Description

Technical Field

[0001] This invention relates to the field of polyethylene synthesis technology, and more particularly to a stripping kettle trap for use in the synthesis of ultra-high molecular weight polyethylene. Background Technology

[0002] In the synthesis process of ultra-high molecular weight polyethylene (UHMWPE), the stripping reactor is used to remove solvents and unreacted monomers. The gas discharged from the reactor carries polymer particles, solvent droplets, and other media. If these entrained materials are directly discharged or enter subsequent systems, they will not only cause product loss and environmental pollution but may also clog pipelines and damage equipment. Therefore, it is necessary to install a collector at the exhaust port of the stripping reactor to recover materials and purify the gas.

[0003] Traditional stripping reactor traps mostly employ static baffles, filters, or simple cyclone separation structures. These structures have the following shortcomings: for mixed media of ultra-high molecular weight polyethylene particles with a wide particle size distribution and high viscosity, and solvent droplets, the separation efficiency of a single static structure is limited, especially for the poor capture effect of tiny particles and mist droplets;

[0004] The captured material tends to adhere to and accumulate on the surface of internal components, and the complex internal structure makes manual cleaning very difficult, often requiring machine shutdown and disassembly, which seriously affects production continuity and efficiency.

[0005] Therefore, there is an urgent need to design a stripping kettle collector that is highly efficient, not prone to clogging, and easy to clean and maintain online, in order to meet the needs of continuous, efficient, and stable operation in the ultra-high molecular weight polyethylene synthesis industry. Summary of the Invention

[0006] To address the problems mentioned in the background section, the present invention provides a stripping reactor trap for use in the synthesis of ultra-high molecular weight polyethylene.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A stripping reactor trap for the synthesis of ultra-high molecular weight polyethylene includes a trapping tank. The top of the trapping tank is provided with an exhaust port, the bottom of the exhaust port is provided with a liquid discharge port, and an air inlet is provided on one side of the trapping tank near the bottom. A dynamic baffle is rotatably installed inside the trapping tank. The dynamic baffle includes a rotating ring. Multiple first baffles are distributed in a ring array at the top of the rotating ring, and the air inlet corresponds to the first baffles.

[0009] The dynamic blocker has a static blocker located above it, and a filter screen is installed in the exhaust port.

[0010] Preferably, the static barrier includes multiple equally spaced barrier discs with multiple rectangular openings. Two second baffles are rotatably mounted below the barrier discs. The two second baffles are in close contact on their adjacent sides, and when the second baffles are rotated to a horizontal position, a gap is left between their top ends and the bottom ends of the barrier discs for the flushing liquid to pass through.

[0011] Preferably, the top of the static blocker has a rectangular lifting groove on the outside of the rectangular opening, and an air guide frame is slidably installed in the rectangular lifting groove.

[0012] Preferably, a drive shaft is rotatably installed inside the collection tank. The drive shaft moves through multiple blocking discs, and a connecting strip is fixed above each blocking disc. A sliding inner ring is fixed on the connecting strip, and a mating outer ring is fixed between the top ends of multiple air guide frames. An annular groove is opened inside the mating outer ring, and the edge of the sliding inner ring extends into the annular groove.

[0013] Preferably, the top end of the drive shaft is rotatably connected to the lifting bracket, and a first cleaning brush is fixed to the top end of the drive shaft, the first cleaning brush corresponding to the filter screen.

[0014] Preferably, a hydraulic cylinder is fixed on the inner wall of the top of the collection tank, the output end of the hydraulic cylinder is fixed to the lifting bracket, and a vertical rack is fixed to the bottom of the outer ring. The vertical rack passes through the blocking disc and extends to the bottom of the blocking disc.

[0015] Preferably, a first spur gear and a second spur gear are fixed on the mounting shafts of the two second baffles, respectively, and the first spur gear and the second spur gear mesh with each other. A third spur gear is fixed on the second spur gear, and the third spur gear meshes with the vertical rack.

[0016] Preferably, the first spur gear and the second spur gear have the same diameter, and the diameter of the third spur gear is larger than that of the second spur gear.

