Description

Technical Field

[0001] This invention relates to fatty alcohol treatment technology, specifically to a fatty alcohol carbonyl removal device and process that utilizes sodium borohydride for cyclic material processing. Background Technology

[0002] The carbonyl group is an unsaturated chemical group. When producing surfactants from fatty alcohols, the carbonyl group can undergo side reactions with other materials, affecting product quality. The currently popular method for decarbonylating fatty alcohols is to preheat the alcohol and then pass it through a hydrogenation tower for a hydrogenation decarbonylation reaction. However, this process has drawbacks: high safety risks, high investment costs, and it is not suitable for simple decarbonylation treatment of fatty alcohols.

[0003] The decarbonylation process of fatty alcohols was then improved by using a purification agent (sodium borohydride) for cyclic material processing. The process route is simple, reasonable, and novel, with minimal investment, which improves the production efficiency of the equipment.

[0004] However, existing equipment for decarbonylating fatty alcohols using purification reagents (sodium borohydride) has difficulty guaranteeing the reaction rate between sodium borohydride and fatty alcohols, mainly due to the poor mixing rate between the two, resulting in a slow reaction rate that increases the time required for decarbonylating fatty alcohols. Summary of the Invention

A counterweight slider is slidably installed in the sliding groove. A connecting rod is rotatably installed on the counterweight slider. The end of the connecting rod away from the counterweight slider is connected to a connecting kit disposed in the rotating rod. The connecting kit is connected to the loading box.

[0016] As a further embodiment of the present invention: the connecting kit includes a telescopic shaft slidably disposed within the rotating rod, and the connecting rod passes through the guide groove and is rotatably connected to the telescopic shaft;

[0017] A limiting plate is also provided at the end of the telescopic shaft away from the connecting rod, and the limiting plate is slidably connected to the connecting sleeve fixedly installed on the loading box;

[0018] The telescopic shaft is provided with a protruding ring that passes through the guide groove at the end away from the limiting plate, and a No. 1 spring is sleeved on the rotating rod. One end of the No. 1 spring is connected to the protruding ring, and the other end is connected to the rotating plate.

[0019] As a further embodiment of the present invention: the vibration assembly includes a cam rotatably mounted on the horizontal plate, the cam being connected to the rotating rod via a No. 3 belt, and the cam abutting against an abutting wheel disposed on the horizontal plate, the abutting wheel being connected to the horizontal plate via an elastic structure;

[0020] The vibration assembly also includes a vertical plate connected to the elastic structure, and the vertical plate is connected to the telescopic shaft via a push structure.

[0021] As a further embodiment of the present invention: the elastic structure includes a hysteresis groove disposed on the horizontal plate, a hysteresis block slidably installed in the hysteresis groove, the hysteresis block being slidably connected to a horizontal shaft disposed in the hysteresis groove, a second spring being sleeved on the horizontal shaft, one end of the second spring being connected to the inner wall of the hysteresis groove, and the other end being connected to the hysteresis block;

[0022] The hysteresis block is fixedly connected to the vertical plate.

[0023] As a further embodiment of the present invention: the pushing structure includes a connecting kit that connects the telescopic shaft and the upright plate, a drive plate is fixedly connected to the connecting kit, and an inclined groove is formed on the drive plate;

[0024] The pushing structure also includes a connecting plate fixedly connected to the connecting sleeve. A pulley is rotatably mounted on one end of the connecting plate away from the connecting sleeve, and the pulley can roll within the inclined groove.

[0025] As a further embodiment of the present invention: the connecting kit includes a follower plate rotatably connected to the telescopic shaft, the follower plate is provided with a fitting groove along its length direction, a fitting block is slidably installed in the fitting groove, and the fitting block is connected to a follower sleeve slidably disposed on the upright plate through a connecting plate;

[0026] The interlocking block is fixedly connected to the drive board.

