Evaporation concentrator

Abstract

The invention relates to an evaporation concentrator used for concentrating viscous and easy-scaling and easy-crystallizing materials in the pharmaceutical and chemical industry production. The evaporation concentrator comprises a heater, an evaporation cavity, material shoveling plates and a transmission shaft. The heater is mounted in the evaporation cavity, and provided with a plurality of material shoveling plates circumferentially and symmetrically. The transmission shaft is arranged at one end of an evaporation cavity body and penetrates through the evaporation cavity body to be connected with the heater. Supporting rolling systems are arranged on two sides at the bottom of the evaporation cavity, and the heater can rotate on the supporting rolling systems under the drive of the transmission shaft. According to the evaporation concentrator, the structure is compact as the heater built-in way is utilized; the evaporation cavity and the heater are free of direct abrasion, so that devices are not damaged, and material quality is stable; the heater rotates in a rolling mode, and materials are heated in a circulation mode, so that the heating is even, energy consumption is reduced, and the obtained material concentration is stable; and work holes are arranged in the evaporation cavity, accordingly, concentration of materials can be timely detected, and materials are convenient to detect so as to control the concentration.

Description

Technical field [0001] The invention relates to an evaporation concentrator, which is used for the concentration of viscous and easy-to-scaling crystalline materials in pharmaceutical and chemical production. Background technique [0002] At present, the common equipment for preparing viscous and easy-to-scale crystalline materials in pharmaceutical and chemical production includes forced external circulation evaporator and rotary scraper evaporator. The first type of forced external circulation evaporator consumes a lot of power, has poor concentration effect, and the equipment is easy to wear and the worn-out metal material contaminants affect the quality of the material; the second type of rotary scraper evaporator covers a large area and consumes a lot of energy. There are also material contaminants that are easy to wear and wear down, and the end point concentration is uncontrollable, which affects productivity. Summary of the invention [0003] Based on the above-mentioned ...
