Description

A waste water treatment device

technical field

The invention relates to the field of mechanical equipment, in particular to a waste water treatment device.

Background technique

The role of wastewater treatment is to treat polluted water to meet the prescribed discharge standards. Wastewater treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical and health, catering and other fields. Important facilities for the environment, in the process of wastewater treatment, for wastewater containing solid substances, it is necessary to separate the solid substances in it, so as to facilitate the separate treatment of solid substances and wastewater.

Because the mechanical separation method has the best effect, mechanical separation equipment is the most widely used. Mechanical separation equipment can be divided into three types: screening, centrifugal separation and pressure filtration. The separation performance and separation efficiency of different types of separation equipment fluctuate greatly. It is found that the fluctuation range is between 10% and 70%. The reason for this phenomenon is that the filter holes are blocked due to the lack of maintenance after long-term use of the equipment, which not only affects the flow of wastewater, but also affects the effect of solid-liquid separation; in addition, there are also The problem is that the separation effect of the existing mechanical separation equipment is still unable to meet the separation requirements, and cannot achieve the predetermined clear liquid effect, which needs to be improved.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a wastewater treatment device with stable separation efficiency and high efficiency in view of the above problems.

In order to achieve the above purpose, a wastewater treatment device of the present invention includes an outer cylinder extending up and down, and its structural features are: a roller extending up and down is rotatably installed in the outer cylinder, and the top of the roller is provided with an inlet for connecting the waste water pipe. Sewage outlet, the top of the roller protrudes outward from the upper end of the outer cylinder, the outer wall of the roller is provided with a spiral blade, the spiral blade is close to the inner wall of the outer cylinder, the roller is provided with a sewage outlet that penetrates the wall of the outer cylinder, and the top of the outer cylinder is provided with a sewage outlet. There is a slag discharge hole, a clean water outlet pipe is installed on the lower side of the outer cylinder, a cleaning mechanism for dredging the sewage outlet is installed in the roller, and a roller motor for driving the rotation of the roller is installed on the outer cylinder.

When the equipment is working, the waste water or sludge is put into the roller through the sewage inlet. According to the needs, an appropriate amount of flocculant can be mixed into the waste water together, so that the solids in the waste water coagulate each other. The rotating roller during the working process forces the waste water in centrifugal force. Under the action of the sewage, it enters the outer cylinder through the sewage outlet, and then the spiral blades on the roller gradually lift the solid matter in the wastewater upward. During this process, the solid matter is gradually separated from the wastewater, and finally the solid matter is lifted to the top of the outer cylinder. , with the advancement of the subsequent solids, the solids at the top of the outer cylinder are compressed and dehydrated, and finally discharged from the slag discharge hole, and the purified water separated from the solids is discharged through the purified water outlet pipe. When the sewage outlet is blocked after the equipment has been running for a period of time, the cleaning mechanism can be used to clear the blockage to prevent the operation of the equipment from being blocked due to the blockage of the sewage outlet. Not only is the efficiency high, but also the separation is complete. The waste water is first separated from the solids under the action of gravity during the lifting process. When the solids reach the top of the outer cylinder, they are compressed and dehydrated. The dehydration rate is high, which is convenient for subsequent disposal of waste water and solid impurities. Work alone.
