Description

Technical Field

[0001] The invention relates to catalyst loading and unloading, and in particular to a crushing cutter head and a catalyst agglomeration crushing device using the cutter head. Background Art

[0002] During the unloading operation of the severely compacted catalyst in the reactor, the catalyst and other materials are often severely compacted and coked. At present, the crushing and unloading operation of the compacted catalyst crusher must be done manually with a pneumatic pick in a nitrogen environment, which consumes a lot of manpower, material resources and working hours. In addition, the safety of the operators cannot be well guaranteed in the harsh working environment, which has a serious impact on the construction progress and construction safety. Therefore, the current chemical industry often uses crushing devices to crush and remove the compacted catalyst.

[0003] The existing catalyst crushing device generally uses an air duct or a rotating crushing cutter head to crush the compacted materials in the reactor. When the material in the reactor is severely compacted, the air duct crushing speed is relatively slow and the construction time is long. The crushing method of the crushing cutter head is to directly make the rotating cutter head contact the compacted materials for crushing. When the inside of the reactor is severely compacted, the drive shaft of the crushing cutter head will bear a huge radial load, which may easily cause cracks at the connection between the cutter head and the drive shaft, or damage to the shaft seat of the drive shaft. Therefore, a crushing cutter head and a catalyst compaction crushing device using the cutter head are proposed. Summary of the invention

[0006] Furthermore, a positioning motor is fixedly installed on one side of the assembly plate, and 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 limit plate. The limit plate is located between the height-adjusting electric push rod and the preload spring rod, and a positioning groove that matches the positioning plate is opened on the top of the suspension claw.

[0007] Furthermore, a limiting slider is fixedly mounted on one side of the connecting frame facing the vertical blunt cutter, and the limiting slider is slidably mounted on the vertical blunt cutter.

[0008] Furthermore, first reinforcing rods are fixedly mounted on both sides of the vertical blunt cutter, and second reinforcing rods are fixedly mounted on both sides of the sled-shaped cross-cutting knife, and the two first reinforcing rods are both located inside the limiting sliding block.

[0009] Furthermore, vertically arranged expansion plates are fixedly installed on both sides of the vertical blunt cutter, and the two expansion plates are fixedly connected to the two first reinforcing rods respectively.

