Double-room-alternately-used unidirectional-exhausting dung-urine-separated dry latrine

Abstract

The invention discloses a double-room-alternately-used unidirectional-exhausting dung-urine-separated dry latrine. The double-room-alternately-used unidirectional-exhausting dung-urine-separated dry latrine comprises an upper-layer use room and a lower-layer double-room dung storage tank, wherein a dung-urine separate collected squatting toilet which comprises a urinal and a stool pit is arranged in the upper-layer use room, the urinal is communicated with a urine storage device through a urine conveying pipe, and the stool pit is communicated with the lower-layer double-room dung storage tank through a gravity type automatic-reset isolation valve; the lower-layer double-room dung storage tank comprises a dung storage tank partition wall, which is used for partitioning the dung storage tank into two rooms, and a dung steering groove which is connected to the dung storage tank partition wall and can be used for steering, and the dung steering groove is used for guiding dung, which falls from the automatic-reset isolation valve, into one room of the double-room dung storage tank; a sun-shone plate is arranged at a dung outlet of the lower-layer double-room dung storage tank; in order to prevent rainwater from entering, the ground level of the upper-layer use room and the surrounding tank walls of the lower-layer double-room dung storage tank are higher than the outside ground of the use room. The alternate fermentation and aging function for the double-room dung storage tank is realized; the double-room dung storage tank is provided with an exhausting pipe, and the problem of odor of the double-room dung storage tank is solved through combining the exhausting pipe and the automatic-reset isolation valve.

Description

technical field [0001] The invention belongs to the field of water-saving dry toilets, in particular to a dry toilet with two chambers alternately using one-way exhaust and separating excrement and urine. Background technique [0002] Most of the household toilets in the vast rural areas of our country are very simple, mostly simple open-air squat pits or open-air squat pits connected with septic tanks, and both septic tanks and squat pits are open. Farmers with better conditions have built small rooms for shelter from wind and rain on the pits. Traditional rural household toilets have the following three major problems: First, feces and urine are not separated, and after accumulation and fermentation, odorous toxic and harmful gases such as ammonia and hydrogen sulfide are produced; second, feces are difficult to ferment and mature, and it is difficult to kill pathogenic microorganisms and The eggs of parasites are easy to cause infectious diseases; the third is to breed m...

Problems solved by technology

Traditional rural household toilets have the following three major problems: First, feces and urine are not separated, and after accumulation and fermentation, odorous toxic and harmful gases such as ammonia and hydrogen sulfide are produced; second, feces are difficult to ferment and mature, and it is difficult to kill pathogenic microorganisms and Parasite eggs are easy to cause infectious diseases; the third is to breed mosquitoes and flies, and squatting in the pit during the summer rainstorm is easy to flood Jinshan and sewage to flow across

But there are still such and such problems, for example: (1) the construction, use and maintenance are complicated, and the cost is high; (2) the three major problems of the above-mentioned traditional rural dry toilets have not been fully resolved; (3) people's toilet habits have been changed, Looking directly at the deep and large septic tank under the urinal, people often feel fear; (4) It is difficult to add covering materials after defecation, and it is difficult to add more covering materials. It is also a problem; (5) the existing technology solves the double-chamber alternate use problem of the excrement and urine separation dry toilet by adopting the snap-in movable structure toilet, and the water, rainwater, urine, etc. of the squatting pan are cleaned up by the urinal, the snap-in movable The gaps around the structural urinal, the exhaust pipe, etc. enter the septic tank, or the exhaust pipe is unreasonably set up, which will easily cause serious odor in the toilet
