Description

Technical Field

[0001] This invention relates to the field of internal hole cleaning technology, specifically to a device for cleaning the holes in prebaked anode carbon bowls. Background Technology

[0002] After forming, the green anode blanks need to be roasted in a roasting furnace before they can be used in electrolytic aluminum production. To prevent deformation and oxidation of the green anode (a semi-finished product, an unroasted prebaked anode; a roasted anode is a prebaked anode that has been roasted) carbon blocks during roasting, granular materials are needed to fill around the anode and inside the anode carbon bowl for protection. These materials are called fillers. The fillers are roasted along with the green anode, and they adhere to the surface of the anode and the bowl holes, making subsequent cleaning quite troublesome. If the anode is damaged during cleaning, it will increase the production cost of the anode.

[0003] Cleaning the outer surface of the calcined anode is relatively simple. For example, a device for cleaning the surface filler of the calcined anode carbon block after baking is disclosed in patent number 202122435017.8, which describes the use of a grinding disc to clean the anode surface. However, cleaning the bowl hole area is very difficult. The current cleaning method is simple manual cleaning, which has low cleaning efficiency and many variable factors in the cleaning process (such as the need to manually flip and adjust the position of the calcined anode). There are great drawbacks to cleaning the bowl hole of the calcined anode. Therefore, this invention provides a prebaked anode carbon bowl hole cleaning device. Summary of the Invention

[0019] (III) Beneficial Effects

[0020] This invention provides a device for cleaning the holes in prebaked anode carbon bowls. It has the following beneficial effects:

[0021] 1. This invention uses a roller conveyor line to transport calcined anodes. A cleaning mechanism that moves vertically along the conveyor line is used to drive the cleaning mechanism into and out of the prebaked anode carbon bowl holes, cleaning the inner wall of the bowl holes. Compared with existing manual cleaning, it has the advantages of low labor costs and high cleaning efficiency. The cleaning mechanism is further improved by adopting a set of friction transmission structures, namely a lower transmission disc and an upper transmission disc, which rely on friction to drive the cleaning mechanism to rotate (powered by a geared motor). This allows the cleaning mechanism to remain stationary while moving up and down, and to rotate when it reaches a suitable position (when the bottom of the cleaning mechanism is against the sinking opening, i.e., when the cleaning mechanism is fully inserted into the prebaked anode carbon bowl hole), cleaning the inner wall of the prebaked anode carbon bowl hole, achieving a better cleaning effect (the cleaned thickness is uniform and consistent).

[0022] 2. This invention employs several sets of equidistantly distributed cleaning rings, with a pressure ring positioned above them. The appropriate number of cleaning rings and pressure rings of different lengths can be selected as needed, making it suitable for products with different depths of prebaked anode carbon bowl holes, thus greatly increasing its applicability.

[0023] 3. The present invention, by setting a guide structure composed of a guide post and a guide seat, can ensure the smooth sliding of the bottom cleaning mechanism. The spring set on the guide post can provide the cleaning mechanism with an elastic thrust, avoiding the resistance generated by the cleaning hair and the inner wall of the prebaked anode carbon bowl hole, which would affect the cooperation between the lower transmission plate and the upper transmission plate.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] like Figure 1-9 As shown, this embodiment of the invention provides a prebaked anode carbon bowl hole cleaning device, including: a roller conveyor line 1 and a gantry frame 6 located outside the roller conveyor line 1. The gantry frame 6 mainly serves as an installation and support; specifically, the gantry frame 6 includes two symmetrically distributed frames. The bottom of the frame is provided with mounting feet, which are fixed to the ground with screws to ensure its stability. The inner side of the frame is provided with a sliding opening. The side of the mounting plate 7 is located inside the sliding opening, and a fastening screw is provided between the mounting plate 7 and the sliding opening. The fastening screw is threaded from above the sliding opening and its bottom end is pressed against the mounting plate 7.

[0037] The roller conveyor line 1 has a carrier plate 3 in the middle, that is, the two ends of the carrier plate 3 are fixedly connected to the side frame of the roller conveyor line 1, and its length direction is along the axial direction of the roller. The carrier plate 3 has a recessed opening 4. A cleaning component that can be raised and lowered is installed on the top of the gantry frame 6 and directly above the recessed opening 4.

[0038] Cleaning the bowl holes and surface of the calcined anode is a conventional choice. Existing cleaning structures, such as brush cleaning discs and cleaning rollers, are set on roller conveyor line 1. The surface cleaning of the calcined anode can be used in conjunction with this device, which saves more labor costs.

[0039] The lifting cleaning component moves up and down to clean the bowl-shaped parts of the prebaked anode carbon passing through the roller conveyor line 1.

[0040] Reference Appendix Figure 3 The lifting cleaning component includes a mounting plate 7, a mounting base 8 is provided inside the center hole of the mounting plate 7, a telescopic cylinder 9 is fixedly connected to the bottom of the mounting plate 7, and the top telescopic end of the telescopic cylinder 9 is fixedly connected to the mounting base 8.

[0041] The telescopic cylinder 9 is used to extend and retract, which drives the mounting base 8 to move up and down, thereby driving the cleaning structure connected to the mounting base 8 to move up and down.

[0042] Reference Appendix Figure 5 , Figure 6 A geared motor 10 is fixedly connected to the top of the mounting base 8, and an upper transmission disk 12 is fixedly connected to the bottom of the geared motor 10. That is, the geared motor 10 directly drives the upper transmission disk 12 to rotate. A cleaning mechanism is slidably connected to the bottom of the mounting base 8. The cleaning mechanism can slide up and down with the mounting base 8. The top of the cleaning mechanism has a lower transmission disk 20. The bottom of the lower transmission disk 20 and the top of the upper transmission disk 12 transmit rotation through friction.

