Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine extraction, in particular to a filter component, an extraction tank and application thereof in the preparation of traditional Chinese medicine oral liquid. Background Art

[0002] The extraction tank is a commonly used leaching and extraction equipment in pharmaceutical and chemical industries. It is particularly suitable for the leaching and extraction of components contained in plant products. The working principle of the extraction tank is a simple decoction process. The Chinese herbal medicine is soaked in water and heated by steam. After a certain period of time, the effective ingredients are extracted.

[0003] A traditional Chinese medicine extraction tank with application number 202011610004.3 includes a tank body, a slag discharge door, a lifting mechanism, a self-locking mechanism and a pressurized sealing mechanism. A feed port is provided on the top of the tank body, and a slag discharge port is provided on the bottom. The lifting mechanism is provided on the side of the tank body. The lifting mechanism is connected to the slag discharge door and is used to drive the slag discharge door to close and open the slag discharge port. The self-locking mechanism can lock and unlock the relative position of the slag discharge door and the tank body according to changes in the internal temperature of the tank body. The pressurized sealing mechanism can change the sealing between the slag discharge door and the slag discharge port by setting a pressurized sealing mechanism as the internal temperature of the tank body changes. However, during the use of the device, it is easy for medicinal liquid to remain in the medicinal residue, thereby causing waste of medicinal liquid.

[0004] A traditional Chinese medicine extraction tank with application number 201810378115.2 includes a container tank, a stirring mechanism and a uniform medicine distribution box are provided inside the container tank, a solvent injection mechanism is provided in the middle of the container tank, the stirring mechanism includes a feed pipe and a stirring blade fixed on the feed pipe, a motor mechanism for driving the feed pipe to rotate back and forth is provided on the top panel of the container tank, and a heating cavity 2 with a heating material inside is provided around the outer side of the feed pipe; the solvent auxiliary introduction mechanism includes an annular tube surrounding the container tank, but when the device is discharging the medicine liquid, the medicine residue is likely to cause blockage of the pipeline, thereby affecting the discharge of the medicine liquid.

[0005] At the same time, when the medicine liquid in the tank body is extracted, a filter is usually added in the drain pipe. In the process of extracting the medicine liquid in the tank body, the medicine residue is easy to block the filter in the drain pipe, making the extraction of the liquid in the drain pipe slow or even stop, and when the medicine residue is discharged from the lower end of the tank body, the residual medicine liquid in the medicine residue will also be discharged along with the medicine residue, thereby causing a waste of medicine liquid.

[0032] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0033] like Figures 1 to 4 As shown, the extraction tank of the present invention comprises a dosing and exhaust component 1, a tank body 2 and a material discharge component 3, a drainage component 4 is arranged on the tank body 2, the dosing and exhaust component 1 is arranged on the top of the tank body 2, and the material discharge component 3 is arranged at the lower part of the tank body 2, the dosing and exhaust component 1 is used for auxiliary addition of medicinal materials and water for preparing Chinese medicine oral liquid, and when steam heats the medicinal materials and water in the tank body 2 for decocting, the pressure in the tank body 2 will gradually rise, when the pressure in the tank body 2 exceeds the threshold value, the steam in the tank body 2 can be discharged through the dosing and exhaust component 1 to ensure the stable use of the tank body 2, after the preparation of the Chinese medicine oral liquid is completed, after the medicinal liquid in the tank body 2 is discharged to the medicine storage tank through the drainage component 4, the material discharge component 3 can discharge the medicinal residue in the tank body 2, so as to facilitate the next preparation of Chinese medicine oral liquid.

