Description

Technical Field

[0001] This utility model relates to the field of environmental protection sealing auxiliary equipment technology, and in particular to a high-temperature resistant and ductile dust removal cover sealing device for the tail end of a coke grid. Background Technology

[0002] For a long time, coke oven production has often been accompanied by large amounts of smoke and fire. While a series of dust removal upgrades to coke oven processes, such as coke discharge dust removal, coal feeding dust removal, and coke pushing dust removal, have greatly improved the environment, significant amounts of fugitive emissions still exist. During the coke receiving process, the coke guide grid of the coke quenching car needs to extend and rigidly seal against the oven door frame during coke pushing. The gaps at the connection between the tail of the guide grid and the dust collector hood are large, and since the guide grid is a moving mechanism while the dust collector hood is a fixed mechanism, a rigid connection is not possible. These large voids and gaps over time lead to a significant loss of suction power during coke discharge dust removal. During coke pushing, thermal buoyancy carries coke powder and flue gas, causing a large amount of coke powder to escape through these gaps. This results in severe coke powder accumulation in the operating mechanisms and electrical facilities of the coke grid platform, easily reducing the lifespan of rotating equipment and causing short circuits and burnouts. Furthermore, the high temperature, high impact, and frequent operation of the dust collector hood at the tail of the coke grid make it unsuitable for currently available flexible sealing devices. Therefore, the fugitive emission of smoke and dust at the connection between the coke grid and the dust collector hood during coke discharge has not been effectively addressed. Utility Model Content

[0003] The problem to be solved by this utility model is to provide a high-temperature resistant, ductile dust collector sealing device that can flexibly seal the gap between the movable part of the coke grid tail and the dust collector hood, effectively improving the sealing performance.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: This high-temperature resistant and ductile coke oven tail dust collector sealing device includes an adjusting base, which is a high-temperature resistant flame arrestor sleeve. The inner cavity of the high-temperature resistant flame arrestor sleeve is filled with asbestos ceramic fibers to form a high-temperature resistant layer. The high-temperature resistant flame arrestor sleeve has multiple connecting holes. On the front side of the adjusting base, along its length, two connecting plates with an "L"-shaped cross-section and a length equal to that of the high-temperature resistant flame arrestor sleeve are respectively pressed together. Several connecting holes are opened on the connecting plates, corresponding to the positions of the connecting holes on the high-temperature resistant flame arrestor sleeve. On the back side of the adjusting base, two clamping plates are pressed together along its length. Several connecting holes are opened on the clamping plates, corresponding to the positions of the connecting holes on the high-temperature resistant flame arrestor sleeve.

[0005] In the above-mentioned technical solution of the high-temperature resistant and ductile coke grid tail dust collector sealing device, a more specific technical solution may be: the connecting plate is an angle steel, the clamping plate is a flat steel, the hole on one side of the connecting plate and the clamping plate is a positioning hole, the hole on the other side of the connecting plate and the clamping plate is a clamping hole, and the positioning hole and the clamping hole are staggered.

[0006] In some possible implementations, the high-temperature fire-retardant sleeve is formed by welding two long plates together, with a cavity in the middle and open ends, and the asbestos ceramic fibers are filled in the cavity.

[0007] In some possible implementations, bolts are inserted into both the positioning hole and the clamping hole, and are locked in place by nuts.

[0008] In some possible implementations, the side of the adjusting base with the positioning hole is connected and positioned to the dust cover, and the side of the adjusting base with the clamping hole is connected and locked to the coke grid.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0010] 1. This device flexibly seals the gap between the moving parts at the tail of the coke grate and the dust collector hood, effectively improving the sealing performance and thus preventing the escape of flue gas and coke powder, reducing the phenomenon of smoke and fire from the coke oven.

[0011] 2. This device prevents coke powder from being carried to the coke grid platform by thermal buoyancy, thereby improving the service life of the coke grid rotation mechanism and reducing the risk of short circuits and burnout of electrical equipment caused by coke powder accumulation.

[0012] 3. This device creates a sealed space between the coke grid and the dust collector hood. The sealed space channel makes it difficult for suction to be lost, further guiding the flue gas into the coke dust collector hood to achieve a good dust removal effect.

[0013] 4. This utility model overcomes the environmental factors of high temperature, high impact and frequent operation, and achieves excellent sealing effect in high temperature environment. At the same time, it has the characteristics of strong impact resistance and strong fatigue resistance.

[0014] 5. This utility model has a simple structure, which facilitates the replacement and maintenance of equipment, has a good effect on the control of fugitive emissions, and reduces the cost of dust removal.

[0015] 6. It reduces employees' exposure to harsh coking environments and minimizes their contact time with dust and fumes, effectively improving employee safety and occupational health. Attached Figure Description

[0024] Figures 1 to 4The high-temperature resistant, ductile coke oven tail dust collector sealing device shown includes an adjusting base, which is a high-temperature resistant fire-retardant sleeve 3. The high-temperature resistant fire-retardant sleeve 3 is formed by welding two long plates together, with a cavity in the middle and open ends. Asbestos ceramic fibers 6 are inserted into the cavity from the open ends to form a high-temperature resistant layer. The high-temperature resistant fire-retardant sleeve 3 has two rows of connecting holes along its length. Connecting plates 2 are pressed onto the front of the high-temperature resistant fire-retardant sleeve 3. There are two connecting plates, which are angle steels with an "L" shaped cross-section and the same length as the high-temperature resistant fire-retardant sleeve 3. The two connecting plates 2 are respectively pressed onto both sides of the front of the high-temperature resistant fire-retardant sleeve 3. Several holes are opened on the two connecting plates 2. Corresponding to the connection holes on the high-temperature fire-retardant sleeve, clamping plates 4 are pressed onto both sides of the back of the adjusting base along its length. The clamping plates 4 are flat steel. The high-temperature resistant combined sleeve is clamped and positioned on both sides by the clamping plates and the connecting plates, resulting in better stability. Several connection holes corresponding to the connection holes on the high-temperature fire-retardant sleeve are opened on the clamping plates 4. One side of the two rows of connection holes on the high-temperature fire-retardant sleeve has positioning holes corresponding to the holes on the connecting plates and clamping plates, and the other side has clamping holes corresponding to the holes on the connecting plates and clamping plates. The positioning holes and clamping holes are staggered, making the connection between this sealing device and the dust collector and coke grid more stable.

[0025] In some embodiments, bolts are inserted into both the positioning hole and the clamping hole and are locked by nuts. The bolts are M12 bolts 1 and the nuts are M12 nuts 5.

[0026] like Figure 5 In some embodiments shown, the side of the adjusting base with positioning holes is connected to the dust hood 7 by M12 bolts 1 and then locked by M12 nuts 5. The side of the adjusting base with clamping holes is connected to the coke grid 8 by M12 bolts 1 and then locked by M12 nuts. The dust hood and coke grid are pressed against the clamping plate.

[0027] This sealing encapsulation flexibly seals the gap between the moving parts at the tail of the coke grate and the dust collector hood, effectively improving the sealing performance and achieving a good dust sealing effect. It solves the problem of large-scale, unorganized emission of flue gas from the tail of the coke grate and the dust collector hood during coke discharge from the coke quenching car, improving the efficiency of coke discharge dust removal and environmental remediation, and reducing production costs. This utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
