Description

Technical Field

[0001] The utility model relates to the field of coking equipment, in particular to a hot maintenance tool for a tamping coke oven with coke on. Background Art

[0002] A coke oven is the most complex furnace in the metallurgical industry. A coke oven is both a thermal equipment with a very complex structure and a large volume, and can also be used as a chemical reactor under high-temperature environment. In the high-temperature coking process, coal is heated in an airtight manner, and after physical and chemical processes such as drying of wet coal, thermal cracking and condensation, and shrinkage of the colloid at high temperature, coke is obtained.

[0003] During the continuous production process, due to operations such as coal charging, furnace door removal, and coke pushing, temperature stress, mechanical pressure, and chemical corrosion are continuously caused, resulting in varying degrees of deformation, cracks, pitted surfaces, and corner breakage in individual parts of the furnace head and furnace wall, causing problems such as furnace wall leakage, black smoke emission from the chimney, and low furnace head temperature, and further resulting in uneven coke maturity and affecting coke quality. Since the temperature inside the coke oven cannot reach the standard within the specified time, the coke maturity is insufficient. When a local part of the coke oven wall is damaged, the traditional maintenance method is to stop production for maintenance. However, stopping production for maintenance not only affects production efficiency but also causes damage to the furnace wall of the non-damaged part due to the overall temperature reduction of the furnace wall.

[0004] Patent CN110982540A discloses a method for hot maintenance of a tamping coke oven with coke on. According to the internal dimensions of the coke oven to be repaired, a coal cake limiting device is made, and then the made coal cake limiting device is installed inside the coke oven. The internal space of the coke oven is divided into a normal coking area and an empty area through the coal cake limiting device, and then coal charging, tamping, and coking are carried out. However, the size of the coal cake limiting device used in this method is small, and it is only applicable to the case where the wall surface is damaged near the side end of the coke oven, and the size of the coal cake limiting device is fixed, so its application range is small.

[0005] Therefore, there is still a great room for improvement in the current hot maintenance device for a tamping coke oven with coke on. Summary of the Utility Model

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] An object of the present utility model is to provide a tamping coke oven hot maintenance tool with coke to repair different damaged positions of the furnace wall. The tamping coke oven hot maintenance tool with coke generally includes a first half, a second half and a telescopic driver. The first half and the second half are nested structures with opposite openings. The first half includes two transverse outer plates and at least one longitudinal outer plate. The two transverse outer plates are opposite and spaced apart. The two ends of the longitudinal outer plate are respectively connected to the first sides of the two transverse outer plates, and the second sides of the two transverse outer plates are open. The second half includes two transverse inner plates and at least one longitudinal inner plate. The two transverse outer plates are sleeved outside the two transverse inner plates. The two ends of the longitudinal inner plate are respectively connected to the second sides of the two transverse inner plates, and the second half can be slidably engaged with the first half. The telescopic driver includes a cylinder body and a telescopic shaft. The cylinder body is installed on the inner wall of the longitudinal outer plate. The telescopic shaft extends from the first side towards the second side and is connected to the longitudinal inner plate at the second side.

[0032] During use, place the tool inside the coke oven. Operate the cylinder body of the telescopic driver according to the damaged position of the furnace wall, so that the telescopic shaft transversely moves the second half to cover the area where the damaged position of the furnace wall is located, forming a vacant area for the repair cavity. Use the cylinder body and the telescopic shaft to maintain the position of the second half. Charge coal into the remaining area of the coke oven and tamp it. After the coal charging and tamping are completed, operate the cylinder body so that the telescopic shaft retracts the second half into the first half. Remove the tamping coke oven hot maintenance tool with coke from the coke oven, and then perform subsequent operations.

[0033] According to the coking oven coke-bearing hot maintenance tool of the present utility model, by providing two movable first halves and second halves, and arranging telescopic drivers in the two halves, the distance between the two longitudinal plates can be changed by using the telescopic drivers according to different furnace wall maintenance positions, so as to realize the repair of furnace wall breakage at different positions and improve the utilization rate of the equipment.

[0034] The following will exemplarily and elaborately describe the coking oven coke-bearing hot maintenance tool according to the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0035] Figure 1 The schematic diagram of the coking oven coke-bearing hot maintenance tool according to an embodiment of the present utility model is shown. Figure 2 The top view of the coking oven coke-bearing hot maintenance tool according to an embodiment of the present utility model is shown.

[0036] As Figure 1-2 shown, the coking oven coke-bearing hot maintenance tool of this embodiment generally includes a first half 100, a second half 200, and a telescopic driver 300.

[0037] The first half 100 includes a housing 110. The housing 110 is provided with baffles on at least three sides and has an open structure on one side. For example, the housing 110 may include two transverse outer plates and one longitudinal outer plate. The two transverse outer plates are opposite and spaced apart. The two ends of the longitudinal outer plate are respectively connected to the first side (the right side in the figure) edges of the two transverse outer plates. The second side (the left side in the figure) of the two transverse outer plates has an open structure without a baffle, so that the second half 200 can be nested into the housing 110. In the present disclosure, the first side and the second side are two relatively laterally separated sides.