[0034] The material unloading assembly 3 includes a packaging bottom cover 301 rotatably arranged at the lower part of the can body 2, first hydraulic cylinders 302 are rotatably arranged on both sides of the can body 2, the output end of the first hydraulic cylinder 302 is rotatably connected to the packaging bottom cover 301, an auxiliary packaging sleeve 303 is rotatably arranged at the lower part of the can body 2, packaging rods 304 are evenly arranged on the outer side of the circumference of the packaging bottom cover 301, and a packaging groove 305 matching the packaging rod 304 is arranged on the lower side of the auxiliary packaging sleeve 303. After the first hydraulic cylinder 302 is started, the output end of the first hydraulic cylinder 302 is pushed out, and the output end of the first hydraulic cylinder 302 The packaging bottom cover 301 is deflected to open the bottom of the tank body 2, so that the medicine residue in the tank body 2 can be discharged downward under the action of gravity. After the medicine residue is discharged, the first hydraulic cylinder 302 begins to retract to deflect the packaging bottom cover 301. The deflection of the packaging bottom cover 301 closes the bottom of the tank body 2, and the packaging rod 304 on the packaging bottom cover 301 enters the packaging groove 305 on the auxiliary packaging sleeve 303, and then the auxiliary packaging sleeve 303 is rotated to lock the packaging bottom cover 301, so as to stably prepare the Chinese medicine oral liquid again.

[0035] The dosing exhaust assembly 1 includes a packaging top cover 101, which is arranged on the top of the tank body 2, an exhaust pipe 102 is arranged on the upper part of the packaging top cover 101, a dosing pipe 103 is arranged on the side end of the top of the packaging top cover 101, a sealing cover 104 is rotatably arranged at the mouth of the dosing pipe 103, a dosing hydraulic cylinder 105 is rotatably arranged on the top of the packaging top cover 101 at the side end of the dosing pipe 103, and the output end of the dosing hydraulic cylinder 105 is rotatably connected to the sealing cover 104. When it is necessary to add medicinal materials and water to the tank body 2, Start the dosing hydraulic cylinder 105 and retract it, so that the sealed cover 104 can be flipped to open the dosing tube 103, and then medicinal materials and water are added through the dosing tube 103. After the addition is completed, the output end of the dosing hydraulic cylinder 105 is extended to make the sealed cover 104 flipped to close the dosing tube 103. During the heating process of the medicinal materials and water in the tank body 2, when the pressure in the tank body 2 is too high, the tank body 2 can be depressurized in time through the exhaust pipe 102, thereby improving the stability of the equipment.

[0036] A second hydraulic cylinder 306 is rotatably provided on the can body 2 outside the auxiliary packaging sleeve 303, and the output end of the second hydraulic cylinder 306 is rotatably connected to the auxiliary packaging sleeve 303. A third hydraulic cylinder 307 is also rotatably provided on the can body 2 outside the auxiliary packaging sleeve 303, and the output end of the third hydraulic cylinder 307 is also rotatably connected to the auxiliary packaging sleeve 303. The output end of the second hydraulic cylinder 306 is extended, and the output end of the third hydraulic cylinder 307 is retracted, so that the auxiliary packaging sleeve 303 can rotate counterclockwise, so that the packaging rod 304 is stuck in the packaging groove 305 to complete the locking of the packaging bottom cover 301. When the output end of the second hydraulic cylinder 306 is retracted and the output end of the third hydraulic cylinder 307 is extended, the auxiliary packaging sleeve 303 can be rotated clockwise, so that the packaging rod 304 moves from the packaging groove 305 to a non-locking position, so that the locking of the packaging bottom cover 301 is released, and the packaging bottom cover 301 can be deflected with the assistance of the first hydraulic cylinder 302.

