Description

Technical Field

[0001] This invention relates to the field of sintering machine trolley sealing technology, and more specifically, to a sintering machine fitting flexible sealing structure and method thereof. Background Technology

[0002] During the operation of the sintering machine, the sealing of the gap between the trolley and the fixed slide is a key factor restricting the system's operating efficiency. Currently, most sintering machine trolleys use rigid seals or a single flexible seal, which generally have many prominent defects: the rigid seals have poor fit with the trolley's elastic sliding plate and the fixed slide, with the gap remaining at 0.5-1.2mm year-round, resulting in an air leakage rate of 30%-40% in the sintering machine system. This not only wastes a lot of blower energy but also causes insufficient local sintering temperature and reduces the yield of sintered ore due to air leakage; conventional flexible seals have insufficient high-temperature resistance, with an average service life of only 6-8 months under the high-temperature operating conditions under the trolley, requiring frequent shutdowns for maintenance and replacement, resulting in high operation and maintenance costs; at the same time, traditional sealing structures are difficult to create stable lubrication conditions, which increases the friction coefficient between the slide and the trolley's elastic sliding plate, which not only aggravates component wear and tear but also further widens the friction gap, exacerbating the air leakage problem. Therefore, developing a new sealing device that integrates high-temperature resistance, low air leakage, and self-lubrication has become a core and urgent need to solve the problems of high energy consumption and high maintenance costs in sintering machine systems.

[0003] The sintering machine trolley flexible sealing device (CN 207777614 U) includes a sintering machine trolley sealing plate, a flexible sealing strip, a sealing strip pressure plate, and a sealing mounting plate. The patented trolley sealing plate is installed at the position of the sintering machine trolley's sealing elastic sliding plate and needs to be integrally welded to the trolley's upright plate. This patented flexible sealing device is installed at the sintering machine's air box beam, and replacement is simple and requires no modification to the sintering machine itself.

[0004] CN210625350U provides a sealing strip that is easy to install and remove, and a sealing assembly for sealing between a sintering machine trolley and a wind box. The assembly includes a sealing slide at the bottom of the sintering machine trolley and a flexible sealing strip at the top of the wind box. The sealing strip and the sealing slide come into contact and seal under negative pressure. The main difference between this patent and this application is that it also includes a mounting box at the top of the wind box. The sealing strip is installed in the mounting box by fitting or interference fit. The sealing strip does not need to be fixed with fasteners such as bolts and screws. Therefore, when replacing the sealing strip, it can be directly taken out from the mounting box, and when installing, the new sealing strip can be directly pressed into the mounting box. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve

[0006] To address the shortcomings and deficiencies of existing technologies, this invention provides a flexible sealing structure and method for sintering machines. The invention aims to overcome the defects of existing sintering machine trolley seals, such as high air leakage rate, short lifespan, and poor lubrication. It provides an adsorption-type sealing device for sintering machines, utilizing the low positive pressure generated by gas disturbance to achieve adsorption sealing. Simultaneously, it promotes the uniform distribution of lubricating oil to form an oil film, solving the technical problems of high air leakage rate, lack of synergistic lubrication, and rapid component wear in existing sealing devices. This achieves the goals of energy saving, consumption reduction, and extended equipment lifespan.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0009] The present invention provides a sintering machine fitting flexible sealing structure, including a sintering machine trolley and a wind box. The side of the wind box is provided with a wind box longitudinal beam, and a fixed slide is provided on the wind box longitudinal beam. An elastic slide is provided on the surface of the fixed slide, and the sintering machine trolley is mounted on the upper part of the elastic slide.

[0010] An adsorption-type flexible sealing body is provided between the longitudinal beam of the wind box and the sintering machine trolley; the adsorption-type flexible sealing body includes a base, a flexible sealing device and a connector, the base is fixed to the longitudinal beam of the wind box, and the flexible sealing device is embedded in the base and fastened by the connector.

