Description

Technical Field

[0001] This utility model relates to the field of catalyst technology, and in particular to a catalyst end-face dust collection device. Background Technology

[0002] In fields such as chemical catalysis, environmental governance, and energy conversion, catalysts are the core medium ensuring efficient reactions. The cleanliness of their end faces directly determines the exposure level of catalytic active sites, reaction mass transfer efficiency, and overall service life. During the production, molding, storage, transportation, and post-reaction regeneration processes, dust, reaction residues, particulate impurities, and other contaminants easily adhere to the end faces of catalysts. If these contaminants are not removed in time, they will clog the micropores and active sites on the catalyst surface, leading to a significant decrease in catalytic efficiency and even affecting product purity and reaction stability. Therefore, end-face dust removal and cleaning has become a key process in catalyst production quality inspection, pre-use pretreatment, and regeneration maintenance.

[0003] In existing catalyst end-face dust collection solutions, to reduce equipment procurement and maintenance costs, the industry generally adopts a single dust collection device and manual rotation operation mode. In this mode, after cleaning one end of the catalyst with a fixed dust collection mechanism, the operator needs to manually or with the help of simple tools rotate the catalyst so that the uncleaned end is aligned with the dust collection device for a second dust collection operation.

[0004] However, this method also has the following drawbacks: most catalysts are inherently fragile and have low mechanical strength. During manual rotation, they are prone to end-face damage, structural cracking, or even direct catalyst failure due to collisions, squeezing, or uneven stress, which increases production costs. At the same time, the alignment accuracy of manual rotation is unstable, which can lead to poor contact between the dust collection device and the catalyst end face. This not only affects the cleaning effect but may also cause dust diffusion and pollute the working environment. Therefore, we propose a catalyst end-face dust collection device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a catalyst end-face dust collection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a catalyst end face dust collection device, including a dust collection platform, a guide ring fixedly installed on the top of the dust collection platform, a catalyst placement platform fixedly installed on the top of the dust collection platform corresponding to the guide ring, a positioning plate slidably installed on the top of the guide ring, a dust collection device fixedly installed on the top of the positioning plate, an integrated dust collection head fixedly installed on one side of the dust collection device, a fixed base fixedly installed on the top of the dust collection platform, two limiting discs fixedly sleeved on the outer wall of the fixed base, and a positioning component provided on the outer wall of the fixed base.

[0007] Preferably, the bottom of the positioning plate is fixed with an arc-shaped sliding strip, the guide ring is circular and the top of the guide ring is provided with a sliding groove, and the sliding strip is slidably connected in the sliding groove.

[0008] Preferably, an adjustment plate is fixedly installed on the bottom of the positioning plate corresponding to the outer side of the sliding bar, and an adjustment handle is fixedly installed on the outer side of the adjustment plate.

[0009] Preferably, two guide plates are fixedly provided on the inner side of the adjusting plate. Both ends of the two guide plates are arc-shaped, and a V-shaped groove is opened on the side of the two guide plates that are close to each other, corresponding to the middle position.

[0010] Preferably, there are two fixing seats, which are arranged symmetrically.

[0011] Preferably, the positioning component includes an arched member, an L-shaped bar, a pressing disc, and a force-bearing spring. Two arched members are slidably sleeved between the two limiting discs. The two arched members are V-shaped and symmetrically arranged. Two pressing discs are slidably sleeved between the two arched members on the outer wall of the fixing seat. The two pressing discs are respectively fixed to the two arched members by two L-shaped bars. A force-bearing spring is sleeved between the two pressing discs on the outer wall of the fixing seat.

[0012] The beneficial effects of this utility model are: 1. In use, the positioning plate rotates smoothly along the sliding groove of the guide ring via the bottom sliding strip, driving the dust collection device to rotate 180 degrees around the catalyst placement platform. Combined with the engagement and positioning of the arched component in the positioning assembly with the V-shaped groove on the guide plate, the dust collection head can be quickly switched and accurately aligned at both ends of the catalyst without moving the catalyst itself. This solves the problem of damage and cracking easily caused by traditional manual catalyst handling, and avoids increased costs due to catalyst failure. Simultaneously, the mechanical rotation and automatic centering of the V-shaped groove ensure stable contact between the dust collection head and the catalyst end face, overcoming the shortcomings of inaccurate alignment and poor cleaning effect caused by manual handling.

[0013] 2. When using this utility model, the arched part is pushed towards the center, which drives the extrusion plate to squeeze the force spring to unlock; after rotating to the position, the rebound force of the force spring pushes the arched part into the V-shaped groove to complete the locking. The limiting plate restricts the stroke of the extrusion plate to avoid excessive compression of the spring. The elastic locking structure ensures that the positioning plate is stable and does not loosen after rotation, ensuring that the dust suction head and the end face are tightly attached during the dust suction process, preventing dust from spreading and polluting the environment.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-4 As shown, a catalyst end face dust collection device is disclosed, including a dust collection platform 1, a guide ring 2 fixedly installed on the top of the dust collection platform 1, a catalyst placement platform 3 fixedly installed on the top of the dust collection platform 1 corresponding to the guide ring 2, a positioning plate 4 slidably installed on the top of the guide ring 2, a dust collection device 5 fixedly installed on the top of the positioning plate 4, an integrated dust collection head 6 fixedly installed on one side of the dust collection device 5, a fixing seat 11 fixedly installed on the top of the dust collection platform 1, two limiting discs 12 fixedly sleeved on the outer wall of the fixing seat 11, and a positioning component provided on the outer wall of the fixing seat 11.

