Description

Technical Field

[0001] This utility model belongs to the field of strip steel production technology, specifically relating to a multi-stage drying and conveying line for galvanized strip steel. Background Technology

[0002] In the strip galvanizing production process, the drying process is a crucial step in ensuring product quality. Traditional strip galvanizing drying conveyor lines have revealed numerous drawbacks in practical applications. After galvanizing and cooling, a large amount of moisture adheres to the surface of the strip. If this moisture is not removed promptly and efficiently, it not only prolongs the overall drying time and reduces production efficiency but may also cause localized corrosion or quality defects in the galvanized layer due to residual moisture. Some traditional equipment relies on only a single drying method, such as simple hot air drying, which fails to pre-treat the moisture on the strip surface before drying. This necessitates prolonged and energy-intensive operation of the drying equipment, increasing production costs. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a multi-stage drying and conveying line for galvanized steel strip, thereby solving the problem of low efficiency in traditional steel strip drying.

[0004] To achieve the above objectives, a conveying assembly is included. The conveying assembly includes a base frame and a conveying frame. A positioning assembly is installed on the top of the conveying assembly. The positioning assembly includes a mounting sleeve, a sliding rod, a limiting plate, and a cross plate. The positioning assembly limits the conveying position of the galvanized steel ring. The positioning assemblies are distributed on both sides of the conveying frame. A top plate is installed above the positioning assemblies. The top plate is located above the positioning assemblies. A drainage assembly is provided below the top plate. Three sets of drainage assemblies are supported below the top plate. The drainage assembly includes a fixing pipe, an adjusting rod, a fixing ring, and an L-shaped rod. Four L-shaped rods are equidistantly distributed on the fixing ring. The positions of each set of L-shaped rods are staggered. The top plate has clearance holes that match the top of the L-shaped rods.

[0005] Preferably, the mounting sleeve is installed on both sides of the conveyor frame, the slide rod is slidably connected to the mounting sleeve, a vertical plate is detachably connected to the limiting plate, and one side of the horizontal plate is connected to the vertical plate.

[0006] Preferably, the slide rod has a plurality of equally spaced insertion holes, and the mounting sleeve has a pin for limiting the position of the insertion holes. The limiting plate is connected to the slide rod through a support head.

[0007] Preferably, one end of the adjusting rod is connected to the fixed tube, and the fixed tubes are connected to each other through a connecting tube.

[0008] Preferably, the top plate is connected to the conveyor frame by a telescopic rod, and the top plate is connected to the fixed ring by an installation hanger.

[0009] Preferably, a connecting ring is installed at one end of the L-shaped rod, and the bottom of the adjusting rod is connected to the connecting ring.

[0010] This utility model has the following beneficial effects:

[0011] 1. The positioning components on both sides allow for flexible adjustment of the limiting distance, accommodating galvanized steel coils of different diameters. This ensures the coil remains centered during transport, aligning with the drainage components. Three drainage components are distributed on the top plate. The L-shaped rods installed on the fixing rings are staggered, and the L-shaped rods allow for adjustment of the bottom position of the adjusting rods. This enables the adjusting rods to perform multi-angle, all-around airflow sweeping on the surface of the galvanized steel coils, quickly removing most of the residual moisture. This lays the foundation for subsequent drying processes, significantly shortening the overall drying time and improving production efficiency. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0018] Example 1:

[0019] like Figure 1As shown in Figure 4, this utility model provides the following technical solution: it includes a conveying assembly 1, which includes a base frame 11 and a conveying frame 12. A positioning assembly 2 is installed on the top of the conveying assembly 1. The positioning assembly 2 includes an mounting sleeve 21, a sliding rod 22, a limiting plate 23, and a horizontal plate 24. The positioning assembly 2 limits the conveying position of the galvanized steel ring. The positioning assembly 2 is distributed on both sides of the conveying frame 12. A top plate 3 is installed above the positioning assembly 2. The top plate 3 is located above the positioning assembly 2. A drain assembly 4 is provided below the top plate 3. Three sets of drain assemblies 4 are supported below the top plate 3. The drain assembly 4 includes a fixed pipe 41, an adjusting rod 42, a fixing ring 43, and an L-shaped rod 44. The four L-shaped rods 44 are equidistantly distributed on the fixing ring 43. The positions of each set of L-shaped rods 44 are staggered. The top plate 3 is provided with a clearance hole 31 that matches the top of the L-shaped rod 44.

