Description

Technical Field

[0001] This utility model mainly relates to the technical field of galvanizing, specifically a cooling device for galvanizing metal products. Background Technology

[0002] Hot-dip galvanizing involves immersing the metal workpiece in molten zinc. Under certain time and temperature conditions, zinc undergoes a series of physicochemical reactions with the metal surface, forming a coating layer composed of zinc and zinc-iron alloy on the workpiece surface. This coating layer effectively isolates the metal from external corrosive media, thus playing a role in corrosion prevention. However, this process causes the temperature of the metal parts to rise, so cooling devices are needed to reduce the temperature of the metal parts to prevent the performance of the metal parts from being affected or to cause safety hazards due to excessive temperature.

[0003] An existing cooling device for hot-dip galvanized steel pipe processing has a roller conveyor belt fixedly connected to the top of a water tank, a base fixedly connected to the bottom of the water tank, a water pump fixedly connected to the top of the base, an inlet pipe fixedly connected to the input end of the water pump, an outlet pipe fixedly connected to the output end of the water pump, an atomizing nozzle fixedly connected to the bottom of the connecting pipe, a gantry fixedly connected to the top of the base, a fan fixedly connected to the bottom of the gantry, and heat dissipation fins fixedly connected to the bottom of the fan.

[0004] Existing cooling devices use unidirectional spraying, which does not provide comprehensive coverage. Uneven cooling after hot-dip galvanizing of metal parts can lead to problems such as coating cracking, peeling, workpiece deformation, and surface oxidation color differences. Therefore, a cooling device that can cool multiple surfaces of the workpiece simultaneously is needed to reduce the adverse effects of temperature differences on the coating. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a cooling device for galvanizing metal products, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a cooling device for galvanizing metal products, including a base, a water tank at the bottom of the base, a water pump connected to the outlet of the water tank via a pipe, and a spray assembly connected to the outlet of the water pump via a water supply pipe; the spray assembly includes multiple upper and lower spray guns fixed within the base, the upper spray guns being mounted above the base via a crossbeam with their nozzles facing downwards, and the lower spray guns being mounted on the base platform with their nozzles facing upwards; both the upper and lower spray guns employ atomizing nozzles. In this preferred embodiment, the upper and lower spray guns cooperate to increase the contact area between the coolant and the metal parts, accelerating heat exchange.

[0007] Preferably, a fan is provided on one side of the upper spray gun, and a heat sink is fixed at the bottom of the fan. The heat sink has a multi-layer fin structure, and the water supply pipe passes through the inside of the heat sink. In this preferred embodiment, the water supply pipe passes through the heat sink, and together with the fan, the heat dissipation is accelerated, pre-cooling the coolant. This results in a lower coolant temperature and greater stability during spraying, thus enhancing the cooling effect.

[0008] Preferably, the base is provided with symmetrical support plates on both sides, and the support plates are provided with a clamping assembly on the side facing the center of the base. The clamping assembly includes an arc-shaped clamp, a telescopic cylinder and a mounting base. The telescopic cylinder is fixed to the support plate by the mounting base, and the arc-shaped clamp is provided at the output end of the telescopic cylinder.

[0009] Preferably, the inner side of the arc-shaped clamp is provided with a drainage groove on the contact surface between the clamp and the metal part, and a high-temperature resistant anti-slip pad is provided. In this preferred embodiment, the drainage groove on the inner side of the clamp prevents coolant from accumulating and affecting clamping, and the anti-slip pad enhances friction and avoids displacement or collision of the metal part during the cooling process.

[0010] Preferably, the base is provided with symmetrical horizontal guide rails on both sides, and a slider is slidably connected in the guide rail. The sliders on both sides are connected and fixed by a horizontal bracket, and a shelf is provided on the bracket.

[0011] Preferably, the base has symmetrical transmission mechanisms on both sides of the lower spray gun on the support platform. Each transmission mechanism includes a drive wheel, a driven wheel, and a transmission belt. The drive wheel and driven wheel are fixed to both sides of the base through bearing seats. The transmission belt is sleeved on the drive wheel and driven wheel and is fixedly connected to the bracket. A drive motor is provided on one side of the base platform. The output shaft of the drive motor is connected to the drive wheel. In this preferred embodiment, the transverse guide rail, slider, and transmission mechanism work together, and the drive motor precisely controls the movement of the bracket and the platform, smoothly conveying the metal parts through the cooling zone.

