Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying device for electrophoretic processing. Background Technology

[0002] Electrophoretic coating is a process that uses an electric field to cause charged particles to migrate in a liquid medium and form a uniform coating on the surface of a workpiece. It is widely used in metal surface treatment, automobile manufacturing, and home appliance production. Its main advantages include uniform coating, strong adhesion, good corrosion resistance, and environmental protection and energy saving. By setting an anode and a cathode in the electrophoresis tank, with the workpiece as the anode or cathode, under the action of an electric field, charged coating particles migrate to the workpiece and deposit on the workpiece surface to form a coating. After drying and curing, a dense, smooth, and uniform protective layer is formed, which effectively improves the corrosion resistance and aesthetics of the workpiece.

[0003] CN217979682U discloses a drying device for electrophoretic processing of automotive parts. When drying automotive parts, a sliding plate is first pulled out, then a support plate is placed in a groove. The sliding plate is then released, and a spring returns it to its original position, causing a limiting rod at one end of the sliding plate to insert into a limiting groove in the support plate, thus fixing the support plate in place. The dryer body is then started, and the automotive parts are placed on a conveyor belt, which transports them into the dryer body for drying. After drying, the conveyor belt is started again to transport the automotive parts out. During drying, dirt on the surface of the automotive parts may be dried onto the conveyor belt. The surface of the conveyor belt can be cleaned using brushes and scrapers located at the bottom of the support plate at one end of the dryer body. This prevents dirt that is difficult to clean from the automotive parts from falling onto the conveyor belt, being dried by the dryer body, and sticking to the conveyor belt surface. Over time, this would require manual cleaning by stopping the machine and using brushes, reducing work efficiency.

[0004] The electrophoretic drying device for automotive parts uses brushes and scrapers at the bottom of the support plate to clean the surface of the conveyor belt. However, during the drying process, a large amount of hot air is discharged from both sides of the dryer body, resulting in a significant waste of heat. Furthermore, it is inconvenient to dry the bottom of the parts on the conveyor belt, affecting the drying effect and efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a drying device for electrophoretic processing.

[0006] This utility model is achieved by the following technical solution: a drying device for electrophoretic processing, including a frame, a dryer body is fixedly installed on the top of the frame, a conveyor belt is provided inside the frame, a number of through holes are opened on the inner wall of the conveyor belt at equal intervals, and heat recovery components are provided at both ends of the frame.

[0007] The heat recovery assembly includes an installation box, a bracket fixedly connected to the inner wall of the installation box, a negative pressure fan fixedly connected to the bottom of the bracket, a fixed pipe connected to the top of the installation box, air collecting hoods connected to both the left and right ends of the fixed pipe, a diversion pipe connected to the inner wall of the air collecting hood, an air supply pipe connected to the bottom of the installation box, an air outlet pipe connected to one bottom end of the air supply pipe, and a connecting pipe connected to the inner wall of the air outlet pipe.

[0008] The above technical solution uses a negative pressure fan to create negative pressure inside the fixed pipe and the air collection hood, drawing hot air from both sides of the dryer body into the mounting box. The hot air is then sent into the air outlet pipe through the air supply pipe and blown upwards through the air outlet pipe. Through the through holes on the conveyor belt, the hot air can dry the bottom of the parts, improving drying efficiency and effect. By collecting and reusing the hot air generated during the operation of the dryer body, energy consumption is reduced, thereby lowering production costs.

[0009] As a further improvement to the above solution, the front end of the mounting box is fixedly connected to the rear end of the frame.

[0010] As a further improvement to the above solution, the surface of the air collecting hood is fixedly connected to the inner wall of the dryer body.

[0011] With the above technical solution, the two air collection hoods are located at the openings on both sides of the dryer body.

[0012] As a further improvement to the above scheme, the end of the diversion pipe away from the air collecting hood is connected to the fixed pipe.

[0013] The above technical solution increases the negative pressure range of the air collection hood by using a diversion pipe, thereby improving the heat recovery efficiency.

[0014] As a further improvement to the above solution, the two ends of the air outlet pipe are fixedly connected to the inner wall of the frame, and the air outlet pipe is located inside the conveyor belt.

[0015] With the above technical solution, since the air outlet pipe is located inside the conveyor belt, hot air is discharged upwards to dry the bottom of the parts.

[0016] As a further improvement to the above solution, the top of the air outlet pipe is provided with several air outlet holes that are evenly distributed.

