Description

Technical Field

[0001] This application relates to hot-dip galvanizing, and more particularly to a drying apparatus for hot-dip galvanizing surface processing. Background Technology

[0002] Hot-dip galvanizing is a process in which molten metal reacts 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. Drying the metal parts is necessary during the hot-dip galvanizing process.

[0003] In the existing technology, during the drying process of hot-dip galvanizing on the surface of the processed material, some hot-dip galvanizing liquid will drip from the processed material. Over time, a large amount of hot-dip galvanizing liquid will accumulate, which will not only pollute the drying equipment and affect the drying effect, but also waste the galvanizing liquid. In addition, some of the hot-dip galvanizing liquid will accumulate on the surface of the steel in a liquid state. After the drying process, it will dry quickly and adhere to the surface of the material, resulting in some hot-dip galvanized lumps protruding on the surface of the material, which will affect the appearance of the processed material. Utility Model Content

[0004] The purpose of this application is to provide a drying device for hot-dip galvanizing surface processing, which has the advantages of collecting the zinc plating liquid dripping from the processed material and reducing the galvanizing liquid from clumping and adhering to the material after drying. It solves the problems that the accumulation of dripping zinc plating liquid not only pollutes the drying equipment and affects the drying effect, but also wastes the zinc plating liquid and causes some hot-dip galvanized lumps to protrude on the surface of the material, affecting the appearance of the processed material.

[0005] The drying equipment for hot-dip galvanizing surface processing provided in this application adopts the following technical solution: it includes a drying box, two fixed frames are fixedly connected to one side surface of the drying box, a hot air fan is fixedly connected inside the fixed frames, several rollers are rotatably connected between the inner walls of one side of the drying box, rotating columns are rotatably connected to the inner walls of one side of the drying box, a fixed plate is fixedly connected to the end of the rotating column away from the drying box, several support columns are rotatably connected to the side of the fixed plate away from the rotating column, a first slide rail is fixedly connected to both ends of the side of the fixed plate away from the support columns, two clamping frames are slidably connected to the outer side of the first slide rail, and two fixed rods are fixedly connected to the side of the fixed plate away from the support columns. By adopting the above technical solution, the rotating column can cause the fixed plate to rotate after rotation, thereby tilting the fixed plate. After the fixed plate tilts, the support column will cause the plate to be dried to tilt as well. Then, two hot air blowers can blow air onto the bottom tilted surface of the plate to dry the bottom surface of the plate. During the drying process, some galvanized liquid drips into the inside of the drying chamber, and the dripping is vertical. The motor can slowly rotate the rotating column during the drying process to adjust the contact point between the plate and the air outlet shell, thereby ensuring that the hot air dries the plate evenly. This solves the problem of galvanized liquid dripping and accumulating together, which not only pollutes the drying equipment and affects the drying effect, but also wastes galvanized liquid and causes galvanized liquid to dry and adhere to the surface of the material, resulting in some hot-dip galvanized lumps protruding on the surface of the material, affecting the appearance of the processed material.

[0006] Preferably, two air outlet shells are fixedly connected inside one side of the drying box, and one end of each of the two air outlet shells is connected to the air outlet of two hot air blowers respectively. By adopting the above technical solution, the air outlet shell can transmit the hot air from the hot air blower, so that the hot air is blown into the drying surface of the board.

[0007] Preferably, a motor is fixedly connected to both sides of the drying box, and the output shaft of the motor passes through the drying box and is fixedly connected to the rotating column; By adopting the above technical solution, the motor can provide power to the rotating column, causing the rotating column to rotate.

[0008] Preferably, a support ring is fixedly connected to the inner walls of both sides of the drying box, and an annular groove is provided on the side of the support ring away from the drying box; By adopting the above technical solution, the support ring is located on the outside of the rotating column, and the support ring can support the fixed plate.

[0009] Preferably, both ends of the fixed plate away from the support column are fixedly connected to movable blocks, and the end of the movable block away from the fixed plate is located in the inner annular groove of the support ring and is slidably connected to the annular groove. By adopting the above technical solution, when the moving block is fixedly connected to the fixed plate, it can slide on the side of the support ring after the fixed plate rotates, thereby providing limiting support for the fixed plate.

