[0003] During use, the existing petroleum coke blending device usually directly puts the petroleum coke and other blending materials into the high-efficiency petroleum coke blending system for mixing.

When the petroleum coke and blending material particles enter the pre-mixing barrel, they will first collide with the impeller fan of the pre-mixing barrel, thereby causing the impeller fan to rotate. The rotating impeller fan makes the petroleum coke and blending materials evenly distributed in various positions in the pre-mixing barrel, and then the petroleum coke and blending material particles will be dispersed through the feed plate assembly. At the same time, the feed plate assembly also slows down the petroleum coke and blending material particles in the process of passing through the feed plate assembly, so that large particles and small particles in the petroleum coke and blending material particles can pass through the feed plate assembly at the same time, and the petroleum coke and blending material particles passing through the feed plate assembly will collide with the first mixing rod assembly, thereby causing the first mixing rod assembly to rotate, and then the first mixing rod assembly is used to achieve preliminary mixing of the petroleum coke and blending material particles; Drying of pre-mixed petroleum coke and blended materials: The preliminarily mixed particles of petroleum coke and blended materials will enter the drying box of the drying mechanism for drying, and the preliminarily mixed particles of petroleum coke and blended materials will enter different areas of the drying box for simultaneous drying.

The petroleum coke and the blending materials are finally fully mixed: when the dried petroleum coke and the blending materials enter the mixing barrel of the mixing mechanism, the second mixing rod assembly in the mixing barrel can be used to fully mix the petroleum coke and the blending materials, and the fan transmits the outside air sucked by the fan to the cooling circles at various positions of the mixing barrel through the air supply pipe and the diversion pipe, and the outside air sprayed by the cooling circle will increase the internal air pressure of the mixing barrel, so that the outside air is discharged through the air relief valve, realizing the circulation of air in the mixing barrel, and achieving full mixing of the petroleum coke and the blending materials entering the mixing barrel while cooling them down, and the petroleum coke and the blending materials that have completed mixing will be discharged through the discharge port.

[0014] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The efficient petroleum coke blending system can realize the preliminary mixing of the petroleum coke and the blending materials according to their sizes and shapes into the premixing barrel in sequence through the feed assembly, the feed plate assembly and the first mixing rod assembly in the feed premixing mechanism. The feed assembly uses magnetic balls with different magnetic properties to adsorb the elastic material blocking plate, thereby blocking the petroleum coke or blending materials entering the current feed barrel. When the petroleum coke or blending materials in the feed barrel reach a certain amount, the gravity generated will cause the magnetic balls to be unable to adsorb the elastic material blocking plate, thereby This causes the elastic material resistance plate to open, allowing the petroleum coke or admixture to enter the premixing barrel. The dividing plate assembly in the premixing barrel can reduce the speed of the petroleum coke or admixture entering the premixing barrel in advance, so that the petroleum coke and the admixture enter the premixing barrel in sequence according to their size and shape, and can be mixed by the first mixing rod assembly at the same time. Through material division and premixing, it can be ensured that different materials enter in a specific order, thereby improving the uniformity of mixing, optimizing the mixing process of petroleum coke and admixtures, and improving the mixing uniformity and material properties of petroleum coke and admixtures.

[0015] 2. The efficient petroleum coke blending system can realize the partition drying of the petroleum coke and blending materials entering the drying box after the initial mixing through the partition plates and the drying and stirring components in the drying mechanism, so as to avoid the petroleum coke and blending materials piling up in large quantities, which would cause the mixture of petroleum coke and blending materials to be over-dried on the outside and unable to be dried on the inside. Partition drying can ensure that each part of the material is heated evenly, avoid the problem of excessive drying on the outside and moisture on the inside, and improve the drying efficiency. At the same time, drying the petroleum coke and blending materials can remove excess moisture, avoid unnecessary chemical reactions in the subsequent full mixing process, and ensure stable material performance.

[0016] 3. The efficient petroleum coke blending system can achieve the final thorough mixing of the petroleum coke and blending material mixture after preliminary mixing and drying through the fixed frame assembly and the second mixing rod assembly in the mixing mechanism, wherein the second mixing rod assembly achieves thorough mixing after preliminary mixing through rapid rotation, and the combination of the petroleum coke and blending material mixture after preliminary mixing and drying in the fixed frame assembly and the second mixing rod assembly can ensure that the materials are more uniform during the mixing process, avoiding the phenomenon of lighter materials floating on the surface and forming stratification due to rapid stirring.

