Description

Technical Field

[0001] This utility model relates to the field of refining furnace stirring technology, specifically a bidirectional stirring device for an aluminum alloy refining furnace. Background Technology

[0002] Aluminum alloys are one of the most widely used non-ferrous metal structural materials in industry. They are widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts is increasing. Aluminum alloy refining furnaces are special equipment used to refine aluminum alloy melts. When melting and processing raw materials, aluminum alloy refining furnaces need to stir the raw materials.

[0003] Traditional refining furnaces often employ a unidirectional mechanical stirring or a static furnace body combined with a rotating stirring rod. Unidirectional stirring easily creates a laminar flow zone, resulting in uneven distribution of melt composition. Furthermore, unidirectional stirring can easily lead to mixing dead zones. Therefore, we urgently need a bidirectional stirring device for aluminum alloy refining furnaces. Utility Model Content

[0004] The purpose of this invention is to provide a bidirectional stirring device for an aluminum alloy refining furnace to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a bidirectional stirring device for an aluminum alloy refining furnace, comprising a base, a stirring mechanism being provided at the top of the base, and an exhaust mechanism being provided at the bottom of the base; The stirring mechanism includes a furnace body, a furnace cover rotatably connected to the top of the furnace body, a motor fixedly connected to the top of the furnace cover, a rotating shaft fixedly connected to the output end of the motor, a stirring rod and a first synchronous pulley fixedly connected to the outside of the rotating shaft, a transmission belt internally connected to the first synchronous pulley, a second synchronous pulley internally connected to the transmission belt, a connecting rod fixedly connected to the bottom of the second synchronous pulley, a first gear fixedly connected to the outside of the connecting rod, and a second gear meshing with the outside of the first gear.

[0006] Preferably, the furnace body is rotatably connected to the top of the base, and a support frame is fixedly connected to the top of the base, with one end of the support frame fixedly connected to one end of the furnace cover.

[0007] Preferably, one end of the rotating shaft passes through the furnace cover and extends into the interior of the furnace body, and a support base is provided at the bottom of the second synchronous wheel.

[0008] Preferably, the second gear is fixedly connected to the outside of the furnace body, and multiple stirring rods are provided.

[0009] Preferably, the exhaust mechanism includes a fan, one end of which is connected to a water tank, and one end of the water tank is fixedly connected to an exhaust pipe.

[0010] Preferably, the blower is installed on the top of the furnace cover, and an exhaust pipe is installed at one end of the blower.

[0011] Preferably, one end of the exhaust pipe is screwed to a plurality of activated carbon plates, and the plurality of activated carbon plates are arranged in a linear array.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: Firstly, this utility model introduces raw materials into the furnace body through a feed pipe at the top of the furnace cover. A motor then drives a rotating shaft, which in turn drives a stirring rod to agitate the raw materials inside the furnace. Simultaneously, the rotating shaft's rotation drives a first synchronous pulley on its exterior, which in turn drives an external transmission belt. This causes a second synchronous pulley at the other end of the transmission belt to rotate. The rotation of the second synchronous pulley drives a connecting rod at its bottom, which in turn drives a first gear. This, in turn, causes a second gear meshing with the first gear to rotate. Because the bottom of the furnace body is rotatably connected to the top of the base, and one end of the furnace cover is fixedly connected to the support frame, the furnace body can rotate. Through the bidirectional rotation of the furnace body and the stirring rod, the melt generates a high-intensity shear flow due to the bidirectional speed difference, accelerating the diffusion of alloying elements. This bidirectional movement covers the entire furnace body, avoiding the localized unmelted areas of traditional unidirectional stirring. Only one motor is needed, reducing energy consumption and cost, thus improving stirring efficiency.

