Abstract
The utility model relates to a liquid constant temperature heating device applied to a water quality monitoring instrument. The liquid constant temperature heating device is characterized by comprising a heater, an aluminum block, a reagent tube and a temperature sensor, wherein the aluminum block is designed into a cylindrical structure, the outer side of the aluminum block is provided with a spiral groove from the 1/3 part of the right end to the left end, the reagent tube is wound into the spiral structure and is arranged in the spiral groove of the aluminum block, the heater is arranged at the right end of the aluminum block, and the temperature sensor is arranged at the left end of the aluminum block. The device has the advantage that the influence on the monitoring result caused by reagents and environment temperature is perfectly reduced.
Description
Technical field
The present invention relates to the water quality monitoring system of field of environment protection, relate in particular to a kind of liquid constant temperature heating arrangement that is applied in the water quality monitoring instrument.
Background technology
In water quality monitoring system, water sample to be monitored and environment temperature are larger on monitoring result impact, need to TWS to be monitored constant more than room temperature certain temperature, to reduce the impact of temperature.Existing resistance wire or heating water bath are because its power is high, quick heating, cryogenic thermostat control realizes relatively difficulty, for overcoming defects, the utility model provides a kind of novel liquid constant temperature heating arrangement, and this device reduces reagent and environment temperature well on the impact of monitoring result.
Summary of the invention
A kind of liquid constant temperature heating arrangement that is applied in the water quality monitoring instrument is characterized in that: comprise well heater, aluminium block, Reagent Tube, temperature sensor; Described aluminium block is designed to cylindrical structure, the outside of described aluminium block is designed with spiral groove from right-hand member 1/3 to left end, described Reagent Tube spirally-wound structure is fixed in the spiral groove of described aluminium block, described well heater is installed in the right-hand member of described aluminium block, and described temperature sensor is installed in the left end of described aluminium block.
As preferably, the spiral groove bottom surface of described aluminium block is designed to circular arc.
As preferably, the diameter of the spiral groove bottom surface circular arc of described aluminium block is corresponding with the diameter of Reagent Tube.
Description of drawings
Figure 1 shows that a kind of liquid constant temperature heating arrangement structural drawing that is applied in the water quality monitoring instrument
Embodiment
Figure 1 shows that a kind of liquid constant temperature heating arrangement that is applied in the water quality monitoring instrument, comprise well heater 1, aluminium block 2, Reagent Tube 3, temperature sensor 4; Wherein aluminium block 2 is designed to cylindrical structure, the outside of aluminium block 2 is designed with spiral groove 5 from right-hand member 1/3 to left end, Reagent Tube 3 spirally-wound structures are fixed in the spiral groove 5 of aluminium block 2, well heater 1 is installed in the right-hand member of aluminium block 2, temperature sensor 4 is installed in the left end of aluminium block 2, for detection of the temperature of aluminium block 2; The bottom surface of the spiral groove 5 of aluminium block 2 is designed to circular arc, and guarantee reagent pipeline and aluminium block are better fitted, and liquid is heated evenly in heating process, and the diameter of the spiral groove 5 bottom surface circular arcs of aluminium block 2 is corresponding with the diameter of Reagent Tube 3.During this utility model device work, because Reagent Tube 3 is large with the contact area of aluminium block 2, aluminium block is subjected to thermal velocity fast, is heated evenly, and the Reagent Tube that is installed in the aluminium block is heated evenly.
Embodiment disclosed herein is exemplary, and it only is for explanation that the utility model is made an explanation, and is not to restriction of the present utility model, and the improvement that those skilled in the art will envision that and expansion are included within the protection domain of the present utility model.
