Description

Technical Field

[0001] The present invention relates to the technical field of distillation devices, and particularly to a rapid distillation device and processing technology for 2-chloro-1-(1-chlorocyclopropyl)ethanone. Background Art

[0002] Prothioconazole is a broad-spectrum triazolethione fungicide developed by Bayer, with a strong antifungal effect. The key intermediate in its synthesis process is 2-chloro-1-(1-chlorocyclopropyl)ethanone. This intermediate mainly exists in liquid form and needs to be distilled during the production process to improve purity and yield. The distillation process can effectively separate impure substances, ensure the quality of the final product, and meet the requirements of industrial production.

[0003] Chinese Patent with publication number CN221788172U discloses a rapid distillation device for 2-chloro-1-(1-chlorocyclopropyl)ethanone. The ethanone rapid distillation device includes a distillation kettle main body, a gas phase outlet, a feed pump, a liquid material circulation pipe, and a spray pipe. The gas phase outlet is fixedly connected to the distillation kettle main body. The feed pump is fixedly installed on the distillation kettle main body and is communicated with the inside of the distillation kettle main body. The liquid material circulation pipe is fixedly connected to the distillation kettle main body and the feed pump. The spray pipe is fixedly connected inside the distillation kettle main body, enabling the ethanone rapid distillation device to increase the heating area of the liquid material through the way of circulating spraying during use, thereby effectively improving the distillation rate and quality. At the same time, during the distillation process, the gas separated by distillation can be well condensed and collected, and it is also convenient to transport the steam, thus effectively improving the distillation efficiency and practicability of the ethanone rapid distillation device.

[0004] However, the current distillation device has the following problems: The ethanone in this distillation device will accumulate at the bottom of the distillation device. Although the heating of the liquid material is increased through the way of circulating spraying, the ethanone that is not completely distilled during the spraying process will accumulate with the ethanone at the bottom of the distillation device, resulting in a slow distillation efficiency of the ethanone accumulated at the bottom of the distillation device. Therefore, we propose a rapid distillation device and processing technology for 2-chloro-1-(1-chlorocyclopropyl)ethanone. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a rapid distillation device and processing technology for 2-chloro-1-(1-chlorocyclopropyl)ethanone, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A rapid distillation device for 2-chloro-1-(1-chlorocyclopropyl)ethanone, comprising a distillation kettle main body. A steam inlet pipe is fixedly connected to the lower part of the outer side of the distillation kettle main body. A spraying device for circulating and distilling 2-chloro-1-(1-chlorocyclopropyl)ethanone is arranged at the top of the distillation kettle main body. A steam outlet pipe is fixedly connected to the top of the distillation kettle main body. A feed inlet is fixedly connected to the top of the distillation kettle main body. A drain pipe is fixedly connected to the bottom of the distillation kettle main body. A gas phase outlet is fixedly connected to the upper part of the outer wall of the distillation kettle main body. A layered flow device is arranged at the top of the distillation kettle main body. The layered flow device includes a motor. The bottom of the motor is fixedly connected to the top of the distillation kettle main body. The output shaft of the motor is fixedly connected with a rotating shaft. 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 kettle main body. The bottom of the vertical Z-shaped rod is fixedly connected with a first layered frame. A first notch is opened at the bottom of the first layered frame. A connecting plate is fixedly connected to the bottom of the first layered frame. A second layered frame is fixedly connected to the bottom of the connecting plate. A second notch is opened at the bottom of the second layered frame. When pouring the ethanone to be distilled into the distillation kettle main body from the feed inlet, start the motor. The output shaft of the started motor will make the rotating shaft rotate. The rotation of the rotating shaft will drive the flower-shaped baffles to no longer block the first notch and the second notch. Then turn off the motor. The ethanone poured into the distillation kettle main body will first gather inside the first layered frame, and then a part of it will enter the second layered frame through the first notch. Then a part of the ethanone in the second layered frame will flow to the bottom of the distillation kettle main body through the second notch. Then immediately start the motor. The output shaft of the motor will make the rotating shaft rotate. The rotation of the rotating shaft will drive the flower-shaped baffles to block the first notch and the second notch again, so that the ethanone stays in the first layered frame, the second layered frame and the bottom of the distillation kettle main body respectively. Then turn off the motor again. Then start the spraying device and the motor at the same time. The spraying device will spray the ethanone at the bottom of the distillation kettle main body into the first layered frame. The ethanone inside the first layered frame will enter the second layered frame through the first notch. A part of the ethanone in the second layered frame will flow to the bottom of the distillation kettle main body through the second notch, thus forming a state of dispersed flow. During the flow process of the ethanone, an external steam device inputs high-temperature steam into the distillation kettle main body through the steam inlet pipe, so as to achieve the effect of distilling the ethanone. During the distillation process, the gas separated from the ethanone can be discharged to an external condenser through the gas phase outlet. Finally, after the distillation of the ethanone is completed, the steam is discharged through the steam outlet pipe. Finally, the distillate is discharged from the drain pipe.

