Description
Technical field
The present invention relates to a kind of refuse disposal installation, relate in particular to a kind of refuse disposal installation that can fully utilize house refuse.
Background technology
At present, domestic waste disposal method is varied, but most widely used up to now landfill, burning, three kinds of methods of compost of being still also have methods such as pyrolysis, sorting recovery, integrated treatment in addition.Wherein landfill method is the main method of China's garbage treatment; Domestic waste more than 90% adopts landfill disposal; Basically do not have the taking environmental conservation into consideration measure, or the part environmental practice is only arranged, it can cause severe contamination to environment on every side inevitably in the garbage disposal process.Simple and easy During High-Temperature Composting technology is generally used more in small and medium cities, but simple and easy compost project scale is less, mechanization degree is low, and environmental practice is incomplete.Simple and easy incinerator project scale is less, mainly utilizes transformations such as original coal pit or brickkiln to form, and technology is simple, cheap; Often lack basic air feed and smoke processing system, work under hard conditions, house refuse can't be able to abundant burning; Pollutant can not qualified discharge, and this type incinerator also has certain market in China, and mainly samll cities and towns use in some; Owing to can not satisfy environmental protection standard and burning condition, just progressively be banned.Domestic waste sorting recovery technology is comparatively reliable; The resource effect is better, and the resource material that sub-elects can directly be recycled, and this technology is that many developed countries are based on the first-selected treatment technology on the categorised collection basis; This technology addressing is more or less freely; But certain noise, odor pollution are arranged, and the domestic waste sorting recovery technology efficiency of separation is low, economic benefit is bad, and more residue is arranged after the sorting.At present domestic also have use domestic garbage treatment machine to handle house refuse; Domestic garbage treatment machine mainly contains following two kinds: first kind is the family expenses garbage disposer, and processing method is rubbish to be pulverized and got into sewer with garbage disposer to discharge, and the little function of family expenses processor volume is few; Can not fully utilize house refuse; Use the back water consumption bigger, sewer is prone to block, and causes very big waste and trouble for blowdown and water; Second kind is rubbish batch process machine; Processing method is rubbish to be concentrated pour the inner refuse container of processor into, no matter is to stir and pulverization process, and still separation and biochemical processed are all carried out in this container in the lump; And when also having free space in the container; Can continue to add in the container new a collection of rubbish, such processing method not only makes the flexibility of each processing capacity disposal of refuse and effect bad, and new and old garbage disposal degree difference can cause garbage disposal inhomogeneous.
Summary of the invention
Defective to the existence of existing domestic rubbish disposal aspect; It is a kind of under the situation that does not increase auxiliary water consumption that the present invention provides; Handling and carry out a biological disposal upon with pulverizing, plastics letter sorting, water-oil separating, siccative is the main processing unit, realizes the unit independent of garbage disposal, the pattern of handling process sequencing, makes up small-sized domestic rubbish disposal production line; Rubbish and biological organic synthesis are converted into biological product, the domestic garbage disposer that house refuse is fully utilized.
Addressing the above problem the technical measures of being taked is:
A kind of domestic garbage disposer; It is characterized in that: constitute by casing 1 and the compaction type pulverizer 2, biological processor 3, Polypropylence Sheet sorter 4, oil water separator 5 and the siccative processor 6 that are arranged in the casing 1; Wherein: the top in compaction type pulverizer 2 is provided with compaction type pulverizer charging aperture 21; Compaction type pulverizer discharging opening 24 is communicated with the Polypropylence Sheet sorter 4 that is arranged on its lower end, and Polypropylence Sheet sorter 4 is provided with Polypropylence Sheet delivery outlet 41, and the lower end of Polypropylence Sheet sorter 4 is connected with siccative processor 6; The upper end of oil water separator water pipe 54 is communicated with oil water separator 5; The bottom of oil water separator water pipe 54 is communicated with the lower end of siccative processor 6, and oil water separator driving pump 51 is housed on the oil water separator water pipe 54, and the middle part of oil water separator 5 and bottom are respectively equipped with oil export 52 and water out 53; Be provided with siccative agitator 61 in the casing of siccative processor 6; Siccative agitator 61 upper ends are connected with stirring drive motors 62, and the casing right side of siccative processor 6 is provided with siccative spiral propeller 63, and the left end of siccative spiral propeller 63 is connected with stirring drive motors 62 through chain; Siccative spiral propeller 63 is provided with siccative outlet 64, and siccative outlet 64 is communicated with the siccative casing 11 that is arranged on casing 1 bottom; Top in the biological processor 3 is provided with agitator 31; The left end of agitator 31 is connected with stirring motor 37; Time constant-temperature heater 32, precision temperature controller 33, biological treatment time controller 34 and refuse moisture controller 39 are housed on the disk of agitator 31 shells; Finished product inclination ejector 35 is equipped with in the lower end of agitator 31; No. three temperature sensors 38 are housed in the precision temperature controller 33, and the input of precision temperature controller 33, output signal and control cable are connected with single-chip microcomputer through No. three temperature sensors 38.
Beneficial effect of the present invention: the present invention handles with pulverizing, plastics letter sorting, water-oil separating, siccative and biological treatment is the main processing unit, can realize the unit independent of garbage disposal, the pattern of handling process sequencing, makes up small-sized domestic rubbish disposal production line; Rubbish and biological organic synthesis are converted into biological product, make garbage disposal even, each processing unit processes is flexible; Effective; Under the situation that does not increase auxiliary water consumption, utilize water circulation system that Polypropylence Sheet in the house refuse and grease are separated, can all the other house refuses and biological organic synthesis be converted into biological product after separating; Utilize biotechnology that house refuse is carried out organic synthesis and generated senior organic fertilizer and poultry feed; And can isolated grease be handled through biotechnology, itself and various additive are mixed and made into coarse biodiesel, effectively solved the waste oil problem; And twice laid and regeneration have been accomplished; Accomplish conversion rationally, reduce pollution, the conservation of nature ecological balance environment; The present invention with microprocessor as control module; Getting into refuse disposal installation from house refuse begins to be automatic control to the entire process process; Make the sequencing that is treated as of house refuse; According to working time and each power motor of the reasonable start and stop of work tempo of each several part needs, to reach purpose of energy saving.Measure back control temperature and reaction time for the biological agent that adds, and in heating, stir, react completely and product reaches standard to reach accurate control and homogeneous heating, to make.
