Description

Technical Field

[0001] This application relates to electrophoretic coating, and more particularly to a thermostatic mixing device for electrophoretic paint solutions. Background Technology

[0002] In current electrophoretic coating technology, the temperature uniformity and mixing effect of the electrophoretic paint are crucial to the coating quality and equipment operation stability. Electrophoretic paint is a complex colloidal system composed of resin, pigment, additives and deionized water, and its physicochemical properties are significantly affected by temperature and concentration.

[0003] A search revealed Chinese Patent Publication No. CN208212961U, which discloses a cathodic electrophoretic paint adding and stirring device. The device includes a housing with a top cover at its upper end. A motor is connected to the middle of the top cover, and a stirring shaft is connected to the motor's output end. The stirring shaft is connected to the top cover via bearings and extends into the housing. Stirring branches are fixedly installed on the outer wall of the stirring shaft at equal intervals using bolts. This invention facilitates rapid adding of the electrophoretic paint by providing two feed hoppers. The motor drives the stirring shaft, stirring branches, and U-shaped support to rotate and stir rapidly, thereby increasing the stirring efficiency of the electrophoretic paint inside the housing. The U-shaped scraper close to the bottom of the housing and the scraper close to the inner wall of the housing prevent the electrophoretic paint from adhering to the inner wall of the housing during stirring, thus avoiding affecting the subsequent stirring effect.

[0004] Although the aforementioned patent facilitates rapid liquid addition by setting up two feed hoppers, and uses a motor to drive the stirring shaft, stirring branches, and U-shaped support to rotate and stir rapidly, thereby increasing the stirring efficiency of the electrophoretic paint inside the shell, the U-shaped scraper closely attached to the bottom of the shell and the scraper closely attached to the inner wall of the shell prevent the electrophoretic paint from sticking to the inner wall of the shell and affecting the subsequent stirring effect. The stirring shaft, stirring branches, and scraper are installed with bolts for easy disassembly and cleaning. Similarly, the stirring shaft, U-shaped support, and reinforcing rod are also installed with bolts, which also facilitates disassembly and cleaning. Here, the reinforcing rod provides support and reinforcement to the U-shaped support, preventing it from breaking during the electrophoretic paint stirring process, thus affecting the stirring effect. After mixing is complete, the mixed cathodic electrophoretic paint is discharged through the discharge pipe. Then, the top cover is vertically pulled upwards by a hydraulic cylinder with a connecting rod of the same length as the motor, thus separating the top cover from the housing. This facilitates the disassembly of the mixing branch, scraper, U-shaped bracket, and reinforcing rod for cleaning, preventing shaft seizure. The rubber pad at the bottom of the top plate acts as a buffer, preventing the motor from being damaged by hitting the top plate too quickly during the upward movement. It is highly practical and worthy of widespread promotion. However, the above text proposes mixing to achieve internal flow, which cannot solve the problem of uneven internal temperature. This leads to reduced mixing efficiency and increased energy consumption during use. Therefore, a constant temperature mixing device for electrophoretic paint liquid is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: Constant temperature mixing device for electrophoretic paint solution, refer to Figure 1 , Figure 3 and Figure 4The system includes a support base plate 1, with a mixing tank 2 fixedly connected to the top of the support base plate 1. The support base plate 1 serves as the basic support structure for the entire device, ensuring the stability and integrity of the equipment. The mixing tank 2 is made of corrosion-resistant material to adapt to the chemical properties of the electrophoretic paint. A heating mechanism 4 is fixedly connected inside the mixing tank 2. The mixing tank 2 serves as the main site for mixing and heating the electrophoretic paint, ensuring that the paint is fully mixed under constant temperature conditions. The heating mechanism 4 provides constant temperature heating for the paint in the mixing tank 2, ensuring that the paint is mixed at a suitable temperature. The heating mechanism 4 includes multiple coupling control columns 41, which serve as the control elements of the heating mechanism 4. Through coupling control, the system can achieve... For accurate temperature regulation, the outer left side of the coupling control column 41 is fixedly connected to the right side of the connecting plate 3. The inside of the coupling control column 41 is fixedly connected to the transmission line 42, which connects the coupling control column 41 and the guide plate 43 for heat transfer. The output ends of multiple transmission lines 42 are fixedly connected to the guide plate 43, which makes the heat evenly distributed in the paint liquid in the mixing tank 2. The inside of the guide plate 43 is fixedly connected to multiple inclined heating plates 44. The inclined heating plates 44 increase the heating area and improve the heating efficiency through the inclined design. The inside of the mixing tank 2 is fixedly connected to the cleaning component 45 for cleaning the inside of the mixing tank 2 to prevent paint residue and impurity accumulation. Specifically, the electrophoretic paint first flows into a mixing tank 2 made of corrosion-resistant material. The heating mechanism 4 inside the mixing tank 2 starts working. Multiple coupled control columns 41 act as control elements, transferring heat to the guide plate 43 through internal transmission lines 42. Multiple inclined heating plates 44 inside the guide plate 43 increase the heating area due to their inclined design, distributing heat evenly to the paint in the mixing tank 2 and heating the paint at a constant temperature. While being heated, the paint is mixed in the mixing tank 2. With the even distribution of heat, the paint is fully mixed at a suitable temperature. After the mixing is completed, the cleaning component 45 is activated to clean the inside of the mixing tank 2, preventing paint residue and impurity accumulation, and preparing for the next paint mixing and heating operation.

