Description

Technical Field

[0001] This utility model relates to the technical field of pre-treatment equipment for spraying, and more specifically, to an environmentally friendly water tank for pre-treatment of spraying. Background Technology

[0002] In the spraying industry, the pretreatment process is crucial to the quality of spraying. As a key piece of equipment for storing and treating liquids in the pretreatment process, the structural design of the water tank directly affects the treatment effect and environmental performance. In the pretreatment process of spraying, the workpiece usually needs to be cleaned, degreased, and derusted to ensure the quality of spraying.

[0003] Existing pretreatment water tanks for spraying have poor filtration effects and are difficult to effectively remove impurities. At the same time, the aeration treatment of the water is insufficient, and the filter plates are installed inside the filter tank. After long-term use, it is inconvenient to scrape off the blockages on the surface of the filter plates, which can easily lead to clogging and poor filtration.

[0004] Therefore, we have made improvements to this by proposing an environmentally friendly water tank for pre-treatment before spraying. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing pretreatment water tanks for spraying, which have poor filtration effects and are difficult to effectively remove impurities. Furthermore, the aeration of the water is insufficient, and the filter plates are installed inside the filtration tank, making it inconvenient to scrape off surface blockages after prolonged use, which easily leads to filter plate clogging and poor filtration performance.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] An environmentally friendly water tank for pretreatment before spraying is proposed to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] The device includes a water tank body, a base installed at the bottom of the water tank body, and multiple partition plates installed inside the water tank body. From left to right, the partition plates and the interior of the water tank body form a first filtration pool, a second filtration pool, and an impregnation pool. An MBR membrane zone pool is installed on one side of the water tank body. Filter plates are installed on the inner walls of both the first and second filtration pools, and cleaning components are provided on the filter plates.

[0010] A servo motor drives a bidirectional screw to rotate, which in turn moves a moving plate and brushes to scrape the surface of the filter plate. This effectively removes blockages from the filter plate surface, preventing clogging and ensuring the filtration effect and lifespan of the filter plate. It also reduces replacement costs and maintenance workload caused by filter plate clogging. An aeration system consisting of an air compressor, aeration pipes, and aeration discs is installed in the immersion tank to fully aerate the water. Filter plates are installed on the inner wall of each filtration tank for two-stage filtration, effectively removing impurities of different sizes from the water.

[0011] As a preferred embodiment of the pre-treatment environmentally friendly water tank provided by this utility model, the top of the main body of the water tank is provided with observation ports located above the first filter pool, the second filter pool and the immersion pool respectively.

[0012] As a preferred embodiment of the pretreatment environmentally friendly water tank provided by this utility model, an inlet pipe is installed on the top of the first filter tank, a first water passage hole is opened between the first filter tank and the second filter tank at the bottom, a second water passage hole is opened between the second filter tank and the impregnation tank at the top, and a third water passage hole is opened between the impregnation tank and the MBR membrane zone tank at the top.

[0013] In a preferred embodiment of the pretreatment environmentally friendly water tank provided by this utility model, an air compressor is installed at the top of the immersion tank, an aeration disc is installed at the bottom of the immersion tank, and an aeration pipe is installed between the aeration disc and the air compressor.

[0015] In a preferred embodiment of the pre-treatment environmentally friendly water tank provided by this utility model, a first sliding groove is provided on the side of the fixing block, a servo motor is installed on the inner wall of the first sliding groove, and the output shaft of the servo motor is equipped with a bidirectional screw that is rotatably engaged with the inner wall of the first sliding groove.

[0016] As a preferred embodiment of the pre-treatment environmentally friendly water tank provided by this utility model, the inner walls of the first slid groove are slidably fitted with first moving blocks that are threaded with the two sides of the bidirectional screw. The side of the moving plate is provided with a second slid groove. A sliding rod is installed between the inner walls of the two sides of the second slid groove. The inner walls of the second slid groove are slidably fitted with second moving blocks that are slidably fitted with the sliding rod.

[0017] In a preferred embodiment of the pre-treatment environmentally friendly water tank provided by this utility model, a cross-connecting frame is provided between the two first moving blocks and the two second moving blocks, and a rotating shaft is rotatably engaged in the middle of the two connecting frames.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By driving the bidirectional screw to rotate through the servo motor, the moving plate and brush scrape the surface of the filter plate, which can promptly remove the blockage on the surface of the filter plate, avoid filter plate clogging, ensure the filtration effect and service life of the filter plate, and reduce the replacement cost and maintenance workload caused by filter plate clogging. An aeration system consisting of an air compressor, aeration pipe and aeration disc is set in the immersion tank, which can fully aerate the water. Filter plates are installed on the inner wall of each filter tank to perform two-stage filtration of the water, which can effectively remove impurities of different sizes in the water.