[0010] Preferably, each of the two clamping frames is fixedly connected to an electric push rod on its side, the output shaft of the electric push rod is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to two other clamping frames; By adopting the above technical solution, the electric push rod can provide power to the clamping frame, enabling the clamping frame to move, and the clamping frame can clamp and fix the plate after moving.

[0011] Preferably, a rotating plate is rotatably connected to the end of the fixing rod away from the fixing plate, and positioning blocks are rotatably connected to both ends of one side of the rotating plate; By adopting the above technical solution, a groove is provided on the side of the positioning block away from the rotating plate, so that the two positioning blocks can be raised and lowered synchronously after the rotating plate rotates.

[0012] Preferably, two positioning rods are fixedly connected between two adjacent clamping frames, and a second slide rail is fixedly connected to the side of the positioning rod. The positioning block is located outside the second slide rail and is slidably connected to the second slide rail. By adopting the above technical solution, the positioning block can make the rotating plate rotate when it slides on the outside of the second slide rail, and the positioning rod can make the two adjacent clamping frames move synchronously.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. This drying equipment for hot-dip galvanized surface processing, through the arrangement of a drying chamber, hot air blower, air outlet, roller, rotating column, motor, fixed plate, and support column, enables the device to operate by rotating the rotating column via the motor. The rotating column rotates, causing the fixed plate to rotate and tilt. This tilting of the fixed plate, in turn, causes the support column to tilt the sheet material to be dried. Two hot air blowers then blow air through the air outlet shell onto the tilted bottom surface of the sheet material, thus drying the bottom surface. During drying, some galvanized liquid drips into the drying chamber, falling vertically. The motor slowly rotates the rotating column to adjust the contact point between the sheet material and the air outlet shell, ensuring uniform drying of the sheet material by the hot air. This solves the problems of galvanized liquid accumulation, which not only contaminates the drying equipment and affects the drying effect, but also wastes galvanized liquid and causes galvanized liquid to dry and adhere to the material surface, resulting in protruding hot-dip galvanized lumps that affect the appearance of the processed material.

[0014] 2. This drying equipment for hot-dip galvanizing surface processing, through the arrangement of a motor, rotating column, fixed plate, support column, clamping frame, first slide rail, electric push rod, second slide rail, positioning rod, rotating plate, and positioning block, allows the device to move two adjacent clamping frames via the electric push rod during use. After the two adjacent clamping frames move, they clamp the plate, thus fixing it. After the plate is fixed, the motor can be started to make the fixed plate drive the support column to rotate. After the support column rotates, it can cause the plate to flip, thereby changing the drying surface of the plate. This solves the problem that most devices can only dry one side of the plate, which means that when drying both sides of the plate, the plate needs to be removed and flipped to dry, thus wasting the drying efficiency.

[0017] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0018] Example 1: A drying device for hot-dip galvanizing surface processing, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4The system includes a drying oven 1. Two fixed frames 2 are fixedly connected to one side surface of the drying oven 1. A hot air blower 3 is fixedly connected inside the fixed frame 2. Several rollers 5 are rotatably connected between the inner walls of one side of the drying oven 1. Rotating columns 6 are rotatably connected to the inner walls of one side of the drying oven 1. A fixed plate 8 is fixedly connected to the end of the rotating column 6 away from the drying oven 1. Several support columns 9 are rotatably connected to the side of the fixed plate 8 away from the rotating column 6. First slide rails 12 are fixedly connected to both ends of the side of the fixed plate 8 away from the support columns 9. Two clamping frames 13 are slidably connected to the outer side of the first slide rail 12. Two fixed rods 16 are fixedly connected to the side of the fixed plate 8 away from the support columns 9. Two air outlet shells 4 are fixedly connected inside one side of the drying oven 1. One end of each air outlet shell 4 is connected to the air outlet of the two hot air blowers 3. Motors 7 are fixedly connected to the surfaces of one side of the drying oven 1. The output shaft of the motor 7 passes through the drying oven 1 and is fixedly connected to the rotating column 6. The motor 7 passes through the drying oven 1, the hot air blower 3, the air outlet, and the rollers 5. The arrangement of shaft 5, rotating column 6, motor 7, fixed plate 8, and support column 9 allows the device to rotate via motor 7 during operation. The rotating column 6 rotates, causing the fixed plate 8 to rotate and tilt. This tilting of the fixed plate 8, in turn, causes the support column 9 to tilt the sheet material to be dried. Then, two hot air blowers 3 through the air outlet shell 4 to blow air onto the tilted bottom surface of the sheet material, thus drying its bottom surface. During drying, some galvanized liquid drips into the drying chamber 1, falling vertically. Motor 7 slowly rotates the rotating column 6 during drying, adjusting the contact point between the sheet material and the air outlet shell 4. This ensures even drying of the sheet material by hot air, preventing the galvanized liquid from accumulating, contaminating the drying equipment, affecting drying efficiency, wasting galvanized liquid, and causing galvanized lumps to protrude from the material surface, affecting the appearance of the processed material.

