Processing system.
Background technique
Since the eating habit in China and garbage classification, resource reclaim consciousness are weaker, impurity is more in kitchen garbage.Mix
There are a large amount of plastics, disposable packaging, tableware or even some house refuses, building waste that can also mix wherein.Meal at present
Kitchen rubbish needs to carry out separation of solid and liquid pretreatment before comprehensive utilization of resources, and its purpose is to the maximum extent will be in kitchen
Oil is removed and mentioned after being separated by solid-liquid separation to inorganic impurity, guarantees that the organic matter in kitchen is separated as far as possible into subsequent fermentation ring
Section.
At present China's mainstream kitchen garbage pretreatment core process be will be in kitchen garbage by big part screening installation
Bulky Waste sieves away, carries out cracking and sorting by one or more levels cracking and sorting machine later, subsequent using desanding and to remove
Heterocycle section, it is final that qualified slurry is made, so that subsequent boiling mentions needed for oil.This pretreating process has the following problems

(2) cracking and sorting equipment energy consumption is big, high failure rate.Due to having infiltrated a large amount of house refuse in kitchen garbage, and
It cannot preferably be removed in front-end processing link, therefore bigger to the abrasion of grinder hammerhead, strong impact is but also broken
Broken owner's axis service life reduction, cracking hammer head and main shaft high frequency of replacement, seriously affect normal operation.Meanwhile broken is one
The technique that kind consumes energy very much, causes the increase of processing cost；
(3) it is inorganic be mingled with it is more.The separation of organic matter is wrapped in the containers such as polybag, box and bottle mainly by being crushed
In organic kitchen separated under the fragmentation of hammer leaf.Glass, ceramics and brick but during broken, in kitchen
It is watt equal to be also broken, a large amount of blocky and particulate inorganic impurity, such as sand, cullet, broken ceramics are produced, after this just gives
Continuous processing links, which are brought, to be seriously affected, in order to remove these impurity, it has to add desanding device.
(4) organic matter loss is larger.The acquisition of organic matter is however a part of organic during broken mainly by broken
Matter can be lost；Big part sorting link before breaking can also lose part organic matter；For desanding and fiber-like impurity, increase
Screw extruder, removal effect is preferable, but organic matter largely loses.
