Description

Technical Field

[0001] The present application relates to the technical field of compound production equipment, and in particular to a hydrogenation reaction device. Background Art

[0002] The hydrogenation reaction unit, also known as a reactor, is a device for preparing compounds. When preparing compounds, liquid raw materials and catalysts need to be added to the reactor, the lid is closed, nitrogen is introduced into the reactor, and the sealing of the reactor is observed. After half an hour, hydrogen is introduced into the reactor multiple times to allow the hydrogen to react with the nitrogen in the reactor, and then hydrogen is continuously introduced. The liquid raw materials, catalysts and hydrogen react at high temperatures. After the reaction is completed, nitrogen is introduced into the reactor to react with the residual hydrogen in the reactor. After cooling, the compounds are taken out of the reactor and the compounds are filtered to obtain the desired products.

[0003] For example, the Chinese patent document with the announcement number CN105727871B discloses a reactor, including a cylinder with an upper head, a sewage outlet at the bottom of the cylinder, a high-pressure pipe extending into the cylinder on the head, and multiple injection holes and injection pipe sections distributed on the high-pressure pipe; the upper end of the high-pressure pipe is arranged on the flange cover and fixed to the side flange of the upper head through the flange cover; a conversion connection valve connected to the high-pressure pipe is arranged on the flange cover. When preparing the compound, the liquid raw material and the catalyst are added to the reactor for reaction, and the compound is taken out after the reaction is completed. Finally, the high-pressure pipe can regularly clean the reactor and clean the residue in the reactor in time, thereby maintaining the cleanliness of the reactor.

[0004] In the above-mentioned related technologies, after the liquid and the catalyst are added into the reactor, nitrogen needs to be added, and hydrogen can be introduced for reaction after a period of time. When nitrogen is introduced for sealing detection, the catalyst in the reactor will fall to the bottom of the reactor under the action of gravity, and even part of the catalyst will enter the discharge pipe, affecting the subsequent reaction of the catalyst and the liquid raw material. Therefore, it is necessary to increase the mixing time to allow the catalyst, hydrogen and liquid raw materials to react completely, thereby reducing the preparation efficiency of the compound. Summary of the invention

[0005] The present application provides a hydrogenation reaction device, aiming to solve the problem of decreased compound preparation efficiency in related technologies.

[0006] A hydrogenation reaction device provided in this application adopts the following technical solution:

[0007] A hydrogenation reaction device comprises a frame and a reactor body arranged on the frame, wherein a stirring assembly for stirring materials is arranged in the reactor body, wherein the stirring assembly comprises a stirring rod rotatably connected to the reactor body and a stirring blade fixed on the stirring rod, wherein a support plate is arranged at the bottom of the reactor body, wherein a collecting assembly for collecting catalysts dropped to the bottom is arranged above the support plate, so that the catalysts are sprinkled to different positions of the liquid materials, wherein a control assembly for driving the collecting assembly to move along the length direction of the stirring rod is arranged on the reactor body; wherein the collecting assembly comprises a collecting plate slidably connected to the stirring rod, a baffle fixed on the collecting plate and a push plate connected to the control assembly, wherein the bottom surface of the push plate abuts against the upper surface of the support plate; wherein a fixing assembly for fixing the push plate on the baffle is arranged on the push plate, wherein when the push plate is fixed on the baffle, the control assembly drives the collecting plate, the baffle and the push plate to move upward, wherein a mounting groove is arranged on the collecting plate, wherein an elastic rubber sheet for sealing the mounting groove is arranged on the collecting plate, and an opening is arranged on the elastic rubber sheet.

[0008] By adopting the above technical solution, when the catalyst is added into the reactor body, the catalyst will fall onto the support plate under the action of gravity, and then the control component drives the push plate to rotate. During the rotation of the push plate, the catalyst that has fallen onto the support plate will be pushed to move toward the baffle. Finally, the catalyst will move to the collecting plate, and the push plate will be fixed to the baffle by the fixing component. At this time, the control component will drive the baffle, the push plate and the collecting plate to move upward. During the movement, they will be subject to the downward impact of the liquid, which will enlarge the opening of the elastic rubber sheet. Then, as the collecting plate moves upward, the material on the collecting plate will sprinkle the catalyst into different heights of the liquid along the length of the stirring rod. At this time, under the action of the stirring blades, the material, the catalyst and the hydrogen can be better mixed, thereby accelerating the reaction speed.

