Description
Technical field
The utility model belongs to the Gas content determination techniques field of coal, and in particular to a kind of stripping gas measurement temperature control recirculated water
Bath apparatus, main function are to guarantee that the sample being put in the device can carry out gas desorption quantity measurement at a constant temperature.
Background technique
Constant water bath box is the requisite instrumentation of coal seam stripping gas assay, and entire desorption process must be in stationary temperature
It is carried out under environment, otherwise can cause very big error, and then influence the accuracy of entire Gas content measurement.Currently, each laboratory
Only there is heating function using the most water bath of more, commercial type, meeting when carrying out desorption experiment for summer in this way
There is the reservoir temperature that bath temperature is higher than setting.Moreover, heating method is bottom electric heater for heating, this heating method meeting
So that the temperature difference of entire water bath different depth is larger, it is not able to satisfy stripping gas measuring temperature and uniformly requires.
Summary of the invention
The utility model cannot cool down for existing water bath when environment temperature is higher than reservoir temperature and water bath
Internal different depth the problems such as there are the temperature difference, and then a kind of stripping gas measurement temperature control circulator bath device is provided, make water bath
It being capable of accurate temperature controlling and beautiful and generous.
The utility model adopts the following technical solution:
A kind of stripping gas measurement temperature control circulator bath device, including the water tank and control cabinet to become one, water tank
Interior middle and lower part is transversely provided with the bearing plate for load-bearing desorption sample, and bearing plate lower section, control cabinet bottom are equipped with heating system,
The heating system is U-shaped electrothermal tube；Water tank is circumscribed with refrigeration machine and circulating pump.
PLC controller is installed, PLC controller is connect with circulating pump processed, refrigeration machine, U-shaped electrothermal tube, control in control cabinet
Case facade is equipped with power key and respectively corresponds control loop pump, refrigeration machine, the refrigeration key of U-shaped electrothermal tube, heating key circulation
Key.
The storage water surface distance water tank top edge of the water tank is not less than 20cm.
The utility model has the following beneficial effects:
(1) device has refrigerating function, and when environment temperature is higher than required reservoir temperature, device can be cooled to storage automatically
Layer temperature realizes constant temperature desorption.
(2) device can carry out circulation up and down to internal water, realize even water temperature in entire cabinet.
(3) refrigeration of the device, recycle, set temperature, control system integration to a cabinet, it is beautiful and generous.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- water tank, 2- control cabinet, 3- temperature display, 4- circulation key, 5- refrigeration key, 6- heat key, 7- power supply
Key, 8- heating tube, 9- bearing plate.
Specific embodiment
As shown in Figure 1, the device by water tank, bearing plate, heating system, refrigeration system, the circulatory system, set warm system,
Control system composition.
Water tank is mainly used for water storage, places desorption sample, can carry out the desorption experiment of 8 samples simultaneously.
Bearing plate is lightweight aluminium sheet, in water tank lower part, desorbs sample for load-bearing, compressive resistance, which can guarantee, is filling sample
Aluminium sheet is indeformable when product, avoids bending contact heating tube, influences heating system.
Heating system is made of in water tank bottom U-shaped electrothermal tube, the heating for water.
Refrigeration system is mainly small-sized refrigerator, the refrigeration for water.
The circulatory system is mainly small circulating pump, for forming reflux up and down to the water in water tank, keeps water temperature uniform up and down.
If warm system is mainly used for being arranged and showing water temperature, constant temperature is fluctuated less than 0.1 DEG C.
Control system be mainly control equipment power supply, refrigeration, heating, circulation switch.
In order to guarantee equipment beauty, by above refrigeration system, the circulatory system, warm system is set and control system is fully integrated
To inside a control cabinet；Meanwhile being conveniently moving, small footprint is installed additional in bottom four corners.
The specific work process of the device are as follows:
It is added water into the device away from top edge 20cm, is turned on the power switch, setting temperature is reservoir temperature, is then opened
Heating switch, refrigeration switch, cycling switch, reach set temperature to temperature, and refrigeration system and heating system are automatically stopped work,
The circulatory system works on；Start desorption experiment then to the sample for placing to be desorbed in water tank.The device have automatic heating,
Refrigeration and circulatory function, can make device not influenced by ambient temperature, by the constant perseverance for realizing sample to reservoir temperature of water temperature
Temperature desorption.
