Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal processing, in particular to a coking cleaning device. BACKGROUND

[0002] In the coal gasification process, the thermocouple is inserted into the furnace wall mounting hole to monitor the reaction temperature in real time, which is the core instrument to ensure the safe operation of the gasifier. However, the high temperature above 1300℃ in the furnace makes the thermocouple melt and deform, and the molten ash and slag condense along the hole, forming a dense coke layer on the inner wall of the mounting hole. This will block the mounting hole and hinder the insertion of the new thermocouple, so the coke layer cleaning work of the thermocouple mounting hole is usually needed before the periodic synchronous replacement of the thermocouple.

[0003] At present, manual coke cleaning is generally used, and the maintenance personnel hold a steel drill and a large hammer to repeatedly hammer the mounting hole at high temperature to crush the coke layer in the mounting hole. This manual coke cleaning method has a great labor intensity and low coke cleaning efficiency, which further leads to low thermocouple replacement efficiency. SUMMARY

[0004] The present application provides a coking cleaning device to solve the problem of high labor intensity and low thermocouple replacement efficiency in the prior art when replacing the thermocouple by manually cleaning the coke layer in the mounting hole.

[0005] The present application provides a coking cleaning device, which comprises a support, a coke cleaning rod movably arranged on the support, the coke cleaning rod having a connecting end and a free end, the free end being capable of extending out of or retracting into the support, a first driving member arranged on the support, the first driving member being drivingly connected with the coke cleaning rod to drive the coke cleaning rod to move relative to the support, and a transmission assembly arranged between the first driving member and the coke cleaning rod, the transmission assembly comprising a lever, the lever being rotatable relative to the support, the lever having oppositely arranged first and second ends, the first end being connected with the connecting end, and the first driving member driving the first or second end to move relative to the support to drive the free end to extend out of or retract into the support.

[0006] Further, the coking cleaning device further comprises a rod changing assembly arranged on the support, the rod changing assembly having a first opening and a plurality of mounting portions, the extension direction of the first opening being the same as the moving direction of the coke cleaning rod, the mounting portions being used for placing the coke cleaning rod, the first opening being located between the first end and the mounting portions, the first opening being correspondingly arranged with the first end, and being selectively communicated with any one of the mounting portions, and the first driving member being located at the end portion of the first opening to drive the coke cleaning rod in the mounting portion corresponding to the first opening to move.

[0007] Furthermore, the rod changing assembly includes: a roller, rotatably mounted on a support and located below the transmission assembly, the rotation axis of the roller being the same as the movement direction of the coke clearing rod, and multiple mounting grooves spaced circumferentially on the outer side wall of the roller, the extension direction of the mounting grooves being the same as the movement direction of the coke clearing rod, the mounting grooves being used to place the coke clearing rod, the coke clearing rod being able to move along the mounting grooves, the mounting grooves forming a mounting part; a second driving member, mounted on the support, the second driving member being drivenly connected to the roller to drive the roller to rotate relative to the support; and a housing, fixed on the support and fitted onto the outer periphery of the roller, the housing having openings at both ends, the first opening being located on the side wall of the housing facing the transmission assembly.

[0008] Furthermore, the outer casing has a second opening on the side wall away from the transmission component. The extension direction of the second opening is the same as the extension direction of the mounting groove. The length of the second opening along the axial direction of the outer casing is greater than or equal to the length of the descaling rod. A rotating plate assembly is also provided on the outer side wall of the outer casing. The rotating plate assembly is correspondingly provided with the second opening. The rotating plate assembly can open or block the second opening.

[0009] Furthermore, the rod changing assembly also includes a storage box, which is located below the housing. The storage box has a receiving cavity, and an inlet is located on the side of the storage box near the second opening. The inlet communicates with the receiving cavity, which is used to place the descaling rod. The inlet is corresponding to the second opening, and the extension direction of the inlet is the same as the extension direction of the second opening. The mounting groove has a notch on the side facing the housing, and the extension direction of the notch is the same as the extension direction of the mounting groove. The size of the circumferential notch along the housing is larger than the outer diameter of the descaling rod.

