Description

Technical Field

[0001] This invention relates to a floating stirred reactor. Background Technology

[0002] Reactors are commonly used reaction equipment in industries such as chemical, pharmaceutical, and food processing, primarily for processes such as mixing, reacting, and dissolving materials. Existing conventional reactors mostly feature fixed stirring structures, meaning the stirring height cannot adaptively adjust to the liquid level inside the reactor. During material mixing, low-level stirring easily leads to uneven mixing and insufficient material mixing at the liquid surface. Furthermore, the cleaning functions of traditional reactors are relatively limited, mostly relying on manual rinsing or fixed spray structures. This results in many blind spots for cleaning the inner walls and the conical accumulation area at the bottom of the reactor, leading to incomplete cleaning. Additionally, the stirring and cleaning structures are independent of each other, resulting in low equipment integration and cumbersome operation.

[0003] Therefore, there is an urgent need to design a reaction vessel with adaptive floating stirring and full-area automatic cleaning function. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a floating stirring reactor with adaptive floating stirring and full-area automatic cleaning function.

[0005] To solve the above problems, the present invention adopts the following technical solution: A floating stirred reactor includes a reactor body and a reactor cover detachably mounted on the top of the reactor body. The bottom of the reactor body has a conical material collection section, and a discharge pipe is located at the bottom axis of the material collection section. A feeding pipe is located near the top of the side of the reactor body, and a light-transmitting plate for observing the liquid level is located on the outer wall of the feeding pipe. The reactor body also includes a floating stirring mechanism, which is slidably mounted on the reactor body. A drive device for rotating the floating stirring mechanism is mounted on the top of the reactor cover. A pressing device for actively pressing down the floating stirring mechanism is also located on the top of the reactor cover. An annular water pipe is located on the top of the reactor cover, with a connecting pipe on the outside of the water pipe. Multiple spray nozzles for spraying the floating stirring mechanism are located at the bottom of the water pipe. An overflow valve is installed at the upper part of the side of the reactor body.

[0006] Preferably, the floating stirring mechanism includes a float, a drive plate, a drive rod, a cleaning device, and a stirring unit. The drive plate is arranged parallel above the float. The lower end of the drive rod is coaxially fixed to the drive plate, and the upper end of the drive rod passes through the lid and cooperates with the drive device and the pressing device. Multiple mounting brackets are arranged in a ring around the outer wall of the float. The mounting brackets are hollow inside. A platform plate is provided at the top of the mounting bracket away from the float. Side support plates corresponding to the mounting brackets are arranged in a ring around the outer wall of the drive plate. The cleaning device is installed between the platform plate and the side support plates. A guide rod is fixedly installed on the platform plate, and the guide rod passes upward through the side support plates and is then installed... A limit cap is installed, and a spring is sleeved on the guide rod. The spring acts between the platform plate and the side support plate. When the drive rod is pressed down against the buoyancy of the liquid by the pressing device, the spring is compressed, causing the cleaning device to be pushed outward and act on the inner wall of the vessel. The driving device then provides driving force, causing the cleaning device to rotate along the inner wall of the vessel to clean the outer wall of the vessel. The stirring unit is installed inside the mounting bracket with an adjustable angle. When the float sinks to the limit position, the stirring unit passively contacts the material gathering part and is retracted to the inner side of the mounting bracket. When the drive plate actively moves down, it presses the stirring unit, causing the stirring unit to be retracted into the mounting bracket.

[0007] Preferably, the cleaning device includes a carrier plate, an upper connecting rod, a lower connecting rod, a pin, and a cleaning part. The carrier plate is vertically arranged, and its length is greater than the distance between the platform plate and the side support plate. The cleaning part is detachably installed on the end of the carrier plate facing the inner wall of the vessel. A pin seat is provided on the end of the carrier plate away from the inner wall of the vessel. A first pin seat is provided at the bottom of the side support plate, and a second pin seat is provided at the top of the platform plate. One end of the upper connecting rod is rotatably connected to the pin seat via a pin, and the other end is connected to the first pin seat via a first pin. One end of the lower connecting rod is rotatably connected to the pin seat via a pin, and the other end is connected to the second pin seat via a second pin. When the drive plate is not pressed down, the spring is in an uncompressed state, and the angle between the upper and lower connecting rods is open, allowing the cleaning part to detach from the inner wall of the vessel. When the drive plate is pressed down, the spring is compressed, reducing the angle between the upper and lower connecting rods, and the cleaning part is pushed out to act on the inner wall of the vessel.