[0026] The cleaning assembly 45 includes two electrolyte plates 4501. Through electrolysis, the electrolyte plates 4501 effectively remove paint residue, impurities, and dirt from the inner wall of the mixing tank 2 and the surface of the equipment. The electrolyte plates 4501 are externally fixedly connected to both sides of the inside of the mixing tank 2. Multiple sensors 4502 are fixedly connected to the bottom inner side of the mixing tank 2, including integrated conductivity, viscosity, and particle size sensors 4502, used to monitor various parameters during the cleaning process, such as temperature and liquid level. A connecting plate 3 is fixedly connected to the top of the mixing tank 2, and a circulating filtration mechanism 6 is fixedly connected to the top of the supporting base plate 1. The circulating filtration mechanism 6 circulates and filters the paint and clean water in the mixing tank 2 to ensure the purity and quality of the paint. A supporting limit seat 9 is fixedly connected to the top of the supporting base plate 1, and a low-shear mixing mechanism 5 is fixedly connected to the top of the supporting limit seat 9. The paint liquid is mixed in a way that avoids excessive shearing and affecting its performance. The low-shear mixing mechanism 5 includes a magnetic coupling pump 51, which is the core power component of the low-shear mixing mechanism 5. The magnetic coupling pump 51 is responsible for transporting the paint liquid from the input end to the mixing tank 2. The bottom of the magnetic coupling pump 51 is fixedly connected to the top of the support limit seat 9. The output end of the magnetic coupling pump 51 is fixedly connected to the connecting input pipe 54. The connecting input pipe 54 transports the paint liquid output by the magnetic coupling pump 51 to the mixing tank 2 to ensure the smooth flow of the paint liquid. The top of the support base plate 1 is fixedly connected to a biomimetic impeller 52. The biomimetic impeller 52 simulates the fluid flow pattern in nature through biomimetic use to achieve low-shear mixing and ensure that the paint liquid is fully mixed in the mixing tank 2 without being subjected to excessive shearing. The outside of the mixing tank 2 is fixedly connected to a support plate 53. The support plate 53 serves as a support structure to ensure the stability and integrity of the equipment. Specifically, the magnetic coupling pump 51 is started, pumping the paint liquid to the mixing tank 2 through the connecting input pipe 54. The biomimetic impeller 52 simulates the natural fluid mode, and works with the low-shear mixing mechanism 5 to mix the paint liquid with low shear force. At the same time, the coupling control column 41 in the heating mechanism 4 transfers heat to the guide plate 43 through the transmission line 42. The paint liquid is uniformly heated by the inclined heating plate 44, so that it is fully mixed at a suitable temperature. During the mixing process, the circulation filtration mechanism 6 circulates and filters the paint liquid in the mixing tank 2 to ensure purity. After the mixing is completed, the electrolyte plate 4501 starts electrolysis to remove paint liquid residue and dirt from the inner wall of the mixing tank 2 and the surface of the equipment. The sensor 4502 at the bottom of the inner side of the mixing tank 2 monitors the temperature, liquid level and other parameters in real time during the cleaning process, and feeds back the data to ensure the cleaning effect, thus completing the entire constant temperature mixing and cleaning monitoring process of the electrophoretic paint liquid.

