Description

Technical Field

[0001] The invention relates to the technical field of catalyst production, and in particular to a reaction device for catalyst production. Background Art

[0002] A catalyst generally refers to a substance that increases the reaction rate without changing the total standard Gibbs free energy change of the reaction. It can also be described as a substance that can increase the chemical reaction rate without changing the chemical equilibrium in a chemical reaction, and whose quality and chemical properties do not change before and after the chemical reaction. According to statistics, catalysts are used in more than 90% of industrial processes, such as chemical, petrochemical, biochemical, environmental protection, etc. There are many types of catalysts, which can be divided into liquid catalysts and solid catalysts according to their state; they can be divided into homogeneous catalysts and heterogeneous catalysts according to the phase state of the reaction system. Homogeneous catalysts include acids, bases, soluble transition metal compounds and peroxide catalysts. In the production of acrylic acid catalysts, a reaction device is required to concentrate the prepared solution for subsequent processing.

[0003] A Chinese patent document with authorization announcement number CN220328663U discloses a concentration reactor, which drives the jet assembly to move in the reactor body through a hydraulic cylinder, and the airflow formed by the ejected high-pressure gas blows the residual material in the reactor body, so that the adhered material falls off. The processing process does not require contact, reducing contact residue and waste, avoiding wear on the reactor body, ensuring the service life of the reactor body, and improving the efficiency of the entire concentration process.

[0004] However, the structural design of the above-mentioned related technology is as follows: in the process of gradual concentration of the material, the liquid level in the kettle will gradually decrease and the concentration will increase, but the angle and height of the stirring rod in the kettle are inconvenient to change. When the liquid level in the kettle gradually decreases and the concentration gradually increases, the stirring rod above the liquid surface cannot contact the material, and the stirring rod below the liquid surface cannot provide effective shear force to the material, so that the subsequent concentration efficiency of the material gradually decreases, thereby affecting the production efficiency.

[0005] Therefore, a reaction device for catalyst production is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The present invention provides a reaction device for catalyst production, aiming to solve the problem in the related art that during the concentration process of materials, the concentration efficiency of the materials is easily reduced due to the reduction of liquid level and increase of viscosity.

[0007] The catalyst production reaction device of the present invention comprises a shell and a driving mechanism, wherein a stirring mechanism meshing with the driving mechanism is rotatably connected inside the shell to stir materials, and an adjusting mechanism for adjusting the stirring range is provided on the stirring mechanism; The stirring mechanism includes a rotating component, a stirring component 1, a stirring component 2, a stirring component 3 and multiple groups of limiting components. The rotating component is rotatably connected to the inside of the shell. The stirring component 1, the stirring component 2 and the stirring component 3 are distributed on the rotating component from top to bottom. The stirring component 1, the stirring component 2 and the stirring component 3 have paddle 1, paddle 2 and paddle 3 respectively. The multiple groups of limiting components are distributed on the outside of the rotating component. The stirring component 1 and the stirring component 2 are both slidably connected to the limiting component. The adjustment mechanism can drive the stirring component to move down and press the stirring component 2 down to adjust the stirring range of the material. At the same time, the inclination angles of the paddle 1 and the paddle 2 are changed under the action of the limiting component. When the stirring component 2 moves down, it can squeeze the stirring component 3 and change the inclination angle of the paddle 3 to increase the shear force on the material and ensure the concentration efficiency.

[0008] When the liquid level of the material in the shell drops to the point where it leaks out of stirring component one, the stirring component is moved down and re-entered into the material under the restriction of the adjusting mechanism to allow stirring component one to continue stirring. As the material level continues to move downward, the adjusting mechanism continues to drive the stirring component to move down, and at the same time, stirring component one drives stirring component two to move downward. At this time, under the action of the limiting component, the inclination angles of paddle one and paddle two can be changed. Stirring component two squeezes stirring component three during the downward movement, thereby changing the inclination angle of paddle three, so that paddle one, paddle two and paddle three are all in a vertical state, so as to increase the shear force on the material, thereby ensuring the concentration efficiency of the material.

