[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a wire-cut iron powder and iron mud separation circulation filter, including a filter tank 1, a top cover 2 is arranged on the top of the filter tank 1, a motor 5 is fixedly connected to the top of the top cover 2, a main shaft 6 is fixedly connected to the output end of the motor 5, a liquid inlet pipe 3 is fixedly connected to the inside of the filter tank 1, a liquid outlet pipe 4 is fixedly connected to the inside of the top cover 2, a cross support frame 7 is arranged at the bottom of the main shaft 6, a card slot 10 is opened inside the main shaft 6, a connecting pin 11 is fixedly connected to the top of the cross support frame 7, a limiting component is arranged inside the connecting pin 11, a limiting ring 13 is arranged inside the connecting pin 11, and a limiting ring 13 is arranged inside the limiting ring 1 The outer wall of the limit assembly is connected to a connecting rod 14, one end of the connecting rod 14 is rotatably connected to a block 15, the outer wall of the block 15 is embedded in the card slot 10, the outer wall of the connecting pin 11 is slidably connected to the inside of the main shaft 6, the outer wall of the limit assembly is sleeved with a first spring 16, one end of the first spring 16 is fixedly connected to the inside of the connecting pin 11, and the other end of the first spring 16 is fixedly connected to one end of the limit ring 13, the bottom of the cross support frame 7 is fixedly connected to a magnet bar 8, the limit assembly includes a connecting column 12, both ends of the connecting column 12 are fixedly connected to the inside of the connecting pin 11, and the outer wall of the limit ring 13 is slidably connected to the outer wall of the connecting column 12;

[0031] Specifically, in the wastewater treatment system, the liquid inlet pipe 3 is a crucial component. This pipe is responsible for introducing wastewater from the outside into the interior of the filter tank 1. The filter tank 1 is the first step in wastewater treatment. Its internal design is ingenious and can effectively remove impurities and harmful substances in the wastewater. The wastewater enters the bottom of the filter tank 1 through the liquid inlet pipe 3, which ensures that the wastewater is evenly distributed in the tank and is ready for subsequent treatment steps. The motor 5 is the power source of the entire treatment system, and its output end is closely connected to the main shaft 6. When the motor 5 is started, the main shaft 6 will rotate accordingly, thereby driving the magnet bar 8 at the bottom of the cross support frame 7 to rotate. The magnet bar 8 is designed to absorb iron powder in the wastewater. By rotating, the magnet bar 8 can more efficiently contact the iron powder in the wastewater, thereby achieving rapid and effective adsorption and collection. Over time, the iron powder on the magnet bar 8 will gradually increase, and it needs to be cleaned at this time. In order to facilitate cleaning, the system has designed a unique disassembly method. First, it is necessary to open the top cover 2 of the filter tank 1 so that the cross support frame 7 can be exposed. Subsequently, the magnet bar 8 can be taken out of the filter tank 1 by pulling out the cross support frame 7. This design is not only simple and practical, but also can ensure that the magnet bar 8 or the filter tank 1 will not be damaged during the disassembly process. The connection between the cross support frame 7 and the filter tank 1 is achieved by the connecting pin 11. The connecting pin 11 not only plays a connecting role, but also realizes the locking of the cross support frame 7 through the internal block 15 and the card slot 10 structure. The block 15 is connected to the limit ring 13 through the connecting rod 14 and is limited on the outer wall of the connecting column 12. In this way, the block 15 can only move within a specific range, thereby ensuring the stability and reliability of the connection. At the same time, the limit ring 13 is also supported by the tension of the first spring 16. The tension of the first spring 16 can not only provide a stable supporting force for the limit ring 13, but also push the block 15 to be embedded in the card slot 10, thereby further enhancing the firmness of the connection. This design makes it difficult for the block 15 to slide out of the card slot 10 when disassembling or installing the cross support frame 7, thereby ensuring the convenience and safety of operation. After the magnet bar 8 is taken out of the filter tank 1, the iron powder on it can be cleaned. The cleaned magnet bar 8 can be installed on the cross support frame 7 again and put back into the filter tank 1 for the next wastewater treatment. Through such a design, the wastewater treatment system not only achieves the effective removal of iron powder in the wastewater, but also ensures the maintainability and sustainability of the system.