The shunt pipe 461 has an input end and multiple output ends. The output ends of the shunt pipe 461 correspond to the number of the gas injection blocks 46 and are connected. A fan 48 is fixedly connected to the side of the base 1, and the output end of the fan 48 is fixedly connected with an air supply pipe 481. The air supply pipe 481 is fixedly connected to the input end of the shunt pipe 461 away from the fan 48, and a discharge port 47 is fixedly connected to the bottom of the mixing barrel 41.

[0037] By utilizing the electric rotating column 441 in the second mixing rod assembly 44 to drive the rotation of the double connecting rod 443 and the convex ball 445, the pre-mixed petroleum coke and the admixtures can be fully mixed, and the fan 48 can cool the fully mixed petroleum coke and the admixtures through the cooling ring 42, and the air relief valve 45 discharges the heat generated during the cooling from the mixing barrel 41.

[0038] The operating principle of this embodiment is as follows: Step 1: First, put petroleum coke or admixtures (such as coal, mineral additives, petroleum asphalt, etc., and this equipment is only suitable for solid granular admixtures, and the proportion of petroleum coke or admixtures is assumed to have been completed by default. At the same time, it is assumed that the material with a relatively small proportion in the petroleum coke or admixtures is relatively easy to flow due to the small gap between each other under the same volume, while the irregular and large particles are relatively difficult to flow due to the large gap between each other) into the feed assembly 28 according to their number. The number of feed assemblies 28 is determined by the type of admixtures required. When the petroleum coke or admixtures enter the feed barrel 281 in the feed assembly 28, the elastic material blocking plate 282 The petroleum coke or the admixture will be blocked, and the elastic material blocking disk 282 is composed of a fixed ring and a circle formed by a plurality of fan-shaped plates, and each fan-shaped plate is connected to the fixed ring by an elastic hinge, so the circle formed by the fan-shaped plates will form a closed circle in the fixed ring under the action of the elastic hinge (at this time, the closed circle formed by the fan-shaped plates is not affected by the weight of the petroleum coke or the admixture), and a magnetic ball 283 is arranged above the elastic material blocking disk 282, so as to adsorb the closed circle formed by the plurality of fan-shaped plates in the elastic material blocking disk 282 (the magnetic force of the magnetic ball 283 in each feeding component 28 is the same), thereby enhancing the weight required for the closed circle to be separated, and the magnetic ball 283 in each feeding component 28 is used to separate the closed circle. 3 produces the same suction force on the elastic material resistance disk 282, so the pressure entering each pre-mixing barrel 21 to overcome the adsorption of the magnetic ball 283 on the elastic material resistance disk 282 is the same, so that the amount of different proportions of petroleum coke or admixtures to overcome the adsorption of the magnetic ball 283 on the closed circle in the elastic material resistance disk 282 is also different. Because the size and shape of the petroleum coke or admixture are different, the petroleum coke or admixture with higher density and larger particles will cause greater pressure on the elastic material resistance disk 282 at the same volume, thereby overcoming the adsorption of the magnetic ball 283 on the closed circle formed by the multiple fan-shaped plates in the elastic material resistance disk 282 in advance, and then causing the fan-shaped plates to form a closed circle to open, resulting in a higher density and The petroleum coke or admixture with larger particles will enter the premixing barrel 21 first, while the petroleum coke or admixture with a smaller size and shape than the former will need a larger amount to overcome the adsorption of the magnetic ball 283 on the elastic material blocking disk 282, so that the petroleum coke or admixture entering the premixing barrel 21 enters in the order of the petroleum coke volume proportion from small to large. The petroleum coke or admixture is added and mixed in the order of the petroleum coke volume from small to large, which can improve the mixing uniformity and efficiency, improve the fluidity, control the reactivity, reduce the equipment wear, and optimize the physical and chemical properties of the final product. This method ensures that the small proportion of additives can be evenly dispersed, avoids local uneven concentration, and thus improves the overall mixing quality; Among them, when the petroleum coke and the admixture enter the premixing barrel 21 in sequence through the feeding assembly 28, the petroleum coke and the admixture will first contact the impeller fan 23. Since the process of the petroleum coke and the admixture entering the premixing barrel 21 from the feeding assembly 28 is a free fall motion, the petroleum coke and the admixture have a certain power when entering the premixing barrel 21, causing the impeller fan 23 to rotate when the petroleum coke and the admixture contact the impeller fan 23. Because when the petroleum coke and the admixture contact the impeller fan 23, the kinetic energy is converted into impact force, so that the impeller fan 23 is pushed, thereby causing it to rotate. As the impeller fan 23 rotates, the impeller fan 23 can guide and disperse the petroleum coke and the admixture that have just entered the premixing barrel 21, so that it can be combined with the subsequent distribution plate assembly 24, the first mixing rod assembly 26 and the pre-stirring rod 2 in the premixing barrel 21. 