Sewage contamination vacuum exhaust and separation device

Abstract

The invention discloses a sewage contamination vacuum exhaust and separation device, which comprises a main tank body, a solid-liquid separation tank, a sewage suction port and a vacuum pump, wherein the vacuum pump is positioned at the tail part of the main tank body; the front end of the solid-liquid separation tank is provided with a sealing cover; the vacuum pump is connected with a power machine, an oil-gas separator and a four-way valve in a matching mode and is used for providing positive and negative pressure for the main tank body; the four-way valve is connected with the main tank body through a vacuum pipeline; the solid-liquid separation tank is horizontally arranged on one side of the top of the main tank body through a bracket; the sewage suction port is connected with the tail part of the solid-liquid separation tank through a first pipeline; the bottom of the front end of the solid-liquid separation tank is connected with the main tank body through a second pipeline; a round hole is formed in an inner wall of the solid-liquid separation tank; the tail part of the solid-liquid separation tank is provided with a cylinder; an air inlet and an air outlet on the cylinder are connected with the vacuum pump; a piston rod on the cylinder stretches into the solid-liquid separation tank; and one end of the piston rod stretching into the solid-liquid separation tank is provided with a push plate which is matched with an inner cavity of the solid-liquid separation tank. The sewage contamination vacuum exhaust and separation device is simple in structure, diversified in functions and convenient to use.

Description

technical field [0001] The invention relates to a sewage suction truck, in particular to a vacuum pumping and separating device for sewage and dirt. Background technique [0002] The sewage suction truck is a new type of sanitation vehicle that cleans, collects, and transfers sludge and sewage to avoid secondary pollution. The sewage suction truck can be self-priming and self-discharging, with fast working speed, large capacity, and convenient transportation. It is suitable for collecting and transporting feces and mud , crude oil and other liquid substances. At present, the domestic sewage suction truck generally adopts the vacuum pump of the sewage suction truck, which has a large suction force and a long suction distance. It is especially suitable for suction, shipment and discharge of sediment in the sewer, especially for sewer mud, silt, stones, and bricks. and other larger objects. But, after the vacuum sewage suction truck in the prior art works for a period of time...
