A kind of pretreating process of the processing kitchen garbage of kitchen garbage pretreatment system using described in the present embodiment：
Kitchen garbage receives fortune vehicle 14 and pours receiving hopper 2 by the kitchen garbage transported back and is received, and 2 surrounding of receiving hopper has draining strainer
3, kitchen garbage waste liquid flows to the waste collection pond 102 of lower section through draining strainer 3, then by filtrate elevator pump 7 by waste collection pond
Waste liquid in 102 is pumped into follow-up existing water-oil separating processing unit.2 bottom of receiving hopper is equipped with metal collection box 4, metal collection
There is magnet arrangement 5 in box 4, is collected the metallics fallen first by gravity by magnetic force, it is periodically clear to metal collection box 4
Reason.The material in receiving hopper 2 is delivered to broken pulping device 11 by grab bucket 9, such broken pulping device 11 is by the inner
Portion is equipped with wearing plate and nearly 2 tons of mill ball 1101, is not afraid of the influence of the impurity such as metal and plastics, is crushed in pulping device 11
Kitchen garbage is broken into slurry form by these mill balls 1101, and the impurity such as metal, plastics, chopsticks are pounded into the bulk of very little, with
The inorganic impurity of kitchen garbage slurry and fritter discharge afterwards is crushed pulping device 11.The kitchen rubbish come out from broken pulping device 11
The inorganic impurity of rubbish slurry and fritter is admitted in the filter screen 1201 squeezed in exclusion device 12, is squeezed exclusion device 12 and is passed through
For hydraulic plate 1203 by 1204 the lowermost accumulation of impurities area 1209 of inorganic impurity indentation shell, kitchen garbage slurry is extruded filtering
Net 1201 enters slurry storage layer (namely annular space 1208), by screw pump by the slurry of slurry storage layer (namely annular space 1208)
Subsequent processing units are pumped into, the impurity for squeezing 12 lower part of exclusion device is periodically cleared up through impurity outlet 1207, realizes meal
Kitchen rubbish is detached with impurity such as metal, plastics, the wooden chopsticks.
Wherein, kitchen garbage enters after receiving hopper the principle that different impurities are detached by metal collection box and magnet arrangement
For：Metallics, other solid impurities in rubbish fall under gravity into receiving hopper 2 and metal collection box 4, are falling
Cheng Zhong, metallics in rubbish is since density is big compared with other solid impurity density, therefore it drops to prior to other solid impurities
The bottom of receiving hopper 2, and the bottommost by the magnetic-adsorption of magnet arrangement 5 in metal collection box 4, other solid impurities
Then fall into metal collection box 4 and receiving hopper 2.
Using the pretreatment unit and technique pretreatment kitchen garbage described in the present embodiment, kitchen waste draining is except heavy miscellaneous
Device processing, draining effect are good；Through draining except treated that kitchen garbage enters is crushed pulping device for the miscellaneous device of weight, in broken system
The ground ball of solid impurity in paddle device in kitchen garbage be ground into it is small block-shaped, later from be crushed paddle device processed in out
Slurry and small blocky impurity enter together squeezes exclusion device, and since the size that solid impurity is ground is more uniform, hydraulic plate is applied
Power is more uniform, good to the squeezing effect of solid impurity, and after squeezing removal of impurities process, all solids impurity is trapped within tubular
Filter screen in, solid impurity removal rate can reach 100%, and slurry is extruded by filter screen, realize kitchen garbage slurry with
The separation of inorganic impurity.
Embodiment 2