[0012] A catalyst agglomeration breaking device comprises a catalyst agglomeration breaking device using the breaking cutter head of the present invention.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention provides a sled-shaped cross-cutting knife and a vertical blunt cutting knife, so that the downwardly moving sled-shaped cross-cutting knife cuts the catalyst on the side wall of the reactor and cuts a vertical broken knife gap, so that the vertical blunt cutting knife above can be inserted into the knife gap to expand the knife gap from top to bottom as a whole, accelerate the breaking of the catalyst, and cut a horizontal broken knife gap on the catalyst that is compacted at the bottom, so that the catalyst as a whole is divided into a plurality of small-volume catalyst fragments, greatly reducing the degree of compaction of the catalyst, and reducing the load on the cutter head, the cutter seat and the output shaft of the transmission motor when scraping the catalyst later; 2. The present invention provides three sets of drive blade assemblies, so that the three sets of staggered drive blade assemblies can cut three staggered knife slits on the compacted catalyst by using three sets of vertical blunt cutters and sled-shaped cross-cutters in a single cutting process, which not only deepens the degree of catalyst crushing, but also reduces the overall cutting time by adding three cutting directions in a single cutting, thereby accelerating the catalyst crushing; 3. The present invention provides a skid-shaped scraper, so that after the compacted catalyst is divided into a plurality of fragments, the electric push rod is adjusted to drive the skid-shaped cross-cutting knife to shrink, and the skid-shaped scraper on the other side is gradually approached to the inner wall of the reactor, and then the electric push rod is raised to drive the skid-shaped scraper to contact the inner wall of the side and bottom of the reactor at the same time, and finally the transmission motor drives the vertical blunt cutter and the skid-shaped scraper on the other side to perform secondary crushing and scraping of the catalyst, thereby further deepening the degree of crushing of the catalyst; 4. The present invention is provided with a height-adjusting electric push rod, so that when the electric push rod is adjusted and the height-adjusting electric push rod drives the sled-shaped scraper to press against the inner wall of the reactor, the lifting hydraulic rod drives the cutter head to rise a certain distance as a whole, driving the sled-shaped cross-cutting knife to shrink in two directions at the same time, so that the bottom of the sled-shaped cross-cutting knife is also separated from the catalyst and the inner wall of the reactor, and then the sled-shaped scraper contacts the inner wall of the reactor, thereby preventing the sled-shaped cross-cutting knife from being worn when the transmission motor drives the sled-shaped scraper and the vertical blunt cutter to scrape the catalyst; 5. The present invention provides a preload spring rod, so that when the sled scraper contacts the inner wall of the reactor, the preload spring rod contracts and applies a certain preload elastic force to the sled scraper, so that the sled scraper has a certain margin of activity. When the transmission motor drives the three groups of sled scrapers to rotate, the sled scraper can always press against the inner wall of the reactor under the action of centrifugal force and the preload elastic force of the preload spring rod, so that the catalyst fragments between the inner wall of the reactor and the sled scraper are gradually knocked down until the sled scraper is completely in contact with the inner wall of the reactor; 6. The present invention sets a locking motor so that in the initial state, the sled-shaped scraper does not contact the inner wall of the reactor, and the pre-tightening spring rod remains stretched. At this time, the locking plate on the output shaft of the locking motor will be stuck in the locking 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 hanging claw, so that the pre-tightening spring rod cannot continue to extend and retract, thereby avoiding affecting the movement process of the sled-shaped cross-cutting knife cutting the catalyst; 7. The present invention provides a limit slider, so that when the height-adjusting electric push rod drives the sled-shaped scraper to move up and down through the connecting frame and the scraper telescopic rod, the sled-shaped scraper slides up and down along the L-shaped horizontal tool holder, and the limit slider on one side of the connecting frame will synchronously slide up and down on one side of the vertical blunt cutter, so that the connecting frame and the L-shaped horizontal tool holder respectively guide and stabilize the movement process of the sled-shaped scraper on both sides, thereby improving the connection strength of the L-shaped horizontal tool holder, the sled-shaped scraper, the scraper telescopic rod, the height-adjusting electric push rod and the overall frame of the tool mounting base; 8. The present invention provides a first reinforcing rod and a second reinforcing rod, so that the first reinforcing rod and the second reinforcing rod respectively fixedly mounted on both sides of the vertical blunt cutter and the sled-shaped cross-cutting knife can improve the overall structural strength of the vertical blunt cutter and the sled-shaped cross-cutting knife, and prevent the vertical blunt cutter and the sled-shaped cross-cutting knife from being damaged or broken when cutting the catalyst and when the vertical blunt cutter is rotating to scrape off catalyst fragments; 9. The present invention provides a sheath so that the sheath sleeved on the sled scraper can replace the sled scraper to contact the catalyst fragments and the inner wall of the reactor, thereby avoiding wear of the sled scraper itself and avoiding direct contact between the sled scraper and the inner wall of the reactor to scratch the inner wall of the reactor. The scraping function of the sled scraper can be maintained by replacing the sheath only when it is severely worn. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figures 1 to 8 As shown, a crushing cutter head and a catalyst plate crushing device using the cutter head include a lifting hydraulic rod 1, as shown in FIG. Figure 1As shown, the telescopic end of the lifting hydraulic rod 1 is vertically downward and fixedly installed with a transmission box 2, as shown in FIG. Figure 2 As shown, a transmission motor 3 is fixedly installed inside the transmission box 2, the output shaft of the transmission motor 3 faces downward and is fixedly installed with a movable plate 4, and a suspension frame 5 is fixedly installed at the bottom of the movable plate 4, as shown in FIG. Figure 3 As shown, a three-pronged knife holder 6 is fixedly mounted at the bottom end of the hanging frame 5, and three ends of the three-pronged knife holder 6 are provided with driving knife head assemblies, and the three driving knife head assemblies are arranged alternately with each other; The driving cutter head assembly is used to cut the compacted catalyst at multiple positions as the lifting hydraulic rod 1 is driven, such as Figure 3 , Figure 4 As shown, the drive cutter head assembly includes a cutter mounting base 7 fixedly sleeved on one end of the three-pronged cutter holder 6, a vertical cutter seat 8 is fixedly mounted on one end of the cutter mounting base 7, and a vertical blunt cutter 9 is fixedly mounted on the vertical cutter seat 8. In this embodiment, the direction of the drive cutter head assembly located in the middle is opposite to that of the drive cutter head assemblies located on both sides, and the three vertical blunt cutters 9 are all located on a circular motion trajectory with the axis position of the output shaft of the transmission motor 3 as the center, as shown in FIG. Figure 5 As shown, a horizontally arranged adjusting electric push rod 10 is fixedly installed at the bottom of the knife mounting base 7, and a mounting plate 18 is fixedly installed at the telescopic end of the adjusting electric push rod 10 away from the vertical blunt cutting knife 9. Figure 7 As shown, a horizontally arranged preload spring rod 19 is fixedly mounted on one side of the assembly plate 18, a limit plate 20 is fixedly mounted on the telescopic end of the preload spring rod 19, a suspension claw 21 is fixedly mounted on one side of the limit plate 20, and an L-shaped horizontal tool holder 11 is fixedly mounted on the bottom of the suspension claw 21, as shown in FIG. Figure 6 As shown, a sled-shaped cross-cutting knife 12 is fixedly installed at the bottom of the L-shaped transverse knife holder 11 facing the vertical blunt cutting knife 9. Figure 5 As shown, a height adjustment electric push rod 13 is fixedly installed on the top of the tool mounting base 7. Figure 8 As shown, the telescopic end of the height-adjusting electric push rod 13 is vertically upward and fixedly installed with a connecting frame 14, and a plurality of horizontally arranged scraper telescopic rods 15 are fixedly installed on the side of the connecting frame 14 away from the vertical blunt cutter 9, and the telescopic ends of the plurality of scraper telescopic rods 15 are fixedly installed with the same vertically arranged sled scraper 16, and the sled scraper 16 is provided with a lifting chute 17 on the side facing the vertical blunt cutter 9, as shown in FIG. Figure 5As shown, the L-shaped horizontal knife holder 11 is slidably installed inside the lifting slide 17; specifically, when the crushing knife head is in use, the lifting hydraulic rod 1 drives the knife head to descend as a whole through the transmission box 2 and the suspension frame 5. At this time, the front end of the sled-shaped cross-cutting knife 12 is consistent with the side position of the vertical blunt cutting knife 9. When the bottom of the sled-shaped cross-cutting knife 12 contacts the catalyst compacted inside the reactor, the downward-moving sled-shaped cross-cutting knife 12 will cut through the catalyst surface that is adhered and compacted on the side wall of the reactor, thereby cutting a vertical crushing knife gap, so that the vertical blunt cutting knife 9 above can be inserted into the knife gap to expand the knife gap from top to bottom as a whole, thereby accelerating the crushing of the catalyst. When the sled-shaped cross-cutting knife 12 contacts the catalyst compacted at the bottom of the reactor, the electric push rod 10 is adjusted to drive the L-shaped horizontal knife holder 11 to move the catalyst downward. The sled-shaped cross-cutting knife 12 cuts back and forth on the top of the catalyst, so that the sled-shaped cross-cutting knife 12 finally cuts a horizontal broken knife gap on the catalyst compacted at the bottom, and then the electric push rod 10 is adjusted to drive the sled-shaped cross-cutting knife 12 to reset, and the lifting hydraulic rod 1 drives the knife head to reset as a whole. At this time, the transmission motor 3 in the transmission box 2 drives the movable plate 4 and the suspension frame 5 to rotate, thereby driving the knife head to rotate as a whole by a certain angle, and then repeating the above operation, so that the catalyst compacted on the side wall and the bottom of the reactor is cut into a plurality of knife gaps distributed along the axis of the output shaft of the transmission motor 3, so that the catalyst as a whole is divided into a plurality of small-volume catalyst fragments, which greatly reduces the degree of catalyst compaction and reduces the load on the knife head, knife seat and the output shaft of the transmission motor 3 when the catalyst is subsequently scraped off. Three sets of drive blade assemblies are arranged, so that the three sets of staggered drive blade assemblies can use three sets of vertical blunt cutters 9 and sled-shaped cross-cutters 12 to cut three staggered knife slits on the compacted catalyst during a single cutting process, which not only deepens the degree of catalyst crushing, but also reduces the overall cutting time by adding three cutting directions in a single cutting, speeding up the catalyst crushing. By arranging the sled-shaped scraper 16, after the compacted catalyst is divided into a plurality of fragments, the adjusting electric push rod 10 at the bottom of the knife mounting base 7 drives the sled-shaped cross-cutter 12 to retract toward the axial position of the output shaft of the transmission motor 3 through the L-shaped horizontal knife holder 11, and at the same time makes the sled-shaped scraper 16 on the other side gradually approach the inner wall of the reactor, and then the electric push rod 13 is raised to start retracting, The sled scraper 16 is driven to slide down along the L-shaped horizontal knife holder 11 through the connecting frame 14 and the scraper telescopic rod 15, so that the sled scraper 16 contacts the inner wall of the side and bottom of the reactor at the same time. Finally, the transmission motor 3 drives the knife head to rotate rapidly as a whole, so that the vertical blunt cutter 9 and the sled scraper 16 on the other side perform secondary crushing and scraping on the catalyst that has been preliminarily crushed inside the reactor, further deepen the degree of crushing of the catalyst, make the catalyst separate from the inner wall of the reactor, and finally accumulate at the bottom waiting for recycling. By setting the height adjustment electric push rod 13, when the electric push rod 10 is adjusted and the height adjustment electric push rod 13 drives the sled scraper 16 to press on the inner wall of the reactor, the lifting hydraulic rod 1 drives the knife head to rise a certain distance as a whole, driving the sled cross-cutting knife 12 to shrink simultaneously in two directions.The bottom of the sled-shaped cross-cutting knife 12 is also separated from the catalyst and the inner wall of the reactor, and then the sled-shaped scraper 16 contacts the inner wall of the reactor to prevent the sled-shaped cross-cutting knife 12 from being worn when the transmission motor 3 drives the sled-shaped scraper 16 and the vertical blunt cutter 9 to scrape the catalyst.

