Description

Technical Field

[0001] This utility model relates to the field of calcined coke processing technology, and in particular to a forming press for calcined coke. Background Technology

[0002] Calcinated coke is the product of petroleum coke after high-temperature calcination. Calcination of petroleum coke is an important step in carbon production. It involves high-temperature calcination under air-isolated conditions to remove volatiles and moisture from the raw materials. During calcination, the structure and elemental composition of various carbonaceous raw materials undergo a series of profound changes, resulting in calcined coke. In appearance, coke is an irregularly shaped, black block (or granular) material of varying sizes with a metallic luster. Calcinated petroleum coke is mainly used for prebaked anodes and cathodes in electrolytic aluminum production, as a carbon raiser in the metallurgical and steel industries, as a graphite electrode, and as a carbon electrode for industrial silicon, yellow phosphorus, and ferroalloys.

[0003] According to Chinese Patent Publication No. CN222645431U, a patent document entitled "A Forming Press for Calcined Coke" is disclosed. The existing forming press does not have a screening structure. The simultaneous extrusion of calcined coke of different particle sizes will affect the extrusion density, resulting in poor forming effect of calcined coke. Furthermore, the existing forming press cannot control the falling and stopping of calcined coke to achieve quantitative control, which leads to insufficient feeding accuracy and affects the forming precision of calcined coke. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the forming press does not have a screening structure, resulting in poor forming effect of calcined coke and the inability to quantitatively control the feeding of calcined coke, which affects the forming accuracy of calcined coke. Therefore, a forming press for calcined coke is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A forming press for calcined coke includes a first drive motor, a second drive motor, and a support frame. A conveying component is fixedly connected to the output end of the first drive motor. A screening cylinder is fixedly mounted on the support frame. A discharge port is opened at the bottom of the screening cylinder, and a first filter plate is fixedly mounted on the discharge port. A second filter plate is fixedly mounted at the end of the screening cylinder away from the first drive motor. A collection box is snapped into the screening cylinder by two clips. A discharge pipe is fixedly mounted on the discharge port. A moving frame is fixedly connected to the bottom end of the screening cylinder via a first contraction rod. A blocking block is fixedly mounted on the moving frame, and the blocking block is perpendicular to the discharge pipe. A fixed frame is fixedly connected to the bottom end of the moving frame via a second contraction rod. A first return spring is coaxially mounted on the first contraction rod, and a second return spring is coaxially mounted on the second contraction rod. A rotating shaft is fixedly connected to the output end of the second drive motor, and an extrusion block is coaxially fixedly sleeved on the rotating shaft.

[0007] Preferably, the first drive motor is fixedly mounted on the support frame, a feed pipe is installed on the screening cylinder, and multiple circular holes are opened on both the first filter plate and the second filter plate, wherein the diameter of the circular holes on the second filter plate is larger than the diameter of the circular holes on the first filter plate.

[0008] Preferably, the conveying component is located inside the screening cylinder, the inner wall of the collection box is provided with an arc-shaped groove, and the collection box is sleeved on the outer surface of the second filter plate.

[0009] Preferably, a fixed frame is provided below the collection box, the two ends of the first return spring are fixedly connected to the screening cylinder and the moving frame respectively, and the two ends of the second return spring are fixedly connected to the moving frame and the fixed frame respectively.

[0010] Preferably, the second drive motor is fixedly mounted on the fixed frame, and support rods are fixedly connected to both sides of the fixed frame. The moving frame slides on the two support rods, and the second retractable rod is located between the two support rods.

[0011] Preferably, an electric telescopic rod is fixedly installed on the support frame, a pressure plate is fixedly connected to the electric telescopic rod, a feeding pipe is fixedly connected to the bottom end of the moving frame, a processing box is fixedly connected to the feeding pipe, and the pressure plate is located inside the processing box.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model adopts a first drive motor with a conveying component fixedly connected to the output end, a first filter plate fixedly installed on the discharge port, and a second filter plate fixedly installed at the end of the screening cylinder away from the first drive motor. When the first drive motor is started, the conveying component is driven to rotate, and the conveying component pushes the calcined coke toward the collection box. During the movement, the calcined coke passes through the first filter plate and the second filter plate in succession. The first filter plate and the second filter plate screen according to the particle size of the calcined coke, so that the density of the calcined coke extrusion molding is stable and the molding effect is improved.

