Description

Anti-freezing vacuum public toilet with flushing pipe capable of being emptied

Technical Field

The utility model relates to a vacuum public latrine technical field, concretely relates to anti-freezing vacuum public latrine of wash pipe evacuation.

Background

As an advanced environmental protection equipment, vacuum toilet systems have been widely used at home and abroad, and application fields include various public transportation fields including: train, coach, ship, airplane, building, etc. The vacuum toilet is a technology integrating environmental protection, water saving, sewage collection, raw water recycling and a green fertilizer making system. A small amount of flushing water is added into sewage through a vacuum pipeline, and excrement is collected into a preset vacuum sewage holding tank. Compared with the traditional toilet, the vacuum toilet system has the advantages of water consumption saving, good flushing effect, good odor control, convenient installation and the like: the traditional water-saving toilet generally uses 6 liters of water each time, and after the vacuum technology is adopted, the flushing water used for flushing the toilet each time can be less than 0.8 liter; the traditional toilet is of a water flushing type, so that part of odor still stays in the air after a user uses the toilet, and after the toilet adopts a vacuum technology, the odor cannot be diffused into the air because negative pressure is sucked from outside to inside, so that the problems of small space, unsmooth air and odor existing in the traditional toilet can be thoroughly solved; the vacuum toilet can be adjusted and adapted along with the curve shape trend of a structure for the installation of an internal pipeline because negative pressure is used as a power source, the traditional toilet mainly realizes the emptying function by relying on gravity, and the pipeline installation of the traditional water-saving toilet is limited by the requirement on the gravity; the vacuum toilet adopts the negative pressure source, the pipe diameter of the conveying can be adjusted according to the installation requirements on site, the conveying pipe diameter is greatly reduced to about one third of the original pipe diameter, and the system is mainly applied to large pleasure boats, airplanes and fast trains at present and can also be applied to building places such as houses, hotels and the like.

When the vacuum toilet is used in areas such as plateaus and the like, particularly in cold areas, liquid in a flushing pipe pipeline in the vacuum toilet is extremely easy to freeze, so that the flushing pipe pipeline is blocked, and the vacuum toilet in the cold areas on the plateaus cannot be normally used. The mainstream technology for preventing the vacuum toilet from being unavailable due to icing of the flushing pipe of the vacuum toilet in the market at present is to heat the residual liquid in the pipe in a mode of winding a heat tracing band on the outer wall of the flushing pipe or arranging an electric heating wire in the flushing pipe.

However, the existing vacuum public toilet technology still has the defects that:

the metal pipe is required to be used for heating the pipeline in a mode that the heat tracing band is wound on the pipeline wall of the flushing pipe, the metal pipe has stable and good heat conducting performance, but the plastic pipe does not have the good heat conducting performance, but the metal pipe is easy to corrode the metal pipe due to rusting after being used for a long time, so that the metal pipe needs to be replaced periodically, the manufacturing cost of the whole vacuum toilet is increased, and the popularization is not facilitated; the mode that sets up the heating wire in the wash pipe pipeline, because the heating wire also is metal material, the heating wire does not use for a long time in the high temperature environment in summer and soaks also easily to cause the rust of heating wire and damage in liquid for the life of heating wire is short, and this kind of mode also can improve the manufacturing cost of whole vacuum toilet.
