Description

Technical Field

[0001] The utility model relates to the technical field of cooling galvanized aluminum-magnesium steel strips, in particular to a cooling device for hot-dip galvanized aluminum-magnesium steel strips. Background Art

[0002] Hot-dip aluminum-magnesium-zinc steel is a new type of highly corrosion-resistant coated steel plate. Its zinc coating is mainly composed of zinc. Due to the composite effect of these added elements, its corrosion inhibition effect is further improved. In addition, it has excellent processing performance under severe conditions, high coating hardness, and damage resistance. During processing and production, the device is usually at a high temperature, and the processed strip steel needs to be cooled. The common cooling method is usually air cooling or liquid cooling.

[0003] However, in actual use, the cooling effect of separate air cooling and water cooling is still relatively limited, so a device that can be easily used in combination is needed. At the same time, during spray cooling, the steam generated due to high temperature needs to be discharged in time to prevent the steam from flowing freely. The common method is to discharge it directly, which easily causes waste. The high-temperature liquid needs to be effectively collected and utilized. Utility Model Content

[0004] The utility model aims to provide a hot-dip galvanized aluminum-magnesium strip cooling device, which solves the existing problem that multiple methods are required for combined cooling and the high-temperature steam and liquid need to be collected and utilized.

[0006] A receiving groove is provided at the center of the fixed frame for receiving, and the tops of both sides of the fixed frame are fixedly connected to the top plate;

[0007] The centers of both sides of the air guide tube for guiding air are bent away from each other, and a plurality of fans are installed through one side of the two side walls of the air guide tube away from the fixed frame;

The interior of the closing plate is provided with a rectangular hole corresponding to the hot-dip galvanized aluminum-magnesium strip steel, and the bottom end of the rectangular hole is higher than the center of the support roller.

[0010] Preferably, a plurality of water outlet pipes are installed through the inner bottom end of one side of the fixed frame away from the air guide tube, and the top of the water outlet pipe is higher than the bottom of the outer wall of the support roller, and the bottom of the water outlet pipe is connected to the cooling pool through a conduit.

[0011] Preferably, the water inlet pipes at the top and bottom of the hot-dip galvanized aluminum-magnesium strip are penetrated by a plurality of sprinkler heads on one side close to the hot-dip galvanized aluminum-magnesium strip, and one end of the water inlet pipe penetrates the side wall of the fixed frame and is connected to the corresponding water pump through a conduit.

[0012] Preferably, a collecting pipe is provided through the center of one end of the top plate away from the air guide tube, and a through hole is provided around the bottom side wall of the collecting pipe.

The coolant is transported to the position of the water inlet pipe through the conduit, and then the liquid is sprayed out through the spray head to achieve cooling on both sides of the top and bottom of the hot-dip galvanized aluminum-magnesium strip. The liquid will flow to the inner bottom of the fixed frame and the air guide tube, and will be blocked by the closing plate to prevent the liquid from flowing out. At the same time, since the top of the water outlet pipe is higher than the bottom of the outer wall of the support roller, when there is more liquid, the liquid will contact the bottom of the support roller to achieve wetting of the support roller.

At the same time, it can also cool the high-temperature steam. At the same time, due to the blowing of the fan, it can effectively drive the air to move to one end of the collecting pipe. Since the hot-dip galvanized aluminum-magnesium strip moves to one end of the air guide tube through the fixed frame, the temperature near the end of the collecting pipe is higher. When the steam and external air move to one end of the collecting pipe, the temperature can be increased to avoid the temperature of the steam passing through the collecting pipe from decreasing. The liquid at the bottom of the fixed frame can also be collected and discharged through the outlet pipe for reuse. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 3 , Figure 4 As shown, the internal receiving groove of the fixed frame 1 is communicated with the interior of the air guide tube 2, and the ends of the fixed frame 1 and the air guide tube 2 away from each other are fixedly connected with a closing plate 301, and a rectangular hole corresponding to the hot-dip galvanized aluminum-magnesium strip steel 3 is opened inside the closing plate 301, and the bottom end of the rectangular hole is higher than the center of the support roller 5.

The bottom of the water outlet pipe 101 is connected to the cooling pool through a conduit. Since the top position of the water outlet pipe 101 is higher than the bottom of the outer wall of the support roller 5, when there is more liquid, the liquid will contact the bottom of the support roller 5 to achieve the wetting of the support roller 5. When the hot-dip galvanized aluminum-magnesium strip steel 3 moves, it will drive the support roller 5 to rotate, and the hot-dip galvanized aluminum-magnesium strip steel 3 is further cooled by the liquid on the outer wall of the support roller 5.

[0028] like Figure 4 , Figure 5 As shown, the top of the support roller 5 used for support is in contact with the bottom of the hot-dip galvanized aluminum-magnesium steel strip 3, and water inlet pipes 501 are arranged between the intervals of the multiple support rollers 5, and the water inlet pipes 501 are respectively located at the top and bottom of the hot-dip galvanized aluminum-magnesium steel strip 3. The water inlet pipes 501 at the top and bottom of the hot-dip galvanized aluminum-magnesium steel strip 3 are penetrated by a plurality of spray heads 502 on one side close to the hot-dip galvanized aluminum-magnesium steel strip 3. One end of the water inlet pipe 501 penetrates the side wall of the fixed frame 1 and is connected to the corresponding water pump through a conduit. The two ends of the support roller 5 are rotatably connected to the side wall of the receiving groove inside the fixed frame 1 through a rotating shaft, and the outer wall of the support roller 5 is provided with a plurality of arc grooves for containing liquid. The water pump is started to transport the coolant to the position of the water inlet pipe 501 through the conduit, and then the liquid is sprayed out through the spray head 502 to achieve spraying on both sides of the top and bottom of the hot-dip galvanized aluminum-magnesium steel strip 3 to achieve cooling.

The bottom of the top plate 4 is close to the collecting pipe 401 and is inclined toward the top in an arc shape. The top of the collecting pipe 401 is connected with the heat exchange cooling equipment through a conduit. The high-temperature steam moves to the top, reaches the collecting pipe 401 through the inclined top plate 4, and then passes through the through hole 402 to discharge the high-temperature steam, which is convenient for transporting it to the corresponding heat exchange equipment to utilize the remaining heat, and can also cool the high-temperature steam.

[0031] When in use, liquid is sprayed through the spray head 502 to spray both sides of the top and bottom of the hot-dip galvanized aluminum-magnesium steel strip 3 to achieve cooling. The liquid contacts the high-temperature hot-dip galvanized aluminum-magnesium steel strip 3 to generate high-temperature steam, and then the high-temperature steam moves to the top, reaches the collecting pipe 401 through the inclined top plate 4, and then passes through the through hole 402 to achieve the discharge of the high-temperature steam, which is convenient for transporting it to the corresponding heat exchange equipment to utilize the remaining heat, and can also achieve cooling of the high-temperature steam. At the same time, due to the blowing of the fan 201, it can effectively drive the air to move to one end of the collecting pipe 401.