[0037] The drainage component 4 includes a drainage pipe 401, and there are multiple drainage pipes 401. An annular pipe 402 is arranged on the outside of the tank body 2. One end of the drainage pipe 401 is inserted into the tank body 2, and the other end of the drainage pipe 401 is connected to the annular pipe 402. A main pipe 403 is arranged on the outside of the annular pipe 402, and a drainage pump 404 is arranged on the main pipe 403. After the Chinese medicine oral liquid in the tank body 2 is decocted, the drainage pump 404 is started. With the assistance of the drainage pump 404, the Chinese medicine oral liquid in the tank body 2 enters the annular pipe 402 through the drainage pipe 401, and then the Chinese medicine oral liquid in the annular pipe 402 enters the liquid storage tank through the main pipe 403 for temporary storage, which improves the convenience of equipment use. A filter is usually added in the drainage pipe 401 to prevent the medicine residue in the tank body 2 from entering the drainage pipe 401.

[0038] In the process of preparing the oral Chinese medicine liquid, the present invention first starts the dosing hydraulic cylinder 105 to retract the output end of the dosing hydraulic cylinder 105. After the output end of the dosing hydraulic cylinder 105 retracts, the sealed cover 104 is deflected. After the sealed cover 104 is deflected, the opening of the dosing tube 103 is opened. At this time, the medicinal materials for decocting the oral Chinese medicine liquid can be added into the tank body 2, and then water is added into the tank body 2 through the dosing tube 103. After the medicinal materials and water are added, the dosing hydraulic cylinder 105 is started to extend the output end of the dosing hydraulic cylinder 105, so that the sealed cover 104 is flipped and covered on the dosing tube 103, so that the dosing tube 103 is closed, and then the medicinal materials in the tank body 2 are soaked in water for a fixed time.

[0039] After the soaking of medicinal materials is completed, high-temperature steam is introduced into the can body 2, and the can body 2 is heated with the assistance of the high-temperature steam, so that the can body 2 begins to decoct the medicine. During the decoction process, if the pressure in the can body 2 is too high, the pressure in the can body 2 can be relieved with the assistance of the exhaust pipe 102 to ensure the stable decoction in the can body 2.

[0040] After the decoction in the tank body 2 is completed, the drainage pump 404 is started. With the assistance of the drainage pump 404, the medicine liquid in the tank body 2 can enter the annular pipe 402 through the drainage pipe 401, and the medicine liquid in the annular pipe 402 will enter the main pipe 403, and then the medicine liquid in the main pipe 403 will enter the medicine storage tank for temporary storage.

[0041] After the liquid medicine in the can body 2 is extracted, the second hydraulic cylinder 306 and the third hydraulic cylinder 307 are started to extend the output end of the second hydraulic cylinder 306 and retract the output end of the third hydraulic cylinder 307, thereby causing the auxiliary packaging sleeve 303 to rotate clockwise, so that the packaging rod 304 is in locking contact with the packaging groove 305, and then the first hydraulic cylinder 302 is started to extend the output end of the first hydraulic cylinder 302, thereby causing the packaging bottom cover 301 to deflect and open the bottom of the can body 2. At this time, the medicine residue in the can body 2 can fall under the action of gravity, thereby completing the discharge of the medicine residue in the can body 2.

[0042] After the discharge of the medicinal residue in the tank body 2 is completed, the first hydraulic cylinder 302 is started to retract the output end of the first hydraulic cylinder 302, thereby deflecting the packaging bottom cover 301, so that the packaging rod 304 enters the packaging groove 305, and then the second hydraulic cylinder 306 and the third hydraulic cylinder 307 are started to retract the output end of the second hydraulic cylinder 306 and extend the output end of the third hydraulic cylinder 307, so that the auxiliary packaging sleeve 303 rotates counterclockwise, and the packaging rod 304 is locked with the packaging groove 305, so that the equipment can prepare the next Chinese medicine oral liquid.

