[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Reference Figure 1-11The embodiment of the present invention provides a Yao medicine purification, concentration and extraction device, comprising a tank body 1 and an overflow plate 2 arranged in the tank body 1, on which the overflow plate 2 is sequentially provided with an accumulation groove 3 and a filtering and plugging mechanism along the flow direction of the liquid medicine, and the accumulation groove 3 is constructed at the bottom of the overflow plate 2; the filtering and plugging mechanism has a first state of filtering the liquid medicine on the overflow plate 2 and a second state of plugging the accumulation groove 3. The overflow plate 2 is provided with a plurality of accumulation grooves 3 and a plurality of filtering and plugging mechanisms.

[0036] Specifically, the overflow plate 2 is a plate-like structure horizontally arranged in the tank body 1, a receiving cavity is constructed on the top of the overflow plate 2, and an overflow groove 4 is constructed at one end of the overflow plate 2, and the height of the overflow groove 4 is lower than the height of the other side walls of the overflow plate 2, so that the liquid medicine will overflow through the overflow groove 4 when discharged into the receiving cavity, so that a liquid film can be formed in the tank body 1; the tank body 1 is hollow inside, and is provided with a liquid medicine inlet 5, a concentrated liquid outlet 6, a hot air inlet 7 and a hot air outlet 8; the liquid medicine inlet 5 is located at the top of the tank body 1, and is used to input liquid medicine into the overflow plate 2; the hot air inlet 7 is located at the bottom of the tank body 1, and is used to input hot air into the tank body 1, and the hot air is discharged from the bottom to the top of the tank body 1. The tank body 1 is provided with a plurality of air chambers, each of which is provided with a plurality of air chambers, and each of which is provided with a plurality of air chambers. The tank body 1 is provided with a plurality of air chambers, each of which ... The innovation of the embodiment of the present invention is that an accumulation groove 3 and a filter plugging mechanism are arranged on the overflow plate 2. The accumulation groove 3 is a groove body constructed at the bottom of the overflow plate 2. The filter plugging mechanism can be a filter structure slidably connected to the overflow plate 2 to filter and purify the medicine passing through the overflow plate 2 or to plug the accumulation groove 3. The accumulation groove 3 and the filter plugging mechanism are arranged adjacent to each other. When the medicine flows, it first passes through the accumulation groove 3 and then passes through the filter plugging mechanism. When the filter plugging mechanism is in the first state, it can filter the medicine passing through the overflow plate 2, and the filtered solid impurities can remain on one side of the accumulation groove 3 and settle in the accumulation groove 3. After the filter structure in the blocking mechanism is blocked or has been used for a period of time, the filter sealing mechanism switches to the second state to block the accumulation groove 3, and at the same time, the filter sealing mechanism no longer filters the medicine passing through the overflow plate 2, so as to ensure the normal flow of the medicine while minimizing the overflow of filtered solid impurities from the accumulation groove 3; multiple groups of accumulation grooves 3 and filter sealing mechanisms are arranged on the overflow plate 2, and after one group of filter sealing mechanisms is switched to the second state, the remaining filter sealing mechanisms in the first state can continue to filter the medicine, thereby ensuring the normal use of the filter structure while minimizing the blockage of the filter structure to hinder the flow of the medicine.

[0037] A Yao medicine purification, concentration and extraction device provided in an embodiment of the present invention can allow some solid impurities in the medicinal solution to settle into the accumulation groove 3 by setting up an accumulation groove 3; when the filtering and plugging mechanism is in the first state, it can filter the medicinal solution flowing through the overflow plate 2, and the filtered impurities are on one side of the accumulation groove 3. The filtering and plugging mechanism switches to the second state after being blocked or used for a period of time, so that the filtering and plugging mechanism can block the impurities on one side of the accumulation groove 3 into the accumulation groove 3, and try to avoid hindering the flow of the medicinal solution on the overflow plate 2, so that the remaining structures can continue to operate, and at the same time, the filtered solid impurities are restricted to try to avoid the filtered solid impurities from continuing to flow with the medicinal solution.

