Description

Technical Field

[0001] This utility model relates to the field of graphite processing technology, specifically to a feeding structure for a dome graphite centrifuge. Background Technology

[0002] In the chemical purification of spherical graphite, the properties of graphite to resist acid and alkali and corrosion are utilized. Spherical graphite is treated with acid and alkali to dissolve impurities, which are then washed away to improve the grade of concentrate. Currently, after water washing, spherical graphite is usually dehydrated using a centrifuge driven by a main motor to remove the water contained in the pores of the spherical graphite.

[0003] Currently, when processing spherical graphite, the raw material is usually poured into the centrifuge through a feeding structure before separation. However, the traditional feeding structure does not have a mechanism to control the amount of raw material added, which can easily cause blockages due to excessive raw material, resulting in adverse effects and reduced processing efficiency of the dome graphite centrifuge. To address this issue, we provide a feeding structure for a dome graphite centrifuge that solves the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a feeding structure for a dome graphite centrifuge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding structure for a dome graphite centrifuge, including a feeding box, a connecting rod for connecting the dome graphite centrifuge is fixedly connected to the bottom surface of the feeding box, a connecting cylinder communicating with the dome graphite centrifuge is installed on the bottom surface of the feeding box, and a control valve is installed on the outer surface of the connecting cylinder, and a feeding component for preventing blockage during the conveying of the dome graphite is provided inside the feeding box.

[0006] Furthermore, the feeding assembly includes a fixed frame fixedly connected to the feeding box. A servo motor is installed on the inner wall of the fixed frame. The output shaft end of the servo motor is fixedly connected to a first rotating rod that is rotatably connected to the feeding box. A conveying cylinder is fixedly connected to the outer surface of the first rotating rod. When the servo motor is powered on and started, it can drive the conveying cylinder to rotate inside the feeding box through the first rotating rod. The groove on the conveying cylinder can hold spherical graphite and quantitatively convey the spherical graphite downwards when the conveying cylinder rotates, preventing excessive addition of spherical graphite from causing blockage.

[0007] Furthermore, the feeding assembly also includes a first sprocket fixedly connected to the first rotating rod and a second rotating rod disposed outside the feeding box. The outer surface of the second rotating rod is rotatably connected to a support block fixedly connected to the feeding box, and the outer surface of the second rotating rod is fixedly connected to the second sprocket. The first sprocket and the second sprocket are connected by chain drive. The first rotating rod can drive the first sprocket to rotate, and drive the second sprocket to rotate through the chain drive, thereby driving the second rotating rod to rotate in the inner wall of the support block.

[0008] Furthermore, the feeding assembly also includes a cam fixedly connected to the second rotating rod and a connecting frame fixedly connected to the feeding box. The inner wall of the connecting frame is slidably connected to a sliding plate and a sliding rod, and the sliding plate and the sliding rod are fixed together. A rubber head is fixedly connected to the end of the sliding rod away from the sliding plate. After the second sprocket rotates, it can squeeze the sliding plate, causing the sliding plate to slide in the inner wall of the connecting frame. The sliding plate can drive the rubber head to move through the sliding rod, causing it to knock on the outside of the feeding box, so that the spherical graphite slides down quickly, thereby avoiding the blockage of the spherical graphite during the conveying process.

[0009] Furthermore, a third rotating rod is rotatably connected to the inner wall of the feed box. A stirring rod and a third sprocket are fixedly connected to the outer surface of the third rotating rod. A fourth sprocket is fixedly connected to the outer surface of the first rotating rod. The third sprocket and the fourth sprocket are connected by a chain drive. The first rotating rod can drive the fourth sprocket to rotate. The fourth sprocket can drive the third sprocket to rotate through the chain. In turn, the stirring rod is driven to rotate through the third rotating rod, thereby stirring and mixing the spherical graphite and the reagent to fully dissolve the internal impurities and improve the purity of the spherical graphite.

[0010] Furthermore, the inner wall of the feed box is inlaid with a first bearing and a sealed bearing. The inner rings of the first bearing and the sealed bearing are fixedly connected to the outer surfaces of the first rotating rod and the third rotating rod, respectively. By setting the first bearing and the second bearing, the first rotating rod and the second rotating rod can be made more stable when rotating, and the resistance of the first rotating rod and the second rotating rod when rotating can be reduced, thereby avoiding jamming and swaying of the first rotating rod and the second rotating rod during use.

[0011] Furthermore, a second bearing is embedded in the inner wall of the support block. The inner ring of the second bearing is fixedly connected to the outer surface of the second rotating rod. By setting the second bearing, the second rotating rod can be made more stable when rotating and the resistance of the second rotating rod when rotating can be reduced, thereby avoiding jamming and swaying of the second rotating rod during use.

