Description

Technical Field

[0001] The utility model relates to the technical field of cooling water, in particular to a cooling water cooling device for a medium frequency furnace. Background Art

[0002] The molybdenum plug is made of molybdenum-titanium-cobalt-carbon alloy and is used to produce the plug of the mandrel of the seamless steel pipe piercing machine. It is used to punch seamless steel pipes. When producing the molybdenum plug, molybdenum powder is used as the raw material to add rare earth materials, and then it is processed through mixing, molding, shape processing, and finally high-temperature sintering. After the shape processing, the plug blank should be placed in the medium frequency furnace for high-temperature sintering. When the furnace is in use, due to the large current, the induction coil part of the furnace body generates a lot of heat, and a corresponding cooling system must be equipped. At present, the cooling method of the medium frequency furnace is to set a water jacket on the outside of the coil, and the water jacket is connected to the external cooling tower. By driving the cooling water to circulate between the water jacket and the cooling tower, the induction coil part can be cooled down;

[0003] However, when the existing cooling tower cools down the cooling water, the cooling water is pumped to the water distributor at the top of the tower by a water pump, and then the liquid is evenly sprayed in the entire tower in a mist form through a nozzle to make the cooling water and air fully contact to achieve the purpose of cooling. However, in the process of cooling water descending, a water curtain is formed from top to bottom, which makes it difficult for the hot and humid air to move upward, which not only affects the cooling efficiency, but also causes turbulence between the hot and humid air and the cold air, causing the cooling water to splash out from both sides of the cooling tower; therefore, we propose a cooling water cooling device for a medium frequency furnace. Utility Model Content

[0004] The utility model aims to provide a cooling water cooling device for a medium frequency furnace, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling water cooling device for a medium frequency furnace, comprising a cooling tower, a water inlet pipe is fixed through the top of the cooling tower, the tail end of the water inlet pipe is connected to a hollow turntable through a rotating joint, a first gear is fixedly mounted on the outer wall of the rotating part of the rotating joint, a second gear is meshed on the outer wall of the first gear, the second gear is fixed to the outer end of the transmission shaft of the servo motor, the servo motor and the inner wall of the cooling tower are fixedly connected, and an arc-shaped water distributor is fixedly connected to one side of the bottom of the hollow turntable.

[0006] By adopting the above technical scheme, firstly, the water to be cooled is introduced into the inner cavity of the hollow turntable by using the water inlet pipe, and then enters the water distributor, and is sprayed by the water distributor to form a water curtain. At the same time, starting the servo motor can drive the second gear to rotate, and the grassroots people make the first gear rotate, so as to drive the hollow turntable to rotate, and then the water distributor can be rotated accordingly, driving the water distributor to rotate and distribute water evenly. In the process of water distribution, the formation of a closed water curtain can be avoided, and it is ensured that there is always space on both sides of the water curtain, so as to effectively ensure that the hot and humid air moves upward, thereby avoiding the accumulation of hot and humid air, thereby avoiding the turbulence of hot and humid air and cold air, and ensuring the cooling effect.

[0007] As a preferred embodiment of the utility model, the upper side of the outer wall of the cooling tower is fixedly connected with a surrounding pipe, the outer end of the surrounding pipe is fixedly connected with an exhaust fan, and the outer end of the exhaust fan is fixedly connected with an air outlet pipe.

[0008] By adopting the above technical solution, when the hot and humid air rises, the exhaust fan is used to generate negative pressure in the surrounding pipe, thereby improving the rising effect of the hot and humid air. At the same time, the hot and humid air will pass through the surrounding pipe, so that the water in the hot and humid air will adhere to the inner wall of the surrounding pipe under the action of its own gravity after condensation, and then it will automatically flow back into the cooling tower after gathering into a large amount, thereby realizing recycling.

[0009] As a preferred embodiment of the present invention, the bottom of the cooling tower is fixedly connected with a drain pipe.

[0010] By adopting the above technical solution and setting the drain pipe, the cooled liquid can be discharged for reuse.

[0011] As a preferred embodiment of the utility model, a cold air pipe is fixedly connected to one side of the outer wall of the cooling tower.

[0012] By adopting the above technical solution and setting the cold air pipe, cold air can be introduced into the cooling tower, thereby ensuring the cooling effect on the water.

[0013] As a preferred embodiment of the present utility model, a glass observation window is embedded in the middle of the outer wall of the cooling tower.

