Description
Technical field
A kind of electric-heated thermostatic water bath is the utility model is related to, belongs to Biochemical Lab's equipment technical field.
Background technology
Water-bath is applied to the experiment of the industrial and mining enterprises such as medical institutions, universities and colleges, scientific research department and chemical industry printing and dyeing, pharmacy
Room, it is mainly used in distillation in laboratory, dry, concentration and heated at constant temperature and other humid tests, is biology, laboratory, analysis
The indispensable instrument such as room, education and scientific research.
The temperature regulating range of water-bath typically at 5-100 DEG C, temperature sensor, temperature controller control under, heating temperature
Degree is not over 100 DEG C.However, when biology laboratory is tested, experimenter (mainly student) usually when in use, first
Energization forgets plus water, causes dry combustion method.In addition, after liquid evaporation is complete, also easily cause the hidden danger of dry combustion method.Although there is TEMP
The control of device, temperature controller, temperature will not be caused too high and cause fire, but long-time dry combustion method causes to waste, and easily make
Into parts damages, inadvertently, also easily personnel are caused to scald.
Utility model content
The purpose of this utility model is to provide a kind of electric-heated thermostatic water bath, and the electric-heated thermostatic water bath can be definitely effectively anti-
Only dry combustion method.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is：
A kind of electric-heated thermostatic water bath, including water-bath casing, some water tanks are provided with the water-bath casing, it is described
Tank outer wall is enclosed with insulation jacket, and the water tank bottom is provided with heater, and the heater connects with temperature control device
Connect, temperature control device control heating devices heat, the water tank bottom is provided with interlayer, conduction oil, the guarantor are marked with the interlayer
Warm chuck (material) is adiabatic cotton；On water-bath casing, pressure is provided with below the water tank by elastic mounting for the water tank
Force snesor, the pressure sensor are connected with temperature control device, and the signal of pressure sensor passes to temperature control device.
Preferably, the material of the water-bath casing is steel plate.
On water-bath casing, pressure sensor, pressure sensing are provided with below water tank by elastic mounting for the water tank
Whether there is water in device detection water tank, when detecting pressure anomaly, it is meant that anhydrous in water tank, the then now letter of pressure sensor
Number send temperature control device to, temperature control device control heater is no longer heated and (realized by deenergization), so as to effectively
Prevent dry combustion method.
Conduction oil in interlayer can effectively play the function of temperature storage to water tank so that water tank temperature is to greatest extent
Keep constant.Water tank outer layer covers have adiabatic cotton, have completely cut off the object heat transfer that water tank is in contact with it, even if dry combustion method be present,
Even temperature reaches 100 DEG C, reduces injury to greatest extent.
In order to further prevent dry combustion method, water-level gauge is installed in the water tank, the water-level gauge is connected with temperature control device, institute
The signal for stating water-level gauge passes to temperature control device.Whether there is water in water-level gauge detection water tank, when detecting no water level, then now
The signal of water-level gauge sends temperature control device to, and temperature control device control heater is no longer heated, so as to effectively prevent dry combustion method.
Pressure sensor, water-level gauge independent control, even if one of them has problem, do not interfere with anti-dry to temperature control device yet
Effect.
When being had no water or little water in water tank, temperature control device control alarm sends alarm.That is the signal transmission of temperature control device
To alarm, alarm equipment alarm.Meanwhile the display that the temperature control device control is connected thereto, display show water shortage letter
Breath.
The utility model multiple-protection, the effect of anti-dry can be effectively played, improve security when student uses.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of electric-heated thermostatic water bath, including water-bath casing 3, the material of water-bath casing 3 is steel plate,
Four water tanks 2 are provided with the water-bath casing 3, lid 1 is mounted on each water tank 2, each water tank 2 can be assigned respectively
Give different temperatures.The water tank 2 is by elastic mounting on water-bath casing 3, and rubber cushion is mainly in the horizontal direction to water tank 2
Play fixation.
The bottom of water tank 2 is provided with heater, and the heater is connected with temperature control device (containing processor),
Temperature control device controls heating devices heat.
The outer wall of water tank 2 is enclosed with insulation jacket, and the insulation jacket is adiabatic cotton, the thermal insulation of the outer layer covers of water tank 2
Cotton, completely cut off the object heat transfer that water tank 2 is in contact with it, though dry combustion method be present, or even temperature reaches 100 DEG C, to greatest extent
Reduce injury.
The bottom of water tank 2 is provided with interlayer 5, is marked with conduction oil in the interlayer 5, and the conduction oil in interlayer 5 can be effectively
The function of temperature storage is played to water tank 2 so that keep constant to the maximum temperature limit of water tank 2.
The lower section of water tank 2 is provided with pressure sensor 4, and the in the vertical direction of pressure sensor 4 plays support to water tank 2
Effect, rather than plays a supporting role on rubber cushion vertical direction to water tank 2, and otherwise pressure sensor 4 can not well, even can not
Play a role.The pressure sensor 4 is connected with temperature control device, and the signal of pressure sensor 4 passes to temperature control device.Pressure passes
Sensor 4 detect water tank in whether have water, when detecting pressure anomaly (i.e. without water pressure), it is meant that it is anhydrous in water tank, then this
When pressure sensor 4 signal send temperature control device to, temperature control device control heater is no longer heated, so as to effectively anti-
Only dry combustion method.
In order to further prevent dry combustion method, water-level gauge 6 is installed in the water tank 2, the water-level gauge 6 connects with temperature control device
Connect, the signal of the water-level gauge 6 passes to temperature control device.Whether there is water in water-level gauge detection water tank 2, when detecting no water level
When, then now the signal of water-level gauge 6 sends temperature control device to, and temperature control device control heater is no longer heated, so as to have
Effect prevents dry combustion method.
Pressure sensor 4, the independent control of water-level gauge 6, even if one of them has problem, do not interfere with to temperature control device yet
To the effect of anti-dry.Meanwhile when (or few water) anhydrous in water tank, temperature control device control alarm sends alarm, and will lack
Water information sends to connected display and shown.
Heater and temperature control device are prior art, are repeated no more.Temperature control device can contain processor, or single
Only processor, now single processor and temperature control device, alarm, display etc. are connected.
Above-described embodiment does not limit the utility model in any way, every by the way of equivalent substitution or equivalent transformation
The technical scheme of acquisition is all fallen within the scope of protection of the utility model.
