Description
Technical field
The utility model relates to chemical field, specifically refers to the production line of TPE.
Background technology
Thermoplastic elastomer (TPE) (Thermoplastic Elastomer, TPE) be a kind of high resiliency with rubber, high strength, high resilience, but the material that there is again the feature of injection molding, there is environment-protecting asepsis safety, hardness range is wide, there is good physical property, thereby looked at by the increasing industry parent of institute, its preparation method is generally after raw material is mixed, through double screw extruder at present, then carry out granulation, wherein producing the uniformity of particle and the content of moisture on surface is a large index of the quality of production.
The utility model content
The purpose of this utility model is to provide a kind of uniformity that can meet particle, can also control the production line for TPE of its surface moisture simultaneously.
In order to realize this purpose, the utility model has adopted following technical scheme:
The production line of a kind of TPE, comprise proportioner, extrusion device, pelleter, cooling system, dewater unit and packing device, described extrusion device comprises double screw extruder and single screw extrusion machine, described proportioner is with agitating device, described proportioner is placed in the top of the charging aperture of described double screw extruder, the discharging opening of described double screw extruder is placed in the top of the charging aperture of described single screw extrusion machine, the discharging opening of described single screw extrusion machine is connected with the charging aperture of pelleter, the discharging opening of pelleter is connected with described dewater unit by cooling pipe, described cooling pipe is placed in described cooling system, described dewater unit is centrifugal dehydrator, also be provided with screening plant and drying device between described centrifugal dehydrator and described packing device, described centrifugal dehydrator is connected with described screening plant by conveyance conduit, described screening plant is connected with described drying device by conveying fan, and described drying device is connected with described packing device by conveying device.
Further, described proportioner is low speed Horizontal stirring bucket.
Preferably, described screening plant is vibratory sieve.
As preferred version, described drying device is the dry agitator with temperature incubation function.
Further, the utility model also is provided with recovery bin, and this recovery bin is connected with described vibratory sieve, and described recovery bin is connected with described proportioner.
Originally be that utility model is combined twin-screw complementation with single screw rod advantage, by the twin-screw forced conveyance, efficiently plastify and mixingly disperse with shearing, reflux without the head back pressure, avoided high shear overheated; Single screw rod high pressure is extruded; but low speed is low, shear; avoided equally overheated contradiction; adopt the agitator batching of using low speed in batching; phase higher speed bucket stirs more even; be difficult for producing frictional heat; simultaneously; the particle temperature that raw material is produced after pelleter is higher; reduce temperature through cooling system, though the water-cooled material grain of process through the most of moisture content of centrifugal dehydration function filtering, expects that also can residually there be a small amount of moisture content on the grain surface; dry product by the agitator with temperature incubation function again, so just can make the every physical property of product of same batch more aligned.
The accompanying drawing explanation
Accompanying drawing 1 is structure chart of the present utility model.
The specific embodiment
Describe the utility model in detail referring now to accompanying drawing.
