Description

Technical Field

[0001] This utility model relates to the field of metal drying technology, specifically a drying device for metal surface treatment. Background Technology

[0002] Metals generally refer to a class of substances that have a unique luster but are opaque, ductile, and have thermal and electrical conductivity. For metal castings, the surface treatment methods we commonly use are mechanical grinding, chemical treatment, surface heat treatment, and surface spraying. When performing these surface treatments, the metal usually needs to be dried first.

[0003] According to announcement number CN219797708U, a metal surface drying oven includes a box body, with inlet and outlet mechanisms provided on the left and right end surfaces of the box body, and rails connected to the inner walls of the front and rear end of the box body. Connecting plates are inserted inside the rails, and the left and right ends of the connecting plates extend through the outside of the box body.

[0004] Regarding the above description, the applicant believes the following issues exist: During use, when drying metal products, the device typically requires placing them in a drying oven and using a heating plate for drying. However, only the side of the metal product facing the heating plate can be dried, while the other side may retain moisture due to insufficient heating. In this case, manual assistance is required to turn the product over. At this time, the drying oven is still in a high-temperature environment. When operators reach into the oven to turn the product over, they are prone to burns due to contact with high-temperature components or hot airflow, posing a safety hazard. Utility Model Content

[0016] Compared with the prior art, the present invention provides a drying device for metal surface treatment, which has the following advantages: 1. This drying device for metal surface treatment, through an auxiliary mechanism, is activated by an electric push rod, which pushes the insert rod into the insertion slot of the long rod, fixing the long rod in the long slot of the top filter plate. This firmly clamps the metal product between the top and bottom filter plates, preventing the product from shaking due to airflow impact. Turning the handle drives the rotating rod, and the annular slide slides along the annular groove, adjusting the angle between the bottom and top filter plates to ensure that the surface of the metal product is fully exposed to the drying airflow. The moving seat drives the T-shaped block to move along the T-slot, allowing the insert block to be inserted into the corresponding slot, achieving angle locking and preventing positional deviation during drying.

[0017] 2. This drying device for metal surface treatment uses a blower mechanism. When the motor starts, it drives the worm gear to rotate. The worm gear meshes with the worm wheel to drive the rotating shaft to rotate, which in turn drives the fan blades to rotate and generate airflow. The airflow enters the drying chamber through the filter holes of the top and bottom filter plates. As it flows over the surface of the metal products, it carries away the moisture. At the same time, the hollow structure of the filter plates allows the airflow to circulate, avoids local airflow stagnation, ensures that all areas of the metal surface are heated evenly, and improves drying efficiency.

Example

[0025] See Figure 1-7 Furthermore, based on Embodiment 1, the blower mechanism 5 further includes a motor 51, which is fixedly connected to the lower front end of the drying chamber 1. A worm gear 53 is fixedly connected to the back of the motor 51. Worm wheels 55 are meshed with the front and rear surfaces of the worm gear 53. A rotating shaft 54 ​​is fixedly connected to the shaft center of the worm wheel 55. The surface of the rotating shaft 54 ​​is rotatably connected to the bottom of the drying chamber 1. A fan blade 52 is fixedly connected to the upper surface of the rotating shaft 54. There are two worm gears 53, and the surfaces of the two worm gears 53 are rotatably connected to the inside of the drying chamber 1. The thread specifications of the front and rear surfaces of the worm gears 53 are the same and the direction is the same.

[0026] Furthermore, the worm gear meshing with the worm wheel 55 drives the rotating shaft 54 ​​to rotate, which in turn drives the fan blade 52 to rotate and generate airflow. The airflow enters the drying chamber 1 through the filter holes of the top filter plate 3 and the bottom filter plate 4, and carries away moisture as it flows over the surface of the metal products. At the same time, the hollow structure of the filter plate allows airflow to circulate, avoids local airflow stagnation, ensures that all areas of the metal surface are heated evenly, and improves drying efficiency.

[0027] In actual operation, when this device is in use, the metal product is placed between the top filter plate 3 and the bottom filter plate 4, and is stably fixed and its position adjusted by the auxiliary mechanism 2. Push the top filter plate 3 to slide on the surface of the T-shaped support rod 227 until the top filter plate 3 presses against the metal product. At this time, the electric push rod 225 is activated, pushing the insertion rod 222 to insert into the insertion slot 221 of the long rod 223, so that the long rod 223 is fixed in the long slot 224 of the top filter plate 3, so that the metal product is firmly clamped between the top filter plate 3 and the bottom filter plate 4, preventing the product from shaking due to airflow impact. Rotating the handle 213 causes the rotating rod 211 and the cross connecting plate 212 to rotate. The annular slide plate 214 slides along the annular groove 215, which can adjust the angle between the bottom filter plate 4 and the top filter plate 3, ensuring that the surface of the metal product is fully exposed to the drying airflow. Under the elastic force of the spring 2102, the moving seat 2105 drives the T-block 2106 to move along the T-slot 217, so that the insert block 2104 is inserted into the corresponding slot 216. The screw 2101 fixes the connecting seat 219 and the cross connecting plate 212 with threads to lock the angle and prevent the position from shifting during drying. The motor 51 starts and drives the worm gear 53 to rotate. The worm gear meshes with the worm wheel 55 and drives the rotating shaft 54 ​​to rotate, which in turn drives the fan blades 52 to rotate and generate airflow. The airflow enters the drying chamber 1 through the filter holes of the top filter plate 3 and the bottom filter plate 4. When it flows over the surface of the metal product, it carries away the moisture. At the same time, the hollow structure of the filter plate allows the airflow to circulate, avoids local airflow stagnation, ensures that all areas of the metal surface are heated evenly, and improves the drying efficiency.
