[0018] Example 1: Refer to Figures 1-6An industrial water treatment device includes a treatment tank 1. The treatment tank 1 is equipped with an inlet pipe 6, an outlet pipe, a feeding channel 9, and a stirring unit 10. A motor 11 is connected to the top of the stirring unit 10. Industrial water is injected and discharged through the inlet pipe 6 and the outlet pipe. Reaction reagents are added to the treatment tank 1 through the feeding channel 9 to cooperate with the stirring unit 10 in treating the industrial water before discharge. A left partition door 3 and a right partition door 4 are slidably installed inside the treatment tank 1. The top and bottom of both the left partition door 3 and the right partition door 4 are connected to water... The horizontally extending electric guide rail 5 allows the left partition door 3 and right partition door 4 to move left and right via the corresponding electric guide rail 5. Both the left partition door 3 and right partition door 4 are equipped with an upper door panel 14 that opens from above and a lower door panel 15 that opens from below. The treatment tank 1 is divided into three chambers from left to right: a first chamber 101, a second chamber 102, and a third chamber 103, by the left partition door 3 and right partition door 4. The second chamber 102 is located between the left partition door 3 and right partition door 4. The stirring unit 10 is located within the second chamber 102. The top of the treatment tank 1 can... The tank cover 2 is detached and connected. An electric guide rail 5, located above the left partition door 3 and right partition door 4, is connected to the tank cover 2. A motor 11 is installed between the tank cover 2 and the motor. The inlet pipe 6 connects to tank cavity one 101, and the outlet pipe connects to tank cavity three 103. Two feeding channels 9 are provided, connecting to tank cavity one 101 and tank cavity two 102 respectively. During use, the left and right movements of the left and right partition doors 3 and 4 in the horizontal direction continuously change the depth of the continuously entering wastewater, thereby improving the contact effect and reaction between the wastewater and the reagent. To improve treatment efficiency, the upper door plate 14 and lower door plate 15 of the left partition door 3 and right partition door 4 move up and down to achieve the flow of wastewater between different tank chambers, and effectively reduce the large amount of sediment or chemicals flowing out with the liquid, thereby improving the efficiency of continuous wastewater treatment and ensuring the effectiveness of wastewater treatment. The outlet pipe is equipped with outlet pipe one 7 and outlet pipe two 8. Outlet pipe one 7 is located above outlet pipe two 8, so that water can be drawn back from the top through outlet pipe one 7 and drained and sludge can be discharged from the bottom through outlet pipe two 8, respectively. Specifically, such as Figure 3 The diagram shows the initial state of the left partition door 3 and the right partition door 4. Both the left partition door 3 and the right partition door 4 are in the middle of the horizontal movement area. At this time, the upper door panel 14 is at the top and fits against the pool cover 2 at the top of the treatment pool 1, and the lower door panel 15 is at the bottom and fits against the bottom of the treatment pool 1, so that the left partition door 3 and the right partition door 4 completely seal the space between the first pool cavity 101 and the second pool cavity 102, as well as the space between the second pool cavity 102 and the third pool cavity 103. In the initial stage of use, quickly move the left partition 3 to the rightmost position of the movable area and the right partition 4 to the leftmost position of the movable area, and then start filling with water; During the water injection process, the upper door panel 14 of the left partition door 3 moves downward and opens, connecting the top areas of the first pool 101 and the second pool 102. The left partition door 3 moves from right to left, while the right partition door 4 moves from left to right. Wastewater is gradually injected into the first pool 101, and the wastewater will initially mix with the agent added to the first pool 101. At the same time, the width of the first pool 101 gradually decreases while water is continuously injected, which will cause the width of the wastewater in the first pool 101 to gradually decrease while the water level gradually increases, until the water at the top of the first pool 101 passes over the left partition door 3 and enters the second pool 102 to mix with the agent. When the left partition door 3 moves to the leftmost end of the movable area and the right partition door 4 moves to the rightmost end of the movable area, the left partition door 3 is closed, and the left partition door 3 moves to the right and the right partition door 4 moves to the left, that is, both the left partition door 3 and the right partition door 4 move towards the middle, and the upper door panel 14 of the right partition door 4 is moved downward to open the top; at this time, the space of the first pool 101 increases and water is continuously filled, and the water filled in the first pool 101 is initially treated and will not flow directly into the second pool 102, while the water level in the second pool 102 gradually rises as the width decreases, and flows over the right partition door 4 into the third pool 103. At this time, the upper outlet pipe 7 is opened but the lower outlet pipe 8 is not opened, so that the water above the third pool 103 is drawn out from the outlet pipe 7 for recycling; After the left partition door 3 moves to the rightmost end of the movable area and the right partition door 4 moves to the leftmost end of the movable area, both the left and right partition doors 3 and 4 turn towards the middle position. The opening states of the left and right partition doors 3 and 4 are set accordingly, thus repeating the cycle. When the wastewater flows out of the first chamber 101, the second chamber 102, and the third chamber 103, the upper part of the water flows out to avoid a large amount of solid impurities being carried out. Furthermore, the opening and closing of the upper door panels 14 of the left and right partition doors 3 and 4 improves the treatment effect of the wastewater, preventing a large amount of wastewater from flowing out of the treatment position before fully contacting the reagents and directly recycling it. This ensures the continuity of treatment and recycling, thereby guaranteeing overall work efficiency. After a period of treatment or once treatment is complete, open the lower door panels 15 of the left partition door 3 and the right partition door 4, and open the outlet pipe 8 to remove and filter out the solid impurities that have settled at the bottom, thereby ensuring the effectiveness of the treatment tank 1 in treating industrial water.

