Description

Technical Field

[0001] The present application relates to the field of sewage treatment, and particularly to a chemical dosing tank for sewage treatment. Background Art

[0002] In modern industrial production and daily life, a large amount of various types of sewage will be generated, which contains a large amount of organic matter, microorganisms, etc. If discharged into nature, it will cause eutrophication of water bodies, trigger a large number of reproductions of algae and other aquatic plants, consume oxygen in the water, cause water hypoxia, and even produce odor and death phenomena. If such sewage is directly discharged without treatment, it will cause serious harm to the environment and human health. After the sewage is treated, it can be transformed into normal industrial water or domestic water that meets the regulations. Therefore, it is necessary to purify the sewage. Existing sewage treatment mostly uses sewage treatment ponds, and the sewage is treated in a biological or chemical form. Among them, a chemical dosing tank is mostly used to mix the chemicals for sewage treatment. Since a large amount of chemicals are used in sewage treatment, the chemical solution needs to be prepared and stored in advance. Therefore, the current chemical dosing tank mainly uses plastic materials to reduce costs and is equipped with a stirring device. However, when the chemical solution is stored after mixing, the stirring device is idle, increasing the production cost. At the same time, the stirring device being soaked in the chemical solution for a long time may cause the properties of the chemical solution to change, affecting the sewage treatment effect and efficiency.

[0003] For example, a chemical dosing tank for sewage treatment with the publication number of CN217516695U has a structure including a tank body, a high-pressure pump and a stirring device installed at the top of the tank body. One side bottom of the tank body is installed with a medicine delivery pipe, and the other end of the medicine delivery pipe is fixedly connected to the water inlet of the high-pressure pump. An installation hole is opened at the center of the top of the tank body. The stirring device includes an installation frame detachably installed at the top of the tank body, a stirring shaft installed on the installation frame, and a stirring motor for driving the stirring shaft to rotate. The bottom of the stirring shaft extends into the tank body through the installation hole. Stirring blades are hinged to both sides of the bottom of the stirring shaft, and connecting rods are hinged to the top surfaces of the two stirring blades. The above-mentioned chemical dosing tank only plays the role of installing and extracting the stirring shaft, which is not convenient for actual operation. Therefore, the present application designs a chemical dosing tank for sewage treatment that can automatically lock the tank body according to the stirring situation and is convenient for installation and disassembly.

By pushing the strip slider 14 at the bottom of the barrel body 1 into the slide groove 241 provided on the lower support plate 24, the barrel body 1 is stably pushed to the top of the lower support plate 24, and the arc-shaped positioning plate 15 collides with the locking pin 242 with the pushing, so that the barrel body 1 stops moving, and the locking pin 242 is in a coaxial position with the driven column 5 and the stirring mechanism 3 inside the barrel body 1.

[0031] See also Figure 2 as well as Figure 6 As shown, the stirring mechanism 3 includes a motor 31, a rotating rod 32, a stirring paddle 33 and a driving column 34. The lower end of the motor 31 is bolted to the upper support plate 21, and the output end of the motor 31 is plugged into the upper end of the rotating rod 32.

[0032] As another example, Figures 6 to 9As shown, a thread 7 is provided on the outer wall of the lower part of the driven column 5. The lower part of the thread 7 is a flat thread. The driven column 5 is rotatably connected to the barrel 1. The locking mechanism 4 is threadedly connected to the driven column 5. An annular seal is provided at the lower end inside the barrel 1, and the annular seal is provided on the outer wall of the driven column 5.

[0033] See Figures 6 to 8 , the locking mechanism 4 includes a thread ring 43, a locking column 44 and a spring-back rod 45; the upper end of the spring-back rod 45 is inserted into the lower end of the barrel 1, the lower end of the spring-back rod 45 is fixedly connected to the locking column 44, the thread ring 43 is threadedly connected to the lower part of the driven column 5, the upper end of the locking column 44 is inserted into the lower end of the thread ring 43, the locking column 44 is of a hollow design, and locking holes 441 are provided in a circumferential arrangement on the inner wall of the locking column 44.

When the driven column 5 rotates, it drives the thread ring 43 threadedly connected to the driven column 5 to move, and then drives the locking column 44 inserted into the thread ring 43 to move downward. The fixed connection between the locking column 44 and the spring-back rod 45 can prevent the thread ring 43 from rotating. The displacement of the locking column 44 drives the spring-back rod 45 to extend. As the locking column 44 descends, the locking column 44 meshes with the locking pin 242, and then locks the barrel 1 above the lower bearing plate 24 to realize automatic locking of the barrel 1 during the stirring operation.

[0034] See Figure 9 , the spring-back rod 45 includes an outer rod 451, an L-shaped inner rod 452 and a second spring 453.

[0035] Working principle: When in use, first lift the stirring mechanism 3 to a certain height through the electric telescopic rod 23, and then push the strip-shaped slider 14 at the lower part of the barrel body 1 into the chute 241 through the universal wheel 13. Stop pushing when the arc-shaped positioning plate 15 collides with the locking pin 242. Lower the stirring mechanism 3 through the electric telescopic rod 23 and extend it into the barrel body 1 through the stirring port 11, and make the driving column 34 engage with the driven column 5, and push the driven column 5 to displace downward, so that the locking hole 41 at the lower part of the driven column 5 engages with the strip-shaped protrusion 2421 to lock the barrel body 1. Then, pure water and medicine are transported into the barrel body 1 through the water inlet and the medicine inlet. Start the motor 31 and use the stirring paddle 33 to mix the liquid medicine.
