Description

Technical Field

[0001] The invention relates to the technical field of graphite roasting equipment, in particular to a roasting equipment used for graphite production. Background Art

[0002] In the production of graphite products, roasting is an important step. By using roasting equipment to roast graphite products, impurities can be removed, the graphite structure can be improved, and the mechanical properties of graphite can be enhanced.

[0003] The existing roasting equipment used for graphite production is usually in the form of a ring roasting furnace or a tunnel kiln. The ring roasting furnace consists of a ring structure of multiple furnace chambers, each of which is usually in the shape of a rectangular parallelepiped or a cylinder. The furnace chambers are connected by fire channels to achieve heat transfer. When in use, the preliminarily formed graphite is placed in the furnace chamber, and the fire channels around the furnace chamber are heated by a heating mechanism to transfer heat to the graphite. Then, as the furnace body rotates or moves, the graphite goes through the preheating, roasting and cooling stages in sequence, and finally the roasting operation is completed. The roasting equipment in the form of a tunnel kiln is usually in the shape of a long strip. When in use, the preliminarily formed graphite is placed on a kiln car, which drives the graphite through the preheating zone and the roasting zone in sequence, and then cools it in the cooling zone to complete the roasting operation. In use, the roasting equipment in the form of ring roasting furnaces and tunnel kilns occupies a large area due to their structure. In addition, since the tunnel kiln is long, a large amount of energy is usually required to maintain the temperature in the kiln, which increases the production cost of graphite.

The three-dimensionally placed roasting box reduces the floor space, and since heat accumulates above the roasting box, energy consumption of the roasting operation is saved. Specifically:

[0013] 1. The driving sprocket drives the driving column to move periodically through the cooperation of the driving chain, and the driving column drives the supporting plate connected to its rotation to move synchronously. In this process, the sliding limit of the guide slide by the guide groove makes the direction of the supporting plate not change. Furthermore, the cooperation of the limiting rod and the supporting rod realizes the support of the graphite to be roasted after the initial formation. With the cooperation of the feeding mechanism and the discharging mechanism, the automatic feeding and discharging of the graphite are conveniently realized, which is convenient for continuous roasting of graphite, improves the efficiency of graphite roasting, reduces labor input, reduces production costs, and at the same time prevents operators from contacting the high-temperature roasting box, thereby improving the protection of operators.

[0014] 2. The feeding turntable rotates, and the feeding turntable drives the supporting arm to swing periodically through the cooperation of the eccentrically arranged feeding chute and the feeding slide column slidingly connected to the feeding chute. During the swinging process of the supporting arm, the swinging arm is driven to swing periodically through the connecting arm, thereby driving the feeding gear to rotate intermittently through the swinging rack. The feeding gear drives the feeding roller to rotate intermittently through the feeding connecting rod. The feeding roller drives the graphite to be roasted to move to the feeding mechanism, thereby conveniently realizing the automatic feeding operation of graphite and improving the efficiency of graphite roasting;

[0015] 3. During the swinging process, the support arm drives the limit slide plate to slide up and down periodically along the limit slide groove through the cooperation of the support rod and the limit sleeve. The limit slide plate drives the limit block to move synchronously through the limit slider, thereby realizing the limit block to periodically clamp, lock and release the feed gear, preventing the feed gear from rotating when the swing rack is not engaged with the feed gear, improving the rotation stability of the feed roller, avoiding slip damage to the graphite material to be roasted, and improving the protection of the graphite material to be roasted;

[0016] 4. The outlet filter plate filters the dust generated during the roasting process. The cleaning mechanism drives the cleaning blades to rotate through the wind force. The cleaning blades drive the cleaning bracket to rotate synchronously through the cleaning rotating column. The cleaning bracket drives the cleaning brush to rotate to brush and clean the outlet filter plate. At the same time, the cleaning spring drives the cleaning ball head to rotate. The cleaning ball head causes the outlet filter plate to vibrate slightly, which can easily shake off the dust, further avoid clogging of the outlet filter plate, maintain high-efficiency filtration of the outlet filter plate, and avoid dust pollution in the working environment.

[0031] The present invention will be described in further detail below with reference to the accompanying drawings.

