Description

Technical Field

[0001] This utility model relates to the field of prebaked anode production technology, specifically to a device for blending petroleum coke anodes. Background Technology

[0002] One of the two most important raw materials in the production of prebaked anodes is petroleum coke, a black or dark gray solid carbonaceous material mainly produced by the coking of crude oil at high temperatures. It is an important byproduct of petroleum refining and is characterized by high carbon content (usually exceeding 80%), low ash content, and low sulfur content.

[0003] With the continuous advancement of crude oil refining technology, the quality of petroleum coke for prebaked anode production has shown a gradual downward trend. In order to achieve full and effective utilization of resources and ensure that the produced prebaked anode products meet quality requirements, it is usually necessary to blend petroleum coke of different types, compositions, and particle sizes.

[0004] Currently, the blending of petroleum coke mainly relies on loader operations; however, this method has significant limitations. First, loader blending is inefficient. Second, loader blending struggles to achieve a completely uniform mixture of petroleum coke of different types, compositions, and particle sizes. Especially for petroleum coke of different particle sizes, loader blending rarely achieves ideal uniformity. This not only severely affects the quality stability of the petroleum coke mixture but also negatively impacts the subsequent production of prebaked anodes, thus hindering further improvements in product quality.

[0021] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0022] To facilitate understanding of the specific embodiments of this application, a coordinate system is now defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0023] Example 1 like Figure 1 ,like Figure 2 and Figure 3 As shown, a device for blending anode petroleum coke includes a raw material silo 1, a conveying mixer 2, a buffer silo 3, a conveyor 4, a first elevator 5, and a second elevator 6.

[0024] The number of raw material bins 1 is at least two, and the discharge ports of the raw material bins 1 are respectively connected to the inlet of the conveying mixer 2. A first control valve 21 is provided at the inlet of the conveying mixer 2. The discharge port of the conveying mixer 2 is connected to the upper inlet of the buffer bin 3 through a first elevator 5. A conveyor 4 is provided below the discharge port of the buffer bin 3, and a second control valve 31 is provided at the discharge port of the buffer bin 3. One end of the conveyor 4 is connected to the upper inlet of one of the raw material bins 1 through a second elevator 6.

[0025] In one specific implementation, the number of raw material silos 1 in this embodiment is three, and according to... Figure 1 In the coordinate system shown, the three raw material bins 1 are arranged in a straight line along the transverse direction. Each raw material bin 1 includes a raw material bin body 11 and a raw material bin frame 12 for supporting the raw material bin body 11. The conveying mixer 2 is located below the middle raw material bin 1, and the conveying direction of the conveying mixer 2 is along the front-to-back direction. The buffer bin 3 is located on the right side of the front end of the conveying mixer 2, and the conveying direction of the conveyor 4 is along the left-to-right direction. The first elevator 5 and the second elevator 6 are located between the conveying mixer 2 and the buffer bin 3, and are located on the front and rear sides of the conveyor 4, respectively. The inlet of the first elevator 5 is connected to the outlet of the conveying mixer 2 through a connecting pipe, and the outlet of the first elevator 5 is located above the buffer bin 3. The inlet of the second elevator 6 is located below the end of the conveyor 4 facing the conveying mixer 2, and the outlet of the second elevator 6 is located above the middle raw material bin 1.

[0026] Preferably, the conveying mixer 2 is a twin-shaft conveying mixer 2, and the conveyor 4 is a belt conveyor 4. The twin-shaft conveying mixer 2, the belt conveyor 4, the first elevator 5, and the second elevator 6 are all existing technologies and can be obtained by purchasing them externally. Their specific structures will not be described in detail here.

