Abstract
The utility model discloses a temperature control device for a water bath kettle in a laboratory, which comprises a stainless steel water bath kettle, wherein a heat insulation layer is arranged in the water bath kettle, the water bath kettle is provided with a heating ring, a temperature measuring probe of the water bath kettle penetrates through two stainless steel circular rings welded on the inner wall of the water bath kettle, a tetrafluoro floating ball is arranged at the top end of the temperature measuring probe, and the temperature control device of the water bath kettle can ensure that the temperature measuring probe cannot topple over and can float up and sink along with the height of a water level, so that the temperature can be accurately measured and controlled.
Description
The technical field is as follows:
the utility model relates to a temperature control device of a water bath kettle in a laboratory.
Background art:
the water bath pot is mainly used for distilling, drying, concentrating and warm-soaking chemical drugs or biological products in a laboratory, can also be used for constant-temperature heating and other temperature tests, and is a necessary tool for biology, heredity, viruses, aquatic products, environmental protection, medicine, sanitation, laboratories, analysis rooms and educational and scientific research.
The heating water bath kettle of the chemical synthesis laboratory is special, and is often required to be heated to high temperature and be heated for a long time when chemical reaction is carried out, and four bottles are required to be placed in the water bath kettle, so that the temperature measuring probe does not have a fixed installation position and can often fall outside the water bath kettle, once the temperature measuring probe cannot measure the water bath temperature, a heating system can continuously heat, so that the temperature of a reaction system can be continuously increased, and even material flushing and burning accidents occur. Therefore, the water bath kettle is convenient for fixing the temperature measuring probe, and the height of the temperature measuring probe can be automatically adjusted along with the water level.
The utility model content is as follows:
in order to solve the technical problem, the utility model provides a device for fixing a temperature probe.
The temperature control device of the laboratory water bath kettle is realized as follows: the main body is a stainless steel pot, the periphery of the stainless steel water bath pot is provided with an annular heat-insulating layer, a heating ring connected with a power line is placed at the bottom of the water bath pot, a reaction bottle for experiments is placed in the water bath pot, the residual space in the water bath pot is filled with heated water bath, a temperature measuring probe connected with a data line is vertically placed in the water bath pot, and the water bath pot is placed on a magnetic stirrer.
A first stainless steel ring is welded at a position 3cm away from the upper edge of the stainless steel water bath kettle, a second stainless steel ring is welded at a position 5cm away from the upper edge of the stainless steel water bath kettle, and the diameters of the two stainless steel rings are both 1 cm.
The temperature measuring probe penetrates through the two stainless steel circular rings and then penetrates through the tetrafluoro floating ball with the diameter of 3cm, and the floating ball is fixed at the position 5cm away from the top end of the temperature measuring probe.
After water is added into the water bath, the probe slowly rises along with the water level after the water level rises, and the probe slowly falls along with the water level after the water level slowly falls along with the heating of the water bath.
The utility model has the following beneficial effects:
because the two stainless steel circular rings are used for fixing the temperature measuring probe, the temperature measuring probe can be prevented from falling outside the water bath, and because the floating ball is arranged at the front end of the temperature measuring probe, the temperature measuring probe can be ensured to be always below the water surface. The two aspects of control can ensure accurate temperature measurement; and the water bath pot is provided with a heat insulation jacket, so that the heat insulation effect is achieved, and the energy consumption is reduced.
Description of the drawings:
in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention.
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a stainless steel ring welded to the inner wall of a water bath;
FIG. 3 is a schematic view of a stainless steel ring;
fig. 4 is a schematic view of a tetrafluoro float ball.
The reference numbers in the figure are 1, a water bath 2, a water bath heat preservation layer 3, a heating ring 4, a water surface 5 in the water bath, a heating ring power line 6, a reaction bottle 7, a data line 8 of a temperature probe, a temperature probe 9, a first stainless steel ring 10, a second stainless steel ring 11, a floating ball 12 arranged at the lower end of the temperature probe and a magnetic stirrer.
The specific implementation mode is as follows:
in order that those skilled in the art will better understand the disclosure, the utility model will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the device is a temperature control device of a reaction bottle 6, and comprises a stainless steel water bath pot 1, wherein a heat insulation layer 2 is arranged outside the water bath pot, a heating ring 3 is arranged at the bottom of the water bath pot and is connected with a heating power line 5, water 4 for heating or cooling is added into the water bath pot, and a temperature probe 8 connected with a temperature measurement data line 7 is arranged in the water bath pot.
Two stainless steel rings 9 and 10 with the diameter of 1cm are welded at the positions 3cm and 5cm away from the upper edge of the inner wall of the water bath kettle, a temperature measuring probe penetrates through the two stainless steel rings and then penetrates through a tetrafluoro floating ball 11 with the diameter of 3cm, and the floating ball is fixed at the position 5cm away from the top end of the temperature measuring probe.
The working principle is as follows: the temperature measuring probe penetrates through the two stainless steel circular rings, the two stainless steel circular rings are fixed to ensure that the temperature measuring probe keeps vertical and cannot topple over, and the polytetrafluoroethylene floating ball is arranged at the front section of the temperature measuring probe to ensure that the temperature measuring probe rises and falls along with the water level and is always below the water level; after the heating ring is powered on, the heating water bath begins to be heated, when the water quantity is evaporated at high temperature, the water quantity is reduced, and at the moment, the temperature measuring probe is also reduced along with the reduction of the water level, so that the accuracy of temperature measurement can be ensured.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
