Description
Technical Field
The invention relates to an experiment and automatic analysis instrument and sample automatic pretreatment equipment in the biochemical field, in particular to a glass water bath tub structure with a closed heat-insulating layer for concentration.
Background
In chemical analysis test experiments, the concentration process of liquid samples is one of the most widely used experimental processes. There are two conventional ways of heating for concentration, one is dry heating, e.g. heating a metal bath such as an aluminum block. One is wet heating, such as a water bath or oil bath, etc. In wet heating, the heated container is uniformly and closely contacted with the heating medium, so that the heating efficiency is high, the heating stability is high, and the wet heating is not easily influenced by the temperature of the external environment. The water bath wet heating method has the advantages that the transparent glass water bath tub structure is more and more popular in recent years, and compared with the traditional metal water bath tub structure, the conditions such as the concentration state of a liquid sample, the water bath amount and the like can be more conveniently observed. And the glass water bath tub is superior to the traditional metal water bath tub in acid and alkali corrosion resistance. However, the glass water bath also has four pain points in use:
first, the use of the heat of the water bath of the conventional glass water bath is inefficient. The concentration process is a continuous heat consuming process, with borosilicate glass having a thermal conductivity comparable to or even higher than that of water. For example, the thermal conductivity of 6061 aluminum alloy is about 150W/(mK), the thermal conductivity of water is about 0.6W/(mK), the thermal conductivity of ordinary borosilicate glass is about 0.7W/(mK), the thermal conductivity of polytetrafluoroethylene is about 0.256W/(mK), and the thermal conductivity of air is about 0.0267W/(mK). Therefore, the heat of the water bath is easy to flow into a low-temperature environment through the glass, and particularly, the heating power of the water bath is low due to large loss, so that the temperature rise time of an experiment is prolonged, the instability of an experiment result is enhanced, and the energy consumption is increased.
Secondly, the inner wall of the traditional glass water bath tub above the liquid level is easy to fog or condense water drops, which affects the concentration process of observing the liquid sample. Because the ambient temperature is low, hot steam meets the glass inner wall of low temperature and can fog, and water drops are easily condensed on the hydrophilic glass surface.
Thirdly, the traditional glass water bath tub has large brittleness, and the breakage risk of the glass water bath tub is easily aggravated by the alternation of the cold and hot water in transportation and use, so that the problems of water leakage, electric leakage, user safety and the like are caused. This safety hazard of user injury should and must be addressed.
Fourth, the conventional glass water bath is transparent, and exposure of the liquid sample to bright light easily causes decomposition of the photosensitive sample, which results in failure of the experiment.
Disclosure of Invention

The glass water bath tub structure with the sealed heat-insulating layer for concentration is characterized in that: the glass water bath tub is formed by sequentially adhering four pieces of high-temperature-resistant borosilicate glass end to end, and is provided with a top opening and a bottom opening, the bottom opening is hermetically connected with a heating bottom plate, and the bottom of the heat-insulating layer is also sealed by the heating bottom plate.
The glass water bath tub structure with the sealed heat-insulating layer for concentration is characterized in that: the heating bottom plate is an aluminum alloy plate embedded with a heating element.

The glass water bath tub structure with the sealed heat-insulating layer for concentration is characterized in that: the organic glass protective cover is made of transparent glass or dark light-proof glass.
The glass water bath tub structure with the sealed heat-insulating layer for concentration is characterized in that: the top of the heat preservation and insulation layer is sealed by a fixed supporting plate, the fixed supporting plate can be used for placing a movable supporting plate, the movable supporting plate can be used for fixing a plurality of glass concentration cups, and the lower parts of the glass concentration cups can be immersed into the pure water bath in the glass water bath tub.
The glass water bath tub structure with the sealed heat-insulating layer for concentration is characterized in that: and upper sealing gaskets are respectively arranged between the organic glass protective cover and the glass water bath tub as well as between the glass water bath tub and the fixed supporting plate.
Compared with the prior art, the invention has the beneficial effects that:
firstly, the device realizes that the water bath heat in the glass water bath tub is used for the concentration process of the liquid sample to the maximum extent through the low heat conductivity of the closed heat-insulating layer and the organic glass protective cover, and solves the problems of large water bath heat loss, low heat utilization efficiency, insufficient concentration power, low water bath temperature rise speed, time waste, energy waste and the like in a low-temperature environment.
Secondly, the device of the invention achieves the purpose that the inner wall and the outer wall of the glass water bath tub do not generate temperature difference through the closed heat-insulating layer heated by the heated bottom plate. The problem of the inside liquid sample in the concentrated cup of glass can not be observed to the glass basin inner wall above the liquid level in ordinary glass bathtub because the inside and outside difference in temperature of glass easily produces condensation and hazing is solved.
Thirdly, the device solves the potential safety hazard problems of glass fragmentation, water leakage, electric leakage and the like of the glass water bath tub caused by transportation and artificial force ineffectiveness through the plasticity of the organic glass protective cover and the buffer performance of the closed heat-insulating layer.
Fourthly, the device solves the problem that the photolysis liquid sample is decomposed when the photolysis liquid sample is not concentrated in a dark place through the dark light-avoiding performance of the organic glass protective cover.