7 Full contact promotes the effect of uniform dispersion of materials. After being dispersed by the impeller fan 23, the petroleum coke and the admixture will contact the distribution plate assembly 24, and the distribution plate assembly 24 uses the annular net composed of the connecting rod 242 and the annular ring 243 to achieve deceleration of the petroleum coke and the admixture that preferentially enter the premixing barrel 21, because the design of the annular net can increase the contact area and friction between the petroleum coke and the admixture (that is, the time required for large particles and large density to pass through the annular ring 243 is long), so that the flow speed is slowed down. Therefore, by deceleration, the interval time of petroleum coke and admixture with inconsistent size and shape entering the first mixing rod assembly 26 for pre-mixing treatment can be shortened (the interval time of petroleum coke and admixture with inconsistent size and shape passing through the annular ring 243 does not exceed 2 seconds), so that they can be better distributed and evenly mixed when entering the first mixing rod assembly 26; The petroleum coke and the blending material passing through the annular ring 243 will contact the first mixing rod assembly 26, and the first mixing rod assembly 26 can pre-mix the petroleum coke and the blending material entering therein, so that the petroleum coke and the blending material can be simply mixed in the pre-mixing barrel 21. The first mixing rod assembly 26 alternately arranges the catching pieces 262 and the mixing pieces 263 in the first fixed rod 261, and the force generated by the petroleum coke and the blending material when they fall and their own weight will act on the catching pieces 262 and the mixing pieces 263, so that the first mixing rod assembly 26 rotates; The material-catching sheet 262 and the material-mixing sheet 263 can realize the simultaneous capture, collection, mixing and dispersion of the petroleum coke and the admixtures that need to be premixed, because a grid frame 264 is provided in the material-catching sheet 262, and the grid frame 264 can realize the capture and collection of the petroleum coke and the admixtures, because the grid frame 264 has a notch structure, when the petroleum coke and the admixtures are in contact with the grid frame 264, they will be blocked by the grid frame 264 and gathered in the notch thereof, and the notch of the grid frame 264 can be designed according to the particle size of the petroleum coke and the admixtures, so that the petroleum coke and the admixtures can be effectively captured without excessively hindering the mixing and dispersion effect of the mixing sheet 263, and the mixing sheet 263 is provided with a plurality of mixing structures 2 65. The mixing structure 265 can achieve the dispersing and mixing effect on the petroleum coke and the admixtures by using the first mixing inclined piece 2652 and the conical head 2653 therein, because the first mixing inclined piece 2652 can change the flow direction of the material, so that the petroleum coke and the admixtures generate turbulence during the flow, thereby breaking the original flow state of the material and achieving the dispersing and mixing effect. The conical head 2653 has a unique shape. On the one hand, it can guide the material to flow in different directions and increase the collision and friction between the materials. On the other hand, the tip of the conical head 2653 can be inserted into the material to further destroy the agglomeration state of the material, promote the uniform mixing of the petroleum coke and the admixtures, and improve the efficiency and uniformity of premixing. Among them, the premixed petroleum coke and admixtures (hereinafter referred to as the premixed petroleum coke and admixtures) will contact the pre-mixing rods 27 in different directions, and the pre-mixing rods 27 can guide and divert the flow of the mixture, thereby avoiding the mixture from clumping. This is because the pre-mixing rod 27 is composed of three parts, namely, a cylinder, a cone and a sphere, which are alternately arranged in sequence, and the cylinder, cone and sphere can provide different flow paths during the mixing process, thereby breaking the aggregation state of the material and making it more evenly dispersed. At the same time, the alternating arrangement of these shapes (cylinders, cones and spheres) can change the flow direction and speed of the fluid, promote the mutual collision and mixing of the mixture in the flow, reduce the adhesion between particles, and further achieve the premixing effect.

