The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 4 As shown, the high-concentration wastewater treatment device of this utility model includes: a treatment tank 1; a first separation net 2, a second separation net 3, and a third separation net 4 respectively arranged from top to bottom on the treatment tank 1; a cleaning component 5 for cleaning the surfaces of the first separation net 2, the second separation net 3, and the third separation net 4; and a collection component 6 for collecting the cleaned waste.

[0024] It should be noted that the first separating mesh 2, the second separating mesh 3, and the third separating mesh 4 are all made of corrosion-resistant metal filter mesh, and the pore diameter of the first separating mesh 2 is larger than that of the second separating mesh 3, the pore diameter of the second separating mesh 3 is larger than that of the third separating mesh 4, and the first separating mesh 2, the second separating mesh 3, and the third separating mesh 4 are all arc-shaped structures.

[0025] The cleaning assembly 5 includes: three cleaning brushes 501, which are respectively located above the adjacent first separating net 2, second separating net 3, and third separating net 4; a lead screw 502 that drives the cleaning brushes 501 to move; the cleaning brushes 501 are designed in an arc shape to match the first separating net 2, second separating net 3, and third separating net 4, so that the swept dirt is brought closer to the center, thereby facilitating the sweeping of dirt through the through grooves 604 in the middle of both sides of the processing box 1 into the collection box 601; a motor 503 that drives the lead screw 502 to rotate, and the motor 503 is fixedly installed on the processing box 1; the motor 503 is preferably a servo motor, which can perform forward and reverse rotation; a gear 504 fixedly installed at one end of the lead screw 502, and two adjacent gears 504 mesh with each other; and a guide rod 505 that guides the movement of the cleaning brushes 501, with both ends of the guide rod 505 fixedly installed on the processing box 1.

[0026] When performing multiple separation processes on contaminants in high-concentration wastewater, the motor 503 is started, and the output end of the motor 503 drives the adjacent lead screw 502 to rotate. This causes the motor 503 at one end of the lead screw 502 to mesh with the motor 503 at the end of the other adjacent lead screw 502. At this time, the three lead screws 502 rotate, driving the cleaning brushes 501 threaded on the lead screws 502 to move. This allows the corresponding cleaning brushes 501 on the first separation screen 2, the second separation screen 3, and the third separation screen 4 to sweep and brush the contaminants separated from the surface, preventing the filter holes from becoming clogged and affecting the separation efficiency of the wastewater contaminants.

[0027] It should be added that both ends of the lead screw 502 are equipped with sealed bearings, and the inner ring of the sealed bearing is fixedly connected to the surface of the lead screw 502, while the outer ring of the sealed bearing is fixedly connected to the interior of the processing box 1. By setting the sealed bearings, the stability of the rotation of the lead screw 502 is improved, and the sealing performance of the interior of the processing box 1 is also improved.

[0028] It should be added that three grooves are equally spaced on both sides of the inner wall of the processing box 1. The lead screw 502 and the guide rod 505 are both set in the adjacent grooves, and the bottom of the grooves is set as an inclined surface. By setting the lead screw 502 and the guide rod 505 in the grooves on the inner wall of the processing box 1, when the corresponding cleaning brush 501 cleans the filter holes on the surface of the first separation screen 2, the second separation screen 3 and the third separation screen 4, the cleaning brush 501 can sweep more thoroughly. In addition, the inclined surface at the bottom of the groove makes it easy for the filtered dirt to fall onto the separation screen, which is convenient for cleaning.

[0029] Considering the collection and treatment of waste from cleaning, the collection component 6 includes: a collection box 601 fixedly installed at both ends of the treatment box 1; three partitions 602 equidistantly arranged on the collection box 601, with the three partitions 602 corresponding to the adjacent first separation net 2, second separation net 3 and third separation net 4, and the side wall of the partition 602 fitting against the inner wall of the collection box 601, thus isolating waste of different sizes; a pull rod 603 fixedly installed between the three partitions 602; a through groove 604 opened at both ends of the treatment box 1, and the through groove 604 communicating with the corresponding collection box 601; and three filter screens 605 fixedly installed at equal intervals on the through groove 604.

[0030] It should be noted that the pore size of filter screen 605 is the same as the pore diameter of the third separation screen 4.

[0031] As the cleaning brush 501 reciprocates and sweeps the dirt on the corresponding first separation net 2, second separation net 3, and third separation net 4, the cleaning brush 501 sweeps the dirt through the channel 604 into the collection box 601. The corresponding dirt is collected by the partition 602 in the collection box 601, while the water in the dirt is filtered out through the filter screen 605. When processing the dirt in the collection box 601, the pull rod 603 can be pulled out of the collection box 601 to empty the dirt on the partition 602.

[0032] It should be noted that the bottom of the filter screen 605 is flush with the adjacent partition 602, and the top of the filter screen 605 is flush with the bottom of the corresponding first separation screen 2, second separation screen 3 and third separation screen 4. When the cleaning brushes 501 on the first separation screen 2, second separation screen 3 and third separation screen 4 sweep the dirt filtered on the separation screen to both sides, the dirt on the separation screen falls onto the corresponding partition 602 through the through groove 604 for collection, while the moisture in the dirt is filtered out through the filter screen 605.

[0033] Working principle: When the power is turned on, during the multiple separation treatment of pollutants in high-concentration wastewater, the motor 503 is started, and the output end of the motor 503 drives the adjacent lead screw 502 to rotate, so that the motor 503 at one end of the lead screw 502 meshes with the motor 503 at the end of the other adjacent lead screw 502. At this time, the three lead screws 502 rotate, driving the cleaning brushes 501 threaded on the lead screws 502 to move. The corresponding cleaning brushes 501 on the first separation screen 2, the second separation screen 3, and the third separation screen 4 sweep the pollutants separated from the surface to prevent the filter holes from clogging. When the cleaning brushes 501 reciprocate to sweep the pollutants on the corresponding first separation screen 2, the second separation screen 3, and the third separation screen 4, the cleaning brushes 501 sweep the pollutants through the through groove 604 into the collection box 601. The corresponding pollutants are collected by the partitions 602 in the collection box 601, while the water in the pollutants is filtered out through the filter screen 605.