[0007] According to the above technical solution, one side of the inner wall of the first notch is set to be inclined, one side of the inner wall of the second notch is set to be inclined, and a plurality of spacer blocks are fixedly connected to the inclined surfaces of the first notch and the second notch. At the same time, the spacer blocks will further divide the flow of 2-chloro-1-(1-chlorocyclopropyl)ethanone flowing from the first notch and the second notch.

[0008] According to the above technical solution, the first notch and the second notch are arranged in an interleaved manner. The sizes of the blooming parts of the two blooming baffles are the same as the sizes of the first notch and the second notch respectively. The tops of the two blooming baffles are in contact with the bottoms of the first stratified frame and the second stratified frame respectively.

[0009] According to the above technical solution, a sediment prevention device is provided at the bottom of the second stratified frame. The sediment prevention device includes a plurality of vertical rods. The tops of the plurality of vertical rods are fixedly connected to the bottom of the second stratified frame. The bottoms of the plurality of vertical rods are fixedly connected with fixing blocks. A long rod is fixedly connected to the side surface of the fixing block. A long plate is rotatably connected to the outer wall of the long rod. A torsion spring is arranged between the long plate and the fixing block. A ball block is fixedly connected to the bottom of the long plate. A plurality of elastic plates are fixedly connected to the lower part of the outer wall of the rotating shaft. The ball block is located on the displacement track of the plurality of elastic plates. The rotation of the rotating shaft drives the elastic plates to rotate. The rotation of the elastic plates will contact the ball block, so that the ball block drives 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 and cause the torsion spring to deform. When the rotation of the elastic plates no longer contacts the ball block, the torsion spring will drive the long plate and the ball block to reset through its own large elastic force. This process repeats, so that the long plate keeps rotating back and forth.

[0010] According to the above technical solution, a plurality of flow grooves are formed on the outer wall of the long plate. At the same time, the flow grooves can further enhance the effect of 2-chloro-1-(1-chlorocyclopropyl)ethanone flowing to different places.

[0011] According to the above technical solution, the inner walls of the first layered frame and the second layered frame are both provided with auxiliary devices, and the auxiliary devices include two fixing rings, wherein the outer wall of one of the fixing rings 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, and the bottoms of the two fixing rings are fixedly connected to a plurality of elastic telescopic rods, the bottoms of the elastic telescopic rods are fixedly connected to impact rings, the inner walls of the impact rings are fixedly connected to support blocks, the bottoms of the support blocks are fixedly connected to arc blocks, and the outer wall of the rotating shaft is fixedly connected to a plurality of abutment columns, and the rotation of the rotating shaft will drive a plurality of abutment columns to rotate. The contact column rotates, and the rotation of the resistance column will resist the arc surface of the arc block, thereby pushing the arc block upward, and the upward movement of the arc block will drive the support block to move upward, and the upward movement of the support block will drive the impact ring to move upward, and the upward movement of the impact ring will move away from the bottom of the inner wall of the layered frame (the layered frame is a general term for the first layered frame and the second layered frame). At the same time, the upward movement of the impact ring will squeeze the elastic telescopic rod, and when the rotation of the resistance column does not resist the arc surface of the arc block, the elastic telescopic rod will drive the impact ring, the support block and the arc block to reset through its own elasticity, and so on. The reciprocating movement of the impact ring will knock on the bottom of the inner wall of the layered frame.