[0027] An input component 55 is fixedly connected to the top of the mixing tank 2. The input component 55 serves as the inlet for the paint liquid to enter the mixing tank 2, performing preliminary filtration and guidance on the incoming paint liquid. The input component 55 includes an inlet filter pipe 5501, which performs preliminary filtration on the incoming paint liquid, removing large particles and protecting downstream equipment. The bottom of the inlet filter pipe 5501 is fixedly connected to the top of the support plate 53. A first inlet connecting pipe 5502 is fixedly connected to the inner bottom of the inlet filter pipe 5501, connecting the inlet filter pipe 5501 to the inside of the mixing tank 2, ensuring smooth entry of the paint liquid into the mixing tank 2. A pulse flow inlet component 56 is fixedly connected to the top of the mixing tank 2. The pulse flow inlet component 56 uses a pulse control valve 5603 to achieve pulsed input of the paint liquid, increasing the mixing effect while reducing the shear force on the paint liquid. Component 56 includes a cross plate 5604, which is located at the top of the mixing tank 2 to ensure structural stability. The bottom of the cross plate 5604 is fixedly connected to the top of the mixing tank 2. A pulse control valve 5603 is fixedly connected inside the cross plate 5604. By controlling the pulse frequency and flow rate, the paint liquid is input in a pulse manner to increase the mixing effect. The output end of the pulse control valve 5603 is fixedly connected to a first connection inlet pipe 5601, and the outlet end of the pulse control valve 5603 is fixedly connected to a second connection inlet pipe 5602. A constant temperature box 7 is fixedly connected to the top of the supporting base plate 1 to provide a constant temperature environment for the entire device, ensuring that the paint liquid in the mixing tank 2 is mixed and filtered at a stable temperature. A control panel 8 is fixedly connected to the outside of the mixing tank 2. The control panel 8 serves as the operation and monitoring interface of the device, used to control functions such as heating, cleaning, and circulating filtration, and to display the equipment operating status in real time. Specifically, the paint solution is first pre-filtered through the inlet filter pipe 5501 of the input component 55, and then flows into the mixing tank 2 through the first inlet connection pipe 5502. At the same time, the pulse control valve 5603 of the pulse flow input component 56 controls the paint solution to be pulsedly input into the mixing tank 2 through the first connection inlet pipe 5601 and the second connection inlet pipe 5602 to improve the mixing effect. In the constant temperature environment created by the constant temperature chamber 7, the magnetic coupling pump 51 of the low shear mixing mechanism 5 and the bionic impeller 52 work together to mix the paint solution with low shear force. The coupling control column 41 in the heating mechanism 4 heats the paint solution at a constant temperature through the transmission line 42, the guide plate 43 and the inclined heating plate 44. The circulation filtration mechanism 6 operates synchronously to ensure the purity of the paint solution. After mixing is completed, the electrolyte plate 4501 of the cleaning component 45 starts electrolytic cleaning. The sensor 4502 monitors the cleaning parameters in real time. The operator monitors and adjusts each functional module through the control panel 8 to ensure the stable operation of the device.

