Description

Technical Field

[0001] This utility model mainly relates to the field of temperature control technology, specifically a temperature control and regulation device. Background Technology

[0002] In the coatings industry, especially in the preparation and application of cathodic electrophoretic coatings, temperature control is a key factor in ensuring the quality of coating curing. The traditional cathodic electrophoretic coating curing process requires strict temperature control (usually 160-180℃) to ensure the full deblocking of the blocked isocyanate and its effective crosslinking with the epoxy resin. The stability and uniformity of temperature during this process have a crucial impact on the quality of the final coating film.

[0003] However, in the existing technology, the temperature control device suffers from low temperature control accuracy and poor stability due to problems such as slow response of the heating / cooling system and uneven temperature distribution, which affects the curing effect of the coating and the quality of the paint film. Therefore, a temperature control and adjustment device is proposed. Utility Model Content

[0025] Please refer to the appendix carefully. Figure 1-4 A temperature control and regulation device, wherein a heat insulation cover 2 is installed on the outside of the reaction chamber 1, and a temperature regulating cavity 3 is formed between the reaction chamber 1 and the heat insulation cover 2.

[0026] Specifically, the temperature regulating chamber 3 is filled with a temperature-conducting liquid, and a first temperature sensor 301 for measuring the temperature of the temperature-conducting liquid is installed inside the temperature regulating chamber 3. Two sets of first annular nozzles 4 are installed inside the temperature regulating chamber 3 on the outside of the reaction chamber 1, and a heating box mechanism 5 connected to the two sets of first annular nozzles 4 is provided on the outside of the heat insulation cover 2. Two sets of second annular nozzles 6 are installed inside the temperature regulating chamber 3 on the outside of the reaction chamber 1, and a cooling box mechanism 7 connected to the two sets of second annular nozzles 6 is provided on the outside of the heat insulation cover 2.

[0027] To further explain, the bottom of the heat insulation cover 2 is provided with a drain port for discharging the heat-conducting liquid, and a sealing cap is installed at the opening end of the drain port.

[0028] In this embodiment, as Figure 1 and Figure 3 As shown, the top of the reaction chamber 1 is provided with a cover 101, the cover 101 is provided with a feed port, and the reaction chamber 1 is equipped with a stirring rod structure 102 for stirring the materials. The reaction chamber 1 is also equipped with a second temperature sensor 103 for detecting the internal temperature.

[0029] Through the above structure, the design of the feed inlet makes the feeding of materials more convenient and improves the operating efficiency. The stirring rod structure 102 can continuously stir the materials in the reaction chamber 1, ensuring that the materials are heated evenly, improving the reaction efficiency and product quality. The second temperature sensor 103 can monitor the temperature in the reaction chamber 1 in real time, ensuring that the reaction is carried out under suitable temperature conditions. Accurate temperature control is a key factor in ensuring the quality of chemical reaction products such as coatings. The setting of the second temperature sensor 103 helps to improve the quality of the final product.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the first annular nozzle 4 includes an annular tube 401, which is connected to the inner side of the heat insulation cover 2 via a connecting fixing block, facilitating the installation of the annular tube 401. Several sets of nozzles 402 are installed on the inner side of the annular tube 401, and a connector 403 is provided on one side of the annular tube 401. The first annular nozzle 4 and the second annular nozzle 6 have the same structure, and the first annular nozzle 4 and the second annular nozzle 6 are arranged alternately.

[0031] With the above structure, the staggered arrangement of the first annular nozzle 4 and the second annular nozzle 6 can ensure that the temperature-conducting liquid is evenly distributed in the temperature-regulating chamber 3, avoiding local temperatures that are too high or too low.

[0032] In this embodiment, as Figure 1As shown, the heating box mechanism 5 includes a heating box body 501, a feed inlet is provided on the top of the heating box body 501, and a heating plate 502 for heating the heat-conducting liquid is provided inside the heating box body 501. A first delivery pump 503 for conveying the heat-conducting liquid inside the heating box body 501 is installed on the top of the heating box body 501, and the first delivery pump 503 is connected to two sets of first annular spray pipes 4 through a first connecting pipe 504.

[0033] With the above structure, the heating plate 502 can heat the heat-conducting liquid evenly, so that the heat-conducting liquid reaches the required temperature, thereby improving the accuracy of temperature control. The first delivery pump 503 quickly delivers the heated heat-conducting liquid to the first annular nozzle 4 through the first connecting pipe 504, thereby regulating the internal temperature of the temperature regulating chamber 3.

