It is to recall one of maximum project at present in the world at toy that the toy heavy metal lead element that comprises painting layer etc. exceeds standard.Import and export toy and all need to carry out the test of element total amount.The standard detecting method of toy total metals test at present generally adopts the wet method digestion device of electric boiling plate to clear up, but the glass container that wet method is cleared up need be through clearing up and shifting two steps of constant volume, the trouble that operates very, centre can cause sample loss and constant volume inaccurate.
Summary of the invention
Key in technical field herein and describe paragraph.At the shortcoming of prior art, it is a kind of easy to operate that the purpose of this utility model is to provide, and constant volume is accurate, can not cause the toy heavy metal detection of sample loss once to clear up volume fixing device and detection method thereof.
To achieve these goals, the technical solution of the utility model is, a kind of toy heavy metal detects once clears up volume fixing device, comprise temperature control heating device and clear up the constant volume device, the described constant volume device of clearing up comprises and clears up constant volume bottle and bottle stopper, the described constant volume bottle of clearing up is provided with the constant volume scale, and described constant volume scale is provided with multiple different constant volume scale mark; The described constant volume bottle of clearing up is up-narrow and down-wide long-neck ampuliform, comprises the long-neck part on top and the bottle of bottom, and described long-neck partly highly is at least 50% of bottle height, can guarantee that the toy heavy metal tests desired 60% condensing reflux ratio.
Further, in order to make heating-up temperature even, the temperature control deviation is little, precision is high, and described temperature control heating device comprises the control circuit of heating element, the Heat Conduction Material that is connected with heating element, sensor and temperature control heating device, described sensor respectively with clear up the constant volume device and be connected with control circuit.
Further, in order accurately to control the temperature that each clears up the constant volume bottle rapidly, described control circuit comprises and is used for carrying out the PID adjusting feedback control system of quick control to clearing up constant volume bottle temperature.
Further, the fan-shaped distribution of described heating element to clearing up the part fixed point heating of the concrete location of constant volume bottle, realizes that heating-up temperature is even.
Further, the described constant volume bottle of clearing up is a hard pyroceram forming materials.
Further, the described constant volume bottle of clearing up is gone to the bottom and is contacted with sensor cover.
Further, describedly clear up constant volume bottle bottleneck and the bottle stopper contact position is the frosted moulding, prevent leakage.
Further, the described bottleneck of clearing up the constant volume bottle is the standard bore, can be common to the glassware of all bottles and other standard bores.
Compared with prior art, the utlity model has following advantage: the utility model toy heavy metal detects once clears up the mode that volume fixing device does not need to clear up by traditional electric boiling plate back transfer constant volume, can adopt a set of equipment, directly once finish and clear up and two kinds of steps of constant volume, reduce the loss of sample and the error of constant volume, accelerated testing efficient greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, the utility model toy heavy metal detects once clears up volume fixing device, comprise temperature control heating device 1 and clear up constant volume device 2, the control circuit 5 of Heat Conduction Material 3, sensor 4 and temperature control heating device that temperature control heating device 1 comprises heating element, be connected with heating element, sensor 4 respectively with clear up constant volume device 2 and be connected with control circuit 5; Control circuit 5 comprises and is used for carrying out the PID adjusting feedback control system of quick control to clearing up constant volume device 2 temperature, the fan-shaped distribution of heating element, temperature control heating device 1 can accurately be controlled each temperature of clearing up bottle rapidly, makes heating-up temperature even, and the temperature control deviation is little, precision is high; Clear up constant volume device 2 and comprise that the standard mouth clears up constant volume bottle 21 and standard plug 22, state and clear up constant volume bottle 21 and be provided with constant volume scale 23; Clear up constant volume bottle 21 and be up-narrow and down-wide long-neck ampuliform, comprise the long-neck part on top and the bottle of bottom, described long-neck part highly is at least 50% of bottle height, and this structure, shape, size can guarantee that the toy heavy metal tests desired 60% condensing reflux ratio.Clear up constant volume bottle 21 bottom surfaces and contact, can guarantee the even of temperature with sensor 4 large tracts of land.Clear up the constant volume bottle and adopt special hard glass material, be suitable for the heating operation of the digestion condition of toy test request, this structure and material of clearing up constant volume bottle 21 guarantees that its content volume after clearing up operation changes less than 0.5%.
Clear up the constant volume scale 23 that constant volume bottle 21 is provided with a plurality of volumes of special adaptation toy heavy metal detection, can satisfy the demand of different constant volumes.Clear up constant volume bottle 21 bottlenecks and bottle stopper 22 contact positions for preventing the frosted moulding of leakage, prevent leakage.The bottleneck of clearing up constant volume bottle 21 is the standard bore, so can be common to the glassware of bottle and other standard bores.
The work engineering of the utility model device is as follows:
Clear up bottle 21 with quantitatively putting into constant volume after the toy heavy metal test request pulverizing by toy input target state (as European Union, the U.S., Canada etc.) such as toy paint sample, on heating the device of program, control heats, behind the chemical solvents such as adding nitric acid, finish by the test request of toy input target state and all to clear up program, obtain digestion solution; This is cleared up constant volume bottle 21 and can finish and clear up and whole digestion process such as a certain proportion of condensing reflux, makes testing sample catapepsis dissolving.Then, this is cleared up constant volume bottle 21 and takes off the back cooling from temperature control heating arrangement 1, directly adopts the solvent medium constant volume to clearing up constant volume bottle assigned scale 23.Last filtering supernatant is carried out check and analysis, finishes whole testing processes.The utility model is finished in same bottle and is cleared up and constant volume, and heating-up temperature evenly, the temperature control deviation is little, precision is high.Clear up constant volume bottle 21 and can realize a certain proportion of condensing reflux effect.
Above embodiment only is used to illustrate the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment; those of ordinary skill in the field are to be understood that; still can make amendment or the part technical characterictic is equal to replacement embodiment of the present utility model; and not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
