Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing devices, and particularly relates to a hot-dip galvanizing device for iron-based castings. Background Technique

[0002] Hot dip galvanizing is a process technology in which metals such as steel, stainless steel, and cast iron are immersed in molten liquid metal or alloy to obtain a coating. Hot-dip galvanized products play an inestimable and irreplaceable role in reducing corrosion and extending the service life of steel, saving energy and materials. At the same time, coated steel is also a short-term product with high added value.

[0003] When the existing hot-dip galvanizing device is galvanizing, since the galvanizing material is exposed, it is easy to oxidize. When the iron-based casting is directly added to the galvanizing tank, the oxidized galvanized material on the surface of the galvanizing tank is easy to adhere to the surface of the iron casting, thus affecting the galvanizing quality of the iron casting. For this reason, we propose a hot-dip galvanizing device for iron-based castings to facilitate scraping the oxidized galvanized material on the surface of the galvanizing tank. Content of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a hot-dip galvanizing device for iron-based castings.

[0005] The technical solution adopted by the utility model to solve its technical problems is a hot-dip galvanizing device for iron-based castings, including a bottom plate and a concave frame. A scraping mechanism is installed at the top of the bottom plate. The scraping mechanism is composed of a galvanizing tank, a horizontal frame, a scraping plate, a motor A, a horizontal groove, a limiting plate, and a threaded rod. A galvanizing tank is installed at the top of the bottom plate. A horizontal frame is welded to the wall of the galvanizing tank. One end of the horizontal frame is installed with a motor A through bolts. The output end of the motor A is installed with a threaded rod. The limiting plate is threadedly connected to the rod wall of the threaded rod. Horizontal grooves are opened on the frame wall of the horizontal frame and the wall of the galvanizing tank. The limiting plate penetrates through the horizontal groove. The other end of the limiting plate is welded with a scraping plate. The scraping plate is located inside the galvanizing tank.

[0006] By adopting the above technical solution, when scraping the oxidized galvanized material on the inner surface of the galvanizing tank, since a scraping mechanism is installed at the top of the bottom plate, and the scraping mechanism is composed of a galvanizing tank, a horizontal frame, a scraping plate, a motor A, a horizontal groove, a limiting plate, and a threaded rod, and the galvanizing tank stores galvanizing material, the motor A is controlled by a controller, so that the motor A drives the threaded rod at its output end to rotate. Since the limiting plate is threadedly connected to the rod wall of the threaded rod and the limiting plate penetrates through the horizontal grooves of the horizontal frame and the galvanizing tank, when the threaded rod rotates, the limiting plate moves in the horizontal groove, so that the limiting plate drives the scraping plate to move, and the scraping plate moves inside the galvanizing tank, so that the scraping plate scrapes the oxidized galvanized material in the galvanizing tank, so that the oxidized galvanized material is discharged into the collection box through the slag discharge groove, avoiding the oxidized galvanized material from contacting the iron-based casting and affecting the galvanizing quality of the iron-based casting.

[0007] Specifically, it further includes a hoisting mechanism, and the hoisting mechanism is installed on the wall of the concave frame.

[0008] By adopting the above technical solution, the honeycomb box can be hoisted and lifted by the hoisting mechanism.

[0009] Specifically, the hoisting mechanism is composed of a motor B, vertical plates, a honeycomb box, a winding disc, a steel wire rope and a lifting ring. A pair of symmetric motors B are installed on the wall of the concave frame. Two groups of symmetric vertical plates are welded on the wall of the concave frame. A winding disc is rotatably connected between the two groups of vertical plates, and one end of the winding disc is connected to the output end of the motor B. The steel wire rope is wound on the disc wall of the winding disc. A pair of symmetric lifting rings are welded on the wall of the honeycomb box, and the other end of the steel wire rope is connected to the ring wall of the lifting ring.

[0010] By adopting the above technical solution, when galvanizing the iron-based casting, since the hoisting mechanism is installed on the wall of the concave frame and the hoisting mechanism is composed of a motor B, vertical plates, a honeycomb box, a winding disc, a steel wire and a lifting ring. After the personnel place the iron-based casting into the honeycomb box, the motor B is controlled through the controller, so that the motor B drives the winding disc at its output end to rotate. Since the steel wire rope is wound on the disc wall of the winding disc and the other end of the steel wire rope is connected to the lifting ring on the wall of the honeycomb box, the honeycomb box is moved into the galvanizing box through the winding of the steel wire rope. After the liquid galvanizing material enters the honeycomb box through the honeycomb holes at the honeycomb box, the iron-based casting is galvanized.

