Description

Technical Field

[0001] This utility model relates to a mechanical coke removal device, specifically a mechanical coke removal device in a carbon conversion reactor, and belongs to the technical field of mechanical coke removal equipment. Background Technology

[0002] As is well known, in high-temperature carbon conversion reactions, carbon in the reactor is prone to hardening and coking when exposed to high temperatures within the reaction range. Coking tends to adhere to the sidewalls of the reactor, which can affect the continuous and stable operation of the reaction over a long period of time. Mechanical coking removal devices are auxiliary devices used in carbon conversion reactors to clean the carbon deposits and coking inside the reactor, making it easier to use. They have been widely used in the field of mechanical coking removal equipment technology.

[0003] A mechanical descaling device for a carbon conversion reactor disclosed in Chinese Patent Application Publication CN221714283U includes two plates, two sliding rods fixed between the side walls of the two plates, and a threaded rod rotatably connected between the side walls of the two plates. A first motor is located on the top of the plates, and the output shaft of the first motor is connected to the threaded rod. This technical solution is more stable, has a larger cleaning area, and is less prone to dead corners. However, this technical solution can only scrape and clean the inner wall of the carbon conversion reactor by moving the cleaning plate up and down. Since the inner wall of the carbon conversion reactor may be irregularly shaped, the cleaning end of the cleaning plate cannot make close contact with the inner wall of the carbon conversion reactor, which will result in cleaning dead corners on the inner wall of the carbon conversion reactor, thus affecting the descaling effect of the mechanical descaling device.

[0004] Therefore, a mechanical decoking device for a carbon conversion reactor is proposed here. Utility Model Content

[0005] This invention proposes a mechanical descaling device for a carbon conversion reactor to solve the problem in the prior art that the cleaning end of the cleaning plate cannot make close contact with the inner wall of the carbon conversion reactor.

[0006] This utility model is achieved through the following technical solution: a mechanical coking removal device in a carbon conversion reactor, including a coking removal turntable, wherein a pushing and cleaning mechanism is provided both inside and outside the coking removal turntable;

[0007] The sweeping mechanism includes electrically operated telescopic rods arranged in a circular pattern at equal intervals. The outer surface of the descaling turntable has mounting slots arranged in a circular pattern at equal intervals. The sides of several electrically operated telescopic rods that are close to each other are fixedly connected to the inner walls of several mounting slots. Each telescopic end of the electrically operated telescopic rod is fixedly connected to a pusher disc. Several pusher discs are slidably connected to the interiors of several mounting slots. The sides of several pusher discs that are far apart from each other are fixedly connected to pressure sensors arranged in a circular pattern at equal intervals. Several groups of pressure sensors are signal-connected to several electrically operated telescopic rods via a PLC controller. The sensing end of each group of pressure sensors is fixedly connected to a telescopic guide rod and a compression spring. The outer surfaces of several telescopic guide rods are in contact with the inner walls of several compression springs. A sweeping brush is fixedly connected to the telescopic end of each telescopic guide rod and the far ends of several compression springs.

[0008] A movable rotating component is provided inside the coke removal turntable, above the coke removal turntable, and below the coke removal turntable. A driving component is provided inside the coke removal turntable and above the coke removal turntable.

[0009] The movable rotating assembly includes a sliding positioning rod. A guide cylinder is fixedly connected to the inner wall of the descaling turntable. The sliding positioning rod is slidably connected to the inside of the guide cylinder and rotatably connected to the inside of the guide cylinder. A fixed plate is fixedly connected to both the top and bottom ends of the sliding positioning rod. The outer surface of the sliding positioning rod is provided with equidistant circumferentially arranged spiral grooves. Equidistant circumferentially arranged sliding balls are rotatably connected to the inside of the guide cylinder. Several of the sliding balls slide along the inner cavities of several spiral grooves respectively.

[0010] The drive assembly includes two fixed frames, the bottom surface of each fixed frame is fixedly connected to the upper surface of one of the fixed disks, and a drive telescopic rod is fixedly connected to the inner wall of each fixed frame. The telescopic end of each drive telescopic rod passes through one of the fixed disks and extends to the bottom of one of the fixed disks.

[0011] The telescopic ends of the two drive telescopic rods are fixedly connected to a lifting ring. The upper surface of the coke clearing turntable is provided with a lifting groove, and the lifting ring is rotatably connected to the inside of the lifting groove.

[0012] The outer surface of the descaling turntable is fixedly connected with equidistantly arranged circumferential limiting cylinders. Several limiting cylinders are respectively connected to several mounting slots, and the outer surfaces of several compression springs are respectively in contact with the inner walls of several limiting cylinders.

