Description

Technical Field

[0001] This utility model belongs to the field of sintering technology, specifically, it relates to a vertical cooling kiln for sintering. Background Technology

[0002] A document with publication number (CN203719428U) discloses a feed hopper for a vertical cooling kiln, which includes an outer protective plate and an inner lining plate attached to the inner surface of the outer protective plate. The feed hopper of the vertical cooling kiln described above has good wear resistance, a long service life, is easy to inspect and maintain, and has low maintenance costs.

[0003] The aforementioned device reduces the friction of sinter by using a conical design and finned plates. However, in actual use, extremely high friction still exists, affecting the device's operation. Furthermore, the direct discharge of sinter into the device causes damage during impact, affecting the quality of the sinter.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To address the technical problems related to sintered ore emissions, the basic concept of the technical solution adopted in this utility model is as follows:

[0006] A vertical cooling kiln for sinter includes a buffer assembly for buffering the sinter. The buffer assembly includes a tube body, a buffer block, a mounting block, and a buffer ball. Multiple sets of tube bodies are provided and connected to each other by fasteners. The mounting block is disposed on the inner wall of the corresponding tube body, and the buffer ball is disposed around the mounting block. The corresponding buffer block is connected to the mounting block.

[0007] In a preferred embodiment of the present invention, the mounting block is generally annular, and the ends of the mounting block are inclined, with the buffer ball connected to the inclined surface of the mounting block through a ball-and-socket structure.

[0008] In a preferred embodiment of the present invention, each of the mounting blocks is fixedly connected to a blocking block, the blocking block being in the shape of an inverted L, and the end of the blocking block not completely blocking the buffer ball.

[0009] In a preferred embodiment of this utility model, each of the shielding blocks is fixedly connected with an air cushion, which is ring-shaped and not filled with gas.

[0010] In a preferred embodiment of the present invention, each air cushion is fixedly connected to a buffer block, each buffer block is slidably connected to a shielding block, and the bottom of the mounting block is threadedly connected to an assembly block, which is fixedly connected to the inner wall of the tube.

[0011] In a preferred embodiment of this utility model, each of the tubes is fixedly connected to an inner cylinder, and there is a cavity between the inner cylinder and the tube body, in which a condenser tube is fixedly connected.

[0012] In a preferred embodiment of this utility model, each inner cylinder is surrounded by a flow divider plate, and the flow divider plates are arranged in multiple layers with staggered arrangement between the layers. Each flow divider plate is fixedly installed to the inner wall of the inner cylinder.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This vertical cooling kiln for sintered ore uses a structure within a buffer assembly to initially buffer the sintered ore. As the sintered ore falls, it comes into contact with a buffer ball. The buffer ball is connected to the inclined surface at the end of the mounting block. After the buffer ball contacts the sintered ore, it rotates due to the force of the falling sintered ore. During rotation, the friction between the sintered ore and the inner wall of the tube is reduced. Furthermore, the inclined surface at the end of the mounting block disperses the force, reducing the force applied to the mounting block and preventing damage to the quality of the sintered ore.

[0015] 2. In this vertical cooling kiln for sintered ore, after the sintered ore passes through the inner cylinder area, it is blocked by the diversion plates installed inside the inner cylinder. Due to the inclined and layered staggered arrangement of the diversion plates, the falling speed of the sintered ore is buffered. After being buffered by the mounting blocks and the components on the mounting blocks, the falling force of the sintered ore is not large. The condensing pipes inside the inner cylinder and the tube cavity work continuously to continuously cool the area inside the inner cylinder. Through the cooling of the inner cylinder area, heat is exchanged with the sintered ore, and the cooling of the sintered ore is completed quickly.

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0025] Please see Figure 1-5 A vertical cooling kiln for sinter includes a buffer assembly for buffering the sinter. The buffer assembly includes a tube body 1, a buffer block 2, a mounting block 23, and a buffer ball 24. Multiple sets of tube bodies 1 are provided and connected to each other by fasteners, including but not limited to bolts. The mounting block 23 is disposed on the inner wall of the corresponding tube body 1, and the buffer ball 24 is disposed around the mounting block 23. The corresponding buffer block 2 is connected to the mounting block 23. After the sinter is initially buffered by the structure inside the buffer assembly, the sinter falls and contacts the buffer ball 24. The buffer ball 24 is connected to the inclined surface at the end of the mounting block 23. After the buffer ball 24 contacts the sinter, it rotates due to the force of the falling sinter. During the rotation, the friction between the sinter and the inner wall of the tube body 1 is reduced. The force is dispersed by the inclined surface at the end of the mounting block 23, reducing the force applied to the mounting block 23 and avoiding damage to the quality of the sinter.

