A heating device for washing and dyeing equipment

Abstract

The invention discloses a heating device of a washing and dyeing device. The heating device is located outside an outer barrel. The inner space of an arc-shaped heating cavity of the heating device is portioned into a plurality of heating areas by partition plates in the circumferential direction, and the heating areas are arranged at intervals in the axial direction. The partition plates in the circumferential direction form interval areas between the adjacent heating areas. An air inflow channel is arranged on the tops of the two sides of each heating area and is communicated with the top of the heating area. A plurality of axial partition plates are arranged in each heating area and divide the heating area into a plurality of subareas extending in the axial direction. The wall faces of every two adjacent subareas are provided with through holes through which the adjacent subareas can be communicated. The partition plates, on the two sides of each interval area, in the circumferential direction are provided with through holes same as the subareas of the corresponding heating areas adjacent to the interval area. One end of the air inflow channel located on the tops of the two sides of the heating cavity is communicated with a steam inflow pipe through a pipeline. The bottom of the other end of the heating area located at the bottom of the heating cavity is communicated with a water outflow pipe. The heating device is long in service life, good in heating effect and capable of reducing washing and dyeing cost and improving washing and dyeing effects.

Description

technical field [0001] The invention relates to washing and dyeing equipment, in particular to a heating device for washing and dyeing equipment. Background technique [0002] When the washing and dyeing equipment is working, it is necessary to heat the washing liquid and / or dyeing liquid in it, so as to keep the temperature of the washing liquid and / or dyeing liquid within an appropriate range, so as to ensure better washing and dyeing quality. [0003] The heating device of the existing washing and dyeing equipment is generally placed at the bottom of the inner side of the outer tub of the washing and dyeing equipment, mainly including a heating elbow. The steam inlet of the heating elbow is connected with the steam input pipe, and the outlet is connected with the condensate outlet pipe. When working, the steam enters the heating elbow from the steam inlet, and in the bending pipe, it passes through the wall of the heating elbow to exchange heat with the washing liquid and...

AI Technical Summary

Problems solved by technology

[0004] Although this heating device can basically realize the heating work of the washing liquid and / or dyeing liquid, it still has deficiencies, for example: 1. The heating elbow is arranged on the inner bottom of the outer barrel, which will occupy the inner space of the outer barrel. In the case of a large amount of washing and dyeing, it is necessary to increase the inner space of the outer barrel, and the corresponding amount of washing liquid and / or dyeing liquid will increase accordingly. While increasing the water ratio, it will cause waste of dyes, thereby increasing the cost of washing and dyeing

2. The heating elbow is soaked in the washing solution and / or dyeing solution in the outer barrel, which is easy to be corroded and has a low service life

3. If the heating elbow is placed in the outer barrel, during dyeing and washing, the wool and thread ends falling off the fabric will gather or hang on the heating elbow, and the dye solution remaining on it is difficult to clean , which will ultimately affect the quality of subsequent washing and dyeing (for example, when changing dye solutions of different colors, the residual dye solution will mix with the replaced dye solution, resulting in a change in the color of the replaced dye solution, which will eventually affect the quality of washing and dyeing); 4 , The side wall of the outer barrel is made of thin metal plate, the heat dissipation speed is fast, and the heat loss is relatively serious
