Description

Technical Field

[0001] The present application relates to the technical field of annealing furnace cooling devices, and in particular to a multifunctional cooling device. Background Art

[0002] Annealing furnace is a common heat treatment process equipment, mainly used for annealing of products.

[0003] During the cooling process of an annealing furnace, cold air is injected into the furnace to replace the hot air, thereby achieving a rapid cooling effect. Typically, this is accomplished using a fan and a gas pipeline. One end of the pipeline is connected to the fan's outlet, and the other end is inserted into the furnace. The fan injects cold air into the furnace.

[0004] However, in actual production, the products in the annealing furnace are diverse and have different characteristics. When annealing different products, the types of gases injected into the furnace also vary. In the related art, the flexibility of changing the type of gas injected into the furnace is poor, making it inconvenient for workers to quickly change the type of gas injected into the furnace. Utility Model Content

[0008] By adopting the above technical solution, during the actual production process, the air intake branch pipes on the air intake duct are connected to different types of gas sources respectively. By opening and closing the branch control valve body, the air intake duct and different gas sources can be connected, thereby realizing the rapid conversion of the air type injected into the furnace body, thereby improving the flexibility in the process of changing the gas type.

[0009] Optionally, a support base is provided below the fan, and the support base includes a mounting frame for supporting the fan and a plurality of foot cups for supporting the mounting frame, and the plurality of foot cups are evenly distributed below the mounting frame.

[0010] By adopting the above technical solution, a mounting frame is provided to support and fix the fan, thereby improving the stability of the fan during use. The mounting frame is spaced apart from the ground by the foot cup, thereby reducing the possibility of rust on the mounting frame.

[0012] By adopting the above technical solution, an opening is set at one end of the air inlet duct away from the fan. During actual production, it can be connected to the inside of the furnace body, and the control valve body is controlled to be closed. At this time, the fan can extract the gas inside the furnace body, and then inject it into the furnace body again after cooling treatment, thereby realizing the recycling of the gas in the furnace.

[0013] Optionally, a smoke exhaust pipe is provided on the air inlet duct at a position corresponding to the end control valve body and the air inlet branch pipe, and a smoke pipe control valve body is provided on the smoke exhaust pipe.

[0016] By adopting the above technical solution, during the flue gas emission process, the anti-intrusion pipe is controlled to be closed, preventing the flue gas from spreading toward the fan or the air intake pipe, thereby reducing the occurrence of erosion of the fan.

[0017] Optionally, a support base is provided below the fan, the support base includes a base body and a universal wheel, the universal wheel is installed at the bottom of the base body, and the fan is installed above the base body.

The adjusting screw is threadedly connected to the base body, and the support member is installed at the end of the adjusting screw close to the ground. Rotating the adjusting screw can drive the support member to move in the vertical direction.

[0020] By adopting the above technical solution, during transportation of the cooling device, the support member is moved upward by adjusting the screw to maintain a clearance from the ground. After the cooling device is moved to the designated position, the support member is driven downward by adjusting the screw to replace the universal wheel to support the base, thereby extending the life of the universal wheel.

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] The embodiment of the present application discloses a multifunctional cooling device.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 A multifunctional cooling device includes: a fan 8, an air inlet duct 1 and an air outlet duct 2, one end of the air outlet duct 2 is connected to the air outlet of the fan 8, and the other end is connected to the inside of the furnace body (here referring to the annealing furnace). The air inlet duct 1 is provided with at least two air inlet branch pipes 11, and in this embodiment, two air inlet branch pipes 11 are provided. The air inlet branch pipe 11 is connected to the air inlet duct 1. The two air inlet branch pipes 11 are respectively connected to two different types of gas sources. The air inlet branch pipe 11 is provided with a branch control valve body 12 (a solenoid valve in this embodiment) for controlling the on and off of the air inlet branch pipe 11. In the actual production process, by controlling the opening and closing of the branch control valve bodies 12 on different air inlet branch pipes 11, the fan 8 is connected to different gas sources, which is convenient for the staff to inject different types of air into the furnace body and improves the flexibility when changing the type of injected gas.

[0030] Reference Figure 1 and Figure 2A support base 3 is provided below the fan 8, supporting the fan 8 and improving its stability during use. The support base 3 includes a mounting frame 31, which comprises a plurality of channel steels 32 welded together in a crisscross pattern to form a mesh structure. The fan 8 is fixed to the mounting frame 31 via screws. The support base 3 also includes a plurality of foot cups evenly distributed below the mounting frame 31. The foot cups are supported on the ground to space the support base 3 from the ground and reduce the risk of rust.

