Description

Technical Field

[0001] This invention belongs to the field of waste gas filtration technology, and more specifically, it relates to a fertilizer high-tower granulation device with a waste gas filtration device. Background Technology

[0002] High-tower granulation is a new process for compound fertilizer production. It involves dissolving and granulating various raw materials in a high tower, then spraying them into the tower through nozzles. The granules cool naturally as they fall, forming compound fertilizer granules, which are then screened multiple times before being packaged and sold.

[0003] During the high-tower granulation process, a large amount of waste gas is generated, which contains incompletely granulated powdery particles. These powdery particles are processed along with the waste gas in the waste gas treatment equipment. Before the waste gas is treated, these powdery particles need to be filtered to prevent them from affecting the quality of subsequent waste gas treatment and to allow for their recycling. Existing technologies, such as the collection bag method mentioned in patent publication CN215276243U and the activated carbon method mentioned in patent publication CN215276566U, can effectively intercept powdery particles, but neither method has an automatic cleaning function, requiring manual replacement of the filter media. Although patent publication CN215276566U uses a labor-saving structure to reduce manual labor to some extent, manual replacement of consumables is still necessary. Furthermore, both patent documents use only one filtration method to filter powdery particles, which not only results in low filtration efficiency but also increases the workload of the filter media, requiring frequent cleaning or replacement, further increasing labor costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fertilizer high-tower granulation equipment with a waste gas filtration device. By adding a granular filter module with a self-cleaning function to the front end of the traditional activated carbon filter material, the two form a multi-stage filtration structure, which can effectively improve the filtration of powder particles, reduce labor costs, and improve the recycling and reuse of powder particles.

[0038] The present invention will be further described below with reference to the accompanying drawings:

[0039] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] like Figures 1 to 3 As shown, a fertilizer high-tower granulation device with an exhaust gas filtration device includes a main body 1, a granulation device 11 inside the main body 1, and an exhaust gas filtration device 12 located at the top of the main body 1. The exhaust gas filtration device 12 includes a gas treatment device 2, which internally defines a neutralization chamber 21, a suction chamber 22, and a drive chamber 23, and the three chambers are sequentially connected. The drive chamber 23 contains a multi-purpose drive assembly 24. One side of the gas treatment device 2 has multiple particle filtration modules 3, with valve bodies 4 fixed at both ends. One end of the module is connected to the suction chamber 22, and some components are rotatably connected to the multi-purpose drive assembly 24. The exhaust gas filtration device 12 contains a longitudinal main shaft 221 rotatably connected to the drive chamber 23, the suction chamber 22, and the neutralization chamber 21, and one end of the longitudinal main shaft 221 is rotatably connected to the multi-purpose drive assembly 24. In this way, the exhaust gas filtration device 12 generates suction force during operation, drawing the exhaust gas generated in the granulation device 11 within the main body 1 into the particulate filter module 3. The particulate filter module 3 consists of multiple modules arranged in parallel. When one particulate filter module 3 is closed via the valve body 4 and automatically performs internal cleaning, at least one particulate filter module 3 is in filtration operation. This not only ensures the continuity of exhaust gas filtration but also improves the filtration quality and efficiency. The filtered exhaust gas is then transported through the suction chamber 22 to the neutralization chamber 21 for neutralization liquid atomization treatment, effectively rendering the exhaust gas harmless. The longitudinal main shaft 221 running through the drive chamber 23, suction chamber 22, and neutralization chamber 21 enables synchronous operation of the three without the need for additional driving force. Through high integration, it achieves higher working efficiency within a limited space.

[0041] Optionally, multiple parallel suction pipes 101 are fixed to the outer wall of the main body 1, and one end of each suction pipe 101 is fixedly connected to the particulate filter module 3. Each suction pipe 101 is fixed with multiple manifolds 102 communicating with its interior, and one end of each manifold 102 extends into the main body 1. In this way, exhaust gas can be sucked from multiple directions through multiple manifolds 102, thereby improving the exhaust gas suction efficiency.

