Vacuum pulse drying machine

Abstract

The invention relates to the technical field of drying equipment, in particular to a vacuum pulse drying machine. The vacuum pulse drying machine comprises a drying box and a vacuumizing device, and is characterized in that a drainage pipe is arranged at the bottom of the drying box, a plurality of longitudinally-arranged plane heating plates are arranged inside the drying box, a vacuum measurement device is arranged inside the drying box, the vacuum measurement device is electrically connected with a PLC, and the vacuumizing device is also electrically connected with the PLC. Traditional heating pipes are replaced with the plane heating plates, and materials are heated more uniformly and dried more thoroughly; in addition, the vacuum measurement device is arranged inside the drying box, vacuum fluctuation adjustment can be achieved through the PLC, and water of the materials can overflow more rapidly and efficiently; a front filling door and a back filling door are designed, front filling and back filling can be achieved, the filling operation is promoted, space use of the vacuum pulse drying machine is more sufficient, and the effective volume and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a vacuum pulse dryer. Background technique [0002] The vacuum pulse dryer is to heat and dry the material to be dried under vacuum conditions. It uses a vacuum pump to pump air and dehumidify, so that a vacuum state is formed in the working room, thereby speeding up the drying rate of the material. However, the existing vacuum pulse dryer is heated with a heating tube structure, which causes the material to be heated unevenly, and it is easy to cause the material to be partially heated. Agglomeration or paste deterioration due to temperature difference; the existing vacuum pulse dryer can only maintain a constant vacuum value after vacuuming, and the solvent is not easy to discharge, especially for materials that are easy to foam; the existing vacuum pulse dryer can only Opening the door restricts the feeding of materials, which is inconvenient for feeding.