[0017] The above technical solution ensures that hot air can be blown evenly onto the surface of the parts through several air outlets, avoiding problems such as local overheating or uneven heating.

[0018] As a further improvement to the above solution, the number of air outlet pipes is set to several, and the several air outlet pipes are interconnected by connecting pipes.

[0019] The above technical solution connects several air outlet pipes through connecting pipes, allowing hot air to be blown out from different positions, thus improving the drying effect on the parts.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention utilizes a heat recovery component, specifically a negative pressure fan to create negative pressure inside the fixed pipe and the air collecting hood. This draws hot air from both sides of the dryer body into the mounting box, then into the air outlet pipe via the air supply pipe. Finally, the hot air is blown upwards through the air outlet pipe and through the through holes in the conveyor belt, allowing the hot air to dry the bottom of the parts, thus improving drying efficiency and effectiveness.

[0022] This invention reduces energy consumption and thus lowers production costs by incorporating a heat recovery component, specifically by collecting and reusing the hot air generated during the operation of the dryer. Attached Figure Description

[0033] The heat recovery assembly 5 includes a mounting box 501. A bracket 502 is fixedly connected to the inner wall of the mounting box 501. A negative pressure fan 503 is fixedly connected to the bottom of the bracket 502. A fixed pipe 504 is connected to the top of the mounting box 501. Both ends of the fixed pipe 504 are connected to air collecting hoods 505. A diversion pipe 506 is connected to the inner wall of the air collecting hood 505. An air supply pipe 507 is connected to the bottom of the mounting box 501. An air outlet pipe 508 is connected to one end of the bottom of the air supply pipe 507. A connecting pipe 509 is connected to the inner wall of the air outlet pipe 508. The parts are conveyed to the interior of the dryer body 2 via a conveyor belt 3 for drying. During the drying process, the frame 1... The internal hot air is discharged outward through the openings on both sides. At this time, the negative pressure fan 503 is started. The negative pressure fan 503 creates negative pressure inside the fixed pipe 504 and the air collection hood 505, drawing the hot air from both sides of the dryer body 2 into the mounting box 501. Then, it is sent into the air outlet pipe 508 through the air supply pipe 507, and then blown upward through the air outlet pipe 508. Through the through holes 4 on the conveyor belt 3, the hot air can dry the bottom of the parts, improving the drying efficiency and effect. By collecting the hot air generated during the operation of the dryer body 2 and reusing it, energy consumption is reduced, thereby reducing production costs.

[0034] The front end of the mounting box 501 is fixedly connected to the rear end of the rack 1.

[0035] The surface of the air collecting hood 505 is fixedly connected to the inner wall of the dryer body 2.

[0036] The end of the diversion pipe 506 away from the air collecting hood 505 is connected to the fixed pipe 504. The diversion pipe 506 increases the negative pressure range of the air collecting hood 505 and improves the hot air recovery efficiency.

[0037] The two ends of the air outlet pipe 508 are fixedly connected to the inner wall of the frame 1. The air outlet pipe 508 is located inside the conveyor belt 3. Because the air outlet pipe 508 is located inside the conveyor belt 3, hot air is discharged upwards to dry the bottom of the parts above the conveyor belt 3.

[0038] The top of the air outlet duct 508 has several air outlet holes that are evenly distributed. These air outlet holes allow hot air to be discharged from different locations to dry different parts of the component.

[0039] There are several air outlet ducts 508, and the several air outlet ducts 508 are interconnected by connecting pipes 509.

[0040] The implementation principle of the drying device for electrophoresis processing in this embodiment is as follows: During use, the electrophoretically treated parts are placed on the conveyor belt 3, and the parts are transported to the interior of the dryer body 2 by the conveyor belt 3 for drying. During the drying process, the hot air inside the frame 1 is discharged outward through the openings on both sides. At this time, the negative pressure fan 503 is started, and the negative pressure fan 503 generates negative pressure inside the fixed pipe 504 and the air collecting hood 505, which draws the hot air from both sides of the dryer body 2 into the mounting box 501, and then sends it into the air outlet pipe 508 through the air supply pipe 507. Then, the hot air is blown upward through the air outlet pipe 508. Through the through holes 4 opened on the conveyor belt 3, the hot air can dry the bottom of the parts, which improves the drying efficiency and effect. By collecting the hot air generated during the operation of the dryer body 2 and reusing it, energy consumption is reduced, thereby reducing production costs.
