A heating galvanizing pot

Abstract

This invention relates to the field of galvanizing technology, specifically to a heated galvanizing pot, mainly comprising an outer shell, a pot body mounted on the inner wall of the outer shell, and a fixing block mounted on the top surface of the pot body. It also includes a pushing mechanism positioned above the pot body and a scraping mechanism positioned above the pot body. By activating a motor, a bidirectional lead screw rotates, causing two moving sleeves and two pushing plates to move closer together. During the movement of an adjusting rod to one end of an annular groove, the adjusting rod moves horizontally and then diagonally downwards, causing a moving strip to move downwards. The adjusting groove on the moving strip causes an adjusting column and a circular plate to rotate 90 degrees, which in turn causes a rotating shaft and a pushing plate to rotate 90 degrees. When the pushing plate is in a vertical position, the motor reverses, and the two pushing plates move away from each other. The two pushing plates push the zinc oxide layer on the surface of the liquid zinc in the pot body to both sides, allowing steel products to be immersed in the molten zinc for galvanizing. These zinc oxide films do not adhere to the surface of the steel products, thus ensuring the quality of the coating.

Description

Technical Field

[0001] This invention relates to the field of galvanizing technology, specifically to a heated galvanizing pot. Background Technology

[0002] In the field of metal surface treatment, hot-dip galvanizing is widely used in industries such as construction, transportation, and energy due to its excellent corrosion resistance. This process involves immersing steel products in molten zinc to form a zinc-iron alloy coating, effectively extending the service life of metal components. As the core equipment of a hot-dip galvanizing production line, the performance of the heating galvanizing pot directly affects the coating quality, production costs, and production efficiency.

[0003] After melting metallic zinc into molten zinc by heating a galvanizing pot, steel products are immersed in the molten zinc and then removed from the molten zinc. A zinc-iron alloy coating is formed on the surface of the steel products. However, a zinc oxide layer is formed on the surface of the molten zinc in the pot by reacting with oxygen in the air. The density of zinc oxide is less than that of liquid zinc, so the zinc oxide floats on the surface of the molten zinc and forms a continuous or semi-continuous film. When steel products are placed into the molten zinc, these zinc oxide films will stick to the surface of the steel products, thus affecting the coating quality. Summary of the Invention

[0011] Preferably, the connecting plate has a cavity inside, a movable block is slidably installed on the inner wall of the cavity, an elastic element two is fixedly installed on the side of the movable block, and the other end of the elastic element two is fixedly connected to one side of the inner wall of the cavity.

[0012] Preferably, a blocking block is fixedly installed on the side of the movable block. One end of the blocking block slides through the inner wall of the cavity and extends into the inside of the groove. One end of the blocking block abuts against the side of the connecting block, and the top surface of the blocking block is flush with the top surface of the connecting block.

[0013] Preferably, the movable sleeve has a T-shaped groove on its side, and a T-shaped block is slidably installed on the inner wall of the T-shaped groove. The side of the T-shaped block is fixedly connected to the side of the fixing strip through a connecting post.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a motor to rotate a bidirectional lead screw, which in turn moves two movable sleeves closer together and two push plates closer together. The movable sleeves move an adjusting rod within an annular groove. As the adjusting rod moves to one end of the annular groove, it moves horizontally and then diagonally downwards, causing a moving bar to move downwards. The moving bar, passing through the adjusting groove, rotates the adjusting column and circular plate 90 degrees, causing the rotating shaft and push plate to rotate 90 degrees. With the push plate in a vertical position, the motor is turned on in reverse, causing the two movable sleeves to move away from each other, and the two push plates to move away from each other. The two push plates push the zinc oxide layer on the surface of the liquid zinc in the pot to both sides, allowing steel products to be immersed in the liquid zinc for galvanizing. These zinc oxide films do not adhere to the surface of the steel products, thus ensuring the quality of the coating. When the two moving sleeves drive the two push plates to move to both sides, as the moving sleeves move to one end, they drive the scraper and connecting column to move. The connecting column moves in the control groove. As the connecting column moves from the horizontal groove to the inclined groove, it moves downward, driving the T-shaped block and the fixing strip to move downward. The fixing strip drives the scraper to move downward. The scraper removes the zinc oxide from the side of the push plate, ensuring the cleanliness of the side of the push plate. This ensures that when the push plate pushes the zinc oxide layer on the surface of liquid zinc, it can push more thoroughly to clean it, further improving the coating quality.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figures 1-9 As shown, this application provides a heated galvanizing pot, including: an outer shell 1, a pot body 101 installed on the inner wall of the outer shell 1, a fixing block 102 installed on the top surface of the pot body 101, a heating shell 105 installed on the inner wall of the pot body 101, an air inlet pipe 103 and an exhaust pipe 104 fixedly and through the top surface of the heating shell 105, one end of the air inlet pipe 103 and one end of the exhaust pipe 104 fixedly passing through the fixing block 102, and further including: The pushing mechanism 2 is located above the pot body 101. The pushing mechanism 2 includes a fixed frame 201 fixedly installed on the top surface of the pot body 101. Two movable sleeves 202 are slidably installed on the inner wall of the fixed frame 201. A rotating shaft 206 is rotatably installed on the side of the movable sleeve 202 through a bearing. A pushing plate 207 is fixedly installed at one end of the rotating shaft 206. Specifically, such as Figures 1-9 As shown, two limiting rods 203 are slidably installed on the inner walls of the two movable sleeves 202. The two ends of the limiting rods 203 are fixedly connected to the inner wall of the fixed frame 201. Two bidirectional screws 204 are threadedly installed on the inner walls of the two movable sleeves 202. The two ends of the bidirectional screws 204 are rotatably connected to the inner wall of the fixed frame 201 through bearings.

