[0035] like Figure 5-Figure 6As shown, the water discharge assembly 6 includes a second fixed seat 601, a second slider 602, a first baffle 603, a second guide rod 604, a third elastic member 605, a third fixed seat 606, a third slider 607, a pedal 608 and a first top plate 609. The second fixed seats 601 are welded to the lower parts of the left and right sides of the support frame 1, and the second sliders 602 are slidably arranged on the front sides of the two second fixed seats 601. A first baffle 603 is arranged between the two second sliders 602. A circular through hole is opened on the front side of the top of the first baffle 603. The backward movement of the first baffle 603 will make the filter box 2 be directly above the circular through hole on the front side of the top of the first baffle 603. The two second A second guide rod 604 is arranged between the front and rear sides of the fixed seat 601, and the two second guide rods 604 are slidably inserted into the adjacent second sliders 602. A third elastic member 605 is connected between the two second fixed seats 601 and the adjacent second sliders 602. A third fixed seat 606 is welded symmetrically on the front side of the bottom of the support frame 1, and a third slider 607 is slidably arranged on the upper rear side of the two third fixed seats 606. A pedal plate 608 is welded between the rear side walls of the two third sliders 607, and a first top plate 609 is symmetrically arranged on the rear side of the pedal plate 608. The downward sliding of the pedal plate 608 will drive the first top plate 609 to move downward and contact and cooperate with the second slider 602.

[0036] When it is necessary to filter the sewage on the construction site, the staff pours the sewage into the filter box 2, and the filter barrel 4 filters the sewage. The filtered sewage falls to the bottom of the filter box 2 through the evenly spaced circular holes in the lower part of the filter barrel 4. The first baffle 603 blocks the sewage in the filter box 2. The staff steps on the pedal 608 downward, and the pedal 608 drives the two third sliders 607 to slide downward between the rear sides of the third fixed seat 606. The pedal 608 slides downward and drives the two first top plates 609 to move downward. The two first top plates 609 move downward and drive the two second sliders 602 to slide backward in the second fixed seat 601, so that the third elastic member 605 is compressed. The two second sliders 602 slide backward and drive the first baffle 603 to move backward at the same time. The first baffle plate 603 moves, and the circular through hole on the front side of the top of the first baffle plate 603 is located directly below the filter box 2, so that the filtered sewage in the filter box 2 can be discharged. The filtered sewage is collected by the staff in a container placed directly below the filter box 2 through the circular through hole on the front side of the top of the first baffle plate 603. After the sewage is collected, the staff member's foot moves upward and disengages from the pedal plate 608, so that the two third elastic members 605 are reset and drive the two second sliders 602 to slide forward and reset on the second fixed seat 601. The two second sliders 602 slide forward and drive the two first top plates 609 to move forward and reset. The two first top plates 609 move forward to cause the pedal plate 608 to move upward. The pedal plate 608 moves upward and drives the two third sliders 607 on the adjacent third fixed seat The rear side of 606 slides upward to reset, and then the staff holds two adjacent first guide rods 509 and slides toward each other. The two first guide rods 509 slide toward each other and drive the adjacent top blocks 5010 to move toward each other, so that the two second elastic members 5011 are compressed. The two top blocks 5010 move toward each other and drive the two adjacent clamping plates 507 to rotate toward each other, so that the first elastic member 508 is compressed. Then the staff pulls the two handles 503 to move upward, and the two handles 503 move upward and drive the two L-shaped plates 502 to move upward. The two L-shaped plates 502 move upward and drive the filter barrel 4 to move upward and separate from the filter box 2. The filter barrel 4 moves upward and drives the two first sliders 3 to slide upward in the filter box 2. The two L-shaped plates 502 move upward. When the filter drum 4 is moved, the mounting rod 504, the fixing block 505, the first rotating shaft 506, the clamping plate 507 and the first elastic member 508 are driven upward, so that the staff can conveniently handle the larger residues remaining in the filter drum 4. When the mounting rod 504 is out of contact with the first fixing seat 501, the staff releases the first guide rod 509, so that the second elastic member 5011 is reset and drives the two adjacent first guide rods 509 to slide back to reset. After the larger residues in the filter drum 4 are processed, the staff pulls the two handles 503 to move downward. The downward movement of the two handles 503 drives the two L-shaped plates 502 and the filter drum 4 to move downward. The downward movement of the filter drum 4 drives the two first sliding blocks 3 to slide downward and reset in the filter box 2.When the two L-shaped plates 502 move downward, they drive the two mounting rods 504 to slide downward on the adjacent first fixed seats 501. The two mounting rods 504 slide downward to respectively cause the adjacent two card plates 507 to rotate toward each other, and the two first elastic members 508 are compressed. When the two mounting rods 504 slide downward, they cause the adjacent two top blocks 5010 to move backwards and reset. When the first rotating shaft 506 passes through the first fixed seat 501, the adjacent two card plates 507 begin to rotate backwards and reset under the action of the first elastic member 508. When the two card plates 507 are reset, they squeeze the two top blocks 5010 to move backwards and drive the two first guide rods 509 to slide backwards and reset. Finally, the two top blocks 5010 re-fix the card plates 507, and then the two second elastic members 5011 are compressed again. A layer of anti-skid pad is provided on the handle 503 to increase the friction between the staff's hand and the handle 503 to prevent slipping.