[0009] Optionally, the control assembly includes a control screw rotatably connected to the stirring rod, a control sleeve fixed on the push plate, and a movable block fixed on the baffle, the movable block is slidably connected to the stirring rod, the control sleeve is sleeved on the control screw and threadedly connected to the control screw; a limiting channel is arranged between the lower end surface of the stirring rod and the support plate, the limiting channel is arranged in a circle along the circumference of the stirring rod, and the push plate is provided with an abutment surface for abutting against the top wall of the limiting channel.

[0010] By adopting the above technical solution, when the control screw rotates, it will first drive the control sleeve to rotate, and then under the action of the limiting channel, the control sleeve and the push plate fixed on the control sleeve will rotate synchronously with the control screw, and then the fixing component will fix the push plate on the baffle. At this time, the control screw continues to rotate. Since the push plate is fixed on the baffle and the baffle can only slide along the length direction of the stirring rod, the control screw will drive the collecting plate to move along the length direction of the stirring rod.

[0011] Optionally, the fixing assembly includes a fixing rod fixed on the push plate and a fixing groove opened on the baffle plate, and when the fixing rod is inserted into the fixing groove, the push plate is fixed on the baffle plate.

[0012] By adopting the above technical solution, when the control screw drives the push plate to rotate, the fixed rod will be inserted into the fixed groove, and then the baffle will be fixed on the push plate. When the control screw continues to rotate, it can drive the baffle and the push plate to move along the length direction of the stirring rod at the same time.

[0013] Optionally, a liquid outlet is provided on the support disk, and the liquid outlet and the stirring rod are coaxially arranged. A blocking component is provided on the support disk, and the blocking component is used to block the liquid outlet.

[0014] By adopting the above technical solution, after the catalyst and liquid material are completely reacted, the blocking component no longer blocks the liquid outlet. At this time, the reacted material can enter the bottom of the reactor body from the liquid outlet and finally be discharged through the discharge pipe.

[0015] Optionally, the sealing assembly includes a support rod fixed in the reactor body, a sealing ring sliding on the support rod and a support spring fixed on the support rod, the other end of the support spring abuts against the bottom surface of the sealing ring, the support spring is used to support the sealing ring so that the sealing ring blocks the liquid outlet on the support plate, and the support rod is provided with a pushing assembly for pushing the sealing ring to move upward.

[0016] By adopting the above technical solution, the support spring is used to support the sealing ring so that the sealing ring can seal the liquid outlet on the support plate, and the pushing component pushes the limit ring to move upward, thereby facilitating the opening of the liquid outlet, and finally facilitating the reacted material to enter the bottom of the reactor body through the liquid outlet, and finally to be discharged from the outlet.

[0017] Optionally, the pushing assembly includes a pushing screw fixedly connected to the bottom of the control screw, a pushing ring sleeved on the support rod, and a pushing block passed through the control screw, the pushing block and the pushing screw are threadedly connected, and the pushing block is fixed on the pushing ring, and the diameter of the pushing ring is smaller than the inner diameter of the support spring.

[0018] By adopting the above technical solution, when the control screw rotates, it will drive the pushing screw to rotate, and then the pushing screw drives the pushing block and the pushing ring to move in the direction close to the sealing ring, so that the pushing ring abuts against the sealing ring, and then when the pushing screw continues to rotate, the pushing ring continues to move, and at this time the pushing ring will push the sealing ring upward, thereby facilitating the opening of the liquid outlet.

[0019] Optionally, the pitch of the pushing screw is smaller than the pitch of the controlling screw.

[0020] By adopting the above technical solution, since the pitch of the pushing screw is smaller than the pitch of the controlling screw, when the controlling screw is rotated, the distance moved by the moving block is greater than the distance moved by the pushing block. When the collecting plate moves to a certain height, the pushing block abuts against the sealing ring, and then continues to rotate to enable the pushing ring to push the sealing ring to move upward. At this time, the sealing ring will detach from the supporting spring, and the liquid will enter the bottom of the reactor body through the liquid outlet.

[0021] Optionally, a limit assembly for limiting the position of the collecting plate is provided on the support plate, the limit assembly includes a limit plate slidably connected to the support plate, a limit rod fixed on the limit plate, and a limit spring fixed on the support plate. A limit slot is provided on the support plate, the limit plate and the limit spring are arranged in the limit slot, the limit plate is slidably connected in the limit slot, one end of the limit spring is fixed on the limit plate, and the limit spring is used to pull the limit rod to be inserted into the fixed slot.

