Description

Technical Field

[0001] The present invention relates to the loading and unloading of catalysts, and more particularly to a broken cutter head and a catalyst caking breaking device using the cutter head. Background Art

[0002] During the operation of unloading severely caked catalysts in a reactor, it is often encountered that the catalysts and other materials are severely caked and coked. At present, the breaking and unloading operation of the caking crusher must be carried out manually with a pickaxe in a nitrogen environment, which requires a large amount of manpower, material resources and working hours. Moreover, in a harsh working environment, the safety of the operators cannot be well guaranteed, which has a serious impact on the construction progress and construction safety. Therefore, the commonly used crushing devices in the current chemical industry are used to break and remove the caked catalysts.

[0003] The existing catalyst crushing devices generally use an air pipe or a rotating cutter head to break the caked materials in the reactor. When the materials in the reactor are severely caked, the speed of breaking with the air pipe is relatively slow and the construction time is long. The crushing method of the cutter head is to directly make the rotating cutter head contact the caked materials for crushing. When the inside of the reactor is severely caked, the drive shaft of the cutter head will bear a great radial load, which is likely to cause cracking at the connection between the cutter head and the drive shaft, or damage to the shaft seat of the drive shaft. For this reason, a broken cutter head and a catalyst caking breaking device using the cutter head are proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a broken cutter head and a catalyst caking breaking device using the cutter head to solve the problem that there are relatively large defects in the two commonly used crushing devices when the caking in the reactor is severe.

[0005] The present invention specifically adopts the following technical solutions to achieve the above object:

[0006] A broken cutter head and a catalyst caking breaking device using the cutter head, including a lifting hydraulic rod, the telescopic end of the lifting hydraulic rod is vertically downward and fixedly installed with a transmission box, a transmission motor is fixedly installed inside the transmission box, the output shaft of the transmission motor is downward and fixedly installed with a movable plate, a suspension bracket is fixedly installed at the bottom of the movable plate, a three-pronged cutter holder is fixedly installed at the bottom end of the suspension bracket, and drive cutter head assemblies are arranged at the three ends of the three-pronged cutter holder, and the three drive cutter head assemblies are arranged in a staggered manner;

[0007] The driving cutter head assembly is used to perform multi-position cutting on the caked catalyst driven by the lifting hydraulic rod. The driving cutter head assembly includes a tool mounting base fixedly sleeved on one end of the three-pronged tool rest. One end of the tool mounting base is fixedly installed with a vertical tool rest, and a vertical blunt cutter is fixedly installed on the vertical tool rest. The bottom of the tool mounting base is fixedly installed with an adjusting electric push rod horizontally. The telescopic end of the adjusting electric push rod faces away from the vertical blunt cutter and is fixedly installed with an assembly plate. One side of the assembly plate is fixedly installed with a pre-tightening spring rod horizontally. The telescopic end of the pre-tightening spring rod is fixedly installed with a limiting plate. One side of the limiting plate is fixedly installed with a hanging claw. The bottom of the hanging claw is fixedly installed with an L-shaped transverse tool rest. The bottom of the end of the L-shaped transverse tool rest facing the vertical blunt cutter is fixedly installed with a wedge-shaped transverse cutter. The top of the tool mounting base is fixedly installed with a height-adjusting electric push rod. The telescopic end of the height-adjusting electric push rod is vertically upward and is fixedly installed with a connecting frame. On the side of the connecting frame facing away from the vertical blunt cutter, a plurality of horizontally arranged scraping telescopic rods are fixedly installed. The telescopic ends of the plurality of scraping telescopic rods are fixedly installed with the same vertically arranged wedge-shaped scraper. A lifting chute is formed on the side of the wedge-shaped scraper facing the vertical blunt cutter. The L-shaped transverse tool rest is slidably installed inside the lifting chute.

[0008] Further, a positioning motor is fixedly installed on one side of the assembly plate. A positioning plate is fixedly sleeved on the output shaft of the positioning motor. The position of the positioning plate corresponds to the position of the limiting plate. The limiting plate is located between the height-adjusting electric push rod and the pre-tightening spring rod. A positioning groove adapted to the positioning plate is formed at the top of the hanging claw.

