[0028] The following combinationFigures 1 - 3 Describe a temperature-controlled constant temperature reaction device of the present utility model.

[0029] This embodiment provides a temperature-controlled constant temperature reaction device, including: a box body 1, a reaction tank 2, a liquid storage tank 3, a heating device 6 and a controller 10.

[0030] Among them, a temperature measuring device, which can be a temperature sensor, is arranged in the box body 1, and a water inlet 11 and a water outlet 12 are respectively arranged on both sides of the box body 1; the reaction tank 2 is arranged in the box body 1, and the bottom of the reaction tank 2 can be immersed in the liquid in the box body 1; one side of the liquid storage tank 3 is connected to the water inlet 11 through a first pipeline 4, a water pump 8 and a flow regulating valve 9 are arranged on the first pipeline 4, and the flow regulating valve 9 is arranged between the water inlet 11 and the water pump 8, and the liquid storage tank 3 is connected to the water outlet 12 through a second pipeline 5; the heating device 6 is connected to the first pipeline 4, which can be an electric heater, and is used for heating the liquid entering the box body 1; the controller 10 is electrically connected to the temperature measuring device, the flow regulating valve 9 and the heating device 6.

[0031] In the present utility model, the box body 1, the first pipeline 4, the liquid storage tank 3 and the second pipeline 5 are connected in sequence to realize the circulating flow of the liquid. By using the temperature measuring device to detect the liquid temperature in the box body 1 in real time, and through the controller 10 to feedback and regulate the flow regulating valve 9 and the heating device 6, the liquid temperature in the box body 1 is adjusted, and finally the liquid level and temperature are kept constant, so as to provide a uniform and constant temperature environment for the reaction tank 2 through water bath heat exchange; in addition, through the liquid storage tank 3, it is ensured that the system has sufficient liquid supply to meet the circulating demand, and it can buffer the liquid volume change caused by temperature change, avoiding damage to the pipeline due to excessive pressure. When the liquid temperature rises and the volume increases, the excess liquid can flow into the liquid storage tank 3, thus avoiding excessive pressure in the pipeline. By storing and releasing the liquid, the liquid storage tank 3 can adjust the pressure in the system and maintain the stable operation of the system.

[0032] During operation, the water pump 8 ensures the liquid circulation. After the heating device 6 is turned on to heat the liquid and raise the temperature, the liquid enters the reaction tank 2, and then the temperature value of the temperature measuring device is monitored. Since there will be heat loss during the liquid flow in the pipeline, after feedback by the temperature measuring device, the controller 10 continuously adjusts. The controller 10 ensures the constant temperature of the liquid in the box body 1 by controlling the power of the heating device 6 and the water pump 8, automatically compensates and adjusts to the set temperature value, and keeps the temperature constant.

[0033] The above-mentioned reaction tank 2 is integrally in a conical structure. By connecting with the box body 1, a structure is formed in which the upper part is the reaction tank 2 for chemical product reaction, and the bottom is a constant temperature water tank for maintaining constant temperature. Thus, the bottom and part of the side of the reaction tank 2 are immersed in the constant temperature water tank. This structure is convenient for connection and can maximize the immersion of the reaction tank 2 in the constant temperature water tank, having a large heat exchange area.

[0034] Furthermore, a cooling device 7 is connected to the second pipeline 5. The cooling device 7 can be an existing refrigeration equipment, and the cooling device 7 is electrically connected to the controller 10.

[0035] With such a setting, when it is necessary to provide a low-temperature reaction environment for the reaction tank 2, the heating device 6 is turned off, and the cooling device 7 connected to the second pipeline 5 is turned on to cool the liquid flowing out of the box body 1. After the liquid is cooled, it enters the liquid storage tank 3 and then enters the box body 1. The controller 10 issues an instruction to control the opening degree of the flow regulating valve 9 to keep the liquid level in the box body 1 constant. Then, the temperature value in the box body 1 is fed back through the temperature measuring device. The controller 10 ensures a constant temperature by controlling the opening degree of the flow regulating valve 9 and the power of the water pump 8, automatically compensating and adjusting to the set temperature value and maintaining a constant temperature to achieve the low-temperature constant temperature mode; when it is necessary to provide a high-temperature reaction environment for the reaction tank 2, the cooling device 7 is turned off, and the heating device 6 is turned on. Thus, through the control of the heating device 6 and the cooling device 7 by the controller 10, the high-temperature constant temperature mode and the low-temperature constant temperature mode of the reaction tank 2 are respectively realized.

