Energy-saving and water-saving drying drum for printing and dyeing

Abstract

The invention discloses an energy-saving and water-saving drying drum for printing and dyeing. The energy-saving and water-saving drying drum comprises a left spindle nose, a drum body, a left seal, a right seal and a right spindle nose, the drum body is fixedly connected between the left seal and the right seal, a guide drum is of sealed cavity structure, and two ends of the guide drum are connected with the middles of the left seal and the right seal respectively. The guide drum is also of elliptical structure. Gaps are formed between the outer wall of the guide drum and the inner wall of the drum body as well as between the wall of an inner hole of the left seal and the wall of an inner hole of the right seal. The left spindle nose, the drum body, the left seal, the right seal, the right spindle nose and the guide drum are made of stainless steel. The energy-saving and water-saving drying drum is characterized in the a baffle is arranged on the outer side of each of the left seal and the right seal, the baffles form sealed cavities with the left seal and the right seal respectively, and heat-insulation lining is filled in the cavities. The raw material of the heat-insulation lining is any one of a composite magnesium silicate heat insulation plate, rubber-plastic sponge, polyethylene or polystyrene foam, glass wool, rock wool and polyurethane foam. The energy-saving and water-saving drying drum is high in heat exchange efficiency, low in energy consumption and capable of greatly saving water.

Description

technical field [0001] The invention relates to the field of printing and dyeing machinery, in particular to a drying cylinder for printing and dyeing. Background technique [0002] The drying cylinder for printing and dyeing is a drying equipment for printing and dyeing. The drying cylinder for printing and dyeing in the prior art includes a left shaft head, a cylinder body, a left head, a right head, and a right shaft head. The cylinder body is fixedly connected to the left head and the right seal. Between the heads, the left shaft head is fixedly connected to the left side of the left head, and the right shaft head is fixedly connected to the right side of the right head. When in use, steam enters the cylinder from one side of the shaft, flows through the interior of the cylinder, and flows out from the other side of the shaft. During this process, heat exchange is completed, and part of the steam is converted into water. This type of drying cylinder for printing and dye...

AI Technical Summary

Problems solved by technology

This type of drying cylinder for printing and dyeing has the following defects: First, the internal space of the cylinder is relatively large, and the steam cannot be discharged after fully exchanging heat with the cylinder wall, resulting in large heat loss and high energy consumption; The head, right head, and right shaft head are generally iron parts, which are easy to rust and pollute the printing and dyeing water. Therefore, it is often necessary to replace the printing and dyeing water, resulting in a large waste of water resources
