Description

Technical Field

[0001] This utility model belongs to the field of constant temperature bath technology, and more specifically, it relates to a constant temperature bath for heating glass test tubes. Background Technology

[0002] Thermostats, as devices capable of creating a stable temperature environment for air or liquids at a constant temperature, are widely used in industries such as petroleum, chemical, bioengineering, and pharmaceuticals and food. The temperature control system of a thermostat typically includes key components such as temperature sensors, controllers, and actuators. These components work together to ensure the thermostat accurately maintains the set temperature, providing essential stable temperature conditions for various experiments and production processes. However, in constant-temperature experiments, existing thermostat structures reveal some significant drawbacks: when using a conventional thermostat to heat glass test tubes containing experimental reagents, the test tubes come into contact with the inner wall of the thermostat, affecting the accuracy of the experimental results. Furthermore, when the glass test tubes are removed after heating, residual water on the outer wall of the tubes drips down and splashes onto the experimental table, requiring additional cleaning and significantly reducing overall work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a constant temperature bath for heating glass test tubes, so as to avoid the glass test tubes from coming into contact with the inner wall of the constant temperature bath, and at the same time to prevent water remaining on the outer wall of the glass test tubes from splashing onto the experimental table.

[0004] The thermostatic bath for heating glass test tubes provided by this utility model includes a bath body and glass test tubes. An induction heater is installed inside the bath body, and a controller is installed on the outside. The controller and the induction heater are connected by an electrical control method. A mounting frame is provided inside the bath body, and four sets of first fixing slots are provided on the inner wall of the bath body. The first fixing slots are symmetrically distributed on the front and rear sides of the bath body. Fixing blocks are provided on both sides of the mounting frame. By embedding the fixing blocks into the first fixing slots, the mounting frame is installed and fixed on the inner wall of the bath body. An insertion tube is provided on the mounting frame, and the glass test tube passes through the insertion tube and is installed on the mounting frame.

[0005] Furthermore, a flow guiding device is provided on one side of the tank. The flow guiding device includes an insulation layer, with an end cap hinged to the top of the insulation layer and a collection tank connected to the bottom. A set of grates is provided inside the insulation layer. The bottom of the collection tank is connected to the tank body through a flow guiding pipe.

[0006] Furthermore, two sets of support plates are provided on the inner wall of the tank. These two sets of support plates are symmetrically distributed in the tank. The support plates support L-shaped partitions, and the three sides of the partitions are connected to the inner wall of the tank.

[0007] Furthermore, a rubber stopper is provided at the upper end of the glass test tube; a thermometer is installed in the insertion hole of the rubber stopper.

[0008] Furthermore, the collection tank has two flow-guiding slopes; the flow-guiding device is provided with a second fixing groove. When the mounting frame is placed into the flow-guiding device, the mounting frame and the glass test tube are installed and fixed in the flow-guiding device by embedding the fixing block into the second fixing groove. At this time, the lower end of the glass test tube is in contact with one of the flow-guiding slopes of the collection tank.

[0009] Furthermore, a stepped hole is provided at the top of the grate.

[0010] Furthermore, the top of the tank is covered with an insulation cover, and a sealing ring is provided between the tank and the insulation cover, with the sealing ring embedded in the tank.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model uses a mounting rack to securely place the glass test tube inside the rack and fix the rack to the inner wall of the tank, thereby achieving reliable fixation of the glass test tube. Then, the water in the tank is used to heat the reagent inside the glass test tube at a constant temperature.

[0013] 2. During the heating process, the temperature of the reagent can be detected by a thermometer. If a large deviation in temperature is detected, timely adjustments can be made to ensure the stability and accuracy of the heating process.

[0014] 3. By setting a second fixing groove, this utility model achieves stable fixation of the glass test tube and the mounting rack in the flow guiding device; when liquid adheres to the glass test tube, the liquid can slowly flow downwards and drip onto the flow guiding slope of the collection groove, and then be smoothly collected through the flow guiding pipe, avoiding splashing onto the experimental table.

[0015] Therefore, this invention has the positive effects of preventing the glass test tube from contacting the inner wall of the constant temperature bath, thus improving the heating effect, and at the same time, preventing water remaining on the outer wall of the glass test tube from splashing onto the experimental table, thus improving work efficiency.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] As attached Figure 1-7 As shown, the constant temperature bath for heating glass test tubes provided by this utility model includes a bath body 1 and a glass test tube 7. An induction heater 11 is installed inside the bath body 1, and a controller 14 is installed on the outside. The controller 14 is connected to the induction heater 11 by an electrical control method. A mounting frame 9 is provided inside the bath body 1, and four sets of first fixing slots 13 are provided on the inner wall of the bath body 1. The first fixing slots 13 are symmetrically distributed on the front and rear sides of the bath body 1. Fixing blocks 92 are provided on both sides of the mounting frame 9. By embedding the fixing blocks 92 into the first fixing slots 13, the mounting frame 9 is installed and fixed on the inner wall of the bath body 1. An insertion tube 91 is provided on the mounting frame 9. The glass test tube 7 passes through the insertion tube 91 and is installed on the mounting frame 9.

[0027] Among them, such as Figure 5 As shown, four sets of first fixing grooves 13 are provided on the inner wall of the tank 1, and the first fixing grooves 13 are symmetrically distributed on the front and rear sides of the tank 1; as Figure 7 As shown, fixing blocks 92 are provided on both sides of the mounting frame 9, such as Figure 4 As shown, by embedding the fixing block 92 into the first fixing groove 13, the mounting frame 9 is installed and fixed on the inner wall of the groove 1. Multiple sets of glass test tubes 7 placed in the groove 1 can be taken out together by the mounting frame 9, or several sets of glass test tubes 7 can be taken out from the groove 1 and placed into the flow guiding device 5. The mounting frame 9 is used to fix and install the glass test tubes 7 in the groove 1 and the flow guiding device 5.

