Abstract
The utility model relates to a novel vacuum cleaning truck, which includes a truck body. A sewage tank and a cam pump are mounted on a chassis of the truck body, wherein an input end of the cam pump is connected with an engine of the truck by a drive mechanism; an outlet end of the cam pump is connected with the sewage tank by a sewage suction pipeline and a blow-down pipeline; and a globe valve is arranged between the blow-down pipeline and the sewage tank. The cam pump provided by the utility model utilizes the truck engine as the power source, which transmits power to the cam pump by mechanical drive to realize the control on the pump. The manual globe valve is closed during the sewage suction for a clockwise rotation of the pump so that sewage water enters the tank body from the top thereof, and the pump is shut down when the liquid level reaches an index value; during the blow-down, the globe valve is opened for a counterclockwise rotation of the pump, so that the sewage water is discharged from a blow-down pipe at the bottom of the tank body. An inclined installation of the sewage tank prevents the sewage water from accumulating in the tank body.
Description
Technical field
The utility model relates to a kind of suction-type sewer scavenger, the especially a kind of collection of foul water tank on the transport facilitys such as passenger steamer, long-distance bus, railway passenger train and novel evacuated suction-type sewer scavenger of discharging realized.
Background technology
At present domestic suction-type sewer scavenger manufacturer designs and the manufacturing suction-type sewer scavenger, and has formed tandem product all in accordance with People's Republic of China's automobile industry standard " suction-type sewer scavenger " QC/T652-2000 requirement.These products all have following common feature:
(1) drives vacuum suction device (vacuum pump) by automotive engine, in the sewage jar, form vacuum;
(2) operating process of suction-type sewer scavenger is as follows: vacuum pump is started working, form in the tank body vacuum → working medium be drawn into jar in → drain working medium → tank body and reset to a predetermined quality → stop vacuum suction device → open bonnet or the foul valve → lifting tank body reprinted
Can learn that by These characteristics it is propulsion source that traditional suction-type sewer scavenger has with the automotive engine, does not need the advantage of other power connection, but also deposit 1. in the operating sequence complexity simultaneously; 2. the device structure complexity wants to realize the lifting of tank body and reset, and complicated transmission device must be set, and realizes by hydraulic efficiency pressure system usually that at present equipment is provided with complicated hydraulic efficiency pressure system; 3. the device structure complexity causes maintenance comparatively complicated; 4. keep vacuum in the tank body during soil pick-up, the manufacture process requirement of tank body is higher, the manufacturing cost of raising; When 5. vacuum pump was worked, large quantity of exhaust gas was discharged, and can cause second environmental pollution; 6. sewage is by gravitational discharge, and pipeline is thick, and blowdown is consuming time more, and the obstruction accident easily takes place.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, cost is low, pollution-free, novel evacuated suction-type sewer scavenger that fault rate is low.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of novel evacuated suction-type sewer scavenger, comprise car body, the car body chassis is provided with sewage jar and cam pump, the cam pump input end is connected with automotive engine by driving device, the cam pump mouth is connected with the sewage jar by suction, blowoff line, is provided with ball valve between blowoff line and the sewage jar.
The top of one end of described sewage jar and bottom are respectively equipped with and suction, the suction of blowoff line bonded assembly, sewage draining exit; Sewage jar other end top is respectively equipped with air extractor vent and liquid level switch; Sewage jar one end that is provided with suction, sewage draining exit is lower than the other end.
Described driving device comprises belt wheel and power-transfer clutch, is connected by belt wheel between automotive engine output shaft and the cam pump input shaft, rotating speed is adjusted in the economical operation range of speed of cam pump, and power-transfer clutch is arranged between cam pump and the automotive engine.
Cam pump of the present utility model is a propulsion source with the automotive engine, by mechanical drive, gives cam pump with transmission of power, with the operation of control pump, during soil pick-up manual ball valve is closed, pump is just changeed, sewage enters tank body by the tank body top, when liquid level reaches predetermined value, stops pump operation.During blowdown, manual ball valve is opened, the cam pump counter-rotating, sewage is discharged by the blow-off pipe of tank base, and sewage is irritated and is tilted to install, and can not store sewage in the tank body.
The utlity model has following characteristics:
(1) adopts rotary lobe pump, realize the collection and the discharging of sewage by the hand of rotation that changes pump.
(2) only in the soil pick-up pipeline, form vacuum (maximum-80KPa), and keep atmospheric pressure state in the tank body.
(3) dirt sucking tube and blow-off pipe are shared, only need to change the hand of rotation of pump, can form the operation of suction-type sewer scavenger suction sewage, have simplified workflow;
(4) during blowdown, tank body by the counter-rotating of pump, can form blowdown without lifting, therefore can save complicated hydraulic gear, has simplified device structure, has reduced maintenance cost;
(5) do not need tank body is vacuumized, reduced exhaust emission;
(6) no longer adopt the gravity blowdown, reduced the occurrence probability of plugging fault
