Vacuum decontamination vehicle

Abstract

The invention discloses a vacuum decontamination car, belonging to the field of environmental health equipment, which comprises a car, a tank on the car, a sewage outlet arranged at the bottom of the tank, and a drain pipe communicated with the sewage outlet. The vacuum decontamination car is characterized in that a closed negative pressure room is arranged in the tank; a vacuum pump is arranged on the tank; the air entry of the vacuum pump is communicated with the negative pressure room; a sewage entry is arranged on the negative pressure room and communicated with a delivery pipe; the otherend of the delivery pipe is connected with a spiral conveyer; a emptying door is arranged at the bottom of the negative pressure room; a solid-liquid separating grid is arranged horizontally in the tank under the negative pressure room, and a sewage storing room is formed under the solid-liquid separating grid. The vacuum decontamination car has the advantages of high pollutant suction, separation between solid and liquid, high decontamination efficiency, wide use in inspection well and septic tank compared with the prior art.

Description

technical field [0001] The invention belongs to the field of environmental sanitation equipment, and in particular relates to a vacuum cleaning vehicle. Background technique [0002] The underground drainage channels in cities are equipped with inspection wells, where dirt is easy to accumulate, making the underground drainage channel crossings smaller or blocked, and water is easy to accumulate on the road surface, so the inspection wells need to be dredged frequently. The existing common method is to manually use traditional tools such as shovels and ladles to carry out cleaning operations, place the cleaned dirt on the road, and then load it into a transport vehicle, which has low operating efficiency and high labor intensity. And other problems, and caused secondary pollution to the environment. Patent No.: 02240927.0 discloses a diesel engine, culvert type multifunctional vacuum suction tank, which includes a tank body, the tank body is provided with a suction port at ...

Problems solved by technology

However, the suction of this kind of sewage suction tank is small, and it can only absorb relatively thin sludge, but cannot remove thicker sludge, and the sludge and sewage in the sewage suction tank are mixed together, and the sewage cannot be discharged separately, which reduces the efficiency of the sewage suction tank. quality factor