[0009] Preferably, the rotating assembly includes a rotating drum rotatably connected to the inside of the shell and a bevel gear three installed on the outside of the rotating drum, the top end of the rotating drum penetrates the shell and extends to the outside of the shell, and the bevel gear three is meshed with the driving mechanism.

[0010] Preferably, the adjustment mechanism includes a mounting plate, a pneumatic clamp and a lead screw, the mounting plate is mounted on the driving mechanism, the pneumatic clamp is mounted on the mounting plate, the lead screw is rotatably connected to the inside of the pneumatic clamp, and the bottom end of the lead screw is located inside the rotating drum.

[0011] Preferably, the stirring assembly includes a slider threadedly connected to the lead screw and a plurality of rotating rods rotatably connected to the outside of the slider, the blade is installed at one end of the rotating rod, and a shift block is installed on the outside of the other end of the rotating rod, and the shift block can be slidably connected to the limit assembly.

[0012] When the pneumatic clamp is tightened, it can clamp the lead screw to prevent it from rotating. At this time, the lead screw can drive the slider to move down, thereby driving the blade to move down to adjust the stirring range. When the pneumatic clamp is relaxed, the lead screw can be released to allow the lead screw to rotate. At this time, the blade rotates with the drum.

[0013] Preferably, the stirring component 2 includes a slider 2 slidably connected to the outside of the screw and a plurality of rotating rods 2 rotatably connected to the slider 2, two diagonally arranged vertical rods are installed on the top of the slider 2, the paddle 2 is installed at one end of the rotating rod 2, and a shift block 2 is installed at the other end of the rotating rod 2, and the limit assembly is slidably connected to the shift block 2.

[0014] The slider 1 can contact with the vertical rod during the downward movement. As the slider 1 continues to move downward, the slider 1 can drive the slider 2 to move downward through the vertical rod, thereby driving the blade 2 to move downward.

[0015] Preferably, the stirring component three includes a fixed block installed inside the rotating drum and a plurality of rotating rods three rotatably connected to the fixed block, the slider two is elastically slidably connected to the top of the fixed block vertically, the blade three is installed at one end of the rotating rod three, and a shift block three is installed on the outside of the other end of the rotating rod three.

[0016] Preferably, the limit assembly includes a limit frame, inclined plate 1, inclined plate 2 and inclined plate 3, the limit frame is installed on the outside of the rotating drum, and the inclined plate 1, inclined plate 2 and inclined plate 3 are installed on one side of the inner wall of the limit frame in sequence from top to bottom, and the inclined plate 1 and inclined plate 2 can be slidably connected with the shift block 1 to adjust the inclination angle of the blade 1, and the inclined plate 2 and inclined plate 3 can be slidably connected with the shift block 2 to adjust the inclination angle of the blade 2.

[0017] In the process of slider 1 driving slider 2 to move downward, under the action of inclined plate 1, shift block 1 drives blade 1 to rotate through rotating rod 1 to adjust the angle of blade 1. At the same time, under the action of inclined plate 2, shift block 2 drives blade 2 to rotate through rotating rod 2 to adjust the angle of blade 2, thereby increasing the shear force on the material. When shift block 1 moves to inclined plate 2, shift block 2 moves to inclined plate 3. When slider 1 drives shift block 1 to move to the end of inclined plate 2, shift block 2 moves to the end of inclined plate 3. At this time, blades 1 and 2 are adjusted to a vertical state.

[0018] Preferably, a connecting plate is installed on the outer side of the sliding block 2 near the bottom of the rotating rod 2, and a pressure rod is installed on the connecting plate. The pressure rod can squeeze the shift block 3 to adjust the inclination angle of the blade 3.

[0019] When the slider 2 moves downward, it can drive the pressure rod to move downward. When the pressure rod moves downward, it can squeeze the shift block 3. At this time, the shift block 3 drives the blade 3 to rotate to a vertical state through the rotating rod 2 to further increase the shear force on the material.

