The rotating rod 6 rotates because the first gear 7 drives the second gear 8 to rotate, so that the rotating rod 6 rotates in the opposite direction to the rotating shaft 4, so that the rotating plate 10 and the stirring plate 5 rotate in the opposite direction. The directions of rotation are opposite, so that when the stirring plate 5 and the rotating plate 10 rotate to stir the wastewater and chemicals in the bottom shell 1, opposite vortices will be generated, so that the chemicals and substances in the wastewater can collide with each other, thereby accelerating the mixing reaction, and when the rotating shaft 4 rotates, because the rotating shaft 4 does not penetrate the outer wall of one end of the placement plate 2, a third bevel gear 12 is fixedly connected; the bottom ends of the outer walls of a pair of circular rods 11 are fixedly connected to fourth bevel gears 13, and the pair of fourth bevel gears 13 are meshed with the third bevel gear 12, so that the rotation of the rotating shaft 4 drives the pair of fourth bevel gears 13 and the pair of circular rods to rotate through the third bevel gear 12, so that the rotation of the circular rod drives the auxiliary plate 14 to rotate, and because the circular rod 11 is inclined, when the circular rod 11 drives the auxiliary plate 14 to rotate, the auxiliary The vortex generated by the rotational force of the plate 14 and the flow of the liquid are inclined, and when the rotating rod 6 rotates, the rotation of the rotating rod 6 will drive a group of first rotating rods 9 and the rotating plate 10 to perform circular motion around the rotating rod 6, because the inner side wall of the bottom shell 1 is fixedly connected with a pair of fifth bevel gears 16 through a pair of first circular rods, and the pair of fifth bevel gears 16 are respectively located in a pair of circular grooves 15; one end of the outer wall of the two groups of first rotating rods 9 located in the circular grooves 15 is fixedly connected with a sixth bevel gear 17, and the two groups of sixth bevel gears 17 are respectively meshed with the pair of fifth bevel gears 16, so that when the first rotating rod 9 rotates around the rotating rod 6, the rotation of the first rotating rod 9 will drive the sixth bevel gear 17 to rotate, while the fifth bevel gear 16 is stationary, and the fifth bevel gear 16 and a group of sixth bevel gears The wheels 17 mesh with each other, so that when the sixth bevel gear 17 follows the rotation of the first rotating rod 9, a group of sixth bevel gears 17 will rotate, and the rotation of the sixth bevel gear 17 will drive the first rotating rod 9 and the rotating plate 10 to rotate, so that the rotating plate 10 rotates vertically while rotating horizontally, so that the bidirectional rotation of the rotating plate 10 not only increases the mixing efficiency of the substances and chemicals in the wastewater, but also increases the stirring range of the rotating plate 10. Because the pair of circular rods 11 and the pair of rotating rods 6 are distributed in a circle, the rotation of the rotating shaft 4 and the pair of circular rods 11 and the rotating rod 6 cooperates with each other, so that the stirring plate 5 and the rotating plate 10 move in opposite directions on a straight line to accelerate the mixing efficiency, and the bidirectional rotation of the rotating plate 10 further improves the mixing efficiency.And the stirring plate 5 and the auxiliary plate 14 rotate on another straight line, and the inclined vortex generated by the rotation of the auxiliary plate 14 also accelerates the mixing and stirring efficiency, and the two straight lines are in a cross shape, so that they cooperate with each other, so that the stirring effect and the mixing reaction efficiency of the device are further improved, thereby saving the time required for stirring and mixing while reducing energy consumption, and when the chemical agent is mixed with the substances in the wastewater, some of the substances in the wastewater will precipitate, and some will float on the water surface. The floating objects on the water surface are impurities and substances that affect the water quality. When the rotating shaft 4 rotates, the rotation of the rotating shaft 4 will drive the cleaning shell 19 to rotate through the sliding plate 18. Because one side of the outer wall of the cleaning shell 19 is open, the floating objects will be The cleaning shell 19 is entered into through the opening on the cleaning shell 19. Since the bottom end of the inner wall of the opening of the cleaning shell 19 is an inclined surface, impurities and substances that affect water quality can enter the cleaning shell 19 more easily and are not easily blocked. Since the bottom end of the outer wall of the cleaning shell 19 is fixedly connected with the collecting shell 20, and the collecting shell 20 is connected with the cleaning shell 19, the floating objects will fall into the collecting shell 20 for storage after entering the cleaning shell 19. Since the collecting shell 20 is below the cleaning shell 19, the floating objects are not easy to flow out of the cleaning shell 19. Therefore, the cleaning shell 19 cooperates with the collecting shell 20 to clean and collect more floating objects. Moreover, a group of filtering holes 21 are opened at the bottom end of the outer wall of the collecting shell 20, so that the floating objects will be blocked by the bottom end of the inner wall of the collecting shell 20 and cannot flow out from the filtering holes 21. The waste water that can be purified again can flow out from the filter hole 21, thereby reducing the waste water that