Description

Technical Field

[0001] This invention belongs to the field of petroleum coke production technology, and particularly relates to an integrated device for precise proportioning and homogenization of multiple raw materials for petroleum coke production. Background Technology

[0002] Petroleum coke is a core raw material in the production of carbon products and the preparation of prebaked anodes. Due to differences in crude oil origin and refining process, petroleum coke from different batches and sources varies significantly in terms of particle size distribution, sulfur content, ash content, volatile matter, and other indicators. A single type of petroleum coke usually cannot directly meet the performance standards of downstream production. Therefore, in actual production, it is necessary to uniformly mix various types of petroleum coke with different particle sizes and qualities in a fixed proportion. By blending and adjusting, a mixed coke with stable indicators that meets production requirements is produced, thereby ensuring the quality stability of downstream products.

[0003] In current petroleum coke blending operations, the accuracy of ingredient proportioning is insufficient. Most production scenarios rely on manual estimation or simple screw feeding to control the amount of material fed, lacking a precise quantitative control structure. This makes it difficult to accurately regulate the blending ratio of multiple raw materials, resulting in large proportioning errors. Consequently, the indicators of different batches of blended materials fluctuate significantly, directly affecting the quality of downstream carbon products. Furthermore, the equipment integration is low. Existing blending production lines mostly adopt a split layout, with quantitative ingredient proportioning, material conveying, mixing, and finished product discharge all completed by independent equipment. This results in large equipment footprints, numerous process connections, and the potential for spillage and accumulation during material transfer, leading to low production efficiency and poor discharge results. Conventional mixing equipment often uses a fixed bottom discharge port, which easily leaves material residue in the container. This residual coke can mix into the next batch of raw materials, compromising the preset proportioning accuracy. Some equipment with tilting discharge lacks a precise quantitative feeding structure, making it impossible to achieve integrated operation of proportioning, homogenization, and discharge throughout the entire process. Therefore, we propose an integrated device for precise proportioning and homogenization of multiple petroleum coke raw materials. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated device for precise proportioning and homogenization of multiple raw materials for petroleum coke, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an integrated device for precise proportioning and homogenization of multiple raw materials for petroleum coke, comprising: A base plate, a rotating frame is fixedly installed on the top of the base plate, a mixing tank is rotatably installed inside the rotating frame, a rotating rod is rotatably installed inside the mixing tank, several stirring rods are fixedly installed around the rotating rod, a guide nozzle is fixedly installed on one side of the mixing tank, and a drive motor is fixedly installed at the bottom of the mixing tank. The output end of the drive motor passes through the bottom of the mixing tank and is coaxially connected to the rotating rod. A power assembly, located within a rotating frame, is used to drive the mixing drum to rotate; A fixed frame is fixedly installed on the top of the base plate and located on one side of the mixing tank. An installation plate is fixedly installed on the top of the fixed frame, and a conveyor belt is provided inside the installation plate. An installation frame is fixedly installed on one side of the fixed frame, and several material boxes are fixedly installed on one side of the installation frame. A conveying box is fixedly installed at the bottom of the material box, and a discharge pipe is fixedly installed at the bottom of the conveying box. A baffle plate is fixedly installed at one end of the discharge pipe. A plurality of metering components are located in a plurality of conveying bins and are used to meter the materials in the plurality of loading bins.

[0006] In this technical solution, several loading boxes on the mounting frame contain petroleum coke raw materials of different particle sizes. The bottom of each loading box is connected to the corresponding conveyor box. During quantitative operation, the quantitative component completes the quantitative distribution of a single part of the material. After being guided by the baffle plate at the end of the discharge pipe, it falls stably onto the conveyor belt below, ensuring the quantitative accuracy of each part of the material. By controlling several quantitative components, the total discharge amount of different loading boxes can be adjusted accordingly, so as to achieve the precise proportion of petroleum coke of various particle sizes. After all the materials are fed into the mixing drum, the drive motor starts and its output end drives the rotating rod to rotate inside the mixing drum. Several stirring rods distributed in a ring at equal intervals around the rotating rod rotate synchronously with the rotating rod, continuously stirring the petroleum coke raw materials of various particle sizes in the drum, so that the materials of different particle sizes are fully mixed and uniform, and the material homogenization operation is completed. After the materials are mixed, the first drive motor stops running, and the power component inside the rotating frame starts. The power component drives the mixing drum to deflect and tilt around the rotating connection of the rotating frame. The guide nozzle on one side of the mixing drum tilts to a low position synchronously with the drum body. The uniformly mixed petroleum coke material inside the drum is automatically discharged outward through the guide nozzle under the action of gravity, realizing automatic discharge. After the discharge is completed, the second drive motor rotates in the opposite direction and drives the mixing drum to return to the vertical position through gear transmission, so that the next round of proportioning and homogenizing operation can begin.

[0007] In the above technical solution, the power component further includes; A drive slot is formed inside a rotating frame. A gear 1 is rotatably installed inside the drive slot. One end of the gear 1 passes through one side of the drive slot and is coaxially connected to the mixing tank. A gear 2 is meshed at the bottom of the gear 1 and located inside the drive slot. A drive motor 2 is fixedly installed on one side of the rotating frame. The output end of the drive motor 2 passes through one side of the rotating frame and is coaxially connected to the gear 2.