[0020] By adopting the above technical scheme, the beneficial effect of the present invention is as follows: when the liquid level of the material in the shell drops to the point where the stirring component 1 leaks out, the stirring component is moved down and re-enters the material under the restriction of the adjusting mechanism, so that the stirring component 1 continues to stir; while the material liquid level continues to move downward, the adjusting mechanism continues to drive the stirring component to move down, and at the same time, the stirring component 1 drives the stirring component 2 to move downward; at this time, under the action of the limiting component, the inclination angles of the paddle 1 and the paddle 2 can be changed, so that the paddle 1 and the paddle 2 are gradually transformed into a vertical state; the stirring component 2 squeezes the stirring component 3 in the process of moving downward, thereby changing the inclination angle of the paddle 3, so that the paddle 1, the paddle 2 and the paddle 3 are all in a vertical state, so as to increase the shear force on the material, thereby ensuring the concentration efficiency of the material.

[0038] When the rotating component 41 rotates, it can drive the stirring component 1 42, the stirring component 2 43 and the stirring component 3 44 to rotate synchronously to accelerate the concentration of the material.

[0039] like Figures 2 to 4As shown, the rotating assembly 41 includes a rotating drum 411 and a bevel gear 3 416. The rotating drum 411 is rotatably connected to the inside of the housing 10. The top of the rotating drum 411 penetrates the sealing disk 28 and extends to the outside of the sealing disk 28. The bevel gear 3 416 is installed on the outside of the top of the rotating drum 411 and meshes with the bevel gear 26.

A stirring frame 414 is installed at the bottom of the connecting frame 413 to stir the material away from the center of the housing 10.

[0040] The motor 23 can drive the rotating drum 411 in the bevel gear 3 416 to rotate through the bevel gear 2 26 , and the rotating drum 411 can drive the stirring frame 414 to rotate through the connecting frame 413 on the fixing ring 412 . At the same time, the rotating drum 411 can also drive the paddle 415 to rotate to stir the material in the shell 10 .

[0041] like Figures 3 to 5 As shown, the stirring assembly 42 includes a slider 421 located on the inner side of the rotating drum 411 and a plurality of stirring members 421 rotatably connected to the outer side of the slider 421. The plurality of stirring members 421 are distributed in a ring shape on the outer side of the slider 421 with the axis of the rotating drum 411 as the center. The number of the stirring members 42 is the same as the number of the limiting assembly 45. The slider 421 is threadedly connected to the lead screw 33.

[0042] The stirring member 1 includes a rotating rod 422, a blade 423 and a shifting block 424. One end of the rotating rod 422 is rotatably connected to the outside of the slider 421, and a torque spring (not shown in the figure) is provided between the slider 421 and the rotating rod 422 to drive the rotating rod 422 to reset. The shifting block 424 is installed on the outside of one end of the rotating rod 422, and the shifting block 424 is horizontally arranged in the initial state. The other end of the rotating rod 422 passes through the rotating drum 411 and the limit assembly 45 in sequence and extends to the outside of the limit assembly 45. The blade 423 is installed on the other end of the rotating rod 422, and the inclination angle of the blade 423 in the initial state is 30°.

[0043] When the lead screw 33 is clamped by the pneumatic clamp 32, the lead screw 33 is in a fixed state. As the drum 411 continues to rotate, under the limit of the rotating rod 422, the lead screw 33 drives the slider 421 to move downward. At the same time, under the limit of the limit assembly 45, it can push the shift block 424 to rotate around the axis of the rotating rod 422, so that the shift block 424 drives the blade 423 to rotate through the rotating rod 422 to adjust the inclination angle of the blade 423, thereby changing the shear force of the blade 423 on the material, which is convenient for better stirring of the material to ensure the concentration efficiency of the material.

[0044] like Figures 3 to 7 As shown, the stirring assembly 2 43 includes a slider 2 431, a plurality of stirring members 2 and a plurality of extrusion members, and the slider 2 431 is slidably connected to the outside of the lead screw 33. The plurality of stirring members 2 are distributed in a ring shape on the outside of the slider 2 431 with the axis of the rotating drum 411 as the center, and the number of stirring members 1 and stirring members 2 is the same.

