Description

Technical Field

[0001] This utility model relates to the field of water bath heating devices for epoxy coating tanks, specifically a temperature control and regulation device for heating epoxy heavy-duty anti-corrosion coatings. Background Technology

[0002] Epoxy coatings are prone to crystallization and increased viscosity at low temperatures, which affects their application performance and curing effect. Water bath heating, as a gentle and uniform heating method, is widely used in the preheating and thawing process of epoxy coatings.

[0003] Current water bath epoxy coating heaters can utilize the heat from external liquids to heat and treat epoxy coatings, rapidly dissolving crystals in the coating and reducing the viscosity of the epoxy resin. However, a problem exists in the actual heating process: when traditional containers for storing epoxy coatings are placed in a water bath heater, some products float on the surface due to differences in the density of the epoxy coatings inside the container. This undoubtedly reduces the heat transfer efficiency of the water bath device for the epoxy coating containers. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a temperature control and regulation device for heating epoxy heavy-duty anti-corrosion coatings, so as to solve the problem that some products will float on the water surface due to the different densities of epoxy coatings inside the tank during the traditional water bath heating process. This undoubtedly solves the technical problem of low heat transfer efficiency of water bath devices for epoxy coating tanks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature control and regulation device for heating epoxy heavy-duty anti-corrosion coating, comprising a water bath, a cover plate provided above the water bath, a limiting component provided below the cover plate, the limiting component comprising a plurality of fixing frames, the plurality of fixing frames being fixedly connected to the bottom surface of the cover plate, a first placement frame and a second placement frame for placing an epoxy coating tank being sequentially fixedly connected below the fixing frames, and a lifting mechanism for lifting the cover plate being installed at the central axis of the water bath.

[0006] By adopting the above technical solution, the temperature control and regulation equipment effectively prevents epoxy coating tanks from floating in the water bath medium due to density differences by setting limit components and combining multiple fixed frames and layered placement frames. This ensures that the coating tanks are always completely immersed in the heated liquid, thereby significantly improving heat transfer efficiency and heating uniformity, and avoiding heat loss or incomplete crystallization and dissolution caused by partial exposure of the tank.

[0007] Furthermore, the surfaces of the first and second placement frames are uniformly provided with a plurality of slots for liquid flow.

[0008] By adopting the above technical solution, the slots on the surfaces of the first and second placement frames allow the water bath medium to flow freely, breaking the local thermal boundary layer and promoting the uniform distribution of heat around the tank. This ensures that there are no hot spots due to temperature differences during the heating process of the epoxy coating, thereby preventing local overheating from causing thermal damage or crystallization residue to the material, and significantly improving heating consistency and product quality.

[0009] Furthermore, several of the fixed frames are arranged in an equidistant ring along the central axis of the cover plate.

[0010] By adopting the above technical solution, the fixed frame is arranged in a ring at equal intervals along the central axis of the cover plate, which realizes the spatial symmetrical distribution of the paint tank, ensures that the heat field is evenly diffused in the water bath, and prevents uneven local heating caused by the deviation of the tank position, thereby improving the overall balance and stability of the heating process.

[0011] Furthermore, the lifting mechanism includes a support column, and the lower end of the support column is provided with a plurality of support rods, which are fixedly connected to the inner wall of the water bath.

[0012] By adopting the above technical solution, the support column of the lifting mechanism is fixedly connected to the inner wall of the water bath through the support rod to form a rigid support frame, providing high stability and torsional resistance, ensuring that there is no swaying or displacement during the lifting process of the cover plate, thereby ensuring accurate positioning and safe operation of the paint tank loading and unloading.

[0013] Furthermore, a sleeve is fixedly installed above the cover plate, and an electric actuator is installed on the inner side of the sleeve. The electric actuator is supported and installed on the upper end of the support column, and the support column is slidably fitted inside the sleeve. The electric actuator lifts the sleeve, the cover plate, the first placement frame, and the second placement frame.

[0014] By adopting the above technical solution, the electric actuator is installed on the upper end of the support column and sleeved inside the sleeve, which realizes precise lifting control. The cover plate is smoothly driven by electric driving force, ensuring that the process of immersing or lifting the paint tank is smooth and unobstructed, thereby improving the convenience of operation and response speed.

[0015] Furthermore, an electric heater is installed inside the lower part of the water bath, and a junction box is electrically connected to the electric heater on the outside of the water bath.

[0016] By adopting the above technical solution, the electric heater installed at the bottom inside the water bath is connected to the power supply through the junction box on the outside, providing stable and efficient heat output, ensuring that the water bath medium heats up quickly and maintains a constant temperature, thereby ensuring uniform heating and effective decrystallization of the epoxy coating.

