Description

Technical Field

[0001] This patent relates to the field of coke tower decoking, specifically a vertical coke tower decoking device. Background Technology

[0002] A coke tower is a piece of equipment used for coke processing, while a coke removal device is used to remove coke from inside the coke tower.

[0003] The vertical coke tower decoking device proposed in application number CN202122365261.1 improves the usability of the device by setting up a decoking mechanism to collect and process the coke waste generated during the decoking process in a centralized manner.

[0004] However, the decoking devices proposed in the above documents still have the following drawbacks in actual use;

[0005] The coking mechanism in this coking removal device has a fixed position and cannot be properly adjusted according to the inner diameter of the coke tower, resulting in poor applicability.

[0006] The coke removal device mainly uses a telescopic rod to apply a pushing force to the ground, thereby raising the device inside the coke tower. However, due to the limited length of the telescopic rod, the coke tower is generally quite high, making it inconvenient to use. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a vertical coke tower decoking device.

[0008] The technical solution adopted by this patent to solve its technical problem is: a vertical coke tower decoking device, including a crossbar and a drive mechanism. A bidirectional electrically controlled push rod is installed in the inner cavity of the crossbar. The bidirectional electrically controlled push rod is electrically connected to an external power source. A drive mechanism is installed at the output ends on both sides of the bidirectional electrically controlled push rod. The drive mechanism can fit against the inner wall of the external coke tower.

[0009] The drive mechanism includes a fixed plate, a motor, a rotating sleeve, and a top holding plate. The fixed plate is installed at the output end of the bidirectional electric push rod. The motor is installed on the side wall of the fixed plate and is electrically connected to an external power source. The rotating sleeve is installed through the side wall of the fixed plate at the output end of the motor. The top holding plate is installed on the side wall of the rotating sleeve and can fit against the inner wall of the external coke tower.

[0010] A desiccation mechanism is installed on the outer side of the output end of the bidirectional electronically controlled push rod, and the desiccation mechanism is located above the drive mechanism.

[0011] Furthermore, the decoking mechanism includes a fixed rod, a through hole, a sliding rod, and a scraper. The side wall of the fixed rod has a connecting hole, and the fixed rod is installed on the outside of the output end of the bidirectional electrically controlled push rod through the connecting hole. The side wall of the fixed rod has a through hole, and a sliding rod is slidably installed in the through hole. A scraper is installed on the upper wall of the sliding rod, and the scraper can fit against the inner wall of the external coke tower.

[0012] Furthermore, a limit ring is installed at the end of the slide rod, and a spring is sleeved on the outside of the slide rod. One end of the spring is in contact with the side wall of the limit ring, and the other end of the spring is in contact with the side wall of the fixing rod.

[0013] Furthermore, a storage groove is provided on the upper wall of the scraper.

[0014] Furthermore, a protrusion is installed on the upper wall of the fixing rod, and a groove is opened on the lower wall of the scraper. The protrusion is inserted into the groove, and a ball is installed on the upper wall of the protrusion. The ball can fit against the inner wall of the groove.

[0015] Furthermore, a telescopic rod is installed on both the front and rear sides of the crossbar, and an auxiliary support wheel is installed on the other end of the telescopic rod. The auxiliary support wheel is in contact with the inner wall of the external coke tower.

[0016] The beneficial effects of this patent are:

[0017] Both the drive mechanism and the decoking mechanism in this device can change their positions under the action of the bidirectional electric push rod, so that they can be appropriately adjusted according to the inner diameter of the coke tower, thereby improving the applicability of this device. At the same time, this device uses a motor in the drive mechanism to drive the rotating sleeve to rotate, which moves the device inside the coke tower under the action of the top holding plate. Compared with the prior art that uses a telescopic rod for lifting, the movement is more convenient. Attached Figure Description

Detailed Implementation

[0022] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0023] See Figure 1 , Figure 2 , Figure 3 This is a schematic diagram of the structure of this patent. A vertical coke tower decoking device includes a crossbar 1 and a drive mechanism 2. A bidirectional electrically controlled push rod 3 is installed in the inner cavity of the crossbar 1. The bidirectional electrically controlled push rod 3 is electrically connected to an external power source. The output ends on both sides of the bidirectional electrically controlled push rod 3 are equipped with the drive mechanism 2. The drive mechanism 2 can fit against the inner wall of the external coke tower.

