Description

Bacteria residue compost fermentation air-breather

Technical field

The utility model belongs to compost fermentation equipment technical field, and in particular to a kind of bacteria residue compost fermentation air-breather.

Background technology

Bacteria residue is the culture medium waste remained after culturing edible fungus, and main component includes cellulose, lignin, hemicellulose Element, mycoprotein, vitamin and mineral element etc..China can produce due to being big country of mushroom producing after annual edible mushroom collection Raw substantial amounts of bacteria residue, most of bacteria residues are abandoned or burned as discarded object, but it is found that bacteria residue is also containing abundant battalion Material is supported, can be recycled.Mainly have for the common recoverying and utilizing method of bacteria residue at present：(1) Tian Zuofei is directly returned Material；(2) edible mushroom secondary cultivation raw material；(3) it is used as feed；(4) it is used as horticultural gardening matrix.

Bacteria residue before the use often over compost fermentation processing, due to bacteria residue compost fermentation compost different phase all The intervention of oxygen is needed, and the vegetative activity of microorganism can consume the oxygen in composting system in composting process, therefore it is existing Bacteria residue compost fermentation mode mostly need needed after stack retting certain time using fertilizer turning-over machine carry out turning, increase bacteria residue and The contact of air, the abundant fermentation of bacteria residue could be realized.But not only needed by the way of fertilizer turning-over machine turning larger place, Operation inconvenience, and it is high additionally to produce machine cost, economic benefit, if therefore one kind can be developed need not lodge in turning over fertilizer Keeping condition can be achieved in machine turning, it will is brought great convenience to bacteria residue compost fermentation.

Utility model content

The purpose of this utility model is exactly in order to solve the above-mentioned technical problem, and to provide a kind of bacteria residue compost fermentation ventilation dress To put, need not can be achieved to contact with oxygen inside bacteria residue using fertilizer is turned over, ventilatory effect is good, and fermentation process is easily controlled, Fermentation is quick thorough.

To achieve these goals, the technical solution adopted in the utility model is：A kind of bacteria residue compost fermentation air-breather, Including the airway positioned at fermentation tank side wall, described airway one end is stretched into inside fermentation tank, the other end and supply Device connects；More discharge ducts, more rows are set along pipeline radial distribution on the airway inside fermentation tank Along pipeline, axially helically formula is distributed feed channel, and multiple steam vents are arranged at intervals with every discharge duct.

Air-breather provided by the utility model, can be without carrying out when bacteria residue compost fermentation in fermentation tank In the case of turning over fertilizer, you can realize to the ventilation inside bacteria residue, airway one end need to be only connected with feeder, air or Oxygen can enter fermentation tank by airway, more discharge ducts being distributed on airway, can by air or Oxygen imports inside bacteria residue heap body well.The multiple steam vents helically set on the discharge duct of formula distribution, can be to bacterium Good ventilatory effect is realized at each position of slag muck body, so as to accelerate the process of fermentation.

Further, in above-mentioned air-breather, the more discharge ducts are distributed in such a way：Along perpendicular to logical In the section A in airway direction, each three discharge ducts of cross-sectional distribution, angle α between adjacent two discharge ducts= 120°.On two neighboring section, discharge duct on the one of section discharge duct adjacent with another section it Between angle β=60 °.

Using the distribution mode of above-mentioned discharge duct, multiple directions can be met to real inside bacteria residue heap body in same section Now maximized ventilatory effect, and do not conflict between the ventilating mode of adjacent sections, ventilatory effect is good.

Further, along in the section A perpendicular to airway direction, the discharge duct length in same section is consistent, The discharge duct length of adjacent sections is incremented by successively or successively decreases, on the one hand the design of the structure can maintain in bacteria residue heap body very well Gas flow balance, on the other hand can realize good ventilatory effect to the bacteria residue heap body of different depth.

Further, in being staggered, steam vent avoids ventilating by the way of being staggered in the direction of the steam vent When gas only be passed through in one direction, in multiple alternate directions simultaneously be passed through gas, can play preferably supply effect, it is right Compost fermentation is favourable.

Further, the feeder includes aerator, can be directly to providing oxygen inside heap body.

Further, control valve is installed on the airway being connected with feeder, can be according to throughput and ventilation Time judges whether that needs continue to be passed through gas, determines whether closing control valve, convenient to control throughput.

Further, filter screen is set on the steam vent, can prevents the Large Slag thing in fermentation raw material from blocking steam vent.

Further, the fermentation tank can be replaced fermentation cell body, and the air-breather is to equally suitable using trough type fermentation With airway only need to being arranged on to fermentation tank body sidewall, below bacteria residue heap body.

The beneficial effects of the utility model are：The utility model passes through special in fermentation tank or fermentation tank body indoor design The breather line of door, and be both needed to according to the heap body of different depth in bacteria residue composting fermentation process to provide oxygen, specially devise and be in More discharge ducts being spirally distributed, the structure can guarantee that the effect for being passed through oxygen in each depth, without Large-scale fertilizer turning-over machine is lodged to carry out turning over fertile processing；The utility model possesses that ventilation is fast, compost fermentation effect is good, and good economy performance etc. is excellent Point.