[0017] Furthermore, a control box is installed on the upper outer side of the water bath, and the electric push rod and the electric heater are both electrically connected to an external power source through the control box.

[0018] By adopting the above technical solution, the control box is set on the upper outside of the water bath, and the electric actuator and electric heater are controlled by electrical connection to achieve centralized operation and parameter setting, ensuring that the lifting and heating processes are coordinated and synchronized, thereby improving the automation level and operation consistency of the equipment.

[0019] Furthermore, a number of temperature sensor probes are uniformly arrayed on the inner side of the water bath to feed back temperature signals to the controller.

[0020] By adopting the above technical solution, temperature sensor probes uniformly arrayed inside the water bath monitor the changes in medium temperature in real time and feed the signal back to the controller to achieve dynamic temperature control and ensure that the heating process is always kept within the set range, preventing temperature fluctuations from causing a decline in the performance of epoxy coatings or thermal aging.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. In this utility model, the fixing frame of the limiting component is arranged in a ring along the central axis of the cover plate. The first and second placement frames are arranged in layers to adapt to different tank sizes. Combined with the uniform grooves on the surface, the liquid can circulate freely, eliminating the problem of uneven heat conduction caused by the floating of the tank. This allows the epoxy coating tank to be completely submerged below the liquid surface in the water bath device, thereby improving the ease of use of the water bath temperature control device.

[0023] 2. In this utility model, the design of the water bath and the lifting mechanism provides rigid support through the support column and support rod, so that the sleeve driven by the electric push rod can accurately lift the cover plate, realize the stable immersion and quick loading and unloading of the paint tank, and avoid the risks of manual operation.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] In this embodiment:

[0032] A temperature control and regulation device for heating epoxy heavy-duty anti-corrosion coatings, such as Figure 1-5 As shown, the device includes a water bath 1, a cover 5 on top of the water bath 1, and a limiting component 6 below the cover 5. The limiting component 6 includes several fixing frames 601, which are fixedly connected to the bottom surface of the cover 5. Below the fixing frames 601, a first placement frame 602 and a second placement frame 603 for placing epoxy coating tanks are sequentially fixedly connected. A lifting mechanism 7 for lifting the cover 5 is installed at the central axis of the water bath 1. This temperature control device, by setting the limiting component 6, combined with multiple fixing frames 601 and layered placement frames, effectively prevents the epoxy coating tank from floating in the water bath medium due to density differences. This design ensures that the paint tank is always completely submerged in the heated liquid, thereby significantly improving heat transfer efficiency and heating uniformity. It avoids heat loss or incomplete crystallization and dissolution caused by partial exposure of the tank. At the same time, the integrated design of the lifting mechanism 7 and the water bath 1 with central positioning simplifies the loading and unloading process, reduces the labor intensity of operators, and enhances the overall stability of the equipment, preventing safety accidents caused by external shaking. The sealed connection structure between the cover plate 5 and the water bath 1 further ensures airtightness, reduces heat loss, and improves energy utilization efficiency. Moreover, the multi-level placement frame adapts to the flexibility of paint tanks of different sizes, supporting diverse industrial production needs.

[0033] See Figure 1 , Figure 2 , Figure 3The surfaces of the first placement frame 602 and the second placement frame 603 are uniformly provided with a plurality of slots 604 for liquid flow. The slots 604 on the surfaces of the first placement frame 602 and the second placement frame 603 allow the water bath medium to flow freely, break the local thermal boundary layer, promote the uniform distribution of heat around the tank, and ensure that there are no hot spots due to temperature differences during the heating process of epoxy coating. This prevents local overheating from causing thermal damage or crystallization residue to the material, greatly improving heating consistency and product quality. At the same time, the slot design enhances the fluid dynamics characteristics, reduces water flow resistance, and avoids tank displacement or shaking caused by poor medium flow. This structure also reduces the risk of scale buildup, extends the service life of the equipment, and the slot layout optimizes heat exchange efficiency, supports continuous production processes, and further improves the overall reliability of the equipment.

[0034] See Figure 1 , Figure 2 , Figure 3 Several fixed frames 601 are arranged in an equidistant ring along the central axis of the cover plate 5. This arrangement of the fixed frames 601 in an equidistant ring along the central axis of the cover plate 5 achieves a spatially symmetrical distribution of the paint tanks, ensuring that the heat field is uniformly diffused within the water bath 1. This prevents uneven heating caused by tank position deviations, thereby improving the overall balance and stability of the heating process. At the same time, this ring array optimizes the space utilization of the equipment, facilitates batch processing of multiple tanks, and is suitable for high-efficiency production environments. The connection method of the fixed frames enhances structural strength and reduces the impact of vibration.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 5 The lifting mechanism 7 includes a support column 701, with several support rods 702 at the lower end of the support column 701. The support rods 702 are fixedly connected to the inner wall of the water bath 1 to form a rigid support frame, providing high stability and torsional resistance. This ensures that the cover plate 5 does not swing or deviate during the lifting process, thereby ensuring accurate positioning and safe operation of the paint tank loading and unloading. At the same time, this support structure disperses mechanical stress and extends the life of key components. The center position positioning also enhances the coordination with the cover plate 5, optimizes the lifting smoothness, facilitates deployment in confined spaces, and the support structure is simple and easy to maintain, reducing later maintenance costs and improving the overall durability of the equipment.

