Description
One, technical field
The present invention relates to a kind of synthetic rubber screw expansion dryer, particularly combined type double screw swell drier.
Two, background technology
At present, French, Anderson company on market is generally single box-like expansion-exsiccation machine structure of screw rod group, and discharging controls outlet sizing material material water content by adjusting the size of cone aperture.WeldingEngineers company is generally twin screw (screw rod monoblock type) expansion-exsiccation machine structure, and discharging controls the water content in extruding-desiccation machine outlet material by adjusting the size of discharging opening aperture.The double screw swell drier of China all relies on the import of above-mentioned company, but above company expansion-exsiccation machine exists following problem:
Equipment investment is big, and operation cost is high, and energy consumption index is high；Drive system precision is not high, and floor space is big；The sizing material that monoblock type screw rod is suitable for has certain limitation, and technology for repairing wear is complicated；Single screw expansion dryer outlet sizing material water content is higher, and the energy consumption of subsequent handling is higher；Discharging section temperature is high, it is easy to cause sizing material degeneration.
Three, summary of the invention
Patent of the present invention to solve the technical problem that and to be to provide combined type double screw swell drier, in the operation of synthetic rubber expansion drying, the present invention (prevents degraded) under minimum shearing force, completed conveying, extruding by two counter rotating screw rods, sheared and expansion process process, make moisture be uniformly dispersed, temperature homogeneous, make sizing material be reduced to 2%～3% at the water content of outlet, enter back into next step and dry so that it is the requirement that volatile ingredient is up to state standards.
In order to solve above-mentioned technical problem, the present invention adopts combined type double screw swell drier, including motor, shaft coupling, reduction box, reduction box lubrication, extrusion system, pelletizing system, base, pipeline composition, main being technically characterized in that wherein adopts monoblock type reduction box to instead of traditional split-type structural；Combined type double screw version in extrusion system instead of original monoblock type screw form；The box-like replacement of short machine barrel soldering group original lead aircraft cylinder in extrusion system welds knockdown form, and 2 original joint machine barrels are become 4 joint machine barrels；And add temperature control system, more can ensure the temperature of outlet sizing material reliably.
Compared with French, Anderson, WeldingEngineers company expansion-exsiccation machine, its advantage of combined type double screw swell drier of the parts through replacing: transmission accuracy improves, and more ensure that the reliability of equipment；Reduced footprint；Reduce investment cost；Technology for repairing wear simplifies；Achieve the strict temperature requirement controlling sizing material, improve the quality of goods；Production capacity improves；Automatic control level improves, and equipment protection interlocking is more perfect.

Five, detailed description of the invention
Below in conjunction with accompanying drawing, this patent is specifically described:
As it is shown in figure 1, double screw swell drier mainly by: motor 1, shaft coupling 2, reduction box 3, reduction box lubrication 4, extrusion system 5, pelletizing system 6, temperature control system 7, base 8, pipeline 9 etc. form.The parts being wherein replaced have:
1. reduction box changes architomia formula structure into monolithic construction, as shown in Figures 2 and 3.Monoblock type reduction box 15 incorporates reduction box 11, shaft coupling 12 and speed ratio case 13 and defines a closing entirety, transmission accuracy height can be reached, compact conformation, floor space is little, strength of gear is little, bearing capacity is high, and the safety coefficient of touch strength of gear and bending strength is big, also ensures two screw rod stress equalizations.
2. the form of two assembled screw rods in extrusion system, instead of monolithic construction, as shown in Figure 4 and Figure 5.Monolithic construction is adopt to threaded for overall screw rod 16 and extension 17, and screw rod tail adopts internal spline 18 to be connected with reduction box 15.Fabricated structure is to adopt involute spline to be connected with mandrel 20 screw element 19, and mandrel afterbody adopts external splines 21 to be connected with reduction box 15.Involute spline connects the precision coordinated higher than threaded precision, improves the requirements such as the linearity of screw rod, axiality；Fabricated structure form can according to the combining form of different technique adjustment screw elements 19, and screw element is also convenient for changing if any abrasion, and efficiency is high, need not destroy by whole screw rod, saves cost；Fabricated structure form, changes internal spline 18 into external splines 21, significantly lowers the difficulty of processing.Having installation compared with monolithic construction simple, convenient, maintenance maintenance is more laborsaving, removes and installs quick.
3. the box-like replacement of the short machine barrel soldering group original lead aircraft cylinder in extrusion system welds knockdown form, as shown in Figure 6 and Figure 7.2 original joint machine barrels are become 4 joint machine barrels, reduces the difficulty of machining and Technology for Heating Processing；It is welded with the chuck 24 of steam heating and temperature control outside the cylinder 22 of machine barrel, inside cylinder, studs with lining 23.The version of lining 23 adopts " ∞ " font, and feeding section and compression section lining have uniform groove, increases sizing material conveying in machine barrel.The inner surface of lining 23 all adopts spun casting alloy, reaches not only corrosion resistant but also wear-resisting performance；Compared with original lead aircraft barrel structure, the newly-increased groove that is provided with of the end face of short machine barrel, built-in ring 26, more ensure the sealing between machine barrel；The pin-and-hole 27 that is located through between machine barrel ensures.
4. combined type double screw swell drier expansion arc adds temperature control system 7, and temperature control system mainly have employed source pump to control temperature, to guarantee to imitate the temperature reasonably controlling outlet micelle, more ensure that elastomeric monopolizing characteristic.
