Description

Technical Field

[0001] This utility model relates to the field of blending equipment technology, and in particular to a blending equipment for calcined petroleum coke. Background Technology

[0002] In today's industrial sector, calcined petroleum coke plays a crucial role as a key raw material in numerous production processes. The quality and performance of calcined petroleum coke directly affect the quality of the final product, and the uniformity and precision of its blending are even more critical factors.

[0003] In actual production, calcined petroleum coke blending units typically need to meet the following key technical requirements:

[0004] 1. A high-precision metering system to ensure accurate proportions of various ingredients.

[0005] 2. The efficient mixing mechanism enables rapid and uniform mixing.

[0006] 3. Good sealing performance to prevent material leakage and the mixing of external impurities.

[0007] 4. Automated control program, which facilitates operation and monitoring of the mixing process.

[0008] Currently, there are various types of calcined petroleum coke blending equipment on the market.

[0009] For example, a Chinese patent discloses a petroleum coke batching device for a calcining furnace, patent number: CN221693540U. The device uses a dual-shaft output reducer to simultaneously drive the spiral push rods on both sides to rotate, which can improve the working efficiency and stability of the conveying components, thereby improving the conveying efficiency of raw materials.

[0010] However, the above method has a prominent problem: the device feeds materials by rotating a screw pusher, but it lacks an adjustment mechanism for the feeding channel, which makes it inflexible and unadjustable. This makes it difficult to accurately control the amount of material fed, which may result in too much or too little material being fed, affecting the accuracy and efficiency of mixing. Utility Model Content

[0011] (a) Technical problems to be solved

[0012] To address the shortcomings of existing technologies, this utility model provides a calcined petroleum coke blending device, which solves the technical problem that the above-mentioned devices use a rotating screw pusher for feeding, lack an adjustment mechanism for the feeding channel, lack flexibility and adjustability, and make it difficult to achieve precise control of the feeding amount, which may lead to excessive or insufficient feeding, affecting the accuracy and efficiency of blending.

[0013] (II) Technical Solution

[0014] To achieve the above objectives, this utility model provides the following technical solution:

[0015] A calcined petroleum coke blending device includes a mixing tank. A baffle is fixedly connected inside the mixing tank. A connecting rod is rotatably connected inside the baffle. Two sliders are sleeved inside the connecting rod. Both sliders are slidably connected inside the baffle. A set of quadrilateral blocks is fixedly connected inside each of the two sliders. Each set of quadrilateral blocks has a feeding hole. An eccentric rod is rotatably connected inside the baffle and sleeved inside the connecting rod. A feeding mechanism is rotatably connected inside the mixing tank. The feeding mechanism includes two spiral conveying rods, both of which are rotatably connected inside the mixing tank.

[0016] Preferably, a synchronous belt is fitted onto the outer surface of both spiral conveyor rods, and a first motor is fixedly connected to the upper end of the mixing tank.

[0017] Preferably, the upper end of the mixing tank is fixedly connected to two feeding hoppers, and each of the two feeding hoppers is fitted with a filter plate.

[0018] Preferably, a discharge pipe is fixedly connected inside the mixing tank, and a second motor is fixedly connected to the lower end of the mixing tank.

[0019] Preferably, a first stirring rod is sleeved on the outer surface of the second motor, and a sleeve is fixedly connected to the outer surface of the first stirring rod.

[0020] Preferably, the sleeve contains two second stirring rods that are rotatably connected inside, and the outer surfaces of the two second stirring rods and the first stirring rod are all fitted with bevel gears.

[0021] (III) Beneficial Effects

[0022] 1. During the feeding process, the eccentric rod can be turned to rotate the connecting rod. During the rotation of the connecting rod, the two sliders are pulled to slide in opposite directions. The two sliders pull two quadrilateral blocks from the two sets of quadrilateral blocks to slide. When the two quadrilateral blocks slide in opposite directions, they will squeeze the other four quadrilateral blocks along the inner wall of the baffle to change the size of the feeding hole. This allows for precise adjustment of the petroleum coke feed rate according to production needs and process requirements, ensuring the accuracy of the mixing ratio. It can adapt to the feeding needs of different types and specifications of petroleum coke, increasing the applicability and versatility of the equipment.

[0023] 2. When stirring is required after the petroleum coke is fed, the output shaft of the second motor drives the first stirring rod to rotate. The rotation of the first stirring rod stirs and mixes the petroleum coke. During the rotation, the first stirring rod drives the sleeve to rotate. As the sleeve is rotated, the bevel gears outside the first stirring rod mesh with the two bevel gears outside the second stirring rod to rotate. At this time, the second stirring rod rotates on its own axis while being driven to rotate by the first stirring rod, which increases the diversity of the stirring force on the petroleum coke, making the mixing more uniform and improving the quality of the processed petroleum coke.

