[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1 - Fig.10As shown, the present invention discloses a refining tower for the production of caprylic acid glyceryl ester, comprising a fixed tower body 1, a sliding tower body 2 is slidably arranged at the top of the fixed tower body 1, and the sliding tower body 2 controls the vacuum degree inside the fixed tower body 1 by controlling the distance between the sliding tower body 2 and the fixed tower body 1. It should be noted that when the caprylic acid glyceryl ester raw material is subjected to the deodorization operation, the vacuum degree generally required is between 0.1 and 0.5 bar, so when the deodorization kettle is used to deodorize the caprylic acid glyceryl ester raw material, the vacuum degree inside the fixed tower body 1 is controlled to be between 0.1 and 0.5 bar. Since the sliding tower body 2 is slidably arranged at the top of the fixed tower body 1, when the sliding tower body 2 slides upward at the top of the fixed tower body 1, the total internal space of the fixed tower body 1 and the sliding tower body 2 will increase, so that the vacuum degree inside the fixed tower body 1 will decrease, and when the sliding tower body 2 is in the fixed When the top of the tower body 1 slides downward, the total internal space of the fixed tower body 1 and the sliding tower body 2 will decrease, so that the vacuum degree inside the fixed tower body 1 will increase. Therefore, the vacuum degree inside the fixed tower body 1 can be controlled by controlling the distance between the fixed tower body 1 and the sliding tower body 2. A top tower body 3 is arranged at the top of the sliding tower body 2, and a bottom tower body 4 is arranged at the bottom end of the fixed tower body 1. A feeding mechanism 5 is arranged on the top surface of the top tower body 3, and the feeding mechanism 5 is used to inject glyceryl caprylate raw material into the interior of the fixed tower body 1. A steam inlet mechanism 6 is arranged on one side of the fixed tower body 1, and the steam inlet mechanism 6 is used to introduce steam into the interior of the fixed tower body 1. A vacuum pump 7 is arranged at the top of the top tower body 3, and the vacuum pump 7 is used to suck the gas inside the top tower body 3 to form a negative pressure inside the top tower body 3. A discharge pipe 8 is arranged at the bottom end of the bottom tower body 4.

[0034] It should be noted that the fixed tower body 1, the sliding tower body 2 and the top tower body 3 together form a sealed deodorizing kettle. When in use, the glyceryl caprylate raw material can be injected into the interior of the fixed tower body 1 through the feeding mechanism 5, so that the glyceryl caprylate raw material enters the interior of the fixed tower body 1. The temperature of the glyceryl caprylate raw material for deodorization is generally controlled between 150 degrees Celsius and 200 degrees Celsius. Therefore, it is necessary to install electric heaters on the side walls of the fixed tower body 1, the sliding tower body 2 and the top tower body 3, so that the temperature inside the sealed deodorizing kettle can be between 150 degrees Celsius and 200 degrees Celsius. The specific temperature inside the deodorizing kettle is adaptively selected by those skilled in the art according to the specifications of the glyceryl caprylate raw material and the flow rate of the glyceryl caprylate raw material when deodorizing, so as to ensure that the deodorization process is completed when the glyceryl caprylate raw material passes through the discharge pipe 8.

[0035] It should also be noted that a vacuum gauge is installed inside the fixed tower body 1, and the vacuum gauge is used to collect the vacuum degree inside the fixed tower body 1. The installation position and number of the vacuum gauge are adaptively selected by technical personnel in this field according to the specifications of the fixed tower body 1 to ensure that the vacuum degree inside the fixed tower body 1 collected by the vacuum gauge is accurate.

[0036] When the glyceryl caprylate raw material enters the interior of the fixed tower body 1 through the feeding mechanism 5, the glyceryl caprylate raw material will form multiple streams of flowing liquid and dripping liquid inside the fixed tower body 1. On the one hand, it ensures that the fixed tower body 1 can quickly heat the glyceryl caprylate raw material to 150 degrees Celsius to 200 degrees Celsius. On the other hand, it can also promote the volatilization of impurities inside the glyceryl caprylate raw material, thereby greatly improving the deodorization efficiency of the glyceryl caprylate raw material.

