A dynamic feedback measurement and control platform for research on fabric drying technology in clothes dryers

Abstract

The invention discloses a dynamic tracing measuring and controlling platform which is used for carrying out signal acquisition on various parameters (air temperature and humidity, air flow speeds and textile temperature and humidity) of all parts in a clothes dryer, regulating and controlling all drying factors (heating wire power, air quantity, rotary speeds, and moisture content of decomposition points), and accurately finishing a drying procedure according to user requirements, and is applicable to researches in the aspects of a textile drying mechanism, drying energy consumption, drying quality, optimization of the drying procedure and the like. The measuring and controlling platform mainly comprises the following parts: the drying of the textiles in the clothes dryer relates to various parameter signal acquisition modules; the drying of the textiles in the clothes dryer relates to various drying factor continuous regulation and controlling modules; various parameter setting, feedback regulating and controlling and storage and display interfaces are arranged in the clothes dryer. By the aid of the measuring and controlling platform, the problem that various parameter procedures of an existing clothes dryer cannot be continuously adjusted is solved and the difficulty of directly testing the self temperature and humidity of the textiles in the clothes dryer is also overcome.

Description

technical field [0001] The invention relates to a dynamic feedback measurement and control platform for the research of fabric drying technology in a clothes dryer, which can not only be used for the research of the fabric drying mechanism in the clothes dryer, the analysis of the relationship between each setting parameter of the clothes dryer and the drying quality of the fabric, It can also be applied to the drying program optimization and drying process improvement of drying equipment such as household thermoelectric direct discharge dryers, household condensation dryers, industrial dryers, and dyeing and drying processes in the fabric production process. research and product development. Background technique [0002] With the advancement of science and technology, laundry has been basically modernized, while clothes drying is still in the traditional stage of hanging and drying. However, with changes in life concepts, living environment (deterioration of living space a...

Problems solved by technology

[0004] Moreover, the current research method on fabric drying mainly adopts the method of conducting large-scale experiments on specific materials, which not only wastes manpower and material resources, but also has the problems of poor universality and large random errors in its conclusions, and it is difficult to extend to other fabrics or In terms of drying level (the root cause of these problems is that we do not understand the thermal mass change of the fabric drying process and the internal structure of the fabric); at the same time, the essence of the fabric drying process is that the fabric with a certain moisture content and the hot air perform thermal Coupling process, the process mainly includes the change law of fabric temperature, fabric moisture content, air temperature and humidity and removal rate, heat and mass exchange between fabric and air, etc.

Therefore, in order to completely solve the problem of poor versatility of the drying model, it is necessary to study the thermophysical characteristics of the fabric drying process, the thermophysical characteristics of the drying environment and the coupling laws of the two, the heat and mass exchange laws in the fabric, and the fabric drying process. In-depth research on microscopic changes and other aspects to master the law of its process behavior changes