[0019] The bottom of the positioning plate 4 is fixed with an arc-shaped sliding strip 7, the guide ring 2 is circular and the top of the guide ring 2 is provided with a sliding groove 8, and the sliding strip 7 is slidably connected in the sliding groove 8.

[0020] An adjustment plate 9 is fixedly installed on the bottom of the positioning plate 4 corresponding to the outer side of the sliding bar 7, and an adjustment handle 10 is fixedly installed on the outer side of the adjustment plate 9.

[0021] Two guide plates 17 are fixedly installed on the inner side of the adjusting plate 9. Both ends of the two guide plates 17 are arc-shaped. A V-shaped groove 18 is opened on the side of the two guide plates 17 that is close to each other, corresponding to the middle position. The positioning plate 4 rotates smoothly along the sliding groove 8 of the guide ring 2 through the bottom sliding strip 7, driving the vacuuming device 5 to rotate precisely 180 degrees around the catalyst placement platform 3. With the elastic engagement and positioning of the arched part 13 and the V-shaped groove 18 on the guide plate 17, the vacuuming head 6 can quickly switch and automatically center at both ends of the catalyst. This structure eliminates the need for manual adjustment of the catalyst, solving the problem of catalyst damage and failure caused by collision and compression in the traditional mode. At the same time, the mechanical alignment accuracy is stable, avoiding the alignment deviation of manual adjustment, ensuring that the vacuuming head and the end face are tightly fitted, and improving the consistency of cleaning effect.

[0022] There are two fixing seats 11, which are arranged symmetrically.

[0023] The positioning assembly includes an arched component 13, an L-shaped strip 14, a pressing disc 15, and a force spring 16. Two arched components 13 are slidably sleeved between two limiting discs 12. The two arched components 13 are V-shaped and symmetrically arranged. Two pressing discs 15 are slidably sleeved between the two arched components 13 on the outer wall of the fixing base 11. The two pressing discs 15 are fixed to the two arched components 13 by two L-shaped strips 14. A force spring 16 is sleeved between the two pressing discs 15 on the outer wall of the fixing base 11. By pushing or pulling the arched component 13, the pressing disc 15 can be driven to compress or release the force spring 16, realizing the quick unlocking and locking of the positioning plate 4. The operation is convenient and labor-saving. The elastic locking design ensures that the positioning plate is stable and does not loosen after rotation, avoiding displacement during dust collection and dust diffusion, improving the working environment and reducing the intensity of operation.

[0024] Working principle: Before operation, place the catalyst to be cleaned on the catalyst placement platform 3 in the center of the dust collection station 1, ensuring that the catalyst is placed stably and the end face is kept horizontal, and that the dust collection head 6 is aligned and tightly attached to one end face of the catalyst. Start the dust collection device 5, and the negative pressure airflow generated by the dust collection head 6 will suck up the dust, residue and other contaminants on the end face of the catalyst, completing the first end cleaning operation. After the dust collection of one end of the catalyst is completed, there is no need to remove the catalyst. Manually operate the adjustment structure on the two fixed seats 11: push the two arched parts 13 towards the middle. The arched parts 13 drive the extrusion plates 15 on both sides to move closer to each other along the outer wall of the fixed seat 11 through the L-bar 14. During the process, the extrusion plates 15 squeeze the force spring 16 to make it contract and deform. When the arched part 13 is completely disengaged from the V-groove 18 on the guide plate 17, the rotation limit of the positioning plate 4 is unlocked. At this time, the positioning plate 4 can rotate freely around the guide ring 2. Hold the adjustment handle 10 and drive the adjustment plate 9 and the positioning plate 4 to rotate slowly. The sliding strip 7 at the bottom of the positioning plate 4 slides along the sliding groove 8 of the guide ring 2. The dust collection device 5 rotates synchronously with the positioning plate 4 around the catalyst placement platform 3. When the positioning plate 4 drives the guide plate 17 to rotate to the position with the fixed seat 11 on the other side, the arc-shaped structures at both ends of the guide plate 17 first contact the two arched parts 13 on the fixed seat 11 on that side. Through the guiding effect of the arc surface, the two arched parts 13 are pushed closer to each other. The two arched parts 13 slide between the two guide plates 17. When the V-shaped groove 18 on the guide plate 17 is aligned with the arched parts 13, the force spring 16 releases the rebound force, pushing the extrusion plate 15, L-shaped strip 14 and arched parts 13 to reset. The middle part of the arched parts 13 is inserted into the V-shaped groove 18, realizing the locking and fixing of the positioning plate 4. At this time, the dust collection device 5 just completes a 180-degree rotation around the catalyst placement platform 3. The dust collection head 6 simultaneously turns to the other end face of the catalyst and aligns with the end face, keeping the catalyst position unchanged. The dust collection device 5 is started again, and the dust collection head 6 performs negative pressure dust collection on the other end face of the catalyst to remove contaminants from that end. After vacuuming both ends is completed, turn off the vacuuming device 5, push the arched part 13 out of the V-groove 18 according to the above unlocking steps, rotate the positioning plate 4 to the initial position, loosen the adjustment structure to lock it, and finally take out the cleaned catalyst.