[0009] Further, a limiting slider is fixedly installed on the side of the connecting frame facing the vertical blunt cutter. The limiting slider is slidably installed on the vertical blunt cutter.

[0010] Further, first strengthening rods are fixedly installed on both sides of the vertical blunt cutter. Second strengthening rods are fixedly installed on both sides of the wedge-shaped transverse cutter. Both of the first strengthening rods are located inside the limiting slider.

[0011] Further, vertically arranged flaring plates are fixedly installed on both sides of the vertical blunt cutter. The two flaring plates are respectively fixedly connected to the two first strengthening rods.

[0012] Further, a sleeve skin is sleeved on the wedge-shaped scraper.

[0013] Further, a horizontally arranged stabilizing telescopic rod is fixedly installed on one side of the L-shaped transverse tool rest. The telescopic end of the stabilizing telescopic rod is fixedly installed on one side of the vertical blunt cutter.

[0014] A catalyst caking crushing device, including the catalyst caking crushing device using the crushing cutter head described in the present invention.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. By setting the wedge-shaped horizontal cutter and the vertical blunt cutter, the downward-moving wedge-shaped horizontal cutter cuts the catalyst on the side wall of the reactor, creating a vertical crushing cutter slot, allowing the upper vertical blunt cutter to insert into the slot and expand the slot from top to bottom as a whole, accelerating the crushing of the catalyst, and cutting a horizontal crushing cutter slot on the bottom-caked catalyst, so that the catalyst as a whole is divided into multiple small-volume catalyst fragments, greatly reducing the caking degree of the catalyst and reducing the loads on the cutter head, cutter seat, and output shaft of the drive motor during subsequent scraping of the catalyst.

[0017] 2. By setting three groups of drive cutter head assemblies, the three mutually staggered drive cutter head assemblies can, during a single cutting process, use the three vertical blunt cutters and the wedge-shaped horizontal cutter to cut three staggered cutter slots on the caked catalyst, not only deepening the crushing degree of the catalyst but also reducing the overall cutting time by adding three cutting directions in a single cut, accelerating the crushing of the catalyst.

[0018] 3. By setting the wedge-shaped scraper, after the caked catalyst is divided into multiple fragments, the electric push rod is adjusted to drive the wedge-shaped horizontal cutter to contract, and at the same time, the wedge-shaped scraper on the other side gradually approaches the inner wall of the reactor. Then, the electric push rod is adjusted to drive the wedge-shaped scraper to contact the inner walls of the side and bottom of the reactor at the same time. Finally, the drive motor drives the vertical blunt cutter and the wedge-shaped scraper on the other side to perform secondary crushing and scraping of the catalyst, further deepening the crushing degree of the catalyst.

[0019] 4. By setting the height-adjusting electric push rod, when the adjusting electric push rod and the height-adjusting electric push rod drive the wedge-shaped scraper to press on the inner wall of the reactor, the lifting hydraulic rod drives the cutter head to rise a certain distance as a whole, driving the wedge-shaped horizontal cutter to contract in two directions at the same time, so that the bottom of the wedge-shaped horizontal cutter also disengages from the catalyst and the inner wall of the reactor. Then, the wedge-shaped scraper contacts the inner wall of the reactor, preventing the wedge-shaped horizontal cutter from being worn when the drive motor drives the wedge-shaped scraper and the vertical blunt cutter to scrape the catalyst.

[0020] 5. By setting the pre-tightening spring rod, when the wedge-shaped scraper contacts the inner wall of the reactor, the pre-tightening spring rod contracts and applies a certain pre-tightening elastic force to the wedge-shaped scraper, giving the wedge-shaped scraper a certain amount of movement allowance. When the drive motor drives the three wedge-shaped scrapers to rotate, the wedge-shaped scraper can always press on the inner wall of the reactor under the action of centrifugal force and the pre-tightening elastic force of the pre-tightening spring rod, causing the catalyst fragments between the inner wall of the reactor and the wedge-shaped scraper to be gradually knocked off until the wedge-shaped scraper is in full contact with the inner wall of the reactor.

