[0037] To enable those skilled in the art to better understand the technical solutions in this application, the following will describe in detail the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. The described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.
[0038] As Figure 1 and Figure 2 shown, a pre-baked anode carbon bowl cleaning device includes a cleaning component 1 and a driving component 2 for driving the cleaning component 1 to rotate.
[0039] The cleaning component 1 includes a tool holder 11. The tool holder 11 includes a tool shank 111. One end of the tool shank 111 is fixedly connected to the power output end of the driving component 2 in a detachable manner, and the tool shank 111 can rotate around its own axis under the drive of the driving component 2. A tool rest 112 is fixedly provided at the end of the tool shank 111 away from the driving component 2. A tool 12 extending radially is slidably provided on the tool rest 112. The tool 12 can slide radially relative to the tool rest 112, and the cutting edge of the tool 12 faces outward (with the side close to the tool shank 111 along the radial direction as the inner side). A first spring 13 is provided between the tool rest 112 and the tool 12. In the static state, the tool 12 is in a retracted state under the elastic tension of the first spring 13. When the cleaning component 1 rotates under the drive of the driving component 2, the tool 12 can overcome the elastic tension of the first spring 13 and move outward under the action of centrifugal force, and abut against the side wall of the carbon bowl 42, so as to clean the metallurgical coke particles adhering to the inside of the carbon bowl 42.
[0040] The driving component 2 can adopt a motor, a rotary cylinder or a pneumatic wrench. As a specific implementation manner, in this embodiment, the driving component 2 adopts a rotary cylinder or a pneumatic wrench because it uses compressed air as the power source, has a larger torque and faster speed than a motor, and has no electrical risk.
[0041] As a specific implementation manner, in this embodiment, a socket hole is provided on the end face of the power output end of the driving component 2, and the socket hole has a taper, presenting a state where the blind end size is small and the opening end size is large. The tool shank 111 has the same taper as the socket hole, that is, the cross-sectional dimension of the tool shank 111 gradually increases along the direction away from the driving component 2. The upper end of the tool shank 111 is inserted into the socket hole, and the connection and fixation with the power output end of the driving component 2 are achieved by wedging. Exemplarily, the tapers of the socket hole and the tool shank 111 are both 0.5°.
[0042] As a specific embodiment, in this embodiment, the cross-section of the tool shank 111 is in a regular hexagon structure. Correspondingly, the cross-section of the insertion hole is in a regular hexagon structure that matches the tool shank 111.
[0043] Furthermore, in order to prevent the cleaning component 1 from falling off the driving component 2 during operation. As Figure 5 and Figure 6 shown, a limiting boss 1111 in a ring structure is provided on the tool shank 111. A stop block 31 is provided on the side of the limiting boss 1111 facing away from the driving component 2. Guide posts 32 extending towards the driving component 2 are respectively provided at both ends of the stop block 31, and the guide posts 32 are parallel to the tool shank 111. Guide seats 21 corresponding to the guide posts 32 one by one are provided on the outer shell of the driving component 2. Guide holes that cooperate with the guide posts 32 are provided on the guide seats 21. One end of the guide post 32 facing away from the stop block 31 passes through the guide hole of the corresponding guide seat 21 and extends to the side of the guide seat 21 facing away from the stop block 31. A stop member 33 is provided on the side of the guide post 32 facing away from the stop block 31 and located on the guide seat 21. A second spring 34 is sleeved between the stop member 33 and the guide seat 21 on the guide post 32. The stop block 31 is pressed upwards against the limiting boss 1111 under the elastic force of the second spring 34. The second spring 34 can make the stop block 31 abut against the limiting boss 1111, thereby providing a hard limit for the tool shank 111. At the same time, the existence of the second spring 34 can also make the stop block 31 in a floating state, thereby avoiding excessive pressure between the stop block 31 and the limiting boss 1111 and causing a problem of large frictional force.
[0044] As a specific embodiment, in this embodiment, the stop member 33 is a nut and is connected to the guide post 32 by a threaded connection.
[0045] As a specific embodiment, in this embodiment, the stop block 31 is located on one side of the tool shank 111, and an avoidance notch 311 for accommodating the tool shank 111 is provided on the stop block 31. The avoidance notch 311 is in an arc structure and is coaxially arranged with the tool shank 111.
[0046] Furthermore, as Figure 6 shown, both ends of the stop block 31 are respectively rotatably connected to the lower ends of the guide posts 32 through hinge shafts.
[0047] The reason for such a design is that since the tool handle 111 has a certain length, it may bend or deflect to a certain extent during operation. By designing the stopper 31 that plays a limiting role into a rotatable structure, the deformation generated by the tool handle 111 during operation can be absorbed, avoiding interference with the stopper 31.
[0048] As Figure 10 and Figure 11 shown, the tool holder 112 includes an upper cross plate 1121 and a lower cross plate 1122, and connecting columns 1123 are arranged between the upper cross plate 1121 and the lower cross plate 1122. The upper end of the connecting column 1123 is fixedly connected to the upper cross plate 1121 by welding, and the connection point of the connecting column 1123 and the upper cross plate 1121 is located at the geometric center of the upper cross plate 1121. The lower end of the connecting column 1123 is fixedly connected to the lower cross plate 1122 by welding, and the connection point of the connecting column 1123 and the lower cross plate 1122 is located at the geometric center of the lower cross plate 1122.