[0022] By adopting the above technical solution, when the fixing rod is not inserted into the fixing groove, the limiting rod is in the fixing groove, and the positions of the baffle and the collecting plate can be fixed at this time. During the rotation of the push plate, the push plate drives the fixing rod to rotate at the same time, and then the fixing rod will push the limiting rod in the fixing groove to disengage, and then it is convenient for the collecting plate to move along the length of the stirring rod.

[0023] Optionally, a sealing rubber spring is provided at the opening of the limiting groove, one end of the sealing rubber spring is fixed on the limiting plate, and the other end is fixed on the supporting disk, and the sealing rubber spring is used to seal the opening of the limiting groove.

[0024] By adopting the above technical solution, when the limit spring is stretched, the blocking rubber spring is also stretched, so that when the limit plate moves, the limit groove can still be kept in a blocked state.

[0025] Optionally, the support disk is provided with an inclined surface, which is arranged in a circle along the circumference of the support disk and extends to the sealing ring, so that the upper surface of the sealing ring and the upper surface of the support disk are on the same inclined surface.

[0026] By adopting the above technical solution, under the action of the inclined surface, the center of the sealing ring is at the lowest point, and then the edge of the support plate is the highest, so that when the sealing ring moves upward, it is convenient for the liquid on the support plate to flow to the center position, and then it is convenient to discharge the liquid material in the reactor body.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The control component drives the baffle, push plate and collecting plate to move upward. During the movement, they will be affected by the downward impact of the liquid, which will enlarge the opening of the elastic rubber sheet. Then, as the collecting plate moves upward, the material on the collecting plate will sprinkle the catalyst to different heights of the liquid along the length of the stirring rod.

[0029] 2. Since the pitch of the pushing screw is smaller than the pitch of the controlling screw, when the controlling screw is rotated, the distance moved by the moving block is greater than the distance moved by the pushing block. When the collecting plate moves to a certain height, the pushing block abuts against the blocking ring, and then continues to rotate to enable the pushing ring to push the blocking ring upward.

Figure 1 and Figure 2 A hydrogenation reaction device includes a frame 01 and a reactor body 02 arranged on the frame 01, a stirring assembly 1 for stirring materials is arranged in the reactor body 02, and a feed port and an air inlet are arranged on the reactor body 02, and a discharge port is arranged below the reactor body 02, and the feed port, the air inlet and the discharge port are all provided with control valves; a support plate 04 is arranged at the bottom of the reactor body 02, and the catalyst that sinks to the bottom will fall onto the support plate 04, preventing a part of the catalyst from entering the discharge pipe and avoiding the occurrence of a stirring dead corner, and a collecting assembly 2 is arranged above the support plate 04, and the collecting assembly 2 is used to collect the catalyst that falls to the bottom, and then evenly sprinkle the catalyst to different positions of the liquid material.

[0041] The liquid material is added into the reactor body 02 through the feed port, and then the catalyst is added, and nitrogen is introduced into the reactor. The sealing condition of the reactor is observed. After half an hour, hydrogen is introduced into the reactor several times to make the hydrogen react with the nitrogen in the reactor, and then hydrogen is continuously introduced. The liquid raw material, the catalyst and the hydrogen react at high temperature. After the reaction is completed, nitrogen is introduced into the reactor to react with the residual hydrogen in the reactor. After cooling, the compound is taken out from the reactor, and the compound is filtered to obtain the desired product.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The stirring assembly 1 includes a stirring rod 11 rotatably connected to the reactor body 02 and a stirring blade 12 fixed to the stirring rod 11. The stirring blade 12 is driven to rotate by the stirring rod 11, and then the material in the reactor body 02 can be stirred. At the same time, a control assembly 3 is arranged on the reactor body 02, and the control assembly 3 is used to drive the collecting assembly 2 to move along the length direction of the stirring rod 11.

