Description

Technical Field

[0001] The utility model relates to the technical field of hydrolysis devices, in particular to a hydrolysis device for xylose production. Background Art

[0002] Xylitol is an organic compound native to Finland. It is a natural sweetener extracted from plant materials such as birch, oak, corn cobs, and bagasse. During the hydrolysis process of hemicellulose to produce xylose, the heating method is to pass steam into the hydrolysis pot to directly heat the raw material liquid.

[0003] After searching, for example, a utility model patent with Chinese patent number CN219816241U discloses a hydrolysis device for producing xylose, which discharges steam through an aeration plate. Under the reaction force of the steam discharge, the aeration plate drives the connecting pipe to rotate. At the same time, the aeration plate also plays the function of stirring the material in the circular motion, so that the material is heated more evenly. However, when the device discharges steam, since the position of the gas outlet component is fixed at the bottom of the hydrolysis pot, the device can only exhaust gas at the bottom of the hydrolysis pot, which will still cause the local temperature to be too high, the temperature distribution is uneven, and it is easy to cause excessive hydrolysis side reactions, and finally lead to poor quality of the hydrolyzate, affecting the yield and quality of xylose. Therefore, a hydrolysis device for xylose production is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 In this embodiment, a hydrolysis device for xylose production includes a hydrolysis pot 1, a pot cover 2 is installed on the top of the hydrolysis pot 1, a steam inlet pipe 3 is arranged between the pot cover 2 and the hydrolysis pot 1, and an adjustment mechanism 4 is arranged between the steam inlet pipe 3 and the pot cover 2.

[0024] Specifically, a threaded sleeve 402 is rotatably connected to the mounting shell 401, a motor 403 is fixedly mounted on the top of the pot cover 2, a rotating rod 404 is fixedly mounted at the output shaft of the motor 403, a driving gear 405 is fixedly mounted on the outside of the rotating rod 404, a passive gear 406 is fixedly mounted on the outside of the threaded sleeve 402, and a thread 407 is provided on the outer wall of the steam inlet pipe 3. By setting the adjustment mechanism 4, after the steam is discharged into the steam inlet pipe 3, the rotating rod 404 and the driving gear 405 can be driven to rotate by controlling the motor 403, and the passive gear 406 and the threaded sleeve 402 are driven to rotate under the meshing of the driving gear 405 and the passive gear 406. Since the threaded sleeve 402 is threadedly connected to the steam inlet pipe 3, the steam inlet pipe 3 can be driven to move up and down and rotate, so that the annular pipe 7 can be driven to move up and down for exhaust, so as to achieve more uniform exhaust. The motor 403 is controlled to rotate forward and flip to achieve the up and down movement of the annular pipe 7.

[0025] Specifically, the lower end of the steam inlet pipe 3 is provided with an outlet seat 5 for installing an outlet assembly, and a plurality of connecting air pipes 6 are fixedly installed outside the outlet seat 5 . The steam in the steam inlet pipe 3 enters the connecting air pipes 6 through the outlet seat 5 .

[0026] Specifically, an annular tube 7 is disposed outside the gas outlet seat 5 , and the gas outlet seat 5 and the annular tube 7 are connected to a connecting gas pipe 6 , and steam enters the annular tube 7 through the connecting gas pipe 6 .

[0027] Specifically, the outer wall of the ring tube 7 is provided with a plurality of air outlets, which are evenly distributed on the outer wall of the ring tube 7. Steam is evenly discharged into the solution through the air outlets on the ring tube 7 to prevent steam from being discharged from a local position, causing uneven temperature.

[0028] Specifically, a feed pipe 8 is provided at the bottom of the hydrolysis pot 1, a pipe connector 9 is installed at the top of the steam inlet pipe 3, and a plurality of stirring plates 10 are fixedly installed outside the steam inlet pipe 3. The hydrolyzed solution is discharged through the feed pipe 8, and the external pipe is connected to the pipe connector 9. During the exhaust process, the stirring plate 10 rotates along with the rotation of the steam inlet pipe 3 to fully stir the solution.

[0029] When implementing, follow these steps:

[0030] 1) First, the external exhaust pipe is connected to the steam inlet pipe 3 through the pipe connector 9. After ventilation, the steam will enter the steam inlet pipe 3 and be discharged into the hydrolysis pot 1 through the outlet on the ring pipe 7 to heat the raw material liquid;

[0031] 2) Then the motor 403 is controlled to rotate forward, driving the rotating rod 404 and the driving gear 405 to rotate, driving the driven gear 406 and the threaded sleeve 402 to rotate, driving the steam inlet pipe 3 to move upward, so as to drive the annular pipe 7 to spray steam upward;

[0032] 3) Finally, the motor 403 is controlled to reverse to drive the ring pipe 7 to spray steam downward. During the exhaust process, the stirring plate 10 rotates along with the rotation of the steam inlet pipe 3 to stir the solution.

[0033] In summary, the xylose production hydrolysis device, by setting the regulating mechanism 4, can drive the rotating rod 404 and the driving gear 405 to rotate by controlling the motor 403 after the steam is discharged into the steam inlet pipe 3, and the driving gear 405 is meshed with the driven gear 406, so as to drive the driven gear 406 and the threaded sleeve 402 to rotate. Since the threaded sleeve 402 is threadedly connected with the steam inlet pipe 3, the steam inlet pipe 3 can be driven to move up and down and rotate, so that the annular pipe 7 can be driven to move up and down to exhaust, and more uniform exhaust can be achieved. By controlling the motor 403 to rotate forward and flip, the annular pipe 7 can be moved up and down, which solves the problem that the comparative device can only exhaust at the bottom of the hydrolysis pot because the position of the gas outlet component is fixed at the bottom of the hydrolysis pot, which still causes the local temperature to be too high, the temperature distribution is uneven, and it is easy to cause excessive hydrolysis side reactions, and finally leads to poor quality of the hydrolyzate, affecting the yield and quality of xylose.