[0043] When the cleaning mechanism moves to the bottom, its bottom end abuts against the recess 4. When the mounting base 8 continues to move down, the upper transmission plate 12 and the lower transmission plate 20 will squeeze each other to achieve the transmission of rotation. At this time, the cleaning mechanism rotates to clean the inner wall of the prebaked anode carbon bowl hole.

[0044] Reference Appendix Figure 1 In this embodiment, a liftable positioning stop 2 is provided on the roller conveyor line 1 and on the side where the carrier plate 3 is discharged. The liftable positioning stop 2 is located between two adjacent rollers of the roller conveyor line 1.

[0045] The liftable positioning stop 2 specifically includes two sets of lifters and a blocking plate. The lifters drive the blocking plate to move up and down. When the liftable positioning stop 2 is raised, it can prevent the prebaked anode from being conveyed on the roller conveyor line 1. At this time, the prebaked anode carbon bowl hole corresponds to the sinking port 4, ensuring that it is located directly below the cleaning mechanism.

[0046] Reference Appendix Figures 7-9 In this embodiment, the cleaning mechanism includes a cleaning shaft 13, with an end block 14 fixedly connected to the bottom end of the cleaning shaft 13. A cleaning ring 15 and a pressure ring 16 are slidably connected to the outer side of the cleaning shaft 13 along the axial direction. The end block 14 restricts the cleaning ring 15 from sliding out from the lower end, and the bottom end of the end block 14 can correspond to the recessed opening 4 and press against the inner bottom of the recessed opening 4. The pressure ring 16 is located above the cleaning ring 15. The lower transmission disk 20 is located at the top of the cleaning shaft 13. That is, the upper transmission disk 12 and the lower transmission disk 20 structure drive the cleaning shaft 13 to rotate, thereby driving the cleaning ring 15 to rotate and clean the inner hole.

[0047] Reference Appendix Figure 9In this embodiment, a neck 19, i.e. a small diameter section, is provided near the top of the cleaning shaft 13. A clamp 21 is installed on the outside of the neck 19, and a guide seat 23 is provided on the side of the clamp 21. A guide post 22 is fixedly connected to the bottom of the mounting base 8. The guide post 22 is slidably connected to the guide seat 23, and the bottom end of the guide post 22 has a limiting connection end. A spring 24 is sleeved on the guide post 22. The limiting connection end can restrict the separation of the guide seat 23 and the guide post 22, i.e., it will not fall.

[0048] A spline block 18 is provided on the inner side of the cleaning ring 15, and a spline opening 17 is provided on the outer side of the cleaning shaft 13. The spline block 18 corresponds to the spline opening 17 to realize the rotational transmission between the cleaning shaft 13 and the cleaning ring 15. Several sets of cleaning bristles are provided on the outer side of the cleaning ring 15 along the radial direction of the cleaning ring 15. During the rotation of the cleaning bristles, they extend outward to clean the inner wall of the bowl hole.

[0049] Multiple cleaning rings 15 are provided and distributed along the axial direction of the cleaning shaft 13. The number of cleaning rings 15 can be selected according to different needs to adapt to the cleaning of bowl holes of different depths.

[0050] Reference Appendix Figure 1 In this embodiment, a boss is provided at the center of the inner bottom of the recessed opening 4, and a follower plate 5 is provided on the inner side of the recessed opening 4. The middle part of the follower plate 5 protrudes upward, and the bottom of the protrusion corresponds to the boss of the recessed opening 4. The bottom of the cleaning shaft 13 pushes against the follower plate 5, so that the lower transmission disk 20 above and the upper transmission disk 12 are driven. At this time, the cleaning shaft 13 itself will also rotate, and the follower plate 5 will rotate together with the cleaning shaft 13, which can reduce the friction between them.

[0051] The top of the lower transmission disc 20 is provided with a first friction surface, and the bottom of the upper transmission disc 12 is provided with a second friction surface. The first friction surface and the second friction surface correspond to each other. The friction coefficient of the friction surfaces is relatively large, so the transmission torque transmitted between them will be large.

[0052] Working principle: The baked anode is placed on the roller conveyor line 1. As it is conveyed by the roller, when one end of it hits the liftable positioning stop, it stops being conveyed by the roller. At this time, the prebaked anode carbon bowl hole is aligned with the sinking opening 4. The telescopic cylinder 9 controls the mounting seat 8 to move downward, that is, the cleaning shaft 13 is inserted downward into the bowl hole. When the end block 14 at the bottom of the cleaning shaft 13 hits the follower plate 5, the cleaning shaft 13 stops moving downward. The mounting seat 8 and the cleaning shaft 13 are slidably connected. As it continues to move downward, the guide column 22 and the guide seat 23 slide relative to each other and compress the spring 24. When the friction generated by the compression between the lower transmission plate 20 and the upper transmission plate 12 is large enough, the rotation of the reduction motor 10 (which is always working) is transmitted to the cleaning shaft 13, which drives the cleaning ring 15 to rotate and clean the prebaked anode carbon bowl hole.

[0053] After cleaning is completed, the telescopic cylinder 9 returns to its original position, causing the entire cleaning structure to move upward and away from the prebaked anode carbon bowl hole. The liftable positioning stop 2 then falls back down, and the cooked anode continues to be conveyed with the roller. The device waits for the next cooked anode to be cleaned, and this process is repeated to achieve efficient and automated cleaning.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
