Heat pump drying device for water on surface of material

Abstract

The invention relates to a material surface water heat pump drying device, which is characterized in that it mainly includes a thermal insulation storage body, a screw conveying device, a drying medium processing box, an air guiding component and a heat pump system, and the thermal insulation storage body has a built-in drying medium processing box and a conveying network The screw conveying device with a belt, the screw conveying device adopts a double-screw conveying structure; the dry medium treatment box includes the upper part of the dry medium heat pump processing module and the lower part of the dry medium turbulence module, and the dry medium heat pump processing module includes a bag filter, air duct and The drainage fan and the dry medium heat pump processing module also have a built-in evaporator of the heat pump system and a condenser in the storage, and a built-in air guide component for guiding the air flow in the thermal insulation storage. The combination of the screw conveying device built in the closed insulation box and the heat pump system is used to dry and dehumidify the material. The dehumidification effect is good, the operating cost is low, and the device occupies a small space. The double condenser system can prevent the temperature in the warehouse from being too high. The compressor suction temperature is too high.

Description

technical field [0001] The invention relates to a material drying system, in particular to a material surface water heat pump drying device. Background technique [0002] Material drying is different from other drying of wood, vegetables, medicinal materials, fish, etc. It does not need to remove the moisture inside the material, but only needs to remove the moisture on the outer surface of the formed material. For a long time, natural ventilation is often used to remove the surface water of materials. This process has a long production cycle and unstable process. It cannot realize continuous production and cannot meet the market demand in peak seasons. In recent years, the open hot air drying process has also developed rapidly. This process is superior to natural air drying and can realize continuous mass production. However, the open hot air drying process requires steam heating equipment or electric heating equipment The drying medium is heated, and then the drying mediu...

Problems solved by technology

Due to the limitations of the heat resistance of materials or material packaging and the operating conditions of heat pumps, in order to effectively dry materials, conventional heat pump drying devices are often made very large, with low space utilization efficiency and comprehensive application efficiency, and a long drying cycle, which is not conducive to comprehensive promotion.