[0010] Furthermore, a cooling element is provided at the end of the storage box, and at least part of the cooling element is located inside the receiving cavity. The cooling element is used to reduce the temperature inside the receiving cavity.

[0011] Furthermore, the transmission assembly also includes a third driving member, which has a first fixed end and a first adjusting end disposed opposite to each other. The first fixed end is connected to the bracket, and the first adjusting end is movable relative to the first fixed end. The direction of movement of the first adjusting end is parallel to the direction of movement of the clearing rod. The first adjusting end is movably connected to a lever, and the lever is oscillating relative to the first adjusting end. The first driving member has a second fixed end and a second adjusting end disposed opposite to each other. The second fixed end is connected to the bracket, and the second adjusting end is movable relative to the second fixed end. The direction of movement of the second adjusting end is the same as the direction of movement of the clearing rod. The first adjusting end can selectively abut against either the first end or the second end.

[0012] Furthermore, the coke removal rod moves horizontally, and the coke removal device includes: a second vertical guide rail and a second sliding member. The second vertical guide rail is mounted on the support and located above the transmission assembly. The second sliding member is movably mounted on the second vertical guide rail. A third driving member is mounted on the second sliding member. The first vertical guide rail and the third vertical guide rail are respectively mounted on the support and are spaced apart from the second vertical guide rail at both ends of the transmission assembly along the moving direction of the coke removal rod. The third vertical guide rail is located between the first vertical guide rail and the second vertical guide rail. The first sliding member and two horizontal guide rails are respectively spaced apart vertically between the first vertical guide rail and the second vertical guide rail. One horizontal guide rail is corresponding to the first end, and the other horizontal guide rail is corresponding to the second end. The two horizontal guide rails are respectively connected to the first vertical guide rail and the third vertical guide rail. The first sliding member can move between the first vertical guide rail, the third vertical guide rail, and the two horizontal guide rails. The first driving member is mounted on the first sliding member.

[0013] Furthermore, the coking cleaning device also includes a controller, which is electrically connected to the first driving member, the third driving member, the first sliding member, and the second sliding member respectively. The controller drives the first sliding member to move along the first vertical guide rail, and the controller drives the second sliding member to move along the second vertical guide rail.

[0014] Furthermore, a first angle sensor and a second angle sensor are respectively provided on both sides of the first adjustment end. The first angle sensor and the second angle sensor are used to measure the angle between the first adjustment end and the lever. Both the first angle sensor and the second angle sensor are electrically connected to the controller.

[0015] Applying the technical solution of this invention, the support is placed near the mounting hole on the side wall of the gasifier. The first end of the lever is connected to the connecting end of the decoking rod. The first driving member can drive the first end or the second end to move relative to the support. The first end and the second end of the lever move in opposite directions to drive the free end to extend or retract from the support. Specifically, when it is necessary to decoke the mounting hole on the side wall of the gasifier, the first driving member can approach the first end. After aligning the decoking rod with the mounting hole, the first driving member can drive the first end to move relative to the support towards the gasifier. This can then drive the free end of the decoking rod to extend out of the support and repeatedly impact the mounting hole, thereby cleaning the coke layer inside the mounting hole. After the free end enters the mounting hole, the first driving member drives the second end to move relative to the support away from the gasifier. This indirectly drives the first end to move away from the gasifier. The first driving member then drives the free end to retract into the support, thus removing the free end from the mounting hole, completing the decoking cleaning work of the mounting hole. Subsequently, the operator can install a new thermocouple into the cleaned mounting hole. Compared to manually hammering the steel rod with a sledgehammer or manually pulling the steel rod out of the installation hole, this application, through the above-mentioned setting, not only improves the convenience of coke removal, saves manpower, and increases the efficiency of coke removal, thereby improving the efficiency of thermocouple replacement, but also reduces the contact between workers and the high-temperature gasifier and the high-temperature coke removal rod, avoiding the risk of burns and improving the safety of coke removal.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 3 As shown, this embodiment of the invention provides a coking removal device, which includes a support 10, a coking removal rod 20, a first driving member 30, and a transmission assembly. The coking removal rod 20 is movably mounted on the support 10 and has a connecting end 201 and a free end 202, the free end 202 being able to extend or retract from the support 10. The first driving member 30 is mounted on the support 10 and is drivenly connected to the coking removal rod 20 to drive the coking removal rod 20 to move relative to the support 10. The transmission assembly is disposed between the first driving member 30 and the coking removal rod 20 and includes a lever 41, which is rotatable relative to the support 10. The lever 41 has a first end 411 and a second end 412 oppositely disposed. The first end 411 is connected to the connecting end 201. The first driving member 30 drives the first end 411 or the second end 412 to move relative to the support 10, thereby driving the free end 202 to extend or retract from the support 10.