[0032] Reference Figure 2 and Figure 4, a conical cover 18 is fixedly connected to the outer wall of the main shaft 6, a stirring plate 22 is fixedly connected to the outer wall of the main shaft 6, a through hole 17 is opened inside the stirring plate 22, and a plurality of through holes 17 are arranged in a rectangular array, a limit plate 19 is slidably connected inside the cross support frame 7, a scraper 9 is fixedly connected to the bottom of the limit plate 19, a telescopic rod 20 is arranged inside the cross support frame 7, one end of the telescopic rod 20 is fixedly connected to the top of the limit plate 19, and the other end of the telescopic rod 20 is fixedly connected to the inside of the cross support frame 7, a second spring 21 is sleeved on the outer wall of the telescopic rod 20, one end of the second spring 21 is fixedly connected to the top of the limit plate 19, and the other end of the second spring 21 is fixedly connected to the inside of the cross support frame 7, and the bottom of the scraper 9 is attached to the inner wall of the filter tank 1;

[0033] Specifically, in the integrated process of iron powder collection and wastewater treatment, the cross support frame 7 plays a vital role. It is firmly installed in the center of the entire device, carrying important components such as the scraper 9, ensuring the smooth progress of the entire process. The scraper 9 is the core component of iron powder collection. Through the ingenious design of the second spring 21, the scraper 9 can fit tightly on the bottom of the filter tank 1. When the iron powder precipitated in the filter tank 1 accumulates to a certain extent, the scraper 9 can easily scrape off the iron powder attached to the bottom under the tension of the second spring 21, so as to achieve efficient collection of iron powder. At the same time, the introduction of the conical cover 18 not only optimizes the structure of the device, but also plays a significant role in preventing the iron powder from floating. Its unique conical design makes it difficult for the iron powder adsorbed on the inner wall of the conical cover 18 to escape, thereby effectively reducing the loss caused by the floating of the iron powder. In addition, the conical cover 18 can also guide the flow of wastewater, ensuring that the wastewater can flow evenly through the filter tank 1, thereby improving the efficiency of wastewater treatment. In order to further improve the effect of wastewater treatment, the stirring plate 22 is cleverly designed inside the device. It contacts the wastewater through a plurality of through holes 17, and fully stirs the wastewater by rotating or vibrating the stirring plate 22. This stirring action can not only prevent the iron powder from sinking to the bottom of the wastewater, but also increase the contact area between the wastewater and the filter material, thereby improving the treatment effect of the wastewater. In the final stage of the entire process, the treated wastewater is discharged through the liquid outlet pipe 4. The design of the liquid outlet pipe 4 takes into account the control of the wastewater flow rate and the convenience of discharge, ensuring that the wastewater can flow out of the device smoothly, while avoiding leakage and contamination of the wastewater during the discharge process.

[0034] Working principle: When the wire is used to cut the iron powder and iron mud separation circulation filter, first the wastewater enters the filter tank 1 from the bottom of the filter tank 1 through the liquid inlet pipe 3, and then the output end of the motor 5 drives the main shaft 6 to rotate, thereby driving the magnet bar 8 at the bottom of the cross support frame 7 to rotate to adsorb and collect the iron powder in the wastewater. When the magnet bar 8 needs to be disassembled, the top cover 2 is opened and the cross support frame 7 is pulled out. The cross support frame 7 slides into the cross support frame 7 through the connecting pin 11 for connection, and the block 15 in the connecting pin 11 is embedded in the card slot 10 for locking. The block 15 is connected to the limit ring 13 through the connecting rod 14 and is connected to the outer wall of the connecting column 12. The limiting ring 13 is supported by the tension of the first spring 16, so that the tension of the first spring 16 pushes the card block 15 to be embedded in the card slot 10 and is not easy to slide out. Then the iron powder on the magnet bar 8 can be cleaned. In the process of collecting the iron powder, the scraper 9 in the cross support frame 7 is supported by the tension of the second spring 21, so that the scraper 9 fits the bottom of the filter tank 1 to scrape off the iron powder precipitated in the filter tank 1. At the same time, the conical cover 18 can reduce the floating of iron powder that violates the adsorption. The stirring plate 22 can stir the wastewater through the multiple through holes 17 opened inside to prevent the iron powder from sinking to the bottom. Then the treated wastewater is discharged through the liquid outlet pipe 4.
