Description

Technical Field

[0001] The invention relates to the technical field of steel strip galvanizing, in particular to a galvanizing device suitable for steel structural parts. Background Art

[0002] Galvanized steel strip is a cold-rolled or hot-rolled, long and narrow steel strip plate coated with a layer of raw material called (zinc) to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The hot-dip galvanized steel strip substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is integrated with the pure zinc layer and the strip steel substrate, so it has strong corrosion resistance. Therefore, the steel structure parts made of steel strip in the later stage are also highly corrosion-resistant and more beautiful. However, during the use of the galvanizing device for steel strips processed into steel structural parts, zinc slag will be generated on the zinc liquid surface and inside the steel strip during galvanizing. However, the treatment of zinc slag is carried out by the staff using tools such as hook spoons to scoop out the zinc slag. This method is not only time-consuming and labor-intensive when handling the zinc slag, but also the hook spoon carries more zinc liquid when scooping out the zinc slag, which will cause a waste of zinc liquid. Therefore, we propose a galvanizing device suitable for steel structural parts to solve the above problems. Summary of the invention

A rotating paddle 9 fixed to the surface of the cylinder 7 is arranged above the filter bucket 8. The interior of the cylinder 7 is rotatably connected with a spiral blade 10 through a bearing. A gear ring 11 is fixed inside the sink groove opened on the top of the bevel gear disk 6. A transmission gear 12 is fixed on the surface of the spiral blade 10. The gear ring 11 is meshed with the transmission gear 12. Both side walls of the movable seat 2 are rotatably connected with a transmission shaft 13 through a bearing. A bevel gear 14 is fixed at one end of the transmission shaft 13. The bevel gears 14 are meshed with the bevel gear disk 6. A reciprocating rod 15 is movably connected to one side wall of the bevel gear 14 through a T-axis. Guide blocks 16 adapted to the reciprocating rod 15 are fixed to the inner walls of both sides of the movable seat 2. The reciprocating rod 15 slides on the relative On the corresponding guide block 16, a knocking plate 17 used in conjunction with the two reciprocating rods 15 is fixed on the surface of the cylinder 7, and two collecting buckets 18 are connected and fixed to the outer wall of the cylinder 7. Two reinforcing plates 25 are fixed to the outer wall of the cylinder 7. The other ends of the reinforcing plates 25 are respectively fixedly connected to the corresponding collecting buckets 18, which can play an auxiliary supporting role for the collecting buckets 18 so that they will be more stable after being fixed. A blocking component 19 is provided on one side wall of the collecting bucket 18, and a cooling component 20 for quickly cooling the zinc slag collected in the two collecting buckets 18 is provided on the top of the moving seat 2. An arc filter screen 21 is fixed inside the two openings opened on the surface of the cylinder 7. When this galvanizing device suitable for steel structural parts is used, it is mainly used for steel strips before being processed into steel structures. During the galvanizing process, the steel strip can be moved from any side of the cylinder 7 to the inside of the galvanizing tank 1, and then the surface can be galvanized. During the galvanizing process, the motor can be started to drive the cylinder 7 to rotate. After the cylinder 7 rotates, the filter bucket 8 and the rotating paddle 9 will be driven to rotate. The rotation of the rotating paddle 9 can continuously stir the zinc liquid, so that the zinc slag is not easy to form a stable layer on the surface of the zinc liquid, thereby reducing the accumulation of zinc slag. During the rotation of the rotating paddle 9, the spiral blade 10 will rotate to collect part of the zinc slag concentrated in the center of the filter bucket 8 into the inside of the collecting bucket 18, and at this time, when the zinc slag moves up, the zinc liquid will also move up, and after the zinc liquid moves up to the arc filter 21, it will flow back to the inside of the galvanizing tank 1.When the filter hopper 8 is moved upward, the filter hopper 8 and the filter hopper 8 will be moved upward, and the filter hopper 8 will be moved upward to filter the zinc slag in the galvanizing tank 1. The separation speed of zinc liquid can be increased, and the zinc slag collected inside the filter bucket 8 can also be assisted to slide and concentrate to its center position, and at the same time, a large amount of zinc liquid can be prevented from being carried inside the zinc slag, thereby avoiding the waste of zinc liquid.

In the transmission process, since the number of teeth of the gear ring 11 is greater than the number of teeth of the transmission gear 12, the rotation speed of the transmission gear 12 will be faster than the rotation speed of the gear ring 11. At this time, the rotation speed of the spiral blade 10 will be greater than the rotation speed of the cylinder 7, so the spiral blade 10 can effectively push the zinc slag to move upward inside the cylinder 7. At this time, exhaust holes are provided on the backs of the two collection buckets 18 to discharge the used air, and the exhaust holes are not shown in the figure. ,

[0030] like Figure 1 As shown, in some embodiments, the lifting mechanism 3 includes a mounting frame 301 fixed to the outer wall of the galvanized pool body 1, and two screw rods 302 are rotatably connected between the upper and lower inner walls of the mounting frame 301 through bearings, and the movable seat 2 is threadedly connected to the surfaces of the two screw rods 302, and the top of the mounting frame 301 is rotatably connected to two connecting shafts 303 through bearings, and sprockets 304 are fixed on the surfaces of the two screw rods 302 and the two connecting shafts 303, and the four sprockets 304 are connected by chains 305. When in use, one of the screw rods 302 is driven to rotate by starting the motor, and then with the cooperation of the connecting shaft 303, the sprocket 304 and the chain 305, the two screw rods 302 can be driven to rotate synchronously at the same time, so as to save production costs. Finally, after the two screw rods 302 are rotated, the movable seat 2 can be moved up and down.

The two air outlet ducts of the box 2001 are both installed with air inlet check valves, and the four openings opened on the surface of the box 2001 are all fixed with heat sinks 2002.
