Description

Technical Field

[0001] The invention relates to the technical field of concentration tanks, in particular to a silymarin concentration tank. Background Art

[0002] The silymarin concentration tank is a special equipment for concentrating silymarin extract. The silymarin concentration tank is mainly used to concentrate the silymarin extract to improve its concentration and purity. The solvent in the extract is evaporated by heating and reducing pressure to concentrate silymarin. At the same time, the concentration tank is usually equipped with an agitator. During the concentration process, the agitator plays a key role. It can ensure that the solution is evenly mixed in the tank to avoid local overheating or uneven concentration, thereby improving the concentration efficiency and the quality of silymarin.

[0003] However, when the existing silymarin concentration tank is in use, bubbles are easily generated during the concentration process, thereby affecting the efficiency and effect of the concentration. After the concentration is completed, solid impurities are easily accumulated at the bottom, which is not convenient for cleaning and collection. At the same time, the extract is easily left on the inner wall of the concentration tank and the agitator, and the extract will also remain in the solid impurities, causing waste and affecting the concentration effect.

[0059] Compared with the prior art, the present invention has the following beneficial effects:

[0060] (1) The silymarin concentration tank is provided with a defoaming mechanism, etc., so that when the concentration is performed, the extract is firstly fed into the concentration tank body through the feed valve, and then the extract in the concentration tank body is heated and concentrated, so that the organic solvent is converted into steam and then discharged and collected through the steam valve after passing through the first telescopic tube and the electromagnetic valve. At the same time, the motor is started, and the rotation of the motor drives the rotation of the gear, thereby driving the gear ring and the rotating column to rotate, and then driving the rectangular tube to rotate through the first connecting plate, so that the extract in the concentration tank body can be stirred, and the efficiency and quality of the concentration can be improved. At the same time, when the rectangular tube rotates, the bubbles on the liquid surface can pass through the gap between the two rectangular tubes, and under the action of the conical block, the bubbles can be broken, and the conical block is provided in multiple groups, and the defoaming effect can be achieved at different liquid level heights, thereby improving the efficiency and quality of the concentration.

[0061] (2) The silymarin concentration tank is provided with a lifting mechanism and a first driving mechanism. After the concentration is completed, the electromagnetic valve is closed and the discharge valve is opened. The concentrated silymarin extract with a high concentration can reach the filter cloth through the hollow plate for filtration. The filtered silymarin extract is collected through the extract collection tank. At the same time, the cylinder is started to move the connecting block downward, and the moving plate is driven to move downward through the second moving rod. When the moving plate moves downward, the rotating rod and the scraper can be driven downward through the first reset mechanism, and the conical cover can be driven to move downward synchronously through the second reset mechanism. When the moving plate and the conical cover are against the side wall of the conical block, the conical block and the sliding rod can be pushed to move into the rectangular tube. At the same time, the first elastic member is The conical cover is compressed to ensure that the moving disk and the conical cover can normally pass over the conical block. At this time, the conical cover can be used to scrape and clean the inner wall of the concentration tank body and the residual silymarin on the surface of the rectangular tube to avoid waste. At the same time, the cleaning is more convenient and quick. At the same time, the liquid can be squeezed to improve the efficiency and effect of filtration, thereby improving the efficiency and effect of concentration. When the conical cover is about to move to the bottom of the concentration tank body, the cylinder is stopped. After the liquid in the concentration tank body is completely discharged, the cylinder is started again to make the moving disk and the conical cover continue to move downward. When the scraper contacts the conical surface, the bottom of the rectangular tube is just flush with the bottom of the conical cover. When the moving disk continues to move downward, the fourth elastic member is gradually compressed. At the same time, the fixed plate drives the pusher The movable pin slides along the spiral groove, thereby driving the rotating rod and the scraper to rotate, and can scrape the solid impurities remaining on the conical surface and gather them at the center position of the bottom of the conical surface. After the rotation is completed, the scraper can be aligned with the strip opening again. When the movable disk continues to move downward, the pushing pin can move downward along the vertical groove. At this time, the fixed plate is abutted against the top of the conical cover, thereby pushing the conical cover to move downward. At the same time, the fifth elastic member is compressed. At this time, the scraper can move into the strip opening, so that the solid impurities can be squeezed through the conical cover, which can improve the collection effect of silymarin extract and avoid waste. After the extrusion is completed, the third moving rod and the U-shaped frame are driven to move through the second moving module, thereby driving the collection The collecting box moves, thereby moving the impurity collecting tank to the bottom of the discharge valve, and then, the first moving rod is driven to move by the first moving module, and the baffle is driven to move. At this time, the second moving plate can be pushed to move, and the first moving plate is driven to move by the third elastic member. The second elastic member is gradually compressed. At this time, the solid impurities on the filter cloth can be pushed onto the baffle. When the baffle moves to the bottom of the hollow plate, the second elastic member is no longer compressed. When the baffle continues to move, it can push the second moving plate to move in the direction close to the first moving plate. At the same time, the third elastic member is gradually compressed, so that the filter cloth can be squeezed to squeeze out the residual silymarin extract inside it to avoid waste. After the baffle passes over the hollow plate,The solid impurities at the bottom of the concentration tank body can be discharged through the discharge valve after passing through the hollow plate. Then, the lifting mechanism drives the movable plate to move upward and reset, and the fourth elastic member gradually resets. At this time, the conical cover can gradually move upward under the action of the fifth elastic member. At this time, the push pin moves upward along the vertical groove. When the scraper is exposed from the strip opening, the fixed plate is separated from the top of the conical cover, and the fifth elastic member is reset. When the movable plate continues to move upward, it can push the pin to move upward along the spiral groove, thereby pushing the rotating rod and the scraper. At this time, the conical cover and the bottom of the conical surface can be scraped and cleaned again, and guided to the top of the hollow plate for discharge, avoiding the residue of solid impurities and ensuring the collection effect.