[0027] A process for removing carbonyl value from fatty alcohols, using the aforementioned fatty alcohol carbonyl value removal equipment, includes the following steps:

[0028] Step 1: Pass the fatty alcohol to be treated into the reaction chamber;

[0029] Step 2: Start the stirring assembly. The stirring assembly can drive the fatty alcohol to rotate in the reaction chamber and, under the guidance of the baffle, make the fatty alcohol move towards the loading box.

[0030] Step 3: The follower component moves in tandem with the stirring component, causing the loading box to move towards the fatty alcohol until the loading box moves below the surface of the fatty alcohol:

[0031] Step 4: The vibration component moves synchronously with the follower component to make the loading box vibrate;

[0032] Step 5: After the reaction is complete, drain the fatty alcohol from the reaction chamber to complete the removal of the carbonyl value of the fatty alcohol.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] The stirring components can rotate the fatty alcohol solution and give the fatty alcohol solution at the bottom an upward force, thus making the fatty alcohol more evenly distributed in the solution. On the other hand, the fatty alcohol solution can rotate with the stirring blades and collide with the loading box under the guidance of the guide plate, so that the fatty alcohol solution collides with sodium borohydride and improves the reaction efficiency of the two.

[0035] By setting up a follow-up component, when processing fatty alcohol solution, the operation of the follow-up drive device can drive the rotating plate to rotate, thereby causing the counterweight slider to generate centrifugal force. Under the action of centrifugal force, the loading box moves towards the fatty alcohol solution, achieving the effect of linkage between the height of the loading box and the working state of the drive device, improving the integration of the equipment and the integration of operation, and reducing the difficulty of operation.

[0036] The vibration component allows the drive plate to reciprocate when the rotating rod rotates, enabling the connecting sleeve to reciprocate up and down along the length of the telescopic shaft. This, in turn, drives the loading box to reciprocate up and down, creating a vibration effect that allows the sodium borohydride to tumble within the loading box, thereby increasing the reaction rate between the sodium borohydride and the fatty alcohol solution.

[0045] 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.

[0046] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0047] Please see Figures 1 to 7 In this embodiment of the invention, the fatty alcohol carbonyl removal device using sodium borohydride for circulating material includes: a reaction chamber 1, a stirring assembly, a follow-up assembly, and a vibration assembly. When processing the fatty alcohol solution, the follow-up drive device 2 drives the rotating plate 12 to rotate, causing the counterweight slider 13 to generate centrifugal force. Under the action of centrifugal force, the loading box 19 moves towards the fatty alcohol solution, achieving a linkage between the height of the loading box 19 and the working state of the drive device 2. This improves the integration of the equipment and its integrated operation, reducing operational difficulty. Simultaneously, when the rotating rod 7 rotates, the drive plate 20 can reciprocate, allowing the connecting sleeve 16 to reciprocate along the length of the telescopic shaft 14, thereby driving the loading box 19 to reciprocate, creating a vibration effect that allows the sodium borohydride to tumble within the loading box 19, increasing the reaction rate between the sodium borohydride and the fatty alcohol solution.

[0048] Specifically, the reaction chamber 1 contains a loading box 19 for holding sodium borohydride, and a guide plate 32 is fixed on the inner wall of the reaction chamber 1.

[0049] The stirring assembly is disposed inside the reaction chamber 1. The stirring assembly can generate a rotational force on the fatty alcohol placed inside the reaction chamber 1. The stirring assembly includes a drive device 2 fixedly installed on the reaction chamber 1. The output shaft of the drive device 2 passes through the reaction chamber 1 and is connected to a stirring blade 3.

[0050] In use, the fatty alcohol solution to be treated is introduced into the reaction chamber 1, and then the drive device 2 is controlled to work. When the drive device 2 is working, it will drive the stirring blade 3 connected to its output shaft to rotate. When the stirring blade 3 rotates, it can drive the fatty alcohol solution to rotate and give the fatty alcohol solution at the bottom an upward force, thereby making the fatty alcohol more evenly distributed in the solution. On the other hand, the fatty alcohol solution can rotate with the stirring blade 3 and collide with the loading box 19 under the guidance of the guide plate 32, so that the fatty alcohol solution collides with sodium borohydride and improves the reaction efficiency of the two.

