Rapid cooling sintered structure

Abstract

This utility model belongs to the field of metallurgical engineering, specifically a rapid cooling sintering structure, including a machine body. A cooling mechanism is installed inside the machine body, and a transmission frame is fixedly installed inside the machine body. Several first rotating shafts are rotatably connected inside the transmission frame, and a transmission belt is mounted on the surface of the several first rotating shafts. By setting up the cooling mechanism, a high-efficiency heat exchange channel is formed by symmetrically penetrating the sintered ore layer with dual airflows, thereby increasing the cooling intensity. Furthermore, the symmetrical airflow coverage eliminates the temperature gradient caused by unilateral cooling, achieving uniform heat dissipation of the workpiece cross-section and avoiding deformation and cracking caused by thermal stress concentration. By setting up a transmission component, a single power source drives two cooling spiral blades to operate synchronously, while rigid transmission ensures that the speeds of the two fans are completely consistent, improving the uniformity of airflow coverage and eliminating cooling blind spots caused by asynchronous airflow.

Description

Technical Field

[0001] This utility model relates to the field of metallurgical engineering, specifically a rapid cooling sintering structure. Background Technology

[0002] Sintering machines are crucial raw material pretreatment equipment in the modern steel industry. Their core function is to sinter a mixture of iron ore powder, return ore, flux, and fuel that cannot be directly used in blast furnace smelting into artificial lump ore with sufficient strength and ideal metallurgical properties through high-temperature physicochemical reactions caused by ignition and ventilation.

[0003] Currently, most sintering machines in the prior art use direct air cooling during the cooling process. However, due to the short contact time between the airflow and the high-temperature workpiece and insufficient heat exchange, the cooling rate decreases exponentially. At the same time, forced airflow can easily hinder internal heat transfer, causing internal cooling stagnation. Furthermore, the energy consumption of the fan increases dramatically with the increase of cooling intensity. Therefore, a rapid cooling sintering structure is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most sintering machines in the present technology adopt direct air cooling during the cooling process. However, due to the short contact time between the airflow and the high-temperature workpiece and the insufficient heat exchange, the cooling rate decreases exponentially. At the same time, forced airflow can easily hinder the internal heat transfer, causing internal cooling stagnation. Furthermore, the energy consumption of the fan increases dramatically with the increase of cooling intensity. This utility model proposes a rapid cooling sintering structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rapid cooling sintering structure, including a body, a cooling mechanism is provided inside the body, a transmission frame is fixedly installed inside the body, and a plurality of first rotating shafts are rotatably connected inside the transmission frame, and a transmission belt is sleeved on the surface of the plurality of first rotating shafts.

[0006] The cooling mechanism includes a first arc-shaped baffle slidably connected inside the body, and a second arc-shaped baffle slidably connected inside the body. The first arc-shaped baffle and the second arc-shaped baffle are used in conjunction. Rotary rods are rotatably connected to both sides of the body. Spiral blades are fixedly connected to the surface of the rotating rods. A second fixed frame is fixedly connected to the top of the body. A transmission component is provided inside the second fixed frame. The transmission component is used in conjunction with the rotating rods.

[0007] Preferably, the interior of the body is provided with a sliding groove, and the surfaces of the first arc-shaped baffle and the second arc-shaped baffle are fixedly connected with sliders, the surfaces of the sliders being slidably connected to the inner cavity of the sliding groove.

[0008] Preferably, the body has an internal cavity, and several arc-shaped blocks are fixedly connected inside the cavity. The surfaces of the first and second arc-shaped baffles are fixedly connected with sleeve rods, and an inner rod is slidably connected inside the sleeve rods. The inner rods cooperate with the several arc-shaped blocks.

[0009] Preferably, a spring is provided inside the sleeve rod, with one end of the spring fixedly connected to the inside of the sleeve rod and the other end of the spring fixedly connected to one end of the inner rod.

[0010] Preferably, a stop block is fixedly connected inside the sleeve rod, and a protrusion is fixedly connected to one end of the inner rod, with the stop block and the protrusion working together.

