Material guide device of three-barrel drying machine

Abstract

The invention discloses a material guide device of a three-barrel drying machine. The material guide deice comprises a composite cylinder body, a blanking device and a transmission device, wherein the blanking device is arranged at one side of the composite cylinder body; the transmission device is arranged at the lower end of the composite cylinder body; the composite cylinder is sleeved by an outer cylinder body, a middle cylinder body and an inner cylinder body which are of different diameters from large to small in a concentric mode; the inner wall of the outer cylinder body, the middle cylinder body and the inner cylinder body are respectively provided with a screw-type lifting blade; the outer wall of the middle cylinder body and the inner cylinder body are respectively provided with a radial lifting blade; one end of the inner cylinder body is provided with a feed inlet; the other end of the inner cylinder body is provided with a discharge outlet; the discharge outlet is communicated with the feed inlet at one end of the middle cylinder body; a discharge outlet of the middle cylinder body is connected with a feed inlet of the outer cylinder body; the other end of the outer cylinder body is provided with a discharge outlet; and the discharge outlet of the outer cylinder body is provided with the material guide device. The material guide device provided by the invention has the advantages that the discharging is more smooth, the structure is simple, the material guide device is convenient to use, the material can be delivered well by the material guide device in the drying process, and the problem of material blocking for the three-barrel drying machine is solved.

Description

technical field [0001] The invention relates to a three-cylinder dryer, in particular to a material guide device of the three-cylinder dryer. Background technique [0002] Three-cylinder dryers are used in building materials, cement, dry powder mortar, casting and other industries. The structure of the existing three-cylinder dryer includes: a composite cylinder, a feeding device arranged on one side of the composite cylinder and a transmission device arranged at the lower end of the composite cylinder. The composite cylinder consists of three outer tubes with different diameters from large to small. The cylinder body, the middle cylinder body and the inner cylinder body are concentrically assembled, and the inner walls of the outer cylinder body, the middle cylinder body and the inner cylinder body are respectively provided with spiral lifting plates, and the outer walls of the middle cylinder body and the inner cylinder body are respectively arranged There is a radial lif...

AI Technical Summary

Problems solved by technology

The existing three-cylinder dryer does not discharge smoothly, and it is prone to blockage at the discharge port. At the same time, the internal space of the inner cylinder is relatively large, and the materials cannot be conveyed and stirred well during the drying process.