[0008] In this technical solution, after the materials are mixed, the first drive motor stops running, the power component inside the rotating frame starts, and the second drive motor drives the second gear to rotate in the drive groove. The second gear meshes with the first gear, which in turn causes the mixing drum, which is coaxially connected to the gear, to deflect and tilt around the rotating connection of the rotating frame. The guide nozzle on one side of the mixing drum tilts to a low position synchronously with the drum body. The uniformly mixed petroleum coke material inside the drum is automatically discharged outward through the guide nozzle under the action of gravity, realizing automatic discharge. After the discharge is completed, the second drive motor rotates in the opposite direction, and through gear transmission, it drives the mixing drum to return to the vertical position, so that the next round of proportioning and homogenization operation can begin.

[0009] In the above technical solution, the second gear is rotatably connected to the drive slot, and the output shaft of the second drive motor is rotatably connected to the rotating frame.

[0010] In this technical solution, it is ensured that gear two can rotate normally in the drive slot, and that the output shaft of drive motor two can rotate normally in the rotating frame.

[0011] In the above technical solution, the quantitative component further includes: A rotating groove is provided inside the feeding box. A rotating block is rotatably installed inside the rotating groove. A sealing ring is fixedly installed on the periphery of the rotating block. A metering groove is symmetrically provided on the periphery of the rotating block. A drive motor is fixedly installed on one side of the feeding box. The output end of the drive motor passes through one side of the feeding box and is coaxially connected to the rotating block.

[0012] In this technical solution, several loading boxes on the mounting frame contain petroleum coke raw materials of different particle sizes. The bottom of each loading box is connected to the corresponding conveying box. During quantitative operation, the drive motor four on one side of the conveying box starts, driving the rotating block to rotate at a constant speed in the rotating groove. Quantitative grooves are symmetrically opened on the periphery of the rotating block. When the quantitative groove rotates to the upward position, the petroleum coke material in the loading box falls naturally and fills the quantitative groove, completing the quantitative measurement of a single portion of material. As the rotating block continues to rotate, the quantitative groove containing the material rotates to the downward position, and the quantitatively measured petroleum coke material in the groove falls into the discharge pipe. After being guided by the baffle plate at the end of the discharge pipe, it falls stably onto the conveyor belt below. The sealing ring on the periphery of the rotating block fits tightly with the inner wall of the rotating groove, preventing material leakage from the rotating gap and ensuring the quantitative accuracy of each portion of material. By controlling the rotation frequency and speed of each drive motor four, the total discharge amount of different loading boxes can be adjusted accordingly, achieving precise proportioning of petroleum coke of various particle sizes.

[0013] In the above technical solution, the periphery of the sealing ring is in close contact with the inner wall of the rotating groove, and the output shaft of the drive motor is rotatably connected to the material conveying box.

[0014] In this technical solution, the sealing of the rotating groove is improved, ensuring that the output shaft of the drive motor can rotate normally inside the material conveying box.

[0015] In the above technical solution, two rotating rollers are rotatably mounted on the mounting plate and located inside the conveyor belt. A drive motor three is fixedly mounted on one side of the mounting plate, and the output end of the drive motor three passes through one side of the mounting plate and is coaxially connected to one of the rotating rollers.

[0016] In this technical solution, the fixed frame is fixedly installed on the top of the base plate. A conveyor belt is set on the mounting plate on the top of the fixed frame. During the conveying operation, the drive motor starts three times, driving one of the rotating rollers to rotate. The two rotating rollers cooperate to tension and drive the conveyor belt to continuously circulate, conveying the proportioned petroleum coke material falling from each discharge pipe forward and finally into the mixing tank below to complete the feeding.

[0017] In the above technical solution, furthermore, the circumferences of both rotating rollers abut against the inner wall of the conveyor belt, and the output shaft of the drive motor is rotatably connected to the mounting plate.

[0018] In this technical solution, the conveyor belt's conveying stability is ensured, and the output shaft of the third drive motor is guaranteed to rotate normally within the mounting plate.

[0019] In the above technical solution, the output shaft of the drive motor is rotatably connected to the mixing tank, and the plurality of stirring rods are distributed in a ring at equal intervals.

[0020] In this technical solution, it is ensured that the output shaft of the drive motor can rotate normally inside the mixing tank, and that the distribution of the stirring rods is uniform.

[0021] The beneficial effects of this invention are: 1. This integrated device for precise proportioning and homogenization of multiple petroleum coke raw materials features a mounting frame with multiple independent loading and conveying boxes, capable of holding petroleum coke raw materials of different particle sizes. Each conveying box is equipped with an independent metering component. Driven by a motor, a rotating block is rotated, and symmetrical metering grooves on the rotating block achieve volumetric metering. The volume of a single material is fixed and controllable. By adjusting the rotation speed and frequency of the drive motor, the total amount of corresponding raw materials can be flexibly adjusted to achieve precise proportioning of various petroleum cokes, ensuring the consistency of the mixing ratio in each batch and effectively improving the stability of the finished coke's properties. The sealing rings on the periphery of the rotating block fit tightly against the inner wall of the rotating groove, effectively preventing petroleum coke particles from leaking through the rotation gaps, reducing material loss, and preventing particle wear on parts. This maintains metering accuracy over the long term and reduces equipment maintenance costs.

