Description

Technical Field

[0001] This invention relates to the field of distillation apparatus technology, specifically to a rapid distillation apparatus and processing technology for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. Background Technology

[0002] Prothioconazole is a broad-spectrum triazole thione fungicide developed by Bayer AG, exhibiting strong antifungal effects. A key intermediate in its synthesis is 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. This intermediate primarily exists in liquid form and requires distillation during production to improve purity and yield. Distillation effectively separates impurities, ensuring the quality of the final product and meeting industrial production requirements.

[0003] Chinese Patent Publication No. CN221788172U discloses a rapid distillation apparatus for 2-chloro-1-(1-chlorocyclopropyl)acetone. The apparatus includes a distillation vessel body, a gas phase outlet, a feed pump, a liquid circulation pipe, and a spray pipe. The gas phase outlet is fixedly connected to the distillation vessel body. The feed pump is fixedly installed on the distillation vessel body and communicates with the interior of the vessel body. The liquid circulation pipe is fixedly connected to both the distillation vessel body and the feed pump. The spray pipe is fixedly connected inside the distillation vessel body. This allows the rapid distillation apparatus to increase the heating area of ​​the liquid through circulating spraying during operation, thereby effectively improving the distillation rate and quality. Simultaneously, it effectively condenses and collects the gas separated during distillation, facilitating steam transport and thus significantly improving the distillation efficiency and practicality of the rapid distillation apparatus.

[0004] However, the current distillation apparatus has the following problems: ethyl ketone will accumulate at the bottom of the distillation apparatus. Although the heating of the feed liquid is increased by circulating spraying, the ethyl ketone that is not completely distilled during the spraying process will accumulate with the ethyl ketone at the bottom of the distillation apparatus, so that the distillation efficiency of the ethyl ketone accumulated at the bottom of the distillation apparatus remains slow. Therefore, we propose a rapid distillation apparatus and process for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rapid distillation apparatus and processing technology for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid distillation apparatus for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, comprising a distillation vessel body, a steam inlet pipe fixedly connected to the lower exterior of the distillation vessel body, a spray device for circulating distillation of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone provided at the top of the distillation vessel body, a steam outlet pipe fixedly connected to the top of the distillation vessel body, a feed inlet fixedly connected to the top of the distillation vessel body, a drain pipe fixedly connected to the bottom of the distillation vessel body, a gas phase outlet fixedly connected to the upper outer wall of the distillation vessel body, and a stratified flow device provided at the top of the distillation vessel body. The stratified flow device includes a motor, the bottom of which is fixedly connected to the top of the distillation vessel body. A rotating shaft is fixedly connected to the motor's output shaft, and two flower-shaped baffles are fixedly connected to the outer wall of the rotating shaft. A vertical Z-shaped rod is fixedly connected to the top of the inner wall of the distillation vessel body, and a first stratification frame is fixedly connected to the bottom of the vertical Z-shaped rod. A first slot is formed at the bottom of the first stratification frame, and a connecting plate is fixedly connected to the bottom of the first stratification frame. A second stratification frame is fixedly connected to the bottom of the connecting plate, and a second slot is formed at the bottom of the second stratification frame. When acetone to be distilled is poured into the distillation vessel body through the feed inlet, the motor is started. The output shaft will cause the rotating shaft to rotate, which will cause the flower-shaped baffle to no longer block the first and second slots. Then the motor will be turned off, and the acetone poured into the distillation vessel will first accumulate in the first layering frame. Then a portion will enter the second layering frame through the first slot, and then a portion in the second layering frame will flow to the bottom of the distillation vessel through the second slot. Then the motor will be started immediately, and the output shaft of the motor will cause the rotating shaft to rotate, which will cause the flower-shaped baffle to block the first and second slots again, so that the acetone stays in the first layering frame, the second layering frame and the bottom of the distillation vessel respectively. Then the motor will be turned off again, and the spray device will be started simultaneously. The motor and spray device spray acetone from the bottom of the distillation vessel into the first layered frame. The acetone in the first layered frame enters the second layered frame through the first slot. A portion of the acetone in the second layered frame flows back to the bottom of the distillation vessel through the second slot, thus forming a dispersed flow. During this flow of acetone, the external steam equipment inputs high-temperature steam into the distillation vessel through the steam inlet pipe, thereby achieving the effect of distilling acetone. During the distillation process, the gas separated from the acetone can be discharged to the external condenser through the gas phase outlet. Finally, after the acetone distillation is completed, the steam is discharged through the steam outlet pipe, and the distillate is discharged through the drain pipe.