[0031] In this embodiment, the descaling rod 20 is a steel rod.

[0032] Applying the technical solution of this invention, the support 10 is placed near the mounting hole on the side wall of the gasifier 100. The first end of the lever 41 is connected to the connecting end of the coke-removing rod 20. The first driving member 30 can drive the first end 411 or the second end 412 to move relative to the support 10. The first end 411 and the second end 412 of the lever 41 move in opposite directions to drive the free end 202 to extend or retract from the support 10. Specifically, when it is necessary to remove coke from the mounting hole on the side wall of the gasifier 100, the first driving member 30 can approach the first end 411. After aligning the coke-removing rod 20 with the mounting hole, the first driving member 30 can drive the first end 411 to move relative to the support 10 toward the gasifier 100. This can then drive the free end of the coke-removing rod 20 to extend out of the support 10 and repeatedly strike the mounting hole, thereby cleaning the coke layer in the mounting hole. After the free end 202 enters the mounting hole, the second end 412 is driven by the first driving component 30 to move away from the gasifier 100 relative to the support 10. This indirectly drives the first end 411 to move away from the gasifier 100. The first driving component 30 then drives the free end 202 to retract into the support 10, thus removing the free end 202 from the mounting hole, completing the coking cleaning of the mounting hole. Afterwards, the worker can install a new thermocouple into the cleaned mounting hole. Compared to manually hammering the steel rod with a sledgehammer or manually pulling the steel rod out of the mounting hole, this application, through the above-mentioned setting, not only improves the convenience of coking cleaning, saves manpower, and increases the efficiency of coking cleaning, thereby improving the efficiency of thermocouple replacement, but also reduces the contact between workers and the high-temperature gasifier 100 and the high-temperature coking rod 20, avoiding the risk of burns and improving the safety of coking cleaning.

[0033] Among them, gasifier 100 is a Texaco gasifier.

[0034] like Figure 1 and Figure 2 As shown, the coking removal device also includes a rod replacement assembly 50, which is mounted on the bracket 10. The rod replacement assembly 50 has a first opening 531 and multiple mounting portions. The extension direction of the first opening 531 is the same as the movement direction of the coking removal rod 20. The mounting portions are used to place the coking removal rod 20. The first opening 531 is located between the first end 411 and the mounting portion. The first opening 531 is correspondingly arranged with the first end 411 and can selectively communicate with any one of the mounting portions. The first driving member 30 is located at the end of the first opening 531 to drive the coking removal rod 20 in the mounting portion corresponding to the first opening 531 to move. In this way, when the coking removal rod 20 is used up or damaged, other mounting portions can be replaced and communicated with the first opening 531 for timely replacement without manual replacement, improving the continuity of coking removal and further improving the replacement efficiency of thermocouples.

[0035] There are no restrictions on how the multiple mounting parts are connected to the first opening 531. Multiple robotic arms can be used to connect to the multiple mounting parts respectively, or the positions of the multiple mounting parts can be changed by using a single or multiple grippers.