[0008] Preferably, the stirring unit includes a stirring plate, a first spring, a third pin, and clamping plates. Two clamping plates are provided, and the stirring plate is fixedly clamped between the two clamping plates. The third pin is fixed to the inner side of the mounting bracket near the top position, passing through both clamping plates. The clamping plates rotate along the third pin. A first mounting shaft is fixed between the two clamping plates, and a second mounting shaft is provided on the inner side of the mounting bracket. The first spring is installed between the first and second mounting shafts, and a passage is formed between the tops of the two clamping plates. A guide wheel is rotatably mounted on the bearing, and a wheel seat is mounted on the bottom of the side support plate. The bottom of the wheel seat is provided with a wheel groove that matches the guide wheel. A stop block is provided at the end of the wheel groove near the axis of the drive plate. When the drive plate is not pressed down, the first spring is in a tightened state. At this time, the clamping plate is rotated along the third pin, so that the stirring plate rotates to the outside of the mounting bracket for stirring the reacting solution. When the float sinks to the limit position, the end of the stirring plate contacts the inner wall of the aggregate part and then rotates along the third pin, and is pressed into the inside of the mounting bracket.

[0009] Preferably, a cleaning strip is embedded at the bottom of the mounting bracket. When there is a solution in the vessel, the drive plate is actively pressed down, and the wheel seat presses down the guide wheel, so that the stirring plate is retracted into the mounting bracket. When the float is pressed down to the inner bottom of the vessel, the inner wall of the aggregate section is cleaned by the cleaning strip.

[0010] Preferably, the top of the float is provided with an adjustment hole, and a plug is detachably installed in the adjustment hole. Liquid is injected through the adjustment hole to change the internal volume of the float, thereby adjusting its suspension height.

[0011] Preferably, a dispersion cone is provided on the inner inclined surface of the stirring plate. The dispersion cone is conical in shape, and its diameter gradually decreases in the direction away from the stirring plate.

[0012] Preferably, the driving device includes a driving tube, a gear transmission mechanism, and a servo reduction motor. The driving tube is rotatably mounted on the axis of the vessel lid via a bearing. The servo reduction motor is driven by the driving tube via the gear transmission mechanism. A guide bar is axially provided on the inner wall of the driving tube, and a guide groove is provided on the outer wall of the driving rod. The guide bar fits into the guide groove, and the driving rod slides along the axial direction of the driving rod to adapt to changes in the height of the float.

[0013] Preferably, the pressing device includes a hydraulic push rod and a gantry frame. The hydraulic push rod is fixed to the top of the vessel lid by the gantry frame. The movable end of the hydraulic push rod is coaxial with the drive rod. After the movable end of the hydraulic push rod moves down, it pushes the drive rod down.

[0014] Preferably, a pressure plate is installed on the movable end of the hydraulic push rod, and the movable end of the hydraulic push rod and the pressure plate are rotatably coupled through a bearing. The bottom of the pressure plate is provided with a positioning hole for positioning the drive rod.

[0015] The beneficial effects of this invention are: 1. The present invention is equipped with an adaptive floating stirring mechanism. The floating body provides buoyancy and can automatically rise and fall with the liquid level in the vessel, realizing full-area stirring from bottom to top. This solves the problems of fixed stirring depth and uneven stirring at high and low liquid levels in traditional fixed stirring structures, and greatly improves the uniformity of material mixing and reaction efficiency.

[0016] 2. This invention integrates stirring and automatic cleaning functions. Through the cooperation of the pressing device, spring, and connecting rod structure, the cleaning device can be switched between extension and retraction. In the stirring state, the cleaning device retracts without affecting the normal stirring of materials. In the cleaning state, the cleaning device is attached to the inner wall of the vessel and rotates to achieve full-area wiping and cleaning of the inner wall. At the same time, the bottom cleaning strip can target the material accumulation area to completely eliminate cleaning dead corners.

