Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a high-strength, corrosion-resistant, refractory material screening device for ultra-large coal gas purification devices. Background Technology

[0002] In high-temperature industries such as metallurgy and chemical engineering, ultra-large gas purification devices are subjected to high-temperature (800-1200℃) and highly corrosive conditions for extended periods. Therefore, key components must be constructed using high-strength, corrosion-resistant refractory materials. The particle size uniformity of these materials directly affects their structural strength and corrosion resistance. Consequently, specialized screening devices are required to accurately classify the raw materials, making the stability and precision of these screening devices crucial.

[0003] Referring to the patent with announcement number CN215784935U, the disclosed multi-stage refractory material screening device solves the problems of inconvenient screen replacement and angle adjustment by using a clamping plate and a threaded structure, providing a reference for the optimization of similar equipment.

[0004] However, the device in this reference patent has a defect when used for screening refractory materials in ultra-large gas purification devices: it relies on threaded rods and threaded cylinders to fix the screen frame, but does not have a threaded rod limiting structure. Since this type of screening needs to process large-particle-size and high-hardness raw materials, the high-frequency vibration and impact force of the raw materials during the operation of the device will offset the static friction of the thread, causing the threaded rod to reverse and the threaded cylinder to shift, which in turn causes the first clamping plate to loosen and the screen to become loose, affecting the screening accuracy and even causing damage to the components, and cannot meet the long-term stable screening requirements. Utility Model Content

[0005] In view of the problem that the existing multi-stage screening device for refractory materials lacks a threaded rod limiting structure, when used for screening refractory materials in ultra-large gas purification devices (which need to process large-particle-size, high-hardness raw materials), the high-frequency vibration of the device and the impact force of the raw materials will offset the static friction of the threaded rod, causing the threaded rod to reverse, the threaded cylinder to shift, the first clamping plate to loosen, and the screen to become loose, thus affecting the screening accuracy and even causing damage to components, and failing to meet the long-term stable screening requirements, this utility model is proposed.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a high-strength, corrosion-resistant, refractory material screening device for an ultra-large coal gas purification device, including a base, a fixed plate symmetrically arranged above the base, a plurality of screens arranged between the fixed plates, and the screens connected to the fixed plates by a fixing mechanism, two support legs respectively arranged on opposite outer sides of the fixed plates, and the lower ends of the support legs connected to the base by a spring, and a vibration motor arranged on one side of the fixed plate;

[0007] The fixing mechanism includes a fixing seat and a clamping plate. The fixing seat and the clamping plate are symmetrically arranged between the fixing plates, and the clamping plate is located on the top of the fixing seat. The screen is arranged between the fixing seat and the clamping plate. The fixing seat has symmetrically connected screws inside, and one end of the screws extends to the outside of the fixing seat and is connected to a limit component. The fixing plate has an angle adjustment component connected to the fixing seat on the outer side.

[0008] As a preferred embodiment, the fixing mechanism further includes a locking block, which is symmetrically arranged at the bottom of the clamping plate. The top of the screen is provided with a locking groove that matches the locking block. The top of the fixing seat is symmetrically provided with a sliding groove. The screw is rotatably installed in the sliding groove. The outer wall of the screw is threaded with a slider. The top of the slider is hinged to the bottom of the clamping plate through a connecting rod.

[0009] As a preferred embodiment, the limiting assembly includes a housing, which is fixedly installed at one end of a fixed base. One end of a screw passes through the housing on one side. A ratchet is fitted inside the housing on the outer side of the screw, and a pawl engages on one side of the ratchet. A guide rod is rotatably installed on the inner wall of one side of the housing. A torsion spring is fitted on the outer side of the guide rod, and both ends of the torsion spring are fixedly connected to the guide rod and the housing, respectively. A sleeve is slidably fitted on the guide rod near the pawl end. One end of the pawl is fixedly fitted on the outer side of the sleeve. One end of the sleeve extends to the side of the housing away from the guide rod. A support plate is slidably fitted on the outer side of the sleeve, and the support plate is fixedly connected to the top of the housing. A baffle and a second spring are fitted on the outer side of the sleeve, and both the baffle and the second spring are located on the side of the support plate away from the pawl. Both ends of the second spring are fixedly connected to the inner wall of the housing and the baffle, respectively.

[0010] As a preferred embodiment, the guide rod consists of a columnar structure and two symmetrically arranged guide strips, and the end of the baffle away from the baffle is fixedly connected to the inner wall of the housing through a damper.