[0012] Furthermore, a liquid storage tank is fixedly connected to one side of the feed box, and a pump body is installed on the upper surface of the liquid storage tank. The input end of the pump body passes through the liquid storage tank and extends into the interior of the liquid storage tank. The output end of the pump body is connected to a connecting pipe, and the connecting pipe is connected to the feed box. The liquid storage tank contains acidic or alkaline agents for treating spherical graphite. When the pump body is powered on and started, it can generate suction, so that the acidic or alkaline agents pass through the input end, output end and connecting pipe of the pump body in sequence until they enter the feed box to treat the spherical graphite.

[0013] Compared with existing technologies, the feeding structure of this dome graphite centrifuge has the following advantages:

[0014] 1. This utility model enables the feeding structure to add raw materials into the dome graphite centrifuge for processing spherical graphite before separation. The feeding structure is equipped with a feeding component to allow for the addition of appropriate amounts of raw materials. At the same time, the conveying pipe can be reciprocated to prevent blockage of the raw materials during the conveying process, thereby ensuring the processing efficiency of the dome graphite centrifuge.

[0015] 2. This utility model, by setting up a first bearing and a second bearing, makes the first and second rotating rods more stable during rotation and reduces their resistance, thereby preventing jamming and wobbling of the first and second rotating rods during use. By setting up a sealed bearing, the third rotating rod is made more stable during rotation and its resistance is reduced, thus preventing jamming and wobbling of the third rotating rod during use. At the same time, the connection between the third rotating rod and the feed box can be sealed to prevent liquid leakage. By setting up a liquid storage tank, pump body and connecting pipe, acidic or alkaline agents can be added to treat spherical graphite. Through the cooperation between the third rotating rod, stirring rod, third sprocket and fourth sprocket, the spherical graphite and treatment agent entering the feed box are stirred, so that the internal impurities are fully dissolved, thereby improving the purity of the spherical graphite.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] As described in the background section, traditional feeding structures do not have a structure to control the amount of raw materials added, which can easily cause blockages in the feeding structure due to excessive raw materials, resulting in adverse effects and reducing the processing efficiency of the dome graphite centrifuge. Therefore, this embodiment provides a feeding structure for a dome graphite centrifuge.

[0025] See Figures 1 to 6 This embodiment proposes a feeding structure for a dome graphite centrifuge, including a feeding box 1. A connecting rod 2 for connecting the dome graphite centrifuge is fixedly connected to the bottom surface of the feeding box 1. A connecting cylinder 3 that communicates with the dome graphite centrifuge is installed on the bottom surface of the feeding box 1, and a control valve is installed on the outer surface of the connecting cylinder 3.

[0026] The feed box 1 can be connected to the dome graphite centrifuge via the connecting rod 2. At the same time, the connecting cylinder 3 is connected to the top of the dome graphite centrifuge. By opening the control valve on the connecting cylinder 3, the impurity-removed spherical graphite can be discharged into the dome graphite centrifuge for centrifugation.

[0027] The feed box 1 is equipped with a feed assembly to prevent blockage during the conveying of dome graphite. The feed assembly includes a fixed frame 401 fixedly connected to the feed box 1. A servo motor 402 is installed on the inner wall of the fixed frame 401. The output shaft end of the servo motor 402 is fixedly connected to a first rotating rod 403 rotatably connected to the feed box 1. A conveying cylinder 404 is fixedly connected to the outer surface of the first rotating rod 403.

[0028] When the servo motor 402 is powered on and started, it can drive the conveying cylinder 404 to rotate inside the feed box 1 through the first rotating rod 403. The groove on the conveying cylinder 404 can hold spherical graphite and quantitatively convey the spherical graphite downwards when the conveying cylinder 404 rotates, preventing excessive addition of spherical graphite from causing blockage. The groove on the conveying cylinder 404 is symmetrically arranged.

[0029] The feeding assembly also includes a first sprocket 405 fixedly connected to the first rotating rod 403 and a second rotating rod 406 disposed outside the feeding box 1. The outer surface of the second rotating rod 406 is rotatably connected to a support block 407 fixedly connected to the feeding box 1. The outer surface of the second rotating rod 406 is fixedly connected to a second sprocket 408, and the first sprocket 405 and the second sprocket 408 are connected by chain drive.

[0030] The first rotating rod 403 can drive the first sprocket 405 to rotate, and through the chain transmission, drive the second sprocket 408 to rotate, thereby driving the second rotating rod 406 to rotate in the inner wall of the support block 407.

[0031] The inner wall of the support block 407 is inlaid with a second bearing 10. The inner ring of the second bearing 10 is fixedly connected to the outer surface of the second rotating rod 406. By setting the second bearing 10, the second rotating rod 406 can be made more stable when rotating and the resistance of the second rotating rod 406 when rotating can be reduced, thereby avoiding jamming and swaying of the second rotating rod 406 during use.

[0032] The feeding assembly also includes a cam 409 fixedly connected to the second rotating rod 406 and a connecting frame 4010 fixedly connected to the feeding box 1. The inner wall of the connecting frame 4010 is slidably connected to a slide plate 4011 and a slide rod 4012, and the slide plate 4011 and the slide rod 4012 are fixed together. A rubber head 4013 is fixedly connected to the end of the slide rod 4012 away from the slide plate 4011.

