Description

Technical Field

[0001] This utility model belongs to the field of electrode cleaning technology, specifically relating to a calcined electrode cleaning machine. Background Technology

[0002] Currently, graphite electrodes that have undergone calcination and graphitization processes typically have a significant amount of binder material and a dense coking layer adhering to their outer surface. This needs to be thoroughly cleaned to avoid affecting subsequent processing, and shot blasting is a common cleaning method. However, existing conventional shot blasting equipment is inconvenient to load and unload in practical use, often requiring manual assistance, which is time-consuming and labor-intensive. Furthermore, the cleaning process generates dust pollution, which needs improvement. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a calcination electrode cleaning machine that can achieve convenient automatic loading and unloading and can effectively remove dust, so as to solve the above problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a calcined electrode cleaning machine, comprising a cleaning chamber, wherein the left side of the cleaning chamber is closed and the right side is open, and a roller conveyor is provided outside the open side of the cleaning chamber. The conveying roller on the roller conveyor is formed by joining the small-diameter ends of two conical rollers. Supports are fixedly provided on the lower left and right sides of the inner end walls of the front and rear of the cleaning chamber, and a rotating shaft is rotatably provided on each support. A roller is fixedly connected between two rotating shafts on the same end wall. One rotating shaft passes through the corresponding support and is connected to a motor for transmission. A hydraulic cylinder is horizontally fixedly provided above the gap between the two rollers on the left side wall of the cleaning chamber. The piston rod of the hydraulic cylinder faces to the right and is fixedly connected to a push plate. A shot blasting head is installed inside the top of the cleaning chamber. A first inverted U-shaped tube and a U-shaped tube are fixedly provided on the outer top of the cleaning chamber. The system comprises a first inverted U-shaped tube, a second inverted U-shaped tube, an L-shaped tube, and an exhaust fan. One end of the first inverted U-shaped tube is connected to the top of the cleaning chamber, and the other end corresponds vertically to one end of the U-shaped tube, with a first dust removal tube detachably installed between the two ends. The other end of the U-shaped tube corresponds vertically to one end of the second inverted U-shaped tube, with a second dust removal tube detachably installed between the two ends. The other end of the second inverted U-shaped tube corresponds vertically to the top of the L-shaped tube, with a third dust removal tube detachably installed between the two ends. The bottom end of the L-shaped tube is connected to the air inlet of the exhaust fan. Several dust removal screens are fixedly installed vertically at intervals in the first, second, and third dust removal tubes. The dust removal screens in the same dust removal tube have the same pore size, and the pore size of the dust removal screens in different dust removal tubes decreases from the first dust removal tube to the second dust removal tube to the third dust removal tube. Activated carbon is filled between two adjacent dust removal screens.

[0005] Preferably, electric push rods are fixedly installed on the left and right sides of the first inverted U-shaped tube corresponding to one end of the U-shaped tube, on the left and right sides of both ends of the U-shaped tube, on the left and right sides of both ends of the second inverted U-shaped tube, and on the left and right sides of the top end of the L-shaped tube. Square limiting seats are fixedly sleeved on the port of the first inverted U-shaped tube corresponding to one end of the U-shaped tube, on the ports of both ends of the U-shaped tube, on the ports of both ends of the second inverted U-shaped tube, and on the port of the top end of the L-shaped tube. First blind grooves are opened on the left and right sides of the limiting seats. A movable plate is fixedly connected to the telescopic end of the electric push rod. A U-shaped limiting block is fixedly connected to the end of the movable plate near the adjacent limiting seat. Square positioning seats are fixedly sleeved at the top and bottom ends of the first dust removal tube, the second dust removal tube, and the third dust removal tube. Second blind grooves are opened on the left and right sides of the positioning seats. The positioning seats abut against the adjacent positioning seats. The two ends of the limiting blocks correspond to and are inserted into the adjacent first and second blind grooves.

[0006] Preferably, the positioning seat is adapted to the corresponding limiting seat.

[0007] Preferably, the limiting block is adapted to the corresponding first blind slot and second blind slot.

[0008] Preferably, a sealing gasket is fixed on the side of the limiting seat near the corresponding positioning seat.

[0009] The beneficial effects of this invention are as follows: When shot blasting the calcined electrode, the electrode can be placed on a roller conveyor, which drives it forward for feeding. The conveyor rollers on the roller conveyor are formed by two conical rollers joined together. This structure effectively ensures the electrode is centered during forward conveying, preventing the electrode from shifting or misaligning during transport, and is more conducive to subsequent cleaning processing. After the electrode is conveyed onto the two idler rollers by the roller conveyor, the roller conveyor stops running, and the motors corresponding to the idler rollers start running, driving the two idler rollers to rotate, thereby driving the electrode to rotate. At the same time, the shot blasting head operates, throwing out shot blasting material to clean the upper side of the electrode. This, combined with the rotation of the electrode, achieves comprehensive shot blasting treatment of the electrode surface. After cleaning, the hydraulic cylinder actuates, and its piston rod extends, which pushes the electrode out of the cleaning chamber and back onto the roller conveyor via a push plate. Then, the conveyor rollers on the roller conveyor rotate in the opposite direction, driving the cleaned electrode to be unloaded. In this way, automatic loading and unloading of electrodes can be achieved, which is simple to operate, saves more time and labor, and is more convenient to use overall.

