Description
Technical field
The utility model belongs to the fermentation equipment field, is applied to organic materialss such as various fertilizer, feed and food and carries out in the aerobic fermentation process, is specifically related to a kind ofly when fermentation materials is turned, and realizes the device to material forced ventilation oxygenation operation.
Background technology
In the daily production of enterprise, when organic materialss such as fertilizer, feed and food are carried out aerobic fermentation, fresh air can't enter material inside in the process owing to turning, have only the material of being translated into the stockpile surface to have an opportunity to touch fresh air, and inner material can't touch fresh air at all, so very undesirable to the aeration-cooling and oxygenation effect of fermentation materials.Can not get competent oxygen supply owing to participate in the aerobic microbiological of fermentation, and the fermentation materials internal heat can't fully exchange with extraneous air, it is inner because the damp and hot water vapor that high temperature forms can not get in time fully evaporation, the material internal temperature can not effectively be regulated fast, make material can not often be in best fermentation state, cause the material fermentation period long, the turnover rate and the utilization ratio of fermentation plant have been reduced, strengthened the investment of enterprise to fermentation plant facility and fermentation equipment, also increase the energy consumption in the fermentation production process simultaneously, influenced economic benefit of enterprises.
In order to improve existing fertilizer, the ventilation situation of the aerobic fermentation of feed and food, some have designed the stirring ventilation installation of various structures in recent years, Chinese patent for example: 1, application number: 200620030783.9, name is called: spiral screening apparatus ventilation plant, relate to a kind of spiral screening apparatus ventilation plant of realizing when fermentation materials is turned the forced ventilation operation of material, comprise the cored screw axle that is located on the spiral screening apparatus frame, on the cored screw axle, have the hole, air feed equipment is connected with the cored screw axle by air line, have the fermentation materials forced ventilation, improve the fermentation condition of material, strengthen ferment effect, shorten the advantage of fermentation period.Another part Chinese patent: 2, application number: 200720107020.4, name is called: a kind of organic refuse horizontal multiple-chamber processing unit discloses a kind of organic refuse horizontal multiple-chamber processing unit.It is made up of fermentation unit, whipping appts, feeding device, heating unit, ventilation plant and leachate recycle device.This device utilizes a plurality of horizontal fermentation cabin that organic waste is carried out biological fermentation, by spiral propeller convey materials in enclosed space, and utilizes whipping appts to assist cloth, and the height of treatment unit is greatly reduced.Simultaneously, utilize the acting in conjunction of heating unit, ventilation plant, leachate recycle device and whipping appts, provide fermentation required optimum condition.Repacking is put and can in the short cycle organic waste be converted into harmless organic fertilizer, realizes the recycling treatment of rubbish.3, Chinese patent application number: 02241094.5 also discloses a kind of fermented storehouse of the rubbish that is used to handle domestic refuse, include fermentation warehouse and the feeding conveyor that is configured in above the warehouse, bulkhead is arranged in each both sides, warehouse bottom, unit of its fermentation cabin, and blast inlet under being tilted to is set, two adjacent inclination bulkheads constitute a trilateral vented cavity, and the ventilation opening that links to each other with outer air feed machine is separately positioned on central authorities at the bottom of each vented cavity; Be respectively arranged with discharge port in the bottom of each unit warehouse and assemble spiral discharging machine respectively, be provided with in the one side with each discharging machine phase configuration and ooze drop liquid irrigation canals and ditches, opposite side disposes the total discharging spiral conveyor of fermentation cabin.This fermentation cabin adopts " V " shape storehouse bottom structure, and be tilted to blast inlet down and have storehouse, the unit spiral discharging machine and the total discharging spiral conveyor of fermentation cabin of oozing drop liquid discharge function with disposing at the bottom of " V " shape storehouse being provided with on the inclination bulkhead, make in the fermentation cabin heap layer ooze the discharge of drop liquid and the air feed oxygen supply is stable, evenly, reliable, refuse treatment is effective, the operating automation degree height.
From above-mentioned disclosed document, recognize, when organic materialss such as fertilizer, feed and food are carried out aerobic fermentation, generally be to carry out in fermentation cabin, be to provide air that the fermented organic material is forced stirring, ventilation and oxygenation with blower fan or air compressor in the hopper of fermentation cabin, make fresh air enter material inside, introduce heating unit and the ventilation plant coupling that has in the document 2, introduce the blast inlet that is provided with on the inclination bulkhead that has under being tilted in the document 3.But above-mentioned stirring, ventilator are subjected to the influence and the restriction of its structure and principle of work, and material just stirs up and down in the original place, can not make material effectively aerobic, need heat, and have also increased the energy consumption in the fermentation production process.Document 1 proposes to have installed additional forced ventilation device on stack turner, that is: by being arranged on the cored screw axle on the spiral screening apparatus frame, perforate on the cored screw axle, air feed equipment is connected with the cored screw axle by air line, when turning operation, the cored screw axle rotates under the driving of screening apparatus transmission rig, material is turned, air feeder starts simultaneously, air communication is crossed air line and is entered the cored screw axle, as if the production well that passes on the cored screw axle axial wall enters in the fermentation materials, and this structure can have been strengthened ventilation, but do not have actual effect substantially in production application.Because be subjected to the restriction of the screw shaft diameter of axle, in order to guarantee the physical strength of screw shaft, passing the air vent aperture of screw shaft can only open very for a short time, probably between 10-15mm, therefore air feed equipment is very little by the air pressure that this pore infeeds the cored screw axle, flow is also very little, just can't permeate and penetrate material at all, still not reach for the purpose of fermentation materials forced ventilation oxygenation.Therefore, increase this effect of installing the back screening apparatus and almost do not obtain substantial improvement.
