Abstract
A drying system of an airflow dryer comprises an air filter, an air heat exchanger and a cyclone separator which are sequentially connected. The air filter, the air heat exchanger and the cyclone separator are communicated through a drying pipe, and a material throwing device is communicated with the drying pipe; an air outlet in the upper end of the cyclone separator is connected with an induced draft fan, and spiral blades are arranged in the drying pipe; and edges on the two sides of the spiral blades are welded to the inner wall of the drying pipe, and hot air and materials penetrate the positions among the spiral blades. The contact area between the hot airflow and the materials can be increased, and therefore the drying strength of airflow drying can be improved.
Description
Technical field
The invention belongs to technical field of mechanical equipment, particularly relate to the drying duct of DGZQ type pneumatic drier.
Background technology
DGZQ type pneumatic drier is the drying plant being specifically designed to starch such as wet method processing corn, potato class, wheat etc., also may be used for converted starch, albumen powder and requires the dry field of quick-drying thermal sensitivity powdery or laminar material; This drying system is under negative pressure state, utilizes thermal current, makes the wet stock of the granular disperseed, be in drying tube to carry out with thermal current under suspended state conducting heat, mass transfer, finally reach the object of dry wet material.This drying system is made up of air cleaner, air heat exchanger, throwing feeder, drying duct, cyclone separator, exhaust pipe, blower fan etc.; The drying of wet stock mainly completes in drying duct.Because dried material is different, the viscosity of some material is comparatively large, and the laxity of material is poor, and such material is not easy drying; And drying is complete due to material, comparatively large to the pollution of cyclone separator, material easily sticks on the pipeline of cyclone separator discharging opening.
Summary of the invention
The present invention, just in order to overcome above-mentioned deficiency, providing a kind of and increasing the time of staying of wet stock in drying duct, decreasing the setting height(from bottom) of pipeline and complete equipment; And the turbulent flow of thermal current in drying duct can be increased, increase the contact area of thermal current and material, thus enhance the pneumatic drier drying system of the dry tenacity of pneumatic conveying drying.
For realizing the object of the invention, provide following technical scheme: a kind of pneumatic drier drying system, comprise the air cleaner, air heat exchanger and the cyclone separator that connect in turn, three is communicated with by drying duct, throwing feeder is communicated with drying duct, and cyclone separator upper end air outlet connects air-introduced machine, it is characterized in that being provided with helical blade in drying duct, described helical blade both sides of the edge are welded in drying duct inwall, and hot-air and material are passed between helical blade.
As preferably, helical blade adopts and is interrupted welding.
Beneficial effect of the present invention: the present invention increases helical blade in the drying duct of pneumatic drier, thermal current is helically moved along helical blade in the duct, because material can move with thermal current, the time of staying of wet stock in drying duct can rise appreciably, and decreases the setting height(from bottom) of pipeline and complete equipment; And the turbulent flow of thermal current in drying duct can be increased, can make material dispersion further in thermal current like this, increase the contact area of thermal current and material, thus enhance the dry tenacity of pneumatic conveying drying.