[0017] Preferably, the collection tank is provided with two power transmission boxes inside. A vertical shaft is rotatably installed inside the power transmission box. The top of the vertical shaft in the lower power transmission box is fixed to the rotating ring. A polygonal pin is fixed to the top of the vertical shaft in the upper power transmission box. The top of the polygonal pin extends movably into a groove opened at the bottom of the drive shaft.

[0018] Preferably, a power input shaft is rotatably mounted on the power transmission box. A first bevel gear is fixed to one end of the power input shaft, and a second bevel gear is fixed to the bottom end of the vertical shaft. The first bevel gear meshes with the second bevel gear, and the other end of the power input shaft is fixed to a synchronous pulley through a one-way transmission device. A synchronous belt is sleeved between the outer sides of the two synchronous pulleys, and one of the synchronous pulleys is fixed to the output shaft of the rotary motor.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention employs a multi-stage composite separation design, consisting of a dynamic barrier, a static barrier, and a filter screen. The dynamic barrier utilizes a rotating first baffle to perform initial inertial separation of the high-speed intake air, effectively intercepting large-diameter particles and droplets. The gas then enters the static barrier, where a special flow channel formed by the air guide frame and a movable second baffle forces the gas to undergo multiple directional abrupt reversals. The inertial effect causes remaining tiny particles and fine droplets to repeatedly collide with and adhere to the baffle surface, achieving highly efficient, tiered capture of particles and droplets of multiple scales. Finally, the exhaust gas undergoes fine filtration through a filter screen at the exhaust port, ensuring the cleanliness of the discharged gas.

[0021] 2. Through a linkage design, the equipment can switch between working and cleaning modes. When cleaning is required, the lifting mechanism drives the drive shaft to move downwards. Through the linkage of the vertical rack and pinion and gear set, all second baffles are driven to rotate synchronously to a horizontal position, while the air guide frame descends to be flush with the blocking plate. At this time, the rotation of the drive shaft drives the second and third cleaning brushes on it, which can simultaneously perform a comprehensive mechanical scrubbing of the surface of the horizontally unfolded second baffles and the surfaces of the upper and lower blocking plates. The entire process does not require disassembly of internal components, realizing online, efficient, and automatic cleaning, greatly reducing maintenance difficulty and downtime.

[0022] 3. The lifting and lowering of the air guide frame and the opening and closing of the second baffle are mechanically linked through a rack and pinion mechanism, ensuring synchronous and reliable state switching without the need for a separate drive source for the cleaning function. The power transmission system uses a unidirectional drive in conjunction with a single rotary motor. By rotating the motor in both forward and reverse directions, the dynamic baffle can be driven to rotate (for separation) and the shaft can be driven to rotate (for cleaning), respectively. This achieves single-power-source control of multiple core functions, simplifying the control system and reducing energy consumption and equipment complexity. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] Reference Figure 1-17 A stripping reactor trap for the synthesis of ultra-high molecular weight polyethylene includes a trapping tank 1. The top of the trapping tank 1 is provided with an exhaust port 101, the bottom of the exhaust port 101 is provided with a drain port 103, and an air inlet 102 is provided on one side of the trapping tank 1 near the bottom. A dynamic baffle is rotatably installed inside the trapping tank 1. The dynamic baffle includes a rotating ring 6. Multiple first baffles 601 are distributed in a ring array at the top of the rotating ring 6, and the air inlet 102 corresponds to the first baffles 601.

[0045] A static blocker 3 is provided above the dynamic blocker, and a filter screen 1011 is installed in the exhaust port 101.

[0046] The inlet 102 is connected to the outlet of the gas vessel through a pipe. The multiphase mixed medium enters the collection tank 1. The gas first blows towards the dynamic baffle. The rotating ring 6 rotates, which drives the first baffle 601 to rotate as well. When the high-speed mixed medium blows towards the rotating first baffle 601, on the one hand, the airflow is forced to change direction due to the mechanical obstruction of the first baffle 601, forming a rotating turbulence and prolonging the residence time of the medium in this area. On the other hand, the rotational inertia of the first baffle 601 interacts with the impact force of the airflow, causing large-diameter polymer particles and condensed solvent droplets in the mixed medium to be unable to flow around the baffle with the airflow due to their greater inertia than the gas phase components. Instead, they directly impact the surface of the rotating first baffle 601.

