Oven drying method: it is that sample is heated under rated condition, and water evaporates is wherein fallen, and the quality of the remaining dry of weighing is compared with initial gross mass again, obtains moisture.The oven drying method principle is simple, and it is foundation that national standard or industry standard are often arranged, and can access the exact value of material moisture.The required Measuring Time of general oven drying method is all longer.
NEUTRON METHOD: the method that this method adopts moderation of neutrons method and fast neutron to penetrate more, what its was measured is the content of protium in the material, so it is bigger to be subjected in the material organic influence.And radioactive source meeting radiation neutron, so need to consider the radiation protection problem of instrument.
Capacitance method: this method is measured the conductivity of material, obtains the moisture of material.This method is subjected to the material self character easily, raw meal particle size, influences such as solid accumulation density.
Infrared reflection method: according under the condition of some wavelength, greater than its all band, infrared reflection method can only be measured the moisture on shallow surface to water to the absorption of infrared light.
Microwave method: divide transmission beam method, reflectometry resonant cavity method several.By measuring the effect of material,, try to achieve material moisture as reflection, decay, phase shift or resonance etc. to microwave.Existing microwave method often supposes that solid accumulation density remains unchanged substantially, in case therefore solid accumulation density changes, can directly influence the moisture measurement precision.
Summary of the invention
The purpose of this utility model is to be subjected to the solid accumulation variable density to influence bigger shortcoming at existing microwave transmission method, in conjunction with weighing technology, provides a kind of accurately quick, the quick device for measuring moisture that not influenced by the bulk density of material own.
The utility model is that a kind of microwave is measured the device of bulk solid sample moisture fast in conjunction with weighing, and this device partly is made up of microwave source (6), microwave emitting antenna (1), microwave antenna (2), Microwave Net (5), electronic signal process circuit (7), LOAD CELLS (4), bearing platform (3), cabinet and computer processor etc.Connecting between concrete parts is that microwave source (6) connects Microwave Net (5), and Microwave Net (5) connects microwave emitting antenna (1), and microwave antenna (2) connects Microwave Net (5); Microwave Net (5) and electronic signal process circuit (7) are in a shielding box, and electronic signal process circuit (7) has an interface to use for connecting power supply, and another interface is connected with the computer processor serial ports; LOAD CELLS (4) is connected with bearing platform (3).Wherein, two aerial position alignment; Microwave source (6), Microwave Net (5), electronic signal process circuit (7) and LOAD CELLS (4) are at the cabinet rear portion; Bearing platform is between antenna.
Than described existing measuring method, microwave method has following advantage:
(1) is not subjected to the influence of solid accumulation density;
(2) this apparatus measures time weak point can instantaneously be finished behind the button;
(3) this instrument adopts non-contact measurement, and failure rate is low, and reliable operation is harmless to sample, and is harmless to human body;
(4) this instrument adopts transmission-type to measure, and can take more sample, need not special sample preparation, reduced to gather and process the sample error.

Embodiment
Below in conjunction with description of drawings the utility model.
Fig. 1 the utility model measurement device synoptic diagram.Microwave instrument for quick measuring device partly is made up of microwave source (6), microwave emitting antenna (1), microwave antenna (2), Microwave Net (5), electronic signal process circuit (7), LOAD CELLS (4), bearing platform (3), cabinet and computer processor etc.Connecting between concrete parts is that microwave source (6) connects Microwave Net (5), and Microwave Net (5) connects microwave emitting antenna (1), and microwave antenna (2) connects Microwave Net (5); Microwave Net (5) and electronic signal process circuit (7) are in a shielding box, and electronic signal process circuit (7) has an interface to use for connecting power supply, and another interface is connected with the computer processor serial ports; LOAD CELLS (4) is connected with bearing platform (3).Wherein, two aerial position alignment; Microwave source (6), Microwave Net (5), electronic signal process circuit (7) and LOAD CELLS (4) are at the cabinet rear portion; Bearing platform is between antenna.
All signals are one way propagation, for guaranteeing the one way propagation of microwave signal, all add isolation at interface, the transmission course of signal: microwave signal is sent from microwave source (6), one the tunnel enters microwave emitting antenna (1) after process Microwave Net (5) power division, one the tunnel enters the inside of Microwave Net, the microwave that enters emitting antenna (1) through material is laggard go into microwave receiving antenna (2) after, enter Microwave Net (5) and before another road microwave signal again and together participate in the measurement that microwave attenuation and microwave phase move; The inner electric signal of Microwave Net (5) enters electronic signal process circuit (7), and is final to the decay of microwave and the information of phase shifts, and data are sent in the computer processor; The weight signal of material is obtained by LOAD CELLS (4), sends in the computer processor.
In the bucket of dress sample, adorn quantity of sample earlier when using, be pushed into the position that to measure.Fig. 2 measures the moisture process flow diagram for the utility model.Measure the quality of coal by LOAD CELLS, microstrip circuit and electronic signal process circuit collect through the decay of the microwave of coal and the information of phase shifts.Because the phase shifts of microwave is the cycle with 360 °, so the phase shifts that shows may be the phase place behind several integer circles, so according to before some decision conditions, decay and phase shifts are joined together, and judge the phase place of reality.After judging actual phase, according to the curve of demarcating before, bond quality information obtains the result of coal moisture.Read sample moisture result from computing machine then.