[0010] During the cleaning process, the exhaust fan operates, drawing away the dusty air generated in the cleaning chamber through the first inverted U-shaped pipe. The dusty air then flows sequentially through the first inverted U-shaped pipe, the first dust removal pipe, the U-shaped pipe, the second dust removal pipe, the second inverted U-shaped pipe, the third dust removal pipe, and the L-shaped pipe before being discharged through the exhaust fan's outlet. When the dusty air passes through the first dust removal pipe, it is treated by the dust filter and activated carbon inside, achieving multiple stages of interception and adsorption filtration. When the dusty air passes through the second dust removal pipe, it is treated by the dust filter and activated carbon inside, which have smaller pore sizes than those in the first dust removal pipe, achieving multiple stages of interception and adsorption filtration. When the dusty air passes through the third dust removal pipe, it is treated by the dust filter and activated carbon inside, which have smaller pore sizes than those in the second dust removal pipe, achieving multiple stages of interception and adsorption filtration. This effectively purifies the dust generated during cleaning, making it more environmentally friendly and practical. In addition, the first, second, and third dust removal pipes can all be flexibly disassembled and replaced, which can better ensure the dust removal quality and make the overall use more flexible and convenient.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 7 As shown, a calcined electrode cleaning machine includes a cleaning chamber 1, which is closed on the left and open on the right. A roller conveyor 2 is installed outside the open side of the cleaning chamber 1. The conveying rollers 3 on the roller conveyor 2 are formed by joining the smaller diameter ends of two conical rollers. Supports 4 are fixedly installed on the lower left and right sides of the inner end walls at both the front and rear ends of the cleaning chamber 1. A rotating shaft 5 is rotatably mounted on each support 4. A roller 6 is fixedly connected between two rotating shafts 5 on the same end wall. One rotating shaft 5 passes through the corresponding support 4 and is connected to a motor 7 for transmission. A hydraulic cylinder 8 is horizontally fixedly installed above the gap between the two rollers 6 on the left side wall of the cleaning chamber 1. The piston rod of the hydraulic cylinder 8 faces to the right and is fixedly connected to a push plate 9. A shot blasting head 10 is installed inside the top of the cleaning chamber 1. A first inverted U-shaped pipe 11, a U-shaped pipe 12, a second inverted U-shaped pipe 13, an L-shaped pipe 14, and an exhaust fan 15 are fixedly installed on the outer top of the cleaning chamber 1. One end of the first inverted U-shaped pipe 13 is connected to the top of the cleaning chamber 1, and the other end corresponds vertically to one end of the U-shaped pipe 12. A first dust removal pipe 16 is detachably installed between these two ends. The other end of the U-shaped pipe 12 corresponds vertically to one end of the second inverted U-shaped pipe 13, and a second dust removal pipe 17 is detachably installed between these two ends. The other end of the second inverted U-shaped pipe 13 is connected to the L-shaped pipe 14. The top of the tube is detachably provided with a third dust removal tube 18 between the two ends. The bottom end of the L-shaped tube 14 is connected to the air inlet of the exhaust fan 15. Several dust removal nets 19 are fixedly provided in the first dust removal tube 16, the second dust removal tube 17 and the third dust removal tube 18 at vertical intervals. The pore size of the dust removal nets 19 in the same dust removal tube is the same. The pore size of the dust removal nets 19 in different dust removal tubes decreases from the first dust removal tube 16, the second dust removal tube 17 to the third dust removal tube 18. Activated carbon 20 is filled between two adjacent dust removal nets 19.

[0021] When shot blasting the calcined electrodes, the electrodes are first placed on the roller conveyor 2, which drives them forward. The conveyor roller 3 on the roller conveyor 2 is composed of two conical rollers joined together. This structure effectively ensures the electrodes are centered during transport, preventing them from shifting or becoming misaligned, and is more conducive to subsequent cleaning. After the electrodes are conveyed onto the two idler rollers 6 by the roller conveyor 2, the roller conveyor 2 stops running, and the motor 7 corresponding to the idler rollers 6 starts, driving the two idler rollers 7 to rotate, thereby driving the electrodes to rotate. At the same time, the shot blasting head 10 operates, throwing out shot blasting material to clean the upper side of the electrodes. This, combined with the rotation of the electrodes, achieves comprehensive shot blasting treatment of the electrode surface. After cleaning, the hydraulic cylinder 8 actuates, and its piston rod extends, which pushes the electrodes out of the cleaning chamber 1 via the push plate 9 and pushes them back onto the roller conveyor 2. Then, the conveyor roller 3 on the roller conveyor 2 rotates in the opposite direction, driving the cleaned electrodes to be unloaded. This enables automatic loading and unloading of electrodes, making operation simple, saving time and effort, and making overall use more convenient;

