However, there is currently no special device for effectively cleaning the bottom surface of the anode carbon block. In the prior art, after the main cleaning work of the anode carbon block is completed, the anode carbon block is turned over by hoisting or other mechanical means, with the bottom surface facing up, and then the bottom surface of the carbon block is cleaned by manual scraping.

DETAILED DESCRIPTION
[0033] 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.
[0034] The specific embodiment of the anode carbon block cleaning line involved in the utility model is as follows: Figures 1 to 3As shown, the anode carbon block cleaning line includes a roller conveyor line 1, on which a plurality of rollers 2 are 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 7 is conveyed to the roller conveyor line 1 through an external transmission mechanism, and then the carbon block 7 is driven to move forward along the conveying direction of the conveyor line. Corresponding workstations are arranged on both sides of the roller conveyor line 1 to achieve effective cleaning of the surrounding side, top surface, carbon bowl, etc. of the carbon block 7.
[0035] The conveying direction of the roller conveyor line 1 is defined as conveying from the back to the front, with the rear end being the input end and the front end being the output end. A carbon block bottom surface cleaning device is provided at the rear end of the roller conveyor line 1. The carbon block bottom surface cleaning device is used to effectively clean the bottom surface of the carbon block 7, ensure the flatness of the bottom surface of the carbon block 7, and thoroughly clean the attachments.
[0036] Specifically, the carbon block bottom surface cleaning device includes a knife shaft 3 arranged between two adjacent rollers 2 of the roller conveyor line 1, the axis of the knife shaft 3 is parallel to the axis of the roller 2, and the cleaning device also includes two supports 4 arranged at both ends of the knife shaft 3, the knife shaft 3 is rotatably mounted on the two supports 4, specifically, bearing seats 5 are respectively arranged on the two supports 4, the two bearing seats 5 are coaxially arranged, one end of the knife shaft 3 is rotatably assembled with the bearing seat 5 of one of the supports 4, and the other end is rotatably assembled with the bearing seat 5 on the other support 4. The knife shaft 3 is a rod-shaped straight shaft, and a scraper 31 is arranged on the knife shaft 3, and the scraper 31 is a long strip-shaped blade 32 extending horizontally perpendicular to the conveying direction. A reduction motor 6 for driving the knife shaft 3 to rotate is also connected to one of the supports 4, and the rotation direction of the knife shaft 3 is opposite to the conveying direction of the carbon block 7. The top of the rotating outer contour of the scraper 31 is not lower than the upper surface of the roller 2, so as to fit with the bottom surface of the carbon block 7 and reversely scrape the carbon block 7.
[0037] The reduction motor 6 is used to control the reverse rotation of the cutter shaft 3, and the blade 32 on the cutter shaft 3 is driven to swing in the reverse direction. The upper and lower height limits of the cutter shaft 3 ensure that the blade 32 fits the bottom surface of the carbon block 7, so that the blade 32 can effectively scrape the bottom surface of the carbon block 7.
[0038] In order to support the knife shaft 3 and ensure that the scraping length of the blade 32 is not less than the bottom width of the carbon block 7, two supports 4 are respectively located on the outside of the left and right sides of the roller conveyor line 1. The supports 4 are fixed to the ground through the bottom plate 411, and the height of the supports 4 is basically matched with the height of the roller 2 through the support columns.
[0039] As a preferred embodiment, in order to achieve a close fit between the blade 32 and the bottom surface of the carbon block 7 , an elastic floating mechanism is provided between the support 4 and the blade shaft 3 to drive the blade shaft 3 to move upward to make the blade 32 fit and contact the bottom surface of the carbon block 7 .
