[0019] It should be noted that the specific installation method of the motor 3, the connection method of the circuit and the control method in the present invention are all conventional designs, which are conventional design means of designers, and the filter component 4 is composed of an exhaust fan and a multi-layer air filter plate. When the exhaust fan is started, the gas in the inner cavity of the tank body 21 will be driven into the filter component 4, and the toxic, harmful and irritating gases generated in the reaction will be filtered through the multi-layer air filter plate in the filter component 4, and the exhaust fan is installed on the upper side of the multi-layer air filter plate. This device is used for the first filtration and the second filtration. In the initial stage of sewage treatment, it mainly removes large particles of solids and floating objects for filtration, and filters solid precipitates generated by the reaction of wastewater and chemical agents.

[0020] First, the chemical wastewater is discharged into the filter mechanism 8 for filtration, and large impurities such as large particles of solids and floating objects in the chemical wastewater are filtered. At the same time, the filter component 4 is started, and the filtered wastewater enters the reaction group 2 through the water inlet pipe 2 91. The airflow generated by starting the filter component 4 is blown into the filter mechanism 8 through the ventilation pipe 5, so that the large particles of solids, floating objects and other large impurities filtered in the filter mechanism 8 are blown into the sewage pipe 2 9 and discharged from the sewage pipe 2 9 to the outside of the device. In this process, there is no need to manually stop the machine to process the filtered impurities, which saves time and labor and improves work efficiency. Then, an appropriate amount of chemical agents is added to the wastewater through the reaction group 2, and the motor 3 is started.

In this process, the toxic, harmful and irritating gases generated are filtered through the filter component 4, and the generated precipitation is discharged from the bottom of the reaction group 2. The water after harmless treatment is discharged through the lower left part of the reaction group 2.

[0021] In order to achieve the first filtration of chemical wastewater, such as Figure 4 As shown, the filtering mechanism 8 includes an inlet pipe 81, a rotating impeller 82 is rotatably connected to the rear side of the inner cavity of the inlet pipe 81, a connecting plate 86 is fixedly connected to the middle of the upper end of the inlet pipe 81, a pulley 83 is provided on the upper end of the rotating impeller 82 and the left side of the upper end of the connecting plate 86, a separation group 85 is fixedly connected to the left end of the inlet pipe 81, and a bevel gear 84 is fixedly connected to the middle of the right side of the separation group 85 and the upper end of the pulley 83 on the left side.

[0022] First, the chemical and chemical wastewater flows from the right side of the water inlet pipe 81 to the left side, and impacts the rotating impeller 82, so that the rotating impeller 82 rotates at the rear side of the inner cavity of the water inlet pipe 81. The rotation of the rotating impeller 82 drives the pulley 83 fixed thereto to rotate, and with the cooperation of the belt, drives the pulley 83 rotatably connected to the connecting plate 86 to rotate together, thereby driving the two bevel gears 84 to rotate, and through the rotation of the bevel gear 84, drives the separation group 85 to operate, and the separation group 85 is used to filter the large particles of solids, floating objects and other large impurities in the chemical and chemical wastewater for the first time, and with the cooperation of the filter component 4 and the ventilation pipe 5, the filtered impurities are discharged from the outer surface of the device through the sewage pipe 9, and the filtered water passes through the separation group 85 and enters the reaction group 2 with the cooperation of the water inlet pipe 91, so as to achieve the purpose of filtering the chemical and chemical wastewater for the first time, and in this process, there is no need to manually stop the machine to process the filtered impurities, saving time and labor, and improving work efficiency.

[0023] Further explanation, such as Figure 5 and Figure 6As shown, the separation group 85 includes a sleeve disc 851, and a filter disc 853 is rotatably connected to the inner cavity of the sleeve disc 851. A through hole 854 is opened on the upper sides of the left and right ends of the sleeve disc 851, and a through hole 852 is opened on the lower sides of the left and right ends of the sleeve disc 851. The right end of the filter disc 853 penetrates the inner cavity of the sleeve disc 851 and is fixedly connected to the left end of the bevel gear 84 on the left side, the lower side of the left end of the sleeve disc 851 is fixedly connected to the right end of the water inlet pipe 91, the upper side of the left end of the sleeve disc 851 is fixedly connected to the right end of the ventilation pipe 5, the lower side of the right end of the sleeve disc 851 is fixedly connected to the left end of the water inlet pipe 81, and the upper side of the right end of the sleeve disc 851 is fixedly connected to the left end of the sewage pipe 9.

[0024] In detail, the rotation of the two bevel gears 84 will drive the filter turntable 853 to rotate in the inner cavity of the sleeve disc 851, and the wastewater enters the inner cavity of the sleeve disc 851 through the water inlet pipe 81 and the inner cavity of the through hole 852 on the right side, and is filtered by the filter turntable 853. During the filtering, the filter turntable 853 rotates to transport the filtered large particles of solids, floating objects and other larger impurities to the through hole 854. At the same time, with the coordinated use of the filter component 4 and the ventilation pipe 5, the generated airflow blows the impurities in the filter turntable 853 through the through hole 854, blows the impurities into the inner cavity of the sewage pipe 9, and discharges them from the sewage pipe 9 to the outside of the device, thereby realizing the first filtration of the wastewater.

