Description

Technical Field

[0002] Anode carbon blocks are a large-scale auxiliary product necessary for aluminum electrolysis production. During the roasting process, fillers, especially asphalt, adhere to the surface of anode carbon blocks, so the cleaning of attachments to anode carbon blocks after roasting has always been a major problem in the industry. At present, the cleaning of anode carbon blocks and the collection of cleaning waste are mainly done manually, which is inefficient, and the operation level of different employees is uneven, and the cleaning effect is difficult to guarantee, which seriously affects the production efficiency of anode carbon blocks. In addition, due to the large amount of smoke in the cleaning environment, it pollutes the environment and causes harm to the human body.

[0003] The existing methods for removing carbon block surface attachments are as follows:

[0004] 1. Manual cleaning: mainly cleaning the large surface of the anode carbon block, but not the end surface. This method has high labor intensity, low productivity and poor coke cleaning effect.

[0005] 2. Simple scraper cleaning: A set of scrapers are installed on both sides of the anode carbon block conveyor line to scrape the coke on the surface of the anode carbon block. However, this method has a weak scraping force on the coke, and the cleaning effect is poor. It can only scrape the longitudinal sides of the carbon block in the forward direction of transportation, and the coke on the end surface needs to be cleaned manually.

[0006] 3. Cleaning by disc knife. For example, a prebaked anode carbon block cleaning tool is disclosed in the Chinese utility model patent document with authorization announcement number CN217802512U.

[0058] The overall structure of the swivel seat 3 is as follows: Figure 5As shown, it includes a base sleeve 31 and a rotating disk 32 connected to the base sleeve 31. A key block 311 is provided on the inner wall of the base sleeve 31 for cooperating with the spindle 22 to stop rotation. At the same time, a stop hole 312 that passes through the inside and outside is opened on the base sleeve 31 and the key block 311. The base sleeve 31 and the key block 311 are fixedly connected to the spindle 22 by screws passing through the base sleeve 31 and the key block 311, thereby realizing the fixed coaxial assembly of the rotating seat 3 and the spindle 22. When the spindle 22 rotates, the rotating seat 3 rotates synchronously. The rotary disk 32 is provided with three guide holes 321, the axes of the guide holes 321 extend in the front-to-back direction, and the guide holes 321 are evenly spaced around the circumference of the rotary disk 32.

[0059] The overall structure of the cutter head 4 is as follows: Figure 6 As shown, three connecting holes 41 are provided on the cutter disc 4, and the axes of the connecting holes 41 extend in the front-to-back direction. Each connecting hole 41 is coaxially arranged with each guide hole 321 on the rotary disc 32, and each connecting hole 41 is evenly spaced around the circumference of the cutter disc 4. At the same time, the cutter disc 4 also has three mounting platforms 42 extending radially outward from the cutter disc 4. A radially extending knife groove 43 is provided at the front end of the mounting platform 42. The groove wall of each knife groove 43 is inclined in a direction at a set angle to the front-to-back direction, and the scraping head is installed in the knife groove 43.

Through the floating connection, when scraping the surface of the carbon block, the blade disc 4 can adaptively adjust the contact force between the blade disc 4 and the carbon block to avoid the rigid contact between the two and damage to the carbon block or the blade head.

[0062] Specifically, a guide rod 7 is connected between the cutter disc 4 and the swivel seat 3. There are more than three guide rods 7, which are arranged at intervals around the circumference of the swivel seat 3 between the cutter disc 4 and the swivel seat 3.

[0063] As a preferred embodiment, in addition to ensuring the front and rear floating of the cutter disc 4, in order to further adapt the inclination angle of the robot's manipulator 1 relative to the surface of the carbon block, and at the same time to adapt to the inclined side walls of some carbon blocks, in order to ensure that the surface of each carbon block is at any angle, the flat scraping head 5 can be in contact with the surface of the carbon block, the edge of the cutter disc 4 swings back and forth relative to the swivel seat 3. Specifically, a positioning sleeve 44 is inserted into the connection hole 41 on the cutter disc 4, and the inner hole of the positioning sleeve 44 is a ball hole. At the same time, the front limit structure includes a ball sleeve 71 fixed to the front end of the guide rod 7.

[0064] Furthermore, the rear limit structure includes a limit nut 75 screwed on the rear end of the guide rod 7. Specifically, the rear end of the guide rod 7 is inserted into the guide hole 321 and then extends backward, and is relatively screwed with the limit nut 75 to achieve rear limit.

[0065] As a preferred embodiment, the above-mentioned edge scraper head 6 is floatingly assembled in the accommodating groove 322, and the floating direction is along the radial extension direction of the rotary seat 3, and the edge scraper head 6 can swing back and forth on the rotary seat 3.

It can reasonably adapt to different carbon blocks, and realize the adaptive adjustment of the fit between the edge scraper head 6 and the edge and corner position of the carbon block by the floating mode of the edge scraper head 6 under the premise of coarse adjustment of the cleaning unit 2.

[0066] Specifically, a second floating spring 33 is installed between the edge scraping head 6 and the receiving groove 322, and a peripheral limit structure is provided between the edge scraping head 6 and the receiving groove 322 to prevent the edge scraping head 6 from slipping out of the radial direction of the rotary seat 3. The front and rear ends of the receiving groove 322 have limit members to limit the edge scraping head 6. The peripheral limit structure is formed by a retaining edge 323 extending inwardly from the notch of the receiving groove 322. The limit member is formed by a baffle 34 that blocks the front and rear sides of the receiving groove 322.

[0067] As a preferred embodiment, for the above-mentioned cleaning unit 2, a scraping frame 8 is detachably connected to the side wall of the cleaning seat 21, and a scraping brush 81 is connected to the scraping frame 8.

[0068] In actual use, the robot can be roughly divided into three steps. That is, after scraping the surface of the carbon block with the flat scraping head 5, the robot controls the cleaning unit 2 to adjust the angle, and attaches the corner cleaning head to the corner position, and fits it with the corresponding chamfer or chamfer. By controlling the rotation of the rotating seat 3 and translating along the extension direction of the corner of the carbon block, the scraping operation of the corner can be achieved; finally, adjust the angle of the cleaning unit 2, attach the scraping brush 81 to the surface of the carbon block, and scrape the surface and corners of the carbon block.