[0042] Optionally, a recovery pipe 103 is connected to the bottom of the particulate filter module 3, and the other end of the recovery pipe 103 extends to the bottom of the main body 1 and connects to the recovery system. In this way, the cleaned powdery particles can be connected to the recovery system through the recovery pipe 103 for centralized recycling and reuse, thereby effectively reducing production costs.

[0043] like Figure 3 and Figure 4 As shown, the multi-purpose device includes a drive motor 241 and a first electric push rod 242. The drive motor 241 has a first conical wheel 243 on its top, and a first friction disc 244 is fixed to the top of the first conical wheel 243. A sliding bracket 245 is fixed to the outside of the drive motor 241, and parallel slide rails 246 are located on both sides of the bottom of the sliding bracket 245. The first electric push rod 242 is disposed on one side of the sliding bracket 245, with one end fixedly connected to the sliding bracket 245. A first transverse main shaft 247 is provided on the side wall of the drive cavity 23, with one end protruding outside the drive cavity 23 and rotatably connected to the particulate filter module 3, and the other end fixed with a second conical wheel 248, which meshes with the first conical wheel 243 as needed. Thus, with the cooperation of the sliding bracket 245 and the first electric push rod 242, the drive motor 241 can slide along the sliding bracket 245, allowing the drive motor 241 to be linked with different drive components. For example, when the drive motor 241 moves toward the first electric push rod 242, the first friction disc 244 is adapted to connect with the longitudinal main shaft 221 and drives the longitudinal main shaft 221 to rotate, thereby driving the components in the suction chamber 22 and neutralization chamber 21 to operate normally. Conversely, when the drive motor 241 moves away from the first electric push rod 242, the first conical wheel 243 meshes with the end of the first transverse main shaft 247 and drives the particulate filter module 3 to operate, enabling the particulate filter module 3 to complete the closing of the valve body 4 and the internal cleaning work.

[0044] like Figure 5 As shown, the bottom of the sliding bracket 245 is provided with a first through groove 2451, and a second through groove 2452 is provided on one side, and the first through groove 2451 and the second through groove 2452 are connected.

[0045] like Figures 4 to 7As shown, a lifting assembly 250 is provided between the slide rails 246, consisting of a lifting seat 251 and a linkage hydraulic cylinder 252. The lifting seat 251 is fixedly connected to the bottom of the drive chamber 23 and is located below the drive motor 241. The linkage hydraulic cylinder 252 is located on one side of the first electric push rod 242, and has a reservoir cylinder 2521 inside. One end of the reservoir cylinder 2521 is fitted with a piston rod 2522, and a connecting rod 2523 is fixed between one end of the piston rod 2522 and the movable end of the first electric push rod 242. A connecting pipe 2524 is provided at the end of the reservoir cylinder 2521 facing away from the piston rod 2522, and the connecting pipe 2524 is connected to the lifting seat 251. In this way, one end of the piston rod 2522 is linked to the movable end of the first electric push rod 242 through the connecting rod 2523. When the first electric push rod 242 pulls the drive motor 241 toward itself, the piston rod 2522 squeezes the liquid in the reservoir 2521, conveying the liquid through the connecting pipe 2524 to the lifting seat 251, so that the lifting part 2511 of the lifting seat 251 contacts the drive motor 241 and lifts the drive motor 241. As the drive motor 241 is lifted, its first friction disc 244 is adapted to connect with the longitudinal main shaft 221, achieving the purpose of driving the longitudinal main shaft 221. Conversely, when the first electric push rod 242 pushes the drive motor 241 away from itself, the piston rod 2522, which is connected to the movable end of the first electric push rod 242, draws the liquid in the lifting seat 251 back into the reservoir 2521, so that the lifting force of the lifting seat 251 on the drive motor 241 gradually decreases. At this time, the first friction disc 244 separates from the longitudinal spindle 221, thereby achieving the purpose of disconnecting the drive motor 241 from the longitudinal spindle 221.

[0046] Optionally, the piston rod 2522, the liquid storage cylinder 2521 and the connecting pipe 2524 are wrapped with a protective shell 2525, and the top of the protective shell 2525 is provided with a sliding groove 2526 for sliding of the connecting rod 2523.

