Description
Technical field
The invention belongs to rubber industry wastewater equipment technical field, and in particular to a kind of Plasticator spiral shell for various rubber industry wastewaters
Bar.
Background technology
With the fast development of China's rubber industry, waste old comprehensive utilization industry is also with surprising rapidity in development.
At present, in spent high molecular material, the proportion shared by waste old is only second to waste or used plastics.Because scrap rubber will not divide naturally
Solution so that the amount of scrap rubber is in close proximity to the volume of production of rubber, the accumulation of a large amount of waste rubber goodses and inappropriate process,
While causing the wasting of resources, also serious pollution environment is caused " black pollution ".Waste rubber goodses are carried out into proper treatment
And resource reclaim, can not only environmental protection, be also relate to Macromolecular materials industry whether sustainable development.
The relative molecular mass of rubber is 10 ~ 1,000,000, and it can rapidly recover its deformation under big deformation, and
Can be modified, that is, vulcanize.Vulcanize and refer to by certain temperature, pressure and after the time, make the things such as rubber macromolecule and sulfur
There is chemical reaction in matter, and be cross-linked to form the macromolecular elastomer with three-dimensional network-like structure.Therefore, with network-like
The vulcanized rubber regeneration of structure becomes the macromolecular material with line plastic construction, it is necessary to optionally destroy in rubber molecule
Established cross-bond, i.e. " desulfurization ".Existing method for desulfuration regeneration of waste rubber has chemical regeneration method, physics method of reproduction and life
Thing method of reproduction, wherein physics method of reproduction is in the majority, and it is to utilize external energy, and the three-dimensional network for making crosslinking rubber is crushed, waste and old
Rubber becomes linear structure by network structure, forms the reclaimed rubber with mobility.
The regeneration of waste old physics adopts Plasticator shearing-crushing, in order to reach preferable shearing-crushing effect, fully
Desulfurization, increases shearing dynamics to realize often through lengthening spiro rod length and increasing screw speed, increases spiro rod length, on the one hand
Equipment cost increases, and another aspect equipment takes up space greatly.And excessively increasing screw speed then causes screw rod wear rate higher, the life-span
It is not long.Existing Plasticator is unstable due to shearing force, causes desulfurization unstable, and product quality is affected.When processing ternary
During the third waste old of second, only shearing force is increased by accelerating screw speed, desulfurized effect is not good.For this purpose, exploitation one kind can
Processing the stable Plasticator screw rod of various waste olds, desulfurization becomes problem demanding prompt solution.
The content of the invention
The invention provides a kind of Plasticator screw rod for various rubber industry wastewaters, if being arranged by the discharge end in screw rod
Dry helical gear, under relatively low screw speed, there is provided larger shearing force, desulfurization in the course of processing is stablized, it is only necessary to changed
The gear of different tooth bar numbers, it is possible to process different types of waste old, substantially increases the use range of Plasticator, carries
The high desulfurization quality of waste old.
The technical proposal for solving the technical problem of the invention is：
A kind of Plasticator screw rod for various rubber industry wastewaters, including spiro rod section, feed end and discharge end, the discharging of the screw rod
End is provided with installation portion, tight lock part, locking member and several gears, and the gear inwall is provided with keyway, and installation portion is provided with and key
The flat key that groove matches, the gear is slidably connected on installation portion by keyway and flat key mating reaction, the locking member with
Tight lock part is detachably connected.Gear is set up in the feed end of screw rod, by more gear changing, the shearing dynamics of screw rod is adjusted, so as to
Realize the purpose of the various waste olds of processing.
Preferably, the tight lock part is provided with external screw thread, locking member is provided with female thread, and locking member passes through with tight lock part
The matching thread connection of internal and external threads, the internal and external threads are left-hand thread.
Preferably, the number of the gear is 2-6.
Preferably, the gear is helical gear.
Preferably, the tooth bar number of the gear is 20-30, tooth bar number is more, and space width is less, and shearing force is got over
Greatly, it is adapted to the big waste old of processing state of cure (vulcanization) height, the degree of cross linking.
Preferably, the teeth directional centrage of the gear is 15-50 degree with the angle of inclination of axis, angle of inclination is bigger,
Shearing force is bigger, but process velocity is slow.
It is further preferred that the transverse tooth thickness is 3-5mm, it is 12-15mm that the facewidth is 8-10mm radiuss of addendum, and root radius is
10-13mm。
Beneficial effects of the present invention are：
1st, several gears are arranged by the feed end in screw rod, increases the shearing dynamics of screw rod so that Waste rubber desulfurization is steady
Fixed, product quality is higher.
2nd, the shearing dynamics of screw rod can be changed by changing different tooth bar numbers and space width, it is various so as to realize processing
The purpose of waste old.
3rd, by the setting of gear, it is not necessary to which very long screw rod can reach larger shearing dynamics, reduce equipment into
This, reduces equipment and takes up an area space.
