FIELD OF INVENTION
This invention relates to an automatic bottle ejector system used with biological waste treatment system for railway passenger coaches.
PRIOR ART
As it is known, railway coaches were provided with direct fall toilet system wherein the human waste falls on the ground immediately upon being released, with the help of flushing water in the toilet pan.
The presence of human waste on the railway stations spoils the beauty of the atmosphere glimpse and air as well.
The above problem was solved by providing Controlled Discharge Toilet system to keep the railway stations clear of the human waste. It works on the principal of storing the human waste in a tank provided below the toilet of railway coaches and discharge the contents on attaining a particular speed so that it is discharged outside the railway premises. However, this causes environmental problems and air pollution.
The above problem was solved by providing a biological waste treatment system wherein untreated waste does not fall on the ground to spoil the railway track and railway stations. The human waste collected in the tank is consumed by bacteria and only treated water is discharged. The biological toilet systems are working satisfactory, but it sometimes get chocked as passengers throw bottles and other non-degradable articles in the pan. These articles get flushed with the water into the treatment tank. Therefore, it is cumbersome and time consuming to remove the bottles from the tank.
OBJECTS OF THE INVENTION
The primary object of the present invention is to provide an automatic bottle ejector system used with biological waste treatment system for railway passenger coaches, which is simple in construction.
Another object of the present invention is to provide an automatic bottle ejector system used with biological waste treatment system for railway passenger coaches, which is efficient.
Further object of the present invention is to provide an automatic bottle ejector system used with biological waste treatment system for railway passenger coaches, which overcomes disadvantages associated with the prior art.
Yet another object of the present invention is to provide an automatic bottle ejector system used with biological waste treatment system for railway passenger coaches, which prevents non-degradable articles such as bottles from entering into the tank.
Further object of the present invention is to provide an automatic bottle ejector system used with biological waste treatment system for railway passenger coaches, which facilitates removal of articles from chamber.
STATEMENT OF INVENTION
According to this invention, there is provided an automatic bottle ejector system used with biological waste treatment system for railway passenger coaches comprising of a chamber provided with a flapper valve and atleast two openings wherein one opening is connected to biological tank and other opening is in communication with a chute, and said chamber is disposed with an inclined cage for accommodating bottle.

DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS:
Toilet pan of railway passenger coach is connected to the system of the present invention through a flapper valve to discharge human waste, water, non degradable article etc.
The flapper valve opens in a chamber on its top surface of biological tank wherein the chamber is having two openings. One opening is connected to biological tank underneath and other opening opens in a vertical chute.
For details regarding the biological waste treatment system, reference may be made to 686/Del/2008 dt. 18.03.2008 in the name of Applicant.
An inclined cage is provided in the chamber which allows the human waste to enter the biological tank for further treatment and prevents bottles etc from entering into the tank. The bottle slides into the vertical chute provided on the side. A pneumatically operated door is provided as the opening of chute wherein the door is operated by means of an air cylinder. The door opens after predetermined count of flushes and ejects the bottle from the vertical chute.
Further, said vertical chute is provided with an inspection window, which is used to clean the chamber manually in case it is choked.
Reference may be made to fig. 1 wherein system of the present invention comprising of upper chamber which is attached with flapper valve and mounted over the biological tank. It has two openings, one opens in the tank and the other opens in the vertical chute. Thus, the chamber is connected to biological tank underneath and chute on one side.
Fig. 2 shows the assembly of bottle ejector depicting that there is inclined cage in the chamber and vertical chute has door which is operated by air cylinder.
Fig. 3 shows the ejection of bottle from flapper valve to the vertical chute and finally over the railway track by opening of the door.
Fig. 4 depicts the door and door opening mechanism i.e. fitment of air cylinder which operates after predetermined flushes for opening of door.
The flapper valve is connected to a logic controller as shown in the fig. 5. The logic controller controls the timing of water flow, sufficient enough to wash out the pan. Further, the controller controls rate of flow of water and opening/closure of the valve.
It is to be noted that the present invention is susceptible to modifications, adaptations and changes by those skilled in the art. Such variant embodiments employing the concepts and features of this invention are intended to be within the scope of the present invention, which is further set forth under the following claims:-
