Description

Technical Field

[0001] This invention belongs to the field of mixing equipment technology, specifically relating to a raw material proportioning and mixing equipment for blending petroleum coke. Background Technology

[0002] Petroleum coke blending equipment is a core process in industries such as petrochemicals, carbon, and fuels. The core objective of petroleum coke blending is to obtain a blended coke with stable and uniform performance that meets the requirements of downstream production by mixing raw coke of different qualities in a specific ratio.

[0003] Traditional petroleum coke mixing equipment generally has many shortcomings. First, the mixing process is mostly open-loop control, lacking real-time monitoring and feedback adjustment of material discharge, making it difficult to accurately control the mixing ratio and residence time, resulting in unstable mixing uniformity and poor batch consistency. Second, conventional mixing structures are mostly single-channel or simple stirring, which easily creates flow dead zones and insufficient material cross-convection, which can easily affect production continuity and efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a raw material proportioning and mixing device for blending petroleum coke, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A raw material proportioning and mixing device for blending petroleum coke includes a flow channel module and a stirring roller module. The flow channel module is provided with a set of parallel flow channels arranged in a W shape, and the stirring roller module is divided into two sets of parallel flow channels. The stirring roller module is equipped with an array of several rotatable stirring plates; The petroleum coke blending raw material proportioning and mixing equipment also includes an adjustment component, which is arranged at the end of the flow channel module and is used to measure the discharge amount of petroleum coke components per unit time. The stirring roller module and the adjusting component are arranged in conjunction. The rotation angle of the stirring plate on the stirring roller module is adjusted according to the discharge amount of petroleum coke components per unit time, thereby adjusting the residence time of petroleum coke components in the flow channel module.

[0006] As a further embodiment of the present invention, the flow channel module includes a flow channel component, which includes a main frame, a main flow channel, branch flow channels and a discharge hopper. The main flow channel is fixedly installed on the main frame. Two sets of parallel branch flow channels are installed inside the main flow channel. The two sets of branch flow channels are spaced apart, and the discharge hopper is connected to both sets of branch flow channels.

[0007] As a further embodiment of the present invention, the petroleum coke blending raw material proportioning and mixing equipment further includes a driving component. The driving component includes a driver, a transmission wheel, a driven gear, and a driven shaft. The driver is fixedly mounted on one side of the main frame, the transmission wheel is rotatably mounted on one side of the main frame, and two sets of driven gears are fixedly mounted on one end of the main frame. One end of the transmission wheel is connected to the driver, and the other end of the transmission wheel is coaxially and fixedly connected to any one set of driven gears. The two sets of driven gears mesh with each other, and a driven shaft is coaxially and fixedly mounted on each set of driven gears.

[0008] As a further embodiment of the present invention, the flow channel module further includes a cover assembly, which includes a front cover, a feed pipe, a rear cover, and a suction pipe. The front cover and the rear cover are both installed on the top of the main flow channel. One end of the front cover is connected to several feed pipes, and one end of the rear cover is connected to a suction pipe.

[0009] As a further embodiment of the present invention, the stirring roller module includes a stirring rod assembly, which includes a housing, a sealing ring, a reversing gear, and a stirring plate. Several housings are sequentially and fixedly connected. Several sealing rings are arranged circumferentially on the cylindrical wall of the housing. One end of the reversing gear is fixedly mounted in the sealing ring, and the other end of the reversing gear is fixedly connected to the stirring plate.

[0010] As a further embodiment of the present invention, the stirring rod assembly further includes an adjusting rod, a collar, and a adjusting gear. The adjusting rod is slidably arranged in several shells, and a collar is arranged on the inner cavity side of the adjusting rod. The collar is rotatably sleeved on the adjusting rod, and several adjusting gears are fixedly assembled on the collar. The adjusting gears are slidably arranged in the shell and mesh with the reversing gear.

[0011] As a further embodiment of the present invention, the adjusting component includes a sliding sleeve housing, a sliding table, a guide rod, a linear motor, and a linkage frame. The sliding table is elastically slidably mounted on the sliding sleeve housing in the horizontal direction. One end of the guide rod is fixedly mounted on the main frame, and the other end of the guide rod is elastically slidably mounted on the sliding sleeve housing. One end of the linear motor is fixedly mounted on the sliding sleeve housing, and the other end of the linear motor is equipped with a linkage frame. The linkage frame and the sliding table are movably connected. The adjusting component also includes a shaft frame, a sliding guide groove, a sliding pin, and a bracket. One end of the shaft frame is fixedly connected to the adjusting rod, and the other end of the shaft frame is provided with a sliding guide groove. One end of the sliding pin is fixedly connected to the sliding sleeve housing through the bracket, and the other end of the sliding pin is limited and slidably assembled in the sliding guide groove.

