Description

Technical Field

[0001] This utility model relates to the field of petrochemical industry conversion furnace technology, and in particular to a fully automatic dust removal device for the outer wall of the furnace tubes of a large tubular conversion furnace / cracking furnace. Background Technology

[0002] In industries such as petrochemicals and coal chemicals, fully automated large-scale tubular converters or pyrolysis furnaces serve as core equipment, undertaking key process steps such as raw material pyrolysis and conversion. During operation, the radiant tubes are subjected to high-temperature and high-load conditions for extended periods, making their outer walls highly susceptible to the accumulation of ash, coke, and other impurities. These deposits not only reduce the heat transfer efficiency of the radiant tubes and increase energy consumption but can also lead to localized overheating, accelerate tube aging, and even cause safety accidents such as tube rupture.

[0003] Currently, the fully automatic dust removal devices for the outer walls of large tubular converters / cracking furnace tubes rely on multiple workers working at heights using wire brushes to clean the outer walls of the radiant tubes of large tubular converters or cracking furnaces. This is not only extremely dangerous but also inefficient and impractical. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, when cleaning the outer wall of the radiant tubes of large tubular converters or pyrolysis furnaces, multiple workers are required to work at heights and use wire brushes to clean the dust. This is not only very dangerous, but also inefficient and impractical. The invention proposes a fully automatic dust removal device for the outer wall of the furnace tubes of large tubular converters / pyrolysis furnaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic large-scale tubular converter / cracking furnace tube external wall dust removal device, including a furnace tube, two support blocks are respectively provided on both sides of the furnace tube, a gimbal is installed between the two sets of support blocks, a telescopic wire brush is installed in the two gimbals, a bracket is provided on both sides of the furnace tube, and a lifting wheel set matching the furnace tube is provided in the two brackets.

[0006] Preferably, each of the two supports has a fixing block on its opposite side, and a linear motor is installed at the opposite end of each of the two fixing blocks. The output ends of the two linear motors pass through the two fixing blocks and are fixed to the two supports respectively.

[0007] Preferably, each of the two sets of gimbals has a connecting block fixed at one end facing away from each other, and a support column is fixed at one end of each of the two connecting blocks facing each other. The fixing block is located between the two support columns and is fixed to the two support columns.

[0008] Preferably, the support block has multiple wire rope cable hanging holes.

[0009] Preferably, a connecting plate is fixed on the outer wall of the bracket, and a locking mechanism is installed at one end of the connecting plate.

[0010] Preferably, one end of each of the two connecting blocks is fixed with an outer cover.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, two gimbals are fitted onto the outside of the furnace tube. Two linear motors drive two supports to move in opposite directions, causing two sets of lifting wheels to contact the outer wall of the gimbals. A steel wire rope is attached to the outside via a cable hook, and its movement lifts the entire device. Simultaneously, a telescopic steel wire brush inside the gimbal automatically cleans the outer wall of the furnace tube, eliminating the need for manual cleaning. Furthermore, the linear motors allow the two sets of lifting wheels to be adjusted according to the width of different furnace tubes, and their contact with the furnace tube provides auxiliary limiting, ensuring stable lifting and lowering and enhancing practicality.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, such as Figure 1-3 As shown, this utility model provides a fully automatic dust removal device for the outer wall of the furnace tube of a large tubular converter / cracking furnace, including a furnace tube 2. Two support blocks 3 are provided on both sides of the furnace tube 2. A gimbal 10 is installed between the two sets of support blocks 3. A telescopic wire brush 11 is installed in each of the two gimbals 10. A bracket 8 is provided on both sides of the furnace tube 2. A lifting wheel set 9 matching the furnace tube 2 is provided in each of the two brackets 8.

[0020] The overall effect of Embodiment 1 is that by attaching two gimbals 10 to the outside of the furnace tube 2, the operation of two linear motors 7 drives two supports 8 to move towards each other, so that the two sets of lifting wheel groups 9 are in contact with the outer wall of the gimbals 10. The steel wire rope is hung through the steel wire rope cable hanging hole 14, and the movement of the steel wire rope drives the entire device to rise and fall. At the same time as rising and falling, the operation of the telescopic steel wire brush 11 inside the gimbals 10 can automatically clean the outer wall of the furnace tube 2 without manual cleaning. Moreover, the operation of the linear motors 7 allows the two sets of lifting wheel groups 9 to be adjusted according to the different width dimensions of the furnace tube 2. On the other hand, the contact between the two sets of lifting wheel groups 9 and the furnace tube 2 achieves an auxiliary limiting effect, enabling the device to rise and fall stably, making it more practical.

[0021] Example 2, as Figure 1-3 As shown, each of the two supports 8 has a fixing block 6 on one side facing away from each other. A linear motor 7 is installed on one end of each fixing block 6 facing away from each other. The output ends of the two linear motors 7 pass through the two fixing blocks 6 and are fixed to the two supports 8 respectively. A connecting block 4 is fixed on one end facing away from each of the two gimbals 10. A support column 5 is fixed on one end of each connecting block 4 facing away from each other. The fixing block 6 is located between the two support columns 5 and is fixed to the two support columns 5. Multiple wire rope cable hanging holes 14 are opened in the support block 3. A connecting plate 12 is fixed on the outer wall of the support 8. A locking mechanism 13 is installed on one end of the connecting plate 12. An outer cover 1 is fixed to one end of each of the two connecting blocks 4.

[0022] The overall effect of Embodiment 2 is that, through the operation of the linear motor 7, the two sets of lifting wheel groups 9 can be adjusted according to the width of different furnace tubes 2. Furthermore, because the two sets of lifting wheel groups 9 are in contact with the furnace tubes 2, an auxiliary limiting effect is achieved, enabling the device to lift and lower stably, thus enhancing its practicality. The support column 5 secures the two fixing blocks 6, preventing them from being suspended in mid-air. The wire rope cable hanging hole 14 facilitates the attachment of the support block 3 to an external wire rope lifting device. The locking mechanism 13 locks the lifting wheel group 9 in place.

[0023] Working principle: When using this device, two gimbals 10 are attached to the outside of the furnace tube 2. At this time, the operation of two linear motors 7 drives two supports 8 to move towards each other, so that the two sets of lifting wheels 9 are in contact with the outer wall of the gimbal 10. The steel wire rope is hung through the steel wire rope cable hanging hole 14 and the movement of the external steel wire rope drives the entire device to rise and fall. At the same time, the operation of the telescopic steel wire brush 11 inside the gimbal 10 can automatically clean the outer wall of the furnace tube 2 without manual cleaning. Moreover, the operation of the linear motors 7 allows the two sets of lifting wheels 9 to be adjusted according to the width of different furnace tubes 2. On the other hand, the contact between the two sets of lifting wheels 9 and the furnace tube 2 achieves an auxiliary limiting effect, enabling the device to rise and fall stably, making it more practical.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
