Compared with other metal corrosion protection methods, the hot-dip galvanizing process has advantages in electrochemical protection of the coating, density of the coating, durability of the coating, maintenance-free coating, bonding strength between the coating and the substrate, and economy of the coating that are unmatched by other processes. Hot-dip galvanizing of steel pipes is widely used in national economic construction.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 9 As shown, the present invention provides a rapid cooling device for forming galvanized steel pipes, including a cooling box 1, an operating window 31 is provided on the top of the cooling box 1, a fixing plate 2 is fixedly connected to the inner wall of the cooling box 1, a sliding shaft 3 is fixedly connected to the bottom of the fixing plate 2, a supporting plate 6 is fixedly connected to the bottom of the sliding shaft 3, a positioning plate 4 is slidably connected to the outer wall of the sliding shaft 3, a placement groove is provided inside the positioning plate 4, a connecting rod 7 is fixedly connected to the bottom of the positioning plate 4, a placement table 8 is fixedly connected to the bottom of the connecting rod 7, an empty groove is provided inside the placement table 8, an exhaust fan 12 is fixedly connected to the top of the cooling box 1, an output end of the exhaust fan 12 is connected to an air inlet duct 13, one end of the air inlet duct 13 extends to the interior of the cooling box 1 and is fixedly connected to an air outlet nozzle 15, and a refrigeration box 14 is fixedly connected to the outer wall of the air inlet duct 13.

[0036] Through the above technical scheme, the hot-dip galvanized steel pipe is placed into the cooling box 1 through the operation window 31, and is placed on the placement table 8 through the placement slot. The hot-dip galvanized steel pipe is placed stably by cooperating with the placement slot through the positioning plate 4, and the exhaust fan 12 is started to draw the outside air into the cooling box 1 along the air inlet duct 13. The air entering the air inlet duct 13 is cooled by the refrigeration box 14, and the refrigerated cold air is sprayed into the cooling box 1 from the air outlet nozzle 15 to cool the hot-dip galvanized steel pipe.

[0037] Two guide plates 17 are symmetrically fixedly connected to the top of the inner wall of the cooling box 1. Both guide plates 17 are arranged in an arc shape. A plurality of guide blocks 18 are equidistantly fixedly connected to the top of the guide plates 17. Both sides of the fixed plate 2 are arranged in an arc shape. A plurality of guide grooves 16 are equidistantly provided on the top of the fixed plate 2.

[0038] Through the above technical solution, the air outlet nozzle 15 sprays cold air to the guide groove 16 on the fixed plate 2. Due to the high density of the cold air, the cold air flows downward along the arc surface of the side of the fixed plate 2. With the help of the arc-shaped guide plate 17 and the guide block 18, the cold air is divided into multiple streams and then flows downward, so that the cold air can be accurately poured into the hot-dip galvanized steel pipe. In this way, the cold air can pass through the inside of the hot-dip galvanized steel pipe, and the excess cold air flows downward along the outside of the hot-dip galvanized steel pipe. This kind of synchronous cooling method inside and outside improves the cooling efficiency of the hot-dip galvanized steel pipe.

[0039] The inner wall of the cooling box 1 is symmetrically fixedly connected with two side panels 19 , the bottom of the two side panels 19 is fixedly connected with a first arc plate 20 , the inside of the two side panels 19 is fixedly connected with a second arc plate 21 , and the top of the two side panels 19 is fixedly connected with a third arc plate 22 .

[0040] Through the above technical scheme, the two third curved plates 22 cooperate with the two side plates 19 to concentrate the cold air flowing downward to the middle, so that the cold air can better fit the outside of the hot-dip galvanized steel pipe, thereby improving the cooling effect on the outside of the hot-dip galvanized steel pipe. The cold air flowing downward along the side plate 19 enters the second curved plate 21, and flows upward along the concave surface of the second curved plate 21 to prevent the cold air from settling too quickly, thereby extending the cooling time of the middle position of the hot-dip galvanized steel pipe. The cold air passing through the second curved plate 21 flows into the first curved plate 20, and flows upward along the concave surface of the first curved plate 20 and passes through the empty groove, thereby extending the cooling time of the bottom position of the hot-dip galvanized steel pipe.