the heating bottom plate 3 is an aluminum alloy plate embedded with a heating element and is in sealing connection with the bottom opening of the glass water bath tub 1 through high-temperature-resistant and acid-alkali-resistant glass cement;
the organic glass protective cover 2 is transparent glass (convenient for directly observing the concentration condition inside the glass water bath tub 1 from the outer side) or dark light-resistant glass (required for concentrating some liquid samples 6 which cannot be illuminated) below 5 mm, and is respectively arranged at the outer side positions of four pieces of high-temperature resistant borosilicate glass so as to form a closed heat-insulating layer 8 between the organic glass protective cover 2 and the glass water bath tub 1, the bottom of the closed heat-insulating layer 8 is closed by a heating bottom plate 3 and is adhered into a whole by high-temperature resistant and acid and alkali resistant glass glue, the top of the closed heat-insulating layer 8 is closed by a fixed support plate 11 (made of aluminum alloy), and the inside can be closed gas or hollow;
the pure water bath 4 is arranged in the glass water bath tub 1, the pure water bath 4 can be heated by the heating bottom plate 3, and the temperature can be set to any value from room temperature to 100 ℃;
the glass concentration cup 5 is made of high-temperature-resistant borosilicate glass, is used for containing a liquid sample 6 and is arranged on a limiting hole of a movable supporting plate 7, and the lower half part of the glass concentration cup 5 is arranged in the pure water bath 4; the liquid sample 6 consists of a solvent and a solute, and under the heating of the pure water bath 4, the solvent is volatilized, and the solute is reserved;
the movable supporting plate 7 is an aluminum alloy plate, is erected on the fixed supporting plate 11 and is used for fixing the glass concentrating cup 5 so as not to be floated by the buoyancy of the pure water bath 4;
the sealed heat-insulating layer 8 is formed by an organic glass protective cover 2, a glass water bath tub 1, a heating bottom plate 3 and a fixed support plate 11 together, and plays a role in heat insulation by virtue of air (or a hollow structure) in the sealed heat-insulating layer and the low heat conductivity of organic glass;
an upper sealing washer 9 is arranged between the organic glass protective cover 2 and the glass water bath tub 1 and the fixed supporting plate 11, and a lower sealing washer 10 is arranged between the organic glass protective cover 2 and the glass water bath tub 1 and the heating bottom plate 3 to provide good sealing effect.
The implementation steps of the device of the invention are further described in the following with reference to the attached drawings.
The glass water bath tub 1 is internally added with sufficient normal-temperature pure water bath 4, the heating bottom plate 3 starts to heat, the temperatures of the pure water bath 4, the closed heat-insulating layer 8 (containing air in the embodiment), the glass concentration cup 5 and the liquid sample 6 are sequentially heated to the temperature required by the experiment, and the common temperature for the concentration experiment of the liquid sample 6 is between room temperature and 100 ℃. As required by the experiment, the response speed of the liquid sample 6 when the temperature is raised to the temperature set by the user is higher, and the time and the energy are saved. At this time, the larger the difference between the external environment temperature and the set temperature, the larger the heat loss, and the more time and energy are consumed by heating the soleplate 3 to maintain the experimental temperature of the whole system. At this point, the plexiglas protective cover 2 comes into play. At normal temperature, the heat conductivity coefficient of the pure water bath 4 is about 0.6W/(mK), the heat conductivity coefficient of the glass water bath tub 1 is about 0.7W/(mK), the heat conductivity coefficient of the organic glass protection cover 2 is about 0.18W/(mK), and the heat conductivity coefficient of the closed heat insulation layer is about 0.0267W/(mK). Therefore, the organic glass protective cover 2 and the sealed heat-insulating layer 8 add a barrier with low thermal conductivity for blocking heat loss for the pure water bath 4 and the glass water bath tub 1, thereby playing a heat-insulating effect and improving the heat use efficiency of the pure water bath 4.
Meanwhile, because of the existence of the closed heat-insulating layer 8 heated by the heating bottom plate 3, the temperature difference between the inner wall and the outer wall of the glass water bath tub 1 can not be generated, so that the surface of the glass above the liquid level in the glass water bath tub 1 is not easy to generate condensation and fogging, and the inner surface of the glass water bath tub 1 has good visibility all the time.
The plasticity of the organic glass protective cover 2 and the buffer performance of the closed heat-insulating layer 8 can also prevent potential safety hazards such as glass breakage, water leakage and electricity leakage caused by transportation and artificial force ineffectiveness of the glass water bath 1.
When light-resistant concentration is carried out on the light-sensitive liquid sample 6 which is easy to decompose when meeting light, the organic glass protective cover 2 can be quickly replaced by a dark light-resistant cover, so that the light-sensitive liquid sample 6 is always carried out under the light-resistant condition in the concentration process, and the smooth experiment is ensured.
Compared with the prior art, the invention has the following advantages:
firstly, the device realizes that the water bath heat in the glass water bath tub 1 is used for the concentration process of the liquid sample 6 to the maximum extent through the low heat conductivity of the closed heat-insulating layer 8 and the organic glass protective cover 2, and solves the problems of large water bath heat loss, low heat utilization efficiency, insufficient concentration power, low water bath temperature rise speed, time waste, energy waste and the like in a low-temperature environment.
Secondly, the device of the invention achieves the purpose that the temperature difference is not generated between the inner wall and the outer wall of the glass water bath tub 1 through the closed heat-insulating layer 8 heated by the heated bottom plate 3. The problem of the inside liquid sample 6 of glass condensation cup 5 inside can not be observed because the temperature difference easily produces condensation and hazing inside the glass basin inner wall above the liquid level in ordinary glass bathtub 1 inside because of glass inside and outside is solved.
Thirdly, the device solves the potential safety hazard problems of glass fragmentation, water leakage, electric leakage and the like of the glass water bath tub 1 caused by transportation and artificial force ineffectiveness through the plasticity of the organic glass protective cover 2 and the buffer performance of the closed heat-insulating layer 8.
Fourthly, the device solves the problem that the photolysis liquid sample 6 is decomposed when not being shaded and concentrated by the dark shading performance of the organic glass protective cover 2.