[0038] In yet another embodiment of the present invention, as an alternative to the above-mentioned filter structure slidably connected to the overflow plate 2, further, the filter blocking mechanism includes a filter plate 9 rotatably connected to the overflow plate 2. Specifically, the filter plate 9 is constructed as a filter screen structure as a whole, and the two ends of the filter plate 9 are respectively fitted with the two inner walls opposite to the overflow plate 2. A rotating shaft 10 is fixed at the bottom of the filter plate 9, and the rotating shaft 10 is rotatably connected to the overflow plate 2, and a dynamic sealing structure is provided at the rotating connection, and the bottom of the rotating shaft abuts against the inner wall of the stacking tank 3; a micro motor structure can be provided on the overflow plate 2 to drive the rotating shaft 10 and the filter plate 9 to rotate, which is a prior art and is not shown in the figure; the stacking tank 3, the rotating shaft 10 and the filter plate 9 are all arranged along the width direction of the overflow plate 2. When the filter plate 9 is perpendicular to the plane where the overflow plate 2 is located, the filter plate 9 isolates the accommodating cavity to filter the liquid medicine passing through the overflow plate 2, which is the first state of the filter plugging mechanism; when the filter plate 9 rotates to a position parallel to the plane where the overflow plate 2 is located, the filter plate 9 no longer filters the liquid medicine passing through the overflow plate 2 but blocks the stacking tank 3, which is the second state of the filter plugging mechanism. The advantage is that when the filter plate 9 is perpendicular to the overflow plate 2, the solid impurities on one side of the accumulation groove 3 tend to move toward the filter plate 9. During the process of the filter plate 9 rotating toward the side of the accumulation groove 3 (that is, during the process of the filter sealing mechanism switching from the first state to the second state), the solid impurities above the accumulation groove 3 can be pushed into the accumulation groove 3 through the filter plate 9 and sealed, so as to avoid the filtered solid impurities from flowing with the medicine again as much as possible.

[0039] Furthermore, in the flow direction of the liquid medicine, the plurality of filtering and plugging mechanisms are sequentially switched to the second state. Specifically, in the present embodiment, the plurality of filtering and plugging mechanisms can all be in the first state, that is, the plurality of filter plates 9 on the overflow plate 2 filter the liquid medicine at the same time. Obviously, the solid impurities filtered at the upstream filter plate 9 are more, so the state of the filtering and plugging mechanism can be sequentially switched from upstream to downstream during the use of the overflow plate 2, that is, in the flow direction of the liquid medicine, the filtering and plugging mechanism is sequentially switched from the first state to the second state.

[0040] As an alternative to all of the above-mentioned multiple filtering and plugging mechanisms being in the first state, preferably, two adjacent filtering and plugging mechanisms on the overflow plate 2 are maintained in the first state. Specifically, in the above-mentioned embodiment, multiple filter plates 9 filter the medicinal liquid on the overflow plate 2 at the same time. Obviously, this will hinder the flow of the medicinal liquid and even affect the overflow of the medicinal liquid. For this reason, only two adjacent filtering and plugging mechanisms among the multiple filtering and plugging mechanisms on the overflow plate 2 are in the first state. Preferably, in the flow direction of the medicinal liquid, the multiple filtering and plugging mechanisms switch states in sequence so that the multiple filter plates 9 are used in sequence, that is, the first and second filtering and plugging mechanisms upstream are preferentially placed in the first state to filter the medicinal liquid (such as Figure 2 As shown), correspondingly, the remaining filtering and plugging mechanisms are in the second state; as the device is used, the first upstream filtering and plugging mechanism will switch to the second state to seal the filtered impurities into the corresponding accumulation groove 3; when the first upstream filtering and plugging mechanism switches to the second state, the third upstream filtering and plugging mechanism is synchronously switched to the first state, so that the two filtering and plugging mechanisms on the overflow plate 2 are maintained in the first state; the advantage is that when an upstream filter plate 9 blocks the accumulation groove 3, the impurities filtered at the filter plate 9 may flow downstream with the medicinal solution. In this embodiment, maintaining two filter plates 9 on the overflow plate 2 can maintain a filtering and plugging mechanism to filter the medicinal solution when the state of an upstream filtering and plugging mechanism is switched, thereby minimizing the flow of impurities that have been filtered out with the medicinal solution again and thus improving the purity of the medicinal solution.

