Example Embodiment

[0033] In order to better explain the present invention and facilitate understanding, the following describes the present invention in detail through specific embodiments in conjunction with the accompanying drawings.

[0034] The invention provides a dry vacuum pump sewage suction truck.

[0035] Such as Figure 1-Figure 6 As shown, the present invention includes a car body 1, a working tank body 2, a sewage suction pipe 4, an air suction pipe 6, a sewage pipe 8, a vacuum system and a power system.

[0036] In the embodiment of the present invention, the vehicle body 1 includes a flat plate or a flat frame structure that carries the working tank 2 or other components and is supported by the vehicle chassis. The working tank 2 occupies most of the area of ​​the plane plate or plane frame structure. In addition, due to the use of dry vacuum pumps, the vacuum system and power system are small in size, which can expand the effective carrying space of the car body. In addition, the sm...

Abstract

The invention relates to an environmental sanitation working vehicle, in particular to a dry vacuum pump sewage suction truck. The dry vacuum pump sewage suction truck comprise a vehicle body, a working tank, a suction pipe, a sewage pipe, a vacuuming system and a power system. The working tank body is arranged on the vehicle body and is respectively communicated with the sewage suction pipeline and the sewage discharge pipeline. The vacuum pumping system comprises a dry vacuum pump, and a four-way valve is arranged between the dry vacuum pump and the air extraction pipeline. The working gas path in the vacuum pumping system is changed so that the working tank body is vacuum pumped and the normal pressure is restored, thereby realizing the sewage suction and discharge work of the sewage suction vehicle. The power system includes the engine, transmission, power takeoff and retarder, which power the dry vacuum pump. The dry vacuum pump dirt suction working truck of the invention does notneed to be equipped with an oil-gas separator, omits the necessary accessories in the rotary vane pump and other air suction systems, simplifies the air suction system, and improves the adaptabilityof the dirt suction truck to the complex air suction environment.

Description

technical field [0001] The invention relates to the field of sanitation work vehicles, in particular to a dry vacuum pump sewage suction truck. Background technique [0002] With the acceleration of urbanization and industrialization in our country, the daily domestic and industrial sewage and sewage in cities and towns are also increasing day by day. Due to the insufficient sewage discharge capacity of urban sewers, sewer blockages often occur, which seriously affects people's daily life. . [0003] The sewage suction truck is a municipal sanitation vehicle used to collect, transfer, clean up and transport sludge or sewage to avoid secondary pollution. It is not only self-priming and self-discharging, but also has fast working speed, large capacity and convenient transportation. At present, the sewage suction truck adopts a vacuum pump, which has a large suction force and a long suction distance. It is especially suitable for the suction, shipment and discharge of sediment...