[0011] Furthermore, the sintering machine trolley is equipped with wheels on both sides, and the wheels are placed on the track; a track seat is provided at the bottom of the track.

[0012] Furthermore, the flexible sealing device includes a high-temperature resistant layer and a wear-resistant layer. The high-temperature resistant layer is 15-20mm thick and is made of alumina fiber cotton. The wear-resistant layer is 5-8mm thick and is made of silicon carbide coating.

[0013] Furthermore, the base is made of bent steel plate with a U-shaped cross-section, and the flexible sealing device is embedded in the U-shaped groove of the base.

[0014] Furthermore, the flexible sealing device fits into the elastic sliding plate and the fixed sliding track, forming an airflow disturbance A and a low positive pressure region B at the junction of the flexible sealing device, the elastic sliding plate and the fixed sliding track. The positive pressure value of the low positive pressure region B is 50-150 Pa.

[0015] Furthermore, the base is fixed to the lower part of the longitudinal beam of the wind box by welding.

[0016] A method for a sintering machine-fitted flexible sealing structure, comprising the following steps:

[0017] S1: Foundation base cleaning and positioning: Clean the mounting surface under the longitudinal beam of the air box, remove rust, oil, dust and debris from the surface, and ensure that the welding surface is flat and clean; according to the design drawings, use a tape measure and level to determine the installation position of the foundation base, make marks, and ensure that the center line of the foundation base is parallel to the center line of the fixed slide, with an installation deviation of ≤1mm, to avoid the subsequent flexible sealing device not fitting tightly due to positioning deviation;

[0018] S2: Welding and fixing of the base base: Attach the base base to the marked position under the longitudinal beam of the wind box, and use a level to adjust the levelness of the base base to ensure that the horizontal error is ≤1mm / m; Weld the base base to the longitudinal beam of the wind box firmly using full welding, and the welding height is not less than the thickness of the base base. After welding, clean and grind the weld to ensure that the weld is flat and free of sharp protrusions to prevent scratching the flexible sealing device.

[0019] S3: Flexible sealing device assembly: Slowly insert the flexible sealing device into the groove of the base base, avoiding damage to the high-temperature resistant layer and wear-resistant layer of the flexible sealing device; use a feeler gauge to check the gap between the flexible sealing device and the groove, ensuring that the gap is ≤2mm. If the gap is too large, the position of the flexible sealing device needs to be adjusted or a suitable sealing device needs to be replaced; adjust the height of the flexible sealing device to make it precisely fit the contact parts of the elastic slide plate and the fixed slide, with the height error controlled within ±1mm, ensuring that the top of the device can fit against the lower surface of the elastic slide plate and the side surface of the fixed slide, with a fitting gap of ≤1mm;

[0020] S4: Fastening the connectors: Screw the connectors into the preset bolt holes of the base in sequence. After tightening, check whether the connectors are loose or stripped.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0023] 1. To address the potential air leakage between the elastic sliding plate and the fixed slide of the sintering trolley, this invention employs a flexible sealing element that is fitted and arranged on the outside of the elastic sliding plate and the fixed slide. Relying on the flexible sealing structure and the airflow action, a positive pressure air film is formed, which can generate a sealing oil film on the contact surface of the slide and improve lubrication conditions, as well as effectively seal the gap and significantly reduce the air leakage rate of the system.

[0024] 2. This device relies on the longitudinal beam 6 of the wind box as the installation support foundation, which is simple to install. The overall installation layout does not require structural modification of the sintering machine trolley body, fixed slide and elastic slide plate, and does not require modification of the original main equipment. It has strong adaptability and low modification construction cost.

[0025] 3. Due to the good and stable sealing effect of the side seal, the sealing effect will not decrease over time compared with the traditional slide seal, and it can be quickly replaced during maintenance. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0032] Example 1

[0033] from Figure 1-4 As can be seen, the sintering machine fitting flexible sealing structure of this embodiment includes a sintering machine trolley 1 and a wind box 8. Wheels 2 are provided on both sides of the sintering machine trolley 1, and the wheels 2 are placed on the track 4. A track seat 3 is provided at the bottom of the track 4.

