Quickly replaceable barrier seal structure and dismounting method of lower barrier seal

Abstract

This invention belongs to the technical field of sintering sealing equipment, specifically relating to a quick-replaceable baffle sealing structure and a method for disassembling and assembling the lower baffle sealing strip. Because the openings at both ends of the T-shaped slot are located on one side of the lower baffle sealing surface, and the bent insertion section is located at the end of the vertical installation section and communicates with the opening of the lower baffle sealing surface, the sealing strip can be installed and removed through the opening of the lower baffle sealing surface. The sealing element in the lower baffle slot can be replaced without disassembling the upper baffle, greatly shortening the replacement time and reducing the labor intensity of workers, reducing the time to about 10% of the original. Since the sealing strip has a rigid support sleeve at the installation part, and a detachable boss clamping sleeve is provided on the sealing part, the width of the boss clamping sleeve is smaller than the width of the sealing groove. The rigid support sleeve can be directly inserted into the fixing groove, greatly facilitating the disassembly and assembly of the sealing strip.

Description

Technical Field

[0001] This invention belongs to the technical field of sintering sealing equipment, specifically relating to a quick-replaceable baffle sealing structure and a method for disassembling and assembling the lower baffle sealing strip. Background Technology

[0002] The sintering machine is the core equipment in the sintering process of iron and steel metallurgy, and the sintering trolley is the key carrier for material feeding, ignition, high-temperature reaction, and finished product transportation. During the operation of the sintering machine, the gaps between the trolley baffles are one of the main areas of air leakage. Air leakage in these gaps directly leads to insufficient negative pressure in the sintering machine, uneven sintering, increased energy consumption, and increased fan load, seriously affecting the output, quality, and overall energy efficiency of sintered ore. Therefore, effectively sealing the gaps in the trolley baffles is an important technical step to improve the stability of the sintering process, reduce energy consumption, and improve environmental protection indicators.

[0003] One sealing method involves using a "T-shaped groove + sealing strip" to seal the gaps in the sintering trolley's side panels. This structure creates a groove on the side of the side panel, into which the sealing strip is snapped in. The elasticity of the sealing strip fills the gaps in the side panels, creating a dynamic seal. While the groove-type seal is simple in structure and low in cost, it has gradually revealed significant technical shortcomings under long-term combined conditions of high temperature, dust, impact, and reciprocating friction, leading to a decline in its actual effectiveness.

[0004] The main problems are reflected in the following aspects: 1. Difficult to install The sealing strip and the groove are mostly interference fit, and the groove is prone to deformation and warping due to long-term exposure to high temperature baking and material flow impact. At the same time, sintering dust and slag easily accumulate in the groove, resulting in a reduction in groove size and uneven inner wall, making it difficult to install the sealing strip smoothly. During the installation process, external force such as pry bars and hammers are often used to forcefully squeeze it, which is not only labor-intensive, but also prone to tearing, breaking or deforming of the sealing strip or sealing structure.

[0005] 2. Difficult to replace, long maintenance cycle Dust and clumps accumulate in the slot, forming a monolithic structure that prevents the sealing strip from being quickly removed. Removal often requires cleaning the slot and repeated prying, which is time-consuming due to the narrow operating space and extended downtime of the sintering machine, affecting production continuity.

[0006] 3. Structural damage exacerbates equipment safety hazards. Frequent use of violent disassembly and assembly methods can easily further damage the baffle plate slots and surrounding structures, reduce sealing accuracy, and exacerbate air leakage, thereby affecting the overall lifespan and operational stability of the sintering machine.

[0007] Therefore, there is an urgent need to develop a barrier sealing structure that is easy to replace. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of existing T-shaped groove sealing technology for sintered baffle gaps, and to provide a quick-replaceable baffle sealing structure and a method for disassembling and assembling the lower baffle sealing strip, thereby solving the technical problems of existing T-shaped groove seals being difficult to install, difficult to replace, and prone to damaging the sealing components and groove mechanism.