[0014] 2. This utility model employs a rotating shaft coaxially fixedly fitted with an extrusion block, and a blocking block fixedly installed on the moving frame. A first retraction rod is coaxially equipped with a first return spring, and a second retraction rod is coaxially equipped with a second return spring. A second drive motor drives the rotating shaft to rotate, and the rotating shaft drives the extrusion block to periodically extrude the moving frame. However, when the moving frame is extruded and descends, the first return spring stretches and the second return spring compresses, allowing the calcined coke to pass through the moving frame. When the extrusion block continues to rotate and moves away from the moving frame, the first and second return springs drive the moving frame to rise, causing the blocking block to seal the feeding pipe and prevent the calcined coke from falling. This achieves quantitative control of the calcined coke feeding and improves the accuracy of calcined coke forming. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3The calcined coke forming press includes a first drive motor 1, a second drive motor 2, and a support frame 3. The output end of the first drive motor 1 is fixedly connected to a conveying component 5. A screening cylinder 4 is fixedly installed on the support frame 3. The conveying component 5 consists of a rotating shaft and a spiral blade. The calcined coke is fed into the screening cylinder 4 through the feed pipe. The first drive motor 1 is started to drive the rotating shaft to rotate. Under the rotation of the rotating shaft, the spiral blade can push the calcined coke in the screening cylinder 4 toward the side where the collection box 8 is located.

[0021] A first filter plate 6 is fixedly installed on the discharge port, a first drive motor 1 is fixedly installed on the support frame 3, and a feed pipe is installed on the screening cylinder 4. Both the first filter plate 6 and the second filter plate 7 have multiple circular holes. The diameter of the circular holes on the second filter plate 7 is larger than the diameter of the circular holes on the first filter plate 6. The calcined coke will pass through the first filter plate 6 under the conveying of the conveyor 5, and the particles with smaller diameters will fall off the first filter plate 6.

[0022] A second filter plate 7 is fixedly installed at the end of the screening cylinder 4 away from the first drive motor 1. The screening cylinder 4 is connected to a collection box 8 by two buckles. The conveying component 5 is located inside the screening cylinder 4. The inner wall of the collection box 8 has an arc-shaped groove. The collection box 8 is sleeved on the outer surface of the second filter plate 7. Larger particles cannot pass through the first filter plate 6 and continue to move towards the second filter plate 7 under the action of the conveying component 5. After being screened by the second filter plate 7, they fall into the collection box 8. The collection box 8 can be disassembled by pressing the buckle. The calcined coke is screened by the first filter plate 6 and the second filter plate 7 to avoid the uneven particle size of the calcined coke affecting the extrusion molding density.

[0023] The bottom end of the screening cylinder 4 is provided with a discharge port, and a discharge pipe is fixedly installed on the discharge port. The bottom end of the screening cylinder 4 is fixedly connected to the moving frame 11 through the first contraction rod 13. A blocking block 14 is fixedly installed on the moving frame 11. The blocking block 14 is perpendicular to the discharge pipe. The bottom end of the moving frame 11 is fixedly connected to the fixing frame 15 through the second contraction rod 18. The first contraction rod 13 is coaxially provided with a first return spring 12, and the second contraction rod 18 is coaxially provided with a second return spring 17. The output end of the second drive motor 2 is fixedly connected to a rotating shaft 9. The rotating shaft 9 is coaxially fixedly sleeved with a squeezing block 10. The fixing frame 15 is provided below the collection box 8. The two ends of the first return spring 12 are fixedly connected to the screening cylinder 4 and the moving frame 11, respectively. The two ends of the second return spring 17 are fixedly connected to the moving frame 11 and the fixing frame 15, respectively.

