Description
The present patent application is on 02 26th, 2014 applying date, the divisional application of the patent of invention of application number 201410066905.9.
Technical field
The present invention relates to a kind of composting device, particularly relate to a kind of movable earthworm bed composting device.
Background technology
Lumbricus self one ton of fresh Lumbricus of weightening finish, about to consume 70～80 tons of organic wastes, can produce about 20～40 tons of earthworm excrement.Vermicomposting technology is the promotion organic material decomposition transformation function being had in natural ecosystems based on Lumbricus, and grow up one processes and the biologic treating technique of the organic moiety in urban domestic sewage sludge for solid waste compost.It is introducing Lumbricus on the basis of sludge composting, make Lumbricus in compost treatment sludge process, seek suitable nutrient substance as food, mud is discharged to the last form with wormcast in entering Lumbricus body, i.e. be equivalent to the sludge treatment technique of complete set, the biochemical action of enteric microorganism in the chemical action of the most existing Lumbricus Bodily secretions and Lumbricus body, also has the physics chemical action such as grinding, digestion.During whole, do not only have the phagocytosis Digestion of Lumbricus, and owing to its special biological function is added in Lumbricus activity in mud, accelerate the activity of microorganism in mud, Lumbricus and microorganism synergism thus accelerate the decomposition and inversion of organic substance in mud and the absorption of heavy metal and change the form of heavy metal, reduce poisonous and harmful element in mud, increase the fertility of the compost based on earthworm excrement, breeding earthworm has multiple use simultaneously, so that solid waste and the remaining mud of sewage disposal are really achieved " minimizing, innoxious, stabilisation, resource " remarketing, and realize comprehensive increment resource recycling.But existing Vermicomposting technology is typically with on earthworm bed the mode of static breeding earthworm compost, it is longer to there is the time cycle in which, cultivates the shortcomings such as inefficient, and its economic benefit and social benefit have bigger room for promotion.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, cultivation, movable earthworm bed composting device that composting efficiency is high.
The object of the present invention is achieved like this:
A kind of movable earthworm bed composting device, it is characterised in that: it includes a fermentation tank；The bottom of this fermentation tank is made up of support bar, bearing and silk screen；Described support bar is many, and its one end is fixed on the tank body lower end of fermentation tank, and the other end is fixed on described bearing；Described silk screen is arranged on the bottom of support bar and bearing；The inside of described fermentation tank is fixed with a rotary shaft, and this rotary shaft connects the blade of continuous helical shape.
As optimizing further, the top of above-mentioned fermentation tank is also correspondingly arranged on support bar and bearing, and its support bar is many, and one end is fixed on the tank body upper end of fermentation tank, and the other end is fixed on described bearing；The two ends correspondence of described rotary shaft is arranged in the bottom of fermentation tank and the bearing at top.Or, as optimizing further, above-mentioned fermentation tank is also provided with movable upper cover, and this movable upper cover is corresponding to being also equipped with bearing at the bearing of fermenter base.This setting further ensures stability when rotary shaft rotates in fermentation tank；And when being set to movable upper cover, this activity earthworm bed just can facilitate open upper opening, and rapidly joins the mud mixing organic waste raw material continuously, or realize semiclosed when fermentation in case Lumbricus escapes.
As optimizing further, above-mentioned fermentation tank is specially cylindrical shape；Above-mentioned many support bar circumferentially deciles arrangement so that its be more uniformly stressed, aesthetic appeal.The blade of above-mentioned continuous helical shape, along the longitudinally perpendicular direction of rotary shaft from lower end or the lower end of movable upper cover of fermentation tank top, extends to the upper end of fermentation tank bottom web.By this setting, after movable earthworm bed starts, external motor drive rotary shaft, thus drive the blade of continuous helical shape to start to wriggle, and then achieve the stirring of whole materials in fermentation tank in this activity earthworm bed, maintain efficiently being smoothed out of aerobic fermentation process.
As optimizing further, the tank body outer surface of above-mentioned fermentation tank, it is additionally provided with heating system.This heating system is concrete as the tank body outer surface at fermentation tank can be used to realize around mode of heatings such as arrangement heating wire, with by this setting, can realize the external heat in fermentation tank according to actual operation requirements.As further optimizing, the height of said heating system is not higher than 1/3rd of above-mentioned fermentation tank tank body height, and is that many groups are around arrangement.If temperature is less than 20 DEG C, then by opening this heating system, temperature-controlled and keep the bottom temp in fermentation tank at about 25 DEG C, intermediate layer keeps about 20 DEG C, and upper strata is maintained at about 15 DEG C, with suitable earthworm movement.
As further optimizing, above-mentioned rotary shaft is hollow structure；And in this hollow rotary shaft, it is additionally provided with through hole.The setting of this through hole, can make when hollow rotary shaft rotates, and is flowed by air or the device such as aerator is passed through air in this fermentation tank, and realize well keeping ventilating and aerobic fermentation process.The bottom of above-mentioned fermentation tank is additionally provided with multiple spikes.By this setting to be supported by this fermenter base, leave, with ground distributor, the space length keeping certain, in order to discharge the matured compost of mixing earthworm excrement and derive ripe Lumbricus.
The method have the advantages that
Present configuration is simple, easy to use.When being applied in Vermicomposting technology, earthworm movement scope is concentrated mainly on intermediate layer, has the most both maintained upper strata and has been continuously added to mix the mud of organic waste raw material, and lower floor again can output earthworm excrement and become thoroughly decomposed fertilizer continuously.Using this movable earthworm bed, through 30 days culture fermentings, Lumbricus well-grown, multiply vigorous, compost maturity effect is high；Its fermentation reactor system process, comparative static breeding earthworm compost, time cycle shortening about 10 days, efficiency exceeds 46%, has bigger economic benefit and social benefit.