[0022] 2. This integrated petroleum coke multi-raw material precise proportioning and homogenization device integrates a quantitative batching structure, a conveyor belt conveying structure, a mixing structure, and a tilting discharge structure on the bottom, forming an integrated operation unit. It eliminates the need for multiple separate equipment, significantly reducing the equipment footprint. After the raw materials are quantitatively discharged from the loading box, they are directly conveyed into the mixing tank by the conveyor belt. After mixing, the material is directly discharged through the tilting of the mixing tank. The entire process is smoothly connected, reducing intermediate transfer links and avoiding material spillage and accumulation. It can realize continuous blending and homogenization operations, effectively improving the production efficiency of petroleum coke blending.

[0023] 3. This integrated device for precise proportioning and homogenization of multiple raw materials in petroleum coke uses a drive motor to rotate a rotating rod and several stirring rods synchronously within the mixing drum. This allows for comprehensive mixing of petroleum coke of various particle sizes, breaking down material stratification and dead zones. It ensures thorough cross-mixing of raw materials of different particle sizes and qualities, resulting in homogeneous mixed coke in a short time. The excellent homogenization effect fully meets the downstream production requirements for raw material uniformity. The mixing drum is rotatably mounted within a rotating frame. Gear transmission from the power unit drives the mixing drum to tilt and deflect. Combined with the guide nozzle on the side of the mixing drum, the mixed petroleum coke is completely discharged under gravity, leaving no material residue in the drum. This completely prevents residual coke from interfering with the proportioning accuracy of subsequent batches, ensuring the accuracy of the proportioning for each batch. After discharge, the power unit automatically resets the mixing drum, allowing for rapid entry into the next operation. The device is convenient and efficient to operate. Attached Figure Description

[0055] Working principle: Several loading boxes 18 on the mounting frame 17 contain petroleum coke raw materials of different particle sizes. The bottom of each loading box 18 is connected to the corresponding conveying box 19. During quantitative operation, the drive motor 24 on one side of the conveying box 19 starts, driving the rotating block 21 to rotate at a constant speed in the rotating groove 20. The rotating block 21 has symmetrically arranged quantitative grooves 23 on its circumference. When the quantitative groove 23 rotates to the upward position, the petroleum coke material in the loading box 18 falls naturally and fills the quantitative groove 23, completing the quantitative measurement of a single part of material. As the rotating block 21 continues to rotate... The metering trough 23 containing the material rotates to the downward position, and the metered amount of petroleum coke material in the trough falls into the discharge pipe 25. After being guided by the baffle plate 26 at the end of the discharge pipe 25, it falls stably onto the conveyor belt 15 below. The sealing ring 22 on the side of the rotating block 21 fits tightly against the inner wall of the rotating trough 20 to prevent the material from leaking from the rotation gap, ensuring the metering accuracy of each part of the material. By controlling the rotation frequency and speed of each drive motor 24, the total discharge amount of different loading boxes 18 can be adjusted accordingly to achieve the precise proportion of petroleum coke of various particle sizes. The fixed frame 12 is fixedly installed on the top of the base plate 1. The mounting plate 13 on the top of the fixed frame 12 is equipped with a conveyor belt 15. During the conveying operation, the drive motor 16 starts and drives one of the rotating rollers 14 to rotate. The two rotating rollers 14 cooperate to tension and drive the conveyor belt 15 to continuously circulate, conveying the proportioned petroleum coke material that falls from each discharge pipe 25 forward and finally into the mixing tank 3 below to complete the feeding. After all the materials are fed into the mixing tank 3, the drive motor 7 starts, and its output end drives the rotating rod 4 to rotate inside the mixing tank 3. Several stirring rods 5, which are distributed in a ring at equal intervals around the rotating rod 4, rotate synchronously with the rotating rod 4 to continuously stir the petroleum coke raw materials of various particle sizes in the tank, so that the materials of different particle sizes are fully mixed and uniform, and the material homogenization operation is completed. After the materials are mixed, drive motor 7 stops running, and the power component in the rotating frame 2 starts. Drive motor 11 drives gear 10 to rotate in the drive groove 8. Gear 10 meshes with gear 9, which in turn causes the mixing drum 3, which is coaxially connected to gear 9, to deflect and tilt around the rotating connection of the rotating frame 2. The guide nozzle 6 on one side of the mixing drum 3 tilts to a low position synchronously with the drum body. The uniformly mixed petroleum coke material in the drum is automatically discharged outward through the guide nozzle 6 under the action of gravity, realizing automatic discharge. After the discharge is completed, drive motor 11 rotates in reverse and drives the mixing drum 3 to return to the vertical position through gear transmission, so that the next round of proportioning and homogenization operation can begin.
