Environmental protection toilets for trains

Abstract

The invention discloses an environment protection toilet for a train, which includes a toilet, a touching switch, a flushing tank, a temporary storage tank, a storage tank and a controller, wherein, the toilet is connected with the inferior temporary storage tank via a pipeline. A switch is arranged on the joint between the temporary storage tank and the pipeline, and a storage tank is positioned under the temporary storage tank, wherein, the storage tank is connected with the temporary storage tank via the pipeline, and a switch is arranged on the joint of the temporary storage tank and the pipeline; a storage bag and an air bag are arranged inside the storage tank, one end of the air bag is connected with pressure system of the train. The storage tank is also provided with a microwave generator. The microwave generator heats and evaporates the moisture in the feces and the moisture enters a condenser via a condensing tube arranged on the storage tank to be cooled. The cooled moisture is collected in a header tank. The cooled water in the header tank is sent to the flushing tank via a pump arranged in the header tank. The bottom of the storage tank is further provided a weighing device. Therefore, the environment protection toilet has the advantages of integrating feces collection and treatment, thus reducing secondary pollution of the feces.

Description

technical field [0001] The invention relates to a non-excrement discharge and high-efficiency treatment device installed on a passenger train, in particular to a train environmental protection toilet. Background technique [0002] Along with the development of the national economy and the raising of people's living standards, more and more people take the train. People take the train to eat, drink, and defecate. However, the defecation problem has not been solved until now. Usually, when the train stops at the station, the conductor locks the toilet door in advance to prevent passengers from going to the toilet. If the toilet is not locked, the passenger goes to the toilet, and the excrement is discharged on the platform, polluting the environment. At present, train toilets are mainly in-line toilets and storage toilets. In-line toilets discharge feces directly outside the train and cause environmental pollution, and they will be eliminated soon. The storage type toilet use...

Problems solved by technology

[0002] With the development of the national economy and the improvement of people's living standards, more and more people take the train. People take the train to eat, drink, and defecate. However, the problem of defecation has not been solved until now.

Usually, when the train stops at the station, the conductor locks the toilet door in advance to prevent passengers from going to the toilet. If the toilet is not locked, the passengers go to the toilet, and the feces are discharged on the platform, polluting the environment

At present, train toilets are mainly in-line toilets and storage toilets. In-line toilets discharge feces directly outside the train and cause environmental pollution, and they will be phased out soon.

Storage toilets use a storage to store feces on the train, and use a car to suck and unload them after arriving at the station, but because of the limited capacity, they cannot be stored for a long time

In reality, when there are too many people, the use of toilets will be restricted, and even cause secondary pollution

[0003] There are a lot of researches on train toilet technology both at home and abroad. According to the treatment stage, it can be divided into two categories: the first type of technology: train feces collection and treatment phase separation, the typical situation is: the train is equipped with a toilet, and the ground is built. Treatment station, most of the train toilets at home and abroad adopt this technology, which costs a lot of money, the system process is complicated, and it is not easy to operate. The second type of technology: it is divided into incineration method and biological method (ecological method). The incineration method is to directly incinerate the sewage , so that the volume of the residue after incineration is 1 / 1000 of the volume of the original dirt to facilitate storage on the train, but the residue cannot be reused

The biological method is pollution-free, and the collection and treatment of feces are integrated. Although high-quality and efficient manure can be obtained, it is greatly affected by environmental factors, and the system takes a long time to process and has a large volume.

The current sewage treatment device for train toilets requires huge costs for the construction of ground equipment, and the labor cost of the sewage extraction operation is also high. The sewage extraction operation itself is a typical dirty, tiring, and dangerous operation.
