Description

Technical Field

[0001] This invention relates to the field of green anode manufacturing technology, and in particular to a precise batching device for calcined coke powder used in green anode manufacturing. Background Technology

[0002] The raw material for calcined coke is petroleum coke (a black solid residue produced during petroleum refining, mainly composed of fixed carbon (approximately 85%–90%)). Petroleum coke needs to be calcined at high temperatures (1200–1450℃) in a furnace to remove volatiles, moisture, and sulfur, while simultaneously making the carbon structure denser and more stable, improving its electrical conductivity, thermal conductivity, and mechanical strength. The calcined petroleum coke (i.e., "calcined coke") is then crushed, sieved, and ground to obtain calcined coke powder of different particle sizes. Calcined coke powder is the basic raw material for green anode manufacturing. Its batching process must strictly adhere to the green anode production formula requirements. Calcined coke powder of different particle sizes is stored separately and then precisely metered and mixed in proportion using specialized equipment. Currently, most calcined coke powder batching devices in the industry adopt a step-by-step mixing mode, that is, the different particle sizes of calcined coke powder are first mixed in a premixing tank before being transported to subsequent equipment for adding binders.

[0003] However, existing step-mixing calcined coke powder batching devices have the following technical defects that urgently need to be addressed in practical applications: On the one hand, when calcined coke powder is mixed in the premixing tank, static electricity is easily generated due to friction between material particles and between the material and the inner wall of the tank. The statically charged powder particles will attract each other due to electrostatic attraction, first forming micro agglomerates. These micro agglomerates will continuously collide and gather during the mixing process, while adsorbing surrounding powder particles, gradually forming larger clumps, resulting in uneven mixing. At the same time, electrostatic adsorption will also cause the powder to adhere to the inner wall of the premixing tank and the surface of the stirring components, causing material accumulation. On the other hand, calcined coke powder added to the premixing tank from the previous process is prone to clumping due to factors such as compression during storage and transportation. Existing premixing tanks cannot effectively break up clumps by simply stirring, resulting in calcined coke powder of different particle sizes not being fully and uniformly mixed.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a precise batching device for calcined coke powder used in the manufacture of green anodes, so as to overcome the shortcomings in current practical applications. Summary of the Invention

[0005] The purpose of this invention is to provide a precise batching device for calcined coke powder used in the manufacture of green anodes, thereby addressing the problems mentioned in the background art.

A gear is fixedly sleeved on the outer wall of the drive shaft, and the gear and gear are meshed. A conveying assembly is provided inside the premixing tank. The conveying assembly and the drive shaft are connected in cooperation.

[0008] A further technical solution is provided, wherein an intercepting mesh plate is slidably connected inside the premixing tank, and the intercepting mesh plate is slidably connected to the stirring plate. A reciprocating component is provided between the intercepting mesh plate and the rotating shaft. A receiving ring is fixedly connected to the outer wall of the conveying component, and a dispersing component is provided on the receiving ring.

[0009] A further technical solution includes a conveying assembly comprising support plates, a conveying cylinder, spiral blades, a connecting rod, a fixing plate, and a discharge port; multiple support plates are fixedly connected to the bottom of the premix tank, and a conveying cylinder is fixedly connected between the multiple support plates; a fixing plate is fixedly connected to the inner wall of the conveying cylinder, and a connecting rod is rotatably connected to the inner wall of the fixing plate; the upper end of the connecting rod is fixedly connected to the drive shaft; spiral blades are wound around the outer wall of the connecting rod; the outer wall of the conveying cylinder is fixedly connected to a receiving ring; and multiple discharge ports are also provided on the outer wall of the conveying cylinder, with the discharge ports positioned between the receiving ring and the fixing plate.

[0010] A further technical solution includes a second receiving groove, a sliding groove, a fixed roller, a curved groove, a second guide rod, a second slider, and a rotating plate. A symmetrical second receiving groove is provided on the first receiving plate. A sliding groove is provided at the bottom of each second receiving groove. A fixed roller is fixedly sleeved on the outer wall of the rotating shaft. A curved groove is provided on the fixed roller.