[0032] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3 With attached Figure 4As shown, a roasting device for graphite production includes a roasting box 1, wherein the two ends of the roasting box 1 are respectively connected to each other and are provided with a feed port 11 and a discharge port 12, a heating room 13 is provided in the roasting box 1, and a heating mechanism 131 is provided in the heating room 13. The heating mechanism 131 can adopt the form of resistance heating. This is the current existing technology and is not described here. The roasting box 1 is provided with a material transfer mechanism 3 for transferring graphite from the feed port 11 to the discharge port 12, and the material transfer mechanism 3 includes a support plate 31 and a matching plate 37 arranged in the roasting box 1. The roasting box 1 is provided with a roasting chamber 15 and a driving chamber 16 on both sides of the support plate 31, and a heat insulation plate is provided in the roasting chamber 15. Two groups are set up, and a guide groove 311 is provided on the support plate 31 and the matching plate 37. The guide groove 311 is a square structure. A supporting mechanism 32 for supporting graphite is slidingly provided in the guide groove 311. A through hole for the supporting mechanism 32 to pass through is provided on the heat insulation plate. A feeding mechanism 33 for supporting the graphite to be roasted is provided on the side of the matching plate 37 close to the feed port 11, and a discharging mechanism 34 for supporting the roasted graphite is provided on the side of the matching plate 37 close to the discharge port 12. A driving mechanism 35 for driving the supporting mechanism 32 to move is provided in the roasting box 1, and a feeding mechanism 4 for transferring the graphite to be roasted to the feeding mechanism 33 as the driving sprocket 351 moves is provided in the roasting box 1.

[0033] The working principle of the present invention is as follows: two groups of insulation plates divide the roasting chamber 15 into three areas. With the cooperation of the heating mechanism 131, the temperature of the three areas increases from bottom to top. After preliminary forming, the graphite to be roasted enters the roasting box 1 through the feed port 11 and is placed on the feeding mechanism 33. The driving mechanism 35 drives the supporting mechanism 32 to move along the track of the guide chute 311. When passing through the feeding mechanism 33, the supporting mechanism 32 drives the graphite to be roasted placed on the feeding mechanism 33 to move synchronously. Since the guide chute 311 is a square structure, the movement track of the supporting mechanism 32 is also a square structure. During the movement process, the supporting mechanism 32 drives the graphite through the discharging mechanism 34 after passing through the preheating stage, the heating stage, the roasting stage, the cooling stage and the cooling stage. The graphite stays on the discharging mechanism 34 and moves out of the roasting box 1 through the discharging port 12 to complete the roasting operation.

[0034] Combined with attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 With attached Figure 7As shown, the supporting mechanism 32 includes a guide slide 324 slidingly arranged in the guide slide groove 311, and the guide slide 324 is provided with three groups. The three groups of guide slides 324 are arranged in a triangle. A supporting plate 321 is provided on the guide slide 324, and a limiting rod 322 and a supporting rod 323 are provided on one side of the supporting plate 321. The limiting rod 322 is symmetrically arranged on both sides of the supporting rod 323. The feeding mechanism 33 includes a feeding rack 331 provided on the matching plate 37, and a feeding rod 331 is provided on the feeding rack 332, the feed rods 332 and the supporting rods 323 are arranged alternately, and multiple groups of the feed rods 332 are arranged in an L shape. The discharging mechanism 34 includes a discharging rack 341 arranged on the matching plate 37, and the discharging rack 341 is provided with a discharging rod 342. The discharging rods 342 and the supporting rods 323 are arranged alternately, and multiple groups of the discharging rods 342 are arranged at an angle. Guide rollers 36 are rotatably provided on both sides of the support plate 31, and multiple groups of the guide rollers 36 are arranged at an angle, and both ends of the guide rollers 36 are provided with a baffle plate 361;

[0035] The driving mechanism 35 includes a driving sprocket 351 rotatably arranged in the roasting box 1. Four groups of driving sprockets 351 are provided, and the four groups of driving sprockets 351 are arranged in a square. One group of driving sprockets 351 can be driven by a motor. A driving chain 352 is provided between multiple groups of driving sprockets 351. A driving column 353 rotatably connected to the supporting plate 321 is provided on the driving chain 352. A connecting groove 312 for the driving column 353 to pass through is provided between the support plate 31 and the matching plate 37. Multiple groups of driving columns 353 can be provided according to production needs.