[0017] 3. The stirring unit of the present invention has an adaptive retraction function. When the float sinks to the bottom or the drive plate is pressed down, the stirring unit can automatically retract to the inside of the mounting bracket, avoiding collision and wear between the stirring structure and the vessel body and the material gathering part, while ensuring smooth bottom cleaning operations and higher equipment operating stability.

[0018] 4. The present invention features an adjustable buoyancy floating structure, which can adjust the floating height according to different material liquid levels and densities to adapt to different working conditions; the dispersion cone on the stirring plate can improve the dispersion and stirring effect of materials containing solid particles, making it more functional.

[0027] See Figure 1 and Figure 2 The illustrated floating stirred reactor includes a vessel body 1 and a vessel cover 2 detachably mounted on the top of the vessel body 1. A conical material-gathering section 11 is provided at the bottom of the vessel body 1, and a discharge pipe 12 is provided at the bottom axis of the material-gathering section 11. A discharge valve is installed at the discharge pipe 12. A feeding pipe 13 is provided on the side of the vessel body 1 near the top, and a light-transmitting plate 131 for observing the liquid level is provided on the outer wall of the feeding pipe 13. The reactor also includes a floating stirring mechanism 3, which is slidably mounted on the upper and lower sides. The floating stirring mechanism 3 is rotated and is installed inside the vessel body 1. A driving device 4 is installed on the top of the vessel cover 2 to drive the floating stirring mechanism 3 to rotate. A pressing device 5 is also provided on the top of the vessel cover 2 to actively press down the floating stirring mechanism 3. An annular water pipe 221 is provided on the top of the vessel cover 2. A connecting pipe 222 is provided on the outside of the water pipe 221. Multiple spray nozzles 223 for spraying the floating stirring mechanism 3 are provided at the bottom of the water pipe 221. An overflow valve 181 is installed at the upper part of the side of the vessel body 1.

[0028] This device is used for atmospheric pressure reaction. The connecting pipe 222 is used to connect to the booster pump through the high-pressure hose. When cleaning the inside of the vessel 1, the booster pump pumps water, which is sprayed out through the nozzle 223 to spray and inject water into the inside of the vessel 1 until the water overflows the floating stirring mechanism 3.

[0029] The upper end of the feeding pipe 13 is higher than the height of the kettle cover 2. The water level is observed through the light-transmitting plate 131. During conventional mixing reactions, the liquid level needs to be lower than the height of the kettle cover 2.

[0030] The overflow valve 181 is in the open state during the mixing reaction. The height of the lower scale position of the light-transmitting plate 131 is lower than the height of the overflow valve 181. The liquid injection stops when the liquid level is observed to reach the lower scale position of the light-transmitting plate 131.

[0031] During the cleaning operation, the overflow valve 181 is closed, and the cleaning water is stopped once the vessel body 1 is filled. Then, the interior of the vessel body 1 is cleaned by the rotation of the floating stirring mechanism 3. During the cleaning process, the floating stirring mechanism 3 is gradually pressed down into the water by the pressing device 5. During the pressing process, the driving device 4 provides driving force and rotates slowly.

[0032] Alternatively, the height can be lowered step by step, that is, the floating stirring mechanism 3 can be moved by pressing down the pressing device 5 by moving it one stroke (this stroke is the vertical height that the floating stirring mechanism 3 can clean). After pressing down, the floating stirring mechanism 3 is driven to rotate by the driving device 4. After the rotation is completed, the pressing device 5 continues to press down.

[0033] When the pressing device 5 descends to its limit position, the floating stirring mechanism 3 cleans the inner wall surface of the material gathering section 11.

[0034] Both the pressing device 5 and the driving device 4 are controlled by a controller. By programming the controller, two working modes can be set: one is a stirring and mixing mode, which sets the rotation speed of the driving device 4; the other is a cleaning mode, which sets the pressing speed of the pressing device 5 and adjusts the rotation speed of the driving device 4.