[0007] According to the above technical solution, one side of the inner wall of the first slot is set as an incline, and one side of the inner wall of the second slot is set as an incline. Several spacer blocks are fixedly connected to the incline of the first slot and the incline of the second slot. At the same time, the spacer blocks will further divert the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing from the first slot and the second slot.

[0008] According to the above technical solution, the first slot and the second slot are staggered, the size of the flowering part of the two flowering baffles is the same as the size of the first slot and the second slot, and the top of the two flowering baffles is in contact with the bottom of the first layered frame and the second layered frame, respectively.

[0009] According to the above technical solution, an anti-sedimentation device is provided at the bottom of the second layered frame. The anti-sedimentation device includes multiple vertical rods, the tops of which are fixedly connected to the bottom of the second layered frame. A fixing block is fixedly connected to the bottom of each vertical rod. A long rod is fixedly connected to the side of the fixing block. A long plate is rotatably connected to the outer wall of the long rod. A torsion spring is provided between the long plate and the fixing block. A ball is fixedly connected to the bottom of the long plate. Multiple elastic plates are fixedly connected to the lower outer wall of the rotating shaft. The ball is located on the displacement trajectory of the multiple elastic plates. The rotation of the rotating shaft drives the elastic plates to rotate. The rotation of the elastic plates will abut against the ball, causing the ball to drive the long plate to rotate along with the rotation of the elastic plates. Therefore, the long plate will rotate on the outer wall of the long rod, causing the torsion spring to deform. When the rotation of the elastic plate no longer abuts against the ball, the torsion spring will use its own large elastic force to drive the long plate and the ball to reset. This process repeats, causing the long plate to rotate continuously.

[0010] According to the above technical solution, the outer wall of the long plate is provided with several flow channels, and the flow channels can further increase the effect of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing to different places.

[0011] According to the above technical solution, auxiliary devices are provided on the inner walls of both the first and second layered frames. Each auxiliary device includes two fixing rings. The outer wall of one fixing ring is fixedly connected to the inner wall of the first layered frame, and the outer wall of the other fixing ring is fixedly connected to the inner wall of the second layered frame. Several elastic telescopic rods are fixedly connected to the bottom of each fixing ring. An impact ring is fixedly connected to the bottom of each elastic telescopic rod. A support block is fixedly connected to the inner wall of the impact ring. An arc-shaped block is fixedly connected to the bottom of the support block. Several abutment posts are fixedly connected to the outer wall of the rotating shaft. The rotation of the rotating shaft will drive several abutment posts... The contact post rotates, and the rotation of the contact post abuts against the curved surface of the arc-shaped block, thus pushing the arc-shaped block upward. The upward movement of the arc-shaped block causes the support block to move upward, which in turn causes the impact ring to move upward. The upward movement of the impact ring moves away from the bottom of the inner wall of the layered frame (the layered frame is a collective term for the first and second layered frames). At the same time, the upward movement of the impact ring compresses the elastic telescopic rod. When the rotation of the contact post no longer abuts against the curved surface of the arc-shaped block, the elastic telescopic rod will use its elasticity to drive the impact ring, support block, and arc-shaped block to reset. This process repeats, and the reciprocating movement of the impact ring strikes the bottom of the inner wall of the layered frame.