[0012] Preferably, the base has a connecting port at the bottom, the connecting port has a detachable filter screen and a guide plate, the water tank has an opening at the top that matches the connecting port, the base has multiple support columns at the bottom, and the support columns have anti-slip pads on their contact surfaces with the ground. In this preferred embodiment, the base connecting port is equipped with a metal woven filter screen and a guide plate. The filter screen intercepts impurities, the guide plate guides the backflow, and the coolant is circulated through the water tank and water pump. The support columns are equipped with rubber anti-slip pads to enhance the stability of the base.

[0013] In summary, the present invention has the following main advantages: The upper and lower spray guns work together, with atomizing nozzles increasing the contact area between the coolant and the metal parts, forming a three-dimensional cooling zone with opposing upper and lower sprays, eliminating cooling dead zones. Compared to traditional single spraying, the cooling is more uniform, reducing cracks in the coating caused by temperature differences and improving the surface quality of galvanized metal parts. The water pipe passes through heat sinks, combined with a fan to accelerate heat dissipation and pre-cool the coolant. This results in a lower and more stable coolant temperature during spraying, enhancing the cooling effect. Drainage grooves inside the clamp prevent coolant buildup from affecting clamping, and anti-slip pads increase friction to prevent metal parts from shifting or bumping during cooling. The transverse guide rail, slider, and transmission mechanism work together, with the drive motor precisely controlling the movement of the support and platform, smoothly conveying the metal parts through the cooling zone. The base connection port is equipped with a metal woven filter and a guide plate. The filter intercepts impurities, and the guide plate guides the return flow. The coolant is circulated through a water tank and pump. The support columns are equipped with rubber anti-slip pads to enhance the stability of the base. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The embodiments of this utility model will be described below based on its overall structure.