[0019] Example 2: A drying device for hot-dip galvanizing surface processing, referring to... Figure 3 , Figure 4 , Figure 5The drying oven 1 has two inner walls on both sides with support rings 10 fixedly connected. The support rings 10 have annular grooves on the side away from the drying oven 1. Movable blocks 11 are fixedly connected to both ends of the fixed plate 8 on the side away from the support column 9. The end of the movable block 11 away from the fixed plate 8 is located inside the annular groove of the support ring 10 and slidably connected to the annular groove. Electric push rods 14 are fixedly connected to the sides of two clamping frames 13. A connecting plate 15 is fixedly connected to the output shaft of the electric push rod 14. The connecting plate 15 is fixedly connected to the other two clamping frames 13. A rotating plate 19 is rotatably connected to the end of a fixed rod 16 away from the fixed plate 8. Positioning blocks 20 are rotatably connected to both ends of one side of the rotating plate 19. Two positioning rods 18 are fixedly connected between two adjacent clamping frames 13. A second slide rail 17 is fixedly connected to the side of the positioning rod 18, and the positioning blocks 20 are located on the second slide rail 17. The outer side of the plate is slidably connected to the second slide rail 17. Through the arrangement of motor 7, rotating column 6, fixed plate 8, support column 9, clamping frame 13, first slide rail 12, electric push rod 14, second slide rail 17, positioning rod 18, rotating plate 19 and positioning block 20, the device can move two adjacent clamping frames 13 by electric push rod 14 during use. After the two adjacent clamping frames 13 move, they will clamp the plate and fix it. After the plate is fixed, motor 7 can be started to drive fixed plate 8 to drive support column 9 to rotate. After the support column 9 rotates, it can drive the plate to flip, thereby changing the drying surface of the plate. This solves the problem that most devices can only dry one side of the plate, which means that when drying both sides of the plate, the plate needs to be removed and flipped to dry, thus wasting the drying efficiency.

[0020] The implementation principle of this application embodiment is as follows: In use, the board to be dried is placed between several rollers 5, and then the board is pushed to move, so that the board moves on the top of the rollers 5 and moves to the side of the fixed plate 8. At this time, the board is located between several support columns 9, and the support columns 9 support the board. Then, the electric push rod 14 is activated. The output shaft of the electric push rod 14 causes the connecting plate 15 to rise and fall. After the connecting plate 15 moves, the clamping frame 13 fixedly connected to it rises and falls. After a part of the clamping frame 13 rises and falls, the positioning rod 18 rises and falls. After the positioning rod 18 rises and falls, the second slide rail 17 rises and falls. Then, the positioning block 20 follows the positioning rod 18 to rise and fall. During the rise and fall, the positioning block 20 causes the rotating plate 19 to rotate. After the rotating plate 19 rotates, the positioning block 20 at the other end rises and falls. Then, while the positioning block 20 is rising and falling, it also slides on the outside of the second slide rail 17, so that the other part of the clamping frame 13 rises and falls. Positioning rod 18 drives another part of clamping frame 13 to move, and then all clamping frames 13 move and come into contact with the plate to clamp and fix the plate. After the plate is clamped and fixed, motor 7 is started. The output shaft of motor 7 rotates fixed plate 8. After fixed plate 8 rotates, support column 9 drives plate to tilt. After plate tilting, hot air blower 3 is started. Hot air blower 3 generates hot air, which enters the air outlet shell 4 and then the drying chamber 1. The hot air blows to the bottom inclined surface of plate to dry plate. During plate drying, some zinc plating liquid falls to the bottom of drying chamber 1, which collects zinc plating liquid. During drying, motor 7 makes fixed plate 8 rotate slowly to make hot air dry plate evenly. After one side of plate is dried, motor 7 can make fixed plate 8 flip plate and dry the other side of plate in the same way.
