The three-way valve is controlled manually or automatically by a controller.

The structure forms of the filtering barrels are the same, and different filtering functions are corresponding to different stations. Fig. 7 shows the internal structure of one of the filter drums, which can be seen to include a drum wall 29 and a drum base 30, as shown in fig. 9 and 10, with a series of stationary leak holes 31 at the peripheral edge of the drum base 30, and a central rotating shaft 43 at the center of the drum base 30. And a rotary disc 44 sleeved at the bottom of the filter vat body, wherein a series of moving through holes 47 are distributed on the edge of the rotary disc 44, and a shaft hole is arranged in the center of the rotary disc 44, as can be seen in fig. 9 and 10. The central rotating shaft is fitted in the shaft hole and provided with an anti-falling structure (for example, a protruding annular stop is provided at the end of the central rotating shaft), so that the tub base 30 and the turntable 44 are mounted together to form a composite chassis. As can be seen in fig. 8, there are respective side gears 45 at the peripheral edge of the turntable, and a series of safety pins 46 at the peripheral edge between the tub base and the turntable to ensure that the two do not become disengaged during relative rotation.

Based on the assembly relationship between the barrel base and the rotary table shown in fig. 7, 9 and 10, when the rotary table rotates a small angle relative to the barrel base, the fixed leak hole and the movable through hole can be in correspondence or dislocation, the upper and lower holes are in a conduction state when in correspondence, and the upper and lower holes are in a stop state when in dislocation.

As shown in fig. 6, arc-shaped shifting teeth 28 are distributed and fixed on the inner part of the outer bracket closed barrel 1 as required, so that when the whole rotating disk 10 rotates and the corresponding filter barrel is close to the arc-shaped shifting teeth 28, the corresponding filter barrel can be shifted by the arc-shaped shifting fork 28 to rotate by a proper angle, and the size of the rotating angle is determined by the arc length university of the arc-shaped shifting teeth 28. The arc length of dialling the tooth through the arc that designs suitable makes the carousel can be dialled the tooth by the arc and rotate a suitable angle when rotating, and then is the on-state when making the corresponding hole position of bucket base and carousel correspond, is the off-state when both positions misplace. Therefore, the turning degree of the rotary disc is controlled, and the on-off state of the corresponding filter barrel can be controlled.

Fig. 7 also shows that a filter screen 32 is located in the middle of the interior of the cylinder wall 29, a support grate 33 is located below the filter screen 32, a bottom grate 34 is located below the support grate 33, spring seats 35 are respectively located at the circumferential edges of the support grate 33, and return springs 36 are respectively accommodated in the spring seats 35. Under the action of the reset springs 36, the support grate 33 is in the upper position, and the filter screen is kept in the upper position.

The filter screen, support grate, backing grate and return spring are assembled as shown in fig. 15 and 16. In fig. 16 it can be seen that the support grate 33 comprises a series of cross bars and hollow areas 40 in the middle, and the filter screen is laid flat on the upper side of the support grate.

As can also be seen in fig. 16, there are stepped grooves 41 on the support grates, the outer diameter of the upper part of each stepped groove 41 is larger than that of the bottom through hole, and retaining pins 42 are sleeved in the stepped grooves 41. Each anti-drop nail 42 comprises a nail body and a top nail head, and the diameter of the top nail head is larger than that of the nail body. Wherein the nail head is positioned in the step groove 41, the nail body penetrates through the bottom of the step groove and is perforated, and the lower end of the nail body is fixed on the bottom lining grate 34. So that when the return spring pushes the support grate 33 up to its raised position, the grate 34 can naturally sag in the configuration shown in fig. 13 and 17. It can be seen that when the grate 34 is in the sagging position, the raised height of the grate does not completely cover the side holes 37 of the support grate side walls, thereby forming combined weep holes 39 to facilitate the downward discharge of the liquid medicine from the weep holes 39.

The grate 34 shown in fig. 15 includes a base and an upper series of projections arranged in a matrix, with longitudinal and transverse relief grooves 38 between adjacent projections. Wherein, each protrusion can be matched and sleeved in the corresponding support grate hollow-out area 40, and each abdicating groove 38 can be sleeved on the ribs of the support grate.

As shown in fig. 14, when the flushing platen 79 is pressed down continuously, the support grate 33 is compressed and the return spring is forced to move downward until it is near the bottom of the filter vat, the grate 34 is supported by the base 30 of the filter vat and cannot move, but the continued compression causes the support grate 33 to continue to move downward, thereby allowing the grate 34 to enter the inside of the support grate 33, i.e., the raised top surface of the grate enters the top of the hollowed-out area of the support grate, as shown in fig. 14. The weep holes 39 are now closed and the support grate remains flush with the upper surface of the bottom grate.

