Description

Technical Field

Background Technology

[0002] In the production process of denitrification catalysts (such as SCR denitrification catalysts), the formed catalyst blanks need to be cut into finished products of specific lengths or widths according to different operating conditions (such as the size of the denitrification reactor and the flue gas flow rate). The cutting accuracy directly affects the compatibility of the subsequent catalyst installation in the reactor and the denitrification efficiency.

[0003] Existing cutting mechanisms generally suffer from the following problems: 1. Low positioning accuracy: Conveyor belt feeding is often used. During the conveying process, the material is prone to deviation due to problems such as conveyor belt vibration, uneven distribution of catalyst weight, or lateral instability, resulting in a large cutting error. 2. Waste is difficult to clean: The fragments and dust generated during cutting are scattered and cleaning is time-consuming, affecting production efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 The present invention provides the following technical solution: a cutting mechanism for processing denitrification catalyst, including a cutting platform 1 and a positioning component, a surface pressure fixing component 4, and a cutting component 5 integrated into the cutting platform 1, and also includes a filter recovery component 6 disposed below the cutting platform 1.

[0022] Furthermore, by Figure 1As shown, in this embodiment, the cutting platform 1 has a cutting hole 11 extending through its upper and lower surfaces for the cutting component of the cutting assembly 5 to pass through and for waste to fall. The positioning assembly is used to transport the denitrification catalyst along a preset direction to the cutting station above the cutting hole 11. The surface pressure fixing assembly 4 is set above the cutting station and is used to apply vertical pressure to the denitrification catalyst at the cutting station to achieve fixation. The cutting assembly 5 is set above the cutting station and located on one side of the surface pressure fixing assembly 4, and is used to drive the cutting component to move along the vertical direction to complete the catalyst cutting. The filtration and recovery assembly 6 is used to receive the waste falling from the cutting hole 11 and to perform vibration screening and classification recycling of the waste. With the above scheme, when in use, the operator places the denitrification catalyst to be cut (usually a honeycomb or plate structure) at the feed end of the positioning assembly, and the positioning assembly transports the denitrification catalyst along a preset direction to the cutting station above the cutting hole 11.

[0023] After the denitrification catalyst is in place, the surface pressure fixing component 4 is activated to apply uniform vertical pressure to the catalyst at the cutting station, thereby achieving stable fixing of the catalyst and preventing the catalyst from shifting or breaking due to vibration during the cutting process.

[0024] After the surface pressure fixing component 4 is fixed, the cutting component 5 is started, driving the cutting component to move in the vertical direction to complete the catalyst cutting.

[0025] The waste generated during cutting (including chips and scraps) falls naturally through the cutting hole 11 into the filter and recycling assembly 6 below. The filter and recycling assembly 6 is used to receive the waste falling from the cutting hole 11 and to perform vibration screening and sorting recycling of the waste.

[0026] Optionally, by Figure 1 and Figure 2 As shown in this embodiment, the positioning component includes a vertical storage bin 2 and a pushing component 3. The vertical storage bin 2 is fixed on the top surface of the cutting platform 1 near the surface pressure fixing component 4. It has a receiving cavity for stacking denitrification catalysts. The bottom of the vertical storage bin 2 is provided with a discharge channel 21 that communicates with the upper surface of the cutting platform 1, and the width of the discharge channel 21 is adapted to the width of the denitrification catalyst. The pushing component 3 is set on the cutting platform 1 and is used to push the denitrification catalyst output from the discharge channel 21 along the upper surface of the cutting platform 1 to the cutting station. With the above scheme, when in use, the operator first vertically stacks the denitrification catalyst (plate-shaped / honeycomb-shaped) to be cut along the receiving cavity of the vertical storage bin 2. The height of the receiving cavity is designed to be 5-8 layers of catalyst stacking height.