[0039] The staff rotates the first shift block 16 to rotate the third rotating shaft 15, and the rotation of the third rotating shaft 15 drives the two bevel gears 17 to mesh and rotate, and the meshing and rotation of the two bevel gears 17 drives the second rotating shaft 12 to rotate, and the rotation of the second rotating shaft 12 drives the storage block 13 to rotate. The staff connects the one-way valve 8 to the container pipeline filled with liquid polyaluminium chloride, and the liquid polyaluminium chloride enters the storage box 7 through the one-way valve 8 and falls to the second top plate 9. The fourth elastic member 10 drives the second top plate 9 to move upward, and the second top plate 9 moves upward to drive the liquid polyaluminium chloride to move downward into the delivery In the material pipe 11, the liquid polyaluminium chloride is stored in four semicircular grooves evenly spaced on the storage block 13. Due to the inclination angle of the feed pipe 11, the staff rotates the first shift block 16 to realize the rotation of the storage block 13, and at the same time, can drive the liquid polyaluminium chloride to move downward into the filter box 2 to contact and react with the sewage, which can achieve the effect of sewage purification. After the sewage purification is completed, the staff stops rotating the first shift block 16, and then the staff disconnects the one-way valve 8 from the container pipeline containing liquid polyaluminium chloride to stop conveying the liquid polyaluminium chloride.

[0041] When the staff rotates the first shift block 16 to allow the liquid polyaluminium chloride to enter the filter box 2 to react with the sewage, the staff starts the first servo motor 21, and the staff controls the output shaft of the first servo motor 21 to rotate. The rotation of the output shaft of the first servo motor 21 drives the fourth shaft 22 to rotate, and the rotation of the fourth shaft 22 drives the mounting plate 23 to rotate. The rotation of the mounting plate 23 drives the stirring rod 24 to rotate to stir the sewage and the liquid polyaluminium chloride in the filter box 2, so that the sewage and the liquid polyaluminium chloride are fully mixed. The rotation of the fourth shaft 22 can also drive the second shift block 25 to rotate. After the sewage purification is completed, the staff can turn off the first servo motor 21.

[0044] like Fig.12 As shown, it also includes a second protective cover 31, a second fixing ring 32, a second servo motor 33, a fifth rotating shaft 34 and a vortex plate 35. The second protective cover 31 is arranged outside the filter drum 4, and the second fixing ring 32 is arranged inside the second protective cover 31. The second servo motor 33 is arranged on the inner ring of the two second fixing rings 32. The second servo motor 33 can provide a power source. The top end of the output shaft of the second servo motor 33 is arranged with a fifth rotating shaft 34 through a coupling. The top end of the fifth rotating shaft 34 is arranged with a vortex plate 35. The vortex plate 35 is inside the filter drum 4.

[0045] The staff starts the second servo motor 33, and controls the output shaft of the second servo motor 33 to rotate. The rotation of the output shaft of the second servo motor 33 drives the fifth shaft 34 to rotate, and the rotation of the fifth shaft 34 drives the vortex plate 35 to rotate. Then the staff pours the sewage into the filter box 2 for filtration. The vortex generated when the vortex plate 35 rotates can accelerate the filtration of the sewage by the filter barrel 4. When the vortex plate 35 rotates, it can also make the residue remaining in the evenly spaced circular holes in the lower part of the filter barrel 4 float out, which is convenient for the staff to deal with the residue after purification. After completing the sewage filtration, the staff turns off the second servo motor 33, and the second protective cover 31 can protect the second servo motor 33.
