Description

Technical Field

[0001] This utility model relates to the field of grading device technology, and in particular to a grading device for deep processing of petroleum coke. Background Technology

[0002] Petroleum coke is a solid carbonaceous material produced during petroleum refining, primarily obtained through processes such as thermal cracking, heating, or catalytic cracking of heavy crude oil or petroleum fractions. It is typically black or dark brown, with high carbon content and low volatility, and is insoluble in water. Petroleum coke is widely used in industries such as batteries, electrolytic aluminum, carbon materials, and steelmaking as an important raw material. Its properties, such as electrical conductivity, high-temperature resistance, and chemical stability, are the reasons for its widespread selection in these applications.

[0003] After petroleum coke production, particles of varying sizes are produced. These particles need to be sieved during packaging, requiring a grading device for effective size separation. Currently, existing petroleum coke grading devices lack a structure designed to collect dust particles, resulting in dust adhering to the surface of larger pieces of petroleum coke and failing to achieve ideal fine separation and collection. This can lead to a waste of petroleum coke powder resources and cause operational inconvenience during the petroleum coke fine separation process.

[0004] Based on this, we propose a grading device for deep processing of petroleum coke to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a grading device for deep processing of petroleum coke, which can solve the problems of waste of petroleum coke powder resources and inconvenience of operation caused by the lack of powder and dust collection devices in existing petroleum coke grading devices.

[0007] To solve the above technical problems, this utility model provides a grading device for deep processing of petroleum coke, which adopts the following technical solution: it includes a metal frame, a grading and screening component is installed in the middle of the metal frame, a negative pressure extractor is connected to one side of the grading and screening component, an extraction port of the negative pressure extractor is connected to an extraction pipe, and a connecting flange is connected to the discharge port of the negative pressure extractor.

[0008] A drive motor is installed on one side of the bottom of the metal frame. The drive motor and the output end of the negative pressure extractor are both connected to a first transmission wheel. A mechanical vibrator is installed in the middle of the metal frame. The output end of the mechanical vibrator is connected to a second transmission wheel. A transmission belt is connected between the second transmission wheel and the two sets of first transmission wheels. A transmission rod is also provided between the mechanical vibrator and the bottom of the grading and screening assembly.

[0009] Optionally, the grading and screening assembly includes a screening plate frame, the screening plate frame is internally connected to a grading and screening component, and a feeding hopper is also provided at one end of the screening plate frame.

[0010] Optionally, a baffle plate is installed at the bottom of the screening plate frame, and a first discharge hopper is provided at one end of the baffle plate. A first mounting groove is opened around the inner side of the screening plate frame near the baffle plate, and a second discharge hopper is connected to the end of the first mounting groove near the first discharge hopper.

[0011] Optionally, a second mounting groove is provided around the inner perimeter of the screening plate frame near the opening, and a third hopper is connected to one end of the second mounting groove near the second discharge hopper.

[0012] Optionally, the grading and screening component includes a first filter screen plate, which is installed inside a first mounting groove, and a second filter screen plate is provided on top of the first filter screen plate, which is connected inside a second mounting groove.

[0013] Optionally, the aperture of the second filter screen is larger than that of the first filter screen, the first filter screen and the second discharge hopper are on the same horizontal plane, and the second filter screen and the third discharge hopper are on the same horizontal plane.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. This solution adds a negative pressure extractor to one side of the grading and screening assembly. Under the combined action of the drive motor, the first transmission wheel, the mechanical vibrator, the second transmission wheel, the transmission belt, and the transmission rod, the negative pressure extractor not only provides vibration force to the screening plate frame installed in the middle of the metal frame, but also operates synchronously. When the petroleum coke particles to be processed flow into the screening plate frame from the opening at the bottom of the feeding hopper under the action of the mechanical vibrator, the petroleum coke particles discharged by vibration can be vacuumed through the extraction port of the negative pressure extractor and the connected extraction pipe. The extraction port of the extraction pipe is located next to the opening of the feeding hopper, which effectively sucks the powder on the surface of the petroleum coke particles into the negative pressure extractor and discharges it outward through its discharge port and connecting flange. By connecting a collection container to the connecting flange, the petroleum coke powder can be conveniently collected.

