The online moisture content tester of roller dryer
The present invention relates to a kind of online moisture content tester, the online moisture of specifically a kind of roller dryer is surveyed
Trial assembly is set.
Grain moisture content is an important factor for influencing grain quality, and grain drying is the important link of grain security storage.Rolling
Cylindrical dryer is the production process of a grain continuous drying, and ceaselessly rotary furnace drying works in roller drying storehouse.Its flow is
Wet grain is sent into roller drying storehouse first, the safe moisture drying of grain reaches 14% or so rear discharge roller drier.Herein
In the process, grain moisture content on-line checking and control are to restrict the core technology of grain drying system.Grain measurement of moisture content method master
It is divided into non-destructive testing and damages detection, non-destructive testing does not destroy grain itself character, passes through its physics, optics and chemical characteristic
Moisture is measured, detection is damaged and then needs to carry out physical crushing to grain or bring it about chemical change and original shape cannot be kept
State.The importance and complexity for analyzing the graininess grain on-line determination of moisture during the drying process, since influence factor is multiple
Miscellaneous, conventional method is difficult to realize the online moisture of grain and quickly measures, and the online moisture measurement of grain depends on import equipment more at present.
The problem to be solved in the present invention is to overcome the shortcomings of the prior art, provide a kind of roller dryer
Line moisture content tester is lossless online moisture measurement, and wireless sensor is utilized between moisture measurement equipment and display device
Network technology improves the reliability of online moisture measurement system.
In order to reach above-mentioned purpose, what the present invention was achieved through the following technical solutions：A kind of roller dryer it is online
Moisture content tester includes barrel, moisture content detection device, data line, flange, battery, wireless transmitter module, wireless receiving module,
Display device, attemperator.
The barrel is the metal tube of cylindrical shape.

2, there are one partition boards for the inside of barrel.
3, the cylinder of partition board and barrel is connected to one.
The diameter of the barrel is 50-280mm, and the length of barrel is 80-580mm.
There is attemperator outside the cylinder of the barrel.
1, attemperator is played to grain insulation effect in barrel and barrel.
, attemperator making material be heat-preservation cotton resin plastics or rubber.
For the grain detected into behind the inside of feeding cylinder, barrel plays heat preservation, windproof, vibration proof to the grain detected
Effect, influencing the complex effects factor of the online water content detection of grain reduces, and grain can quickly obtain moisture inspection in barrel
Survey the quick moisture measurement of device.
The flange is fixed below barrel on position；What the cylinder of flange and barrel was connected to one.
The barrel is fixed on by flange on the warehouse of roller drying storehouse；Barrel be with roller drying storehouse together
1, a bore and the equirotal round mouth of barrel outer diameter are opened on the warehouse of roller drying storehouse, on the warehouse of roller drying storehouse
The bore of round mouth is 50-280mm；Flange is fixed on round mouth.
2, the flange on the flange on barrel and roller drying storehouse warehouse on round mouth, is bolted and is integrated.
3, after installing gasket between two flanges, two flanges are bolted sealing.
The moisture content detection device is mounted on the upper surface of barrel internal partition；Moisture content detection device plays in detection barrel
The detection of the grain moisture content in portion acts on.
The moisture content detection device is the grain's moisture teller of resistance-type or capacitive measuring grain moisture content
1, the principle of capacitive grain's moisture teller is the contrasted between solid dielectric using cereal as capacitor, the circle of capacitor
When distance between logical pole plate and circle through post pole plate remains unchanged, when grain is put into two interpolars, the size of grain moisture content causes pole
Between medium electrostrictive coefficient variation, the capacitance of capacitance sensor also changes, and measures the water content of grain indirectly.
2, the grain's moisture teller system resistance-type of resistance-type measures, and is corresponding with grain moisture content variation by measuring
Resistance value variation and measure moisture.
The battery, wireless transmitter module are mounted below barrel internal partition.
The wireless transmitter module is connected to moisture content detection device by data line.
The battery provides electric energy to wireless transmitter module, moisture content detection device.
1, battery is disposable battery, or be rechargeable battery.
2, rechargeable battery can be charged by wireless charging device.
The wireless receiving module is connected to display device by data line.
1, wireless receiving module and display device are fixedly mounted on the holder of dryer.
2, the installation site of wireless receiving module and display device is fixed.
The wireless transmitter module is connected by data line with moisture content detection device.
The moisture content detection device output water content detection data-signal sends out water content detection number by wireless transmitter module
It is believed that number, wireless receiving module receives water content detection data-signal.
1, the water content detection data-signal that wireless receiving module receives is to be conducted to display device to show by data line.
2, the water content detection data-signal that wireless receiving module receives either does roller dryer by data line
Grain heat-drying control system core data effect.
In the Grain Drying Process that the grain heat-drying control system of roller dryer is detected according to moisture content detection device
The grain moisture content data of different drying stages, regulate and control roller dryer roller drying storehouse rotating speed and grain drying need
The long short time.
The present invention has the advantages that with existing online moisture content tester ratio：A kind of roller dryer it is online
The design of moisture content tester is simple, and converting the online water content detection of dynamic grain to the online moisture of static grain surveys
Examination, for grain into behind the inside of feeding cylinder, barrel plays the role of heat preservation, windproof, vibration proof to the grain detected, influences grain
The complex effects factor of online water content detection reduces, and grain can quickly obtain the fast of online moisture content detection device in barrel
Speed measures, and improves the moisture accuracy of the online water content detection of grain, the lossless online moisture measurement of grain improves grain
