Description

Technical Field

[0001] The invention relates to the technical field of vacuum drying devices, in particular to a vacuum drying device used for preparing polymer materials. Background Art

[0002] Polymer materials, also known as polymer materials, polymer molecular chains are connected by covalent bonds to atoms, and are connected in a simple structural unit and repetitive manner. The molecular chains are connected by secondary bonds, and copolymers are formed by the polymerization of two or more monomers.

[0003] During the preparation process of polymer materials, they need to be dried. The existing drying and drying devices use a warm air blower to dry the polymer materials. During the drying process, the polymer materials are in contact with each other, and the wet gas generated by the drying of the polymer materials cannot be discharged, thereby affecting the drying effect of the polymer materials.

[0004] To this end, those skilled in the art have conducted research and improvements, such as a vacuum drying device for polymer material preparation with application number CN202220044043.X. This technical solution introduces dry gas from the air inlet pipe, discharges the gas in the heating mechanism from the air outlet pipe, and the gas between the polymers enters the groove from the first through hole through the second through hole. The gas in the groove is discharged from the air outlet pipe, which can effectively discharge the wet gas between the polymer materials. However, in this technical solution, the materials are piled up and placed, and the fixed plate cannot effectively disperse the materials, affecting the drying effect. To this end, we propose a vacuum drying device for polymer material preparation. Summary of the invention
