[0040] In order to make the technical purpose, technical solution and beneficial effects of the utility model clearer, the technical solution of the utility model is further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0041] The specific embodiment of the anode carbon block cleaning line involved in the utility model is as follows: Figures 1 to 3 As shown, the anode carbon block cleaning line includes a roller conveyor line 1, and the roller conveyor line 1 includes a plurality of rollers 11 arranged at intervals along its conveying direction. The structure and working principle of the above-mentioned roller conveyor line 1 are consistent with the prior art and are not described in detail. During the normal cleaning process, the carbon block 5 is driven and conveyed to the roller conveyor line 1, and the carbon block 5 is driven to move horizontally along the conveying direction through the positive rotation of the roller 11.

[0042] The conveying direction of the roller conveyor line 1 is defined as conveying from back to front, with the rear end being the input end and the front end being the output end. A bottom edge cleaning device is provided at the input end of the roller conveyor line 1. The bottom edge cleaning device is mainly used to scrape and clean the bottom edges of both sides of the carbon block 5 through the corresponding scraper 4 when the carbon block 5 is moving, so as to ensure that the attachments on the bottom edges of the carbon block 5 can be effectively cleaned.

[0043] The bottom edge cleaning device includes two cleaning racks 2 arranged between two adjacent rollers 11, and the two cleaning racks 2 are respectively installed on the beams 12 on the left and right sides of the roller 11, and the two cleaning racks 2 are arranged horizontally and symmetrically at intervals perpendicular to the conveying direction. Taking one of the cleaning racks 2 as an example, as shown in the figure, the cleaning rack 2 is connected with a knife rack 3, and the knife rack 3 has a scraper 4 arranged toward the bottom edge of the carbon block 5, the blade section of the scraper 4 is consistent with the bottom edge section of the carbon block 5, the bottom surface height of the scraper 4 is lower than the upper surface height of the roller 11, and the top surface height of the scraper 4 is higher than the upper surface height of the roller 11. An elastic member is connected between the scraper 4 and the knife rack 3 to apply a force to the scraper 4 to move inward to fit on the bottom surface of the carbon block 5; and an anti-slip structure is provided between the scraper 4 and the knife rack 3. In the actual working process, the scrapers 4 on both sides are pushed by the elastic member and are in close contact with the bottom edge of the carbon block 5. As the carbon block 5 is conveyed forward, the scraper 4 can effectively clean the edge attachments of the bottom edge without stopping the machine.

[0046] As a preferred embodiment, the cleaning frame 2 includes an axis plate 21 fixed on the side of the roller conveyor line 1 and a movable plate 22 floatingly assembled on the axis plate 21. The adjustment mechanism is arranged between the axis plate 21 and the movable plate 22 of the left cleaning frame 2, and the tool holder 3 is installed on the movable plate 22. This arrangement can ensure the functional independence of each structure, and each component is individually designed, processed and assembled, thereby reducing the process complexity in the design process.

[0047] Specifically, the shaft plate 21 is provided with a shaft hole 211 extending horizontally perpendicular to the conveying direction, the adjustment structure includes an adjustment shaft 23 inserted in the shaft hole 211, the inner end of the adjustment shaft 23 is fixedly connected to the movable plate 22, and the adjustment mechanism also includes a locking hole 212 provided on the left cleaning frame 2, the axis of the locking hole 212 is perpendicular to the axis of the adjustment shaft 23, and a locking nail is connected to the locking hole 212. In the actual adjustment process, the left and right positions of the adjustment shaft 23 are adjusted to adjust the spacing between the two scrapers 4, and then fixed by the locking nail to ensure the uniformity of the spacing between the two scrapers 4 during the working process.

[0048] As a preferred embodiment, in order to ensure that the direction of the hanging knife will not deviate or swing during adjustment, there are two adjustment shafts 23, which are arranged at intervals on the left cleaning frame 2, and the outer ends of the two adjustment shafts 23 are connected with coupling plates 2421.

[0049] As a preferred embodiment, in order to avoid damage and vibration caused by rigid impact of the scraper 4 on the two cleaning frames 2 during the scraping operation, the movable plate 22 includes a base plate 221 and a mounting plate 222 connected to the inner side of the base plate 221, a buffer pad 223 is installed between the base plate 221 and the mounting plate 222, and the knife holder 3 is fixed on the inner side of the mounting plate 222. The buffer pad 223 can be designed in multiple layers, and the inner and outer layers are stacked.

[0050] In order to install the scraper 4, in this embodiment, the blade holder 3 includes a mounting block 31, the inner surface of the mounting block 31 is provided with a blade groove 311 extending up and down, the scraper 4 is movably mounted in the blade groove 311, and the elastic member is a compression spring mounted between the bottom wall of the blade groove 311 and the scraper 4. Since the scraper 4 is a plate-type blade structure with a blade formed on its inner side, the design of the guide groove can satisfy the floating assembly of the scraper 4 in the left and right directions.

[0051] As a preferred embodiment, in order to realize the installation and anti-slip design of the scraper 4 in the knife groove 311, the above-mentioned knife groove 311 passes through the mounting block 31 up and down, and the upper and lower ends of the mounting block 31 are blocked with blocking plates 32. The anti-slip structure includes relatively extending retaining edges 312 arranged on the groove walls on both sides of the inner groove of the knife groove 311, and the side walls on both sides of the scraper 4 are provided with through grooves extending up and down. The anti-slip structure also includes roller needles 33 inserted in the through grooves. The spacing between the roller needles 33 on both sides is greater than the spacing between the two retaining edges 312 to realize the anti-slip design of the scraper 4 relative to the knife groove 311. There are more than two roller needles 33 on each side, which are arranged side by side in the left and right directions. The roller needles 33 can not only meet the anti-slip design of the scraper 4, but also ensure the smoothness of the left and right movement of the scraper 4 and reduce the sliding friction.

[0052] Furthermore, in order to achieve multiple scraping operations on the bottom surface of the carbon block 5, there are more than two knife grooves 311, which are arranged at intervals along the conveying direction.

[0053] Of course, in other embodiments, adjustment mechanisms may be provided on the cleaning racks 2 on both sides.

[0054] In other embodiments, the scraper 4 can be assembled in a floating manner by assembling the guide rod and the spring 6 tube.

[0055] In other embodiments, the floating direction of the scraper 4 may also extend along an inclined direction perpendicular to the blade.

[0056] The structure of the bottom edge cleaning device in the embodiment of the utility model is consistent with the structure of the bottom edge cleaning device in the embodiment of the carbon block cleaning line mentioned above, and will not be described in detail.
