Humidity detection and intervention device for industry dryer

Abstract

A humidity detection and intervention device for an industry dryer comprises a device body, a valve assembly and an industry dryer controller. The interior of the device body is provided with an inlet chamber, a measuring chamber and a blast chamber, a humidity detection element connected with the industry dryer controller is installed at a measuring air exhaust opening of the measuring chamber, the other side of the measuring chamber is provided with a drying air inlet, and a heating mesh is arranged at the drying air inlet; an air blower is arranged in the blast chamber; data detected by the humidity detection element can perform intervening on the industry dryer controller and then change the working progress of the dryer, and the industry dryer controller can reversely control the valve assembly, the heating mesh and the air blower to dehumidify the humidity detection element. According to the humidity detection and intervention device for the industry dryer, the humidity detection element is reversely dehumidified, the accuracy and sensitivity of the humidity detection element are guaranteed, therefore, the humidity detection element which cannot work temporarily due to the high humidity can be quickly recovered, the control of the industry dryer can become more intelligent, and the advantages of being simple in structure, convenient to install and low in cost are achieved.

Description

technical field [0001] The invention relates to an industrial dryer capable of drying wet objects, in particular to a humidity detection and intervention device for the industrial dryer. Background technique [0002] At present, the drying process of industrial dryers on the market is mostly time-controlled, and it is difficult to determine the drying time of objects of different materials and humidity. It often happens that the objects are not completely dried, or because the drying time is too long, the objects The material and quality are damaged. For this reason, a dryer that uses humidity to intervene and adjust the drying time to a certain extent appeared later, and intervened in the drying program by detecting the humidity of the exhaust port to improve the drying efficiency. However, these dryers also have a disadvantage. If the moisture content of the object is too high, it will have a great impact on the accuracy and sensitivity of the humidity detection element d...

AI Technical Summary

Problems solved by technology

It intervenes in the dryer through the parameters obtained from the humidity sensor, but when the humidity is too high, it has a great impact on the accuracy and sensitivity of the humidity sensor, so it is prone to incorrect humidity detection. In the accurate situation, the object to be dried will be damaged due to the drying time being too long
