Abstract
The utility model relates to a water content measuring instrument, which measures residues thereof via evaporation. The utility model is characterized in that by the designs of a rotation control part and a longitudinal shift control part, a general microwave oven is organically combined with an electronic balance and can automatically weigh multiple test samples at the same time; then data are input to a computer for printing a result. Compared with a domestic water content measuring instrument, the utility model has the advantages of short measuring time, low cost, high automatization, etc. and the utility model can be connected with the computer for control and can be widely used for using in the coal industry, the cement industry, the ceramics industry, the tobacco industry; the multiple samples can be sent at the same time.
Description
The utility model relates to a kind of moisture determination instrument by evaporation and its residue of weighing.
Present domestic moisture content determinator mainly is to use electronic balance, adds the KETT that an infared dryer is formed in addition, can only make a sample at every turn.Have only West Germany Du meaning fort Bradley originally to reach the KETT (RAPID MOISTVRE TES TER H-A-G " E ") that (BRABENDER OHGDVISBVRG) company produces abroad, by (resistance wire heating) baking oven, the poidometer that electronic balance and stepper motor etc. are formed, can make 10 samples at every turn, but its drying time is long, stepper motor and power supply cost height.
At above problem, it is short to the purpose of this invention is to provide a kind of drying time, and the complete machine cost is low, can carry out the moisture determination instrument that a plurality of samples are measured automatically again simultaneously.
In order to achieve the above object, the utility model has been taked following design: a kind of moisture determination instrument comprises: the oven dry part, and the Spin Control part vertically moves control section and electronic balance, it is characterized in that:
Oven dry part: adopt common microwave stove; on original glass pallet, leave weighing hole less than the weighing disk top diameter; weighing disk places on the weighing hole; in described micro-wave oven bottom; open a through hole and in described through hole, be provided with metal protection protector; place this weighing bar one end of weighing bar in this protective sleeve and aim at one of them weighing disk, the other end connects with the electronic balance weighing position
The Spin Control part: motor driven gear, this gear are fixed on the turning axle that joins together with tray supporter, and a side of described gear is installed an optical disc and optoelectronic switch,
Vertically move control section: the driven by motor cam, a side of this cam is installed an optical disc and optoelectronic switch, and described cam outer rim contacts with described turning axle bottom.
In order to make weighing location more accurately and reliably, weighing disk adopts the reverse frustoconic shape, and its base diameter is less than the diameter of described weighing hole, and weighing disk can be seated in the weighing hole.
The utility model is owing to adopt the mode of microwave heating, can greatly shorten drying time compares with the moisture determination instrument of West Germany, when sending into a plurality of samples and measure, drying time shortened to 15 minutes by original 120 minutes, again because the automatic controls that adopts optical disc and optoelectronic switch etc. to form, make and make and keep in repair very convenient, greatly reduce cost simultaneously.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Accompanying drawing 1 is a front view of the present utility model.
Accompanying drawing 2 is right side cross-sectional view of Fig. 1.
Accompanying drawing 3 is position views of the weighing hole of opening on the glass pallet
Accompanying drawing 4 is Spin Control part motor driven gear synoptic diagram.
As shown in Figure 1, the oven dry part is to adopt common microwave stove 1, and original glass pallet 16 in the micro-wave oven 1 is bored six weighing hole 19(as shown in Figure 3), the diameter of weighing hole 19 is less than weighing disk 17 top diameters.General weighing disk is columniform, puts a weighing disk 17(on each weighing hole 19 as shown in Figure 2).A through hole 15 is left in micro-wave oven 1 bottom put a metal protection protector 14 in through hole 15, put a weighing bar 13 in protective sleeve 14, weighing bar 13 1 ends are aimed at one of them weighing disk 17, and the other end connects with the position of weighing of electronic balance 11.Spin Control partly is the turning axle 3 that is fixedly connected in micro-wave oven 1 original tray supporter 2 bottoms, gear 6 is housed on the turning axle 3, one side of gear 6 is equipped with an optical disc 4 and optoelectronic switch 5, with turning axle 3 cog 6 the engagement another gears 6 connect with motor 20.Vertically moving control section, is that cam 7 is connected with motor 8, and a side of cam 7 is installed an optical disc 9 and optoelectronic switch 10, and cam 7 outer rims contact with the bottom of the turning axle 3 of Spin Control part.
In the above-described embodiments, the quantity of the weighing hole of opening 19 can increase or reduce as required on the glass pallet 16.The shape of weighing disk 17 also can adopt the weighing disk 18(of reverse frustoconic shape shown in Fig. 2 two-dot chain line), its base diameter is less than the diameter of weighing hole 19, weighing disk 18 can be seated in the weighing hole 19, in rotation, can make the weighing disk location more like this.
In the time of operation, the motor of Spin Control part is by gear drive, drive the tray supporter rotation that joins together with turning axle, the glass pallet rotates under the cooperation of original keyway with tray supporter, weighing disk on the glass pallet is aimed at the weighing bar that connects with electronic balance successively, made to rotatablely move by optoelectronic switch by the breach on the optical disc to stop, the time length that it stops to be determined by timing relay.Rotatablely move stop in, start with the control section that vertically moves of its interlocking, motor is by the axially motion down of cam outer rim driven rotary, thereby driving the glass pallet moves down, the weighing disk quilt rises with the weighing lever bracket that the scales/electronic balance weighing position is linked together, show weighing data on the electronic balance, and it can be imported computer printout.After weighing finished, optical disc and optoelectronic switch in time stopped to vertically move motion again, and startup rotatablely moves, and carries out the measurement of next sample.