[0036] In this embodiment, electromagnetic valves 16 are provided on both the first pipeline 4 and the second pipeline 5. The opening of the electromagnetic valves 16 is controlled by the controller 10 to control the opening of the corresponding first pipeline 4 and second pipeline 5. For example, when the controller 10 controls the electromagnetic valve 16 of the first pipeline 4 to open and the electromagnetic valve 16 of the second pipeline 5 to close, when the heating device 6 is in the open state, the liquid to be heated enters the box body 1 until the bottom of the reaction tank 2 is immersed in the liquid. Then, the controller 10 opens the electromagnetic valve 16 of the second pipeline 5 to make the liquid in the box body 1 flow out. By further controlling the opening degree of the flow regulating valve 9, the liquid level in the box body 1 is kept constant, and the liquid circulation process is realized, and the liquid level in the box body 1 is constant and at a constant temperature.

[0037] Furthermore, a liquid level gauge 13 is provided in the box body 1, and the liquid level gauge 13 is electrically connected to the controller 10. With such a setting, the liquid level gauge 13 is used to measure the liquid level in the box body 1 to ensure that the reaction tank 2 is in full contact with the liquid and achieve the best water bath heat exchange effect. When the liquid in the box body 1 reaches the preset height, the liquid level gauge 13 sends a signal to the controller 10, and the controller 10 controls the electromagnetic valve 16 of the second pipeline 5 to open to discharge the liquid in the box body 1 to keep the liquid level in the box body 1 constant. By adjusting the opening degree of the flow regulating valve 9, the power of the water pump 8, the heating device 6 or the cooling device 7, the effects of constant liquid level and constant temperature in the box body 1 are finally achieved.

[0038] Furthermore, a liquid level gauge 13 is also provided in the liquid storage tank 3. The liquid level gauge 13 is electrically connected to the controller 10 and is used to measure the liquid level in the liquid storage tank 3 to ensure that an appropriate amount of liquid is stored, avoiding the liquid level in the liquid storage tank 3 being too high or too low to meet the liquid circulation requirements in the system.

[0039] In some embodiments, the temperature measuring device includes a first thermometer 14 and a second thermometer 15. The first thermometer 14 is disposed on one side of the box body 1 near the water inlet 11, and the second thermometer 15 is disposed on one side of the box body 1 near the water outlet 12.

[0040] With such an arrangement, the temperature at the water inlet 11 is measured by the first thermometer 14, and the temperature value at the water outlet 12 is measured by the second thermometer 15, so that accurate temperature data at two different positions, namely the water inlet 11 and the water outlet 12, can be obtained, which helps to more precisely understand the water temperature change in the box body 1, meet the requirement of precise temperature control, and facilitate timely regulation of the liquid temperature.

[0041] The temperature-controlled constant-temperature reaction device provided in this embodiment can realize both high-temperature constant-temperature mode and low-temperature constant-temperature mode. During operation, first, the solenoid valve 16 of the first pipeline 4 is opened, and the liquid enters the box body 1. When the liquid level gauge 13 detects that the liquid level reaches the preset position, it sends a signal to the controller 10. The controller 10 issues an instruction to open the solenoid valve 16 of the second pipeline 5, and at the same time controls the opening degree of the flow regulating valve 9 to keep the liquid level in the box body 1 constant. By monitoring the temperature values of the two thermometers in the box body 1, the controller 10 continuously adjusts the power of the water pump 8 and the heating device 6 or the cooling device 7 to ensure that the liquid temperature in the box body 1 reaches the set value and remains constant.

[0042] Refer to Figure 2 , in some embodiments, flanging handles 17 are provided on both sides of the reaction tank 2, which facilitates convenient movement after use; and a reinforcing frame 18 is provided on the outer edges of the box body 1 and the reaction tank 2 to improve the strength and stability of the overall structure.

[0043] Furthermore, the height of the water inlet 11 is greater than the height of the water outlet 12, which ensures that the liquid entering the box body 1 through the water inlet 11 has a higher water level. The water outlet 12 can be close to the bottom of the box body 1 to ensure that the liquid in the box body 1 is discharged as much as possible. In some embodiments, the box body 1 is 240 mm high, the height of the water inlet 11 is 180 mm, and the height of the water outlet 12 is 43 mm.

[0044] In some embodiments, the opening of the reaction tank 2 is set as a conical structure, and the included angle A between the two sides of the opening is 30 - 50°. As Figure 3 shown, the opening of the reaction tank 2 has a conical flared structure, which is beneficial for the material to conveniently enter and exit the reaction tank 2, and the cross-section of the opening is rectangular, and the included angle A between the opposite sides is 30° - 50°, preferably 40°.

[0045] Optionally, the box body 1 and the reaction tank 2 are integrally formed, which is convenient for processing and manufacturing, and improves the stiffness and stability of the overall structure.