[0036] Furthermore, the rod changing assembly 50 includes a roller 51, a second drive element 52, and a housing 53. The roller 51 is rotatably mounted on the support 10 and located below the transmission assembly, i.e., below the lever 41. The rotation axis of the roller 51 is the same as the movement direction of the coke removal rod 20. Multiple mounting grooves 511 are provided circumferentially on the outer wall of the roller 51. The extension direction of the mounting grooves 511 is the same as the movement direction of the coke removal rod 20. One mounting groove 511 is used to place one coke removal rod 20. The coke removal rod 20 can move along the mounting groove 511 toward the gasifier 100 or away from the gasifier 100. The mounting groove 511 can continue to guide the movement direction of the coke removal rod 20 to ensure the accuracy of coke removal and prevent the coke removal rod 20 from hitting the furnace wall of the gasifier 100. The mounting groove 511 forms a mounting part. The length of the mounting groove 511 is greater than or equal to the length of the coke removal rod 20 so that the coke removal rod 20 can be completely placed into the mounting groove 511 to prevent it from protruding from the ends of the roller 51 and the outer shell 53, thus ensuring the normal rotation of the roller 51. The mounting groove 511 has a notch 5111 on the side facing the housing 53. The notch 5111 extends in the same direction as the mounting groove 511. The size of the circumferential notch 5111 along the housing 53 is larger than the outer diameter of the descaling rod 20.

[0037] like Figure 1As shown, the second driving member 52 is mounted on the bracket 10 and is driven to drive the roller 51 to rotate relative to the bracket 10. The outer shell 53 is fixed on the bracket 10 and sleeved on the outer circumference of the roller 51. Along the circumference of the roller 51, there is a gap between the roller 51 and the outer shell 53. The size of the gap is smaller than the diameter of the coke removal rod 20. In this way, the outer shell 53 can prevent the coke removal rod 20 from coming out of the mounting groove 511 when the roller 51 rotates, thus ensuring the stability of the coke removal rod 20 placed in the mounting groove 511. Both ends of the outer casing 53 have openings to facilitate the extension and retraction of the coke removal rod 20. The first opening 531 is located on the side wall of the outer casing 53 facing the transmission assembly, i.e., the top of the outer casing 53. Thus, when it is necessary to clean the coke in the mounting hole of the thermocouple, the second drive member 52 can drive the roller 51 to rotate, thereby driving multiple mounting slots 511 to rotate. When one of the mounting slots 511 containing the unused coke removal rod 20 rotates to communicate with the first opening 531, i.e., it is located below the first opening 531, and the notch 5111 at least partially overlaps with the first opening 531, the second drive member 52 stops driving the roller 51 to rotate. Then, the first end 411 of the lever 41 is connected to the connecting end 201 of the coke removal rod 20 in the mounting slot 511 communicating with the first opening 531. Then, the first drive member 30 drives the lever 41 to swing, thereby realizing the extension and retraction of the coke removal rod 20 in the mounting slot 511, thus completing the cleaning of the coke layer in the mounting hole. After the descaling rod 20 returns to the mounting slot 511 after completing its work, the second driving component 52 drives the roller 51 to rotate, switching other mounting slots 511 to connect with the first opening 531 for subsequent descaling work.

[0038] With the above setup, through the cooperation of the roller 51, the second drive component 52 and the housing 53, the operator can place multiple cleaning rods 20 in the mounting slots 511 at one time for subsequent cleaning work. The operator can wait until all or part of the cleaning rods 20 are used up before replacing them all at once, reducing the number of times the rods need to be replaced manually and reducing the workload of the operator.

[0039] In this embodiment, the coke removal rod 20 extends and moves horizontally. The thermocouple mounting hole is typically located on the side wall of the gasifier 100, facilitating the alignment of the coke removal rod 20 with the mounting hole for coke removal. The roller 51, mounting groove 511, and outer casing 53 all extend horizontally. The number of mounting grooves 511 is not limited and can be selected according to operational requirements.

