Abstract
Description
Technical Field
[0001] This utility model relates to the field of spherical graphite grading technology, specifically to a spherical graphite grader. Background Technology
[0002] Spherical graphite is a high-performance material with wide applications in various fields. It is primarily used in the manufacture of anode materials for lithium-ion batteries, significantly improving battery energy density and cycle performance. Furthermore, spherical graphite can be used as a conductive filler in conductive coatings, enhancing the coating's conductivity. In the lubricant field, it reduces friction and wear. Simultaneously, it is an important component of high-end sealing materials, improving sealing performance. These applications of spherical graphite are all attributed to its unique physical and chemical properties.
[0003] Existing spherical graphite classifiers generally employ cyclone separation technology. However, due to the physical characteristics of spherical graphite, such as irregular particle shape and tendency to agglomerate, the conveying pipes are prone to clogging during the classification process. Once a blockage occurs, the entire conveying system must be stopped immediately for cleaning and maintenance, significantly reducing the operating efficiency of the production line. To address this issue, we propose a novel spherical graphite classifier. Utility Model Content
[0004] The purpose of this invention is to provide a spherical graphite classifier to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Spherical graphite classifier, including:
[0007] A cylindrical body with a discharge hole extending through it, and a first connecting pipe fixedly connected to the outside of the cylindrical body, the first connecting pipe communicating with the discharge hole;
[0008] A feeding pipe is fixedly connected to the top of the cylinder, and the bottom end of the feeding pipe extends into the cylinder.
[0009] A feeding pipe is fixedly connected to the bottom of the cylinder.
[0010] A feeding assembly is installed inside the cylinder and is capable of conveying graphite into the cylinder.
[0011] Preferably, the feeding assembly includes:
[0012] The motor is fixedly connected to the outside of the cylinder, and a worm gear is fixedly connected to the drive end of the motor;
[0013] A worm gear is rotatably connected to the wall of the cylinder, and the worm meshes with the worm gear.
[0014] An internal gear, which is fixedly connected to the top of the worm gear;
[0015] Driven gear, the driven gear is rotatably connected to the inner side of the cylinder, and the driven gear meshes with the internal gear;
[0016] An air inlet is fixedly connected to the top of the driven gear. One end of the air inlet is fixedly connected to a flexible hose, which extends out of the cylinder and is fixedly connected to a second connecting pipe.
[0017] The first sealing plate is fixedly connected to the top of the internal gear, and the first sealing plate automatically seals the discharge hole.
[0018] Preferably, a valve head is fixedly provided at the bottom end of the feeding pipe, and the feeding pipe is detachable from the cylinder.
[0019] Preferably, a discharge pipe is fixedly connected to the inner bottom of the cylinder.
[0020] Preferably, a box body is fixedly connected to the outside of the cylinder, and a hydraulic rod is fixedly connected to the outside of the box body.

[0021] Preferably, the feed pipe is detachable from the bottom of the cylinder.
[0022] Preferably, a position sensor is fixedly connected inside the box.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] 1. By setting up a feeding assembly, when the feeding pipe or the unloading pipe is blocked, the motor is started. The motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel synchronously drives the internal gear to rotate, which in turn drives the driven gear to rotate. The driven gear drives the air inlet head to rotate, turning the air inlet head from being biased towards the inner wall of the cylinder to pointing towards the central axis of the cylinder. At this time, it is exactly aligned with the discharge hole. Then the air speed is increased, and the airflow containing spherical graphite is directly delivered to the discharge hole. Then, it is delivered to the cylinder of another device in parallel through the discharge hole and the first connecting pipe, where it is graded, thus achieving uninterrupted operation.
[0025] 2. When the angle of the air inlet is smaller relative to the inner wall of the cylinder, it generates a greater initial rotational velocity upon entering the separation zone. This acceleration effect causes the material to experience stronger shear and centrifugal forces during separation, resulting in finer separated particles. Conversely, if the angle of the air inlet is larger, the initial rotational velocity of the material entering the separation zone will decrease accordingly, weakening the shear and centrifugal forces and resulting in relatively larger separated particles. Therefore, by finely adjusting the angle of the air inlet, the size of the separated particles can be effectively controlled to meet different production needs. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] like Figure 1-5As shown, in this embodiment, the spherical graphite classifier includes a cylinder 1, a feeding pipe 2, a discharging pipe 3, and a feeding assembly 4. A discharge hole 11 is provided through the inside of the cylinder 1, and a first connecting pipe 12 is fixedly connected to the outside of the cylinder 1, communicating with the discharge hole 11. The feeding pipe 2 is fixedly connected to the top of the cylinder 1, and the bottom end of the feeding pipe 2 extends into the cylinder 1. The discharging pipe 3 is fixedly connected to the bottom of the cylinder 1.
