Plate-shaped thing drying machine

Abstract

A plate dryer, comprising a drying box with a chamber, several heaters with heat radiation and heat dissipation films, at least one fan, movable parts and a controller, the heater with heat radiation and heat dissipation films The controller and the fan are installed in the chamber, and the controller is electrically connected with the fan and the heater with heat radiation film. The dryer can be equipped with multiple groups of plate dryers according to the degree of dryness. In this way, the present invention utilizes the characteristics that each system is independent and adjustable, so that the speed (intensity) of each fan and the temperature (wattage) of the heat source can adjust the temperature of each area according to the needs, and the small fan can The airflow is introduced, and the heat source is evenly conducted through the heater with the heat radiation film in the form of fins; thus, the present invention is a distributed heat convection and heat conduction system, which is highly mobile and can be seen It is required to adjust the temperature of the heat source and the speed of the fan separately, so that the internal heat source can achieve the effect of centralized drying and energy saving.

Description

technical field [0001] The present invention relates to a plate dryer, in particular to a distributed heat convection and heat conduction system, especially a highly mobile system, which can adjust the temperature of the heat source and the speed of the fan according to the needs, and then make the internal heat source A dryer that achieves centralized drying and saves energy. Background technique [0002] The structure of the known dryer, its heat source is realized by the control of such a large and complex process as the central air-conditioning system, and its heat source is only in one area, and a large heat source and a large fan are used to pour hot air into it through the air duct. The heat flow is the hottest at the hot air outlet and the coldest at the end, which makes the heat gradient change and cannot make the temperature uniform; moreover, this type of central air-conditioning system blows the wind in at a fixed speed, and it is difficult to accurately control ...

Problems solved by technology

[0002] The structure of the known dryer, its heat source is realized by the control of such a large and complex process as the central air-conditioning system, and its heat source is only in one area, and a large heat source and a large fan are used to pour hot air into it through the air duct. The heat flow is the hottest at the hot air outlet and the coldest at the end, which makes the heat gradient change and cannot make the temperature uniform; moreover, this type of central air-conditioning system blows the wind in at a fixed speed, and it is difficult to accurately control each area Therefore, the central centralized air conditioner cannot adjust the temperature of each area according to the demand, resulting in differences in the dryness of the upper and lower surfaces and the inside of the dried object, resulting in uneven overall drying degree and limited drying effect, etc. Shortcomings, thereby reducing the subsequent processing quality of the dried object

[0003] Furthermore, in the field of heat dissipation, heat conduction is the most effective heat dissipation method, followed by heat convection, and finally heat radiation. However, all current electric heating products only emphasize heat radiation and ignore the importance of heat conduction. In this way, the heating wire is included in the rod, so that the heat can radiate through the ceramic, but the heat conduction of the ceramic is very poor, so the heat conduction performance of this type of electric heating product is not good.

[0004] Based on the above reasons, the existing dryers generally cannot meet the needs of users in actual use, and it is indeed necessary to further improve the drying methods of the above-mentioned known dryers.
