dry toilet

Abstract

The invention relates to a dry toilet, which includes a supporting frame as a carrier, adopts a welding mechanism, and includes an upper platen arranged on the ground; a cushion material buffer warehouse is arranged on the rear side of the upper end of the upper platen, and the cushion material is stored in advance; the cushion material enters the The material spiral part is located under the upper platen and the inlet is set at the outlet of the lower end of the cushion material buffer warehouse, which is used for horizontally pushing the cushion material; the collecting tank bucket is set on the cushion material feeding spiral part to accept the output of the cushion material feeding spiral part The material; the urinal is arranged on the upper platen, and the lower end of the feeding slot at the upper end of the middle part is connected with the collecting tank; the inlet of the material barrel is arranged under the collecting tank; the invention has reasonable design, compact structure and convenient use.

Description

technical field [0001] The invention relates to an aqua toilet, which is suitable for both squatting toilets and sitting toilets. Background technique [0002] With the implementation of China's rural toilet revolution and rural revitalization plan, it is required to carry out harmless treatment of rural family toilet excrement. Most of the farmers in the north who lack water use dry toilets. The traditional dry toilet excrement is exposed to the air and breeds flies. Mosquitoes, stinking, polluting the environment; currently, the newly improved aqua toilets use urine and feces to separate dry and wet to treat feces separately. Once sawdust, straw powder, ... and other fermentation media cover the stool, the fermentation period is long, and the odor during the fermentation is emitted and seriously pollutes the environment; there have been related reports on the new technology of dry toilets, which are published in CN204813659U "A Composting Rural Area In Sanitary Dry Toilet...

[0002] With the implementation of China's rural toilet revolution and rural revitalization plan, it is required to carry out harmless treatment of rural family toilet excrement. Most of the farmers in the north who lack water use dry toilets. The traditional dry toilet excrement is exposed to the air and breeds flies. Mosquitoes, stinking, polluting the environment; currently, the newly improved aqua toilets use urine and feces to separate dry and wet to treat feces separately. Once sawdust, straw powder, ... and other fermentation media cover the stool, the fermentation period is long, and the odor during the fermentation is emitted and seriously pollutes the environment; there have been related reports on the new technology of dry toilets, which are published in CN204813659U "A Composting Rural Area In Sanitary Dry Toilet Box, it is disclosed that the feces are separated from urine and feces first, the urine is collected, and then the dry powder or liquid of microorganisms is sprinkled on the stool for natural composting. There is an odor during fermentation that volatilizes and pollutes the environment. Natural composting belongs to The surface of the raw material is in contact with the air, and there is no oxygen supply inside the raw material. Natural composting has a slow fermentation speed, which requires a large volume of the fermentation tank and a large area. To pile up and fill up the fermentation tank, it is often necessary to manually remove the fermentation products in the fermentation tank; in CN108433622A "An Environmentally Friendly Dry Toilet Without Water and Electricity", it is disclosed that the urine and feces are separated from the wet and dry, the urine flows into the urine collector, and the stool enters the Stool collection barrel, sprinkle crushed straw and sawdust on the stool in the stool for natural composting and fermentation, there is an odor during fermentation that volatilizes and pollutes the environment, the fermentation speed is slow, and the volume of the fermentation tank is large, especially for fermentation There is no stirring machine in the barrel, which leads to incomplete fermentation of feces, and the fermentation products are easy to accumulate and fill up the fermentation barrel; in CN100387174C "excrement treatment device, environmental protection toilet using it and excrement treatment method", it is disclosed that urine enters the toilet to ferment The method of biodegradation in the tank, the harmful odor generated in the fermentation of urine and feces has not been harmlessly treated, which seriously pollutes the living environment of the farmhouse. There is no air inlet pipe required for aerobic degradation in the fermentation tank, and only the fermentation tank materials Surface air contact, fermentation materials can not be in contact with sufficient air, it is a natural composting fermentation method with insufficient oxygen supply, resulting in slow degradation of feces and urine, long fermentation time, generally takes a few days to compost Human excrement is converted into organic fertilizer, which increases the unit processing volume and floor area of ​​the fermentation tank; in particular, a stirring device with a helical blade is used, and the helical blade has the objective function of material transportation and movement when rotating. Therefore, When the helical blade on the mixing device rotates, the fermented material in the treatment tank moves from one end of the treatment tank to the other end, and the fermented material (excrement, sawdust and microorganisms) is easily compacted into blocks and boards, and the fermented material Not loose, which greatly affects the biochemical degradation effect of excrement; in particular, according to the principle of biochemical fermentation, the aerobic fermentation water of excrement should be controlled at 50-60% (Wt%), and the urine enters the fermenter to make the fermented material Moisture content higher than 60% (Wt%), reducing the good The biological activity of aerobic microorganisms reduces the biochemical decomposition efficiency of excrement, and it is necessary to increase the excess water evaporated by electric heating to 50-60% (Wt%), which increases the processing cost of excrement decomposition
