Turning plate material tray for material transfer

Abstract

The invention relates to a turning plate material tray for material transfer. The turning plate material tray includes turning plates distributed radially with a rotating shaft as a center, each turning plate is in a fan shape, the turning plates turn over around supporting rods so as to ensure that wet materials evenly fall into a lower layer material tray from an upper layer material tray, and aguide rail is provided with a gap with a cross section at one end and a curved surface at one end. When a low-temperature material dryer is started, the material trays of each layer are driven to rotate synchronously through the rotating shaft; the turning plates of the upper layer material tray turn downwards by taking the supporting rods as shafts under the action of gravity when rotate throughthe gap of the guide rail, and the actions of overturning, climbing and climbing horizontally are completed in turn. The wet materials on the turning plates further fall onto the lower layer materialtray, so that the transfer of the wet materials on the turning plates from the upper layer material tray to the lower layer material tray is realized.

Description

technical field [0001] The invention relates to the field of low-temperature material drying, in particular to a flap material tray used for material delivery of a low-temperature material drying machine. Background technique [0002] At present, there are more and more scenes that require hot air drying in the market, such as tobacco drying, grain drying, medicinal material drying, fruit and vegetable drying and other processing processes, and the reduction and harmless treatment of waste such as wet materials. In order to make the material dry quickly, high-temperature hot air, flue gas, heat transfer oil or hot steam are mainly used for high-temperature drying. The disadvantages of high-temperature drying are complex installation conditions, high energy consumption and more exhaust gas, which needs to be collected and treated. And the working environment temperature is high, there are certain potential safety hazards. [0003] In order to overcome the above problems, the...

AI Technical Summary

Problems solved by technology

[0005] 1. As the moisture content of the wet material decreases during the drying process, the internal moisture is not easy to precipitate to the surface, and the drying rate will decrease. The wet material on the tray needs to be stirred with tools to complete the heat exchange with the hot air, otherwise the wet material will The surface of the material is fully exposed to the hot air to distribute moisture. The heat utilization rate of wet material drying is low and the drying effect is poor.

[0006] 2. When wet materials are transferred from the upper tray to the lower tray, tools are needed to collect the materials, which increases the complexity of the equipment

In addition, if the fineness of the collection tool is not enough, it is easy to keep the wet material on the tray, which increases the difficulty of equipment maintenance