The ion wind is used to remove static electricity and break up material agglomeration and adhesion. The stirring plate is used to promote uniform mixing. 2. The material at the bottom of the premix tank is conveyed to the top of the intercepting screen plate by the conveying component. The reciprocating component drives the intercepting screen plate to move up and down, thereby causing the material on the intercepting screen plate to vibrate. This ensures that the material that meets the requirements passes through the intercepting screen plate and reaches the lower position. The dispersing component disperses the material on the intercepting screen plate, thereby forming a cycle and further improving the mixing efficiency and uniformity. 3. The reciprocating component drives the intercepting mesh plate to move up and down in an oscillating motion. By adjusting the lifting and lowering of the intercepting mesh plate, the interaction force between it and the dispersing component can be gradually changed, avoiding particle size imbalance caused by excessive crushing and ensuring accurate material proportions.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0019] like Figures 1-9As shown, this embodiment of the invention provides a precise batching device for calcined coke powder used in the manufacture of green anodes, including a weighing silo 1. The weighing silo 1 includes a premixing tank 2 and a top cover 3. The top cover 3 is fitted onto the top of the premixing tank 2. A feeding hopper is provided on the side wall of the premixing tank 2. A drive groove is formed on the inner wall of the top cover 3. A circular rack 20 is fixedly connected in the drive groove. A receiving plate 17 is rotatably connected inside the top cover 3. A second motor (not shown in the figure) is fixedly connected to the receiving plate 17, and the gear at the end of the second motor meshes with the circular rack 20. A plurality of evenly distributed stirring plates 18 are fixedly connected to the lower end of the receiving plate 17. The side wall of the premixing tank 2 has... The premix tank 2 has a negative pressure port 4, through which a negative pressure device is connected. A dust removal device is also installed on the negative pressure device. A discharge port 5 is fixedly connected to the bottom end of the premix tank 2. A placement groove (not marked in the figure) is opened on the bottom outer wall of the premix tank 2. Multiple covers 61 are fixedly connected in the placement groove. An air chamber 63 is fixedly connected to the inner wall of each cover 61, and the air chamber 63 is attached to the inner wall of the placement groove. An air port 62 is fixedly connected to each air chamber 63. The other end of the air port 62 passes through the cover 61 and is connected to an ion fan through a conveying pipe. The ion fan injects ion air into the premix tank 2, thereby neutralizing the positive and negative charges in the premix tank 2 and effectively reducing electrostatic adsorption.

[0020] It is understandable that a pump body is also installed on the conveying pipe between the cover 61 and the ion blower to ensure that the ion wind generated by the ion blower can enter the premix tank 2; the weighing hopper 1 is existing technology and has a weighing function.

[0021] Specifically, calcined coke powders of different particle sizes are sequentially added to the premixing tank 2 through the feeding hopper. The weighing module on the weighing hopper 1 identifies the amount of each type of calcined coke powder added. The combination of a negative pressure device and a dust removal device effectively reduces dust leakage during the batching process and effectively reduces the dust concentration in the mixing chamber. A small amount of dust collected by the dust collector is added to the next process to ensure that the amount of material before and after batching is the same. The receiving plate 17 is rotated by the cooperation of motor 2 and circular rack 20. Then, the receiving plate 17 drives the stirring plate 18 to stir and mix the materials, thereby promoting the mixing of calcined coke powders of different particle sizes. An ion fan injects ion air into the premixing tank 2 to neutralize the positive and negative charges in the premixing tank 2, thereby effectively avoiding electrostatic adsorption.

[0022] Furthermore, multiple sets of baffles 14 symmetrical about the axis of the drive shaft 19 are fixedly connected to the upper end of the receiving plate 17. A rotating shaft 12 is rotatably connected between each pair of baffles 14 in each set. A gear 13 is fixedly sleeved on each rotating shaft 12. A receiving frame 21 is fixedly connected to the receiving plate 17. A motor 10 is fixedly connected to the upper end of the receiving frame 21, penetrating the top cover 3. The upper outer wall of the receiving frame 21 is rotatably connected to the top cover 3. The drive end of the motor 10 is fixedly connected to the drive shaft 19. A gear 11 is fixedly sleeved on the outer wall of the drive shaft 19, and the gear 11 meshes with the gear 2 13. A conveying assembly 7 is provided inside the premixing tank 2, and the conveying assembly 7 is connected to the drive shaft 19. An intercepting mesh plate 16 is slidably connected inside the premixing tank 2, and the intercepting mesh plate 16 is slidably connected to the stirring plate 18. A reciprocating assembly 15 is provided between the intercepting mesh plate 16 and the rotating shaft 12. A receiving ring 8 is fixedly connected to the outer wall of the conveying assembly 7, and a dispersing assembly 9 is provided on the receiving ring 8.

[0023] Understandably, a pump body is also installed on the conveying pipe between the cover 61 and the ion blower to ensure that the ion wind generated by the ion blower can enter the premix tank 2.