[0027] In the initial state, the discharge channel 21 at the bottom of the vertical storage bin 2 is normally open. Due to the gravity generated by the stacking of catalysts, the bottom layer of catalyst will naturally fall to the upper surface of the cutting platform 1. The width of the discharge channel 21 (which is adapted to the width of the catalyst) restricts the lateral displacement of the catalyst, ensuring that the axis of the falling catalyst is consistent with the subsequent pushing direction.

[0028] Start the push component 3. The push component 3 will push the denitrification catalyst output from the discharge channel 21 along the upper surface of the cutting platform 1 to the cutting station.

[0029] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the pushing component 3 includes an inverted L-shaped pushing plate 31 and a driving mechanism 32. An angled brace 311 is fixed between the horizontal and vertical portions of the inverted L-shaped pushing plate 31. The driving mechanism 32 includes a guide slider 321, a moving plate 322, a fixed plate 323, a threaded screw 324, a servo motor 325, and two guide rods 326. The bottom end of the vertical portion of the inverted L-shaped pushing plate 31 is attached to the top surface of the cutting platform 1. A guide sliding hole 12 extending along the catalyst pushing direction is provided on the cutting platform 1. The guide slider 321 is fixed to the bottom end of the inverted L-shaped pushing plate 31 and slides in cooperation with the guide sliding hole 12. The moving plate 322 is fixed to the bottom end of the guide slider 321. Two fixed plates 323 are fixed at intervals to the bottom surface of the cutting platform 1. The threaded screw 324 is rotatably mounted between the two fixed plates 323. The threaded screw 324 is threaded together; the servo motor 325 is fixed to the outer wall of the threaded screw 324 to drive the threaded screw 324 to rotate; two guide rods 326 are symmetrically fixed between the two threaded screws 324 and pass through the moving plate 322. With the above scheme, when in use, the servo motor 325 is started, and the servo motor 325 drives the threaded screw 324 to rotate in a directional manner between the two fixed plates 323 through the coupling (pushing when rotating forward and resetting when rotating backward). Since the moving plate 322 and the threaded screw 324 are threaded together, the rotational motion of the threaded screw 324 is converted into the linear motion of the moving plate 322 along the axial direction. The two symmetrically distributed guide rods 326 pass through the guide holes of the moving plate 322, restricting the moving plate 322 to rotate synchronously with the threaded screw 324, ensuring that it moves smoothly only along the axial direction of the guide rods 326.

[0030] The linear motion of the moving plate 322 is transmitted to the inverted L-shaped push plate 31 through the rigidly connected guide slider 321. The front end of the vertical part of the inverted L-shaped push plate 31 contacts the catalyst and pushes the catalyst out of the discharge channel 21 as it moves. At this time, the horizontal part of the inverted L-shaped push plate 31 supports the catalyst on the upper side, preventing the catalyst from falling and causing motion interference to the return stroke of the inverted L-shaped push plate 31.

[0031] After the cutting is completed, the servo motor 325 drives the threaded screw 324 to rotate in the opposite direction, causing the moving plate 322, the guide slider 321 and the reverse L-shaped push plate 31 to retract along the original path. When the reverse L-shaped push plate 31 retracts to the outside of the discharge channel 21, the catalyst will naturally fall to the upper surface of the cutting platform 1, waiting to be pushed again.

[0032] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the surface pressure fixing assembly 4 includes a first side plate 41, a first top plate 42, a pressure plate 43, a first cylinder 44, a first guide post 45, and a rubber pad 46. The two first side plates 41 are symmetrically fixed to the top surface of the cutting platform 1. The first top plate 42 is fixed to the top of the first side plate 41. The first cylinder 44 is fixed to the top surface of the first top plate 42, and the piston rod of the first cylinder 44 passes through the first top plate 42 and is fixedly connected to the pressure plate 43. The two first guide posts 45 are symmetrically fixed to the top surface of the pressure plate 43 and pass through the first top plate 42. The rubber pad 46 is bonded and fixed to the bottom surface of the pressure plate 43. With the above scheme, when the pushing assembly 3 accurately delivers the denitrification catalyst to the cutting station, the first cylinder 44 is started. The first cylinder 44 receives compressed air through the air pipe. Under the action of the air pressure difference, the piston in the cylinder drives the piston rod to extend downward, directly transmitting the power to the pressure plate 43, driving the pressure plate 43 to move vertically towards the cutting station.

