Description

Technical Field

[0001] The utility model relates to the field of drug processing, in particular to an extraction tower for drug extraction. Background Art

[0002] During the processing of dried lacquer resin, crab shell, barberry, Tibetan celery, licorice, rabbit grass, cypress fruit, arisaema, sea buckthorn, Sichuan Senecio, Artemisia selengensis, barberry, slag, various biles, etc., the active ingredients need to be extracted through the extraction tower first, and then processed into plaster-type medicines through other processes.

[0003] After searching, the Chinese patent publication number CN221131068U discloses an extraction tower for drug extraction. The patent uses a horizontal bar, a spring column, a mounting plate, a vertical bar and a cleaning brush to effectively scrape off the drugs on the side wall of the tower body, while the cleaning brush buffers the force on the side wall of the tower body to protect the inner wall of the tower body; through a second motor, a screw rod, a slider, a scraper, a discharge chute, an electric push rod and a block, impurities on the surface of the filter plate can be scraped off and collected in a centralized manner, which brings convenience to the workers' operation.

[0004] However, when the cleaning brush is used to scrape the medicine on the side wall of the tower body, part of the medicine may be mixed in the cleaning brush, affecting the cleaning effect. Utility Model Content

[0005] The purpose of the present invention is to provide an extraction tower for drug extraction in order to solve the above problems.

[0026] A stirring mechanism is provided in the extraction tower 3, and the stirring mechanism includes a rotating motor 401 bolted to the top of the extraction tower 3. The output end of the rotating motor 401 is connected to the rotating shaft 402 through a coupling. The outer wall of the rotating shaft 402 is fixedly connected to multiple groups of circumferentially arranged stirring rods 403. The end of the stirring rod 403 is fixedly connected to a brush plate 404, and the brush plate 404 is fixedly connected to a number of bristles that are tightly attached to the inner wall of the extraction tower 3.

[0027] A filtering mechanism is provided below the extraction tower 3, which includes a filter box 501 bolted to the top of the base 1, and the filter box 501 is located below the discharge funnel 303. A collecting box 503 is slidably connected between the inner walls of the filter box 501, and a plurality of filter holes are provided on the bottom wall of the collecting box 503. The solid medicine is filtered and collected through the collecting box 503, and one end of the collecting box 503 extends out of the filter box 501 and is welded with a handle. A support bar 502 is fixedly connected between the inner walls of the filter box 501, and the collecting box 503 is located at the top of the support bar 502, and the collecting box 503 is supported by the support bar 502. A pump 504 is bolted to one side of the filter box 501, and the water outlet of the pump 504 is connected to a liquid outlet pipe 505, and the water inlet of the pump 504 is connected to a liquid inlet pipe. The liquid inlet pipe extends into the filter box 501, and the pump 504 is started to pump the liquid in the filter box 501 away through the liquid outlet pipe 505.

[0028] The top of the brush plate 404 is fixedly connected with a connecting ring 601, and the top of the connecting ring 601 is fixedly connected with a number of circumferentially arranged protrusions 602. The inner top wall of the extraction tower 3 is slidably connected with a number of circumferentially arranged slide rods 603. The bottom of the slide rod 603 extends into the extraction tower 3 and is fixedly connected with a knocking block 604 abutting against the connecting ring 601. The top of the slide rod 603 extends out of the extraction tower 3 and is fixedly connected with a limited block 605. A spring 606 is connected between the knocking block 604 and the inner top wall of the extraction tower 3. The spring 606 is wrapped around the outer circumference of the slide rod 603, and the corners at the top of the protrusion 602 and the corners at the bottom of the knocking block 604 are rounded to facilitate the relative movement of the protrusion 602 and the knocking block 604. The inner wall of the extraction tower 3 is fixedly connected with a number of circumferentially arranged convex strips 607. During the rotation of the brush plate 404, the bristles on the brush plate 404 are restricted by the convex strips 607 and will be deformed. When the brush plate 404 is separated from the convex strips 607, the bristles rebound and reset, making it easier to flick off the medicine between the bristles.

[0029] Working principle: add the medicine into the extraction tower 3 through the feeding pipe 301, screw the sealing plug 302 to seal the feeding pipe 301, start the rotating motor 401, the rotating motor 401 drives the rotating shaft 402 to drive the stirring rod 403 to rotate, and mix the medicine in the extraction tower 3. The rotation of the stirring rod 403 will drive the brush plate 404 to rotate, and the medicine on the inner wall of the extraction tower 3 will be scraped off by the brush plate 404. When the brush plate 404 rotates, it drives the connecting ring 601 and the protrusion 602 to rotate. When the protrusion 602 abuts against the knocking block 604, the protrusion 602 drives the knocking block 604 to move upward. When the protrusion 602 rotates away, the knocking block 604 moves downward rapidly under the action of the elastic force of the spring 606, The connecting ring 601 is knocked to shake off the medicine between the bristles. During the rotation of the brush plate 404, the bristles on the brush plate 404 are restricted by the ridges 607 and will be deformed. When the brush plate 404 is separated from the ridges 607, the bristles rebound and reset, which makes it easy to flick off the medicine between the bristles. After a certain period of time, the medicine in the extraction tower 3 is poured into the filter box 501, and the solid medicine is filtered in the collection box 503. The pump 504 is started to draw the filtered liquid in the filter box 501 away through the liquid outlet pipe 505. After the medicine in the extraction tower 3 is completely poured out, the rotating motor 401 is kept started for a period of time, and the inner wall of the extraction tower 3 is cleaned again by the brush plate 404, and then the rotating motor 401 is turned off.
