[0029] The distance from one end of the sliding groove 112 close to the center of the sieve plate 15 to the center of the sieve plate 15 is different. This facilitates the stop blocks 115 in the sliding grooves 112 at different positions to push the sundries at different positions on the inner wall of the arc-shaped rod 52. During the rotation of the arc-shaped rod 52, the stop blocks 115 at each position work alternately, pushing the sundries on the inner arc surface of the arc-shaped rod 52 to the upper end of the connecting disk 53, so as to facilitate subsequent cleaning.

[0030] The elastic force of the spring 117 is greater than the elastic force of the elastic component inside the elastic telescopic rod 113.

[0031] The cylinder body 3 includes a filter barrel 31. The upper end of the filter barrel 31 is fixedly connected to the lower end of the motor bracket 18 through a connecting rod 32. Threads are provided on both the inner and outer circumferential surfaces of the filter barrel 31, and the pitch of the threads on the inner circumferential surface of the filter barrel 31 is smaller than the pitch of the threads on the outer circumferential surface of the filter barrel 31.

[0035] The diameter of the circular hole at the center of the connecting cylinder I 44 is greater than the length of the diagonal of the rectangular rod 51. When the rectangular rod 51 rotates, it will not drive the connecting cylinder I 44 to rotate.

[0036] A method for using an acidic wastewater treatment device, the method comprising the following steps:

[0037] Step 1: Pour the wastewater into the cylinder of the housing 14. At this time, the sieve holes on the filter barrel 31 are all above the partition plate 2 and the threaded disk 41 to prevent the wastewater from flowing into the lower end of the sieve plate 15.

[0038] Step 2: Add a flocculant and let it stand for a period of time.

[0039] Step 3: Start the motor I 19 and the motor II 118. The motor II 118 drives the partition plate 2 to move upward, the motor I 19 drives the arc-shaped rod 52 to rotate to clean the upper end of the sieve plate 15 to prevent blockage, and the motor I 19 also drives the waste treatment device 4 to move upward to facilitate the cleaning of waste.

[0040] Step 4: The filter cartridge 13 on the bottom plate 12 is loaded with alkaline substances for neutralizing acidic wastewater. After the reaction is completed, rotate the bottom plate 12 downward and thread the filter cartridge 13 onto the discharge port to filter the wastewater again.

[0041] The working principle of the present invention is as follows: When using this device, pour the wastewater into the cylinder of the outer shell 14 from the upper end. At this time, the sieve holes on the filter barrel 31 are all above the partition plate 2 and the threaded plate 41, so that the wastewater stays at the upper ends of the threaded plate 41 and the partition plate 2; add a flocculant and let it stand for a period of time;