[0034] The side of the wind box 8 is provided with a wind box longitudinal beam 6, and a fixed slide rail 5 is provided on the wind box longitudinal beam 6. An elastic slide plate 9 is provided on the surface of the fixed slide rail 5. The elastic slide plate 9 cooperates with the fixed slide rail 5, and the upper part of the elastic slide plate 9 is equipped with a sintering machine trolley 1.

[0035] An adsorption-type flexible sealing body 7 is provided between the longitudinal beam 6 of the wind box and the sintering machine trolley 1; the adsorption-type flexible sealing body 7 includes a base base 71, a flexible sealing device 72 and a connector 73. The base base 71 is fixed to the longitudinal beam 6 of the wind box, and the flexible sealing device 72 is embedded in the base base 71 and fastened by the connector 73.

[0036] The flexible sealing device 72 includes a high-temperature resistant layer 721 and a wear-resistant layer 722. The high-temperature resistant layer 721 is 15-20mm thick and is made of alumina fiber cotton. The wear-resistant layer 722 is 5-8mm thick and is made of silicon carbide coating.

[0037] The base base 71 is fixed to the lower part of the longitudinal beam 6 of the wind box by welding. The base base 71 is made of steel plate bending and has a U-shaped cross section. The flexible sealing device 72 is embedded in the U-shaped groove of the base base 71.

[0038] The flexible sealing device 72 fits tightly against the elastic slide plate 9 and the fixed slide 5, forming an airflow disturbance A and a low positive pressure region B at the junction of the flexible sealing device 72, the elastic slide plate 9 and the fixed slide 5. The positive pressure value of the low positive pressure region B is 50-150 Pa.

[0039] The flexible sealing device is fixed to the longitudinal beam of the wind box by the base. Its composite structure fits tightly with the elastic slide plate of the trolley and the fixed slide, directly and physically sealing the original gap between the two and blocking the main air leakage channel.

[0040] When the sintering machine is running, the airflow in the system flows through the hard cotton structure of the flexible sealing device. Due to the obstruction of the airflow direction, vortices are generated, forming a low positive pressure area of ​​50-150Pa at the joint. This positive pressure creates a "blocking effect" on the external air, preventing air from seeping into the air box from the gap, thus achieving "adsorption" sealing.

[0041] The airflow in the low positive pressure region can drive the diffusion of lubricating oil on the surface of the fixed slide rail 5, allowing the lubricating oil to evenly cover the contact surface between the slide rail and the elastic slide plate, forming a sealing oil film. This oil film not only reduces the coefficient of friction but also fills tiny gaps, working synergistically with the positive pressure air film to further reduce air leakage and minimize component wear. This low positive pressure region, on the one hand, creates a "blocking effect" on external air, effectively inhibiting external airflow from seeping into the air box through the gap between the trolley and the fixed slide rail, achieving an "adsorption" seal and reducing the original gap to ≤1mm, significantly reducing the air leakage rate. On the other hand, the stable airflow in the low positive pressure region ensures the diffusion of high-temperature extreme-pressure lubricating oil on the surface of the fixed slide rail, allowing the lubricating oil to evenly cover the contact surface between the slide rail and the elastic slide plate, forming a sealing oil film with a thickness of 5-10μm. This oil film not only reduces the coefficient of friction between the trolley's elastic slide plate and the fixed slide rail, reducing component wear, but also fills tiny gaps on the contact surface, working in conjunction with the positive pressure air film to further reduce air leakage.

[0042] The positive pressure air film works synergistically to further enhance the sealing effect, achieving a two-way promotion of sealing and lubrication.

