Improved tube bundle for tube bundle dryer

Abstract

The invention provides an improved tube bundle for a tube bundle dryer, belonging to the field of chemical machinery and equipment. A transmission main shaft, a passive main shaft are weld with an end socket and a tube plate respectively at two ends into a whole; the two sides of a heating tubebank is in expanded joint with tube plates at the two ends, and the middle part is supported by a plurality of supporting tube plates; a material shovel angle iron provided with a straight material shovel and a tilted material shovel is welded and fixed on the circumferences of the tube plates at the two ends and the supporting tube plates; and the material shove angle iron is slantwise welded on the tube plates at the two ends and the supporting tube plates, i.e. an inclination angel is formed between the material shovel angle iron and the tubebank, thus improving the synchronism of the two ends of a main shaft and the torsion resistance of the material shovel angle iron, prolonging the service life of the material shovel angle iron and reducing the maintenance frequency of the tube bundle.

Description

technical field [0001] The invention belongs to the field of chemical machinery equipment, in particular to a tube bundle for a tube bundle dryer. Background technique [0002] The tube bundle dryer is a tube heat exchange device. At present, the starch, alcohol (ethanol) and other industries generally use the tube bundle dryer to dry the materials. The tube bundle is the main body of the dryer, which is made of tube plates at both ends and a number of heating tube expansion tubes. There are several supporting tube plates in the middle of the tube bundle to support the heating tubes; the shovel angle iron is axially welded on the outer ring of the tube plate, and the shovel angle iron is equipped with a straight shovel and an inclined shovel with an axial inclination. The prior art material shovel angle iron is horizontally welded on the tube sheet, parallel to the row tubes (the row tubes are in a horizontal state). The running state of the tube bundle is started first by...

AI Technical Summary

Problems solved by technology

The running state of the tube bundle is started by the transmission end first, and the passive end is driven to start. The interval between them is extremely short. The running state of the shovel angle iron fixed on the tube plate is not synchronized at both ends, and the entire shovel will be twisted. This parallel The anti-twist ability of the set shovel angle iron is relatively poor. The entire shovel angle iron will bear a huge twisting force in an instant. Repeatedly bearing this huge twisting force will cause the shovel angle iron to break and shorten the material. The service life of the shovel angle iron and the breakage of the shovel angle iron require long-term maintenance, which brings great economic losses to the manufacturer
