Abstract
The utility model provides a screw extrusion expansion drying machine, which is composed of a mould plate, a screw, a barrel body, a lining, a vapor jacket, a feed port, a shaft coupling, a cutter device and a machine frame. The utility model is characterized in that a thread sleeve of the conveying section of the screw is formed by the combination of thread sleeves of equal groove depth and equal thread pitch, and two thread sleeves which are arranged at the section end and have decrescent thread pitch, wherein, an end thread edge of each thread sleeve is continuously and smoothly connected with a starting thread edge of the next thread sleeve. The compression section of the screw is composed of a plurality of thread sleeves with equal groove depth and gradually decrescent thread pitch, and a plurality of thread sleeves with equal thread pitch and gradually decrescent groove depth, and the metering section of the screw is composed of a plurality of thread sleeves with equal thread pitch and equal groove depth. The screw extrusion expansion drying machine has the advantages of large conveying capacity, high melting performance, good drying effect of the machine.
Description
Technical field
The utility model relates to a kind of screw rod extrusion expansion drying machine.
Background technology
Screw rod extrusion expansion drying machine is a kind of drying equipment during China Synthetic Rubber Industry is produced, and plays a crucial role in drying process.Existing screw rod extrusion expansion drying machine generally partly is made up of template, screw rod, cylindrical shell, lining, vapour jacket, charging aperture, shaft coupling, cutter, frame etc., adopt building block system swivel nut combining structure, the spiral groove depth that is combined as of swivel nut equates, change the screw channel volume by changing pitch, or pitch is equal, changes the screw channel volume by changing spiral groove depth.The screw rod of these style combinations, its mass transport and melting behaviour are low, unstable product quality, work elasticity is narrow, and the industry characteristics of screw rod are relatively poor, and the drying effect of equipment is poor, and disposal ability is little.
Summary of the invention
The utility model provides a kind of conveying and melting behaviour height of screw rod, and the equipment drying effect is good, the screw rod extrusion expansion drying machine that the device processes ability is big.
In order to achieve the above object, the transportation section swivel nut of screw rod of the present utility model is by the equivalent gullet depth uniform pitch, and being provided with the combination of the swivel nut that two pitch diminish at the section end, the end spiral shell rib of each swivel nut becomes continuously smooth to be connected with the initial spiral shell rib of a back swivel nut, to eliminate returning charge, not material feeding; The pitch gradual change of the compression section of screw rod by several equivalent gullet depths swivel nut and several uniform pitch and the swivel nut of groove depth gradual change is formed, this structure both can well guarantee that screw rod adapted to the required compression melt capacity of different material, also reduce the material movement resistance simultaneously, reduce temperature of charge, eliminate material and cross thermal degradation; The metering section of screw rod by several not only uniform pitch but also etc. the dark swivel nut of screw channel constitute, steady with the guarantee system pressure and temp.
As a kind of improvement of the present utility model, inner surface at lining has trapezoidal groove vertically, and gradually shallow vertically be 0 to second section degree of depth, improved the friction factor of cylindrical shell and material like this, increase the angle of traction of material movement, thereby improve the production capacity of solid conveying section.Friction factor increases and can improve frictional heat simultaneously, and the material melting time is shifted to an earlier date, and strengthens the screw rod melt capacity, and facilitation is also played in the foundation of melt zone system temperature and pressure homenergic.And screw diameter can increase drying capacity more than or equal to 250mm.
As a kind of improvement of the present utility model, the shear rod on the cylindrical shell connects the socket joint mode by flange and is installed on the cylindrical shell.
As another kind of improvement the of the present utility model, the main frame of screw rod extrusion expansion drying machine adopts cog-wheel coupling to connect with drive part.
