Description
Technical field
The present invention relates to passenger train toilet technical field, particularly relate to a kind of Vacuum excrement collection device for passenger train be applied in passenger train sanitary accomodation.
Background technology
Vacuum excrement collector in current passenger train sanitary accomodation generally adopts vacuum freeze mode, online or plug-type etc.Vacuum freeze mode dirt box keeps vacuum always, and set up vacuum compression air consumption large, noise is larger at every turn; It is fast that online pipeline sets up vacuum requirement speed at every turn, and therefore require that compressed air require is large, noise is larger; Generally plug-type malleation and the negative pressure of requiring is to control the discharge of dirt, and control system is complicated.
Summary of the invention
Object of the present invention be exactly in order to solve prior art exist the problems referred to above and deficiency; A kind of Vacuum excrement collection device for passenger train is provided; Have structure simple, use reliable, by being provided with vacuum middle transition case, more existing vacuum excrement collector saves pressurized air, reduces noise.
To achieve these goals, the present invention adopts following technical scheme:
A kind of Vacuum excrement collection device for passenger train, mainly comprise vacuum closet, vacuum middle transition case, dirt terminal collecting box, vacuum generating device, PLC, described vacuum closet is connected by the pipeline being provided with venting control valve with vacuum middle transition case, be connected by transfer conduit between vacuum middle transition case with dirt terminal collecting box, transfer conduit is provided with the first check valve, transmission control cock, transmission control cock is connected with vacuum middle transition case one end, dirt terminal collecting box is connected by the pipeline being provided with the second check valve with vacuum generating device, vac switch is connected with dirt terminal collecting box, dirt terminal collecting box is provided with level sensor II, venting control valve is provided with electromagnetic valve I, transmission control cock is provided with electromagnetic valve II, vacuum generating device is provided with electromagnetic valve III, PLC respectively with electromagnetic valve I, electromagnetic valve II, electromagnetic valve III, vac switch, level sensor II connects, transfer conduit is used for transmitting dirt and vacuum simultaneously, effective minimizing line clogging also plays cleaning effect to pipeline.PLC is connected with power supply.
Transfer conduit is provided with vacuum transmission control cock, and vacuum transmission control cock is in parallel with transmission control cock.
Vacuum middle transition case is provided with connection for bbreather pipe, level sensor I, and described connection for bbreather pipe, level sensor I are connected with PLC.When empty middle transition case liquid level of taking seriously arrives level sensor I specified altitude assignment, sensor I sends electric signal to PLC, control module control connection for bbreather pipe is opened, transmit control cock opens, and dirt is delivered to dirt terminal collecting box by vacuum middle transition case under the effect of difference of pressure.Terminal dirt box carries out vacuum to vacuum middle transition case and supplements.
Principle of work of the present invention: vacuum generating device extracts the air of whole system, produces and maintain certain degree of vacuum in terminal dirt box, middle transition case and pipeline.After the sewage of vacuum closet enters vacuum middle transition case under differential pressure action, the degree of vacuum of vacuum middle transition case reduces, and supplemented by the vacuum in terminal dirt box, the dirt in vacuum middle transition case enters terminal dirt box under differential pressure action.After terminal dirt box vacuum is reduced to certain numerical value, vacuum generating device work, for system re-establishes vacuum.When toilet stool washing, closet sends signal to PLC, and PLC controls the electromagnetic valve action on drain valve, and electromagnetic valve makes drain valve valve open, and after dirt enters vacuum intermediate box by suction function, drain valve cuts out; Electromagnetic valve action on PLC controls transfer valve, electromagnetic valve makes transmission control cock valve open, and dirt is sent to dirt terminal collecting box by suction function, and the interior vacuum of dirt terminal collecting box is supplemented vacuum middle transition case simultaneously.After in dirt terminal collecting box, degree of vacuum drops to certain numerical value, vac switch transmits signals to PLC, PLC controls the electromagnetic valve action on vacuum generating device, electromagnetic valve makes vacuum generating device start, vacuum is set up to system, after degree of vacuum rising reaches appointment numerical value, vac switch transmits signals to PLC, and PLC controls vacuum generating device and closes.When dirt terminal collecting box liquid level arrives level sensor II specified altitude assignment, sensor II sends electric signal to PLC, and control system forbids work.
Beneficial effect of the present invention:
1. structure of the present invention is simple, use is reliable, and by being provided with vacuum middle transition case, more existing vacuum excrement collector saves pressurized air, reduces noise.
2. transfer conduit is used for transmitting dirt and vacuum simultaneously, effectively reduces line clogging and also plays cleaning effect to pipeline.
3. transfer conduit is provided with vacuum transmission control cock, transmission control cock in parallel with vacuum transmission control cock, be applicable to vacuum middle transition case and dirt terminal collecting box distant time, guarantee reliability of service.