[0033] During the descent of the pressure plate 43, the two first guide columns 45 are moved downward simultaneously, which can effectively limit the lateral displacement of the pressure plate 43 and ensure that it moves only in the vertical direction.

[0034] When the rubber pad 46 on the bottom of the pressure plate 43 approaches the catalyst surface, the first cylinder 44 continues to apply pressure to achieve flexible contact and avoid rigid compression that could cause the catalyst (especially honeycomb catalyst) to break at the edges and corners through elastic buffering.

[0035] Optionally, by Figure 1 and Figure 4As shown, in this embodiment, the cutting assembly 5 includes a second side plate 51, a second top plate 52, an n-shaped blade holder 53, a cutting blade 54, a second cylinder 55, second guide posts 56, locking bolts 57, and locking nuts 58; the two second side plates 51 are symmetrically fixed to the top surface of the cutting platform 1; the second top plate 52 is fixed to the top of the second side plates 51; the second cylinder 55 is fixed to the top surface of the second top plate 52, and the piston rod of the second cylinder 55 passes through the second top plate 52 and is fixedly connected to the n-shaped blade holder 53; the cutting blade 54 is detachably installed on the n-shaped blade holder 53; the two second guide posts 56... Symmetrically fixed to the top surface of the n-type blade holder 53 and penetrating the second top plate 52; multiple locking bolts 57 are evenly distributed and penetrate the n-type blade holder 53 and the cutting blade 54; locking nuts 58 are installed on the protruding end of the locking bolts 57 by thread engagement. With the above scheme, when the surface pressure fixing component 4 completes the stable pressure fixing of the catalyst, the second cylinder 55 is started. The second cylinder 55 drives the piston downward through compressed air, which transmits power to the n-type blade holder 53, driving the blade holder and the cutting blade 54 below to move vertically towards the cutting station, starting the cutting process.

[0036] During the descent of the n-type tool holder 53, the two second guide columns 56 are moved downward simultaneously, which can effectively limit the lateral displacement of the n-type tool holder 53 and ensure that it moves only in the vertical direction.

[0037] The cutting blade 54 is secured by multiple spaced locking bolts 57 and locking nuts 58, which ensures the stable installation of the cutting blade 54 and facilitates the disassembly and replacement of severely worn cutting blades 54.

[0038] During the cutting process, the cutting blade 54 continues to descend into the cutting hole 11 after passing through the catalyst (beyond the thickness of the catalyst) to ensure a complete cut.

[0039] Optionally, by Figure 1 , Figure 5 and Figure 6As shown, in this embodiment, the filtration and recycling assembly 6 includes a vibration box 61, a U-shaped partition 62, a filter drawer 63, a fine material recycling drawer 64, a vibration motor 65, a flexible mounting mechanism 66, and a locking mechanism 67. The flexible mounting mechanism 66 includes a mounting block 661, a mounting rod 662, a limiting plate 663, and a balance spring 664. The vibration box 61 is located directly below the cutting platform 1, and the top opening of the vibration box 61 corresponds to the cutting hole 11. The U-shaped partition 62 is fixed inside the vibration box 61, dividing the interior of the vibration box 61 into upper and lower chambers, and the middle of the U-shaped partition 62 forms a channel for waste material to fall. The filter drawer 63 is slidably disposed in the upper chamber of the vibration box 61, and the bottom plate of the filter drawer 63 has multiple evenly distributed filter holes 631. The fine material recycling drawer 64 is slidably disposed in the lower chamber of the vibration box 61 to receive fine material falling from the filter holes 631. The vibrating motor 65 is fixed to the bottom of the vibrating box 61 to drive the vibrating box 61 to vibrate up and down; the mounting block 661 is fixed to the outer wall of the vibrating box 61; the mounting rod 662 is fixed to the bottom of the cutting platform 1 and passes through the mounting block 661, and the limiting plate 663 is fixed to the bottom end of the mounting rod 662; there are balance springs 664 sleeved on the mounting rod 662 between the limiting plate 663 and the mounting block 661 and between the mounting block 661 and the cutting platform 1; the locking mechanism 67 is used to lock the filter drawer 63 and the fine material recovery drawer 64 in the working state. After adopting the above scheme, when in use, the denitrification catalyst waste (including block scraps and powder debris) generated during the cutting process falls freely through the cutting hole 11 of the cutting platform 1 and directly enters the top opening of the vibrating box 61 directly below. The opening size of the vibrating box 61 (larger than the edge of the cutting hole 11) ensures that no waste is missed.

