Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel component processing technology, and in particular to a coating and drying equipment for bridge steel structural components. Background Technology
[0002] As the core supporting structure of modern bridges, bridge steel structural components are exposed to complex environments for a long time. Their anti-corrosion coating process directly affects the service life and safety of the bridge. After the steel components are sprayed, they usually need to be dried in order to improve efficiency.
[0003] In the existing technology, traditional drying equipment has significant drawbacks in use. For example, in the use of traditional drying ovens, the workpiece is placed in the drying oven and then heated by an electric heating plate to achieve the drying effect. However, the high-temperature gas generated after drying is directly discharged, which can easily cause heat source pollution and waste of heat. Therefore, this utility model proposes a bridge steel structure coating drying equipment to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a coating and drying device for bridge steel structural components.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A bridge steel structure coating and drying equipment includes a base, with a drying chamber and a hot water exchange tank fixedly connected to the upper end of the base. The hot water exchange tank contains water and has a heat exchange coil inside. A stirring mechanism for agitating the water is also provided inside the hot water exchange tank. A pumping mechanism for pumping air into the heat exchange coil is provided on the side wall of the drying chamber. The pumping mechanism includes an air suction hood fixedly connected to the side wall of the drying chamber, with an exhaust fan rotatably connected to the inner wall of the air suction hood. The air suction hood and the heat exchange coil are connected via an air inlet pipe. An exhaust pipe is fixedly connected to the end of the heat exchange coil away from the air inlet pipe, and the exhaust pipe passes through the side wall of the hot water exchange tank and is externally connected to a purifier.
[0007] Preferably, a door is provided on the front side wall of the drying oven, and two racks are fixedly connected to the inner wall of the drying oven.
[0008] Preferably, the stirring mechanism includes a rotating rod rotatably connected between the inner walls of both ends of the hot water exchange tank, the rotating rod passing through one end side wall of the hot water exchange tank and being rotatably and sealingly connected thereto.
[0009] Preferably, a motor is fixedly connected to the side wall of the hot water tank, and the end of the output shaft of the motor is fixedly connected to the end of the rotating rod.
[0010] Preferably, a synchronous pulley is fixedly sleeved on both the end of the rotating rod and the shaft of the exhaust fan, and the two synchronous pulleys are connected by a synchronous belt drive.
[0011] Preferably, an electric heating plate is installed at the bottom of the drying oven.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. During the drying process, through the heat exchange coil and the air pumping mechanism, the output shaft of the drive motor rotates, which drives the rotating rod to rotate. Under the transmission of the synchronous pulley and synchronous belt, the exhaust fan rotates. The rotation of the exhaust fan can adsorb the hot air in the drying chamber and draw the hot air in through the air suction hood. The hot air enters the heat exchange coil through the air inlet pipe. The outer wall of the heat exchange coil comes into contact with the water inside the hot water tank to achieve heat exchange. This can realize the recovery of heat energy and avoid heat energy waste and heat pollution.
[0014] 2. By setting up a stirring mechanism, the motor output shaft rotates, which drives the rotating rod to rotate, thereby driving the stirring blades to rotate, thus stirring the water in the heat exchange tank. This allows the water in the heat exchange tank to fully contact the surface of the heat exchange coil, making the heat exchange more uniform. Attached Figure Description