[0047] After impact, the solid particles and droplets slide to the bottom of the collection tank 1 under the combined action of centrifugal force and gravity. Some droplets can be discharged and recovered in advance through the drain port 103 after aggregation. The gaseous medium (still containing tiny particles and fine droplets) after preliminary separation is guided upward by the rotating airflow and enters the subsequent static barrier 3 area to complete the dynamic coarse separation stage.

[0048] The gas is blocked again by the static barrier 3, which can intercept the remaining tiny particles and fine droplets. The gas is finally filtered by the filter screen 1011 and discharged from the exhaust port 101.

[0049] Example 2

[0050] Reference Figure 1-17 The difference between this embodiment and embodiment 1 is that the static blocker 3 includes multiple equally spaced blocking discs 301, and multiple rectangular openings 3011 are provided on the blocking discs 301. Two second baffles 4 are rotatably installed below the blocking discs 301. The two second baffles 4 are in close contact with each other on their sides. When the second baffles 4 are rotated to the horizontal, a gap is left between their top end and the bottom end of the blocking discs 301 for the flushing liquid to pass through. A rectangular lifting groove 3012 is provided on the top of the static blocker 3 outside the rectangular opening 3011. An air guide frame 3013 is slidably installed in the rectangular lifting groove 3012.

[0051] The second baffle 4 has two position states, and the air guide frame 3013 also has two position states, such as Figure 16 and Figure 17 The state shown:

[0052] When the second baffle 4 is tilted and the air guide frame 3013 is raised to its highest position, it is in the working state. (Refer to...) Figure 12As shown, the air guide frame 3013 rises between the two second baffles 4, and a gap is left between the side edge of the air guide frame 3013 and the second baffles 4 for gas to flow through. There is also a gap between the top of the included angle formed by the two second baffles 4 and the rectangular opening 3011. The gas flowing from bottom to top first blows towards the bottom of the second baffles 4, and then flows downward, flowing downward from the gap between the side edge of the air guide frame 3013 and the second baffles 4, and then flows upward again, flowing into the rectangular opening 3011 from the gap between the top of the second baffles 4 and the rectangular opening 3011 to enter the next stage. The gas will continuously flow back and forth and hit the second baffles 4 multiple times. During the entire flow process, the gas completes three directional changes: upward impact, downward back, upward guidance and merging into the rectangular opening 3011, forming a continuous backflow field. During this process, the tiny particles and fine droplets in the gas cannot change their flow direction in time due to inertia, and will hit the second baffles 4 and the blocking disk 301 multiple times, thereby intercepting the remaining tiny particles and fine droplets.

[0053] When the second baffle 4 is in a horizontal state and the air guide frame 3013 is lowered to its lowest position, it is in a cleaning state. Since the air guide frame 3013 retracts into the rectangular lifting groove 3012 and is flush with the surface of the blocking plate 301, the second baffle 4 is also in a horizontal state and parallel to the lower surface of the second baffle 4. At this time, the surface of the second baffle 4 and the blocking plate 301 can be easily brushed with a brush, resulting in higher cleaning efficiency and better cleaning effect.

[0054] The collection tank 1 contains a rotatable drive shaft 201 that movably passes through multiple baffles 301. A connecting strip 302 is fixed above each baffle 301 on the drive shaft 201. A sliding inner ring 3024 is fixed to the connecting strip 302. A mating outer ring 3014 is fixed between the top ends of multiple air guide frames 3013. An annular groove is formed inside the mating outer ring 3014. The edge of the sliding inner ring 3024 extends into the annular groove. A second cleaning brush 3023 is fixed to the bottom end of the connecting strip 302. The top end of bar 302 is connected to a third cleaning brush 3022 via an elastic telescopic rod 3021. The top end of drive shaft 201 is rotatably connected to lifting bracket 2. The top end of drive shaft 201 is fixed with a first cleaning brush 203, which corresponds to filter screen 1011. A hydraulic cylinder 202 is fixed on the inner wall of the top end of collection tank 1. The output end of hydraulic cylinder 202 is fixed to lifting bracket 2. A vertical rack 3015 is fixed at the bottom end of outer ring 3014. The vertical rack 3015 passes through the blocking plate 301 and extends to the bottom of the blocking plate 301.