[0062] (3) The silymarin concentrate tank is provided with a blower mechanism, etc., so that when extrusion is performed, the conical cover can move downward along the side wall of the scraper. At the same time, the fixed cover is driven to move downward by the second connecting plate. At this time, the lower end of the conical rod abuts against the top of the scraper, so that negative pressure is generated in the fixed cover. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, external air can enter the fixed cover through the air supply pipe for temporary storage. After the extrusion is completed, when the movable plate moves upward, the conical cover can gradually move upward along the side wall of the scraper. At the same time, the fixed cover is driven to move upward by the second connecting plate. At this time, the air temporarily stored in the fixed cover can be squeezed. At the same time, the first one-way valve is opened and the second one-way valve is opened. The one-way valve is closed, and after the fifth elastic member is reset, the conical cover no longer moves. At this time, the top of the scraper just fits with the bottom of the conical cover, and at the same time, the bottom of the rectangular tube fits with the bottom of the conical cover. When the movable disk continues to move upward, it can drive the push pin to slide upward along the spiral groove, and can push the rotating rod and the scraper to rotate. At the same time, under the squeezing action of the gravity plate, the air temporarily stored in the fixed cover can enter the scraper through the second telescopic tube and be blown out through the filter, so that the blowing operation can be performed while the scraper is scraping, and the air can only be discharged through the discharge port. Under the guidance of the airflow, it is convenient to collect the impurities after rolling, so that the collection effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

The third moving rod 703 and the U-shaped frame 704 are driven to move by the second moving module 701, thereby driving the collecting box 705 to move, thereby moving the impurity collecting tank 707 to the bottom of the discharge valve 104, so as to facilitate the replacement of the positions of the extraction liquid collecting tank 706 and the impurity collecting tank 707.

[0130] See also Fig.10 , the second driving mechanism comprises:

[0131] The gear ring 2101 is fixedly sleeved on the side wall of the rotating column 10 .

[0132] The motor 2103 is fixed to the top of the concentration tank body 1 through the U-shaped seat 2102. The output end of the motor 2103 is fixedly connected with the gear 2104, and the gear 2104 is meshed with the ring gear 2101. When the motor 2103 is started, the rotation of the motor 2103 drives the rotation of the gear 2104, thereby driving the ring gear 2101 and the rotating column 10 to rotate.

[0133] Working principle: When concentrating, the extract is first fed into the concentration tank body 1 through the feed valve 101, and then the extract in the concentration tank body 1 is heated and concentrated, so that the organic solvent becomes steam and then passes through the first telescopic tube 19 and the solenoid valve 20 and then is discharged and collected through the steam valve 102. At the same time, the motor 2103 is started, and the rotation of the motor 2103 drives the rotation of the gear 2104, thereby driving the ring gear 2101 and the rotating column 10 to rotate, and then drives the rectangular tube 18 to rotate through the first connecting plate 17, so that the extract in the concentration tank body 1 can be stirred, which can improve the efficiency and quality of concentration. At the same time, when the rectangular tube 18 rotates, the bubbles on the liquid surface can pass through the gap between the two rectangular tubes 18, and under the action of the conical block 602, the bubbles can be broken, and the conical block 602 is provided with multiple groups, which can achieve a defoaming effect at different liquid level heights, thereby improving the efficiency and quality of concentration.

[0134] After the concentration is completed, the solenoid valve 20 is closed and the discharge valve 104 is opened. The concentrated silymarin extract with a high concentration can pass through the hollow plate 202 to the filter cloth 210 for filtration. The filtered silymarin extract is collected by the extract collection tank 706. At the same time, the cylinder 501 is started to move the connecting block 503 downward, and the moving plate 11 is driven to move downward through the second moving rod 502. When the moving plate 11 moves downward, the rotating rod 13 and the scraper 14 can be driven downward through the first reset mechanism, and the conical cover 12 can be driven downward synchronously through the second reset mechanism. When the movable disk 11 and the conical cover 12 are against the side wall of the conical block 602, the conical block 602 and the sliding rod 601 can be pushed to move into the rectangular tube 18. At the same time, the first elastic member 604 is compressed to ensure that the movable disk 11 and the conical cover 12 can normally pass over the conical block 602. At this time, the conical cover 12 can be used to scrape and clean the inner wall of the concentration tank body 1 and the residual silymarin on the surface of the rectangular tube 18 to avoid waste. At the same time, the cleaning is more convenient and quick. At the same time, the liquid can be squeezed to improve the efficiency and effect of filtration, thereby improving the efficiency and effect of concentration.

