[0029] 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.

[0030] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a high-efficiency liquid phase mobile phase preparation device with an ultrasonic dissolution module, comprising a base 1 and a synchronous belt 10, a preparation barrel 3 is fixedly connected to the top of the base 1, a barrel cover 4 is arranged on the top of the preparation barrel 3, a hollow column 5 is rotatably connected to the middle of the inner top of the barrel cover 4, a first rotating rod 6 is rotatably connected to the left side of the bottom of the barrel cover 4, a servo motor 7 is fixedly connected to the right side of the top of the barrel cover 4, an output end of the servo motor 7 passes through the barrel cover 4 and is fixedly connected to a second rotating rod 8, the second rotating rod 8, the hollow column 5 and the outer middle and upper parts of the first rotating rod 6 are fixedly connected to synchronous wheels 9, and multiple synchronous wheels 9 are connected to each other. The barrel 3 is connected to the preparation barrel 3 by a synchronous belt 10 for transmission. A plurality of stirring rods 11 are fixedly connected to the outer sides of the second rotating rod 8, the hollow column 5 and the first rotating rod 6 at equal intervals. An ultrasonic generator 12 is fixedly connected to the middle of the top of the barrel cover 4. The output end of the ultrasonic generator 12 passes through the barrel cover 4 and is arranged inside the hollow column 5. A cleaning mechanism 2 is arranged on the inner side of the preparation barrel 3. The stirring rods 11 on the outer sides of the hollow column 5, the first rotating rod 6 and the second rotating rod 8 are staggered with each other. A liquid inlet 15 is connected to the front side of the top of the barrel cover 4. A liquid outlet 13 is connected to the bottom end of the preparation barrel 3. The bottom end of the liquid outlet 13 passes through the base 1 and is threadedly connected to a sealing cover 14.

[0031] Specifically, the servo motor 7 can drive the second rotating rod 8 to rotate. As the second rotating rod 8 rotates, the synchronous wheel 9 on the outside thereof also rotates rapidly. The synchronous wheel 9 on the outside of the first rotating rod 6 and the hollow column 5 will also rotate via the synchronous belt 10, so that the stirring rods 11 on the outside of the first rotating rod 6, the hollow column 5 and the second rotating rod 8 can also rotate. The rotation of these stirring rods 11 can stir and dissolve the sample inside the preparation barrel 3 efficiently and evenly, and the high-frequency vibration generated by the start-up of the ultrasonic generator 12 can further accelerate the dissolution process of the sample. This ultrasonic-assisted dissolution method can achieve the expected dissolution and preparation effect in a shorter time, greatly improve the operating efficiency of the equipment, and thus reduce the operating cost of the equipment.

[0032] Reference Figure 2 and Figure 3 The cleaning mechanism 2 includes a gear 201, which is fixedly connected to the outer side of the second rotating rod 8. The inner side of the barrel cover 4 is rotatably connected to a hollow gear ring 202, which is meshed with the gear 201. The four corners of the bottom of the hollow gear ring 202 are fixedly connected to arc scrapers 203, and the bottom ends of the multiple arc scrapers 203 are fixedly connected to the same cross scraper 204;

[0033] Specifically, when the second rotating rod 8 rotates, the gear 201 on its outer side will also rotate accordingly, and the hollow gear ring 202 will rotate synchronously due to meshing with the gear 201, and the rotation of the hollow gear ring 202 further drives the rotation of the arc scraper 203, thereby achieving all-round scraping of the inner wall of the preparation barrel 3. This design not only ensures the thoroughness of the scraping work, but also greatly improves the work efficiency. The cross scraper 204 at the bottom of the arc scraper 203 will also rotate, specifically responsible for scraping the inner bottom of the preparation barrel 3. This double scraping design ensures that every corner of the inner wall of the preparation barrel 3 can be thoroughly cleaned, thereby avoiding the problem of sample residue. This innovative design not only simplifies the work process of the staff to clean the inner wall of the preparation barrel 3, but also greatly improves the practicality and reliability of the device.

[0034] Reference Figure 1 A controller 17 is fixedly connected to the left side of the preparation barrel 3, and the controller 17 is electrically connected to the servo motor 7 and the ultrasonic generator 12 respectively. A protective cover 18 is provided on the outside of the controller 17, and one side of the protective cover 18 is rotatably connected to the left side of the preparation barrel 3;

[0035] Specifically, the operation of the servo motor 7 and the ultrasonic generator 12 can be controlled by the controller 17 , and the protective cover 18 can protect the controller 17 from being damaged by external factors.

[0036] Reference Figure 1 and Figure 2 The left and right sides of the barrel cover 4 are both threadedly connected with bolts 16, and one end of the bolt 16 passes through the barrel cover 4 and the preparation barrel 3 in sequence;

[0037] Specifically, loosening the bolts 16 can release the limit fixation of the barrel cover 4, and then the barrel cover 4 can be removed to inspect and maintain the structure at its bottom.

[0038] Reference Figure 1 , an observation window 19 is provided in the middle of the front side of the preparation barrel 3;

[0039] Specifically, the observation window 19 can facilitate the staff to check the internal situation of the preparation barrel 3 at any time, and can respond in time when encountering special situations.

[0040] Working principle: When using the device, first pour the sample to be dissolved into the preparation barrel 3 through the liquid inlet 15, and then the servo motor 7 can drive the second rotating rod 8 to rotate, and the synchronous wheel 9 on the outside thereof will rotate accordingly, and the synchronous wheel 9 on the outside of the first rotating rod 6 and the hollow column 5 will also rotate through the synchronous belt 10. At this time, the stirring rod 11 on the outside of the first rotating rod 6, the hollow column 5 and the second rotating rod 8 will rotate to stir and dissolve the sample in the preparation barrel 3. At the same time, starting the ultrasonic generator 12 can further improve the dissolution effect of the sample, and can achieve the expected dissolution preparation effect in a shorter time, thereby reducing the operating cost of the equipment. To meet the needs of users, when the second rotating rod 8 rotates, the gear 201 on its outer side will rotate accordingly, and the hollow gear ring 202 will also rotate accordingly due to the engagement with the gear 201, thereby driving the arc scraper 203 to rotate to scrape the inner wall of the preparation barrel 3, and the cross scraper 204 at the bottom of the arc scraper 203 will also rotate to scrape the bottom of the inner side of the preparation barrel 3, which can prevent the sample from remaining on the inner wall of the preparation barrel 3 and affecting the subsequent work. It is relatively simple for the staff to clean the inner wall of the preparation barrel 3, thereby improving the practicality of the device. After the preparation work is completed, the sealing cover 14 is opened and the prepared sample can be collected through the liquid outlet 13.
