Principle of work.When using the quick moisture teller of the utility model, three kinds of testing samples are put into three material discs 1 respectively, close the door of heating cavity 2, power-on 25, this instrument gets electric work.The software and instruction relevant portion that exists among the CPU U1 is carried out in the instruction that CPU U1 keys in from keyboard 23 by the user, controls and commands this instrument to finish the work of intelligent electromechanical integration fast measuring moisture.The moisture that now with the user instruction is mensuration and show sample 1 is that example illustrates it.1, the first weight W of working sample 1
Just: CPU U1 is by control interface 12 controls and command rotating bracket device 12e in the following manner, when closing in 3,4 o'clock, opens the normally opened contact of relay K 5, motor 5 and material disc 1 with in stop when changeing, material disc 1 with non-displacement damping locator meams be parked in pressure sensing bar 6 directly over; CPU U1 weighs jacking gear 12c in the following manner by control interface 12 controls and commander, normally opened contact 3,4 closures of relay K 3, cam mechanism 7 actions, driving pressure sensor bar 6 and LOAD CELLS 13b rise, and material disc 1 is held in the palm from rotating bracket device 12e; LOAD CELLS 13b takes by weighing the weight of sample 1, convert weight information to analog electrical signal, from its output terminal output, this signal amplifies through amplifier U5:A and U5:B high-gain and low noise, through electronic analog swtich U4 gating, and modulus converter A/D D1 analog to digital conversion, convert digital signal to, deliver to CPU U1, deposit the storage zone of the sample 1 first weight of EEPROM 20 in, as the first weight W of sample 1
JustThe jacking gear 12c that weighs descends, and material disc 1 is put back to rotating bracket device 12e.2, heat drying sample 1: the temperature in the temperature sensor 13a sensing heating cavity 2, convert temperature information to analog electrical signal, from its output terminal output, this signal is through electronic analog swtich U4 gating, modulus converter A/D D1 analog to digital conversion, convert digital signal to, deliver to CPU U1, CPU U1 judges that whether this digital signal is greater than 105, mean 105 ℃, when this digital signal less than 105 the time, CPU U1 is by control interface 12 controls and commander's infrared heater 12a, microwave applicator 12b, exhausting dehumidification system 12d and rotating bracket device 12e are in the following manner, relay K 1, K2, the normally opened contact 3 of K4 and K5,4 closures, open Infrared Heating fluorescent tube 120, microwave tube 121, exhausting hydrofuge fan 123,124 and motor 5, infrared heater 12a, microwave applicator 12b, exhausting dehumidification system 12d and rotating bracket device 12e work, heat up in the heating cavity 2, the moisture example of described mensuration and show sample 1 is in this situation, microwave applicator 12b makes sample 1 inner heat, the moisture that it is inner is arranged in its surface, the water evaporates that infrared heater 12a will depend on sample 1 surface becomes steam, exhausting dehumidification system 12d drains into the steam in the heating cavity 2 outside the heating cavity 2, dry hot-air from top to bottom, in time take away the moisture of discharging by microwave heating and Infrared Heating, rotating bracket device 12e rotates sample 1 in heating cavity 2, obtain uniform heating; When this digital signal is equal to or greater than 105, CPU U1 is by control interface 12 normally opened contact 3,4 disconnections, the disconnection, closed and closed of pilot relay K1, K2, K4 and K5 respectively, Infrared Heating fluorescent tube 120 and microwave tube 121 are closed, exhausting hydrofuge fan 123,124 and motor 5 work on, and realization exhausting dehumidification system 12d carries out the exhausting hydrofuge to heating cavity 2 and sample 1 is evenly heated under the situation of 105 ℃ of constant temperature.3, the last weight W of working sample 1
The end: whole instrument worked by above-mentioned 2 mode, every 20 seconds, CPUU1 started a samples weighing program, promptly is similar to above-mentioned 1 program, measure the last weight of a sample 1, the last weight that records is for the first time deposited the storage zone of the sample 1 last weight of EEPROM 20; CPU U1 is with the last weight and primary the comparing that record for the second time, and generally speaking, the former must be less than the latter, and CPU U1 deposits the former in EEPROM 20 in the mode that covers the latter, and the rest may be inferred by analogy; After 3～15 minutes, the moisture in the sample 1 is dried, and the end that promptly adjacent secondary records is equal in weight, and sample 1 enters the constant weight state, at this moment, is stored in the last weight W that the interior last weight of EEPROM20 is sample 1
The end, the EOP (end of program) of the last weight of working sample 1.4, the moisture of calculation sample 1: CPU U1 is according to first weight W
JustWith last weight W
The endThe moisture of calculation sample 1, the moisture of sample 1=(W
Just-W
The end)/W
Just* 100%; CPU U1 deposits The above results in the storage zone of sample 1 moisture of EEPROM20.5, the moisture of show sample 1: CPU U1 controls and commands infrared heater 12a, microwave applicator 12b, exhausting dehumidification system 12d and rotating bracket device 12e in the following manner: the normally opened contact 3,4 of K1, K2, K4 and K5 disconnects, and Infrared Heating fluorescent tube 120, microwave tube 121, exhausting hydrofuge fan 123,124 and rotating bracket device 12e do not work; CPU U1 takes out the moisture of sample 1 from EEPROM 20, deliver to light-emitting diode display 21, shows from it.So far, instrument has been finished the user with aptitude manner and has been keyed in the mensuration of instruction regulation and the task of show sample 1 moisture by keyboard 23, gets ready for measure next time.In like manner, instrument can also finish that the user keys in to give an order: measure and show sample 2 sample 3, sample 1 and sample 2, sample 1 and sample 3, sample 2 and sample 3, sample 1, the moisture of sample 2 and sample 3, the principle of these determinations of moisture and above-mentioned principle are similar, just seldom give unnecessary details here.In addition, instrument can also finish that the user keys in to give an order, as a moisture that records is transferred to printer through printer interface 19, come out by printer prints again; The moisture that records is transferred to host computer through standard serial mouth 22, by host computer data are done further information processing again.Because these are the technology that the insider is familiar with, just no longer repeat here.
Compare with background technology, the utlity model has following outstanding effect:
1. sample heat drying time weak point only needs 3～15 minutes;
2. sample must not pulverized, and microwave energy makes the sample interior heating, and the moisture in it is arranged in its surface;
3. measuring accuracy height, the utility model can be measured the fluid loss of sample in heating cavity, stopped sample and must take out the disadvantage that heating cavity carries out cold title behind 105 ℃ of freeze-day with constant temperature, because during cold title, sample can adsorb the moisture in the environment, causes measuring error;
4. sample still can be measured its moisture below 0 ℃ with the utility model.