[0012] As a further embodiment of the present invention, the adjusting member further includes toothed surfaces, the toothed surface array being arranged on the surface of the slide table and facing the discharge hopper side.

[0013] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art: Through a unique design that links the adjusting components with the agitator module, real-time monitoring and dynamic adjustment of the petroleum coke material discharge rate are achieved. When the discharge rate per unit time at the end of the discharge hopper changes, the adjusting components can respond quickly and automatically adjust the rotation angle of the agitator through the linkage mechanism, thereby changing the flow resistance and propulsion speed of the material in the diversion channel, forming a closed-loop control mechanism. This not only ensures the stability of the material output flow rate, but also allows for flexible control of the material residence time in the mixing channel by adjusting the agitator angle, improving the mixing uniformity and process controllability, and meeting the requirements of different proportions and processing rates. Furthermore, the equipment adopts a W-shaped parallel flow channel layout, combined with two sets of counter-rotating agitator modules, so that the material forms an ∞-shaped circulating motion trajectory between the flow channels. Under the dual action of circumferential and axial directions, the agitator plate not only enhances the radial tumbling and diffusion of the material, but also provides continuous propulsion along the flow channel direction. This structure effectively avoids flow dead zones and realizes repeated convection and cross-mixing of materials in space, which significantly improves the uniformity of distribution of various components of petroleum coke. At the same time, the airtight design of the cover assembly combined with the dust collection pipeline effectively suppresses dust emission and ensures a clean and safe working environment. Furthermore, the adjusting rod, collar, and adjusting gear in the agitator module form a precision transmission structure that enables synchronous and precise adjustment of the angle of all agitators. It integrates a linear motor, elastic sliding pair, and toothed pushing mechanism, which can automatically adjust the movement state of the slide table according to the material load and promote the orderly discharge of materials. This achieves fully automated control from material input and mixing to output, reducing manual intervention, improving production efficiency and process consistency, and is suitable for continuous and large-scale petroleum coke blending production scenarios.

Detailed Implementation

[0027] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please see Figures 1-9According to one embodiment of the present invention, a raw material proportioning and mixing device for blending petroleum coke includes a flow channel module and a stirring roller module. The flow channel module is provided with a set of parallel flow channels arranged in a W shape, and the stirring roller module is disposed in two sets of parallel flow channels. A plurality of rotatable agitator plates 404 are arranged in an array on the stirring roller module. The raw material proportioning and mixing device for blending petroleum coke also includes an adjustment component 5, which is disposed at the end of the flow channel module and is used to measure the discharge amount of petroleum coke components per unit time. The stirring roller module and the adjustment component 5 are linked and the rotation angle of the agitator plates 404 on the stirring roller module is adjusted according to the discharge amount of petroleum coke components per unit time, thereby adjusting the residence time of petroleum coke components in the flow channel module.

[0029] In practical application, the petroleum coke blending equipment in this embodiment consists of a flow channel module and a stirring roller module. The flow channel module contains a set of parallel, W-shaped spatial topology-arranged continuous flow channels. Within this W-shaped flow channel structure are two independent sub-channels 103, each sub-channel 103 equipped with an independently operating stirring roller module. At the end of the flow channel module is an adjusting component 5 for real-time measurement of the mass of petroleum coke material discharged per unit time. This adjusting component 5 dynamically adjusts the rotation angle of the stirring plate 404 on the stirring roller module through a closed-loop system based on the average discharge mass data of each component of the petroleum coke fed back by the online monitoring system. When the rotation angle of the stirring plate 404 changes, the petroleum coke material inside the sub-channel 103 will undergo significant changes due to the hydrodynamic force applied by the stirring plate 404. Under the combined action of tangential shear force and axial propulsion force, the material not only achieves circumferential tumbling but also obtains continuous... The forward directional conveying momentum allows the total residence time of petroleum coke material inside the diversion channel 103 to be controlled by the inclination angle of the agitator 404. When the total discharge of petroleum coke components per unit time shows a downward trend, the adjusting component 5 will drive the agitator 404 to increase its rotation angle, thereby enhancing the axial thrust on the material and increasing the conveying rate. Conversely, the inclination angle will be reduced to prolong the residence time. Through this dynamic feedback adjustment mechanism, the material flow parameters can be corrected in real time to ensure that the total discharge of each component of petroleum coke per unit time remains stable, ultimately achieving high-precision and continuous control of the proportioning and mixing process.

