed, a large amount of solution remains inside the impurities, clearly demonstrating that the device's filtration and separation efficiency is far from ideal. These solutions retained in the impurities actually contain many usable resources. Their presence not only means a serious loophole in raw material recovery, causing reusable lithium and other related substances to be lost with the solution, resulting in direct material waste, but also, from a process cost perspective, this part of the solution that has not been effectively separated increases the complexity and volume of subsequent processing steps. For example, when transferring, storing, or further processing the impurities, the extra weight of the solution will consume more manpower, material resources, and energy, indirectly increasing the overall production cost and having an extremely adverse impact on the economic benefits and resource utilization rate of the entire lithium carbonate production industry.

[0006] In view of this, we propose a filtration device for lithium carbonate preparation. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] The purpose of this invention is to provide a filtration device for lithium carbonate preparation, so as to solve the problems mentioned in the background art.

[0009] 2. Technical Solution

[0010] A filtration device for lithium carbonate preparation includes a fixed platform, a water storage tank on the front outer wall of the fixed platform, a controller on the front outer wall of the water storage tank, an ultrasonic generator on the side wall of the water storage tank, a cleaning assembly on the top of the fixed platform, the cleaning assembly including a fixing frame, a fixed barrel inside the fixed platform, a connecting plate on the inner wall of the fixed barrel, a filter barrel connected to the end of the connecting plate, and an electric telescopic rod at the bottom of the inner cavity of the fixed barrel.

[0011] Preferably, the top of the water storage tank is equipped with a water pump and a water inlet, and the output end of the water pump is connected to a water delivery pipe.

[0012] Preferably, the bottom of the fixed frame is provided with an electric push rod, and the output end of the electric push rod is connected to a movable ring.

[0013] Preferably, the inner wall of the movable ring is provided with a water spray nozzle, the end of the water supply pipe is connected to the top of the movable ring, the inner wall of the movable ring is also provided with a vibrating ring, the vibrating ring is provided with an ultrasonic transducer electrically connected to the ultrasonic generator, and the inner wall of the vibrating ring is in contact with the outer circumference of the filter barrel.

[0014] Preferably, the output end of the electric telescopic rod extends into the interior of the filter barrel and is connected to a compression disc, and a drain pipe is provided at the bottom of the filter barrel.

[0015] Preferably, the top of the filter barrel is connected to a sealing cover plate by a pin, the top of the sealing cover plate is threaded with a sealing plug, the top of the sealing cover plate is also threaded with a fixing bolt, and the top of the filter barrel has a fixing hole that matches the fixing bolt.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are as follows: When cleaning the filter canister is required, the electric push rod can be activated first. The electric push rod operates, driving the movable ring to begin its downward stroke. During this process, the ultrasonic transducer can be activated, causing the vibrating ring to generate high-frequency vibration. During the descent, the movable ring can continuously vibrate along the outer circumference of the filter canister with the help of ultrasonic vibration, thereby forming a uniform and stable vibration wave. This vibration mode can fully cover the outer surface of the filter canister, causing impurities on the filter surface to loosen and fall off under the vibration, effectively preventing and reducing the clogging of the filter port on the outer wall of the filter canister, and maintaining the high-efficiency filtration performance of the filter canister. If a deep cleaning of the filter canister is required, the water pump can be activated further. The water pump delivers cleaning water to the area between the vibrating ring and the movable ring. At this time, under the dual action of strong ultrasonic vibration and high-pressure water flow impact, stubborn dirt on the surface of the filter canister and at the filter port is powerfully peeled off and removed. Compared with traditional cleaning methods, the thoroughness and cleanliness of the cleaning are significantly improved.

[0018] After the lithium carbonate solvent filtration process is completed, the electric telescopic rod can be activated. The electric telescopic rod extends smoothly, pushing the extrusion disc upward. At the same time, the sealing cover fits tightly, forming an encirclement around the filtered impurities, thereby causing the solvent remaining inside the impurities to be fully squeezed out. This extrusion operation greatly reduces the waste caused during lithium carbonate filtration, and the tightly squeezed impurities are also easier to transport or process later.