[0016] 2. The grading and screening component in this solution mainly consists of a screening plate frame, grading and screening parts, and a feeding hopper. The grading and screening parts include a first filter screen and a second filter screen with a larger aperture than the first filter screen. When the screening plate frame vibrates violently under the drive of a mechanical vibrator, petroleum coke particles are discharged from the feeding hopper and roll along the inclination of the screening plate frame. When the particle size is smaller than the aperture of the second filter screen, they can pass through the screen and fall onto the first filter screen. Particles that do not pass through are discharged through the third discharge hopper. Particles that fall onto the surface of the first filter screen can undergo secondary screening. When the particle size is smaller than the aperture of the first filter screen, they will pass through the first filter screen and fall onto the baffle plate, and be discharged through the first discharge hopper at one end of the baffle plate. Particles that do not pass through are discharged through the second discharge hopper.

[0017] 3. As can be seen from the above, the petroleum coke grading device designed in this scheme realizes the synchronous drive of the negative pressure extractor and the mechanical vibrator through a set of drive motors. When the negative pressure extractor and the mechanical vibrator are running at the same time, it can not only perform fine screening of the petroleum coke particles to be processed, but also extract and collect the petroleum coke powder adhering to the surface of the petroleum coke particles. This avoids the waste of petroleum coke powder resources and also prevents the petroleum coke powder from generating dust in the rolling state. Attached Figure Description

[0024] 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.

[0025] Example: Refer to Figures 1 to 4 This utility model provides an embodiment of a grading device for deep processing of petroleum coke, comprising a metal frame 1, a grading and screening component 2 installed in the middle of the metal frame 1, a negative pressure extractor 3 connected to one side of the grading and screening component 2, an extraction pipe 4 connected to the extraction port of the negative pressure extractor 3, a connecting flange 5 connected to the discharge port of the negative pressure extractor 3, a drive motor 6 installed on one side of the bottom of the metal frame 1, and a first transmission wheel 7 connected to both the output end of the drive motor 6 and the negative pressure extractor 3, a mechanical vibrator 8 installed in the middle of the metal frame 1, and a second transmission wheel 9 connected to the output end of the mechanical vibrator 8. A transmission belt 10 is connected between 9 and the two sets of first transmission wheel discs 7 respectively. A transmission rod 11 is also provided between the mechanical vibrator 8 and the bottom of the grading and screening component 2. The petroleum coke grading device realizes the synchronous drive of the negative pressure extractor 3 and the mechanical vibrator 8 through a set of drive motors 6. When the negative pressure extractor 3 and the mechanical vibrator 8 run at the same time, it can not only perform fine screening of the petroleum coke particles to be processed, but also extract and collect the petroleum coke powder adhering to the surface of the petroleum coke particles, so as to avoid the waste of petroleum coke powder resources and prevent the petroleum coke powder from generating dust in the rolling state.

[0026] The grading and screening assembly 2 includes a screening plate frame 12, with a grading and screening component 13 connected inside the screening plate frame 12. A feeding hopper 14 is also provided at one end of the screening plate frame 12. The grading and screening component 13 installed inside the screening plate frame 12 is used for fine screening of petroleum coke particles of different specifications. A baffle plate 15 is installed at the bottom of the screening plate frame 12, and a first discharge hopper 16 is provided at one end of the baffle plate 15. A first mounting groove 17 is formed around the inner perimeter of the screening plate frame 12 near the baffle plate 15. 7. A second hopper 18 is connected to one end near the first hopper 16. The baffle plate 15 installed at the bottom of the screening plate frame 12 can block and discharge the filtered petroleum coke particles. A second mounting groove 19 is provided on the inner side of the screening plate frame 12 near the opening. A third hopper 20 is connected to one end of the second mounting groove 19 near the second hopper 18. The third hopper 20 installed at one end of the second mounting groove 19 is used to discharge the filtered petroleum coke particles outward.

