Problems solved by technology

For example, when the vacuum belt conveyor is applied to the solid-liquid separation section of α hemihydrate gypsum produced by the liquid phase method, if no heating and heat preservation measures are taken, the filter cake will cool down rapidly during this process, and α hemihydrate gypsum is under low temperature conditions. It is easy to undergo a chemical reaction in a short period of time to become dihydrate gypsum and solidify, resulting in the scrapping of the material

Abstract

The invention discloses a heating insulation device of a vacuum belt conveyor. The heating insulation device is a closed heating insulation cover and is arranged around a vacuum dewatering belt of the vacuum belt conveyor; the heating insulation cover is fixed on the frame of the vacuum belt conveyor; an aeration conduit communicated with the heating insulation cover is arranged above the heating insulation cover. The heating insulation device of the vacuum belt conveyor can keep high temperature; when the heating insulation device is applied to solid-liquid separation of gypsum production, the phenomenon that alpha hemihydrate gypsum is solidified because of changing into hemihydrate gypsum caused by chemical reaction can be eliminated.

Description

technical field [0001] The invention relates to a solid-liquid separation machine for suspension slurry, in particular to a heating and heat preservation device for a vacuum belt conveyor for solid-liquid separation in gypsum production and processing. Background technique [0002] A typical vacuum belt conveyor consists of the following parts: frame, vacuum system, filtration system, water circulation system and power system. Such as figure 1 As shown, the vacuum dehydration belt is composed of porous rubber belt and filter cloth. The upper surface of the vacuum dehydration belt is the material, and a row of vacuum boxes is arranged below it to form a vacuum area. Using the effect of the vacuum area on the material on the vacuum dehydration belt, it can be completed continuously. Filtration, washing, drying and other different processes to achieve solid-liquid separation of materials. The application of vacuum belt conveyor in solid-liquid separation has the advantages o...