can be purified again, and making it difficult for the waste water that can be purified again to occupy space in the collection shell 20, so that the device can clean and collect the floating objects produced by the reaction while stirring and mixing the waste water, thereby reducing the workload of the staff to clean the floating objects, and the cleaning and collection of the floating objects is carried out while mixing and stirring, so that the device saves the time of cleaning the floating objects, and the cleaning and collection of the floating objects and the stirring and mixing are all completed by the first motor 3 driving the rotating shaft 4, so there is no need to use multiple power sources, thereby saving energy consumption, and because the top of the outer wall of the sliding plate 18 is provided with a placement slot 33; the outer wall of the cleaning shell 19 A placement block 34 is fixedly connected to one side, and the outer side wall of the placement block 34 is slidably placed on the inner side wall of the placement slot 33, so that the cleaning shell 19, the placement block 34 and the collection shell 20 can be disassembled and installed. When the cleaning shell 19, the collection shell 20 or other parts are damaged and need maintenance or cleaning, the stretching rod 39 can be pulled to make the stretching rod 39 drive the positioning block 38 to move out of the positioning slot 35, and release the fixing of the sliding plate 18 and the placement block 34. At this time, the placement block 34 and the cleaning shell 19 can be taken out of the placement slot 33 on the sliding plate 18, making the device more convenient for repairing or cleaning parts such as the cleaning shell 19 or the collection shell 20, and when the cleaning shell 19 or the collection shell 20 is damaged, there is no need to replace the entire device, only some parts need to be replaced.The replacement cost of the device is reduced, and the placement slot 33 is placed at the top of the sliding plate 18, so that the cleaning shell 19 and the placement block 34 are easier to take and place, and the placement block 34 and the sliding plate 18 are fixed by a clamping fixing structure, so that the placement block 34 and the cleaning shell 19 are more convenient to disassemble and install, and the second motor 24 drives the threaded shaft 25 to rotate. Since the threaded shaft 25 is threadedly connected to the sliding plate 18, the rotation of the threaded shaft 25 will cause the sliding plate 18 to move up and down, and the movement of the sliding plate 18 drives the cleaning shell 19 and the collecting shell 20 to move, so that the device can adjust the position of the cleaning shell 19 according to the water level of the wastewater, so that the cleaning shell 19 and the collecting shell 20 can be adjusted. 20 can better recycle and clean floating objects on the wastewater, and because the inner side wall of the square groove 22 is slidably connected with the sliding block 23, and one side of the outer wall of the sliding block 23 is fixedly connected to the inner side wall of the sliding plate 18, when the threaded shaft 25 rotates, the sliding plate 18 will not rotate, but will only move up and down, and when the rotating shaft 4 rotates, the sliding plate 18 and the cleaning shell 19 will be driven to rotate, so that the device can adjust the position of the cleaning shell 19 according to the water level of the wastewater, so that the cleaning shell 19 can effectively recycle and clean floating objects under different environments and needs, making the device more flexible and practical, and when the cleaning shell 19 rotates by rotating the rotating shaft 4, the rotation of the cleaning shell 19 will drive the second cleaning shell 19 on the cleaning shell 19 The rotating rod 30 and the seventh gear 31 rotate, because the inner wall of the bottom shell 1 is provided with a first slide groove 26; the inner wall of the first slide groove 26 is slidably connected with a fixed block 27; a ring gear bar 28 is fixedly connected to one side of the outer wall of the fixed block 27, and a group of seventh gears 31 and the ring gear bar 28 are meshed with each other, so that the ring gear bar 28 can only move up and down in the first slide groove 26 under the limit of the fixed block 27, but cannot rotate, and when the seventh gear 31 rotates around the rotating shaft 4, the seventh gear 31 is meshed with the ring gear bar 28, so that the seventh gear 31 rotates while rotating, thereby driving the second rotating rod 30 to rotate, so that the second rotating rod 30 drives the cleaning plate 32 to rotate, and the inner wall of the collection shell 20 is collected. The bottom is cleaned, so that floating objects are not easy to block the filter hole 21, and the waste water that can be purified can fall from the filter hole 21 more effectively and quickly. The connecting plates 29 are fixedly connected to the opposite sides of the outer wall of the sliding plate 18, and the top ends of the outer walls of a pair of connecting plates 29 are slidably connected to the bottom ends of the outer walls of the annular gear strip 28. When the sliding plate 18 moves up and down to drive the cleaning shell 19 to move up and down, the movement of the sliding plate 18 will also drive the annular gear strip 28 to move through the connecting plate 29, so that the seventh gear 31 is always meshed with the annular gear strip 28, so that the device not only has the effect of rapid stirring and mixing, but also has the function of cleaning and collecting floating objects, so that the device has strong practicality and functionality.
