Self-sealed drainer of pipe bundle drier

Abstract

The invention discloses a self-sealed drainer of a pipe bundle drier, and belongs to the field of mechanical equipment. The drainer comprises a hollow half shaft placed in an end seal at the water outlet end; the circumference of the hollow half shaft is provided with a plurality of condensed water drain holes; an involute condensed water guide plate is led out of each condensed water drain hole along the external circle of the hollow half shaft; the involute condensed water guide plate is welded on the inner wall of the end seal; a drain groove is formed between the involute condensed water guide plate and the external circle of the hollow half shaft; and a cover plate is welded on the drain groove. According to the self-sealed drainer, the condensed water is in the drainer all the time in the whole rotation period of a pipe bundle so as to form water seal per se; the vapor does not pass through the drainer so that the vapor has no loss; and meanwhile, the condensed water does not form return flow in each drainer, so the drain amount of the condensed water is high, and the drying effect of materials is better.

Description

Technical field [0001] The invention belongs to the field of mechanical equipment, in particular to a self-sealing drain of a tube bundle dryer. Background technique [0002] The tube bundle dryer is a tube heat exchange device, mainly used in the drying of by-products in corn deep processing, including fiber, gluten, germ, and corn feed. The main structure of the tube bundle dryer is composed of tube bundles, shells and transmission devices. The tube bundle is the main body of the dryer, which is formed by expanding and connecting tube sheets at both ends with a number of heating tubes. In addition, the tube plates at both ends are welded and connected with the head with a hollow half shaft. A number of small holes are opened on the circumference of the hollow half shaft. One end of the hollow half shaft is the heating steam inlet, and the other end is the condensation water outlet. The tube bundle dryer drives the tube bundle to rotate through the transmission device. The wet...

AI Technical Summary

Problems solved by technology

In every rotation cycle of the drainer, a large part of the condensed water will flow back, which reduces the discharge of condensed water, affects the drying effect of materials, and reduces the efficiency of steam use. At the same time, some steam will flow from the drainer Running out of the middle, resulting in the waste of steam, these two aspects have increased the consumption of steam by the user unit, and increased the production cost of the user unit