[0026] Please see Figure 1-3 This utility model provides a technical solution:

[0027] A filtration device for lithium carbonate preparation includes a fixed platform 100, a water storage tank 110 disposed on the outer front wall of the fixed platform 100, a controller 112 disposed on the outer front wall of the water storage tank 110, an ultrasonic generator 113 disposed on the side wall of the water storage tank 110, a cleaning assembly disposed on the top of the fixed platform 100, the cleaning assembly including a fixed frame 200, a fixed bucket 300 disposed inside the fixed platform 100, a connecting plate 310 disposed on the inner wall of the fixed bucket 300, a filter bucket 320 connected to the end of the connecting plate 310, and an electric telescopic rod 330 disposed at the bottom of the inner cavity of the fixed bucket 300.

[0028] In some embodiments, the ultrasonic generator 113 mainly consists of a signal generator, a power amplifier, and a matching circuit. The signal generator generates an electrical signal of a specific frequency through digital or analog circuits. This signal serves as the basic driving source. The power amplifier amplifies the weak signal generated by the signal generator to provide it with sufficient energy. The matching circuit is responsible for adjusting the impedance of the output signal to ensure that the electrical signal can be transmitted smoothly and efficiently to the ultrasonic transducer, thereby providing a suitable and stable electrical drive for the ultrasonic transducer 240 to generate corresponding ultrasonic vibrations. All of the above belong to the prior art.

[0029] Specifically, the top of the water storage tank 110 is equipped with a water pump 111 and a water inlet 114. The output end of the water pump 111 is connected to a water delivery pipe to facilitate the delivery of cleaning water.

[0030] Furthermore, an electric push rod 210 is provided at the bottom of the fixed frame 200, and a movable ring 220 is connected to the output end of the electric push rod 210, which facilitates the movement of the movable ring 220 along the outer circumference of the filter barrel 320.

[0031] Furthermore, a water spray nozzle 250 is provided on the inner wall of the movable ring 220, and the end of the water supply pipe is connected to the top of the movable ring 220. A vibration ring 230 is also provided on the inner wall of the movable ring 220. An ultrasonic transducer 240 electrically connected to the ultrasonic generator 113 is provided inside the vibration ring 230. The inner wall of the vibration ring 230 is in contact with the outer circumference of the filter barrel 320, which facilitates the cleaning of impurities in the outer circumference of the filter barrel 320 and the filter holes.

[0032] Furthermore, the output end of the electric telescopic rod 330 extends into the filter barrel 320 and is connected to a squeezing disc 340. A drain pipe 350 is provided at the bottom of the filter barrel 320, which facilitates the squeezing disc 340 to squeeze the impurities filtered out, thereby reducing the residue of the solvent inside.

[0033] It is worth noting that the top of the filter canister 320 is connected to a sealing cover 360 by a pin. A sealing plug 370 is threaded onto the top of the sealing cover 360, and a fixing bolt 380 is also threaded onto the top of the sealing cover 360. The top of the filter canister 320 has a fixing hole that matches the fixing bolt 380, which facilitates sealing the top of the filter canister 320.

[0034] In some embodiments, the device can be powered by an external conventional power source.

[0035] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0036] Working Principle: When cleaning the filter canister is required, the electric push rod 210 is activated first. The electric push rod 210 operates, driving the movable ring 220 to begin its descent. During this process, the ultrasonic transducer is activated, causing the vibrating ring 230 to generate high-frequency vibration. During its descent, the movable ring 220, aided by the ultrasonic vibration, continuously vibrates along the outer circumference of the filter canister 320, forming a uniform and stable vibration wave. This vibration pattern fully covers the outer surface of the filter canister 320, causing impurities on the filter surface to loosen and fall off under the vibration, effectively preventing and reducing clogging of the filter openings on the outer wall of the filter canister 320, maintaining the filter canister's high-efficiency filtration performance. If a deeper cleaning of the filter canister 320 is required, the water pump 111 can be activated. The cleaning water is delivered to the area between the vibrating ring 230 and the moving ring 220. Under the dual action of strong ultrasonic vibration and high-pressure water flow, stubborn dirt on the surface of the filter barrel 320 and at the filter port is powerfully peeled off and removed. Compared with traditional cleaning methods, the thoroughness and cleanliness of the cleaning are significantly improved. After the lithium carbonate solvent filtration process is completed, the electric telescopic rod 330 can be activated. The electric telescopic rod 330 extends smoothly and pushes the extrusion plate 340 upward. At the same time, the sealing cover 360 fits tightly, forming an encirclement around the filtered solid, thereby causing the solvent remaining inside the solid to be fully squeezed out. Through this extrusion operation, the waste caused by lithium carbonate filtration is greatly reduced, and the tightly squeezed impurities are also easier to transport or process later.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