[0021] In this embodiment: the movable sleeve 202 is limited by the limiting rod 203, so that the movable sleeve 202 moves more stably. When the bidirectional lead screw 204 rotates, it drives the two movable sleeves 202 to move away from or closer to each other.

[0022] Specifically, such as Figures 1-9 As shown, a motor 205 is fixedly installed on the side of the fixed frame 201. One end of the output rod of the motor 205 is fixedly connected to one end of the bidirectional lead screw 204. A circular plate 208 is fixedly installed on the other end of the rotating shaft 206. An adjusting column 209 is fixedly installed on the side of the circular plate 208.

[0023] In this embodiment: the motor 205 applies power to the bidirectional lead screw 204, and the push plate 207 pushes the zinc oxide layer to both sides of the pot body 101.

[0024] Specifically, such as Figures 1-9 As shown, the movable sleeve 202 has a T-shaped groove 211 on its side, a T-shaped block 212 is slidably installed on the inner wall of the T-shaped groove 211, a movable strip 214 is fixedly installed on the side of the T-shaped block 212, and an adjustment groove 215 is provided through the movable strip 214. The inner wall of the adjustment groove 215 is slidably connected to the outer wall of the adjustment column 209.

[0025] In this embodiment: the T-shaped groove 211 limits the T-shaped block 212, making the movement of the T-shaped block 212 and the moving bar 214 more stable. When the moving bar 214 moves, the adjusting groove 215 on the moving bar 214 drives the adjusting column 209 to rotate at a certain angle. The adjusting column 209 drives the circular plate 208 and the rotating shaft 206 to rotate at a certain angle, which in turn drives the push plate 207 to rotate at a certain angle.

[0026] Specifically, such as Figures 1-9 As shown, an elastic element 213 is fixedly installed on the top surface of the T-shaped block 212. The upper end of the elastic element 213 is fixedly connected to the inner wall of the T-shaped groove 211. An arc groove 210 is provided on the side of the movable sleeve 202. The inner wall of the arc groove 210 is slidably connected to the outer wall of one end of the adjusting column 209.

[0027] In this embodiment: the elastic element 213 applies elastic force to the T-block 212, and the arc groove 210 limits the adjustment column 209, making the adjustment column 209 more stable during rotation.

[0028] Specifically, such as Figures 1-9 As shown, an adjusting rod 216 is fixedly installed on the side of the moving bar 214, and a connecting plate 217 is fixedly installed on the side of the fixed frame 201. A groove 218 is provided on the side of the connecting plate 217, and a connecting block 219 is provided inside the groove 218. The side of the connecting block 219 is fixedly connected to the side of the connecting plate 217 through a concave block 224. The inner wall of the groove 218 and the outer wall of the connecting block 219 form an annular groove. The two ends of the annular groove are oblique, and the inner wall of the annular groove is slidably connected to the outer wall of the adjusting rod 216.

[0029] In this embodiment: through the annular groove, and the two ends of the annular groove are oblique, when the adjusting rod 216 moves horizontally to the two ends, the adjusting rod 216 will move vertically.

[0030] Specifically, such as Figures 1-9As shown, the connecting plate 217 has a cavity 220 inside, and a movable block 221 is slidably installed on the inner wall of the cavity 220. An elastic element 223 is fixedly installed on the side of the movable block 221, and the other end of the elastic element 223 is fixedly connected to one side of the inner wall of the cavity 220.

[0031] In this embodiment, the elastic element 223 is used to apply elastic force to the moving block 221.

[0032] Specifically, such as Figures 1-9 As shown, a blocking block 222 is fixedly installed on the side of the movable block 221. One end of the blocking block 222 slides through the inner wall of the cavity 220 and extends into the interior of the groove 218. One end of the blocking block 222 abuts against the side of the connecting block 219, and the top surface of the blocking block 222 is flush with the top surface of the connecting block 219.