[0027] In one specific implementation, both the first control valve 21 and the second control valve 31 described in this embodiment are pneumatic slide gate valves. The pneumatic slide gate valves are controlled by a cylinder driving the valve plate to move horizontally. The pneumatic slide gate valves are existing technology and can be obtained through external purchase; therefore, their specific structure will not be described in detail here.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the feed inlet of the conveying mixer 2 is located at the rear end of the upper side of the conveying mixer 2, and the discharge outlet of the conveying mixer 2 is located at the front end of the lower side of the conveying mixer 2. The feed inlet of the conveying mixer 2 is connected and fixed to the lower connecting plate of the first control valve 21 by a flange connection. The discharge ports of the three raw material bins 1 are respectively connected to the manifold 7 by guide pipes 13, wherein the guide pipe 13 located in the middle raw material bin 1 is arranged vertically, and the guide pipes 13 located in the middle raw material bins on both sides are arranged obliquely. The lower end of the guide pipe 13 is connected to the upper end of the manifold 7 by a flange connection, and the lower end of the manifold 7 is connected and fixed to the upper connecting plate of the first control valve 21 by a flange connection.

[0029] Furthermore, to ensure the smooth flow of materials within raw material silo 1 and to prevent clumping and flow interruptions, such as... Figure 4 As shown, each of the raw material bins 1 is equipped with a vibrator 14 on its raw material bin body 11. The vibrator 14 is existing technology and can be obtained by purchasing it externally; its specific structure will not be described in detail here.

[0030] In one specific embodiment, the vibrator 14 described in this embodiment is detachably fixed to the conical guide section at the lower end of the raw material silo 11.

[0031] Furthermore, such as Figure 6 and Figure 7As shown, the buffer bin 3 is equipped with a secondary mixing unit 8. The secondary mixing unit 8 includes a mixing cone 811 that can rotate relative to the buffer bin 3 around its own axis and a driving component for driving the mixing cone 811 to rotate, with the larger end of the mixing cone 811 facing downwards. When material enters the buffer bin 3 through the first elevator 5, it falls onto the mixing cone 811 and spirals downwards as the mixing cone 811 rotates. In this way, the petroleum coke is further dispersed and secondary mixed when it enters the buffer bin 3. Through this dual mixing mechanism, various types of petroleum coke can achieve more uniform mixing, significantly improving the uniformity and consistency of the raw materials, and providing a high-quality raw material guarantee for the subsequent production of prebaked anodes.

[0032] As one specific implementation method, such as Figure 12 As shown, the secondary mixing unit 8 in this embodiment includes a rotating component 81, a fixed component 82, and a driving component. The fixed component 82 is detachably fixedly connected to the mixing chamber, the rotating component 81 is rotatably connected to the fixed component 82 via a bearing assembly, and the driving component drives the rotating component 81 to rotate relative to the fixed component 82 around its own axis.

[0033] The bearing assembly described herein employs a thrust bearing 83. In one specific embodiment, the thrust bearing 83 described in this example is a thrust cylindrical roller bearing.

[0034] like Figure 7 , Figure 8 , Figure 11 and Figure 12As shown, the fixing component 82 includes a base frame 821.

Exemplarily, the base frame 821 includes a plurality of radially arranged support beams 8211 and connecting beams 8212 for connecting the support beams 8211. The connecting beams 8212 are located in the middle of the radial structure formed by the support beams 8211 and form a frame structure. A fixing plate 8213 is fixedly provided on the lower side of the end of the support beam 8211 by welding. The fixing plate 8213 is fixedly connected to the mounting plate 32 by first screws. The base frame 821 is provided with a fixing cylinder 822, which includes a fixing cylinder body 8221. A seat plate 8222, coaxially arranged with the fixing cylinder body 8221, is fixedly mounted on the lower end of the fixing cylinder body 8221 by welding. Preferably, the seat plate 8222 has a circular ring structure. A plurality of second screws are evenly distributed along the circumferential direction on the outer side of the fixing cylinder body 8221 between the seat plate 8222 and the base frame 821. The fixing cylinder 822 is fixedly connected to the base frame 821 by the second screws. A first support plate 8223, extending radially inward and having a circular ring structure, is provided on the inner wall of the fixing cylinder body 8221. The outer side of the first support plate 8223 is fixedly connected to the inner wall of the fixing cylinder body 8221 by welding. A plurality of second stiffening plates 8224 are evenly distributed along the circumferential direction on the lower side of the first support plate 8223. The fixed cylinder 8221 and the first support plate 8223 together form a seat hole for accommodating the seat ring of the thrust bearing 83.

