Description
Technical field
The invention belongs to the sanitary equipment field, particularly, the present invention relates to a kind of fecaluria treatment facility that is used for ecological flush-free toilet and comprise its ecological flush-free toilet, described fecaluria treatment facility can make fluid separation applications such as solid such as ight soil and urine, processing respectively.
Background technology
Existing flush-free toilet mainly contains two kinds of forms: packing formula flush-free toilet and ecological flush-free toilet.Packing formula flush-free toilet need expend packaging material (as polybag), and higher use cost is not only arranged, clear cost, and because the refractory organics of plastic products has more brought secondary pollution; In addition, colostomy bag freezes easily in severe cold weather, and low temperature adaptability is poor, has limited the area that is suitable for.
And ecological flush-free toilet is by the biochemical degradation effect of aerobic microbiological night soil to be carried out resource, innoxious and minimizing processing on the spot, has overcome the defective of packing formula flush-free toilet.There have been at present many configurations differences, the different ecological flush-free toilet of structure to come out, for example, disclosed ecological flush-free toilets such as Chinese patent CN1189253C and Chinese patent or patent application CN1773034A, CN2761126Y, except being placed in fixed-site, they also can be widely applied to mobile places such as train, automobile (as, can be referring to Chinese patent CN2803845Y, CN2801575Y, CN2838507Y).Yet, round in the fecaluria treatment facility in these existing ecological flush-free toilets (being also sometimes referred to as biochemical reactor, main frame etc. in the prior art) and squatting pan bottom directly is communicated with, and the toileting person is easy to directly see that also might touch the round internal mix has internal units such as the fecaluria degradation product of microbial bacterial agent and agitator.Although improved smell greatly under the effect of microbial bacterial agent, this also gives on the toileting person visual perception and has brought uncomfortable feeling; Secondly, after the toileting person enters the lavatory, when sideboard is opened, for the sake of security, generally to close agitator, if go to toilet the frequency height, close and be unfavorable for that very fecaluria and microbial bacterial agent mix and ventilation, influence the degradation efficiency of microorganism to fecaluria in long-term pass; In addition, especially children stretch into round inside with hand sometimes out of curiosity, even and the more sharp-pointed agitator in edge when shutting down also than being easier to cause danger.For this reason, No. the 200710143603rd, Chinese patent application and PCT application PCT/CN2007/002591 disclose a kind of fecaluria treatment facility that is used for ecological flush-free toilet, and it has increased the device that scrapes that can temporarily store the temporary transient manure buffer of fecaluria and do not have palp sharp edges when going to toilet.
Yet a hole (or being called the hole) is only established in the squatting pan bottom in the ecological flush-free toilet of these existing routines, is regardless of urine and ight soil solid and all directly enters the fecaluria treatment facility from this hole, the function that does not have excrement and urine to separate.And, because the water content difference of ight soil and urine is very big, fecaluria treatment facility of the prior art (is also sometimes referred to as biochemical reactor in the prior art, main frame etc.) microbial bacterial agent in (can referring to as, Chinese patent CN1189253C, No. the 200710142813.4th, Chinese patent application CN1916163A and the Chinese patent application submitted on July 30th, 2007, the PCT patent application of submitting on August 28th, 2007 PCT/CN2007/002591 number) needing relatively usually, dry environment ferments, make the ight soil decrement, therefore when urine is many, just need the continuous work of heater in the fecaluria treatment facility to keep dry, need to consume a large amount of electric energy.
Although Chinese patent application has designed a kind of new squatting pan that is used for ecological flush-free toilet for 200710165478.X number and No. 200720195828.2, it has increased logical urine hole and protrusion, make when normal the use, the urine that the man toilet user discharges can be collected in the storage urine container by logical urine hole, and does not directly enter in the fecaluria treatment facility that microbial bacterial agent is housed.But this squatting pan can only prevent that male toilet user's urine from directly entering in the fecaluria treatment facility that microbial bacterial agent is housed, and all toilet users' urine can both be collected in the storage urine container; And, when water cleans squatting pan, when especially cleaning around the defaecation hole, still inevitable water for cleaning directly enters the fecaluria treatment facility, thereby has influenced the fermentation process efficient of microorganism wherein or pay too much electric energy heating evaporation and fall these water.
In order to overcome the defective of prior art, satisfy the needs of current energy-saving and emission-reduction, the inventor is by painstaking efforts, on the basis of disclosed fecaluria treatment facilities such as No. the 200710143603rd, Chinese patent application and PCT application PCT/CN2007/002591, designed an equipment for separating liquid from solid, not only can solve the problem of Separation of Solid and Liquid such as fecaluria inexpensively, and through experiment to a large amount of crowd's fecalurias, optimized the diameter in the position and the hole of its mesopore, make the ight soil solid be not easy plugging hole, also be not easy to enter storage urine container, thereby can use stably in a long term.Such design has also brought a unexpected advantage, promptly when staff's water daily cleaning squatting pan or lavatory, need not to worry that too much water for cleaning directly enters the fecaluria treatment facility, thus the cleaning in more convenient corresponding lavatory.