[0035] See Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the floating stirring mechanism 3 includes a float 31, a drive plate 32, a drive rod 33, a cleaning device 34, and a stirring unit 35. The drive plate 32 is arranged parallel above the float 31. The lower end of the drive rod 33 is coaxially fixed with the drive plate 32, and the upper end of the drive rod 33 passes through the lid 2 and cooperates with the drive device 4 and the pressing device 5. Multiple mounting brackets 310 are arranged in a ring around the outer wall of the float 31. The interior of each mounting bracket 310 is hollow. A platform plate 311 is arranged at the top of the mounting bracket 310 away from the float 31. Side support plates 320 corresponding to the mounting brackets 310 are arranged in a ring around the outer wall of the drive plate 32. The cleaning device 34 is installed between the platform plate 311 and the side support plates 320. A guide rod 312 is fixedly arranged on the platform plate 311 and passes upward through the side support plates 320. A limit cap 313 is installed behind the plate 320. A spring 314 is sleeved on the guide rod 312. The spring 314 acts between the platform plate 311 and the side support plate 320. When the drive rod 33 is pressed down against the buoyancy of the liquid by the pressing device 5, the spring 314 is compressed, so that the cleaning device 34 is pushed outward and acts on the inner wall of the vessel 1. Then, the drive device 4 provides driving force, so that the cleaning device 34 rotates along the inner wall of the vessel 1 to clean the outer wall of the vessel 1. The stirring unit 35 is installed inside the mounting bracket 310 with adjustable angle. When the float 31 sinks to the limit position, the stirring unit 35 passively contacts the material gathering part 11 and is retracted to the inside of the mounting bracket 310. When the drive plate 32 moves down actively, it presses the stirring unit 35, so that the stirring unit 35 is retracted into the mounting bracket 310.

[0036] In the above technical solution, the buoyancy is provided by the float 31, so that the floating stirring mechanism 3 is suspended on the liquid surface when it is not subjected to the downward pressure applied by the downward pressure device 5, and the reaction liquid is mixed by the stirring unit 35.

[0037] When no liquid is injected into the vessel body 1, the floating stirring mechanism 3 is located at the bottom of the vessel body 1. As liquid is gradually injected, the floating stirring mechanism 3 gradually floats upward. During the suspension process, the floating stirring mechanism 3 is driven to rotate by the driving device 4, so that the stirring depth gradually increases from bottom to top until the liquid injection is completed.

[0038] The stirring unit 35 is configured to be elastically movable, so that when the float 1 sinks to its limit position, the stirring unit 35 can be retracted into the mounting bracket 310.

[0039] The cleaning device 34 is in a retracted state when the pressing device 5 is not pressed down, and the floating stirring mechanism 3 stirs the liquid.

[0040] When cleaning is required, water is injected into the inside of the vessel 1 and pressed down by the pressing device 5, causing the cleaning device 34 to be pushed outward and thus act on the inner wall of the vessel 1. At this time, the rotational resistance of the floating stirring mechanism 3 increases slightly, and the inner wall of the vessel 1 is effectively cleaned by the rotation of the floating stirring mechanism 3.

[0041] See Figure 3 and Figure 7 As shown, the cleaning device 34 includes a carrier plate 341, an upper connecting rod 342, a lower connecting rod 343, a pin 344, and a cleaning part 345. The carrier plate 341 is vertically arranged, and its length is greater than the distance between the platform plate 311 and the side support plate 320. The cleaning part 345 is detachably installed on the end of the carrier plate 341 facing the inner wall of the vessel body 1. A pin seat 346 is provided on the end of the carrier plate 341 away from the inner wall of the vessel body 1. A first pin seat 3201 is provided at the bottom of the side support plate 320, and a second pin seat 3110 is provided at the top of the platform plate 311. One end of the upper connecting rod 342 is connected to the pin seat 344 via the pin 344. 6. A rotatable connection is made, with a first pin 3202 installed between the other end and the first pin seat 3201. One end of the lower connecting rod 343 is rotatably connected to the pin seat 346 via a pin 344, and the other end is installed with a second pin 3111 between the second pin seat 3110. When the drive plate 32 is not pressed down, the spring 314 is in an uncompressed state. At this time, the angle between the upper connecting rod 342 and the lower connecting rod 343 is open, allowing the cleaning part 345 to detach from the inner wall of the vessel body 1. When the drive plate 32 is pressed down, the spring 314 is compressed, causing the included angle between the upper connecting rod 342 and the lower connecting rod 343 to decrease, and the cleaning part 345 is pushed out to act on the inner wall of the vessel body 1.

