Device for uniform air distribution in a tunnel dryer

Abstract

For this purpose, a device was developed in 3D that ensures the uniform distribution of the thermal agent over the entire geometric volume of the tunnel. The disadvantages of the existing technical solutions consist in the fact that they have a very limited period of operation of the working organs, they have a low yield in terms of air distribution efficiency, they are complicated constructions, all these factors complicating their service and requiring increased expenses for maintenance. The device for the uniform distribution of the air flow in the dryer-tunnel consists of: the connecting rod-crank mechanism, which transmits the oscillatory movements of the mobile metal frame mounted in the air flow passage body, in which the ribbed vanes are installed, fixed with one end on a fixed metal frame, and with the other end moving vertically synchronously with the help of the mobile metal frame, coupled with it by means of cylindrical couplings.