[0030] Please see Figure 2 and Figure 3 In a preferred embodiment of the present invention, the flow channel module includes a flow channel component 1, which includes a main frame 101, a main flow channel 102, a branch flow channel 103, and a discharge hopper 104. The main frame 101 is fixedly provided with the main flow channel 102, and two sets of parallel branch flow channels 103 are provided inside the main flow channel 102. The two sets of branch flow channels 103 are spaced apart, and the discharge hopper 104 is connected to both sets of branch flow channels 103.

[0031] In practical application, this embodiment has two sets of parallel branch channels 103 configured in the main channel 102 within the main frame 101. The two branch channels 103 are arranged in a W-shape. Based on this configuration, a longitudinally extending protruding structural ridge is formed in the area between the two branch channels 103. This structure guides the petroleum coke particles during the tumbling process to fall into either branch channel 103 in a random distribution manner, effectively avoiding the petroleum coke from being stuck in the flow dead zone during the tumbling and conveying stages. This ensures that no material is missed during continuous movement. With the help of the fluid force generated by the agitator 404 set in the channel, a propulsive force is continuously applied to the petroleum coke components along the axial direction of the branch channel 103, so that it is stably transported towards the discharge hopper 104 in the controlled flow field. This propulsion process continues in the branch channel 103 until all petroleum coke components are finally discharged through the discharge hopper 104.

[0032] Please see Figure 2 In a preferred embodiment of the present invention, the petroleum coke blending raw material proportioning and mixing equipment further includes a driving component 2. The driving component 2 includes a driver 201, a transmission wheel 202, a driven gear 203, and a driven shaft 204. The driver 201 is fixedly disposed on one side of the main frame 101. The transmission wheel 202 is rotatably disposed on one side of the main frame 101. Two sets of driven gears 203 are fixedly disposed at one end of the main frame 101. One end of the transmission wheel 202 is connected to the driver 201 for transmission. The other end of the transmission wheel 202 is coaxially fixedly connected to any one set of driven gears 203. The two sets of driven gears 203 are meshed and connected, and a driven shaft 204 is coaxially fixedly mounted on each of the two sets of driven gears 203.

[0033] In practical application, the driver 201 drives the transmission wheel 202 to rotate on a fixed axis under continuous driving. The transmission wheel 202 meshes with the left driven gear 203 through its teeth, directly driving its rotation. At the same time, the transmission wheel 202 also meshes with the right driven gear 203, thereby transmitting torque and driving it to rotate synchronously. Each of the two sets of driven gears 203 transmits rotational motion to the corresponding stirring roller module through the driven shaft 204 fixed to it. During the motion transmission process, the meshing phase of the tooth surfaces of the left and right driven gears 203 is precisely configured to ensure that the rotational directions generated by the two gears around their respective axes are always opposite in the horizontal plane or a specified reference plane. The reverse rotation relationship is completely transmitted to the two sets of stirring roller modules through the driven shaft 204, ultimately realizing that the two stirring roller modules perform synchronous, counter-rotating stirring or mixing operations in opposite directions in the plane.

[0034] In one embodiment, the rotation direction of both sets of stirring roller modules is set to inward and downward. After the petroleum coke component enters from one side of the diversion channel 103, it is propelled at high speed into the other side of the diversion channel 103 by the tangential push and centrifugal action of the stirring plate 404. Subsequently, the stirring plate 404 on the other side throws the material back into the original diversion channel 103 in the opposite direction during the reverse rotation. Through this bidirectional alternating throwing and transfer, the petroleum coke component forms a continuous ∞-shaped closed loop motion trajectory between the two component diversion channels 103, thereby realizing repeated convection and cross-diffusion of the material in three-dimensional space, significantly enhancing the uniformity of the distribution of the petroleum coke component in the axial, radial and tangential directions, and improving the overall homogenization degree and process stability of the mixing system.

[0035] Please see Figure 2 In a preferred embodiment of this embodiment, the flow channel module further includes a cover assembly 3, which includes a front cover 301, a feed pipe 302, a rear cover 303, and a suction pipe 304. The front cover 301 and the rear cover 303 are both covered on the top of the main flow channel 102. One end of the front cover 301 is connected to several feed pipes 302, and one end of the rear cover 303 is connected to the suction pipe 304.

