Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, specifically to a high-efficiency electrophoresis drying chamber. Background Technology

[0002] In industries such as automobile manufacturing, machining, and home appliance production, electrophoretic coating is an important process for improving the corrosion resistance and aesthetics of metal workpieces. As a key piece of equipment for completing coating curing, the performance of the electrophoretic drying oven directly affects the coating quality and production efficiency.

[0003] A high-efficiency electrophoresis drying oven typically consists of an insulated chamber, a hot air circulation system, a heating device, a temperature control system, and an intelligent monitoring system. The insulated chamber uses a double-layer rock wool sandwich panel structure to effectively reduce heat loss. The hot air circulation system, through multiple axial flow fans and duct design, ensures uniform convection circulation of hot air within the drying oven. The heating device can use electric heating, natural gas heating, or steam heating to provide a stable heat source for the drying oven. The temperature control system uses high-precision temperature sensors and PID regulation technology to achieve precise temperature control within the drying oven. The intelligent monitoring system monitors the operating status of the drying oven in real time and automatically adjusts parameters.

[0004] However, in actual use, traditional electrophoretic drying ovens often use unidirectional airflow, resulting in uneven distribution of hot airflow within the oven. This leads to inconsistent heating of different parts of the workpiece, with areas near the air outlet being too hot and areas far from the air outlet being too cold. This can easily cause localized over-drying or insufficient drying of the paint film, affecting product quality. Therefore, we propose a high-efficiency electrophoretic drying oven.

[0005] The purpose of this invention is to provide a high-efficiency electrophoresis drying chamber to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency electrophoresis drying chamber includes a base, a slope plate fixedly installed on the base, a drying chamber body fixedly installed above the base, a door panel hinged to the drying chamber body, and a circulation assembly provided on the base. The circulation assembly includes:

[0008] An air outlet slot is provided on the base, a perforated floor is fixedly installed on the base, and air outlet holes are provided on the base. A top filter plate is fixedly installed inside the drying chamber body.

[0009] A heating device is fixedly installed on the drying chamber body, a mounting frame is fixedly installed on the top filter plate, a heat conduction pipe is fixedly installed on the mounting frame, and a mounting box is fixedly installed above the drying chamber body.

[0010] The mounting box contains a partition, a mounting rod is rotatably mounted on the partition, a turbine is fixedly mounted on the mounting rod, and a fan is fixedly mounted on the mounting box.

[0011] In a further embodiment, the perforated floor has an air outlet, and multiple sets of mounting brackets, mounting rods, turbines, and fans are provided. The heating device is connected to a heat pipe.

[0012] In a further embodiment, the mounting bracket, heat pipe, mounting box, partition, mounting rod, turbine, and fan are positioned above the top filter plate.

[0013] In a further embodiment, the multiple sets of mounting rods, turbines, and fans are divided into two modules, with the fans in the two modules having opposite airflow directions and the turbines having opposite arc directions.

[0014] In a further embodiment, the mounting box is provided with an auxiliary component, which includes a square tube. The square tube is fixedly installed on the partition. A motor is fixedly installed on the mounting box. One end of a round rod is fixedly installed at the output end of the motor, and a fan is fixedly installed at the other end of the round rod.

[0016] In a further embodiment, the round rod is disposed inside the square tube, and the fan is disposed below the heat pipe.

[0017] Compared with the prior art, this utility model provides a high-efficiency electrophoresis drying chamber, which has the following features:

[0018] Beneficial effects:

[0019] 1. This high-efficiency electrophoretic drying oven, to ensure consistent drying of the electrophoretic coating film, is equipped with a circulation component. This component, in conjunction with a heating device, heats the air through heat pipes. Multiple sets of fans drive the airflow in opposite directions through turbines, forming bidirectional convection above the top filter plate: one set of fans pushes the hot airflow to the left along the top of the drying oven, while the other set pushes it to the right, allowing the hot airflow to cover the entire width of the drying oven. At the same time, the rotation of the turbines further cuts the airflow, forming numerous small vortices. Combined with the uniform air distribution effect of the top filter plate, the hot airflow is evenly blown onto the workpiece surface through the air outlets of the perforated floor. Meanwhile, the design of the air outlet slots and air outlets forms an airflow loop, allowing the hot air to circulate within the drying oven and ensuring consistent drying of the electrophoretic coating film.

[0020] 2. To improve the overall production efficiency of this high-efficiency electrophoresis drying chamber, an auxiliary component is installed. This component works with a motor to drive a round rod to rotate at high speed inside a square cylinder, which in turn drives a fan to create a strong downward airflow below the heat pipe. This airflow forcefully washes the surface of the heat pipe, breaks down the boundary layer thermal resistance, and improves the heat dissipation efficiency of the heat pipe into the drying chamber. The fan's position design ensures that the strong airflow acts directly on the space above the workpiece, forming an orthogonal mixture with the horizontal airflow of the circulation component, further enhancing the turbulence of the hot airflow and further improving the heating uniformity of different parts of the workpiece.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation.

