Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a low-temperature drying device for metal surface treatment. Background Technology
[0002] Low-temperature metal drying refers to drying metal at a relatively low temperature, typically around 70°C. The drying time depends on the size and shape of the metal, generally ranging from 20 minutes to 1 hour. The main purpose of low-temperature drying is to remove moisture and oil from the metal surface, and it is commonly used for metal treatment before surface coating. This drying method keeps the metal surface dry and clean, thereby improving coating quality and extending the coating's lifespan.
[0003] Currently, when drying metal parts at low temperatures, the parts are usually placed directly inside the oven, and the operator sets the drying time based on experience. However, this is not accurate enough; too long a time wastes resources, while too short a time fails to achieve the desired drying effect. Furthermore, current drying methods place the metal parts near the heat source, resulting in uneven heating due to varying distances. This leads to localized overheating and structural changes on the metal surface, altering the original mechanical properties of the metal parts. Utility Model Content

[0021] Reference Figure 1-3 A low-temperature drying device for metal surface treatment includes: a cylindrical base 1, with mounting holes on two side walls of the cylindrical base 1, a clamping structure installed in the two mounting holes of the cylindrical base 1, a top cover structure installed on the upper wall of the cylindrical base 1, a support structure installed on the lower wall of the cylindrical base 1, a power structure installed on the upper wall of the support structure, and several heaters 15 installed on the inner side of the cylindrical base 1; the clamping structure includes: a clamping seat 2, two screws 3, and two clamping plates 4; the clamping seat 2 is installed in the mounting holes of the cylindrical base 1 through bearings, the two screws 3 are respectively installed inside the clamping seat 2 through threads, and the two clamping plates 4 are respectively installed inside the screws 3 through turntables.
[0022] Specifically, the upper cover structure includes: two hinges 5 and a drying upper cover 6; the drying upper cover 6 is installed on the upper wall of the cylindrical base 1 through the two hinges 5, a humidity sensor 14 is installed on the upper wall of the drying upper cover 6, and the upper cover of the drying upper cover 6 has several ventilation holes.
[0023] Specifically, the support structure includes: four support frames 7, a heat-insulating base 8, and four support legs 9; the four support frames 7 are respectively installed on the lower wall of the cylindrical base 1, the heat-insulating base 8 is installed on the lower wall of the four support frames 7, and the four support legs 9 are installed on the lower wall of the heat-insulating base 8.
[0024] Specifically, the power structure includes: a power motor 10, a drive wheel 11, a driven wheel 12, and a transmission belt 13; the power motor 10 is mounted on the upper wall of the heat-insulating chassis 8, the drive wheel 11 is mounted on the drive end of the power motor 10, the driven wheel 12 is mounted on the side wall of the clamping seat 2, and the transmission belt 13 is fitted around the drive wheel 11 and the driven wheel 12.
[0025] Working Principle: Before using this utility model, the operator needs to connect an external AC power supply to provide power to the electrical appliance. The operator first opens the drying cover 6 using the two hinges 5. Then, the operator rotates the two screws 3 to separate the two clamping plates 4. Next, the operator places the metal part to be dried on the upper wall of the clamping seat 2. Then, the operator rotates the two screws 3 to move the two clamping plates 4 closer to the metal part until the two clamping plates 4 fix the metal part in place. The inner sides of the two clamping plates 4 are equipped with high-temperature resistant rubber pads to increase the friction between the clamping plates 4 and the metal part. After applying friction, the operator resets the drying cover 6 and starts the heater 15. The hot air passes through the metal parts and heats them at a low temperature. At this time, the moisture on the metal parts evaporates continuously and escapes through the vents of the drying cover 6. The humidity sensor 14 records the humidity of the air passing through the vents. When the humidity is zero, the metal parts are dried. At the same time, the power motor 10 drives the drive wheel 11 to rotate, and drives the driven wheel 12 to rotate through the transmission belt 13. The driven wheel 12 drives the clamping seat 2 to rotate in a circle, which in turn drives the metal parts to rotate, so that the metal parts can be heated at a low temperature evenly.
