[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:

[0013] 1. By arranging electromagnets in four directions on the side wall of the sleeve roller, the present invention can specifically adsorb metal objects and be used in combination with the first filter screen for replacement. For example, when treating wastewater containing magnetic metals such as iron, cobalt, and nickel, these metals can be directly adsorbed on the box body, achieving preliminary separation of metals and improving the purity of metal recovery.

[0014] 2. Traditional wastewater treatment methods may precipitate metals together with other impurities or filter them out and treat them as waste, resulting in waste of metal resources. In this solution, the metal objects adsorbed are collected by suction through the recovery structure and then uniformly discharged for recycling, enabling the metals to be reused.

[0015] 3. In a common filtering device when treating metal-containing wastewater, metal particles tend to accumulate on the filter screen, leading to blockage of the filter screen over time. In this solution, the electromagnets arranged in four directions and the first filter screen reduce the accumulation of metal objects on the first filter screen while adsorbing metal objects and filtering, reducing the risk of blockage. For example, when treating machining wastewater containing a large amount of metal debris, the electromagnets can adsorb the metal debris when the wastewater passes through the filter screen, preventing it from blocking the pores of the filter screen, thus ensuring the continuous and effective progress of the filtering process.

[0016] 4. When cleaning the filter screen of existing filtering equipment, it may be necessary to disassemble the entire filtering device, which is complex and time-consuming. In this solution, through the cleaning structure, the first cleaning box and the second cleaning box are sleeved on the box body and the first filter screen. After the power is cut off and the demagnetization occurs, the adsorbed metal objects are dialed off by the rotation of the cleaning brush rollers, and the operation is relatively simple.

[0017] 5. The arrangement of electromagnets in four directions and the first filter screen facilitates the replacement and adjustment of the electromagnets or the filter screen during the operation of the equipment. Compared with traditional integrated filtering and adsorption equipment, if a local problem occurs with a certain electromagnet or the filter screen, this solution can be more conveniently adjusted locally. For example, when treating metal-containing wastewater with complex components, it may be necessary to adjust the magnetic field intensity of the electromagnets or replace filter screens 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

[0036] Working principle:

[0037] First, load the wastewater through the treatment tank 11 in the main body structure 1, and pipes can be set at both the left and right ends of the treatment tank 11 for water inlet and drainage;

[0038] Driven by the first electric slide rail 13 on the bracket 12, the first hydraulic cylinder 32, the cleaning structure 3, and the recycling structure 4 on the first pallet 31 move left and right, making the first hydraulic cylinder 32 correspond to the other end of one of the boom arms 14. At this time, both the cleaning structure 3 and the recycling structure 4 are located above the corresponding filtering structure 2; then, the first hydraulic cylinder 32 can be driven to extend, and the boom arm 14 is lifted by contacting the other end of the boom arm 14 through the first hydraulic cylinder 32. That is, the opposite boom arm 14 rises in the lifting groove, and the filtering component on the shaft rod 17 is driven to rise, prompting the box body 22 to separate from the lower wall inside the treatment tank 11;

[0039] Then, the first motor 16 inside the boom arm 14 can be driven, and the filtering structure 2 on the shaft rod 17 is driven to rotate through the bearing 15, that is, the sleeve roller 21 is driven to rotate, and the box body 22 on the side wall of the sleeve roller 21 and the first filter screen 24 are replaced; after replacement, the boom arm 14 is driven to descend and reset by the contraction of the first hydraulic cylinder 32, and the replaced box body 22 is vertically attached to the lower wall inside the treatment tank 11. Then, metal can be intercepted 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 side wall of the box body 22;

[0040] As the replaced box body 22 and the first filter screen 24 rotate 180 degrees and face the cleaning structure 3; at this time, the second hydraulic cylinder 33 can be driven to contract, and the cleaning component 35 is driven to descend through the second pallet 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 connecting rod 353 and the sliding seat 354, moving the other end of the second cleaning box 355 away from the first cleaning box 351. Then, as it descends, the first cleaning box 351 is sleeved on multiple box bodies 22 and the filter screen on one side of the sleeve roller 21, and after the second cleaning box 355 is reset and attached to the first cleaning box 351, the box body 22 and the first filter screen 24 are sleeved; at this time, the air extractor 44 and the second motor 356 in the recycling structure 4 can be driven;

[0041] The second motor 356 drives the cleaning brush roller 357 to rotate to brush off the metal objects on the first filter screen 24 and the box body 22 (the electromagnet 23 is powered off to demagnetize). Then, with the suction of the air extractor 44, the metal residues are adsorbed into the recycling box 42 supported by the box seat 41. Since the recycling box 42 is L-shaped, the metal objects flow from one end of the recycling box 42 to the other end, and the other end of the recycling box 42 is vertically downward. At the same time, the suction end of the air extractor 44 is blocked by the side baffle 5 and the second filter screen 45, and with the help of the arc-shaped wall surface on the upper wall of the baffle 43, the metal objects cannot pass through the second filter screen 45 due to gravity and moving speed and fall on the discharge plate 465 in the discharging component 46 for centralized collection;

[0042] The collected metal objects can drive the electric push rod 462 to contract. The electric push rod 462 will turn a certain distance within the support 461, and drive the turning arm 464 to turn within the turning frame 463, so as to drive the discharge plate 465 away from the lower wall of the recycling box 42, and the discharge plate 465 will tilt backward for unloading.

[0043] Since the filtering structures 2 are arranged at both the left and right ends in the treatment tank 11, when one of the filtering structures 2 is replaced, the other filtering structure 2 can still be in use, without causing the waste water to be left unprocessed.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
