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
Kitchen garbage draining described in the present embodiment is substantially the same manner as Example 1 except miscellaneous device is weighed, the difference is that：
As shown in fig. 6, the magnet arrangement 5 is the magnetic sheet that upper surface is the conical surface, the conical surface can have more relative to plane
Big contact area improves attraction power of the magnet arrangement 5 to metal impurities.
In order not to make metal impurities flock together absorption, 5 edge of magnet arrangement and metal collection box 4 are arranged to the company of being slidingly sealed
The form connect is fixedly connected between 5 bottom of magnet arrangement and 4 bottom of metal collection box by spring 8, and magnet arrangement 5 is in metal
Can have under the collision of impurity etc. it is slight teetertotter so that metal impurities are uniformly contacted with magnet arrangement 5, avoid metal miscellaneous
Matter flocks together absorption.
The pretreating process of processing kitchen garbage described in the present embodiment is substantially the same manner as Example 1.
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；After broken pulping process, kitchen garbage is made into slurry form, metal, plastics, wood
The impurity such as chopsticks are made into small block-shaped；Together from the kitchen garbage slurry and small blocky impurity being crushed in paddle device processed out later
Into exclusion device is squeezed, since the size that solid impurity is ground is more uniform, hydraulic plate force is more uniform, to solid impurity
Squeezing effect is good, and after squeezing removal of impurities process, all solids impurity is trapped in the filter screen of tubular, and solid impurity is gone
Except rate can reach 100%, slurry is extruded by filter screen, realizes the separation of kitchen garbage slurry and inorganic impurity.
Embodiment 3
Kitchen garbage draining described in the present embodiment is substantially the same manner as Example 2 except miscellaneous device is weighed, the difference is that：
As shown in fig. 7, it is wavy magnetic sheet that the magnet arrangement 5, which is upper surface, it is wavy to increase magnet and meal
The contact area of metal impurities in the rubbish of kitchen.
5 edge of the magnet arrangement is slidably and sealingly connected with metal collection box 4,5 bottom of magnet arrangement and metal collection box 4
It is fixedly connected by spring 8 between bottom.This setup, in kitchen garbage dropping process, along with kitchen garbage
It falls, magnet arrangement 5 can there are one slight to move up and down in metal collection box 4, to increase metal impurities and magnet arrangement 5
Contact area, make metal impurities be unlikely to be deposited in some point of magnet arrangement or position.
The pretreating process of processing kitchen garbage described in the present embodiment is substantially the same manner as Example 1.
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；After broken pulping process, kitchen garbage is made into slurry form, metal, plastics, wood
The impurity such as chopsticks are made into small block-shaped；Together from the kitchen garbage slurry and small blocky impurity being crushed in paddle device processed out later
Into exclusion device is squeezed, since the size that solid impurity is ground is more uniform, hydraulic plate force is more uniform, to solid impurity
Squeezing effect is good, and after squeezing removal of impurities process, all solids impurity is trapped in the filter screen of tubular, and solid impurity is gone
Except rate can reach 100%, slurry is extruded by filter screen, realizes the separation of kitchen garbage slurry and inorganic impurity.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