[0043] The present invention also provides a filter assembly for an extraction tank. When extracting the liquid medicine in the tank body 2, a filter screen is usually added to the drain pipe 401. When the drain pipe 401 extracts the liquid medicine in the tank body 2, the drug residue is likely to block the filter screen in the drain pipe 401, causing the extraction of liquid in the drain pipe 401 to become slow or even stop. When the drug residue is discharged from the lower end of the tank body 2, the residual liquid medicine in the drug residue will also be discharged along with the drug residue, thereby causing a waste of the drug liquid. At the same time, when the drug residue is discharged from the lower end of the tank body 2, the drug residue is likely to block the tank body 2 to form a cavity, thereby affecting the discharge of the drug residue, and the discharge of the drug residue is not clean. For this reason, we have made the following improvements:

[0044] like Figures 1 to 7 As shown, the filter assembly includes a filter device 5, which is arranged on the side of the drain pipe 401 close to the tank body 2. When the drain pipe 401 extracts the medicinal liquid in the tank body 2, the medicinal residue is filtered with the assistance of the filter device 5 to prevent the medicinal residue from entering the drain pipe 401.

[0045] The filter device 5 includes a filter tube 501, a groove 502 is provided on the side of the drain pipe 401 close to the tank body 2, the filter tube 501 is arranged in the groove 502, a limiting groove 503 is provided on the drain pipe 401, a slider 504 is provided on one side of the limiting groove 503 of the filter tube 501, an annular limiting sleeve 505 is provided on the slider 504, the filter tube 501 is located in the tank body 2, a first filter hole 506 and a second filter hole 507 are provided on the top and bottom of the filter tube 501 respectively, a pressure sensor 508 is provided on the outer side of the filter tube 501 away from the drain pipe 401, and when the annular limiting sleeve 505 is pushed, the movement of the annular limiting sleeve 505 will The movement of the slider 504 will cause the filter tube 501 to move in the groove 502, and the movement of the filter tube 501 will cause the first filter hole 506 and the second filter hole 507 to move to the outside of the drain pipe 401, so that the medicine liquid in the tank body 2 can enter the drain pipe 401 through the first filter hole 506 and the second filter hole 507, and when the filter tube 501 moves in the groove 502, the drain pipe 401 will scrape off the medicine residue blocking the outside of the first filter hole 506 and the second filter hole 507, so as to ensure the smooth discharge of the medicine liquid, and the pressure sensor 508 is used to detect the pressure between the filter tube 501 and the medicine residue when it moves.

[0046] A mounting plate 509 is provided on the tank body 2 outside the discharge pipe 401, and a driving hydraulic cylinder 510 is provided on the side of the mounting plate 509 close to the discharge pipe 401. The output end of the driving hydraulic cylinder 510 is provided at the side end of the annular limit sleeve 505. When the driving hydraulic cylinder 510 is started, the output end of the driving hydraulic cylinder 510 can drive the annular limit sleeve 505 to move.

[0047] There are two driving hydraulic cylinders 510, which are respectively arranged on both sides of the discharge pipe 401. The slider 504 slides and limits in the limiting groove 503. The two driving hydraulic cylinders 510 provide power for the movement of the annular limiting sleeve 505, making the annular limiting sleeve 505 more stable when moving.

[0048] The first filter hole 506 is arranged on the side of the top of the filter tube 501 close to the pressure sensor 508, and the second filter hole 507 is arranged on the side of the bottom of the filter tube 501 away from the pressure sensor 508. There is a distance between the first filter hole 506 and the pressure sensor 508. When the filter tube 501 extends out of the groove 502, the first filter hole 506 works first, and the second filter hole 507 can work only after the filter tube 501 extends and moves a distance.

[0049] During the use of the present invention, when medicinal materials and water are added into the tank body 2, the device controls the driving hydraulic cylinder 510 to start, so that the driving hydraulic cylinder 510 is reciprocatedly extended and retracted, and the extension and retraction distance is less than the distance between the first filter hole 506 and the pressure sensor 508. The reciprocating extension and retraction of the driving hydraulic cylinder 510 is assisted by the annular limit sleeve 505 and the slider 504 to make the filter tube 501 reciprocate, and the reciprocating movement of the filter tube 501 makes the water in the tank body 2 vibrate to form a stirring effect on the water in the tank body 2, so that the mixing of water and medicinal materials is more sufficient, the soaking effect of medicinal materials is better, and the subsequent decoction effect is improved. Since there are multiple filter devices 5, the device controls the multiple filter devices 5 to operate in coordination, so that the filter tubes 501 in the multiple filter devices 5 are extended one by one, so that the extension of the filter tubes 501 in the multiple filter devices 5 is performed clockwise, ensuring that the stirring in the tank body 2 is sufficient, and the processing effect of the equipment is improved.