[0041] A water pump 25 is fixedly connected to the outer wall of the cooling box 1, and a water pumping pipe 26 is connected to the output end of the water pump 25. One end of the water pumping pipe 26 extends to the interior of the cooling box 1, and the other end of the water pumping pipe 26 is connected to two connecting pipes 27. The inner wall of the cooling box 1 is symmetrically connected to two water outlet pipes 23. The outer walls of the two water outlet pipes 23 are both provided with nozzles 24. One end of the water outlet pipe 23 passes through the cooling box 1 and is rotatably connected to the connecting pipe 27. The outer wall of the cooling box 1 is provided with a driving component used in conjunction with the water outlet pipe 23, and a water outlet trough 28 is opened inside the first curved plate 20.

[0042] Through the above technical scheme, water is filled into the bottom of the cooling box 1, and the water pump 25 is started to pump water along the pumping pipe 26, the connecting pipe 27, and the water outlet pipe 23 to the nozzle 24, and the water is sprayed onto the hot-dip galvanized steel pipe through the nozzle 24 to further cool the hot-dip galvanized steel pipe. By controlling the driving component, the water outlet pipe 23 is rotated to drive the nozzle 24 to swing downward, thereby spraying different positions of the hot-dip galvanized steel pipe. When the nozzle 24 rotates to the highest angle, water is sprayed into the inside of the hot-dip galvanized steel pipe to enhance the cooling effect of the hot-dip galvanized steel pipe. The sprayed water falls on the inner concave surface of the first curved plate 20. At this time, the temperature of the water that has contacted the hot-dip galvanized steel pipe increases, and with the settlement of the cold air above, the water in the first curved plate 20 is cooled. As the water in the first curved plate 20 gradually increases, it is discharged from the water outlet trough 28 and accumulated again at the bottom of the cooling box 1 for easy recycling.

[0043] The tops of the positioning plate 4 and the placement table 8 are both set as inclined surfaces. A support rod 9 is fixedly connected to the top of the placement table 8 and directly below the placement groove. A support block 10 is fixedly connected to the top of the support rod 9. The support block 10 is truncated cone-shaped, and a plurality of extension plates 11 are fixedly connected to the outer wall of the support block 10 at equal intervals.

[0044] Through the above technical solution, the top of the positioning plate 4 and the placing table 8 are set as an inclined surface, so that the water on the top of the positioning plate 4 and the placing table 8 can be drained as soon as possible, and the falling water is guided to slide into the first arc plate 20. The hot-dip galvanized steel pipe is inserted into the support block 10 to support the hot-dip galvanized steel pipe. By setting the extension plate 11, a gap is left between the inner wall of the hot-dip galvanized steel pipe and the support block 10, which is convenient for draining the water inside the hot-dip galvanized steel pipe.

[0045] The outer wall of the cooling box 1 is fixedly connected to a first mounting plate 32, the top of the first mounting plate 32 is fixedly connected to a motor 33, the output end of the motor 33 is fixedly connected to a rotating shaft 34, one end of the rotating shaft 34 extends to the interior of the cooling box 1 and is fixedly connected to a half gear 35, the bottom of the placement table 8 is fixedly connected to a first rack 36, the half gear 35 is meshed with the first rack 36, and the outer wall of the sliding shaft 3 is sleeved with a spring 5.

[0046] Through the above technical scheme, after the hot-dip galvanized steel pipe is cooled, the nozzle 24 is closed, the motor 33 is started, the rotating shaft 34 is driven to rotate, and the half gear 35 is rotated. When the toothed side of the half gear 35 is meshed with the first rack 36, the first rack 36 is driven to move upward, so that the placement table 8 moves upward, and the hot-dip galvanized steel pipe moves upward. The connecting rod 7 also moves upward, drives the positioning plate 4 to move upward, and compresses the spring 5. When the toothless side of the half gear 35 contacts the first rack 36, under the action of the spring 5, the positioning plate 4, the connecting rod 7, the placement table 8, and the hot-dip galvanized steel pipe move downward as a whole, and stop moving downward when the positioning plate 4 contacts the top of the support plate 6. In this reciprocating manner, the hot-dip galvanized steel pipe continues to vibrate downward, which is convenient for shaking off the water inside and outside the hot-dip galvanized steel pipe, eliminating the need for subsequent operators to wipe, and improving the efficiency of the hot-dip galvanized steel pipe cooling operation.