[0014] By adopting the above technical solution and providing a glass observation window, it is convenient to observe the internal conditions of the cooling tower.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The technical solution of the present application is a cooling water cooling device for a medium frequency furnace, which introduces water to be cooled into a hollow turntable through a water inlet pipe, and then distributes water in a cooling tower using an arc-shaped water distributor, and then drives the second gear to drive the first gear to rotate through a servo motor, so that the hollow turntable rotates, so that the water distributor can evenly spray and distribute water in the cooling tower, and at the same time can avoid the formation of a closed water curtain, ensuring that there is always space on both sides of the water curtain, so that the hot and humid air can effectively move upward, thereby avoiding the accumulation of hot and humid air, thereby avoiding the generation of turbulence between hot and humid air and cold air, and ensuring the cooling effect;

[0017] The humid hot air is extracted by the exhaust fan, which further improves the rising effect of the humid hot air. The humid hot air will pass through the surrounding pipe, so that the water in the humid hot air will adhere to the inner wall of the surrounding pipe under the action of its own gravity after condensation, and then it will automatically flow back into the cooling tower after gathering into a large amount, so as to achieve recycling.

[0026] See also Figure 1-3The utility model provides a technical solution: a cooling water cooling device for a medium frequency furnace, comprising a cooling tower 1, a water inlet pipe 11 is fixed through the top of the cooling tower 1, the tail end of the water inlet pipe 11 is connected to a hollow turntable 3 through a rotary joint 31, a first gear 32 is fixedly sleeved on the outer wall of the rotating part of the rotary joint 31, a second gear 33 is meshed on the outer wall of the first gear 32, the second gear 33 is fixed to the outer end of the transmission shaft of the servo motor 34, the servo motor 34 is fixedly connected to the inner wall of the cooling tower 1, and an arc-shaped water distributor 35 is fixedly connected to one side of the bottom of the hollow turntable 3;

[0027] In actual use, firstly, the water to be cooled is introduced into the inner cavity of the hollow turntable 3 by using the water inlet pipe 11, so that the water enters the water distributor 35, and the water distributor 35 is used to spray the water to form a water curtain. At the same time, the servo motor 34 is started to drive the second gear 33 to rotate, and the first gear 32 is rotated, so that the hollow turntable 3 can be driven to rotate, and then the water distributor 35 can be rotated accordingly, driving the water distributor 35 to rotate and distribute water evenly. In the process of distributing water, the formation of a closed water curtain can be avoided, and space is ensured to exist on both sides of the water curtain at all times, so that the humid and hot air can be effectively moved upward, thereby avoiding the accumulation of humid and hot air, thereby avoiding the turbulence of humid and hot air and cold air, and ensuring the cooling effect;

[0028] Furthermore, a drain pipe 12 is fixedly connected to the bottom of the cooling tower 1. The arrangement of the drain pipe 12 enables the cooled liquid to be discharged for reuse.

[0029] Furthermore, a glass observation window 14 is embedded in the middle of the outer wall of the cooling tower 1. The arrangement of the glass observation window 14 makes it convenient to observe the internal conditions of the cooling tower 1.

[0030] It is worth mentioning that a cold air pipe 13 is fixedly connected to one side of the outer wall of the cooling tower 1. The cold air pipe 13 is arranged so that cold air can be introduced into the cooling tower 1, thereby ensuring the cooling effect on the water.

[0031] like Figure 1 and 2 As shown; a surrounding pipe 2 is fixedly connected to the upper side of the outer wall of the cooling tower 1, an exhaust fan 21 is fixedly connected to the outer end of the surrounding pipe 2, and an air outlet pipe 22 is fixedly connected to the outer end of the exhaust fan 21. When the humid hot air rises, the exhaust fan 21 is utilized to generate negative pressure in the surrounding pipe 2, thereby enhancing the rising effect of the humid hot air. At the same time, the humid hot air will pass through the surrounding pipe 2, so that the water in the humid hot air will adhere to the inner wall of the surrounding pipe 2 under the action of its own gravity after condensation, and then it will automatically flow back into the interior of the cooling tower 1 after gathering into a large amount, thereby realizing recycling.

There is always space on the side, which can effectively ensure that the hot and humid air moves upward, thereby avoiding the accumulation of hot and humid air, thereby avoiding turbulence of hot and humid air and cold air, and ensuring the cooling effect. When the hot and humid air rises, the exhaust fan 21 is used to generate negative pressure around the pipe 2, thereby enhancing the rising effect of the hot and humid air. At the same time, the hot and humid air will pass through the surrounding pipe 2, so that the water in the hot and humid air will adhere to the inner wall of the surrounding pipe 2 under the action of its own gravity after condensation, and then it will automatically flow back into the interior of the cooling tower 1 after gathering into a large amount, thereby realizing recycling.
