Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte filtration, in particular to an electrolyte filtration device. Background Art

[0002] After long-term use of the electrolyte dissolution process, the electrolyte often carries various insoluble impurities and metal particles. Since the electrolyte is recycled by an electric pump, the remaining impurities will not only seriously affect the processing quality, but also seriously affect the circulation speed of the electrolyte. In severe cases, it will even block the electric pump, and once blocked, it is often very difficult to clean. Existing electrolyte filtration devices often use filter elements as filtering components. However, after long-term use, particulate matter will be adsorbed and remain on the filter element, making the filtering effect of the filter element worse. Therefore, it is necessary to clean or replace the filter element regularly. Most filtering devices have a backwashing function, but during the backwashing process, the electrolyte will also be discharged as the backwashing liquid, resulting in waste of the electrolyte. Content of the Utility Model

[0003] The purpose of the utility model is to provide an electrolyte filtration device to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An electrolyte filtration device, including a filtration tank, a water inlet pipe is connected and arranged on the left side of the filtration tank, a water outlet pipe is connected and arranged on the right side of the filtration tank, a backwashing mechanism is arranged inside the filtration tank, and a filter element is arranged inside the filtration tank;

[0005] The backwashing mechanism includes a first motor, a cylinder, and a sewage discharge pipe. The first motor is fixedly installed on the top of the filtration tank. The output end of the first motor is fixedly installed with a first rotating shaft. The first rotating shaft passes through the top of the filtration tank through a bearing. The bottom end of the first rotating shaft is fixedly installed with a lower fixing plate.

The filter element is fixedly installed on the lower fixing plate. The inside of the filter element is communicated with the through holes on the lower fixing plate. The cylinder is fixedly installed on the outer wall of the filtration tank. The extending end of the cylinder is fixedly installed with a connecting frame. The bottom of the connecting frame is fixedly installed with a shielding cover. The shielding cover covers one filter element. The inner wall of the connecting frame is rotationally connected with a backwashing pipe through a bearing. The lower half of the backwashing pipe is located inside the shielding cover. Drainage holes are opened on the outer wall of the lower half of the backwashing pipe. The top end of the backwashing pipe is communicated with a rotary joint. The top end of the rotary joint is communicated with a hose. The top end of the sewage discharge pipe is attached to the lower surface of the lower fixing plate. The top end of the sewage discharge pipe is located directly below the shielding cover. The bottom end of the sewage discharge pipe extends outside the filtration tank.

[0006] Furthermore, a solenoid valve is provided at the top end of the sewage pipe, and the top end of the sewage pipe is not fixedly connected to the lower fixed plate.

[0012] 1. The filter element is driven to rotate by the rotatable lower fixed plate to switch the filter element to be backwashed. After a filter element is aligned with the top of the sewage pipe, the shielding cover falls to cover the filter element to separate the filter element from the external electrolyte. Then, clean water is introduced into the backwashing pipe through a hose and then discharged from the drainage hole on the backwashing pipe to backwash the filter element. The sewage after backwashing is discharged from the sewage pipe. The connecting frame is driven to rise and fall by the cylinder, thereby driving the shielding cover to rise and fall. That is, when switching the filter element, the shielding cover will not hinder the filter element from making a circular motion.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1-6 , the present utility model provides a technical solution: an electrolyte filtering device, including a filter tank 1, a water inlet pipe 2 is communicatively connected to the left side of the filter tank 1, a water outlet pipe 3 is communicatively connected to the right side of the filter tank 1, a backwashing mechanism 4 is arranged inside the filter tank 1, and a filter element 5 is arranged inside the filter tank 1;

[0023] The backwashing mechanism 4 includes a first motor 401, a cylinder 404, and a sewage discharge pipe 408. The first motor 401 is fixedly installed on the top of the filter tank 1. The output end of the first motor 401 is fixedly installed with a first rotating shaft 402. The first rotating shaft 402 passes through the top of the filter tank 1 through a bearing. The bottom end of the first rotating shaft 402 is fixedly installed with a lower fixing plate 403. The lower fixing plate 403 is rotationally connected to the inner wall of the filter tank 1 through a sealing bearing. Through holes are formed in the lower fixing plate 403. The filter element 5 is fixedly installed on the lower fixing plate 403. The inside of the filter element 5 is communicated with the through holes on the lower fixing plate 403. The cylinder 404 is fixedly installed on the outer wall of the filter tank 1. The extending end of the cylinder 404 is fixedly installed with a connecting frame 405. The bottom of the connecting frame 405 is fixedly installed with a shielding cover 406. The shielding cover 406 covers one filter element 5. The inner wall of the connecting frame 405 is rotationally connected with a backwashing pipe 407 through a bearing. The lower half of the backwashing pipe 407 is located inside the shielding cover 406. Drain holes 4010 are formed in the outer wall of the lower half of the backwashing pipe 407. The top end of the backwashing pipe 407 is communicated with a rotary joint 409. The top end of the rotary joint 409 is communicated with a hose. The top end of the sewage discharge pipe 408 is attached to the lower surface of the lower fixing plate 403. The top end of the sewage discharge pipe 408 is located directly below the shielding cover 406. The bottom end of the sewage discharge pipe 408 extends outside the filter tank 1. The filter element 5 is driven to rotate by the rotatable lower fixing plate 403 for switching the filter element 5 to be backwashed. After one filter element 5 is aligned with the top end of the sewage discharge pipe 408, the shielding cover 406 descends to cover the filter element 5, separating the filter element 5 from the external electrolyte. Then, clean water is introduced into the backwashing pipe 407 through the hose and then discharged from the drain holes 4010 on the backwashing pipe 407 to backwash the filter element 5. The sewage after backwashing is discharged from the sewage discharge pipe 408. The connecting frame 405 is driven to rise and fall by the cylinder 404, thereby driving the shielding cover 406 to rise and fall. That is, when switching the filter element 5, the rising of the shielding cover 406 will not interfere with the circular motion of the filter element 5. The backwashing process uses clean water for backwashing, with less waste of electrolyte and no pollution of the electrolyte by the clean water;

