Description

Technical Field

[0001] This utility model relates to the field of anode carbon block roasting technology, specifically to a furnace wall cleaning device for an anode carbon block roasting furnace. Background Technology

[0002] During the roasting process of anode carbon blocks, coke, such as asphalt carbonization layer and dust solidification, will inevitably adhere to the furnace walls. This coke not only affects the thermal efficiency of the roasting furnace, but may also have an adverse effect on the quality of the anode carbon blocks.

[0003] According to the public announcement (CN216205395U), a furnace wall cleaning device for an anode carbon block roasting furnace is disclosed. This technology discloses that the device includes a moving component connected to a power source and a cleaning component; the moving component is connected to the cleaning component, driving the cleaning component to move along the roasting furnace; the cleaning component is a pipe connected to the moving component and fitted into the furnace wall; multiple openings are vertically arranged at the outer ends of both sides of the pipe, each opening being connected to a spray component; the pipe is connected to a pneumatic assembly. The advantages of this invention are: it enables automatic cleaning of the anode carbon block roasting furnace, thus preventing filler material from adhering to the furnace wall; it eliminates the need for manual operation during anode carbon block cleaning; and it facilitates recycling after cleaning. However, the aforementioned comparative documents lack the ability to process coke in different states (such as thick solidified coke, thin adhesive coke, and dusty residue). For example, when faced with a hard coke layer formed by high-temperature sintering, simple gas injection is difficult to effectively break it up, thus making it impossible to complete the cleaning of the furnace wall of the roasting furnace. No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

Through the operation of an electric telescopic rod, the lifting plate rises or falls accordingly, causing the nozzle, scraper, and roller brush assembly to move up and down. The coordinated use of the nozzle, scraper, and roller brush assembly achieves a collaborative operation of "gas loosening—scraper breaking—brush cleaning," treating coking in different states in layers, reducing residue, improving cleaning quality, and lowering the possibility of secondary coking adhesion. This effectively solves the problems in the background technology.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1-3A furnace wall cleaning device for an anode carbon block roasting furnace includes a traveling frame 1 mounted on the roasting furnace, two electric telescopic rods 2 for lifting and lowering, symmetrically distributed about the central axis of the traveling frame 1, and two sets of roller brush assemblies 9 for cleaning the furnace wall. The electric telescopic rods 2 are fixed to the bottom of the traveling frame 1, and a lifting plate 3 is fixedly connected to the telescopic end of each electric telescopic rod 2. The roller brush assemblies 9 are located at the bottom of the lifting plate 3, and a U-shaped tube 4 is fixedly connected to the bottom of the lifting plate 3. The U-shaped tube 4 has a U-shaped longitudinal section and a nozzle 5 is fixedly mounted on it. The bottom of the lifting plate 3 is fixedly... A stabilizing frame 6 is fixedly connected to the U-shaped tube 4. A mounting plate 7 is fixedly connected to the stabilizing frame 6. There are two mounting plates 7, which are symmetrically distributed around the central axis of the stabilizing frame 6. A scraper 8 is fixed on the mounting plate 7. The scraper 8 is a serrated hard alloy scraper. A driving component 10 is provided on the lifting plate 3. The driving component 10 enables the roller brush assembly 9 to clean the furnace wall. The electric telescopic rod 2 runs, and the height of the lifting plate 3 changes accordingly. Compressed gas is transmitted to the inner wall of the U-shaped tube 4 and sprayed out through the nozzle 5. The mounting plate 7 drives the scraper 8 to move up and down. The roller brush assembly 9 moves at the same time, realizing the coordinated operation of "gas loosening - scraper 8 breaking - brush cleaning" to treat coking in different states in layers.

[0018] Reference Figure 3-4 The roller brush assembly 9 includes two shafts 91 rotatably connected to the lifting plate 3. Rotating wire brushes 92 are fixedly mounted on the outer walls of the two shafts 91. When the walking frame 1 is placed on the furnace wall, the outer walls of the rotating wire brushes 92 are in close contact with the inner wall of the furnace wall. Limiting plates 93 are fixedly connected to the bottom of the two shafts 91. The limiting plates 93 increase the stability of the rotation of the two shafts 91. The shafts 91 drive the rotating wire brushes 92 to rotate and clean the furnace wall.