[0047] The driving assembly includes a slide plate 40, which is mounted on the outer wall of the cooling box 1 and is slidably connected to the cooling box 1. Two second racks 41 are symmetrically fixedly connected to the bottom of the slide plate 40. The other ends of the two water outlet pipes 23 both penetrate the cooling box 1 and are fixedly connected to a spur gear 39. The two spur gears 39 are respectively meshed with the two second racks 41. A second mounting plate 37 is fixedly connected to the outer wall of the cooling box 1. A reciprocating screw 38 is rotatably connected to the inner wall of the second mounting plate 37. The reciprocating screw 38 is connected to the slide plate 40 through a screw nut pair. The output end of the motor 33 is fixedly connected to a first bevel gear 44. The bottom of the reciprocating screw 38 is fixedly connected to a second bevel gear 45. The first bevel gear 44 is meshed with the second bevel gear 45.

[0048] Through the above technical solution, after the motor 33 is started, it drives the first bevel gear 44 to rotate, which makes the second bevel gear 45 rotate, drives the reciprocating screw rod 38 to rotate, makes the slide plate 40 move back and forth up and down, drives the two second racks 41 to move back and forth up and down, makes the two spur gears 39 reciprocate forward and reverse, drives the two water outlet pipes 23 to rotate back and forth forward and reverse, makes the two nozzles 24 swing up and down, and sprays water to cool the hot-dip galvanized steel pipe at different positions.

[0049] A V-shaped plate 42 is fixedly connected to the inner wall of the cooling box 1 and is located between the two side plates 19 , and a lower water tank 43 is provided at the bottom of the V-shaped plate 42 .

[0050] Through the above technical solution, the V-shaped plate 42 is set to block the cold air that sinks downward from the middle position of the cooling box 1 to prevent the cold air from sinking too quickly. The lower water tank 43 is set to drain the water that falls on the V-shaped plate 42.

[0051] Specifically, a guide plate 29 is fixedly connected inside the cooling box 1 and below the first arc-shaped plate 20 . The guide plate 29 is installed obliquely, and a plurality of triangular protrusions 30 are fixedly connected to the top of the guide plate 29 at equal intervals.

[0052] Through the above technical solution, the water flowing out from the water outlet trough 28 falls on the guide plate 29 and flows along the inclined surface of the guide plate 29. The water can cool itself during the circulation process to prevent the water temperature from rising after contacting the hot-dip galvanized steel pipe and affecting the subsequent water spraying and cooling effect. The triangular protrusion 30 can extend the water flowing time on the guide plate 29, giving the water enough time to cool itself. The water sliding down from the guide plate 29 is accumulated at the bottom of the cooling box 1 for easy recycling.

[0053] A method for rapidly cooling equipment for forming a galvanized steel pipe comprises the following steps:

[0054] S1: Place the hot-dip galvanized steel pipe into the cooling box 1 through the operation window 31, and place it on the placement table 8 through the placement slot;

[0055] S2: inject cold air into the cooling box 1 to cool the hot-dip galvanized steel pipe, fill water into the cooling box 1, start the nozzle 24 to spray water on the hot-dip galvanized steel pipe, start the motor 33 to drive the nozzle 24 to swing up and down, and adjust the position of the water spraying;

[0056] S3: close the nozzle 24, start the motor 33 to drive the positioning plate 4, the connecting rod 7, the placement table 8, and the hot-dip galvanized steel pipe to move upward as a whole and then fall downward, so that the hot-dip galvanized steel pipe continues to vibrate downward.