[0012] According to the above technical solution, the outer wall of the abutting column is fixedly connected with a number of arc blocks, and the outer arc surfaces of the arc blocks are all fixedly connected with a number of convex balls.

[0013] According to the above technical solution, the arc surface of the arc block is located on the displacement trajectory of the abutting column, the first layered frame is located on the displacement trajectory of one of the impact rings, the second layered frame is located on the displacement trajectory of the other impact ring, the movement of the abutting column will cause the arc block to rotate, and the movement of the arc block will cause the convex ball to rotate.

[0014] A rapid distillation process for 2-chloro-1-(1-chlorocyclopropyl)acetone includes the following steps;

[0015] S1. When the ethyl ketone to be distilled is poured into the body of the distillation vessel from the feed port, the motor is started. The output shaft of the motor will cause the rotating shaft to rotate. The rotation of the rotating shaft will cause the flower-shaped baffle to no longer block the first slot and the second slot.

[0016] S2. Then turn off the motor. The acetone poured into the body of the distillation vessel will first accumulate inside the first layered frame, and then a portion of it will enter the second layered frame through the first slot. Then a portion of it in the second layered frame will flow to the bottom of the body of the distillation vessel through the second slot.

[0017] S3. Then immediately start the motor. The output shaft of the motor will cause the rotating shaft to rotate. The rotation of the rotating shaft will cause the flower-shaped baffle to cover the first slot and the second slot again, so that acetone stays in the first layer frame, the second layer frame and the bottom of the distillation vessel body respectively. Then turn off the motor again.

[0018] S4. Then, start the spraying device and the motor at the same time. The spraying device will spray the acetone at the bottom of the distillation vessel into the first layered frame. The acetone inside the first layered frame will enter the second layered frame through the first slot. A portion of the acetone in the second layered frame will flow to the bottom of the distillation vessel through the second slot, thus forming a dispersed flow state.

[0019] S5. During the flow of ethyl ketone, high-temperature steam is introduced into the body of the distillation vessel through the steam inlet pipe from an external steam device, thereby achieving the effect of distilling ethyl ketone. During the distillation process, the gas separated from ethyl ketone can be discharged to the external condenser through the gas phase outlet. After the ethyl ketone distillation is completed, the steam is discharged through the steam outlet pipe, and finally the distillate is discharged from the drain pipe.

[0020] This invention provides a rapid distillation apparatus and process for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. It offers the following advantages:

[0021] (1) The present invention, through the cooperation of a motor, a rotating shaft, a flower-shaped baffle, a vertical Z-shaped rod, a first layered frame, a connecting plate, a second layered frame, a first slot, and a second slot, allows 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone inside the first layered frame to enter the second layered frame through the first slot. A portion of the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flows to the bottom of the distillation vessel body through the second slot, thus forming a dispersed flow state, thereby ensuring the rapid distillation of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, the flower-shaped baffle is driven to rotate by the rotating shaft due to the start of the motor, so the flower-shaped baffle will intermittently block the first slot and the second slot. This avoids the situation where 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flows faster than the spray from the first and second openings, making it difficult to achieve a dispersed flow effect. Simultaneously, the cooperation of the first and second openings and the spacer block allows the spacer block to further divert the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing from the first and second openings, thereby further improving the rapid distillation effect of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. Furthermore, the diversion of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone reduces the problem of crystallization during distillation.

[0022] (2) The present invention, through the cooperation of vertical rod, fixed block, long rod, long plate, ball block and elastic plate, makes the reciprocating motion of the long plate prevent 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing from the second slot to the main body of the distillation vessel from falling to the same part at the bottom of the main body of the distillation vessel, thereby further preventing 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone from flowing through the same part and causing the problem of crystal precipitation; at the same time, through the cooperation of the flow channel and the long plate, the flow channel can further increase the effect of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing to different places.

