Abstract
The utility model provides an online moisture detector which can automatically detect the granular, powder, filamentous materials with moisture content of between 8 and 35 percent online. The detector of the utility model adopts a computer technique and a microwave technique to achieve online automatic detection, the material entrance of the online moisture detector is funnel-shaped, which can avoid the influence on detection precision caused by the instability of materials, and the bypass materials flow from one side of the detection channel. The utility model has the advantages of simple structure, convenient operation, immediate and rapid display of the detected material moisture, which provides reliable proofs for material moisture control.
Description
Affiliated technical field
The utility model relates to particle or powdery, the online water content detection of filamentary material (moisture is between 8%～35%), can be widely used in grain processing, grain heat-drying, the material online automatic detection of tobacco processing and other fields.
Technical background
Thereby in fields such as grain processing, need to detect the moisture of material at present and controlled the requirement that reaches processing technology, for realizing that this requires people to adopt manual method or employing electric-resistivity method, capacitance method reaches the purpose of fast detecting with it, but there are shortcomings such as accuracy of detection is low in said method, can not satisfy well fast or the demand that detects automatically.
Summary of the invention
Low for overcoming existing moisture detection apparatus accuracy of detection, can not realize the deficiency of online detection, the purpose of this utility model provides a kind of online moisture detector, but the graininess powdery of online automatic detection 8%～35% or thread material require to provide instant data to reach to realizing that automation control appliance provides the reliable detection instrument for realizing product processing technique.
The technical scheme that its technical matters that solves the utility model adopts is: this detector is to be installed in the discharging opening of grain drying tower or other is surveyed on the streams mouth of pipe fully, and devices such as the computing machine that is connected by its, display, data entry keyboard realize surveying fully the material moisture online automatic detection.Survey material fully and flow into this detector by interface, this detector profile is similar to a square body, above casing, be provided with three and be the funneling material collection mouth of domatic, collecting a mouthful one side of being opened wide is rectangle by-pass flow passage, the by-pass flow channel sized, can set according to surveying material output fully, collect a mouthful below and be provided with the sense channel that is shaped as rectangular parallelepiped that is shaped as 120 * 60 * 270mm, in the middle of these rectangular parallelepiped both sides, leave the rectangle Microwave Measurement mouth of a 65 * 45mm, on the Microwave Measurement mouth of both sides, microwave emitter and microwave receiver are installed respectively, realize the purpose of Microwave Measurement, microwave emitter is provided with the trumpet type emitting antenna, microwave isolator, microwave oscillator, they are fixed on sense channel one side by curing and Luo bolt, use the same method and will be provided with the trumpet type receiving antenna, microwave detector, the microwave receiver of microwave amplifier is fixed on the opposite side of sense channel.The input of microwave emitter and microwave receiver, output signal and power supply are connected on computing machine etc. by cable.Neither one horizontal shaft type material is regulated the control turnover panel in sense channel bottom, and this turnover panel is to realize free movablely by the axis hole of sense channel bottom, and the joystick of this turnover panel is with on the control position of the solid respective side at the by-pass flow passage of Luo silk.Adopt this device can realize the online automatic detection material moisture,, go out corresponding material moisture by the display instant playback when microwave attenuation signal that material is produced during by the Microwave Measurement passage after corresponding ratio is handled by computing machine.
Owing to adopted above-mentioned design proposal, the beneficial effects of the utility model are: simple in structure, easy to operate, the moisture of detected material can fast show immediately, for the control material moisture provides reliable basis.
