A central shaft 21 is rotatably arranged inside the inner tube 14, and spiral blades 22 are fixed on the outer periphery of the central shaft 21, and the outer edge of the spiral blades 22 abuts against the inner wall of the inner tube 14.

[0025] Reference Figure 2 , reference Figure 4A fixing frame 20 is arranged on the upper side of the storage barrel 11, and the fixing frame 20 is fixed to the upper end surface of the box body 10 through a supporting rod. The upper end of the central axis 21 passes through the fixing frame 20 and is rotatably connected in the fixing frame 20.

The magnetic clamping block 50 has magnetism. After the electromagnet 51 is energized, the magnetism of the electromagnet 51 is opposite to that of the magnetic clamping block 50.

[0026] Reference Fig. 9 , as shown in the box body 10 , the inner cavity of the mixing disk 13 is fixed with arc-shaped partitions 132 distributed circumferentially around the axis of the mixing disk 13 , and a gap is formed between two adjacent arc-shaped partitions 132 , and a plurality of gaps are respectively connected to a plurality of drainage ports 131 .

[0027] Reference Figure 8 The lower end surface of the box body 10 is fixed with two upper movable seats 102 which are respectively slidably connected to the two upper guide rails 30. The lower side surface of the upper guide rail 30 is fixed with a reinforcing rib 301 arranged along its length direction. A second motor 31 is fixed on the side surface of the upper movable seat 102. A roller 32 abutting against the reinforcing rib 301 is fixed on the output shaft of the second motor 31. The roller 32 is made of rubber material, and the friction between the roller 32 and the reinforcing rib 301 is large.

[0028] Reference Figure 5 A lower moving seat 41 is slidably connected to the box body 10, and both ends of the upper guide rail 30 are respectively fixed on the two lower moving seats 41, and two support wheels 43 abutting against the upper end surface of the lower guide rail 40 are rotatably connected in the lower moving seat 41. Two third motors 42 are fixed on the side of the lower moving seat 41, and the two support wheels 43 in each lower moving seat 41 are respectively fixed on the output shafts of the two third motors 42 on the corresponding sides. The tangential direction of the rotation of the support wheel 43 at the abutment between the upper end surface of the lower guide rail 40 is parallel to the length direction of the lower guide rail 40, and both ends of the support wheel 43 extend outward along its radial direction to form an annular protrusion, so that the support wheel 43 is stuck on the upper end surface of the lower guide rail 40.

[0029] When the present invention is in use, the box body 10 is located at the end of the upper guide rail 30, and the lower movable seat 41 is located at the end of the lower guide rail 40, so that the box body 10 is located at the corner of the sewage treatment tank, thereby facilitating operators to add powdered sewage treatment additives into the storage barrel 11.

[0030] After the powdered sewage treatment additive is added into the storage barrel 11, the spiral blades 22 and the inner tube 14 remain stationary at this time, so that the spiral blades 22 block the lower end of the storage barrel 11, thereby retaining the additive in the storage barrel 11, the mixing disk 13 is immersed in the sewage, and the water inlet 121 is located below the sewage surface.

[0031] At this time, the third motor 42 is started to drive the support wheel 43 to rotate, so that the lower moving seat 41 slides along the lower guide rail 40, thereby driving the box body 10 and the upper guide rail 30 to move along the lower guide rail 40, thereby driving the mixing plate 13 to move along the lower guide rail 40. At the same time, the first motor 60 is started to drive the driving gear 61 to rotate, thereby rotating the driven gear 62, thereby driving the storage barrel 11 to rotate, and then rotating the outer tube 12 and the inner tube 14.

[0032] During this process, the electromagnet 51 is energized in stages. When the electromagnet 51 is energized, the electromagnet 51 repels the magnetic clamp 50, so that the two magnetic clamps 50 overcome the pulling force of the tension spring 52 and approach each other to clamp the central shaft 21. At this time, the spiral blades 22 remain prohibited as the central shaft 21 is clamped, and the inner tube 14 is in a rotating state, so that the powdered additive in the storage barrel 11 is transported downward into the inner tube 14 under the relative rotation of the inner tube 14 and the spiral blades 22, and is discharged into the mixing disk 13 through the inner tube 14.

[0033] The additive is mixed with the sewage in the mixing disk 13. As the mixing disk 13 rotates, the additive and the sewage in the mixing disk 13 are evenly mixed. Due to the rotation of the arc partition 132, the additive and sewage mixture in the mixing disk 13 is discharged from the drain port 131 under the action of centrifugal force.

[0034] As the sewage in the mixing tray 13 is discharged, the external sewage flows into the mixing tray 13 through the water inlet 121 and mixes with the additives newly discharged into the mixing tray 13. As the mixing tray 13 moves along the lower guide rail 40, the additives are evenly mixed with the sewage.

[0035] When the lower movable seat 41 moves from one end of the lower guide rail 40 to the other end, the third motor 42 stops, and the roller 32 starts at this time, thereby driving the second motor 31 to rotate, and then driving the upper movable seat 102 to move a distance along the upper guide rail 30, the second motor 31 is turned off, and then the third motor 42 starts to reverse, thereby driving the mixing disk 13 to move in the opposite direction along the lower guide rail 40 to the initial end, and so on, so that the mixing disk 13 moves along an "S"-shaped path in the sewage treatment tank, cooperates with the mixing disk 13 to mix the sewage and additives and discharge them into the sewage treatment tank, thereby accelerating the mixing speed of the additives and the sewage treatment tank.

[0036] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention. All of these modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