[0021] 6. The present invention is provided with a clamping motor, so that in the initial state, the skid-shaped scraper does not contact the inner wall of the reactor, and the pre-tightening spring rod remains stretched. At this time, the clamping plate on the output shaft of the clamping motor will be stuck in the clamping groove on one side of the limiting plate, and the pre-tightening spring rod is restricted by locking the assembly plate, the limiting plate and the suspension claw, so that the pre-tightening spring rod cannot continue to expand and contract, thereby avoiding affecting the movement process of the skid-shaped transverse cutter cutting the catalyst;

[0022] 7. The present invention is provided with a limiting slider, so that when the height-adjusting electric push rod drives the skid-shaped scraper to move up and down through the connecting frame and the scraper telescopic rod, the skid-shaped scraper slides up and down along the L-shaped transverse tool rest, and the limiting slider on one side of the connecting frame will slide up and down on one side of the vertical blunt cutter synchronously, so that the connecting frame and the L-shaped transverse tool rest play a role of guiding and stabilizing the movement process of the skid-shaped scraper from both sides respectively, and improving the connection strength of the overall frame of the L-shaped transverse tool rest, the skid-shaped scraper, the scraper telescopic rod, the height-adjusting electric push rod and the tool mounting base;

[0023] 8. The present invention is provided with a first reinforcing rod and a second reinforcing rod, so that the first reinforcing rod and the second reinforcing rod respectively fixedly assembled on both sides of the vertical blunt cutter and the skid-shaped transverse cutter can improve the overall structural strength of the vertical blunt cutter and the skid-shaped transverse cutter, and prevent the vertical blunt cutter and the skid-shaped transverse cutter from being damaged and broken when cutting the catalyst and when the vertical blunt cutter rotates to scrape the catalyst fragments;

[0024] 9. The present invention is provided with a sheath, so that the sheath sleeved on the skid-shaped scraper can contact the catalyst fragments and the inner wall of the reactor instead of the skid-shaped scraper itself, thereby avoiding wear of the skid-shaped scraper itself, and at the same time avoiding scratching the inner wall of the reactor when the skid-shaped scraper directly contacts the inner wall of the reactor, and only need to replace the sheath when the sheath is severely worn to continue to maintain the scraping function of the skid-shaped scraper.

[0038] As Figures 1 to 8 shown, a crushing cutter head and a catalyst caking crushing device using the cutter head include a lifting hydraulic rod 1. As Figure 1 shown, the telescopic end of the lifting hydraulic rod 1 is vertically downward and fixedly installed with a transmission box 2. As Figure 2 shown, a transmission motor 3 is fixedly installed inside the transmission box 2. The output shaft of the transmission motor 3 is downward and fixedly installed with a movable plate 4. The bottom of the movable plate 4 is fixedly installed with a suspension bracket 5. As Figure 3 shown, a three-pronged cutter holder 6 is fixedly installed at the bottom end of the suspension bracket 5. Drive cutter head assemblies are provided at the three ends of the three-pronged cutter holder 6, and the three drive cutter head assemblies are arranged in an interlaced manner;

