Description
The present patent application is the patent of invention for February 26 2014 applying date, application number 201410066905.9
Divisional application.
Technical field
The present invention relates to a kind of composting device more particularly to a kind of movable earthworm bed composting devices.
Background technique
Earthworm itself one ton of fresh earthworm of weight gain, will about consume 70~80 tons of organic wastes, can produce about 20~40 tons of earthworm excrement.
Vermicomposting technology is to be based on earthworm possessed promotion organic material decomposition transformation function in natural ecosystems, and develop
Biologic treating technique of one to get up for the organic moiety in solid waste compost processing and urban domestic sewage sludge.
It is to introduce earthworm on the basis of sludge composting, makes earthworm in compost treatment sludge process, seeks suitable nutriment and makees
For food, sludge enters in earthworm body to be discharged in the form of wormcast to the end, that is, the Treatment of Sludge work of complete set
Skill, around here in the chemical action of existing earthworm Bodily secretions and earthworm body enteric microorganism biochemical action, there are also grinding,
The physics chemical actions such as digestion.In the whole process, not only there is the phagocytosis digestion of earthworm, but also since earthworm is in sludge
Activity add its special biological function, accelerate the activity of the microorganism in sludge, earthworm cooperates with work with microorganism
With to accelerate the form of the decomposition and inversion of organic substance and the absorption of heavy metal and change heavy metal in sludge, sludge is reduced
Middle poisonous and harmful element increases the fertility of the compost based on earthworm excrement, while there are many purposes for breeding earthworm, to keep solid useless
Gurry and the remaining sludge of sewage treatment are really achieved the remarketing of " minimizing, innoxious, stabilisation, recycling ", and realize
Comprehensive increment recycling recycles.However existing Vermicomposting technology is usually utilized on earthworm bed static breeding earthworm compost
Mode, the disadvantages of which is longer there are the time cycle, and breeding efficiency is lower, economic benefit and social benefit have larger
Room for promotion.
Summary of the invention
The high movable earthworm bed composting device of simple, cultivation that the purpose of the present invention is to provide a kind of structures, composting efficiency.
The object of the present invention is achieved like this:
A kind of activity earthworm bed composting device, it is characterised in that: it includes a fermentor；The bottom of the fermentor is by bracket
Item, bearing and silk screen composition；The bracket item is more, and one end of which is fixed on the tank body lower end of fermentor, the other end is fixed on
On the bearing；The silk screen is mounted on the bottom of bracket item and bearing；The inside of the fermentor is fixed with a rotation axis,
The blade of continuous helical shape is connected in the rotation axis.
As advanced optimizing, the top of above-mentioned fermentor is also correspondingly arranged on bracket item and bearing, and bracket item is more
Root, one end are fixed on the tank body upper end of fermentor, and the other end is fixed on the bearing；The corresponding installation in the both ends of the rotation axis
In the bearing of the bottom and top of fermentor.Alternatively, above-mentioned fermentor is also provided on movable as advanced optimizing
Lid, the movable upper cover correspond to fermenter base bearing at be also equipped with bearing.The setting further ensures rotation axis
Stability when being rotated in fermentation tank；And when being set as movable upper cover, which can facilitate open upper
Opening, and continuously rapidly joins the sludge for mixing organic waste raw material, or realizes in fermentation semiclosed to prevent earthworm escape.
As advanced optimizing, above-mentioned fermentor is specially cylindrical shape；Above-mentioned more bracket items circumferentially arrange by equal part,
So that it is more uniformly stressed, aesthetic appeal.The blade of above-mentioned continuous helical shape, it is spontaneous along the longitudinally perpendicular direction of rotation axis
The lower end of lower end or movable upper cover at the top of fermentation tank, extends to the upper end of fermentation tank bottom web.By the setting, in work
After dynamic earthworm bed starting, rotation axis is driven by external motor, so that the blade of continuous helical shape be driven to start to wriggle, and then is realized
In the activity earthworm bed in fermentation tank whole materials stirring, maintain efficiently going on smoothly for aerobic fermentation process.
As advanced optimizing, the can outer surface of above-mentioned fermentor is additionally provided with heating system.The heating system is specific
It such as can be used and realized in the can outer surface of fermentor around arrangement heating wire heating method, it, can root to pass through the setting
The external heating in fermentation tank is realized according to actual operation requirements.As further optimization, the height of said heating system
It not higher than the one third of above-mentioned fermentation tank height, and is multiple groups around arrangement.If temperature is lower than 20 DEG C, by opening
Open the heating system, temperature-controlled and keep the bottom temp in fermentor at 25 DEG C or so, middle layer keep 20 DEG C or so,
Upper layer is maintained at 15 DEG C or so, to be suitable for earthworm movement.
As further optimization, above-mentioned rotation axis is hollow structure；And in the hollow rotation axis, it is additionally provided with through-hole.
The setting of the through-hole may make in the rotation of hollow rotation axis, through devices such as air flowing or air blowers in the fermentor
It is passed through air, and realizes holding ventilation and aerobic fermentation process well.The bottom of above-mentioned fermentor is additionally provided with multiple supports
Foot.By the setting to support the fermenter base, the space length for keeping certain is left with ground distributor, in order to arrange
The matured compost of earthworm excrement is mixed out and exports mature earthworm.
The invention has the following advantages:
It is the configuration of the present invention is simple, easy to use.When applied in Vermicomposting technology, earthworm movement range is concentrated mainly on
Middle layer had both maintained upper layer in this way and has been continuously added to mix the sludge of organic waste raw material, and lower layer again can continuous output earthworm excrement and corruption
Ripe fertilizer.Using this movable earthworm bed, through 30 days culture fermentings, earthworm well-grown multiplied vigorous, compost maturity effect height；
Its fermentation reactor system process, comparative static breeding earthworm compost, time cycle shorten about 10 days, and efficiency is higher by 46%, have biggish
Economic benefit and social benefit.
