Pulsating replacement type novel vacuum dryer device

Abstract

The invention discloses a pulsating replacement type novel vacuum dryer device and belongs to the technical field of material drying. According to the pulsating replacement type novel vacuum dryer device, a rotary tank body is subjected to hanging supporting through a rack, the end, connected with the rack, of the rotary tank body is provided with a rotary air guide device, the rotary air guide device is connected with the rotary tank body and an air supply mechanism, and the end, close to the rotary air guide device, of the rotary tank body is further provided with an air exhausting mechanismused for air exhausting vacuumizing. The pulsating replacement type novel vacuum dryer device is scientific and reasonable and safe and convenient to use, the inner portion of the rotary tank body isheated by utilizing a first clamping sleeve cavity and a heat source, indirect heating is realized, material pollution is avoided, in the material drying process, one path of inert gases heated by aheater is additionally arranged to perform convection current contact with materials inside the tank body through a pulse gas filter plate, heat exchanging is realized, meanwhile, the gases after theheat exchanging are discharged out through the air exhausting mechanism, the heated inert gases are taken as carriers of water vapor discharging after the material drying, and the material drying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of material drying, in particular to a new type of pulsating 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 mate...

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;