[0039] The drive cutter head assembly is used to perform multi-position cutting on the caked catalyst along with the drive of the lifting hydraulic rod 1. As Figure 3 、 Figure 4 shown, the drive cutter head assembly includes a tool mounting base 7 fixedly sleeved on one end of the three-pronged cutter holder 6. One end of the tool mounting base 7 is fixedly installed with a vertical tool rest 8, and a vertical blunt cutting tool 9 is fixedly installed on the vertical tool rest 8. In this embodiment, the orientation of one drive cutter head assembly in the middle is opposite to that of the drive cutter head assemblies on both sides. The three vertical blunt cutting tools 9 are all located on an annular movement track with the axis position of the output shaft of the transmission motor 3 as the center of the circle. As Figure 5 shown, a horizontally arranged adjusting electric push rod 10 is fixedly installed at the bottom of the tool mounting base 7. The telescopic end of the adjusting electric push rod 10 faces away from the vertical blunt cutting tool 9 and is fixedly installed with an assembly plate 18. As Figure 7 shown, a horizontally arranged pre-tightening spring rod 19 is fixedly installed on one side of the assembly plate 18. The telescopic end of the pre-tightening spring rod 19 is fixedly installed with a limiting plate 20. A suspension claw 21 is fixedly installed on one side of the limiting plate 20. An L-shaped transverse cutter holder 11 is fixedly installed at the bottom of the suspension claw 21. As Figure 6 shown, a wedge-shaped transverse cutting tool 12 is fixedly installed at the bottom of the end of the L-shaped transverse cutter holder 11 facing the vertical blunt cutting tool 9. As Figure 5 shown, a height-adjusting electric push rod 13 is fixedly installed at the top of the tool mounting base 7. As Figure 8As shown in the figure, the telescopic end of the electric push rod 13 is adjusted to face vertically upward, and a connecting frame 14 is fixedly installed. On the side of the connecting frame 14 away from the vertical blunt cutter 9, a plurality of horizontally arranged scraper telescopic rods 15 are fixedly installed. The telescopic ends of the plurality of scraper telescopic rods 15 are fixedly installed with the same vertically arranged skid-shaped scraper 16. A lifting sliding groove 17 is formed on the side of the skid-shaped scraper 16 facing the vertical blunt cutter 9. As Figure 5As shown, the L-shaped horizontal tool rest 11 is slidably installed inside the lifting chute 17; specifically, when the crushing tool head is in use, the lifting hydraulic rod 1 drives the entire tool head to descend through the transmission box 2 and the suspension bracket 5. At this time, the front end of the wedge-shaped horizontal cutting tool 12 is aligned with the side of the vertical blunt cutting tool 9. When the bottom of the wedge-shaped horizontal cutting tool 12 contacts the caked catalyst inside the reactor, the descending wedge-shaped horizontal cutting tool 12 will cut through the surface of the caked and adhered catalyst on the side wall of the reactor, thus creating a vertical crushing knife slot, enabling the upper vertical blunt cutting tool 9 to insert into the knife slot and expand the knife slot from top to bottom as a whole, accelerating the crushing of the catalyst. When the wedge-shaped horizontal cutting tool 12 contacts the caked catalyst at the bottom of the reactor, the adjusting electric push rod 10 drives the wedge-shaped horizontal cutting tool 12 to cut back and forth on the top of the catalyst through the L-shaped horizontal tool rest 11, so that the wedge-shaped horizontal cutting tool 12 finally cuts out a horizontal crushing knife slot on the bottom caked catalyst. Then, the adjusting electric push rod 10 is driven to reset the wedge-shaped horizontal cutting tool 12, and the lifting hydraulic rod 1 drives the entire tool head to reset. At this time, the driving motor 3 in the transmission box 2 drives the movable plate 4 and the suspension bracket 5 to rotate, thereby driving the entire tool head to rotate by a certain angle. Then, the above operations are repeated, so that multiple knife slots distributed along the axis position of the output shaft of the driving motor 3 are cut on the caked catalyst on the side wall and bottom of the reactor, dividing the catalyst as a whole into multiple small-volume catalyst fragments, greatly reducing the degree of catalyst caking, and reducing the loads on the tool head, tool seat, and the output shaft of the driving motor 3 during subsequent scraping of the catalyst. By setting three groups of driving tool head assemblies, the three groups of driving tool head assemblies that intersect with each other can, during a single cutting process, use the three vertical blunt cutting tools 9 and the wedge-shaped horizontal cutting tool 12 to cut out three intersecting knife slots on the caked catalyst, not only deepening the crushing degree of the catalyst, but also reducing the overall cutting time by adding three cutting directions in a single cutting, accelerating the crushing of the catalyst. By setting the wedge-shaped scraper 16, after the caked catalyst is divided into multiple fragments, the adjusting electric push rod 10 at the bottom of the tool mounting base 7 drives the wedge-shaped horizontal cutting tool 12 to contract towards the axis position of the output shaft of the driving motor 3 through the L-shaped horizontal tool rest 11, and at the same time makes the wedge-shaped scraper 16 on the other side gradually approach the inner wall of the reactor. Then, the height-adjusting electric push rod 13 starts to contract, driving the wedge-shaped scraper 16 to slide down along the L-shaped horizontal tool rest 11 through the connecting frame 14 and the scraper telescopic rod 15, so that the wedge-shaped scraper 16 contacts the inner walls of the side and bottom of the reactor at the same time. Finally, the driving motor 3 drives the entire tool head to rotate rapidly, enabling the vertical blunt cutting tool 9 and the wedge-shaped scraper 16 on the other side to perform secondary crushing and scraping on the catalyst that has been preliminarily crushed inside the reactor, further deepening the crushing degree of the catalyst, making the catalyst detach from the inner wall of the reactor, and finally accumulating at the bottom for recovery. By setting the height-adjusting electric push rod 13, when the adjusting electric push rod 10 and the height-adjusting electric push rod 13 drive the wedge-shaped scraper 16 to press on the inner wall of the reactor, the lifting hydraulic rod 1 drives the entire tool head to rise by a certain distance, driving the wedge-shaped horizontal cutting tool 12 to contract simultaneously in two directions.The bottom of the skid-shaped cross cutter 12 is also separated from the catalyst and the inner wall of the reactor, and then the skid-shaped scraper 16 contacts the inner wall of the reactor, preventing the skid-shaped cross cutter 12 from being worn when the transmission motor 3 drives the skid-shaped scraper 16 and the vertical blunt cutter 9 to scrape the catalyst.

