Description

Technical Field

[0001] This invention relates to the field of chemical production technology, specifically to a centrifugal filtration device for the production of alkylcyclohexylcyclohexane carboxylic acid. Background Technology

[0002] Alkylcyclohexylcyclohexanecarboxylic acid, as a high-performance organic intermediate, is widely used in pharmaceutical synthesis, specialty materials, and polymer science. Its production process involves heterogeneous catalytic reactions and crystallization separation, with the solid-liquid separation stage directly affecting product purity and yield.

[0003] Traditional centrifugal filtration typically operates at a constant speed, resulting in centrifugal force remaining at a fixed level. Under these conditions, it is impossible to completely separate substances with lower density or irregular shapes, thus affecting product purity and yield. The stable centrifugal speed often causes solid material to form a clogging layer on the filter screen or filter bag. This clogging not only increases filtration resistance but also makes cleaning and maintenance more complex and time-consuming. Solid deposition not only slows down the filtration rate but may also change the pore structure of the filter screen, further affecting the filtration effect and ultimately leading to a decrease in production efficiency. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a centrifugal filtration device for the production of alkylcyclohexylcyclohexane carboxylic acid, comprising an outer casing, a frequency conversion drive assembly installed inside the outer casing, bent connecting rods fixedly installed on both sides of the bottom of the outer casing, a fixed plate fixedly installed at the end of the bent connecting rods away from the outer casing, a drive assembly fixedly installed at the bottom of the fixed plate, two connecting columns fixedly installed at the bottom of the fixed plate, a connecting box fixedly installed at the bottom of the two connecting columns, a drain pipe connected to the bottom of the connecting box, three rotating connecting pipes rotatably connected to the top of the connecting box, and a filtration assembly rotatably installed through the top of the three rotating connecting pipes through the fixed plate.

[0006] Preferably, the variable frequency drive assembly includes a drive frame, and variable frequency gear ring one, variable frequency gear ring two, and variable frequency gear ring three are fixedly installed inside the drive frame. Variable frequency gear ring one is located on top of variable frequency gear ring two, and variable frequency gear ring two is located on top of variable frequency gear ring three. The interiors of variable frequency gear ring one, variable frequency gear ring two, and variable frequency gear ring three each have teeth at only 120 degrees, and the teeth inside variable frequency gear ring one, variable frequency gear ring two, and variable frequency gear ring three are staggered.

[0007] Preferably, a rotating ring is fixedly installed at the bottom of the transmission frame, and a transmission gear ring is fixedly installed on the side of the rotating ring away from the transmission frame. The rotating ring is rotatably installed between the outer sleeve and the fixed plate.

[0008] Preferably, the drive assembly includes a drive component, an output end of which is fixedly mounted with a drive gear, the outer side of which meshes with the inner side of the transmission gear ring, a fixed base is fixedly mounted at the bottom of the drive assembly, the top of the fixed base is fixedly connected to the bottom of the fixed plate, a circular groove is provided at the bottom of the transmission frame, and the top of the fixed plate is rotatably mounted on the inner side of the circular groove.

[0009] Preferably, the spun filter assembly includes three rotating cylinders and three filter bag bodies. Variable frequency gear three, variable frequency gear two, and variable frequency gear one are fixedly installed on the outer sides of each of the three rotating cylinders. A connecting ring is fixedly installed inside each of the three rotating cylinders. A spun filter frame is fixedly installed inside each of the connecting rings, and a spun filter hole is opened inside each of the spun filter frames. A filter bag ring is fixedly installed on the top of each of the three filter bag bodies.

[0010] Preferably, the first variable frequency gear is located on top of the second variable frequency gear, and the second variable frequency gear is located on top of the third variable frequency gear. The position of the first variable frequency gear corresponds to the position of the first variable frequency gear ring, the position of the second variable frequency gear corresponds to the position of the second variable frequency gear ring, and the position of the third variable frequency gear corresponds to the position of the third variable frequency gear ring.

