Description

Technical Field

[0001] This utility model relates to the field of simulation testing equipment technology, and in particular to a high-efficiency cyclic evaluation simulation device for constant temperature electrophoretic paint. Background Technology

[0002] The main purpose of electrophoretic paint aging test is to evaluate the durability and stability of electrophoretic paint under specific environmental conditions to ensure product quality and long-term reliability.

[0003] Existing electrophoretic paint aging tests only include open-air stirring experiments, which have drawbacks such as the lack of shear force in the stirrer and long cycle time. These tests cannot effectively simulate problems such as sedimentation and filter bag clogging after the aging of the bath solution in the field. Therefore, new products often experience sedimentation and membrane clogging issues during market promotion, and this risk cannot be effectively identified during application evaluation. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency cyclic testing simulation device for constant temperature electrophoretic paint, which can at least solve one of the above-mentioned problems.

[0005] According to one aspect of the present invention, a high-efficiency cyclic evaluation simulation device for constant-temperature electrophoretic paint is provided, comprising at least: The tank has an internal cavity for holding the paint liquid; The mixing mechanism includes at least a stirrer disposed inside the tank and used for mixing the paint liquid; The automatic temperature control mechanism can automatically adjust the temperature of the paint liquid inside the tank; The automatic liquid control mechanism can automatically adjust the liquid level of the paint in the tank.

[0006] In some embodiments, the automatic temperature control mechanism includes a first controller, a temperature sensor, and a cooling assembly. The probe end of the temperature sensor extends into the receiving cavity. The temperature sensor is electrically connected to the first controller. The cooling assembly cooperates with the tank and can cool the paint liquid in the tank under the control of the first controller.

[0007] In some embodiments, the cooling assembly includes a deflector for guiding cooling water, the deflector being disposed around the outer periphery of the tank.

[0008] In some embodiments, the cooling assembly further includes a cooling water supply pipe, a cooling water return pipe, a first control valve, and a second control valve. The inlet end of the guide plate is connected to the circulating water inlet end via the cooling water supply pipe. The first control valve cooperates with the cooling water supply pipe and is electrically connected to the first controller. The outlet end of the guide plate is connected to the circulating water outlet end via the cooling water return pipe. The second control valve cooperates with the cooling water return pipe. Thus, during the circulation test of electrophoretic paint tank liquid and other paint liquids, a constant temperature circulation can be achieved through the automatic temperature control mechanism. The constant temperature is set by the first controller. If the temperature detected by the temperature sensor is higher than the set value, the automatic temperature control mechanism is activated. Through the interlocking action of the temperature sensor, the first controller, and the first control valve, cooling water is controlled to flow through the guide plate to achieve cooling, thus completing the automatic temperature adjustment work and maintaining the temperature of the paint liquid in the tank at the ideal value.

[0009] In some implementations, the baffle is arranged in a spiral pattern on the outer periphery of the tank.

[0010] In some embodiments, the constant temperature electrophoretic paint high-efficiency cycle evaluation simulation device also includes an outer jacket structure fitted around the outer periphery of the tank, and a guide plate is installed on the outer jacket structure.

[0011] In some embodiments, one end of the guide plate is fixedly connected to the outer wall of the tank, and the other end can generate physical tension under the water pressure of the cooling water flowing through the guide plate to fit the outer jacket structure.

[0012] In some embodiments, a V-shaped groove is formed on the upper surface of the baffle. This type of baffle design allows the cooling water to fully contact the cylinder, reducing the likelihood of dead zones and scaling, and increasing the cooling area.

[0013] In some embodiments, the automatic liquid control mechanism includes a circulating shear pump, a second controller, a liquid level sensor, and a third control valve. The inlet of the circulating shear pump is connected to the third control valve and then to the outlet located at the bottom of the tank. The outlet of the circulating shear pump is connected to the inlet located on the middle or upper side wall of the tank. The probe of the liquid level sensor extends into the receiving cavity. The circulating shear pump, the liquid level sensor, and the third control valve are all electrically connected to the second controller. Thus, by setting the target liquid level value through the second controller and starting the automatic liquid control mechanism, the paint liquid in the tank flows out from the bottom outlet under the action of the circulating shear pump, then flows back into the tank from the inlet on the middle or upper side wall of the tank, forming a circulation. Through the interlocking action of the third control valve, the liquid level sensor, and the circulating shear pump, the paint liquid is circulated at a constant speed, thereby achieving the purpose of constant liquid level circulation.

[0014] In some embodiments, the stirring mechanism further includes a drive element for driving the stirrer to perform stirring actions.

