Description

Technical Field

[0001] This utility model relates to the field of galvanized steel strip processing technology, specifically a drying device for high-efficiency production of galvanized steel strip. Background Technology

[0002] Galvanized steel strip is made by coating long and narrow strips of cold-rolled or hot-rolled steel with a layer of material called zinc or aluminum to varying degrees.

[0003] Currently, some galvanized steel strip drying processes utilize rotary drum dryers. However, these dryers often result in the galvanized steel strip piling up, preventing even heat distribution and causing uneven drying. Furthermore, the moisture generated during drying is difficult to remove promptly, affecting the drying quality. Additionally, existing rotary drum dryers only dry the galvanized steel strip, requiring separate sorting after drying, increasing processing steps and reducing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-efficiency drying device for producing galvanized steel strip, solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a high-efficiency drying device for producing galvanized steel strip, comprising a base, two pulley supports on the top of the base, pulleys on the top of each pulley support, and a roller above the pulley supports. Two slide rails are provided on one outer wall of the roller, and the two slide rails are slidably connected to the two pulleys. A gear ring is provided on one outer wall of the roller near the two slide rails. A motor support is provided on the top of the base near the two pulley supports. A motor is fixedly connected to the top of the motor support by bolts. One end of the motor is rotatably connected to a gear via a rotating shaft. The gear meshes with the gear ring. Strip-shaped screening holes are opened on one outer wall of the roller, and an arc-shaped baffle is slidably connected inside the roller. A handle is provided on one outer wall of the arc-shaped baffle.

[0006] Preferably, a spiral stirring blade is provided on one inner wall of the drum, a through hole is provided on one outer wall of the spiral stirring blade, and an air outlet pipe is provided on one outer wall of the spiral stirring blade.

[0007] Preferably, a heating box is fixedly connected to the top of the base by bolts, and a fan and an electric heating tube are installed inside the heating box, with the fan located below the electric heating tube.

[0008] Preferably, an S-shaped tube is provided at the center of the interior of the heating box, and an air inlet grille is provided on one side of the outer wall of the heating box near the fan.

[0009] Preferably, one end of the S-shaped tube is provided with an air tube, and an air hole is provided on one side of the outer wall of the air tube.

[0010] Preferably, a slag collection box is provided at the top of the base near the lower part of the arc-shaped baffle.

[0011] This utility model has the following beneficial effects:

[0012] This high-efficiency drying device for producing galvanized steel strip uses a combination of a fan, S-shaped pipe, air pipe, and electric heating element to rapidly heat the air and blow it outwards from the center of the drum through the air pipe. This ensures that the galvanized steel strip is evenly exposed to hot air during the drying process, achieving uniform drying and improving processing quality.

[0013] 2. This high-efficiency drying device for producing galvanized steel strip, through the cooperation of strip-shaped screening holes, handles and arc-shaped baffles, enables the drum dryer to have sorting capabilities. It can sort galvanized steel strip according to size during the drying process, reducing subsequent sorting steps and improving the processing efficiency of galvanized steel strip.

[0014] 3. This high-efficiency drying device for producing galvanized steel strip uses the cooperation of spiral stirring blades, through holes and air outlet pipes to quickly and effectively discharge the moisture generated during the drying process of galvanized steel strip into the drum, avoiding the problem of the galvanized steel strip coming into contact with moisture and reducing drying efficiency due to collision with the hot air flow.

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

[0020] Please see Figure 1-3 A high-efficiency drying device for producing galvanized steel strip includes a base 1, two pulley supports 2 on the top of the base 1, pulleys 3 on the top of each pulley support 2, and a roller 4 above the pulley supports 2. Two slide rails 23 are provided on one outer wall of the roller 4, and the two slide rails 23 are slidably connected to the two pulleys 3. A gear ring 5 is provided on one outer wall of the roller 4 near the two slide rails 23. A motor support 6 is provided on the top of the base 1 near the two pulley supports 2. A motor 7 is fixedly connected to the top of the motor support 6 by bolts. One end of the motor 7 is rotatably connected to a gear 8 via a rotating shaft. The gear 8 meshes with the gear ring 5. A strip-shaped screening hole 9 is opened on one outer wall of the roller 4, and an arc-shaped baffle 11 is slidably connected inside the roller 4. A handle 10 is provided on one outer wall of the arc-shaped baffle 11.

[0021] Among them, a spiral stirring blade 12 is provided on one inner wall of the drum 4, a through hole 13 is provided on one outer wall of the spiral stirring blade 12, and an air outlet pipe 14 is provided on one outer wall of the spiral stirring blade 12.

[0022] The base 1 is fixedly connected to the top of the heating box 15 by bolts. The heating box 15 is equipped with a fan 16 and an electric heating tube 17. The fan 16 is located below the electric heating tube 17.

[0023] An S-shaped tube 18 is provided in the center of the heating box 15, and an air inlet grille 22 is provided on one side of the outer wall of the heating box 15 near the fan 16.

[0024] One end of the S-shaped tube 18 is provided with an air pipe 19, and an air hole 20 is opened on one side of the outer wall of the air pipe 19.

[0025] Among them, a slag collection box 21 is provided at the top of the base 1 near the lower part of the arc-shaped baffle 11.

[0026] During operation, the galvanized steel strip is first conveyed into the drum 4 via a conveyor belt. The motor 7 drives the gear 8 to rotate via a rotating shaft. The gear 8 meshes with the gear ring 5, which in turn drives the drum 4 to rotate. The pulley 3 slides through the slide rail 23, causing the drum 4 to rotate at an incline. The drum 4 drives the spiral stirring blade 12 to rotate, which dries the galvanized steel strip inside the drum 4. The fan 16 draws external air into the S-shaped pipe 18 through the air inlet grille 22. The electric heating tube 17 in the heating box 15 heats the air in the S-shaped pipe 18. The heated air enters the air pipe 19 and finally blows onto the dried galvanized steel strip through the air hole 20. The high-temperature air dries the galvanized steel strip. The air containing moisture enters the air outlet pipe 14 through the through hole 13 on the spiral stirring blade 12 and is finally discharged from the drum 4.