[0011] Preferably, the bottoms of the three rotating cylinders are respectively connected to the ends of the three rotating connecting pipes that are away from the connecting box.

[0012] Preferably, both the connecting ring and the filter frame have assembly slots at their tops, and assembly blocks are fixedly installed on the outer side of the filter bag ring. The assembly blocks are snapped into the inner side of the assembly slots, and the dimensions of the outer contour of the filter bag ring match the dimensions of the inner contour of the top of the filter frame.

[0014] Preferably, the bottom of the outer casing is fixedly equipped with four support legs, which are installed in a rectangular symmetrical arrangement at the four corners of the bottom of the outer casing.

[0015] Compared with existing technologies, the advantages of this invention are: by using a variable frequency drive component, the device can continuously change the rotation speed of the centrifugal filter assembly. This continuous speed change dynamically adjusts the centrifugal force, ensuring that materials of different densities and particle sizes are subjected to varying centrifugal forces during centrifugation. This dynamic adjustment of centrifugal force enables a more thorough separation of the dry and wet components in the material, resulting in a more significant separation effect compared to traditional stable-speed centrifugal filter devices. Speed ​​changes can cause materials to form more complex flow patterns within the sling filter assembly. During the variable frequency rotation, the material will continuously change its direction and speed, increasing the contact opportunities between the material and the sling filter assembly. More contact allows the liquid to be more fully ejected through the sling filter holes, thereby improving separation efficiency and shortening the sling filter time. Continuous speed changes make it easier to remove material adhering to the spun filter assembly. In traditional stable speed spun filters, some material may adhere to the spun filter assembly due to insufficient centrifugal force, resulting in residue. The speed changes of this device can break this adhesion state and remove the adhering material through constantly changing centrifugal force, thereby reducing the material residue on the spun filter assembly and improving the material recovery rate.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-7 This invention provides a technical solution: a centrifugal filtration device for the production of alkylcyclohexylcyclohexane carboxylic acid, comprising an outer tank 1, a frequency conversion drive assembly installed inside the outer tank 1, bent connecting rods 13 fixedly installed on both sides of the bottom of the outer tank 1, a fixed plate 31 fixedly installed at the end of the bent connecting rods 13 away from the outer tank 1, a drive assembly fixedly installed at the bottom of the fixed plate 31, two connecting columns 5 fixedly installed at the bottom of the fixed plate 31, a connecting box 6 fixedly installed at the bottom of the two connecting columns 5, a drain pipe 7 connected to the bottom of the connecting box 6, three rotating connecting pipes 12 rotatably connected to the top of the connecting box 6, and a filtration assembly rotatably installed through the top of the three rotating connecting pipes 12 through the fixed plate 31.

[0026] The working principle of the above technical solution is as follows: First, the material to be centrifuged is placed inside the centrifuge assembly inside the outer casing 1. Then, the drive assembly is started, and the centrifuge assembly is rotated through the frequency conversion transmission assembly, thereby centrifuging the material inside the centrifuge assembly. The centrifuged liquid is transferred to the connecting box 6 through the rotating connecting pipe 12. Then, the valve on the outside of the drain pipe 7 can be opened to discharge the centrifuged liquid. In addition, through the set frequency conversion transmission assembly, the device can continuously change the rotation speed of the centrifuge assembly. The uninterrupted speed change can dynamically adjust the centrifugal force, so that materials of different densities and particle sizes are subjected to different centrifugal forces during centrifugation. This dynamic centrifugal force adjustment can more thoroughly separate the dry and wet components in the material, compared with the traditional stable speed. The centrifugal filtration device offers a more significant separation effect. Furthermore, the variable speed allows for more complex flow patterns within the filtration assembly. During the variable frequency rotation, the material continuously changes its direction and speed, increasing the contact opportunities between the material and the filtration assembly. This increased contact allows the liquid to be more fully ejected through the centrifugal orifice 30, thereby improving separation efficiency and shortening filtration time. Moreover, the continuous speed variation makes it easier to remove material adhering to the filtration assembly. In traditional stable-speed centrifugal filtration, some material may adhere to the assembly due to insufficient centrifugal force, resulting in residue. This device's speed variation breaks this adhesion, using constantly changing centrifugal force to remove the adhering material, thus reducing residue on the filtration assembly and improving material recovery rate.