[0019] In this invention, both the left partition door 3 and the right partition door 4 are provided with vertical rods 12 connected to the electric guide rail 5. A horizontal frame 13 is fixed in the middle of the vertical rod 12. The outer wall of the horizontal frame 13 slides in contact with the inner walls of both ends of the treatment tank 1. The upper door panel 14 and the lower door panel 15 are connected to the horizontal frame 13 by springs 16. It should be noted that the upper door panel 14 and the lower door panel 15 are respectively located on both sides of the horizontal frame 13 to slide in contact to ensure the sealing effect of the foundation. The top of the upper door panel 14 and the bottom of the lower door panel 15 are both set as horizontal plates. The horizontal plates are provided with through holes that slide in contact with the vertical rods 12. Under normal conditions, the horizontal plate of the upper door panel 14 slides in contact with the top of the tank cavity, and the horizontal plate of the lower door panel 15 slides in contact with the bottom of the tank cavity, thereby achieving separation and sealing.

[0020] In this invention, magnetic blocks 17 are fixed at positions away from the horizontal plate on both the upper door panel 14 and the lower door panel 15. Electromagnetic blocks 18 corresponding to the positions of magnetic blocks 17 are installed on the horizontal frame 13. When the electromagnetic blocks 18 are energized, they repel each other magnetically, thereby enabling the upper door panel 14 to descend and the lower door panel 15 to rise. It should be noted that, under normal conditions, the bottom position of the upper door panel 14 away from the horizontal plate is located below the horizontal frame 13, while the top position of the lower door panel 15 away from the horizontal plate is located above the horizontal frame 13. Therefore, the magnetic blocks 17 of both the upper door panel 14 and the lower door panel 15 are in positions close to the horizontal frame 13. Thus, when the electromagnetic blocks 18 are energized, they generate magnetic repulsion with the corresponding magnetic blocks 17, thereby enabling the upper door panel 14 to descend and the lower door panel 15 to rise.

[0021] An industrial water treatment method includes the following steps: Step 1, Initial state: Both the left partition 3 and the right partition 4 are in the middle of the horizontal movement area, so that the left partition 3 blocks the space between pool 1 101 and pool 2 102, and the partition 4 blocks the space between pool 2 102 and pool 3 103. Step 2: Quickly move the left partition door 3 to the far right and the right partition door 4 to the far left, then start filling with water; Step 3: During the water filling process, the upper door panel 14 of the left partition door 3 moves downward and opens, connecting the top areas of the first pool 101 and the second pool 102. The left partition door 3 moves from right to left, while the right partition door 4 moves from left to right, until the left partition door 3 moves to the leftmost end and the right partition door 4 moves to the rightmost end, allowing the water in the first pool 101 to enter the second pool 102. Step 4: Close the left partition door 3, and move the left partition door 3 to the right and the right partition door 4 to the left. Move the upper door panel 14 of the right partition door 4 downward to open the top, until the left partition door 3 moves to the rightmost end and the right partition door 4 moves to the leftmost end, so that the water in the second pool 102 enters the third pool 103. Step 5: Repeat the process between Step 3 and Step 4.

