Description

Technical Field

[0001] This invention belongs to the field of chemical production technology, specifically, it relates to a particle cooling device for chemical production. Background Technology

[0002] In the chemical production processes of fertilizers, plastics, and pharmaceuticals, many raw materials or finished products (such as urea, resin, and compound fertilizer) are often produced in the form of high-temperature granules. They must be effectively cooled to a safe temperature before they can be stored, transported, or further processed. Currently, the granule cooling devices commonly used in the industry are mostly vertical cooling towers. Their basic principle is to use a cooling fan to blow room temperature or low temperature air upwards from the bottom of the tower, which then exchanges heat with the high-temperature granules falling from the top of the tower by gravity in a counter-current manner.

[0003] In related technologies, cooling towers suffer from poor cooling uniformity: particles tend to concentrate in the central area during free fall within the tower, resulting in high airflow resistance and rapid cooling in the center, while particles near the tower wall cool slowly due to stagnation, and may even cause localized overheating of the tower wall due to prolonged contact with high-temperature particles, affecting equipment lifespan and cooling effect. At the same time, the device is prone to "arching" or "bridging" phenomena at the inlet and outlet due to material moisture, static electricity, or uneven particle size, leading to poor material discharge or outlet blockage, affecting the continuity of production. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a particle cooling device for chemical production, which has the advantage of good cooling effect.

[0006] The particle cooling device for chemical production according to an embodiment of the present invention includes: A cooling tower having an inlet and an outlet, the inlet being connected to the cooling tower and located at the top of the cooling tower, and the outlet being connected to the cooling tower and located at the bottom of the cooling tower; A material discharge assembly includes a material discharge member connected to and placed inside the cooling tower. In the height direction of the cooling tower, the material discharge member is located below the inlet. The material discharge member is rotatable about a first axis and has multiple material discharge ports arranged circumferentially along the first axis. A cooling assembly is located below the material dropper in the height direction of the cooling tower. The cooling assembly includes a guide shroud arranged adjacent to the discharge port, which is used to guide the falling material to the discharge port.

[0007] In this embodiment of the invention, the material discharge component of the granule cooling device for chemical production is rotatable below the inlet, with multiple circumferentially distributed discharge ports, ensuring uniform material distribution in the cross-sectional direction and preventing central flow stream and edge stagnation. The rotating component continuously disperses and changes the material discharge position, reducing the conditions for the formation of a fixed arch bridge below the inlet. The guide shroud reduces the dead zone above the outlet by geometrically guiding and concentrating the material, and makes the material's stress state above the outlet more conducive to natural sliding, alleviating bridging and blockage. The cooling assembly provides relatively uniform gas-solid contact based on the uniform material curtain, improving cooling uniformity.

[0008] In some embodiments, the material discharge assembly further includes a flow guide, which is disposed inside the cooling tower and arranged coaxially with the material discharge assembly, and is located below the material discharge assembly. The flow guide is used to agitate the material passing through the discharge port.

[0009] In some embodiments, the flow guide includes a connecting ring and a scraper, the connecting ring being rotatably connected to the cooling tower, a first end of the scraper being connected to the connecting ring, and a second end of the scraper extending toward the wall of the cooling tower.

[0010] In some embodiments, the material feeding assembly has a first state and a second state. In the first state, the material feeding component is rotatable, and in the second state, the material feeding component and the guide component rotate simultaneously.

[0011] In some embodiments, the particle cooling device for chemical production according to the present invention further includes an arch-breaking component, the arch-breaking component including a fixed seat and a rotating seat, the rotating seat being coaxially connected to the flow guide, the fixed seat being connected to the cooling tower and located below the feed inlet, the fixed seat abutting against the rotating seat, the flow guide rotating to drive the fixed seat to rotate, the fixed seat rotating relative to the rotating seat to drive the fixed seat to move along the height direction of the cooling tower.

[0012] In some embodiments, the arch-breaking assembly further includes a ratchet portion, with the fixed seat having a ratchet portion on the side adjacent to the rotating seat and the rotating seat having a ratchet portion on the side adjacent to the fixed seat.

[0013] In some embodiments, the arch-breaking assembly further includes an elastic element located between the fixed seat and the rotating seat in the height direction of the cooling tower.