[0012] According to the above technical solution, the outer wall of the abutment column is fixedly connected with a plurality of arc blocks, and the outer arc surfaces of the plurality of arc blocks are fixedly connected with a plurality 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 resistance column, the first layered frame is located on the displacement trajectory of one of the impact rings, and the second layered frame is located on the displacement trajectory of the other impact ring. The movement of the resistance column will drive the arc block to rotate, and the movement of the arc block will drive the convex ball to rotate.

[0014] A rapid distillation process for 2-chloro-1-(1-chlorocyclopropyl)ethanone comprises the following steps: S1. When the acetone to be distilled is poured from the feed port into the main body of the distillation kettle, the motor is started. The output shaft of the motor is started to rotate the shaft. The rotation of the shaft drives the flower-shaped baffle to no longer cover the first notch and the second notch; S2, then turn off the motor, pour the acetone into the still body, it will first gather inside the first layer frame, then a part of it will enter the second layer frame through the first notch, and then a part of it in the second layer frame will flow to the bottom of the still body through the second notch; S3, then immediately start the motor, the output shaft of the motor will make the shaft rotate, the rotation of the shaft will drive the flower-shaped baffle to re-cover the first notch and the second notch, so that the acetone stays in the first layer frame, the second layer frame and the bottom of the distillation kettle body, and then close the motor again; S4. Then, start the spraying device and the motor simultaneously. The spraying device will spray the acetone at the bottom of the main body of the distillation kettle into the first stratification frame. The acetone inside the first stratification frame will enter the second stratification frame through the first notch, and a part of the acetone in the second stratification frame will flow to the bottom of the main body of the distillation kettle through the second notch, thus forming a state of dispersed flow.

[0015] S5. During the flow process of the acetone, make the external steam equipment input high-temperature steam into the main body of the distillation kettle through the steam inlet pipe, so as to achieve the effect of distilling the 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 finally the distillate is discharged from the drain pipe.

[0016] The present invention provides a rapid distillation device and processing technology for 2-chloro-1-(1-chlorocyclopropyl)acetone. It has the following beneficial effects: (1) Through the cooperation of the motor, the rotating shaft, the flower-shaped baffle, the vertical Z-shaped rod, the first stratification frame, the connecting plate, the second stratification frame, the first notch, and the second notch, the 2-chloro-1-(1-chlorocyclopropyl)acetone inside the first stratification frame will enter the second stratification frame through the first notch, and a part of the acetone in the second stratification frame will flow to the bottom of the main body of the distillation kettle through the second notch, thus forming a state of dispersed flow, so as to ensure the rapid distillation of 2-chloro-1-(1-chlorocyclopropyl)acetone. At the same time, the flower-shaped baffle will be driven by the rotating shaft to rotate because of the start of the motor. Therefore, the flower-shaped baffle will intermittently block the first notch and the second notch, so as to avoid the flow rate of 2-chloro-1-(1-chlorocyclopropyl)acetone from the first notch and the second notch being faster than the spraying speed, resulting in the difficulty of achieving the effect of dispersed flow. At the same time, through the cooperation of the first notch, the second notch, and the spacer block, the spacer block will further divide the flow of 2-chloro-1-(1-chlorocyclopropyl)acetone from the first notch and the second notch, thus further improving the effect of rapid distillation of 2-chloro-1-(1-chlorocyclopropyl)acetone. At the same time, due to the diversion of 2-chloro-1-(1-chlorocyclopropyl)acetone, the problem of crystallization of 2-chloro-1-(1-chlorocyclopropyl)acetone during the distillation process is reduced.

[0017] (2) Through the cooperation of the vertical rod, fixed block, long rod, long board, spherical block, and elastic board in the present invention, the reciprocation of the long board enables the 2-chloro-1-(1-chlorocyclopropyl)ethanone flowing from the second notch to the main body of the distillation kettle not to always fall onto the same part at the bottom of the main body of the distillation kettle, thereby further preventing the problem that the 2-chloro-1-(1-chlorocyclopropyl)ethanone always flows through the same part and causes the generation of crystal precipitates; meanwhile, through the cooperation of the flow groove and the long board, the flow groove can further enhance the effect of the 2-chloro-1-(1-chlorocyclopropyl)ethanone flowing to different places.

