[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device convenient for dosing coagulants. Background Technique

[0002] Coagulants have important applications in sewage treatment. Their main function is to coagulate water-soluble pollutants into tiny insoluble substances for subsequent treatment. Common coagulants include polyaluminum chloride (PAC), aluminum sulfate, ferric sulfate, ferric chloride, polyacrylamide, etc. Among them, polyaluminum chloride has good coagulation performance, forms large flocs, requires less dosage, has high efficiency, fast sedimentation, is suitable for a wide range of water qualities, and is mainly used for the purification of drinking water and industrial water supply. Polacrylamide can adapt to a variety of flocculation objects, has less dosage, high efficiency, generates less sludge, and is easy to post-treat.

[0003] Chinese patent with publication number CN212581578U discloses a device for uniformly dosing coagulants for sewage treatment, including a pipeline. The bottom end of the pipeline is equidistantly communicated with connecting pipes, the bottom ends of the connecting pipes are threadedly connected with spraying heads, and brackets are clamped and fixed at the bottom of both sides of the pipeline.

[0004] The above-mentioned existing technical solutions have the following defects: Although the device is designed with equidistantly communicated connecting pipes and spraying heads, due to the properties of coagulants and the flow characteristics of pipelines, there may still be problems with uneven dosing of coagulants. This will affect the effect and stability of sewage treatment, and the coagulants cannot quickly and evenly contact and react with pollutants in water.

[0005] Therefore, we propose a sewage treatment device convenient for dosing coagulants to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-7 , the present invention provides a technical solution: a sewage treatment device facilitating the dosing of coagulants, including a sewage tank 1, which serves as the main container for sewage treatment and is used to hold the sewage to be treated. A drainage pipe 2 is fixedly connected to the right side of the sewage tank 1, and the drainage pipe 2 is used to discharge the treated sewage. A dosing mechanism is arranged inside the sewage tank 1, and the dosing mechanism includes a stirring unit and a cleaning unit;

[0029] The stirring unit includes a rotating shaft 6, a mounting opening 601, a spoiler 3, spoiler holes 301, mounting holes 302, a spraying head 4, a base 5, and a motor 501. The bottom of the base 5 is fixedly connected to the inner bottom surface of the sewage tank 1. The base 5 provides a stable support for the motor 501 and also ensures the stable rotation of the rotating shaft 6. The motor 501 is fixedly connected inside the base 5. The motor 501 is the power source of the entire stirring unit. It drives the rotation of the rotating shaft 6, thereby realizing the stirring of the sewage and the dosing of the coagulant. The output end of the motor 501 penetrates through the base 5 and is rotatably connected to the bottom of the rotating shaft 6. The rotating shaft 6 is the core component of the stirring unit. The rotation of the rotating shaft 6 drives the entire stirring process. It allows the spoiler 3 and the spraying head 4 to rotate, thereby realizing the uniform mixing of the sewage and the uniform dosing of the coagulant. Mounting openings 601 are provided around the rotating shaft 6, and the spoiler 3 is snap-fitted into the mounting openings 601. There are four spoiler plates 3, and a plurality of spoiler holes 301 are equidistantly arranged on the spoiler plates 3. The design of the spoiler plates 3 helps to form an effective spoiler effect in the sewage tank, increasing the contact area and mixing degree between the sewage and the coagulant. The spoiler holes 301 on the spoiler plates 3 enhance the spoiler effect and further promote the mixing effect. There are four groups of spraying heads 4, which are respectively arranged in the middle of two spoiler plates 3. Each group of the spraying heads 4 has four and is equidistantly arranged on the outer surface of the rotating shaft 6. The arrangement of the spraying heads 4 ensures that the coagulant can be evenly sprayed into the sewage, thereby improving the coagulation effect. Each group of four spraying heads 4 that are equidistantly arranged on the outer surface of the rotating shaft 6 ensures the uniform distribution of the coagulant.

[0030] The installation openings 601 are provided on the upper and lower sides of the spoiler 3. The spray head 4 is fixedly connected to the outside of the rotating shaft 6. The upper and lower sides of the installation openings 601 are provided with clamping structures. The clamping structure includes a support plate 801, a spring 802, a second clamping block 803 and a support column 804. The upper surface of the support plate 801 is fixedly connected to the outer wall of the rotating shaft 6 at the middle inside. The top of the support column 804 is fixedly connected to the bottom of the support plate 801. The spring 802 is arranged inside the support column 804. The top of the second clamping block 803 is fixedly connected to the bottom of the spring 802. The clamping structure provides the function of quickly installing and disassembling the spoiler 3. The introduction of the spring 802 provides an automatic clamping function, ensuring the stable installation of the spoiler 3;

[0031] The cleaning unit includes a connecting strip 901, a connecting block 902, a clamping hole 903 and a scraping plate 904. The upper surface of the scraping plate 904 is fixedly connected to the lower surface of the left side of the connecting strip 901. The scraping plate 904 is closely attached to the surface of the rotating shaft 6 and can thoroughly scrape off the attached coagulant, thus keeping the rotating shaft 6 clean and the system running normally. The lower surface of the connecting block 902 is fixedly connected to the right end of the connecting strip 901. The clamping hole 903 is opened on the upper surface of the connecting block 902, and the clamping hole 903 is convex.

[0032] The upper surface of the rotating shaft 6 is provided with a top cover 7. The design of the top cover 7 not only protects components such as the rotating shaft 6 and the connecting block 902 from sewage erosion, but also is connected to the cleaning unit through the clamping structure (the first clamping block 702) inside it. It ensures the stable installation of the cleaning unit and simplifies the installation and disassembly process. A placement groove 70 is opened in the middle of the bottom surface of the top cover 7. The top end of the fixing strip 701 is fixedly connected to the middle of the placement groove 70. The upper surface of the first clamping block 702 is fixedly connected to the bottom end of the fixing strip 701. The placement groove 70 fits tightly with the connecting block 902. The first clamping block 702 is clamped inside the clamping hole 903. The tight fit between the placement groove 70 and the connecting block 902 ensures that the first clamping block 702 can accurately be inserted into the clamping hole 903, further enhancing the stability of the connection. This design improves the maintenance efficiency and reduces the failures caused by loosening or falling off.

[0033] Working principle: Open the water inlet of the sewage tank 1 and inject the sewage to be treated into the tank. Start the motor 501, and the motor 501 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the spoiler 3 and the spray head 4 to rotate together. The design of the spoiler 3 enables the sewage to form effective turbulence in the tank, and the turbulence holes 301 increase the contact area and mixing degree between the sewage and the coagulant. The spray head 4 evenly sprays the coagulant into the sewage to further improve the coagulation effect. Adjust the rotation speed of the motor through the control system to adapt to different treatment requirements. At the same time, put the coagulant inside the rotating shaft 6 and evenly put it into the sewage through the spray head 4. During the sewage treatment process, regularly stop the operation of the motor 501, connect the cleaning unit to the connection hole 903 of the connection block 902 through the clamping structure, start the motor inside the top cover 7, and drive the connecting bar 901 to drive the scraper 904 to scrape off the residual coagulant inside the rotating shaft 6. After a period of treatment, the pollutants in the sewage form flocs with the coagulant and settle. At this time, open the valve of the drainage pipe 2 and discharge the treated sewage.