[0030] This application provides a calcined petroleum coke blending device, which effectively solves the problems of the above-mentioned devices that use a rotating screw pusher for feeding, lack an adjustment mechanism for the feeding channel, lack flexibility and adjustability, and are difficult to accurately control the feeding amount, which may lead to too much or too little feeding, affecting the accuracy and efficiency of blending. During the feeding operation, the eccentric rod can be turned, which drives the connecting rod to rotate. During the rotation of the connecting rod, the two sliders are pulled to slide in opposite directions. The two sliders pull two quadrilateral blocks in two sets of quadrilateral blocks to slide. When the two quadrilateral blocks slide in opposite directions, they will squeeze the other four quadrilateral blocks to slide along the inner wall of the baffle, thereby changing the size of the feeding hole opening. It can accurately adjust the feeding amount of petroleum coke according to production needs and process requirements, ensuring the accuracy of the blending ratio. It can adapt to the feeding needs of different types and specifications of petroleum coke, increasing the applicability and versatility of the equipment. Example

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that the above-mentioned device, which uses a rotating screw pusher for feeding, lacks an adjustment mechanism for the feeding channel, resulting in a lack of flexibility and adjustability, making it difficult to accurately control the feeding amount, which may lead to excessive or insufficient feeding, affecting the accuracy and efficiency of mixing. The overall idea is as follows: A calcined petroleum coke mixing device includes a mixing tank 11, a baffle 12 fixedly connected inside the mixing tank 11, a connecting rod 13 rotatably connected inside the baffle 12, two sliders 14 sleeved inside the connecting rod 13, both sliders 14 slidably connected inside the baffle 12, and a set of quadrilateral blocks 15 fixedly connected inside each of the two sliders 14. Each set of quadrilateral blocks 15 has a feeding hole 16 inside, and an eccentric rod 17 rotatably connected inside the baffle 12. The eccentric rod 17 is sleeved inside the connecting rod 13. During feeding, the eccentric rod 17 (the upper end of the eccentric rod 17 is eccentrically connected to a cylinder) can be screwed on. The cylinder is sleeved inside the connecting rod 13. The connecting rod 13 is rotated by the eccentric rod 17. During the rotation of the connecting rod 13, the two sliders 14 are pulled to slide in opposite directions. The two sliders 14 pull the two sets of quadrilateral blocks 15 (there are two sets of quadrilateral blocks 15 sliding inside the baffle 12. Each set of quadrilateral blocks 15 consists of six quadrilateral blocks. The quadrilateral blocks in each set are in close contact with each other. When two quadrilateral blocks in a set of quadrilateral blocks 15 slide in opposite directions, they will squeeze the other four quadrilateral blocks to slide along the inner wall of the baffle 12) to change the size of the feed hole 16. It can accurately adjust the feed amount of petroleum coke according to production needs and process requirements, ensure the accuracy of the mixing ratio, adapt to the feeding needs of different types and specifications of petroleum coke, and increase the applicability and versatility of the equipment.

[0032] A feeding mechanism is rotatably connected inside the mixing tank 11. The feeding mechanism includes two spiral conveyor rods 18, both rotatably connected inside the mixing tank 11. Both spiral conveyor rods 18 and two sets of quadrilateral baffles 15 are on the same vertical line. Synchronous belts 19 are fitted onto the outer surfaces of both spiral conveyor rods 18. A first motor 21 is fixedly connected to the upper end of the mixing tank 11, fitted inside the two spiral conveyor rods 18. Two feeding hoppers 22 are fixedly connected to the upper end of the mixing tank 11, each containing a filter plate 23. A discharge pipe 24 is fixedly connected inside the mixing tank 11. A second motor 25 is fixedly connected to the lower end of the mixing tank 11, with a first stirring rod 26 fitted onto its outer surface. Calcined petroleum coke is fed into the mixing tank 11 through the feeding hoppers 22 (the feeding hoppers 22 have an inclined discharge channel; after being fed into the feeding hoppers 22, the petroleum coke will flow along the inclined channel). The petroleum coke falls into the mixing tank 11. A filter plate 23 is fitted inside the feeding hopper 22. The filter plate 23 blocks and filters large pieces of petroleum coke. At this time, the first motor 21 is started. The output shaft of the first motor 21 drives a screw conveyor 18 to rotate. Both screw conveyors 18 are fitted with synchronous belts 19 on their outer surfaces. At this time, one screw conveyor 18 drives the other screw conveyor 18 to rotate through the synchronous belt 19. The rotation of the two screw conveyors 18 evenly conveys the petroleum coke in the feeding hopper 22 downwards for feeding. The petroleum coke conveyed downwards by the screw conveyors 18 passes through the two feeding holes 16 opened in the baffle 12 and falls into the mixing tank 11 to complete the feeding work. At this time, the second motor 25 under the mixing tank 11 is started. The output shaft of the second motor 25 drives the first stirring rod 26 to rotate. The rotation of the first stirring rod 26 mixes and stirs the petroleum coke. The evenly mixed petroleum coke is discharged through the discharge pipe 24 for use.

