Abstract
The utility model relates to an intelligent water content measurer by a drying method, belonging to an apparatus for measurement, composed of a drying baker, a microprocessor system, a weighing sensor, etc. The weighing sensor of a cantilever type is fixed outside the bottom part of the drying baker, a weighing bracket which passes through the bottom of the drying baker is extended into the drying baker, and infrared rays sent out by an infrared ray lamp which is arranged at the top part of the drying baker are directly projected onto a sample tray. Microwaves can also be used as a heat source for drying. The utility model can measure water contents by the drying method; the utility model has the advantages that the operation is simple, human errors and environmental impacts can be eliminated, the measuring accuracy can be enhanced, and testing periods can be shortened. The utility model is suitable for measuring water contents in grain, and is suitable for measuring water contents by the drying method in other fields. The utility model can be used as a reference apparatus for correcting other apparatus which are formed according to the principle of non-drying methods.
Description
Oven drying method intelligence moisture teller belongs to detecting instrument.
Grain moisture content is measured and is adopted oven drying method at present.The laboratory is equipped with drying baker, and day equality equipment by full-time lab technician's operation, is weighed and calculated through repeatedly repeating, and can obtain testing result.Operation is loaded down with trivial details, and sense cycle is long, easily produces personal error, is subject to the influence of ambient temperature humidity.
The objective of the invention is to, a kind of instrument of the mensuration grain moisture content that is made of oven drying method is provided, simplify the operation of determination of moisture, get rid of the influence of personal error and ambient temperature and humidity, shorten sense cycle.
Oven drying method intelligence moisture teller adopts box-shaped enclosure, and right upper portion is a microprocessor system, and keyboard and display are arranged on the panel, and lower right side is a power supply, and switch and pilot lamp are arranged on the panel.Left side 2/3 is the drying baker of sheet metal welding in the casing, bottom the drying baker, be fixed at the bottom of the shell by leg on.Drying baker bottom outside screw retention cantilevered LOAD CELLS, use the electric connection of umbilical cable between LOAD CELLS and the microprocessor system, the LOAD CELLS load side is the check weighing support fixedly, the check weighing support passes at the bottom of the drying baker and appropriate gap is arranged, the check weighing support stretches into and is about 1/3 of drying baker height in the drying baker, relative up and down with the infrared ray bulb at drying baker top, sample tray is placed on the check weighing support.Infrared ray bulb is fixed on the drying baker top outer, and circular hole is opened at the drying baker top, and diameter and infrared ray bulb are suitable, adjusts infrared ray bulb and makes infrared ray directly invest sample tray.Drying baker has with gemel door in the panel side.The drying baker sidewall has vent port.Pyrotoxin can adopt microwave or infrared ray.
The present invention adopts oven drying method, because the participation of LOAD CELLS and microprocessor system is arranged, makes operation very simple, and the common laborer can finish.Dry and weigh and carry out,, get rid of the influence of personal error and environment temperature and humidity, improved accuracy of measurement, shortened sense cycle by microprocessor analysis computing and judgement in the same time of same environment.The instrument volume is little, and is not tight to environmental requirement.
Oven drying method intelligence moisture teller is applicable to measuring grain moisture content, can be equipped with oven dry workshop workman and use the self-examination dries quantity.Can detect grain moisture content for rural area grain purchasing station point, and other adopt oven drying method to measure the field of moisture.Can be used as reference instrument and proofread the instrument that other non-oven drying method principles constitute.
Figure of description is oven drying method intelligence moisture teller general structure and drying baker internal structure synoptic diagram.
Embodiments of the invention: oven drying method intelligence moisture teller is the casing of 40cm * 30cm * 30cm, goes to the bottom on the shell 7, both sides and rear panel, front panel left side 2/3 welded by the sheet steel panel beating.Right side of face 1/3 is the plastic instrument panel before the shell.Right upper portion is microprocessor system (5), and the single-chip microcomputer model is 8032, touches keyboard and light-emitting diode display on the panel, and lower right side is 220v AC power (6), and switch and pilot lamp are arranged on the panel.The drying baker (2) that weld for sheet metal in casing left side, four jiaos of drying baker bottom outside are directly welded four band steel legs with the case dolly, and leg is screwed at the bottom of the shell.Drying baker bottom outside screw retention cantilevered LOAD CELLS (1), the range of LOAD CELLS are 300 grams, and precision is 0.0002.The LOAD CELLS load side is the check weighing support fixedly, the check weighing support passes at the bottom of the drying baker and appropriate gap is arranged, the check weighing support stretches into and is about 1/3 of drying baker height in the drying baker, and is relative up and down with the infrared ray bulb (4) at drying baker top, and sample tray (3) is placed on the check weighing support.Infrared ray bulb is fixed on the drying baker top outer, and circular hole is opened at the drying baker top, and diameter and infrared ray bulb are suitable, adjusts infrared ray bulb and makes infrared ray directly invest sample tray.The infrared ray bulb specification is 220v500w.Drying baker has with gemel door in the panel side.The drying baker sidewall has vent port.
The course of work of oven drying method intelligence moisture teller: LOAD CELLS and microprocessor system constitute the high-precision electronic scale, empty pallet is put on the check weighing support, press the reset key on the panel, display shows " 0 ", take out about 20 grams of sample that sample tray is packed into and pulverized, be put on the check weighing support, microprocessor system weighs up example weight G automatically
0And store, along with thermal source constantly sends energy, pass to sample, make moisture evaporation, example weight constantly descends.Electronic scales Td measuring samples at set intervals once obtains the new weight G of sample
1, G
2... Gn whenever records a new weight and compares with previous measured value, works as G
N+1During=Gn, interpret sample is dried, and this moment, microprocessor system calculated (G automatically
0-Gn)/G
0Be exactly sample moisture.Show measurement result by display.Wherein time interval Td can require to be provided with on panel according to accuracy of detection, and Td is big more, and measuring accuracy is high more, and required Measuring Time is long more.
Claims (1)
1 oven drying method intelligence moisture teller is by box-shaped enclosure, formation such as drying baker and microprocessor system, it is characterized in that: drying baker bottom outside screw retention cantilevered LOAD CELLS, use the electric connection of umbilical cable between LOAD CELLS and the microprocessor system, the LOAD CELLS load side is the check weighing support fixedly, the check weighing support passes the drying baker end stretch and goes in the drying baker, relative up and down with the infrared ray bulb at drying baker top, sample tray is placed on the check weighing support, infrared ray bulb is fixed on the drying baker top outer, circular hole is opened at the drying baker top, and infrared ray bulb sends infrared ray and directly invests sample tray, and the oven dry thermal source also can adopt microwave.