[0033] After the second sprocket 408 rotates, it can squeeze the slide plate 4011, causing the slide plate 4011 to slide in the inner wall of the connecting frame 4010. The slide plate 4011 can drive the rubber head 4013 to move through the slide rod 4012, so that it can knock on the outside of the feed box 1, causing the spherical graphite to slide down quickly, thereby avoiding the blockage of the spherical graphite during the conveying process. The setting of the rubber head 4013 can avoid excessive damage to the feed box 1 when knocking.

[0034] A liquid storage tank 12 is fixedly connected to one side of the feed box 1. A pump body 13 is installed on the upper surface of the liquid storage tank 12. The input end of the pump body 13 passes through the liquid storage tank 12 and extends into the interior of the liquid storage tank 12. The output end of the pump body 13 is connected to a connecting pipe 14, and the connecting pipe 14 is connected to the feed box 1.

[0035] The storage tank 12 contains acidic or alkaline agents for processing spherical graphite. When the pump body 13 is powered on and started, it generates suction, which allows the acidic or alkaline agents to pass sequentially through the input end, output end and connecting pipe 14 of the pump body 13 until they enter the feed box 1 to process the spherical graphite.

[0036] The inner wall of the feed box 1 is rotatably connected to a third rotating rod 5. The outer surface of the third rotating rod 5 is fixedly connected to a stirring rod 6 and a third sprocket 7. The outer surface of the first rotating rod 403 is fixedly connected to a fourth sprocket 8, and the third sprocket 7 and the fourth sprocket 8 are connected by a chain drive.

[0037] The first rotating rod 403 can drive the fourth sprocket 8 to rotate. The fourth sprocket 8 can drive the third sprocket 7 to rotate via a chain, which in turn drives the stirring rod 6 to rotate via the third rotating rod 5, thereby stirring and mixing the spherical graphite with the reagent, so that the internal impurities are fully dissolved, in order to improve the purity of the spherical graphite.

[0038] The inner wall of the feed box 1 is inlaid with a first bearing 9 and a sealed bearing 11. The inner rings of the first bearing 9 and the sealed bearing 11 are fixedly connected to the outer surfaces of the first rotating rod 403 and the third rotating rod 5, respectively.

[0039] By setting the first bearing 9 and the sealed bearing 11, the first rotating rod 403 and the third rotating rod 5 can be made more stable when rotating, and the resistance of the first rotating rod 403 and the third rotating rod 5 when rotating can be reduced, thereby avoiding jamming and swaying of the first rotating rod 403 and the third rotating rod 5 during use. At the same time, the sealed bearing 11 can seal the connection between the third rotating rod 5 and the feed box 1 to prevent liquid leakage.

[0040] The components in the accompanying drawings of this utility model are for styling reference only and are not specific dimensional standards. The specific dimensions are determined according to the actual production requirements, and the materials of each component can be replaced accordingly based on actual needs.

[0041] Working principle: The feed box 1 is fixed to the top of the dome graphite centrifuge using the connecting rod 2. Simultaneously, the connecting cylinder 3 is connected to the top of the dome graphite centrifuge. Then, the servo motor 402 is powered on and started. Spherical graphite is then poured into the feed box 1. The servo motor 402 drives the first rotating rod 403 to rotate, which in turn drives the conveying cylinder 404 to rotate inside the feed box 1. The grooves on the conveying cylinder 404 hold the spherical graphite as it rotates. During operation, spherical graphite is quantitatively conveyed downwards. Simultaneously, the first rotating rod 403 drives the first sprocket 405 to rotate, which in turn drives the second sprocket 408 to rotate via chain transmission. This, in turn, drives the second rotating rod 406 to rotate within the inner wall of the support block 407. After the second sprocket 408 rotates, it can compress the slide plate 4011, causing the slide plate 4011 to slide within the inner wall of the connecting frame 4010. The slide plate 4011 can drive the rubber head 4013 to move via the slide rod 4012, allowing it to feed material into the outside of the feed box 1. After the first tapping, the second sprocket 408 rotates until it disengages from the slide plate 4011. Under gravity, the rubber head 4013 slides down away from the feed box 1. This process is repeated to tap the feed box 1 repeatedly, causing the spherical graphite to gradually move downwards, preventing blockage during transport. Then, the pump body 13 is powered on and started, generating suction to allow the acidic or alkaline reagent to pass sequentially through the pump body 13's input end, output end, and connecting pipe 14. Until the spherical graphite enters the feed box 1 for processing, the first rotating rod 403 can drive the fourth sprocket 8 to rotate, the fourth sprocket 8 can drive the third sprocket 7 to rotate through the chain, and then drive the stirring rod 6 to rotate through the third rotating rod 5, thereby stirring and mixing the spherical graphite with the reagent, so that the internal impurities are fully dissolved, so as to improve the purity of the spherical graphite. After the processing is completed, the control valve on the connecting cylinder 3 is opened, so that the impurity-removed spherical graphite can be discharged into the dome graphite centrifuge for centrifugation.
