Vacuum maintaining type feces-collection system with separator

Abstract

The invention relates to a vacuum maintaining type feces-collection system with a separator. The system comprises a toilet stool, a vacuum generator and a sewage box, wherein the toilet stool is connected with the sewage box through a connecting pipeline; the separator is arranged between the vacuum generator and the sewage box; the separator is connected with the vacuum generator through the connecting pipeline; a sewage box interface which is connected with the sewage box is arranged on the separator. The vacuum maintaining type feces-collection system has the beneficial effects that the vacuum generator in the feces-collection system provided by the invention can continuously generate vacuum even in a sewage draining process, the vacuum degree of the sewage box can be kept within a preset scope all the time, the feces-collection system can uninterruptedly work and more than two toilet stools can be simultaneously emptied; the separator can separate the sewage from air and the separating efficiency reaches up to 99%; the vacuum generator can be prevented from absorbing sewage in a running process, so that the problems that the vacuum generator cannot continuously work and the vacuum degree cannot be kept all the time in the emptying process of the toilet stool can be solved; the washing flow can be simultaneously executed, without waiting.

Description

technical field [0001] The invention relates to the field of vacuum holding type feces collection system, in particular to a vacuum holding type feces collection system with a separator. Background technique [0002] The toilet is an important facility in the toilet, and is widely used in airplanes, ships, trains, etc. Due to the constraints of technical means at that time, the earliest planes, ships, and trains were treated extensively in the form of straight rows, which not only affected the toilet environment, but also polluted the natural environment. Later, it developed into a professional toilet to collect feces, but it is not very ideal, either because of high maintenance costs, high failure rate, and space occupation. The vacuum closet toilet was developed later, and the negative pressure difference of the atmospheric pressure is used to suck the feces into the closet to enter the pipeline and finally reach the excrement storage tank. The advantage of the vacuum to...

AI Technical Summary

Problems solved by technology

This is because on a high-speed train, two toilets are generally installed on both sides of the aisle at the same time. Due to the limitation of the space at the bottom of the train and other conditions, it is impossible to install two sets of vacuum generators at the same time.

As mentioned above, when one toilet activates the flushing process, the other toilet has to wait for almost 1 minute to activate the flushing process, which greatly affects the convenience of passengers

[0006] Therefore, in the existing vacuum holding type feces collection system, its vacuum generator cannot continue to work during the sewage discharge, and the vacuum state cannot be maintained all the time in the dirt box, and the two closets cannot be emptied simultaneously, which brings inconvenience to passengers. great inconvenience

Even when only one toilet is installed, it takes a long time to use it again