[0039] Step 2: After the pre-mixing, the mixture will pass through the porous plate 29 and enter the drying box 31 of the drying mechanism 3, and the drying mechanism 3 can dry the mixture to remove the moisture in the mixture. Drying the mixture can avoid the adhesion between the particles of the mixture before they are fully mixed, thereby forming lumps and affecting the uniformity of the mixture. After drying, the contact between the particles is freer, which helps to achieve more uniform mixing; The four partition plates 33 divide the drying box 31 into four independent areas with the heat-conducting column 32 as the center, and the mixture in the pre-mixing barrel 21 is evenly distributed in the four independent areas through the porous plate 29, and the heat-conducting column 32 generates heat by using the heating rod 37 arranged inside it, and evenly transmits the heat generated by the heating rod 37 to each area through the heat-conducting rod 34, so as to realize the drying of the mixture in each area. At the same time, in order to avoid the phenomenon that the mixture is excessively dried outside and cannot be dried inside due to the large amount of mixture piled up together during the drying process, a drying stirring component 35 for stirring and turning the mixture in the drying state is arranged in each area, and the drying stirring component 35 is used to stir and turn the mixture in the drying state. The built-in motor provided inside the rotating column 351 is used to rotate the rotating column 351. As the rotating column 351 rotates, the rotating rod 352 and the stirring tilting piece 353 provided in the rotating column 351 also rotate accordingly, thereby achieving stirring and flipping of the mixture in a drying state. At the same time, since the stirring tilting pieces 353 above and below the rotating column 351 are tilted in opposite directions, the stirring tilting pieces 353 in opposite directions can effectively break the dead corners in the material, promote the flow of the material, and ensure that each part can participate in the drying process. At the same time, the stirring tilting pieces 353 in different directions can also generate convection and shear force during the stirring process, so that the mixture can be more fully exchanged between different layers, thereby improving the mixing uniformity.

[0040] Among them, since each area in each drying box 31 is provided with a humidity sensor, when the humidity sensor detects that the mixture in the current area has been dried, it will send a signal to the controller (the controller is prior art, so it is not drawn in the figure), and when the controller receives the signal sent by the humidity sensor in the corresponding area, the controller will send a signal to the corresponding discharge component 36 in its area, so that the electric telescopic rod 361 in the discharge component 36 at the corresponding position is extended, and as the electric telescopic rod 361 is extended, the connecting block 362 located under the electric telescopic rod 361 also drops synchronously. When the connecting block 362 drops, it will drive the slider 364 to slide out of the discharge square hole in the corresponding area of ​​the drying box 31 synchronously through the connecting arm 363, so that the slider 364 loses the blockage of the discharge square hole, so that the mixture that has been dried in each area can be quickly discharged, thereby avoiding excessive drying of the mixture.