[0024] Specifically, the drive end of motor 10 drives the drive shaft 19 to rotate, and then the drive shaft 19 drives the conveying assembly 7 to move. The drive shaft 19 drives the rotating shaft 12 to rotate synchronously through the cooperation of gear 11 and gear 2 13. The material at the bottom of the premix tank 2 is conveyed to the intercepting screen plate 16 through the conveying assembly 7. Then, the intercepting screen plate 16 intercepts the agglomerated or accumulated material. The rotating shaft 12 drives the intercepting screen plate 16 to move up and down repeatedly through the reciprocating assembly 15, thereby causing the material on the intercepting screen plate 16 to oscillate, ensuring that the material that meets the requirements passes through the intercepting screen plate 16 to reach the lower position. During the lifting and lowering process, the intercepting screen plate 16 can also scrape off some of the material on the inner wall of the premix tank 2. The dispersing component 9 further disperses the agglomerated or accumulated material on the intercepting screen plate 16. The reciprocating component 15 gradually changes the force between the drive shaft 19 and the material on the intercepting screen plate 16 by raising and lowering. While the intercepting screen plate 16 rotates, it can effectively reduce the crushing of the material on the intercepting screen plate 16 by the dispersing component 9 (e.g., crushing coarse powder into fine powder). Moreover, it drives the dispersed material to vibrate, which helps the dispersed material pass through the intercepting screen plate 16 to reach the lower position. The conveying component 7 conveys the material at the bottom of the premixing tank 2 to the top of the intercepting screen plate 16, thereby forming a cycle.

[0025] like Figure 3 and Figure 4As shown, the conveying assembly 7 includes a support plate 71, a conveying cylinder 72, a spiral blade 73, a connecting rod 74, a fixing plate 75, and a discharge port 76. Multiple support plates 71 are fixedly connected to the bottom of the premix tank 2, and a conveying cylinder 72 is fixedly connected between the multiple support plates 71. The upper end of the conveying cylinder 72 abuts against a receiving plate 17. A fixing plate 75 is fixedly connected to the inner wall of the conveying cylinder 72, and a connecting rod 74 is rotatably connected to the inner wall of the fixing plate 75. The upper end of the connecting rod 74 is fixedly connected to the drive shaft 19, and a spiral blade 73 is wound around the outer wall of the connecting rod 74. The outer wall of the conveying cylinder 72 is fixedly connected to a receiving ring 8. Multiple discharge ports 76 are also provided on the outer wall of the conveying cylinder 72, and the discharge ports 76 are located between the receiving ring 8 and the fixing plate 75.

[0026] Specifically, the drive end of motor 10 drives the drive shaft 19 to rotate, the drive shaft 19 drives the connecting rod 74 to rotate, and then the connecting rod 74 drives the spiral blade 73 to rotate, so that the material at the bottom of the premix tank 2 is conveyed upward through the spiral blade 73, and then conveyed to the top of the intercepting screen plate 16 through the discharge port 76, and then intercepted and screened by the intercepting screen plate 16 to remove agglomerates and adsorbed accumulations.

[0027] like Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the reciprocating assembly 15 includes a second receiving groove 151, a sliding groove 152, a fixed roller 153, a curved groove 154, a second guide rod 155, a second slider 156, a rotating plate 157, and a protrusion 158; symmetrical receiving grooves 151 are provided on the first receiving plate 17, and a sliding groove 152 is provided at the bottom of each receiving groove 151; a fixed roller 153 is fixedly sleeved on the outer wall of the rotating shaft 12, and a curved groove 154 is provided on the fixed roller 153; the lower end of the first receiving plate 17... A second baffle (not marked in the figure) corresponding to the first baffle 14 is fixedly connected. A second guide rod 155 is fixedly connected between the two second baffles. A second slider 156 is slidably connected to the outer wall of the second guide rod 155. The upper end of the outer wall of the second slider 156 is slidably connected to the groove 152. A protrusion 158 is fixedly connected to the upper end of the second slider 156. The protrusion 158 abuts against the inner wall of the curved groove 154. A rotating plate 157 is provided between the second slider 156 and the intercepting mesh plate 16.

[0028] Furthermore, the outer wall of the fixed roller 153 abuts against the inner wall of the receiving groove 151, that is, the radius of the receiving groove 151 is the same as the radius of the fixed roller 153, thereby isolating the space inside the premix tank 2 from the top cover 3, effectively preventing dust inside the premix tank 2 from entering the top cover 3 through the receiving groove 151, thus facilitating cleaning.