[0011] Specifically, the concave frame is installed on the wall of the bottom plate through bolts, a collecting box is installed on the wall of the galvanizing box, and a slag discharge groove is opened on the wall of the galvanizing box.

[0012] By adopting the above technical solution, it is convenient to fix the concave frame, and the oxidized galvanizing material is discharged into the collecting box through the slag discharge groove.

[0013] Specifically, a controller for controlling the motor A and the motor B is installed on the wall of the concave frame.

[0014] By adopting the above technical solution, the motor A and the motor B can be controlled through the controller.

[0015] The beneficial effects of the present utility model:

[0016] (1) For a hot-dip galvanizing device of an iron-based casting described in the present utility model, when scraping the surface galvanized and oxidized material in the galvanizing box, since a scraping mechanism is installed at the top of the bottom plate, the scraping mechanism is composed of a galvanizing box, a horizontal frame, a scraping plate, a motor A, a horizontal groove, a limiting plate, and a threaded rod. The galvanizing box contains galvanized material. Thus, the motor A is controlled by a controller, causing the motor A to drive the threaded rod at its output end to rotate. Since the limiting plate is threadedly connected to the rod wall of the threaded rod and the limiting plate penetrates the horizontal grooves at the horizontal frame and the galvanizing box, when the threaded rod rotates, the limiting plate moves in the horizontal groove, and thus the limiting plate drives the scraping plate to move, causing the scraping plate to move in the galvanizing box. Consequently, the scraping plate scrapes the oxidized galvanized material in the galvanizing box, and the oxidized galvanized material is discharged into the collection box through the slag discharge groove, preventing the oxidized galvanized material from contacting the iron-based casting and affecting the galvanizing quality of the iron-based casting.

[0017] (2) For a hot-dip galvanizing device of an iron-based casting described in the present utility model, when galvanizing the iron-based casting, since a hoisting mechanism is installed on the wall of the concave-shaped frame, the hoisting mechanism is composed of a motor B, a vertical plate, a honeycomb box, a winding disc, a steel wire rope, and a lifting ring. After a person places the iron-based casting into the honeycomb box, the motor B is controlled by a controller, causing the motor B to drive the winding disc at its output end to rotate. Since the steel wire rope is wound around the disc wall of the winding disc and the other end of the steel wire rope is connected to the lifting ring on the wall of the honeycomb box, through the winding of the steel wire rope, the honeycomb box is moved into the galvanizing box. Then, the liquid galvanized material enters the honeycomb box through the honeycomb holes at the honeycomb box, and thus the iron-based casting is galvanized. Brief Description of the Drawings

Horizontal grooves 205 are opened on the frame wall of the horizontal frame 202 and the box wall of the galvanizing box 201. The limiting plate 206 penetrates through the horizontal groove 205. The other end of the limiting plate 206 is welded with a scraper 203. The scraper 203 is located inside the galvanizing box 201.

[0025] When in use, when scraping the surface galvanized and oxidized material in the galvanizing box 201, since the scraping mechanism 2 is installed at the top of the bottom plate 1 and the scraping mechanism 2 is composed of a galvanizing box 201, a horizontal frame 202, a scraper 203, a motor A 204, a horizontal groove 205, a limiting plate 206 and a threaded rod 207, and the galvanizing box 201 stores galvanized material, the controller 4 is used to control the motor A 204, so that the motor A 204 drives the threaded rod 207 at its output end to rotate. Since the limiting plate 206 is threadedly connected to the rod wall of the threaded rod 207 and the limiting plate 206 penetrates through the horizontal grooves 205 on the horizontal frame 202 and the galvanizing box 201, when the threaded rod 207 rotates, the limiting plate 206 moves in the horizontal groove 205, so that the limiting plate 206 drives the scraper 203 to move, so that the scraper 203 moves inside the galvanizing box 201, so that the scraper 203 scrapes the oxidized galvanized material in the galvanizing box 201, so that the oxidized galvanized material is discharged into the collection box 5 through the slag discharge groove 7, avoiding the oxidized galvanized material from contacting the iron-based casting and affecting the galvanizing quality of the iron-based casting.

[0026] As shown in Figure 1 , it further includes a hoisting mechanism 6. The hoisting mechanism 6 is installed on the frame wall of the concave frame 3.

[0027] When in use, the honeycomb box 603 can be hoisted and lifted by the hoisting mechanism 6.