[0057] When in use, the hot-dip galvanized steel pipe is placed into the cooling box 1 through the operation window 31, and is placed on the placement table 8 through the placement slot, and the hot-dip galvanized steel pipe is inserted into the support block 10, and the hot-dip galvanized steel pipe is supported. A gap is left between the inner wall of the hot-dip galvanized steel pipe and the support block 10 through the provided extension plate 11, so as to facilitate the discharge of water inside the hot-dip galvanized steel pipe. The hot-dip galvanized steel pipe is placed stably through the positioning plate 4 and the placement slot, and the exhaust fan 12 is started to draw the outside air into the cooling box 1 along the air inlet duct 13, and the air entering the air inlet duct 13 is cooled by the refrigeration box 14, and the refrigerated cold air is sprayed into the cooling box 1 from the air outlet nozzle 15 to cool the hot-dip galvanized steel pipe, and the air outlet The nozzle 15 sprays the cold air to the guide groove 16 on the fixed plate 2. Since the density of the cold air is greater than that of the air, the cold air flows downward along the arc surface of the side of the fixed plate 2. The arc-shaped guide plate 17 and the guide block 18 are used to divide the cold air into multiple streams and then flow downward, so that the cold air can be accurately poured onto the hot-dip galvanized steel pipe. Thus, the cold air can pass through the inside of the hot-dip galvanized steel pipe, and the excess cold air flows downward along the outside of the hot-dip galvanized steel pipe. This internal and external synchronous cooling method can improve the cooling efficiency of the hot-dip galvanized steel pipe. By setting two third arc plates 22 and cooperating with two side plates 19, the cold air flowing downward is concentrated in the middle, so that the cold air can better fit the outside of the hot-dip galvanized steel pipe. Improve the cooling effect on the outside of the hot-dip galvanized steel pipe. The cold air flowing downward along the side plate 19 enters the second curved plate 21 and flows upward along the concave surface of the second curved plate 21 to prevent the cold air from settling too quickly, thereby extending the cooling time of the middle position of the hot-dip galvanized steel pipe. The cold air passing through the second curved plate 21 flows into the first curved plate 20, flows upward along the concave surface of the first curved plate 20 and passes through the empty groove, thereby extending the cooling time of the bottom position of the hot-dip galvanized steel pipe. The V-shaped plate 42 blocks the cold air that settles downward in the middle position of the cooling box 1 to prevent the cold air from settling too quickly. Water is filled in the bottom of the cooling box 1, and the water pump 25 is started to pump water along the pumping pipe 26, The connecting pipe 27 and the water outlet pipe 23 are pumped to the nozzle 24, and water is sprayed onto the hot-dip galvanized steel pipe through the nozzle 24 to further cool the hot-dip galvanized steel pipe. The starting motor 33 drives the first bevel gear 44 to rotate, so that the second bevel gear 45 rotates, and the reciprocating screw rod 38 rotates, so that the slide plate 40 moves up and down reciprocatingly, and the two second racks 41 move up and down reciprocatingly, so that the two spur gears 39 rotate forward and reversely reciprocatingly, and the two water outlet pipes 23 rotate forward and reversely reciprocatingly, so that the two nozzles 24 swing up and down, and spray water to cool different positions of the hot-dip galvanized steel pipe. When the nozzle 24 rotates to the highest angle, water is sprayed to the inside of the hot-dip galvanized steel pipe to improve the cooling effect of the hot-dip galvanized steel pipe.The positioning plate 4 and the top of the placing table 8 are set as inclined surfaces, so that the water on the top of the positioning plate 4 and the placing table 8 can be drained as soon as possible, and the falling water can be guided to slide into the first curved plate 20. The water falls on the inner concave surface of the first curved plate 20. At this time, the temperature of the water that has contacted the hot-dip galvanized steel pipe increases. With the sedimentation of the cold air above, the water in the first curved plate 20 can be cooled. As the water in the first curved plate 20 gradually increases, it is discharged from the water outlet trough 28 and accumulated again at the bottom of the cooling box 1 for easy recycling; the water flowing out of the water outlet trough 28 falls on the guide plate 29 and flows along the inclined surface of the guide plate 29. During the circulation process, the water can cool itself, preventing the water temperature from rising after contacting the hot-dip galvanized steel pipe and affecting the effect of subsequent water spraying and cooling; the triangular protrusion 30 prolongs the water flowing time on the guide plate 29, giving the water enough self-cooling time, and the water sliding off the guide plate 29 The water is stored at the bottom of the cooling box 1 for easy recycling; after the hot-dip galvanized steel pipe is cooled, the nozzle 24 is closed and the motor 33 is started, which drives the rotating shaft 34 to rotate, so that the half gear 35 rotates. When the toothed side of the half gear 35 meshes with the first rack 36, the first rack 36 is driven to move upward, so that the placement table 8 moves upward, the hot-dip galvanized steel pipe moves upward, the connecting rod 7 moves upward, the positioning plate 4 moves upward, and the spring 5 is compressed; when the toothless side of the half gear 35 contacts the first rack 36, the positioning plate 4, the connecting rod 7, the placement table 8, and the hot-dip galvanized steel pipe move downward as a whole under the action of the spring 5, and the positioning plate 4, the connecting rod 7, the placement table 8, and the hot-dip galvanized steel pipe stop moving downward when the positioning plate 4 contacts the top of the support plate 6. Thus, the hot-dip galvanized steel pipe continues to vibrate downward, which is convenient for shaking off the water inside and outside the hot-dip galvanized steel pipe, eliminating the need for subsequent operators to wipe, and improving the efficiency of the hot-dip galvanized steel pipe cooling operation. ;