[0041] In another embodiment provided by the present invention, as an alternative solution for the above-mentioned motor structure to drive the filter plate 9 to rotate, further, the filter blocking mechanism includes a limiting block 11 fixed on the overflow plate 2, a torsion spring (torsion spring not shown) is arranged between the overflow plate 2 and the filter plate 9, and a connecting rod 12 is fixed on the filter plate 9. Specifically, the limiting block 11 is fixed on the outer wall of the overflow plate 2, one end of the rotating shaft 10 extends to the outside of the overflow plate 2 and is fixed to the connecting rod 12 at the end, that is, the connecting rod 12 is fixed to the filter plate 9 through the rotating shaft 10; the torsion spring is used to force the filter plate 9 to move away from the corresponding stacking groove 3 until the connecting rod 12 rotates with the rotating shaft 10 to the position of contacting the limiting block 11, the filter plate 9 is perpendicular to the overflow plate 2, and the corresponding filtering and blocking mechanism is in the first state; in the present embodiment, the filter plate 9 is perpendicular to the overflow plate 2 under normal conditions, so that an extrusion structure (such as a combination of a cylinder and an extrusion block) can be set in the tank body 1 to squeeze the connecting rod 12, thereby forcing the connecting rod 12 to move away from the limiting block 11, and then forcing the filter plate 9 to rotate to block the stacking groove 3.

[0042] Furthermore, a wedge block 13 is slidably connected to the overflow plate 2, and an elastic member 14 is provided between the overflow plate 2 and the wedge block 13. Specifically, a slide groove 15 is constructed on the outer wall of the overflow plate 2, and the wedge block 13 is slidably connected in the slide groove 15 to approach or move away from the rotating shaft 10; the elastic member 14 can be an elastic sheet or spring structure in the prior art, one end of the elastic member 14 is fixed to the outer wall of the overflow plate 2, and the other end is fixed to the wedge block 13, so that the wedge block 13 is forced to approach the rotating shaft 10 along the slide groove 15 through the elastic member 14; when the filter plate 9 rotates toward the side of the stacking tank 3, the connecting rod 12 rotates synchronously with the filter plate 9 around the rotating shaft 10, and the connecting rod 12 will rotate during the rotation process. The wedge surface of the wedge block 13 is abutted to force the wedge block 13 to squeeze the elastic member 14 and move away from the rotating shaft 10 along the chute 15 until the filter plate 9 rotates to the position of blocking the stacking slot 3. The connecting rod 12 is on the side of the wedge block 13 away from the limiting block 11, so that the wedge block 13 is reset to the end of the chute 15 close to the rotating shaft 10 under the action of the elastic member 14 to limit the position of the connecting rod 12 (at this time, the connecting rod 12 is abutted against the wedge block 13 under the action of the torsion spring), and the filter plate 9 is prevented from being reset under the action of the torsion spring as much as possible. The advantage of such a setting is that when the filter plate 9 is forced to rotate to block the stacking slot 3 by the extrusion structure, the position of the connecting rod 12 can be passively limited by the wedge block 13, thereby limiting the position of the filter plate 9, and preventing the filter plate 9 from opening the stacking slot 3 under the action of the torsion spring to cause the impurities in the stacking slot 3 to overflow.