[0049] As Figure 3 and Figure 4 shown, the tool 12 is located between the upper cross plate 1121 and the lower cross plate 1122. A first guiding chute 11211 is arranged on the lower side surface of the upper cross plate 1121, and the upper end portion of the tool 12 is inserted into the first guiding chute 11211 and forms a guiding fit with the first guiding chute 11211. A second guiding chute 11221 that cooperates with the tool 12 is arranged on the upper side surface of the lower cross plate 1122. The first spring 13 is located between the connecting column 1123 and the tool 12. One end of the first spring 13 is fixedly connected to the connecting column 1123, and the other end of the first spring 13 is fixedly connected to the tool 12.
[0050] Furthermore, as Figure 3 and Figure 4 shown, several tools 12 are arranged between the upper cross plate 1121 and the lower cross plate 1122, and the several tools 12 are evenly arranged in a circumferential direction around the connecting column 1123. As a specific implementation manner, four tools 12 are arranged between the upper cross plate 1121 and the lower cross plate 1122 in this embodiment.
[0051] Furthermore, as Figure 3 and Figure 9As shown, an avoidance groove 1211 with an opening facing inward (the side closer to the connecting column 1123 along the radial direction is defined as the inner side) is provided at the lower end of the tool 12. The lower cross plate 1122 is inserted into the avoidance groove 1211, and the upper side edge of the avoidance groove 1211 is inserted into the second guiding sliding groove 11221 and forms a guiding fit with the second guiding sliding groove 11221.
[0052] The reason for such a design is that, as Figure 8 shown, during the cleaning operation, the outer edge of the tool 12 can contact the side wall of the carbon bowl 42, and the lower edge of the tool 12 can contact the bottom surface of the carbon bowl 42 and avoid the boss 43 at the bottom of the carbon bowl 42. In this way, the side wall and the bottom surface of the carbon bowl 42 can be cleaned simultaneously, improving the cleaning effect.
[0053] Furthermore, as Figure 9 shown, the tool 12 includes a blade 121 and a tool head 122 disposed outside the blade 121. The blade 121 is made of stainless steel, and the tool head 122 is made of diamond. The blade 121 and the tool head 122 are welded together by brazing. The diamond tool head 122 has high strength and long service life, reducing the replacement cost of the tool 12 while ensuring the cleaning effect.
[0054] Furthermore, as Figure 8 shown, the cutting edge of the tool 12 is of an inclined structure and has the same inclination as the side wall of the carbon bowl 42.
[0055] The reason for such a design is that, as Figure 7 and Figure 8 shown, the pre-baked anode 4 includes an anode body 41 and a carbon bowl 42. The diameter of the top of the carbon bowl 42 is larger than that of the bottom, and its side wall has a slope. By making the cutting edge of the tool 12 of an inclined structure, when the cleaning component 1 is inserted into the carbon bowl 42, the cutting edge of the tool 12 is parallel to the side wall of the carbon bowl 42, ensuring the cleaning effect on the side wall of the carbon bowl 42.
[0056] As Figure 10 shown, a strengthening connection structure is provided between the tool holder 112 and the tool handle 111. The strengthening connection structure includes an end plate 1131, and the end plate 1131 is fixedly connected to the end face of the tool handle 111 by welding. A plurality of rib plates 1132 extending radially are provided between the end plate 1131 and the upper cross plate 1121. The plurality of rib plates 1132 are arranged radially and evenly in the circumferential direction.
[0057] Furthermore, as Figure 1 and Figure 2As shown, a handle 22 and a lifting lug 23 are provided on the outer casing of the driving component 2.
[0058] When cleaning the carbon bowl 42, first, the entire pre-baked anode carbon bowl cleaning device is lifted by a lifting tool. An operator holds the handle 22 and places the end of the cleaning component 1 into the carbon bowl 42. At this time, since the cutting tool 12 is in a retracted state, the overall outer diameter of the end of the cleaning component 1 is smaller than the inner diameter of the carbon bowl 42, so it can enter the carbon bowl 42 without damage. Then, the device is started. The cleaning component 1 rotates driven by the driving component 2. When the cleaning component 1 rotates, the cutting tool 12 will overcome the elastic force of the first spring 13 and move away from the rotation center axis along the first guiding chute 11211 and the second guiding chute 11221 under the action of centrifugal force. At this time, the first spring 13 is stretched by the force. In this state, the cutting tool 12 is in a floating state, forming a relative transitional fit with the side wall and bottom of the carbon bowl 42. Through the grinding of the cutting tool 12, the metallurgical coke particles attached to the side wall and bottom of the carbon bowl 42 are cleaned off. After the cleaning is completed, the switch is turned off, the driving component 2 stops working, the centrifugal force disappears, and the elastic restoring force of the first spring 13 will drive the cutting tool 12 to retract. After the cleaning component 1 returns to the state when it is stationary, the operator can pull out the cleaning component 1 from the carbon bowl 42 through the handle 22.
