[0034] The process of collecting impurities in this device is as follows: the sewage is discharged into the sewage tank 3 through the water inlet pipe 2. Under normal circumstances, the top filter box 12 is located below the first button valve 4, and the filter box 12 on the second layer and below is located below the second button valve 19. At this time, the multiple arc platforms 20 can be rotated to the side of the first button valve 4 and the second button valve 19, and the buttons on the first button valve 4 and the second button valve 19 can be pressed, so that the first button valve 4 and the second button valve 19 can be opened, so that the sewage in the sewage tank 3 can be discharged into the top filter box 12 through the first button valve 4, and after being filtered through the filter net 13 in the top filter box 12, larger impurities can fall on the filter net 13, and the sewage can be discharged to the top filter box 12. The water falls into the annular guide box 17 below it, and the sewage in the annular guide box 17 can fall into the filter box 12 below it through the second button valve 19 below it, and after being filtered by the filter screen 13 in the filter box 12, the impurities are intercepted and the sewage falls into the annular guide box 17 below. Similarly, the sewage in the lowest filter box 12 can fall into the annular drainage box 22 and then be discharged through the drainage pipe 23. When the impurities on the filter screen 13 reach a certain level, the rotating motor 5 is started to rotate, and the rotating motor 5 can drive the uppermost rotating shaft 6 to rotate. The multiple rotating shafts 6 are connected by the transmission frame 7, so that all the rotating shafts 6 can rotate. When the rotating shaft 6 rotates, it can drive the fixed block 9 and the rotating rod 11 , the filter box 12 rotates, and then the filter box 12 below the first button valve 4 and the second button valve 19 can be replaced. After the filter box 12 rotates away, the arc platform 20 can be moved to the side of the first button valve 4 and the second button valve 19, and then the first button valve 4 and the second button valve 19 can be automatically closed to prevent sewage from being discharged. When the next filter box 12 rotates to below the first button valve 4 and the second button valve 19, the arc platform 20 can press the buttons on the first button valve 4 and the second button valve 19 again, and the first button valve 4 and the second button valve 19 can be opened to continue to discharge sewage and leave the filter box 1 below the first button valve 4 and the second button valve 19. 2 starts to control water, which can reduce the moisture contained in the impurities, and make the water fall into the annular guide box 17 and be discharged. When the rotating motor 5 drives the rotating shaft 6 to rotate again, the first gear 14 can be rotated to the bottom of the arc-shaped rack 15 and mesh with it, and then when the rotating shaft 6 rotates, the first gear 14, the rotating rod 11, and the filter box 12 can be rotated, and then the filter box 12 can be turned over, and the filter box 12 can be opened downward. In this process, the rotating rod 11 can drive the second bevel gear 33 to rotate, and the second bevel gear 33 is meshed with the first bevel gear 32, so that the first bevel gear 32 and the transmission shaft 29 can be rotated, and the transmission shaft 29 can drive the second sprocket 30 to rotate. The second sprocket 30 and the first sprocket 27 are connected by a transmission chain 31.Then, the first sprocket 27 and the transmission rod 25 can be rotated, and the transmission rod 25 can drive the cleaning plate 26 to rotate, and then the upper and lower surfaces of the filter screen 13 can be cleaned through the cleaning plate 26, and under the action of gravity, impurities can fall into the collection area 44. When the transmission rod 25 rotates, the eccentric wheel 34 can be driven to rotate. When the end of the eccentric wheel 34 farther from the transmission rod 25 rotates to the side of the pushing plate 35, the pushing plate 35, the pushing rod 36, the moving plate 39, and the knocking rod 40 can be pushed, and the telescopic spring 41 can be stretched. At this time, the knocking rod 40 is at a distance from the filter box 12. When the end of the eccentric wheel 34 closer to the transmission rod 25 rotates to the side of the pushing plate 35, Under the pulling force of the telescopic spring 41, the push plate 35, the push rod 36, the moving plate 39, and the knocking rod 40 can be pulled back to their original positions, and the knocking rod 40 can knock the filter box 12, which can make the filter box 12 vibrate and make impurities fall. The circular hole 38 and the push rod 36 can ensure the moving direction of the push rod 36, so that the impurities can fall into the collection area 44 for collection, and the sewage can fall into the filter area 43 and flow and filter. When the rotating motor 5 drives the rotating shaft 6 to rotate again, the filter box 12 can follow the movement. Through the meshing of the first gear 14 and the arc rack 15, the filter box 12 can be turned over again, and the opening is upward, which is convenient for filtering sewage.