[0018] like Figure 1 and 2As shown, a cooling device for galvanizing metal products includes a base 10, a water tank 20 at the bottom of the base 10, a connecting port 13 at the bottom of the base 10, a removable filter screen and a guide plate at the connecting port 13, and an opening at the top of the water tank 20 that matches the connecting port 13. The water outlet of the water tank 20 is connected to a water pump 21 via a pipe, and the water outlet of the water pump 21 is connected to a spray assembly 22. The spray assembly 22 includes multiple upper spray guns 221 and lower spray guns 222 fixed inside the base 10. The upper spray guns 221 are mounted above the base 10 via a crossbeam 12 with their nozzles facing downwards, and the lower spray guns 222 are mounted on the platform of the base 10 with their nozzles facing upwards. Both the upper spray guns 221 and lower spray guns 222 use atomizing nozzles. A fan 25 is provided on one side, and a heat sink 26 is fixed at the bottom of the fan 25. The heat sink 26 has a multi-layer fin structure. The water supply pipe 23 passes through the inside of the heat sink 26. The water tank 20 stores cooling water. After the water pump 21 is started, it draws cooling water through the pipe and delivers it to the spray assembly 22. When the water supply pipe 23 passes through the heat sink 26, the fan 25 blows air through the multi-layer fin heat sink 26 to pre-cool the cooling water in the water supply pipe 23. The upper spray gun 221 and the lower spray gun 222 receive the pre-cooled cooling water and convert it into fine droplets through the atomizing nozzle. The nozzle of the upper spray gun 221 faces downward and the nozzle of the lower spray gun 222 faces upward, forming a three-dimensional spray area that sprays upward and downward, covering the surface of the metal part in all directions. The cooling water after the cooling process flows back through the bottom connection port 13 of the base 10. The deflector guides the flow to the water tank 20. During the process, the removable filter screen intercepts impurities to avoid clogging the pipes and nozzles. The filtered cooling water is stored in the water tank 20 and can be drawn again by the water pump 21 to participate in the cooling cycle. like Figure 1 and 3 The base 10 has multiple support columns 14 at its bottom, and the contact surface between the support columns 14 and the ground is provided with anti-slip pads. Support plates 11 are symmetrically arranged on both sides of the base 10. A clamping assembly 24 is provided on the side of the support plate 11 facing the center of the base 10. The clamping assembly 24 includes an arc-shaped clamp 241, a telescopic cylinder 242, and a mounting base 243. The telescopic cylinder 242 is fixed on the support plate 11 through the mounting base 243. The arc-shaped clamp 241 is located at the output end of the telescopic cylinder 242. The inner side of the arc-shaped clamp 241 has a drainage groove on the contact surface with the metal part and is provided with a high-temperature resistant anti-slip pad. When the metal part reaches the designated position, the telescopic cylinder 242 is activated, pushing the arc-shaped clamp 241 closer to the metal part. The arc-shaped clamp 241 adapts to the contour of the metal part. The inner drainage groove drains away the surface coolant, and the high-temperature resistant anti-slip pad increases the friction, thereby achieving stable and flexible clamping of the metal part and preventing the workpiece from shifting during the cooling process. like Figure 4 and 5As shown, the base 10 has symmetrically arranged transverse guide rails 30 on both sides. Sliding sliders 31 are slidably connected within the guide rails 30. The sliders 31 on both sides are connected and fixed by horizontal supports 32. A platform 33 is provided on the support platform of the base 10. Transmission mechanisms 34 are symmetrically arranged on both sides of the lower spray gun 222 on the support platform of the base 10. Each transmission mechanism 34 includes a driving wheel 341, a driven wheel 342, and a transmission belt 343. The driving wheel 341 and driven wheel 342 are fixed to both sides of the base 10 by bearing seats. The transmission belt 343... The drive belt 343 is fixedly connected to the bracket 32 ​​and mounted on the drive wheel 341 and driven wheel 342. A drive motor 35 is provided on one side of the platform of the base 10. The output shaft of the drive motor 35 is connected to the drive wheel 341. When the drive motor 35 runs, it drives the drive wheel 341 to rotate. The drive belt 343 is linked to the driven wheel 342. With the fixed connection between the drive belt 343 and the horizontal bracket 32, the slider 31 is driven to slide along the transverse guide rail 30. The platform 33 carries the metal parts to be cooled and is transported from one end of the production line to the cooling area.

[0019] The working principle of this utility model is as follows: The electrical components in this invention are all triggered by a controller. During operation, the water tank 20 is filled with cooling water, the drive motor 35 starts, driving the drive wheel 341 to rotate. The transmission belt 343, in conjunction with the driven wheel 342, drives the slider 31 to slide along the transverse guide rail 30 through the fixed connection between the transmission belt 343 and the horizontal support 32. The platform 33 carries the metal part to be cooled and smoothly transports it to the cooling area. After the metal part reaches the designated position, the telescopic cylinder 242 is activated, pushing the arc-shaped clamp 241 to retract towards the center. The friction of the inner silicone anti-slip pad is used to clamp the workpiece. The platform 33 moves away from the spray area, and the drainage groove on the arc-shaped clamp 241 drains away the residual coolant on the contact surface, preventing liquid accumulation from affecting the clamping stability and subsequent cooling effect. The coolant in the water tank 20 is pumped by the water pump 21. The water is extracted and transported to the spray assembly 22 through the water supply pipe 23. When the water supply pipe 23 passes through the heat sink 26, the fan 25 blows air through the multi-layer finned heat sink 26 to pre-cool the cooling water in the water supply pipe 23. The upper spray gun 221 and the lower spray gun 222 receive the pre-cooled cooling water. The upper spray gun 221 and the lower spray gun 222 cooperate to form a three-dimensional spray area with atomizing nozzles, which cools the metal part from the top and bottom and accelerates heat exchange. After cooling is completed, the platform 33 returns to the bottom of the workpiece, the telescopic cylinder 242 moves in the opposite direction, the arc clamp 241 is released, and the platform 33 moves to the bottom of the fan 25. At this time, the air force will pass through the heat sink 26 to cool the metal part again. After cooling, the metal part is conveyed out of the device.