[0047] like Figure 3 and 8 As shown, a turbine fan 223 and an inertia wheel 224 are fixed on the longitudinal main shaft 221. The turbine fan 223 is located in the suction chamber 22, and the inertia wheel 224 is located in the neutralization chamber 21. One end of the inertia wheel 224 is fixed with an injection pipe 225. Thus, the inertia wheel 224 and turbine fan 223 are fixedly connected to the longitudinal main shaft 221 and can rotate synchronously with it. According to the law of conservation of angular momentum, the kinetic energy of the inertia wheel 224 is stored as mechanical energy in its rotational inertia during rotation with the longitudinal main shaft 221. When the drive motor 241 is disconnected from the longitudinal main shaft 221, the inertia wheel 224 continues to rotate due to inertia, converting the stored energy into mechanical motion, simultaneously driving the longitudinal main shaft 221 to rotate, ensuring that the turbine fan 223 can operate normally and generate suction force.

[0048] Understandably, when the drive motor 241 is connected to and drives the longitudinal main shaft 221 to rotate, the drive motor 241 provides the primary driving force. When the drive motor 241 briefly separates from the longitudinal main shaft 221 to drive the particulate filter module 3, the inertia wheel 224, relying on inertia, briefly acts as a secondary driving force to drive the longitudinal main shaft 221. This ensures that the turbine fan 223 maintains stable operation while the drive motor 241 drives the particulate filter module 3. After the particulate filter module 3 completes its self-cleaning process, the drive motor 241 reconnects to the longitudinal main shaft 221 and drives it to rotate. At this time, the inertia wheel 224 restores mechanical energy for the next power replacement.

[0049] like Figure 3 As shown, a second friction disc 222 is fixed to one end of the longitudinal main shaft 221 facing the drive motor 241, and the second friction disc 222 abuts against the first friction disc 244 at appropriate times. Thus, the operation of the inertia wheel 224 and the turbine fan 223 requires a certain inertia or rotational speed to maintain, therefore the drive motor 241 needs to accelerate the rotational speed of the longitudinal main shaft 221 to a certain speed. However, the rotational speed required for the particulate filter module 3 to operate does not require a high rotational speed compared to the inertia wheel 224 and the turbine fan 223. Therefore, when the drive motor 241 switches from connecting to the longitudinal main shaft 221 to connecting to the particulate filter module 3, it needs to decelerate to reach the rotational speed required for the particulate filter module 3 to operate. Before the drive motor 241 reconnects to the longitudinal main shaft 221, it needs to increase its rotational speed to approximately the same as that of the longitudinal main shaft 221 to enable instantaneous connection. During this process, as the mechanical energy of the inertia wheel 224 is continuously released, its rotational speed decreases linearly. When the drive motor 241 is momentarily connected to the longitudinal spindle 221, a significant instantaneous lateral impact force is generated due to the speed difference between the two. If a gear connection is used, this impact force may damage the gears. However, with a friction connection, there is no need to consider the damage to the first friction disc 244 and / or the second friction disc 222 caused by the instantaneous lateral impact force, as their contact surfaces are planar. A certain amount of heat is generated upon contact. When the drive motor 241 is lifted into position by the lifting assembly, the first friction disc 244 and the second friction disc 222 reach their maximum contact force, maintaining a stable connection. At this time, the second friction disc 222 rotates synchronously with the first friction disc 244.

[0050] like Figure 8As shown, the inertia wheel 224 is provided with multiple connecting grooves 2241, one end of which is connected to the side wall of the inertia wheel 224, and the other end is connected to the end provided with the liquid injection pipe 225. In this way, the neutralizing liquid enters the connecting groove 2241 through the liquid injection pipe 225, and is thrown out along its tangent by the centrifugal force of the inertia wheel 224 rotating at high speed. After forming a thin film, it breaks into atomized droplets, so that the atomized neutralizing liquid fills the entire neutralization chamber 21, thereby achieving the purpose of neutralizing the waste gas.

