Intermittent solid phase thickening device

Abstract

The invention discloses an intermittent solid-phase tackifying device. The intermittent solid-phase tackifying device comprises a rotary drum reaction barrel body composed of an inner barrel body and an interlayer layer arranged outside the inner barrel body, wherein the two ends of the rotary drum reaction barrel body are movably supported on a supporting frame and can be driven by a driving mechanism to rotate; one end of the rotary drum reaction barrel body is connected with a heat-conduction oil circulating system; the heat-conduction oil circulating system is communicated with the interlayer layer of the rotary drum reaction barrel body by a rotary drum oil pipe; the other end of the rotary drum reaction barrel body is connected with a vacuumizing system; a vacuumizing device in the vacuumizing system is communicated with the inner barrel body of the rotary drum reaction barrel body; the rotary drum oil pipe is provided with a filter; the parts of the rotary drum oil pipe, which are at the two ends of the filter are provided with check valves respectively; a dust separator is arranged on a vacuumizing pipeline between the vacuumizing device and a vacuum pipe. The intermittent solid-phase tackifying device has the beneficial effects that impurities in heat-conduction oil can be effectively prevented from forming sediments in the interlayer layer and can effectively prevent grain-shaped dust from entering the vacuum pump and influencing the normal work of the vacuum pump.

Description

technical field [0001] The invention relates to a thickening device for polyester materials, in particular to an intermittent solid phase thickening device. Background technique [0002] High-viscosity polyester is required for the production of polyester industrial yarn, non-woven fabric, film film, engineering plastics, etc. The intermittent solid-phase thickening device is a kind of thickening device, and its structure includes: drum reaction cylinder, the drum reaction cylinder includes the inner cylinder and the jacket layer arranged outside the inner cylinder, the drum reaction cylinder It is movable supported on the support frame and can rotate under the drive of the driving mechanism. One end of the drum reaction cylinder is connected with a heat transfer oil circulation system, and the heat transfer oil circulation system is connected to the jacket layer of the drum reaction cylinder through the drum oil pipe. Through, the other end of the drum reaction cylinder is...

AI Technical Summary

Problems solved by technology

The above-mentioned intermittent solid-phase thickening device has the following disadvantages: on the one hand, the heat transfer oil in the heat transfer oil circulation system inevitably contains impurities, and after entering the jacket layer of the drum reaction cylinder, it is easy to form precipitates therein, thus affecting The heating or cooling effect of the drum reaction cylinder; on the other hand, the air with water vapor extracted by the vacuum pump contains fine granular dust, and the fine granular dust will enter the vacuum pump along with the vacuum pipeline, thus affecting the vacuum pump. normal work