[0040] Specifically, the second driving component 52 is a motor. A rotating shaft is provided inside the roller 51, and the extension direction of the rotating shaft is the same as the extension direction of the roller 51. The roller 51 is connected to the bracket 10 through the rotating shaft. Both ends of the rotating shaft are rotatably connected to the bracket 10. The roller 51 is fixedly sleeved on the outer circumference of the rotating shaft. The second driving component 52 is driven by the rotating shaft to drive the rotating shaft to rotate, thereby driving the roller 51 to rotate.

[0041] Furthermore, the outer casing 53 has a second opening on its side wall away from the transmission assembly, i.e., the second opening is located at the bottom of the outer casing 53. The extension direction of the second opening is the same as the extension direction of the mounting groove 511. The length of the second opening along the axial direction of the outer casing 53 is greater than or equal to the length of the coke cleaning rod 20. A rotating plate assembly is also provided on the outer side wall of the outer casing 53. The rotating plate assembly is correspondingly arranged with the second opening and can open or close the second opening. With the above arrangement, when the mounting groove 511 containing the used, high-temperature coke cleaning rod 20 rotates to the bottom of the outer casing 53 and connects with the second opening, the rotating plate assembly is driven to open the second opening, allowing the used coke cleaning rod 20 to detach from the mounting groove 511, thus facilitating the subsequent replacement of a new coke cleaning rod 20.

[0042] like Figure 1 As shown, the rod changing assembly 50 also includes a storage box 54, which is located below the outer casing 53. The storage box 54 has a receiving cavity, and an inlet is located on the side of the storage box 54 near the second opening. The inlet communicates with the receiving cavity, which is used to hold the coke removal rod 20. The inlet is corresponding to the second opening, and the extension direction of the inlet is the same as that of the second opening. The size of the inlet is adapted to the coke removal rod 20 to ensure that the coke removal rod 20 falling from the second opening can directly enter the receiving cavity through the inlet. In this way, there is no need to manually collect the used coke removal rod 20 one by one. It can be collected in the storage box 54 and processed regularly, which further improves the convenience of the staff, reduces the workload of the work team, and reduces the risk of burns to the staff from the high temperature of the coke removal rod 20, thus improving the safety of the work team.

[0043] In some embodiments, the storage box 54 is disposed below the support 10, and a telescopic cylinder is provided at the bottom of the storage box 54. The height of the components on the support 10 is adjusted by the telescopic cylinder, so that the coke removal rod 20 can be adapted to the mounting holes of different heights. A roller 14 is installed at the bottom of the telescopic cylinder to facilitate the relative position between the moving device and the gasifier 100.

[0044] In other embodiments, the storage bin 54 is fixed inside the bracket 10, and the telescopic cylinder and roller 14 are both fixed to the bottom surface of the bracket 10.

[0045] like Figure 1As shown, a cooling element 55 and an infrared thermometer are provided at the end of the storage box 54. At least part of the cooling element 55 is located inside the receiving cavity, and the cooling element 55 is used to reduce the temperature inside the receiving cavity.

[0046] Specifically, the cooling component 55 is a fan that uses air cooling. It is located at the end of the storage box 54 near the free end 202 of the coke removal rod 20. The fan is used to blow air towards the coke removal rod 20. When the infrared thermometer detects that the temperature inside the cavity is higher than 100 degrees Celsius, the fan can automatically start blowing air towards the coke removal rod 20 to cool it down.