[0014] In some embodiments, the cross-sectional area of ​​the fixing seat gradually decreases in the direction from the fixing seat to the feed inlet.

[0015] In some embodiments, the cross-sectional area of ​​the guide shroud is reduced in the direction from the cooling assembly toward the feed inlet.

[0016] In some embodiments, the cooling assembly further includes a rotating component and a striking component, the rotating component having a protrusion, and the striking component abutting against the guide shroud at one end. In the height direction of the cooling tower, the rotating component rotates, and the striking component is adapted to abut against the protrusion to move the striking component toward the guide shroud.

Detailed Implementation

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figures 1-6 As shown, the particle cooling device for chemical production according to an embodiment of the present invention includes: a cooling tower 1, a material feeding assembly 2, and a cooling assembly 3.

[0026] Cooling tower 1 has a feed inlet 11 and a discharge outlet 12. The feed inlet 11 communicates with cooling tower 1 and is located at the top of cooling tower 1, while the discharge outlet 12 communicates with cooling tower 1 and is located at the bottom of cooling tower 1. The material discharge assembly 2 includes a material discharge member 21, which is connected to cooling tower 1 and placed inside cooling tower 1, along the height direction of cooling tower 1 (e.g., ...). Figure 1 The material discharge component 21 is located below the feed inlet 11 in the vertical direction of the cooling tower 1. The material discharge component 21 is rotatable about the first axis and has multiple discharge ports 211, which are arranged circumferentially along the first axis. The cooling assembly 3 is located below the material discharge component 21 in the height direction of the cooling tower 1. The cooling assembly 3 includes a guide cover 32, which is arranged adjacent to the discharge port 12 and is used to guide the falling material to the discharge port 12.

[0027] Specifically, as shown in the figure, cooling tower 1 is a vertically arranged tower shell with an internal material falling and cooling channel running from top to bottom. An inlet 11 is located at the top of the tower, and an outlet 12 is located at the bottom. The inlet 11 and outlet 12 are arranged opposite each other along the height direction, forming the main flow pattern where high-temperature particles enter from the top, are cooled inside the tower, and are discharged from the bottom. The first axial direction coincides with the vertical centerline of cooling tower 1.

[0028] The feed inlet 11 is located at the top of the cooling tower 1, and high-temperature particles are typically fed into the cooling tower 1 continuously or intermittently via upstream conveying equipment (such as belt conveyors, elevators, screw conveyors, etc.). In the vertical direction, the discharge component 21 in the discharge assembly 2 is positioned directly below the feed inlet 11. Material from the feed inlet 11 first contacts the discharge component 21, preventing it from directly forming a free-fall column within the tower. This arrangement allows the material flow entering the tower to be redistributed and dispersed immediately, creating conditions for subsequent uniform cooling.

[0029] The cooling tower 1 has a discharge port 12 at its bottom, which is connected to the cooling zone inside the tower. After cooling, the particles are discharged from the tower through this port. The guide shroud 32 in the cooling assembly 3 is located near the discharge port 12 and is adjacent to or partially covers the area of ​​the discharge port 12. It is used to gather and guide the unevenly distributed material flow along the cross-section of the tower to the discharge port 12. A certain flow channel structure is formed between the guide shroud 32 and the inner wall of the tower bottom, so that the flow trajectory of the material when it approaches the bottom of the tower is guided and organized, avoiding the formation of a static accumulation area above the discharge port 12.

[0030] The cooling assembly 3 is entirely housed within the cooling tower 1, positioned below the material discharge component 21 in the vertical direction. Material distributed by the material discharge component 21 first passes through a cooling zone (typically a fluidized or cross-flow cold air zone), then enters the lower area where the guide shroud 32 is located, and finally exits from the discharge port 12. The cooling assembly 3 may include a cold air outlet, with the guide shroud 32 positioned above the cold air outlet. The cooling tower 1 also has an air outlet 13 located at the top of the cooling tower 1.

