Description
Technical Field
[0001] This invention relates to the field of graphite electrode cleaning devices, and particularly to a graphite electrode cleaning device and cleaning method. Background Technology
[0002] Graphite electrode cleaning devices are specialized equipment used to remove impurities, deposits, or wear residues from the surface of graphite electrodes. They are mainly used in industrial settings such as metallurgy (e.g., electric arc furnace steelmaking), chemical industry, and photovoltaics, where graphite electrodes are used for high-temperature heating or electrical conduction.
[0003] Current graphite electrode cleaning devices typically place the graphite electrode on a frame and transport it via a chain or other conveyor structure. Generally, a guide plate or flipping mechanism is installed between the frame and the cleaning device to transfer the graphite electrode from the frame to between two sets of support rollers in the cleaning device. However, in actual use, the impact force between the graphite electrode and the support rollers during the transfer process is too great, which is not conducive to protecting the graphite electrode. This problem is particularly prominent when the diameter of the graphite electrode is large. Furthermore, when the diameter of the graphite electrode is large and the rolling speed is fast, the graphite electrode may overshoot the support rollers.
[0004] Therefore, it is necessary to provide a graphite electrode cleaning device and cleaning method to solve the above-mentioned technical problems. Summary of the Invention
[0005] The purpose of this invention is to provide a graphite electrode cleaning device and cleaning method to solve the problem in the prior art where a guide plate or flipping mechanism is set between the frame and the cleaning device so that the graphite electrode can be transferred from the frame to between two sets of support rollers in the cleaning device. However, in actual use, the impact force between the graphite electrode and the support rollers during the transfer process is too large.
[0006] Based on the above ideas, the present invention provides the following technical solution: a graphite electrode cleaning device, comprising a frame and a conveying unit mounted on the frame, a housing arranged at the rear end of the frame, a circumferential cleaning assembly arranged inside the housing, and further comprising: A feeding rack is located between the housing and the frame. The feeding rack is rotatably configured to feed the graphite electrode on the frame into the housing between the main support roller and the auxiliary support roller. An adjusting component and a supporting component are slidably mounted on the feeding frame. The adjusting component is used to measure the diameter of the graphite electrode at the top of the support. The supporting component can adjust its position on the feeding frame according to the measured diameter of the graphite electrode, so that after the graphite electrode falling on the top of the supporting component is deflected to a horizontal state, the axis of the graphite electrode can be located between the main support roller and the secondary support roller.
[0007] As a further aspect of the present invention: the feeding rack is provided with two sets of through slots for the adjustment member and the support member to slide, and the adjustment member is located above the frame.
[0008] As a further aspect of the present invention: multiple sets of support blocks are elastically arranged on the outer side of the feeding rack, one end of each support block can extend into the through groove where the support member is located to limit the position of the support member, and the multiple sets of support blocks are arranged sequentially along the length direction of the feeding rack.
[0009] As a further aspect of the present invention: a slide rod is provided above the support block, and the slide rod has two inclined extrusion sections and a vertical holding section located between the two extrusion sections on one side near the feeding frame. The support block is provided with a groove that cooperates with the slide rod. A traction member is fixedly provided between the adjusting member and the slide rod. When the graphite electrode pushes the adjusting member upward, the traction member can release the slide rod downward. The extrusion of the inclined extrusion section on the slide rod and the side edge of the groove can cause one end of the support block to extend into the through groove.
[0010] As a further aspect of the present invention: the end of the traction member away from the adjusting member passes upward through the feeding frame and then folds back and is fixedly connected to the slide rod.
[0011] As a further aspect of the present invention, the top of the frame and the portion near the feeding rack are inclined.
[0012] As a further aspect of the present invention: the feeding rack is inclined on one side near the frame, so that the graphite electrode can always be in contact with one side of the support during the process of the feeding rack rotating to a horizontal state.
[0013] As a further aspect of the present invention: the feeding rack has a plate-like structure and the feeding rack can rotate around the rotation center inside the box.
[0014] As a further aspect of the present invention: a driving component is arranged inside the box, and the telescopic end of the driving component is hinged to the feeding frame, so that the driving component can drive the feeding frame to rotate around the rotation center.
[0015] A cleaning method using the above-mentioned graphite electrode cleaning device includes the following steps: conveying the graphite electrode to one side of the feeding frame via a conveying unit; driving the feeding frame to rotate, and using the cooperation between the feeding frame and the support member to convey the graphite electrode into the box and place it between the main support roller and the auxiliary support roller; and cleaning the surface of the graphite electrode by a circumferential cleaning component.
