Container type vertical sheet sewage filtering device

Abstract

The invention discloses a container type vertical sheet sewage filtering device. The filtering device comprises a base and a container type filtering box body arranged on the base; the container typefiltering box body comprises a sewage filtering tank, a clean water tank and an equipment room; the sewage filtering tank comprises a tank body, and a vertical sheet filtering system, a backwashing system / bottom mud suction system, a traction walking system and a driving system which are connected in sequence; an electric control cabinet, a centrifugal pump, an electric valve and a water outlet pipeline are arranged in the equipment room; the centrifugal pump is connected with the backwashing system / bottom mud suction system through an electric valve; a speed reducing motor is arranged in thedriving system, and the backwashing system and the bottom mud suction system are driven to work through the traction walking system. The device is simple in structure and small in pool body size, andthe problems that transportation is inconvenient, the transportation cost is high, the structure in the way is prone to deformation, and the on-site assembling and welding difficulty is large are thoroughly solved; the tank wall of the tank body is made of a corrugated steel plate made of a weather-proof material, is not easy to deform and can meet structural mechanical property requirements, a mechanical reinforcing structure is not needed, and the structural weight is light and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a sewage filtering device, in particular to a container-type vertical piece sewage filtering device. Background technique [0002] With the development of the economy, people's living environment has been destroyed. As a result, the attention of environmental protection and governance has gradually increased. The demand for domestic sewage and river sewage treatment is increasing day by day. The establishment of large sewage treatment plants not only needs to occupy a large area of ​​land, Supporting a large-scale urban pipe network also requires a large number of operation and maintenance personnel, and the investment cost is huge. Due to the large gap in economic development between regions, especially for economically poor areas, it is too difficult to establish a fixed sewage plant. Moreover, the current fixed sewage treatment plants can only be used to treat domestic ...

AI Technical Summary

Problems solved by technology

[0003] The movable sewage filter devices that have appeared on the market currently have the following defects: 1) The pool body of the filter device is too large, and the width and height dimensions exceed the width and height limit requirements of cargo transportation and traffic control (2438×2896mm), Therefore, it is necessary to disassemble the pool body in the factory, and then assemble and weld it after transporting to the site. Not only the transportation cost is high, but also many pool body plates are easily deformed during transportation, which increases the difficulty of on-site assembly and welding.

This kind of pool structure is heavy and costly

[0004] That is to say, although a movable sewage filter device has appeared on the market, the structure of the pool is large, and the width and height exceed the relevant requirements for cargo transportation. The transportation is inconvenient, and the pool wall is thick and low in strength. The pond body is bulky, the production cost and transportation cost are high, and the degree of intensification is low.
