[0027] 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.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] A high-salt wastewater treatment filtration and anti-clogging structure includes a base 1, a treatment box 2 fixedly connected to the top of the base 1, a filter assembly 4 disposed inside the treatment box 2, and a backwashing assembly 5 disposed on the rear side of the filter assembly 4.

[0030] The filter assembly 4 includes an outer cylinder 401 bolted inside the processing tank 2, an inner cylinder 402 fixedly connected inside the outer cylinder 401, a drive motor 403 sealed and fixedly connected to the top of the processing tank 2, a rotating shaft 404 fixedly connected to the bottom of the drive motor 403, an agitator 405 fixedly connected to the outside of the rotating shaft 404, a telescopic connecting rod 406 fixedly connected to the bottom of the rotating shaft 404, a scraper 407 fixedly connected to the outside of the telescopic connecting rod 406, a drain pipe 408 connected to the bottom of the inner cylinder 402, and a drain pipe 409 connected to the bottom of the outer cylinder 401.

[0031] In this embodiment: by starting the drive motor 403, the motor drives the rotating shaft 404 to rotate, and then the stirring blades 405 on the rotating shaft 404 rotate accordingly, stirring the high-salt wastewater and promoting the uniform dispersion of impurities in the wastewater, which is convenient for subsequent filtration. At the same time, the rotating shaft 404 drives the telescopic connecting rod 406 and the scraper 407 to rotate. During the rotation, the scraper 407 can scrape off the impurities adhering to the surface of the filter medium in the inner cylinder 402, preventing excessive accumulation of impurities and blockage. During the filtration process, the clean water filtered by the filter medium in the inner cylinder 402 will flow into the outer cylinder 401 through the filter holes of the inner cylinder 402, and finally be discharged through the drain pipe 409 connected to the bottom of the outer cylinder 401, achieving preliminary filtration. The impurities intercepted by the filter medium will enter the sewage tank 12 through the sewage pipe 408. The sewage valve 11 on the outside of the sewage pipe 408 can control the discharge of impurities. The collection box 13 in the sewage tank 12 is used to collect impurities for subsequent cleaning.

[0032] Specifically, such as Figure 3 As shown, a backwash water tank 501 is bolted to the rear side of the treatment tank 2, a top cover 502 is snapped onto the top of the backwash water tank 501, and a liquid level sensor 503 is electrically connected to the top of the backwash water tank 501.

[0033] Specifically, such as Figure 3As shown, a high-pressure water pump 504 is fixedly connected to the top of the backwash water tank 501. The inlet of the high-pressure water pump 504 is connected to the interior of the backwash water tank 501, and the output of the high-pressure water pump 504 is connected to a delivery pipe 505.

[0034] Specifically, such as Figure 3 As shown, the outer side of the delivery pipe 505 is connected to the return water pipe 506, which is bolted to the inside of the outer cylinder 401. The outer side of the return water pipe 506 is connected to the backwash nozzle 507.

[0035] In this embodiment: when backwashing is required, first open the top cover 502 and add backwash water to the backwash water tank 501. The level sensor 503 can monitor the water level in the backwash water tank 501 in real time. Then, start the high-pressure water pump 504, which pressurizes the water in the backwash water tank 501. The pressurized water then enters the return water pipe 506 through the delivery pipe 505. The backwash nozzle 507 connected to the return water pipe 506 will spray the high-pressure backwash water in a pulse form onto the surface of the filter medium in the inner cylinder 402. The impact force of the pulse water flow is strong, which can effectively remove the impurities remaining on the surface and in the pores of the filter medium, restore the filter medium to good filtration performance, and avoid the filtration efficiency and effect being affected by impurities clogging.

[0036] Specifically, such as Figure 1 , Figure 4 As shown, the top of the treatment tank 2 is connected to the water inlet pipe 6, the top of the base 1 is connected to the ultrafiltration device 7, the ultrafiltration device 7 is connected to the water inlet pipe 6, and the top of the base 1 is connected to the multi-effect evaporator 8, the multi-effect evaporator 8 is connected to the ultrafiltration device 7.

[0037] Specifically, such as Figure 6 As shown, an auxiliary spring 9 is bolted inside the telescopic link 406, and a rubber sleeve 10 is bolted to the outside of the telescopic link 406.