[0020] In this implementation scheme: the conveying assembly 1 serves as the carrier of the supporting device. During use, the conveying assembly 1 consists of a base frame 11 and a conveying frame 12. The conveying frame 12 is positioned at the top of the conveyor belt. Positioning components 2 are installed on the conveying frames 12 on both sides, allowing the galvanized steel coil to be supported on the conveyor belt. The positioning components 2 are located on both sides of the steel coil and can slide on the mounting sleeve 21 via the sliding rod 22. The limiting plate 23 installed at one end of the sliding rod 22 can push the position of the horizontal plates 24, allowing the spacing between the two horizontal plates 24 to be adjusted so that the spacing between the horizontal plates 24 aligns with the galvanized steel coil. The zinc coil diameter is matched to the size of the strip galvanized steel coil, so that when it is conveyed on the conveyor assembly 1, it can be limited by the positioning assembly 2, so that it is limited to the center position on the conveyor belt of the conveyor assembly 1, thereby aligning it with the upper drain assembly 4. At this time, it can be supported above the positioning assembly 2 by the top plate 3. The height of the top plate 3 can be adjusted by the height of the support rod. After the height of the top plate 3 is properly adjusted, it is supported below the drain assembly 4. The drain assembly 4 consists of a fixed pipe 41, an adjusting rod 42, a fixing ring 43 and an L-shaped rod 44. The L-shaped rod 44 slides on the... The outer wall of the fixing ring 43 allows the bottom position of the adjusting rod 42 to be limited at one end. The bottom of the adjusting rod 42 serves as an air outlet. Based on the size of the strip coil, the four equidistant adjusting rods 42 can correspond to the outer wall of the strip coil, ensuring the galvanized strip coil is conveyed to the area below the drainage assembly 4. At this point, the adjusting rods 42 are connected to the fixed pipes 41, which are connected by a connecting pipe 32. With the three drainage assemblies 4 distributed on the top plate 3, the L-shaped rods 44 installed on each drainage assembly 4 are at different angles, allowing the galvanized strip coil to be conveyed to the area below the drainage assembly 4. The wall can be subjected to the air pressure of the air outlet of the regulating rod 42, so that the outer wall of the galvanized steel strip coil is cooled and galvanized. The water adhering to it after cooling can be quickly separated from it by the drain component 4. The water that is difficult to separate can be continuously transported by the drain component 4 to the drying channel for drying treatment of the galvanized steel strip coil. Thus, the device can first remove most of the adhering water residue by the drain component 4 during the drying process, and then carry out enhanced drying treatment in conjunction with the high temperature drying channel. This allows the device to perform multi-stage drying treatment on the strip steel and significantly improve its drying efficiency.

[0021] Mounting sleeves 21 are installed on both sides of the conveyor frame 12. Sliding rods 22 are slidably connected to mounting sleeves 21. Vertical plates 25 are detachably connected to limiting plates 23. One side of horizontal plates 24 is connected to vertical plates 25. Mounting sleeves 21 are installed on both sides of the conveyor frame 12, positioning them on both sides of the conveyor belt. This allows horizontal plates 24 to limit the position of the strip steel on both sides, enabling it to be transported at the center of the conveyor belt. Vertical plates 25 are used to support horizontal plates 24, allowing them to be stably positioned on limiting plates 23 and limiting the position of the strip steel.

[0022] The slide rod 22 has several equally spaced insertion holes 221. The mounting sleeve 21 has pins 211 inserted to limit the position of the insertion holes 221. The limiting plate 23 is connected to the slide rod 22 via a support head 222. The insertion holes 221 on the slide rod 22 can be connected to the pins 211 installed on the mounting sleeve 21, so that the insertion holes 221 at different positions can correspond to the pins 211. This allows the position of the slide rod 22 on the mounting sleeve 21 to be adjusted and limited, thereby adjusting the spacing between the horizontal plates 24. The support head 222 is used to connect the limiting plate 23 to one end of the slide rod 22.

[0023] One end of the adjusting rod 42 is connected to the fixed pipe 41, and the fixed pipes 41 are connected to each other through the connecting pipe 32. After the connecting pipe 32 and the fixed pipe 41 are connected, the air can be transmitted to the connecting pipe 32 by connecting the fan, and then diverted to the fixed pipe 41. After that, the air is applied to the outer wall of the strip steel by the adjusting rod 42 to initially remove the moisture from the outer wall of the strip steel.

[0024] The top plate 3 is connected to the conveyor frame 12 by a telescopic rod, and the top plate 3 is connected to the fixing ring 43 by an installation hanger. The top plate 3 and the conveyor frame 12 are connected by a telescopic rod, so that the top plate 3 can be adjusted according to the strip size to ensure that the drain assembly 4 is above the strip and avoid affecting the displacement of the strip. At the same time, the fixing ring 43 is fixed by a hanger to keep it stable in the position below the top plate 3.

[0025] One end of the L-shaped rod 44 is equipped with a connecting ring 45, and the bottom of the adjusting rod 42 is connected to the connecting ring 45. The connecting ring 45 is used to limit the bottom of the adjusting rod 42, so that after the connecting ring 45 is displaced, the bottom position of the adjusting rod 42 can be dragged to move. The adjusting rod 42 is a flexible tube, which makes it easy to adjust the bottom position.

[0026] The working principle of this technical solution is as follows: Based on the diameter of the galvanized steel strip to be processed, adjust the position of the positioning component 2: slide the sliding rods 22 on both sides so that the insertion holes 221 on them correspond to and are fixed with the pins 211 on the mounting sleeve 21, thereby determining the spacing between the horizontal plates 24; adjust the distance between the top plate 3 and the conveyor frame 12 using the telescopic rod to position the draining component 4 at a suitable height above the galvanized steel strip; use the hanging rod to fix the position of the fixing ring 43 to ensure that the adjusting rod 42 can be aligned with the surface of the galvanized steel strip; and adjust the position of the galvanized steel strip according to the diameter of the galvanized steel strip. The width of the coil and the position of the sliding L-shaped rod 44 on the fixed ring 43 are adjusted so that the four adjusting rods 42 are evenly distributed and correspond to the outer wall of the galvanized steel coil. At the same time, the adjusting rods 42 of the three sets of drainage components 4 are in a staggered state. When the galvanized steel coil reaches below the drainage component 4, the air circuit system is activated. The air enters the fixed pipe 41 through the connecting pipe 32 and is then blown onto the surface of the galvanized steel coil through the adjusting rod 42 to initially remove the residual moisture. The pre-dried galvanized steel coil is then conveyed to the drying channel for further processing.