[0019] Reference Figure 2-4 The drive assembly 10 includes a motor 101 fixed on the lifting plate 3. The output end of the motor 101 is connected to one of the shafts 91. A large transmission wheel 102 is fixed on one of the shafts 91, and a small transmission wheel 104 is fixed on the other shaft 91. The small transmission wheel 104 is connected to the large transmission wheel 102. After the motor 101 is running, one of the shafts 91 rotates. With the cooperation of the large transmission wheel 102, the belt 103 and the small transmission wheel 104, the two shafts 91 rotate simultaneously, thereby cleaning both sides of the inner wall of the furnace at the same time.

[0020] Reference Figure 2-4The distances between the rotating wire brush 92, the scraper 8, and the nozzle 5 and the stabilizing frame 6 decrease sequentially. The nozzle 5, the scraper 8, and the rotating wire brush 92 clean the coke deposits on the inner wall of the furnace in sequence, reducing the possibility of secondary coke adhesion.

[0021] Reference Figure 4 There are two U-shaped tubes 4, and a connecting pipe 11 is fixedly connected between the two U-shaped tubes 4. The connecting pipe 11 is fixedly connected to the limiting plate 93, and the connecting pipe 11 makes the gas evenly distributed in the two U-shaped tubes 4.

[0022] Reference Figure 1 and Figure 4 A hose 12 is fixedly connected to one of the U-shaped tubes 4. An air compressor 13 is fixedly installed on the walking frame 1. The air outlet of the air compressor 13 is fixedly connected to the hose 12. After the air compressor 13 is running, the compressed gas is transmitted through the hose 12 to one of the U-shaped tubes 4 and sprayed out through the nozzle 5. The model of the air compressor 13 is HF-3 / 7.

[0023] Reference Figure 1 Nozzle 5 adopts a spiral nozzle structure and the spray angle is 30-60°. Nozzle 5 causes high-pressure gas to generate a rotating jet when it passes through, forming a composite flow field of "central high-speed flow + peripheral diffusion flow", which plays a role in loosening coke.

[0024] Working principle: The traveling frame 1 is placed on the roasting furnace and can move along the furnace body to the position to be cleaned. The electric telescopic rod 2 is fixed at the bottom of the traveling frame 1. Its telescopic end drives the lifting plate 3 to achieve vertical lifting and lowering to adapt to the cleaning needs of different heights of the furnace wall. The lifting plate 3 simultaneously drives the scraper 8, the rotating wire brush 92 and the nozzle 5 to move up and down. The air compressor 13 generates compressed gas, which is delivered to the spiral nozzle 5 through the hose 12, the U-shaped pipe 4 and the connecting pipe 11. The nozzle 5 sprays compressed gas onto the furnace wall at a spray angle of 30-60°, initially loosening the wall. During coking, the motor 101 in the drive assembly 10 drives one of the shafts 91 to rotate through its output end. The transmission of the large transmission wheel 102, belt 103 and small transmission wheel 104 causes the two shafts 91 to rotate synchronously. The rotating wire brush 92 installed on the shaft 91 performs fine cleaning on the furnace wall. The distance between the scraper 8, the rotating wire brush 92 and the nozzle 5 and the furnace wall decreases in sequence. First, the nozzle 5 sprays gas to loosen the coke, then the scraper 8 breaks up the harder lumps, and finally the rotating wire brush 92 cleans up the residue, achieving a layered and progressive cleaning.

[0025] This invention utilizes the operation of the electric telescopic rod 2 to raise or lower the lifting plate 3, causing the nozzle 5, scraper 8, and roller brush assembly 9 to move up and down accordingly. Through the coordinated use of the nozzle 5, scraper 8, and roller brush assembly 9, a collaborative operation of "gas loosening - scraper breaking - brush cleaning" is achieved, which can treat coking in different states in layers, reduce residue, improve cleaning quality, and reduce the possibility of secondary adhesion of coking.

[0026] The compressed gas is transmitted through the hose 12 to one of the U-shaped pipes 4 by the operation of the air compressor 13. The compressed gas is circulated through the connecting pipe 11 to ensure the injection pressure and flow rate, thereby enhancing the coking and loosening effect.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
