Carry out serious air pollution, and make material in the condition of high temperature and air contact cause the decline of properties of product, if not
Cool down in time, or even desulfurization powder spontaneous combustion can be caused.And high-temperature pressure, such as double helix, single-screw continuous desulfurization technology, its dependence
Wall temperature conducts heat, and with the rubber powder of barrel directly contact with good adherence of on spiral or barrel, is more easy to fouling according to Electromagnetic Heating；And no
By mono-/bis-spiral all nothing automatical cleaning ability, fouling can be increasingly thicker, ultimately results in putty, there is presently no effective equipment and
Method solves this problem；Additionally, these technology have lacked the protection of water, mono-/bis-than conventional high-temperature high pressure dynamic desulfurization technology
Air in spiral under the high temperature conditions can considerable damage rubber C-C chain, cause properties of product decline.Therefore, a kind of preferable
The device of continuous coo1ing desulfurization powder, not only will prevent material adhesion at high temperature with good self-cleaning function, and
Will be with the closed function of excluding air, to ensure the performance of product.Herein according to the full engagement spiral shell of parallel double-screw extruder
Texel part has good self-cleaning function and good vacuum exhaust effect, and the conveying of parallel double helix blending transportation machine
The advantages of amount is big, contact heat transfer effect is good, structure is relatively easy, invention devise one kind and prevent adhesion double rank birotor continuous coo1ing
The device of desulfurization powder, realizes, in the continuous high-efficient heat transfer cooling to high temperature desulfurizing rubber powder and course of conveying, preventing with this
Rubber powder and the adhesion of cooling device.The present invention will provide one to efficient, continuous, the stable temperature reduction technology of high temperature desulfurizing rubber powder
Plant new device and method.
