Oven drying method is that tradition is also most direct humidity measuring method, and measurement accuracy is higher.But it takes longer and applies model
It encloses relatively narrow, has damage to measured object, be not suitable for on-line measurement, and measurement accuracy is by drying time and the shadow of the material stirring uniformity
It rings.
Infra-red method can realize on-line measurement, but its measurement result by tested material surface color and shape influenced compared with
Greatly.And between measured object and detector the factors such as variation of distance influence, and the transmittance of infrared ray is poor.In addition, detection
There is certain temperature drift and time drift in device, the repeatability of measured value is made to be affected during the work time.
Developed countries had begun working on the detection control technology that substance moisture content content is carried out using microwave in recent years.
The country is in this field or blank.Therefore, energetically seeking a kind of not only science but also safe flour water always both at home and abroad
Sorting measurement equipment.
Invention content
The present invention provides a kind of powdery hygrometric machine, and realization quickly and accurately measures powdery on the production line of high-speed production
The humidity and water content of substance.
Technical scheme is as follows：
A kind of powdery hygrometric machine, including body portion and conveyance part；
Body portion, including main flow pipe, isocon and organic glass detection pipe；
Main flow pipe one end and one end of isocon connect the entrance of flour, the other end and isocon of main flow pipe jointly
The other end pass through machine glass detection pipe unicom；
Machine glass detection pipe both sides are equipped with microwave moisture detection sensor；
Conveyance part, including transmission case, micromotor；
Micromotor is installed on motor installation backing plate, and motor installation backing plate is installed on transmission case body, transmission case case
Body is connected to by transmission case end cap on isocon；
Broken arch axis stirs pipe by bearing in transmission case body, and stretches into isocon；
Broken arch axis connection micromotor main shaft is equipped with broken arch on broken arch axis and turns；Broken arch axis and broken arch have air in turning
Chamber, air chamber are connected and connect air compressor；
It stirs in front of pipe and faces organic glass detection pipe, stir pipe by transmission gear and broken arch axis connection, stir pipe
On spiral propeller is installed.
The method have the benefit that：
1, among no matter measured matter is static or high-speed motion, the present invention can accurately, reliable online high speed detection
Go out the moisture of substance.
2, the present invention accurately, reliable can go out the substance moisture content that high-speed motion substance is flowed through in each moment by on-line checking
Content.
3, the present invention can accurately, reliable detect to be distributed in material surface and the moisture of center portion, and not by material surface
The influence of situation.
4, the present invention carries out the detection of substance moisture content using microwave technology, since microwave signal frequency is high, pace of change is fast,
To the reacting condition and its sensitivity of material mass and moisture.Due to the use of microwave power it is minimum, so will not to measured matter
Any influence is generated, any pollution and injury will not be caused to work-yard and operating personnel.
5, the present invention meets real-time, online, non-contact, the not damaged requirement quickly measured in actual production, design side
Case is rationally easy, and precision is higher, and cost is relatively low, and detection speed is fast and has preferable stability, meets practical application
It needs.
Advantages of the present invention will provide in the description of specific embodiment part below, partly will from the following description
Become apparent, or practice through the invention is recognized.
Description of the drawings
Fig. 1 is the cut-open view of final assembly of the present invention.
Fig. 2 is the enlarged drawing of conveyance part of the present invention.
Specific implementation mode
The following further describes the specific embodiments of the present invention with reference to the drawings.
As shown in Figure 1, the present invention includes two large divisions：Body portion and conveyance part.Wherein, body portion is by leading
Flow tube 1, isocon 2, organic glass detection pipe 3 form.
Main flow pipe 1, isocon 2 entrance connect the entrance of detected object-flour jointly.1 powder of main flow pipe
Matter flows primarily through channel.Isocon 2 shunts fraction flour, and organic glass detection is delivered to by conveyance part
Humidity Detection is carried out in pipe 3.Main flow pipe 1 and isocon 2 are by 3 unicom of organic glass detection pipe, the flour in isocon 2
Organic glass detection pipe 3 is also passed through to be back in main flow pipe 1.
As shown in Fig. 2, the concrete structure of conveyance part, including transmission case 5, micromotor 6.Transmission case 5 is by being driven
Box body 8, transmission case end cap 9 and the broken arch axis 10 being installed in transmission case, broken arch turn 12, transmission gear 14, bearing 15 etc.
Composition.
Micromotor 6 is installed on motor installation backing plate 7, and motor installation backing plate 7 is installed on transmission case body 8, is played
The fixed function of micromotor 6.Transmission case body 8 is connected to by transmission case end cap 9 on isocon 2.Broken arch axis 10 stirs pipe
12 are mounted on by bearing 15 in transmission case body 8, and are stretched into isocon 2.Broken arch axis 10 connects 6 main shaft of micromotor, breaks
Broken arch is installed on arch axis 10 and turns 11, drives broken arch to turn 11 rotations using broken arch axis 10, realizes the broken arch of powder.10 He of broken arch axis
Broken arch has air chamber in turning 11, and air chamber is connected, and connects air compressor.For the situation ineffective in rotation broken arch
Under, strong air flow is formed by air compressor, with the speed more than velocity of sound directly into the occlusion faulty section of granular material, with
The expansion shock wave discharged suddenly, overcomes material static friction, and material is made to restore flowing.It stirs pipe 12 by transmission gear 14 and breaks
Arch axis 10 connects, and stirs and is equipped with spiral propeller 13 on pipe 12.It stirs 12 front of pipe and faces organic glass detection pipe 3, use
In granular material is pushed in organic glass detection pipe 3.
3 both sides of organic glass detection pipe are placed with microwave moisture detection sensor 4.It is produced by microwave moisture detection sensor 4
Raw microwave signal, transfers signals to organic glass detection pipe 3, when tested flour passes through organic glass detection pipe 3, no
It can cause the different variations of microwave electromagnetic field energy parameter in organic glass detection pipe 3, organic glass with the measured matter of water content
Microwave signal in glass detection pipe 3 is made its resonance characteristic change by the disturbance of measured matter, passes through the micro- of the other side
Wave moisture detection sensor 4 detected the microwave signal disturbed in organic glass detection pipe 3, by being examined to energy parameter
Analyzing processing is surveyed, the variation of measured matter real-time density and humidity parameter is finally reduced into.
This product is applied to food service industry, and flour of the moisture less than 13.5% can carry out humidity inspection with this product
It looks into.
