Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to an automatic temperature control device for water-based synthetic leather resin. Background Technology

[0002] Resin synthesis is a widely used process in the chemical industry, involving various chemical reactions, including polymerization and cross-linking. These reactions are highly sensitive to temperature changes; fluctuations in reaction temperature can lead to instability in the molecular structure of the product, thereby affecting the quality, performance, and production efficiency of the resin. Therefore, maintaining precise temperature control within the reaction vessel is crucial during resin synthesis.

[0003] Existing reactor temperature control systems typically rely on external heating or cooling media. While these systems can regulate the reaction temperature to some extent, the complex properties of the reactants and the rapid changes in reaction rates mean that temperature changes are often delayed or fluctuate significantly. This results in insufficient system sensitivity and response speed, making it difficult to match the reaction rate and respond to the temperature requirements during the reaction process in real time. Consequently, the reaction cannot be stabilized within the required temperature range, which in turn affects the effectiveness of the resin synthesis reaction and the quality of the final product.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0018] Reference Figure 1 An automatic temperature control device for water-based synthetic leather resin includes a cylindrical vessel 10 for containing materials. Inside the vessel 10 is a rotatable stirrer 11, which includes a stirring shaft extending into the vessel 10 and blades mounted on the stirring shaft. The top end of the stirring shaft extends out of the vessel 10 and is connected to a drive motor. A shell 20 is provided on the outer wall of the vessel 10, forming a sealed chamber 30 between the shell 20 and the vessel 10. A flowable medium is contained within the sealed chamber 30; in this embodiment, the medium is water. A cooling device 4 is provided on one side of the vessel 10. 0. The cooling device 40 includes a first pump body for drawing in or discharging the medium and a cooling unit for cooling the medium. A heating device 50 is provided on the other side. The heating device 50 includes a second pump body for drawing in or discharging the medium and a heating unit for heating the medium. The bottom of the vessel body 10 is provided with a discharge port 12 that communicates with the sealed chamber 30. An electromagnetic three-way valve 60 is provided at the discharge port 12. The electromagnetic three-way valve 60 includes a first pipeline interface 61 for connecting to the cooling device 40, a second pipeline interface 62 for connecting to the heating device 50, and an inlet and outlet 63 for the medium to enter and exit.

[0019] During application, according to the temperature requirements of the material, the electromagnetic three-way valve 60 will automatically open or close the corresponding interface according to the setting, so that the cooling device 40 or the heating device 50 can circulate and cool or circulate and heat the medium in the sealed chamber 30, thereby achieving precise control of the material temperature in the reactor body 10, stabilizing the material within the required temperature range, promoting the stable progress of the resin synthesis reaction, and ensuring the quality of the final product.

[0020] Reference Figure 1The housing 20 has a first interface 21 on one side, and the cooling device 40 has a second interface 41 on the top. The first interface 21 and the second interface 41 are connected by a first pipe 42. The housing 20 has a third interface 22 on the other side, and the heating device 50 has a fourth interface 51 on the top. The third interface 22 and the fourth interface 51 are connected by a second pipe 52. The cooling device 40 has a fifth interface 43 at the bottom, which is connected to the first pipe interface 61 via a third pipe 44. The heating device 50 has a sixth interface 53 at the bottom, which is connected to the second pipe interface 62 via a fourth pipe 54. In this embodiment, the cooling unit is a chiller (not shown in the figure), and the heating unit is an electric heater. (Not shown in the figure) The first pump body and the second pump body are respectively the first centrifugal pump (not shown in the figure) and the second centrifugal pump (not shown in the figure). The inlet of the first centrifugal pump is connected to the outlet of the chiller, and the outlet is connected to the second interface 41. The inlet of the chiller is connected to the fifth interface 43. The inlet of the second centrifugal pump is connected to the outlet of the electric heater, and the outlet is connected to the fourth interface 51. The inlet of the electric heater is connected to the sixth interface 53. A first solenoid valve (not shown in the figure) and a second solenoid valve (not shown in the figure) are respectively installed at the first interface 21 and the second interface 41. In order to ensure the accuracy of the medium circulation, a liquid level sensor (not shown in the figure) can also be installed in the sealed chamber 30 between the shell 20 and the vessel body 10.

[0021] During the cooling cycle, if there is no medium in the sealed chamber 30, firstly, open the first solenoid valve and the first pipe interface 61 of the solenoid three-way valve. Then, connect an external water source to the inlet and outlet 63 of the solenoid three-way valve. At this time, the first pump of the cooling device 40 starts to run, thereby drawing water into the chiller for cooling and delivering it to the sealed chamber 30. When the liquid in the sealed chamber 30 reaches the set capacity, the injection of external water source stops. At this time, the inlet and outlet 63 at the bottom of the solenoid three-way valve and the second pipe interface 62 are closed, and only the first pipe interface 61 is open, thereby realizing the cooling cycle and achieving the purpose of rapidly cooling the material in the vessel 10. The principle of heating the material in the vessel 10 is the same as above, so it will not be described in detail here.

[0022] It should be noted that the chiller, electric heater, centrifugal pump, solenoid valve and liquid level sensor mentioned above are all existing technologies, so their principles and structures will not be described in detail here.

[0023] Reference Figure 1A temperature sensor 23 is provided on one side of the shell 20, with its probe extending into the interior of the vessel body 10. A controller 13 and a material inlet 14 are located on the top of the vessel body 10. The controller 13 is electrically connected to the cooling device 40, the heating device 50, the electromagnetic three-way valve 60, the first electromagnetic valve, the second electromagnetic valve, and the temperature sensor 23. With this configuration, the controller 13 can monitor the temperature inside the vessel body 10 in real time and automatically adjust the operating status of the cooling device 40 or the heating device 50 according to temperature changes, thereby ensuring temperature stability during the reaction process and significantly improving the automation and accuracy of the reaction process.

[0024] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