[0051] The output shaft of the drive device 2 is also connected to a transmission rod 5 rotatably mounted on the side of the reaction chamber 1 via a first belt 4. The transmission rod 5 is connected to the follower component via a second belt 6.

[0052] The follower component is disposed inside the reaction chamber 1 and connected to the stirring component. When the stirring component is activated, the follower component can drive the loading box 19 to move below the surface of the fatty alcohol liquid. The follower component includes a horizontal plate 8 fixedly installed on the reaction chamber 1. A rotating rod 7 connected to the second belt 6 is rotatably installed on the horizontal plate 8. The interior of the rotating rod 7 is hollow, and the rotating rod 7 is provided with two guide grooves along its length.

[0053] The follower assembly also includes a rotating plate 12 fixedly connected to the rotating rod 7. Two sliding grooves 1201 are symmetrically arranged on the rotating plate 12. A counterweight slider 13 is slidably installed in the sliding groove 1201. A connecting rod 11 is rotatably installed on the counterweight slider 13. One end of the connecting rod 11 away from the counterweight slider 13 is connected to a connecting kit disposed in the rotating rod 7. The connecting kit is connected to the loading box 19. The connecting kit includes a telescopic shaft 14 slidably disposed in the rotating rod 7. The connecting rod 11 passes through the guide groove and is rotatably connected to the telescopic shaft 14.

[0054] The telescopic shaft 14 is also provided with a limiting plate 15 at one end away from the connecting rod 11. The limiting plate 15 is slidably connected to the connecting sleeve 16 fixedly installed on the loading box 19.

[0055] The telescopic shaft 14 is provided with a protruding ring 9 that passes through the guide groove at one end away from the limiting plate 15, and a first spring 10 is sleeved on the rotating rod 7. One end of the first spring 10 is connected to the protruding ring 9, and the other end is connected to the rotating plate 12.

[0056] In the initial state, spring 10 is already compressed. At this time, supported by spring 10, protruding ring 9 is at the highest point of its stroke and pulls loading box 19 through telescopic shaft 14, so that loading box 19 is above the surface of fatty alcohol solution. When drive device 2 works, its output shaft will drive rotating rod 7 through belt 4, transmission rod 5 and belt 6, causing rotating plate 12 to rotate with rotating rod 7, thereby causing counterweight slider 13 to make circular motion and generate centrifugal force. At this time, under the action of centrifugal force, the two counterweight sliders 13 will move away from each other and drive telescopic shaft 14 downward through connecting rod 11 to compress spring 10. When telescopic shaft 14 moves downward, loading box 19 will also move downward until loading box 19 is submerged below the surface of fatty alcohol solution, so that sodium borohydride can react with fatty alcohol.

[0057] With the above settings, when processing the fatty alcohol solution, the operation of the follow-up drive device 2 can drive the rotating plate 12 to rotate, causing the counterweight slider 13 to generate centrifugal force. Under the action of centrifugal force, the loading box 19 moves towards the fatty alcohol solution, achieving the effect of linkage between the height of the loading box 19 and the working state of the drive device 2, improving the integration of the equipment and the integration of operation, and reducing the difficulty of operation.

[0058] Please see Figure 4 , Figure 7 The vibration assembly connects the stirring assembly and the loading box 19. When the fatty alcohol rotates, the vibration assembly drives the loading box 19 to vibrate in the vertical direction of space. The vibration assembly includes a cam 30 rotatably mounted on the horizontal plate 8. The cam 30 is connected to the rotating rod 7 through a third belt 31, and the cam 30 abuts against an abutting wheel 29 provided on the horizontal plate 8. The abutting wheel 29 is connected to the horizontal plate 8 through an elastic structure. The elastic structure includes a hysteresis groove 801 provided on the horizontal plate 8. A hysteresis block 26 is slidably installed in the hysteresis groove 801. The hysteresis block 26 is slidably connected to a horizontal shaft 27 provided in the hysteresis groove 801. A second spring 28 is sleeved on the horizontal shaft 27. One end of the second spring 28 is connected to the inner wall of the hysteresis groove 801, and the other end is connected to the hysteresis block 26.