[0043] As an alternative to the above-mentioned cylinder and extrusion block, further, a driving plate 16 is slidably connected in the tank body 1, and a plurality of first contact blocks 17 are constructed on the driving plate 16, and a protrusion 18 is constructed on the connecting rod 12. A plurality of first unlocking blocks 19 are constructed on the driving plate 16. Specifically, a linear driving mechanism is provided in the tank body 1 to drive the driving plate 16 to slide vertically in the tank body 1. The linear driving mechanism can adopt a screw structure or a cylinder structure in the prior art. This is the prior art and will not be described in detail. A plurality of first contact blocks 17 are constructed on the side of the driving plate 16 close to the overflow plate 2, and the protrusion 18 is located on the side of the connecting rod 12 away from the overflow plate 2. A plurality of first contact blocks 17 correspond to a plurality of protrusions 18, so that when the driving plate 16 moves downward in the tank body 1, the first contact blocks 17 can contact the corresponding protrusions 18, and the first contact blocks 17 do not interfere with the connecting rod 12 during the process (such as Figure 6The figure shows a schematic diagram of the structure after the first abutment block 17 forces the filter plate 9 to block the accumulation groove 3, wherein the wedge block 13 locks the connecting rod 12, and at this time the wedge block 13 is located above the first unlocking block 19, and the protrusion 18 is located below the first abutment block 17 and the protrusion 18 is not on the movement stroke of the first abutment block 17); when the filter plate 9 is perpendicular to the overflow plate 2, the connecting rod 12 abuts against the limiting block 11, and when the driving plate 16 moves downward, the first abutment block 17 abuts against the end of the protrusion 18 away from the rotating shaft 10 to force the protrusion 18 and the rotating shaft 10 to rotate, thereby forcing the filter plate 9 to overcome the elastic force of the torsion spring to block the accumulation groove 3, until the filter plate 9 blocks the accumulation groove 3, the protrusion 1 8 is separated from the first interference block 17; that is, when the filter plate 9 is perpendicular to the overflow plate 2, the end of the protrusion 18 away from the rotating shaft 10 is located on the movement stroke of the first interference block 17, and when the filter plate 9 blocks the accumulation groove 3, the end of the protrusion 18 away from the rotating shaft 10 is not on the movement stroke of the first interference block 17; in the process of the first interference block 17 forcing the protrusion 18 to rotate, the connecting rod 12 passively squeezes the wedge block 13 to force the wedge block 13 to avoid along the slide groove 15, until the protrusion 18 is separated from the first interference block 17, and the connecting rod 12 moves to the side of the wedge block 13 away from the limiting block 11, so that the wedge block 13 is reset under the action of the elastic member 14 and limits the connecting rod 12. A plurality of first unlocking blocks 19 are constructed on one side of the first driving plate 16 close to the overflow plate 2, and the thickness of the wedge block 13 is greater than the thickness of the connecting rod 12 (the thickness of the wedge block 13 is substantially equal to the sum of the thicknesses of the connecting rod 12 and the protrusion 18), that is, the wedge block 13 has a portion protruding from the connecting rod 12, and the plurality of first unlocking blocks 19 correspond to the portions of the plurality of wedge blocks 13 protruding from the connecting rod 12; such arrangement enables the wedge-shaped surface of the corresponding wedge block 13 protruding from the connecting rod 12 to be squeezed by the first unlocking block 19 when the driving plate 16 moves downward, so as to force the wedge block 13 to avoid along the slide groove 15 again, until the first unlocking block 19 is separated from the wedge block 13, and the wedge block 13 releases the restriction on the connecting rod 12, so that the connecting rod 12 can be rotated to a position against the limiting block 11 under the action of the torsion spring, thereby making the filter plate 9 perpendicular to the overflow plate 2. The advantage of such a configuration is that, through the multiple first interference blocks 17, the multiple filter plates 9 can be forced to rotate to block the corresponding accumulation grooves 3, and after the filter plates 9 rotate, the connecting rods 12 are restricted by the corresponding wedge blocks 13, so that the filter plates 9 keep blocking the accumulation grooves 3 (this is the second state of the filter blocking mechanism); through the multiple first unlocking blocks 19, the multiple wedge blocks 13 can be forced to release the restrictions on the corresponding connecting rods 12, so that the filter plates 9 can be reset to the position of the interference restriction blocks 11 under the action of the torsion springs, so that the filter plates 9 are perpendicular to the overflow plates 2 (this is the first state of the filter blocking mechanism).