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0034] Please see Figures 1-7 This utility model provides a technical solution:

[0035] A high-efficiency electrophoresis drying chamber includes a base 1, a slope plate 2 fixedly installed on the base 1, a drying chamber body 3 fixedly installed above the base 1, and a door panel 4 hingedly installed on the drying chamber body 3.

[0036] In one embodiment of this utility model, a circulation component 5 is provided on the base 1, the circulation component 5 includes an air outlet slot 51, the base 1 has an air outlet slot 51, a perforated floor 52 is fixedly installed on the base 1, and an air outlet 53 is provided on the base 1. A top filter plate 54 is fixedly installed inside the drying chamber body 3, a heating device 55 is fixedly installed on the drying chamber body 3, a mounting bracket 56 is fixedly installed on the top filter plate 54, a heat conduction pipe 57 is fixedly installed on the mounting bracket 56, an installation box 58 is fixedly installed above the drying chamber body 3, a partition 59 is fixedly installed inside the installation box 58, and an installation rod 51 is rotatably installed on the partition 59. 0. A turbine 511 is fixedly installed on the mounting rod 510, and a fan 512 is fixedly installed on the mounting box 58. An air outlet is opened on the perforated floor 52. Multiple sets of mounting brackets 56, mounting rods 510, turbines 511 and fans 512 are provided. The heating device 55 is connected to the heat conduction pipe 57. The mounting brackets 56, heat conduction pipe 57, mounting box 58, partition 59, mounting rods 510, turbines 511 and fans 512 are arranged above the top filter plate 54. The multiple sets of mounting rods 510, turbines 511 and fans 512 are divided into two modules. The fans 512 in the two modules have opposite airflow directions, and the turbines 511 have opposite arc directions.

[0037] In this embodiment, when the electrophoretic workpiece is placed into the drying chamber body 3 and the door panel 4 is closed, the circulation component 5 starts first, and the heating device 55 starts working. Connected to the heat conduction pipe 57, it transfers heat to the heat conduction pipe 57. Multiple sets of fans 512 operate synchronously. Since they are divided into two modules with opposite airflow directions, one set of fans 512 pushes the hot airflow to the left along the top of the drying chamber, while the other set pushes it to the right, forming a horizontal bidirectional convection. During the flow of the hot airflow, it passes through the turbine 511. The turbine 511 is impacted and rotated by the airflow, further cutting the airflow and breaking the large stream of hot airflow into countless small vortices. The top filter plate 54 plays a role in evenly distributing the hot airflow, making the airflow distribution more balanced, so that it is evenly blown onto the surface of the workpiece to heat and dry the electrophoretic paint film. At the same time, the hot airflow enters the air outlet slot 51 and the air outlet hole 53 through the air outlet of the perforated floor 52 and is discharged from the drying chamber body 3 to achieve hot air discharge, ensure that the temperature field inside the drying chamber is uniform, and ensure that the drying effect of the electrophoretic paint film is consistent.

[0038] In one embodiment of this utility model, an auxiliary component 6 is provided on the mounting box 58. The auxiliary component 6 includes a square tube 61. The square tube 61 is fixedly installed on the partition plate 59. The motor 62 is fixedly installed on the mounting box 58. One end of the round rod 63 is fixedly installed at the output end of the motor 62. The other end of the round rod 63 is fixedly installed with a fan 64. The square tube 61, the motor 62, the round rod 63 and the fan 64 are arranged above the top filter plate 54. The round rod 63 is arranged inside the square tube 61 and the fan 64 is arranged below the heat conduction pipe 57.

[0039] In this embodiment, the motor 62 is powered on simultaneously, and its output drives the round rod 63 to rotate at high speed inside the square tube 61. The round rod 63 drives the fan 64 to rotate, forming a strong vertical downward airflow below the heat pipe 57. This strong airflow forcibly washes the surface of the heat pipe 57, breaking the boundary layer thermal resistance on the surface of the heat pipe 57, accelerating the transfer of heat from the heat pipe 57 to the air in the drying chamber, and greatly improving the heat dissipation efficiency of the heat pipe 57. The vertical airflow generated by the fan 64 is orthogonally mixed with the horizontal airflow formed by the circulation component 5, further increasing the turbulence of the hot airflow. The increased turbulence allows the hot airflow to fully contact the surface of the workpiece, promoting heat exchange, ensuring that the heating uniformity of different parts of the workpiece is further improved, shortening the drying time, and improving the overall production efficiency.

[0040] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the heating device 55, the fan 512, and the motor 62. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