[0036] In practical application, the multiple feed pipes 302 configured on one side of the front cover 301 are used to transport the petroleum coke material components with different particle size distributions to be mixed into the main channel 102. The front cover 301 and the rear cover 303 together cover the top area of ​​the main channel 102, forming a continuous and sealed protective structure. This structure design mainly achieves two functions: first, during the material feeding and flow process, it can effectively suppress the escape of petroleum coke dust caused by airflow disturbance or mechanical movement, thereby avoiding pollution of the surrounding environment by suspended particulate matter; second, the sealed cover can work in conjunction with the matching dust suction pipe 304 system to form a directional airflow channel inside, realizing the rapid capture and centralized suction of the escaped dust, and then efficiently exporting the captured polluting dust to the subsequent processing unit, ensuring the cleanliness of the system and dust control of the operating environment.

[0037] Please see Figure 8 In a preferred embodiment of the present invention, the stirring roller module includes a stirring rod assembly 4, which includes a housing 401, a sealing ring 402, a reversing gear 403, and a stirring plate 404. A plurality of housings 401 are sequentially fixedly connected. A plurality of sealing rings 402 are arranged circumferentially on the cylindrical wall of the housing 401. One end of the reversing gear 403 is fixedly mounted in the sealing ring 402, and the other end of the reversing gear 403 is fixedly connected to the stirring plate 404.

[0038] In practical application, the shell 401 is rotatably installed inside the diversion channel 103. Multiple sealing rings 402 are evenly distributed around the circumference of the shell. Each sealing ring 402 is fitted with a reversing gear 403 for limiting rotation. A stirring plate 404 is fixedly connected to the end of each reversing gear 403. The reversing gear 403 is arranged to penetrate the surface of the shell 401 in a vertical direction. An angle, denoted as α, is formed between the plane where the stirring plate 404 is located and the plane where the axis of the shell 401 is located. The value of the angle α ranges from 0° to 45°.

[0039] When the included angle α is set to 0°, the plane of the agitator 404 is nearly parallel to the axial plane of the shell 401. At this time, the agitator 404 has the most significant agitation effect on the petroleum coke components in the circumferential direction, which can significantly enhance the radial mixing and tumbling intensity of the material, thereby prolonging the average residence time of the petroleum coke components in the main channel 102 and improving its heat exchange and reaction efficiency in the system. At this angle, the agitator 404 has the least axial pushing effect on the material, and the material flow resistance increases accordingly. As the included angle α gradually increases to 45°, the agitator 404 gradually tends to be arranged along the axial direction, and its agitation effect in the circumferential direction weakens accordingly, but its pushing ability in the axial direction is significantly enhanced. It can effectively accelerate the forward conveying of the petroleum coke components in the main channel 102, thereby shortening its residence time in the system. By continuously adjusting the size of the included angle α, the residence time and conveying rate of the petroleum coke components in the main channel can be dynamically controlled, thereby precisely regulating the discharge flow rate of the petroleum coke components per unit time on the downstream regulating component 5 side to meet the requirements of material processing rate and mixing degree in different process stages.

[0040] Please see Figure 8 In a preferred embodiment of the present invention, the stirring rod assembly 4 further includes an adjusting rod 405, a collar 406, and a adjusting gear 407. The adjusting rod 405 is slidably arranged in a plurality of housings 401, and the collar 406 is arranged on the inner cavity side of the adjusting rod 405. The collar 406 is rotatably sleeved on the adjusting rod 405, and a plurality of adjusting gears 407 are fixedly assembled on the collar 406. The adjusting gears 407 are slidably arranged in the housings 401 and mesh with the reversing gear 403.

[0041] In practical application, the adjusting rod 405 is horizontally slidably assembled in the inner cavity of the housing 401. When the adjusting rod 405 is subjected to an external driving force along the axial direction of the housing 401 and has a tendency to slide, the collar 406 is rotatably sleeved on the outer circumference of the adjusting rod 405 through a bearing structure. While maintaining relative rotational freedom with the adjusting rod 405, the collar 406 can synchronously translate with the adjusting rod 405 in the horizontal direction. The collar 406 is fixedly connected to several adjusting racks 407, thereby driving all adjusting racks 407 to slide horizontally in the same direction. One end of each adjusting rack 407 is constrained in the corresponding guide rail on the inner wall of the housing 401 through a guide groove or limiting block structure, ensuring that it can only move along a preset horizontal trajectory. The other end of the adjusting rack 407 is machined with a precise rack segment, which is in constant mesh with the reversing gear 403.