[0041] Step 3: The mixture after premixing and drying will enter the mixing mechanism 4 from the drying box 31 for final mixing. When the mixture enters the mixing barrel 41 in the mixing mechanism 4, the fan 48 starts to start synchronously. When the fan 48 starts, it will transmit the outside air to the shunt pipe 461 through the air delivery pipe 481, and the shunt pipe 461 will further transmit the outside air to the gas injection blocks 46 at various positions. Since the gas injection block 46 is connected to the cooling ring 42, the outside air will be transmitted to the inside of the mixing barrel 41 through the cooling ring 42, so as to cool down the fully mixed mixture in the mixing barrel 41. As a result, the outside air continues to enter the mixing barrel 41, causing the pressure in the mixing barrel 41 to increase. Therefore, excessive outside air will drive the heat of the mixture during drying to be discharged from the air release valve 45, thereby realizing heat exchange, and cooling helps to reduce the fluidity of the mixture, prevent the materials from sticking or agglomerating due to excessive temperature, thereby maintaining the independence of the particles. Among them, while the cooling circle 42 in the mixing mechanism 4 is cooling the mixture, the second mixing rod assembly 44 also starts to perform the final mixing of the mixture. The second mixing rod assembly 44 uses the rotating electric rotating column 441 therein to drive the double connecting rod 443 and the second mixing inclined and side convex balls 445 arranged on both sides of the double connecting rod 443 to rotate, thereby achieving the final mixing of the mixture. Because of the double connecting rod 443 and the inclined surface design, the mixture can be stirred from multiple directions and the mixture can produce a rotating and inclined movement direction. At the same time, the design of the double connecting rod 443 can ensure that the agitator contacts every part of the mixture, reducing dead angles, and the shear force generated by the rotating and tilting movement mode helps to break the material agglomeration and thus complete the final mixing of the mixture.

[0042] A blending process for efficient petroleum coke blending, the blending process includes: pre-mixing of petroleum coke and blending materials, drying of the pre-mixed petroleum coke and blending materials, and final full mixing of the petroleum coke and blending materials, specifically comprising the following steps: Premixing of petroleum coke and blending materials: First, the petroleum coke and blending materials are placed in separate feed components 28, so that the petroleum coke and blending material particles of the same volume in each feed component 28 enter the premixing barrel 21 in sequence according to the size of the petroleum coke and blending material particles. When the petroleum coke and blending material particles enter the premixing barrel 21, they will first collide with the impeller fan 23 of the premixing barrel 21, thereby causing the impeller fan 23 to rotate. The rotating impeller fan 23 makes the petroleum coke and blending materials evenly distributed in various positions in the premixing barrel 21, and then the petroleum coke and blending materials are The mixed material particles will be dispersed through the distribution plate assembly 24. At the same time, the distribution plate assembly 24 also slows down the petroleum coke and mixed material particles during the process of passing through the distribution plate assembly 24, so that large particles and small particles in the petroleum coke and mixed material particles can pass through the distribution plate assembly 24 at the same time. The petroleum coke and mixed material particles passing through the distribution plate assembly 24 will collide with the first mixing rod assembly 26, thereby causing the first mixing rod assembly 26 to rotate, and then the petroleum coke and mixed material particles are initially mixed through the first mixing rod assembly 26. Drying of pre-mixed petroleum coke and blended materials: the preliminarily mixed particles of petroleum coke and blended materials enter the drying box 31 of the drying mechanism 3 for drying, and the preliminarily mixed particles of petroleum coke and blended materials enter different areas of the drying box 31 for simultaneous drying, and in order to make the particles of petroleum coke and blended materials in each area evenly heated, a drying and stirring assembly 35 for stirring and drying the particles of petroleum coke and blended materials is provided in each area, and a discharge assembly 36 in each area discharges the dried particles of petroleum coke and blended materials to enter the mixing mechanism 4; The petroleum coke and the blending materials are finally fully mixed: when the dried petroleum coke and the blending materials enter the mixing barrel 41 of the mixing mechanism 4, the second mixing rod assembly 44 in the mixing barrel 41 can be used to fully mix the petroleum coke and the blending materials, and the fan 48 transmits the outside air sucked by the fan 48 to the cooling circle 42 at various positions of the mixing barrel 41 through the air supply pipe 481 and the diversion pipe 461, and the outside air sprayed by the cooling circle 42 will increase the internal air pressure of the mixing barrel 41, so that the outside air is discharged through the air relief valve 45, realizing the circulation of air in the mixing barrel 41, and achieving full mixing of the petroleum coke and the blending materials entering the mixing barrel 41 while cooling them, and the petroleum coke and the blending materials that have completed mixing will be discharged through the discharge port 47.

The outside air sprayed by the cooling ring (42) will increase the internal air pressure of the mixing barrel (41), so that the outside air is discharged through the air release valve (45), realizing the circulation of air in the mixing barrel (41), and achieving full mixing of the petroleum coke and the blending materials entering the mixing barrel (41) while cooling them down. The petroleum coke and the blending materials that have completed mixing will be discharged through the discharge port (47).
