[0012] The present invention proposes an industrial wastewater treatment equipment containing metal impurities, which has the following beneficial effects: the electromagnet and the first filter screen are arranged in four directions on the side wall of the sleeve roller through the filtering structure, so that the metal objects are adsorbed on the box body by the magnetic force generated by the electromagnet while the drainage is intercepted by the filter screen, and the arrangement in four directions is also convenient for replacement and adjustment, so as to prevent blockage caused by long-term use; secondly, the cleaning structure cooperates with the main structure to promote the first cleaning box and the second cleaning box to be installed on the box body and the first filter screen, and then the electromagnet is de-energized and demagnetized, and the metal objects adsorbed on the first filter screen and the box body are moved away by the rotation of the cleaning brush roller, and finally the metal objects are sucked and collected by the recovery structure, and then discharged uniformly by the discharge assembly, so as to realize the recycling of metal objects and the cleaning of the first filter screen; in summary, the present invention has the following effects: 1. The present invention can specifically adsorb metal objects by arranging electromagnets on four directions of the side wall of the sleeve roller, and can be replaced and used in conjunction with the first filter screen. For example, when treating wastewater containing magnetic metals such as iron, cobalt, and nickel, these metals can be directly adsorbed on the box body, thereby achieving preliminary separation of the metals and improving the purity of metal recovery.

[0013] 2. Traditional wastewater treatment methods may precipitate metals together with other impurities or treat them as waste after filtering, resulting in a waste of metal resources; this solution uses a recovery structure to extract and collect adsorbed metals, and then discharge and recycle them in a unified manner, so that the metals can be reused.

[0014] 3. When a conventional filter device treats metal-containing wastewater, metal particles tend to accumulate on the filter screen, which causes the filter screen to become clogged over time. In this solution, the electromagnets and the first filter screen arranged in four directions absorb and filter metal objects, while reducing the accumulation of metal objects on the first filter screen and the risk of clogging. For example, when treating machining wastewater containing a large amount of metal debris, the electromagnet can absorb the metal debris when the wastewater passes through the filter screen to prevent it from clogging the pores of the filter screen, thereby ensuring the continuous and effective filtration process.

[0015] 4. The existing filtering equipment may need to disassemble the entire filtering device when cleaning the filter, which is complicated and time-consuming. The present solution uses a cleaning structure to mount the first cleaning box and the second cleaning box on the box body and the first filter. After power failure and demagnetization, the cleaning brush roller is used to rotate to remove the adsorbed metal objects, which is relatively easy to operate.

[0016] 5. Electromagnets and the first filter are arranged in four directions. This layout facilitates the replacement and adjustment of the electromagnets or the filter during the operation of the equipment. Compared with the traditional integrated filtration and adsorption equipment, if a problem occurs locally in an electromagnet or the filter, this solution can make local adjustments more conveniently. For example, when treating metal-containing wastewater with complex components, it may be necessary to adjust the magnetic field strength of the electromagnet or replace filters of different specifications according to the content and properties of different metals. The structural design of this solution makes these operations easier to achieve. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Working principle: First, wastewater is loaded through the treatment pool 11 in the main structure 1, and pipes can be set at both ends of the treatment pool 11 for water inlet and water outlet; The first hydraulic cylinder 32, the cleaning structure 3 and the recovery structure 4 on the first support plate 31 are driven to move left and right through the first electric slide rail 13 on the bracket 12, and the first hydraulic cylinder 32 is aligned with the other end of one of the arm supports 14. At this time, the cleaning structure 3 and the recovery structure 4 are both located above the corresponding filtering structure 2; the first hydraulic cylinder 32 can be driven to extend, and the arm support 14 is lifted by the first hydraulic cylinder 32 contacting the other end of the arm support 14, that is, the relative arm support 14 is lifted in the lifting slot, and the filtering assembly on the shaft rod 17 is driven to lift, so that the box body 22 is separated from the lower wall of the treatment tank 11; Then, the first motor 16 in the arm 14 can be driven to rotate the filter structure 2 on the shaft 17 through the bearing 15, that is, the sleeve roller 21 can be driven to rotate, and the box body 22 and the first filter screen 24 on the side wall of the sleeve roller 21 can be adjusted to be replaced; after the replacement, the first hydraulic cylinder 32 is contracted to cause the arm 14 to descend and reset, and the replaced box body 22 is vertically attached to the lower wall of the treatment pool 11, so that the metal can be intercepted and filtered through the first filter screen 24, and at the same time, the electromagnet 23 is energized to generate a strong magnetic force to adsorb the metal on the outer wall of the box body 22; As the replaced box body 22 and the first filter screen 24 rotate 180 degrees and face the cleaning structure 3, the second hydraulic cylinder 33 can be driven to contract, and the cleaning assembly 35 can be driven to descend through the second support plate 34; at the same time, the second electric slide rail 352 is driven to drive the second cleaning box 355 to move to the right through the slide seat 354 with the help of the connecting rod 353, so that the second cleaning box 355 is away from the other end of the first cleaning box 351, and then the first cleaning box 351 is sleeved on the multiple box bodies 22 and the filter screen on one side of the sleeve roller 21 as it descends, and the second cleaning box 355 is reset and fits with the first cleaning box 351 to achieve the sleeved box body 22 and the first filter screen 24; at this time, the vacuum pump 44 and the second motor 356 in the recovery structure 4 can be driven; The cleaning brush roller 357 is driven by the second motor 356 to rotate and brush off the metal objects on the first filter screen 24 and the box body 22 (the electromagnet 23 is powered off and demagnetized), and then with the suction force of the vacuum pump 44, the metal residues are adsorbed into the recovery box 42 supported by the box seat 41.