[0027] The grading and screening component 13 includes a first filter screen plate 21, which is installed inside the first mounting groove 17. A second filter screen plate 22 is provided on the top of the first filter screen plate 21 and connected inside the second mounting groove 19. The grading and screening component 13 is composed of the first filter screen plate 21 and the second filter screen plate 22, which can perform fine screening of petroleum coke particles of different specifications. The aperture of the second filter screen plate 22 is larger than that of the first filter screen plate 21. The first filter screen plate 21 is on the same horizontal plane as the second discharge hopper 18, and the second filter screen plate 22 is on the same horizontal plane as the third discharge hopper 20. Due to the structural design that the first filter screen plate 21 and the second discharge hopper 18 are on the same horizontal plane, petroleum coke particles that have not passed through the first filter screen plate 21 can be discharged outward through the second discharge hopper 18. Similarly, due to the structural design that the second filter screen plate 22 and the third discharge hopper 20 are on the same horizontal plane, petroleum coke particles that have not passed through the second filter screen plate 22 can be discharged outward through the third discharge hopper 20.

[0028] Working Principle: This solution utilizes a negative pressure extractor 3 installed on one side of the grading and screening assembly 2. This negative pressure extractor 3, through the combined action of the drive motor 6, the first transmission wheel 7, the mechanical vibrator 8, the second transmission wheel 9, the transmission belt 10, and the transmission rod 11, provides vibration force to the screening plate frame 12 installed in the middle of the metal frame 1, while simultaneously driving the negative pressure extractor 3 to operate synchronously. When the petroleum coke particles to be processed are subjected to the force of the mechanical vibrator 8, they are expelled from the opening on one side of the bottom of the feeding hopper 14. When the material flows into the screening plate frame 12, it is extracted through the extraction pipe 4 installed at the extraction port of the negative pressure extractor 3. The extraction port of the extraction pipe 4 is located on one side of the opening of the feeding hopper 14. This allows for dust collection of the petroleum coke particles discharged by vibration. The petroleum coke powder adhering to the surface of the petroleum coke particles can be drawn into the negative pressure extractor 3 and discharged outward through the connecting flange 5 installed at the discharge port of the negative pressure extractor 3. By connecting the container for collecting petroleum coke powder to one end of the connecting flange 5, it is convenient to collect the petroleum coke powder.

[0029] The grading and screening component 2 designed in this scheme mainly consists of a screening plate frame 12, a grading and screening component 13, and a feeding hopper 14. The grading and screening component 13 includes a first filter screen 21 and a second filter screen 22, and the aperture of the second filter screen 22 is larger than that of the first filter screen 21. When the screening plate frame 12 is driven by the mechanical vibrator 8, it can shake violently on the top of the metal frame 1. The violently vibrating screening plate frame 12 can discharge petroleum coke particles from the inside of the feeding hopper 14. The discharged petroleum coke particles can roll along the inclination of the screening plate frame 12. When the particle size of the petroleum coke particles is smaller than the aperture of the second filter screen 22, the petroleum coke particles can pass through the second filter screen 22 and fall on the surface of the first filter screen 21. The petroleum coke particles that do not pass through the second filter screen 22 can be discharged outward through the third discharge hopper 20, while the petroleum coke particles that fall onto the surface of the first filter screen 21 can undergo secondary screening.

[0030] When the particle size of the petroleum coke particles is smaller than the aperture of the first filter screen 21, the petroleum coke particles can pass through the first filter screen 21 and fall onto the surface of the baffle plate 15. Then, they can be discharged outward through the first discharge hopper 16 installed at one end of the baffle plate 15. The petroleum coke particles that do not pass through the first filter screen 21 can be discharged outward through the second discharge hopper 18. As can be seen from the above, the petroleum coke grading device designed in this scheme realizes the synchronous drive of the negative pressure extractor 3 and the mechanical vibrator 8 through a set of drive motors 6. When the negative pressure extractor 3 and the mechanical vibrator 8 run simultaneously, not only can the petroleum coke particles to be processed be finely screened, but the petroleum coke powder adhering to the surface of the petroleum coke particles can also be extracted and collected. This avoids the waste of petroleum coke powder resources and also prevents the petroleum coke powder from generating dust while rolling.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
