Abstract

The invention provides a railway train excrements collection system comprising a urinal and a soil box. The system is also provided with a vacuum pumping device of the soil box. The system is further provided with a water pressure intensifier and a flushing valve, wherein the flushing valve is an air-controlled two-position three-way directional control valve, and the flushing valve is connected with the water pressure intensifier, the flooding nozzle of the urinal and a water supply respectively. The system is also provided with the flushing valve controlled by a first electromagnetic directional valve and the compressed air supply circuit of the water pressure intensifier. The system is provided with a dejection valve arranged between the urinal and the soil box, and a working cylinder cavity for driving the valve plate of the dejection valve is arranged in the dejection valve. The system is provided with the compressed air supply circuit of the working cylinder controlled by a second electromagnetic directional valve. The system is provided with an air inlet pipeline which connects a train compressed air source and the first electromagnetic valve and the second electromagnetic valve. The system of the invention which can be actuated pneumatically by the train air supply system with a simple structure and reliable performance is applicable to trains.

Description

Technical field [0001] The invention relates to the field of railway train excrement collection systems. Background technique [0002] As the country's requirements for environmental protection and sanitation of railway passenger trains become higher and higher, the direct excrement method of passenger trains will gradually be banned in the past. At present, the railway train excrement collection system has a complicated structure and high cost, which is not conducive to popularization and promotion on railway trains. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a railway train excrement collection system suitable for use and promotion on trains. To this end, the present invention adopts the following technical solutions: it includes a toilet and a dirt tank, the system is also provided with a vacuum device for the dirt tank; the system is also provided with a water booster, a flush valve, and the flush valve It is a...
