Description

A kind of solid waste crushes high-efficient treatment device
Technical field
The present invention relates to environmental technology field, specially a kind of solid waste crushes high-efficient treatment device.
Background technology
Fixed-end forces, the treatment of full name solid waste, the treatment of solid waste typically refer to physics, chemistry, biology, Materialization and biochemical method solid waste is converted into be suitable to transport, store, using or disposal process, solid waste treatment Target is innoxious, minimizing, resource.It is believed that solid waste is one kind that disposal is most difficult in " three wastes ", because it contains Some compositions are considerably complicated, also thousand change ten thousand of its physical behavior (volume, mobility, uniformity, degree of grinding, moisture content, calorific value etc.) Change, to reach above-mentioned " innoxious, minimizing, resource " target can run into sizable trouble, general preventing and treating solid waste is dirty Dyeing method is to control its yield first, for example, progressively Reform of Urban fuel structure (including civilian industry) control factory is former The consumption of material, quota improves the service life of product, improves rate of recovery of waste product etc.;Next to that carry out comprehensive utilization, solid Waste is treated as resource and the energy, turns into final state solid waste after tangible unavailable then compressed and nontoxic treatment, so Fill and sink sea again afterwards, the main method for using is including compacting, broken, sorting, solidification, burning, biological treatment etc. at present.
Crushing is a kind of common method in fixed-end forces, and common fixed-end forces device crushing effect is not ideal enough, not Solid waste to be processed can will be needed to be crushed completely, in the patent No. is the Chinese patent of CN205551049U, it is noted that A kind of " fixed-end forces equipment ", the liquid collecting box in equipment is connected including back taper collecting chamber with back taper collecting chamber bottom Vertical chamber and the annular liquid storage cylinder that is connected with vertical bottom of chamber end, annular liquid storage cylinder bottom end side wall is provided with leakage fluid dram, leakage fluid dram Inside it is provided with out liquid switch.Fixed-end forces equipment of the present invention can be pre-processed to rubbish, be concentrated after waste liquid is leached Treatment, and discarded object is blended and tamped, be conducive to recycling scrap concrete, the storage of house refuse can be reduced Space;The structure setting of liquid collecting box can conveniently be collected and store filtrate, and convenient recovery less discarded object containing filtrate oozes Go out liquid, and the setting in cone-shaped collection chamber facilitates follow-up cleaning after garbage disposal to fixed-end forces equipment, moreover it is possible to make fixed-end forces Equipment do not incline, it is more stable to process discarded object, has the advantages that environmental protection, easy cleaning.But the equipment mentioned in the patent is crushed Effect is not ideal enough, it is impossible to which solid waste is crushed to satisfactory particle diameter by guarantee, so as to the compacting to after and transport behaviour Certain influence is brought, the solid waste volume that solid waste is far crushed completely for failing to crush completely is big, so as to result in Unnecessary space waste, causes operating efficiency to reduce.