[0050] When the liquid medicine in the tank body 2 needs to be discharged after preparation, the equipment controls to start the drainage pump 404 and drive the hydraulic cylinder 510. With the assistance of the drainage pump 404, the drainage pipe 401 generates suction, and with the assistance of the driving hydraulic cylinder 510, the filter tube 501 is moved back and forth. At this time, the movement distance of the filter tube 501 will cause the first filter hole 506 to leak out while the second filter hole 507 does not leak out. Therefore, under the action of the suction force in the drainage pipe 401, the liquid medicine in the tank body 2 can pass through the first filter hole 506 and enter the drainage pipe 401, and then the liquid medicine in the drainage pipe 401 enters the liquid storage tank through the annular pipe 402 and the main pipe 403 for temporary storage.

[0051] During the use of the first filter hole 506, the first filter hole 506 is easily blocked by medicinal residues. Since the filter tube 501 moves back and forth, the drain pipe 401 will scrape off the medicinal residues on the outside of the first filter hole 506 through the reciprocating movement of the filter tube 501, thereby ensuring the smooth use of the first filter hole 506. At the same time, during the drainage of the first filter hole 506, the equipment will also control the operation rules of the multiple filter devices 5 to be consistent with the operation rules when the medicinal materials and water are added to the tank body 2, that is, the extension and retraction of the filter tubes 501 in the multiple filter devices 5 are performed clockwise.

[0052] As the medicine liquid in the tank body 2 is gradually discharged, the medicine residue gradually accumulates at the bottom of the tank body 2. At this time, when the filter tube 501 is moving back and forth, the detection value of the pressure sensor 508 will gradually increase. When the detection value of the pressure sensor 508 exceeds the threshold value, it indicates that the liquid level in the tank body 2 is lower than the first filter hole 506. The equipment controls the hydraulic cylinder 510 to increase its moving distance, thereby increasing the reciprocating moving distance of the filter tube 501, so that the second filter hole 507 can extend out of the drain pipe 401, so that the medicine liquid in the tank body 2 can enter the drain pipe 401 through the second filter hole 507. At the same time, the reciprocating movement of the filter tube 501 can also enable the drain pipe 401 to scrape off the medicine residue outside the second filter hole 507, ensuring that the medicine liquid can smoothly pass through the second filter hole 507 into the drain pipe 401.

[0053] When the detection value of the pressure sensor 508 increases and exceeds the threshold value, the equipment controls the multiple filter devices 5 to operate in coordination, so that one filter device 5 and the filter device 5 opposite to it operate synchronously, that is, the filter tubes 501 in the two filter devices 5 extend and retract synchronously, and the operation of the multiple filter devices 5 is still clockwise. When the filter tube 501 in one filter device 5 and the filter device 5 opposite to it extend synchronously, the two filter tubes 501 move toward each other to squeeze the medicinal material in the middle, so that the residual medicinal liquid in the medicinal material is squeezed out, and then the squeezed medicinal liquid can enter the drain pipe 401 through the second filter hole 507, thereby ensuring the sufficient discharge of the medicinal liquid and reducing the waste of the medicinal liquid in the medicinal material.

