Description
Technical field
The utility model relates to a kind of butyl rubber extruding-desiccation machine, belongs to the main production equipments of petroleum chemical industry synthetic rubber post processing processing.
Background technology
butyl rubber is chain macromolecule compound, by isobutene and the synthetic copolymer of a small amount of isoprene monomer, because distribution and the arrangement architecture of molecule in its strand are more special, thereby make butyl rubber have best air-tightness, namely very little air penetrability is much smaller than natural rubber, heat-resistant aging can use in 100 ℃ of air for a long time, good damping and amortization absorbs vibration and impact energy and chemical stability most inorganic acids and organic acid is all had good corrosion resistance and the effect of alkaline-resisting and ammonia and the good characteristics such as electric edge, therefore, butyl rubber comprises after halogenation modification at the tubeless inner liner of automobile, the inner tube of a tyre, Medical bottle stopper, building waterproof layer, the industries such as insulating materials electric wire obtain a wide range of applications.
Butyl rubber on the extrusion dehydration operation of aftertreatment technology owing to there being moisture micelle bad adhesion, micelle loose especially and with the characteristics such as other elastomeric compatibilities are relatively poor, therefore be difficult for charging when general synthetic rubber extrusion dehydration machined, cause difficulty, dehydration does not reach the index request of discharge moisture content 8%-12%, discharge occurs and " alter " phenomenon rare, can't satisfy the charging index request of subsequent processing extrusion expansion drying machine.
The utility model content
The purpose of this utility model is to provide a kind of easy charging, makes and press conveniently, solve the butyl rubber extruding-desiccation machine that discharge " is altered rare " and reached discharge moisture content index request.
The technical solution adopted in the utility model is: a kind of butyl rubber extruding-desiccation machine, comprise squeezing dehydration device and drive unit, the housing that described squeezing dehydration device adopts loading hopper, conic tube, one section straight barrel and the section of being connected straight barrel to connect successively, housing support and bearing bracket, be provided with screw rod in housing, be provided with the template pressure regulating device of regulating sizing material pressure in the housing exit, be provided with shear screw, thermometric screw, pressure measurement screw and draining sieve on housing, be provided with the first water receiving case and the second water receiving case in lower housing portion; Described drive unit adopts motor, shaft coupling to be connected with gear reduction unit and to connect; Described squeezing dehydration device and drive unit adopt terminal pad to link together, and are arranged on a public base; Described screw rod is connected with the output shaft of gear reduction unit.
Described screw rod employing pitch diminishes gradually, spiral is interrupted and the structure of removal twin-feed spiral.
Described draining sieve is arranged on the below of one section straight barrel and two sections straight barrels.
The beneficial effects of the utility model are: this butyl rubber extruding-desiccation machine comprises squeezing dehydration device and drive unit, be provided with screw rod in the housing of squeezing dehydration device, be provided with the template pressure regulating device in the housing exit, be provided with shear screw, thermometric screw, pressure measurement screw and draining sieve on housing.Drive unit adopts motor, shaft coupling to be connected with gear reduction unit and to connect, and screw rod is connected with the output shaft of gear reduction unit.This dewaterer has solved the moisture micelle of butyl rubber because of bad adhesion, the loose especially difficult feed that causes, makes to press to be difficult for a series of difficult problems that discharge " is altered rare " and moisture content can not be up to standard.

The specific embodiment
Fig. 1 shows a kind of structure of butyl rubber extruding-desiccation machine.In figure, the butyl rubber extruding-desiccation machine comprises squeezing dehydration device and drive unit.The housing that squeezing dehydration device adopts loading hopper 5, conic tube 7, one section straight barrel 8 and the section of being connected straight barrel 10 to connect successively, housing supports with support 14 and carriage 19, be provided with screw rod 6 in housing, screw rod 6 employing pitch diminish gradually, spiral is interrupted and the structure of removal twin-feed spiral.Be provided with the template pressure regulating device 11 of regulating sizing material pressure in the housing exit, be provided with shear screw 9, thermometric screw 12, pressure measurement screw 13 and draining sieve 15 on housing, draining sieve 15 is arranged on the below of one section straight barrel 8 and two sections straight barrels 10.Be provided with the first water receiving case 16 and the second water receiving case 17 in lower housing portion.Drive unit adopts motor 1, shaft coupling 2 to be connected with gear reduction unit to connect successively; Squeezing dehydration device and drive unit adopt terminal pad 4 to link together, and are arranged on a public base 20.Screw rod 16 is connected with the output shaft of gear reduction unit 3.
During work, start motor 1, drive screw rod 6 rotations through shaft coupling 2 and gear reduction unit 3, the moisture micelle of butyl rubber adds through loading hopper 5, promoted to flow forward by screw rod 6, and the characteristics that adopt pitch to diminish gradually due to screw rod 6, increased the material feeding power of material, make charging smooth, be provided with Waste water screen 18 simultaneously below loading hopper 5, the part free water can enter from here water receiving case 17 and reclaim.Under the continuation of screw rod 6 promoted, sizing material entered and is subject to powerful compression in conic tube 7, the part free water was sieved by draining enter water receiving case 16 and reclaim.after sizing material enters one section straight barrel 8 and two sections straight barrels 10, because pitch continues to diminish, increased compression ratio, add that spiral is interrupted, acting in conjunction and the dependence template pressure regulating device of shear screw and straight barrel inner surface resistance glue groove are suitably regulated sizing material pressure in cylindrical shell, thereby further remove unnecessary moisture, discharge and reclaim by draining sieve 15, the sizing material temperature also has suitable raising simultaneously, from the nib of template, sizing material is evenly discharged at last, due to the sizing material pressure drop, slight evaporative cooling phenomenon appears in sizing material, finally make the moisture content of sizing material reach qualified index.
