DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a multi-stage treatment device for chemical wastewater, comprising a treatment device body 1; in order to solve the problem of insufficient reaction between harmful substances and chemical treatment agents and incomplete wastewater treatment during wastewater treatment, a plurality of reaction tanks 2 are arranged on the treatment device body 1, a water pump 21 is installed between two adjacent reaction tanks 2, a card plate 22 is installed in each reaction tank 2, a stirring mechanism 3 and a de-impurity mechanism 4 are arranged on the card plate 22, the stirring mechanism 3 drives a stirring rod 39 to fully stir the wastewater and the chemical treatment agent in the reaction tank 2, so that the harmful substances are fully treated, and then the de-impurity mechanism 4 is used to clean the floating objects generated by the reaction;

[0023] In order to make the sewage and the chemical treatment agent react fully, the stirring mechanism 3 includes an energy pack 31, which is located on the inner side of the card plate 22. Both sides of the energy pack 31 are provided with telescopic grooves 32, and a slide bar 35 is slidably installed in the telescopic groove 32. A spring 37 is installed in the telescopic groove 32. One end of the spring 37 is installed on the inner wall of the telescopic groove 32, and the other end of the spring 37 is installed on the slide bar 35. A roller 36 is installed on the other end of the slide bar 35. A roller rail 23 is installed on the side of the card plate 22. The roller rail 23 is adapted to the roller 36. The energy pack 31 is provided with a plurality of rollers. A motor 33 is installed at the bottom, a driving gear disc 34 is installed on the motor 33, a gear ring 24 is installed on the side of the card plate 22, the driving gear disc 34 meshes with the gear ring 24, a connecting rod 38 is installed on the top of the energy pack 31, a stirring rod 39 is installed on the connecting rod 38, and the stirring rods 39 are evenly distributed on the connecting rod 38, the roller rail 23 is located above the gear ring 24, the roller rail 23 and the gear ring 24 are rings with the same track, the two rollers 36 located on the same side are a group, and the same group of rollers 36 are located at the top and bottom of the roller rail 23 respectively. When chemical wastewater is subjected to multi-stage treatment, the wastewater will enter different reaction tanks 2 in sequence, react with different chemical components in different reaction tanks 2, and gradually treat harmful substances contained in the wastewater. When the wastewater reacts in each reaction tank 2, the energy pack 31 provides energy to the motor 33 at the bottom, so that the motor 33 drives the driving gear disc 34 to rotate. Under the meshing action of the driving gear disc 34 and the gear ring 24 on the side wall of the card plate 22, and the limit formed by the roller 36 and the roller slide rail 23, the connecting rod 38 is finally driven along the track of the roller slide rail 23. The connecting rod 38 moves with the stirring rod 39 in the reaction tank 2, and the sewage in the reaction tank 2 is continuously stirred, so that the sewage and the chemical additives in the reaction tank 2 react fully, and the harmful substances in the sewage react completely. When the connecting rod 38 moves, the fixing frame 42 fixed on the connecting rod 38 is at the liquid surface of the sewage. By fixing the scoop net on the fixing frame 42, floating objects on the liquid surface can be collected, and floating objects such as foam generated in the chemical reaction process can be collected to prevent the floating objects from eventually adhering to the inner wall of the reaction tank 2 and being difficult to clean.

[0024] The working principle is as follows: when chemical wastewater is subjected to multi-stage treatment, the wastewater will enter different reaction tanks 2 in sequence, react with different chemical components in different reaction tanks 2, and gradually treat harmful substances contained in the wastewater. When the wastewater reacts in each reaction tank 2, the energy pack 31 provides energy to the motor 33 at the bottom, so that the motor 33 drives the driving gear disc 34 to rotate. Under the meshing action of the driving gear disc 34 and the gear ring 24 on the side wall of the card plate 22, and the limit formed by the roller 36 and the roller slide rail 23, the connecting rod 38 is finally driven along the roller slide rail 2 3, so that the connecting rod 38 drives the stirring rod 39 to move in the reaction tank 2, continuously stirring the sewage in the reaction tank 2, so that the sewage and the chemical additives in the reaction tank 2 react fully, and the harmful substances in the sewage react completely. When the connecting rod 38 moves, the fixing frame 42 fixed on the connecting rod 38 is at the liquid surface of the sewage. By fixing the scoop net on the fixing frame 42, floating objects on the liquid surface can be collected, and floating objects such as foam generated in the chemical reaction process can be collected to prevent the floating objects from eventually adhering to the inner wall of the reaction tank 2 and being difficult to clean.

[0025] Example 2: Figure 4 In order to prevent a large amount of foam from being generated when sewage reacts with chemical treatment agents, the impurity removal mechanism 4 includes a collar 41, which is sleeved on the connecting rod 38, and the collar 41 is located above the stirring rod 39. The stirring rod 39 and the collar 41 are located on the outside of the card plate 22. A fixing frame 42 is installed on the collar 41, and a scoop net is sleeved on the fixing frame 42. When the connecting rod 38 moves, the fixing frame 42 sleeved and fixed on the connecting rod 38 is at the liquid surface of the sewage. By fixing the scoop net on the fixing frame 42, floating objects on the liquid surface can be collected, and floating objects such as foam generated during the chemical reaction can be collected to prevent the floating objects from eventually adhering to the inner wall of the reaction tank 2 and being difficult to clean.