[0015] The beneficial effects of this utility model are: 1. Short testing cycle and high efficiency: The use of a circulating shear pump provides efficient shearing and circulation, which greatly accelerates the aging process of the paint, shortens the verification cycle, and enables rapid verification of new products. 2. High predictive accuracy: This evaluation system, through strong shear cycling and constant temperature control, is more in line with the actual production scenario on site. It can effectively stimulate and identify the potential risks of product sedimentation and filter bag blockage, with high overlap and more realistic and reliable results. 3. High degree of automation: Through automatic temperature control mechanism and automatic liquid control mechanism, precise control of constant temperature and constant liquid level is achieved during the test, reducing human intervention and ensuring the stability of test conditions and the repeatability of results; 4. High efficiency, energy saving and environmental protection: The unique spiral guide plate design increases the heat exchange area, eliminates dead flow angles and scaling risks, and has a high energy utilization rate; at the same time, the guide plate can also slow down the flow, control the water flow to pass through at a uniform speed, and achieve a full cooling effect. 5. The entire system is a closed-loop test, which effectively avoids the spillage of volatile organic compounds during the test, making it more environmentally friendly and scientific.

[0016] 6. Simple structure and low cost: The structure of this utility model is reasonable, the components are easy to obtain and process, the operation is convenient, the manufacturing cost is low, and it is easy to promote and use.

[0017] 7. It can be used in various working conditions, including laboratory bath liquid circulation testing and manufacturing workshop material mixing. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model will now be described clearly and completely with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, this utility model discloses a constant temperature electrophoretic paint high-efficiency cycle evaluation simulation device, the core of which consists of a tank 1, a stirring mechanism 2, an automatic temperature control mechanism 3 and an automatic liquid control mechanism 4.

[0024] The tank 1 is the main body of the device, and its interior forms a cavity 101 for holding the paint liquid, such as the electrophoretic paint bath liquid to be tested. The tank 1 has an outlet 102 at its bottom and an inlet 103 on its upper or middle side wall. The tank 1 is in a closed state, which effectively prevents the leakage of volatile organic compounds, making it more environmentally friendly, scientific, and energy-efficient.

[0025] A stirring mechanism 2 is used to stir the liquid in the tank. In this embodiment, the stirring mechanism 2 may include a mechanical stirrer 201 driven by a drive element 202 (such as a motor). In a more preferred embodiment, the function of the stirring mechanism 2 can be achieved by the circulating shear pump 404 in the automatic liquid control mechanism 4 described below, that is, strong stirring and shearing are achieved through external circulation of the liquid.

[0026] The automatic temperature control mechanism 3 is used to achieve constant temperature control during the testing process. It includes a temperature sensor 302 that extends into the receiving cavity 101, a first controller 301 electrically connected to the temperature sensor 302, and a cooling assembly. The cooling assembly cooperates with the tank 1 and can cool the paint liquid in the tank 1 under the control of the first controller 301.

[0027] The constant temperature electrophoretic paint high-efficiency cycle evaluation simulation device of this utility model also includes an outer jacket structure 5 fitted around the outer periphery of the tank body 1.

[0028] The cooling assembly includes a guide plate 6, a cooling water supply pipe 303, a first control valve 304, a cooling water return pipe 305, and a second control valve 306, all housed within the outer jacket structure 5. The inlet end of the guide plate 6 is connected to the circulating water inlet end via the cooling water supply pipe 303. The first control valve 304 is coupled to the cooling water supply pipe 303 and electrically connected to the first controller 301. The outlet end of the guide plate 6 is connected to the circulating water outlet end via the cooling water return pipe 305. The second control valve 306 is coupled to the cooling water return pipe 305.

[0029] During the cyclic testing of paint solutions such as electrophoretic paint tank liquid, constant temperature circulation can be achieved through automatic temperature control mechanism 3. The constant temperature is set by the first controller 301. If the temperature detected by the temperature sensor 302 is higher than the set value, the automatic temperature control mechanism 3 is activated. Through the interlocking action of temperature sensor 302, first controller 301 and first control valve 304, the cooling water is controlled to flow through the guide plate 6 to achieve cooling, thus completing the automatic temperature adjustment work and keeping the temperature of the paint solution in the tank at the ideal value.

[0030] Combination Figure 2 and Figure 3 The guide plate 6 is spirally wrapped around the outer periphery of the tank 1, and a V-shaped groove 601 is formed on the upper end face of its cross-section. This structure enhances the rigidity of the guide plate and optimizes the flow channel. One end of the guide plate 6 is fixedly connected to the outer wall of the tank 1 by welding or other means, and the other end, after cooling water is introduced, can be tightly attached to the inner wall of the outer jacket structure 5 by water pressure, thereby forming a highly efficient spiral closed flow channel, maximizing the heat exchange area between the cooling water and the tank 1, and eliminating dead flow angles.