[0043] The low positive pressure region formed by gas disturbance is the core of this invention for achieving synergistic "adsorption-type" sealing and lubrication, and its specific function is reflected in two aspects:

[0044] (1) Achieving adsorption sealing: The air pressure in the low positive pressure area is higher than the external atmospheric pressure, which forms a "blocking effect" on the external air, effectively inhibiting the external airflow from seeping into the air box through the gap between the trolley and the fixed slide, blocking the air leakage channel; at the same time, the low positive pressure will press the flexible sealing device tightly against the elastic slide and the fixed slide, further reducing the fitting gap, improving the sealing effect, reducing the original gap to ≤1mm, and significantly reducing the air leakage rate.

[0045] (2) Promote lubrication and oil film formation: The stable airflow in the low positive pressure area will drive the high temperature extreme pressure lubricating oil on the surface of the fixed slide to diffuse, so that the lubricating oil evenly covers the contact surface between the slide and the elastic slide, forming a sealing oil film with a thickness of 5-10μm; the oil film can not only reduce the friction coefficient between the trolley elastic slide and the fixed slide, reduce component wear, but also fill the tiny gaps in the contact surface. It works synergistically with the air film formed by the low positive pressure to further improve the sealing effect, achieve two-way promotion of sealing and lubrication, and extend the service life of the equipment.

[0046] Example 2

[0047] from Figure 1-4 As can be seen, the method for a sintering machine bonding flexible sealing structure in this embodiment includes the following steps:

[0048] S1: Cleaning and positioning of the foundation base 71: Clean the mounting surface under the longitudinal beam 6 of the air box, remove rust, oil, dust and debris from the surface, and ensure that the welding surface is flat and clean; according to the design drawings, use a tape measure and level to determine the installation position of the foundation base 71, mark it, and ensure that the center line of the foundation base 71 is parallel to the center line of the fixed slide 5, with an installation deviation of ≤0.3mm, to avoid the subsequent flexible sealing device 72 not fitting tightly due to positioning deviation;

[0049] S2: Welding and fixing of the base base 71: Attach the base base 71 to the marked position at the bottom of the longitudinal beam 6 of the wind box, and use a level to adjust the levelness of the base base 71 to ensure that the horizontal error is ≤0.2mm / m; Weld the base base 71 to the longitudinal beam 6 of the wind box using full welding, and the welding height is not less than the thickness of the base base 71. After welding, clean and grind the weld to ensure that the weld is flat and free of sharp protrusions to prevent scratching the flexible sealing device 72.

[0050] S3: Assembly of flexible sealing device 72: Slowly insert the flexible sealing device 72 into the groove of the base base 71 to avoid damaging the high-temperature resistant layer 721 and wear-resistant layer 722 of the flexible sealing device 72; use a feeler gauge to check the gap between the flexible sealing device 72 and the groove to ensure that the gap is ≤2mm. If the gap is too large, the position of the flexible sealing device 72 needs to be adjusted or a suitable sealing device needs to be replaced; adjust the height of the flexible sealing device 72 to make it precisely fit the contact parts of the elastic slide plate 9 and the fixed slide 5. The height error is controlled within ±1mm to ensure that the top of the device can fit tightly against the lower surface of the elastic slide plate 9 and the side surface of the fixed slide 5, with a fitting gap of ≤1mm;

[0051] S4: Tightening of connector 73: Screw connector 73 into the preset bolt holes of base base 71 in sequence. After tightening, check whether connector 73 is loose or stripped.

[0052] The height design of the adsorption-type flexible seal 7 is adapted to the contact parts of the trolley's elastic slide plate 9 and the fixed slide rail 5 (height error ±1mm), ensuring that the top of the device is tightly attached to the lower surface of the elastic slide plate and the side surface of the fixed slide rail without any obvious gaps; the flexible sealing device 72 is tightly attached to the elastic slide plate 9 and the fixed slide rail 5. Because the high-temperature resistant hard cotton obstructs the airflow direction, an airflow disturbance is formed at the junction of the flexible sealing device, the elastic slide plate and the fixed slide rail, which in turn forms a low positive pressure, promoting the lubrication of the fixed slide rail to generate a sealing oil film and reducing air leakage.