[0033] Example 1

[0034] Please refer to Figure 1-4An environmentally friendly water tank for pretreatment before spraying includes: a tank body 1, a base 2 installed at the bottom of the tank body 1, multiple partition plates 3 installed inside the tank body 1, forming a first filtration tank 4, a second filtration tank 5, and an impregnation tank 6 from left to right between the partition plates 3 and the interior of the tank body 1, an MBR membrane zone tank 7 installed on one side of the tank body 1, filter plates 8 installed on the inner walls of both the first filtration tank 4 and the second filtration tank 5, and cleaning components 9 installed on the filter plates 8. The top of the tank body 1 has observation ports 17 located above the first filtration tank 4, the second filtration tank 5, and the impregnation tank 6 respectively. A water inlet pipe 10 is installed at the top of the first filtration tank 4, a first water passage hole 12 is opened at the bottom between the first filtration tank 4 and the second filtration tank 5, a second water passage hole 13 is opened at the top between the second filtration tank 5 and the impregnation tank 6, and a third water passage hole 14 is opened at the top between the impregnation tank 6 and the MBR membrane zone tank 7. An air compressor 11 is installed at the top of the impregnation tank 6, an aeration disc 15 is installed at the bottom of the impregnation tank 6, and an aeration pipe 16 is installed between the aeration disc 15 and the air compressor 11.

[0035] Implementation Process: The water to be treated enters the first filtration tank 4 through the inlet pipe 10. A filter plate 8 is installed on the inner wall of the first filtration tank 4. As the water passes through the filter plate 8, larger impurities are intercepted on one side of the filter plate 8. The water after preliminary filtration flows into the second filtration tank 5 through the first water passage 12 at the bottom between the first filtration tank 4 and the second filtration tank 5. The water entering the second filtration tank 5 undergoes secondary filtration again through the filter plate 8 installed on the inner wall of the tank, further removing fine impurities. After secondary filtration, the water flows into the impregnation tank 6 through the second water passage 13 at the top between the second filtration tank 5 and the impregnation tank 6. After the water flows into the impregnation tank 6, the air compressor 11 is started, and air is delivered to the aeration disc 15 through the aeration pipe 16. The aeration disc 15 disperses the air into the water, aerating the water and increasing the dissolved oxygen content, which is beneficial for subsequent treatment. After impregnation and aeration, the water flows into the MBR membrane zone tank 7 through the third water passage 14 at the top between the impregnation tank 6 and the MBR membrane zone tank 7. The MBR membrane zone tank 7 further filters and purifies the water using an MBR membrane, removing microorganisms, organic matter, and other impurities to obtain cleaner water. The top of the main body of the water tank 1 is equipped with observation ports 17 located above the first filter tank 4, the second filter tank 5, and the immersion tank 6, respectively. Operators can observe the water quality, the clogging of the filter plates 8, and the aeration effect in each tank at any time through the observation ports 17, so as to promptly detect problems and take corresponding measures.

[0036] Benefits of implementation: Installing filter plates 8 on the inner wall of each filter tank allows for two-stage filtration of the water, effectively removing impurities of different sizes from the water.

[0037] Example 2

[0038] The cleaning component 9 includes a fixed block 901 mounted on the filter plate 8. A movable plate 902 is provided on one side of the fixed block 901, and a brush 903 that mates with the filter plate 8 is mounted on the bottom of the movable plate 902. A first groove 904 is formed on the side of the fixed block 901. A servo motor 905 is mounted on the inner wall of the first groove 904. A bidirectional screw 906 is mounted on the output shaft of the servo motor 905 and rotates on the inner wall of the first groove 904. First movable blocks 907 that are threaded on both sides of the inner wall of the first groove 904 are slidably fitted with the threads on both sides of the bidirectional screw 906. A second groove 908 is formed on the side of the movable plate 902. A slide rod 909 is installed between the inner walls of the two sides of the second groove 908. Second movable blocks 910 that are slidably fitted with the slide rod 909 are slidably fitted on both sides of the inner wall of the second groove 908. A cross-connecting frame 911 is provided between the two first moving blocks 907 and the two second moving blocks 910, and a rotating shaft 912 is rotatably engaged in the middle of the two connecting frames 911.

[0039] Implementation Process: When a large amount of impurities adhere to the surface of the filter plate 8, the cleaning assembly 9 is activated. The servo motor 905 starts, driving the bidirectional screw 906 to rotate. Since the threads on both sides of the bidirectional screw 906 are in opposite directions, the first moving block 907, which engages with the threads on both sides of the bidirectional screw 906, moves towards or away from each other within the first slide groove 904. The movement of the first moving block 907 is transmitted to the second moving block 910 through the connecting frame 911, causing the second moving block 910 to slide on the slide rod 909. The connecting frames 911 are arranged crosswise and rotate through the rotating shaft 912 in the middle, thereby causing the moving plate 902 to move closer to or away from the filter plate 8. The brush 903 at the bottom of the moving plate 902 scrapes the surface of the filter plate 8, removing the blockages from the surface of the filter plate 8.

[0040] Benefits of implementation: The brush 903 on the movable plate 902 scrapes the surface of the filter plate 8, which can remove the blockage on the surface of the filter plate 8 in a timely manner.
