Abstract

The invention discloses a variable air volume heating method with feedback and a device thereof. The variable air volume heating method with feedback is characterized in that comparing the heating temperature and air speed provided practically through a detection device and the heating temperature and air speed required by setting simultaneously; regulating the heating system through a feedback system to achieve the optimum heating temperature; and regulating the air speed through regulating the size of an air gate and / or fan rotation speed. The device implementing the method controls the air gate arranged between the fan and an air pipe through a control system, and regulates the air volume entered into a material bucket through regulating the size of the air gate; or the control system regulates the fan rotation speed to regulate the air volume entered into the material bucket in a unit time, thereby setting the quantity of the air volume entered into the material bucket as required, and reaching the effect of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a heating method with variable air volume and a device thereof with feedback. Background technique [0002] The material drying equipment currently on the market generally uses a blower to deliver hot air to the material barrel through a metal pipe with an electric heating tube inside to dry the material in the barrel. The main components of this type of dryer include fan, electric heating tube, metal Air inlet pipe, electrical control box, metal thermometer, material barrel, upper and lower screens, cover plate, etc., the principle is that the fan blows a certain amount of wind, and when the wind passes through the air inlet pipe, it is heated by the electric heating tube in the air inlet pipe When the temperature reaches the set temperature, it enters the material barrel, and the hot air takes away the moisture in the material particles when passing through the material barrel to achieve the drying effect. [0003] Since the...