[0042] In the above technical solution, the length of the carrier plate 341 is greater than the distance between the platform plate 311 and the side support plate 320, so that when the carrier plate 341 retracts, it is blocked outside the platform plate 311 and the side support plate 320 and remains in a nearly vertical state.

[0043] When the drive plate 32 is pressed down, the angle between the upper connecting rod 342 and the lower connecting rod 343 is reduced, causing the carrier plate 341 to be pushed outward. It acts on the inner wall of the vessel body 1 through the cleaning part 345. With the rotational force applied by the drive device 4, the inner wall of the vessel body 1 is cleaned through the cleaning part 345.

[0044] The cleaning section 345 is selected according to the actual working conditions, and usually uses a soft rubber scraper or cleaning sponge.

[0045] Specifically, an adaptive selection can also be made based on the solution being reacted.

[0046] See Figure 3 , Figure 4 and Figure 8 As shown, the stirring unit 35 includes a stirring plate 351, a first spring 352, a third pin 353, and a clamping plate 354. Two clamping plates 354 are provided. The stirring plate 351 is fixedly clamped between the two clamping plates 354. The third pin 353 is fixed to the inner side of the mounting bracket 310 near the top. The third pin 353 passes through both clamping plates 354, and the clamping plates 354 rotate along the third pin 353. A first mounting shaft 355 is fixedly provided between the two clamping plates 354, and a second mounting shaft 3101 is provided on the inner side of the mounting bracket 310. The first spring 352 is installed between the first mounting shaft 355 and the second mounting shaft 3101, at the top of the two clamping plates 354. A guide wheel 356 is rotatably mounted between the two sides via a bearing. A wheel seat 3202 is mounted on the bottom of the side support plate 320. The bottom of the wheel seat 3202 is provided with a wheel groove 3203 that matches the guide wheel 356. A stop block 3204 is provided at the end of the wheel groove 3203 near the axis of the drive plate 32. When the drive plate 32 is not pressed down, the first spring 352 is in a tightened state. At this time, the clamping plate 354 is rotated along the third pin 353, so that the stirring plate 351 rotates to the outside of the mounting bracket 310 for stirring the reacting solution. When the float 31 sinks to the limit position, the end of the stirring plate 351 contacts the inner wall of the aggregate part 11 and rotates along the third pin 353, and is pressed into the inside of the mounting bracket 310.

[0047] See Figure 3 As shown, a cleaning strip 3102 is embedded at the bottom of the mounting bracket 310. When there is a solution in the vessel 1, the drive plate 32 is actively pressed down. At this time, the wheel seat 3202 presses down the guide wheel 356, so that the stirring plate 351 is retracted into the mounting bracket 310. Until the float 31 is pressed down to the inner bottom of the vessel 1, the inner wall of the aggregate section 11 is cleaned by the cleaning strip 3012.

[0048] In the above technical solution, an angle-adjustable stirring unit 35 is used. When the driving plate 32 is pressed down, the stirring unit 35 is retracted into the inner side of the mounting bracket 310 after being pressed down, so that when the float 31 is pressed down to the limit position, the inner wall surface of the material gathering part 11 can be cleaned by the cleaning strip 3102.

[0049] The cleaning strip 3012 is made of rubber.

[0050] See Figure 9 As shown, the top of the float 31 is provided with an adjustment hole 3111, and a plug 3112 is detachably installed in the adjustment hole 3111. Liquid is injected through the adjustment hole 3111 to change the internal volume of the float 31, thereby adjusting its suspension height.

[0051] This technical solution allows for adjustment of the buoyancy of the float 31.