[0055] In the cleaning state, the hydraulic cylinder 202 extends, thereby driving the lifting bracket 2 to move upward, which in turn drives the drive shaft 201 to move upward, thereby driving the sliding inner ring 3024 and the mating outer ring 3014 to move upward, thus driving the air guide frame 3013 to move to the lowest position. The rotation of the drive shaft 201 will cause the connecting bar 302 to rotate as well, thereby driving the second cleaning brush 3023 and the third cleaning brush 3022 to brush the top and bottom of the blocking plate 301 and the surface of the second baffle 4. The presence of the elastic telescopic rod 3021 ensures that during the downward movement of the connecting bar 302, the elastic telescopic rod 3021 can push the third cleaning brush 3022 to keep in close contact with the bottom of the upper blocking plate 301. When the drive shaft 201 moves upward, the first cleaning brush 203 contacts the filter screen 1011, thereby simultaneously rotating with the drive shaft 201 to brush the filter screen 1011.

[0056] Example 3

[0057] Reference Figure 1-17 The difference between this embodiment and embodiment 2 is that a first spur gear 401 and a second spur gear 402 are respectively fixed on the mounting shafts of the two second baffles 4. The first spur gear 401 and the second spur gear 402 mesh with each other. A third spur gear 403 is fixed on the second spur gear 402 and meshes with the vertical rack 3015. The first spur gear 401 and the second spur gear 402 have the same diameter, and the diameter of the third spur gear 403 is larger than the diameter of the second spur gear 402.

[0058] When the air guide frame 3013 descends, the vertical rack 3015 moves downward. The third spur gear 403 meshes with the vertical rack 3015, driving the third spur gear 403 to rotate. Then, the first spur gear 401 meshes with the second spur gear 402, driving the two second baffles 4 to rotate synchronously in opposite directions. Thus, the state can be switched through linkage without the need for additional drive components. The diameter of the third spur gear 403 is larger than that of the second spur gear 402, ensuring that within a large range of vertical rack movement of the vertical rack 3015, only the third spur gear 403 can be rotated by 45 degrees, and each of the two second baffles 4 can be rotated by 45 degrees.

[0059] Example 4

[0060] Reference Figure 1-17The difference between this embodiment and embodiment 3 is that the collection tank 1 is provided with two power transmission boxes 5 inside. A vertical shaft 503 is rotatably installed inside the power transmission box 5. The top end of the vertical shaft 503 in the lower power transmission box 5 is fixed to the rotating ring 6. A polygonal pin 502 is fixed to the top end of the vertical shaft 503 in the upper power transmission box 5. The top end of the polygonal pin 502 extends movably into the groove opened at the bottom end of the drive shaft 201. A power input shaft 501 is rotatably installed on the power transmission box 5. A first bevel gear 505 is fixed to one end of the power input shaft 501, and a second bevel gear 504 is fixed to the bottom end of the vertical shaft 503. The first bevel gear 505 and the second bevel gear 504 mesh. The other end of the power input shaft 501 is fixed to the synchronous pulley 507 through a one-way transmission 506. A synchronous belt 508 is sleeved between the outer sides of the two synchronous pulleys 507. One of the synchronous pulleys 507 is fixed to the output shaft of the rotary motor 509.

[0061] The rotary motor 509 can drive two synchronous pulleys 507 to rotate synchronously in both directions. The one-way transmission device 506 uses a ratchet and ratchet engagement to achieve a one-way transmission effect. The two one-way transmission devices 506 can transmit power in different directions. Therefore, when the rotary motor 509 rotates in both directions, it can drive one power input shaft 501 to rotate. When the lower power input shaft 501 is driven to rotate, the dynamic stopper can be driven to rotate through the meshing of the first bevel gear 505 and the second bevel gear 504. When the upper power input shaft 501 is driven to rotate, the polygonal pin 502 can be driven to rotate, thereby driving the drive shaft 201 to rotate, which in turn drives the first cleaning brush 203, the second cleaning brush 3023, and the third cleaning brush 3022 to perform active cleaning.
