In the utility model, because the UV digestion lamp is positioned outside the digestion pool, the size of the whole digestion device can be greatly reduced, at the same time, the industrial production difficulty of the digestion device can be reduced, the consumption of chemical reagent can be simultaneously reduced, and the detection time can be shortened. Because of the adoption of the temperature control circuit, the use safety can be improved.
Description
Technical field
The utility model relates to a kind of digestion instrument, particularly a kind of optical detection UV digestion instrument that is applicable to the controllable temperature protection of different analytical instrument in the technical analysis field.
Background technology
In daily life and industrial circle; automatic temp controller is very common: home-use electric cooker forces outage to protect control to reach hardware temperatures after utilizing and disconnecting absorption cast iron after (about 100 ℃) magnetic field of magnets dies down under the high temperature; it is to use this characteristic that shortcoming is in higher temperature control field; in the general automatic temperature-adjusting control system; be to utilize the software sampling temperature; carrying out temperature auto control then, its system generally comprises hardware structure, is controlled by software implementation.Its shortcoming is, if any one link of software or temperature sampling or the like breaks down, will cause by the temperature control unit temp out of controlly, causes by temperature control device part or permanent damages if find untimely meeting, causes bigger loss.Other temperature protective device cost that is used for the engineering field is bigger, moves and safeguard all inconveniences etc.
Common UV digestion instrument is that UV is cleared up the lamp digestion pool inside of packing into, causes the digestion pool volume bigger, and required chemical reagent is more, may cause secondary pollution.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, a kind of optical detection UV digestion instrument that is applicable to different analytical instrument in the technical analysis field is provided.
Technical scheme: in order to realize above purpose, a kind of optical detection UV digestion instrument that can temperature control of the present invention, comprising: digestion pool, resistive heater, hardware controls temperature sampling probe, UV clear up lamp, reflective mirror and circuit board; Resistive heater is wrapped on the digestion pool, and digestion pool is fixed in the reflective mirror; Described UV clears up the outside that lamp is positioned at digestion pool, and is fixed in the groove in the reflective mirror outside.Described circuit board is provided with a temperature control holding circuit, and this temperature control holding circuit links to each other with hardware controls temperature sampling probe, resistive heater respectively.
Among the present invention, UV clears up lamp and is in the digestion pool outside; Rather than be fixed in the inside of digestion pool, and directing energy radially in the digestion pool by reflective mirror, reach the purpose cleared up by absorbing the UV energy night in the digestion pool; The volume of whole digestion instrument has been dwindled in such design greatly, has reduced the commercial production difficulty of digestion instrument simultaneously, has reduced the consumption of chemical reagent simultaneously, has shortened detection time.
Also be provided with hardware controls temperature sampling probe among the present invention; the signal that this hardware controls temperature sampling probe sends and between the control system generation does not concern; temperature signal penetrates in the temperature control holding circuit that is attached thereto; the temperature control holding circuit is analyzed the temperature signal of receiving; as unusually; to force to disconnect the power supply of resistive heater, resistive heater will no longer be worked.
As preferred version of the present invention, described circuit board is provided with control system, and control system is provided with the temperature control signals input end; Be provided with a cover hysteresis comparator in the described temperature control holding circuit, postpone more intense input end and link to each other with hardware controls temperature sampling probe, output terminal links to each other with temperature control signals input end in the control system by triode; Described temperature control signals input end links to each other with resistive heater.
Because the temperature signal of hardware controls temperature sampling probe collection compares to determine temperature by hysteresis comparator and whether crosses the high temperature critical value, too high as temperature, hysteresis comparator output high level, the temperature control signals end is a low level, the energy supply dump of resistive heater, resistive heater is no longer worked, and has guaranteed the security of digestion instrument, has avoided digestion instrument to be damaged.
In order further to improve the security of digestion instrument, the output terminal of hysteresis comparator described in the present invention links to each other with the reset terminal of control system; When the output terminal of hysteresis comparator was exported high level, the control system reset terminal that links to each other with hysteresis comparator was a high level, and control system is forced to reset, and has realized automatically reseting of control system.
Beneficial effect: a kind of optical detection UV digestion instrument that can temperature control provided by the invention compared with prior art has the following advantages:
1) a kind of optical detection UV digestion instrument that can temperature control of the present invention, because UV clears up lamp and is positioned at the digestion pool outside, has dwindled the volume of whole digestion instrument greatly, has reduced the commercial production difficulty of digestion instrument simultaneously, reduce the consumption of chemical reagent simultaneously, shortened detection time;
2) a kind of optical detection UV digestion instrument that can temperature control of the present invention; owing to adopted the hardware controls temperature sampling probe that does not have direct relation with control system; and be provided with the temperature control holding circuit; avoided causing situation out of control, improved security of the present invention because of control system breaks down.
