Description

Technical Field

[0001] The utility model relates to the technical field of aluminum smelting, in particular to a coking cleaning device for a flue wall of an anode baking furnace. Background Art

[0002] Anode baking furnace is one of the key equipment for producing prebaked anodes for aluminum. The operation condition of the baking furnace will directly affect the product quality and energy consumption of prebaked anodes. After the raw anodes are loaded into the furnace charge box, fillers need to be filled around to separate the direct contact between the anodes and the flue wall, and to isolate the air, fix the shape, and act as a heat transfer medium. During the anode baking process, coking often occurs on the surface of the flue wall. Coking will affect the heat transfer efficiency in the furnace and the normal escape and combustion of volatiles, resulting in increased energy consumption and even affecting product quality.

[0003] In order to ensure the normal operation of the roasting furnace, the coke on the flue wall must be cleaned regularly before loading the furnace to ensure the production of pre-baked anodes with high quality and low energy consumption.

[0004] The common existing coke cleaning equipment includes manually entering the roasting furnace material box with a steel chisel, a hammer, or a flat shovel to pry, hammer, and scrape the coke. However, there are problems such as low cleaning efficiency, poor working environment, high labor intensity for workers, and high safety risks.

[0005] The existing manual cleaning method is: first take out the filler and anode after baking and cooling in the baking furnace, and after the temperature in the baking furnace is lowered, the worker directly enters the baking furnace to clean the solidified materials on the wall of the fire channel. Since the temperature in the baking furnace drops very slowly and the cooling time is also long, on the other hand, these cokes are very firmly bonded, and the cleaned cokes will raise a lot of dust. During the cleaning process, the workers work in an extremely poor working environment, the labor intensity is also very high, the cleaning efficiency is particularly low, it takes a long time to clean up, and the cleaning effect is not ideal. Utility Model Content

[0006] The utility model aims to provide a coking cleaning device for the flue wall of an anode baking furnace, so as to improve the working environment of operators and reduce labor intensity.

[0007] The technical solution of the utility model is: a coking cleaning device for the flue wall of an anode baking furnace, comprising a workbench, a plurality of steel wire ropes arranged at intervals along the length direction X of the workbench, and a pressing plate pressed on the upper ends of the steel wire ropes, both ends of the steel wire ropes extending along the width direction Y of the workbench, both ends of the steel wire ropes in the extending direction are provided with brush heads, the brush heads are placed on the outer side of the workbench, and the workbench is provided with lifting ears.

[0008] Preferably, at least two pressing plates are spaced apart in the width direction Y of the workbench.

[0009] Preferably, the pressing plate is connected to the workbench by bolts, and the bolts and the wire rope are staggered.

[0010] Preferably, the lifting ear comprises a hanging plate and a hanging hole, the bottom of the hanging plate is connected to the workbench, the top of the hanging plate is provided with an arc, and the hanging hole is arranged on the hanging plate.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0018] like Figure 1-Figure 2 As shown, a coke cleaning device for the flue wall of an anode baking furnace provided in this embodiment includes a workbench 1, a brush head 2, a pressing plate 3, a lifting lug 4, a steel wire rope 5 and a bolt 6.

[0019] The workbench 1 is a long rectangular iron plate having a length direction X and a width direction Y. The workbench 1 can increase the counterweight and working area of ​​the device and assemble other accessories. The length of the steel wire rope 5 is longer than the width of the workbench 1. A plurality of steel wire ropes 5 are arranged on the workbench 1 at intervals along the length direction X. The steel wire rope 5 extends to the outside of the workbench 1 along the width direction Y, and the portion extending to the outside forms the brush head 2. The plurality of steel wire ropes 5 can be replaced individually. In addition, the multi-strand rope body at the end of the steel wire rope 5 can be unfolded to form an exploded structure of the brush head 2, thereby increasing the flexibility of the brush head 2 and increasing the contact area between the brush head 2 and the fire channel wall.

[0020] The upper end of the steel wire rope 5 is pressed with the pressing plate 3. At least two pressing plates 3 are arranged at intervals in the width direction Y of the workbench 1. The pressing plate 3 is connected to the workbench 1 by bolts 6, and the bolts 6 and the steel wire rope 5 are staggered.

[0021] The workbench 1 is provided with a lifting lug 4. The lifting lug 4 includes a hanging plate 41 and a lifting hole 42. The bottom of the hanging plate 41 is connected to the workbench 1. The top of the hanging plate 41 is provided with a circular arc. The lifting hole 42 is provided on the hanging plate 41. The lifting hole 42 is a waist-shaped hole extending along the height direction Z. There are four lifting lugs 4, which are respectively provided at both ends of the length direction X of the workbench 1, and two lifting lugs 4 are provided at intervals along the width direction Y on the same end of the length direction X. The lifting lug 4 can be connected to the steel wire rope of the overhead crane and cooperate with the lifting of the overhead crane balance device.

[0022] During cleaning, the hook of the overhead crane is hung in the hanging hole 42 of the lifting ear 4, the overhead crane is started, and the coke cleaning device for the flue wall of the anode roasting furnace is extended into the flue wall. The operator controls the overhead crane up and down on the furnace surface without entering the roasting furnace. Specifically, the cleaning device is first dropped above the roasting furnace material box and flush with the flue wall. Then the overhead crane is controlled to reciprocate up and down, thereby controlling the brush head 2 on the wire rope 5 to reciprocate up and down to clean the coke on the flue wall. Because the brush head 2 is flexible, the brush head 2 can adapt to different wall surfaces, and then the flue wall is cleaned through the adhesion between the brush head 2 and the wall surface. After cleaning, the overhead crane is controlled to lift the cleaning device out of the flue wall.

[0023] The anode baking furnace flue wall coking cleaning device provided by the utility model can smoothly enter the flue wall or move out from the flue wall with the help of an overhead crane, and can be flexibly used according to cleaning requirements.