[0031] It is understandable that, such as Figures 1-6 As shown, the material discharge component 21 is mounted on a fixed bracket of the cooling tower 1 via bearings or a support seat, forming a structure that can rotate relative to the tower body. The material discharge assembly 2 also includes a drive component 100, which can be a motor. The output shaft of the drive component 100 and the material discharge component 21 can be connected by gear transmission to drive the material discharge component 21 to rotate within the cooling tower 1.

[0032] Material entering the discharge component 21 is discharged through multiple circumferentially distributed discharge ports 211, which act as multiple diversion points in cross-section. Because the discharge ports 211 are arranged circumferentially at intervals, the material no longer falls from a single location at the center of the tower, but is dispersed to fall near different locations on the tower cross-section. The rotation of the discharge component 21 causes the falling position corresponding to each discharge port 211 to continuously change, further homogenizing the distribution of material across the tower cross-section over time and preventing long-term accumulation or falling in the same location.

[0033] In this embodiment of the invention, the material discharge component 21 of the granule cooling device for chemical production is rotatable below the inlet 11, with multiple circumferentially distributed discharge ports 211, ensuring uniform material distribution in the cross-sectional direction and preventing central flow stream and edge stagnation. The material discharge component 21 continuously disperses and changes the material discharge position through rotation, reducing the conditions for the formation of a fixed arch bridge below the inlet 11. The guide shroud 32 reduces the dead zone above the outlet 12 by geometrically guiding and concentrating the material, and makes the material more conducive to natural sliding down under pressure above the outlet, alleviating bridging and blockage. The cooling assembly 3 provides relatively uniform gas-solid contact based on the uniform material curtain, improving cooling uniformity.

[0034] In some embodiments, the material discharge assembly 2 further includes a flow guide 22, which is disposed inside the cooling tower 1. The flow guide 22 is coaxially arranged with the material discharge assembly 21 and is located below the material discharge assembly 21. The flow guide 22 is used to agitate the material passing through the discharge port 211.

[0035] Specifically, such as Figures 1-6As shown, the guide component 22 is preferably coaxially arranged with the central axis of the cooling tower 1 and the first axis of the discharge component 21, and the two are connected in space to form a continuous disturbance and distribution structure in the material falling path. On the one hand, the discharge component 21 performs the first diversion and dispersion of the material through its own rotation and multiple discharge ports 211; on the other hand, the guide component 22 located below it further disturbs and deflects the material after it passes through the discharge ports 211, changing the falling trajectory and speed distribution of the material.

[0036] The flow guide 22 can use its surface slope, arc surface, or guide ribs to laterally guide and disperse the material falling from different discharge ports 211, so that the material flow that was originally concentrated in a local vertical direction can be further expanded and evenly distributed within the cross-section of the tower. Through this coaxial series arrangement of the discharge port 21 and the flow guide 22, the material continuously undergoes the process of diversion, disturbance, and redispersion over a short distance, thereby significantly improving the uniformity of the material on the cross-section of the cooling tower 1.

[0037] Optionally, the flow guide 22 includes a connecting ring 221 and a scraper 222. The connecting ring 221 is rotatably connected to the cooling tower 1, the first end of the scraper 222 is connected to the connecting ring 221, and the second end of the scraper 222 extends toward the wall of the cooling tower 1.

[0038] Specifically, such as Figures 1-6 As shown, the connecting ring 221 can be connected to the inner peripheral wall of the cooling tower 1 via a bearing. Gears are also provided on the peripheral wall of the connecting ring 221, and the connecting ring 221 is connected to the drive component 100 via a gear transmission assembly to allow it to rotate within the cooling tower 1. Furthermore, the middle portion of the connecting ring 221 is hollowed out to facilitate material passage. The scraper 222 extends generally in the vertical direction, with its upper end connected to the connecting ring 221 and its lower end extending towards the wall of the cooling tower 1. Optionally, the scraper 222 can be arranged at an angle, and there can be multiple scrapers 222 spaced circumferentially along the first axial direction.

[0039] It is understood that the connecting ring 221 is preferably set with the central axis of the cooling tower 1 as its axis, and its inner or outer diameter is matched with the support structure set inside the cooling tower 1. It is rotatably installed inside the cooling tower 1 by means of bearings, rotating shafts or rotating supports, so that the connecting ring 221 can rotate around the tower axis relative to the shell of the cooling tower 1. Multiple scrapers 222 are arranged circumferentially along the connecting ring 221. One end of the scraper 222 is firmly connected to the connecting ring 221, and the other end extends towards the inner wall of the cooling tower 1, so that the scraper 222 moves in a circle around the tower axis under the drive of the connecting ring 221.