[0036] The working principle of the supporting mechanism 32 is as follows: the graphite to be roasted moves to the multiple groups of feed rods 332 arranged in an L shape through the guide rollers 36, the driving sprocket 351 drives the driving chain 352 to rotate, and the driving chain 352 drives the driving column 353 to move synchronously. Due to the sliding limit of the guide slide 311 on the guide slide 324, the driving column 353 drives the supporting plate 321 to move synchronously. The direction of the supporting plate 321 remains unchanged when the supporting plate 321 passes the feed rod 332. When the support plate 321 moves to the discharge rack 341, the limit rod 322 and the supporting rod 323 cooperate to transfer the graphite on the feed rod 332 to the supporting rod 323, so that the graphite moves synchronously with the support plate 321. When the support plate 321 passes the discharge rack 341, the limit rod 322 and the supporting rod 323 cooperate to transfer the graphite to the discharge rod 342. Since the discharge rod 342 is inclined, the graphite can move to the guide roller 36 under the action of gravity and be discharged through the discharge port 12.

[0037] Combined with attachment Figure 4 , Attachment Figure 5 , Attachment Figure 8 With attached Figure 9As shown, the feeding mechanism 4 includes a feeding connecting rod 451 rotatably arranged on the support plate 31, and a feeding gear 45 and a feeding roller 452 are respectively provided at both ends of the feeding connecting rod 451. A feeding turntable 41 is rotatably provided in the baking box 1, and a feeding groove wheel 411 is provided on the feeding turntable 41. A set of driving sprockets 351 are provided with a driving groove wheel 3511, and a feeding belt 412 is provided between the feeding groove wheel 411 and the driving groove wheel 3511. An eccentric column 415 is eccentrically provided on the feeding turntable 41, and a swing arm 42 is rotatably provided on the eccentric column 415. The swing arm 42 is provided with a swing rack 410 that meshes with the feeding gear 45. 21, a swinging rack 421 is provided with a swinging slide rail 422, a feed chute 413 is eccentrically provided on the feed turntable 41, the feed chute 413 is a rounded triangle structure, a feed slide post 414 is slidably provided in the feed chute 413, a fixed column 46 is provided in the roasting box 1, a support arm 43 rotatably connected to the feed slide post 414 is rotatably provided on the fixed column 46, a connecting arm 423 is rotatably provided at one end of the support arm 43, a swinging sleeve 424 that slides with the swinging slide rail 422 is provided on the connecting arm 423, and a limiting mechanism for intermittently limiting the feed gear 45 as the support arm 43 swings is provided on the support plate 31;

[0038] The limiting mechanism includes a limiting slide 443 arranged in the roasting box 1, a limiting slider 442 is slidably provided in the limiting slide 443, a limiting block 444 engaged with the feeding gear 45 is provided on the limiting slider 442, a limiting slide 44 is provided on the limiting slide 442, a movable slide 441 is provided on the limiting slide 44, and a support rod 431 is provided on the support arm 43 that is slidably connected to the movable slide 441.

[0039] The working principle of the feeding mechanism 4 is as follows: the driving sprocket 351 rotates, and the driving sprocket 351 drives the feeding turntable 41 to rotate synchronously through the cooperation of the driving groove wheel 3511, the feeding belt 412 and the feeding groove wheel 411. When the feeding turntable 41 rotates, the feeding chute 413 and the eccentric column 415 rotate synchronously eccentrically. Since the feeding chute 413 is eccentrically set, the feeding slide column 414 has a height difference when sliding along the feeding chute 413, thereby driving the support arm 43 to swing. When the support arm 43 swings, it drives the support rod 431 to swing synchronously. When the support rod 431 slides along the moving chute 441, it drives the limiting slide plate 44 to slide along the limiting chute 443. The limiting slider 442 slides synchronously along the limiting chute 443. The limiting slider 442 drives the limiting block 444 to slide synchronously. The gear 45 is locked when the limit block 444 moves downward and is separated from the feed gear 45. During this process, the connecting arm 423 drives the swing rack 421 to swing downward and engage with the feed gear 45 through the swing sleeve 424 and the swing rail 422. At this time, the swing rack 421 continues to move, and the swing rack 421 drives the feed roller 452 to rotate through the feed gear 45 and the feed connecting rod 451. The rotating feed roller 452 drives the graphite to move onto the feed rack. Afterwards, the limit block 444 moves upward and is engaged with the feed gear 45. The feed gear 45 is in a locked state. During this process, the connecting arm 423 drives the swing rack 421 to swing upward and separate from the feed gear 45 through the swing sleeve 424 and the swing rail 422.

