Description

Technical Field

[0001] This utility model belongs to the field of hot-dip galvanizing production technology, and in particular relates to a preheating device for hot-dip galvanizing production. Background Technology

[0002] Hot-dip galvanizing generally refers to the process of reacting molten metal with an iron substrate to create an alloy layer, thus bonding the substrate and the coating. The process begins with pickling the steel parts to remove iron oxide from their surface. After pickling, the parts are cleaned in an aqueous solution of ammonium chloride or zinc chloride, or a mixture of both, before being immersed in the hot-dip galvanizing bath. Hot-dip galvanizing offers advantages such as uniform coating, strong adhesion, and long service life. The preheating process in hot-dip galvanizing is a crucial link between pretreatment and galvanizing.

[0003] In the existing technology, the preheating device in hot-dip galvanizing production is relatively simple, and the preheating of the production base is not uniform enough, and it cannot quickly reach the temperature required for preheating, resulting in slow preheating efficiency. At the same time, it is inconvenient to fix the production base with different specifications during preheating. Therefore, a preheating equipment for hot-dip galvanizing production is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a preheating device for hot-dip galvanizing production to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a preheating device for hot-dip galvanizing production, comprising a preheating box and a rotating motor. The upper surface of the preheating box is an open structure. The rotating motor is fixedly installed on the front surface of the preheating box. The output end of the rotating motor is keyway connected to a rotating shaft. One end of the rotating shaft extends into the interior of the preheating box, and the rotating shaft is rotatably connected to the preheating box. A placement frame is welded to one end of the rotating shaft. The bottom surface of the placement frame is a grid plate structure. A positioning frame is placed on the upper surface of the placement frame. A connecting plate is welded inside the positioning frame. Two through holes are opened on the upper surface of the connecting plate, and sliding rods are slidably installed inside the two through holes.

[0007] Furthermore, a positioning grid plate is welded to the lower surface of both sliding rods, and the upper ends of the two sliding rods extend to the top of the connecting plate through through holes.

[0008] Furthermore, two connecting springs are installed between the upper surface of the positioning grid plate and the lower surface of the connecting plate, and the two connecting springs are wound around the periphery of the two sliding rods.

[0009] Furthermore, several positioning holes are passed through the peripheral sides of the two sliding rods, and positioning rods are engaged inside the positioning holes. The two positioning rods are positioned above the connecting plate.

[0010] Furthermore, a connecting shaft is rotatably installed on the inner wall of the preheating box, one end of which is fixedly connected to a surface of the placement frame. Support columns are welded to the periphery of the lower surface of the preheating box, and a hot air blower is fixedly installed on the lower surface of the preheating box.

[0011] Furthermore, the output end of the hot air blower is connected to the interior of the preheating box, and a controller is fixedly installed on one side of the preheating box. The controller is electrically connected to the rotating motor and the hot air blower respectively.

[0012] Furthermore, screw plates are welded to both sides of the placement frame, and side plates are welded to both sides of the positioning frame. The positions of the two side plates correspond to the positions of the two screw plates.

[0013] Furthermore, both of the side plates are screwed with fixing bolts on their upper surfaces, the lower ends of the two fixing bolts penetrating the upper surfaces of the two side plates, and the lower ends of the two fixing bolts are screwed and fixed to the screw plate.

[0014] This utility model has the following beneficial effects:

[0015] 1.

[0016] 2. This utility model uses a sliding rod, connecting spring and positioning rod structure to facilitate the adjustment of the position of the positioning grid plate according to different specifications of production base parts.

[0028] A positioning grid plate 210 is welded to the lower surface of the two sliding rods 209.

[0029] Several positioning holes 212 are passed through the sides of the two sliding rods 209. Positioning rods 213 are engaged inside the positioning holes 212. The two positioning rods 213 are set above the connecting plate 207 to facilitate the adjustment of the position of the positioning grid plate 210 according to the production base parts of different specifications.