[0009] The technical problem to be solved by the present invention is achieved by the following technical solution: a quick-replaceable baffle sealing structure, including a lower baffle and a sealing strip; The lower panel is provided with a T-shaped slot, and the openings at both ends of the T-shaped slot are located on one side of the sealing surface of the lower panel. The T-shaped slot includes a fixing slot and a sealing slot. The fixing slot includes a vertical installation section and a bent insertion section. The bent insertion section is located at the end of the vertical installation section and communicates with the opening of the sealing surface of the lower panel. The sealing strip has a T-shaped cross-section and includes an installation part and a sealing part. The installation part is provided with a rigid support sleeve, which is installed in a fixing groove. The sealing part is detachably provided with a boss clamping sleeve, the width of which is smaller than the width of the sealing groove; The sealing part is located inside the sealing groove and protrudes from the sealing surface of the lower panel.

[0010] Preferably, the rigid support sleeve has an extended bend at its end, which can be folded and bent. After the sealing strip is inserted into the T-shaped groove, the extended bend is folded and bent to seal the entrance of the T-shaped groove, greatly reducing the amount of dust entering the gap between the sealing strip and the T-shaped groove, and also reducing the possibility of air leakage.

[0011] Preferably, the extended bending portion of the present invention is provided with a hook mounting hole, so that when the sealing strip is difficult to remove, the sealing strip can be pulled out of the T-shaped groove by means of the long-handled iron hook corresponding to the hook mounting hole.

[0012] Preferably, the rigid support sleeve is provided with an anti-detachment burr on its inner side, and the anti-detachment burr is inserted into the mounting part to enhance the connection strength between the sealing strip and the rigid support sleeve.

[0013] Preferably, the lower guardrail is provided with an upper guardrail at its upper end, so that the upper guardrail does not need to be removed during the installation and removal of the sealing strip.

[0014] Preferably, the bent insertion section of the present invention has an arc-shaped structure and is tangent to the vertical installation section, thereby reducing the resistance of the sealing strip during installation and disassembly.

[0015] This invention also discloses a method for disassembling and assembling a lower panel sealing strip, utilizing the aforementioned quick-replacement panel sealing structure, comprising the following steps: Align one end of the sealing strip with the sealing boss pressing sleeve with the opening at one end of the T-shaped groove, slide the rigid support sleeve in the fixed groove, and insert the sealing strip into the T-shaped groove with arcs at both ends. Installation can be completed by removing the boss clamping sleeve of the sealing part.

[0016] In a preferred embodiment of the present invention, during disassembly, the sealing strip can be pulled out from the T-shaped slots at both ends by pulling one end of the rigid support sleeve.

[0017] The core innovation of this invention lies in: 1. The original straight T-shaped slot was redesigned with bent ends, allowing the sealing strip to be installed and removed from the sealing surface of the lower panel. This solved the problem of replacing the sealing strip in the slot of the lower panel without removing the upper panel, greatly shortening the replacement time and reducing the labor intensity of workers.

[0018] 2. A rigid support sleeve provides rigid support for the original flexible seal, which facilitates the installation and removal of the seal.

[0019] 3. The design of the boss compression sleeve makes full use of the good elasticity of the original flexible seal, compressing the sealing part of the seal to a width smaller than the sealing groove, which facilitates the installation and removal of the sealing strip and prevents the risk of tearing the sealing strip by pulling it directly into the T-shaped slot.

[0020] Compared with the prior art, the beneficial effects of the present invention are: Because the openings at both ends of the T-shaped groove are located on one side of the sealing surface of the lower panel, and the bent insertion section is located at the end of the vertical installation section and communicates with the opening of the sealing surface of the lower panel, the sealing strip can be installed and removed through the opening of the sealing surface of the lower panel. This allows for the replacement of the sealing components in the groove of the lower panel without disassembling the upper panel, significantly shortening replacement time and reducing worker workload by approximately 10% of the original time. Furthermore, the sealing strip has a rigid support sleeve at the installation part, and a detachable boss clamping sleeve is provided on the sealing part. The width of the boss clamping sleeve is smaller than the width of the sealing groove, allowing the rigid support sleeve to be directly inserted into the fixing groove, greatly facilitating the installation and removal of the sealing strip.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0023] like Figures 1-3 As shown, a quick-replaceable baffle sealing structure includes a lower baffle 1 and a sealing strip 2. The sealing strip 2 is made of a high-temperature resistant composite material and is elastic.

[0024] The lower panel 1 is provided with a T-shaped groove 11, and the openings at both ends of the T-shaped groove 11 are located on one side of the sealing surface of the lower panel 1. The cross-section of the T-shaped groove 11 is T-shaped.