[0040] When the waste material enters the filter drawer 63, the vibration motor 65 (a three-phase asynchronous vibration motor with a rated speed of 2800 r / min and a vibration force of 5-8 kN) is started. The centrifugal vibration force generated by the vibration motor 65 drives the vibration box 61 to perform high-frequency vertical oscillation (amplitude 3-5 mm, frequency 50 Hz). The filter drawer 63 oscillates synchronously with the vibration box 61. The filter holes 631 on its bottom plate (the hole diameter is designed according to the particle size of the catalyst waste) classify and screen the waste material: the blocky scraps (coarse material) with a particle size larger than the filter holes 631 are concentrated in the filter drawer 63; the powder and debris (fine material) with a particle size smaller than the filter holes 631 fall through the filter holes 631 and enter the fine material recovery drawer 64 in the lower chamber through the channel in the middle of the U-shaped partition 62, realizing the automatic separation of coarse and fine waste.

[0041] During the vibration of the vibrating box 61, the flexible mounting mechanism 66 ensures vibration stability through multiple elastic constraints: the mounting block 661 moves synchronously with the vibrating box 61, and the balance springs 664 (made of 65Mn spring steel with an elastic coefficient of 800N / mm) on the upper and lower sides of the mounting rod 662 respectively bear the tension and compression. The upper balance spring 664 buffers the impact force of the vibrating box 61 moving upward, and the lower balance spring 664 counteracts the inertial force of the downward movement. The two work together to make the vibrating box 61 move vertically only along the axis of the mounting rod 662, avoiding the decrease in waste screening efficiency due to vibration deviation.

[0042] Optionally, by Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the locking mechanism 67 includes a locking plate 671, a fixing block 672, a positioning screw 673, and a wing nut 674. The locking plate 671 is fixed to the front of both the filter drawer 63 and the fine material recovery drawer 64, and a notch 6711 is provided on the locking plate 671. The fixing block 672 is fixed to the outer wall of the vibration box 61, and the positioning screw 673 is fixed to the fixing block 672 and passes through the notch 6711. The wing nut 674 is installed on the protruding end of the positioning screw 673 by threaded engagement. With the above scheme, during use, when the filter drawer 63 or the fine material recovery drawer 64 is pushed into the corresponding chamber of the vibration box 61, the locking plate 671 on the front of the drawer moves synchronously with the drawer until the drawer is fully pushed in. At this time, the positioning screw 673 on the fixing block 672 passes through the notch 6711.

[0043] After the drawer is in place, the operator manually tightens the wing nut 674 at the protruding end of the positioning screw 673. The wing nut 674 moves axially along the positioning screw 673 and gradually presses against the locking plate 671, thus reinforcing the filter drawer 63 and the fine material recovery drawer 64.

[0044] When it is necessary to clean the waste material in the drawer, the operator unscrews the wing nut 674 in the opposite direction. At this time, the positioning screw 673 releases the axial constraint on the locking plate 671, and the operator can directly pull out the filter drawer 63 and the fine material recovery drawer 64.

[0045] It should be noted that the servo motor 325, the first cylinder 44, the second cylinder 55, and the vibration motor 65 are all commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0046] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0047] Components not described in detail in this article are existing technologies.

