Follow-up sewage tank with membrane sealing cover

Abstract

The invention discloses a follow-up capping and film-sealing cover for a sewage pool, which adopts the structure that a column is vertically arranged at the bottom of the cover and is usually fixed in the sewage pool; a pipeline support frame is fixed on the column and extends outwards around the column in a radiative manner; a ring-shaped steel rail is arranged on the edge of the pipeline support frame and supports supporting wheels; vertical plane films supported by an outer steel ring are arranged at the upper parts of the supporting wheels along the ring-shaped steel rail and positioned in the outer steel ring in a supported manner; observation windows are formed on the vertical plane films at intervals; an extraction pipe is supported at the upper part of the outer steel ring; an inner steel ring is fixed above the column in a rotatable manner; and reverse cords are fixed on the inner steel ring and the outer steel ring, so are bearing cords. According to the invention, the follow-up capping and film-sealing cover can realize capping and sealing for big size pool bodies, is light in weight, convenient to operate, and can prolong the service life of the equipment.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to sealing treatment equipment for treating waste gas produced in sewage pools. Background technique [0002] With the rapid development of my country's economy and the continuous expansion of urban scale, the living environment of the people is also deteriorating day by day. Serious pollution, such as pharmaceutical and chemical industry, paper industry and municipal sewage treatment plants, are getting closer and closer to the urban area. While people's requirements and voices for a healthy environment are getting higher and higher, the government attaches great importance to the treatment of waste gas and sewage caused by related industrial production, and is gradually introducing relevant policies. [0003] At present, there are many residential buildings built around many sewage plants. The factory pools for centralized sewage treatment were originally exposed outside. Once...

Problems solved by technology

However, this kind of structure belongs to the fixed cover body, and the walking equipment cannot be exposed outside the cover body. In this way, the operation and maintenance personnel need to enter the sealing cover body to operate, which will be very dangerous due to the influence of toxic waste odor, and the walking sewage treatment Due to the erosion of corrosive waste odor in the sealing cover body, the equipment and testing equipment are very prone to failure, and the service life is greatly shortened