[0029] Specifically, when motor 10 starts, the drive end of motor 10 drives the drive shaft 19 to rotate, then the drive shaft 19 drives gear 11 to rotate, then gear 11 drives gear 2 to rotate, then gear 2 13 drives the fixed roller 153 to rotate through the rotating shaft 12, then the fixed roller 153 drives the protrusion 158 to move through the curved groove 154, then the protrusion 158 drives the slider 2 156 to slide along the guide rod 2 155, the slider 2 156 drives the intercepting screen plate 16 to reciprocate up and down through the rotating plate 157, thereby driving the intercepting screen plate 16 to oscillate, thereby intercepting the agglomerated or adsorbed material on the intercepting screen plate 16, and screening the material that meets the requirements to fall below. In addition, the reciprocating component 15 changes the force between the drive shaft 19 and the material on the intercepting screen plate 16 by adjusting the lifting and lowering of the intercepting screen plate 16. While the intercepting screen plate 16 is rotating, it can effectively reduce the crushing of the intercepting screen plate 16 by the dispersing component 9, effectively ensuring the accuracy of the material ratio. In addition, during the startup process of the aforementioned motor 10, when the spiral blade 73 bears a large load resistance, the resistance will be transmitted to the motor 10 in sequence through the connecting rod 74 and the drive shaft 19. The motor 10 then transmits the resistance to the receiving plate 17 through the receiving frame 21. Since the gear at the end of the motor 2 drive shaft and the circular rack 20 always maintain a meshing engagement, this meshing engagement structure can effectively constrain the rotation trajectory of the receiving plate 17, ensuring that the receiving plate 17 is in a fixed state. This can effectively avoid the device vibration problem caused by the spiral blade 73 bearing a large load resistance. When motor 2 starts, the drive shaft of motor 2 moves relative to the circular rack 20 through the gear at the end. Since the top cover 3 is stationary, motor 2 and the receiving plate 17 rotate along the inner wall of the top cover 3. The receiving plate 17 drives the stirring plate 18 to rotate and stir the material. The receiving plate 17 simultaneously drives the intercepting mesh plate 16 to rotate along the inner wall of the premix tank 2 through the reciprocating component 15. That is, the intercepting mesh plate 16 rotates along the outer wall of the conveying cylinder 72, so that the dispersing component 9 can cover the material on the intercepting mesh plate 16 and disperse the clumps and adsorbed accumulations on the intercepting mesh plate 16 by rolling and squeezing, thereby ensuring that all clumps and adsorbed accumulations are dispersed.

[0030] In this invention, motor 10 and motor 2 can be started synchronously, thereby driving the intercepting screen plate 16 to rotate along the outer wall of the conveying cylinder 72 during a slow reciprocating lifting process, and the conveying component 7 conveys the material at the bottom to the intercepting screen plate in real time; alternatively, the drive shaft of motor 10 can be intermittently controlled to rotate during the slow rotation of the drive end of motor 2, so that the intercepting screen plate 16 intermittently rises or falls during the rotation along the outer wall of the conveying cylinder 72, thereby adjusting the contact time between the separating roller 94 and the intercepting screen plate 16, and the conveying component 7 intermittently conveys the material at the bottom to the intercepting screen plate, so that the material on the intercepting screen plate 16 is fully dispersed, thereby allowing for flexible adjustment of the single dispersion amount and dispersion intensity according to the degree of material agglomeration, improving the flexibility and adaptability of batching.

[0031] like Figure 3 , Figure 4 and Figure 6 As shown, the dispersing component 9 includes a receiving groove 91, a slider 92, a fixing rod 93, a separating roller 94, a spring 95, and a guide rod 96. Multiple receiving grooves 91 are provided on the outer wall of the receiving ring 8. A slider 92 is slidably connected to the inner wall of each receiving groove 91. A guide rod 96 is also fixedly connected to the inner wall of each receiving groove 91, and the guide rod 96 is slidably connected to the slider 92. A spring 95 is also provided between the slider 92 and the top of the receiving groove 91. A fixing rod 93 is fixedly connected to the outer wall of the slider 92. A separating roller 94 is rotatably sleeved on the outer wall of the fixing rod 93. Multiple protrusions (not shown in the figure) are provided on the separating roller 94.

