Powder material drying and cooling integrated device

Abstract

The invention relates to a powder material drying and cooling integrated device which is designed to solve the problems that drying and cooling of powder materials are finished in different devices, and accordingly energy consumption is high and the area occupied by the devices is large. The powder material drying and cooling integrated device is of a vertical structure and sequentially comprises a feeding box, a drying box, a cooling box and a discharging box from top to bottom. The top of the feeding box is provided with a feeding inlet, the drying box is provided with a heating fluid inlet pipe, a heating fluid outlet pipe, a transverse flow air inlet pipe, a transverse flow air outlet pipe and drying box heat exchange sheets which heating fluids flow through. The cooling box is provided with a cooling water inlet pipe, a cooling water outlet pipe and cooling box heat exchange sheets which cooling water flows through. The discharging box is provided with a discharging port. The powder material drying and cooling integrated device can meet the requirements for drying and cooling of the powder materials in the heat exchange sheets, and is small in occupied area and high in heat exchange efficiency.

Description

technical field [0001] The invention relates to a drying and cooling device for powder materials, in particular to an integrated device for drying and cooling powder materials, which belongs to the technical field of energy saving and environmental protection. Background technique [0002] In industrial production, as an important raw material or product, powder materials often need to be dried or cooled before storage and packaging. Drying is to remove trace moisture contained in powder materials, and cooling is to ensure that the powder The bulk material has a sufficiently low temperature during packaging to avoid moisture absorption, agglomeration and pulverization of the material. [0003] In the drying and cooling process of powder materials, the materials are generally dried and dehydrated by the drying equipment first, and then enter the cooling section for cooling treatment. The drying and cooling are completed in different equipment, so it not only brings higher ene...

Problems solved by technology

[0003] In the drying and cooling process of powder materials, the materials are generally dried and dehydrated by the drying equipment first, and then enter the cooling section for cooling treatment. The drying and cooling are completed in different equipment, so it not only brings higher energy consumption, and the equipment occupies a large area, and the investment cost also increases accordingly; at present, the commonly used solid material drying equipment in the market is mainly a dryer, which not only occupies a large area, but also has a low utilization rate of energy; powder As a new type of powder cooling equipment, flow cooler has the advantages of high heat exchange efficiency, low energy consumption and small footprint, but it does not have the function of drying
