The transposition drive can actively drive the stirring assembly 6 to perform transposition stirring, and the rotation drive drives the stirring assembly 6 to rotate and stir.

[0049] In this technical solution, through the setting of the sewage efficient dissolving and stirring mechanism 5, the stirring component 6 will rotate and move in the sewage treatment tank 1 for mixing, thereby increasing a variety of treatment methods, so that the sewage can be blasted in an irregular mixing manner and fully mixed with the treatment agent, thereby improving the mixing efficiency and, at the same time, improving the reaction effect.

[0050] In the present invention, the shifting drive includes a track block 7 , a transmission gear 8 , a driving gear 9 , a sliding limit block 10 , a cam 13 and a first motor 15 .

[0051] A case 14 is fixedly arranged above the case cover 4, a first motor 15 is fixedly arranged inside the case 14, and an output shaft of the first motor 15 passes through the case 14 and extends to the bottom of the case cover 4; a driving gear 9 is coaxially fixedly arranged on the output shaft of the first motor 15.

[0052] A transmission gear 8 is fixedly arranged above the track block 7 , and the transmission gear 8 is meshed with the driving gear 9 .

[0053] A sliding limit block 10 is rotatably provided on the outer side of the transmission gear 8 through a pin shaft, and a limit groove 11 is provided at the lower part of the box cover 4; the sliding limit block 10 is slidably provided in the limit groove 11;

[0054] The outer wall of the track block 7 is provided with a track groove 12 , and a cam 13 is slidably arranged inside the track groove 12 . The cam 13 is connected and fixed to the axis of the driving gear 9 .

[0055] Furthermore, the transmission gear 8 and the track groove 12 are both elongated in the middle and arc-shaped on both sides; the track groove 12 is a closed ring structure.

[0056] In this technical solution, the motion track of the stirring assembly 6 is made the same as that of the transmission gear 8. The square track of the stirring assembly 6 can be achieved by the rotation of the driving gear 9.

[0057] Furthermore, a placement groove 16 is provided inside the track block 7, and a placement box 17 is slidably arranged inside the placement groove 16.

[0060] In this technical solution, through the setting of the placement box 17, as the stirring begins, the activated carbon will slowly fall into the sewage treatment tank 1, instead of entering in a cluster, but scattered, avoiding the phenomenon of clumping and the lack of sufficient contact. It can be easily taken out by pressing and pushing multiple times.

[0061] It is worth noting that a slider 22 is slidably arranged in the inner wall of the placement groove 16, a spring C23 is fixedly connected to the outer wall of the slider 22, one end of the spring C23 is fixedly connected to the outer wall of the stopper 20, and the inclined surfaces of the stopper 20 and the slider 22 are in opposite directions.

[0062] In this technical solution, the arrangement of the slider 22 and the spring C23 enables the staff to remove the placement box 17 by pushing the placement box 17 and then pulling the placement box 17 to replace and add active carbon.

[0063] In the present invention, two groups of stirring assemblies 6 are provided, and the stirring assemblies 6 include a rotating shaft 24 , a stirring plate 25 , a bevel gear A 27 , a bevel gear B 28 and a second motor 29 .

[0064] The outer wall of the rotating shaft 24 is slidably and rotatably connected with a plurality of stirring plates 25;

[0065] A mechanical cavity 26 is opened inside the track block 7, and a second motor 29 is fixedly installed inside the track block 7; a bevel gear B28 is fixedly installed on the output shaft of the second motor 29, and the upper end of the rotating shaft 24 extends through the outer wall of the track block 7 to the inside of the mechanical cavity 26 and is coaxially fixedly connected with the bevel gear A27, and the bevel gear A27 and the bevel gear B28 are meshed.

[0066] In this technical solution, the second motor 29 drives the bevel gear B28 to rotate, thereby driving the rotating shaft 24 to rotate. The setting of the bevel gear B28 reserves space for fixing the drive shaft 30, that is, provides space for other mechanical movements.

[0067] In the present invention, the interior of the rotating shaft 24 is a hollow structure, and the rotation drive includes a driving shaft 30 , a pulley 32 and a crankshaft 33 .

[0068] The driving shaft 30 is rotatably arranged inside the rotating shaft 24; the upper end of the driving shaft 30 is fixedly arranged below the track block 7, and a plurality of rotation adjustment grooves 31 are provided outside the driving shaft 30, and a pulley 32 is slidably connected inside the rotation adjustment groove 31, and a crankshaft 33 is fixedly connected to one end of the pulley 32, and the other end of the crankshaft 33 extends to the outside through the inner wall of the rotating shaft 24 through a fixing rod and is connected and fixed to one side of the corresponding stirring plate 25; the two driving shafts 30 are connected and fixed by a stabilizing plate 34. The stabilizing plate 34 is slidably arranged at the bottom of the sewage treatment tank 1.

[0069] In the present invention, the rotation adjustment groove 31 is arranged around the outer wall of the driving shaft 30 , and the two sides of the rotation adjustment groove 31 are arranged in a semicircular structure, and are formed into two upper and lower semicircles, which are connected to form a closed shape.

[0070] In this technical solution, by setting the driving shaft 30, each stirring plate 25 can be driven to rotate in the horizontal direction to drive the sewage in the adjacent area to be stirred to further accelerate the mixing and improve the reaction effect.

[0071] The working principle of the present invention is as follows: first, add additives such as activated carbon into the placement box 17, then, by pushing the placement box 17, the clamp head 18 will pass through the slider 22, and at this time, pull the handle on the placement box 17, because the pressure spring C23 will stick to the stopper 20, the clamp head 18 will slide to the side of the stopper 20 through the slider 22, remove the placement box 17 and put in the active carbon, at this time, push the placement box 17, the clamp head 18 on it slides over the stopper 20 to get stuck at the surface of the stopper 20;

[0072] When the sewage treatment equipment is needed, sewage is injected through the water inlet 3. At this time, the output shaft of the first motor 15 is driven by the controller to rotate, which drives the driving gear 9 to rotate. The driving gear 9 is meshed with the transmission gear 8, and is restricted in the track groove 12 by the cam 13 on the transmission gear 8, so that the driving gear 9 and the transmission gear 8 are always meshed. At this time, the track block 7 cooperates with the sliding limit block 10 rotatably set on the track block 7, and the track block 7 will move with the stirring assembly 6 to stir and mix;

[0073] At the same time, the output shaft of the second motor 29 is driven to rotate, driving the corresponding bevel gear B28 to rotate, and then the rotating shaft 24 is driven to rotate by meshing with the bevel gear A27, so that the stirring plate 25 revolves on the rotating shaft 24 while moving. At the same time, since the rotating shaft 24 rotates around the driving shaft 30, and the driving shaft 30 is provided with a rotation adjustment groove 31, the setting of the special groove of the rotation adjustment groove 31 allows the crankshaft 33 to flip back and forth, thereby driving the stirring plate 25 fixed on the crankshaft 33 to flip and stir the reaction, thereby improving the stirring effect.