[0043] Reference Figures 1 to 5 The collecting assembly 2 comprises a collecting plate 21, a baffle 22 and a pushing plate 23. A placing groove 03 is provided on the supporting disk 04. The opening 41 of the placing groove 03 is arranged upward, and the collecting plate 21 is arranged in the placing groove 03. The collecting plate 21 is slidably connected to the stirring rod 11. The baffle 22 is fixed on the collecting plate 21. The pushing plate 23 is arranged on the control assembly 3. The bottom surface of the pushing plate 23 abuts against the upper surface of the supporting disk 04. At the same time, a fixing assembly 5 is provided on the pushing plate 23. The pushing plate 23 is fixed on the baffle 22 by the fixing assembly 5. In the initial state, the control assembly 3 drives the pushing plate 23 to rotate. When the pushing plate 23 is fixed on the baffle 22 by the fixing assembly 5, the control assembly 3 can drive the collecting plate 21, the baffle 22 and the pushing plate 23 to move along the length direction of the stirring rod 11.

[0044] Reference Figures 2 to 5 A mounting groove 42 is provided on the collecting plate 21, and the mounting groove 42 penetrates the collecting plate 21 in a vertical direction. An elastic rubber sheet 43 is provided on the collecting plate 21, and the elastic rubber sheet 43 is used to seal the mounting groove 42. An opening 41 is provided on the elastic rubber sheet 43. When there is no impact force, the size of the opening 41 on the elastic rubber sheet 43 is not large enough for the catalyst to pass through.

[0045] When the catalyst is added into the reactor body 02, the catalyst will fall onto the support plate 04 under the action of gravity, and then the control component 3 drives the push plate 23 to rotate. During the rotation of the push plate 23, the catalyst that has fallen onto the support plate 04 will be pushed to move in the direction close to the baffle 22. Finally, the catalyst will move to the collecting plate 21, and the push plate 23 will be fixed on the baffle 22 by the fixing component 5. At this time, the control component 3 will drive the baffle 22, the push plate 23 and the collecting plate 21 to move upward. During the movement, the elastic rubber sheet 43 is subjected to the downward impact of the liquid, which will enlarge the opening 41 of the elastic rubber sheet 43, and the catalyst will spill out through the opening 41 on the elastic rubber sheet 43. Then, as the collecting plate 21 moves upward, the material on the collecting plate 21 will spill the catalyst to different heights of the liquid along the length of the stirring rod 11. At this time, under the action of the stirring blade 12, the material, the catalyst and the hydrogen can be better mixed, thereby accelerating the reaction speed.

[0046] Reference Figures 3 to 6A liquid outlet 4 is provided on the support plate 04, and the liquid outlet 4 and the stirring rod 11 are coaxially arranged, and a blocking component 6 is provided on the support plate 04, and the blocking component 6 is used to block the liquid outlet 4. After the catalyst and the liquid material are completely reacted, the blocking component 6 no longer blocks the liquid outlet 4. At this time, the reacted material can enter the bottom of the reactor body 02 from the liquid outlet 4, and finally be discharged through the discharge pipe.

[0047] Reference Figures 3 to 6 The fixing assembly 5 includes a fixing rod 51 fixed on the push plate 23 and a fixing groove 52 provided on the baffle plate 22. When the control assembly 3 drives the fixing rod 51 to be inserted into the fixing groove 52 and the control assembly 3 drives the push plate 23 to rotate, the push plate 23 and the collecting plate 21 can slide on the stirring rod 11. In this embodiment, the fixing assembly 5 is provided in two groups. By providing two groups of fixing assemblies 5, the connection effect between the push plate 23 and the baffle plate 22 can be better.

[0048] Reference Figures 3 to 6 The control assembly 3 includes a control screw 31 rotatably connected to the stirring rod 11, a control sleeve 32 fixed on the push plate 23, and a moving block 33 fixed on the baffle 22. At the same time, a moving groove 34 is opened on the stirring rod 11, and the moving block 33 is slidably connected in the moving groove 34. In this embodiment, the moving block 33 is configured as a rectangular block, the control sleeve 32 is sleeved on the control screw 31, and is threadedly connected to the control screw 31. At the same time, the moving block 33 is also sleeved on the control screw 31, and the moving block 33 is slidably connected to the control screw 31.

