Description

Technical Field

[0001] The present application relates to the technical field of auxiliary equipment for steel pipe welding production, and in particular to a cooling water cooling and reflux equipment for steel pipe processing. Background Art

[0002] The processing and production process of steel pipes includes the step of using a argon arc welding gun to weld the connection parts of the steel pipes. Since the argon arc welding gun uses a tungsten rod as a conductor to directly contact the molten metal, if the operation time is too long, the temperature of the argon arc welding gun will rise sharply, and eventually the handle chuck will be burned. Therefore, a large amount of cooling water is required to cool the welding parts of the weldment and the argon arc welding gun during the welding process. The used cooling water will be recollected and diverted to the cooling water reservoir for recycling.

[0003] In the actual production process, it is found that the temperature of the cooling water will rise rapidly after it comes into contact with the high-temperature parts of the welding and argon arc welding guns. The water temperature of the cooling water reservoir will continue to rise as the welding operation time increases, which will eventually affect the cooling efficiency and also lead to problems such as shortened welding equipment life and reduced welding quality of welded parts. If you want to keep the cooling water temperature in the reservoir at a low level, the conventional response is to expand the reservoir and increase the use of cooling water. This method has poor overall economic and environmental performance and consumes more resources.

[0004] With respect to the above-mentioned related technologies, the inventors found that the cooling water will heat up during use and will affect the cooling efficiency after reflux. Conventional countermeasures have the defects of high resource consumption, poor economy and environmental protection. Summary of the invention

[0008] By adopting the above technical scheme, the support frame plays a role of fixing the position of the water tank and provides a connection position for the installation of the water tank. The water tank plays a role of collecting and refluxing cooling water. The spray mechanism installed on one side of the water tank can atomize the high-temperature cooling water at high pressure and spray it on the heat transfer mechanism in the water tank, thereby increasing the effective contact area between the cooling water and the heat exchange mechanism. The heat sink in the heat exchange mechanism can guide the heat in the cooling water to the outside of the water tank, thereby playing a cooling role.

The pipe body plays a diverting role for the cooling water. The pipe body cooperates with the screen to filter the cooling water to prevent the steel slag contained in the cooling water from entering the spray gun and causing blockage to the spray gun.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0037] The processing and production process of steel pipes includes the step of using a argon arc welding gun to weld the connection parts of the steel pipe. Since the argon arc welding gun uses a tungsten rod as a conductor to directly contact the molten metal, if the continuous operation time is too long, the temperature of the argon arc welding gun will rise sharply, and eventually the handle chuck will be burned. Therefore, a large amount of cooling water is needed to cool the welding parts of the weldment and the argon arc welding gun during the welding process. The used cooling water will be recollected and diverted to the cooling water reservoir for recycling. In the actual production process, it is found that the temperature of the cooling water will rise rapidly after contacting the high-temperature parts of the welding and argon arc welding gun. The water temperature of the cooling water reservoir will continue to rise with the increase of welding operation time, which will eventually affect the cooling efficiency, shorten the life of the welding equipment, and reduce the welding quality of the weldment. If you want to keep the cooling water temperature in the reservoir at a low level, the conventional response is to expand the reservoir and increase the use of cooling water. This method has poor overall economic and environmental protection performance and consumes more resources. In order to maintain the cooling water temperature in the water reservoir at a low level while ensuring environmental protection and economy, and to improve the cooling efficiency of the cooling water, the present application provides a cooling water cooling and reflux equipment for steel pipe processing.

The cooled cooling water can flow back from the bottom of the water storage tank 2 to the cooling water pool, thereby achieving the purpose of the invention of maintaining the cooling water temperature at a low level.

Among them, the support leg 11 is vertically fixed on the ground, and the support plate 13 is connected to the end of the support leg 11 close to the ground by welding. The support plate 13 can be a circular pad with an area larger than the cross-sectional area of ​​the support leg 11. A plurality of bolt holes for installing anchor bolts are provided on the support plate 13. A plurality of bolt holes are evenly distributed circumferentially on the support plate 13.

The ladder 14 is fixedly installed on the support leg 11 and one side of the water tank 2 perpendicular to the ground. A guard ring is welded at the end of the ladder 14 away from the ground to prevent climbers from accidentally falling.

[0040] Reference Figure 1 and Figure 2 The water storage tank 2 includes a box body 21, a deflector 22, a drain pipe 23, a drain valve 24, a turbine blade 25 and an axial flow fan 26. Among them, the box body 21 can be a hollow rectangular metal box with openings at both ends. A grid plate 211 is welded on the top of the box body 21. A guardrail 212 is welded on the top of the box body 21 along the circumferential direction to prevent climbers from accidentally falling. A deflector 22 is welded on the bottom of the box body 21. The deflector 22 can be a metal cover in the shape of a quadrangular pyramid. The end of the deflector 22 with a larger cross-sectional area is welded to the bottom edge of the box body 21 and is internally connected. The drain pipe 23 is connected to the end of the deflector 22 with a smaller cross-sectional area. A drain valve 24 is installed between the drain pipe 23 and the deflector 22. The drain valve 24 can be used to control the opening and pipe wall of water discharge. When the drain valve 24 is closed, cooling water accumulates inside the deflector 22 and the box body 21. The turbine blade 25 is installed at one end of the drain pipe 23 away from the air guide cover 22. The rotating shaft 41 of the turbine blade 25 is inserted into the turning position of the drain pipe 23 and is rotatably connected to the drain pipe 23.