[0051] Optionally, multiple atomizing plates 2242, arranged at intervals and surrounding the inertia wheel 224, are fixed at positions adjacent to its periphery. In this way, when the inertia wheel 224 acts as a second driving force and its rotational speed decreases, making it difficult to atomize the neutralizing liquid, the atomizing plates 2242 use centrifugal force to throw the neutralizing liquid onto the surface of the atomizing plates 2242, assisting the atomization process through impact. This ensures the effective harmless treatment of the exhaust gas within the neutralization chamber 21.

[0052] Optionally, the surface of the atomizing plate 2242 is provided with a plurality of through holes for atomization.

[0053] Optionally, below the inertia wheel 224, a reduction chamber 211 communicating with the neutralization chamber 21 is provided. Multiple partitions on its inner side define its interior as a reducing agent placement tank 2111 and a storage tank 2112. Thus, the used neutralizing liquid in the neutralization chamber 21 reacts with the exhaust gas and enters the reducing agent placement tank 2111 within the reduction chamber 211, where it reacts with the placed reducing agent to revert to neutralizing liquid. The reverted neutralizing liquid is then stored in the storage tank 2112.

[0054] Optionally, a filter screen 2113 is installed between the reducing agent placement tank 2111 and the liquid storage tank 2112.

[0055] Optionally, a pump body 2114 is installed on the outer wall of the neutralization chamber 21, with one end of the pump body 2114 connected to the liquid storage tank 2112 and the other end connected to the injection pipe 225. In this way, the reduced neutralized liquid can be transported to the injection pipe 225 for reuse through the pump body 2114.

[0056] Optionally, the side wall of the reduction chamber 211 is provided with multiple sealing doors 2115 for adding reducing agent into the reducing agent placement tank 2111.

[0057] Optionally, an inlet pipe 2101 communicating with the suction chamber 22 is fixed to one side of the neutralization chamber 21, and an exhaust pipe 2102 is fixed to the other side, with a gas-liquid separation filter box 2103 fixed on the exhaust pipe 2102. In this way, the gas-liquid separation filter box 2103 can separate the waste gas about to be discharged from the neutralization chamber 21, so as to reduce the amount of neutralized liquid discharged with the waste gas.

[0058] like Figures 9 to 11 As shown, the particulate filtration module 3 includes an adsorption cylinder 31, and multiple adsorption plates 32 are slidably connected to the side wall of the adsorption cylinder 31, with one end of each adsorption plate 32 protruding into the adsorption cylinder 31. Multiple sets of springs 33 are also provided on the side wall of the adsorption cylinder 31, one end of which is fixedly connected to the outer wall of the adsorption cylinder 31, and the other end is fixedly connected to the adsorption plate 32. A scraping assembly 34 is rotatably connected to one end of the adsorption cylinder 31. A discharge channel 311 is provided on the side wall of the adsorption cylinder 31, and a portion of the scraping assembly 34 can close the discharge channel 311 as needed. In this way, the adsorption area can be effectively increased by extending the adsorption plates 32 into the adsorption cylinder 31. When the scraping component 34 reaches the position of each adsorption plate 32, the adsorption plate 32 is pushed out of the adsorption cylinder 31 by the scraping component 34. During the movement of the adsorption plate 32 out of the adsorption cylinder 31, the outer wall of the adsorption plate 32 scrapes against the outer wall of the adsorption cylinder 31, which can remove the powder particles adsorbed on the outer wall of the adsorption plate 32. After the scraping component 34 passes the adsorption plate 32, the adsorption plate 32 will return to the adsorption cylinder 31 under the tension of the spring 33. At the same time, the powder particles adsorbed on the inner wall of the adsorption cylinder 31 are scraped off by the scraping component 34. The scraped powder particles fall into the discharge channel 311 under the action of gravity and are discharged out of the adsorption cylinder 31. After the scraping component 34 completes the cleaning work of the adsorption cylinder 31, the scraping component 34 will seal the discharge channel 311 to prevent the exhaust gas from escaping out through the discharge channel 311 during the exhaust gas adsorption process.