[0032] Specifically, when motor 10 starts, reciprocating assembly 15 drives intercepting screen plate 16 to move up and down repeatedly. As reciprocating assembly 15 drives intercepting screen plate 16 to rise, intercepting screen plate 16 gradually approaches separating roller 94. As intercepting screen plate 16 continues to rise, intercepting screen plate 16 drives separating roller 94 to rise. Separating roller 94 drives slider 92 to slide up along the inner wall of receiving groove 91 through fixed rod 93. Slider 92 continuously compresses spring 95, thereby gradually increasing the deformation of spring 95. Spring 95 applies a gradually increasing force to slider 92. Slider 92 applies a gradually increasing force to intercepting screen plate 16 through fixed rod 93 and separating roller 94, thereby gradually dispersing the material on intercepting screen plate 16, avoiding excessive force that would cause most of the material to be crushed, and thus avoiding particle size imbalance caused by over-crushing. During the startup process of the aforementioned motor 10, when the spiral blade 73 bears a large load resistance, this resistance will be transmitted to the motor 10 in sequence through the connecting rod 74 and the drive shaft 19. The motor 10 then transmits the resistance to the receiving plate 17 through the receiving frame 21. Since the gear at the end of the motor 2 drive shaft and the circular rack 20 always maintain a meshing engagement, this meshing engagement structure can effectively constrain the rotation trajectory of the receiving plate 17, ensuring that the receiving plate 17 is in a fixed state. This can effectively avoid the device vibration problem caused by the spiral blade 73 bearing a large load resistance.

[0033] When motor 2 starts, the drive shaft of motor 2 moves relative to the circular rack 20 through the gear at the end. Since the top cover 3 is stationary, motor 2 and receiving plate 17 rotate along the inner wall of the top cover 3. The receiving plate 17 drives the intercepting mesh plate 16 to rotate along the inner wall of the premix tank 2 through the reciprocating assembly 15, that is, the intercepting mesh plate 16 rotates along the outer wall of the conveying cylinder 72, so that the separating roller 94 can cover the material on the intercepting mesh plate 16.

[0034] The working principle of this invention is as follows: Calcined coke powders of different particle sizes are sequentially added to the premixing tank 2 through the feed hopper. The weighing module on the premixing tank 2 identifies the amount of each type of calcined coke powder added, controlling the start of motor 10 and motor 2. Motor 10 drives the drive shaft 19 to rotate, which in turn drives the conveying assembly 7. The drive shaft 19 synchronously drives the rotating shaft 12 to rotate via gear 2 13. The rotating shaft 12 then drives the fixed roller 153 to rotate. Subsequently, the fixed roller 153 moves the protrusion 158 via the curved groove 154. The protrusion 158 then drives the slider 2 156 to slide along the guide rod 2 155. The slider 2 156 drives the intercepting mesh plate 16 to reciprocate up and down via the rotating plate 157, thereby causing the intercepting mesh plate 16 to oscillate, thus intercepting... Materials that are agglomerated or adsorbed on the screen plate 16 are screened and fall below if they meet the requirements. The reciprocating component 15 gradually changes the force between the drive shaft 19 and the material on the screen plate 16 by adjusting the distance between the screen plate 16 and the dispersing component 9. While the screen plate 16 is rotating, it can effectively reduce the crushing of the screen plate 16 by the dispersing component 9, effectively ensuring the accurate material ratio. The reciprocating component 15 gradually changes the force between the drive shaft 19 and the material on the screen plate 16 by adjusting the height of the screen plate 16. While the screen plate 16 is rotating, it can effectively reduce the crushing of the screen plate 16 by the dispersing component 9, effectively ensuring the accurate material ratio. Moreover, it drives the dispersed material to vibrate, which helps the dispersed material pass through the screen plate 16 and reach the lower position. The second motor drives the shaft to move relative to the circular rack 20 through the gear at the end. Since the top cover 3 is stationary, the second motor and the first receiving plate 17 rotate along the inner wall of the top cover 3. The first receiving plate 17 drives the stirring plate 18 to rotate and stir the material. The first receiving plate 17 simultaneously drives the intercepting mesh plate 16 to rotate along the inner wall of the premix tank 2 through the reciprocating assembly 15. That is, the intercepting mesh plate 16 rotates along the outer wall of the conveying cylinder 72, so that the dispersing assembly 9 can cover the material on the intercepting mesh plate 16 and disperse the clumps and adsorbed accumulations on the intercepting mesh plate 16 by rolling and squeezing, thereby ensuring that all clumps and adsorbed accumulations are dispersed. During this process, the combination of negative pressure device and dust removal device effectively reduces dust leakage during the batching process and effectively reduces dust concentration in the mixing chamber. By adding a small amount of dust collected by the dust collector to the next process, and injecting ion wind into the premixing tank 2 through the ion fan, the positive and negative charges in the premixing tank 2 are neutralized, thereby effectively reducing electrostatic adsorption.
