Abstract
Device, including hydraulic cylinder, motor, impact disc, helix tube, rotating disk, collection port, crushing bin inner casing, crushing bin shell and the insulation material being filled between inside and outside shell are ground the invention discloses a kind of waste or used plastics low-temperature impact.Described hydraulic cylinder is connected with impact disc, and motor reel is connected with rotating disk；By the way that by waste or used plastics, after low temperature environment cools down embrittlement, impact grinding is crushed, and realizes the low-temperature grinding of waste or used plastics；Utilize first to impact simultaneously and grind plastics afterwards, plastics can be made easily to crush, the problem of plastic shredding device energy consumption is big is solved, while plastics can be made fully to crush, environmental pollution, environment-friendly high-efficiency is not resulted in.
Description
Technical field
Field is crushed the invention belongs to waste or used plastics, and in particular to grind dress for a kind of waste or used plastics low-temperature impact
Put.
Background technology
The plastic disintegrator of prior art, mainly includes duroplasts pulverizer, strong plastic pulverizer and plastic pipe
Plastic crusher.These plastic crushers are typically made up of gyrator, blade, screen pack and transmission device, during work, are reclaimed back
The old plastics come are placed into feeding mouth, initially enter the steel impeller of rotation at a high speed, raw material is the friction of the impeller of machine, gear
In become incoherent, eventually become pulverulence.The plastic grain that existing waste or used plastics disintegrating apparatus is crushed is larger, power consumption
Height, the shortcomings of being unfavorable for secondary utilization.Therefore, designing a kind of waste or used plastics low-temperature impact and grinding device has important meaning
Justice.
The content of the invention
The purpose of the present invention is to use to impact attrition grinding technology after plastics low temperature brittleness, using plastics at low ambient temperatures
Brittle characteristic, is made its environment temperature be less than the brittle temperature of plastics, is destroyed using impulsive force under impact loading,
And then grind and obtain plastic powders.
In order to solve the above technical problems, device is ground the invention provides a kind of waste or used plastics low-temperature impact, including
Hydraulic cylinder, motor, impact disc, helix tube, rotating disk, collection port, crushing bin inner casing, crushing bin shell and it is filled in inside and outside
Insulation material between shell, the hydraulic cylinder and motor are outside crushing bin cover top portion, hydraulic cylinder and impact disc connection, impact
Disk is the solid hemi-spherical disk with raised blade, and the axle of motor and the center of rotating disk are connected, and rotating disk is to be provided with
The hollow hemispheric disk and the radius of impact disc that distance of center circle between 0.15mm circular apertures, Kong Yukong is 2mm are less than rotating disk
20~30mm of radius, collection port is below rotating disk, and helix tube is wrapped in the crushing bin inner casing between impact disc and rotating disk
Portion, the charging aperture of helix tube in bottom, discharging opening on top, direction of the cryogenic liquid in helix tube be from bottom to top, and
Filled polyurethane cellular insulant between crushing bin shell and crushing bin inner casing.
The device have the advantages that be effectively solve during waste or used plastics are crushed that plastic grain is larger and energy consumption compared with
Big the problem of.
Brief description of the drawings
Technical scheme is further described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic diagram that waste or used plastics low-temperature impact grinds device；
Fig. 2 is rotating disk two-dimensional representation；
Fig. 3 is rotating disk schematic three dimensional views；
Fig. 4 is impact disc two-dimensional representation；
Fig. 5 is impact disc schematic three dimensional views.
Embodiment
Plastics grind device by side door into plastics low-temperature impact, and helix tube 5 is passed through liquid nitrogen by bottom, passes through liquid
The vaporization of nitrogen, constructs the low temperature environment of crushing bin inner casing 2, and filled polyurethane steeps between crushing bin inner casing 2 and crushing bin shell 3
Foam 8, keeps constant low temperature.After the overall temperature of plastics reaches brittle temperature, the hydraulic cylinder 9 at top promotes impact disc 7 to impact
Plastics after embrittlement, plastics are changed into block, and after repeated stock 3 times, the rotating disk 4 that impact disc 7 is connected with the axle 6 of motor 10 is pasted
Close, rotated by rotating disk 4, impact disc 7 is fixed by hydraulic cylinder 9, realize grinding for unit of plastic.Treat that unit of plastic becomes powder
Afterwards, by falling on collection port 1 under the aperture in rotating disk 4, after collection, micron-sized plastic powders are obtained.
It should be noted last that, above embodiment is merely illustrative of the technical solution of the present invention and unrestricted,
Although the present invention is described in detail with reference to preferred embodiment, it will be understood by those within the art that, can be right
Technical scheme is modified or equivalent, and without departing from the spirit and scope of technical solution of the present invention, its is equal
It should cover among scope of the presently claimed invention.