[0059] Optionally, the portion of the adsorption plate 32 located outside the adsorption cylinder 31 has guide blocks 321 fixed at its parallel ends, and the guide blocks 321 have an arc-shaped structure in the direction of movement of the scraping component 34. In this way, by using the guide blocks 321 with arc-shaped structures, the adsorption plate 32 can be pushed out of the adsorption cylinder 31 more easily when the scraping component 34 comes into contact with the adsorption plate 32.

[0060] Optionally, two adjacent particle filtration modules 3 are respectively a first module 301 and a second module 302, wherein the length of the first module 301 is greater than the length of the second module 302.

[0061] Optionally, the outer wall of the adsorption cylinder 31 is provided with a groove 3112 surrounding it, and the groove 3112 is adapted to be connected to the scraping assembly 34.

[0062] like Figure 12 and Figure 14As shown, the scraping assembly 34 includes a connecting wheel 341 and a turntable 342. One end of the turntable 342 is fixedly connected to the connecting wheel 341, and the other end is rotatably connected to one end of the adsorption cylinder 31. A scraper 3421 that abuts against the inner wall of the adsorption cylinder 31 is fixed on one side of the turntable 342. A prying frame 344 that slides along the outer wall of the adsorption cylinder 31 is fixed on the side wall of the turntable 342, and multiple pry bars 3441 that abut against the adsorption plate 32 at appropriate times are fixed on the inner side of the prying frame 344. The prying frame 344 and the scraper 3421 are staggered in the vertical direction. In this way, during the rotation of the turntable 342, the prying frame 344 and the scraper 3421 rotate synchronously with the turntable 342. When the prying frame 344 moves to one side of one of the adsorption plates 32, the rocker arms 3441 fixed on both sides contact the guide block 321, causing the guide block 321 to move the adsorption plate 32 along the rocker arms outward from the adsorption cylinder 31. When the guide block 321 moves the adsorption plate 32 to the highest point of the rocker arms 3441, the end of the adsorption plate 32 facing the inside of the adsorption cylinder 31 is flush with the inner wall of the adsorption cylinder 31. At the same time, the scraper 3421, which is in contact with the inner wall of the adsorption cylinder 31, moves to the position where the adsorption plate 32 is located inside the adsorption cylinder 31. This scrapes the end of the adsorption plate 32 while also preventing the adsorption plate 32 from returning to its original position. After the scraper 3421 passes the end of the adsorption plate 32, the adsorption plate 32 returns to its original position inside the adsorption cylinder 31 under the tension of the spring 33.

[0063] Optionally, a first reinforcing rod 3431 and a second reinforcing rod 3432 are fixed on the side of the turntable 342 facing away from the connecting wheel 341. Through the cooperation of the first reinforcing rod 3431 and the second reinforcing rod 3432, the scraper 3421 can be effectively fixed, so that the scraper 3421 can maintain a tight contact with the inner wall of the adsorption cylinder 31, so as to ensure the cleaning effect on its inner wall.

[0064] Optionally, due to the length of the first module 301 and the second module 302, the connecting wheel 341 provided in the first module 301 and the connecting wheel 341 provided in the second module 302 are arranged in a staggered manner.

[0065] Optionally, one end of the prying frame is provided with a protrusion 3441, and the protrusion 3441 is slidably connected to the slide groove 3112.

[0066] like Figure 14As shown, the valve body 4 has a sealing plate 41 embedded inside, which is fixedly connected to a rotating seat 42 disposed on the outer wall of the valve body 4, and the sealing plate 41 rotates with the rotating seat 42; multiple uprights 421 are fixed on the side wall of the rotating seat 42; multiple connecting plates 43 are fixed on the outer wall of the valve body 4 for connecting another valve body 4, and a first linkage device 44 is provided on one side of one of the connecting plates 43. In this way, through the first linkage device 44, in cooperation with the rotating seat 42, the sealing plate 41 embedded in the valve body 4 can be rotated, thereby achieving the purpose of closing or opening the port of the particulate filter module 3.