[0040] As Figure 7 shown, a clamping motor 22 is fixedly installed on one side of the assembly plate 18. A clamping plate 23 is fixedly sleeved on the output shaft of the clamping motor 22. The position of the clamping plate 23 corresponds to the position of the limiting plate 20. The limiting plate 20 is located between the height-adjusting electric push rod 13 and the pre-tightening spring rod 19. A clamping groove adapted to the clamping plate 23 is provided at the top of the hanging claw 21. Specifically, by setting the pre-tightening spring rod 19, when the skid-shaped scraper 16 contacts the inner wall of the reactor, the pre-tightening spring rod 19 contracts and applies a certain pre-tightening elastic force to the skid-shaped scraper 16, so that the skid-shaped scraper 16 has a certain margin of movement. When the transmission motor 3 drives the three groups of skid-shaped scrapers 16 to rotate, the skid-shaped scraper 16 can always press on the inner wall of the reactor under the action of centrifugal force and the pre-tightening elastic force of the pre-tightening spring rod 19, so that the catalyst fragments between the inner wall of the reactor and the skid-shaped scraper 16 are gradually knocked off until the skid-shaped scraper 16 is in full contact with the inner wall of the reactor. By setting the clamping motor 22, in the initial state, the skid-shaped scraper 16 does not contact the inner wall of the reactor, and the pre-tightening spring rod 19 remains stretched. At this time, the clamping plate 23 on the output shaft of the clamping motor 22 will be stuck in the clamping groove on one side of the limiting plate 20, and the pre-tightening spring rod 19 is restricted by locking the assembly plate 18, the limiting plate 20 and the hanging claw 21, so that the pre-tightening spring rod 19 cannot continue to expand and contract, thus avoiding affecting the movement process of the skid-shaped cross cutter 12 for cutting the catalyst.