[0027] In another implementation scheme, such as Figures 1-7As shown, the variable frequency drive assembly includes a drive frame 19. Variable frequency gear rings 14, 15, and 16 are fixedly installed inside the drive frame 19. Variable frequency gear ring 14 is located on top of variable frequency gear ring 15, and variable frequency gear ring 15 is located on top of variable frequency gear ring 16. Each of the variable frequency gear rings 14, 15, and 16 has teeth at only 120 degrees, and the teeth inside are staggered. A rotating ring 17 is fixedly installed at the bottom of the drive frame 19. The rotating ring 17 is located at... A transmission gear ring 11 is fixedly installed on one side of the transmission frame 19. A rotating ring 17 is rotatably installed between the outer casing 1 and the fixed plate 31. The drive assembly includes a drive assembly 9. A drive gear 10 is fixedly installed at the output end of the drive assembly 9. The outer side of the drive gear 10 meshes with the inner side of the transmission gear ring 11. A fixed seat 8 is fixedly installed at the bottom of the drive assembly 9. The top of the fixed seat 8 is fixedly connected to the bottom of the fixed plate 31. A circular groove 18 is opened at the bottom of the transmission frame 19. The top of the fixed plate 31 is rotatably installed inside the circular groove 18. The sifting filter assembly includes three rotating cylinders 27 and... Three filter bag bodies 23 and three rotating cylinders 27 are each fixedly mounted with a frequency conversion gear 3 20, a frequency conversion gear 21, and a frequency conversion gear 1 22 on their outer sides. A connecting ring 26 is fixedly mounted inside each of the three rotating cylinders 27, and a filter-throwing frame 28 is fixedly mounted inside each connecting ring 26. Each filter-throwing frame 28 has a filter-throwing hole 30 inside. A filter bag ring 25 is fixedly mounted on the top of each of the three filter bag bodies 23. Frequency conversion gear 1 22 is located on top of frequency conversion gear 21, and frequency conversion gear 21 is located on top of frequency conversion gear 3 20. The positions of frequency conversion gear 1 22 and frequency conversion gear ring 1 14 are... The positions of the variable frequency gear 21 and the variable frequency gear ring 25 are corresponding, and the positions of the variable frequency gear 3 and the variable frequency gear ring 3 are corresponding. The bottoms of the three rotating cylinders 27 are respectively connected to the ends of the three rotating connecting pipes 12 away from the connecting box 6. The tops of the connecting ring 26 and the filter frame 28 are provided with assembly slots 29. The outer side of the filter bag ring 25 is fixedly installed with assembly blocks 24, and the assembly blocks 24 are snapped into the inner side of the assembly slots 29. The outer contour of the filter bag ring 25 matches the inner contour of the top of the filter frame 28.

[0028] First, the filter bag body 23 is snapped into the inside of the filter frame 28, and the assembly block 24 is snapped into the inside of the assembly slot 29. Then, the material is placed inside the filter bag body 23. After that, the drive assembly 9 is started. The output end of the drive assembly 9 can drive the drive gear 10 to rotate, thereby driving the transmission gear ring 11 to rotate. This, in turn, drives the transmission frame 19 to rotate through the rotating ring 17, thereby driving the variable frequency gear ring 14, variable frequency gear ring 15, and variable frequency gear ring 16 to rotate. 16 passes sequentially through the outer sides of frequency conversion gear 1 22, frequency conversion gear 21, and frequency conversion gear 3 20, thereby driving the rotating cylinder 27 to rotate at a frequency conversion rate. This, in turn, drives the filter frame 28 to rotate via the connecting ring 26, which in turn drives the filter bag body 23 to rotate. This achieves the slinging and filtration of the material inside the filter bag body 23, thus separating the dry and wet components in the material. The slinged liquid can be discharged through the rotating connecting pipe 12 and collected inside the connecting box 6, and then discharged through the drain pipe 7, thereby achieving slinging and facilitating the subsequent production of alkylcyclohexylcyclohexane carboxylic acid.

