[0072] The housing 36 is a hollow structure that can be detachably connected to the charcoal bowl to be cleaned.

[0077] In a preferred embodiment of the prebaked anode disassembly, cleaning and online weighing system, the scraper 37 is connected to the flange via hexagon socket bolts and abuts against the bottom of the carbon bowl. The scraper 37 has a plurality of scraping teeth.

[0079] In a preferred embodiment of the above-mentioned system for disassembling, cleaning and online weighing of prebaked anodes, a block pushing trolley 17 for conveying the prebaked anodes 2 to the warehouse is provided on the qualified block conveying track.

[0080] In one embodiment, the scraper 37 is connected to the flange by an internal hexagonal bolt and the scraper 37 abuts the bottom of the charcoal bowl. The radius of the scraper 37 is the same as the radius of the shell 36 and there is a gap between the top of the scraper 37 and the bottom of the shell 36.

The second flange is connected to the top of the driving device 34 via an internal hexagonal bolt, and the first flange is connected to the bottom end of the vibration cylinder 32 via an internal hexagonal bolt. The dust collection device includes a vacuum pump.

[0081] In one embodiment, a disassembly and cleaning device is installed after the prebaked anodes 2 are baked out of the furnace. The disassembly and cleaning device is equipped with several functions, including receiving the prebaked anodes 2 after they are placed vertically out of the furnace, converting the prebaked anodes 2 to be tilted vertically, conveying, a cleaning platform 12, and a mechanical bidirectional rotating roller conveyor. A rotating motor 24, a reducer, a rotating gear 25, and a conveyor are mounted on the mechanical bidirectional rotating track 16. The device can rotate 90 degrees to the left and right, rotating the cleaned qualified and unqualified prebaked anodes 2 to an output device for transport to the qualified and unqualified block conveyor rollers 19 and 20, respectively. A weighing sensor 22 is installed between the bottom support frame 21 and the weighing connection frame 23. When no prebaked anodes 2 are present, the entire portion above the weighing sensor 22 acts as a weighing plate. When the prebaked anodes 2 enter the conveyor mechanism, gravity presses against the weighing sensor 22, and the weighing sensor 22 begins weighing. After real-time weighing is completed, the inspectors can determine whether the pre-baked anode 2 is qualified or unqualified, and the pre-baked anode 2 can be transported to the qualified block conveyor roller 19 and the unqualified block conveyor roller 20 respectively through the mechanical bidirectional rotating track 16, which rotates 90 degrees left and right, to achieve sorting. Laser height measuring devices are installed on both sides of the conveyor roller directly between the cleaning platform 12 and the sorting rotating mechanism. The sensor transmits the weighing data to the host computer through the PLC, and the height measuring device transmits the height data measured by the height measuring device to the host computer. The length and width of the pre-baked anode 2 are constants, and the height is a variable. The host computer calculates the volume density of the pre-baked anode 2.

[0082] In one embodiment, after the prebaked anode 2 is removed from the furnace, it is placed into the vertical prebaked anode receiving frame 1 using a multifunctional overhead crane. Once placed, the prebaked anode 2 becomes a carbon block to be disassembled. To disassemble the prebaked anode 2, the carbon block is pushed by the first pusher cylinder 3 into the vertical tilting mechanism 4. The vertical tilting mechanism 4 tilts and tilts 90°, flipping the prebaked anode 2 from a vertical position to a horizontal position. After the prebaked anode 2 is tilted by the vertical tilting mechanism 4, the post-tilt carbon block pusher cylinder 5 pushes the prebaked anode 2 to the center of the tilting mechanism. Once the prebaked anode 2 reaches the center of the tilting mechanism, the second pusher cylinder 6 pushes the prebaked anode 2 into the drum-type bidirectional flipping mechanism 7. After the prebaked anode 2 is flipped 90°, it returns to its normal position with the carbon bowl facing upward. Through this continuous operation, the prebaked anode 2 that has entered the drum-type bidirectional flipping mechanism 7 and is then pushed into its normal position by the next anode. The thrust of the next prebaked anode 2 pushes the properly tilted prebaked anode 2 out of the drum-type bidirectional flipping mechanism 7. The prebaked anode 2 is pushed into the carbon bowl cleaning machine 10 by a conveyor and the third and fourth pusher cylinders 8 and 9. The carbon bowl cleaning machine 10 comprises a tilting mechanism and a cleaning mechanism, which clean the filling material from the carbon bowl of the prebaked anode 2. Once the carbon bowl is clean, the prebaked anode 2 is flipped back to its normal position and placed on the cleaning platform 12. The cleaning platform 12 has two cleaning stations. The prebaked anode 2 can move straight into one station. To move to the next station, the fifth pusher cylinder 11 is activated to push the prebaked anode 2 to the other station. When the cleaned prebaked anode 2 is transported to the next stage, it passes through a laser height measurement device 13. As the prebaked anode 2 passes, the laser height measurement device 13 measures the height of the prebaked anode 2, and the data is transmitted to a computer. After the height measurement, the prebaked anode 2 stops and waits when it reaches a stopper 14. This stopper 14 is interlocked with a mechanical bidirectional rotating track 16, which can rotate 90 degrees left and right, for example, and a weighing device. When the prebaked anode 2 is working on the mechanical bidirectional rotating track 16, the prebaked anode 2 at the limiter 14 stops running under the action of the limiter 14. When the carbon blocks of the prebaked anode 2 on the mechanical bidirectional rotating track 16 are transported and docked with the conveyor roller behind the cleaning platform 12, the prebaked anode 2 can be transported to the mechanical bidirectional rotating track 16 and the weighing device. Furthermore, the mechanical bidirectional rotating track 16 is provided with a sixth block pushing cylinder 15.

