Example Embodiment

[0045] The following describes the embodiments of the present invention in conjunction with the drawings, but should not be limited to the following embodiments:

[0046] figure 1 It is a schematic diagram of the overall structure of the vacuum-maintained stool collection system of the present invention, according to figure 1 The working principle of this system is explained. The working principle of this system is: install the first sewage tank, the second sewage tank and the vacuum injection valve on the toilet sewage system; in the whole system operation, the vacuum injection valve guarantees the sewage tank and the sewage tank The pipeline connected to the toilet maintains a vacuum degree of -25KPA to -35KPA. When the toilet is working, the slide valve on the toilet and sewage tank pipeline opens, and the sewage and dirt in the toilet will be pumped into the sewage tank; system detection After the vacuum degree of the sewage tank is reduced, the vacuum injection valve will wor...

Abstract

The invention provides a vacuum holding type dejectas collecting system. The vacuum holding type dejectas collecting system comprises a first water tank, a second water tank, a third water tank, a fourth water tank, a squatting toilet, a sitting toilet, a grey water unit, a dining car water supply unit, a first sewage tank, a second sewage tank, a vacuum generator and a control unit, wherein sewage draining exits are formed in two ends of both the first sewage tank and the second sewage tank; washing water inlets are formed parallel to the sewage draining exits; and vacuum connections are arranged on the upper end surfaces of the first sewage tank and the second sewage tank so that the first sewage tank and the second sewage tank are connected with the vacuum generator. Due to the additionally arranged sewage tanks, the sewage and dirt are collected in the whole dejectas collecting system so that the dejectas collecting system has a very good protecting effect on the train operation surrounding environment and toilets of a train can be continuously used after arriving at stations. Due to the adoption of the vacuum holding type dejectas collecting system, the amount of water used to flush the toilets is greatly reduced so that water resources can be effectively saved and the flushing effect is improved.

Description

Technical field [0001] The invention relates to the field of water supply and drainage sanitation equipment for railway EMU vehicles, in particular to a vacuum-maintained stool collection system. Background technique [0002] Most of the drainage system pipelines of the toilets and wash basins of existing railway vehicles in my country are connected to the underside of the vehicle, and sewage and dirt are directly discharged outside the vehicle; it will cause serious pollution to the environment along the railway and a serious waste of water resources , And increase the cost of maintenance along the railway. In order to maintain environmental sanitation in the railway station, the railway department stipulates that the toilet will be closed after the train enters the station, and the toilet can only be opened again after the train leaves the station, which reduces the quality of service and brings inconvenience to passengers. [0003] The flush buttons and faucets of the toilets an...
