The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] For examples, please refer to Figure 1-3 This utility model provides a technical solution:
[0027] A pharmaceutical filtration and extraction tank includes an extraction tank body 1, with an inlet 2 at the top and an outlet 3 at the bottom. An extraction chamber 4 is located above the interior of the extraction tank body 1. A rotatable rotating shaft 41 is horizontally arranged inside the extraction chamber 4. Stirring blades 42 are arranged around the outside of the rotating shaft 41. A drive motor 43, located outside the extraction tank body 1, is fixedly installed on one axial side of the rotating shaft 41. A filtration chamber 5 is located below the extraction chamber 4. A first filter screen 6 and a second filter screen 7 are installed inside the filtration chamber 5 from top to bottom. A connecting plate 8 is provided on one side of the first filter screen 6 and the second filter screen 7. A baffle plate 9 is provided on the top of the connecting plate 8. A vibration motor 10 is fixedly connected to the bottom of the connecting plate 8. Spring columns 11 are vertically installed on the left and right sides of the first filter screen 6 and the second filter screen 7, and are inserted into the left and right cavities of the filter chamber 5 through the spring columns 11. A maintenance ladder 12 is fixedly installed on the outside of the extraction tank 1 to facilitate maintenance and repair of the equipment by the staff. An installation bracket 13 is fixedly installed at the bottom of the extraction tank 1 to ensure stable operation of the equipment and ensure normal operation of the equipment.
[0028] Specifically, a sealing cap is provided at the feed inlet 2. The sealing cap is connected to the feed inlet 2 by threads. A rubber sealing ring is provided on the inside of the sealing cap to seal the feed inlet 2 after feeding is completed, to prevent impurities and gas from entering, to avoid contamination of the pharmaceutical raw materials and extraction solvent, and to prevent internal gas leakage, thus maintaining a stable reaction environment inside the tank.
[0029] Specifically, the stirring blade 42 is spiral in shape with a spiral angle of 30-45 degrees. Driven by the rotating shaft 41, it can efficiently stir the pharmaceutical raw materials and extraction solvent in the extraction chamber, so that the two are fully mixed.
[0030] Specifically, the drive motor 43 is a variable frequency motor, which can change the rotation speed of the rotating shaft 41 by adjusting the motor frequency to adapt to the different stirring speed requirements of different pharmaceutical raw materials during the extraction process.
[0031] Specifically, a discharge funnel 16 is provided between the bottom of one side of the extraction chamber 4 and the internal cavity of the filter chamber 5. A baffle structure is formed between the lower part of the discharge funnel 16 and the baffle plate 9. After the extraction process is completed in the extraction chamber 4, the material enters the filter chamber 5 through the discharge funnel 16. The baffle plate 9 plays a role in blocking and guiding the material. The baffle structure formed by the discharge funnel 16 and the baffle plate 9 helps to control the flow of material, so that the material is more evenly distributed in the filter chamber 5, ensuring the subsequent filtration effect.
[0032] Specifically, the pore size of the first filter screen 6 is larger than that of the second filter screen 7. The first filter screen 6 is used to filter larger particulate impurities, and the second filter screen 7 is used to further filter smaller particles, thus achieving multi-stage precision filtration. The material is filtered starting from the first filter screen 6. Large particulate impurities are intercepted by the first filter screen 6, while smaller particles continue to pass through the second filter screen 7 for secondary filtration.
[0033] Specifically, the vibration motor 10 is connected to a timer, which can set the vibration time and interval of the vibration motor 10 to vibrate the first filter screen 6 and the second filter screen 7 at regular intervals, so as to prevent the filter screens from clogging and improve the filtration efficiency.
[0034] Specifically, the spring column 11 includes a spring and a column body. The spring is located inside the column body, and both ends of the spring are fixedly connected to the end of the column body and the sides of the first filter screen 6 and the second filter screen 7, respectively. When the vibration motor 10 is working, the spring column 11 plays the role of buffering and enhancing the vibration effect.
[0035] Specifically, two filter replacement slots 14 are provided on the outer side of the extraction tank 1 and on the outer surface of the filter chamber 5. The first filter 6 and the second filter 7 are inserted into the filter chamber 5 through the filter replacement slots 14. Handles 15 are also fixedly installed on the outer side of the first filter 6 and the second filter 7. When it is necessary to replace the first filter 6 or the second filter 7, the filter is pulled out from the filter replacement slot 14 through the handle 15 and a new filter is installed.
[0036] The working process of this utility model is as follows: When using the drug filtration and extraction tank, the drug raw materials and extraction solvent are first added to the extraction chamber 4 inside the extraction tank 1 through the feed inlet 2. After feeding, the sealing cap with a rubber sealing ring is screwed onto the feed inlet 2 to prevent impurities from entering and gas from leaking. Then, the drive motor 43 is started, which drives the rotating shaft 41 to rotate, causing the stirring blades 42 with a spiral angle of 30-45 degrees on the outside of the rotating shaft 41 to rotate, stirring the drug raw materials and extraction solvent in the extraction chamber. According to the characteristics of the drug raw materials, the frequency of the drive motor 43 is adjusted to change the rotation speed of the rotating shaft 41, promoting the full mixing of the drug raw materials and extraction solvent to complete the extraction process. After extraction, the material enters the filter chamber 5 through the discharge funnel 16 between the bottom of one side of the extraction chamber 4 and the filter chamber 5. The baffle plate 9 blocks and guides the material, making the material more evenly distributed in the filter chamber 5. The material first passes through the first filter screen 6, where large particles of impurities are intercepted, and smaller particles continue to pass through the second filter screen 7 for secondary filtration. The vibration motor 10 is connected to a timer, which starts according to the set vibration time and interval, driving the connecting plate 8 to vibrate, which in turn causes the first filter screen 6 and the second filter screen 7 to vibrate. The spring column 11 enhances the vibration effect and acts as a buffer to prevent the filter screen from clogging, ensuring continuous and efficient filtration. The filtered extract flows out from the outlet 3. If the first filter screen 6 or the second filter screen 7 needs to be replaced, the filter screen is pulled out from the filter screen replacement slot 14 through the handle 15 and a new filter screen is installed. Workers can climb to the extraction tank 1 via the maintenance ladder 12 to perform maintenance and repair work, while the mounting bracket 13 stably supports the extraction tank 1 on the ground.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