[0035] like Figure 9 , Figure 10 , Figure 13 , Figure 14 and Figure 15As shown, the rotating component 81 includes, from top to bottom, a mixing cone 811 and a support cylinder 812. The mixing cone 811 has a conical structure with its large end facing downwards. The support cylinder 812 includes a support cylinder body 8121. A second support plate 8122 with a radially outwardly extending annular structure is provided on the outer wall of the support cylinder 812. The inner side of the second support plate 8122 is fixedly connected to the support cylinder body 8121 by welding. A plurality of third ribs 8123 are evenly distributed along the circumference between the upper side of the second support plate 8122 and the outer wall of the support cylinder body 8121. The lower end of the support cylinder body 8121 is inserted into the shaft ring of the thrust bearing 83, and the second support plate 8122 is pressed against the shaft ring of the thrust bearing 83.

[0036] Furthermore, to improve the structural strength of the mixing cone 811 and prevent deformation under material impact, a skeleton 813 is provided on the inner surface of the mixing cone 811. The skeleton 813 includes a core cylinder 8131 in a cylindrical structure, which is coaxially arranged with the mixing cone 811, and the upper end of the core cylinder 8131 is fixedly connected to the mixing cone 811 by welding. A plurality of ribs 8132 are evenly distributed along the circumference on the outer cylindrical surface of the core cylinder 8131. The end of the rib 8132 facing the core cylinder 8131 is fixedly connected to the core cylinder 8131 by welding, the upper side of the rib 8132 is fixedly connected to the inner surface of the mixing cone 811 by welding, and the rib 8132 extends outward to the edge of the mixing cone 811. Correspondingly, the upper end of the support cylinder 8121 is provided with a plurality of slots 8124 corresponding one-to-one with the ribs 8132 of the skeleton 813. The ribs 8132 are inserted into the corresponding slots 8124, and the upper end face of the support cylinder 8121 abuts against the inner side of the mixing cone 811.

[0037] Here, the support cylinder 8121 can be fixedly connected to the frame 813 and the mixing cone 811 by a non-removable method such as welding, or it can be fixedly connected to the frame 813 and the mixing cone 811 by a detachable method. Preferably, the support cylinder 8121 is fixedly connected to the frame 813 and the mixing cone 811 by a detachable method.

[0038] In one specific embodiment, the lower end of the core cylinder 8131 is provided with a sealing plate 8133. A tension rod 814 extending downwards perpendicular to the sealing plate 8133 is provided on the sealing plate 8133, and the tension rod 814 is coaxially arranged with the core cylinder 8131. A connecting inner plate 8125 is provided inside the supporting cylinder 8121. The lower end of the tension rod 814 passes through the connecting inner plate 8125 and extends to the lower side of the connecting inner plate 8125. The connecting inner plate 8125 is provided with a clearance hole allowing the tension rod 814 to pass through. A locking nut 8141 is provided on the tension rod 814 located on the lower side of the connecting inner plate 8125.

[0039] Furthermore, a connecting cylinder 8126 is provided on the upper side of the connecting inner plate 8125, coaxially arranged with the clearance hole, and the inner diameter of the connecting cylinder 8126 is equal to the diameter of the clearance hole. A plurality of radially arranged fourth stiffening plates 8127 are evenly distributed between the connecting cylinder 8126 and the supporting cylinder 8121. This effectively enhances the structural strength of the supporting cylinder 812 itself, thereby improving the structural rigidity of the entire rotating component 81, enabling it to withstand greater loads.

[0040] like Figure 7 , Figure 9 , Figure 12 and Figure 13 As shown, the driving component includes an internal gear ring 841 disposed in the fixed cylinder 822, a gear 842 meshing with the internal gear ring 841, and a drive motor 843 for driving the gear 842 to rotate on the support cylinder 812.