[0011] As a preferred embodiment, the angle adjustment assembly includes adjustment blocks symmetrically arranged on opposite outer walls of the fixed base. Two corresponding positions on the fixed plates are provided with adjustment slots adapted to the adjustment blocks. A fixed block is rotatably connected to one opposite outer end of each adjustment block. A second screw is rotatably connected to one side of each fixed block, with one end of the second screw penetrating the fixed block. A connecting block is threaded onto the outer wall of the second screw, and the connecting block is located on the side of the adjustment slot near the middle of the fixed plate. The connecting block is rotatably connected to the fixed plate, and the end of the fixed base away from the adjustment block is rotatably connected to the fixed plate.

[0012] As a preferred embodiment, the adjusting groove is arc-shaped, and the adjusting groove and the rotating connection between the fixed seat and the fixed plate are concentric.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] 1. This utility model combines a fixing mechanism with a limiting component. In the fixing mechanism, the screw on the outside of the rotating fixed seat drives the slider in the sliding groove to move, so that the two sliders move synchronously to the opposite inward side. Then, the connecting rod pushes the clamping plate to move up, causing the locking block to move out of the locking groove at the top of the screen to release the restriction and realize the convenient disassembly of the screen. Before disassembly, the limiting component needs to be operated, but it does not need to be operated when installing the screen. During disassembly, pulling the sleeve rod causes the pawl to be misaligned with the ratchet on the outside of the screw. At the same time, the sleeve rod drives the baffle to squeeze the spring and damper. Only after misalignment can the screw be rotated. The limiting component can restrict the screw to rotate only in the direction that drives the slider to move to the opposite outward side, avoiding the screw from loosening and reversing due to high-frequency vibration and raw material impact during the operation of the device. This effectively ensures the limiting and fixing effect of the screen and meets the long-term stable screening requirements of high-strength corrosion-resistant refractory materials for ultra-large gas purification devices.

[0015] 2. The angle adjustment component of this utility model has a torsion screw that can adjust the length of the screw between the connecting block and the fixed block. While rotating the screw, the adjusting block can slide up or down in the adjustment groove of the fixed plate. Since the adjustment groove and the rotating connection of the fixed seat and the fixed plate are concentric, the tilt angle of the screen can be adjusted synchronously during the sliding of the adjusting block. After adjusting to the appropriate position, the position of the adjusting block can be fixed by the cooperation of the length of the screw and the adjustment groove, adjusting block and other structures, so as to achieve precise adjustment of the angle of the fixed seat and the screen, adapt to the screening needs of high-strength corrosion-resistant refractory materials with different particle sizes and hardness, and improve the screening accuracy.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 - Figure 6 As shown, a high-strength, corrosion-resistant refractory material screening device for ultra-large gas purification equipment is provided. It includes a base 1, with symmetrically arranged fixed plates 3 above the base 1. Several screens 2 are arranged between the fixed plates 3, and the screens 2 are connected to the fixed plates 3 via a fixing mechanism. Two support legs 4 are respectively provided on the outer sides of the fixed plates 3, and the lower ends of the support legs 4 are connected to the base 1 via springs 5. A vibration motor 6 is provided on one side of the fixed plate 3. Through the cooperation of the support legs 4 and springs 5, the vibration transmitted to the base 1 during operation of the vibration motor 6 can be buffered, reducing the overall vibration loss of the device, while ensuring the efficient screening effect of the screens 2 driven by the vibration motor 6. This device is suitable for the screening requirements of high-strength, corrosion-resistant refractory materials for ultra-large gas purification equipment.

[0026] The fixing mechanism includes a fixing seat 7 and a clamping plate 8. The fixing seat 7 and the clamping plate 8 are symmetrically arranged between the fixing plate 3, and the clamping plate 8 is located on top of the fixing seat 7. The screen 2 is arranged between the fixing seat 7 and the clamping plate 8. The fixing seat 7 has symmetrically connected screws 10 inside, and one end of the screws 10 extends to the outside of the fixing seat 7 and is connected to a limiting component. The fixing plate 3 has an angle adjusting component connected to the fixing seat 7 on the opposite outer side. The symmetrical arrangement of the fixing seat 7 and the clamping plate 8 can form a stable clamp for the screen 2. The screws 10, together with the limiting component, can prevent loosening caused by vibration. The angle adjusting component can flexibly adjust the angle of the screen 2. The three work together to improve the fixing stability and screening adaptability of the device for the screen 2.

