Description

Technical Field

[0001] The utility model relates to the technical field of composite steel pipe water cooling, in particular to a composite steel pipe direct-spray-free water cooling device. Background Art

[0002] During the production process of composite steel pipes, after the anti-corrosion layer is wrapped around the steel pipe, the temperature of the coating is often higher than the ambient temperature. If proper cooling is not performed, the coating surface will cool unevenly, too quickly or too slowly, leading to quality problems such as coating defects and blistering. Moreover, the bonding of the coating to the steel pipe surface also needs to be completed under certain temperature and humidity conditions, otherwise there will be insufficient bonding. Water cooling can quickly reduce the temperature of the steel pipe surface to an appropriate range, thereby avoiding coating defects and bonding problems.

[0003] Most of the existing cooling methods are to directly spray cold water onto the surface of the composite steel pipe through a cold water pipe, which can easily form water droplets on the surface of the composite steel pipe that has not yet been finalized, and can also easily cause cracks due to uneven cooling, affecting the appearance and corrosion resistance of the composite steel pipe; and when the composite steel pipe comes into contact with cold water, it is easy to generate a large amount of high-temperature smoke, which is directly discharged into the surrounding environment, easily causing pollution to the surrounding environment, and needs to be improved.

[0030] Reference Figures 1 to 4 , which is an embodiment of the utility model, provides a composite steel pipe water cooling device without direct spraying, including a steel pipe spraying mechanism 100, a water flow buffer component 200 and a self-cooling smoke exhaust component 300;

[0031] The steel pipe spray mechanism 100 includes a spray pipe 101, a water pump 102 and a water supply pipe 103, and the water inlet and outlet of the water pump 102 are respectively connected to the water supply pipe 103 and the spray pipe 101;

[0032] The water flow buffer assembly 200 includes a water flow buffer cover 201, a buffer guide plate 202, a flow interception baffle 203 and a flow equalizer 204 for cooling water diversion. The top of the water flow buffer cover 201 is connected to the water outlet of the spray pipe 101, and the bottom of the water flow buffer cover 201 is connected to the buffer guide plate 202, so that the cooling water flows from the water flow buffer cover 201 to the side wall of the buffer guide plate 202; the flow interception baffle 203 is arranged on the side wall of the buffer guide plate 202, and the buffer guide plate 202 is connected to the water outlet of the spray pipe 101. The bottom end is connected to the flow equalizer plate 204, and the flow equalizer plate 204 is provided with a flow equalizer hole 2041 for cooling water to flow out of the spray composite steel pipe; the cross-section of the buffer guide plate 202 is a conical structure, and the flow equalizer plates 204 are arranged on both sides of the bottom end of the buffer guide plate 202; the flow equalizer plates 204 are provided with two groups, and a group of composite steel pipes to be cooled are arranged at the bottom end of the two groups of flow equalizer plates 204; a cooling water pool 400 is arranged below the flow equalizer plate 204, and a water outlet pipe 401 is connected to one side of the cooling water pool 400.

[0033] The self-cooling smoke exhaust component 300 includes a smoke hood 301, a smoke pipe 302 and a smoke fan 303 arranged at the bottom of the buffer guide plate 202, the end of the smoke hood 301 is connected to the smoke pipe 302, and the smoke pipe 302 is connected to the smoke fan 303; the conical cavity at the bottom of the buffer guide plate 202 is set as the smoke hood 301, and the bottom of the smoke hood 301 is arranged with a smoke inlet 3011; the intercepting baffles 203 are staggered on the buffer guide plate 202; the self-cooling smoke exhaust component 300 also includes a smoke filter box 304, the air outlet of the smoke fan 303 is connected to the bottom end of the smoke filter box 304 through a pipeline, the interior of the smoke filter box 304 is arranged with activated carbon adsorption filler 305, and the top of the smoke filter box 304 is connected with a smoke exhaust pipe 306.

[0034] In this embodiment: when in use, the power of the water pump 102 and the smoke exhaust fan 303 is turned on; the water pump 102 is started, so that the water pump 102 draws out the external cooling water source through the water supply pipe 103, and then injects the cooling water source into the water flow buffer cover 201 through the spray pipe 101. After the cold air water enters the water flow buffer cover 201, it is dispersed by the buffer guide plate 202 with a conical structure, so that the water flow is dispersed to both sides of the buffer guide plate 202 and flows obliquely along its outer wall. In this process, the interception baffle 203 plays an intermittent interception role on the water flow, thereby reducing the impact force of the water flow.

[0035] After the water flows onto the flow equalizer plate 204 , it passes through the flow equalizer holes 2041 and falls onto the high-temperature composite steel pipe arranged below it, cooling it; the cooling water passes through the composite steel pipe and falls into the cooling water pool 400 and can be discharged through the outlet pipe 401 .

[0036] While the composite steel pipe is cooling, the smoke exhaust fan 303 draws the high-temperature smoke generated by the composite steel pipe meeting cold water into the smoke exhaust hood 301, and performs heat exchange on the high-temperature smoke through contact with the lower surface of the buffer guide plate 202. The smoke is then sucked to the smoke filter box 304 through the smoke exhaust pipe 302, and the smoke is purified, filtered and adsorbed by the activated carbon adsorption filler 305. Finally, the clean gas is discharged through the smoke exhaust pipe 306.

[0037] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