Fig. 6 shows a relationship between the on-off state of each filter vat at different stations, and when the filter vat is at the P1 position, i.e. the initial position when the filter vat is at the filtration stage, the filter vat is in the on-state, i.e. the upper and lower holes of the combined tray (vat base and rotary tray) at the bottom of the filter vat are corresponding, and when the mixture of the liquid medicine and the dregs of a decoction is introduced into the filter vat, the dregs of a decoction are blocked by the filter screen, and the liquid medicine is discharged into the concentrated liquid medicine tank 91 below.

In the figure, the position P2 is an ultrasonic level filter barrel, and the ultrasonic generator 78 is used for carrying out ultrasonic vibration on the residual medicine dregs in the barrel so as to promote effective tiny particles in the medicine dregs to be separated from the fibrous tissues of the medicine dregs through the ultrasonic vibration. In the process of the working procedure, the on-off state of the bottom of the filter barrel is not controlled.

In the figure, the washing-stage filter vat at position P3 is located in front of the station, and an arc-shaped shifting tooth 281 is fixed on the inner wall of the outer support closed barrel 1 at a corresponding height, so that the filter vat can be shifted to rotate by a proper angle when entering the station, that is, the vat base and the rotary table are in a cut-off state after rotating.

At this station, the water pipe 87 pumps and discharges the liquid in the reserve tank 90 into the filter vat corresponding to the station, so as to facilitate the flushing operation.

As shown in FIG. 13, an electric push rod 98 is installed below the movable support 16, and a flushing platen 79 is fixed at the telescopic end below the electric push rod 98. By controlling the electric push rod to do telescopic motion, the flushing pressure plate 79 is repeatedly pressed (a series of water-permeable holes are distributed on the plate surface of the flushing pressure plate 79), so that the liquid medicine moves downwards from the upper part of the filter screen through the liquid leakage holes and moves from the lower part of the filter screen through the liquid leakage holes. The stored water in the inner end of the standby water tank 90 is not concentrated liquid medicine, and the stored water is introduced into the filter vat at the station and continuously passes through the filter screen up and down, so that a plurality of dregs are repeatedly washed, and medicinal components generated by ultrasonic vibration in the previous working procedure are washed out. In the process of entering the next procedure, the bottom of the filter vat is in a conducting state by the drive of the arc-shaped shifting teeth 282, and the flushing water is discharged into the spare water tank 90 again. It should be noted that, the washing platen 79 of this station need not to press the filter screen, the support grate and the bottom lining grate into the bottom of the filter vat, and only needs to make the three reciprocate in the standby water.

The specific structure of the extrusion-stage filter barrel corresponding to P4 in fig. 6 is shown in fig. 14, in the filter barrel corresponding to the station, the flushing platen 79 is required to move further downwards until the dregs of a decoction are stressed, the non-concentrated liquid medicine can be deeply inserted into the deep fiber layer and extruded out through repeated stamping, and the effective medicinal substances in the deep layer of the dregs of a decoction can be repeatedly extracted for multiple times. Before the working procedure is put into place, the channel at the bottom of the filter barrel needs to be cut off through the arc-shaped poking teeth 283, and after the working procedure (the filter barrel) is put into place, the spare water on the upper layer of the spare water tank is sucked and drained into the filter barrel corresponding to the working position through the water pump 92 for extrusion and filtration.

In this position, as the flush platen 79 continues to be depressed until it is near the bottom of the filter vat, the grate 34 is held immobile by the filter vat base 30 so that the grate 34 enters the interior of the support grate 33 and the support grate is flush with the grate upper surface. Thereby providing a pressing support surface and ensuring that the filter screen cannot deform in the pressing process. Under the action of the return spring, the pressurizing process is changed from weak to strong and from strong to weak, and the pressurizing process is repeated for a plurality of times in sequence. The medicinal residue fiber tissue can be destroyed by squeezing to release deep medicinal microparticles. The process is transferred to the next process, the bottom of the filter barrel is driven to be in a conducting state through the arc-shaped poking teeth 284, and the filtrate is discharged into the standby water barrel.

The wringing stage filter vat in position P5 of fig. 6 is the same as in position P4, except that the medicated water ram is in position P4, and the medicated water ram is not in position P5. In the process, after the liquid medicine is extruded out, the residual medicine dregs enter the next working procedure.

In fig. 6, P6 is a suction filter vat. One way of achieving the function is shown in fig. 17, it can be seen that the function device above the filter vat is a suction mechanism, the mechanism comprises a suction pipe 50 which is hung on the movable support 16, the bottom of the suction pipe 50 is connected with a suction tube 51 with a diameter being enlarged, the bottom of the suction tube 51 is connected with a middle rotary tube 52 through a thrust bearing 53, the bottom of the middle rotary tube 52 is fixed with a flat suction cover 58, the lower port of the flat suction cover 58 is a strip-shaped rectangular suction port, and one side of the edge of the suction port is fixed with a rubber sealing strip 59, so that the other side of the suction port is supported to form a feeding gap.

