[0049] The valve 25 is arranged between the second bevel gear 23 and the third bevel gear 24. The second bevel gear 23 and the third bevel gear 24 are arranged at both ends of the first bevel gear 21, and the first bevel gear 21 is meshed with the second bevel gear 23 and the third bevel gear 24 for transmission.

[0050] The liquid outlet pipe 22 is coaxially arranged with the rotating shaft 225, the spiral auger 2251 is coaxially fixedly connected with the rotating shaft 225, and the outer side of the spiral auger 2251 contacts the inner wall of the guide cylinder 26;

[0053] At the same time, the spiral stirrer 263 on the outer wall of the guide cylinder 26 rotates upward in the opposite direction to the spiral auger 2251, preventing the ethyl lipoic acid ester hydrolyzate from exchanging with the acidified liquid above it at different depths during the stirring process, so that the acidified liquid can more easily and evenly penetrate into the ethyl lipoic acid ester hydrolyzate at different depths.

[0054] See also Figure 3 and Figure 4 The liquid outlet pipe 22 is coaxially connected to the reactor 1, the guide cylinder 26 is coaxially connected to the reactor 1, and a plurality of through holes 261 are formed on the guide cylinder 26, and the liquid outlet pipe 22 is coaxially connected to the guide cylinder 26;

[0055] In this arrangement, since a plurality of through holes 261 are provided on the outer wall of the guide cylinder 26, during the downward conveying process of the spiral auger 2251, the mixture of ethyl lipoate hydrolyzate and acidifying liquid can be continuously dispersed into the ethyl lipoate hydrolyzate at different depths, thereby providing an acidifying environment for the rapid hydrolysis of the ethyl lipoate hydrolyzate.

[0056] See also Figures 5 to 7 The oscillation mechanism is arranged in the reactor 1, and the oscillation mechanism is used to further accelerate the uniform mixing of the acidified liquid and the ethyl thioctic acid hydrolyzate, and at the same time accelerate the hydrolysis efficiency of the ethyl thioctic acid hydrolyzate; the oscillation mechanism comprises: a group of sliding rods 2221, a group of limit blocks 2222, a spring 223 and an adjustment component, a group of sliding rods 2221 is fixedly connected to one end of the mounting block 222 away from the liquid outlet pipe 22, one end of the spring 223 is fixedly connected to the mounting block 222, and the other end is fixedly connected to the mounting cylinder 224;

[0057] The end of the liquid outlet pipe 22 close to the infusion pipe 11 is coaxially fixedly connected with a mounting block 222, and the end of the rotating shaft 225 close to the liquid outlet pipe 22 is coaxially fixedly connected with a mounting cylinder 224. The liquid outlet pipe 22 and the rotating shaft 225 are connected through the mounting block 222 and the mounting cylinder 224. The mounting cylinder 224 is provided with a mounting cavity. The mounting cylinder 224 is provided with a group of sliding limit holes at positions corresponding to a group of sliding rods 2221. The sliding rods 2221 move in the mounting cavity of the mounting cylinder 224 through the sliding limit holes. The limit block 2222 is coaxially fixedly connected with one end of the sliding rod 2221 in the mounting cavity of the mounting cylinder 224.

[0058] The effect of such arrangement is that, since the liquid outlet pipe 22 is coaxially connected with the rotating shaft 225 through the mounting block 222 and the mounting cylinder 224, wherein a group of sliding rods 2221 on the mounting block 222 slides in the mounting cylinder 224, and the diameter of the limit block 2222 fixedly connected to the sliding rod 2221 is larger than the diameter of the sliding limit hole on the mounting cylinder 224, and the mounting cylinder 224 is coaxially fixedly connected with the rotating shaft 225, when the liquid outlet pipe 22 rotates, the rotating shaft 225 rotates accordingly, and does not affect the up and down movement relationship between the rotating shaft 225 and the liquid outlet pipe 22;

[0059] The eccentric shaft 227 disposed at an eccentric position on the connecting disk 226 coaxially fixedly connected to the rotating shaft 225 is disposed in an annular limiting guide groove 311 on the rotating adjusting disk 31. Optionally, a limiting roller is disposed between the eccentric shaft 227 and the annular limiting guide groove 311. The limiting roller is disposed in the annular limiting guide groove 311 and can roll, thereby reducing the friction loss between the eccentric shaft 227 and the rotating adjusting disk 31.

[0060] Since when adjusting the inclination angle between the rotating adjustment disk 31 and the mounting frame 3, as the rotating shaft 225 rotates, there is a distance difference between the eccentric shaft 227 and the rotating adjustment disk 31, so that the rotating shaft 225 drives the spiral auger 2251 to rotate in the guide cylinder 26 and move up and down, forming a shaking effect, quickly mixing the acidified liquid with the ethyl thioctic acid hydrolyzate, and improving the hydrolysis efficiency of the ethyl thioctic acid hydrolyzate.

