Problems solved by technology

However, the main engine is intermittent in the production process, and the hopper must be pulled out to discharge each batch of dry materials, which is not only labor-intensive, time-wasting, and inefficient; but also the equipment will contain parts of the system during the unloading process. Leakage of solvent inert gas into the operating space is dangerous

Abstract

The invention relates to a main machine of a closed cycle boiling dryer, which is applicable to material drying and solvent reclaim in the fields of chemicals, medicines and the like, and comprises a hopper (4) and a porous plate or sintered screen (5), wherein the porous plate or sintered screen (5) is transversely arranged at the bottom of the hopper (4). The main machine is characterized in that the porous plate or sintered screen (5) has a turnover structure. The main machine can be used for continuous production, prevent materials from contact with the outside and lower the possibility of pollution to the materials.

Description

(1) Technical field [0001] The invention relates to a closed-circuit circulation boiling dryer, which is suitable for material drying and solvent recovery in the fields of chemical industry and medicine. (2) Background technology [0002] Before the present invention was made, the structure of the conventional closed-loop boiling dryer was as ZL200820041009.7. The dryer can effectively recover the solvent in the material, and for the material containing flammable and explosive solvents, the system can be filled with inert gas so that it loses the combustion aid and does not explode. However, the main engine is intermittent in the production process, and the hopper must be pulled out to discharge each batch of dry materials, which is not only labor-intensive, time-wasting, and inefficient; but also the equipment will contain parts of the system during the unloading process. Leakage of solvent inert gas into the operating space is dangerous. (3) Contents of the invention ...