[0023] (3) The present invention uses the combination of a fixed ring, an elastic telescopic rod, an impact ring, a support block, an arc block, and a contact post to make the reciprocating movement of the impact ring strike the bottom of the inner wall of the layered frame, thereby increasing the fluidity of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the layered frame. Therefore, it can avoid the problem of reduced fluidity of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the first layered frame that is far from the first groove and 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the second layered frame that is far from the second groove. At the same time, the combination of the arc block, the convex ball, and the contact post makes the movement of the contact post drive the arc block to rotate, and the movement of the arc block drive the convex ball to rotate. The rotation of the convex ball increases the cross-flow of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Please see Figures 1-8One embodiment of the present invention is a rapid distillation apparatus for 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, comprising a distillation vessel body 1, a steam inlet pipe 2 fixedly connected to the lower exterior of the distillation vessel body 1, the end of the steam inlet pipe 2 away from the distillation vessel body 1 being fixedly connected to an external steam device, and a spray device 3 for circulating distillation of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone being provided on the top of the distillation vessel body 1. The spray device 3 consists of a connecting pipe, an annular pipe, multiple nozzles, and a drive pump. One end of the connecting pipe is fixedly connected to the bottom of the distillation vessel body 1, the outer wall of the annular pipe is fixedly connected to the end of the connecting pipe away from the distillation vessel body 1, the multiple nozzles are fixedly connected to the lower inner wall of the annular pipe, and the drive pump... Installed on the outer wall of the connecting pipe, the drive pump is electrically connected to an external controller. A steam outlet pipe 4 is fixedly connected to the top of the distillation vessel body 1. A feed inlet 5 is fixedly connected to the top of the distillation vessel body 1. A drain pipe 6 is fixedly connected to the bottom of the distillation vessel body 1. A gas phase outlet 10 is fixedly connected to the upper outer wall of the distillation vessel body 1. The end of the gas phase outlet 10 away from the distillation vessel body 1 is fixedly connected to an external condenser. A stratified flow device 7 is installed on the top of the distillation vessel body 1. The stratified flow device 7 includes a motor 71. The bottom of the motor 71 is fixedly connected to the top of the distillation vessel body 1. A rotating shaft 72 is fixedly connected to the output shaft of the motor 71. Two flower-shaped baffles 73 are fixedly connected to the outer wall of the rotating shaft 72. A vertical Z-shaped rod 74 is fixedly connected to the top of the inner wall of the main body 1. A first layered frame 75 is fixedly connected to the bottom of the vertical Z-shaped rod 74. A first slot 78 is opened at the bottom of the first layered frame 75. A connecting plate 76 is fixedly connected to the bottom of the first layered frame 75. A second layered frame 77 is fixedly connected to the bottom of the connecting plate 76. A second slot 79 is opened at the bottom of the second layered frame 77. The first slot 78 and the second slot 79 are staggered. The size of the opening of the two flower-shaped baffles 73 is the same as the size of the first slot 78 and the second slot 79, respectively. The tops of the two flower-shaped baffles 73 are in contact with the bottoms of the first layered frame 75 and the second layered frame 77, respectively. Through the above structure, the first layered frame 75... The 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone inside enters the second layered frame 77 through the first slot 78. A portion of the second layered frame 77 flows to the bottom of the distillation vessel body 1 through the second slot 79, thus forming a dispersed flow state, thereby ensuring the rapid distillation of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, the flower-shaped baffle 73 is driven to rotate by the rotating shaft 72 due to the start of the motor 71. Therefore, the flower-shaped baffle 73 will intermittently block the first slot 78 and the second slot 79, thereby preventing the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone from flowing faster than the spray speed from the first slot 78 and the second slot 79, thus making it difficult to achieve the effect of dispersed flow.

[0035] One side of the inner wall of the first slot 78 is set as an incline, and one side of the inner wall of the second slot 79 is set as an incline. Several spacer blocks 710 are fixedly connected to the incline of the first slot 78 and the incline of the second slot 79. Through the above structure, the spacer blocks 710 will further split the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing from the first slot 78 and the second slot 79, thereby further improving the effect of rapid distillation of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. At the same time, due to the splitting of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, the problem of crystallization of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone during distillation is reduced.