[0061] See also Figure 1 and Figure 3 The adjusting component is arranged in the reactor 1, and is used to adjust the amplitude of the oscillation of the spiral auger 2251 in the guide cylinder 26. The adjusting component includes: a connecting plate 226, an eccentric shaft 227, a mounting frame 3, a rotating adjusting plate 31, an adjusting screw 4 and a hand wheel 41. The connecting plate 226 is coaxially fixedly connected with one end of the rotating shaft 225 close to the infusion tube 11, and the eccentric shaft 227 is fixedly connected with one end of the connecting plate 226 away from the rotating shaft 225;

[0062] The mounting frame 3 is fixedly mounted on the inner wall of the reactor 1, and the rotating adjustment disk 31 is rotatably connected to the mounting frame 3. An annular limiting guide groove 311 is provided at one end of the rotating adjustment disk 31 close to the guide cylinder 26, and the eccentric shaft 227 is arranged in the annular limiting guide groove 311;

[0063] A threaded mounting hole is provided on the top of the reactor 1, and an adjusting screw 4 is arranged in the threaded mounting hole. One end of the adjusting screw 4 is coaxially fixedly connected to a hand wheel 41, and the other end is rotatably connected to a rotating adjusting disk 31;

[0064] The effect of such arrangement is that the inclination angle of the rotating adjustment disk 31 is adjusted in advance according to the required oscillation amplitude of the ethyl lipoic acid ester hydrolyzate and the acidified liquid, and the hand wheel 41 is rotated so that the adjusting screw 4 and the threaded mounting hole on the top of the reactor 1 cooperate, so that the adjusting screw 4 pushes or pulls the rotating adjustment disk 31, thereby realizing the adjustment of the inclination angle between the rotating adjustment disk 31 and the mounting frame 3, which is convenient for adjusting the oscillation amplitude of the spiral auger 2251 in the guide cylinder 26.

[0065] See also Figure 1 and Figure 6 A sealing bearing is provided at the rotation connection between the guide cylinder 26 and the reactor 1, and a plurality of liquid outlet holes 221 are provided on the liquid outlet pipe 22, and the liquid outlet pipe 22 is connected to the guide cylinder 26 through the plurality of liquid outlet holes 221;

[0066] The effect of such arrangement is that after the hydrolysis reaction of ethyl lipoic acid ester hydrolyzate is completed, the reaction product flows into the liquid outlet pipe 22 through the multiple liquid outlet holes 221 , and the discharge of the reaction product is achieved by controlling the opening of the valve 25 .

[0067] From the above, we can see that the working principle of this application is as follows:

[0068] The ethyl thioctic acid hydrolyzate is introduced into the reactor 1 from the liquid inlet pipe 15 on the reactor 1, the acidified liquid in the acidification tank is transported to the infusion pipe 11 by an external pump, and finally the acidified liquid is sprayed into the reactor 1 by the atomizer on the infusion pipe 11, and an acidification reaction occurs with the ethyl thioctic acid hydrolyzate;

[0069] When the first bevel gear 21 is driven to rotate by the output end of the driving motor 2, the guide cylinder 26 and the liquid outlet pipe 22 rotate in opposite directions respectively, wherein the liquid outlet pipe 22 is coaxially connected to the rotating shaft 225, and the outer wall of the spiral auger 2251 coaxially arranged on the rotating shaft 225 contacts the inner wall of the guide cylinder 26, so that the mixed liquid surface of the ethyl lipoic acid hydrolyzate and the acidified liquid is transported into the guide cylinder 26;

[0070] Because a plurality of through holes 261 are provided on the outer wall of the guide cylinder 26, the mixture of the ethyl thioctic acid hydrolyzate and the acidified liquid is continuously dispersed into the ethyl thioctic acid hydrolyzate at different depths during the downward conveying process of the spiral auger 2251, thereby providing an acidified environment for the rapid hydrolysis of the ethyl thioctic acid hydrolyzate. Meanwhile, the spiral stirrer 263 on the outer wall of the guide cylinder 26 rotates upward in the opposite direction to the spiral auger 2251, thereby preventing the ethyl thioctic acid hydrolyzate from being easily exchanged with the ethyl thioctic acid hydrolyzate at different depths during the stirring process.

[0071] At the same time, the liquid outlet pipe 22 is coaxially connected to the rotating shaft 225 through the mounting block 222 and the mounting cylinder 224, wherein a group of sliding rods 2221 on the mounting block 222 slide in the mounting cylinder 224, and the diameter of the limit block 2222 fixedly connected to the sliding rod 2221 is larger than the diameter of the sliding limit hole on the mounting cylinder 224, and the mounting cylinder 224 is coaxially fixedly connected to the rotating shaft 225, so that when the liquid outlet pipe 22 rotates, the rotating shaft 225 rotates accordingly, and does not affect the up and down movement relationship between the rotating shaft 225 and the liquid outlet pipe 22;

[0072] By adjusting the tilt angle of the rotating adjustment disk 31 in advance according to the required oscillation amplitude of the ethyl lipoic acid ester hydrolyzate and the acidified liquid, the hand wheel 41 is rotated so that the adjusting screw 4 is matched with the thread of the threaded mounting hole on the top of the reactor 1, so that the adjusting screw 4 pushes or pulls the rotating adjustment disk 31;

[0073] Since the eccentric shaft 227 set at an eccentric position on the connecting disk 226 coaxially fixedly connected on the rotating shaft 225 is set in the annular limit guide groove 311 on the rotating adjustment disk 31, optionally, a limit roller is provided between the eccentric shaft 227 and the annular limit guide groove 311, and the limit roller is set in the annular limit guide groove 311 and can roll, thereby reducing the friction damage between the eccentric shaft 227 and the rotating adjustment disk 31. When adjusting the inclination angle between the rotating adjustment disk 31 and the mounting frame 3, as the rotating shaft 225 rotates, there is a distance difference between the eccentric shaft 227 and the rotating adjustment disk 31.

[0074] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