[0083] In one embodiment, the mechanical bidirectional rotating track 16 and weighing device include a bottom support frame 21, on which a weighing sensor 22 is mounted. The upper portion of the weighing sensor 22 can be used as an independent weighing tray; the upper portion has a weighing connection frame 23 connected to the weighing sensor 22, on which are mounted a rotating motor 24 and a combination of a reducer and a pinion, a rotating gear 25, a gear connecting shaft 26, an upper running track 27, running wheels 28 (four in total), a roller bearing 29 and a motor and reducer combination, a roller railing 30, and a carbon block position limiter 31, which can be a mechanical limiter. When the prebaked anode 2 enters the mechanical bidirectional rotating track 16, the roller seat bearing 29 and the motor and reducer combination run to move the prebaked anode 2 forward. The roller railing 30 prevents the prebaked anode 2 from deviating from the roller. The roller length meets the production block requirements. When the small side of the prebaked anode 2 contacts the carbon block in place limit 31, it proves that the prebaked anode 2 has completely entered the roller. At this time, the prebaked anode 2 starts to be weighed and the weighing data is transmitted to the computer. After weighing is completed, the qualified blocks automatically rotate according to the program settings and enter the direction of the qualified block conveyor roller 19. At this time, the rotating motor 24, the reducer and the pinion combination drive the rotating gear 25 to rotate. The rotating gear 25 is connected to the gear connecting shaft 26, the gear connecting shaft 26 and the upper walking track 27. Through the rotation of the rotating gear 25, the upper walking track 27 rotates along the walking wheel 28. When the mechanical two-way rotating track 16 rotated 90 degrees docks with the qualified block conveyor roller 19, the limit control here stops, and the qualified prebaked anodes 2 are transported to the qualified block conveyor track through the conveyor roller. Under the push of the block pusher 17, the qualified prebaked anodes 2 can be transported to each span of the prebaked anode 2 finished product warehouse on the qualified block conveyor track. On the contrary, when the qualified blocks are inspected, the inspector manually operates the mechanical two-way rotating track 16 to transport them to the unqualified block conveyor roller 20. The data of the prebaked anode 2 measured by laser height and weighed is transmitted to the computer. The length and width of the prebaked anode 2 are constants and the height is a variable. The volume density of the prebaked anode 2 is calculated by the program on the host computer. The volume density of the prebaked anode 2 is recorded in the new test and data production.

[0084] The method for disassembling, cleaning and online weighing system of prebaked anodes comprises the following steps:

[0085] The prebaked anodes 2 are arranged in a vertical array of prebaked anodes 2 in a vertical prebaked anode receiving frame 1. The vertical prebaked anodes 2 are pushed by a first push block cylinder 3 and sequentially enter a vertical tilting mechanism 4 from the vertical prebaked anode receiving frame 1 to be flipped 90° to form a flat-lying prebaked anode 2. The flat-lying prebaked anodes 2 are then pushed by a second push block cylinder 6 and sequentially enter a drum-type bidirectional flipping mechanism 7 to be flipped 90° to form a prebaked anode 2 with the carbon bowl facing upward.

[0086] The prebaked anodes 2 enter the carbon bowl cleaning machine 10 in sequence to clean the carbon bowls and are conveyed towards the mechanical bidirectional rotating track 16 in sequence. During the conveying process, the laser altimetry device 13 measures the height of the prebaked anodes 2.

[0087] The weighing sensor 22 measures the weight data of the prebaked anodes 2 on the mechanical bidirectional rotating track 16. When the weight data and the height data are within a predetermined range, the mechanical bidirectional rotating track 16 switches to connect to the qualified block conveying track to input the prebaked anodes 2 into the qualified block conveying track. When the weight data or the height data is outside the predetermined range, the mechanical bidirectional rotating track 16 switches to connect to the unqualified block conveying track to input the prebaked anodes 2 into the unqualified block conveying track.

[0088] Finally, it should be noted that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope protected by the present application.

Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
