Air inlet and feeding device of drying machine

Abstract

The invention discloses an air inlet and feeding device of a drying machine, which is used for the drying machine. The drying machine comprises a cylinder body, wherein the cylinder body comprises aninner cylinder body, a middle cylinder body and an outer cylinder body, wherein the inner cylinder body, the middle cylinder body and the outer cylinder body are integrally formed in a coaxial sleeving manner, and a plurality of spiral plates are uniformly distributed and arranged on the inner surrounding surface of the front end of the inner cylinder body; the air inlet and feeding device comprises a housing, an air inlet pipe and a feeding pipe, wherein the air inlet pipe is arranged on the front end surface of the housing, and also comprises a material conveying device, the material conveying device is arranged on the periphery surface of the front end of the inner cylinder body, feeding openings are uniformly distributed and formed in the periphery surface of the front end of the innercylinder body, and are located between the spiral plates; and each feeding opening comprises a front edge, a rear edge, a left edge and a right edge, wherein the lower end of the feeding pipe is arranged on the side of the housing, materials entering the feeding pipe can enter the inner part of the front end of the inner cylinder body through the material conveying device and the feeding openings, and the housing is fixed through a bracket. The air inlet and feeding device for the drying machine is long in service life, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a dryer, in particular to an air inlet and feeding device for the dryer. Background technique [0002] An existing drying machine comprises an air inlet and air inlet device, a cylinder body, a discharge device and a driving device. The cylinder body includes an inner cylinder body, a middle cylinder body and an outer cylinder body, and the inner cylinder body, the middle cylinder body and the outer cylinder body are coaxially fitted into a whole. The outer cylinder is located on the driving device, the air inlet and air feeding device is located at the front end of the cylinder, and the discharge device is located at the rear end of the cylinder. Spiral plates are evenly distributed on the inner peripheral surface of the front end of the inner cylinder body. The air inlet and feeding device includes a housing, an air inlet pipe and a feeding pipe. The front end of the inner cylinder is located in the rear end of the housing,...

AI Technical Summary

Problems solved by technology

Since the feed pipe is located in the center of the shell, the high-temperature hot air rushes to the lower part of the feed pipe first, so that the lower part of the feed pipe is baked by high-temperature hot air for a long time, which is easily damaged, has a short service life, and needs frequent replacement. This not only increases the production cost, but also the replacement work is extremely troublesome

At the same time, since the feed pipe is located in the center of the casing, the passage of high-temperature hot air entering the inner cylinder is blocked, and the resistance increases, thus increasing the power consumption of the fan.
