DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] like Figures 1 to 3As shown, the present invention provides a device for soaking and extracting effective components of Chinese medicinal materials, comprising:

[0032] An extraction barrel 1, on the side wall of the extraction barrel 1 are arranged an exhaust pipe 2, a water inlet pipe 3 and a material port 4 in sequence from top to bottom, a closed door is installed at the material port 4, and a filter screen 5 is installed on the inner wall of the extraction barrel 1;

[0033] A hammer crushing mechanism, which is disposed at the top of the extraction barrel 1 and is used to hammer the Chinese medicinal materials on the filter screen 5;

[0034] A lifting piston, which is disposed below the filter screen 5 and is slidably mounted in the extraction barrel 1. The lifting piston is used to adjust the liquid level in the extraction barrel 1;

[0035] A heating component 6, which is mounted on the side wall of the extraction barrel 1 and is used to heat the liquid in the extraction barrel 1;

[0036] A filter assembly is installed on the side wall of the extraction barrel 1 below the filter screen 5, the liquid outlet of the filter assembly is located below the lifting piston, and the liquid inlet of the filter assembly is located below the filter screen 5 and is arranged corresponding to the lifting piston;

[0037] The liquid collecting tank 7 is fixedly installed at the bottom end of the extraction barrel 1. The bottom end of the extraction barrel 1 is provided with a liquid outlet 8. The extraction barrel 1 is connected with the liquid collecting tank 7 through the liquid outlet 8. A liquid outlet pipe 9 is installed at the bottom of the liquid collecting tank 7.

[0038] Valves are installed on the exhaust pipe 2, the water inlet pipe 3 and the liquid outlet pipe 9;

[0039] Also includes:

[0040] The controller, the hammer crushing mechanism, the lifting piston, the heating component 6 and the valve are all electrically connected to the controller.

[0041] When the present invention is in use, Chinese medicinal materials are placed into the extraction barrel 1 through the material inlet 4 and mounted on the filter screen 5. After the Chinese medicinal materials are placed, the closed door is closed, and the controller controls the lifting piston to move up so that the lifting piston contacts the filter screen 5. A proper amount of extracting liquid is added into the extraction barrel 1 through the water inlet pipe 3. Then the controller controls the heating component 6 to heat the extracting liquid in the extraction barrel 1 to a specified temperature. At the same time, the hammer mechanism is controlled to hammer the Chinese medicinal materials on the filter screen 5. During this process, the lifting piston supports the filter screen 5 to prevent the filter screen 5 from being damaged, so as to realize the immersion extraction of the Chinese medicinal materials on the filter screen 5. After the specified extraction time is reached, the controller controls the lifting piston to move down. When the liquid inlet end of the filter component is exposed, the extracting liquid above the lifting piston is filtered by the filter component and flows into the bottom of the extraction barrel 1, and enters the collecting tank 7 through the liquid outlet 8, and is finally collected through the liquid outlet pipe 9.

[0042] In addition, during the extraction process, the pressure in the extraction barrel 1 is monitored by a pressure sensor arranged in the extraction barrel 1. When the pressure value reaches the set upper pressure limit, the controller controls the valve on the exhaust pipe 2 to open and discharge part of the steam, thereby keeping the pressure value in the extraction barrel 1 always within the set range.

[0043] After the extraction of the Chinese medicinal materials is completed and the extract is collected, the closed door is opened to take out the medicinal residues and the next extraction work can be carried out.

[0044] A further optimization scheme is to hammer the Chinese medicinal materials separately and ensure the stirring effect of the Chinese medicinal materials during the hammering process. The hammer crushing mechanism includes a telescopic cylinder 10 fixedly installed on the top of the extraction barrel 1, and the movable end of the telescopic cylinder 10 is fixedly connected with a hammer head 11. The hammer head 11 is gap-matched with the inner wall of the extraction barrel 1, and the telescopic cylinder 10 is electrically connected to the controller.

[0045] By utilizing the gap between the hammer head 11 and the inner wall of the extraction barrel 1, when the hammer head 11 rises, the extract above the hammer head 11 can pass through the gap to impact the Chinese medicinal materials on the filter screen 5, and the impact effect is utilized to achieve a stirring effect on the Chinese medicinal materials.

[0046] A further optimization scheme is to adjust the position of the lifting piston to facilitate the control of the extraction and separation of Chinese medicinal materials. The lifting piston includes a telescopic cylinder 12 fixedly installed at the bottom end of the extraction barrel 1, and the movable end of the telescopic cylinder 12 is fixedly connected to a piston head 13, and the piston head 13 slides with the inner wall of the extraction barrel 1; the telescopic cylinder 12 is electrically connected to the controller.

