Description

A heated air circulation water conservancy diversion drying device for plaster production

Technical Field

The utility model relates to a hot air drying device, especially a heated air circulation water conservancy diversion drying device for plaster production.

Background

In the production process of the plaster, a drying procedure is needed after the plaster is coated on the back lining cloth. The existing drying devices generally adopt two forms to dry the plaster. 1. Drying is carried out in a manner of arranging a heating plate in the drying tunnel. 2. And drying by adopting hot air. The first heating plate drying method has the disadvantages that the heating plate is generally disposed right above or below the plaster, and the heating plate has poor heat exchange capacity with air, so that the upper and lower surfaces of the plaster are heated unevenly during the drying process, and the drying quality of the plaster is unstable. Meanwhile, in order to ensure the temperature in the drying tunnel, the steam produced by drying with poor air fluidity in the drying tunnel is difficult to discharge, and the drying efficiency is low. In addition, the problem of the hot air drying form is that the traditional hot air drying device has a large local air pressure effect on the surface of the plaster during drying, and the plaster has high fluidity due to high temperature in the drying process, and is easy to migrate under the action of large air pressure, so that the plaster becomes uneven on the backing cloth, and the quality of the plaster is seriously affected.