[0020] like Figure 7 As shown, a positioning motor 22 is fixedly installed on one side of the assembly plate 18, and a positioning plate 23 is fixedly sleeved on the output shaft of the positioning motor 22. The position of the positioning plate 23 corresponds to the position of the limit plate 20. The limit plate 20 is located between the height-adjusting electric push rod 13 and the preload spring rod 19. The top of the suspension claw 21 is provided with a positioning groove adapted to the positioning plate 23. Specifically, by arranging the preload spring rod 19, when the sled-shaped scraper 16 contacts the inner wall of the reactor, the preload spring rod 19 contracts and applies a certain preload elastic force to the sled-shaped scraper 16, so that the sled-shaped scraper 16 has a certain margin of activity. When the transmission motor 3 drives the three groups of sled-shaped scrapers 16 to rotate, the sled-shaped scraper 16 can move under the influence of centrifugal force and the preload elastic force. The spring rod 19 is always pressed against the inner wall of the reactor under the action of the pre-tightening elastic force, so that the catalyst fragments between the inner wall of the reactor and the sled scraper 16 are gradually knocked down until the sled scraper 16 is completely in contact with the inner wall of the reactor. By setting the locking motor 22, in the initial state, the sled scraper 16 is not in contact with the inner wall of the reactor, and the pre-tightening spring rod 19 remains stretched. At this time, the locking plate 23 on the output shaft of the locking motor 22 will be stuck in the locking groove on one side of the limit plate 20. The pre-tightening spring rod 19 is restricted by locking the assembly plate 18, the limit plate 20 and the hanging claw 21, so that the pre-tightening spring rod 19 cannot continue to retract, thereby avoiding affecting the movement process of the sled cross-cutting knife 12 cutting the catalyst.