[0018] (3) Through the cooperation of the fixed ring, elastic telescopic rod, impact ring, support block, arc-shaped block, and contact column in the present invention, the reciprocating movement of the impact ring will knock on the inner wall bottom of the stratification frame, thereby increasing the fluidity of the 2-chloro-1-(1-chlorocyclopropyl)ethanone in the stratification frame. Therefore, it can avoid the problem that the fluidity of the 2-chloro-1-(1-chlorocyclopropyl)ethanone far from the first notch in the first stratification frame and the 2-chloro-1-(1-chlorocyclopropyl)ethanone far from the second notch in the second stratification frame decreases; meanwhile, through the cooperation of the arc-shaped block, convex sphere, and contact column, the movement of the contact column will drive the arc-shaped block to rotate, the movement of the arc-shaped block will drive the convex sphere to rotate, and the rotation of the convex sphere will increase the interlacing of the 2-chloro-1-(1-chlorocyclopropyl)ethanone during the flowing process.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figures 1 - 8, an embodiment of the present invention is: a rapid distillation device for 2-chloro-1-(1-chlorocyclopropyl)ethanone, including a distillation kettle main body 1. A steam inlet pipe 2 is fixedly connected to the lower part outside the distillation kettle main body 1. One end of the steam inlet pipe 2 away from the distillation kettle main body 1 is fixedly connected to an external steam device. A spraying device 3 for circulating and distilling 2-chloro-1-(1-chlorocyclopropyl)ethanone is arranged at the top of the distillation kettle main body 1. The spraying device 3 is composed of a connecting pipe, an annular pipe, multiple nozzles, and a driving pump. One end of the connecting pipe is fixedly connected to the bottom of the distillation kettle main body 1. The outer wall of the annular pipe is fixedly connected to the end of the connecting pipe away from the distillation kettle main body 1. Multiple nozzles are fixedly connected to the lower part of the inner wall of the annular pipe. The driving pump is installed on the outer wall of the connecting pipe and is electrically connected to an external controller. A steam outlet pipe 4 is fixedly connected to the top of the distillation kettle main body 1. A feed inlet 5 is fixedly connected to the top of the distillation kettle main body 1. A drain pipe 6 is fixedly connected to the bottom of the distillation kettle main body 1. A gas phase outlet 10 is fixedly connected to the upper part of the outer wall of the distillation kettle main body 1. One end of the gas phase outlet 10 away from the distillation kettle main body 1 is fixedly connected to an external condenser. A layered flow device 7 is arranged at the top of the distillation kettle main body 1. The layered flow device 7 includes a motor 71. The bottom of the motor 71 is fixedly connected to the top of the distillation kettle main body 1. The output shaft of the motor 71 is fixedly connected to a rotating shaft 72. 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 distillation kettle main body 1. The bottom of the vertical Z-shaped rod 74 is fixedly connected to a first layered frame 75. A first notch 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 notch 79 is opened at the bottom of the second layered frame 77. The first notch 78 and the second notch 79 are arranged in a staggered manner. The sizes of the blooming parts of the two flower-shaped baffles 73 are respectively the same as the sizes of the first notch 78 and the second notch 79. The tops of the two flower-shaped baffles 73 are respectively in contact with the bottoms of the first layered frame 75 and the second layered frame 77. Through the setting of the above structure, the 2-chloro-1-(1-chlorocyclopropyl)ethanone inside the first layered frame 75 will enter the second layered frame 77 through the first notch 78, and a part of the 2-chloro-1-(1-chlorocyclopropyl)ethanone in the second layered frame 77 will flow to the bottom of the distillation kettle main body 1 through the second notch 79, thus forming a state of dispersed flow, so as to ensure the rapid distillation of 2-chloro-1-(1-chlorocyclopropyl)ethanone. At the same time, the flower-shaped baffle 73 will be driven by the rotating shaft 72 to rotate due to the start of the motor 71. Therefore, the flower-shaped baffle 73 will intermittently block the first notch 78 and the second notch 79, so as to prevent the 2-chloro-1-(1-chlorocyclopropyl)ethanone from flowing faster than the spraying speed at the first notch 78 and the second notch 79, resulting in the difficulty of achieving the effect of dispersed flow.

