Vacuum intermittent excrement collecting system for locomotive, working method thereof and locomotive toilet

Abstract

The invention belongs to the technical field of locomotive toilets, and discloses a vacuum intermittent excrement collecting system for locomotives, a working method of the vacuum intermittent excrement collecting system and a locomotive toilet, the vacuum intermittent excrement collecting system comprises a bedpan, a clear water tank capable of conveying flushing water to the bedpan, and a dirt tank used for receiving flushed objects in the bedpan, a plurality of flushing water inlets are distributed at the opening of the bedpan, nozzles are distributed in the flushing water inlet; the bedpanflushing water outlet is connected with the sewage tank through a drain valve, a vacuum generator is arranged on the sewage tank, and a flushing button for controlling flushing water to enter the bedpan is arranged between the bedpan and the clear water tank; and the toilet also comprises a control module used for controlling the work of the whole excrement collecting system. A vacuum intermittent design is adopted, the dirt box is not continuously in a vacuum state and is only in a vacuum mode to collect dirt when the bedpan is flushed, the number of locomotive toilets is very small and is generally two to three, the design can effectively save compressed air resources, in addition, components of the excrement collecting system are not continuously in a vacuum working environment, And the service life can be obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of locomotive toilets, in particular, to a vacuum space intermittent toilet collection system, a working method thereof, and a locomotive toilet. Background technique [0002] At present, passenger trains have begun to install vacuum toilet systems in batches, which greatly reduces the pollution of feces and dirt along the railway line and effectively protects the railway environment. [0003] However, compared with the improvement of the passenger train riding environment, the improvement of the working environment of locomotive drivers and passengers is relatively lagging behind, which is not conducive to driving safety and pollutes the environment. [0004] At present, only some locomotives are equipped with toilets, and most of the installed toilets use gravity flush or dry powder locomotive toilets, which are backward in technology and have many defects. Existing locomotive toilets consume a lot of wat...

AI Technical Summary

Problems solved by technology

[0003] However, compared with the improvement of the passenger train riding environment, the improvement of the working environment of locomotive drivers and passengers is relatively lagging behind, which is not conducive to driving safety and pollutes the environment

[0004] At present, only some locomotives are equipped with toilets, and most of the installed toilets use gravity flushing or dry powder locomotive toilets, which are backward in technology and have many defects

Existing locomotive toilets consume a lot of water for flushing, relying on water pressure and the self-weight of the dirt to collect the dirt, the flushing effect is poor, the airtightness is poor, and the odor is easy to leak, causing secondary pollution

[0005] Different from passenger trains, locomotives have a lot of equipment, and the space on and under the train is extremely limited. The vacuum toilets of ordinary passenger cars are less integrated and occupy a lot of space, so they cannot be installed directly on the locomotive.

Although the patent application for "A Locomotive Toilet Installed with Vacuum Squatting Pan" with application number 201710254717.2 discloses the idea of ​​installing a vacuum squatting pan on a locomotive, it adopts a vacuum holding type feces collection system, and its dirt box is always It is in a vacuum state, which undoubtedly wastes a lot of compressed air resources. At the same time, the components of the feces collection system are equivalent to being in a continuous working state, which also has a great adverse effect on the service life of each component.