[0040] Since the free end of scraper 222 is close to the inner wall of cooling tower 1, during the rotation of guide member 22, the second end of scraper 222 periodically sweeps and disturbs the falling material in the area near the tower wall. On the one hand, it can scrape, move, and disperse particles that slide down or remain along the tower wall, preventing the formation of a static accumulation layer or adhesion layer near the tower wall and reducing the risk of localized long-term heating of the tower wall; on the other hand, scraper 222 appropriately lifts and turns the material near the tower wall towards the middle of the tower cross-section, so that particles that may have remained near the tower wall participate again in the overall falling and contact with the cooling airflow, thereby improving the uniformity of material distribution within the tower cross-section.

[0041] In some embodiments, the material discharge assembly 2 has a first state and a second state. In the first state, the material discharge member 21 is rotatable, and in the second state, the material discharge member 21 and the guide member 22 rotate simultaneously.

[0042] Understandably, in the first state, the material dropping component 21 is rotated around the first axis by the drive mechanism. The material dropping component 21 distributes and disperses the material falling from the feed port 11 by relying on the multiple material dropping ports 211 arranged circumferentially, so as to achieve the initial uniform distribution of the material on the cross section of the cooling tower 1. At this time, the flow guide component 22 remains relatively stationary and mainly plays the role of passively disturbing and guiding the material falling through the material dropping port 211.

[0043] In the second state, the drive component 100 drives the material discharge component 21 and the connecting ring 221 to rotate. The scraper 222 that fixes the connecting ring 221 moves accordingly, which can gently and effectively scrape away particles that may be stuck on the tower wall due to static electricity or humidity, and guide them back to the mainstream area where they fall in the center. This automatic flow guiding mechanism effectively avoids the problems of material accumulation on the tower wall and uneven cooling. At the same time, the small gap reserved between the scraper 222 and the tower wall ensures that no hard friction and wear will occur during operation. Finally, the fully and uniformly cooled granular material gathers at the bottom of the device and is stably discharged from the discharge port 12, entering the next production process, thus completing the entire efficient and continuous cooling process.

[0044] Optionally, a half-gear is provided on the output shaft of the drive component 100, and this half-gear meshes with the gear of the connecting ring 221. When the output shaft of the drive component 100 rotates, the unloading component 21 continuously rotates because it is driven by the gear set to the output shaft of the drive component 100. The connecting ring 221 only rotates when the half-gear on the output shaft of the drive component 100 meshes with the gear of the ring component. Therefore, the connecting ring 221 moves intermittently.

[0045] In some embodiments, the particle cooling device for chemical production of the present invention further includes an arch-breaking component 4. The arch-breaking component 4 includes a fixed seat 41 and a rotating seat 42. The rotating seat 42 is coaxially connected to the flow guide 22. The fixed seat 41 is connected to the cooling tower 1 and is located below the feed inlet 11. The fixed seat 41 and the rotating seat 42 abut against each other. The flow guide 22 rotates to drive the fixed seat 41 to rotate. The fixed seat 41 rotates relative to the rotating seat 42 to drive the fixed seat 41 to move along the height direction of the cooling tower 1.

[0046] Specifically, such as Figures 1-6 As shown, the rotating seat 42 is fixedly connected to the connecting ring 221 via a connecting shaft, and the rotating seat 42 is arranged correspondingly to the feed inlet 11, meaning that the rotation of the connecting ring 221 can drive the rotating seat 42 to rotate. The fixed seat 41 is connected to the inner peripheral wall of the cooling tower 1 via a connecting plate, so that the fixed seat 41 can move slightly in the vertical direction.