[0042] When the adjusting rack 407 moves horizontally, its rack portion transmits the driving force to the reversing gear 403 meshing with it, forcing the reversing gear 403 to rotate around its axis. The reversing gear 403 is connected to the agitator 404 inside the housing 401 through a shaft, thereby converting the rotational motion of the gear into the deflection motion of the agitator 404. Since the displacement of each adjusting rack 407 is the same, and the specifications and number of teeth of all reversing gears 403 are consistent, each agitator 404 achieves completely synchronized rotation under the drive of the adjusting rack 407. The rotation angle α of each agitator 404 is geometrically strictly proportional to the displacement of the adjusting rack 407, and the value of the rotation angle α and the rotation direction of all agitators 404 are always consistent, thereby achieving coordinated control of the flow field direction.

[0043] Please see Figure 5 , Figure 6 and Figure 7 In a preferred embodiment of the present invention, the adjusting component 5 includes a sliding sleeve housing 501, a sliding table 502, a guide rod 504, a linear motor 505, and a linkage frame 506. The sliding table 502 is elastically slidably mounted on the sliding sleeve housing 501 in the horizontal direction. One end of the guide rod 504 is fixedly mounted on the main frame 101, and the other end of the guide rod 504 is elastically slidably mounted on the sliding sleeve housing 501. One end of the linear motor 505 is fixedly mounted on the sliding sleeve housing 501. 05 The other end is equipped with a linkage frame 506, which is movably connected to the slide table 502; the adjustment component 5 also includes a shaft frame 507, a sliding guide groove 508, a sliding pin shaft 509 and a bracket 510. One end of the shaft frame 507 is fixedly connected to the adjustment rod 405, and the other end of the shaft frame 507 is provided with a sliding guide groove 508. One end of the sliding pin shaft 509 is fixedly connected to the sliding sleeve housing 501 through the bracket 510, and the other end of the sliding pin shaft 509 is limited and slidably assembled in the sliding guide groove 508.

[0044] In practical application, the sliding sleeve housing 501 is mounted on the guide rod 504 in a vertical direction using an elastic sliding pair. Simultaneously, the slide table 502 moves laterally relative to the sliding sleeve housing 501 via a horizontal sliding pair. When the petroleum coke particles discharged from the discharge hopper 104 fall onto the bearing surface of the slide table 502, the total mass of the system consisting of the sliding sleeve housing 501 and the slide table 502 changes with the transient change in the mass of the accumulated petroleum coke material. The linear motor 505, under energized driving conditions, drives the linkage frame 506 to perform reciprocating linear motion, thereby causing the slide table 502 to periodically reciprocate horizontally. This continuously transports the petroleum coke material accumulated on the surface of the slide table 502 to the external discharge area. Within a unit of time, the amount of material on the slide table 502 increases. The material retention rate is directly affected by the discharge flow rate of the discharge hopper 104. Based on this effect, the system can dynamically generate a negative feedback adjustment signal by changing the material load on the slide table 502 in real time. This signal acts on the drive mechanism of the agitator 404, causing it to adjust its tilt angle around the rotating shaft. The change in the tilt angle of the agitator 404 directly modulates the flow rate and residence time of the petroleum coke material in the main channel 102, thereby achieving active flow control regulation of the feeding process. Through this closed-loop control system, the material transmission characteristics in the main channel 102 can be adaptively adjusted according to the instantaneous feed rate of the front discharge hopper 104, ultimately making the output material flow rate at the end of the slide table 502 tend to be dynamically stable, realizing autonomous balance and constant flow control in the petroleum coke material conveying process.

[0045] Furthermore, the adjusting component 5 also includes toothed surfaces 503. These toothed surfaces 503 are arrayed on the surface of the slide table 502 and face the discharge hopper 104. The toothed surfaces 503 of the slide table 502 are designed with oblique sawtooth patterns. When the slide table 502 slides horizontally into the sliding sleeve housing 501, the petroleum coke particles on the toothed surfaces 503 maintain their original spatial position due to the direction of the slide table's movement being opposite to the direction of the sawtooth inclination, and the toothed surfaces not effectively blocking the particles. They only move as a whole with the slide table. When the slide table 502 moves in the opposite direction, i.e. towards the sliding sleeve housing... When the body 501 slides externally, the toothed surface 503 of the inclined sawtooth pattern comes into contact with the petroleum coke particles. During the horizontal movement, the inclined surface of the sawtooth pattern generates a continuous thrust component on the particles, pushing the petroleum coke particles to gradually migrate away from the slide table 502 along the inclined direction of the sawtooth pattern. Through the reciprocating motion of the slide table 502, the above process is repeated, so that the petroleum coke components accumulated on the toothed surface 503 are continuously guided to the outside of the sliding sleeve housing 501, thereby realizing the continuous discharge of materials. This mechanism effectively avoids the accumulation and blockage of petroleum coke particles on the surface of the slide table, ensuring the smoothness and stability of the conveying process.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