[0016] Compared with the prior art, the beneficial effects of the present invention are: by setting a rotatable feeding frame, the graphite electrode can be stably fed between the main support roller and the auxiliary support roller. Furthermore, when the diameter of the graphite electrode increases, by adjusting the position of the support member relative to the feeding frame, the graphite electrode can be deflected to a horizontal state by the feeding frame, and the axis of the graphite electrode can also be located between the main support roller and the auxiliary support roller, thereby providing conditions for the graphite electrode to fall stably between the main support roller and the auxiliary support roller.

Detailed Implementation
[0019] like Figures 1-10As shown, a graphite electrode cleaning device includes a frame 1 for supporting a graphite electrode 9 and a conveying unit 2 disposed on the frame 1 for conveying the graphite electrode 9. A housing 4 is arranged at the tail end of the frame 1. The housing 4 is equipped with a rotary support 6, a circumferential cleaning assembly 7, and an end face cleaning assembly 8. A deflectable feeder 3 is disposed between the housing 4 and the frame 1. The feeder 3 is configured to convey the graphite electrode 9 at the top of the frame 1 to the rotary support 6 inside the housing 4. The rotary support 6 can support the graphite electrode 9 and drive it to rotate. The circumferential cleaning assembly 7 is used to clean the outer circumferential surface of the graphite electrode 9, while the end face cleaning assembly 8 can clean the end of the graphite electrode 9. The feeder 3 can be selectively arranged on the outside of the frame 1 to avoid interference with the frame 1 during rotation.
[0020] Combination Figures 2-5 As shown, the feeding rack 3 has a plate-like structure and can rotate around the rotation center 10 inside the box 4. Furthermore, a driving component 11, such as a hydraulic rod or electric cylinder, is arranged inside the box 4. Specifically, the tail end of the driving component 11 is hinged to the box 4, and the telescopic end of the driving component 11 is hinged to the hinge seat near the bottom of the feeding rack 3, so that the driving component 11 can drive the feeding rack 3 to rotate around the rotation center 10.
[0021] An adjusting member 301 and a supporting member 302 are slidably mounted on the feeding rack 3. Specifically, the adjusting member 301 is used to measure the diameter of the graphite electrode 9 at the top of the frame 1, while the supporting member 302 adjusts its position relative to the feeding rack 3 according to the measured diameter of the graphite electrode 9. This ensures that after the graphite electrode 9 resting on the top of the supporting member 302 is deflected to a horizontal position, the axis of the graphite electrode 9 is located between the main support roller 601 and the auxiliary support roller 602 within the housing 4. Figure 4 As shown.
[0022] In traditional cleaning devices, an inclined guide plate is typically installed between the frame 1 and the rotary support 6 to conduct the graphite electrode 9 between the main support roller 601 and the auxiliary support roller 602. Although the structure is relatively simple, the graphite electrode 9 is easily damaged when it collides with the rotary support 6, especially when the diameter of the graphite electrode 9 is large. Furthermore, when the diameter of the graphite electrode 9 is large and the rolling speed is fast, the graphite electrode 9 may overshoot the rotary support 6. In contrast, the proposed solution... By setting a rotatable feeding frame 3, the graphite electrode 9 can be stably fed between the main support roller 601 and the auxiliary support roller 602. Furthermore, when the diameter of the graphite electrode 9 increases, by adjusting the position of the support member 302 relative to the feeding frame 3, the graphite electrode 9 can be deflected to a horizontal state by the feeding frame 3. At this time, the axis of the graphite electrode 9 can also be located between the main support roller 601 and the auxiliary support roller 602, thereby providing conditions for the graphite electrode 9 to fall stably between the main support roller 601 and the auxiliary support roller 602.
[0023] Specifically, Figure 4 The graphite electrode 9 in the middle is a standard size with a small diameter. As the feeder 3 deflects to a horizontal position, this graphite electrode 9 can fall between the main support roller 601 and the auxiliary support roller 602 and fit against them. Figure 6 as well as Figure 7 The diagrams shown are of graphite electrodes 9 with larger diameters that rotate with the feed frame 3 to the vicinity of the rotary support 6. The only difference is that... Figure 7 The support 302 is fixed relative to the feeding frame 3, as shown in the figure. Figure 7 As shown, when the larger diameter graphite electrode 9 deflects with the feed frame 3 to the vicinity of the rotary support 6, the graphite electrode 9 will first contact the main support roller 601, and the minimum distance between the graphite electrode 9 and the auxiliary support roller 602 is S2; while Figure 6 The support member 302 shown is movable relative to the feed frame 3. In this case, when the graphite electrode 9 with a larger diameter deflects to the vicinity of the rotary support member 6 along with the feed frame 3, it will first come into contact with the auxiliary support roller 602. Afterward, the graphite electrode 9 can deflect towards the main support roller 601 with the auxiliary support roller 602 as the fulcrum until it is completely in contact with both the main support roller 601 and the auxiliary support roller 602. Figure 6 In the process, after the graphite electrode 9 first contacts the secondary support roller 602, the minimum distance between the graphite electrode 9 and the main support roller 601 is S1. Figures 6-7 As can be seen, the spacing S1 is smaller than the spacing S2. Therefore, when the support member 302 is adjustable relative to the feeder 3, the graphite electrode 9 experiences the least impact force when falling between the main support roller 601 and the secondary support roller 602, thus protecting the graphite electrode 9. Furthermore, the graphite electrode 9 will not interfere with the support member 302 when falling between the main support roller 601 and the secondary support roller 602.