[0041] As Figure 8 shown, a limiting slider 24 is fixedly installed on the side of the connecting frame 14 facing the vertical blunt cutter 9. As Figure 5 shown, the limiting slider 24 is slidably installed on the vertical blunt cutter 9. Specifically, by setting the limiting slider 24, when the height-adjusting electric push rod 13 drives the skid-shaped scraper 16 to move up and down through the connecting frame 14 and the scraper telescopic rod 15, the skid-shaped scraper 16 slides up and down along the L-shaped horizontal tool rest 11, and the limiting slider 24 on one side of the connecting frame 14 will slide up and down on one side of the vertical blunt cutter 9 synchronously, so that the connecting frame 14 and the L-shaped horizontal tool rest 11 can respectively play a guiding and stabilizing role in the up and down movement of the skid-shaped scraper 16 from the upper and lower sides, and improve the connection strength of the overall frame of the L-shaped horizontal tool rest 11, the skid-shaped scraper 16, the scraper telescopic rod 15, the height-adjusting electric push rod 13 and the tool mounting base 7.

[0042] As Figure 6As shown, first reinforcing rods 26 are fixedly installed on both sides of the vertical blunt cutting knife 9, and second reinforcing rods 27 are fixedly installed on both sides of the wedge-shaped horizontal cutting knife 12. Both of the two first reinforcing rods 26 are located inside the limit sliding block 24. In this embodiment, the first reinforcing rod 26 and the second reinforcing rod 27 are respectively installed on both sides of the "knife back" of the vertical blunt cutting knife 9 and the wedge-shaped horizontal cutting knife 12, away from the cutting edges of the vertical blunt cutting knife 9 and the wedge-shaped horizontal cutting knife 12. Specifically, by providing the first reinforcing rod 26 and the second reinforcing rod 27, the first reinforcing rod 26 and the second reinforcing rod 27 fixedly assembled on both sides of the vertical blunt cutting knife 9 and the wedge-shaped horizontal cutting knife 12 can improve the overall structural strength of the vertical blunt cutting knife 9 and the wedge-shaped horizontal cutting knife 12, preventing the vertical blunt cutting knife 9 and the wedge-shaped horizontal cutting knife 12 from being damaged and broken when cutting the catalyst and when the vertical blunt cutting knife 9 rotates to scrape the catalyst fragments.

[0043] As Figure 6 shown, flare plates 28 arranged vertically are fixedly installed on both sides of the vertical blunt cutting knife 9. The two flare plates 28 are respectively fixedly connected to the two first reinforcing rods 26. In this embodiment, the flare plates 28 are located between the first reinforcing rods 26 and the cutting edges of the vertical blunt cutting knife 9. The flare plates 28 are wedge-shaped, and the thickness of the bottom end is much smaller than that of the top end. Specifically, by providing the flare plates 28, when the vertical blunt cutting knife 9 descends and inserts into the pre-cut broken knife slot to expand the knife slot, the bottom ends of the flare plates 28 on both sides of the vertical blunt cutting knife 9 will also gradually insert into the knife slot to further expand the knife slot, further weakening the connection strength between the catalyst fragments and the adhesion force to the inner wall of the reactor.

[0044] As Figure 8 shown, a sheath 25 is sleeved on the wedge-shaped scraper 16. In this embodiment, threaded holes are provided on both sides of the wedge-shaped scraper 16, and the sheath 25 is fixedly sleeved on the wedge-shaped scraper 16 through fastening bolts. Specifically, by providing the sheath 25, the sheath 25 sleeved on the wedge-shaped scraper 16 can contact the catalyst fragments and the inner wall of the reactor instead of the wedge-shaped scraper 16 itself, thereby avoiding wear of the wedge-shaped scraper 16 itself and avoiding scratching the inner wall of the reactor when the wedge-shaped scraper 16 directly contacts the inner wall of the reactor. Moreover, only when the sheath 25 is severely worn, the sheath 25 needs to be replaced to continue maintaining the scraping function of the wedge-shaped scraper 16.

[0045] As Figure 6As shown, a horizontally arranged stable telescopic rod 29 is fixedly installed on one side of the L-shaped horizontal tool rest 11, and the telescopic end of the stable telescopic rod 29 is fixedly installed on one side of the vertical blunt cutter 9; specifically, by setting the stable telescopic rod 29, the stable telescopic rod 29 is fixedly assembled between the L-shaped horizontal tool rest 11 and the vertical blunt cutter 9, so that the L-shaped horizontal tool rest 11 is directly connected to the vertical blunt cutter 9, thereby improving the connection strength of the overall framework among the L-shaped horizontal tool rest 11, the suspension claw 21, the limit plate 20, the pre-tightening spring rod 19, the assembly plate 18, the adjusting electric push rod 10, the tool mounting base 7, the vertical tool rest 8, and the vertical blunt cutter 9.

