The kitchen waste pretreatment unit is simple in structure, low in manufacture price and practical, can effectively sort out non-degradable substances such as plastics and metal parts in kitchen wastes, crushes organic matters in the kitchen wastes into coarse slurry, and creates pre-conditions for further fine and even slurry preparing, heavy metal removing, dioxin degrading, mineralization fermenting and microbial organic fertilizer producing.

Description

Changing food waste preliminary treatment unit

Technical field

The utility model relates to a kind of screening installation---changing food waste preliminary treatment unit that utilizes changing food waste to make organic fertilizer.

Background technology

China produces nearly hundred million tons of changing food wastes at present per year, and along with the quickening of Process of Urbanization, urban population sharply expands, and estimates that changing food waste every year also will be with 30% speed increment.Changing food waste has the double grading of refuse and resource, how to dispose, and has become the important topic of pendulum in face of people.Because the special nature of changing food waste, burning disposal can produce a large amount of pernicious gases; Directly its water content of landfill is high produces a large amount of percolates and polluted underground water easily.The at present processing of changing food waste mainly is to produce feed, fertilizer, biogas and diesel oil.Owing to contain various animal meats in the changing food waste, if Fodder making, there is the homology risk, moreover with not rejecting heavy metal, not decomposing the changing food waste Fodder making of bioxin, enter human body with the form of biological chain by the animal meat just for heavy metal, bioxin chance is provided, sow the seeds of trouble in the future; Carry out producing diesel oil after the water-oil separating through Anaerobic Treatment production biogas or with changing food waste, all have the problem that investment is large, cost is high; Utilize changing food waste to produce fertilizer direction enemy, but take at present aerobic compost to produce the method for fertilizer, do not reject the contained heavy metal ion of plant and animal residues in the changing food waste, do not have to decompose to fry in shallow oil to fry and fry the contained De dioxins materials of remnant food, there are serious quality problems in fertilizer, and fertilizer efficiency is poor, is vetoed by market, is difficult to promote.We reject the method that heavy metal decomposes bioxin mineral fermentation composting by the changing food waste of invention, have solved the problems referred to above.

Changing food waste be not the imagination in so simple, except accounting for the water about 85% and accounting for 13% the organic matter, account in addition 0.3% waste plastics, 0.1% is difficult to thigh, gigot bone, the fish fishbone into machine, the meat extract that 1% viscosity is very strong also has beer bottle, bottle cap, broken glass cup, disk, wooden dipper spoon etc.If in addition sorting will not have influence on integral production technique.Therefore, adopt and reject the method that heavy metal decomposes bioxin mineral fermentation composting, the preliminary treatment of changing food waste is that sorting is exactly indispensable link.

The utility model content

The purpose of this utility model is a kind of equipment that changing food waste non-degradable thing is sorted out of development, so that slurrying and then rejecting heavy metal, separate dissolved and hot fermentation biology are engulfed the decomposition bioxin, makes microbial organic fertilizer.

Principle of the present utility model; (1) changing food waste contains that grease is many, viscosity is large, therefore needs flushing to scatter before sieving, and breaks up so douche can is sent first in design to.Douche can is selected variable-frequency motor, and rotating speed can be adjusted as required, is transferred to per minute 45 right side of turning left.Douche can internal diameter 〉=80cm installs totally 8 of 10cm * 10cm * 10cm rake tooths in the bucket, be used for stirring the changing food waste of moisture content about 85%; (2) although the changing food waste complicated component, can be divided into screenings (directly defibrination) and oversize spare (again sorting) but sieve, so design sieves, its diameter gets final product than the large 40cm of douche can, be provided with spiral propeller in the sieve, mesh size 15mm prevents that beer bottle cap from leaking down; (3) oversize has metal objects, plastics, the bowl dish of breaking, bone etc., so design Belt Conveying magnetic separator can reclaim metal objects by magnetic separation, and pick out other big article at its conveyer belt; (4) need to clean better recycling because of wherein waste plastics, so design plastic cleaning pond, Chi Shuizhong contains washing powder or NaOH, is convenient to decontamination and goes stain; (5) organic materials that sinks such as bone needs brokenly just be convenient to system shadowboxing pulp grinder, so select Xiao Xing E formula disintegrating machine, the broken mixing with screenings afterwards is drawn into shadowboxing pulp grinder processed and wears into the homogenate of 50-80 order.

Architectural feature of the present utility model: changing food waste preliminary treatment unit is received bucket, kiln basin, is taken out pulp grinder and form by douche can, sieves, Belt Conveying magnetic separator, plastic cleaning pond, E formula disintegrating machine, metalwork, its architectural feature is: douche can 1 is close to sieves 2, and lace is carried the conveyer belt of magnetic separator 3, this machine magnet drum below is provided with metalwork and receives bucket 6, and the place ahead connects plastic cleaning pond 4; Little type E formula disintegrating machine 5 is installed on 4 next doors, plastic cleaning pond, and binder stock tank 7 is equipped with in the pond and takes out pulp grinder 8.

The beneficial effects of the utility model: changing food waste preliminary treatment unit is simple in structure, cost is low, but very practical, can effectively sub-elect the non-degradable things such as plastics in the changing food waste, metalwork, and the changing food waste organic matter is broken into coarse fodder slurry, for further making thin homogenate, reject heavy metal, decompose bioxin, the mineral fermentation, making microbial organic fertilizer and created precondition.

The specific embodiment

Changing food waste is directly put douche can 1 into after entering factory, starts its variable-frequency motor, and rotating speed is transferred to per minute 45 right side of turning left, and automatically breaks up flushing in douche can; Douche can is close to sieves 2, changing food waste after the flushing enters sieves and screens, screenings flows into kiln basin 7 with pulp-water, oversize falls into the conveyer belt of Belt Conveying magnetic separator 3, picking out big article in the conveying reclaims, the metal species object is automatically fallen into metalwork and receives bucket 6 (recovery) by this machine magnetic drum absorption behind the disengaging magnetic field; Waste or used plastics, large bone, fishbone etc. are sent to plastic cleaning pond 4, and Chi Shuizhong contains washing powder or NaOH, pulls waste plastics (recycling) after the cleaning out, and the water extraction that contains cleaning agent recycles; The precipitation material comprises that bone etc. after too small type E formula disintegrating machine 5 is pulverized, flows into kiln basin 7 in the pond, mixes with screenings, mixed slurry suction shadowboxing pulp grinder processed (next procedure) is regrinded into the 50-80 order makes homogenate by taking out pulp grinder 8.