[0013] Two reinforcing rings are fixedly connected to the outer surface of the sliding positioning rod, and the two reinforcing rings are fixedly connected to the sides of the two fixed plates that are close to each other.

[0014] This invention provides a mechanical decoking device for a carbon conversion reactor, which has the following beneficial effects:

[0015] 1. This mechanical decoking device in a carbon conversion reactor can move within the reactor via a decoking turntable, facilitating the movement of an electrically driven telescopic rod within an installation slot. The push plate, pressure sensor, telescopic guide rod, and compression spring at the telescopic end of the electric telescopic rod allow for easy detection of the pressure applied to them by the pressure sensor. The cleaning brush contacts and squeezes against the inner wall of the carbon conversion reactor, and the pressure exerted by the cleaning brush on the reactor's inner wall can be adjusted by controlling the electric telescopic rod. This ensures close contact between the cleaning brush and the reactor's inner wall, improving the cleaning effect of the mechanical decoking device.

[0016] 2. The mechanical decoking device in the carbon conversion reactor can drive the decoking turntable to slide along the sliding positioning rod via a drive assembly. This allows multiple rolling sliding balls to be installed inside the guide cylinder fixed to the inner wall of the decoking turntable. Multiple spiral grooves are opened outside the sliding positioning rod, so that the drive assembly can push the decoking turntable up and down, causing the multiple rolling sliding balls to slide within the multiple spiral grooves. This allows the decoking turntable to slide and rotate along the sliding positioning rod, enabling the cleaning brush of the mechanical decoking device to move and rotate to clean the inner wall of the carbon conversion reactor, thereby further improving the cleaning effect of the mechanical decoking device.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0028] Please see Figures 1-4 This utility model embodiment provides a mechanical decoking device in a carbon conversion reactor, including a decoking turntable 1, and a pushing and cleaning mechanism 2 is provided both inside and outside the decoking turntable 1.

[0029] Please refer to this carefully. Figure 1 , Figure 3 and Figure 4The sweeping mechanism 2 includes electrically operated telescopic rods 202 arranged in a circular pattern at equal intervals. The outer surface of the descaling turntable 1 has mounting slots 201 arranged in a circular pattern at equal intervals. The sides of several electrically operated telescopic rods 202 that are close to each other are fixedly connected to the inner walls of several mounting slots 201. Each telescopic end of the electrically operated telescopic rod 202 is fixedly connected to a push plate 203. Several push plates 203 are slidably connected to the interiors of several mounting slots 201. The sides of several push plates 203 that are far apart from each other are fixedly connected to pressure sensors 204 arranged in a circular pattern at equal intervals. The pressure sensors 204 are devices or apparatuses that can sense pressure signals and convert them into usable output electrical signals according to a certain rule. The model of the pressure sensors 204 is MPX2010. Several sets of pressure sensors 204 are connected to several PLC controllers. Each set of pressure sensors 204 has a fixed connection to a telescopic guide rod 205 and a compression spring 206 at its sensing end. This structure allows the guide rod to slide and extend within the sliding cylinder. The outer surfaces of several telescopic guide rods 205 are in contact with the inner walls of several compression springs 206. A cleaning brush 207 is fixedly connected to the telescopic end of each telescopic guide rod 205 and the ends of several compression springs 206 that are far apart from each other. The outer surface of the descaling turntable 1 is fixedly connected to a limiting cylinder 5 arranged in a circular pattern at equal intervals. Several limiting cylinders 5 are connected to several mounting slots 201. The outer surfaces of several compression springs 206 are in contact with the inner walls of several limiting cylinders 5. Through the limiting cylinders 5, the extension and retraction of the telescopic guide rods 205 and compression springs 206 can be guided and limited, thereby improving the extension stability of the cleaning brush 207.

[0030] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3A movable rotating assembly 3 is provided inside, above, and below the desiccant removal turntable 1. A driving assembly 4 is provided inside and above the desiccant removal turntable 1. The movable rotating assembly 3 includes a sliding positioning rod 302. A guide cylinder 304 is fixedly connected to the inner wall of the desiccant removal turntable 1. The sliding positioning rod 302 is slidably connected to the inside of the guide cylinder 304 and rotatably connected to the inside of the guide cylinder 304. A fixed plate 30 is fixedly connected to both the top and bottom ends of the sliding positioning rod 302. 1. The outer surface of the sliding positioning rod 302 is provided with spiral grooves 303 arranged in equal distances in a circular pattern. The guide cylinder 304 is rotatably connected with sliding balls 305 arranged in equal distances in a circular pattern. Several sliding balls 305 slide along the inner cavity of several spiral grooves 303 respectively. By using the desiccant removal turntable 1 to move the guide cylinder 304 up and down along the sliding positioning rod 302, the sliding balls 305 can slide along the inner cavity of the spiral grooves 303, thereby facilitating the desiccant removal turntable 1 to move and rotate up and down along the sliding positioning rod 302 with the guide cylinder 304.