[0028] As shown in Figure 1 andFigure 3 As shown, the hoisting mechanism 6 is composed of a motor B601, a vertical plate 602, a honeycomb box 603, a winding disc 604, a steel wire rope 605 and a lifting ring 606. A pair of symmetric motor B601 is installed on the wall of the concave frame 3. Two groups of symmetric vertical plates 602 are welded on the wall of the concave frame 3. A winding disc 604 is rotatably connected between the two vertical plates 602, and one end of the winding disc 604 is connected to the output end of the motor B. The steel wire rope 605 is wound on the wall of the winding disc 604. A pair of symmetric lifting rings 606 are welded on the wall of the honeycomb box 603. The other end of the steel wire rope 605 is connected to the wall of the lifting ring 606.

[0029] When in use, when galvanizing the iron-based casting, since the hoisting mechanism 6 is installed on the wall of the concave frame 3 and the hoisting mechanism 6 is composed of a motor B601, a vertical plate 602, a honeycomb box 603, a winding disc 604, a steel wire rope 605 and a lifting ring 606. After the personnel place the iron-based casting into the honeycomb box 603, the motor B601 is controlled by the controller 4, so that the motor B601 drives the winding disc 604 at its output end to rotate. Since the steel wire rope 605 is wound on the wall of the winding disc 604 and the other end of the steel wire rope 605 is connected to the lifting ring 606 on the wall of the honeycomb box 603, the honeycomb box 603 is moved into the galvanizing box 201 by winding the steel wire rope 605. After the liquid galvanizing material enters the honeycomb box 603 through the honeycomb holes at the honeycomb box 603, the iron-based casting is galvanized.

[0030] As Figure 1 shown, the concave frame 3 is installed on the wall of the bottom plate 1 by bolts. A collection box 5 is installed on the wall of the galvanizing box 201. A slag discharge groove 7 is opened on the wall of the galvanizing box 201.

[0031] When in use, it is convenient to fix the concave frame 3. The oxidized galvanizing material is discharged into the collection box 5 through the slag discharge groove 7.

[0032] As Figure 1 shown, a controller 4 for controlling the motor A204 and the motor B601 is installed on the wall of the concave frame 3.

[0033] When in use, the motor A204 and the motor B601 can be controlled through the controller 4.

[0034] When the utility model is in use, when scraping the surface galvanized and oxidized material in the galvanizing box 201, since the scraping mechanism 2 is installed at the top of the bottom plate 1, the scraping mechanism 2 is composed of a galvanizing box 201, a horizontal frame 202, a scraper 203, a motor A 204, a horizontal groove 205, a limiting plate 206 and a threaded rod 207. The galvanizing box 201 stores galvanized material. Thus, the controller 4 controls the motor A 204, so that the motor A 204 drives the threaded rod 207 at its output end to rotate. Since the limiting plate 206 is threadedly connected to the rod wall of the threaded rod 207 and the limiting plate 206 penetrates through the horizontal groove 205 at the horizontal frame 202 and the galvanizing box 201, when the threaded rod 207 rotates, the limiting plate 206 moves in the horizontal groove 205. Thus, the limiting plate 206 drives the scraper 203 to move, so that the scraper 203 moves in the galvanizing box 201. Thus, the scraper 203 scrapes the oxidized galvanized material in the galvanizing box 201, so that the oxidized galvanized material is discharged into the collection box 5 through the slag discharge groove 7, avoiding the contact between the oxidized galvanized material and the iron-based casting and affecting the galvanizing quality of the iron-based casting. When galvanizing the iron-based casting, since the hoisting mechanism 6 is installed on the wall of the concave-shaped frame 3, the hoisting mechanism 6 is composed of a motor B 601, a vertical plate 602, a honeycomb box 603, a winding disc 604, a steel wire rope 605 and a lifting ring 606. After the personnel place the iron-based casting into the honeycomb box 603, the controller 4 controls the motor B 601, so that the motor B 601 drives the winding disc 604 at its output end to rotate. Since the steel wire rope 605 is wound on the disc wall of the winding disc 604 and the other end of the steel wire rope 605 is connected to the lifting ring 606 on the box wall of the honeycomb box 603, through the winding of the steel wire rope 605, the honeycomb box 603 moves into the galvanizing box 201. After the liquid galvanized material enters the honeycomb box 603 through the honeycomb holes at the honeycomb box 603, the iron-based casting is galvanized.
