Abstract
Description
Technical Field
[0001] This invention relates to the field of protease hydrolysis technology, and more particularly to a microwave-assisted protease hydrolysis device. Background Technology
[0002] Microwave-assisted protein hydrolysis devices use microwave energy to achieve sample hydrolysis. Under the action of microwave radiation, the molecules inside the protein sample rapidly vibrate violently, leading to sample decomposition. It is suitable for processing different types of protein samples. Currently, the hydrolysis vessel containing the sample is installed on a tray inside the hydrolysis device before the hydrolysis operation is performed. Different sizes of hydrolysis vessels are used for different protein samples. However, when a smaller hydrolysis vessel is placed on the tray for hydrolysis, the vessel may tilt, resulting in uneven distribution of the protein sample inside the vessel. This causes some samples to overheat during microwave heating, while other parts remain underheated, reducing the hydrolysis effect and affecting the accuracy and reliability of the experiment.

[0013] By employing the above technical solution, the present invention provides a microwave-assisted proteolytic enzyme digestion device, which, compared with the prior art, has at least the following beneficial effects: 1. This invention uses a positioning component to simultaneously clamp multiple enzymatic digestion vessels placed on a sample tray. The digestion vessels have through holes that contact the top of the lower tray. A rotating component synchronously drives the telescopic clamping components of the first and second annular disks, thereby simultaneously fixing the digestion vessels.

[0014] 2. This invention uses a rotating assembly to drive multiple active gear rings on the lower tray to rotate simultaneously. A driving cylinder moves a movable rack, causing the driving gear ring and transmission gear ring to rotate simultaneously. The transmission gear ring drives multiple active gear rings to rotate, which in turn drives the driven gear ring to rotate via a connecting vertical rod. In use, multiple enzymatic hydrolysis vessels are first placed on the sample tray and then fixed directly, ensuring the consistency of simultaneous fixing of multiple enzymatic hydrolysis vessels, improving the convenience of fixing multiple enzymatic hydrolysis vessels, enhancing the practicality of the enzymatic hydrolysis device, and making it more convenient to use.
[0015] 3. The present invention clamps and fixes both ends of the enzymatic hydrolysis vessel by setting a telescopic clamping component. The active toothed ring and the driven toothed ring synchronously drive multiple clamping heads on the inner side of the first and second annular disks on the same vertical axis to move. The multiple clamping heads clamp the enzymatic hydrolysis vessel at the same time, keeping it stable and fixed in the vertical direction, effectively preventing the enzymatic hydrolysis vessel from tilting, ensuring that no unnecessary vibration or displacement occurs during the heating process, and reducing safety hazards under high pressure operation.
[0016] 4. This invention provides a limiting effect on the rotation of the active and driven toothed rings by opening an arc-shaped groove 1 on the top of the annular shell on the lower tray and an arc-shaped groove 2 on the top of the upper tray. The upper and lower ends of the connecting vertical rod pass through the arc-shaped groove 1 and the arc-shaped groove 2 respectively, allowing the connecting vertical rod to rotate within a certain range.

[0019] 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.
[0020] First Embodiment The purpose of microwave-assisted protein hydrolysis is to achieve a more uniform heat distribution during microwave treatment, which helps reduce sample sintering and contamination, and improves the accuracy and reliability of the analysis. However, because different protein samples use different sizes of hydrolysis vessels, smaller vessels tend to tilt during the hydrolysis process as they rotate with the tray. This tilting can cause uneven distribution of the protein sample within the vessel, affecting the accuracy of the hydrolysis results. To ensure greater stability of each hydrolysis vessel during hydrolysis and avoid uneven microwave heating caused by tilting, such as... Figure 1 - Figure 4As shown, this embodiment provides a microwave-assisted enzymatic hydrolysis device, which consists of a box 1, a sample tray 2, and a positioning component 3. The box 1 is a microwave enzymatic hydrolysis box, which is equipped with multiple sets of magnetrons for heating and activating the enzymatic hydrolysis reaction. The sample tray 2 is located inside the box 1 for simultaneously placing multiple enzymatic hydrolysis vessels for enzymatic hydrolysis operations.
[0021] The sample tray 2 consists of an upper tray 21 and a lower tray 22 spaced apart. The upper tray 21 and the lower tray 22 are fixedly connected by multiple supporting vertical rods. A rotating ring 23 is fixed at the bottom of the lower tray 22 and rotates on the inner bottom wall of the box 1. A motor fixed to the box 1 is also installed at the bottom axis of the lower tray 22. During the protein hydrolysis process, the motor in the microwave hydrolysis box drives the lower tray 22 and the upper tray 21 to rotate simultaneously, thereby driving the hydrolysis tank to rotate, which enhances the contact between the protein sample and the enzyme and solution, promotes the mixing of reactants, and improves the reaction efficiency of protein hydrolysis.