[0024] The feeding rack 3 is provided with two sets of through slots for the adjustment member 301 and the support member 302 to slide respectively. The adjustment member 301 is located above the frame 1. Multiple sets of support blocks 15 are slidably arranged on the outer side of the feeding rack 3. The support blocks 15 are located at the support member 302. Figure 3 , Figure 5 as well as Figures 3-10 As shown, one end of the support block 15 can extend into the through groove where the support member 302 is located to limit the support member 302, so that the support member 302 can stably support the graphite electrode 9 during the deflection of the feeder 3. Multiple sets of support blocks 15 are arranged sequentially along the length of the feeder 3. When the support member 302 is located at different positions on the feeder 3, the support member 302 can be limited by the corresponding support block 15. Therefore, each support block 15 needs to be arranged according to the graphite electrode 9 of different sizes. Furthermore, a slide rod 14 is provided above the support block 15, and the slide rod 14 has two inclined extrusion sections 1401 and a vertical holding section 1402 located between the two extrusion sections 1401 on one side near the feeding frame 3. The support block 15 is provided with a slot 1501 that mates with the slide rod 14. A traction member 17 is fixedly provided between the adjusting member 301 and the slide rod 14. Specifically, the end of the traction member 17 away from the adjusting member 301 passes upward through the feeding frame 3 and then folds back and is fixedly connected to the slide rod 14. When the graphite electrode 9 with a larger diameter is carried by... When the conveying unit 2 moves to the feeding rack 3, the graphite electrode 9 can lift the adjusting member 301 upwards. During the upward movement of the adjusting member 301, the traction member 17 releases the sliding rod 14, allowing the sliding rod 14 to move downwards. Through the weight of the sliding rod 14 itself, the pressure between the inclined pressing part 1401 on the sliding rod 14 and the side edge of the slot 1501 can drive one end of the support block 15 into the through slot, allowing the support member 302 to fall onto the top of the support block 15 as it descends along the feeding rack 3. Therefore, when the diameter of the graphite electrode 9 is large, the sliding rod 14 can... Figure 9 One end of the support block 15 at the lower position is pressed into the through groove to support the support member 302, so that when the support member 302 supports the graphite electrode 9 and drives it to deflect to a horizontal state, the axis of the graphite electrode 9 can be located between the main support roller 601 and the auxiliary support roller 602.
[0025] In summary, the above structure, through the arrangement of multiple sets of support blocks 15 and the combination of slide rods 14 and adjusting members 301, allows the support blocks 15 at different positions to cooperate with the support member 302 according to the diameter of the graphite electrode 9. This ensures that when the graphite electrode 9 deflects with the feed frame 3 to the vicinity of the rotary support member 6, it can first contact the auxiliary support roller 602. Of course, this is only one embodiment for adjusting the position of the support member 302. In actual use, the position of the support blocks 15 can also be adjusted by electronic control. In this method, only one set of support blocks 15 needs to be set, and... An electric cylinder is installed on the feeding rack 3. The telescopic end of the electric cylinder is fixedly connected to the support block 15 to adjust the position of the support block 15 relative to the feeding rack 3. The feeding rack 3 needs to be provided with a sliding groove for the support block 15 to slide up and down. In addition, a position detection component, such as an infrared sensor or an ultrasonic sensor, needs to be installed at the top of the feeding rack 3 to detect the diameter of the graphite electrode 9 and control the operation of the electric cylinder. In this embodiment, the support block 15 is adjusted by electronic control. The structure is simple but the cost is high. Furthermore, the stability of the support block 15 supporting the support member 302 is weaker than that of the previous embodiment.
[0026] Combination Figures 1-2 , Figure 5 , Figure 8 As shown, the portion of the top of the frame 1 and near the feeding rack 3 is inclined and denoted as... Figure 8 The letter L in the diagram allows the graphite electrode 9 to slowly roll downwards to the side of the feeder 3 when the conveying unit 2 delivers it to this section; the side of the feeder 3 closest to the frame 1 is denoted as L. Figure 5 Specifically, the side of the feeder 3 closest to the frame 1 is inclined, meaning that the side of the m-face closest to the adjusting member 301 is more protruding than the side of the m-face closest to the support member 302. This allows the graphite electrodes 9 to adhere to the support member 302 side during the process of the feeder 3 being deflected to a horizontal state.