[0021] like Figure 8 As shown, the connecting frame 14 is fixedly mounted with a limiting slider 24 on one side facing the vertical blunt cutter 9. Figure 5 As shown, the limit slider 24 is slidably installed on the vertical blunt cutter 9; specifically, by setting the limit slider 24, when the height adjustment electric push rod 13 drives the sled scraper 16 to move up and down through the connecting frame 14 and the scraper telescopic rod 15, the sled scraper 16 slides up and down along the L-shaped horizontal tool holder 11, and the limit slider 24 on one side of the connecting frame 14 will synchronously slide up and down on one side of the vertical blunt cutter 9, so that the connecting frame 14 and the L-shaped horizontal tool holder 11 can guide and stabilize the up and down movement of the sled scraper 16 from the upper and lower sides respectively, thereby improving the connection strength of the overall frame of the L-shaped horizontal tool holder 11, the sled scraper 16, the scraper telescopic rod 15, the height adjustment electric push rod 13 and the tool mounting base 7.

[0022] like Figure 6As shown, first reinforcing rods 26 are fixedly installed on both sides of the vertical blunt cutter 9, and second reinforcing rods 27 are fixedly installed on both sides of the sled-shaped crosscutter 12. The two first reinforcing rods 26 are both located inside the limiting slider 24. In this embodiment, the first reinforcing rods 26 and the second reinforcing rods 27 are respectively installed on both sides of the "back of the knife" of the vertical blunt cutter 9 and the sled-shaped crosscutter 12, away from the blade positions of the vertical blunt cutter 9 and the sled-shaped crosscutter 12; specifically, by arranging the first reinforcing rods 26 and the second reinforcing rods 27, the first reinforcing rods 26 and the second reinforcing rods 27 fixedly installed on both sides of the vertical blunt cutter 9 and the sled-shaped crosscutter 12 can improve the overall structural strength of the vertical blunt cutter 9 and the sled-shaped crosscutter 12, and prevent the vertical blunt cutter 9 and the sled-shaped crosscutter 12 from being damaged or broken when cutting the catalyst and the vertical blunt cutter 9 rotates to scrape off catalyst fragments.

[0023] like Figure 6 As shown, both sides of the vertical blunt cutter 9 are fixedly installed with vertically arranged flaring plates 28, and the two flaring plates 28 are respectively fixedly connected to the two first reinforcing rods 26. In the present embodiment, the flaring plates 28 are located between the first reinforcing rods 26 and the blade of the vertical blunt cutter 9, and the flaring plates 28 are wedge-shaped, and the thickness of the bottom end thereof is much smaller than the thickness of the top end thereof. Specifically, by arranging the flaring plates 28, when the vertical blunt cutter 9 descends and is inserted into the pre-cut crushing knife gap and the knife gap is expanded, the bottom ends of the flaring plates 28 on both sides of the vertical blunt cutter 9 will also gradually be inserted into the knife gap, and the knife gap will be further expanded, thereby further weakening the connection strength between the catalyst fragments and the adhesion to the inner wall of the reactor.

[0024] like Figure 8 As shown, a sheath 25 is sleeved on the sled scraper 16. In this embodiment, threaded holes are provided on both sides of the sled scraper 16, and the sheath 25 is fixedly sleeved on the sled scraper 16 by fastening bolts. Specifically, by providing the sheath 25, the sheath 25 sleeved on the sled scraper 16 can replace the sled scraper 16 to contact the catalyst fragments and the inner wall of the reactor, thereby avoiding wear of the sled scraper 16 itself and avoiding direct contact between the sled scraper 16 and the inner wall of the reactor to scratch the inner wall of the reactor. In addition, the sheath 25 only needs to be replaced when it is severely worn to continue to maintain the scraping function of the sled scraper 16.