[0022] During the cleaning process, the exhaust fan 15 operates, which can draw away the dusty air generated in the cleaning chamber 1 through the first inverted U-shaped pipe 11, and make the dusty air flow through the first inverted U-shaped pipe 11, the first dust removal pipe 16, the U-shaped pipe 12, the second dust removal pipe 17, the second inverted U-shaped pipe 13, the third dust removal pipe 18 and the L-shaped pipe 14 in sequence, and then discharge it through the exhaust port of the exhaust fan 15. When dusty air passes through the first dust collector 16, it is treated by the dust collector 19 and activated carbon 20 inside, achieving multiple primary interception and adsorption filtrations. When dusty air passes through the second dust collector 17, it is treated by the dust collector 19 (with smaller pores than the dust collector 19 in the first dust collector 16) and activated carbon 20, achieving multiple secondary interception and adsorption filtrations. When dusty air passes through the third dust collector 18, it is treated by the dust collector 19 (with smaller pores than the dust collector 19 in the second dust collector 17) and activated carbon 20, achieving multiple tertiary interception and adsorption filtrations. This effectively purifies the dust generated during cleaning, making it more environmentally friendly and practical. Furthermore, the first, second, and third dust collectors 16 and 18 can be flexibly disassembled and replaced, further ensuring dust removal quality and making overall use more flexible and convenient. Both the roller conveyor 2 and the shot blasting head 10 can be made using existing technologies, and their specific structures and working principles will not be described in detail here.

[0023] In this embodiment, electric push rods 21 are fixedly installed on the left and right sides of the corresponding end of the first inverted U-shaped tube 11 and U-shaped tube 12, the left and right sides of both ends of the U-shaped tube 12, the left and right sides of both ends of the second inverted U-shaped tube 13, and the left and right sides of the top end of the L-shaped tube 14. Square limiting seats 22 are fixedly sleeved on the ports of the corresponding end of the first inverted U-shaped tube 11 and U-shaped tube 12, the ports of both ends of the U-shaped tube 12, the ports of both ends of the second inverted U-shaped tube 13, and the top end of the L-shaped tube 14. The left and right sides of the limiting seats 22... Each of the tubes has a first blind groove 23. The telescopic end of the electric push rod 21 is fixedly connected to a movable plate 24. The end of the movable plate 24 near the adjacent limiting seat 22 is fixedly connected to a U-shaped limiting block 25. The top and bottom ends of the first dust removal pipe 16, the second dust removal pipe 17 and the third dust removal pipe 18 are all fixedly fitted with square positioning seats 26. The left and right sides of the positioning seat 25 are each provided with a second blind groove 27. The positioning seat 25 abuts against the adjacent limiting seat 22. The two ends of the limiting block 25 correspond to and are inserted into the adjacent first blind groove 23 and second blind groove 27. When it is necessary to replace the first dust removal pipe 16, the second dust removal pipe 17, and / or the third dust removal pipe 18, the corresponding electric push rod 21 can be operated in the stopped state to extend its telescopic end, which will drive the corresponding limit block 25 away from the corresponding limit seat 22 and positioning seat 26 until the end of the limit block 25 is pulled out from the corresponding first blind groove 23 and second blind groove 27, thereby releasing the insertion lock of the limit seat 22 and positioning seat 26. Then, the corresponding dust removal pipe can be moved away from the corresponding two limit seats 22 in the front-back direction to remove the original dust removal pipe. After obtaining the new dust collector pipe, simply install it between the two corresponding limit seats 22, then operate the electric push rod 21 to retract its telescopic end, causing the limit block 25 to approach the limit seat 22 until both ends are inserted into the corresponding first blind groove 23 and second blind groove 27. Then, insert and fix the limit seat 22 and positioning seat 26 to complete the fixed installation of the new dust collector pipe. The installation is secure and does not affect subsequent use. This allows for flexible and convenient disassembly and replacement of the corresponding dust collector pipe, better ensuring dust removal quality and making overall use more flexible and convenient.

[0024] In this embodiment, the positioning seat 25 is adapted to the corresponding limiting seat 22 to ensure that the two are properly connected.

[0025] In this embodiment, the limiting block 25 is adapted to the corresponding first blind slot 23 and second blind slot 27 to ensure that the limiting block 25 is inserted in place.

[0026] In this embodiment, a sealing gasket 28 is fixed on the side of the limiting seat 22 near the corresponding positioning seat 25 to ensure the sealing of the connection between the corresponding dust removal pipe and the corresponding pipeline, so as not to affect the dust removal operation.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