[0047] It is understandable that the fixed seat 41 abuts against the rotating seat 42, and the rotational motion of the rotating seat 42 can be converted into the axial movement of the fixed seat 41 through transmission forms such as inclined plane, threaded pair, eccentric structure or cam mechanism: when the guide member 22 rotates, it drives the rotating seat 42 connected to it to rotate together. During the rotation, the rotating seat 42 applies an axial component force to the fixed seat 41 through the cooperation structure between it and the fixed seat 41, so that the fixed seat 41 rotates or slides relative to the rotating seat 42, thereby driving the fixed seat 41 to move up and down along the height direction of the cooling tower 1.

[0048] Since the fixed seat 41 is located below the feed inlet 11, its periodic movement in the vertical direction is equivalent to forming a movable disturbance or supporting structure in the area below the feed inlet 11. When the material near the feed inlet 11 forms an arch or bridge in the upper part of the tower due to moisture, uneven particle size, or static electricity, the up-and-down movement of the fixed seat 41 can push, vibrate, or compress the particle layer in that area, thereby preventing the material from accumulating on the fixed seat 41. In addition, since the fixed seat 41 is located directly below the feed inlet 11, its presence can also achieve initial disturbance of the material to facilitate subsequent processing.

[0049] Optionally, the arch-breaking assembly 4 also includes a ratchet portion 43, with the fixed seat 41 having a ratchet portion 43 on the side adjacent to the rotating seat 42 and the rotating seat 42 having a ratchet portion 43 on the side adjacent to the fixed seat 41.

[0050] It is understandable that, such as Figures 1-6As shown, both the lower end of the fixed seat 41 and the upper end of the rotating seat 42 are provided with ratchet parts 43. The ratchet parts 43 cooperate with each other. When the rotating seat 42 rotates, the fixed seat 41 will move upward relative to the rotating seat 42 due to the presence of the ratchet parts 43. When the rotating seat 42 rotates to the moving position, the fixed seat 41 will move downward. This process repeats, which can vibrate and shake off the material adhering to the fixed seat 41, thereby effectively preventing the material from forming material arches or bridging near the feed inlet 11 and maintaining the continuous falling of the material.

[0051] In some embodiments, the arch-breaking assembly 4 further includes an elastic element 44, which is located between the fixed seat 41 and the rotating seat 42 in the height direction of the cooling tower 1.

[0052] It is understandable that, such as Figures 1-6 As shown, the elastic element 44 is located between the fixed seat 41 and the rotating seat 42. The elastic element 44 can be made of rubber, spring or other elastic materials and can withstand a certain pressure and deformation.

[0053] The presence of the elastic element 44 provides cushioning between the fixed seat 41 and the rotating seat 42, reducing hard friction caused by direct contact, thereby reducing wear and noise. During relative movement between the fixed seat 41 and the rotating seat 42, the elastic element 44 absorbs and reduces impact and vibration, which is beneficial for maintaining uniform material flow and cooling effect within the cooling tower 1. Furthermore, by reducing hard friction and absorbing impact, the elastic element 44 helps extend the service life of the fixed seat 41, the rotating seat 42, and other components of the cooling tower 1, reducing maintenance costs.

[0054] In some embodiments, the cross-sectional area of ​​the fixing seat 41 gradually decreases in the direction from the fixing seat 41 to the feed inlet 11.

[0055] It is understandable that, such as Figures 1-6 As shown, the cross-sectional area of ​​the fixed seat 41 gradually decreases from its bottom (near the rotating seat 42) to its top (near the feed inlet 11). Preferably, the fixed seat 41 is generally conical.

[0056] In other words, the cross-sectional area of ​​the fixed seat 41 gradually decreases, which gradually expands the space above the fixed seat 41. This helps to reduce the accumulation of material above the fixed seat 41 and avoid the formation of material arches or bridging. As the cross-sectional area of ​​the fixed seat 41 decreases, the flow resistance of the material in the area below the feed inlet 11 decreases, which is conducive to the smooth flow and uniform distribution of the material.

[0057] In some embodiments, the cross-sectional area of ​​the guide cover 32 is reduced in the direction from the cooling assembly 3 to the feed inlet 11.

