Description

Technical Field

[0001] This application relates to the field of sintering machine equipment technology, and in particular to a sealing device with a support roller. Background Technology

[0002] During the operation of the sintering machine, the sealing performance of the head and tail sections of the trolley is crucial when it runs in the sealing section. Good sealing performance can effectively reduce airflow leakage in the air box, improve sintering efficiency, and reduce energy consumption. Existing sealing devices at the head and tail of the sintering machine trolley's sealing section avoid problems such as poor sealing effect and poor conveying stability during transportation and support. However, the existing sealing devices use ordinary springs on the output rollers to prevent deformation of the track during use. Furthermore, these springs need to be fixed one by one to the conveyor rollers, making installation and disassembly cumbersome. Utility Model Content

[0003] To solve the problem of cumbersome installation and removal of springs on traditional conveyor rollers, this utility model provides a sealing device with a support roller, suitable for installation at the head and tail of the sealing section of a sintering machine trolley. An air box is provided between the head and tail of the sealing section of the sintering machine trolley. The device is characterized by comprising: Support frame, conveyor rollers, and conveyor belt; The bracket is a hollow structure with an open top, suitable for installation at the output or input end of the sintering machine trolley; The conveyor track includes conveyor rollers and a conveyor track. There are multiple conveyor rollers, which are rotatably arranged inside the bracket and are suitable for driving connection with a drive device. The conveyor track is sleeved on the multiple conveyor rollers. The conveying roller includes a support roller and a support spring. The support roller is a columnar structure and is rotatably disposed inside the bracket. The support spring is annular and is fixedly connected to the outside of the support roller, and the support spring protrudes in a direction away from the support roller.

[0004] In one possible implementation, there are multiple support springs, which are equally spaced along the circumferential direction of the support roller.

[0005] In one possible implementation, there are multiple support springs, spaced apart along the length of the support roller.

[0006] In one possible implementation, any two adjacent support springs are staggered.

[0007] In one possible implementation, the support spring includes a fixing part and a supporting part; The fixing part is a plate with an arc-shaped structure, which fits against the surface of the support roller; The support part has a concave cross-section and its edge is connected to the fixing part.

[0008] In one possible implementation, the support portion protrudes away from the support roller, and the support portion is arc-shaped with an arc degree in the range of 80 to 90 degrees.

[0009] In one possible implementation, the plate surface of the fixing part has a fixing hole, and the support spring is bolted to the support roller.

[0010] In one possible implementation, the cross-sectional length of the support portion is greater than the cross-sectional length of the fixing portion.

[0011] In one possible implementation, the edges of a plurality of staggered support springs are arranged in a circular pattern along the axial length of the support roller.

[0012] In one possible implementation, the support spring is made of an elastic material.

[0013] The beneficial effects of the sealing device with support rollers in this application embodiment are as follows: By designing the support rollers as columnar structures and covering them with annular protruding support springs, combined with the conveyor belts fitted on them, a stable conveying and sealing structure is formed. When the sintering machine trolley enters the sealing section, the high-temperature resistant sealing strip of the head sealing device is in close contact with the sintering machine trolley beam under the pressure of the sintering machine trolley beam. It moves synchronously under the pressure and thrust of the sintering machine trolley. Any part of the outer edge of the front and rear conveyor rollers deforms with the shape change of the sintering machine trolley beam due to the pressure of the sintering machine trolley beam. The conveyor belt always maintains close contact with the sintering machine trolley beam, achieving a 100% sealing effect. When the sealing section ends, the conveyor belt of the tail sealing device naturally separates from the sintering machine trolley in a rolling manner, and the elastic bodies on the front and rear conveyor rollers of the tail sealing device return to their original shape. Two staggered support springs can be covered with protrusions in the circumferential direction of the support roller to play the role of spring support. Compared with the conventional springs set on the support shaft, the support spring of this application is an integral structure, which facilitates the fixing of the support spring and the support roller. Moreover, the support spring is a ring-shaped plate structure with protrusions and is made of elastic material, which is not easily damaged compared with ordinary springs.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0022] Figures 1-4 A schematic diagram of the main structure according to an embodiment of this application is shown. Figure 1 As shown, the sealing device with support rollers in this embodiment includes: a bracket 100, a conveyor roller 200, and a conveyor belt 300. The bracket 100 is a hollow structure with an open top, suitable for installation at the output or input end of a sintering machine trolley. The conveyor belt includes conveyor rollers 200 and conveyor belt 300. There are multiple conveyor rollers 200, which are rotatably installed inside the bracket 100 and are suitable for driving connection with a drive device. The conveyor belt 300 is sleeved on the multiple conveyor rollers 200. Each conveyor roller 200 includes a support roller 210 and a support spring 220. The support roller 210 is a columnar structure and is rotatably installed inside the bracket 100. The support spring 220 is annular and is fixedly connected to the outside of the support roller 210, and the support spring 220 protrudes in a direction away from the support roller 210.