[0024] The drive mechanism 2 includes a fixed plate 21, a motor 22, a rotating sleeve 23 and a top holding plate 24. The fixed plate 21 is installed at the output end of the bidirectional electric push rod 3. The motor 22 is installed on the side wall of the fixed plate 21. The motor 22 is electrically connected to an external power source. The output end of the motor 22 passes through the side wall of the fixed plate 21 and is installed with the rotating sleeve 23. The top holding plate 24 is installed on the side wall of the rotating sleeve 23. The top holding plate 24 can fit against the inner wall of the external coke tower.

[0025] By setting a bidirectional electrically controlled push rod 3, the position of the drive mechanism 2 and the decoking mechanism 4 can be adjusted, so that this device can be applied to coke towers with different inner diameters to perform decoking operations on the inner wall of the coke tower.

[0026] This device uses a motor 22 to drive a rotating sleeve 23 to rotate, and the top support plate 24 on the outside of the rotating sleeve 23 serves as a drive wheel, thereby driving the device to move up and down inside the coke tower, which is very convenient.

[0027] A desiccation mechanism 4 is installed on the outer side of the output end of the bidirectional electric push rod 3, and the desiccation mechanism 4 is located above the drive mechanism 2;

[0028] The decoking mechanism 4 contacts the inner wall of the coke tower first, which can prevent the top holding plate 24 from contacting the coke on the inner wall of the coke tower and prevent slippage.

[0029] The decoking mechanism 4 includes a fixed rod 41, a through hole 42, a sliding rod 43, and a scraper 44. The side wall of the fixed rod 41 is provided with a connecting hole 5. The fixed rod 41 is installed on the outside of the output end of the bidirectional electric push rod 3 through the connecting hole 5. The side wall of the fixed rod 41 is provided with a through hole 42. The sliding rod 43 is slidably installed in the through hole 42. The upper wall of the sliding rod 43 is equipped with a scraper 44. The scraper 44 can fit against the inner wall of the external coke tower.

[0030] The outer wall of the scraper 44 in this paper is arc-shaped, which can completely fit the inner wall of the coke tower, so that the scraper 44 can remove coke from the inner wall of the coke tower during the movement of the device.

[0031] A limit ring 6 is installed at the end of the slide rod 43, and a spring 7 is sleeved on the outside of the slide rod 43. One end of the spring 7 is in contact with the side wall of the limit ring 6, and the other end of the spring 7 is in contact with the side wall of the fixing rod 41.

[0032] By using spring 7, a force can be applied to slide bar 43 towards the inner wall of coke tower, so that scraper 44 can be completely attached to the inner wall of coke tower, thereby improving the decoking effect of this device.

[0033] A storage groove 8 is provided on the upper wall of the scraper 44;

[0034] Storage tank 8 can collect the coke scraped off by scraper 44.

[0035] The upper wall of the fixed rod 41 is equipped with a protrusion 9, and the lower wall of the scraper 44 is provided with a groove 10. The protrusion 9 is inserted into the groove 10, and the upper wall of the protrusion 9 is equipped with a ball bearing 11, which can fit against the inner wall of the groove 10.

[0036] The cooperation between the protrusion 9 and the chute 10 can prevent the scraper 44 from tilting or tilting during the movement of this device, thus avoiding affecting the cleaning effect on the inner wall of the coke tower.

[0037] The front and rear sides of the crossbar 1 are each equipped with one end of a telescopic rod 12, and the other end of the telescopic rod 12 is equipped with an auxiliary support wheel 13. The auxiliary support wheel 13 is in contact with the inner wall of the external coke tower.

[0038] The telescopic rod 12 is equipped with bolts on its outer side. After the length of the telescopic rod 12 is adjusted, the adjusted telescopic rod 12 can be locked with the bolts so that its auxiliary support wheel 13 can fit against the inner wall of the coke tower to provide auxiliary support for the device and enable the device to move stably inside the coke tower.

[0039] When this patent is in operation, the device is first placed inside the coke tower. Then, the bidirectional electric push rod 3 is pushed out to adjust the position of the drive mechanism 2 and the coke removal mechanism 4 so that the top holding plate 24 and the scraper 44 are pressed against the inner wall of the coke tower. Then, the length of the telescopic rod 12 is adjusted so that the auxiliary support wheel 13 is in contact with the inner wall of the coke tower. Then, the motor 22 can be started, which drives the rotating sleeve 23 to rotate. The top holding plate 24 on the outside of the rotating sleeve 23 serves as the drive wheel, thereby driving the device to move up and down inside the coke tower.

[0040] During the movement of this device, scraper 44 will scrape and clean the coke on the inner wall of the coke tower. After cleaning, when the device returns to its original position, the operator can manually rotate the device horizontally and then continue to control the device to rise and fall to continue cleaning until the inner wall of the coke tower is completely cleaned.

[0041] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this patent. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
