1, the paraformaldehyde vacuum dryer - equipment overview

The paraformaldehyde vacuum drying machine is a horizontal intermittent operation heat conduction drying equipment, which can be used for drying and processing of easily oxidized, easily broken, heat-sensitive powdery, syrupy and paste-like materials.

The paraformaldehyde type vacuum dryer comprises a casing, the casing has a feeding port, a discharging port and a vacuuming port, the casing is also provided with a heating spacer, the casing is provided with a stirring device, and the driving stirring device is also provided. The rotating driving device comprises a hollow hollow boring shaft and a plurality of masts arranged on the hollow boring shaft, wherein the hollow hollow boring shaft is provided with a central tube, the rafter is provided with a rafter blade, and the hollow boring shaft is provided The two ends are mounted on the casing through a bearing seat. One end of the hollow boring shaft is a closed port and the other end is open. One end of the closed end of the hollow boring shaft is connected to the driving device, and the central pipe protrudes from one end of the opening of the hollow boring shaft. The heat conductive medium can be introduced into the central pipe and flow out from the gap between the hollow boring shaft and the central pipe, so that the temperature of the stirring device is increased to heat the material, and the heat conductive medium can be steam, hot water or hot oil. After the hollow crucible is passed into the heat-conducting medium, the stirring device is heated, thereby achieving the purpose of heating the material from the inside of the casing, and heating the material together with the heating partition, so that the material is heated more uniformly, the production efficiency is improved, and the drying time is shortened.
