Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing technology, specifically to a drain rack for hot-dip galvanized sheet metal. Background Technology

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, is an effective method of metal corrosion protection, mainly used in metal structures across various industries. It involves immersing rust-removed steel components in molten zinc at approximately 500°C, causing a zinc layer to adhere to the surface of the steel components, thus achieving corrosion protection.

[0003] After the sheet metal is passivated with passivating solution, the passivating solution adhering to the surface of the sheet metal needs to be blown off and the hot-dip galvanized sheet metal needs to be drained before subsequent painting work can be carried out. In the existing technology, the hot-dip galvanized sheet metal is mostly drained by placing the hot-dip galvanized sheet metal on a draining rack and letting the passivating solution on the surface of the sheet metal be blown off by natural wind. However, this method of blowing off the passivating solution on the surface of the sheet metal is not only time-consuming, but also inefficient. Therefore, we propose a draining rack for hot-dip galvanized sheet metal. Utility Model Content

Gear rings 11, gears 12, etc. are used to realize the rotation of hot-dip galvanized sheets. Slide grooves 13, placement seats 15, etc. are used to clamp and place hot-dip galvanized sheets of different specifications.

[0030] The air drying mechanism is installed on the housing 1. The air drying mechanism includes a hot air blower 17, an air outlet, and two openings. The hot air blower 17 is installed on the housing 1, and the air outlet and two openings are also located on the housing 1. The air outlet of the hot air blower 17 is connected to an air supply pipe, and both ends of the air supply pipe are connected to air supply hoppers 18. A blower hood 19 is fixedly connected inside the openings. The blower hood 19 is connected to the air supply hoppers 18. The hot air blower 17 is used to blow out hot air, and the air supply pipe, blower hood 19, etc. are used to transport air to accelerate the drying of hot-dip galvanized sheets and improve efficiency.

[0031] A guide plate 20 is fixedly connected inside the box 1, and a drain pipe 21 is connected to the box 1. A valve is installed on the drain pipe 21 to facilitate the discharge of dripping passivation liquid.

[0032] Dustproof nets 22 are fixedly connected to both the air outlet and the blower cover 19 to block dust.

[0033] A double door 23 is rotatably connected to the box 1. The double door 23 is made of transparent material and is used to close or open the box 1 to facilitate viewing the internal situation.

[0034] A fixed post 24 is fixedly connected to the guide plate 20, and the other end of the rotating shaft is rotatably connected to the fixed post 24 to improve the stability of the rotating shaft and gear 5.

[0035] A support block 25 is fixedly connected inside the slide groove 13, and a bidirectional screw is rotatably connected to the support block 25 through it for limiting and improving the stability of the bidirectional screw.

[0036] It should be further explained that the motor 4 and hot air blower 17 in this embodiment are conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method and electrical connection method can be easily explained by those skilled in the art by following the instructions for use.

The installation position of the control switches can be selected according to actual usage needs to facilitate operation and control by the operator.

[0037] In summary, the working principle and process of this hot-dip galvanized sheet drying rack are as follows: First, place the rack at the desired location. Then, when using it, open the double-leaf door 23, place the hot-dip galvanized sheet between the two sliding grooves 13, and rotate the double-sided screw. The screw drives the two sliders 14 to move, and the sliders 14 drive the placement seats 15 to move, allowing the two placement seats 15 to clamp the hot-dip galvanized sheet. If the hot-dip galvanized sheet is short, loosen the tightening bolt 8, adjust the position of the fixing rod 7 and the sliding groove 13 on the fixing rod 7, and tighten the tightening bolt 8 after adjustment. In this way, the hot-dip galvanized sheet can be fixed by the four placement seats 15. When motor 4 is started, it drives the rotating shaft and gear 5 to rotate. Gear 5 drives gear ring 10, rotating seat 9, and hot-dip galvanized sheet to rotate. At this time, gear 12 and power shaft also move with rotating seat 9. Gear 12 meshes with gear ring 11, and gear 12 drives the power shaft to rotate, which facilitates the cooperation of slide 13, placement seat 15, etc., and drives the hot-dip galvanized sheet to rotate. In this way, when multiple hot-dip galvanized sheets rotate together, each hot-dip galvanized sheet can also rotate on its own, which facilitates the rotation and speeds up the dripping and drying of passivation liquid. It is also convenient to cooperate with the hot air blown out by hot air blower 17, blower hood 19, etc. for further drying, thus improving efficiency.

[0038] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