[0040] Specifically, the support 4 includes a base 41 and a mounting seat 42 movably assembled on the base 41, the bearing seat 5 mentioned above is mounted on the mounting seat 42, the knife shaft 3 mentioned above is rotatably assembled on the mounting seat 42, and the elastic floating mechanism includes a compression spring 44 clamped between the base 41 and the mounting seat 42. As shown in the figure, the base 41 is a columnar structure extending up and down, the bottom of which is connected to the bottom plate 411, and the top is provided with a mounting hole 412 extending up and down, there are two mounting holes 412, which are arranged at intervals in the front and rear directions, and a spring is fixed at the lower end of the mounting seat 42. The axis of the spring cylinder 43 is consistent with the axis of the mounting hole 412. A guide rod 45 is inserted into the spring cylinder 43 for guidance. The bottom of the guide rod 45 extends downward into the mounting hole 412. The upper end of the guide rod 45 is connected to the mounting seat 42. A compression spring 44 is arranged on the outer sleeve of the guide rod 45. The compression spring 44 is clamped between the spring cylinder 43 and the base 41, and applies an upward moving force to the mounting seat 42. In order to achieve an anti-slip design, an anti-slip nut 46 is connected to the lower end of the guide rod 45. The outer diameter of the anti-slip nut 46 is larger than the inner diameter of the mounting hole 412. In the actual working process, the knife shaft 3 is driven by the compression spring 44 and always maintains an upward moving force. When the carbon block 7 is transported to the top of the knife shaft 3, due to the heavy carbon block 7, the bottom surface of the carbon block 7 presses the knife shaft 3 downward, so that the knife shaft 3 can have a pre-pressure to fit the bottom surface of the carbon block 7 upward. When the knife shaft 3 rotates in the opposite direction, the attachments on the bottom surface of the carbon block 7 can be effectively cleaned and the bottom surface of the carbon block 7 can be leveled.
[0041] As a preferred embodiment, in order to achieve continuous scraping, the scrapers 31 mentioned above have more than two, which are evenly spaced around the circumference of the blade shaft 3. Specifically, each of the scrapers 31 includes more than two blades 32, and each blade 32 is evenly spaced along the axial direction of the blade shaft 3. The blades 32 in two adjacent scrapers 31 are relatively staggered along the axial direction of the blade shaft 3. The scraper 31 composed of multiple blades 32 can effectively save the cost of the scraper 31, and can effectively scrape each position in the width direction of the bottom surface of the carbon block 7 through the staggered arrangement, avoiding the existence of dead angles or unscraped positions, and can adaptively replace the corresponding blade 32 according to the actual wear of the blade 32, effectively saving costs.
[0042] In order to install the blade 32, a blade groove 33 extending along the axis parallel to the blade shaft 3 is provided on the blade shaft 3, and each blade 32 of the scraper 31 is arranged and fixed in the blade groove 33 in sequence and fixed by screwing.
[0043] As a preferred embodiment, in order to realize multiple scraping operations on the bottom surface of the carbon block 7, there are more than two carbon block bottom surface cleaning devices, which are arranged at intervals along the conveying direction. Through the arrangement of multiple cleaning devices, the bottom surface of the carbon block 7 can be quickly scraped multiple times during the movement of the carbon block 7, ensuring the thoroughness of the scraping.
[0044] During actual operation, the carbon block 7 enters the roller conveyor line 1, and the bottom surface of the carbon block 7 is conveyed forward by the positive rotation of the roller 2. When the carbon block 7 moves to above the knife shaft 3, the bottom surface of the carbon block 7 presses the knife shaft 3 downward, and the blade 32 on the knife shaft 3 is tightly attached to the bottom surface of the carbon block 7. Then the reduction motor 6 drives the knife shaft 3 to rotate in the opposite direction, so that the bottom surface of the carbon block 7 can be scraped in the opposite direction, thereby realizing the bottom surface cleaning operation of the carbon block 7 without stopping during the movement of the carbon block 7.
[0045] The structure of the embodiment of the anode carbon block bottom surface cleaning device involved in the utility model is consistent with the structure of the carbon block bottom surface cleaning device in the embodiment of the anode carbon block cleaning line mentioned above, and will not be described in detail.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