[0036] The bottom of the second layered frame 77 is provided with an anti-precipitation device 8, which includes multiple vertical rods 81. The tops of the multiple vertical rods 81 are fixedly connected to the bottom of the second layered frame 77, and the bottoms of the multiple vertical rods 81 are fixedly connected to a fixing block 82. The side of the fixing block 82 is fixedly connected to a long rod 83, and the outer wall of the long rod 83 is rotatably connected to a long plate 84. A torsion spring is provided between the long plate 84 and the fixing block 82. The bottom of the long plate 84 is fixedly connected to a ball block 85. The lower part of the outer wall of the rotating shaft 72 is fixedly connected to multiple elastic plates 86, and the ball block 85 is located on the displacement trajectory of the multiple elastic plates 86. Through the above structure, the reciprocating motion of the long plate 84 can prevent 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing from the second slot 79 to the distillation vessel body 1 from falling to the same part at the bottom of the distillation vessel body 1. This further prevents 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone from flowing through the same part and causing the formation of crystal precipitates.

[0037] The outer wall of the long plate 84 is provided with several flow channels 87. Through the above structure, the flow channels 87 can further enhance the effect of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing to different places.

[0038] In use, when the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone to be distilled is poured into the body of the distillation vessel 1 through the feed port 5, the motor 71 is started. The output shaft of the motor 71 will cause the rotating shaft 72 to rotate. The rotation of the rotating shaft 72 will cause the flower-shaped baffle 73 to no longer block the first slot 78 and the second slot 79. Then the motor 71 is turned off. The 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone poured into the body of the distillation vessel 1 will first accumulate in the first layering frame 75. Then a portion will enter the second layering frame 77 through the first slot 78. Then a portion in the second layering frame 77 will flow to the bottom of the body of the distillation vessel 1 through the second slot 79. Then the motor 71 is started again immediately. The output shaft of the motor 71 will cause the rotating shaft 72 to rotate. The rotation of the shaft 72 causes the flower-shaped baffle 73 to again block the first slot 78 and the second slot 79, causing 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone to remain in the first layered frame 75, the second layered frame 77, and the bottom of the distillation vessel body 1, respectively. Then, the motor 71 is turned off again, and the spray device 3 and the motor 71 are simultaneously activated. The spray device 3 sprays the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone from the bottom of the distillation vessel body 1 into the first layered frame 75. The 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone inside the first layered frame 75 flows through the first slot 78 into the second layered frame 77. A portion of the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the second layered frame 77 flows through the second slot 79 to the bottom of the distillation vessel body 1, thus forming a... In this dispersed flow state, during the flow of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, high-temperature steam is introduced into the body of the distillation vessel 1 through the steam inlet pipe 2 from an external steam device, thereby achieving the effect of distilling 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. During the distillation process, the gas separated from 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone can be discharged to the external condenser through the gas phase outlet 10. Finally, after the distillation of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone is completed, the steam is discharged through the steam outlet pipe 4, and the distillate is discharged from the drain pipe 6. During the distillation of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, the flower-shaped baffle 73 will be rotated by the shaft 7 due to the start of the motor 71. Driven by rotation, the flower-shaped baffle 73 intermittently blocks the first slot 78 and the second slot 79, thus preventing the flow of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone from the first slot 78 and the second slot 79 from being faster than the spray speed, which would make it difficult to achieve a dispersed flow effect. At the same time, the spacer block 710 further diverts the 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing from the first slot 78 and the second slot 79, thereby further improving the rapid distillation effect of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone. In addition, due to the diversion of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone, the problem of crystallization of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone during the distillation process is reduced.