[0067] Optionally, valve bodies 4 are fixed at both ends of the particulate filter module 3, and a three-way pipe 45 is fixed at the end of the valve body 4 on the same side facing away from the particulate filter module 3.

[0068] Optionally, a secondary particulate filter box 451 is fixed to one end of one of the three-way pipes 45, and the secondary particulate filter box 451 is connected to the suction chamber 22. In this way, the secondary particulate filter box 451 can capture particles that are not filtered out by the particulate filter module 3, so as to reduce the possibility of particles entering the suction chamber 22.

[0069] Optionally, one end of the upright post 421 is provided with a roller 422, and the roller 422 is rotatably connected to the upright post 421.

[0070] Optionally, the sealing plates 41 inside two adjacent valve bodies 4 are perpendicular to each other, that is, the sealing plate 41 of one valve body 4 is in a closed state, and the sealing plate 41 of the other valve body 4 is in an open state.

[0071] like Figure 15 As shown, the first linkage device 44 includes a limiting plate assembly 441, a first slider 442, a limiting strip 443, and a second slider 444. The limiting plate assembly 441 is fixed to the middle of the connecting plate 43, and limiting strips 443 are fixed on both sides of it. The first slider 442 is slidably connected to the limiting plate assembly 441, and levers 4421 protruding towards the rotating seat 42 are fixed on both parallel sides of the first slider 442. The second slider 444 is slidably connected to the limiting strips 443, and the middle of the second slider 444 is fixedly connected to the levers 4421. The end of the lever 4421 facing the rotating seat 42 abuts against the upright 421 at appropriate times. In this way, the limiting plate assembly 441 and the limiting strips 443 can limit and guide the first slider 442 and the second slider 444, so that the first slider 442 and the second slider 444 can slide along the limiting plate assembly 441 and the limiting strips 443 respectively, and are not prone to deviation during the sliding process. At the same time, the second slider 444 also supports the lever 4421, preventing the lever 4421 from bending due to its large span.

[0072] like Figures 16 to 17 As shown, a second linkage device 5 is fixed to one side of the particulate filter module 3, consisting of a second electric push rod 51, a second transverse main shaft 52, and a drive gear 53. The second electric push rod 51 is fixed to one side of the particulate filter module 3, and a second connecting plate 511 is fixed to its telescopic end. One end of the second connecting plate 511 is rotatably connected to the second transverse main shaft 52. One end of the second transverse main shaft 52 is provided with a spline 522 adapted to and connected to the first transverse main shaft 247. A first connecting plate 521 is rotatably connected between the spline 522 and the second connecting plate 511, and the first connecting plate 521 is fixedly connected to the first slider 442. The other end of the second transverse main shaft 52 is provided with a third connecting plate 512 rotatably connected, and the other end of the third connecting plate 512 is fixedly connected to another first slider 442. A drive gear 53 is fixed between the third connecting plate 512 and the second connecting plate 511, and the drive gear 53 meshes with multiple linkage wheels 341 as needed. In this way, the second electric push rod 51, in cooperation with the second transverse main shaft 52, can drive the first connecting plate 521, the third connecting plate 512, and the drive gear 53 connected thereto to move synchronously, so that the valve bodies 4 at both ends of the particulate filter module 3 are linked with the drive gear 53. When the second electric push rod 51 drives the second transverse main shaft 52 to move toward the first connecting plate 521, the valve bodies 4 at both ends of one particulate filter module 3 close, while the valve bodies 4 at both ends of the other particulate filter module 3 open. At the same time, the drive gear 53 meshes with the linkage wheel 341 of the particulate filter module 3 with its valve body 4 closed. Conversely, when the second transverse main shaft 52 moves toward the third connecting plate 512, the originally open valve body 4 is switched to the closed state, and the drive gear 53 meshes with the linkage wheel 341 of this particulate filter module. In addition, the second transverse main shaft 52, through the spline 522, can be telescopically connected to the first transverse main shaft 247 while maintaining synchronous rotation.

[0073] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
