Description

A kind of reaction tank for sewage treatment

technical field

The utility model relates to the technical field of sewage treatment, in particular to a reaction tank for sewage treatment.

Background technique

Urban sewage contains a large amount of organic pollutants and inorganic pollutants. The treatment methods for organic pollutants include biofilm method, anaerobic biological treatment method and activated sludge method. At this stage, many urban sewage treatment plants use activated sewage. The sludge method, the treatment process is to mix activated sludge into the sewage to be treated, and let the microorganisms in the activated sludge decompose the organic pollutants in the sewage, so as to achieve the effect of decontamination.

The activated sludge method needs to mix the activated sludge with the sewage, so that the activated sludge can fully decompose the organic pollutants in the sewage. The treatment effect is not good, and some traditional pools are provided with stirring rods for stirring, but when cleaning the pools, the stirring will occupy a large space, which makes the operation more inconvenient.

To this end, we propose a reaction tank for sewage treatment to solve the above problems.

Compared with the prior art, the beneficial effects of the present utility model are:

1. By setting the telescopic cylinder and the sliding rod, the operating characteristic of the servo motor is that it can continuously change the rotation direction of the output shaft. When the servo motor rotates in one direction, the sliding rod will extend from the telescopic cylinder under the action of centrifugal force. Not only the telescopic cylinder itself can play a stirring role, but the sliding rod can also play a stirring role in the radial direction, which makes the stirring effect better, greatly improves the contact degree between the activated sludge and the sewage, and the treatment effect is better.

2. By setting the chaotic rod, when the sliding rod is driven to rotate back and forth in the tank body, the chaotic rod at the end will also move in a circle around the rotating shaft, which further improves the stirring effect and enables the activated sludge to further interact with the tank. Sewage mixing reaction.

3. By setting the fixed block, the telescopic cylinder is rotatably connected with the fixed block. When the servo motor is in the off state, the telescopic cylinder will be in a vertical state under the action of gravity and will not occupy the space in the pool. It is relatively easy to clean the pool. convenient.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-3, a reaction tank for sewage treatment includes a tank body 1 and a servo motor 2, the servo motor 2 is arranged below the outside of the tank body 1, and the tank body 1 is coaxially provided with a vertically arranged rotating shaft 3 , the lower end of the rotating shaft 3 is arranged through the bottom surface of the pool body 1 and is fixedly connected with the output end of the servo motor 2. It should be noted that the rotating shaft 3 is connected to the lower side wall of the pool body 1 through the sealing bearing 10 in a sealed and rotating manner. The bearing 10 can not only ensure the sealing between the rotating shaft 3 and the pool body 1, but also make it rotate more smoothly.

In the present invention, a plurality of fixing blocks 4 are fixedly connected to the side wall of the rotating shaft 3 , and the other end of each fixing block 4 is rotatably connected with a telescopic cylinder 5 . The sliding cavity 6 is provided with a sliding rod 7. One end of the sliding rod 7 close to the fixed block 4 is fixedly connected to the inner bottom surface of the sliding cavity 6 through a spring 8, and the other end of the sliding rod 7 extends to the outside of the sliding cavity 6. , not only the telescopic cylinder 5 itself can play a stirring role, but also the sliding rod 7 can play a stirring role in the radial direction, so that the stirring effect is better.

It is slidably connected to the side wall of the sliding cavity 6, and the limit block 11 can limit the position where the sliding rod 7 moves to prevent the sliding rod 7 from slipping. 9. It can further improve the stirring effect, so that the activated sludge can further mix and react with the sewage. It is worth mentioning that the upper end of the pool body 1 is provided with a hinged mesh cover 12, which can prevent external debris from falling into the pool body 1.