[0031] Reference Figure 1 and Figure 2 An end control valve 4, used to control the flow of air from the air inlet duct 1, is located at the end of the air inlet duct 1 facing away from the fan 8. In special production situations where furnace gas recycling is required, the end of the air inlet duct 1 facing away from the fan 8 is connected to the interior of the furnace. During furnace cooling, the end control valve 4 is opened and the branch control valve 12 is closed, allowing the fan 8 to extract gas from the furnace. The gas is then cooled in a heat exchanger and then reinjected into the furnace, achieving furnace gas recycling.

[0032] Reference Figure 1 and Figure 2 The air inlet duct 1 is also provided with a smoke exhaust duct 5. The smoke exhaust duct 5 is located between the end valve body and the air inlet branch pipe 11, and is provided with a smoke duct control valve body for controlling the on / off of the smoke exhaust duct. An anti-intrusion valve body 6 for controlling the on / off of the air inlet duct 1 is provided between the smoke exhaust duct and the air inlet branch pipe 11. The anti-intrusion valve body 6 controls the on / off of the air inlet duct 1, and the connection and disconnection between the smoke exhaust duct 5, the air inlet branch pipe 11, and the fan 8. When the furnace body does not need to be cooled, the anti-intrusion valve body 6 can be controlled to open, and at the same time, the valve body on the smoke exhaust duct 5 can be controlled to open, so that the smoke generated in the furnace can be discharged from the smoke exhaust port, while preventing the smoke from spreading to the fan 8 or the air inlet branch pipe 11.

[0033] The implementation principle of a multifunctional cooling device in an embodiment of the present application is: a smoke exhaust pipe 5 is provided to facilitate the exhaust of smoke generated during the normal heating process of the product by the furnace body.

[0034] Example 2

[0035] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that the structure of the support base 3 is different. In this embodiment, the support base 3 includes a base body 33 and a universal wheel 34 installed at the bottom of the base body 33. The fan 8 is fixed to the base body 33 by screws. The universal wheel 34 can drive the base body 33 to move when rolling, thereby driving the fan 8 to move, making it convenient for the staff to adjust the position of the cooling device.

[0036] Reference Figure 3 and Figure 4 The seat body 33 is a plate-like structure as a whole, and the seat body 33 is arranged horizontally. A support assembly 7 is provided on the side of the seat body 33 close to the ground. The support assembly 7 includes a support member 71 and an adjusting screw 72. The adjusting screw 72 is arranged vertically and is threadedly connected to the seat body 33. The support member 71 is rotatably connected to the end of the adjusting screw 72 close to the ground, and the rotation axis of the support member 71 is coaxial with the adjusting screw 72. Rotating the adjusting screw 72 can drive the support member 71 to move in the vertical direction. After the support seat 3 moves to the specified position, the support member 71 can be supported on the ground by rotating the adjusting screw 72 to replace the universal wheel 34 to support the support seat 3, thereby increasing the service life of the universal wheel 34. The support member 71 is a truncated cone structure as a whole, and the support member 71 and the adjusting screw 72 are coaxially arranged.

[0037] Reference Figure 3 and Figure 4 The end of the adjusting screw 72 facing away from the ground extends through the base to the side of the base 33 facing away from the ground. A torsion post 73 is provided on the end of the adjusting screw 72 facing away from the ground. The torsion post 73 is in the form of a hexagonal prism. One end of the torsion post 73 is welded to the adjusting screw 72. A staff member can use a wrench to rotate the hexagonal prism, making it easier for the staff to rotate the adjusting screw 72.

[0038] Reference Figure 3 and Figure 4 The support assembly 7 also includes a cylindrical rod-shaped limiter 74. A sliding hole 75 is coaxially defined on the adjustment screw 72. The sliding hole 75 extends through both the adjustment screw and the torque column 73. The limiter 74 slides vertically through the sliding hole 75 and is capable of rotating about its own axis. The limiter 74 has threads on the end closest to the ground. When installing the cooling device, a threaded hole can be pre-drilled in the ground. After the support member 71 abuts the ground, the sliding rod is threaded into the threaded hole, thereby limiting the horizontal displacement of the support member 71 and further improving the stability of the cooling device after installation.

[0039] The implementation principle of a multifunctional cooling device in an embodiment of the present application is as follows: universal wheels 34 are provided under the seat 33 to facilitate staff to move the position of the cooling device.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