[0042] Start motors Ⅰ19 and Ⅱ118. Motor Ⅱ118 drives gear 119 to rotate actively, and then drives transmission cylinder 120 to rotate. Transmission cylinder 120 drives connecting rod 121 and partition plate 2 to rotate. Partition plate 2 is threadedly connected to filter barrel 31, and then drives partition plate 2 to move upward. Motor Ⅰ19 drives rectangular rod 51 to rotate. Rectangular rod 51 is slidably engaged with the rectangular hole on connecting block 42, and then drives connecting block 42 to rotate. Connecting block 42 drives threaded disk 41 and connecting cylinder Ⅰ44 to rotate. Threaded disk 41 is engaged with the internal thread of filter barrel 31, and then moves upward during the rotation of threaded disk 41. Since the pitch of the external thread of filter barrel 31 is greater than that of the internal thread, and the rotation speeds of motors Ⅰ19 and Ⅱ118 are the same, the distance that partition plate 2 moves upward per unit time is greater than the distance that waste treatment device 4 moves upward, forming a height difference between the lower end face of partition plate 2 and the upper end face of threaded disk 41. The treated wastewater flows into the upper end of sieve plate 15 through the sieve holes on filter barrel 31 between the two height differences and passes through perforations 111 into the conical barrel of housing 14, leaving the precipitated waste on the upper ends of partition plate 2, threaded disk 41, and sieve plate 15. While motor Ⅰ19 drives rectangular rod 51 to rotate, rectangular rod 51 also drives connecting disk 53 to rotate. Connecting disk 53 drives arc rod 52 to rotate. The lower end face of arc rod 52 contacts the upper end face of sieve plate 15, pushing the sundries retained on the upper end face of sieve plate 15 to move. There are multiple stoppers 115 on sieve plate 15. When the inner arc surface of arc rod 52 contacts stopper 115, since the elastic force of spring 117 is greater than the elastic force of the elastic component in elastic telescopic rod 113, arc rod 52 pushes stopper 115 and slider 114 to move along the direction of chute 112, making stopper 115 slide on the inner arc surface of arc rod 52 and driving the sundries on the inner arc surface of arc rod 52 to move towards the center of connecting disk 53. When the elastic force received after elastic telescopic rod 113 is compressed is greater than that of spring 117, arc rod 52 pushes the spherical surface at the upper end of stopper 115 to move downward, compressing spring 117 until arc rod 52 passes over this stopper 115. Subsequently, under the elastic forces of elastic telescopic rod 113 and spring 117, stopper 115 moves back to its original position. Since the distances of multiple chutes 112 from the center of sieve plate 115 are different, when arc rod 52 rotates 360°, the sundries at the far end of arc rod 52 are pushed to the end close to connecting disk 53 by stoppers 115 in chutes 112 at different positions and move to the upper end of carrier plate 43 located in annular groove 54, cleaning the upper end of sieve plate 15 to avoid blockage. When motor Ⅰ19 starts to rotate at the beginning, although threaded disk 41 rotates and moves upward, since connecting cylinder Ⅰ44 is slidably engaged with annular groove 46, when threaded disk 41 moves upward, carrier plate 43 will still stay inside annular groove 54 for a period of time to collect sundries. When the lengths of connecting cylinder Ⅰ44 and connecting cylinder Ⅱ45 are the longest, carrier plate 43 will move upward together with threaded disk 41.Continue to start Motor I 19 and Motor II 118 until the partition plate 2, the threaded disc 41, and the carrier plate 43 all move to the upper end of the housing 1, then turn off Motor I 19 and Motor II 118. At this time, the partition plate 2, the threaded disc 41, and the carrier plate 43 drive the sundries to the upper end of the housing 1, facilitating the cleaning of the sundries. The partition plate 2 contacts the inner wall of the housing 1 and, while moving upward, also pushes the sundries adsorbed on the inner wall of the housing 1 to the upper part of the housing 1, saving cleaning time and improving the efficiency of wastewater treatment;

[0043] After the sundries are processed, reverse-start Motor I 19 and Motor II 118 to move the partition plate 2, the threaded disc 41, and the carrier plate 43 to their original positions, facilitating the input of new wastewater for treatment;

[0044] The filter cartridge 13 on the bottom plate 12 is loaded with alkaline substances for neutralizing acidic wastewater. The wastewater flowing from the sieve plate 15 into the conical barrel on the liquid storage barrel 14 comes into contact with the alkaline substances and starts a neutralization reaction. After the reaction is completed, rotate the bottom plate 12 downward and keep the filter cartridge 13 still threadedly connected to the discharge port. The wastewater flows out from the filter holes on the filter cartridge 13 and blocks the sundries, filtering the wastewater again. At the same time, when the connecting disc 53 is driven to rotate by Motor I 19, the connecting disc 53 also drives the stirring rod 55 to rotate, stirring the wastewater in the conical barrel and accelerating the reaction speed;

[0045] After the wastewater in the conical barrel is discharged, rotate the bottom plate 12, take out the filter cartridge 13 and the bottom plate 12, clean the sundries in the filter cartridge 13, put in the alkaline substances again, and then screw them into the bottom of the conical barrel through threads for the next use.