[0046] A catalyst caking crushing device, including a catalyst caking crushing device using the crushing tool head of the present invention.

[0047] In summary: Preliminary crushing: The lifting hydraulic rod 1 drives the entire tool head to descend through the transmission box 2 and the suspension bracket 5. At this time, the front end of the skid-shaped horizontal cutter 12 is aligned with the side position of the vertical blunt cutter 9. When the bottom of the skid-shaped horizontal cutter 12 contacts the caked catalyst inside the reactor, the descending skid-shaped horizontal cutter 12 will cut through the surface of the caked catalyst adhered to and caked on the side wall of the reactor, thereby creating a vertical crushing slit, enabling the upper vertical blunt cutter 9 to insert into the slit and expand the slit from top to bottom as a whole, accelerating the crushing of the catalyst. When the skid-shaped horizontal cutter 12 contacts the caked catalyst at the bottom of the reactor, the adjusting electric push rod 10 drives the skid-shaped horizontal cutter 12 to cut back and forth on the top of the catalyst through the L-shaped horizontal tool rest 11, so that the skid-shaped horizontal cutter 12 finally cuts out a horizontal crushing slit on the caked catalyst at the bottom. Then, the adjusting electric push rod 10 drives the skid-shaped horizontal cutter 12 to reset, and the lifting hydraulic rod 1 drives the entire tool head to reset. At this time, the drive motor 3 in the transmission box 2 drives the movable plate 4 and the suspension bracket 5 to rotate, thereby driving the entire tool head to rotate a certain angle. Then, the above operations are repeated, so that multiple complex slits distributed along the axis of the output shaft of the drive motor 3 are cut on the caked catalyst on the side wall and bottom of the reactor, and the catalyst as a whole is divided into multiple small-volume catalyst fragments;

[0048] Secondary crushing: After the agglomerated catalyst is divided into a plurality of fragments, the positioning motor 22 drives the positioning plate 23 to disengage from the limiting plate 20 and the positioning groove, releasing the restriction on the pre-tightening spring rod 19. The adjusting electric push rod 10 at the bottom of the tool mounting base 7 drives the sled-shaped transverse cutting knife 12 to contract towards the axis position of the output shaft of the transmission motor 3 through the L-shaped transverse tool rest 11. At the same time, the sled-shaped scraping plate 16 on the other side gradually approaches the inner wall of the reactor. The lifting hydraulic rod 1 drives the entire tool head to rise a certain distance, driving the sled-shaped transverse cutting knife 12 to contract in two directions simultaneously, so that the bottom of the sled-shaped transverse cutting knife 12 also disengages from the catalyst and the inner wall of the reactor. Then the height-adjusting electric push rod 13 starts to contract, driving the sled-shaped scraping plate 16 to slide down along the L-shaped transverse tool rest 11 through the connecting frame 14 and the scraping plate telescopic rod 15, so that the sled-shaped scraping plate 16 contacts the inner walls of the side and bottom of the reactor at the same time. Finally, the transmission motor 3 drives the entire tool head to rotate rapidly, so that the vertical blunt cutting knife 9 and the sled-shaped scraping plate 16 on the other side perform secondary crushing and scraping on the catalyst that has been preliminarily crushed inside the reactor, further deepening the degree of crushing of the catalyst, causing the catalyst to disengage from the inner wall of the reactor, and finally accumulating at the bottom waiting to be recovered;

[0049] After crushing: The entire tool head resets to the initial state. The positioning motor 22 controls the positioning plate 23 to be stuck in the positioning groove on one side of the limiting plate 20, re-locking the pre-tightening spring rod 19. When the sleeve 25 is severely worn, the sleeve 25 is replaced to maintain the scraping function of the sled-shaped scraping plate 16.
