Description
Technical field
The utility model belongs to cotton hydrogenous measuring gage device field, is specifically related to a kind of resistance-type cotton moisture measurement device that applies on the cotton press.
Background technology
Cotton all contains moisture content under normal conditions, it contains the performance such as the physics that how much affects cotton fiber, chemistry, Mechanics of Machinery of moisture content, particularly affect the weight of cotton fiber, and cotton is a kind of big transaction commodity of combining, its turnover is by weight calculation, therefore, what are very big to the influence of turnover for water content.The standard water content of national regulation cotton, promptly official regain is 8.5%, and cotton to be a kind of moisture absorption loose very strong commodity of moisture performance.In order to embody rule of fair trade, the water content (regain) that accurately detects cotton is vital.
In the past, the detection method of domestic employing is a sample detecting, specific practice is: cotton is detected in batches, general hundreds of bag is one batch, in the cotton ginning process of every batch of cotton, from the cotton passage every once sampling half an hour, taking this sample to laboratory then goes to detect, draw the water content of each sample, obtain a mean value again, this value is promptly as the water content of this batch cotton (being hundreds of bag cotton).When rechecking, the methods of sampling by national regulation is: per 10 bags are taken out a bag in this batch cotton, each sampling bale of cotton extracts about 100 grams of regain check sample, again these samples are brought to and measure water content in the laboratory, and obtain a mean value, this value is the water content of this batch cotton (being hundreds of bag cotton).Clearly this sample detecting and sampling are rechecked and all had deficiency: 1, the cotton trading units is a bag, detect the cotton water content and also should be accurate to every bag, and the data that said method draws are all for a collection of cotton, and these data are very inapt to concrete a certain bag; 2, cotton very easily moisture absorption loose wetly, in the sampling Detection process, its water content is easy to morph, and causes the error increasing of last detected value and actual value; 3, must repeatedly sample, complex procedures trouble.Therefore, above-mentioned detection is more backward.
For further in line with international standards, the National Cotton standard is reformed, and proposes water content of each bag cotton is detected, and will finish weighing and the measurement of water content of cotton simultaneously when cotton is packed.Therefore, this has proposed new demand just for the moisture content pick-up unit of cotton.And existing cotton hydrogenous measuring gage device all applies in the laboratory, only acts on sample, can't combine with cotton press, can not satisfy above-mentioned requirements.
For this reason, the utility model has been developed a kind of moisture measurement device that applies on the cotton press just at above-mentioned requirements, and this device accurately detects the contained moisture content of the bale of cotton with electric-resistivity method when cotton is packed.

4, in the technique scheme, for nude enamelled packing object, described electrode pair can be arranged on the last inwall or following inwall of the compressing and forming cavity in the baling press hopper, and the surface of electrode can be concordant with last inwall or following inwall, also can protrude from inwall or following inwall; If inwall or be provided with the sampling cutting knife on the inwall down on the compressing and forming cavity in the baling press hopper, blade that so should the annular cutting knife promptly can be used as an electrode, and is provided with another electrode at the middle part of this annular cutting knife, is provided with insulator between two electrodes.
5, in the technique scheme, described electrode can be arbitrary shape, cylindrical, conical, cube, strip, and preferred version is: an electrode is tabular in the electrode pair, another electrode is cylindrical and the outer wrapping insulator is embedded in the plate electrode.
6, in the technique scheme, described electrode pair quantity is not limit, and can on each inwall of compressing and forming cavity a plurality of electrode pairs be set, and can draw bale of cotton water content everywhere and average, makes measurement more accurate.
7, in the technique scheme, described temperature sensor can adopt semiconductor temperature sensor, metal oxide temperature sensor, platinum temperature sensor etc.
8, in the technique scheme, described metering circuit and regain calibration value, temperature modified value can adopt prior art, such as, Chinese patent is disclosed on October 2nd, 2002, name is called " one grow cotton moisture content electrical measuring method and electroprobe ", and application number is 01108102.3 application for a patent for invention.
The utility model principle of work is: when baling press is compressed into the bale of cotton with cotton, the density of cotton reaches definite value, cotton can be close on the electrode pair simultaneously, at this moment can detect two interelectrode resistance values by circuit, the temperature of the simultaneous temperature sensor bale of cotton, draw a signal, add the temperature modified value according to the relation of resistance and water content then, can draw the water content of cotton.On each inwall of compressing and forming cavity, a plurality of electrode pairs are set, can draw bale of cotton water content everywhere, and obtain the water content (regain) of mean value as this bale of cotton.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because electrode pair of the present utility model is arranged on the inwall of the compressing and forming cavity in the baling press hopper, and cotton has been compressed into the bale of cotton during detection, and the density of cotton is basic fixed, cotton contacts closely with interelectrode, easily realizes high-acruracy survey;
