Abstract
The invention relates to a vacuum-operated toilet comprising a WC bowl, a vacuum generator, a collection container, conduits containing valves and an intermediate container that is located between the WC bowl and the collection container and comprises an inlet valve and an outlet valve. The respective housings of the inlet valve (11) and the outlet valve (12) are connected to a pressure source.
Description
The present invention relates to a kind of vacuum toilet, the pipeline and one that it comprises a toilet pond, a vacuum generator, a collection container, have a valve is arranged on the intermediate receptacle between toilet pond and the collection container, described intermediate receptacle has one and enters a valve and a blow off valve, and relates to a kind of method of operating such vacuum toilet.
The operational example of a kind of described vacuum toilet device and such device is as being described among DE37 28 157 A1.The equipment that the special plan of disclosed there device is used to move, for example train and motor bus.Wherein, the device of being introduced there comprises following ingredient: the pipeline and that a toilet pond, is used for vacuum device, a collection container, have a valve is arranged on the intermediate receptacle between toilet pond and the collection container.
In said method, operating process is as follows: by being used for vacuum device, produce a negative pressure in intermediate receptacle, described to be used for vacuum device can be one to be connected in the ejector of a compressed air container.In the front and back of intermediate receptacle a valve is set respectively, they can pneumatically be opened.After handling a push button, generation one negative pressure and flushing water enter into the toilet pond in intermediate receptacle.When opening the valve that is arranged on the intermediate receptacle front, because pressure differential is arranged, the toilet pond under being in atmospheric pressure is drawn into the intermediate receptacle with flushing water and ight soil.Then, intermediate receptacle is placed under the superpressure when shut off valve, and after opening the valve that is connected in the intermediate receptacle downstream, the inclusion of intermediate receptacle is discharged in the collection container.When setting up pressure in intermediate receptacle, sewage also mediates in the container and also is pressed in the valve housing when the seal leakage that enters valve and blow off valve or when grinding away, and this may cause depositing and may causing the inefficacy of valve after certain period.This thing happens for possibility in addition, that is, when opening one of them valve, the while is the open shells space in short-term, and sewage just enters into housing.
The present invention is intended to stop sewage to invade in the valve chest in this wise, this realizes by following manner in the vacuum toilet of described pattern at a first brush, promptly, enter valve with discharge valve housing respectively with one or separately a pressure medium source be connected, and be used for when collection container is carried the pressure of effluent when setting up in intermediate receptacle, the pressure in the housing is higher than the pressure in the intermediate receptacle.
Pressure medium source also can be connected in the side away from intermediate receptacle of valve.
The invention still further relates to a kind of method of operating vacuum toilet, the pipeline and one that described vacuum toilet comprises a toilet pond, a vacuum generator, a collection container, have a valve is arranged on the intermediate receptacle between toilet pond and the collection container, described intermediate receptacle has one and enters a valve and a blow off valve, wherein, when in intermediate receptacle, setting up pressure, enter valve chest and blow off valve housing and remain on than under the higher pressure of the pressure of intermediate receptacle.
Obviously, utilize design of the present invention, can be implemented in and do not form deposition in the valve chest, this will improve the application life of valve.
Below illustrate the present invention by accompanying drawing.
A unique accompanying drawing is expressed a part according to vacuum toilet of the present invention.
With 10 mark intermediate receptacles, it presses flow direction between a toilet pond 19 and a sewage conduct or a collection container 20 among the figure.This intermediate receptacle 10 is closed by valve in both sides, specifically, is by means of entering valve 11 and blow off valve 12.Here can be guiding valve or flexible pipe valve (Schlauchventil).
Shown in the figure, two valves 11 are connected with a compressed air piping with 12 housing, and, by additional P
gWhat represent is, applies a pressure higher than the pressure in the intermediate receptacle here, if set up the words of the pressure that is used to carry effluent in intermediate receptacle.
Therefore, when in intermediate receptacle, setting up pressure P, compressed air P is provided for simultaneously the housing of valve 11 and 12
g, then enter into intermediate receptacle 10 from each valve via these " cleaning " compressed air, thereby, can not gather effluent there, and each valve keeps " cleaning " and final application life of improving valve and whole system.
In a kind of preferred form of implementation of the present invention, also can draw needed pressure P by the pressure P that in intermediate receptacle, works
