Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-frequency welded pipes, in particular to a cooling device for producing high-frequency welded pipes. Background Art
[0002] High-frequency welding machines use a high-frequency current passing through an induction coil to generate an alternating magnetic field. When stainless steel or iron pipes are placed in this magnetic field, electromagnetic induction generates eddy currents within the pipe. These eddy currents flow through the pipe, rapidly heating it. Once the required welding temperature is reached, appropriate pressure is applied to tightly bond the contact surfaces of the pipes, achieving the weld.
[0003] Chinese patent publication number CN217529586U discloses a welding cooling device for a high-frequency pipe welding machine. This device belongs to the field of welding pipe cooling technology and comprises a housing, a placement frame inserted into an opening on the housing surface, and a cold water tank connected to the rear wall of the housing. The placement frame has several water guide holes formed in its inner bottom wall. A spray box is connected to the interior top wall of the housing via two support rods, and the bottom end of the spray box is connected to multiple evenly distributed nozzles. A collection dish is placed on the interior bottom wall of the housing, and a filter is removably connected to the inner side wall of the collection dish. The top and bottom of the cold water tank are respectively connected to a water outlet pump and a water return pump. A heat dissipation frame is embedded in a through-hole formed in one side of the housing outer wall. An exhaust fan and a dust screen are removably mounted on the inner side wall of the heat dissipation frame from the inside to the outside. This welding cooling device for a high-frequency pipe welding machine has a simple structure and is highly practical.
[0004] However, in the above technical solution, the cooling water is collected only through the filter, and is pumped out by the return pump and collected again in the cold water tank. However, when the filter is in use, a smaller mesh is required to separate the metal debris and non-metal debris. If the mesh of the filter is clogged during use, the speed of the cooling liquid return will be reduced, making it difficult to circulate the cooling liquid subsequently. Utility Model Content

[0030] Example 3
[0031] like Figure 1-Figure 2 As shown, the present invention proposes a cooling device for high-frequency welded pipe production. Compared with the second embodiment, this embodiment records the detailed structure of the anti-blocking component. The anti-blocking component includes a moving cylinder 17, a telescopic device 18, a deceleration plate 19, a magnetic member 20 and an auxiliary component. The moving cylinder 17 and the water outlet pipe 13 have the same center, and the water outlet pipe 13 is sleeved on the outside of the moving cylinder 17.
[0032] In an optional embodiment, the movable cylinder 17 is composed of a supporting cylinder 21 and a movable cylinder 22. The supporting cylinder 21 is sleeved on the outside of the movable cylinder 22. One end of the supporting cylinder 21 is connected to the connecting block. A supporting ring is connected to the inner wall of the supporting cylinder 21. The movable cylinder 22 is composed of two arc-shaped plates. The deceleration plate 19 and the magnetic attraction member 20 are connected to the inner wall of the arc-shaped plates.
[0033] The telescopic device 18 is connected to the water outlet pipe 13, and the telescopic end of the telescopic device 18 is connected to a connecting plate, which is connected to the moving cylinder 17; the telescopic device 18 can be selected from but not limited to a hydraulic cylinder; there are multiple speed reducers 19, which are connected to the moving cylinder 17; the speed reducers 19 are arranged in an interlaced manner, and the speed reducers 19 are provided with bumps to reduce the liquid flow rate; the magnetic member 20 is connected to the moving cylinder 17; the magnetic member 20 is selected from a high-temperature resistant aluminum nickel cobalt magnet or a neodymium iron boron magnet; the auxiliary component is connected to the moving cylinder 17, and when the auxiliary component is in use, the moving end of the auxiliary component moves vertically to increase the gap between it and the magnetic member 20;

[0035] In summary, when the present invention is used, the welded pipe passes through the cooling box 1 from the feed port 2 and is moved out from the discharge port 3. The support member in the cooling box 1 supports the pipe. At the same time, the water outlet pump 6 starts to extract the cooling liquid in the cold water tank 5, and transports it to the cooling pipe 7 and sprays it on the high-temperature pipe from the nozzle 8, thereby reducing the temperature of the pipe. The water vapor generated by the high contact of the cooling liquid rises and is guided by the gas collection hood 10 into the outlet pipe 4. The baffle 9 on the outlet pipe 4 blocks the steam and accelerates its condensation. The condensed water droplets are guided by the drainage hood 12 together with the cooling liquid sprayed from the nozzle 8 to slide toward the water outlet pipe 13. The cooling liquid drips on the deceleration plate 19. The dripping speed is reduced by the inclination of the deceleration plate 19 and the bumps on its surface. After deceleration, the cooling liquid drips on the magnetic suction part 20, and the cooling The metal impurities contained in the cooling liquid are attracted and collected by the magnetic element 20. The flow rate of the cooling liquid is low to prevent the impurities from being washed away, while the non-metallic impurities or impurities that cannot be adsorbed by the magnetic element 20 will fall on the auxiliary filter 25. The mesh of the auxiliary filter 24 is larger than the mesh of the filter 14, and the larger particles that can block the filter 14 are collected, and the smaller particles fall directly. After a certain amount of particles are collected, their weight will pull down the elastic element 24. After the length of the elastic element 24 is extended, the distance between the auxiliary filter 24 and the magnetic element 20 increases, preventing the accumulation of particles and their volume from clogging the outlet pipe 13 and affecting its normal drainage. The cooling liquid that has been screened twice then flows into the filter 14 and is filtered into the reflux box 11. It is extracted by the reflux pump 15 and enters the cold water tank 5 again. The heat is dissipated by the water circulation radiator on the cold water tank 5 for recycling.
[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
