Description

Technical Field

[0001] This utility model relates to the field of petroleum coke calcination feeding technology, specifically a petroleum coke calcination feeder. Background Technology

[0002] In the petroleum coke calcination process, the feeding stage is crucial, and its performance directly affects the calcination effect and production efficiency. Currently, most petroleum coke calcination feeders on the market have revealed a series of problems that urgently need to be solved when dealing with the characteristics of petroleum coke, especially in the handling of materials that cannot be crushed.

[0003] During the mining, transportation, and storage of petroleum coke, various factors often result in it taking on a large, blocky form, sometimes even containing hard impurities. For example, common blocky petroleum coke can sometimes reach tens of centimeters in size. Traditional feeders, due to limitations in their structure and operating principle, lack an effective crushing mechanism when conveying this material. When blocky petroleum coke enters the feeder directly, it can cause blockages in the feeding channel, preventing the material from being smoothly transported to the calcining furnace and thus affecting the continuity of the entire production process.

[0004] According to the patent application published on the Internet, a feeding device for quartz calcination (authorization announcement number: CN218627772U) is described as including "shell, channel, and feed inlet" to realize the feeding work.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This quartz calcination feeding device utilizes a shell, channel, and feed inlet to achieve feeding. However, this device can only feed through an auger during operation. It cannot crush the quartz during feeding and cannot control the amount of material being fed, thus affecting the efficiency and quality of calcination. Therefore, this device needs to be improved.

[0014] Preferably, the second feeding mechanism includes a feeding frame, which is fixedly connected to the top of the feeding device body. A third servo motor is fixedly connected to the left side of the feeding frame, and a rotating shaft is fixedly connected to the right side of the third servo motor. The rotating shaft is rotatably connected to the inside of the feeding frame on the right side. An auger is fixedly connected to the periphery of the rotating shaft. A mounting bracket is fixedly connected to the top of the feeding frame, and a heating tube is fixedly connected to the inner side of the mounting bracket. A connecting bracket is fixedly connected to the top of the feeding frame, and a discharge pipe is fixedly connected to the bottom right side of the feeding frame.

[0015] Preferably, the top of the feeding frame is fixedly connected to the bottom of the conveying pipe, and the connecting frame is fixedly connected to the right side of the storage box, so as to further ensure the stability of the feeding frame under the action of the connecting frame.

[0017] Compared with the prior art, this utility model provides a petroleum coke calcination feeder, which has the following beneficial effects:

[0018] 1. This petroleum coke calcination feeder, through its first feeding mechanism, first feeds petroleum coke into a storage bin. The threaded rod and moving frame then move the sealing cover, sealing the top of the storage bin to prevent environmental pollution from crushing and to avoid petroleum coke splashing. The crushing teeth and crushing rollers mesh with each other, and driven by a first servo motor, effectively crushing the petroleum coke, refining large pieces of material for subsequent feeding and calcination, greatly improving the calcination efficiency. The first cylinder drives... The moving tamping rod slides inside the sealed cover to compact the material in the storage box, preventing the material from slipping during the crushing process and failing to enter the crushing roller for crushing. The baffle inside the conveying pipe can slide under the action of the second cylinder, thereby precisely controlling the flow rate of material from the storage box into the second feeding mechanism. This avoids excessive material from adversely affecting the calcination process and ensures the stability and controllability of the feeding process. The storage box is rectangular with an inclined bottom and four sides, which facilitates the material to slide down the conveying pipe by its own gravity, reducing material residue.

[0019] 2. This petroleum coke calcination feeder, through a second feeding mechanism, positions the discharge pipe at the top of the calcination furnace. When the petroleum coke is pulverized and conveyed to the feeding frame through the conveying pipe, the rotating shaft and auger are driven by the third servo motor, which can smoothly convey the material to the discharge pipe, achieving continuous feeding. The heating pipes symmetrically distributed on the upper and lower sides of the feeding frame, fixed by the mounting frame, can heat the material in the feeding frame, preheating it and accelerating the calcination reaction, thereby improving calcination efficiency and reducing damage to the calcination equipment caused by uneven material temperature.

A sealing cover 34 is fixedly connected to the right side of the movable frame 392. A concave frame 393 is fixedly connected to the top of the sealing cover 34. A first cylinder 394 is fixedly connected to the top of the concave frame 393. A tamping rod 395 is fixedly connected to the bottom of the first cylinder 394. A fixed frame 396 is fixedly connected to the bottom left side of the storage box 31. A conveying pipe 32 is fixedly connected to the bottom of the storage box 31.