[0059] The hysteresis block 26 is fixedly connected to the vertical plate 25;

[0060] The vibration assembly also includes a vertical plate 25 connected to the elastic structure. The vertical plate 25 is connected to the telescopic shaft 14 through a push structure. The push structure includes a connecting kit that connects the telescopic shaft 14 and the vertical plate 25. A drive plate 20 is fixedly connected to the connecting kit. An inclined groove 2001 is provided on the drive plate 20.

[0061] The pushing structure also includes a connecting plate 17 fixedly connected to the connecting sleeve 16. A pulley 18 is rotatably mounted on one end of the connecting plate 17 away from the connecting sleeve 16. The pulley 18 can roll within the inclined groove 2001.

[0062] The connecting kit includes a follower plate 21 rotatably connected to the telescopic shaft 14. The follower plate 21 is provided with a fitting groove 2101 along its length direction. A fitting block 22 is slidably installed in the fitting groove 2101. The fitting block 22 is connected to a follower sleeve 24 slidably installed on the vertical plate 25 through a connecting plate 23.

[0063] The fitting block 22 is fixedly connected to the drive plate 20.

[0064] Specifically, since the follower plate 21 is rotatably connected to the telescopic shaft 14, and the follower plate 21 is connected to the follower sleeve 24 through the fitting groove 2101, the fitting block 22 and the connecting plate 23, the follower plate 21 and the follower sleeve 24 can maintain a constant height. That is, when the telescopic shaft 14 rises and falls, the follower sleeve 24 and the follower plate 21 can rise and fall synchronously with the telescopic shaft 14.

[0065] Secondly, when the rotating rod 7 rotates, it drives the cam 30 to rotate via the third belt 31. During the rotation of the cam 30, its long axis will periodically abut against the abutting wheel 29, so that the hysteresis block 26 can reciprocate along the length direction of the hysteresis groove 801 under the cooperation of the cam 30, the abutting wheel 29 and the second spring 28, and drive the vertical plate 25 to reciprocate, thereby driving the follower sleeve 24, the connecting plate 23, the fitting block 22 and the drive plate 20 to reciprocate. The drive plate 20 is connected to the connecting sleeve 16 through the inclined groove 2001, the pulley 18 and the connecting plate 17, so that when the drive plate 20 reciprocates, the connecting sleeve 16 can reciprocate up and down along the length direction of the telescopic shaft 14, thereby driving the loading box 19 to reciprocate up and down, which has a certain vibration effect, so that the sodium borohydride can be turned over in the loading box 19 to improve the reaction rate of sodium borohydride and fatty alcohol solution.

[0066] With the above settings, when the rotating rod 7 rotates, the drive plate 20 can reciprocate, so that the connecting sleeve 16 can reciprocate up and down along the length of the telescopic shaft 14, thereby driving the loading box 19 to reciprocate up and down, which has a certain vibration effect, so that the sodium borohydride can be turned over in the loading box 19, thereby increasing the reaction rate of sodium borohydride with fatty alcohol solution.

[0067] As an embodiment of the present invention, a process for removing carbonyl value of fatty alcohols is also proposed, using the aforementioned fatty alcohol carbonyl value removal equipment, comprising the following steps:

[0068] Step 1: Pass the fatty alcohol to be treated into reaction chamber 1;

[0069] Step 2: Start the stirring assembly. The stirring assembly can drive the fatty alcohol to rotate in the reaction chamber 1 and, under the guidance of the guide plate 32, make the fatty alcohol move towards the loading box 19.

[0070] Step 3: The follower component moves in tandem with the stirring component, causing the loading box 19 to move toward the fatty alcohol until the loading box 19 moves below the surface of the fatty alcohol:

[0071] Step 4: The vibration component moves synchronously with the follower component to make the loading box 19 vibrate;

[0072] Step 5: After the reaction is complete, drain the fatty alcohol from reaction chamber 1 to remove the carbonyl value of the fatty alcohol.

[0073] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