[0135] When the conical cover 12 is about to move to the bottom of the concentration tank body 1, the cylinder 501 is stopped. After the liquid in the concentration tank body 1 is completely discharged, the cylinder 501 is started again, so that the moving plate 11 and the conical cover 12 continue to move downward. When the scraper 14 contacts the conical surface 103, the bottom of the rectangular tube 18 is just flush with the bottom of the conical cover 12. When the moving plate 11 continues to move downward, the fourth elastic member 804 is gradually compressed. At the same time, the push pin 304 is driven to slide along the spiral groove 301 through the fixed plate 303, so that the rotating rod 13 and the scraper 14 can be driven to rotate, and the conical surface 103 can be moved downward. The remaining solid impurities are scraped and gathered at the center position of the bottom of the conical surface 103. After the rotation is completed, the scraper 14 can be aligned with the strip opening 15 again. When the movable disk 11 continues to move downward, the push pin 304 can move downward along the vertical groove 302. At this time, the fixed plate 303 is abutted against the top of the conical cover 12, thereby pushing the conical cover 12 to move downward. At the same time, the fifth elastic member 904 is compressed. At this time, the scraper 14 can move into the strip opening 15, so that the solid impurities can be squeezed through the conical cover 12, which can improve the collection effect of silymarin extract and avoid waste.

[0136] After the extrusion is completed, the third moving rod 703 and the U-shaped frame 704 are moved by the second moving module 701, and then the collecting box 705 is moved, so that the impurity collecting tank 707 is moved to the bottom of the discharge valve 104. Then, the first moving rod 206 is moved by the first moving module 205, and the baffle 209 is moved. At this time, the second moving plate 211 can be pushed to move, and the first moving plate 208 can be moved by the third elastic member 214. The second elastic member 213 is gradually compressed. At this time, the solid on the filter cloth 210 can be The solid impurities are pushed onto the baffle plate 209. When the baffle plate 209 moves to the bottom of the hollow plate 202, the second elastic member 213 is no longer compressed. When the baffle plate 209 continues to move, it can push the second movable plate 211 to move toward the first movable plate 208. At the same time, the third elastic member 214 is gradually compressed, so that the filter cloth 210 can be squeezed to squeeze out the residual silymarin extract therein to avoid waste. After the baffle plate 209 passes over the hollow plate 202, the solid impurities at the bottom of the concentration tank body 1 can pass through the hollow plate 202 and then be discharged through the discharge valve 104.

[0137] The movable disk 11 is driven upward to reset through the lifting mechanism, and the fourth elastic member 804 is gradually reset. At this time, the conical cover 12 can gradually move upward under the action of the fifth elastic member 904. At this time, the push pin 304 moves upward along the vertical groove 302. When the scraper 14 is exposed from the strip opening 15, the fixed plate 303 is separated from the top of the conical cover 12, and the fifth elastic member 904 is reset. When the movable disk 11 continues to move upward, it can push the pin 304 to move upward along the spiral groove 301, thereby pushing the rotating rod 13 and the scraper 14 to move forward. At this time, the conical cover 12 and the bottom of the conical surface 103 can be scraped and cleaned again, and guided to the top of the hollow plate 202 for discharge, so as to avoid the residue of solid impurities and ensure the collection effect.

[0138] When extruding, the conical cover 12 can move downward along the side wall of the scraper 14. At the same time, the fixed cover 404 is driven downward by the second connecting plate 403. At this time, the lower end of the conical rod 409 is against the top of the scraper 14, so that negative pressure is generated in the fixed cover 404. At the same time, the first one-way valve is closed and the second one-way valve is opened. At this time, external air can enter the fixed cover 404 through the air supply pipe 408 for temporary storage.

[0139] After the extrusion is completed, when the movable plate 11 moves upward, the conical cover 12 can gradually move upward along the side wall of the scraper 14, and at the same time, the fixed cover 404 is driven to move upward through the second connecting plate 403. At this time, the air temporarily stored in the fixed cover 404 can be squeezed. At the same time, the first one-way valve is opened and the second one-way valve is closed. After the fifth elastic member 904 is reset, the conical cover 12 no longer moves. At this time, the top of the scraper 14 just fits with the bottom of the conical cover 12. At the same time, the bottom of the rectangular tube 18 fits with the bottom of the conical cover 12. When the movable plate 1 When the screw 100 continues to move upward, it can drive the push pin 304 to slide upward along the spiral groove 301, and can push the rotating rod 13 and the scraper 14 to rotate. At the same time, under the squeezing action of the gravity plate 405, the air temporarily stored in the fixed cover 404 can enter the scraper 14 through the second telescopic tube 407 and be blown out through the filter 402, so that the scraper 14 can perform the blowing operation while scraping, and the air can only be discharged through the discharge port 201. Under the guidance of the airflow, it is convenient to collect the impurities after rolling, so that the collection effect is better.