[0044] In order to keep the two adjacent filter plugging mechanisms on the overflow plate 2 in the first state, preferably, in the flow direction of the liquid medicine, the heights of the plurality of first resistance blocks 17 and the plurality of first unlocking blocks 19 gradually increase. Specifically, in this embodiment, the plurality of filter plugging mechanisms on the overflow plate 2 are all in the second state, and the positions of the plurality of first resistance blocks 17 and the plurality of first unlocking blocks 19 are equidistantly arranged, so that during the downward movement of the driving plate 16, the first upstream first unlocking block 19 ( Figure 8 The first one on the left in the middle releases the restriction on the first upstream connecting rod 12, so that the first upstream filter plate 9 is perpendicular to the overflow plate 2, and then the first upstream filtering and blocking mechanism is switched to the first state; then the driving plate 16 continues to move downward to pass through the second upstream ( Figure 8 The first unlocking block 19 switches the second upstream filtering and plugging mechanism to the first state. At this time, the two filtering and plugging mechanisms on the overflow plate 2 are kept in the first state (i.e. Figure 8 The corresponding overflow plate 2 is in state); then the driving plate 16 continues to move downward (such as Figure 8 In the process, the driving plate 16 drives the first resistance block 17 and the first unlocking block 19 to continue to move downward), so as to switch the third upstream filtering and blocking mechanism to the first state through the third upstream first unlocking block 19, and at the same time, the first upstream first resistance block 17 resists the first upstream protrusion 18 to force the first upstream filter plate 9 to block the accumulation groove 3, and the first upstream filter plate 9 is restricted by the corresponding wedge block 13 after blocking the accumulation groove 3, that is, in this process, when the first upstream filtering and blocking mechanism is switched to the second state, the third upstream filtering and blocking mechanism is synchronously switched to the second state, so as to keep two filter plates 9 on the overflow plate 2 to filter and purify the liquid medicine; then the driving plate 16 continues to move downward to switch the second upstream filtering and blocking mechanism to the second state through the second upstream first resistance block 17, and at the same time, the fourth upstream filtering and blocking mechanism is switched to the first state through the fourth upstream first unlocking block 19; and so on, until all the filtering and blocking mechanisms on the overflow plate 2 are switched to the second state, the impurities in the multiple accumulation grooves 3 in the overflow plate 2 can be cleaned.

[0045] In another embodiment provided by the present invention, further, a plurality of overflow plates 2 are arranged in the tank body 1. Specifically, Fig. 9 As shown, multiple groups of overflow plates 2 are staggered and fixed on the inner wall of the tank body 1 ( Fig. 9Only two groups of overflow plates 2 are shown in the figure, and the overflow groove 4 is located at the end of the overflow plate 2 away from the tank body 1, so that the flow path of the liquid medicine is square wave-shaped when the liquid medicine overflows on the multiple overflow plates 2. Correspondingly, the rising path of the hot air in the tank body 1 is also square wave-shaped due to the influence of the multiple overflow plates 2, so that the contact area between the hot air and the liquid film can be increased, thereby improving the evaporation efficiency of the liquid medicine; because the multiple overflow plates 2 are staggered, the flow directions of the liquid medicine on the upper and lower overflow plates 2 are opposite, and accordingly, the filter plate 9, the connecting rod 12 and the wedge block 13 and other structures are all arranged in the opposite direction. (The filter plates 9, connecting rods 12 and wedge blocks 13 of the multiple groups of overflow plates 2 are all on the same side of the overflow plate 2), and for this purpose, a second resistance block 20 and a second unlocking block 21 are arranged on the driving plate 16. In the flow direction of the liquid medicine, the heights of the multiple second resistance blocks 20 and the multiple second unlocking blocks 21 gradually increase; the second resistance block 20 has the same structure as the first resistance block 17, and the second unlocking block 21 has the same structure as the first unlocking block 19, that is, in this embodiment, the first resistance block 17 and the first unlocking block 19 correspond to the overflow plate 2 on the left side of the tank body 1 (that is, with Fig.11 The second contact block 20 and the second unlocking block 21 correspond to the overflow plate 2 on the right side of the tank body 1 (i.e., the overflow plate 2 on the upper side of the tank body 1). Fig.11 The overflow plate 2 on the lower middle side corresponds to the overflow plate 2 on the right side), so as to sequentially switch the states of multiple filtering and blocking mechanisms on the overflow plate 2 on the right side (the movement process of the second contact block 20 and the second unlocking block 21 is the same as the movement process of the first contact block 17 and the first unlocking block 19, which will not be repeated here); since the flow directions of the liquid on the overflow plate 2 corresponding to the first contact block 17 (or the first unlocking block 19) and the overflow plate 2 corresponding to the second contact block 20 (or the second unlocking block 21) are different, Fig.10 The overall arrangement trend of the plurality of first resistance blocks 17 and the plurality of second resistance blocks 20 (the plurality of first unlocking blocks 19 and the plurality of second unlocking blocks 21) is different. Preferably, the second downstream filtering and blocking mechanism ( Fig.11 When the filtering and plugging mechanism in the overflow plate 2 on the upper middle side is the first one downstream, and the unillustrated part on the left is the second filtering and plugging mechanism downstream) is switched to the second state, the filtering and plugging mechanism on the lower overflow plate 2 on the first upstream side (that is, Fig.11The filtering and plugging mechanism in the middle and lower overflow plate 2 is switched to the first state; correspondingly, when the first filtering and plugging mechanism in the downstream of the upper overflow plate 2 is switched to the second state, the second filtering and plugging mechanism in the upstream of the lower overflow plate 2 is switched to the first state; the advantage of such a configuration is that, in the overall flow direction of the medicinal liquid in the tank body 1, the flow directions of the medicinal liquid on the multiple overflow plates 2 are different. Obviously, it is a waste of resources to keep two filter plates 9 on multiple overflow plates 2 at the same time, and the simultaneous use of multiple filter plates 9 will also hinder the flow of the medicinal liquid. For this reason, only two filtering and plugging mechanisms are kept in the first state on the multiple overflow plates 2, and the multiple filtering and plugging mechanisms of the multiple overflow plates 2 are switched in sequence in the flow direction of the medicinal liquid to filter and purify the medicinal liquid in the tank body 1.