[0025] The T-shaped slot 11 includes a fixing slot 111 and a sealing slot 112 arranged perpendicularly to each other. The fixing slot 111 includes a vertical installation section 100 and a bent insertion section 200. The bent insertion section 200 is located at the end of the vertical installation section 100 and communicates with the opening of the sealing surface of the lower panel 1.

[0026] The sealing strip 2 has a T-shaped cross-section and includes an installation part 21 and a sealing part 22 arranged perpendicularly to each other. The installation part 21 is provided with a rigid support sleeve 3, which is installed in the fixing groove 111.

[0027] A boss clamping sleeve 4 is detachably provided on the sealing part 22. The width of the boss clamping sleeve 4 is smaller than the width of the sealing groove 112. The boss clamping sleeve 4 is fitted onto the sealing boss of the sealing element, i.e., the sealing part 22, to flatten the sealing part 22. The width of the boss clamping sleeve 4 is 1mm-2mm smaller than the width of the sealing groove 112 of the T-shaped slot to facilitate the installation of the sealing element. Its material is hard plastic or stainless steel, with a thickness of 0.5mm-1.5mm. After the sealing element is installed on the T-shaped slot, the boss clamping sleeve 4 can be removed.

[0028] The sealing part 22 is located in the sealing groove 112 and protrudes from the sealing surface of the lower guardrail 1, thereby forming a sealing structure with the sealing surface of the lower guardrail 1 on one side of the docking trolley.

[0029] The rigid support sleeve 3 has an extension bend 31 at its end, which can be folded and bent. The rigid support sleeve 3 is made of 0.5mm-2mm thick stainless steel plate, which is 20mm-40mm longer than the sealing strip. The stainless steel plate can be folded to form the extension bend 31. The extension bend 31 can fix the sealing strip to the sealing surface of the lower panel and prevent the sealing strip from falling off when the trolley is turned over. It can also prevent dust from falling into the gap between the T-shaped groove and the rigid support sleeve 3 and prevent air leakage. It also provides a handle for removing the sealing element.

[0030] Place the sealing strip in the center of the stainless steel plate, then roll up both sides of the stainless steel plate and press them firmly onto the two protrusions at the bottom of the sealing strip to provide rigid support for the sealing strip. Cut the part of the stainless steel plate that is longer than the sealing strip along the fold line. After installing the sealing strip on the slot, fold the excess stainless steel plate in the opposite direction to the sealing strip and press it onto the surface of the baffle or the trolley guard plate. This will not only fix the sealing strip on the T-shaped slot and prevent the seal from falling off when the trolley is tilted, but also prevent dust from falling into the gap between the T-shaped slot and the rigid support of the seal, and prevent air from leaking in.

[0031] The extended bending portion 31 is provided with 2-4 hook mounting holes 311.

[0032] The rigid support sleeve 3 is provided with an anti-splurge 32 on its inner side, and the anti-splurge 32 is inserted into the mounting part 21.

[0033] The lower sideboard 1 is provided with an upper sideboard 5 at its upper end. The lower sideboard 1 is installed on the bottom plate of the trolley, and the upper sideboard 5 is installed on the lower sideboard 1.

[0034] The bent insertion section 200 has an arc-shaped structure and is tangent to the vertical installation section 100.

[0035] A method for disassembling and assembling a lower panel sealing strip, utilizing the quick-replaceable panel sealing structure of this embodiment, includes the following steps: Align one end of the sealing strip 2, which is fitted with the sealing protrusion pressing sleeve 4, with the opening at one end of the T-shaped groove 11. The rigid support sleeve 3 slides within the fixing groove 111, and the sealing strip 2 is inserted into the T-shaped groove 11 with arcs at both ends. Fold the stainless steel plates extending from both ends of the sealing strip in the opposite direction and press them onto the surface of the guardrail or the trolley guard plate.

[0036] Installation can be completed by removing the boss clamping sleeve 4 of the sealing part 22.

[0037] During disassembly, fold the stainless steel plate that is pressed against the surface of the guardrail or the trolley guardrail back to a state similar to the initial state. Cut off the stainless steel plate that protrudes from the surface of the guardrail at one end of the seal with a cutting machine. Use pliers or other clamping tools to pull one end of the rigid support sleeve 3 to pull the sealing strip 2 out from the T-shaped grooves 11 at both ends. If it is difficult to pull the sealing strip out by hand, use a long-handled iron hook to hook the hook mounting hole 311 on the sealing strip and pull the sealing strip out of the T-shaped groove 11.