[0027] The housing 4 is equipped with a transverse pushing component 5, such as a cylinder or an electric push rod. The telescopic end of the transverse pushing component 5 is fixedly connected to the end face cleaning component 8 to adjust the position of the end face cleaning component 8 so that it contacts the end face of the graphite electrode 9 located on the rotary support 6. In addition, the housing 4 is also equipped with a longitudinal pushing component, such as a cylinder or an electric push rod. The telescopic end of the longitudinal pushing component is fixedly connected to the circumferential cleaning component 7 to adjust the position of the circumferential cleaning component 7 so that it contacts the outer circumferential surface of the graphite electrode 9 located on the rotary support 6. It should be noted that both the end face cleaning component 8 and the circumferential cleaning component 7 are composed of plate-shaped connecting parts and wire brushes or sanding belts set on the connecting parts, which is beneficial for cleaning the surface of the graphite electrode 9.
[0028] The conveying unit 2 can be a belt or chain, etc. The conveying unit 2 is sleeved between two sets of shafts on the frame 1, and the shafts are driven to rotate by an external motor. It should be noted that the top of the conveying unit 2 protrudes from the frame 1 to convey the graphite electrode 9.
[0029] Combination Figures 2-3 As shown, multiple sets of rotary support members 6 are provided, and the feeding rack 3 and other structures can be positioned between two adjacent sets of rotary support members 6 during the deflection process. Specifically, multiple sets of bases are installed inside the housing 4, and the rotary support member 6 is rotatably connected to the base through a connecting shaft at its end. It can selectively be connected to the connecting shaft on one or more sets of rotary support members 6 via a motor to drive the graphite electrode 9 to rotate. Of course, the connecting shaft on the main support roller 601 and the connecting shaft on the auxiliary support roller 602 in the rotary support member 6 can be connected by belt or chain drive. An opening is provided on the side of the housing 4 away from the frame 1, so that the cleaned graphite electrode 9 can be removed through the opening. Specifically, the graphite electrode 9 can be removed by a forklift or the auxiliary support roller 602 can be driven upward to push out the graphite electrode 9.
[0030] The rotation center 10 is a horizontal axis, which is fixedly or rotatably connected to the housing 4. A base 303 is fixedly installed on the feeding rack 3. The horizontal axis passes through the base 303 and rotates with it. The base 303 is located above the driving component 11.
[0031] Combination Figure 5 As shown, a limiting member 12 is provided on the outer side of the frame 1. In one embodiment, the limiting member 12 is fixedly connected to the frame 1. When the feeding rack 3 deflects in the opposite direction and resets, the support member 302 can be located on top of the limiting member 12 and contact it. When the feeding rack 3 rotates to a vertical state, the limiting member 12 can lift the support member 302 upward and reset it, which is beneficial for the next use. In another embodiment, the limiting member 12 can be fixedly connected to an external electric cylinder. When the support member 302 is reset, the electric cylinder drives the limiting member 12 to move upward and push the support member 302 to reset.
[0032] from Figure 5 As can be seen, the bottom of the adjusting member 301 is set as an inclined surface, so that the adjusting member 301 can be pushed upward by this inclined surface as the graphite electrode 9 rolls to one side of the feeding rack 3.
[0033] Figure 8The image shows the support 302 gradually deflecting upwards and coming into contact with the graphite electrode 9. It should be noted that as the feeder 3 deflects and the graphite electrode 9 remains in contact with one side of the feeder 3, although the position of the adjusting member 301 relative to the feeder 3 moves, the holding part 1402 on the slide rod 14 remains within the slot 1501 on the support block 15 to maintain the stability of the support block 15.
[0034] Reference Figure 3 , Figure 9 As shown, both the support member 302 and the adjusting member 301 are equipped with two sets of rollers, which are located on both sides of the feeding frame 3 to maintain the stability of the support member 302 and the adjusting member 301. A sleeve 13 is fixedly installed on the feeding frame 3, and the sliding rod 14 passes through the sleeve 13 and slides with it. A pulley is installed at the top of the feeding frame 3, and the aforementioned traction member 17 can be a steel wire rope or a nylon rope, etc., and the traction member 17 passes around the outside of the pulley.
[0035] Reference Figure 10 As shown, guide rods 16 are provided on both sides of the support block 15. The guide rods 16 are fixedly connected to the feeding frame 3. A protrusion is fixedly provided on the side of the support block 15. The guide rods 16 pass through the protrusion and slide with it. A spring connecting the protrusion and the feeding frame 3 is sleeved on the outside of the guide rod 16 to realize the elastic cooperation between the support block 15 and the feeding frame 3. When the extrusion part 1401 is misaligned with the slot 1501, one end of the support block 15 can be moved out of the through slot.
[0036] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