[0011] Preferably, the transmission assembly includes a first fixed frame fixedly connected to the surface of the machine body, a first motor fixedly mounted on the top of the first fixed frame, one end of the rotating rod penetrating the machine body and rotatably connected to the inner cavity of the machine body, one end of the rotating rod being fixedly connected to the output end of the first motor, a second rotating shaft being rotatably connected inside the second fixed frame, a first gear being fixedly connected to one end of the rotating rod, and second gears being fixedly connected to both ends of the second rotating shaft, with the surface of the first gear meshing with the surface of the second gear.

[0013] The advantages of this utility model are:

[0014] 1.

Detailed Implementation

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a rapid cooling sintering structure. (Refer to...) Figure 1 and Figure 4A rapid cooling sintering structure includes a body 1, a cooling mechanism 2 is provided inside the body 1, a transmission frame 4 is fixedly installed inside the body 1, a plurality of first rotating shafts 401 are rotatably connected inside the transmission frame 4, and a transmission belt 402 is sleeved on the surface of the plurality of first rotating shafts 401.

[0026] The cooling mechanism 2 includes a first arc-shaped baffle 203 slidably connected inside the body 1, and a second arc-shaped baffle 204 slidably connected inside the body 1. The first arc-shaped baffle 203 and the second arc-shaped baffle 204 work together. Rotating rods 201 are rotatably connected to both sides of the body 1. Spiral blades 202 are fixedly connected to the surface of the rotating rods 201. A second fixed frame 101 is fixedly connected to the top of the body 1. A transmission assembly 3 is provided inside the second fixed frame 101. The transmission assembly 3 works together with the rotating rods 201. By rotating the rotating rods 201 on both sides of the body 1, the rotating rods 201 drive the spiral blades 202 to rotate. The air generated by the rotation of the spiral blades 202 blows to the surface of the first arc-shaped baffle 203. The first arc-shaped baffle 203 transmits the air downwards. The downward air is transmitted to the surface of the second arc-shaped baffle 204. The second arc-shaped baffle 204 then transmits the air upwards, thereby forming a circulating airflow, which cools the sintered workpiece through the circulating airflow.

[0027] Reference Figure 2 and Figure 3 The machine body 1 has a sliding groove 205 inside. The surfaces of the first arc-shaped baffle 203 and the second arc-shaped baffle 204 are fixedly connected to sliders 206. The surface of the sliders 206 is slidably connected to the inner cavity of the sliding groove 205. The stability of the sliders 206 and the sliding groove 205 ensures the position of the first arc-shaped baffle 203 and the second arc-shaped baffle 204 inside the machine body 1, preventing the first arc-shaped baffle 203 from falling out of the machine body 1. It also allows the first arc-shaped baffle 203 and the second arc-shaped baffle 204 to move and adjust the area of ​​the circulating air force, thereby adapting to workpieces of different volumes for more reasonable cooling.

[0028] Reference Figure 4 and Figure 5The body 1 has an internal cavity 207. Several arc-shaped blocks 208 are fixedly connected inside the cavity 207. A sleeve rod 209 is fixedly connected to the surface of both the first arc-shaped baffle 203 and the second arc-shaped baffle 204. An inner rod 210 is slidably connected inside the sleeve rod 209, and the inner rod 210 cooperates with the several arc-shaped blocks 208. A spring 211 is installed inside the sleeve rod 209. One end of the spring 211 is fixedly connected to the inside of the sleeve rod 209, and the other end of the spring 211 is fixedly connected to one end of the inner rod 210. Moving the first arc-shaped baffle 203 and the second arc-shaped baffle 204... The arc-shaped baffle 203 and the second arc-shaped baffle 204 drive the inner rod 210 to move via the sleeve rod 209. When the inner rod 210 moves to the convex surface of the arc-shaped block 208, the inner rod 210 slides into the inner cavity of the sleeve rod 209. When the inner rod 210 slides to the concave surface of the arc-shaped block 208, the spring 211 pushes the inner rod 210 through the stability of the sleeve rod 209, causing the inner rod 210 to slide out of the inner cavity of the sleeve rod 209 and contact the concave surface of the arc-shaped block 208, thereby restricting the position of the first arc-shaped baffle 203 and the second arc-shaped baffle 204 and preventing the first arc-shaped baffle 203 and the second arc-shaped baffle 204 from sliding arbitrarily due to wind force.