[0025] To achieve the second filtering, Figure 7 As shown, the reaction group 2 includes a tank body 21, a rotating groove 23 is opened in the middle of the upper end of the tank body 21, a drug feed pipe 22 is fixedly connected to the front side of the middle of the upper end of the tank body 21, an exhaust hole 24 is opened in the rear side of the middle of the upper end of the tank body 21, a sewage pipe 27 is fixedly connected to the lower end of the tank body 21, a mounting frame 28 is fixedly connected to the lower side of the inner cavity of the tank body 21, a curved filter plate 26 is provided on the left side of the lower side of the inner cavity of the tank body 21, a water outlet pipe 25 is fixedly connected to the left side of the lower side of the outer surface of the tank body 21, the upper end of the exhaust hole 24 is fixedly connected to the lower end of the filter component 4, the lower side of the outer surface of the tank body 21 is fixedly connected to the inner cavity of the circular support frame 1, the left end of the water inlet pipe 91 is fixedly connected to the upper right side of the outer surface of the tank body 21, and the inner cavity of the water inlet pipe 91 is communicated with the inner cavity of the tank body 21.

[0026] It should be noted that the water outlet pipe 25 and the sewage pipe 27 are both composed of a drainage pipe and a valve. A hole adapted to the water inlet pipe 91 is also provided on the upper right side of the outer surface of the tank body 21. The filtered water enters the inner cavity of the tank body 21 through the water inlet pipe 91. Then, an appropriate amount of relevant chemical agents for harmless treatment of wastewater enters the inner cavity of the tank body 21 through the drug inlet pipe 22 to react with the wastewater. At the same time, the motor 3 is started to drive the bevel gear 6 to rotate, and the stirring mechanism 7 is driven by the bevel gear 6 to stir the wastewater and the relevant chemical agents. The reaction is carried out, and the toxic, harmful and irritating gases generated in the process are filtered through the bevel gear 6, and the harmless gases after filtration are discharged into the ventilation pipe 5. After the chemical agent and the wastewater are fully reacted, the wastewater is harmlessly treated, and the precipitate generated sinks to the bottom of the inner cavity of the tank body 21 after standing, and then the outlet pipe 25 is opened, and the harmless water is filtered through the curved filter plate 26, and the filtered water is discharged through the outlet pipe 25, and then the sewage pipe 27 is opened to discharge the precipitate from the sewage pipe 27, so as to achieve the purpose of the second filtration.

[0028] First, the upper side of the outer surface of the rotating long rod 71 and the lower side of the outer surface of the conical scraper 75 are respectively installed with the inner cavity of the rotating groove 23 and the inner cavity of the mounting frame 28 and can rotate. When the two bevel gears 6 rotate, the rotating long rod 71 will be driven to rotate, and the rotating long rod 71 will then drive the rectangular scraper 72, the stirring blade 73, the stirring group 74 and the conical scraper 75 to stir the wastewater and the chemical agent at the same time. The rectangular scraper 72 and the conical scraper 75 can not only stir the wastewater and the chemical agent, but also scrape off the sticky impurities in the middle and lower parts of the inner cavity of the tank body 21 respectively. In addition, while the stirring group 74 rotates to stir, it will also generate a large number of small air bags, so that the wastewater and the chemical agent react more fully, further shortening the wastewater treatment time and improving work efficiency.

[0029] Further explanation, such as Fig. 9 and Fig.10As shown, the two stirring groups 74 each include a mounting sleeve 743, two bolts 744 are provided on the front sides of the outer surfaces of the two mounting sleeves 743, six support rods 741 are fixedly connected in a circular array on the outer surfaces of the two mounting sleeves 743, and a conical sleeve column 742 is fixedly connected on the side of the six support rods 741 on the same side away from the mounting sleeve 743, and the two mounting sleeves 743 are fixedly connected to the lower side of the outer surface of the rotating long rod 71 by two bolts 744 respectively.

[0030] It should be noted that a threaded groove compatible with the bolt 744 is provided on the lower side of the outer surface of 17, so that the mounting sleeve 743 can be fixed to the lower side of the outer surface of the support rod 741 through the bolt 744. When the rotating long rod 71 drives the mounting sleeve 743 to rotate, the support rod 741 will be driven to stir the wastewater and the chemical agent, and in this process, the conical sleeve column 742 will generate a large number of small bubbles through the rotation of a number of conical sleeve columns 742. When the small bubbles float upward from the lower side of the waste liquid, the speed of contact between the wastewater and the chemical agent will be accelerated, so that the wastewater and the chemical agent will fully react.
