Abstract
The invention relates to use of a helical squeezing dehydrating machine, in particular to application of a helical squeezing dehydrating machine to treatment of kitchen waste. During treatment of the kitchen waste, the kitchen waste is separated into a soup part and a dry residue part by using the helical squeezing dehydrating machine; the soup part can be taken as a culture medium of biological bacteria; the soup part can be used for making ethanol and fertilizers after oil removing and dehydration; the obtained dry residue part is buried directly, so that pollution of underground water is avoided.
Description
Technical field
The present invention relates to the application in changing food waste process of the purposes of spiral pressing dehydrator, particularly spiral pressing dehydrator.
Background technology
Changing food waste, be commonly called as hogwash, it is the sanitary waste that food and beverage enterprise and resident are formed in personal consumption process, its main component comprises rice and flours food residues, vegetables, vegetable and animals oils, meat bone, wooden chopsticks, plastics thing etc., chemically on composition, there are starch, cellulose, protein, lipid and inorganic salts.Changing food waste very easily rots, and distributes stench, and spread germs and virus, its proterties and smell all can make a very bad impression to environmental sanitation, and easily grow the harmful substance such as pathogenic microorganism, mycotoxin.Changing food waste content of organics is high, recyclability is good, there is obvious resource characteristics and pollutant characteristic, minimizing, resource, innoxious use are carried out to it, front sorting is crucial, inorganic matter (i.e. solid) sorting in the liquid object such as the water in changing food waste, grease, organic matter and changing food waste is separated, all extremely important to follow-up landfill, production biogas, ethanol, biological bacteria, fertilizer etc.
At present, in changing food waste, solid is generally adopt the screen utensil with many eyelets to carry out with being separated of liquid object, adopt such screen utensil not only troublesome poeration effort, and can only be the solid on surface and being separated between liquid object, solid after separation still contains a large amount of moisture, the process to changing food waste solid in unfavorable like this subsequent handling.And changing food waste is all transport directly to treatment plant after food and beverage enterprise collects at present, and because changing food waste contains the moisture content of 80-90%, transport difficult, increase larger cost of transportation, therefore is unfavorable for the all-round popularization of changing food waste process.
Spiral pressing dehydrator is also screw extrusion dewaterer, it is widely used in the dewatering operation before high humidity grain slag dry materials, as dehydration and the humid control of vinasse, pomace, the dregs of a decoction, manioc waste etc., can in material separating about 20% moisture, greatly alleviate the burden of drying machine, it is requisite treatment facility before high moisture material drying, material after dehydration directly can enter drying equipment, considerably reduce energy consumption for drying, at present, spiral pressing dehydrator except such use, there are no other purposes.
Summary of the invention
The object of this invention is to provide the novelty teabag of spiral pressing dehydrator, be to provide the application of spiral pressing dehydrator in changing food waste process specifically, make the changing food waste after spiral pressing dehydrator process, its solid can thoroughly be separated with liquid object, reduces the water content in solid.
Spiral pressing dehydrator of the present invention is made up of frame, transmission system, hydraulic system, electrical apparatus control system, feeding part, press sections and guard shield etc., screw shaft in transmission system comprises feed auger, propelling worm and extrusion spiral three part, by motor through belt pulley, gear reduction box driven rotary, the squeezing of material is realized by squeezing screen drum and material stopping device, the stop being pressed through material outlet of material is compeled door and is realized with extruding screen drum, and the rotating speed of screw shaft controls by frequency converter.
The middle part of spiral pressing dehydrator is provided with material feeding box, worry plate is provided with in material feeding box, material is sent in material feeding box, namely part moisture content is had to be flowed out voluntarily by filter plate, the liquid state organic matter squeezed out through screw shaft then flows to water dish by the sieve aperture on screen drum, flowed out by the fluid hole on water dish, such as the materials such as bone, wooden chopsticks, plastics, pottery, metal of the solids after squeezing are gone out by the urgent door row of screen drum end again.
Hydraulic system directly drives plunger oil pump to provide pressure oil (hydraulic oil) by motor by shaft coupling, by the height of adjustable-pressure overflow valve hydraulic control system pressure, and the manually flow direction of reversal valve hydraulic control system pressure oil.Oil cylinder is fixed on the supporting base of spiral pressing dehydrator afterbody, and piston rod and the material outlet of hydraulic cylinder stop that compeling door is connected, and by the size of the extension and contraction control material outlet of piston rod, the dry wet of deslagging can control as requested at any time.
Spiral pressing dehydrator is when processing changing food waste, that changing food waste is put into material feeding box, changing food waste is by the squeezing of screw shaft, the soup slurry squeezed out flows to water dish by the sieve aperture on screen drum, flowed out by the fluid hole on water dish again, the solids such as the bone in changing food waste, wooden chopsticks, plastics are then squeezed into dry slag, are gone out by the urgent door row of screen drum end.
The soup slurry part that kitchen waste spiral pressing dehydrator squeezes out can be used for the culture medium doing biological bacteria, and is used for making ethanol, fertilizer etc. after also can dewatering, and the dry slag part obtained then directly can carry out landfill.
Spiral pressing dehydrator is used for the process of changing food waste, changing food waste can be made easily and thoroughly to be separated into soup slurry part and dry slag part, thus realize solid in changing food waste and be separated with the thorough of liquid object, and in solid, water content is low.Soup slurry part can be used for the culture medium doing biological bacteria, and can make ethanol, fertilizer, biogas etc. after also can dewatering, dry slag part then directly can carry out landfill, thus changing food waste is turned waste into wealth, and obtains fully useful recycling.And dry slag part is carried out landfill, owing to not being with soup, grease and puke, therefore the pollution of underground water can not be caused.Therefore can thoroughly the solid of changing food waste be separated with liquid object by spiral pressing dehydrator, effectively sorting before changing food waste and the process in later stage can be separated, be convenient to the transport of changing food waste, be conducive to the all-round popularization of changing food waste process.Therefore the present invention be realize the minimizing of changing food waste, resource, innoxious use lay the first stone.
Detailed description of the invention
In changing food waste process, use the YZ20 spiral pressing dehydrator manufactured by Zhong Qing Machinery Co., Ltd. of Xinxiang City, changing food waste is separated into solid portion and liquid part.
Its processing procedure is:
Changing food waste is put into the material feeding box of YZ20 spiral pressing dehydrator, changing food waste is by the squeezing of screw shaft, the liquid parts such as the soup squeezed out, grease and puke flow to water dish by the sieve aperture on screen drum, flowed out by the fluid hole on water dish again, the solids such as the bone in changing food waste, wooden chopsticks, plastics are then squeezed into dry slag, are gone out by the urgent door row of screen drum end.Liquid part can be used for producing biogas, fertilizer, ethanol and biological bacteria etc. after oil removing dehydration, and the dry slag waste part obtained then directly can carry out landfill, sewage again through membrane bioreactor advanced treating after the qualified discharge of liquid part after oil removing dehydration.