[0036] The crushing teeth 39 and the crushing roller 38 mesh with each other. The rear side of the rotating rod 37 is rotatably connected to the storage box 31.

[0037] The storage box 31 is rectangular, and the bottom of the storage box 31 is inclined around the perimeter to facilitate the smooth discharge of petroleum coke. The sealing cover 34 has a groove inside, and the tamping rod 395 is slidably connected in the groove to facilitate the movement of the tamping rod 395 inside the sealing cover 34.

[0038] Example 2

[0039] Please see Figure 1-8Furthermore, based on Embodiment 1, the second feeding mechanism 4 includes a feeding frame 41, which is fixedly connected to the top of the feeding device body 1. A third servo motor 42 is fixedly connected to the left side of the feeding frame 41, and a rotating shaft 47 is fixedly connected to the right side of the third servo motor 42. The right side of the rotating shaft 47 is rotatably connected inside the feeding frame 41, and an auger 48 is fixedly connected to the periphery of the rotating shaft 47. A mounting bracket 43 is fixedly connected to the top of the feeding frame 41, and a heating tube 44 is fixedly connected to the inner side of the mounting bracket 43. A connecting bracket 45 is fixedly connected to the top of the feeding frame 41, and a discharge pipe 46 is fixedly connected to the bottom right side of the feeding frame 41.

[0040] The top of the feeding frame 41 is fixedly connected to the bottom of the conveying pipe 32, and the connecting frame 45 is fixedly connected to the right side of the storage box 31. This facilitates the stability of the feeding frame 41 under the action of the connecting frame 45. There are two sets of mounting frames 43 and heating pipes 44. The two sets of mounting frames 43 and heating pipes 44 are symmetrically distributed on the upper and lower sides of the feeding frame 41, and the outer periphery of the two sets of heating pipes 44 is in contact with the outer periphery of the feeding frame 41, so that the petroleum coke can be preheated through the heating pipes 44.

[0041] In actual operation, when this device is used, the feeding pipe 46 is placed at the feed inlet at the top of the calcining furnace, and the petroleum coke is put into the storage box 31. The second servo motor 36 drives the moving frame 392 connected to the threaded rod 391 to move, which in turn drives the sealing cover 34 to move. Thus, the top of the storage box 31 can be sealed under the action of the sealing cover 34 to avoid the pollution of the environment caused by crushing, and at the same time, to prevent the petroleum coke from splashing.

[0042] At the same time, the first servo motor 33 drives the crushing roller 38 fixedly connected to the outer periphery of the rotating rod 37 to rotate. The crushing teeth 39 mesh with the crushing roller 38, which can effectively crush the petroleum coke, refine the large pieces of material, facilitate subsequent feeding and calcination, and greatly improve the calcination efficiency of the material. The crushed petroleum coke will fall into the bottom of the storage box 31. The storage box 31 is rectangular and the bottom of the inner side is inclined, which is conducive to the material sliding down the conveying pipe 32 by its own gravity, reducing material residue.

[0043] During the crushing process, the first cylinder 394 drives the tamping rod 395 to slide inside the sealing cover 34, which can tamp the material in the storage box 31 and prevent the material from sliding during the crushing process and failing to enter the crushing roller 38 for crushing. The baffle 398 in the conveying pipe 32 can slide under the action of the second cylinder 397, thereby accurately controlling the flow rate of material from the storage box 31 into the second feeding mechanism 4, avoiding excessive material from adversely affecting the calcination process, and ensuring the stability and controllability of the feeding process.

[0044] When petroleum coke enters the feeding frame 41, the third servo motor 42 drives the rotating shaft 47 and the auger 48 to work, which can smoothly transport the material to the discharge pipe 46 to achieve continuous feeding. The heating pipes 44, which are symmetrically distributed on the upper and lower sides of the feeding frame 41, can heat the material in the feeding frame 41 under the fixation of the mounting bracket 43, which can play a preheating role, accelerate the calcination reaction, thereby improving the calcination efficiency and reducing the damage to the calcination equipment caused by uneven material temperature.

[0045] During the opening and closing process of the sealing cover 34, the first cylinder 394 needs to drive the tamping rod 395 to move to the top of the sealing cover 34 to avoid affecting the movement of the sealing cover 34. The distance that the tamping rod 395 moves can only be to the top of the crushing roller 38.

[0046] In use, the first servo motor 33, the second servo motor 36, the third servo motor 42, the first cylinder 394, the second cylinder 397, and the auger 48 can be connected to the same PLC control system to ensure coordinated operation between the devices. Furthermore, the PLC control system is existing technology, and those skilled in the art are well aware of the specific usage methods and steps of the system.
