Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment box for sewage treatment. Background Art

[0002] Sewage treatment can be divided into primary treatment, secondary treatment and tertiary treatment according to the degree of treatment.

[0003] The primary treatment is mainly to remove suspended solid matter in sewage, and physical methods are commonly used. Generally, sewage that has undergone secondary treatment can meet the discharge standards, and activated sludge method and biofilm treatment method are commonly used. The purpose of tertiary treatment is to further remove certain special pollutants, such as fluoride removal, phosphorus removal, etc., which belongs to deep treatment and chemical methods are commonly used. During the treatment process, it is usually necessary to add a well-proportioned drug to the sewage. The drug usually exists in solid form, such as granules or tablets. These solid drugs are not easy to mix fully with the sewage due to factors such as density, size, and shape when they are added to the sewage, which will cause the drug to be unable to fully dissolve, thereby affecting the purification effect of the sewage and making it impossible for the sewage inside the sewage tank to be completely purified.

[0004] For this purpose, we propose a sewage treatment tank for sewage treatment. Utility Model Content

[0024] Embodiment: A sewage treatment tank for sewage treatment, such as Figure 1-Figure 3 As shown, it includes a sewage treatment tank 1, the center of the bottom of the sewage treatment tank 1 is connected with a sewage discharge pipe 101, one side of the sewage treatment tank 1 is connected with a water outlet pipe 102 near the bottom, a crushing cylinder 3 is provided on the top of the sewage treatment tank 1, the right end of the crushing cylinder 3 is fixedly connected with a fixed frame 302, a crushing assembly 303 is provided on the fixed frame 302, a filter screen 301 is installed in the middle of the inner cavity of the crushing cylinder 3, the crushing assembly 303 can crush the solid medicine on the crushing cylinder 3, the bottom of the crushing cylinder 3 is connected with a lower hopper 304, the lower hopper 304 is a Y-shaped structure as a whole, a vibration motor 305 is installed on the side wall of the lower hopper 304, the bottom of the lower hopper 304 is connected with a mixing cylinder 4, the left side wall of the mixing cylinder 4 is fixedly connected with a first drive motor 401, the first drive The output shaft end of the motor 401 is located in the inner cavity of the mixing barrel 4 and is fixedly connected to a mixing shaft 403, to which a spiral blade 404 is fixedly connected. An inlet pipe 405 is connected to one end of the top of the mixing barrel 4 close to the first drive motor 401, and a discharge pipe 402 is connected to the end of the bottom of the mixing barrel 4 away from the first drive motor 401. The bottom of the discharge pipe 402 is connected to the top of the sewage treatment tank 1. The spacing of the spiral blades 404 close to the first drive motor 401 is greater than the spacing away from the first drive motor 401. The design of the spacing of the spiral blades 404 from wide to narrow makes the pressure of the spiral blades 404 gradually increase, which can increase the friction and extrusion between the blades, and is conducive to better mixing and dissolving of drugs and sewage.

[0025] A counterweight 2 is fixedly connected to the side wall surface of the sewage treatment tank 1 away from one end of the first drive motor 401. The counterweight 2 is arranged to prevent the sewage treatment tank 1 from tipping over due to uneven gravity. A second drive motor 5 is fixedly connected to the center position of the front wall surface of the sewage treatment tank 1. The output shaft end of the second drive motor 5 is located in the inner cavity of the sewage treatment tank 1 and is fixedly connected to a stirring shaft 501. A plurality of stirring blades 502 are fixedly connected to the side wall surface of the stirring shaft 501. Through the cooperation of the stirring shaft 501, the stirring blades 502 and the second drive motor 5, the medicine and sewage in the inner cavity of the sewage treatment tank 1 are fully mixed.

[0026] The working principle of this utility model:

[0027] When in use, the granular medicine is placed on the filter 301 and the granular medicine is ground by the crushing component 303. The ground medicine is easier to mix with sewage and enters the mixing barrel 4 through the lower hopper 304. At this time, the sewage enters the inner cavity of the mixing barrel 4 through the water inlet pipe 405. The spiral blades 404 on the mixing shaft 403 are driven by the first drive motor 401 to mix the ground powder and sewage in the inner cavity of the mixing barrel 4. The sewage with the preliminary mixture of medicine enters the inner cavity of the sewage treatment tank 1 through the lower pipe 402, and the second drive motor 5 is started to drive the stirring blades 502 on the stirring shaft 501 to perform secondary mixing.

[0028] When in use, the spacing of the spiral blades 404 is designed to gradually become narrower, so that the pressure of the spiral blades 404 gradually increases, which can increase the friction and squeezing effect between the blades, and is conducive to better mixing and dissolving of the medicine and sewage.