[0047] like Figure 1 As shown, the transmission assembly also includes a third driving member 42. The third driving member 42 has a first fixed end and a first adjusting end arranged opposite to each other. The first fixed end is connected to the bracket 10. The first adjusting end can move relative to the first fixed end. The moving direction of the first adjusting end is parallel to the moving direction of the coke removal rod 20, so as to drive the lever 41 to move relative to the bracket 10. The first adjusting end is movably connected to the middle of the lever 41. In this way, the first adjusting end can drive the lever 41 to move along the moving direction of the coke removal rod 20, and then adjust its position on the bracket 10 according to the position of the free end 202 of the coke removal rod 20 in the mounting hole on the side wall of the gasifier 100. For example, it can be understood that when the free end 202 just enters the mounting hole, the connecting end 201 is far away from the gasifier 100. At this time, the first adjusting end moves in the direction away from the gasifier 100, and the position of the lever 41 also corresponds to the connecting end 201. When the free end 202 enters the mounting hole deeply or has already pierced it, the connecting end 201 is closer to the gasifier 100. At this time, the first adjusting end moves towards the gasifier 100, and the lever 41 also moves to a position close to the gasifier 100 to avoid excessive swinging of the two ends of the lever 41. The lever 41 can swing relative to the first adjusting end, and the middle part of the lever 41 is hinged to the first adjusting end. The first driving member 30 has a second fixed end and a second adjusting end arranged opposite to each other. The second fixed end is connected to the bracket 10, and the second adjusting end can move relative to the second fixed end. The moving direction of the second adjusting end is the same as the moving direction of the coke removal rod 20. The first adjusting end can selectively abut against the first end 411 or the second end 412. By extending or retracting the second adjusting end, it can impact the first end 411 or the second end 412, thereby driving the lever 41 to swing, thus driving the coke removal rod 20 to be driven into or out of the mounting hole.

[0048] like Figure 1 and Figure 3As shown, the coking removal device includes a second vertical guide rail 12 and a second sliding member, a first vertical guide rail 11 and a third vertical guide rail 15, a first sliding member, and two horizontal guide rails. The second vertical guide rail 12 is mounted on the support 10 and located above the transmission assembly. The second sliding member is movably mounted on the second vertical guide rail 12, and a third driving member 42 is mounted on the second sliding member. The first vertical guide rail 11 and the third vertical guide rail 15 are respectively mounted on the support 10 and are spaced apart from the second vertical guide rail 12 at both ends of the transmission assembly along the moving direction of the coking removal rod 20. The third vertical guide rail 15 is located between the first vertical guide rail 11 and the second vertical guide rail 12 and is parallel to them. Two horizontal guide rails are vertically spaced between the first vertical guide rail 11 and the second vertical guide rail 12. One horizontal guide rail corresponds to the first end 411, and the other horizontal guide rail corresponds to the second end 412. The two horizontal guide rails are parallel to each other and are connected to the first vertical guide rail 11 and the third vertical guide rail 15, respectively. The first sliding member can move between the first vertical guide rail 11, the third vertical guide rail 15, and the two horizontal guide rails. The first driving member 30 is mounted on the first sliding member. With this configuration, the first driving member 30 can move along with the lever 41 via the first sliding member, ensuring that the position between the first driving member 30 and the lever 41 is always appropriate. This avoids the first driving member 30 being too far from the lever 41, failing to make contact, or having an excessively long single driving time, thus ensuring the driving efficiency of the first driving member 30.

[0049] The first vertical guide rail 11, the second vertical guide rail 12 and the third vertical guide rail 15 are all located above the rod changing assembly 50.

[0050] like Figure 1 As shown, the first end 411 is inserted into the connecting end 201. The end of the first end 411 facing the desiccant rod 20 has a plug-in block. The connecting end 201 has a plug-in hole at the position corresponding to the plug-in block. The diameter of the plug-in hole is slightly larger than the diameter of the plug-in block so that the plug-in block can have a certain degree of freedom of movement within the plug-in hole, preventing the lever 41 from jamming with the desiccant rod 20. When the lever 41 needs to connect to the desiccant rod 20, the second sliding member drives the third driving member 42 to move downwards and closer to the desiccant rod 20, thereby driving the lever 41 to move downwards so that the plug-in block is inserted into the plug-in hole. When the desiccant rod 20 has finished working, the second sliding member drives the third driving member 42 to move upwards and away from the desiccant rod 20, thereby removing the plug-in block from the plug-in hole.