[0038] The second half 200 includes a housing 210, which can be nested into the first half 100. The housing 210 is provided with baffles on at least three sides and has an open structure on one side. For example, the housing 210 may include two transverse inner plates and one longitudinal inner plate. The two transverse outer plates are sleeved outside the two transverse inner plates. In other words, the second half 200 is inserted into the first half 100 from the open side (i.e., the second side) of the first half 100, so that the two are nested together. The two ends of the longitudinal inner plate of the second half 200 are respectively connected to the second side (the left side in the figure) edges of the two transverse inner plates. The first side (the right side in the figure) of the second half 200 has an open structure without a baffle, so as to be connected to the telescopic driver 300.

[0039] The second half 200 and the first half 100 can be slidably engaged, so that the two can move laterally relative to each other under the operation of the telescopic driver 300, and at the same time can provide auxiliary support for each other.

[0040] In some embodiments, asFigure 1 As shown, a guiding groove 120 is provided on each transverse outer plate, and a guiding pin 220 is provided on the transverse inner plate. The main body of the guiding pin 220 passes through the guiding groove 120, and the head of the guiding pin 220 protrudes outside the guiding groove 120. The width of the head (in the up-down direction in the figure) is larger than the width of the guiding groove 120 (in the up-down direction in the figure), thereby forming a limit to prevent the guiding pin 220 from disengaging from the guiding groove 120. The guiding groove 120 can be a long strip-shaped groove that extends transversely. By providing the guiding groove and the guiding pin, the path of the transverse movement of the second half part 200 relative to the first half part 100 can be restricted, its swaying can be suppressed, and the furnace wall can be prevented from being knocked.

[0041] In some embodiments, a plurality of guiding grooves 120 can be provided on each transverse outer plate, and a plurality of guiding pins 220 can be provided on the transverse inner plate. By providing multiple groups of guiding grooves and guiding pins, the structural stability of the tool can be improved, and when coal charging and ramming are performed, auxiliary support can also be provided for the second half part 200.

[0042] The telescopic driver 300 can include a cylinder body and a telescopic shaft. The cylinder body is fixedly installed on the inner wall of the longitudinal outer plate. The telescopic shaft extends from the first side towards the second side and is fixedly connected to the longitudinal inner plate at the second side. The telescopic shaft changes its transverse length under the action of the cylinder body so as to drive the second half part 200 to move transversely relative to the first half part 100.

[0043] In some embodiments, the housing 110 of the first half part 100 further includes an outer bottom plate, and the outer bottom plate is connected to the bottoms of the two transverse outer plates and the longitudinal outer plate. Correspondingly, the housing 210 of the second half part 200 can further include an inner bottom plate, and the inner bottom plate is connected to the bottoms of the two transverse inner plates and the longitudinal inner plate. The inner bottom plate is positioned above the outer bottom plate. By providing the outer bottom plate and the inner bottom plate, the supporting effect of the first half part 100 on the second half part 200 in the height direction can be enhanced.

[0044] In some embodiments, as Figure 2 shown, a guiding groove 230 is provided on the inner bottom plate, and a guiding pin 130 is provided on the outer bottom plate. The guiding pin 130 is inserted into the guiding groove 230. A plurality of guiding grooves 230 can be provided on the inner bottom plate, and a plurality of guiding pins 130 can be provided on the outer bottom plate to enhance the structural stability.

[0045] In some embodiments, as Figure 1 shown, rollers 140 can be provided below the outer bottom plate. Since the main body structure of this tool is made of relatively thick steel plates, the overall tool is relatively heavy. The rollers 140 are provided to facilitate the movement of this tool.

[0046] In some embodiments, a towing handle 150 is further provided on the outer surface of the longitudinal outer plate of the housing 110. The towing handle 150 is provided to facilitate grasping the tool, thereby facilitating the movement of the tool.

[0047] In some embodiments, the cylinder of the telescopic drive 300 may adopt a hydraulic cylinder. The hydraulic cylinder can provide a large force within a relatively small volume, and its movement is very smooth. The characteristics of the fluid make the movement of the hydraulic cylinder components smoother, reducing impact and vibration. Moreover, the hydraulic cylinder can be operated through a remote control or an automatic control system, facilitating remote operation and automated production, and improving production efficiency and flexibility. The hydraulic cylinder can be installed at the central part of the longitudinal outer plate, making the second half 200 more stable when bearing force during coal charging and ramming, less likely to tilt or shift, and improving the stability and reliability of the entire system.

[0048] During use, place the tool inside the coke oven. Operate the cylinder of the telescopic drive 300 according to the damaged position of the furnace wall, so that the telescopic shaft transversely moves the second half 200 to cover the area where the damaged position of the furnace wall is located, reserving the required space for maintenance. Use the cylinder and the telescopic shaft to maintain the position of the second half 200, charge coal into the remaining area of the coke oven and ram it. After the coal charging and ramming are completed, operate the cylinder so that the telescopic shaft retracts the second half 200 into the first half 100. Remove the hot repair tool for ramming coke oven with coke from the coke oven, and then close the furnace door for coking production. After the coking time reaches the set time, open the furnace door, and then place a fire baffle inside the coke oven. Divide the internal space of the coke oven into a coking area and a maintenance area through the fire baffle. The maintenance area mainly includes the area where the hot repair tool for ramming coke oven with coke was previously placed, which covers the damaged position of the furnace wall that needs to be repaired in the coke oven, and the coking area is the normal coking area filled with coal. After placing the fire baffle, turn off the heating in the maintenance area, and when the temperature in the maintenance area drops to a suitable temperature for maintenance operations, perform maintenance operations on the damaged part of the furnace wall.

[0049] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0050] In addition, it should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0051] Furthermore, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