[0035] Refer to the instruction manual Figure 1 And the instruction manual Figure 5 The transmission frame 7 includes a fifth rolling bearing 45 located at one side of the annular material guide box 17, the fifth rolling bearing 45 is installed on the annular material guide box 17 through a support shaft 46, a transmission column 47 is installed in the fifth rolling bearing 45, a second gear 48 is installed on the upper end of the transmission column 47, a third gear 49 is meshed with one side of the second gear 48, and the third gear 49 is installed at the lower end of the rotating shaft 6 on one side of the upper end of the annular material guide box 17, a fourth gear 50 is installed at the lower end of the transmission column 47, a fifth gear 51 is meshed with one side of the fourth gear 50, and the fifth gear 51 is installed at the upper end of the rotating shaft 6 on one side of the lower end of the annular material guide box 17;

[0036] The process of the transmission frame 7 connecting the rotating shaft 6 for transmission is as follows: when the upper rotating shaft 6 rotates, the third gear 49 at the lower end of the rotating shaft 6 can be driven to rotate, and the third gear 49 is engaged with the second gear 48, which can make the second gear 48, the transmission column 47, and the fourth gear 50 rotate, and the fourth gear 50 is engaged with the fifth gear 51, which can drive the fifth gear 51 and the rotating shaft 6 of the second layer to rotate, and so on, so that all the rotating shafts 6 can be rotated.

[0037] Refer to the instruction manual Fig.10The fourth gear 50 is provided with teeth at only one-fourth of the position, so that when the upper rotating shaft 6 rotates one circle, the lower rotating shaft 6 only rotates one-fourth of a circle, so that after the upper filter box 12 is replaced four times, the lower filter box 12 is only replaced once. Since the impurity content in the sewage is relatively high at the beginning, the impurity content is relatively low after filtration. Therefore, the lower filter box 12 can be cleaned after there are sufficient impurities in it, which can reduce the number of times the filter box 12 is cleaned, making it more convenient to use.

[0038] Refer to the instruction manual Figure 1 And the instruction manual Figure 2 A scraping plate 52 is provided in the filter box 12, and the scraping plate 52 is installed on the upper end of the cleaning plate 26 in the filter box 12. When the transmission rod 25 drives the cleaning plate 26 on the inner side of the filter screen 13 to rotate, the scraping plate 52 can be driven to rotate, so that the scraping plate 52 can clean the inner wall of the filter box 12.

[0039] Refer to the instruction manual Figure 1 , Instruction Manual Figure 3 , Instruction Manual Figure 8 And the instruction manual Fig. 9 A guide plate 53 is installed at one end of the filter box 12, and two guide blocks 54 installed on the treatment box 1 are provided on the outer side of the rotating shaft 6. A guide groove 55 is opened on the guide block 54, and one end of the guide plate 53 can extend into the guide groove 55. One end of the guide groove 55 is conical. Under normal circumstances, the side of the filter box 12 with the filter screen 13 is heavier and it will fall below, but the filter box 12 will tilt. When the filter box 12 rotates to the side of the guide block 54, the guide plate 53 can be guided by the cone at one end of the guide groove 55, so that when the filter box 12 rotates to the bottom of the first button valve 4 and the second button valve 19, it can be in a horizontal state, which is convenient for collecting sewage, and the arc platform 20 can also open the first button valve 4 and the second button valve 19.

[0040] Refer to the instruction manual Figure 1 , Instruction Manual Figure 4 , Instruction Manual Figure 6 , Instruction Manual Figure 7 And the instruction manual Figure 8 A fan-shaped receiving plate 56 is installed at the lower end of the collecting area 44, and a square collecting port 57 is opened on the fan-shaped receiving plate 56. Two cleaning racks 58 are installed on the fan-shaped receiving plate 56. A collecting box 59 is placed at the lower end of the collecting area 44. An inlet and outlet 60 opened on the processing box 1 is provided on one side of the collecting box 59. One end of the collecting box 59 passes through the inlet and outlet 60 and extends to the outside of the processing box 1;

[0041] When impurities fall into the collection area 44, the impurities can fall onto the fan-shaped receiving plate 56. The impurities on the fan-shaped receiving plate 56 can be pushed to the square collecting port 57 through the cleaning rack 58, and the impurities can pass through the square collecting port 57 and fall into the collection box 59 for collection. After the collection box 59 collects a certain amount of impurities, the collection box 59 can be taken out through the inlet and outlet 60, and the impurities can be cleaned.

[0042] Refer to the instruction manual Figure 1 , Instruction Manual Figure 4 , Instruction Manual Figure 6 , Instruction Manual Figure 7 And the instruction manual Figure 8 The cleaning rack 58 includes a push plate 61 located on one side above the fan-shaped holding plate 56, an L-shaped connecting rod 62 is installed on one side of the upper end of the push plate 61, a sixth rolling bearing 63 is installed on one end of the L-shaped connecting rod 62, and the sixth rolling bearing 63 is installed on the lower end of the rotating shaft 6, and a toggle rod 64 is installed on one end of the L-shaped connecting rod 62, and a side of the toggle rod 64 is provided with an avoidance opening 65 opened on the processing box 1, and one end of the toggle rod 64 passes through the avoidance opening 65 and extends to the outside of the processing box 1;

[0043] The process of cleaning impurities with the cleaning rack 58 is as follows: when it is necessary to clean the impurities on the fan-shaped receiving plate 56, the staff grabs the toggle rod 64 and drives the toggle rod 64 to move. The toggle rod 64 can drive the L-shaped connecting rod 62 and the push plate 61 to move, and make the sixth rolling bearing 63 rotate on the outside of the rotating shaft 6, and will not make the rotating shaft 6 rotate, and then the impurities can be pushed to the square collecting port 57 through the push plate 61, and the impurities fall into the collection box 59.
