Description
Technical field
This utility model is specifically related to a kind of distillation cup anti-dry burning device for azotometer.
Background technology
The measure of protein content is respectively provided with important application in fields such as food processing, agricultural production, feedstuff, fertilizer.
In azotometer, distilling apparatus are important parts, the evaporation of moisture necessarily moisturizing in still-process, such as hydropenia, moisturizing not in time
And continue heating and cause machine dry combustion method, can make the machine breakdown, or even the anti-dry burning device of the present azotometer of fire be when serious：1.
By Level Detection, after liquid level declines, automatic water supplement, the problem for existing：When dry combustion method will be produced after detection probe failure；2. exist
Temperature sensor is put on the basis of Level Detection, cup temperature is distilled after producing dry combustion method and is steeply risen so that sensor produces signal and gives
Single-chip microcomputer, existing problems：Due to starting hydropenia, temperature hardly rises, and when dry combustion method is produced, temperature steeply rises, and temperature is passed
Sensor be usually double-reed have delayed to temperature, if the time delay of sensor is long, will substantial dry combustion method and make instrument
It is impaired.
The content of the invention
The purpose of this utility model be to provide one kind on the basis of Level Detection, using distillation cup special construction and do not have
The distillation cup anti-dry burning device for azotometer of the purpose of anti-dry is reached with temperature sensor.
This utility model is employed the following technical solutions：
For the distillation cup anti-dry burning device of azotometer, it is characterized in that, including liquid level bottle, distillation cup, liquid level bottle, distillation cup
Connected by constant pressure pipe, electric heating tube, temperature sensor are provided with distillation cup, are provided with liquid level detection device in liquid level bottle.
Wherein, the liquid level detection device includes the probe level lower limit dress that end is gradually increased with liquid level bottle distance from bottom
Put, probe datum level device, probe level upper limit device.
Wherein, constant pressure pipe is two, is respectively communicated with liquid level bottle, the bottom of distillation cup and liquid level bottle, the top of distillation cup.
Wherein, the distillation cup is built with distilled water.
Wherein, distill cup top and be provided with steam pipe.
The technology is invented on the basis of Level Detection, typically when a supplementary water probably can distill the 10-40 seconds, then
Moisturizing again, so circulates.After Level Detection failure, single-chip microcomputer just can not receive liquid level signal, just distill always, until dry combustion method.
This device is, when moisturizing interval was more than 60 seconds, to be considered as liquid level failure, and single-chip microcomputer quits work, and reports to the police.Avoid dry combustion method
Produce.Design due to distilling cup, distillation hydropenia is in 150 seconds all without the substantial hydropenia of generation.This addresses the problem temperature
Degree sensor just must can be reacted to after substantial generation dry combustion method, consequently, it is possible to the damage to instrument.
The present application technology of distillation cup anti-dry is simple：Temperature probe, air in detection cup, as long as electricity adds are put in distillation cup
Heat pipe does not completely disengage from liquid level, and the temperature of air is not changed in.After electric heating tube departs from, what air themperature will be drastically carries
Height, and temperature sensor is using double-reed, the also hysteresis quality of discreteness and time, it is possible to after detecting dry combustion method, temperature
Very high, instrument has been damaged, and may only be reduction of impaired degree.
The device seeks to Non-Destructive Testing, and when substantial dry combustion method is not reaching to, instrument has been reported to the police and stopped distillation.Really
Protect instrument to be not damaged.
After instrument start, if liquid level bottle distillation water level liquid level is less than probe level upper limit device, in certain hour, liquid level
Not up to probe level upper limit device, instrument send alarm signal, and needs are checked.
Generally within the 10-40 seconds (excessive moisturizing can be adjusted, but excessive moisturizing will make in running
Distillation significantly stops and affects detection), liquid level is less than detection sensor probe level upper limit device, can send moisturizing request,
Single-chip microcomputer is connected to the request and will send moisturizing order so that liquid level reaches normal level, iterative cycles.When Level Detection fails
When, single-chip microcomputer can not receive the request of moisturizing, will distill always, this device be exactly single-chip microcomputer it is continuous 60 seconds (this time according to
Specific condition suitably determines) moisturizing request is not received, it is considered as Level Detection failure and stops distilling and reporting to the police.At this moment liquid
Without departing from electric heating tube, instrument is not damaged for position.
The beneficial effects of the utility model are：Before no substantial dry combustion method, Level Detection failure is had been detected by, and
Report to the police and stop distillation, it is ensured that instrument is injury-free.And without temperature sensor and temperature sensing circuit so that under instrument cost
Drop.