Two diagonally arranged vertical rods 435 are installed at the top of the slider 2 431, and two diagonally arranged sliding rods 436 are installed at the bottom of the slider 2 431.

[0045] Continue to refer Figures 3 to 7 As shown, the stirring member 2 includes a rotating rod 2 432, a blade 2 433, and a shift block 2 434. One end of the rotating rod 2 432 is rotatably connected to the outside of the slider 2 431, and a torque spring (not shown in the figure) is provided between the slider 2 431 and the rotating rod 2 432 to drive the rotating rod 2 432 to reset. The shift block 2 434 is installed on the outside of one end of the rotating rod 2 432. In the initial state, the shift block 2 434 is tilted. The other end of the rotating rod 2 432 passes through the rotating drum 411 and the limit assembly 45 in sequence and extends to the outside of the limit assembly 45. The blade 2 433 is installed on the other end of the rotating rod 2 432. In the initial state, the inclination angle of the blade 2 433 and the blade 1 423 is the same. A groove is provided on the outside of the rotating drum 411 for the rotating rod 1 422 and the rotating rod 2 432 to slide up and down.

[0046] like Figures 5 to 7 As shown, the extrusion member includes a connecting plate 437 and a pressure rod 438. The connecting plate 437 is installed at the bottom of one side of the slider 431, and the pressure rod 438 is installed at the bottom of the connecting plate 437. The shape of the pressure rod 438 is a Z straight line.

[0047] When the shift block 424 starts to rotate, the bottom of the slider 421 contacts the vertical rod 435. At this time, the slider 421 drives the slider 431 to move downward through the vertical rod 435. At this time, under the limit of the limit assembly 45, the shift block 434 can be pushed to rotate around the axis of the rotating rod 432. At the same time, the shift block 434 drives the blade 433 to rotate through the rotating rod 432 to adjust the inclination angle of the blade 433, thereby changing the shear force of the blade 433 on the material.

[0048] like Figures 3 to 5 and Figure 7 As shown, the stirring assembly 3 44 includes a fixed block 441 and a plurality of stirring members 3, and the plurality of stirring members 3 are distributed in a ring shape on the outside of the fixed block 441 with the axis of the rotating drum 411 as the center. The fixed block 441 is installed at the lower part of the inside of the rotating drum 411 and is rotatably connected to the bottom end of the lead screw 33. The bottom end of the slide bar 436 passes through the fixed block 441 and extends to the outside of the fixed block 441. The fixed block 441 is slidably connected to the slide bar 436.

In this embodiment, the elastic member 445 is a coil spring.

[0049] The stirring member 3 includes a rotating rod 3 442, a blade 3 443 and a shift block 3 444. One end of the rotating rod 3 442 is rotatably connected to one side of the fixed block 441, and a torque spring (not shown in the figure) is provided between the fixed block 441 and the rotating rod 3 442 to drive the rotating rod 3 442 to reset. The pressure rod 438 is located above the shift block 3 444, and the shift block 3 444 is installed on the outside of one end of the rotating rod 3 442. In the initial state, the inclination angles of the shift block 2 434 and the shift block 3 444 are opposite, and the other end of the rotating rod 3 442 passes through the rotating drum 411 and the limit assembly 45 in sequence and extends to the outside of the limit assembly 45. The blade 3 443 is installed on the other end of the rotating rod 3 442. In the initial state, the inclination angles of the blade 3 443 and the blade 1 423 are opposite.

[0050] During the downward movement of slider 2 431, slider 2 431 can drive pressure rod 438 to contact with shift block 3 444 through connecting plate 437. When slider 2 431 continues to move downward, pressure rod 438 can drive rotating rod 3 442 to rotate through shift block 3 444, thereby adjusting the inclination angle of blade 3 443 to further increase the shear force, thereby ensuring the concentration efficiency.