[0027] In this example, the fixing mechanism also includes a locking block 9, which is symmetrically arranged at the bottom of the clamping plate 8. The top of the screen 2 has a locking groove that matches the locking block 9. The top of the fixing base 7 has a sliding groove 11 symmetrically arranged. The screw 10 is rotatably installed in the sliding groove 11. The outer wall of the screw 10 is threadedly connected to a slider 12. The top of the slider 12 is hinged to the bottom of the clamping plate 8 through a connecting rod 13. The matching of the locking block 9 and the locking groove can enhance the limiting effect of the clamping plate 8 on the screen 2. The sliding groove 11 provides a stable sliding path for the slider 12. After the screw 10 drives the slider 12 to move, it drives the clamping plate 8 to rise and fall through the connecting rod 13, realizing the convenient assembly and disassembly of the screen 2.

[0028] In this example, the limiting component includes a housing 14, which is fixedly mounted on one end of a fixed base 7. One end of a screw 10 extends through the housing 14. A ratchet 15 is fitted inside the housing 14 on the outside of the screw 10. A pawl 19 is engaged on one side of the ratchet 15. A guide rod 16 is rotatably mounted on the inner wall of one side of the housing 14. In this example, the width of the pawl 19 is greater than the width of the ratchet 15. A torsion spring 18 is fitted on the outside of the guide rod 16, and both ends of the torsion spring 18 are fixedly connected to the guide rod 16 and the housing 14, respectively. A sleeve 17 is slidably fitted on the end of the guide rod 16 near the pawl 19. One end of the pawl 19 is fixedly fitted on the outside of the sleeve 17, and one end of the sleeve 17 extends into the housing 14. A support plate 20 is slidably fitted on the outer side of the sleeve rod 17 away from the guide rod 16, and the support plate 20 is fixedly connected to the top of the housing 14. A baffle 21 and a second spring 22 are fitted on the outer side of the sleeve rod 17, and both the baffle 21 and the second spring 22 are located on the side of the support plate 20 away from the pawl 19. The two ends of the second spring 22 are fixedly connected to the inner wall of the housing 14 and the baffle 21, respectively. The engagement of the ratchet 15 and the pawl 19 can limit the reverse rotation of the screw 10. The torsion spring 18 ensures that the pawl 19 and the ratchet 15 are stably engaged. The sleeve rod 17, the second spring 22 and the baffle 21 can flexibly disengage the pawl 19 to avoid the screw 10 from loosening due to high-frequency vibration of the device and ensure the fixing effect of the screen 2.

[0029] In this example, the guide rod 16 consists of a columnar structure and two symmetrically arranged guide bars. The end of the baffle 21 away from the baffle 21 is fixedly connected to the inner wall of the housing 14 through the damper 23. The columnar structure of the guide rod 16, in cooperation with the guide bars, can prevent the sleeve rod 17 from rotating, ensure the precise movement of the pawl 19, and enable the sleeve rod 17 and the guide rod 16 to rotate synchronously. The damper 23 can buffer the impact force when the sleeve rod 17 is pulled, reduce component wear, extend the service life of the limiting component, and also buffer the force of equipment vibration to prevent the pawl 19 from shaking significantly and affecting the limiting effect on the ratchet 15.

[0030] In this example, the angle adjustment component includes an adjustment block 25, which is symmetrically arranged on the opposite outer walls of the fixed base 7. Two fixed plates 3 have corresponding adjustment grooves 24 that fit the adjustment block 25. A fixed block 26 is rotatably connected to one of the opposite outer ends of the adjustment block 25. A screw 28 is rotatably connected to one side of the fixed block 26, with one end of the screw 28 penetrating through the fixed block 26. A connecting block 27 is threaded onto the outer wall of the screw 28, and the connecting block 27 is located on the side of the adjustment groove 24 near the middle of the fixed plate 3. The connecting block 27 is rotatably connected to the fixed plate 3, and the end of the fixed base 7 away from the adjustment block 25 is rotatably connected to the fixed plate 3. The fit between the adjustment block 25 and the adjustment groove 24 provides guidance for the angle adjustment of the fixed base 7. The screw 28, through its threaded engagement with the fixed block 26 and the connecting block 27, can precisely adjust its length, thereby driving the fixed base 7 to rotate around its rotating end, achieving flexible adjustment of the screen 2 angle to meet the screening requirements of refractory materials of different particle sizes.