[0049] Reference Figures 3 to 6 A limiting channel 44 is provided between the lower end surface of the stirring rod 11 and the support plate 04. The limiting channel 44 is provided along the circumference of the stirring rod 11. By providing the limiting channel 44, the lower end surface of the stirring rod 11 and the upper surface of the support plate 04 do not abut. An abutting surface 45 is provided on the push plate 23. The abutting surface 45 is used to abut against the top wall of the limiting channel 44. Then, when the control screw 31 rotates, the control sleeve 32 is first driven to rotate. Then, under the action of the limiting channel 44, the control sleeve 32 The push plate 23 fixed on the control sleeve 32 will rotate synchronously with the control screw 31, and then the fixed rod 51 on the push plate 23 will move into the fixed groove 52. At this time, the control screw 31 continues to rotate. Since the push plate 23 is fixed on the baffle 22, and the baffle 22 can only slide along the length direction of the moving groove 34, the control screw 31 will drive the collecting plate 21 to move, so as to facilitate the catalyst to be sprinkled to different heights of the liquid material. At this time, the reaction speed of the material can be accelerated under the action of the stirring blade 12.

[0050] Reference Figures 3 to 7The sealing component 6 includes a support rod 61 fixed in the reactor body 02, a sealing ring 62 sliding on the support rod 61 and a support spring 63 fixed on the support rod 61, the other end of the support spring 63 abuts against the bottom surface of the sealing ring 62, and the support spring 63 is used to support the sealing ring 62 so that the sealing ring 62 blocks the liquid outlet 4 on the support plate 04, and then a pushing component 7 is arranged on the support rod 61, and the pushing component 7 is used to push the sealing ring 62 to move upward, and then facilitate the opening of the liquid outlet 4, and finally facilitate the reacted material to enter the bottom of the reactor body 02 through the liquid outlet 4, and finally facilitate discharge from the discharge port.

[0051] Reference Figure 5 to Figure 6 The pushing assembly 7 includes a pushing screw 71 fixedly connected to the bottom of the control screw 31, a pushing ring 72 sleeved on the support rod 61, and a pushing block 73 penetrated on the control screw 31. The pushing block 73 is threadedly connected to the pushing screw 71, and the pushing block 73 is fixed on the pushing ring 72. The diameter of the pushing ring 72 is smaller than the inner diameter of the support spring 63. When the control screw 31 rotates, the pushing screw 71 will be driven to rotate, and then the pushing screw 71 will drive the pushing block 73 and the pushing ring 72 to move in the direction close to the blocking ring 62, so that the pushing ring 72 abuts against the blocking ring 62, and then when the pushing screw 71 continues to rotate, the pushing ring 72 continues to move. At this time, the pushing ring 72 will push the blocking ring 62 to move upward, and then it is convenient for the liquid outlet 4 to open.

[0052] In this embodiment, the pitch of the push screw 71 is smaller than the pitch of the control screw 31. Since the pitch of the push screw 71 is smaller than the pitch of the control screw 31, when the control screw 31 is rotated, the distance moved by the moving block 33 is greater than the distance moved by the push block 73. When the collecting plate 21 moves out of the liquid surface, the push block 73 abuts against the blocking ring 62, and then the push ring 72 pushes the blocking ring 62 to move upward only when it continues to rotate. At this time, the blocking ring 62 will be separated from the support spring 63, and the liquid will enter the bottom of the reactor body 02 through the liquid outlet 4. After the reacted liquid is discharged, the control screw 31 is rotated in the reverse direction, and then the push block 73 moves in the reverse direction. Under the action of gravity, the blocking ring 62 moves in the direction close to the support spring 63, and finally abuts against the support spring 63, and the liquid outlet 4 continues to be blocked, and then the collecting plate 21 moves into the mounting groove 42.