[0031] Preferably, the deflector plate 6 is made of a high thermal conductivity copper alloy.

[0032] Preferably, the tank body 1 is 6 mm thick, the outer jacket structure 5 is 25 mm wide, and the jacket layer is designed with a guide plate 6, which is 25 mm wide and 3 mm thick.

[0033] The automatic liquid control mechanism 4 is used to maintain a stable liquid level inside the tank. It includes a circulating shear pump 404, a second controller 401, a liquid level sensor 402, and a third control valve 403. The inlet of the circulating shear pump 404 is connected to the outlet 102 at the bottom of the tank through the third control valve 403, and its outlet is connected to the inlet 103 on the side wall of the tank. The liquid level sensor 402 extends into the receiving cavity 101 to monitor the liquid level. The circulating shear pump 404, the liquid level sensor 402, and the third control valve 403 are all electrically connected to the second controller 401. The first controller 301 and the second controller 401 can be two independent PLC controllers, or they can be integrated into the same PLC (Programmable Logic Controller).

[0034] Preferably, the first control valve 304 is a temperature control valve (TV), which is a valve used to regulate and control the temperature of fluid in the system. The valve is controlled by a first controller 301, which receives input from a temperature sensor and adjusts the valve accordingly. The second control valve 306 is an on / off control valve (XV). The third control valve 403 is a flow control valve (FV). The working principle of this utility model: During testing, the electrophoretic paint bath solution and other paint solutions are added to the receiving cavity 101 of tank 1. The automatic liquid control mechanism 4 is activated, and the second controller 401 sets the target liquid level. The circulating shear pump 404 operates, drawing the bath solution from the bottom outlet 102, pressurizing it through the circulating shear pump 404, and then injecting it back into tank 1 through the inlet 103, creating a strong circulating shear. This process simultaneously realizes the function of the stirring mechanism 2. During this process, if the temperature sensor 302 of the automatic temperature control mechanism 3 detects that the bath solution temperature is higher than the set value of the first controller 301, the first controller 301 will instruct the first control valve 304 to open wider, increasing the flow rate of cooling water through the spiral guide plate 6, thereby efficiently and uniformly cooling tank 1 and quickly returning the temperature to the set value. The entire testing process is carried out in a closed system with constant temperature and constant liquid level automatic control, which can quickly and accurately assess the aging stability and clogging tendency of the electrophoretic paint bath solution.

[0035] The constant-temperature electrophoretic paint high-efficiency cycle evaluation simulation device of this invention has at least the following advantages over the prior art: 1. Short testing cycle and high efficiency: The use of a 404 circulating shear pump provides efficient shearing and circulation, which greatly accelerates the aging process of the paint, shortens the verification cycle, and enables rapid verification of new products. 2. High predictive accuracy: This evaluation system, through strong shear cycling and constant temperature control, is more in line with the actual production scenario on site. It can effectively stimulate and identify the potential risks of product sedimentation and filter bag blockage, with high overlap and more realistic and reliable results. 3. High degree of automation: Through the automatic temperature control mechanism 3 and the automatic liquid control mechanism 4, precise control of constant temperature and constant liquid level is achieved during the test, reducing human intervention and ensuring the stability of test conditions and the repeatability of results; 4. High efficiency, energy saving and environmental protection: The unique spiral guide plate 6 design increases the heat exchange area, eliminates dead flow angles and scaling risks, and has a high energy utilization rate; at the same time, the guide plate 6 can also slow down the flow, control the water flow to pass through at a uniform speed, and achieve a full cooling effect. 5. The entire system is a closed-loop test, which effectively avoids the spillage of volatile organic compounds during the test, making it more environmentally friendly and scientific.

[0036] 6. Simple structure and low cost: The structure of this utility model is reasonable, the components are easy to obtain and process, the operation is convenient, the manufacturing cost is low, and it is easy to promote and use.

[0037] 7. It can be used in various working conditions, including laboratory bath liquid circulation testing and manufacturing workshop material mixing.

[0038] The device of this invention, under the action of the automatic temperature control mechanism 3 and the automatic liquid control mechanism 4, can achieve constant temperature circulation and constant liquid level circulation of paint liquids such as electrophoretic paint tank liquid. At the same time, the test cycle is shortened by the uniform and efficient shearing circulation of the circulating shear pump 404, reducing process energy consumption and energy waste. The system is tested in a closed state to avoid the overflow of volatile organic compounds, which is more environmentally friendly, scientific and energy-saving. It also enables rapid verification of new products and faster market promotion. It avoids the risk of membrane blockage and bag blockage due to the failure to identify potential uncertainties in the early stage, thereby improving economic benefits and customer satisfaction.

[0039] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
