Description

Technical Field

[0001] The invention relates to the technical field of chemical testing, in particular to a chemical testing platform with self-circulating water. Background Art

[0002] In chemical experiments, circulating water is often used to achieve multiple functions, such as temperature control, reaction promotion, and resource conservation. For example, in a high- and low-temperature circulating water bath, circulating water circulates within a set temperature range through a heating and cooling system, providing a stable temperature environment for experiments and ensuring the accuracy and reliability of experimental results. In a reactor, circulating water maintains the heat generated by the reaction, ensuring the reaction temperature, preventing high-temperature explosions during the reaction, and ensuring the purity and quality of the reaction products.

[0003] In the prior art, chemical test benches utilize a recyclable water bath heating device to heat different test tubes to promote reactions. A dedicated clamping structure is required to clamp and fix the different test tubes, and then the test tubes are placed inside a water bath for heating. This process requires operation on multiple test tubes of different specifications, which takes up a large amount of test bench space and requires more manual operation, increasing the difficulty of the experiment. On the other hand, when heating some glass test tubes, the test tubes often burst due to excessive temperature differences, which poses a certain risk. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a self-circulating water chemical test bench to solve the problems raised in the above background technology.

[0029] When the present invention is used, the chemical test tube 9 used in the experiment is placed in the corresponding clamping and positioning component 4, and the chemical test tube 9 is clamped and fixed by rotating the screw rod 21 and the anti-slip belt 17. Then, the subsequent water bath heating process can be carried out. The heated water is injected into the water bath tank 28 through the water bath circulation system 5 on the surface of the operating table 2. At this time, the clamping and positioning component 4 is manually controlled to move downward until the bottom of the chemical test tube 9 containing the chemical reagent is pressed against the surface of the preheating mechanism 6, and pressed downward until the side of the chemical test tube 9 is pressed against the end of the preheating mechanism 6. At this time, the preheating treatment can be carried out, and after the preheating is completed, it continues to move downward until it is embedded in the water bath tank 28, and the heating process is completed with the help of the internal hot water.

[0030] In this embodiment, the clamping and positioning assembly 4 includes a slider 10, an extension plate 15, and an anti-slip strip 17.

[0032] In this embodiment, the water bath circulation system 5 includes an electric heating box 23 and a circulation pump 25. The electric heating box 23 is installed on the surface of the operating table 2. The interior of the water bath 28 is integrally formed with multiple partitions 29, and the water bath 28 can divide the internal cavity into multiple independent areas by the partitions 29. The hot water inside each independent area is separated from each other. The interior of the electric heating box 23 is connected to one end of the interior of the water bath 28 through a delivery pipe 27. A lower hanging plate 24 is welded to the bottom of the operating table 2. A circulation pump 25 is placed on the surface of the lower hanging plate 24. One end of the circulation pump 25 is connected to a return pipe 26. The return pipe 26 is connected to one end of the interior of the water bath 28, and the return pipe 26 and the delivery pipe 27 are both connected to the same separated area inside the water bath 28. The interior of the water bath 28 transfers heat from the higher temperature area to the lower temperature area on the other side through the partition 29. After the test tube is clamped by the clamping and positioning component 4, the clamping and positioning component 4 is directly controlled to drive the test tube to descend, and after it rests against the end of the preheating mechanism 6, the corresponding number of conical plates 35 can be pushed open with the help of pressure, so that the opening size of the top of the water bath tank 28 can be automatically matched according to the size of the test tube to be heated in the water bath, thereby reducing the probability of external contamination of the circulating water and extending the water change cycle during the water circulation process.

[0033] Specifically, the water inside is heated by the electric heating box 23 and then injected into the water bath 28 through the side delivery pipe 27. Figure 1 As described above, in this embodiment, the water bath 28 is divided into three areas by two partitions 29, and the heated high-temperature water flow is injected into the water bath 28 at the rightmost end through the delivery channel, while the hot water at the right end is transferred to the other two cavities in turn through the partitions 29. The temperature inside the water bath 28 can be divided into gradients. At the same time, the hot water at the rightmost end is extracted with the help of the circulation pump 25 at the bottom and circulated into the interior of the electric heating box 23, thereby achieving the purpose of continuous circulation heating.

[0034] In this embodiment, the preheating mechanism 6 includes a fan 30 and a push plate 33. The fan 30 is installed on one side of the surface of the water bath 28. The push plate 33 is inserted into the inner wall of the water bath 28. A spring rod 34 is welded to one end of the push plate 33, and the other end of the spring rod 34 is inserted into the inner wall of the water bath. A conical plate 35 is integrally formed on the top of the push plate 33. The rear end of the conical plate 35 is connected to a preheating pipe 36, and the preheating pipe 36 is connected to the air flow outlet end of the fan 30. The rear end of the blower 30 is connected to a first steam pipe 31 or a second steam pipe 32, and the first steam pipe 31 is connected to the inside of the water bath 28 on the side, and the second steam pipe 32 is directly connected to the internal top cavity of the electric heating box 23. The ends of the push plate 33 and the conical plate 35 are attached with a preheating plate 37, and the inner wall of the preheating plate 37 is provided with steam holes 38. The preheating plate 37 has an overall arc-shaped structure and is used to fit the surface of the chemical test tube 9. Multiple water baths 28 are provided, and the temperature is controlled to change in a gradient. Therefore, when facing an experimental scenario requiring high temperature heating, they can be heated and heated one by one. At the same time, the preheating effect can be achieved by recycling steam, reducing the probability of test tube bursting and making the water bath cycle heating process safer.

[0035] Specifically, after the chemical test tube 9 is moved downward by the clamping and positioning component 4, the part of the conical plate 35 that is in contact with the bottom will be pressed to one side until the push plate 33 is moved toward the side of the spring rod 34. The spring rod 34 is compressed until the bottom of the chemical test tube 9 is pressed against the end of the conical plate 35 and the push plate 33. At this time, the preheating plate 37 can be used to press against the surface of the chemical test tube 9. With the help of the fan 30, the steam inside the water bath 28 or the electric heating box 23 in a higher temperature range on one side is drawn into the steam pipe along the steam pipe and then blown out toward the inside of the preheating pipe 36. Finally, the steam is used to heat the surface of the chemical test tube 9 and the part of the preheating plate 37. The chemical test tube 9 is preheated in advance with the help of this temperature. After preheating is completed, the chemical test tube 9 can be further moved down and embedded in the hot water at the bottom, or the area of ​​the water bath 28 can be replaced and placed in a higher temperature area for further preheating.