[0033] A sleeve 27 is fixedly connected to the outer surface of the first stirring rod 26. Two second stirring rods 28 are rotatably connected inside the sleeve 27. Bevel gears 29 are fitted onto the outer surfaces of both second stirring rods 28 and the first stirring rod 26. The three bevel gears 29 mesh with each other. When stirring is required after the petroleum coke is fed, the output shaft of the second motor 25 drives the first stirring rod 26 to rotate. The rotation of the first stirring rod 26 stirs and mixes the petroleum coke. During the rotation, the first stirring rod 26 drives the sleeve 27 to rotate. As the sleeve 27 is rotated, the bevel gears 29 on the outside of the first stirring rod 26 mesh with and drive the bevel gears 29 on the outside of the two second stirring rods 28 to rotate. At this time, the second stirring rods 28 rotate on their own axis while being driven to rotate by the first stirring rod 26, increasing the diversity of the stirring force on the petroleum coke, making the mixing more uniform, and improving the quality of the processed petroleum coke.

[0034] To address the problems existing in the prior art, this utility model provides a calcined petroleum coke blending device. During the feeding process, the eccentric rod 17 can be rotated, which drives the connecting rod 13 to rotate. During the rotation of the connecting rod 13, the two sliders 14 are pulled to slide in opposite directions. The two sliders 14 pull two quadrilateral blocks in the two sets of quadrilateral blocks 15 to slide. When the two quadrilateral blocks slide in opposite directions, they will squeeze the other four quadrilateral blocks to slide along the inner wall of the baffle 12, thereby changing the opening size of the feeding hole 16. It can accurately adjust the feed amount of petroleum coke according to production needs and process requirements, ensuring the accuracy of the blending ratio. It can adapt to the feeding needs of different types and specifications of petroleum coke, increasing the applicability and versatility of the equipment.

[0035] Working principle:

[0036] The first step involves feeding the calcined petroleum coke into the mixing tank 11 through the feeding hopper 22 (the feeding hopper 22 has an inclined feeding channel, so the petroleum coke will fall into the mixing tank 11 along the inclined channel after being fed into the feeding hopper 22). A filter plate 23 is fitted inside the feeding hopper 22 to filter out large pieces of petroleum coke. At this time, the first motor 21 is started, and the output shaft of the first motor 21 drives one screw conveyor rod 18 to rotate. (Both screw conveyor rods 18 are fitted with synchronous pulleys, which are fitted inside synchronous belts 19). Synchronous belts 19 are fitted onto the outer surfaces of both screw conveyor rods 18. At this time, one… The screw conveyor 18 drives another screw conveyor 18 to rotate via the synchronous belt 19. The rotation of the two screw conveyors 18 evenly conveys the petroleum coke in the hopper 22 downwards for feeding. The petroleum coke conveyed downwards by the screw conveyors 18 passes through the two feeding holes 16 in the baffle 12 and falls into the mixing tank 11 to complete the feeding. At this time, the second motor 25 under the mixing tank 11 starts. The output shaft of the second motor 25 drives the first stirring rod 26 to rotate. The rotation of the first stirring rod 26 mixes and stirs the petroleum coke. The evenly mixed petroleum coke is discharged through the discharge pipe 24 for use.

[0037] The second step involves rotating the eccentric rod 17 (the upper end of the eccentric rod 17 is eccentrically connected to a cylinder, which is fitted inside the connecting rod 13) during the feeding process. This rotation of the eccentric rod 17 drives the connecting rod 13 to rotate, pulling the two sliders 14 in opposite directions. The two sliders 14 then pull the two sets of quadrilateral blocks 15 (two sets of quadrilateral blocks 15 slide within the baffle 12; each set consists of six quadrilateral blocks, and these blocks are interlocked. When two quadrilateral blocks in one set slide in opposite directions, they compress the other four quadrilateral blocks, causing them to slide along the inner wall of the baffle 12). This changes the size of the feeding hole 16, allowing for adjustments based on the desired feeding method. According to production needs and process requirements, the feed rate of petroleum coke is precisely adjusted to ensure the accuracy of the mixing ratio. It can adapt to the feeding needs of different types and specifications of petroleum coke, increasing the applicability and versatility of the equipment. When stirring is required after the petroleum coke is fed, the output shaft of the second motor 25 drives the first stirring rod 26 to rotate. The rotation of the first stirring rod 26 stirs and mixes the petroleum coke. During the rotation, the first stirring rod 26 drives the sleeve 27 to rotate. As the sleeve 27 is rotated, the bevel gear 29 outside the first stirring rod 26 meshes with and drives the bevel gear 29 outside the two second stirring rods 28 to rotate. At this time, the second stirring rods 28 rotate on their own axis while being driven to rotate by the first stirring rod 26, increasing the diversity of the stirring force on the petroleum coke, making the mixing more uniform, and improving the quality of the processed petroleum coke.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