[0022] Example 2: Refer to Figures 1-6 An industrial water treatment device, based on Embodiment 1, has multiple guide members 19 on both sides of the lower door panel 15. The guide members 19 extend horizontally and are equipped with multiple fixed blocks 20 and movable blocks 21. The fixed blocks 20 are fixedly connected to the lower door panel 15, and the movable blocks 21 are connected to the lower door panel 15 by a spring 22. It should be noted that the fixed blocks 20 and movable blocks 21 are spaced apart horizontally, and the side of the movable block 21 is provided with a sliding groove. The inner wall of the groove slides in contact with the outer wall of the fixed block 20, so that the movable block 21 can move stably in the direction perpendicular to the plate surface of the lower door panel 15. Thus, during the reciprocating movement of the left partition door 3 and the right partition door 4, the movable block 21 will be displaced relative to the fixed block 20 under the action of inertia, thereby improving the dispersion and guiding effect of wastewater in the pool cavity, and thus improving the working efficiency of contact treatment between wastewater and reagents.

[0023] Example 3: Based on Example 1 or Example 2, referring to... Figures 1-8 An industrial water treatment device includes a stirring unit 10 with an upper shaft 23, a middle shaft 24, and a lower shaft 25 arranged sequentially from top to bottom. The top end of the upper shaft 23 is connected to the output shaft of a motor 11. Multiple stirring blades 27 are fixed to the outer wall of the middle shaft 24. A shaft seat 26 is installed at the bottom of the treatment tank 1. The outer wall of the lower shaft 25 is rotatably connected to the shaft seat 26 via bearings. A rectangular sliding rod 28 is fixed at the middle position of the middle shaft 24. Sliding grooves are provided at the bottom end of the upper shaft 23 and the top end of the lower shaft 25. The outer wall of the sliding rod 28 is slidably connected to the inner wall of the sliding groove. Springs are connected to the top and bottom ends of the sliding rod 28. Connecting parts 281 are provided on the outer wall of the sliding rod 28 above and below the middle shaft 24. The outer wall of the connecting parts 281 is connected by a shaft. The rotating sleeve 29 is rotatably connected. Under normal conditions, the connecting part 281 is located between the upper shaft 23 and the middle shaft 24 and between the middle shaft 24 and the lower shaft 25. A pull rod 30 is fixed to the side of the rotating sleeve 29. The pull rod 30 located below the middle shaft 24 extends horizontally towards the left partition 3, and the pull rod 30 located above the middle shaft 24 extends horizontally towards the right partition 4. A sliding sleeve 31 is fixed to the end of the pull rod 30 away from the rotating sleeve 29. A vertically extending limiting rod 32 is slidably connected to the inner wall of the sliding sleeve 31. The limiting rod 32 is fixed to the treatment tank 1, thereby enabling the middle shaft 24 and the stirring blade 27 to rotate with the upper shaft 23 via the sliding rod 28, while the middle shaft 24 and the stirring blade 27 can move vertically with the sliding rod 28.

[0024] In this invention, a second magnetic block 33 is installed on the outer wall of the sliding sleeve 31 away from the pull rod 30. The upper door panels 14 of the left partition door 3 and the right partition door 4 are both located close to the stirring unit 10. An electromagnetic block 34 is installed below the upper door panel 14 of the left partition door 3, and an electromagnetic block 35 is installed above the upper door panel 14 of the right partition door 4. When the electromagnetic blocks 34 and 35 are energized, they are magnetically attracted to the corresponding magnetic blocks 33. Under normal conditions, when both the left partition door 3 and the right partition door 4 are in a blocked state, the electromagnetic block 34 is located above the corresponding magnetic block 33, and the electromagnetic block 35 and the corresponding magnetic block 33 are in the same horizontal direction. When the upper door panel 14 of the left partition door 3 moves downward to open the top connecting area of ​​the first pool cavity 101 and the second pool cavity 102, the electromagnetic block 34 is energized and moves downward to gradually approach the magnetic block 33. Block 23, under magnetic attraction, causes the corresponding magnetic block 23, along with the slide rod 28, central shaft 24, and stirring blade 27, to move upward, thereby increasing the stirring area of ​​the stirring blade 27 and improving the agitation effect on the wastewater that has just entered the second chamber 102. When the upper door plate 14 of the right partition 4 moves downward to connect the second chamber 102 and the third chamber 103 for drainage, the electromagnetic block 35 is energized and, under magnetic attraction, moves the slide rod 28, central shaft 24, and stirring blade 27 downward, thereby ensuring the stability of the drainage from above and preventing the removal of too many impurities. Thus, by adjusting the movement of the stirring component 27 with the left partition 3 and the right partition 4 and the opening state of the corresponding upper door plate 14, the effectiveness of water intake and drainage treatment is ensured, further improving the treatment effect and efficiency of industrial water.
