Hot-dip galvanizing pretreatment device

Abstract

The invention provides a hot-dip galvanizing pretreatment device including a heating chamber, a heating mechanism, a first fan, a second fan, vehicle rails, a vehicle frame, wheels, a fixed plate, hanging rings, a chain transmission mechanism, material hooks and a wet gas discharge port; the heating mechanism is arranged at the top end of the heating chamber, and the left side wall and the right side wall of the heating chamber are provided with the first fan and the second fan which are arranged oppositely; all fan blades of the first fan and the second fan can extend to the upper end and thelower end of the heating chamber; the top end of the heating chamber is also provided with the wet gas discharge port; the bottom end of the heating chamber is provided with the vehicle rails; the wheels at the bottom end of the vehicle frame are matched with the vehicle rails; the vehicle frame is in the heating chamber and is located at a middle position; the fixed plate is detachably arrangedat the top end of the vehicle frame, the bottom end of the fixed plate is provided with the chain transmission mechanism arranged in a closed loop, and the material hooks are arranged on transmissionjoints of the chain transmission mechanism. The hot-dip galvanizing pretreatment device has the beneficial effects that the preheating temperature is uniform, the phenomenon of local high temperatureis avoided from appearing, material transfer saves time and labor, and the operation efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of hot-dip galvanizing equipment, and in particular relates to a pre-treatment equipment for hot-dip galvanizing. Background technique [0002] Hot-dip galvanizing, also called hot-dip galvanizing or hot-dip galvanizing, is an effective metal anti-corrosion method, mainly used in metal structure facilities in various industries. In the process flow, the workpiece must be dried and preheated before the hot-dip galvanizing process to prevent the workpiece from being deformed due to a sharp rise in temperature during dipping, and to remove residual moisture to prevent zinc explosion and zinc liquid explosion. At present, the following two methods are mostly used for drying: one is to blow with hot air, which is not efficient in drying. The second is to use a hot plate to bake, but it is easy to cause the temperature at the bottom of the drying tank to be too high, so that the workpiece near the bottom is overh...

At present, the following two methods are mostly used for drying: one is to blow with hot air, which is not efficient in drying.

The second is to use a hot plate to bake, but it is easy to cause the temperature at the bottom of the drying tank to be too high, so that the workpiece near the bottom is overheated, resulting in the failure of the plating flux