[0028] Reference Figure 1 , Figure 2 and Figure 5The circulating filtration mechanism 6 includes a connecting support box 61, which serves as the main structure of the circulating filtration mechanism 6. The support box 61 has two internal filtration zones. The bottom of the connecting support box 61 is fixedly connected to the top of the supporting base plate 1. A dividing plate 62 is fixedly connected inside the connecting support box 61, dividing the internal space of the connecting support box into two zones. The left side of the dividing plate is used for filtering water, and the right side is used for filtering electrophoretic paint. First filter plates 63 are fixedly connected to both sides of the dividing plate 62, used for preliminary filtration of paint and cleaning large particles in the water. Second filter plates 64 are fixedly connected to the bottom of both sides of the dividing plate 62, used for further filtration of paint and cleaning fine particles in the water. A power assembly is fixedly connected to the left side of the second filter plate 64. 65. The power assembly 65 includes two extraction pumps 6501 and a dual-head pump 6503. The extraction pumps 6501 are used to extract the paint liquid in the mixing tank 2 and transport it to the circulation filtration mechanism 6. The external of the extraction pumps 6501 is fixedly connected to the left side of the inside of the connecting support box 61. The output end of the extraction pumps 6501 is fixedly connected to the second inlet connecting pipe 6502. The bottom of the dual-head pumps 6503 is fixedly connected to the top of the connecting support box 61. The output end of the dual-head pumps 6503 is fixedly connected to the connecting circulation pipe 6504. The dual-head pumps 6503 are used to transport the filtered paint liquid back to the mixing tank 2 to realize the circulation of the paint liquid. The right side of the connecting input pipe 54 is fixedly connected to the inside of the mixing tank 2. The right side of the first inlet connecting pipe 5502 is fixedly connected to the inside of the mixing tank 2. Specifically, after the paint liquid flows into the mixing tank 2 through the input component 55 and the pulse flow inlet component 56, the circulation filtration mechanism 6 is activated: the extraction pump 6501 pumps the paint liquid in the mixing tank 2 through the second inlet connecting pipe 6502 to the left filtration zone of the connecting support box 61. The paint liquid passes through the first filter plate 63 and the second filter plate 64 in sequence to remove large and small particles. The right filtration zone treats the cleaning water in the same way. The dual-head pump 6503 pumps the filtered paint liquid back to the mixing tank 2 through the connecting circulation pipe 6504 to form a circulation. During the mixing process, the magnetic coupling pump 51 and the bionic impeller 52 of the low-shear mixing mechanism 5 work continuously, and work with the coupling control column 41, the guide plate 43 and the inclined heating plate 44 of the heating mechanism 4 to achieve constant temperature mixing of the paint liquid. During cleaning, the electrolyte plate 4501 electrolyzes to remove residues, the sensor 4502 monitors parameters, the control panel 8 adjusts each component in real time, and the constant temperature box 7 maintains the overall ambient temperature to ensure stable operation of the entire process.

[0029] The implementation principle of this application embodiment is as follows: First, the coupling control column 41 is activated, and the signal is transmitted to the transmission line 42. The transmission line 42 then transmits the signal to the guide plate 43, which in turn transmits it to multiple inclined heating plates 44, thereby reducing the problem of uneven internal temperature flow. When the electrophoretic coating liquid enters through the inlet filter pipe 5501, it enters through the connecting input pipe 54, thereby activating the magnetic coupling pump 51. The magnetic coupling pump 51 itself has magnetic force, which drives the bionic impeller 52 to rotate. The top pulse control valve 5603 is used to control the pulse jet. The cross plate 5604 supports the pulse control valve 5603. Thus, when the low-shear mixing mechanism 5 is used, the mixing energy consumption is reduced while maintaining the stability of the paint liquid microstructure. The constant temperature box 7 maintains the internal constant temperature from the outside, effectively improving the stability of the system operation and the quality of the coating liquid, while reducing energy consumption and ensuring the stability of the paint liquid microstructure during the production process.

[0030] Secondly, after use, water is reintroduced into the mixing tank 2 through the inlet filter pipe 5501. The electrolyte plate 4501 is activated to clean the inside of the mixing tank 2. The cleaned water is then pumped through one of the extraction pumps 6501 and the second inlet connecting pipe 6502 to the left side of the connecting support box 61. The inside of the connecting support box 61 is divided into two areas by a partition plate 62. The other extraction pump 6501 and the second inlet connecting pipe 6502 are used to allow the electrophoretic paint solution to enter the right side of the partition plate 62. The cleaned water and the used electrophoretic paint solution are filtered through the first filter plate 63 and the second filter plate 64 and then pumped into the mixing tank 2 by the dual-head pump 6503 for reuse. This reduces the waste of water and electrophoretic paint solution, saves costs, and ensures the continuous use and cleanliness of the mixing tank 2.

Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
