Description

Technical Field

[0001] This utility model belongs to the field of coke tower technology, and specifically relates to a coke tower decoking device used in the needle coke production process. Background Technology

[0002] Coking is a refining process primarily used for processing residual oil, especially low-quality vacuum residue. Coking uses heavy oil, residual oil, and even bitumen as raw materials, which are heated and then fed into a coking tower. Under specific temperature and pressure conditions, cracking and condensation reactions occur, producing products such as gas, gasoline, wax oil, and coke. During coking, coke slowly deposits inside the coking tower, becoming tightly embedded in the tower walls and very difficult to remove. If this coke is not removed promptly, it will severely affect the operation of the coking tower and even the quality of the coked products. Therefore, decoking is a crucial step in the coking process.

[0003] In the prior art, such as Chinese Patent Publication No. CN209113814U, a coking tower decoking device is provided. This patent includes a tower body, a decoking disc is provided inside the tower body, several grooves are opened around the decoking disc, a slider is provided in the groove and slidably connected thereto, a spring is provided between the slider and the groove, a blade holder is provided on the end face of the slider away from the spring, a detachable decoking blade is provided in the blade holder, a crossbeam is provided above the tower body, several cylinders are provided between the crossbeam and the tower body, an inverted motor is provided on the crossbeam, and a rotating shaft is provided below the motor.

[0004] However, in the aforementioned patent, since only a single set of blades is used to clean the inside of the tower, although the cleaning purpose can be achieved, there are many places that are missed when cleaning with a single set of blades, which often requires secondary cleaning. In addition, since the decoking blade and the decoking disc are connected by a single spring, the structure is relatively simple, the stability is poor, and there are inconveniences and certain limitations in use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coke tower decoking device for needle coke production processes.

[0006] To achieve the above objectives, this utility model provides a coke tower decoking device for needle coke production process, including a base, a fixed seat fixedly connected to the middle of the upper part of the base, a cylinder fixedly connected to the lower part of the base, an installation block fixedly connected to the output end of the cylinder, an installation bolt connected to the internal thread of the installation block, a rotating mechanism provided below the base, and a decoking mechanism provided below the base.

[0007] The rotating mechanism is used to provide power to the decoking mechanism;

[0008] The coke removal mechanism is used to clean the interior of the coke tower.

[0009] In the above technical solution, the rotating mechanism further includes a sleeve rod, a limiting block is fixedly connected to the outside of the sleeve rod, the limiting block is rotatably connected to the base, and a rotating shaft is rotatably connected inside the sleeve rod.

[0010] In the above technical solution, bevel gears are fixedly connected to both the end of the rotating shaft and the end of the sleeve rod, and a motor is fixedly connected above the fixed base. The output end of the motor is fixedly connected to the bevel gear at the end of the rotating shaft.

[0011] In the above technical solution, the two bevel gears are rotatably connected inside the fixed base.

[0012] In the above technical solution, the desiccant removal mechanism further includes a desiccant removal disc, and the two desiccant removal discs are respectively fixedly connected to the ends of the sleeve rod and the rotating shaft.

[0013] In the above technical solution, a fixed rod is fixedly connected inside the decoking disc, a sliding block is slidably connected to the outer wall of the fixed rod, a first spring is fixedly connected to one side of the sliding block, and the first spring is sleeved on the outside of the fixed rod.

[0014] In the above technical solution, a support rod is rotatably connected to one side of the sliding block, and a blade is rotatably connected to the end of the support rod. The blade is slidably connected to the decoking disc, and a second spring is fixedly connected inside the decoking disc. The end of the second spring is fixedly connected to one side of the blade.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, when the motor starts, it will drive the two decoking discs to rotate simultaneously in opposite directions, so that the two sets of blades can clean the coke on the inner wall of the tower at the same time, avoiding the omission problem caused by cleaning with a single set of blades, thereby improving the cleaning efficiency.