[0023] One side of the inner wall of the first notch 78 is set to be inclined, one side of the inner wall of the second notch 79 is set to be inclined, and a plurality of spacer blocks 710 are fixedly connected to the inclined surfaces of both the first notch 78 and the second notch 79. Through the above structure, the spacer blocks 710 will further divide the flow of 2-chloro-1-(1-chlorocyclopropyl)ethanone flowing from the first notch 78 and the second notch 79, thereby further improving the effect of rapid distillation of 2-chloro-1-(1-chlorocyclopropyl)ethanone. At the same time, due to the diversion of 2-chloro-1-(1-chlorocyclopropyl)ethanone, the problem of crystallization of 2-chloro-1-(1-chlorocyclopropyl)ethanone during distillation is reduced.

[0024] A precipitation prevention device 8 is provided at the bottom of the second stratification frame 77. The precipitation prevention device 8 includes a plurality of vertical rods 81. The tops of the plurality of vertical rods 81 are fixedly connected to the bottom of the second stratification frame 77. The bottoms of the plurality of vertical rods 81 are fixedly connected with fixing blocks 82. A long rod 83 is fixedly connected to the side surface of the fixing block 82. A long plate 84 is rotatably connected to the outer wall of the long rod 83. A torsion spring is provided between the long plate 84 and the fixing block 82. A spherical block 85 is fixedly connected to the bottom of the long plate 84. A plurality of elastic plates 86 are fixedly connected to the lower part of the outer wall of the rotating shaft 72. The spherical block 85 is located on the displacement trajectory of the plurality of elastic plates 86. Through the above structure, the reciprocation of the long plate 84 can prevent the 2-chloro-1-(1-chlorocyclopropyl)ethanone flowing from the second notch 79 to the distillation kettle body 1 from always falling to the same part of the bottom of the distillation kettle body 1, thereby further preventing the problem of crystallization precipitates caused by the 2-chloro-1-(1-chlorocyclopropyl)ethanone always flowing through the same part.

[0025] A plurality of flow grooves 87 are formed in the outer wall of the long plate 84. Through the above structure, the flow grooves 87 can further increase the effect of the 2-chloro-1-(1-chlorocyclopropyl)ethanone flowing to different places.

[0026] During use, when pouring 2-chloro-1-(1-chlorocyclopropyl)ethanone to be distilled into the interior of the distillation kettle main body 1 from the feed port 5, start the motor 71. The output shaft of the started motor 71 will cause the rotating shaft 72 to rotate. The rotation of the rotating shaft 72 will drive the blooming-shaped baffle 73 to no longer block the first notch 78 and the second notch 79. Then turn off the motor 71. The 2-chloro-1-(1-chlorocyclopropyl)ethanone poured into the interior of the distillation kettle main body 1 will first gather inside the first stratification frame 75, and then a part will enter the second stratification frame 77 through the first notch 78. Then a part in the second stratification frame 77 will flow to the bottom of the distillation kettle main body 1 through the second notch 79. Then immediately start the motor 71. The output shaft of the motor 71 will cause the rotating shaft 72 to rotate. The rotation of the rotating shaft 72 will drive the blooming-shaped baffle 73 to re-block the first notch 78 and the second notch 79, so that 2-chloro-1-(1-chlorocyclopropyl)ethanone stays in the first stratification frame 75, the second stratification frame 77 and the bottom of the distillation kettle main body 1 respectively. Then turn off the motor 71 again. Then start the spraying device 3 and the motor 71 at the same time. The spraying device 3 will spray the 2-chloro-1-(1-chlorocyclopropyl)ethanone at the bottom of the distillation kettle main body 1 into the interior of the first stratification frame 75. The 2-chloro-1-(1-chlorocyclopropyl)ethanone inside the first stratification frame 75 will enter the second stratification frame 77 through the first notch 78. A part in the second stratification frame 77 will flow to the bottom of the distillation kettle main body 1 through the second notch 79. In this way, a state of dispersed flow is formed. During the flowing process of the 2-chloro-1-(1-chlorocyclopropyl)ethanone, the external steam equipment inputs high-temperature steam into the interior of the distillation kettle main body 1 through the steam inlet pipe 2, so as to achieve the effect of distilling 2-chloro-1-(1-chlorocyclopropyl)ethanone. During the distillation process, the gas separated from 2-chloro-1-(1-chlorocyclopropyl)ethanone can be discharged to the external condenser through the gas phase outlet 10. Finally, after the distillation of 2-chloro-1-(1-chlorocyclopropyl)ethanone is completed, the steam is discharged through the steam outlet pipe 4. Finally, the distillate is discharged from the drain pipe 6. During the distillation process of 2-chloro-1-(1-chlorocyclopropyl)ethanone, the blooming-shaped baffle 73 will be driven by the rotating shaft 72 to rotate due to the start of the motor 71. Therefore, the blooming-shaped baffle 73 will intermittently block the first notch 78 and the second notch 79, so as to prevent the flow rate of 2-chloro-1-(1-chlorocyclopropyl)ethanone from the first notch 78 and the second notch 79 from being faster than the spraying speed, resulting in difficulty in achieving the effect of dispersed flow. At the same time, the spacer block 710 will further divide the flow of 2-chloro-1-(1-chlorocyclopropyl)ethanone flowing from the first notch 78 and the second notch 79, so as to further improve the effect of rapid distillation of 2-chloro-1-(1-chlorocyclopropyl)ethanone. At the same time, due to the diversion of 2-chloro-1-(1-chlorocyclopropyl)ethanone, the problem of crystallization of 2-chloro-1-(1-chlorocyclopropyl)ethanone during the distillation process is reduced.