[0053] Reference Figure 5 and Figure 8, a limiting assembly 8 is provided on the support plate 04, and the limiting assembly 8 is used to limit the position of the collecting plate 21, and then when the push plate 23 rotates, the collecting plate 21 can be made more stable. The limiting assembly 8 includes a limiting plate 81 slidably connected to the support plate 04, a limiting rod 82 fixed on the limiting plate 81, and a limiting spring 83 fixed on the support plate 04; a limiting groove 46 is provided on the support plate 04, the limiting plate 81 and the limiting spring 83 are arranged in the limiting groove 46, and the limiting plate 81 is slidably connected in the limiting groove 46, one end of the limiting spring 83 is fixed on the limiting plate 81, and the limiting spring 83 is used to push the limiting rod 82 to be inserted into the fixing groove 52, when the fixing rod 51 is not inserted into the fixing groove 52, the limiting rod 82 is in the fixing groove 52, and at this time, the position of the baffle 22 and the collecting plate 21 can be fixed. During the rotation of the push plate 23, the push plate 23 drives the fixing rod 51 to rotate at the same time, and then the fixing rod 51 will push the limiting rod 82 in the fixing slot 52 to disengage, and the fixing rod 51 moves into the fixing slot 52, at which time the limiting spring 83 is in a stretched state. In addition, a blocking rubber spring 47 is provided at the opening 41 of the limiting slot 46, one end of the blocking rubber spring 47 is fixed on the limiting plate 81, and the other end is fixed on the supporting plate 04, and the blocking rubber spring 47 is used to block the opening 41 of the limiting slot 46. When the limiting spring 83 is stretched, the blocking rubber spring 47 is also stretched, so that when the limiting plate 81 moves, the limiting slot 46 can still be in a blocked state.

[0054] Reference Figure 5 and Figure 8 When the control screw 31 drives the collecting plate 21 and the push plate 23 to move upward, the fixed groove 52 and the limit rod 82 are misaligned, and then the limit spring 83 will push the limit rod 82 to move in the opposite direction. When the control screw 31 drives the collecting plate 21 to move in the opposite direction, the collecting plate 21 will push the limit rod 82 to move. At this time, the limit spring 83 continues to be stretched. After the collecting plate 21 is reset, the limit rod 82 corresponds to the fixed groove 52, and then the push plate 23 rotates in the opposite direction. The push plate 23 drives the fixed rod 51 to disengage from the fixed groove 52, and the limit spring 83 will push the limit rod 82 to move into the fixed groove 52, and continue to fix the position of the collecting plate 21, so as to facilitate the subsequent preparation of compounds.

[0055] In order to facilitate the collection plate 21 to move in the opposite direction, the collection plate 21 can push the limit rod 82 and the limit plate 81 to move in the opposite direction. A pushing surface 48 is provided on the limit rod 82, and the pushing surface 48 is used to abut against the bottom surface of the collection plate 21. At this time, when the collection plate 21 is reset, it can push the limit rod 82 to move in the opposite direction.

[0056] Reference Figure 2 and Figure 3, a slope 49 is provided on the support plate 04, and the slope 49 is arranged along the circumference of the support plate 04, and the slope 49 extends to the blocking ring 62, so that the upper surface of the blocking ring 62 and the upper surface of the support plate 04 are on the same slope 49, and finally it is convenient for the push plate 23 to push the catalyst to move above the collecting plate 21. Under the action of the slope 49, the blocking ring 62 is at the lowest point, and then the edge of the support plate 04 is the highest, so that when the blocking ring 62 moves upward, it is convenient for the liquid on the support plate 04 to flow to the center position, and then it is convenient to discharge the liquid material in the reactor body 02.

[0057] Reference Figure 1 and Figure 2 A driving assembly 9 is provided on the reactor body 02, and the driving assembly 9 is used to drive the stirring rod 11 and the control screw 31 to rotate. The driving assembly 9 includes a driving motor 91 fixed on the frame 01, a driving gear 92 fixed on the driving motor 91, and a driven gear 93 fixed on the stirring rod 11, and the driving gear 92 and the driven gear 93 are meshed; a mounting plate 94 is fixed on the stirring rod 11, and a control motor 95 is provided on the mounting plate 94. The control motor 95 is connected to the control screw 31, and the control screw 31 is driven to rotate by the control motor 95.

[0058] The implementation principle of a hydrogenation reaction device in an embodiment of the present application is as follows: when preparing a compound, the catalyst added to the reactor body 02 will fall onto the support plate 04. After the sealing test, hydrogen is introduced into the reactor. At this time, the control screw 31 drives the push plate 23 to rotate. The push plate 23 pushes the catalyst on the support plate 04 to move to the collecting plate 21. Then, when the fixing rod 51 moves into the fixing groove 52, the control screw 31 continues to rotate, which will drive the collecting plate 21 to move upward. During the movement, under the impact of the liquid material, the opening 41 of the elastic rubber sheet 43 will become larger. At this time, the catalyst will be sprinkled into the liquid along the height of the reactor body 02. At this time, the liquid material and the catalyst are stirred by the stirring blade 12. Since the catalyst can be sprinkled at different heights of the liquid, the preparation speed of the compound can be increased.
