Conductive heating type drying bin

Abstract

The invention provides a conductive heating type drying bin which comprises a drying bin body and a metal pipe. The drying bin is a double-cone drying bin or a single-cone drying bin or a roller drying bin. Two ends of the metal pipe are inserted into the upper and lower corresponding hot melting holes of the drying bin body, and the a head of the metal pipe and the bosses of the hot melting holes are fixedly welded into a whole. The bosses of the hot melting holes have certain widths and thicknesses, and the bin body of the thin metal plate with the hot melting holes has low requirements on the welding process. Under the supporting effect of a hot melting hole taper sleeve thick wall layer, the metal pipe has high resistance and high torsion resistance, the welding position between the metal pipe and the bosses of the hot melting holes cannot be damaged under the shaking stress effect of the metal pipe, and the service life of the conductive heating type drying bin is prolonged.

Description

[0001] The invention relates to a drying bin used in conjunction with drying equipment, in particular to a conduction heating type drying bin. Background technique [0002] Chinese Patent Literature Publication No. CN105222577B Stereo Heating Type Vacuum Drying Chamber, CN105318680B Stereo Heating Type Double Cone Vacuum Dryer. tube); the two ends of the heat dissipation pipe are inserted into the corresponding openings of the inner shell (equivalent to the drying warehouse body of this application); the bonding position of the heat dissipation pipe and the inner shell is welded as a whole. [0003] Chinese Patent Literature Publication No. CN105423739B is a heat pipe drying bin that can utilize waste heat, and CN105444551B is a rotating drying bin with a cooling section, and the two ends of the heat dissipation standpipe (equivalent to the metal pipe of the present application) are inserted into the corresponding openings on the drying bin body. ; Use a welding machine to wel...

AI Technical Summary

Problems solved by technology

Under the sloshing stress of the metal pipe, the weld between the heat dissipation pipe (equivalent to the metal pipe in this application) and the warehouse body is easily damaged and leaks. The leak point is not easy to check and repair. It caused the scrapping of the dry warehouse and made it unusable

[0005] In order to have high resistance and high torsion resistance performance between the drying chamber body and the metal pipe, the only way to increase the thickness of the metal plate of the drying chamber body is to increase the connection area between the chamber body and the heat dissipation pipe, so that the drying of the thick metal plate chamber body The production cost of the warehouse increases; the weight of the drying warehouse increases, and the power consumption required for the operation of the drying warehouse also increases
