Description

Technical Field

[0001] This utility model relates to the field of homogenizer structure technology, and in particular to a high-pressure homogenizing device. Background Technology

[0002] A high-pressure homogenizer is a precision device that refines and homogenizes materials (such as emulsions and suspensions) through fluid shearing, impact, and cavitation under high pressure. It is widely used in industries such as food and beverage, biopharmaceuticals, chemicals, and cosmetics. Its core principle is to utilize the synergistic effect of a high-pressure pumping system and homogenizing valve components to achieve microstructural modification of the material.

[0003] High-pressure homogenizers are commonly used in the pharmaceutical and food industries. In the pharmaceutical industry, there are strict requirements for the particle size of the drug solution. To ensure that the particle size of the drug solution meets the process requirements in the shortest possible time, it is generally necessary to ensure that all drug solutions are homogenized the same number of times during the circulating homogenization process. In existing high-pressure homogenizers, the homogenized drug solution is directly returned to the homogenization device during the circulating homogenization process, mixing with the unhomogenized drug solution. This makes it impossible to ensure that all drug solutions are homogenized the same number of times, thus increasing the overall homogenization time. To address the above problems, this utility model provides a solution. Utility Model Content

The crankshaft 3 is mounted inside the homogenizer body 1 via bearings. The motor 2 is connected to the crankshaft 3 via the transmission mechanism. The two ends of the crankshaft connecting rod 4 are hinged to the crankshaft 3 and the plunger rod 5, respectively. One end of the plunger rod 5... The piston 6 is fixedly connected to the plunger 7. The inlet check valve 10 is installed at the inlet of the plunger 7. The homogenizing valve 11 is installed at the outlet on the side wall of the plunger 7. The homogenizing tank 15 is connected to the inlet of the plunger 7 through the inlet pipe 16. The temporary storage tank 13 is connected to the outlet 29 of the homogenizing valve 11 through the outlet pipe 12. The temporary storage tank 13 is connected to the homogenizing tank 15 through a pipeline and a circulation pump 14. A level gauge 30 is installed inside the homogenizing tank 15. The liquid inlet check valve 10 includes an inlet valve block 19, an inlet spring 20, and an inlet valve seat 21. The inlet valve seat 21 is fixedly installed in the plunger cavity 7, and a through hole for liquid passage is provided in the middle of the inlet valve seat 21. The two ends of the inlet spring 20 are fixedly connected to the inlet valve seat 21 and the inlet valve block 19, respectively, and the inlet spring 20 pushes the inlet valve block 19 to fit and seal with the inlet valve port. The homogenizing valve 11 includes a homogenizing valve block 22, a homogenizing spring 23, and a homogenizing valve seat 24. The system includes a homogenizing chamber 25 and a homogenizing valve core 26. The homogenizing valve seat 24 is fixedly installed inside the homogenizing chamber 25. The two ends of the homogenizing spring 23 are respectively connected to the homogenizing valve block 22 and the homogenizing valve seat 24. The homogenizing spring 23 pushes the homogenizing valve block 22 to fit and seal with the homogenizing valve port. The homogenizing valve seat 24 is provided with a through hole for liquid to pass through. The homogenizing valve core 26 is installed inside the homogenizing chamber 25 through an adjusting mechanism, and a homogenizing gap is formed between the homogenizing valve core 26 and the homogenizing valve seat 24.

[0018] Furthermore, the adjustment mechanism includes an adjustment rod 27 and an adjustment frame 28. The adjustment frame 28 is installed outside the homogenizer body 1. One end of the adjustment rod 27 is fixedly connected to the homogenizing valve core 26, and the other end of the adjustment rod 27 is threaded. The threaded end of the adjustment rod 27 is threadedly engaged with the threaded hole of the adjustment frame 28.

By cooperating with the adjustment rod 27 and the adjustment frame 28, the homogenization gap between the homogenizing valve seat 24 and the homogenizing valve core 26 is adjusted, thereby changing shearing, impact, and cavitation, and thus achieving the purpose of adjusting the homogenization parameters.

[0019] Furthermore, the bottom side wall of the temporary storage tank 13 is provided with a drain pipe 17, and a valve 18 is installed on the drain pipe 17.

[0022] Working principle: The drug solution to be homogenized is added to the homogenization tank 15. The homogenization parameters are adjusted by the regulating mechanism. The motor 2 is started, and the rotating plunger rod and piston 6 move cyclically, drawing the drug solution into the plunger chamber 7. Then, it is pressurized and pushed into the homogenization chamber 25. When the high-pressure drug solution passes through the gap between the homogenization valve seat 24 and the homogenization valve core 26, shearing, impact, and cavitation occur, thereby refining the particle size. The homogenized drug solution enters the temporary storage tank 13 for temporary storage. When the drug solution in the homogenization tank 15 is low, it is detected by the level gauge 30, and the motor 2 is stopped. The circulation pump 14 is started, and the circulation pump 14 sends the drug solution in the temporary storage tank 13 back to the homogenization tank 15. When all the drug solution in the temporary storage tank 13 has been transferred, the motor 2 is started and the circulation pump 14 stops working. The above work is repeated until the drug solution reaches the required technical parameters. The drug solution is collected from the discharge pipe 17 for the next process.