[0052] See Figure 3 and Figure 8 As shown, a dispersion cone 3551 is provided on the inner inclined surface of the stirring plate 351. The dispersion cone 3551 is conical, and its diameter gradually decreases in the direction away from the stirring plate 351.

[0053] The dispersing cone 3551 is located on the inner inclined surface of the stirring plate 351, so that when the stirring plate 351 touches the agglomeration section 11, the dispersing cone 3551 will not scratch the agglomeration section 11.

[0054] When the stirring plate 351 rotates, the spiked dispersion cone 3551 can improve the dispersion effect on the solution, especially when the solution contains solid particulate matter.

[0055] See Figure 2 , Figure 10 and Figure 11 As shown, the driving device 4 includes a driving tube 41, a gear transmission mechanism 42, and a servo reduction motor 43. The driving tube 41 is rotatably mounted on the axis of the vessel cover 2 via a bearing. The servo reduction motor 43 is driven by the driving tube 41 via the gear transmission mechanism 42. A guide bar 411 is axially arranged on the inner wall of the driving tube 41. A guide groove 331 is provided on the outer wall of the driving rod 33. The guide bar 411 fits into the guide groove 331. The driving rod 33 slides along the axial direction of the driving rod 41 to adapt to the height change of the float 31.

[0056] See Figure 2 As shown, the pressing device 5 includes a hydraulic push rod 51 and a gantry frame 52. The hydraulic push rod 51 is fixed to the top of the vessel cover 2 through the gantry frame 52. The movable end of the hydraulic push rod 51 is coaxial with the drive rod 33. After the movable end of the hydraulic push rod 51 moves down, it pushes the drive rod 33 down.

[0057] See Figure 2 and Figure 12 As shown, a pressure plate 511 is installed on the movable end of the hydraulic push rod 51. The movable end of the hydraulic push rod 51 and the pressure plate 511 are rotatably connected by a bearing. The bottom of the pressure plate 511 is provided with a positioning hole 512 for positioning the drive rod 33.

[0058] In the above technical solution, the pressure plate 511 can rotate along the bearing, so that when the hydraulic push rod 51 applies downward pressure to the drive rod 33, it does not affect the rotation of the drive rod 33.

[0059] Stirring and mixing mode: The equipment is used for material reaction under normal pressure. In this mode, the overflow valve 181 remains open, and liquid is injected into the vessel 1 through the feeding pipe 13. The liquid level is observed through the light-transmitting plate 131. Liquid injection stops when the liquid level is lower than the height of the vessel lid 2 and reaches the lower scale mark of the light-transmitting plate 131. The float 31 is suspended on the liquid surface by buoyancy. The drive device 4 drives the floating stirring mechanism 3 to rotate at a preset speed. As the injected liquid level rises, the floating stirring mechanism 3 automatically floats up, achieving full-process stirring from bottom to top and ensuring uniform mixing of materials. In this state, the cleaning device 34 retracts and the stirring unit 35 extends, focusing on completing the material stirring and reaction operation.

[0060] Cleaning Mode: After the reaction is complete, the overflow valve 181 is closed. High-pressure water is sprayed into the vessel 1 through the external booster pump and connecting pipe 222 via water pipe 221 and nozzle 223 until the vessel 1 is filled with clean water. The controller presets parameters to control the pressing device 5 to gradually press down the drive rod 33 at a set speed. Simultaneously, the drive device 4 drives the floating stirring mechanism 3 to rotate slowly. The pressing process can be continuous or stepped: In stepped pressing, each press involves a fixed stroke (corresponding to a single cleaning vertical height). After reaching the desired depth, the pressing is paused, and the rotation continues for cleaning. After completing this section of cleaning, the pressing continues until the floating stirring mechanism 3 reaches its bottom limit position. When the pressing device 5 reaches its limit position, the cleaning strip 3102 precisely adheres to the inner wall of the material accumulation section 11, coordinating with circumferential rotation to complete a thorough, no-dead-angle cleaning of the inner wall of the vessel 1 and the bottom material accumulation area. After cleaning, wastewater can be discharged through the bottom discharge pipe 12.