[0033] In this embodiment: When the two adjusting rods 216 move to both sides, and the adjusting rods 216 move obliquely upward at one end of the annular groove, the adjusting rods 216 push the blocking block 222 to move. The blocking block 222 drives the moving block 221 to move and squeezes the elastic element 223. At this time, when the adjusting rods 216 move above the blocking block 222, the elastic element 223 pushes the moving block 221 and the blocking block 222 to rebound. The top of the blocking block 222 blocks the adjusting rods 216. When the two adjusting rods 216 approach each other, the adjusting rods 216 are in a high position and move horizontally. At this time, the pushing plate 207 is in a horizontal state and will not come into contact with the liquid zinc.

[0034] The scraping mechanism 3 is located above the pot body 101. The scraping mechanism 3 includes a scraper 305 that is slidably installed on the side of the push plate 207. A fixing strip 304 is fixedly installed on the top surface of the scraper 305.

[0035] Specifically, such as Figures 1-9 As shown, the movable sleeve 202 has a T-shaped groove 301 on its side, and a T-shaped block 302 is slidably installed on the inner wall of the T-shaped groove 301. The side of the T-shaped block 302 is fixedly connected to the side of the fixing strip 304 through the connecting post 303.

[0036] In this embodiment: the T-shaped groove 301 is used to limit the movement of the T-shaped block 302, so that the T-shaped block 302 and the connecting column 303 can move more stably.

[0037] Specifically, such as Figures 1-9 As shown, a fixing plate 306 is fixedly installed on the inner wall of the fixing frame 201. A control groove 307 is provided through the fixing plate 306. The control groove 307 is composed of a horizontal groove and an oblique groove. The inner wall of the control groove 307 is slidably connected to the outer wall of the connecting column 303.

[0038] In this embodiment: when the connecting column 303 moves from the horizontal groove to the inclined groove, the connecting column 303 drives the fixing strip 304 and the scraper 305 to push downward, and the scraper 305 removes the zinc oxide on the side of the push plate 207.

[0039] Specifically, the solution is as follows: combustion gas and oxygen enter through the intake pipe 103 and burn in the heating shell 105. Exhaust gas is then discharged from the exhaust pipe 104. The heating shell 105 and the pot body 101 heat and melt the zinc into a liquid state. The motor 205 is turned on, driving the bidirectional lead screw 204 to rotate. This causes the two moving sleeves 202 to move closer together, and the two push plates 207 to move closer together. The moving sleeves 202 drive the adjusting rod 216 to move in the annular groove. During the movement of the adjusting rod 216 to one end of the annular groove, under the action of the elastic element 213 and the annular groove, the adjusting rod 216 moves horizontally. After moving downwards, the moving strip 214 moves downwards. The moving strip 214 drives the adjusting column 209 and the circular plate 208 to rotate 90 degrees through the adjusting groove 215, which in turn drives the rotating shaft 206 and the push plate 207 to rotate 90 degrees. The push plate 207 is in a vertical position. The motor 205 is turned on to reverse, and the two moving sleeves 202 move away from each other, which in turn drives the two push plates 207 to move away from each other. The two push plates 207 push the zinc oxide layer on the surface of the liquid zinc in the pot 101 to both sides. At the same time, as the two moving sleeves 202 move away from each other and move to the edge, the moving sleeves 202 drive the scraper. 305 and connecting column 303 move. Connecting column 303 moves in control groove 307. During the process of connecting column 303 moving from horizontal groove to inclined groove, connecting column 303 moves downward, driving T-shaped block 302 and fixing strip 304 to move downward. Fixing strip 304 drives scraper 305 to move downward. Scraper 305 removes zinc oxide from the side of push plate 207, ensuring the cleanliness of the side of push plate 207. At the same time, when the two adjusting rods 216 move to the outermost edge, when the adjusting rods 216 move obliquely upward at one end of the annular groove, the adjusting rods 216 push the blocking block 222. The movement is initiated by the blocking block 222, which causes the moving block 221 to move and press against the elastic element 223. At this time, when the adjusting rod 216 moves above the blocking block 222, the elastic element 223 pushes the moving block 221 and the blocking block 222 to rebound. The top of the blocking block 222 blocks the adjusting rod 216. When the two adjusting rods 216 approach each other, the adjusting rod 216 is in a high position and moves horizontally. At this time, the pushing plate 207 is in a horizontal state and will not come into contact with the liquid zinc. After the steel product is immersed in the molten zinc liquid for galvanizing, the steel is taken out of the zinc liquid, and the galvanizing is completed.