[0054] In the process of discharging the medicinal residue, the equipment controls multiple filter devices 5 to operate in coordination, so that the driving hydraulic cylinder 510 is extended and retracted reciprocatingly, so that the filter tubes 501 in the multiple filter devices 5 are extended to the limit distance. Through the reciprocating movement of the filter tubes 501, the medicinal residue stuck in the tank body 2 can be pushed and dropped, and when the filter tubes 501 are extended to the limit distance, the slider 504 will have a slight collision with the limit groove 503 to form vibration, which is also conducive to the discharge of the medicinal residue in the tank body 2 under the action of vibration, thereby improving the convenience of equipment use.

[0055] The main functions achieved by the present invention are: by setting a pressure sensor 508, the pressure between the filter tube 501 and the medicinal residue when it moves can be detected by the pressure sensor 508, so as to control the telescopic distance of the driving hydraulic cylinder 510 accordingly, and control the coordinated operation of multiple filter devices 5, so that the residual medicinal liquid in the medicinal material can be squeezed out, and at the same time, the reciprocating movement of the filter tube 501 can produce a stirring effect in the stage of adding medicinal materials and water, ensuring that the medicinal materials are fully soaked. When the medicinal liquid is discharged, the reciprocating movement of the filter tube 501 enables the drain pipe 401 to scrape off the medicinal residue blocked on the outside of the first filter hole 506 and the second filter hole 507. When the medicinal residue is discharged, the reciprocating movement of the filter tube 501 can assist the discharge of the medicinal residue in the tank body 2, and vibration is formed to assist the discharge of the medicinal residue, thereby improving the processing effect of the equipment.

[0056] The invention also provides an application of a filter assembly of an extraction tank in the preparation of a Chinese medicine oral liquid.

[0057] The installation, connection or setting methods of the extraction tank and the filter assembly of the present invention are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

Since the filter tube (501) is reciprocating, the drainage tube (401) will scrape off the medicinal residues outside the first filter hole (506) through the reciprocating movement of the filter tube (501), thereby ensuring smooth use of the first filter hole (506). At the same time, during the drainage of the first filter hole (506), the equipment will also control the operation rules of the multiple filter devices (5) to be consistent with the operation rules when the medicinal materials and water are added to the tank body (2), that is, the extension and retraction of the filter tubes (501) in the multiple filter devices (5) are performed in a clockwise direction. As the liquid medicine in the tank body (2) is gradually discharged, the medicine residue gradually accumulates at the bottom of the tank body (2). At this time, during the reciprocating movement of the filter tube (501), the detection value of the pressure sensor (508) gradually increases. When the detection value of the pressure sensor (508) exceeds the threshold value, it indicates that the liquid level in the tank body (2) is lower than the first filter hole (506). The device controls the hydraulic cylinder (510) to increase its movement distance, thereby increasing the reciprocating movement distance of the filter tube (501), so that the second filter hole (507) can extend out of the drainage pipe (401), so that the liquid medicine in the tank body (2) can enter the drainage pipe (401) through the second filter hole (507). At the same time, the reciprocating movement of the filter tube (501) can also cause the drainage pipe (401) to scrape off the medicine residue outside the second filter hole (507), thereby ensuring that the liquid medicine can smoothly pass through the second filter hole (507) and enter the drainage pipe (401). When the detection value of the pressure sensor (508) increases and exceeds the threshold value, the device controls the multiple filter devices (5) to operate in coordination, so that one filter device (5) and the filter device (5) opposite to it operate synchronously, that is, the filter tubes (501) in the two filter devices (5) extend and retract synchronously, and the operation of the multiple filter devices (5) is still performed in a clockwise direction. When the filter tubes (501) in one filter device (5) and the filter device (5) opposite to it extend synchronously, the two filter tubes (501) move towards each other to squeeze the medicinal material in the middle, so that the residual medicinal liquid in the medicinal material is squeezed out, and then the squeezed medicinal liquid enters the drainage pipe (401) through the second filter hole (507), thereby ensuring that the medicinal liquid is fully discharged and reducing the waste of the medicinal liquid in the medicinal material.