[0038] In this embodiment: High-salt wastewater flows into the treatment tank 2 through the inlet pipe 6, ultrafiltration equipment 7, and multi-effect evaporator 8 for preliminary filtration. The pre-filtered water then enters the ultrafiltration equipment 7, which uses a special filter membrane to remove finer impurities, large organic molecules, and some salts. The water from the ultrafiltration equipment 7 then enters the multi-effect evaporator 8. The multi-effect evaporator 8 uses the principle of multi-effect evaporation, employing the secondary steam generated in the previous effect as a heat source for the next effect to evaporate the water. This process continuously vaporizes and separates the water, gradually concentrating and crystallizing the salts, improving water resource utilization, reducing wastewater pollution, and simultaneously obtaining concentrated... The reduction of salt content also facilitates subsequent processing or recycling. By setting an auxiliary spring 9 and a rubber sleeve 10, when the drive motor 403 drives the rotating shaft 404 to rotate, the telescopic connecting rod 406 rotates with the rotating shaft 404. When the scraper 407 contacts the impurities on the surface of the filter medium in the inner cylinder 402, if it encounters great resistance, the auxiliary spring 9 inside the telescopic connecting rod 406 will play a buffering role to prevent the scraper 407 from being damaged due to excessive resistance. At the same time, the rubber sleeve 10 on the outside of the telescopic connecting rod 406 can prevent the telescopic connecting rod 406 from rusting, ensure its normal extension and contraction, and enhance the sealing between the scraper 407 and the inner cylinder 402 to prevent impurities from leaking through the gap between the scraper 407 and the inner cylinder 402.

[0039] Specifically, such as Figure 5 As shown, a drain valve 11 is bolted to the outside of the drain pipe 408, and a drain box 12 is connected to the bottom of the drain pipe 408. A collection box 13 is slidably connected inside the drain box 12.

[0040] Specifically, such as Figure 1 , Figure 4 As shown, a caster wheel 3 is fixedly connected to the bottom of the base 1, and a shock-absorbing seat 14 is bolted inside the base 1.

[0041] In this embodiment: by setting up a drain valve 11, a drain tank 12, and a collection box 13, when impurities filtered out by the inner cylinder 402 enter the drain tank 12 through the drain pipe 408, the drain valve 11 can control the timing and flow rate of impurity discharge. Then, the collection box 13 in the drain tank 12 is used to collect impurities. The drain valve 11 is opened periodically to allow impurities to enter the collection box 13. After the collection box 13 is full, it is pulled out of the drain tank 12 for cleaning. After cleaning, the collection box 13 is put back into the drain tank 12 to facilitate the filtration process. The generated impurities are collected and cleaned in a centralized manner to prevent them from accumulating in the drain pipe 408 or the treatment box 2 and affecting the normal operation of the equipment. By setting up casters 3 and shock absorbers 14, when the equipment needs to be moved, the casters 3 at the bottom of the base 1 can be used to easily push the equipment to the designated position. During the operation of the equipment, the drive motor 403, stirring blades 405 and other components will generate vibrations. The shock absorbers 14 inside the base 1 can absorb and buffer these vibrations, reducing the impact of vibration on the equipment's own structure and the surrounding environment.

[0042] Working Principle: In the process of using the high-salinity wastewater treatment filter anti-clogging structure, the high-salinity wastewater to be treated is first introduced into the treatment tank 2 through the inlet pipe 6. Then, the wastewater enters the inner cylinder 402, which contains the filter media. Next, the drive motor 403 is started, which drives the rotating shaft 404 to rotate. The stirring blades 405 on the rotating shaft 404 then rotate, stirring the high-salinity wastewater and promoting uniform dispersion of impurities, facilitating subsequent filtration. Simultaneously, the rotating shaft 404 drives the telescopic connecting rod 406 and the scraper 407 to rotate, scraping... During rotation, plate 407 scrapes away impurities adhering to the surface of the filter medium in inner cylinder 402, preventing excessive accumulation and clogging. During filtration, the clean water filtered by the filter medium in inner cylinder 402 flows through the filter holes into outer cylinder 401 and is finally discharged through drain pipe 409 connected to the bottom of outer cylinder 401, achieving preliminary filtration. Impurities intercepted by the filter medium enter the drain tank 12 through drain pipe 408. The drain valve 11 on the outside of drain pipe 408 controls the discharge of impurities. The collection box 13 inside the sludge tank 12 is used to collect impurities for subsequent cleaning. When backwashing is required, first open the top cover 502 and add backwash water to the backwash water tank 501. The level sensor 503 can monitor the water level in the backwash water tank 501 in real time. Then, start the high-pressure water pump 504, which pressurizes the water in the backwash water tank 501. The pressurized water then enters the return water pipe 506 through the delivery pipe 505. The backwash nozzle 507 connected to the return water pipe 506 then sprays the high-pressure backwash water... The water is sprayed in a pulsed manner onto the surface of the filter medium in the inner cylinder 402. The impact force of the pulsed water flow is strong, which can effectively remove the impurities remaining on the surface and in the pores of the filter medium, restore the filter medium to good filtration performance, and avoid the filtration efficiency and effect being affected by impurities clogging. Then, the ultrafiltration device 7 can perform deep treatment on the water after preliminary filtration, removing finer impurities and some salts. The multi-effect evaporator 8 then evaporates the water after ultrafiltration, further separating salts and water, realizing the recycling of water resources and the concentration of salts.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
