[0019] Wastewater enters the mixing chamber 2 through the first inlet hole 6, and precipitant enters the mixing chamber 2 through the second inlet hole 7. The stirring motor 3 drives the stirring shaft 4 to rotate, and the stirring protrusions 5 stir the wastewater and precipitant. At this time, the rotating device 16 drives the delivery device 15 to move above the filter chamber 18, and the delivery pump 23 draws the settled liquid into the delivery device 15. The delivery device 15 inputs the liquid into the filter tank 20 of the filter frame 19, and the liquid enters the filter chamber 18 after passing through the filter holes 21.

[0020] When the filter frame 19 needs to be replaced, the lifting device 9 moves the fixing plate 10 upward, and then the rotating device 16 rotates the rotating shaft 11, causing the gripping device 14 to rotate above the filter frame 19. Next, the lifting device 9 moves the gripping device 14 downward, gripping the filter frame 19. Then, the lifting device 9 moves the filter frame 19 upward out of the filter chamber 18. The rotating device 16 then moves the filter frame 19 to the side of the filter tank 17, making it very convenient to remove. At this point, the filter frame 19 can be replaced on the gripping device 14. Similarly, through the cooperation of the rotating device 16, the lifting device 9, and the gripping device 14, the clean filter frame 19 is placed back into the filter tank 17.

A vertical push rod 50 is fixed on the push rod of the electric push rod 49. A gripping slide groove 44 is provided for the vertical push rod 50 to be inserted.

[0024] When the filter frame 19 needs to be grasped, the rotating device 16 moves the grasping bar 33 above the filter tank 17. Then, the lifting device 9 drives the grasping device 14 to move downward, so that the vertical push rod 50 is inserted into one of the grasping sliding grooves 44. Then, the electric push rod 49 drives the grasping lower rod 40 to move away from the filter tank 17. At this time, the grasping spring 38 is in a compressed state. Then, the lifting device 9 continues to drive the grasping device 14 to move downward until the grasping positioning post 42 is aligned with the corresponding positioning hole 43. At this time, the electric push rod 49 drives the vertical push rod 50 to reset. During this process, the grasping spring 38 rebounds, driving the grasping positioning post 42 to be inserted into the positioning hole 43, thereby grasping the filter frame 19.

[0025] When one of the gripping sliders 36 moves, the gripping slider 36 drives the linkage sleeve 46 to move via the push rod 41. The linkage sleeve 46 drives another slider to move via another push rod 41, thereby controlling the other gripping positioning post 42 to move simultaneously.

[0026] The electric push rod 49 is set separately from the gripping device 14, so the gripping device 14 does not need to be electrically controlled and will not affect the rotation of the gripping device 14.

[0027] like Figure 5 As shown, the support ring 22 is provided with a limiting hole 51, and a limiting protrusion 52 that is inserted into the limiting hole 51 is fixed on the upper side of the filter tank 17.

[0029] The rotating motor 53 drives the drive pulley 54 to rotate, and the drive pulley 54 drives the driven pulley 55 to rotate through the connecting belt 56, thereby driving the rotating shaft 11 to rotate.

[0030] like Figure 4As shown, the outer wall of the insertion tube 32 is provided with an annular groove 57, and a sealing ring 58 is installed in the annular groove 57. The outer wall of the sealing ring 58 abuts against the inner wall of the first channel 29. The sealing ring 58 can increase the sealing performance between the insertion tube 32 and the inner wall of the first channel 29.

[0031] A third rotating rod 59 can also be fixed on the rotating shaft 11, and a gripping device 14 is also installed on the third rotating rod 59. This allows the filter frame 19 to be replaced to be placed on the gripping device 14 in advance, and can be rotated directly when replacement is needed, saving replacement time. Below the gripping device 14, there is also an electric push rod 49 fixed by a bracket 60. A vertical push rod 50 is also fixed on the electric push rod 49 to control the gripping device 14, and can also control the gripping device 14 that rotates from the first rotating rod 12.
