Environment-friendly train toilet

Abstract

The invention discloses an environment-friendly train toilet, comprising a toilet bowl, a touch switch, a flushing tank, a pending tank, a storage tank and a controller; the toilet bowl is connected with the pending tank below the toilet bowl through a pipeline; the connection of the pipeline with the pending tank is provided with a switch; the storage tank is arranged below the pending tank; thestorage tank is connected with the pending tank through a pipeline, and the connection of the pending tank with the pipeline is provided with a switch; a storage bag and an inflatable bag are arrangedin the storage tank; one end of the inflatable bag is connected with a pressure system of a train; the storage tank is also provided with a microwave generator; the microwave generator heats and evaporates water in excrement; vapor enters a condenser and cools through a condensing pipe mounted on the storage tank; the cooled water is collected in a water collection tank; a water pump arranged inthe collection tank conveys condensate in the water collection tank into the flushing tank; a weigher is also mounted at the bottom of the storage tank. Therefore, the environment-friendly train toilet integrates excrement collection and treatment so that secondary contamination by excrement is lessened.

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.