A motor base 54 is fixed to the outside of the suction cylinder 51, a suction driving motor 55 is fixed to the motor base 54, a driving gear 56 is mounted on a rotating shaft thereof, and a driven gear 57 is mounted on the middle drum 52, and the driving gear is engaged with the driven gear. Thereby this motor rotation can drive the flat cover 58 of suction rotates, when cleaning the dregs of a decoction that is located the filter mantle top, can continuously suck the dregs of a decoction, and discharge to the dregs of a decoction pond in. Wherein, the outer end of the suction pipe 50 is communicated with the closed herb residue pool through a herb residue suction pipeline, and the other end of the herb residue pool is connected with a negative pressure mechanism through a suction pipeline.

Based on above six processes, can carry out abundant processing to medicinal material dregs of a decoction part in proper order, make the medical composition (particle and solution) after handling discharge into reserve tank, after carrying out above-mentioned circulation many times, when the liquid medicine concentration reaches and is close to with concentrated liquid medicine to the concentration in the reserve tank, utilize water pump 92 with the whole suctions of liquid medicine in the reserve tank, discharge into concentrated liquid medicine incasement through concentrated liquid medicine pipe 93 to increase concentrated liquid medicine output.

Example 2: in addition to embodiment 1, another pumping mechanism is shown in fig. 19, which includes a pumping tube 50 fixed to a movable support 16, an elbow 60 connected to a lower portion of the pumping tube 50, a side riser 61 connected to a lower portion of the elbow 60, and a side rotating tube 62 mounted to a lower portion of the side riser 61 through a bearing 63 in fig. 1.

A transverse rail 64 is fixed at the bottom of the side rotating pipe 62, a sliding block 65 is sleeved on the transverse rail 64, a rail wheel 66 is installed between the sliding block and the transverse rail, an inner cavity is arranged at one side of the sliding block, a suction opening is arranged at the bottom of the inner cavity, and a rubber strip is fixed at one side of the edge of the suction opening, so that the other side of the suction opening is supported to form a feeding gap.

A suction hood 71 is connected in a sealing manner to the top of the slide interior and is connected via a suction line 72 to the side line 62.

A driven gear 75 is attached to the side vertical pipe 61, a rail rotating motor 73 is fixed to an end of the horizontal rail 61, and a driving gear 74 is attached to a rotating shaft of the motor and meshed with the driven gear 75.

Meanwhile, a vertical rod 69 is fixed on the upper part of the sliding block, a rope pulley 68 is fixedly sleeved on the side vertical shaft, a pull rope 70 is wound on the rope pulley, and the outer end of the pull rope is fixed on the top of the vertical rod 69.

So that when the motor is rotated, it will rotate the transverse shaft 64. Meanwhile, the pull rope is driven to wind the rope pulley along a single direction, and the length of the outer end of the pull rope is continuously shortened in the process of winding the pull rope to the rope pulley, so that the slider is pulled to be close to one side of the side rotating pipe 62. Also mounted on the cross rail 64 is a thrust spring 67 which is capable of driving the slider towards the distal end of the cross rail. Thus, when the motor rotates in the reverse direction, the pulley releases the pull rope and the slider is moved toward the distal end of the lateral slider by the urging force of the urging spring 67.

Based on the structure and the motion relation, it can be seen that the motor can drive the transverse rail to rotate when rotating, and the transverse rail can drive the sliding block and the suction inner cavity thereof to rotate when rotating. While rotating, the slider is pulled to move closer to or away from the proximal end of the transverse rail. Therefore, when the motor is shaped or reversely rotated, the sliding block and the suction cavity thereof can be driven to rotate spirally, and the functions of cleaning and sucking the medicine dregs on the surface of the filter screen in a spiral track are realized.

Meanwhile, a torsion spring is sleeved between the fixed cylinder 80 and the upper side surface of the inner slide block, namely, one end of the torsion spring is fixedly inserted into the inner wall of the fixed cylinder 80, and the other end of the torsion spring is fixedly inserted into the upper wall of the inner slide block 84.

Meanwhile, a butt-joint inclined surface 86 is respectively arranged at the lower port of the fixed cylinder 80 and the upper port of the rotary cylinder 81. Naturally, the washing platen 79 moves the inner slider 84 downward via the rotation shaft 82, so that the fixed cylinder is separated from the rotary cylinder. However, when the electric push rod 98 moves downward and the washing platen is brought to the bottom, the electric push rod continues to move downward to engage the abutting inclined surfaces 86 of the fixed cylinder and the rotary cylinder, i.e., the pressure of the electric push rod 98 is transmitted to the upper side of the washing platen 79. Under the action of the butting inclined plane 86, when the electric push rod 98 moves downwards, at the moment when the fixed cylinder is in contact with the rotary cylinder, the fixed cylinder pushes the rotary cylinder to move downwards and is accompanied with a rotation function, so that the grinding function is realized while extrusion is realized. The torsion spring can keep the rotary cylinder to naturally reset after being separated from the inclined plane butt joint, so that the rotary cylinder can rotate again next time when being in butt joint with the fixed cylinder.