[0041] In one specific embodiment, a motor plate 8431 is provided at the lower end of the support cylinder 8121, and both ends of the motor plate 8431 are detachably fixedly connected to the support cylinder 8121. For example, ear plates 8128 extending inward are provided on both sides of the support cylinder 8121, and both ends of the motor plate 8431 are connected and fixed to the ear plates 8128 by bolt assemblies. The drive motor 843 is fixedly mounted on the upper side of the motor plate 8431 by a third screw. A rotating shaft 844 is provided on the motor plate 8431, and a gear 842 is provided on the lower end of the rotating shaft 844.

[0043] Furthermore, a plurality of radially arranged baffles 815 are evenly distributed on the upper side of the mixing cone 811 along the circumferential direction. By setting the baffles 815, the uniformity of mixing can be further improved.

[0044] When the number of raw materials to be blended is three or fewer: The petroleum coke grab bucket sequentially feeds the raw materials into the raw material bin 1. At this time, the vibrator 14 is activated to facilitate the falling of the raw materials, and the twin-shaft conveyor mixer 2 is also activated simultaneously, with the first control valve 21 opening. The raw materials enter the conveyor mixer 2 through the feed inlet, and the twin mixing shafts of the conveyor mixer 2 begin to operate, performing comprehensive mixing of the various raw materials. During the mixing process, not only are the different raw materials thoroughly mixed, but large particles of petroleum coke are also effectively crushed, ensuring the uniformity of the raw materials. After mixing, the raw materials are sent to the first elevator 5 through the discharge outlet, and the first elevator 5 lifts the raw materials to the top of the buffer bin 3. When the raw materials enter the buffer bin 3, the slowly rotating mixing cone 811 inside the buffer bin 3 plays a role in secondary mixing of the raw materials. After two rounds of blending and mixing, the raw materials have fully met the requirements for petroleum coke blending. At this time, the second control valve 31 at the bottom of the buffer bin 3 opens, and the conveyor 4 starts, thereby smoothly conveying the mixed petroleum coke mixture to the discharge side for subsequent calcination operations.

[0045] When more than three types of raw materials are being blended, the three types of petroleum coke raw materials are first placed into the three raw material bins 1 respectively through petroleum coke grab buckets. At this time, the vibrator 14 and the conveying mixer 2 are started, and the first control valve 21 is opened simultaneously. The raw materials enter the conveying mixer 2 through the feed inlet, and the double stirring shafts inside the conveying mixer 2 begin to rotate, stirring the raw materials. After stirring is completed, the raw materials are sent to the first elevator 5 through the discharge outlet, and the first elevator 5 lifts the raw materials to the top of the buffer bin 3. When the raw materials enter the buffer bin 3, the slowly rotating mixing cone 811 inside the buffer bin 3 performs secondary mixing on the raw materials. Subsequently, the second control valve 31 at the bottom of the buffer bin 3 is opened, and the raw materials are conveyed to the second elevator 6 through the conveyor 4 and lifted into the middle raw material bin 1. Then, the petroleum coke raw materials that need to be blended further are placed into the raw material bins 1 on both sides through petroleum coke grab buckets, and the blending and batching are carried out according to the previous mixing steps. The above stirring, lifting, and mixing operations are repeated until all petroleum coke raw materials are completely and evenly mixed. Finally, the mixed petroleum coke mixture is conveyed to the feeding side by conveyor 4, ready for subsequent calcination operations.

The upper end of the central shaft is fixedly connected to the mixing cone 811. The fixing component 82 of the secondary mixing unit 8 includes a base frame 821, with the central shaft rotatably connected to the base frame 821 via a bearing assembly. The driving component includes a drive motor 843 mounted on the base frame 821, and the power output shaft of the drive motor 843 is connected to the central shaft via a transmission mechanism.

[0047] The transmission mechanism can employ gear 842. That is, a driven gear 842 is provided on the central shaft, the power output shaft of the drive motor 843 faces upward or downward, and a driving gear 842 that meshes with the driven gear 842 is provided on the power output shaft of the drive motor 843.

Specifically, a worm gear is mounted on the central shaft, and a worm gear meshing with the worm gear is mounted on one side of the worm gear. Both ends of the worm gear are rotatably connected to the base frame 821 via bearing assemblies. The drive motor 843 is mounted on the base frame 821, and the power output end of the drive motor 843 is connected to the worm gear via a coupling.