[0023] In this specific embodiment, by designing the support roller 210 as a columnar structure and covering it with an annular protruding support spring 220, combined with the conveyor track 300 fitted on it, a stable conveying and sealing combination structure is formed. When the sintering machine trolley enters the sealing section, the high-temperature resistant sealing strip of the head sealing device is in close contact with the sintering machine trolley beam under the pressure of the sintering machine trolley beam and naturally moves synchronously under the pressure and thrust of the sintering machine trolley. Any part of the outer edge of the front and rear conveyor rollers 200 deforms with the shape change of the sintering machine trolley beam due to the pressure of the sintering machine trolley. The conveyor track 300 always maintains close contact with the sintering machine trolley beam, achieving a 100% sealing effect. When the sealing section ends, the conveyor track 300 of the tail sealing device naturally separates from the sintering machine trolley in the form of rolling, and the elastic bodies on the front and rear conveyor rollers 200 of the tail sealing device return to their original shape. Specifically, the two staggered support springs 220 can be covered with protrusions in the circumferential direction of the support roller 210 to play the role of spring support. Compared with the conventional springs set on the support shaft, the support spring 220 of this application is an integral structure, which facilitates the fixing of the support spring 220 and the support roller 210. Moreover, the support spring 220 is a ring-shaped plate structure with protrusions and is made of elastic material, which is less prone to damage than ordinary springs.

[0024] Specifically, there are two sealing devices with support rollers 210, which are respectively set at the head and tail of the sealing section of the sintering machine trolley. The support rollers 210 serve as the main support and rotating components, and the support springs 220 are sleeved on the outside of them and protrude, so that they can make better contact with the conveyor belt 300 during the conveying process, increase the contact area, improve the stability of the conveying, and at the same time enhance the sealing performance of the device and reduce the leakage of airflow in the air box.

[0025] In one specific embodiment, there are multiple support springs 211, which are equally spaced along the circumferential direction of the support roller 210. The multiple support parts 211 of the support spring 220 are equally spaced along the circumferential direction of the support roller 210, so that the support force is evenly distributed in the circumferential direction, avoiding local wear or deviation of the conveyor belt 300 due to uneven force, and ensuring the stability of the conveying process.

[0026] In one specific embodiment, multiple support springs 220 are spaced apart along the length of the support roller 210, which allows for a more reasonable distribution of the support force along the length of the support roller 210. This better adapts to the force requirements of the conveyor belt 300 in the length direction and enhances the fit between the conveyor belt 300 and the support roller 210.

[0027] In one specific embodiment, any two adjacent support springs 220 are staggered. The staggered arrangement of adjacent support springs 220 can avoid the superposition of support forces in local areas to form stress concentration, reduce the impact load when the conveyor track 300 contacts the support springs 220, reduce the wear rate of both, and make the support force distribution more dispersed.

[0028] In one specific embodiment, the support spring 220 includes a fixing part 212 and a support part 211. The fixing part 212 is an arc-shaped plate that conforms to the surface of the support roller 210. The arc-shaped plate structure of the fixing part 212 conforms to the surface of the support roller 210, ensuring a firm and reliable connection between the support spring 220 and the support roller 210, preventing the support spring 220 from loosening or falling off during operation. The support part 211 has a concave cross-section and its edge connects to the fixing part 212. The concave cross-section of the support part 211 enhances the elasticity and support strength of the support spring 220, providing better support for the conveyor belt 300. At the same time, the concave structure also helps to distribute stress and improve the durability of the support spring 220.

[0029] In one specific embodiment, the support portion 211 protrudes away from the support roller 210, and the support portion 211 is arc-shaped with an arc degree between 80 and 90 degrees. The protrusion of the support portion 211 away from the support roller 210 allows for better contact with the conveyor belt 300, increasing the contact area and improving the support effect. Limiting the arc degree of the support portion 211 to the 80-90 degree range has been verified through extensive experiments. This arc degree range allows the support portion 211 to provide sufficient support force while maintaining good elasticity, preventing damage or poor support effect caused by an unsuitable arc degree.

[0030] In one specific embodiment, the plate surface of the fixing part 212 is provided with fixing holes, and the support spring 211 is bolted to the support roller 210.

[0031] In one specific embodiment, the cross-sectional length of the support portion 211 is greater than the cross-sectional length of the fixing portion 212, which allows the support portion 211 to have a larger contact area with the conveyor track 300, thereby improving the stability and reliability of the support.

[0032] In one specific embodiment, along the axial length of the support roller 210, the edges of multiple staggered support springs 220 are circular, which makes the contact between the support roller 210 and the conveyor belt 300 more stable during rotation, avoiding vibration or wear of the conveyor belt 300 due to irregular edge shapes.

[0033] In one specific embodiment, the support spring 220 is made of an elastic material, which gives it good elastic deformation capability. When the conveyor track 300 is subjected to pressure or impact during operation, the support spring 220 can undergo corresponding elastic deformation, playing a role in buffering and shock absorption, reducing damage to the conveyor track 300 and the support roller 210. At the same time, the elastic material of the support spring 220 can better adapt to the shape changes of the conveyor track 300, ensuring close contact between the two, improving sealing performance and conveying stability.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
