Heat insulation method for cheese dyeing machine

Abstract

The invention discloses a heat-preserving method used for a cheese dyeing machine, which adopts a high-pressure gasless spraying machine to spray an industrial Delta-T-typed heat-insulating coating on the surface of the cheese dyeing machine, and forms a compact heat-insulating and heat-preserving coating layer with the thickness of 1.5 to 5 mm on the surface of the cheese dyeing machine. The heat- preserving method used for the cheese dyeing machine is applicable to moist working environment, has remarkable heat-insulating, heat-preserving and energy-saving effect, quick construction speed and good anti-corrosion performance, and is convenient for device construction, detection and maintenance.

Description

technical field [0001] The invention relates to a heat preservation method, in particular to a heat preservation method for cheese dyeing machines. Background technique [0002] my country is a big country in the textile industry, and the output of major textile products has ranked first in the world so far; according to statistics, by 2005, there were 1,778 textile printing and dyeing enterprises above designated size in my country, which can be described as a large scale. However, according to the survey results, the dyeing and finishing equipment of most of these printing and dyeing enterprises is not equipped with energy-saving facilities or the energy-saving facilities are not fully equipped, the thermal efficiency is low, a large amount of heat energy is lost in vain, and the consumption of steam is greatly increased. [0003] The maximum working temperature inside the high-temperature and high-pressure cheese dyeing machine is as high as 135°C, which is quite differen...

Problems solved by technology

Because this type of insulation material will improve the thermal conductivity after being damp, thereby reducing the insulation effect; therefore, this insulation method must ensure that the insulation layer is not damp and keep the insulation material dry.

The cheese dyeing machine works in a relatively humid environment. When the cylinder head is opened after dyeing a cylinder of yarn, a large amount of water vapor will overflow, which intensifies the humidity of the environment.

Therefore, if the cheese dyeing machine adopts this traditional heat preservation method, the heat preservation layer is easy to get damp, and it is difficult to achieve the ideal heat preservation effect.

In addition, since there are many throats, pipes and various control valve bodies distributed on the surface of the outer cylinder wall of the cheese dyeing machine and the outer surface of the cylinder head, it is necessary to avoid these when using the traditional heat preservation method to wrap the heat insulation material. device, which brings a lot of inconvenience to construction and equipment maintenance

Another point is that in this traditional thermal insulation method, the thickness of the thermal insulation layer is generally at least 30-50mm in order to achieve a certain thermal insulation effect, which increases the occupied area of ​​the equipment to a certain extent. Under the premise of satisfying the performance of the equipment, the floor area of ​​the equipment should be reduced as much as possible, so as to maximize the energy-saving benefits

[0005] Based on the above three reasons, the application and promotion of traditional thermal insulation technology on cheese dyeing machines are seriously restricted.