[0028] Among them, such as Figure 2 As shown, a flow guiding device 5 is provided on one side of the tank 1. The flow guiding device 5 includes an insulation layer 51, with an end cap 53 hinged to the top of the insulation layer 51 via a hinge 52, and a collection tank 54 connected to the bottom. A set of grates 56 is provided inside the insulation layer 51. The bottom of the collection tank 54 is connected to the tank 1 via a flow guiding pipe 55. The insulation layer 51, the end cap 53, and the collection tank 54 together form a sealed space. When liquid adheres to the glass test tube, the liquid can slowly flow downwards, dripping onto the flow guiding slope of the collection tank 54, and then be smoothly collected through the flow guiding pipe 55, avoiding splashing onto the experimental table.

[0029] Among them, such as Figure 3 and Figure 4 As shown, two sets of support plates 12 are installed on the inner wall of the tank 1. These two sets of support plates 12 are symmetrically distributed front and back within the tank 1. L-shaped partitions 4 are supported on the support plates 12, and three sides of the partitions 4 are connected to the inner wall of the tank 1. The bottom of the tank 1 is filled with water. The partitions 4 isolate the liquid from the space above the tank 1. When the thermostatic bath is being maintained, items can be placed on the partitions 4 for temperature control. Items placed on the partitions 4 will not come into contact with the water in the tank 1. Removing the partitions 4 facilitates the refilling of water into the tank 1.

[0030] Among them, such as Figure 3 As shown, a rubber stopper 8 is provided at the upper end of the glass test tube 7; a thermometer 6 is installed in the insertion hole of the rubber stopper 8. The rubber stopper 8 is cylindrical, and its size matches the diameter of the upper end of the glass test tube 7. An insertion hole is provided at the central axis of the rubber stopper 8, through which the thermometer 6 passes and is fixedly connected. After the thermometer 6 is fixed by the rubber stopper 8 and placed inside the glass test tube 7, the thermometer 6 does not contact the inner wall of the glass test tube 7, avoiding direct heat transfer between the thermometer 6 and the glass test tube 7, thereby ensuring the accuracy of the temperature reading when the thermometer 6 measures temperature.

[0031] Among them, such as Figure 6As shown, the collection tank 54 has two flow-guiding slopes; the flow-guiding device 5 is provided with a second fixing groove 57. When the mounting frame 9 is placed into the flow-guiding device 5, the mounting frame 9 and the glass test tube 7 are installed and fixed in the flow-guiding device 5 by embedding the fixing block 92 into the second fixing groove 57. At this time, the lower end of the glass test tube 7 is in contact with one of the flow-guiding slopes of the collection tank 54. The top of the grate 56 has a stepped hole; when the thermometer 6 is placed into the flow-guiding device 5, the thermometer 6 is installed and fixed on the grate 56 by placing the rubber stopper 8 in the stepped hole of the grate 56. At this time, the lower end of the thermometer 6 is in contact with another flow-guiding slope of the collection tank 54. After the thermometer 6 and the glass test tube 7 are taken out of the tank body 1 and placed into the flow-guiding device 5, the liquid adhering to the thermometer 6 and the glass test tube 7 flows slowly downward to the flow-guiding slope of the collection tank 54. The liquid is recovered to the tank body 1 by the flow-guiding pipe 55 connected to the bottom of the collection tank 54, realizing the recycling of the liquid.

[0032] Among them, such as Figure 3 As shown, the top of the tank 1 is covered with an insulation cover 2, and the tank 1 and the insulation cover 2 are sealed with a sealing ring 3, which is embedded in the tank 1. The insulation cover 2 is placed on top of the tank 1 to heat and keep the reagent at a certain temperature.

[0033] In use, this invention first fills the constant temperature bath 1 with water to a certain height, and then controls the induction heater 11 to heat the water to a specified temperature and maintain the temperature via the controller 14. Next, the glass test tube 7 is inserted into the insertion tube 91 of the mounting rack 9, and the glass test tube 7 is placed in the bath 1 along with the mounting rack 9. The mounting rack 9 is fixed on both sides to the first fixing groove 13 provided on the inner wall of the bath 1, which can prevent the glass test tube 7 from contacting the inner wall of the constant temperature bath and improve the heating effect. Next, the heat-insulating cover 2 is placed on top of the tank 1 to heat and maintain the reagent at a certain temperature. During this period, the temperature of the reagent in the glass test tube 7 is monitored using a thermometer 6 to check for any significant deviations and adjustments are made promptly. After the specified heat-insulating time, the heat-insulating cover 2 and end cap 53 are opened, and the glass test tube 7 and the mounting rack 9 are removed from the tank 1 and placed into the flow guiding device 5. The mounting rack 9 is fixed in place by the second fixing groove 57. At this time, the bottom of the glass test tube 7 is in contact with the flow guiding slope of the collection tank 54. The liquid adhering to the glass test tube 7 flows slowly downwards to the flow guiding slope of the collection tank 54, and the liquid is collected back into the tank 1 by the flow guiding pipe 55 connected to the bottom of the collection tank 54. Finally, after the liquid adhering to the outer wall of the glass test tube 7 has mostly dried, it is thoroughly wiped dry before the reagent in the glass test tube 7 can be used. This avoids water remaining on the outer wall of the glass test tube splashing onto the experimental table, improving work efficiency.

[0034] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired beneficial effect can be implemented. All the induction heaters 11 and controllers 14 mentioned above are common commercially available components. When purchasing and using them, simply follow the instruction manual purchased with the product to connect them for operation; therefore, further details are omitted here.

[0035] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
