Vacuum storage tank type defecation discharge system for high speed train

Abstract

The invention discloses a vacuum tank high-speed train excreta disposal system. It includes excrement collector mechanical components assembly, control executive valve components, dirt bin and controller. The excrement collector mechanical components assembly consists of urinal, washing ring, small water chamber and vacuum generator; the control executive valve components consist of one two-position four-way valve, one two-position three-way valve, two two-position two-way valves, one air-operated blow-off valve, two magnetic valves, three ball valves and a dirt bin antifreeze electric heating blanket power switch; the dirt bin is equipped with heat-insulating layer on the outer surface and anti-wave plate on the inner surface, the bin interlayer is equipped with antifreeze electric heating blanket; two pairs of controller are cold duplicate controller each other and consist of input, output and MCU module, it is the control central of whole system. The vacuum tank high-speed train excreta disposal system eliminates the pollution of train direct disposal washing rooms to the train route environment, solves the corrosion of dirt to the train running components and the problems of dirt is harm at the physical and mental health of passengers and railway maintenance staff.

Description

technical field [0001] The invention relates to a high-speed train excrement discharge system, in particular to a vacuum storage tank type high-speed train excrement discharge system. Background technique [0002] As the speed of railway passenger cars continues to increase, the disadvantages of in-line toilets are becoming more and more prominent: polluting the environment along the railway line, corroding train running parts, and endangering the health of passengers and railway maintenance personnel. For this reason, the Science and Technology Department of the Ministry of Railways has carried out a special study on the pollution of trains by straight-row toilets: when the train speed is 100Km / h, the detection rate of coliform bacteria in the train compartments of straight-row toilets is over 60%, while the detection rate of coliform bacteria in train compartments of closed toilets The yield rate is only 1.6%; further research shows that the large intestine of the closed t...
