DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] Embodiment 1:

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A production wastewater treatment device includes a treatment box 1, and also includes: a filter cartridge 2 arranged in the treatment box 1; a hollow shaft 3, rotatably connected to the side wall of the treatment box 1, wherein the filter cartridge 2 is fixedly connected to the hollow shaft 3; a gear 2 303, fixedly mounted on the hollow shaft 3; a motor 301, fixedly mounted on the side wall of the treatment box 1, wherein a gear 1 302 is fixedly mounted on the output end of the motor 301, and the gear 1 302 is meshingly connected with the gear 2 303; a hollow box 5, fixedly connected to the treatment box 1 and located directly above the filter cartridge 2, wherein an air jet nozzle 501 connected to the inner cavity is provided on the hollow box 5, a booster pump 502 is fixedly mounted on the outer wall of the treatment box 1, and the booster pump 502 is connected to the inner cavity of the hollow box 5 through a pipeline 503; an injection pipe 203, fixedly connected to the treatment box 1, wherein the injection pipe 203 passes through the hollow shaft 3 and one end located in the filter cartridge 2 is fixedly connected with a plurality of vertically downward branch pipes 204.

[0024] A rotating shaft 4 is rotatably connected inside the processing box 1, and a plurality of groups of toggle rods 401 are fixedly connected to the rotating shaft 4 at equal intervals. Each group of toggle rods 401 is provided with a plurality of them. One end of the rotating shaft 4 that passes through the processing box 1 is fixedly connected to a pulley at the output end of the motor 301, and the two pulleys are connected by a belt 402.

[0025] The system also includes an activated carbon filter 504 , which is fixedly installed in the input end of the booster pump 502 and is used to filter the external gas passing through the input end of the booster pump 502 .

[0026] When in use, the wastewater to be treated is added to the injection pipe 203, and the wastewater is discharged into the filter cartridge 2 through a plurality of branch pipes 204 connected to the injection pipe 203. A one-way valve is arranged on the injection pipe 203. At this time, the wastewater passes through the filter cartridge 2 and flows into the treatment box 1, and the impurities carried in the wastewater are blocked in the filter cartridge 2 when the wastewater passes through the filter cartridge 2, thereby filtering and removing impurities from the wastewater. Then the motor 301 is started, and the motor 301 is connected to the gear 1 302 and the gear 2 303 to drive the hollow shaft 3 to rotate, and the hollow shaft 3 drives the filter cartridge 2 to rotate synchronously, thereby increasing the contact surface between the filter cartridge 2 and the wastewater and improving the filtering efficiency of the wastewater. Subsequently, the booster pump 502 is started, and the booster pump 502 absorbs external gas to make When the external gas passes through the input end of the booster pump 502, it contacts with the activated carbon filter 504. Since the activated carbon has a developed pore structure and rich microporous tissues inside, these microporous tissues have a strong adsorption force field. When the gas contacts the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb the particles in the air into the micropores, thereby achieving the effect of purifying the gas. Then, the purified gas is transported into the hollow box 5 through the pipeline 503. A one-way valve is provided on the pipeline 503, and finally, it is ejected through the air nozzle 501 and then sprayed onto the surface of the filter cartridge 2, thereby achieving the reverse cleaning of the filter holes of the filter cartridge 2, thereby keeping the filter cartridge 2 unobstructed, preventing the filter holes of the filter cartridge 2 from being blocked, and reducing the efficiency of wastewater filtration;

[0027] Then, when an appropriate amount of treatment is added to the treatment box 1, the treatment liquid is mixed with the wastewater, thereby decomposing the harmful substances in the wastewater. At the same time, the rotating shaft 4 rotates synchronously following the running direction of the motor 301 through the belt 402, and the rotating shaft 4 drives the toggle rod 401 to rotate synchronously, and then the rotating toggle rod 401 stirs the treatment liquid and the wastewater, so that the treatment liquid and the wastewater are more fully mixed, thereby improving the effect of decomposing harmful substances in the wastewater, until the wastewater reaches the discharge standard, the filtration treatment of the wastewater can be stopped.

[0029] Reference Figure 1 , Figure 4 , a production wastewater treatment device, which is basically the same as Example 1, and further, one end of the filter cartridge 2 is open, and a cover plate 201 is detachably connected to the filter cartridge 2, and the cover plate 201 is used to close the opening on one end of the filter cartridge 2; it also includes a fixing bolt 202, and the cover plate 201 is detachably connected to the filter cartridge 2 through the fixing bolt 202.

[0030] When it is necessary to clean the impurities blocked in the filter cartridge 2, since the cover plate 201 is fixedly connected to the filter cartridge 2 by the fixing bolts 202, it is convenient for the staff to remove the cover plate 201 with the help of tools, and then open the opening on one end of the filter cartridge 2, thereby facilitating the staff to clean the impurities blocked in the filter cartridge 2.
