Spherical graphite classifier

Abstract

This utility model provides a spherical graphite classifier, including a gyratory screen body, a buffer platform, and a classification chamber. A dust cover is fixedly connected to the top of the classification chamber, a feed pipe is fixedly connected to the top of the dust cover, and a feeding hopper is fixedly connected to the top of the feed pipe. A dispersion cover is fixedly connected to the inner wall of the classification chamber, a material inlet is provided on the outer wall of the dispersion cover, a through groove is provided on the top of the dispersion cover, and a spring is fixedly connected to the inner wall of the dispersion cover. Through the dispersion cover, material inlet, spring, lifting rod, and buffer platform, the spherical graphite first impacts the buffer platform. The spring force provides a buffering effect, dispersing the spherical graphite on the surface of the dispersion cover. Finally, it enters the screen at the bottom of the classification chamber through the material inlet. This prevents the weight of the spherical graphite from directly impacting the screen area below the feeding hopper during feeding, thus extending the service life of the device.

Description

Technical Field

[0001] This utility model is a spherical graphite classifier, belonging to the field of graphite processing equipment. Background Technology

[0002] Spherical graphite is produced by using high-quality, high-carbon natural flake graphite as raw material and advanced processing technology to modify the graphite surface. It produces graphite products of different fineness and elliptical spherical shapes. The diameters of the spherical graphite particles vary, so a spherical graphite classifier is used to separate them into different sizes. The principle of the spherical graphite classifier is mostly driven by a common motor to simulate the motion of manual screening. This causes the material to form a three-dimensional rolling motion of horizontal and tossing on the screen. Small-diameter spherical graphite particles fall to the bottom layer through the gaps in the screen, while large-diameter spherical graphite particles are isolated, thus achieving efficient screening.

[0003] However, most existing spherical graphite classifiers on the market currently use a classification chamber with a screen on the inner wall and a feed hopper at the top. Spherical graphite enters the classification chamber from the funnel-shaped feed pipe and falls onto the screen for screening. When a large amount of spherical graphite is poured directly into the classification chamber from the feed hopper, the impact force of the graphite will directly hit the screen area located below the feed hopper. As a result, the area of ​​the screen below the feed hopper will be damaged due to long-term impact, which greatly reduces the service life of the device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spherical graphite classifier to solve the problems mentioned in the background art. When feeding spherical graphite, the gravity of the graphite will not directly impact the screen area located below the feed hopper, thus extending the service life of the device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a spherical graphite classifier, comprising a gyratory screen body, a buffer platform, and a classification chamber. A dust cover is fixedly connected to the top of the classification chamber, a feed pipe is fixedly connected to the top of the dust cover, a feeding hopper is fixedly connected to the top of the feed pipe, a dispersion cover is fixedly connected to the inner wall of the classification chamber, a material inlet is provided on the outer wall of the dispersion cover, a through groove is provided on the top of the dispersion cover, a spring is fixedly connected to the inner wall of the dispersion cover, a connecting plate is fixedly connected to the bottom of the spring, and a lifting rod is fixedly connected to the top of the connecting plate.

[0006] Furthermore, a centrifugal air compressor is fixedly connected to the outer wall of the dust cover, and the air outlet pipe of the centrifugal air compressor is fixedly connected to the feed pipe. The centrifugal air compressor is a mature device that is already available on the market and is an existing device, so it will not be explained in detail here. The operation of the centrifugal air compressor will compress the external air and then deliver it to the inside of the feed pipe through the air outlet pipe on the centrifugal air compressor.

[0007] Furthermore, the inner wall of the feeding hopper is provided with a ventilation channel, and the ventilation channel is connected to the feeding pipe. The airflow inside the feeding pipe is transported to the interior of the ventilation channel and blown out through the ventilation channel.

[0008] Furthermore, the inner wall of the ventilation duct is curved, and the outer wall of the grading chamber is fixedly connected to the discharge pipe. Since both the ventilation duct and the inner wall of the feeding hopper are curved, the airflow will blow into the inside of the feeding hopper along the ventilation duct. The atmospheric pressure will cause the top of the feeding hopper to have a downward suction force. Therefore, when feeding, the flying toner will be sucked into the inside of the grading chamber, avoiding the situation of toner flying during feeding.

[0009] Furthermore, the lifting rod is slidably sleeved with the spring, and the lifting rod is slidably sleeved with the through groove. The buffer platform will move downward under gravity. The elastic force of the spring can make the buffer platform play a certain buffering effect on the spherical graphite, and the spherical graphite will be dispersed on the surface of the dispersion cover.

[0010] Furthermore, a screw is fixedly connected to the top of the lifting rod, and the screw is threadedly connected to the buffer platform. A threaded groove is provided at the bottom of the buffer platform, and the buffer platform can be threadedly connected to the screw through the threaded groove. Thus, when the buffer platform is worn out after a long period of use, it can be rotated to disassemble and replace it, further extending the service life of the device.

[0011] The beneficial effects of this utility model are: 1. Through the setting of the dispersion hood, feed inlet, spring, lifting rod and buffer platform, when spherical graphite enters the classification chamber through the feed pipe, it will first hit the buffer platform. The buffer platform will move downward under gravity. The elastic force of the spring can make the buffer platform have a certain buffering effect on the spherical graphite. The spherical graphite will be dispersed on the surface of the dispersion hood. Finally, it will enter the screen at the bottom of the classification chamber through the feed inlet. In this way, the gravity of the spherical graphite will not directly hit the screen area below the feed hopper when feeding, thus extending the service life of the device.