[0039] The rotation of the shaft 72 drives the elastic plate 86 to rotate. The rotation of the elastic plate 86 will abut against the ball block 85, causing the ball block 85 to drive the long plate 84 to rotate along with the rotation of the elastic plate 86. Therefore, the long plate 84 will rotate on the outer wall of the long rod 83, causing the torsion spring to deform. When the rotation of the elastic plate 86 no longer abuts against the ball block 85, the torsion spring will use its own large elastic force to drive the long plate 84 and the ball block 85 to return to their original positions. This process repeats, causing the long plate 84 to rotate continuously. The reciprocating motion of the long plate 84 prevents 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing from the second slot 79 to the distillation vessel body 1 from falling to the same position at the bottom of the distillation vessel body 1. This further prevents 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone from flowing through the same part, which would cause crystal precipitation. At the same time, the flow channel 87 can further increase the effect of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone flowing to different places.

[0040] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, auxiliary devices 9 are provided on the inner walls of both the first layered frame 75 and the second layered frame 77. Each auxiliary device 9 includes two fixing rings 91. The outer wall of one fixing ring 91 is fixedly connected to the inner wall of the first layered frame 75, and the outer wall of the other fixing ring 91 is fixedly connected to the inner wall of the second layered frame 77. A plurality of elastic telescopic rods 92 are fixedly connected to the bottom of each fixing ring 91. An impact ring 93 is fixedly connected to the bottom of each elastic telescopic rod 92. A support block 94 is fixedly connected to the inner wall of the impact ring 93. An arc-shaped block 95 is fixedly connected to the bottom of the support block 94. A plurality of [unclear text - possibly related to a rotating shaft 72] are fixedly connected to the outer wall of the rotating shaft 72. The arc surface of the abutting column 96 and the arc-shaped block 95 is located on the displacement trajectory of the abutting column 96. The first layered frame 75 is located on the displacement trajectory of one of the impact rings 93, and the second layered frame 77 is located on the displacement trajectory of the other impact ring 93. With the above structure, the reciprocating movement of the impact ring 93 will knock on the bottom of the inner wall of the layered frame, thereby increasing the fluidity of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the layered frame. Therefore, the problem of reduced fluidity of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the first layered frame 75 away from the first slot 78 and 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the second layered frame 77 away from the second slot 79 can be avoided.

[0041] The outer wall of the contact post 96 is fixedly connected with several arc blocks 97, and the outer arc surfaces of the arc blocks 97 are fixedly connected with several convex balls 98. Through the above structure, the movement of the contact post 96 will drive the arc blocks 97 to rotate, and the movement of the arc blocks 97 will drive the convex balls 98 to rotate. The rotation of the convex balls 98 will increase the cross-linking in the flow process of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.

[0042] In use, the rotation of the shaft 72 causes several abutment posts 96 to rotate. The rotation of the abutment posts 96 abuts the arc surface of the arc block 95, thus pushing the arc block 95 upward. The upward movement of the arc block 95 causes the support block 94 to move upward. The upward movement of the support block 94 causes the impact ring 93 to move upward. The upward movement of the impact ring 93 moves it away from the bottom of the inner wall of the layered frame (the layered frame is the collective name for the first layered frame 75 and the second layered frame 77). At the same time, the upward movement of the impact ring 93 compresses the elastic telescopic rod 92. When the rotation of the abutment posts 96 no longer abuts the arc surface of the arc block 95, the elastic telescopic rod 92 will use its own elasticity to drive the impact ring 93 and the support block. 94 and the arc block 95 are reset, and this process is repeated. The reciprocating movement of the impact ring 93 will knock on the bottom of the inner wall of the layered frame, thereby increasing the fluidity of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the layered frame. Therefore, it can avoid the problem of reduced fluidity of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the first layered frame 75 that is far from the first slot 78 and 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone in the second layered frame 77 that is far from the second slot 79. The movement of the contact column 96 will drive the arc block 97 to rotate, and the movement of the arc block 97 will drive the convex ball 98 to rotate. The rotation of the convex ball 98 will increase the cross-flow of 2-chloro-1-(1-chlorocyclopropyl)ethyl ketone.
