Abstract
The utility model provides a rubber desulfurization extruder. The extruding screw of the utility model is a screw rod with double screw threads, and the main, auxiliary screw threads in segmenting mode. The connection of the screw rod and a supporting base is adopted. The machine head of round stage-shaped core is adopted. The machine is used for carrying out desulfurizing regeneration for waste rubber. The quality achieves the standard which is higher than B grade of the national standard of regenerating rubber.
Description
The utility model relates to a kind of devulcanization of rubber extruder, but by the extruding screw, the bolted head of the sleeve port of export that rotate by driven by motor in the temperature adjustment sleeve that is supported on pedestal, the configuration sleeve, and the feed hopper, the speed changer composition that are arranged on the sleeve arrival end, belong to the press technology.
In the regeneration techniques of scrap rubber, a kind of extruding doctor treatment that does not produce contaminated environment is arranged, as the disclosed technology of U.S. Pat P2653348.This technology adopts that a kind of single thread deepens, Variable pitch screw.Reclaimed rubber after the processing, its product performance index has reached the physical and chemical indexes of floating reclaim, and the product quality fluctuation is little.But one start screw deepens, Variable pitch screw, exists inadequately to the shearing plasticizing capacity of sizing material, influences the deficiency of reclaimed rubber quality.In order to guarantee shear effect, force and adopt the shallow slot screw thread, but bring the adverse consequences that reduces production capacity.
At the above-mentioned deficiency of existing desulfurization extruder technology, the utility model provides a kind of desulfurized effect to be better than the single-head screw extruder, constant product quality, the devulcanization of rubber extruder that output is high again.
Compare with the desulfurization extruder of single-head screw, the utility model carries out following improvement technically: the screw rod that adopts double thread and major and minor threaded segments to be provided with.Be specially six sections variations: feeding section, screw rod be double end equidistant, etc. deep thread; First extruded segment is the gradually shallow screw thread of uniform pitch, screw channel; The first plasticising section, dark, equidistant for the sudden change of major and minor screw-type, etc. dark; Second extruded segment, the second plasticising section, the 3rd extruded segment, all be equidistant, etc. dark, but each intersegmental spiral groove depth does not wait.The utility model also twines cooling water pipe in sleeve wall is provided with spiral groove, groove, and twining configuration heating wire sheet between water pipe, these technical measures, the preheating of sizing material and desulfurizing agent when start, and heat radiation is very favorable in the extrusion process.
The utility model is also abandoned the usually water-cooled cross-head of casting cavity, adopts isometrical barrel, be connected with bearing with screw rod, thus the head of the adjustable garden platform shape core in position.
Use devulcanization of rubber extruder provided by the utility model, waste old is carried out desulfurization regeneration, its quality reaches more than the reclaimed rubber national standard secondary.
Accompanying drawing is the overall schematic of devulcanization of rubber extruder provided by the utility model, Fig. 2 is existing desulfurization extruder extruder head organigram, Fig. 3 is this devulcanization of rubber extruder extruder head organigram, and Fig. 4 is that screw zones screw thread and screw channel change schematic diagram.Below in conjunction with accompanying drawing, further describe the most preferred embodiment technical characterictic.
This devulcanization of rubber extruder by being supported on pedestal (2) but temperature adjustment sleeve (5), the screw rod (12) that configuration sleeve (5) is interior and speed changer (7) output shaft joins, be connected in the head (1) of the sleeve port of export by bolt, be arranged at the feed hopper (6) of sleeve arrival end, and motor (8) is formed.
Here sleeve (5) outer wall has spiral groove (11), and built-in spirality water cooling twines pipe (4), twines and arranges the electric heating piece (3) that is made of electric network between pipe (4).Cooling water and electric heating piece can open and close respectively according to the operating mode needs.
Screw rod (12) in the sleeve (5) is the extruding screw that a double thread and major and minor threaded segments are provided with.Feeding section (13) screw thread be double end equidistant, etc. deep thread; The screw thread of first extruded segment (14) is equidistant, and the gradually shallow screw thread of groove depth; The first plasticising section (15) then is major and minor screw-type, its major and minor screw thread is equidistant separately, etc. dark; Second extruded segment (16), the second plasticising section (17), the 3rd extruded segment (18) all are equidistant, wait deep thread, and still, each intersegmental spiral groove depth does not wait.Second extruded segment (16), the second plasticising section (17) the 3rd extruded segment (18) spiral groove depth and abutting end section groove depth are dark, shallow, dark type sudden change.
The outlet of head (1) has isometrical barrel (9), and is connected in bearing with screw rod, and its turnover position can change by rotary screw, thus the taper core pattern (10) in levelling discharging opening cross section.
This most preferred embodiment has been described the devulcanization of rubber extruder of a screw diameter φ 150mm.Its primary tread lead is at 120-150mm, spiral groove depth 10-30mm, spiral shell rib width 9-12mm, the compression ratio 2.0-2.5 of screw rod.The first extruded segment bottom diameter is gradient to 130mm by 90mm.Deputy thread is arranged in the first plasticising section total length.Helical pitch can draw according to the relevant parameter calculation formula of major and minor screw thread.The difference in height of deputy thread and main thread spiral shell rib is 0.5-2.5mm.The gap of screw rod and sleeve then selects 0.350-0.560mm more suitable.Electric heater can adopt 8-10KW, and cooling water pipe is if pass to running water, and bore 20mm gets final product.
