Description

Long-span sewage treatment sedimentation tank

technical field

The utility model relates to the technical field of sewage treatment equipment, in particular to the technical field of refined cotton sewage treatment equipment.

Background technique

The raw material required for the production of refined cotton is cotton linters, whose main chemical components are cellulose, lignin and hemicellulose, which are non-toxic, tasteless, and easy to absorb water. It is widely used in food, medicine, daily chemicals, plastics, electronics, papermaking, metallurgy, aerospace and many other fields. During the rolling and rinsing process of refined cotton production, a large amount of reducing industrial sewage will be produced. In the process of sewage treatment, the sewage treatment sedimentation tank is one of the important equipment, but the current sewage treatment sedimentation tank has the following deficiencies in use Advantages: First, the volume is small, the volume of sewage treatment is limited, and the work efficiency is low; second, the sludge deposited at the bottom of the pool is troublesome to clean up, which often seriously affects the efficiency and effect of sewage treatment.

Utility model content

The purpose of this utility model is to solve the low working efficiency of the sewage treatment sedimentation tank at the present stage, and the sludge is difficult to be quickly removed, and the proposed large-span sewage treatment sedimentation tank has a reasonable structural design and a high degree of automation.

In order to achieve the above object, the utility model adopts the following technical solutions:

The large-span sewage treatment sedimentation tank includes a large frame, a support column, an annular filter, a motor, a scraper, a sludge discharge pump, a water pump, a horizontal bar, a vertical bar and a pool body. The two sides of the big frame are respectively There are rollers, the motor is fixedly installed on the large frame and connected with the roller transmission, the bottom of the large frame is also provided with a rotating shaft, the large frame is movably installed on the upper end of the supporting column through the rotating shaft, and the lower end of the supporting column is fixed At the bottom of the center of the pool body, the supporting column is hollow, and a water outlet is opened on the supporting column, and an annular filter is placed on the outlet of the supporting column, and the annular filter is suspended on the large frame. The horizontal bar is fixed on the lower side of the large frame through the vertical bar. The bottom of the pool body is conical, and the horizontal bar is parallel to the bottom of the pool body. There is a sludge outlet at the bottom of the body, and the sludge discharge pump is connected with the sludge outlet through a pipeline. A water inlet is provided on the support column, and a water pump is provided at the water inlet. There is a clear water overflow port.

As a preferred solution of the present utility model, each of the trowels is inclined downward in a consistent manner.

The beneficial effects of the utility model are:

1. Reasonable and simple structural design;

2. Since there is a scraper in the sedimentation tank, the motor can drive the rollers to rotate, thereby driving the large frame to rotate. Under the action of the large frame, the scraper can be driven to work, and then the scraped sludge can be discharged Under the action of the sludge pump, it is easily discharged, and the work efficiency is high;

3. Since the water inlet and outlet are arranged at both ends of the support column, this is more conducive to the work of the large-span sewage treatment sedimentation tank, and the sewage treatment effect is good.