[0029] Reference Figure 4 and Figure 5 A stop 212 is fixedly connected inside the sleeve rod 209, and a protrusion 213 is fixedly connected to one end of the inner rod 210. The stop 212 and the protrusion 213 work together. The stability of the stop 212 and the protrusion 213 ensures the position of the inner rod 210 in the inner cavity of the sleeve rod 209, and prevents the spring 211 from completely pushing the inner rod 210 out of the inner cavity of the sleeve rod 209, thus preventing the inner rod 210 from falling out of the inner cavity of the sleeve rod 209.

[0030] Reference Figure 1 and Figure 2 The transmission assembly 3 includes a first fixed frame 301 fixedly connected to the surface of the machine body 1. A first motor 302 is fixedly mounted on the top of the first fixed frame 301. One end of a rotating rod 201 passes through the machine body 1 and is rotatably connected to the inner cavity of the machine body 1. One end of the rotating rod 201 is fixedly connected to the output end of the first motor 302. A second rotating shaft 304 is rotatably connected inside the second fixed frame 101. A first gear 303 is fixedly connected to one end of the rotating rod 201. Second gears 305 are fixedly connected to both ends of the second rotating shaft 304. The surface of 303 meshes with the surface of the second gear 305; the first motor 302 drives the rotating rod 201 on one side of the machine body 1 to rotate, the rotating rod 201 drives the first gear 303 to rotate, the first gear 303 drives the second rotating shaft 304 to rotate through the second gear 305, so that the second rotating shaft 304 drives the first gear 303 on the opposite side to rotate through the second gear 305 on the opposite side, thereby making the rotating rods 201 on both sides rotate simultaneously through a single power, which saves costs and ensures that the spiral blades 202 on both sides rotate in a consistent manner.

[0031] Reference Figure 1 and Figure 2 A third fixed frame 403 is fixedly connected to the surface of the transmission frame 4. A second motor 404 is fixedly installed on the top of the third fixed frame 403. One end of a first rotating shaft 401 passes through the transmission frame 4 and is rotatably connected to the inner cavity of the transmission frame 4. One end of the first rotating shaft 401 is fixedly connected to the output end of the second motor 404. The second motor 404 drives one of the first rotating shafts 401 to rotate, and the first rotating shaft 401 drives the transmission belt 402 to rotate, so that the transmission belt 402 can transport the workpiece to the target position, thereby achieving the purpose of cooling.

[0032] Working principle: The sintered workpiece is placed on the surface of the conveyor belt 402. The second motor 404 is then started, driving one of the first rotating shafts 401 to rotate. This first rotating shaft 401 drives the conveyor belt 402 to rotate, allowing the conveyor belt 402 to transport the workpiece. Simultaneously, the first motor 302 starts after the second motor 404 starts. The first motor 302 drives one rotating rod 201 to rotate, which in turn drives the first gear 303 to rotate. The first gear 303, through the second gear 305, drives the second rotating shaft 304 to rotate. The second rotating shaft 304 then drives the opposite second gear 305 to rotate, which in turn drives the opposite first gear 303 to rotate, thus enabling the opposite side to move. The first gear 303 drives the opposite rotating rod 201 to rotate, thereby achieving the purpose of simultaneously driving the spiral blades 202 to rotate through the rotating rods 201 on both sides. When the rotating rods 201 on both sides drive the spiral blades 202 to rotate, the rotation of the spiral blades 202 generates wind force. The spiral blades 202 blow the wind to the surface of the first arc-shaped baffle 203 inside the machine body 1. The first arc-shaped baffle 203 transmits the wind downward, allowing the wind to pass through the conveyor belt 402 to the surface of the second arc-shaped baffle 212. The second arc-shaped baffle 204 transmits the wind upward again, forming two wind force cycles on both sides of the machine body 1. This symmetrical double-circulation airflow enhances the cooling intensity, reduces the workpiece temperature, and allows the workpiece to dissipate heat evenly, avoiding deformation and cracking.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