[0024] The second drive motor 2 is fixedly mounted on the fixed frame 15. The calcined coke, after being screened by the first filter plate 6, falls through the feeding pipe. The second drive motor 2 is then activated, driving the rotating shaft 9 to rotate. During rotation, the rotating shaft 9 drives the extrusion block 10 to rotate synchronously. The extrusion block 10 is fan-shaped, allowing it to periodically extrude force into the moving frame 11. When the extrusion block 10 extrudes the moving frame 11, the moving frame 11 is compressed and descends, compressing the second return spring 17 and the second contraction rod 18. Simultaneously, it stretches the first return spring 12 and the first contraction rod 13. The moving frame 11 then drives the blocking block 14 to descend synchronously, moving the blocking block 14 away from the feeding pipe. Two strip-shaped openings are provided on the moving frame 11. The calcined coke falling from the feed pipe passes through the strip opening, passes through the motion frame 11, and falls into the feed pipe 22. During this process, the rotating shaft 9 continues to drive the extrusion block 10 to rotate. During the rotation, the extrusion block 10 will disconnect from the motion frame 11. The first return spring 12 and the second return spring 17, which are compressed, begin to return to their original positions and drive the motion frame 11 to rise. The motion frame 11 drives the blocking block 14 to rise synchronously. During the rise, the blocking block 14 will enter the feed pipe and completely block the feed pipe, thereby preventing the calcined coke from falling from the feed pipe. After the extrusion block 10 rotates once, it compresses the motion frame 11 again. The motion frame 11 repeats the above movement, thereby realizing quantitative control of the calcined coke feeding and providing calcined coke forming accuracy.

[0025] The fixed frame 15 is fixedly connected to two support rods 16 on both sides. The moving frame 11 slides on the two support rods 16. The second retractable rod 18 is located between the two support rods 16. The support rods 16 keep the movement of the moving frame 11 stable. A baffle is fixed at the top of the support rod 16 to prevent the moving frame 11 from falling off the support rod 16 during the sliding process.

[0026] An electric telescopic rod 19 is fixedly installed on the support frame 3. The electric telescopic rod 19 is fixedly connected to the pressure plate 21. The bottom end of the moving frame 11 is fixedly connected to the feeding pipe 22. The feeding pipe 22 is fixedly connected to the processing box 20. The pressure plate 21 is located inside the processing box 20. The inner wall of the feeding pipe 22 is inclined. The calcined coke falls into the processing box 20 through the feeding pipe 22. The electric telescopic rod 19 is activated to drive the pressure plate 21 to descend. The pressure plate 21 extrudes the calcined coke in the processing box 20 into shape.

[0027] The first drive motor 1 and the second drive motor 2 can be three-phase asynchronous motors YE3-225S-437KW4, which is the current technology, so this application does not describe it in detail.

[0028] It should be noted that the specific model and specifications to be adopted need to be determined based on the actual specifications of the device. The specific selection and calculation methods use existing technology in this field, so they will not be elaborated here.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] The system includes a first drive motor 1, a second drive motor 2, and a support frame 3. A conveyor 5 is fixedly connected to the output end of the first drive motor 1. A screening cylinder 4 is fixedly mounted on the support frame 3. A discharge port is opened at the bottom of the screening cylinder 4, and a first filter plate 6 is fixedly mounted on the discharge port. A second filter plate 7 is fixedly mounted at the end of the screening cylinder 4 away from the first drive motor 1. A collection box 8 is snapped onto the screening cylinder 4 by two clips. A discharge pipe is fixedly mounted on the discharge port. A moving frame 11 is fixedly connected to the bottom end of the screening cylinder 4 via a first contraction rod 13. A blocking block 14 is fixedly mounted on the moving frame 11, and the blocking block 14 is perpendicular to the discharge pipe. A fixing frame 15 is fixedly connected to the bottom end of the moving frame 11 via a second contraction rod 18. A first return spring 12 is coaxially mounted on the first contraction rod 13, and a second return spring 17 is coaxially mounted on the second contraction rod 18. The output end of the second drive motor 2... A rotating shaft 9 is fixedly connected, and an extrusion block 10 is coaxially fixedly sleeved on the rotating shaft 9. When the first drive motor 1 is started, the first drive motor 1 drives the conveyor 5 to rotate. The conveyor 5 pushes the calcined coke through the first filter plate 6 and the second filter plate 7 in sequence, thereby screening the calcined coke and avoiding the impact of uneven particle size on the extrusion molding density. When the second drive motor 2 is started, the second drive motor 2 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the extrusion block 10 to rotate. During the rotation, the extrusion block 10 periodically extrudes the moving frame 11. When the moving frame 11 is extruded, it stretches the first return spring 12 and compresses the second return spring 17. The extrusion block 10 continues to rotate and disconnects from the moving frame 11. The moving frame 11 rises under the reset action of the first return spring 12 and the second return spring 17, thereby blocking the feeding pipe and preventing the calcined coke from falling, thus realizing quantitative control of the calcined coke feeding.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