[0037] During the deodorization process of the glyceryl caprylate raw material, the vacuum degree inside the fixed tower body 1 is collected in real time by a vacuum gauge. Those skilled in the art can select a preset value between 0.1 bar and 0.5 bar, for example, 0.3 bar can be selected. When the vacuum degree inside the fixed tower body 1 collected in real time by the vacuum gauge is greater than 0.3 bar, it indicates that the vacuum degree inside the fixed tower body 1 is too large. At this time, the sliding tower body 2 can be controlled to slide upward at the top of the fixed tower body 1, and the total internal space of the fixed tower body 1 and the sliding tower body 2 will increase, so that the vacuum degree inside the fixed tower body 1 will decrease. The vacuum degree inside the fixed tower body 1 is reduced to 0.3 bar. When the vacuum degree inside the fixed tower body 1 collected by the vacuum gauge in real time is less than 0.3 bar, it indicates that the vacuum degree inside the fixed tower body 1 is too low. At this time, the sliding tower body 2 can be controlled to slide downward on the top of the fixed tower body 1. The total internal space of the fixed tower body 1 and the sliding tower body 2 will be reduced, so that the vacuum degree inside the fixed tower body 1 will increase, and the vacuum degree inside the fixed tower body 1 will rise to 0.3 bar. The vacuum degree inside the fixed tower body 1 is always within a stable range, thereby ensuring the stability of the deodorization of the caprylic / decanoic acid glyceride raw material.

[0038] In addition, the vacuum degree inside the fixed tower body 1 is adjusted by the distance between the fixed tower body 1 and the sliding tower body 2, and the power of the vacuum pump 7 does not need to be controlled, so that the vacuum pump 7 can always be at a constant operating frequency, thereby ensuring the working stability of the vacuum pump 7. At the same time, the vacuum degree inside the fixed tower body 1 is adjusted by the fixed tower body 1 and the sliding tower body 2, which is fast and efficient, and will not affect the efficiency of the vacuum pump 7 in discharging volatile impurities, thereby greatly improving the deodorization effect of the glyceryl caprylate raw material, and the deodorization kettle can continuously process the glyceryl caprylate raw material, that is, the glyceryl caprylate raw material can be continuously added to the deodorization kettle through the feeding mechanism 5, and the deodorization kettle can continuously and efficiently deodorize the glyceryl caprylate raw material entering, thereby simplifying the deodorization operation of the glyceryl caprylate raw material.

[0039] Example 2

[0040] like Figure 1 - Figure 5As shown, the fixed tower body 1 includes a cylindrical tower body 11, and a plurality of vertical hydraulic cylinders 12 are fixedly connected to the side of the cylindrical tower body 11, and a first flange 13 is fixedly connected to the bottom of the cylindrical tower body 11. It should be noted that a control panel is installed on the side of the fixed tower body 1, and a microprocessor is arranged in the control panel. The microprocessor is used to control the plurality of hydraulic cylinders 12 at the same time. The plurality of vertical hydraulic cylinders 12 are equidistantly arranged on the side of the cylindrical tower body 11.

[0041] A deodorizing mechanism 21 is arranged inside the sliding tower body 2, and a plurality of vertical hydraulic rods 22 are fixedly connected to the side of the sliding tower body 2. The hydraulic rods 22 correspond to and fit with the hydraulic cylinders 12 one by one. The hydraulic cylinders 12 can drive the sliding tower body 2 through the hydraulic rods 22. The outer diameter of the sliding tower body 2 is equal to the inner diameter of the fixed tower body 1, so that the sliding tower body 2 can slide on the top of the inner cavity of the cylindrical tower body 11 on the one hand, and can also ensure the sealing between the cylindrical tower body 11 and the sliding tower body 2 on the other hand, to prevent external air from entering the interior of the cylindrical tower body 11. A built-in cavity 23 is provided inside the sliding tower body 2, and the built-in cavity 23 is directly connected to the inner cavity of the cylindrical tower body 11. A second flange 24 is fixedly connected to the top of the sliding tower body 2, and the second flange 24 is fixedly connected to the bottom surface of the top tower body 3 by bolts.

[0042] When in use, when the vacuum degree inside the fixed tower body 1 collected by the vacuum gauge in real time is greater than 0.3 bar, it indicates that the vacuum degree inside the fixed tower body 1 is too large. At this time, the microprocessor can open the hydraulic cylinder 12, so that the hydraulic cylinder 12 drives the sliding tower body 2 upward through the hydraulic rod 22, and controls the sliding tower body 2 to slide upward on the top of the fixed tower body 1. The total internal space of the fixed tower body 1 and the sliding tower body 2 will increase, so that the vacuum degree inside the fixed tower body 1 will decrease, and the vacuum degree inside the fixed tower body 1 will drop to 0.3 bar. When the vacuum gauge collects the vacuum degree inside the fixed tower body 1 in real time, the vacuum degree inside the fixed tower body 1 will decrease. When it is less than 0.3 bar, it indicates that the vacuum degree inside the fixed tower body 1 is too low. At this time, the microprocessor can open the hydraulic cylinder 12, so that the hydraulic cylinder 12 drives the sliding tower body 2 downward through the hydraulic rod 22, and controls the sliding tower body 2 to slide downward on the top of the fixed tower body 1. The total internal space of the fixed tower body 1 and the sliding tower body 2 will be reduced, so that the vacuum degree inside the fixed tower body 1 will increase, and the vacuum degree inside the fixed tower body 1 will rise to 0.3 bar, so that the vacuum degree inside the fixed tower body 1 is always within a stable range, thereby ensuring the stability of the deodorization of the caprylic decanoic acid glyceride raw material.