[0051] The first driving component 30 is a pneumatic hammer, one end of which is connected to an air compressor 80. An infrared laser is mounted on the pneumatic hammer, aligned with the thermocouple mounting hole to prevent it from deviating from the center and damaging the furnace bricks of the gasifier 100. The first sliding component can be an electrically controlled trolley, which is controlled by an electrical control system to slide between different tracks; this is existing technology and will not be elaborated upon here.

[0052] Specifically, the bracket 10 includes multiple support rods 13, which extend in the horizontal and vertical directions respectively and are staggered to form a cuboid frame.

[0053] like Figure 3 As shown, the coking removal device also includes a controller 70. The controller 70 is electrically connected to the first drive component 30, the third drive component 42, the first sliding component, the second sliding component, the rotating plate assembly, the cooling component 55, and the infrared thermometer. The controller 70 drives the first sliding component to move along the first vertical guide rail 11, the third vertical guide rail 15, and the two horizontal guide rails. The controller 70 also drives the second sliding component to move along the second vertical guide rail 12. The controller 70 improves the automation level of the device, enhances the convenience of coking removal, further reduces manual operation steps and work, reduces the workload of workers, and improves the safety of coking removal.

[0054] like Figure 1 and Figure 3 As shown, a first angle sensor 61 and a second angle sensor 62 are respectively provided on both sides of the first adjustment end. The first angle sensor 61 and the second angle sensor 62 are used to measure the angle between the first adjustment end and the lever. The first angle sensor 61 and the second angle sensor 62 are both electrically connected to the controller 70. When the first drive member 30 strikes the lever 41, when the first angle sensor 61 and the second angle sensor 62 detect that the angle between the lever 41 and the third drive member 42 exceeds the preset value, they transmit a signal to the controller 70. The controller 70 controls the first drive member 30 to stop working and controls the extension and retraction of the third drive member 42. After the third drive member 42 is adjusted back to the preset value in time, the first drive member 30 will also continue to adjust by following the position of the lever 41 through the horizontal guide rail. Then, the first drive member 30 continues to perform the desiccant removal work to ensure that the angle between the lever 41 and the third drive member 42 is always at a suitable angle.

[0055] In this embodiment, the angle sensor can be a position switch. The preset value of the angle between the lever 41 and the third drive member 42 is between 80° and 100°.

[0056] When replacing thermocouples using the coking removal device provided in this application, first adjust the height of the device using roller 14 and telescopic cylinder. When the height of the first opening is adjusted to be close to the position of the mounting hole, control the second slider via controller 70 to drive the insertion block on lever 41 to descend into the insertion hole of the coking removal rod 20. At this time, all components of the device are located... Figure 1 Once the preparations are complete, the controller 70 controls the third drive component 42 to retract toward the gasifier 100 until the free end 202 approaches or abuts against the mounting hole. During this process, the first drive component 30 and the lever 41 move toward the gasifier 100. Then, the controller 70 operates, striking the first end 411 of the lever 41, which in turn causes the free end 202 to repeatedly impact the mounting hole until it can no longer be drilled (indicating that the coke rod 20 may be damaged) or the mounting hole has been cleared. Figure 3 In the state shown, the first drive component 30 stops working. It then moves to the second end 412 via the first slider and the third vertical guide rail 15. By striking the second end 412, the coke-cleaning rod 20 is retracted from the mounting hole into the mounting slot 511. During this process, the first drive component 30 and lever 41 move away from the gasifier 100. Subsequently, the controller 70 controls the third drive component 42 to move upward via the second slider, causing the insertion block to move out of the insertion hole. Then, the second drive component 52 is activated, driving the drum 51 to rotate, replacing the coke-cleaning rod 20, and the previous preparatory work continues. At this point, the state of each component returns to normal. Figure 1 .