[0024] A solenoid valve is provided at the top end of the sewage discharge pipe 408. The top end of the sewage discharge pipe 408 is not fixedly connected to the lower fixing plate 403. The solenoid valve is provided to open and close the sewage discharge pipe 408. That is, when backwashing is not performed, the electrolyte in the filter element 5 will not flow out from the sewage discharge pipe 408. Since the top end of the sewage discharge pipe 408 is not fixedly connected to the lower fixing plate 403, the sewage discharge pipe 408 will not move when the lower fixing plate 403 rotates, ensuring that the sewage discharge pipe 408 is always aligned with the shielding cover 406;

[0025] A brush 8 is fixedly installed on the outer wall of the backwashing pipe 407. The brush 8 is located on the outer wall of the lower half of the backwashing pipe 407. There are three brushes 8, and they are circumferentially arranged in an array on the backwashing pipe 407. During the process of the backwashing pipe 407 extending into the filter element 5, the brush 8 can clean the inner wall of the filter element 5, accelerating the cleaning of the filter element 5;

[0026] A second motor 10 is fixedly installed at the top of the connecting frame 405. A second rotating shaft 11 is fixedly installed at the output end of the second motor 10. The second rotating shaft 11 is drivingly connected to the backwash pipe 407 through a pulley group. By driving the second rotating shaft 11 to rotate by the second motor 10, the backwash pipe 407 is driven to rotate. The rotation of the backwash pipe 407 drives the brush 8 to rotate. The rotating brush 8 can accelerate the cleaning of the inner wall of the filter element 5.

[0027] A rubber ring 6 is fixedly installed at the top of the lower fixed disk 403. The rubber ring 6 is sleeved on the bottom end of the filter element 5. The bottom end of the shielding cover 406 presses on the rubber ring 6. The rubber ring 6 is provided to ensure the sealing effect of the internal space when the shielding cover 406 covers the filter element 5, and prevent the backwashed purified water from entering the filter tank 1.

[0028] A water level ring 7 is fixedly installed on the inner wall of the filter tank 1. A liquid level sensor 9 is fixedly installed on the inner side of the water level ring 7. The water level ring 7 is provided to display the maximum liquid level and prevent the electrolyte in the filter tank 1 from overflowing the filter element 5. The liquid level sensor 9 is provided to detect the liquid level of the electrolyte in the filter tank 1.

[0029] Working principle: When in use, the electrolyte to be filtered is introduced into the filter tank 1 from the water inlet pipe 2. The electrolyte enters the filter element 5 through the through holes on the lower fixed disk 403, and the particulate matter in it is filtered out by the filter element 5, and then discharged from the water outlet pipe 3. When the filter element 5 needs to be backwashed, the air cylinder 404 is opened to drive the connecting frame 405 to move downward. The downward movement of the connecting frame 405 drives the shielding cover 406 to move downward, so that the shielding cover 406 covers the corresponding filter element 5, forming a space isolated from the electrolyte. As the shielding cover 406 covers the filter element 5, the backwash pipe 407 extends into the filter element 5, and the purified water is introduced into the backwash pipe 407 from the hose. The purified water flows out from the drain hole 4010 to wash the inner wall of the filter element 5. At the same time, the second motor 10 is turned on to drive the second rotating shaft 11 to rotate. The rotation of the second rotating shaft 11 drives the backwash pipe 407 to rotate. The rotation of the backwash pipe 407 drives the brush 8 to rotate, so that the brush 8 cleans the inner wall of the filter element 5, improving the cleaning efficiency of the filter element 5. The solenoid valve at the end of the sewage discharge pipe 408 is opened, so that the backwashed sewage is discharged from the sewage discharge pipe 408. After one filter element 5 is cleaned, the air cylinder 404 is opened to drive the connecting frame 405 to rise. At the same time, the solenoid valve on the sewage discharge pipe 408 is closed, and the first motor 401 is turned on to drive the first rotating shaft 402 to rotate, thereby driving the lower fixed disk 403 to rotate. The rotation of the lower fixed disk 403 drives the filter element 5 to move, for switching to the next filter element 5 to be cleaned.

[0030] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
