Vacuum cooling warehousing and vacuum delivering system for high-viscosity materials

Abstract

The invention discloses a vacuum cooling warehousing and vacuum delivering system for high-viscosity materials. Hot moisture of the materials is removed by vacuumizing after the materials enter a hot moisture extraction tank with an inverted-cone-shaped lower portion, and the materials are pumped into a first condenser by a material pump, flow downwardly to be cooled by a second condenser and a third condenser, enter a storage tank with an inclined bottom surface to be stored and further cooled and are discharged in vacuum. The vacuum cooling warehousing and vacuum delivering system has the advantages that the high-viscosity materials are subjected to vacuumizing and hot moisture removal before being cooled, so that the situation that product quality is affected by water drops generated by condensation of the hot moisture and the like in the materials during later cooling is avoided; the condensers are arranged ingeniously and the shape of the storage tank is optimized according to properties of the materials, so that the high-viscosity materials are cooled quickly and evenly; a material delivery process is also performed in vacuum, and accordingly, the materials are prevented from being mixed with the air. The vacuum cooling warehousing and vacuum delivering system can be used for cooling and delivering of chemical high-viscosity materials.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a system for evacuating and cooling high-viscosity materials into and out of a bin. Background technique [0002] In the field of chemical adhesive production, such as polyurethane, silicone rubber, etc., it is often necessary to synthesize some viscous base materials first, and then use these base materials as raw materials to further synthesize finished products. After the base material is synthesized, the temperature is generally high, and it needs to be cooled before the finished product is synthesized. Because most of these base materials are high-viscosity materials, the viscosity of the materials is high, and the fluidity decreases significantly as the temperature decreases. Therefore, the current conventional practice is to simply cool the synthesized materials and wait for them to cool naturally after entering the storage tank. This conventional cooling method, on the o...

Problems solved by technology

This conventional cooling method, on the one hand, is time-consuming. On the other hand, due to the high-viscosity material, the heat dissipation is slow. After entering the storage tank, even if it is naturally cooled for a long time, there is still a phenomenon of local temperature unevenness. When subpackaging, the volumetric measurement method is generally used for batching, and local temperature unevenness will lead to inaccurate measurement, affecting subpackaging and product synthesis; moreover, after simple cooling, it is inevitable that there will still be unvolatilized hot steam in the material etc. In this way, after cooling down and condensing in the later stage, water droplets will remain in the cooled product, affecting product quality
