Abstract

The invention discloses a bipyramid rotation vacuum drier. The bipyramid rotation vacuum drier comprises a pot body, a stirring motor, a thermal resistor, a vacuum cover and a pipe opening, wherein the pot body is composed of the interlayer outer wall and the interlayer inner wall, the inner wall of the pot body is the enamel inner wall, and a feed port of the pot body and a discharge port of the pot body are provided with a feed valve and a discharge valve respectively. Preferably, a steam electromagnetic valve can be arranged in a steam inlet. By means of the technical scheme, the pressure inside a pot can range from -0.09Mpa to 0.096Mpa. The bipyramid rotation vacuum drier has the functions of reacting, concentrating, crystallizing, washing, filtering, centrifugating, drying and the like, the technological processes can be finished on one device, and pollution produced in the process of transshipment of materials is reduced. Meanwhile, labor and materials in the process of operation are saved, and the safety of the production process is improved. The inner wall structure is of an enamel structure, so that the bipyramid rotation vacuum drier is washed more easily. Due to the fact that the feed valve and the discharge valve are arranged, the sealing performance inside the pot can meet the demand of the designed pressure.

Description

technical field [0001] The invention relates to a multifunctional double-cone rotary vacuum dryer, which is suitable for concentration, mixing and drying of powdery, granular and fibrous materials in chemical, pharmaceutical, food and other industries. Background technique [0002] In the chemical, pharmaceutical, food and other industries, after the material reaction, concentration or crystallization, washing, filtration or centrifugation is completed, it is then dried with an ordinary vacuum dryer. There are the following problems when using an ordinary vacuum dryer for drying: 1. The ordinary vacuum dryer has a single function and can only be dried; 2. The double-cone rotary vacuum dryer in the prior art is not easy to clean and cannot discharge all the materials. Defects; 3. The tank body has poor sealing performance and cannot meet the requirements of the design pressure in the tank. SUMMARY OF THE INVENTION [0003] Aiming at the problems existing in the above-menti...