[0043] Example 3

[0044] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the deodorizing mechanism 21 includes a bottom ring 211, the top surface of the bottom ring 211 is fixedly connected with a connecting rod 212, the top of the connecting rod 212 is fixedly connected with a liquid collecting tray 213, and a plurality of deodorizing cylinders 215 are arranged inside the liquid collecting tray 213. It should be noted that when the liquid collecting tray 213 receives the glyceryl caprylate raw material, since the glyceryl caprylate raw material will flow, the glyceryl caprylate raw material will be spread on the top surface of the liquid collecting tray 213, and since the vacuum pump 7 sucks gas at the top of the top tower body 3, and the steam inlet mechanism 6 introduces steam from the bottom of the side of the fixed tower body 1, the steam will flow upward at the deodorizing cylinder 215, and the fast-flowing steam will form an air wall to hinder the flow of the glyceryl caprylate raw material, so that the glyceryl caprylate raw material is just at the edge of the deodorizing cylinder 215.

[0045] like Figure 6 and Figure 7 As shown, the deodorizing barrel 215 includes a barrel body 2151, a barrel head 2152 is fixedly connected to the top of the barrel body 2151, a barrel groove 2153 is provided inside the barrel body 2151, a plurality of parallel liquid flow grooves 2154 are provided on the side wall of the barrel groove 2153, a plurality of drip heads 2155 are fixedly connected to the bottom surface of the barrel body 2151, and the positions of the drip heads 2155 correspond to the positions of the liquid flow grooves 2154 one by one. It should be noted that the steam will flow upward in the barrel groove 2153, so that the glyceryl caprylate raw material is just at the edge of the barrel groove 2153. Since the side wall of the barrel groove 2153 is provided with a plurality of parallel liquid flow grooves 2154, the steam will flow upward in the barrel groove 2153, so that the glyceryl caprylate raw material is just at the edge of the barrel groove 2153. The flow trough 2154, so the glyceryl caprylate raw material at the edge of the barrel trough 2153 will flow downward along the flow trough 2154 under the action of gravity. In the process of flowing, the glyceryl caprylate raw material will continuously volatilize impurities due to the high temperature and negative pressure, and the volatilized impurities will quickly break away from the glyceryl caprylate raw material under the action of the fast-flowing steam, thereby greatly improving the deodorization effect of the glyceryl caprylate raw material. The technicians in this field set the length of the barrel 2151 according to the flow speed of the glyceryl caprylate raw material in the flow trough 2154, so that the glyceryl caprylate raw material can reach a sufficient deodorization time.

[0046] A fixed block 214 is fixedly connected to the side of the bottom ring 211, and the fixed block 214 is fixedly connected to the inner wall of the fixed tower body 1, and the diameter of the liquid collecting tray 213 is equal to the inner diameter of the sliding tower body 2, thereby ensuring that the sliding tower body 2 will not affect the deodorization mechanism 21 when sliding up and down, that is, the position of the deodorization mechanism 21 is always fixed, thereby ensuring the stability of the deodorization of the caprylic / decanoic acid glyceride raw material.

[0047] It should also be noted that due to the surface tension of the caprylic glycerol raw material itself and the influence of the rapidly flowing upward steam, the downward flow speed of the caprylic glycerol raw material is also related to the size of the flow trough 2154. The technical personnel in this field shall specifically set the size of the flow trough 2154 and the length of the cylinder 2151 according to the overall specifications of the fixed tower body 1 to ensure that the caprylic glycerol raw material reaches a sufficient deodorization time.

[0048] When the glyceryl caprylate raw material flows to the bottom in the flow trough 2154, drops will be formed along the drip head 2155. The glyceryl caprylate raw material that forms drops will greatly increase the specific surface area, thereby greatly improving the volatilization efficiency of impurities in the glyceryl caprylate raw material, and indirectly improving the deodorization efficiency of the glyceryl caprylate raw material.