[0053] After the flexible sealing device is installed, its high-temperature resistant hard cotton structure hinders the normal flow direction of airflow in the sintering machine system: an airflow disturbance is formed at the junction of the flexible sealing device, the elastic slide plate and the fixed slide. When the airflow passes through the disturbance, a local vortex is generated, which in turn forms a low positive pressure area (positive pressure value 50-150Pa) at the junction. This low positive pressure can inhibit the external airflow from seeping into the gap, forming an "adsorption" sealing effect. On the other hand, it can promote the uniform distribution of lubricating oil on the surface of the fixed slide 5, forming a sealing oil film C with a thickness of 5-10μm. The oil film and the positive pressure air film work together to further reduce the gap leakage rate.

[0054] The sealing structure of the present invention is used to seal the gap between the sintering machine trolley 1 and the fixed slide rail 5;

[0055] The core of this invention lies in proposing an integrated sealing solution combining physical sealing and adsorption sealing. By designing a flexible sealing device with a high-temperature resistant rigid cotton composite structure and employing a precise installation method, the sealing device's obstruction of airflow generates stable gas disturbance, forming a low positive pressure zone. This not only effectively seals the gaps but also promotes the diffusion of lubricating oil to form a sealing oil film, achieving a two-way synergy between sealing and lubrication. This overcomes the limitation of existing sealing devices that can only achieve a single sealing function. Simultaneously, a standardized installation process and parameter control are defined to ensure the installation accuracy and operational stability of the sealing device, further improving the sealing effect and extending equipment lifespan.

[0056] This invention relates to the field of sintering machine sealing technology, specifically to an adsorption-type sealing method and device for sintering machines. It is suitable for sealing the gap between the sintering machine trolley 1 and the fixed slide rail 5, and is particularly suitable for sintering machine equipment with high requirements for sealing effect and energy saving. It can achieve a synergistic effect of sealing and lubrication, reduce air leakage rate, and extend equipment service life. Specifically, it includes the following innovations:

[0057] 1. To address the potential air leakage between the elastic sliding plate and the fixed slide of the sintering trolley, this invention employs a flexible sealing element that is fitted and arranged on the outside of the elastic sliding plate and the fixed slide. Relying on the flexible sealing structure and the airflow action, a positive pressure air film is formed, which can generate a sealing oil film on the contact surface of the slide and improve lubrication conditions, as well as effectively seal the gap and significantly reduce the air leakage rate of the system.

[0058] 2. This device relies on the longitudinal beam 6 of the wind box as the installation support foundation, which is simple to install. The overall installation layout does not require structural modification of the sintering machine trolley body, fixed slide and elastic slide plate, and does not require modification of the original main equipment. It has strong adaptability and low modification construction cost.

[0059] 3. Due to the good and stable sealing effect of the side seal, the sealing effect will not decrease over time compared with the traditional slide seal, and it can be quickly replaced during maintenance.

[0060] This invention aims to overcome the shortcomings of existing sintering machine trolley seals, such as "high air leakage rate, short lifespan, and poor lubrication," and provides an adsorption-type sealing device for sintering machines. Through a flexible sealing structure and airflow disturbance design, it achieves the synergistic effect of gap sealing, positive pressure gas film formation, and lubrication promotion, significantly reducing the system's air leakage rate.

[0061] This invention optimizes the sealing structure design, proposes a standardized installation process and a sealing and lubrication synergy mechanism, and utilizes the low positive pressure formed by gas disturbance to achieve adsorption sealing. At the same time, it promotes the uniform distribution of lubricating oil to form an oil film, solving the technical problems of high air leakage rate, lack of synergistic lubrication, and rapid component wear in existing sealing devices, thereby achieving the purpose of energy saving, consumption reduction, and extending equipment service life.

[0062] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