[0031] In this example, the adjustment groove 24 is arc-shaped, and the adjustment groove 24 and the fixed seat 7 and the fixed plate 3 are at the same center. The arc-shaped adjustment groove 24 and the fixed seat 7 are aligned with the rotation center, which can ensure that the fixed seat 7 rotates smoothly when the adjustment block 25 slides, avoid the screen 2 from shifting during the angle adjustment process, improve the angle adjustment accuracy, and further ensure the screening effect.

[0032] During use, the device is initialized and the screen 2 is installed: First, place several screens 2 to be used on the top of the symmetrically arranged fixed base 7, ensuring that the position of the screen 2 is aligned with the clamping area of ​​the fixed base 7 and the clamping plate 8. Then, rotate the screw 10 inside the fixed base 7. When the screw 10 rotates in the slide groove 11, the slider 12 connected to its outer wall thread will move to the outer side along the slide groove 11. During the movement of the slider 12, the clamping plate 8 is pulled down by the connecting rod 13 at the top hinge until the locking block 9 at the bottom of the clamping plate 8 is locked into the locking groove at the top of the screen 2, completing the initial fixing of the screen 2. At this time, the pawl 19 in the limiting assembly is engaged with the ratchet 15 on the outside of the screw 10 under the elastic force of the torsion spring 18, restricting the screw 10 from rotating in the direction of driving the slider 12 to move inward, and avoiding the subsequent vibration that causes the screw 10 to loosen.

[0033] Screen 2 Angle Adjustment: Based on the particle size and hardness characteristics of the high-strength, erosion-resistant refractory material to be screened, the tilt angle of screen 2 is adjusted via the angle adjustment component. Specifically, twisting screw 28 causes it to rotate within the fixed block 26 and move axially, thereby changing the distance between connecting block 27 and fixed block 26. Since connecting block 27 is rotatably connected to fixed plate 3, and fixed block 26 is rotatably connected to adjusting block 25 on the outside of fixed seat 7, changes in the length of screw 28 will cause adjusting block 25 to move within the fixed plate 3. The sliding adjustment groove 24 inside the groove 24 is arc-shaped and concentric with the rotational connection of the fixed seat 7 and the fixed plate 3, ensuring the smooth sliding of the adjustment block 25. When the adjustment block 25 slides, the fixed seat 7 rotates around the rotational connection of the end away from the adjustment block 25 and the fixed plate 3, which simultaneously drives the top screen 2 to adjust the tilt angle until it reaches the angle suitable for screening the current material. Then, the screw 28 is stopped from being twisted. The thread self-locking characteristic of the screw 28, together with the adjustment block 25 and the adjustment groove 24, achieves the fixation of the screen 2 angle.

[0034] Screening Operation: Start the vibration motor 6 on one side of the fixed plate 3. The vibration energy generated by the vibration motor 6 is transmitted to the fixed plate 3, the fixed base 7, and the screen 2 to vibrate and screen the high-strength, corrosion-resistant refractory material to be screened. During this process, the spring 5 at the lower end of the outer support leg 4 of the fixed plate 3 will buffer the impact force transmitted to the base 1 by the vibration, reduce the overall vibration loss of the device, and ensure the vibration screening efficiency of the screen 2. The damper 23 in the limiting component can buffer the small displacement of the sleeve rod 17 caused by vibration. Together with the spring 22, it further ensures the stable engagement of the pawl 19 and the ratchet 15, always restricting the screw 10 from reversing, ensuring the stable fixed state of the screen 2, and avoiding the loosening of the screen 2 due to high-frequency vibration and the impact force of the raw materials.

[0035] Screen 2 disassembly and replacement: When screen 2 needs to be replaced, pull the sleeve 17 outward from the housing 14. The sleeve 17 slides along the guide rod 16, and at the same time drives the baffle 21 to squeeze the spring 22 and the damper 23. During the movement of the sleeve 17, the pawl 19 fixed on its outer side is misaligned with the ratchet 15, releasing the rotation restriction on the screw 10. Then rotate the screw 10 in the opposite direction to drive the slider 12 to move inward. Through the connecting rod 13, the clamp 8 is pushed upward, so that the locking block 9 is disengaged from the slot of the screen 2. The screen 2 can then be removed from the fixed seat 7 to complete the disassembly and replacement.