[0022] To ensure that each sample reacts under the same conditions and reduce experimental errors caused by uneven heating of the samples, a positioning component 3 is provided on the sample tray 2 to simultaneously clamp and stabilize multiple enzymatic digestion vessels. The positioning component 3 includes multiple first annular disks 30 set on the upper tray 21, multiple second annular disks 31 set on the lower tray 22, and multiple circular holes 32 opened on the upper tray 21. The first annular disks 30 are located at the top of the circular holes 32. During enzymatic digestion, the enzymatic digestion vessels extend through the circular holes 32 to contact the top of the lower tray 22. An active toothed ring 33 is rotatably arranged on the outer side of the second annular disks 31 on the top of the lower tray 22, and a driven toothed ring 34 is rotatably arranged on the outer side of the first annular disks 30 on the top of the upper tray 21. A connecting vertical rod 35 fixed to the top of the active toothed ring 33 and fixed to the driven toothed ring 34 is fixed.
[0023] In this design, annular shells 38 are fixedly installed on both the first annular disk 30 and the second annular disk 31. The top of the annular shell 38 on the lower tray 22 is provided with an arc-shaped groove 39. The connecting vertical rod 35 passes through the arc-shaped groove 39 and is slidably connected to it. The top of the upper tray 21 is provided with multiple arc-shaped grooves arranged in a circular array. The connecting vertical rod 35 passes through the arc-shaped grooves 39 and 39 and is slidably connected to them. The upper and lower ends of the connecting vertical rod 35 pass through the arc-shaped grooves 39 and 39 and 34 respectively. The active gear ring 33 drives the driven gear ring 34 to rotate through the connecting vertical rod 35, so that the connecting vertical rod 35 rotates within a certain range. The maximum rotation angle of the active gear ring 33 is 74°, thereby providing a limiting effect on the rotation of the active gear ring 33 and the driven gear ring 34.
[0024] Second Embodiment To ensure consistency in the simultaneous fixation of multiple enzymatic hydrolysis vessels and to make the fixation of multiple enzymatic hydrolysis vessels more convenient, such as... Figure 5As shown, in this embodiment, a rotating assembly 36 is provided on the lower tray 22 to drive the synchronous rotation of multiple active gear rings 33 on the second annular disks 31. Specifically, the rotating assembly 36 includes a transmission gear ring 361 rotatably disposed on the top of the lower tray 22. The transmission gear ring 361 is meshed with multiple active gear rings 33 on the top of the lower tray 22. The multiple active gear rings 33 are divided into inner and outer layers on the lower tray 22. Both the inner and outer sides of the transmission gear ring 361 are meshed with the active gear rings 33. Multiple circumferentially arrayed limiting arc grooves 362 are provided on the lower tray 22. The inner side of the limiting arc grooves 362 is slidably disposed. A connecting block 363 is provided. The bottom of the lower tray 22 is provided with a drive gear ring 364 that is fixed to multiple connecting blocks 363. The drive gear ring 364 drives the connecting blocks 363 to rotate inside the limiting arc groove 362. The maximum rotation angle of the connecting blocks 363 is 116°. The connecting blocks 363 drive the transmission gear ring 361 to rotate. The transmission gear ring 361 simultaneously drives multiple active gear rings 33 to rotate at a certain angle. A movable rack 365 that slides with the bottom of the lower tray 22 is meshed on one side of the drive gear ring 364. A drive cylinder 366 whose output end is fixed to the movable rack 365 is fixedly embedded in the bottom of the lower tray 22.
[0025] By activating the drive cylinder 366, the movable rack 365 is driven to move. The movable rack 365 drives the drive gear ring 364, which meshes with it, to rotate. The drive gear ring 364 drives the transmission gear ring 361 to rotate through the connecting block 363. The transmission gear ring 361 drives multiple active gear rings 33 to rotate synchronously, thereby ensuring the consistency of synchronously fixing multiple enzymatic hydrolysis tanks and improving the convenience of fixing multiple enzymatic hydrolysis tanks.
