Abstract
The utility model provides a BOD microbial membrane sensor heating constant temperature equipment, includes heating member and thermostat, and characterized by heating member is cylindrical aluminium bar, and open on the surface has spiral half slot, and heating element and temperature measurement sensor are placed to inside, and the sampling tube is around in the half slot, and the thermostat is the constant temperature water bath that the bottom was equipped with heating member and thermoscope, is equipped with in the water bath and measures pond and microbial membrane sensor, measures the pond export and links to each other with the peristaltic pump. The utility model is used for carry out twice heating and heat preservation to the measured water appearance when the BOD is measured fast, can accurate control measurement temperature at 25 ℃ -30 ℃ within range, make the microorganism have good activity to the measurement accuracy of sensor has been guaranteed.
Description
Technical field
The utility model relates to a kind of experiment heating constant-temperature equipment, the heating constant-temperature equipment of detected water sample when measuring BOD in particular for the employing microbiological sensor.
Background technology
When adopting microbiological sensor that water sample is carried out the BOD measurement, microorganism has activity in certain temperature range, experimental results show that sensor has bigger response in the time of 25 ℃～35 ℃, and temperature is bigger to the influence of electrode, therefore generally will carry out heat tracing to detected water sample (comprising microbiological sensor).Insulation materials such as heating of many at present employing pipelines and wool felt are incubated, and its major defect is that heat time heating time is short, and non-uniform temperature is difficult to accurate temperature controlling, has the measured value fluctuation during experiment and reappears phenomenons such as poor, has a strong impact on measuring accuracy and stability.
The utility model content
The technical problems to be solved in the utility model provides that a kind of heat time heating time is abundant, and temperature is even, and temperature control is accurate, thereby effectively improves the BOD microbial membrane sensor heating constant-temperature equipment of measuring accuracy.
The technical solution of the utility model is: BOD microbial membrane sensor heating constant-temperature equipment, comprise calandria and thermostat, improvements are that described calandria is cylindrical aluminium bar, its surface has spiral half slot, inner porose, place heating element and temperature probe in the hole respectively, stopple coupon is in half slot, and described thermostat is the thermostatted water bathing pool that the bottom is provided with heating member and thermal detector.
In the such scheme, aluminium bar diameter 45～55mm, long 90～110mm; The heating element of placing in the aluminium bar is the heating wire of 50W; Place measuring cell and microbial membrane sensor in the thermostatted water bathing pool, the import of measuring cell with walk around aluminium bar spiral fluted stopple coupon and link to each other; The outlet of measuring cell links to each other with peristaltic pump.
In above scheme, adopt the method for twice heating and insulation that detected water sample is carried out heat tracing, whole measuring cell and microbiological sensor are carried out constant temperature, at first as calandria water sample is heated with aluminium bar, because the helical groove structure of aluminium bar, increased the length that stopple coupon contacts with aluminium bar, heat time heating time is long, secondly the aqueous sample stream that heated is heated once more and is incubated through the thermostatted water bathing pool, because the water in the sea water bath can be evenly distributed in around stopple coupon and the measuring cell, and temperature is even, the effect of temperature probe of aluminium bar and sea water bath bottom in addition, thus can accurate temperature controlling, thereby guaranteed biology sensor by constant on design temperature, keep 25 ℃～30 ℃, also just guaranteed measuring accuracy.
Description of drawings
Accompanying drawing is the utility model structure, annexation synoptic diagram.
Embodiment
As figure, on the periphery of the cylindrical aluminium bar 1 of φ 50mm * 100mm, be processed into the spiral half slot of φ 5, stopple coupon 2 is in half slot, and aluminium bar inside is porose, places heating wire 3 and the pt100 temperature sensor 7 of 50W in the hole respectively.The thermostat of using as post bake 10 is provided with heating member 8 and thermal detector 9, is provided with measuring cell 11 and microbial membrane sensor 5 in the sea water bath 4 of thermostat, and the import of measuring cell links to each other with stopple coupon, and outlet links to each other with peristaltic pump 6.