[0058] It is understandable that, such as Figures 1-6 As shown, the guide shroud 32 is located at the bottom of the cooling tower 1, near the discharge port 12, and is used to guide the material to the discharge port 12. The cross-sectional area of ​​the guide shroud 32 gradually decreases from its bottom (near the discharge port 12) to its top (near the cooling assembly 3). Preferably, the guide shroud 32 is generally conical. It should be noted that the guide shroud 32 has a mesh structure, and the air outlet 13 of the cooling assembly 3 is located below the guide shroud 32 to facilitate the cooling gas to pass through the guide shroud 32 and enter the cooling tower 1. The size of the mesh openings of the guide shroud 32 should be smaller than the size of the material to prevent the material from being discharged outside the tower through the guide shroud 32.

[0059] The gradually decreasing cross-sectional area of ​​the guide shroud 32 helps guide the material flow towards the discharge port 12, ensuring smooth discharge of the material from the cooling tower 1. As the cross-sectional area of ​​the guide shroud 32 decreases, the flow resistance of the material at the bottom of the cooling tower 1 decreases, which is beneficial for uniform material distribution and cooling. The design of the guide shroud 32 helps reduce material accumulation above the discharge port 12, avoiding material blockage and ensuring continuous and stable material discharge. By optimizing material flow and airflow distribution, the design of the guide shroud 32 helps improve the cooling efficiency of the cooling tower 1, ensuring that the material can be cooled quickly and uniformly to a safe temperature.

[0060] In some embodiments, the cooling assembly 3 further includes a rotating component 33 and a striking component 34. The rotating component 33 has a protrusion 333, and one end of the striking component 34 abuts against the guide cover 32. In the height direction of the cooling tower 1, the rotating component 33 rotates, and the striking component 34 is adapted to abut against the protrusion 333 so that the striking component 34 moves toward the guide cover 32.

[0061] It is understandable that, such as Figures 1-6 As shown, the rotating component 33 is disposed within the cooling outlet 31, and the striking component 34 is connected to and adjacent to the wall of the cooling outlet 31. The rotating component 33 includes a rotating blade 331 and a rotating ring 332. The rotating ring 332 is sleeved around the rotating blade 331, and a protrusion 333 is disposed on the rotating ring 332. In the vertical direction, the striking component 34 corresponds to the edge of the rotating ring 332, and the lower end of the striking component 34 is arranged adjacent to the rotating ring 332.

[0062] In other words, when the rotating component 33 rotates, the rotating blade 331 and the rotating ring 332 rotate synchronously. Because the gap between the striking component 34 and the rotating ring 332 is small, the protrusions on the rotating ring 332 can lift the striking component 34 during its rotation. When the striking component 34 moves upward relative to the rotating ring 332, it can strike the guide cover 32. Therefore, the striking component 34 can perform continuous striking actions under the continuous rotation of the rotating component 33.

[0063] In other words, the rotation of the rotating component 33 causes its protrusion 333 to abut against the striking component 34, pushing the striking component 34 toward the guide cover 32. This movement effectively agitates and disperses the material, preventing it from accumulating at the bottom of the cooling tower 1 and ensuring that the material flows evenly to the discharge port 12. By agitating and dispersing the material, the contact area between the material and the cooling air increases, thereby improving cooling efficiency and ensuring that the material can be cooled quickly to a safe temperature. The movement of the striking component 34 helps optimize material flow, prevents blockage at the bottom of the cooling tower 1, and ensures that the material can be smoothly discharged from the cooling tower 1. The movement of the striking component 34 can reduce the accumulation of material at the bottom of the cooling tower 1, avoid material blockage, and ensure that the material can be discharged continuously and stably.

[0064] Preferably, such as Figures 1-6 As shown, the striking component 34 includes a striking base 341, a striking body 342, and a resetting member 343. The striking base 341 is connected to the cooling outlet 31. The striking body 342 extends through the striking base 341, with its lower end adjacent to the rotating ring 332 and its upper end abutting against the guide cover 32. The resetting member 343 can be a ring spring, which is fitted onto the striking body 342. The first section of the resetting member 343 abuts against the striking base 341, and the second end of the resetting member 343 abuts against the striking body 342.

[0065] In other words, after the strike body 342 is lifted, under the action of the reset member 343, the strike body 342 can move downward (i.e., return to the initial state), thereby facilitating the strike body 342 to reciprocate to strike the guide cover 32.