[0017] 2. In this utility model, when the blade touches the inner wall of the tower, the sliding block will slide on the outer wall of the fixed rod and move closer to each other. During this process, both the first spring and the second spring will undergo elastic deformation, causing the blade to slide towards the inside of the decoking disc, thus avoiding damage to the inner wall of the tower. Compared with the connection between the blade and the decoking disc using a single spring, the connection between the blade and the decoking disc using a support rod improves the structural strength of the blade inside the decoking disc, thereby enhancing the overall structural stability.

[0026] like Figure 1 - Figure 3The coke tower decoking device shown includes a base 1, a fixed seat 11 fixedly connected to the middle of the upper part of the base 1, a cylinder 12 fixedly connected to the lower part of the base 1, a mounting block 13 fixedly connected to the output end of the cylinder 12, a mounting bolt 14 threadedly connected to the mounting block 13, a rotating mechanism 2 and a decoking mechanism 3 arranged below the base 1; the rotating mechanism 2 provides power to the decoking mechanism 3; the decoking mechanism 3 is used to clean the inside of the coke tower. The rotating mechanism 2 includes a sleeve 21, a limiting block 23 fixedly connected to the outside of the sleeve 21, the limiting block 23 and the base 1 being rotatably connected, a rotating shaft 22 rotatably connected inside the sleeve 21, bevel gears 24 fixedly connected to the end of the rotating shaft 22 and the end of the sleeve 21, a motor 25 fixedly connected to the upper part of the fixed seat 11, the output end of the motor 25 and the bevel gears 24 at the end of the rotating shaft 22 being fixedly connected, and the two bevel gears 24 being rotatably connected inside the fixed seat 11.

[0027] In this embodiment, when the motor 25 starts, it will directly drive the rotating shaft 22 to rotate. During the rotation of the rotating shaft 22, the sleeve rod 21 will rotate in the opposite direction to the rotating shaft 22 through the transmission of the bevel gear 24. The two bevel gears 24 inside the fixed seat 11 play a transmission role and can increase the stability of the transmission between the sleeve rod 21 and the rotating shaft 22.

[0028] Example 2

[0029] like Figure 1 - Figure 3 The diagram shows a coke tower decoking device for needle coke production. The decoking mechanism 3 includes a decoking disc 31. Two decoking discs 31 are fixedly connected to the ends of a sleeve rod 21 and a rotating shaft 22, respectively. A fixed rod 32 is fixedly connected inside the decoking disc 31. A sliding block 33 is slidably connected to the outer wall of the fixed rod 32. A first spring 35 is fixedly connected to one side of the sliding block 33. The first spring 35 is sleeved on the outside of the fixed rod 32. A support rod 34 is rotatably connected to one side of the sliding block 33. A blade 36 is rotatably connected to the end of the support rod 34. The blade 36 is slidably connected to the decoking disc 31. A second spring 37 is fixedly connected inside the decoking disc 31. The end of the second spring 37 is fixedly connected to one side of the blade 36.

[0030] In this embodiment, when the rotating shaft 22 and the sleeve rod 21 rotate in opposite directions, the two decoking discs 31 rotate simultaneously in opposite directions. During the rotation of the decoking discs 31, the blades 36 clean the inner wall of the coke tower. When the blades 36 touch the inner wall of the tower, the sliding blocks 33 slide on the outer wall of the fixed rod 32 and move closer to each other. During this process, the first spring 35 and the second spring 37 will undergo elastic deformation, causing the blades 36 to slide towards the inside of the decoking discs 31, thus avoiding damage to the inner wall of the tower by the blades 36.

[0031] Working principle: During coke removal, the top of the coke tower can be removed first. Then, the two cylinders 12 are fixed above the tower body by the mounting block 13 and mounting bolts 14. Then, the motor 25 is started to make the two coke removal discs 31 rotate in opposite directions. At the same time, the cylinders 12 can be started to drive the base 1 to move upward, thereby achieving all-round removal of coke from the inner wall of the tower.
