Abstract
The invention discloses a kind of mechanical feed packing course formula compost squatting pan, compound is used as by the use of materials such as wood chip, powder of straw, rice husk, wheat clothing, compound is set to increase automatically in blending bunker by the spring assembly of bottom, rotate voluntarily to feed when toilet bowl is rotated by cross template and fill out closet, and enter in-vessel composting system when rotating next time successively.Cross template rotation toilet bowl turns to in-vessel composting system after fecaluria is mixed with compound, forms the BAW packing course formula compositing systems for completing compost gradually from top to bottom.Dividing plate between blending bunker and in-vessel composting system forms the shielding system for isolating closet, in-vessel composting system, blending bunker with cross template rotation toilet bowl, does not make foul smell to indoor leakage, forms every smelly system.Squatting pan of the present invention can solve rural area flush toilet and connect electricity, water receiving, adapter inconvenience, the problem of follow-up sewage disposal is difficult to popularization, also the hygienic issues of existing countryside simple lavatory can be improved, also organic fertilizer can be produced by bio-toilet, realize the recycling of excrement.
Description
Technical field
The present invention relates to field of environment protection, it is related to a kind of device for the excrement for handling and causing environmental pollution, and in particular to
A kind of squatting pan with compost function.
Background technology
There are many problems always in the human feces processing of China rural area and remote districts.Existing rural toilet exists mostly
Simple and crude, sanitary condition is poor, the problem of arbitrarily discharge causes environmental pollution.And due to sparsely populated, build Domestic sewage collecting system
System is less efficient, therefore it is best processing method that treatment in situ, which is utilized,.Night soil progress compost treatment is converted into fertilizer makes
With being method that China rural area is commonly used in history, being also being capable for the treatment of in situ, the optimal path of recycling.But traditional pile formula
Composting mode takes up an area big, outdoor processing, produces odor pollution, causes the hygienic issues such as mosquitos and flies growth, current rural area less makes
With.Although some existing bio-toilets it is partial solve the problem of rural area goes to toilet, due to generally using raw ripe fertilizer mixing
, there is stink greatly, the problem of gas extraction system and high construction cost need to be installed in the mode of compost.Meanwhile, addition compost is mixed manually
Conjunction material reduces the clean-up performance of lavatory, ease of use is poor, therefore fails large-scale popularization in rural area and remote districts.Can be
It is much cleaner under lower cost, conveniently human feces are handled and realize that the bio-toilet of compost recycling has
Practical value.
The content of the invention
The problem of existing for more than, the invention provides a kind of mechanical feed packing course formula BAW every the ecological squatting pan of smelly type.
To achieve these goals, the technical scheme is that：
The present invention provides a kind of mechanical feed packing course formula compost squatting pan, and it includes crank handle 1, urinal 2, cross template
Rotate toilet bowl 3, charging restraining plate 4, charging aperture 5, leakage of urine hole 6, blending bunker 7, compound propeller 8, compound propelling spring
Device 9, spiral discharging device 10, packing course formula in-vessel composting system 11, dividing plate 12,
Dividing plate 12 is set in the middle of squatting pan, squatting pan is divided into blending bunker 7 and the two parts of packing course formula in-vessel composting system 11, blending bunker
7 tops are provided with charging aperture 5, and the top of charging aperture 5 sets the charging restraining control of plate 4 to enter the raw material that cross template rotates toilet bowl 3