[0026] The mounting block 23 is generally annular, with its ends inclined. The buffer ball 24 is connected to the inclined surface of the mounting block 23 via a ball-and-socket structure. Each mounting block 23 is fixedly connected to a blocking block 22, which is generally inverted L-shaped, but its ends do not completely block the buffer ball 24. Each blocking block 22 is fixedly connected to an air cushion 21, which is annular and not fully filled with gas. Each air cushion 21 is fixed with... A buffer block 2 is connected, and each buffer block 2 is slidably connected to a shielding block 22. An assembly block 25 is threadedly connected to the bottom of the mounting block 23. The assembly block 25 is fixedly connected to the inner wall of the pipe body 1. When the sintered ore enters from the port of the pipe body 1, some of the sintered ore comes into contact with the buffer block 2. The buffer block 2 is impacted by the sintered ore and presses down on the air cushion 21. The air cushion 21 deforms and absorbs and buffers the impact force through deformation, thereby canceling the force. After the sintered ore falls, the air cushion 21 returns to its original position after deformation. The air cushion 21 moves upward, causing the buffer block 2 to reset, thus completing the subsequent buffering effect on the sinter. The sinter contacts the buffer ball 24 as it falls. The buffer ball 24 is connected to the inclined surface at the end of the mounting block 23. After the buffer ball 24 contacts the sinter, it rotates due to the force of the falling sinter. During the rotation, the friction between the sinter and the inner wall of the pipe body 1 is reduced. The force is dispersed through the inclined surface at the end of the mounting block 23, reducing the force applied to the mounting block 23 and preventing damage to the quality of the sinter. After the mounting block 23 and its components are damaged, the threaded connection between the mounting block 23 and the assembly block 25 makes it easy for workers to rotate and disassemble the mounting block 23 and the assembly block 25, and install the new mounting block 23 and the assembly block 25 by rotating the threaded connection. This allows for quick replacement of internal components. The segmented design of the pipe body 1 makes it easy to disassemble and replace the whole structure.

[0027] It is worth noting that this optimization scheme is aimed at the structural optimization of the inner wall of the vertical cooling kiln pipe. Therefore, the remaining structures inside the vertical cooling kiln are not described in detail, and these structures are well-known technologies in the field, so they will not be described here.

[0028] Each tube 1 is fixedly connected to an inner cylinder 3. There is a cavity between the inner cylinder 3 and the tube 1. A condenser pipe 31 is fixedly connected inside the cavity. Each inner cylinder 3 is surrounded by a multi-layered diverter plate 32, which is staggered between the layers. Each diverter plate 32 is fixedly installed to the inner wall of the inner cylinder 3. After the sintered ore passes through the area of ​​the inner cylinder 3, it is blocked by the diverter plate 32 inside the inner cylinder 3. Due to the inclined and staggered arrangement of the diverter plate 32, the falling speed of the sintered ore is buffered. After being buffered by the mounting block 23 and the components on the mounting block 23, the falling sintered ore does not have a large force. The condenser pipe 31 inside the inner cylinder 3 and the tube 1 cavity works continuously to continuously cool the area inside the inner cylinder 3. The cooling of the area inside the inner cylinder 3 exchanges heat with the sintered ore, and the sintered ore is cooled quickly.

[0029] Working principle: When sintered ore enters from the port of pipe body 1, some of the sintered ore comes into contact with buffer block 2. The impact of the sintered ore on buffer block 2 causes the air cushion 21 to deform, absorbing and buffering the impact force. After the sintered ore falls, the air cushion 21 returns to its original position and moves the buffer block 2 upwards. This upward movement of the air cushion 21 further resets the buffer block 2, completing the subsequent buffering effect on the sintered ore. During its fall, the sintered ore contacts the buffer ball 24. Because the buffer ball 24 is connected to the inclined surface of the mounting block 23, it rotates due to the force of the falling sintered ore. This rotation reduces the friction between the sintered ore and the inner wall of pipe body 1. Furthermore, the inclined surface at the end of the mounting block 23 disperses the force, reducing the force applied to the mounting block 23 and preventing damage to the quality of the sintered ore. After the mounting block 23 and its components are damaged, the threaded connection between the mounting block 23 and the assembly block 25 allows workers to easily rotate and disassemble the mounting block 23 and the assembly block 25, and then install the new mounting block 23 and the assembly block 25 by rotating them together. This allows for quick replacement of internal components. The segmented design of the tube body 1 also facilitates the overall disassembly and replacement. After the sintered ore passes through the inner cylinder 3 area, it is blocked by the diversion plate 32 set inside the inner cylinder 3. Due to the inclined and staggered arrangement of the diversion plate 32, the falling speed of the sintered ore is buffered. Because of the buffering effect of the mounting block 23 and its components, the falling sintered ore does not have a large force. The condenser pipe 31 inside the inner cylinder 3 and the tube body 1 continues to work, continuously cooling the area inside the inner cylinder 3. The cooling of the inner cylinder 3 area exchanges heat with the sintered ore, quickly completing the cooling of the sintered ore.
