Device for physically purifying low volatile matter in macromolecular compound

Abstract

The invention discloses a device for physically purifying a low volatile matter in a macromolecular compound. A heating tank of the device adopts heating oil to heat or adopts an electric heating way; the heat conduction oil heating of the heating tank is implemented as follows: heat conduction oil is filled into the heating tank, then the heat conduction oil is heated, so that the temperature of the oil is increased to a needed temperature, and then the hot oil is transported to a place needing to be heated through a circulating oil pump; the electric heating way is implemented as follows: an electric heating plate or an electric heating coil are electrified to heat the place needing to be heated. According to the physical characteristics of the low volatile matter in the macromolecular compound and inorganic mineral powder, an air exhausting pump and multiple filter layers are provided, the low volatile matter completely volatizes through adopting a physical method by utilizing a vacuum negative-pressure environment under the condition that the heating time is limited and the boiling point of the volatile matter is not reached, the consumed time is short, the energy consumption is saved, and the volatile matter can be thoroughly volatized.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a physical purification device for low volatile matter in high molecular compounds. Background technique [0002] The problem of some low-molecular-weight volatiles contained in high-molecular compounds and the residual moisture contained in inorganic mineral powder cannot be completely solved in ordinary mixing and stirring, and the residue will greatly affect the quality and modified performance of modified products . The common method is to use the method of stirring while heating to volatilize the moisture of low molecular volatiles and inorganic mineral powder, but this method is inefficient, and the volatilization is not complete, and there are many residual materials, which affects the quality of the product. [0003] The traditional purification process uses heating to promote the volatilization of low volatiles. This process requires equipment to be equipped with jacket...