[0034] In this embodiment, as Figure 1 and Figure 4 As shown, the cooling box mechanism 7 includes a cooling box body 701. The cooling box body 701 is provided with a cooling pipe 702 for cooling the heat transfer liquid. The cooling pipe 702 is connected to a refrigerator 7021. The refrigerator 7021 is existing technology and will not be described in detail. The refrigerator 7021 is used to provide cooling capacity to the cooling pipe 702 to cool the heat transfer liquid. A second delivery pump 703 is installed on one side of the cooling box body 701 for transporting the heat transfer liquid inside the cooling box body 701. The second delivery pump 703 is connected to two sets of second annular nozzles 6 through a second connecting pipe 704.

[0035] Through the above structure, the cooling pipe 702 and the refrigerator 7021 are combined to cool the heat transfer liquid evenly and effectively, ensuring that the heat transfer liquid reaches the required low temperature state. The second delivery pump 703 quickly delivers the cooled heat transfer liquid to the second annular nozzle 6 through the second connecting pipe 704, thereby regulating the internal temperature of the temperature regulating chamber 3. The cooling box mechanism 7 and the heating box mechanism 5 work together to control the temperature and flow rate of the heat transfer liquid, which helps to maintain the stable operation of the entire temperature control and regulation device, so that the temperature inside the reaction chamber 1 is in an ideal state.

[0036] In this embodiment, as Figure 1 and Figure 4 As shown, a liquid level sensor 8 for detecting the volume of the heat-conducting liquid inside the cooling box 701 and the heating box 501 is installed inside the cooling box 701 and the heating box 501. A third temperature sensor 801 is installed below the liquid level sensor 8. The lower side of the temperature regulating cavity 3 is connected to the interior of the cooling box 701 and the heating box 501 through a flow pipe 9. A matching valve is installed inside the flow pipe 9. The valve can be a solenoid valve structure for easy remote control in the future. The heating box mechanism 5 and the cooling box mechanism 7 are powered by independent power supplies to ensure efficient operation of the heating and cooling processes.

[0037] With the above structure, the liquid level sensor 8 is installed inside the cooling box 701 and the heating box 501 to monitor the volume of the heat transfer fluid inside the box in real time. When the volume inside the cooling box 701 and the heating box 501 is insufficient, the heat transfer fluid in the temperature regulating chamber 3 can be allowed to flow into the cooling box 701 and the heating box 501 by opening the valve inside the corresponding flow pipe 9. The heat transfer fluid circulates between the heating box mechanism 5, the temperature regulating chamber 3 and the cooling box mechanism 7 under the action of the delivery pump and the flow pipe 9. The pipeline layout is reasonable and the valve settings are appropriate to ensure that the heat transfer fluid is reasonably distributed. At the same time, high sealing materials and design are used to prevent the heat transfer fluid from leaking.

[0038] To further explain, the temperature inside and outside the reaction chamber 1 is monitored in real time by the first temperature sensor 301 and the second temperature sensor 103, and the data is transmitted to the controller. The controller automatically adjusts the working state of the heating chamber mechanism 5 and the cooling chamber mechanism 7 according to the preset temperature range and rate of change. The heated or cooled heat-conducting liquid is evenly sprayed through the first annular nozzle 4 and the second annular nozzle 6 to achieve precise temperature control.

[0039] The specific operating procedure of this utility model is as follows: First, materials are added to the reaction tank 1 through the feed inlet. After the device is started, the stirring rod structure 102 begins to stir the materials. The first temperature sensor 301 monitors the temperature of the heat-conducting liquid in the temperature-regulating chamber 3 in real time and transmits the data to the control system. When heating is required, the control system starts the heating box mechanism 5, and the heating plate 502 heats the heat-conducting liquid. The heated heat-conducting liquid is then transported to the first annular spray pipe 4 through the first delivery pump 503 and the first connecting pipe 504, and sprayed evenly in the temperature-regulating chamber 3. Conversely, when cooling is required, the refrigerator 7021 in the cooling box mechanism 7 cools the heat-conducting liquid through the cooling pipe 702. The cooled heat-conducting liquid is then transported to the first annular spray pipe 4 through the first delivery pump 503 and the first connecting pipe 504, and sprayed evenly in the temperature-regulating chamber 3. The second delivery pump 703 and the second connecting pipe 704 deliver the liquid to the second annular nozzle 6, which is also sprayed evenly into the temperature regulating chamber 3. The staggered arrangement of the first annular nozzle 4 and the second annular nozzle 6 ensures the uniformity of the temperature regulation effect. The liquid level sensor 8 and the third temperature sensor 801 monitor the volume and temperature of the heat-conducting liquid in the heating chamber 501 and the cooling chamber 701, respectively, to ensure the stable operation of the system. When the liquid level sensor 8 detects that the liquid volume inside the heating chamber 501 or the cooling chamber 701 is low, the valve in the flow pipe 9 on the corresponding side is opened to realize the circulation flow between the heat-conducting liquid in the temperature regulating chamber 3 and the heating chamber 501 and the cooling chamber 701, so as to maintain the continuous operation of the system.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
