A pulsating displacement vacuum dryer device

Abstract

The invention discloses a pulsating displacement vacuum dryer device, which belongs to the technical field of material drying. The rotary tank body is supported in the air by a frame, and a rotary air guiding device is arranged at one end of the rotary tank body connected to the frame , the rotary air guide device is connected to the rotary tank body and the air supply mechanism, and the end of the rotary tank body close to the rotary air guide device is also provided with an exhaust mechanism for exhausting and vacuuming. The invention is scientific and reasonable, safe and convenient to use , using the cavity of the first jacket and the heat source to heat the inside of the rotary tank to realize indirect heating and avoid polluting the material. The materials in the tank are in convective contact to realize heat exchange. At the same time, the gas after heat exchange is discharged through the exhaust mechanism, and the heated inert gas is used as the carrier for the water vapor discharge after the material is dried, so as to improve the drying efficiency of the material.

Description

technical field [0001] The invention relates to the technical field of material drying, in particular to a pulse displacement vacuum dryer device. Background technique [0002] In the pharmaceutical, liquid crystal, chemical, food and other industries, the processing and production of raw materials is inseparable from the drying of raw materials, and there are various types of drying equipment for raw material drying, and for the existing technology, raw material drying equipment There are the following problems when using: [0003] 1. When the existing drying equipment is in use: in order to make the drying more efficient, the inside of the drying tank will be vacuumed, but after vacuuming, because there is no carrier, the water vapor after drying cannot be directly discharged, which affects the drying process. In addition, it takes a certain amount of time to evacuate the inside of the drying tank through a vacuum pump, which affects the efficiency of material drying; ...

AI Technical Summary

Problems solved by technology

[0003] 1. When the existing drying equipment is in use: in order to make the drying more efficient, the inside of the drying tank will be vacuumed, but after vacuuming, because there is no carrier, the water vapor after drying cannot be directly discharged, which affects the drying process. In addition, it takes a certain amount of time to evacuate the inside of the drying tank through a vacuum pump, which affects the efficiency of material drying;

[0004] 2. When the existing drying equipment is in use: the gas supply method is incorrect, and the whole-process supply method is adopted, so that the water vapor inside the accumulated material cannot be discharged well;

[0005] 3. When the existing drying equipment is in use, it cannot ensure that the gas used for drying passes through the material evenly, and the moisture in the material is discharged, so that the drying and heating of the material are uneven;
