Description

Technical Field

[0001] The utility model relates to a drying device for zinc-aluminum-magnesium steel coils, belonging to the technical field of workshop drying equipment. Background Technique

[0002] In recent years, the development and application of zinc-aluminum-magnesium coating materials have been highly regarded by countries around the world. Their composition systems and application scopes have been continuously developed. In 1985, the Japan Iron and Steel Research Center first developed Zn-4.5%Al-0.1%Mg coated steel plates. Major domestic steel mills have also independently developed zinc-aluminum-magnesium coils with their own composition systems, which are respectively applied to fields such as automobiles, household appliances, and construction according to different base materials and coating compositions. With the wide application of zinc-aluminum-magnesium coating materials, in order to ensure that the product performance is not affected during use, the following aspects need to be particularly noted during storage: 1. Dry and ventilated: The warehouse storing zinc-aluminum-magnesium coils should be kept dry, and the relative humidity is preferably controlled below 60%. Good ventilation conditions help to disperse moisture and reduce the possibility of rust on the surface of the coils. For example, installing ventilation fans or ventilation ducts in the warehouse can effectively promote air circulation; 2. Appropriate temperature: Avoid storing the coils in an environment with too high or too low temperature. Extreme temperatures may affect the physical properties and coating quality of the coils. Generally, the appropriate storage temperature is between 5°C and 35°C.

[0025] Embodiment 1

[0026] At present, in order to prevent the zinc-aluminum-magnesium steel coil from rusting due to moisture or being affected by too cold or too hot temperature when stored in the workshop or warehouse, it is necessary to use a fan or a hot air blower to blow air and exchange heat on the surface of the zinc-aluminum-magnesium steel coil for drying. In the prior art, usually one fan or hot air blower is used for a whole row of zinc-aluminum-magnesium steel coils. Since the number of steel coils is large, the number of fans or hot air blowers required is also large, which virtually brings a lot of costs to the enterprise.

[0027] As Figures 1-3 shown, a drying device for zinc-aluminum-magnesium steel coils includes a guide rail 1 and a proximity switch 5 fixedly installed on the ground of the workshop or warehouse where the zinc-aluminum-magnesium steel coils are stored. A transport vehicle 2 is movably connected to the top of the guide rail 1. The proximity switch 5 receives the position signal of the transport vehicle 2 and controls the transport vehicle 2 to reciprocate along the direction parallel to the guide rail 1 on the top of the guide rail 1. A heat exchange device 3 is installed on the top of the transport vehicle. The heat exchange device 3 is used to blow air and exchange heat on the zinc-aluminum-magnesium steel coils, so as to dry the zinc-aluminum-magnesium steel coils.

[0028] In some alternative embodiments, the heat exchange device 3 can be set as a fan or a hot air blower according to the actual temperature. Specifically, when the weather is relatively cold, a hot air blower is selected, such as a diesel hot air blower or an electric hot air blower. When the weather is hot or the room temperature is greater than 5 degrees Celsius, a fan is selected. According to the actual needs, cold air or hot air is blown to dehumidify and dry the surface of the zinc-aluminum-magnesium steel coils. When the weather is relatively hot, the surface of the zinc-aluminum-magnesium steel coils is cooled by the fan. When the weather is relatively cold, while selecting the hot air blower for drying, the temperature of the surface of the zinc-aluminum-magnesium steel coils is increased to avoid the influence of extreme temperatures on the physical properties and coating quality of the zinc-aluminum-magnesium steel coils.

[0029] In some alternative embodiments, the transport vehicle 2 is composed of a flat plate 10, a drive motor 11, a driving wheel 8, a driven wheel 9 and a transmission mechanism. The driving wheel 8 and the driven wheel 9 are both rotatably connected to the bottom of the flat plate 10. The heat exchange device 3 and the drive motor 11 are both installed on the top of the flat plate 10.

[0030] Specifically, the transmission mechanism is composed of a driving transmission wheel 12, a driven transmission wheel 13 and a transmission connecting piece 14. The driving transmission wheel 12 is fixedly connected to the output end of the drive motor 11. The driving transmission wheel 12 is connected to the driven transmission wheel 13 through the transmission connecting piece 14. The driving wheels 8 are connected by a transmission shaft 15, and the driven transmission wheel 13 is installed on the transmission shaft 15.

[0031] Preferably, the transmission mechanism drives the transport vehicle 2 in a belt drive manner. The driving transmission wheel 12 and the driven transmission wheel 13 are both set as belt wheels, and the transmission connecting piece 14 is set as a belt.

[0032] Preferably, the transmission mechanism drives the transport vehicle 2 by means of a chain drive. The driving sprocket 12 and the driven sprocket 13 are both set as sprockets, and the transmission connecting member 14 is set as a chain.

[0033] In some alternative embodiments, support rods 4 are fixedly connected to both ends of the guide rail 1. A steel wire rope 6 for supporting the wire is fixedly connected between the support rods 4. A spiral wire 7 is threaded through the steel wire rope 6. One end of the spiral wire 7 is electrically connected to the drive motor 11, and the other end of the spiral wire 7 is connected to the mains power. For fans and electric heaters that require mains power supply, power supply is also carried out through the spiral wire 7 at the same time.

[0034] In some alternative embodiments, two proximity switches 5 are provided and are respectively installed at the left and right ends of the guide rail 1. When the transport vehicle approaches the proximity switch 5, the proximity switch 5 receives the signal and controls the drive motor 11 to reverse, and the transport vehicle moves in the reverse direction to achieve reciprocating motion on the guide rail 1. The wiring and control method of the proximity switch 5 and the drive motor 11 are both prior arts and will not be elaborated here.

[0035] Embodiment 2

[0036] As Figure 4 shown, in some alternative embodiments, the proximity switch 5 is installed on the flat plate 10. A battery 16 is also installed on the top of the flat plate 10. The battery 16 is electrically connected to the drive motor 11. The battery 16 can use common rechargeable batteries on the market, such as storage batteries, etc. The battery 16 can also be connected to the heat exchange device 3 for power supply at the same time. The overall mechanism is powered by the battery 16, saving the wire length of the wire and effectively reducing the cost.

[0037] More specifically, metal rods 17 that cooperate with the proximity switch 5 are fixedly installed at both the left and right ends of the guide rail 1. When the proximity switch 5 on the top of the flat plate 5 approaches the metal rod 17, the proximity switch 5 receives the signal and controls the drive motor 11 to reverse, and the transport vehicle moves in the reverse direction to achieve reciprocating motion on the guide rail 1.

[0038] In addition, the proximity switch 5 can also be replaced with a signal isolation grid or the like with a similar function in the prior art.

[0039] Working principle of the utility model: The driving motor 11 drives the driving wheel 8 to rotate, and then drives the driven wheel 9 to rotate synchronously to realize the movement of the transport vehicle 2 on the guide rail 1. The proximity switch 5 receives the position signal of the transport vehicle 2 and controls the transport vehicle 2 to reciprocate on the top of the guide rail 1 in a direction parallel to the guide rail 1. A heat exchange device 3 is installed on the top of the transport vehicle 2. The heat exchange device 3 is used for blowing and heat exchanging the zinc-aluminum-magnesium steel coil, so as to dry the zinc-aluminum-magnesium steel coil. During the reciprocating movement of the transport vehicle 2, heat exchange and drying are carried out on the zinc-aluminum-magnesium steel coils stored in multiple rows, thus realizing the replacement of multiple traditional fixed fans or hot air blowers with a single heat exchange device 3, effectively reducing costs.