The bevel gears at both ends of the transmission rod are respectively meshed with the bevel gears on the rotating shaft 41 of the axial flow fan 26 and the bevel gears on the rotating shaft 41 of the turbine blade 25 to realize transmission connection. After the drain valve 24 is closed for a period of time and a certain amount of cooling water is accumulated in the box body 21, the drain valve 24 is opened, and the turbine blade 25 will rotate under the impact of a large amount of cooling water, and the transmission rod will transmit the torque generated by the rotation of the turbine blade 25 to the axial flow fan 26. The rotation of the axial flow fan 26 generates airflow to accelerate the heat dissipation efficiency of the heat exchange mechanism 4 .

[0041] Reference Figure 1 and Figure 3The spray mechanism 3 includes a water inlet pipe 31, a spray gun 32 and a connecting pipeline 33. Among them, the water inlet pipe 31 includes two mounting frames 311 vertically mounted on the side wall of the water storage tank 2. The mounting frame 311 can be composed of two angle steels welded and fixed at an angle to each other. The pipe body 312 can be a hollow metal pipe connected at both ends. The screen 313 is slidably connected and arranged along the axis direction of the pipe body 312. One end of the pipe body 312 is connected to the connecting pipeline 33, and the other end of the pipe body 312 is installed with a drain valve 314. The end of the pipe body 312 equipped with the drain valve 314 is connected to the cooling water hot water pool. After the drain valve 314 is opened, the screen 313 in the pipe body 312 can slide and be removed, and the impurities such as steel slag filtered out in the pipe body 312 can be taken out to the outside of the pipe body 312. The spray gun 32 is set in multiple groups, and the number of the spray guns 32 in the embodiment of the present application is twelve groups. The spray direction of the spray gun 32 is parallel to the ground. The spray gun 32 is vertically penetrated on the side wall of the water storage tank 2. Multiple spray guns 32 are evenly distributed along the length direction of the side wall of the water storage tank 2. The connecting pipeline 33 includes multiple rubber hoses and mounting channel steels for fixing the rubber hoses. The mounting channel steels are welded to the side wall of the water storage tank 2 and play an auxiliary fixing role for the rubber hoses. The rubber hoses are coiled with each other, one end of the rubber hose is connected to the tube body 312, and the other end is respectively connected to multiple spray guns 32. The connecting pipeline 33 can evenly guide the filtered cooling water in the tube body 312 to the spray gun 32. The spray gun 32 can atomize and cool the cooling water.

[0042] Reference Figure 1 and Figure 4 The heat exchange mechanism 4 includes a rotating shaft 41, a heat sink 42, a water baffle 43 and a limiting end block 44. The rotating shaft 41 can be a hollow metal shaft. The two ends of the rotating shaft 41 are respectively connected to the compressed air source. The rotating shaft 41 is rotatably connected to the water storage tank 2. A mounting rod is fixedly welded on the rotating shaft 41 perpendicular to the axis. The heat sink 42 is fixedly sleeved on the mounting rod and distributed in groups. Each group of heat sinks 42 is equidistant from each other and corresponds one by one to the spray gun 32 in the spray mechanism 3. Each group of heat sinks 42 is vertically mounted with a water baffle 43. The water baffle 43 is arranged perpendicular to the plane where the heat sink 42 is located and is slidably connected to the heat sink 42 along the length direction of the heat sink 42. The limiting end blocks 44 are welded at both ends of the heat sink 42. The limiting end blocks 44 fix each group of heat sinks 42 and limit the relative sliding between the water baffle 43 and the heat sink 42.

[0043] The implementation principle of a cooling water cooling and reflux device for steel pipe processing in the embodiment of the present application is as follows: the temperature of the cooling water for welding increases after use, and the heated cooling water converges into the cooling water hot water pool for temporary storage. The pumping equipment pumps the cooling water with a higher temperature in the cooling water hot water pool into the water inlet pipe 31, and after being filtered by the screen 313, it is evenly divided into the spray gun 32 through the connecting pipe 33, and is atomized and sprayed on the heat sink 42 under the pressurized action of the spray gun 32. The heat sink 42 conducts the heat of the atomized cooling water to the top of the water storage tank 2 and outside the water storage tank 2. After the atomized cooling water contacts the heat sink 42 and the water baffle 43, it is reliquefied and flows into the water storage tank 2, and is collected to the drain pipe 23 through the guide cover 22. After a period of time, the heat sink 42 rotates driven by the rotating shaft 41. The cold end and the hot end of the heat sink 42 are interchanged, thereby improving the efficiency of heat exchange and cooling. During the rotation process, the water retaining plate 43 slides along the heat sink 42, and finally remains at one end of the heat sink 42 close to the water tank 2, continuing to realize the water retaining function while avoiding affecting the heat dissipation efficiency of the cold end of the heat sink 42. When a certain amount of cooling water is accumulated in the water tank 2, the drain valve 24 is opened, and the turbine blades 25 rotate under the flushing of the cooling water, and drive the axial flow fan 26 to rotate. The airflow generated by the rotation of the axial flow fan 26 can accelerate the heat dissipation efficiency of the cold end of the heat sink 42. After using for a period of time, the drain valve 314 of the water inlet pipe 31 is opened, and the screen 313 is pulled out from the tube body 312, and the impurities such as steel slag screened out in the tube body 312 are taken out together. The screen 313 can be cleaned and reinstalled for continued use.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