[0026] Third Embodiment To prevent the enzymatic hydrolysis vessel from tilting during enzymatic hydrolysis and to ensure that no unnecessary vibration or displacement occurs during heating, such as... Figure 6As shown, in this embodiment, telescopic clamping components 37 for clamping and fixing the two ends of the enzymatic hydrolysis vessel are respectively provided on the first annular disk 30 and the second annular disk 31. The telescopic clamping component 37 on the upper tray 21 is driven by the driven toothed ring 34, and the telescopic clamping component 37 on the lower tray 22 is driven by the driving toothed ring 33. The two ends of the enzymatic hydrolysis vessel are clamped and fixed by the telescopic clamping components 37 on the first annular disk 30 and the second annular disk 31. This method can be applied to enzymatic hydrolysis vessels of different specifications, thus expanding the applicability of the enzymatic hydrolysis device. Specifically, the telescopic clamping component 37 includes components respectively disposed in the first annular disk 30 and the second annular disk 31. Multiple circumferentially arrayed clamping heads 371 are arranged on the side. One end of each clamping head 371 is integrally formed with an anti-slip soft pad 377. The anti-slip soft pad 377 contacts the enzymatic hydrolysis vessel, increasing the contact friction between the clamping head 371 and the enzymatic hydrolysis vessel, making the enzymatic hydrolysis vessel more stable. The inner side of each clamping head 371 is provided with a threaded shaft 372. The threaded shaft 372 on the first annular disk 30 passes through the side wall of the first annular disk 30 and is rotatably connected to it through a bearing. The threaded shaft 372 on the second annular disk 31 passes through the side wall of the second annular disk 31 and is rotatably connected to it through a bearing. The threaded shaft 372 is threaded with a threaded seat 373 that is fixed to the clamping head 371.
[0027] Multiple circumferentially arranged limiting grooves 374 are provided on both the first annular disk 30 and the second annular disk 31. A limiting slider 375 fixed to the pressing head 371 is slidably arranged on the inner side of the limiting groove 374. The pressing head 371 drives the limiting slider 375 to move inside the limiting groove 374, thereby improving the stability of the pressing head 371's movement. Multiple circumferentially arranged transmission gears 376 are respectively meshed on the top of the active gear ring 33 and the driven gear ring 34. When the active gear ring 33 and the driven gear ring 34 rotate at a certain angle, the transmission gears 376 can rotate multiple times, thereby driving the pressing head 371 to make linear movement through the threaded seat 373. The transmission gears 376 are fixedly connected to the end of the threaded shaft 372 away from the pressing head 371, maintaining the stability of the enzymatic hydrolysis tank in the vertical direction and effectively preventing the enzymatic hydrolysis tank from tilting.
[0028] This invention uses a rotating component 36 to drive multiple active toothed rings 33 on the lower tray 22 to rotate simultaneously. At the same time, it works in conjunction with a telescopic clamping component 37 to clamp and fix both ends of the enzymatic hydrolysis vessel. This simultaneously clamps multiple enzymatic hydrolysis vessels placed on the sample tray 2, ensuring the stability of each enzymatic hydrolysis vessel during enzymatic hydrolysis. This avoids uneven microwave heating caused by the tilting of the enzymatic hydrolysis vessel, improves the reliability and accuracy of experimental results, and expands the applicability of the enzymatic hydrolysis device.
[0029] During use, multiple enzymatic digestion vessels containing protein samples are placed on sample tray 2. The digestion vessels extend through the circular hole 32 to contact the top of the lower tray 22. Then, the drive cylinder 366 is activated. The output end of the drive cylinder 366 pulls the movable rack 365 to move. The movable rack 365 drives the drive gear ring 364 meshing with it to rotate. The drive gear ring 364 drives the connecting block 363 on it to rotate inside the limiting arc groove 362. The connecting block 363 drives the transmission gear ring 361 to rotate. The transmission gear ring 361 drives multiple active gear rings 33 to rotate synchronously.
[0030] Simultaneously, the drive gear drives the connecting vertical rod 35 to rotate. Since the upper and lower ends of the connecting vertical rod 35 pass through the arc-shaped groove 39 and the arc-shaped groove 2 respectively, the connecting vertical rod 35 drives the driven gear ring 34 at its top to rotate. The drive gear and the driven gear ring 34 rotate simultaneously. The drive gear and the driven gear ring 34 drive the transmission gear 376 meshing with them to rotate. The transmission gear 376 drives the threaded shaft 372 at its axis to rotate. The threaded shaft 372 drives the clamping head 371 to move towards the enzymatic hydrolysis tank through the threaded seat 373. The clamping head 371 drives the anti-slip soft pad 377 to contact the outer wall of the enzymatic hydrolysis tank, thereby simultaneously clamping and fixing multiple enzymatic hydrolysis tanks on the sample tray 2, and then performing the enzymatic hydrolysis operation.