[0027] The rotation of the rotating shaft 72 drives the elastic plate 86 to rotate, and the rotation of the elastic plate 86 will contact the ball block 85, so that the ball block 85 drives the long plate 84 to rotate following the rotation of the elastic plate 86. Therefore, the long plate 84 will rotate on the outer wall of the long rod 83 and deform the torsion spring. When the rotation of the elastic plate 86 no longer contacts the ball block 85, the torsion spring will drive the long plate 84 and the ball block 85 to reset through its own large elastic force, and so on, so that the long plate 84 keeps reciprocating. The reciprocating of the long plate 84 can prevent the 2-chloro-1-(1-chlorocyclopropyl) ethyl ketone flowing from the second notch 79 to the still body 1 from falling to the same position at the bottom of the still body 1, thereby further preventing the 2-chloro-1-(1-chlorocyclopropyl) ethyl ketone from flowing through the same position all the time, resulting in the problem of crystalline precipitates; at the same time, the flow groove 87 can further increase the effect of the 2-chloro-1-(1-chlorocyclopropyl) ethyl ketone flowing to different places.

Through the setting of 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)ethanone in the layered frame. Therefore, the problem of reduced fluidity of 2-chloro-1-(1-chlorocyclopropyl)ethanone in the first layered frame 75 away from the first notch 78 and 2-chloro-1-(1-chlorocyclopropyl)ethanone in the second layered frame 77 away from the second notch 79 can be avoided.

[0029] The outer wall of the resistance column 96 is fixedly connected with a plurality of arc blocks 97, and the outer arc surfaces of the plurality of arc blocks 97 are fixedly connected with a plurality of convex balls 98. Through the arrangement of the above structure, the movement of the resistance column 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 interlacing of 2-chloro-1-(1-chlorocyclopropyl)ethanone during the flow process.

[0030] When in use, the rotation of the rotating shaft 72 will drive the rotation of several abutment columns 96, wherein the rotation of the abutment columns 96 will abut against the arc surface of the arc block 95, thereby pushing the arc block 95 upward, and the upward movement of the arc block 95 will drive the support block 94 upward, and the upward movement of the support block 94 will drive the impact ring 93 upward, and the upward movement of the impact ring 93 will move away from the bottom of the inner wall of the tiered frame (the tiered frame is the general term for the first tiered frame 75 and the second tiered frame 77). At the same time, the upward movement of the impact ring 93 will squeeze the elastic telescopic rod 92. When the rotation of the abutment column 96 does not abut against the arc surface of the arc block 95, the elastic telescopic rod 92 will drive the impact ring 93 and the support block 94 through its own elasticity. 94 and arc block 95 are reset, and so on and so forth. 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)ethanone in the layered frame, thereby avoiding the problem of reduced fluidity of 2-chloro-1-(1-chlorocyclopropyl)ethanone in the first layered frame 75 away from the first notch 78 and the 2-chloro-1-(1-chlorocyclopropyl)ethanone in the second layered frame 77 away from the second notch 79; the movement of the collision 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, and the rotation of the convex ball 98 will increase the interlacing of 2-chloro-1-(1-chlorocyclopropyl)ethanone during the flow process.
