Description

Technical Field

[0001] This utility model relates to the technical field of high-salt wastewater treatment equipment, and in particular to a high-salt reverse osmosis treatment device for the lithium battery industry. Background Technology

[0002] In the lithium battery manufacturing industry, with the expansion of production scale and the improvement of process technology, high-salt wastewater is becoming an increasingly common byproduct. This type of wastewater contains high concentrations of salts, heavy metal ions, organic matter, and tiny suspended solids. Direct discharge of such wastewater would cause serious environmental pollution. Reverse osmosis technology, through the selective permeability of semi-permeable membranes, can effectively intercept salts, most organic matter, and colloidal particles in wastewater under high pressure, thereby achieving wastewater purification and salt concentration and recovery.

[0003] However, in existing high-salt reverse osmosis treatment devices, large particulate impurities in the raw water directly enter the reverse osmosis system. Over time, these impurities accumulate on the filter cartridges, causing blockage, reducing their lifespan, and severely impacting water purification efficiency. Furthermore, filter boxes are often fixed with bolts and screws, making equipment maintenance and filter cartridge replacement cumbersome and inefficient. Therefore, a high-salt reverse osmosis treatment device for the lithium battery industry is proposed. Utility Model Content

[0008] As a further description of the above technical solution:

[0019] 1.

The output end of the pressure pump 9 is fixedly connected to the reverse osmosis treatment box 10. The impact force of the water flowing into the filter box 4 drives the water wheel 5 to rotate. The water wheel 5 drives the cleaning brush 7 to rotate through the transmission rod 6, realizing real-time and automatic cleaning of the surface of the filter screen plate 8. This effectively avoids the accumulation of large particles and tiny sediments on the filter screen plate 8 during the wastewater treatment process, thereby ensuring the continuous and efficient filtration capacity of the filter screen plate 8. This not only improves the overall treatment efficiency but also extends the service life of the filter screen plate 8 and reduces the maintenance costs and time consumption caused by frequent replacement of the filter screen plate 8.

[0030] In addition, a reverse osmosis filter element 11 is installed inside the reverse osmosis treatment box 10. A concentrate pipe 12 is fixedly connected to one side of the reverse osmosis treatment box 10, and a first solenoid valve 13 is installed on the concentrate pipe 12. A concentrate tank 14 is fixedly connected to one end of the concentrate pipe 12. A purified water pipe 15 is fixedly connected to the other side of the reverse osmosis treatment box 10, and a second solenoid valve 16 is installed on the purified water pipe 15. A purified water tank 17 is fixedly connected to one end of the purified water pipe 15. A sliding groove 18 is opened on the filter box 4, and a sliding rod 19 is slidably connected in the sliding groove 18. A lock head 20 is fixedly connected to one end of the sliding rod 19, and a spring 21 is sleeved on the sliding rod 19. The two ends of the spring 21 are fixedly connected to the filter box 4 and the lock head 20, respectively. A handle 22 is fixedly connected to the other end of the sliding rod 19. A box cover 23 is slidably connected to the filter box 4, and a connecting rod 2 is fixedly connected to the bottom of the box cover 23. 4. A locking rod 25 is fixedly connected to the connecting rod 24. A sealing ring 26 is provided on the filter box 4. When it is necessary to clean or replace the filter screen 8, pull the handle 22 and release the locking head 20 from the locking rod 25 through the slide rod 19, and quickly open the box cover 23, which improves maintenance efficiency. When closing the box cover 23, the elastic force of the spring 21 is used to achieve quick locking. Combined with the tight fit of the sealing ring 26, leakage during the treatment process is effectively prevented. The operation is simple and the work efficiency is improved. The transmission rod 6 and the cleaning brush 7 both rotate inside the filter box 4. The reverse osmosis filter element 11 is provided in multiple sets and is located between the concentrate pipe 12 and the clean water pipe 15. The slide groove 18 and the slide rod 19 are provided in two sets and are symmetrically distributed on the filter box 4. The locking head 20 and the handle 22 are provided in two sets. The locking head 20 is wedge-shaped and the locking rod 25 is "L"-shaped.

[0031] Working Principle: When using this high-salt reverse osmosis treatment device for the lithium battery industry, the operator puts the wastewater to be treated into the raw water tank 1, and then starts the water pump 3. The water pump 3 draws the wastewater from the raw water tank 1 into the filter box 4 through the water pipe 2. The filter screen 8 performs preliminary filtration, filtering out large particles of impurities in the wastewater within the filter box 4. When the water flows into the filter box 4, it impacts the water wheel 5, causing the water wheel 5 to rotate. The water wheel 5 drives the cleaning brush 7 to rotate through the transmission rod 6. The cleaning brush 7 scrapes away the impurities and deposits attached to the filter screen 8, reducing the impact of dirt on the filtration effect of the filter screen 8. The preliminarily filtered wastewater enters the reverse osmosis treatment tank 10. The high-pressure pump 9 is started to increase the water pressure. When the water pressure is greater than the osmotic pressure inside the reverse osmosis filter element 11, water molecules pass through the membrane pores, while ions, inorganic salts, organic matter, and salts in the wastewater are trapped outside the membrane, thereby purifying the water. Then, the second solenoid valve 16 is opened. Filtered water flows from the purified water pipe 15 into the purified water tank 17. The first solenoid valve 13 is opened, allowing concentrated water to flow through the concentrated water pipe 12 into the concentrated water tank 14 for further processing. When it is necessary to replace the filter screen 8 in the filter box 4 or remove impurities, pulling the two sets of handles 22 causes the handles 22 to drive the lock head 20 via the slide rod 19, thus releasing the lock head 20 from locking the lock rod 25. This allows the box cover 23 to be lifted, opening the filter box 4 for the next operation. After cleaning is complete... The lid 23 is then replaced. As the lid 23 moves downward, it moves the locking rod 25 along with it via the connecting rod 24. The protruding end of the locking rod 25 presses against the inclined end of the locking head 20, while the locking head 20 presses against the spring 21. When the flat end of the locking rod 25 contacts the flat end of the locking head 20, the locking head 20 will return to its original position under the elastic force of the spring 21. Thus, the flat end of the locking head 20 locks the locking rod 25, thereby locking the filter box 4. The sealing ring 26 can be used to seal the filter box and prevent leakage.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