[0047] During use, by adjusting the position of the piston head 13, when the piston head 13 blocks the liquid inlet end of the filter component, the sealing effect of the piston head 13 can ensure the normal immersion and extraction operation of the Chinese medicinal materials. When the piston head 13 moves down to expose the liquid inlet end of the filter component, the extract above the piston head 13 will flow into the filter component under the action of gravity, and the filter component is used to filter the extract to separate the tiny Chinese medicinal material residues in the extract.

[0048] To further optimize the solution, in order to facilitate the adjustment of the position of the filter 5, so as to facilitate the cleaning of the Chinese medicinal material residues on the filter 5 out of the extraction barrel 1 after the extraction operation is completed, a slide groove 14 is opened on the inner wall of the extraction barrel 1 in the vertical direction, and the filter 5 is slidably installed in the slide groove 14, and the slide groove 14 is located above the liquid inlet end of the filter assembly.

[0049] When in use, the filter screen 5 can be pushed upward by the lifting piston, thereby changing the position of the filter screen 5, and the filter screen 5 can be limited by the setting of the slide groove 14, thereby limiting the sliding range of the filter screen 5 to avoid affecting the drug residue separation operation.

[0050] A further optimized solution is provided, in order to improve the stirring effect on the extraction liquid, an installation cavity is opened inside the piston head 13, in which a motor 15 is fixedly installed, and the motor 15 is electrically connected to the controller; a rotating shaft 16 is fixedly connected to the output shaft of the motor 15, and a plurality of stirring rods 17 are fixedly connected to the top end of the rotating shaft 16, the stirring rods 17 are located below the filter 5, and the stirring rods 17 are arranged at equal intervals along the circumference of the rotating shaft 16; a sleeve 18 is sleeved on the outer side of the rotating shaft 16, the bottom end of the sleeve 18 is in contact with the piston head 13, and the top end of the sleeve 18 is in contact with the stirring rod 17.

[0051] When in use, the motor 15 can drive the rotating shaft 16 and the stirring rod 17 to rotate, thereby improving the stirring effect of the extract and improving the extraction efficiency; and by arranging the stirring rod 17 at the top of the rotating shaft 16, the stirring rod 17 can be used to support the filter 5 under the action of the jacking piston, thereby improving the stirring effect of the extract while maintaining the supporting and protective effect on the filter 5 to prevent the filter 5 from being damaged during the hammering process; and by arranging the sleeve 18 under the stirring rod 17, the sleeve 18 can be used to protect the motor 15 from being damaged by the hammering.

[0052] According to a further optimization scheme, a countersunk hole is provided in the middle of the top of the filter screen 5 , a screw 19 is provided in the countersunk hole, and the filter screen 5 is installed on the top of the rotating shaft 16 through the screw 19 .

[0053] The filter 5 is connected to the rotating shaft 16 as a whole by the screw 19, and the filter 5 can be flushed by the extraction liquid by controlling the lifting piston to rise and fall in a small range, which can not only ensure that the filter 5 will not be blocked, but also further improve the stirring effect of the Chinese medicinal materials and the extraction efficiency through the movement of the filter 5. The setting of the countersunk hole can make the top of the screw 19 keep flush with the top of the filter 5, and use the protruding structure at the top of the screw 19 to achieve the limit between the filter 5 and the rotating shaft 16, without affecting the rotation of the stirring rod 17.

[0054] To further optimize the solution, in order to facilitate the replacement and cleaning of the filter barrel 20 and ensure the filtering and separation effect, the filtering assembly includes a filter barrel 20 arranged on the outside of the extraction barrel 1, and the upper and lower ends of the filter barrel 20 are fixedly connected with a connecting pipe 21, and the ends of the connecting pipe 21 are connected to the extraction barrel 1.

[0055] At the same time, in order to ensure the efficiency of filtration, a pump can be installed on the connecting pipe 21 at the liquid inlet end of the filter barrel 20.

[0056] According to a further optimized solution, in order to facilitate the extraction liquid to be discharged from the extraction barrel 1 , an arc-shaped collecting groove 22 is provided on the inner bottom surface of the extraction barrel 1 , and the liquid outlet 8 is arranged at the bottom of the arc-shaped collecting groove 22 .

[0057] According to a further optimized solution, the cross section of the liquid collecting tank 7 is a trapezoidal structure, a countersunk groove 23 is provided at the bottom of the liquid collecting tank 7, and the liquid outlet pipe 9 is installed in the countersunk groove 23.

[0058] The Chinese medicinal material effective component soaking and extraction device provided by the present invention does not require excessive human intervention when soaking and extracting the Chinese medicinal materials. The hammering process of the hammer crushing mechanism can not only realize the hammering treatment of the Chinese medicinal materials, but also can realize a certain stirring of the Chinese medicinal materials during the reciprocating descending and ascending process of the hammer crushing mechanism, thereby helping to improve the efficiency of the extraction operation. Moreover, the control parameters in the process can be preset through the controller. Therefore, the Chinese medicinal material effective component soaking and extraction device provided by the present invention has the advantages of simple operation, less human intervention, and a high degree of automation.

[0059] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