[0051] like Figures 3 to 7As shown, the limiting assembly 45 includes a limiting frame 451, an inclined plate 1 452, an inclined plate 2 453 and an inclined plate 3 454. The limiting frame 451 is installed on the outside of the rotating drum 411, and a strip groove corresponding to the groove on the rotating drum 411 is opened on the limiting frame 451 to allow the rotating rod 1 422 and the rotating rod 2 432 to slide. The inclined plate 1 452, the inclined plate 2 453 and the inclined plate 3 454 are installed on one side of the inner wall of the limiting frame 451 from top to bottom, and one side of the inclined plate 1 452, the inclined plate 2 453 and the inclined plate 3 454 all have an inclined surface. The inclination angle of the upper slope of inclined plate 2 453 is twice the inclination angle of the upper slope of inclined plate 1 452, and the inclination angle of the upper slope of inclined plate 3 454 is twice the inclination angle of the upper slope of inclined plate 2 453. In the initial position, shift block 1 424 is located above inclined plate 1 452, and shift block 2 434 is in contact with the top of one side of the upper slope of inclined plate 2 453.

[0052] Working principle: When concentrating the material, add the material into the shell 10 and close the shell 10, then make the pneumatic clamp 32 loosen the screw 33, and finally start the motor 23. At this time, the motor 23 can drive the rotating drum 411 in the bevel gear 3 416 to rotate through the bevel gear 2 26, and the rotating drum 411 drives the stirring frame 414 and the paddle 415 to rotate synchronously. At the same time, the rotating drum 411 also drives the slider 1 421, the slider 2 431 and the fixed block 441 to rotate synchronously, thereby driving the blade 1 423, the blade 2 433 and the blade 3 443 to rotate synchronously to stir the material. When the liquid level of the material in the shell 10 drops to the point where the blade 1 423 leaks out, the pneumatic clamp 32 fixes the screw 33.

[0053] At this time, the lead screw 33 drives the slider 421 to move downward, thereby driving the blade 423 to enter the material again, so that the blade 423 continues to stir the material, and prevents the blade 423 from scraping the material, thereby preventing the blade 423 from driving the material to the inner wall of the housing 10, thereby avoiding the waste of the material. When the slider 421 stops moving downward, the shifting block 424 contacts the top of the inclined plate 452, and the slider 421 contacts the top of the vertical rod 435.

[0054] When the material level continues to drop, the viscosity of the material increases. At this time, the lead screw 33 continues to drive the slider 1 421 downward, and the slider 1 421 drives the slider 2 431 downward through the vertical rod 435. During the downward movement of the slider 2 431, the elastic member 445 is compressed. At the same time, under the action of the inclined plate 1 452 and the inclined plate 2 453, the shift block 1 424 drives the blade 1 423 on the rotating rod 1 422 to rotate, and the shift block 2 434 drives the blade 2 433 on the rotating rod 2 432 to rotate to adjust the angle of the blade 1 423 and the blade 2 433, thereby increasing the shear force of the blade 1 423 and the blade 2 433 on the material, so as to make the material react better. When the slider 1 421 and the slider 2 431 stop moving downward, the shift block 1 424 is located at the bottom of one side of the inclined plate 1 452, and the shift block 2 434 is located at the bottom of one side of the inclined plate 2 453.

[0055] When the material level drops again, the viscosity of the material continues to increase. At this time, the lead screw 33 drives the slider 1 421 to move downward again, and the slider 2 431 moves downward synchronously. At this time, under the action of the inclined plate 2 453, the paddle 1 423 is rotated to a vertical state. At the same time, under the action of the inclined plate 3 454, the paddle 2 433 is rotated to a vertical state. In the process of the slider 2 431 moving downward, the slider 2 431 squeezes the shift block 3 444 through the pressure rod 438. At this time, the shift block 3 444 drives the paddle 3 443 on the rotating rod 3 442 to rotate. When the slider 2 431 moves downward to the extreme position, the paddle 3 443 is rotated to a vertical state, thereby further increasing the shear force on the material, facilitating the material to continue to react, thereby ensuring the concentration efficiency of the material.
