Description
Technical field
The utility model relates to a kind of analytical instrument, and particularly, the utility model relates to a kind of quick moisture teller of microwave that is used for moisture and volatile matter content content in food, medicine, the chemical industry on-line analysis sample.
Background technology
In the workshop of industries such as food, medicine, chemical industry, may need in one day the routine analysis hundreds of times or thousands of inferior content that removes to measure its moisture or volatility object, be very to be necessary so measure the moisture of sample accurately and rapidly.Traditional moisture teller is to adopt the oven dry weighing method, uses the instrument drying time of this kind method long, is generally 1-3 hour; Use the platinum resistance temperature control, temperature rather than the direct temperature of sample in the control heating chamber are so temperature control is unreliable; Because the precision of balance is low, cannot satisfy the requirement of low moisture content measuring accuracy.Given this, traditional moisture teller can't satisfy the requirement of on-line analysis, only can be used for common lab.
The utility model content
For overcoming above-mentioned shortcoming, the utility model provides a kind of microwave quick moisture teller, this instrument can accurately, fast, automatically be measured the moisture of sample, satisfies the requirement of the online detection of workshop routine analysis of industries such as food, medicine, chemical industry.
To achieve these goals, technical solutions of the utility model are as follows:
The quick moisture teller of a kind of microwave, comprise furnace chamber 1, be arranged at the microwave rf generator 5 of furnace chamber 1 side, be arranged at the monitoring balance on goods and services 6 of furnace chamber 1 bottom, be arranged at the electronic balance 7 of monitoring balance on goods and services 6 belows, it is characterized in that: furnace chamber 1 top is provided with microwave stirrer 3 and infrared temperature sensor 2.
According to the quick moisture teller of a kind of microwave described in the utility model, it is characterized in that the end face that the sidewall of described furnace chamber 1 is formed is a regular polygon.The regular polygon furnace chamber can focus on microwave the heating of sample place fast.
According to the quick moisture teller of a kind of microwave described in the utility model, it is characterized in that described monitoring balance on goods and services is made of metal.Can make microwave focus on the sample place thus, the conduction orientation that can change microwave again makes the sample homogeneous heating
According to the quick moisture teller of a kind of microwave described in the utility model, it is characterized in that a waveguide 4 is arranged between described microwave rf generator 5 and the furnace chamber 1, carry out the microwave conduction by it.
According to the quick moisture teller of a kind of microwave described in the utility model, it is characterized in that the puddler of described microwave stirrer 3 is to be made by metal material, its installation direction is vertical with the microwave direction that microwave rf generator is launched.Can make sample homogeneous heating everywhere thus
According to the quick moisture teller of a kind of microwave described in the utility model, it is characterized in that described infrared temperature sensor 2 is aimed at monitoring balance on goods and services 6.Can monitor sample temperature thus, instrument is adjusted microwave power based on this temperature, has not only guaranteed that heating fast but also guarantee that sample does not have burned phenomenon.
According to the quick moisture teller of a kind of microwave described in the utility model, it is characterized in that the quantity of the sidewall of described furnace chamber 1 is 6～10.
The utility model is compared with traditional moisture teller, the sample analysis process accurately, fast, homogeneous heating, efficiency of heating surface height, The whole analytical process has realized robotization.
Description of drawings
Furnace cavity structure stereographic map in the quick moisture teller of a kind of microwave that Fig. 1 provides for the utility model;
The structure cut-open view of the quick moisture teller of a kind of microwave that Fig. 2 provides for the utility model.
Embodiment
Below, with reference to accompanying drawing, be described more specifically the quick moisture teller of microwave of the present utility model with embodiment.
The structural upright synoptic diagram of the furnace chamber in the quick moisture teller of a kind of microwave that Fig. 1 provides for the utility model.The sidewall of furnace chamber is made up of six faces, and the furnace chamber wall carries out orienting reflex to microwave, make microwave be gathered in balance on goods and services 6 top samples around.
Shown in Figure 2, the structure cut-open view of the quick moisture teller of a kind of microwave that provides for the utility model, the microwave of microwave rf generator 5 emissions imports in the furnace chamber 1 through waveguide 4, and metal puddler 3 has changed the single direction of propagation of microwave, and microwave is propagated in furnace chamber 1 equably.The sexangle microwave cavity of Specialty Design carries out orienting reflex to microwave, make microwave be gathered in balance on goods and services 6 top samples around because balance on goods and services is that metal material is made, so the microwave that focuses on is dispersed in around the sample uniformly.Because this kind design feature of instrument, make moisture in the sample can within a short period of time evaporate to dryness, general sample analysis process can be finished in 5 minutes.
Temperature in the sample heating process is by infrared temperature sensor 2 monitoring, instrumentation control system will be per sample actual temperature and the power that changes microwave rf generator 5 of the relation between design temperature, not only can guarantee that the sample analysis process was fast but also can guarantee that sample is not burned.When the moisture in the sample during almost by evaporate to dryness, electronic analytical balance 7 passes to instrumentation control system with the information that unit interval weight change amount is close to zero, the power supply that control system will be cut off microwave rf generator 5 quits work by microwave, The whole analytical process is finished automatically and be need not artificial control, also reduce simultaneously personal error, guaranteed the repeatability of measurement result.
According to the quick moisture teller of microwave of the present utility model, compare with traditional moisture teller, the sample analysis process accurately, fast, homogeneous heating, efficiency of heating surface height, sample measurement is precision height, good reproducibility as a result, The whole analytical process has realized robotization.