[0034] The feeding assembly 4 includes a motor 41, a worm gear 42, an internal gear 43, a driven gear 44, an air inlet head 45, and a first sealing plate 46. The motor 41 is fixedly connected to the outside of the cylinder 1, and a worm 411 is fixedly connected to the drive end of the motor 41. The worm gear 42 is rotatably connected to the wall of the cylinder 1, and the worm 411 meshes with the worm gear 42. The internal gear 43 is fixedly connected to the top of the worm gear 42. The driven gear 44 is rotatably connected to the inside of the cylinder 1, and the driven gear 44 meshes with the internal gear 43. The air inlet head 45 is fixedly connected to the top of the driven gear 44, and a hose 4 is fixedly connected to one end of the air inlet head 45. 51. The hose 451 extends out of the cylinder 1 and is fixedly connected to the second connecting pipe 452; the first sealing plate 46 is fixedly connected to the top of the internal gear 43, and the first sealing plate 46 seals the discharge hole 11 accordingly; it should be noted that the bottom of the worm gear 42 is rotatably connected to the wall of the cylinder 1, and both the worm gear 42 and the internal gear 43 are set inside the wall of the cylinder 1 without interference. Similarly, the driven gear 44 is rotatably connected to the inside of the wall of the cylinder 1 without interference. At the same time, since it is not exposed, it can avoid graphite from entering and causing jamming. In addition, by setting the hose 451, it can adapt to the rotation of the air inlet 45.
[0035] In this embodiment, a valve head 5 is fixedly installed at the bottom of the feeding pipe 2; a discharge pipe 6 is fixedly connected to the inner bottom of the cylinder 1; a box 7 is fixedly connected to the outside of the cylinder 1, and a hydraulic rod 8 is fixedly connected to the outer side of the box 7. The driving end of the hydraulic rod 8 passes through the box 7 and the cylinder 1 and is fixedly connected to a second sealing plate 81. The second sealing plate 81 is slidably engaged inside the cylinder 1 and seals the bottom of the discharge pipe 6 accordingly. A position sensor 9 is fixedly connected inside the box 7. While the air inlet head 45 is rotating, the hydraulic rod 8 is manually activated to drive the second sealing plate 81 to seal the discharge pipe 6. The position sensor 9 senses the movement of the driving end of the hydraulic rod 8 and controls the valve head 5 to seal the bottom of the feeding pipe 2. This seals the upper and lower channels, making it convenient to directly deliver the airflow to the discharge hole 11. It should be noted that the position sensor 9 is existing technology and will not be described in detail.
[0036] In addition, it is necessary to increase the air speed to prevent the air speed from slowing down due to the increased distance during the process of conveying to another device. At the same time, increasing the air speed can prevent spherical graphite in the airflow from falling into the discharge pipe 6, and can directly convey the airflow to another device.
[0037] Specifically, when the feed pipe 2 or the discharge pipe 3 is blocked, the motor 41 is started. The motor 41 drives the worm gear 411 to rotate, which in turn drives the worm wheel 42 to rotate. The worm wheel 42 synchronously drives the internal gear 43 to rotate. The rotation of the internal gear 43 drives the driven gear 44 to rotate. The driven gear 44 drives the air inlet head 45 to rotate, turning the air inlet head 45 from being biased towards the inner wall of the cylinder 1 to pointing towards the central axis of the cylinder 1. At this time, it is exactly aligned with the discharge hole 11. Then the air speed is increased, and the airflow containing spherical graphite is directly delivered to the discharge hole 11. Then, it is delivered to the cylinder 1 of another device connected in parallel through the discharge hole 11 and the first connecting pipe 12. In the other device, it is graded, realizing uninterrupted operation.
[0038] Furthermore, the feeding pipe 2 is detachable from the cylinder 1; the discharging pipe 3 is detachable from the bottom of the cylinder 1. After the upper and lower channels are closed, the feeding pipe 2 and the discharging pipe 3 can be disassembled for cleaning.
[0039] Furthermore, when the angle of the air inlet 45 is relatively small relative to the inner wall of the cylinder 1, it generates a larger initial rotational velocity upon entering the separation zone. This acceleration effect causes the material to experience stronger shear and centrifugal forces during the separation process, resulting in finer separated particles. Conversely, if the angle of the air inlet 45 is larger, the initial rotational velocity of the material entering the separation zone will decrease accordingly, weakening the shear and centrifugal forces and resulting in relatively larger separated particles. Therefore, by finely adjusting the angle of the air inlet 45, the size of the separated particles can be effectively controlled to meet different production needs.
[0040] Working Principle: It should be noted that this device can be connected in parallel in two or more sets via the first connecting pipe 12 and the second connecting pipe 452. Specifically, firstly, airflow containing spherical graphite is introduced into the cylinder 1 through the second connecting pipe 452, the flexible hose 451, and the air inlet 45. At this time, the angle of the air inlet 45 is deflected towards the inner wall of the cylinder 1, forming a rotating airflow. Then, the smaller particles of spherical graphite are transported to the feeding pipe 2 by the rotating airflow and discharged through the feeding pipe 2. Larger spherical graphite particles are discharged through the discharge pipe 3. When the feeding pipe 2 or the discharge pipe 3 is blocked, the motor 41 is started. Motor 41 drives worm gear 411 to rotate, which in turn drives worm wheel 42 to rotate. Worm wheel 42 synchronously drives internal gear 43 to rotate. Internal gear 43 rotates and drives driven gear 44 to rotate. Driven gear 44 drives air inlet head 45 to rotate, turning air inlet head 45 from being biased towards the inner wall of cylinder 1 to pointing towards the central axis of cylinder 1. At this time, it is exactly aligned with the discharge hole 11. Then the air speed is increased, and the airflow containing spherical graphite is directly delivered to the discharge hole 11. Then, it is delivered through discharge hole 11 and first connecting pipe 12 to the cylinder 1 of another device connected in parallel, where it is graded, realizing uninterrupted operation.