[0036] See Figure 4 , Figure 5A sleeve 703 is fixedly installed above the cover plate 5. An electric actuator 704 is installed inside the sleeve 703. The electric actuator 704 is supported and installed on the upper end of the support column 701, and the support column 701 is fitted and slidably inside the sleeve 703. The electric actuator 704 lifts the sleeve 703, cover plate 5, first placement frame 602 and second placement frame 603. The electric actuator 704 is supported and installed on the upper end of the support column 701 and fitted inside the sleeve 703 to achieve precise lifting control. The cover plate 5 is smoothly driven by electric driving force to ensure smooth and unobstructed process of immersion or lifting of the paint tank, thereby improving the convenience of operation and response speed. At the same time, the guiding function of the sleeve 703 protects the internal mechanism from external contamination or corrosion, reduces friction loss and extends the life of the electric actuator. This integrated structure enhances the sealing and heat insulation effect and supports the automated operation mode, reducing the risk of human intervention.

[0037] See Figure 1 , Figure 2 , Figure 3 An electric heater 4 is installed inside the lower part of the water bath 1. A junction box 3 is connected to the electric heater 4 on the outside of the water bath 1. The electric heater 4 installed inside the lower part of the water bath 1 is connected to the power supply through the junction box 3 on the outside, providing stable and efficient heat output, ensuring that the water bath medium heats up quickly and maintains a constant temperature, thereby ensuring uniform heating and effective decrystallization of the epoxy coating. At the same time, the protective design of the junction box 3 isolates electrical components from the liquid environment, preventing leakage or short circuit accidents and improving the safety level of the equipment. The low-position layout of the electric heater 4 optimizes the heat convection path, enhances thermal efficiency, and the junction box facilitates external maintenance and quick repair.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A control box 2 is installed on the upper outer side of the water bath 1. The electric actuator 704 and the electric heater 4 are both electrically connected to an external power source through the control box 2. The control box 2 is located on the upper outer side of the water bath 1 and controls the electric actuator 704 and the electric heater 4 through electrical connection, realizing centralized operation and parameter setting, ensuring that the lifting and heating processes are coordinated and synchronized, thereby improving the automation level and operational consistency of the equipment. At the same time, the control box 2 integrates safety protection mechanisms, such as overload cut-off and emergency stop functions, to avoid equipment failure or personal injury caused by misoperation. Its external location facilitates daily monitoring and adjustment, reduces the risk of users coming into contact with high-temperature components, simplifies wiring management, and enhances system reliability and scalability.

[0039] See Figure 1 , Figure 2 , Figure 3The water bath 1 has several temperature sensor probes evenly arrayed on its inner side. These probes feed back temperature signals to the controller. The temperature sensor probes evenly arrayed on the inner side of the water bath 1 monitor the temperature changes of the medium in real time and feed the signals back to the controller to achieve dynamic temperature control. This ensures that the heating process is always kept within the set range, preventing temperature fluctuations from causing a decline in the performance of the epoxy coating or thermal aging. At the same time, the multi-probe layout covers different areas inside the tank, eliminating blind spots of temperature differences and improving the overall heating uniformity. Combined with the controller's automatic adjustment function, this enhances the system's response accuracy, reduces human intervention errors, and ultimately ensures product quality consistency and equipment operational stability.

[0040] The implementation principle of this embodiment is as follows: First, the target temperature is set through the control box 2. After the electric heater 4 is powered through the junction box 3, it heats the medium in the water bath 1. Then, the electric push rod 704 of the lifting mechanism 7 pushes the sleeve 703 to rise along the support column 701, which drives the cover plate 5 to open. The operator places the paint can in the placement frame of the limiting component 6. The electric push rod 704 lowers the cover plate 5 so that the can is completely immersed in the medium. The support rod 702 and the support column 701 ensure the stability of the lifting. During the heating process, the temperature sensor probe inside the can monitors the temperature in real time and feeds it back to the control box 2 for dynamic adjustment. At the same time, the slot 604 on the surface of the placement frame promotes heat exchange, and the limiting component 6 prevents the can from floating. After heating is completed, the lifting mechanism 7 raises the cover plate 5 to remove the paint can.