[0029] In another implementation scheme, such as Figures 1-7 As shown, a lid 2 is installed on the top of the outer casing 1 via a hinge, a handle 3 is fixedly installed on the outside of the lid 2, and a support leg 4 is fixedly installed on the bottom of the outer casing 1. There are four support legs 4, and the four support legs 4 are installed in a rectangular symmetrical arrangement at the four corners of the bottom of the outer casing 1.

[0030] The handle 3 allows the lid 2 to be easily opened from the top of the outer casing 1, facilitating the replacement of the filter bag body 23 and the addition of materials to the inside of the filter bag body 23. In addition, the three or four support legs 4 can support the outer casing 1, thereby keeping the bottom of the drain pipe 7 away from the ground, which facilitates the collection of the liquid discharged from the drain pipe 7.

[0031] Working principle: First, the filter bag body 23 is snapped into the inside of the sling filter frame 28, and the assembly block 24 is snapped into the inside of the assembly slot 29. Then, the material is placed inside the filter bag body 23. Next, the drive assembly 9 is activated. The output end of the drive assembly 9 drives the drive gear 10 to rotate, which in turn drives the transmission gear ring 11 to rotate. This, in turn, drives the transmission frame 19 to rotate via the rotating ring 17, which in turn drives the variable frequency gear rings 14, 15, and 16 to rotate. These gear rings then pass sequentially past the outer sides of the variable frequency gears 22, 21, and 20, respectively, causing the rotating cylinder 27 to rotate. This, in turn, drives the sling filter frame 28 to rotate via the connecting ring 26, which in turn drives the filter bag body 23 to rotate, thus achieving the rotation of the material inside the filter bag body 23. The material is centrifuged to separate the dry and wet components. The liquid discharged after centrifugation can be discharged through the rotating connecting pipe 12 and collected into the interior of the connecting box 6. Then it can be discharged through the drain pipe 7, thus realizing centrifugation and facilitating the subsequent production of alkylcyclohexylcyclohexane carboxylic acid. The handle 3 makes it easy to open the lid 2 from the top of the outer tank 1, which facilitates the replacement of the filter bag body 23 and the addition of materials to the inside of the filter bag body 23. In addition, the three or four support legs 4 can support the outer tank 1, so that the bottom of the drain pipe 7 is far away from the ground, which facilitates the collection of the liquid discharged from the drain pipe 7. Through the set frequency conversion drive component, the device can continuously change the rotation speed of the centrifugation component. The continuous speed change can dynamically adjust the centrifugal force, so that materials of different densities and particle sizes are subjected to different centrifugal forces during centrifugation. This dynamic centrifugal force adjustment can more thoroughly separate the dry and wet components in the material. Compared with traditional stable speed centrifugal filtration devices, the separation effect is more significant. In addition, speed changes can cause the material to form a more complex flow pattern within the centrifugal filtration component. During the variable frequency rotation, the material will continuously change its direction and speed, increasing the contact opportunities between the material and the centrifugal filtration component. More contact allows the liquid to be more fully ejected through the centrifugal filtration holes 30, thereby improving separation efficiency and shortening the centrifugal filtration time. Moreover, the continuous speed changes make it easier to remove the material adhering to the centrifugal filtration component. In traditional stable speed centrifugal filtration, some material may adhere to the centrifugal filtration component due to insufficient centrifugal force, resulting in residue. The speed changes of this device can break this adhesion state and remove the adhering material through continuously changing centrifugal force, thereby reducing the material residue on the centrifugal filtration component and improving the material recovery rate.
