Description
Technical field
The present invention relates to calcium carbide gas forming amount determination techniques field, specially a kind of automatic assay device of calcium carbide gas forming amount.
Background technique
Currently, being by lab technician by GB 10665-2004 content-using device in the measurement work of daily calcium carbide gas forming amount
Manual operation carries out.
It is to open valve manually by lab technician 2L tap water is added in generator first, removes counterweight and press bell jar and answer
Position is to zero point；Then weighed calcium carbide sample 50g is put into sample room rapidly, closes lid immediately and screwed, close exhaust
Valve；Counterweight is placed, while rotating turnover panel handle, it is artificial to read scale numerical value, note after sample is fully immersed in water about 10min
Atmospheric pressure and mercurial thermometer scale are recorded, then result is calculated with formula and retains；After the completion of measurement, sample addition zone is opened manually
Blowdown valve, manual cleaning waste water.
Present mode shortcoming is mainly manifested in the following: 1. water supply ways: water supply way is artificial in generator
Control valve operation, the water of standard requirements not can guarantee accuracy.2. bell jar acts: in bell jar uphill process, two sides guiding
Wheel inevitably will appear card resistance phenomenon caused by discontinuity with push plate cylinder, and at this moment needing lab technician to pat bell jar just can be real
It is now steady to rise.When bell jar resets, since internal compressed air acts on, cannot rely on oneself zero, need Manual press to zero-bit, and
Next step movement can be just carried out after keeping pressure balance.And bell jar firmly excessive may also result in saturated salt solution when pushing
It overflows.3. large labor intensity: sample-adding front and back is required to lab technician and uncaps rapidly, close lid, controlled valve, pick and place counterweight, building ring
More, distance is saved, working efficiency is low.30-40 sample is about acquired daily, and each sample need to be chemically examined three times, and chemical examination is time-consuming every time
10min.And after the completion of each sample chemical examination, it is also necessary to remaining ferrosilicon waste residue after manual cleaning waste water and calcium carbide reaction, labor
Fatigue resistance is big.4. data acquisition process: lab technician is easy doping artificial subjective factor, nothing when reading scale value and calculated result
The accuracy of method guarantee final result.5. cheating or maloperation: existing chemical examination mode whole process is artificial to be participated in, and is difficult effectively to prevent a
Other cheating or maloperation can not carry out effective calcium carbide sample information privacy management.