[0048] The working principle and usage process of this utility model: When in use, the cutting device of this utility model is controlled by a PLC control system, and the position of the catalyst reaching the cutting station is located by a photoelectric sensor. The operator vertically stacks the denitrification catalyst (plate-shaped or honeycomb-shaped) to be cut along the receiving cavity of the vertical storage bin 2. During processing, the servo motor 325 is started, driving the threaded screw 324 to rotate. Through the moving plate 322 and the guide slider 321, the inverted L-shaped push plate 31 moves along the guide sliding hole 12. The guide rod 326 restricts the rotation of the moving plate 322 to ensure the linear movement of the inverted L-shaped push plate 31. The front end of the vertical part of the inverted L-shaped pusher plate 31 contacts the catalyst and pushes the catalyst out of the discharge channel 21 as it moves. At this time, the horizontal part of the inverted L-shaped pusher plate 31 supports the catalyst on the upper side, preventing the catalyst from falling and causing motion interference to the return of the inverted L-shaped pusher plate 31. After the cutting is completed, the servo motor 325 drives the threaded screw 324 to rotate in the opposite direction, causing the moving plate 322, the guide slider 321 and the reverse L-shaped push plate 31 to retract along the original path. When the reverse L-shaped push plate 31 retracts to the outside of the discharge channel 21, the catalyst will naturally fall to the upper surface of the cutting platform 1, waiting to be pushed again. When the push component 3 accurately delivers the denitrification catalyst to the cutting station, the first cylinder 44 is started. The first cylinder 44 receives compressed air through the air pipe. Under the action of the air pressure difference, the piston in the cylinder drives the piston rod to extend downward, directly transmitting the power to the pressure plate 43, driving the pressure plate 43 to move vertically towards the cutting station. During the descent of the pressure plate 43, the two first guide columns 45 are moved downward simultaneously, which can effectively limit the lateral displacement of the pressure plate 43 and ensure that it moves only in the vertical direction. When the rubber pad 46 on the bottom surface of the pressure plate 43 approaches the catalyst surface, the first cylinder 44 continues to apply pressure to achieve flexible contact and avoid rigid compression that could cause the catalyst (especially honeycomb catalyst) to break at the edges and corners through elastic buffering. After the surface pressure fixing component 4 completes the stable pressure fixing of the catalyst, the second cylinder 55 is started. The second cylinder 55 drives the piston downward through compressed air, which transmits power to the n-type blade holder 53, driving the blade holder and the cutting blade 54 below to move vertically towards the cutting station and start the cutting process. During the descent of the n-type tool holder 53, the two second guide columns 56 are moved downward simultaneously, which can effectively limit the lateral displacement of the n-type tool holder 53 and ensure that it moves only in the vertical direction. During the cutting process, the cutting blade 54 continues to descend into the cutting hole 11 after passing through the catalyst (beyond the thickness of the catalyst) to ensure a complete cut; The denitrification catalyst waste (including block scraps and powder debris) generated during the cutting process falls freely through the cutting hole 11 of the cutting platform 1 and directly enters the top opening of the vibration box 61 directly below. The opening size of the vibration box 61 (larger than the edge of the cutting hole 11) ensures that no waste is missed. When the waste material enters the filter drawer 63, the vibration motor 65 is started. The centrifugal excitation force generated by the vibration motor 65 drives the vibration box 61 to perform high-frequency vertical oscillation. The filter drawer 63 oscillates synchronously with the vibration box 61. The filter holes 631 on its bottom plate classify and screen the waste material: the blocky scraps (coarse material) with a particle size larger than the filter holes 631 are concentrated and piled up in the filter drawer 63; the powder and debris (fine material) with a particle size smaller than the filter holes 631 fall through the filter holes 631 and enter the fine material recovery drawer 64 in the lower chamber through the channel in the middle of the U-shaped partition 62, realizing the automatic separation of coarse and fine waste.