[0025] like Figure 6As shown, a horizontally arranged stabilizing telescopic rod 29 is fixedly installed on one side of the L-shaped transverse tool holder 11, and the telescopic end of the stabilizing telescopic rod 29 is fixedly installed on one side of the vertical blunt cutter 9; specifically, by setting the stabilizing telescopic rod 29, the stabilizing telescopic rod 29 is fixedly assembled between the L-shaped transverse tool holder 11 and the vertical blunt cutter 9, so that the L-shaped transverse tool holder 11 is directly connected to the vertical blunt cutter 9, thereby improving the connection strength of the overall frame between the L-shaped transverse tool holder 11, the hanging claw 21, the limit plate 20, the preload spring rod 19, the assembly plate 18, the adjusting electric push rod 10, the tool mounting base 7, the vertical tool holder 8 and the vertical blunt cutter 9.

[0026] A catalyst agglomeration breaking device comprises a catalyst agglomeration breaking device using the breaking cutter head of the present invention.

[0027] In summary: Initial crushing: The lifting hydraulic rod 1 drives the cutter head to descend as a whole through the transmission box 2 and the suspension frame 5. At this time, the front end of the sled-shaped cross-cutting knife 12 is consistent with the side position of the vertical blunt cutter 9. When the bottom of the sled-shaped cross-cutting knife 12 contacts the catalyst that is compacted inside the reactor, the downward-moving sled-shaped cross-cutting knife 12 will cut through the catalyst surface that is adhered and compacted on the side wall of the reactor, thereby cutting a vertical crushing knife gap, so that the vertical blunt cutter 9 above can be inserted into the knife gap to expand the knife gap from top to bottom as a whole, thereby accelerating the crushing of the catalyst. When the sled-shaped cross-cutting knife 12 contacts the catalyst that is compacted at the bottom of the reactor, the electric push rod 10 is adjusted to pass through the L-shaped cross-cutting knife 12. The sled-shaped cross-cutting knife 12 is driven toward the knife holder 11 to cut back and forth on the top of the catalyst, so that the sled-shaped cross-cutting knife 12 finally cuts a horizontal broken knife gap on the catalyst compacted at the bottom, and then the electric push rod 10 is adjusted to drive the sled-shaped cross-cutting knife 12 to reset, and the lifting hydraulic rod 1 drives the knife head to reset as a whole. At this time, the transmission motor 3 in the transmission box 2 drives the movable plate 4 and the suspension frame 5 to rotate, and then drives the knife head to rotate as a whole by a certain angle, and then repeats the above operation, so that the catalyst compacted on the side wall and the bottom of the reactor is cut into a plurality of knife gaps distributed along the axis of the output shaft of the transmission motor 3, so that the catalyst as a whole is divided into a plurality of small-volume catalyst fragments; Secondary crushing: After the compacted 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 preload spring rod 19, and the adjusting electric push rod 10 at the bottom of the knife mounting base 7 drives the sled-shaped cross-cutting knife 12 to retract toward the axial position of the output shaft of the transmission motor 3 through the L-shaped transverse knife holder 11, while making the sled-shaped scraper 16 on the other side gradually approach the inner wall of the reactor, and the lifting hydraulic rod 1 drives the knife head to rise a certain distance as a whole, driving the sled-shaped cross-cutting knife 12 to retract in two directions at the same time, so that the bottom of the sled-shaped cross-cutting knife 12 also The catalyst is separated from the inner wall of the reactor, and then the electric push rod 13 is raised to start to shrink, and the sled scraper 16 is driven to slide down along the L-shaped horizontal knife holder 11 through the connecting frame 14 and the scraper telescopic rod 15, so that the sled scraper 16 contacts the inner wall of the side and bottom of the reactor at the same time. Finally, the transmission motor 3 drives the knife head to rotate rapidly as a whole, so that the vertical blunt cutter 9 and the sled scraper 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, so that the catalyst is separated from the inner wall of the reactor, and finally piled up at the bottom waiting for recovery; After crushing: the cutter head is reset to the initial state as a whole, the locking motor 22 controls the locking plate 23 to be locked in the locking groove on one side of the limit plate 20, and the preload spring rod 19 is re-locked. When the sheath 25 is severely worn, the sheath 25 is replaced to maintain the scraping function of the sled scraper 16.
