Description

Outdoor water closet structure capable of preventing freezing and saving water

Technical Field

The utility model belongs to the environmental protection equipment field relates to environmental protection lavatory technique, especially an outdoor toilet structure of water conservation prevents frostbite.

Background

China is a water-poor country, and in some northwest regions, the situation of relatively serious water resource shortage still exists. In the water-poor areas, the rural areas are more serious than the urban areas, the pipeline for daily water consumption can only be used for solving the draught problem of local people, and the excrement collection problem of the local people can only depend on dry toilets or centralized public flushing toilets.

The layout mode of the dry latrine is originally rough, and is mostly processed by each user independently, so that large-scale orderly collection and processing are difficult to realize, and the processing mode is difficult to operate and can cause adverse effects on the living environment of the village. In order to solve the above problems, a centralized public toilet is a better solution. The public flushing toilet is generally built in an outdoor public area of a country, and has certain defects in the actual use process, especially in winter in northern areas of China.

The urinal discharge port of the existing centralized public flushing toilet is generally directly communicated with the septic tank by adopting a vertically arranged pipeline in order to prevent the excrement from being blocked, which causes some problems. A large amount of moisture carried in the flushing process can be directly introduced into the septic tank, excrement in the septic tank can be frozen in cold winter, and then the whole toilet is blocked and cannot be used. In order to solve the above problems, some toilets have a stool with a function of separating liquid and feces, but such an operation may cause too low moisture in the feces and further make it difficult to extract the feces from the septic tank.

Therefore, there is a need for an outdoor toilet design that effectively controls water, saves water, and prevents freezing.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art, provide a rational in infrastructure, excrement and urine and the passive separation of liquid, low cost's outdoor water closet structure of water conservation prevents frostbite.

The utility model adopts the technical proposal that:

the utility model provides an outdoor toilet structure of water conservation prevents frostbite, includes wash water formula urinal and septic tank, the septic tank is located wash water formula urinal below, and the discharge port and the septic tank of wash water formula urinal are linked together its characterized in that: a communicating pipe is arranged at the discharge port of the flushing type septic tank and comprises an inclined pipe part, straight pipe parts are respectively and integrally manufactured at the two side ends of the inclined pipe part, an included angle formed by the two straight pipe parts and the inclined pipe part is an obtuse angle, the axial extension directions of the two straight pipe parts are mutually parallel, two straight pipe parts of the communicating pipe are embedded and installed along the vertical direction, the two straight pipe parts are respectively communicated with the discharge port of the flushing type urinal and the feed port of the septic tank, an opening is hollowed in the side wall of the lower part of the inclined pipe part of the communicating pipe, a water filter screen is arranged in the opening, the inner edge of the opening extends towards the outer side of the communicating pipe and is integrally provided with a water collecting hopper, the water outlet end of the water collecting hopper is communicated with a sewage recovery tank, the water outlet end of the sewage recovery tank is provided with a filter, and the recovered water filtered by the filter can be led into a flushing water tank of the flushing urinal.

And the septic tank is pre-buried in 2.5 meters below the earth's surface and below, and the septic tank outside cladding has the heat preservation.

And the water outlet end of the sewage recovery tank is communicated with the water collecting tank through a pipeline, a submersible pump is installed in the water collecting tank, and the water outlet end of the submersible pump is communicated with a water outlet of the flushing type urinal.

Moreover, the angle formed by the inclined pipe part and the straight pipe part is larger than 90 degrees and smaller than 140 degrees.

The utility model has the advantages that:

the utility model discloses in, improve and the design to the structure of communicating pipe, become the tubular structure of straight tube formula to down tube portion and straight tube portion matched with bent pipe structure, excrement and urine is the position that gets into the discharge pipe at the urinal most easily glues glutinous adnexed position in complete processing procedure, and inferior is in the position that discharge pipe and septic tank are connected, is hardly appearing blockking up at the in-process of the water conservancy diversion of washing by water. The communicating pipe structure designed in the water closet structure is provided with a straight pipe structure at the position connected with the urinal and the septic tank, so that the contact chance of excrement and urine with the pipeline can be reduced, and blockage is avoided; the inclined pipe is arranged to play a role in guiding and buffering water flow in the flushing process, and in the flushing process, the water flow clamps excrement and urine to be guided out along the straight pipe part and then is buffered and decelerated through the inclined pipe, so that the excrement can slide along the lower side wall of the inclined pipe, and in the sliding process, part of water flow is guided into the water collecting hopper after being filtered by the water filter net under the action of self weight, so that moisture and the excrement are passively separated, and therefore, the septic tank can be guaranteed to have proper humidity, and part of waste water can be recycled and filtered for secondary utilization under the condition that the septic tank is convenient to draw out and is not easy to freeze; the septic tank is pre-buried 2.5 meters below the ground surface, is suitable for most areas in China, and the environment temperature below the position is generally above zero DEG C; the design of pipe chute portion and straight tube portion angle is guaranteeing under excrement and urine can smoothly derive its inside prerequisite, can prolong rivers and faecal time in the pipe chute portion, and then filters more moisture.