[0046] In this embodiment, the cross-section of the accumulation groove 3 is triangular, so that the bottom wall of the overflow plate 2 is affected by the multiple accumulation grooves 3 to form multiple tooth structures. In this way, the flow of hot air can be disturbed by the multiple tooth structures, so that the hot air forms a vortex between two adjacent tooth structures, thereby increasing the contact time between the hot air and the liquid film, and ensuring as much as possible that a saturated water vapor airflow is formed when the hot air moves to the top of the tank body 1.

[0047] In this embodiment, the filter plate 9 is not provided at the first upstream accumulation groove 3 in each overflow plate 2, so that the accumulation groove 3 can receive the medicine liquid and alleviate the impact force of the medicine liquid, and try to avoid the impact of the filter plate 9 structure and the filtered impurities when the medicine liquid flows into the overflow groove 4.

[0048] In this embodiment, the first resistance block 17 and the second resistance block 20 are staggered, and the first unlocking block 19 and the second unlocking block 21 are staggered to avoid interference between the various structures when the driving plate 16 moves down along the tank body 1; the overflow plate 2 and the inner wall of the tank body 1 can be detachably connected by bolts or snaps and other structures. When the driving plate 16 moves down to the bottom of its stroke, multiple filtering and plugging mechanisms are switched to the second state. At this time, the multiple overflow plates 2 can be removed from the tank body 1 for cleaning. At the same time, the driving plate 16 is reset to the top of the tank body 1 to facilitate the switching of the states of multiple filtering and plugging mechanisms in sequence next time.

[0049] Optionally, when the drive plate 16 moves to the bottom of its stroke, the tank body 1 stops concentrating and extracting the medicinal liquid until all the medicinal liquid in the tank body 1 is discharged, and then the drive plate 16 is driven to move up and reset through the linear drive mechanism. During the process, multiple first unlocking blocks 19 and second unlocking blocks 21 sequentially resist the bottom of the wedge blocks 13 on the multiple overflow plates 2, so as to force the multiple wedge blocks 13 to avoid along the slide groove 15 and release the restrictions on the multiple connecting rods 12, thereby rotating the multiple filter plates 9 to a position perpendicular to the overflow plate 2, so that the impurities in the accumulation tank 3 can be cleaned in the tank body 1, which is convenient for the next concentration and extraction of the medicinal liquid.

[0050] A method for purifying, concentrating and extracting Yao medicine, comprising any of the Yao medicine purification, concentrating and extracting devices described above, to filter the medicinal solution through a first state of a filtering and blocking mechanism, the filtering and blocking mechanism being switched to a second state after being blocked or used for a period of time, so that the filtering and blocking mechanism can block impurities on one side of a stacking tank 3 into the stacking tank 3.

[0051] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