[0013] Secondly, this utility model uses a fan to drive an extraction pipe to extract the waste gas generated during stirring, and then introduces the gas into the interior of a water tank. The waste gas passes through the water tank, where the water removes particulate impurities and some soluble gases. Then, through the exhaust pipe, the gas passes through multiple activated carbon plates inside, where it is adsorbed and filtered again, thereby improving the waste gas purification effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides the following technical solution: Example 1 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A bidirectional stirring device for an aluminum alloy refining furnace includes a base 1, a stirring mechanism 2 is provided on the top of the base 1, and an exhaust mechanism 3 is provided on the bottom of the base 1. The stirring mechanism 2 includes a furnace body 21, a furnace cover 22 rotatably connected to the top of the furnace body 21, a motor 23 fixedly connected to the top of the furnace cover 22, a rotating shaft 24 fixedly connected to the output end of the motor 23, a stirring rod 25 and a first synchronous pulley 26 fixedly connected to the outside of the rotating shaft 24, a transmission belt 27 internally connected to the first synchronous pulley 26, a second synchronous pulley 28 internally connected to the transmission belt 27, a connecting rod 29 fixedly connected to the bottom of the second synchronous pulley 28, a first gear 201 fixedly connected to the outside of the connecting rod 29, and a second gear 202 meshing with the outside of the first gear 201.

[0018] The furnace body 21 is rotatably connected to the top of the base 1, and a support frame is fixedly connected to the top of the base 1. One end of the support frame is fixedly connected to one end of the furnace cover 22.

[0019] One end of the rotating shaft 24 passes through the furnace cover 22 and extends into the interior of the furnace body 21, and a support seat is provided at the bottom of the second synchronous wheel 28.

[0020] The second gear 202 is fixedly connected to the outside of the furnace body 21, and multiple stirring rods 25 are provided.

[0021] Through the above technical solution, raw materials are fed into the furnace body 21 through the feed pipe at the top of the furnace cover 22. Then, the motor 23 drives the rotating shaft 24 to rotate, which in turn drives the stirring rod 25 to stir the raw materials inside the furnace body 21. At the same time, when the rotating shaft 24 rotates, it drives the first synchronous pulley 26 on its outside to rotate, which in turn drives the external transmission belt 27 to drive the transmission belt 27. This causes the second synchronous pulley 28 at the other end of the inner side of the transmission belt 27 to rotate. The rotation of the second synchronous pulley 28 drives the connecting rod 29 at its bottom to rotate, which in turn drives the first gear 201 to rotate. The rotation of the second gear 202, which meshes with the first gear 201, is caused by the rotational connection between the bottom of the furnace body 21 and the top of the base 1, and the fixed connection between one end of the furnace cover 22 and the support frame. This allows the furnace body 21 to rotate. Furthermore, the bidirectional rotation of the furnace body 21 and the stirring rod 25 generates a high-intensity shear flow under the bidirectional speed difference, accelerating the diffusion of alloying elements. The bidirectional motion covers the entire area of ​​the furnace body 21, avoiding the local unmelted areas of traditional unidirectional stirring. Only one motor 23 is needed to drive it, reducing energy consumption and cost, thereby improving stirring efficiency.

[0022] Example 2 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the following is obtained: the exhaust mechanism 3 includes a fan 31, one end of the fan 31 is connected to a water tank 32, and one end of the water tank 32 is fixedly connected to an exhaust pipe 33.

[0023] The blower 31 is installed on the top of the furnace cover 22, and an exhaust pipe is installed at one end of the blower 31.

[0024] One end of the exhaust pipe 33 is screwed to a plurality of activated carbon plates 34, which are arranged in a linear array.

[0025] Through the above technical solution, the exhaust gas generated during stirring is extracted by the blower 31 through the exhaust pipe, and then the gas is introduced into the interior of the water tank 32. The exhaust gas passes through the water tank 32, where the water removes particulate impurities and some soluble gases. Then, the gas passes through multiple activated carbon plates 34 inside the exhaust pipe 33, where it is adsorbed and filtered again, thereby improving the exhaust gas purification effect.