[0049] Example 4

[0050] like Figure 8 As shown, the bottom tower body 4 includes a bottom main body 41, a collecting chamber 43 is opened inside the bottom main body 41, an external port 44 is opened at the center of the bottom surface of the collecting chamber 43, and a third flange 45 is fixedly connected to the top surface of the bottom main body 41. It should be noted that the inner end of the discharge pipe 8 is connected to the external port 44, the third flange 45 is matched with the first flange 13, and the third flange 45 and the first flange 13 are sealed and connected by bolts. A supporting foot 42 is fixedly connected to the bottom of the bottom main body 41, and the supporting foot 42 is used to support the bottom main body 41. It should also be noted that the bottom of the collecting chamber 43 is arc-shaped to ensure that the caprylic decanoic acid glyceryl dripping on the bottom of the collecting chamber 43 can enter the discharge pipe 8 through the external port 44, thereby realizing the collection of caprylic decanoic acid glyceryl.

[0051] Example 5

[0052] like Fig. 9As shown, the feeding mechanism 5 includes a feeding pipe 51, the bottom end of the feeding pipe 51 is fixedly connected with a disc body 52, the bottom surface of the disc body 52 is fixedly connected with a leakage pipe 53, and there is a gap between the disc body 52 and the top tower body 3. It should be noted that the feeding pipe 51 includes two sections, one of which is a retractable movable pipe, which is fixedly connected to the top of the disc body 52, and the movable pipe is slidably connected to the top surface of the top tower body 3. When the top tower body 3 moves up and down on the sliding tower body 2, the top surface of the top tower body 3 can be slidably connected on the side of the movable pipe to ensure that the top tower body 3 moving up and down does not affect the position of the disc body 52. ​​An electromagnetic valve is arranged inside the feeding pipe 51, and the electromagnetic valve is controlled by the control panel on the fixed tower body 1. The feeding pipe 51 and The external caprylic decanoic acid glyceryl raw material barrel is connected, and the caprylic decanoic acid glyceryl raw material barrel can directly inject caprylic decanoic acid glyceryl raw material into the feed pipe 51, and the flow rate of the caprylic decanoic acid glyceryl raw material in the feed pipe 51 is controlled by the solenoid valve inside the feed pipe 51. Since the interior of the fixed tower body 1 is a negative pressure environment, the caprylic decanoic acid glyceryl raw material in the feed pipe 51 can automatically enter the disc body 52 under the external atmospheric pressure. There are multiple leakage pipes 53 fixedly connected to the bottom surface of the disc body 52, and the number is evenly distributed. The multiple leakage pipes 53 and the deodorizing cylinder 215 on the top surface of the liquid collecting plate 213 are staggered with each other, so that when the leakage pipe 53 transports the caprylic decanoic acid glyceryl raw material to the liquid collecting plate 213, the caprylic decanoic acid glyceryl raw material can be prevented from directly entering the deodorizing cylinder 215.

[0053] Example 6

[0054] like Fig.10 As shown, the vacuum pump 7 includes a pump body 71, one end of the pump body 71 is fixedly connected to an air intake pipe 73, the other end of the pump body 71 is fixedly connected to a drive motor 72, a single screw 74 is installed inside the pump body 71, the output end of the drive motor 72 is connected to the single screw 74 through a coupling, and the top of the pump body 71 is fixedly connected to an air outlet pipe 75. It should be noted that the end of the air intake pipe 73 away from the pump body 71 is connected to the top surface of the top tower body 3 through a telescopic tube. When working, the drive motor 72 is turned on, and the output shaft of the drive motor 72 drives the single screw 74 through the coupling. The high-speed rotating single screw 74 can push the air intake pipe The gas in 73 is transported to the outlet pipe 75 through the pump body 71, and finally outputted from the outlet pipe 75. Since there is a gap between the disc body 52 and the top tower body 3, the flow direction of the gas in the fixed tower body 1 is: steam is inputted into the interior of the fixed tower body 1 by the steam inlet mechanism 6. The steam inlet mechanism 6 is essentially an air inlet pipe. The end of the air inlet pipe away from the fixed tower body 1 is connected to the steam generator to ensure that the steam can be transported to the interior of the fixed tower body 1 through the air inlet pipe. The steam inside the fixed tower body 1 is transported to the top tower body 3 by the deodorization cylinder 215, and finally outputted by the vacuum pump 7 to maintain the negative pressure environment inside the fixed tower body 1.

[0055] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