[0031] Please refer to this carefully. Figure 1 Two reinforcing rings 6 are fixedly connected to the outer surface of the sliding positioning rod 302. The two reinforcing rings 6 are fixedly connected to the two fixed disks 301 respectively on the side that is far apart from each other. The reinforcing rings 6 are fixed at the connection between the sliding positioning rod 302 and the fixed disk 301, thereby improving the connection stability between the sliding positioning rod 302 and the fixed disk 301.

[0032] Please refer to this carefully. Figure 1 and Figure 2 The drive assembly 4 includes two fixed frames 401. The bottom surface of each fixed frame 401 is fixedly connected to the upper surface of one of the fixed disks 301. A drive telescopic rod 402 is fixedly connected to the inner wall of each fixed frame 401. The telescopic end of each drive telescopic rod 402 passes through one of the fixed disks 301 and extends to the bottom of one of the fixed disks 301. The fixed frames 401 enable the drive telescopic rod 402 to be fixedly installed above the fixed disk 301, so as to provide power for the desiccant turntable 1 to move up and down.

[0033] Please refer to this carefully. Figure 2 and Figure 3The telescopic ends of the two drive telescopic rods 402 are fixedly connected to a lifting ring 403. The upper surface of the coke clearing turntable 1 is provided with a lifting groove 404. The lifting ring 403 is rotatably connected to the inside of the lifting groove 404. By using the lifting ring 403 fixed by the telescopic ends of the two drive telescopic rods 402, the lifting ring 403 can be locked into the lifting groove 404 opened on the coke clearing turntable 1, so as to facilitate the rotation of the lifting ring 403 in the lifting groove 404, and further facilitate the coke clearing turntable 1 to move up and down and rotate along the sliding positioning rod 302.

[0034] In use, the electric telescopic rod 202, pressure sensor 204, and drive telescopic rod 402 are first connected to a power source. When the mechanical decoking device is needed to clean the carbon deposits on the inner wall of the carbon conversion reactor, the two fixed plates 301 of the mechanical decoking device are first manually connected to the inner wall of the carbon conversion reactor. This allows the mechanical decoking device to be stably installed inside the carbon conversion reactor to clean the carbon deposits on the inner wall of the carbon conversion reactor.

[0035] Next, by controlling the drive telescopic rod 402 fixed on the fixed plate 301 by the fixed bracket 401, the two drive telescopic rods 402 can be used to push the lifting ring 403 to move. Since the lifting groove 404 is opened on the desiccant turntable 1, the lifting ring 403 can push the desiccant turntable 1 and the guide cylinder 304 to move along the sliding positioning rod 302 in the lifting groove 404. Since multiple spiral grooves 303 are opened outside the sliding positioning rod 302, and multiple rolling sliding balls 305 are set in the guide cylinder 304, the desiccant turntable 1 can move up and down along the sliding positioning rod 302 while the multiple sliding balls 305 slide along the multiple spiral grooves 303, so that the desiccant turntable 1 can rotate along the sliding positioning rod 302, thereby allowing the lifting ring 403 to rotate in the lifting groove 404.

[0036] Then, multiple mounting slots 201 are made on the outer surface of the descaling turntable 1 to fix the push electric telescopic rod 202 inside the mounting slots 201. By controlling the push electric telescopic rod 202 to drive the push disk 203 to move, the cleaning brush 207 can be extended outward until its cleaning end contacts and squeezes the inner wall of the carbon conversion reactor for cleaning. Multiple pressure sensors 204 between the push disk 203, the telescopic guide rod 205, and the compression spring 206 can be used to easily detect the contact squeezing force of the cleaning brush 207 against the inner wall of the carbon conversion reactor. The pressure sensor 204 is indirectly fixed to the cleaning brush 207 via a telescopic guide rod 205 and a compression spring 206. This allows the PLC controller to control the electric telescopic rod 202 to push the push disk 203, which in turn causes the telescopic guide rod 205 and the compression spring 206 to extend and retract, thus adjusting the contact pressure of the cleaning brush 207 on the inner wall of the carbon conversion reactor. This enables multiple cleaning brushes 207 that move up and down and rotate along the sliding positioning rod 302 to clean the irregular carbon deposits and coke on the inner wall of the conversion reactor, improving the cleaning effect of the mechanical coke removal device.