[0040] Combined with attachment Figure 1 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 10 With attached Figure 11 As shown, the upper and lower ends of the roasting box 1 are respectively connected with an air inlet pipe 14 and an exhaust gas purification mechanism 2 for absorbing high-temperature dust during the roasting process. The air inlet pipe 14 is provided with an air inlet fan 141. The exhaust gas purification mechanism 2 includes a purification box 21 arranged at the upper end of the roasting box 1. The purification box 21 is connected with multiple groups of cleaning pipes 24, and the cleaning pipes 24 are provided with valves. Partition plates 22 and buffer plates 23 are sequentially provided in the purification box 21. The purification box 21 is filled with absorption liquid on both sides of the partition plate 22. A partition grid 221 is provided at the lower end of the partition plate 22, and a buffer hole 231 is provided at the upper end of the buffer plate 23. An air inlet pipe 211 and an air outlet pipe 212 are respectively connected on both sides of the purification box 21. The air inlet pipe 211 is connected to the roasting box 1, and an air outlet fan 2122 is provided on the air outlet pipe 212.

[0041] The working principle of the exhaust gas purification mechanism 2 is as follows: the air inlet fan 141 introduces the ambient air into the roasting box 1, and the air outlet fan 2122 purifies the air in the roasting box 1 through the purification box 21 and then discharges it, thereby realizing the overall gas circulation. The flowing gas will accelerate the heat exchange speed between the graphite and the roasting box 1, and improve the roasting efficiency and uniformity. The high-temperature gas in the roasting box 1 enters the purification box 21 through the air inlet pipe 211 and contacts with the absorption liquid in the purification box 21. The dust and other impurities generated during the graphite roasting process carried in the gas are absorbed by the absorption liquid, thereby realizing the purification of the gas.

[0042] Combined with attachment Figure 10 , Attachment Figure 11 , Attachment Figure 12 With attached Figure 13 As shown, an outlet filter plate 2121 is provided in the outlet pipe 212, and a cleaning mechanism 25 for cleaning the outlet filter plate 2121 is provided on the outlet filter plate 2121.

The cleaning bracket 253 is provided with a cleaning spring 254, and one end of the cleaning spring 254 is provided with a cleaning ball head 2541 that cooperates with the air outlet filter plate 2121.

[0044] The working principle of the cleaning mechanism 25: when the exhaust fan 2122 is started, the wind drives the cleaning blade 251 to rotate when passing through the exhaust pipe 212, and the cleaning blade 251 drives the cleaning bracket 253 to rotate through the cleaning rotating column 252, and the cleaning bracket 253 drives the cleaning sliding column 2551 and the cleaning brush 2552 to rotate synchronously through the cleaning sleeve 255, and the rotating cleaning brush 2552 cleans the exhaust filter plate 2121. Furthermore, during the rotation of the cleaning bracket 253, the cleaning ball head 2541 is driven to rotate through the cleaning spring 254, and the cleaning ball head 2541 drives the exhaust filter plate 2121 to vibrate slightly, thereby shaking off the dust, further avoiding the accumulation of dust on the exhaust filter plate 2121, and preventing the exhaust filter plate 2121 from being blocked.

[0045] When the present invention is implemented, the graphite to be roasted after preliminary forming enters the feed rack 331 through the feed port 11 and is placed, and the supporting plate 321 drives the limiting rod 322 and the supporting rod 323 to move along the guide slide 311. When the supporting plate 321 passes the feed rack 331, the limiting rod 322 and the supporting rod 323 cooperate to transfer the graphite on the feed rod 332 to the supporting rod 323, and the graphite moves synchronously with the movement of the supporting plate 321. Afterwards, the graphite completes the roasting operation through the preheating stage, the heating stage, the roasting stage, the cooling stage and the cooling stage in sequence. When the supporting plate 321 passes the discharging rack 341, the limiting rod 322 and the supporting rod 323 cooperate to transfer the graphite to the discharging rod 342. The roasted graphite moves to the guide roller 36 under the action of gravity and is discharged through the discharging port 12, thereby completing the roasting operation of graphite production.