[0012] 2. Through the installation of the feeding hopper, ventilation duct, and centrifugal air compressor, the operation of the centrifugal air compressor compresses and delivers air into the ventilation duct. The airflow then blows along the ventilation duct into the feeding hopper, creating a downward suction force at the top of the feeding hopper. As a result, during feeding, flying toner is sucked into the classification chamber, preventing toner from flying around and polluting the surrounding working environment. This further meets the working requirements of the device and is therefore worthy of promotion. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a spherical graphite classifier, including a gyratory screen body 1, a buffer platform 15, and classification chambers 16. The gyratory screen body 1 is a screening device already available on the market, model "YBS-800". Multiple classification chambers 16 are included. The operation of the gyratory screen body 1 causes multiple classification chambers 16 to vibrate. The inner walls of each classification chamber 16 are equipped with screens with decreasing gaps. The gyratory screen body 1 causes the material to undergo a three-dimensional tumbling motion of horizontal and tossing motion on the screens. Small-diameter spherical graphite falls through the screen gaps to the bottom layer, while large-diameter spherical graphite is isolated, thus achieving the screening of spherical graphite inside the classification chambers 16. A dust cover 3 is fixedly connected to the top of the grading chamber 16. The dust cover 3 can prevent the graphite powder in the graphite from flying during the screening process. A feed pipe 4 is fixedly connected to the top of the dust cover 3. A feeding hopper 5 is fixedly connected to the top of the feed pipe 4. Spherical graphite can be fed through the feeding hopper 5. A dispersion cover 8 is fixedly connected to the inner wall of the grading chamber 16. A material passage 9 is opened on the outer wall of the dispersion cover 8. The diameter of the material passage 9 is large, so that spherical graphite will not be isolated on the top of the dispersion cover 8. A through groove 10 is opened on the top of the dispersion cover 8. A spring 11 is fixedly connected to the inner wall of the dispersion cover 8. A connecting plate 12 is fixedly connected to the bottom of the spring 11. A lifting rod 13 is fixedly connected to the top of the connecting plate 12.

[0016] A centrifugal air compressor 7 is fixedly connected to the outer wall of the dust cover 3, and the air outlet pipe of the centrifugal air compressor 7 is fixedly connected to the feed pipe 4. The centrifugal air compressor 7 is a mature device on the market and is an existing device, so it will not be explained in detail here. The operation of the centrifugal air compressor 7 will compress the external air and then deliver it to the inside of the feed pipe 4 through the air outlet pipe on the centrifugal air compressor 7.

[0017] The inner wall of the feeding hopper 5 is provided with a ventilation channel 6, and the ventilation channel 6 is connected to the feeding pipe 4. The airflow inside the feeding pipe 4 will be transported to the interior of the ventilation channel 6 and blown out through the ventilation channel 6.

[0018] The inner wall of the ventilation duct 6 is curved, and the outer wall of the grading chamber 16 is fixedly connected to the discharge pipe 2. Both the inner walls of the ventilation duct 6 and the feeding hopper 5 are curved, so the airflow will blow into the inside of the feeding hopper 5 along the ventilation duct 6. The atmospheric pressure will cause the top of the feeding hopper 5 to have a downward suction force. Therefore, when feeding, the flying toner will be sucked into the inside of the grading chamber 16, thus avoiding the situation of toner flying during feeding.

[0019] The lifting rod 13 is slidably sleeved with the spring 11, and the lifting rod 13 is slidably sleeved with the through groove 10. The buffer platform 15 will move downward under gravity. The elastic force of the spring 11 can make the buffer platform 15 play a certain buffering effect on the spherical graphite, and the spherical graphite will be dispersed on the surface of the dispersion cover 8.

[0020] The top of the lifting rod 13 is fixedly connected to a screw rod 14, and the screw rod 14 is threadedly connected to the buffer platform 15. The bottom of the buffer platform 15 is provided with a screw groove. The buffer platform 15 can be threadedly connected to the screw rod 14 through the screw groove. Therefore, when the buffer platform 15 is worn out after a long period of use, the buffer platform 15 can be rotated to disassemble and replace it, further extending the service life of the device.

[0021] Working principle: Step 1, the operation of the centrifugal air compressor 7 will compress and deliver air into the ventilation duct 6, and then the airflow will blow into the upper hopper 5 along the ventilation duct 6, so that the top of the upper hopper 5 has a downward suction force, and then during feeding, the flying toner will be sucked into the classification chamber 16, thus preventing the toner from flying during feeding. In step two, when the spherical graphite enters the classifying chamber 16 through the feed pipe 4, it will first hit the buffer platform 15. The buffer platform 15 will move downward under gravity. The elastic force of the spring 11 can make the buffer platform 15 have a certain buffering effect on the spherical graphite. The spherical graphite will be dispersed on the surface of the dispersion hood 8, and finally enter the screen at the bottom of the classifying chamber 16 through the feed port 9. This ensures that the gravity of the spherical graphite will not directly hit the screen area below the feed hopper when it is fed, thus extending the service life of the device.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
