Fully symmetrical cable-membrane anti-hanging structure synchronous rotary sealing system

Abstract

The invention discloses a holosymmetrical cable membrane reversed hanging structure synchronous rotation sealing system which comprises a sealing cover, a circular track beam formed by a first holosymmetrical flange connection rectangular truss module and a second holosymmetrical flange connection rectangular truss module in flanged connection, a universal adjustable bearing wheel device, a middle exhaust pipeline, and a holosymmetrical motive seal centre gas collection device connected to the circular track beam, wherein the sealing cover is fixedly connected with the circular track beam; the sealing cover and the circular track beam rotate together with a mud scraper traveling crane in a round tank synchronously; the holosymmetrical motive seal centre gas collection device comprises a seal joint and a seal joint connecting base; the connection between the seal joint and the seal joint connecting base is a rotation connected relation of a rotating shaft and a rotating hole; a motive seal structure of a bulge embedded groove is arranged between the seal joint and the seal joint connecting base. According to the holosymmetrical cable membrane reversed hanging structure synchronous rotation sealing system, the service life is long; the cost is low; the sealing work is reliable; the installation cost and the maintenance cost are low.

Description

technical field [0001] The invention relates to the technical field of deodorization equipment in sewage treatment plants, in particular to a technology of a fully symmetrical cable-membrane anti-hanging structure synchronously rotating circular pool body sealing system. Background technique [0002] In daily production activities, various forms of domestic sewage and industrial wastewater are produced every day. There are a large number of organic pollutants in these wastewaters. These sewages will produce a large amount of toxic and harmful gases during storage, transportation and biochemical treatment. Due to the large area of ​​the sewage treatment round pools used in sewage treatment plants containing mud scraping trucks, they are generally used open, so that the toxic and harmful gases produced are naturally released and pollute the surrounding environment. [0003] In order to eliminate the odor generated in the sewage treatment process, the traditional process curren...

AI Technical Summary

Problems solved by technology

[0004] The existing traditional sealing process has the following main disadvantages: (1) After the pool body is covered, the concentration of corrosive gases inside increases, and the internal steel structure is easily corroded; (2) The service life of the cover is short and the cost is high; (3) The circular tank body covers a large area, the seal cover is heavy, the original foundation needs to be reinforced, and the installation cost is high; (4) The circular tank body contains a mud scraper, and the seal cover covers the mud scraper inside to speed up (5) The equipment is inside the cover, and the concentration of harmful gas in the cover is high, which poses a safety hazard to the maintenance personnel entering the cover; (6) The sealing height of the fixed sealing cover is high , the internal volume is large, resulting in a large volume of corresponding supporting deodorization equipment, thick pipes, and increased costs
