Abstract

The utility model relates to a vacuum pumping apparatus, which is composed of a vacuum liquid barrel, a sewage tank, a vacuum pipeline, and a liquid circulating vacuum pump, wherein, the vacuum liquid barrel is connected with the liquid circulating vacuum pump by a pipeline, the liquid circulating vacuum pump is connected with the sewage tank through the vacuum pipeline, and sewage tank is connected with a sewage collecting pipeline; sewage and depositing garbage can be pumped in the sewage tank by using the vacuum pressure difference, as the opening of the vacuum pipeline is arranged at the highest place in the sewage tank, and the sewage and dirt only enters the sewage tank; the depositing blocking phenomenon caused by that the sewage and the dirt of a free flow type sewage truck can not be discharged thoroughly can be changed, the sewage and dirt discharging property is improved, and the sewage and dirt discharging time is reduced.

Description

A kind of gulley emptier vacuum suction apparatus
The utility model relates to a kind of vacuum suction apparatus, especially a kind of vacuum suction apparatus that is installed on the Mobile Decontamination Vehicle.
In the ground service vehicle of civil aviation, existing gulley emptier all is gravity, and the mode of discharging aircraft sewage only relies on the gravity drop, therefore can produce alluvial inevitably, and dirt can't obtain removing for a full due, and serious also can produce obstruction.The seat in the plane of some blimps is lower, carries out the blowdown operation with traditional gravity gulley emptier and more is prone to above-mentioned consequence.And the fecal suction truck that a kind of environmental sanitation department uses is to use the centrifugal pump directly suction and the mode of carrying the gulley emptier dirt.Because of sewage dirt directly passes through the pump housing, shorten the service life of centrifugal pump greatly, also bring the shortcoming of pump housing self seal difference simultaneously.
The purpose of this utility model is to provide a kind of gulley emptier vacuum suction apparatus that can overcome above-mentioned shortcoming in the prior art, this installs the mode of arranging and directly aspirating conveying on the sewage vehicle with gravity in the alternative prior art of the mode of vacuum draw certainly, can solve the problem that traditional gravity gulley emptier blowdown is not smooth, be easy to generate alluvial and result in blockage, and the problem that solves the easy water clock of the direct drawing-in type sewage dirt of environmental sanitation vehicles.
The utility model is achieved in that a kind of vacuum suction apparatus of the utility model, by the vacuum fluid cylinder, foul water tank, liquid-ring vacuum pump in vacuum pipe and the prior art constitutes, wherein, the vacuum fluid cylinder provides cooling and sealing water by pipeline for liquid-ring vacuum pump, liquid-ring vacuum pump is connected with foul water tank by vacuum pipe, the most significant bit of vacuum pipe opening in foul water tank, make and form vacuum in the fully enclosed foul water tank, utilize the vacuum pressure difference that sewage and deposition rubbish are sucked in the foul water tank by collecting tube, because the most significant bit of vacuum pipe opening in foul water tank, so sewage dirt only enters in the foul water tank, and can not pass through and enter vacuum pick-up system.
The utility model is because adopted the technical scheme of above-mentioned vacuum draw, discharge endless, produce the alluvial phenomenon of blocking so can change gravity gulley emptier sewage dirt, thereby reach totally filth-discharging effect completely, increased blowdown usefulness, reduced blowing time.Several dirt sucking tubes are aspirated simultaneously structurally become possibility, that is to say the sewage that can absorb several foul water tank on the aircraft simultaneously, changed the operational method that the gravitational discharge mode once can only receive the sewage of a foul water tank, the time of blowdown operation shortens dramatically, also can overcome the weeping once more that the environmental sanitation fecal suction truck exists, blowdown is thorough, and dirt rubbish can be not left, reached the purpose of this utility model.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the scheme drawing of a kind of vacuum suction apparatus of the utility model.
As shown in Figure 1, a kind of vacuum suction apparatus of the utility model, by vacuum fluid cylinder 1, foul water tank 2, liquid-ring vacuum pump 4 in vacuum pipe 3 and the prior art constitutes, wherein, vacuum fluid cylinder 1 provides cooling and sealing water by pipeline for liquid-ring vacuum pump 4, liquid-ring vacuum pump 4 is connected with foul water tank 2 by vacuum pipe 3, the most significant bit of vacuum pipe 3 openings in foul water tank 2, make and form vacuum in the fully enclosed foul water tank 2, utilize the vacuum pressure difference that sewage and deposition rubbish are sucked in the foul water tank 2 by collecting tube, because the most significant bit of vacuum pipe 3 openings foul water tank 2 in,, and can not pass through and enter vacuum pick-up system so sewage dirt only enters in the foul water tank 2.In illustrated embodiment, vacuum fluid cylinder 1 is connected with liquid-ring vacuum pump 4 with vacuum liquid return water pipe 6 by vacuum liquid coolant inlet pipe 5, and for liquid-ring vacuum pump 4 provides cooling and sealing water, under power driven, the water of cleaning forms pendular ring in liquid-ring vacuum pump 4; Foul water tank 2 casings are hermetically sealed, be connected with the collecting tube that has gate valve, vacuum pipe 3 is connected liquid-ring vacuum pump 4 with foul water tank 2, the most significant bit of vacuum pipe 3 openings in foul water tank 2, liquid-ring vacuum pump 4 running backs form the degree of vacuum (negative pressure that is roughly equal to 0.033 megapascal (MPa)) of 254 mm Hg in foul water tank 2.Because the most significant bit of vacuum pipe 3 openings in foul water tank 2, sewage dirt only is pumped in the foul water tank 2, and can not enter vacuum system.In a whole set of vacuum line, devices such as safety valve 7, vacuum indicator 8, boiler check valve and filter screen can also be set, to guarantee the safety of system.In foul water tank 2, can also be provided with the oilysewage surface height warning interlock system in the prior art, both guarantee the high efficiency of operation, guarantee the safe and reliable of work again.Can also in foul water tank 2, set up the cleaning spraying device in the cover prior art, but the automated washing foul water tank makes also improve the service life of foul water tank.
