Detailed Description

As shown in figures 1-5, a medicine leaching tank comprises an outer tank body 1 and an inner mesh barrel 2. The outer tank 1 is a solid rectangular parallelepiped casing. One side of the outer tank body 1 is provided with a first end cover 3, one end of the first end cover 3 is hinged with an ear plate on the outer tank body 1, and the other end is fixed with a U-shaped plate 14. A screw and nut component 10 is hinged to the outer tank body 1 below the U-shaped plate 14, and a screw in the screw and nut component 10 penetrates through a gap 11 corresponding to the U-shaped plate 14 and then is tightly pushed by friction of a nut in the screw and nut component 10. When the nut needs to be taken down, the nut is slightly unscrewed and then is screwed out. In addition, because outer jar of body 1 is used for storing medicine and the mixed liquid of extracting the solvent, consequently still is equipped with draw-in groove 12 on first end cover 3, passes through draw-in groove 12 joint between first end cover 3 and the outer jar of body 1, and is equipped with sealed pad 13 in the draw-in groove 11. And liquid leakage is avoided by sealing and locking. Through setting up this structure, can conveniently open and seal and close outer jar of body 1 fast.

The periphery of the inner wall of the outer tank body 1 is provided with a connecting plate 15, and the inner net cylinder 2 is connected with the outer tank body 1 through a bolt through the connecting plate 15. The inner mesh 2 is here in a lying position inside the outer tank 1. The inner mesh cylinder 2 is provided with the leakage holes, and when in leaching, certain plant raw materials are added into the inner mesh cylinder 2 for leaching, so that a leaching solution and the plant raw materials are separately placed, an extracting solution is separated from the extracted plant raw materials, and a filtering step for the extracting solution and the extracted plant raw materials after extraction is omitted. An inner net barrel 2 is hinged with a second end cover 4, the orientation of the second end cover 4 is the same as that of the first end cover 3, and plant raw materials can be conveniently put in or taken out. The second end cap 4 is also secured in the same manner as the first end cap 3, all by a hinged screw and nut assembly 10. Except that the screw-nut assemblies 10 are circumferentially arranged and correspond to four corners of the outer can body 1. These four orientations are relatively large in space, and facilitate operation of the screw-nut assembly 10 by appropriate selection of the positions.

In order to achieve uniform heating of the medicine, a rotating shaft 16 is centrally installed in the inner net cylinder 2 at the end far away from the second end cover 4, and the rotating shaft 16 is connected with the cantilever 6 through a flange. The cantilever 6 is L-shaped, and the longer part is deviated from the axle center of the rotating shaft 16. A plurality of groups of stirring rings 7 are arranged on the longer section of the cantilever 6. Each group of stirring rings 7 comprises a first spiral ring 7-1 and a second spiral ring 7-2, and the spiral directions of the first spiral ring 7-1 and the second spiral ring 7-2 are opposite and the spiral pitches are the same. The cross sections of the first spiral ring 7-1, the second spiral ring 7-2 and the cantilever 6 are both tubular, so that the overall weight can be reduced. Since the stirring ring 7 is a spiral stirring ring, it has continuity during stirring.

Because the cantilever 6 is eccentrically arranged, the cantilever 6 can always keep a vertical downward state under the action of gravity. When the leaching tank takes place to rotate, cantilever 6 takes place to rotate for the leaching tank, realizes inside stirring, is favorable to like this that the medicine raw materials can thermally equivalent for the medicine leaching effect is better more abundant.

The outer tank body 1 and the inner mesh cylinder 2 are both made of tetrafluoro materials. The material can bear the temperature of medicine extraction, has corrosion resistance, and avoids the corrosion of some medicinal materials.

The upper side of the outer tank body 1 is provided with a lifting lug plate 8, and the lower side is provided with a connecting lug plate 9. The lifting lugs 8 can be used for lifting purposes, while the coupling lugs 9 are used for coupling with the endless chain drive 17.

The endless chain drive 17 here comprises a carrier 18, to which the four rotary shafts are rotatably connected by bearings 18. The four rotating shafts are respectively a first rotating shaft 19, a second rotating shaft 20, a third rotating shaft 21 and a fourth rotating shaft 22, the first rotating shaft 19, the second rotating shaft 20, the third rotating shaft 21 and the fourth rotating shaft 22 are arranged side by side in pairs, paired chain wheels 23 are arranged on each rotating shaft at intervals, and a chain 24 sequentially bypasses the chain wheels 23 on the four rotating shafts and is rectangular as a whole. The chain 24 is provided with a fixing lug plate 25 on the chain link, and the fixing lug plate 25 is connected and fixed with the connecting lug plate 9 through a bolt. In addition, one end of the first rotating shaft 19 extends out of the groove body 26 and is driven by a belt transmission mechanism 27 and a motor 28. When the first rotating shaft 19 is driven to rotate, the two chains rotate in the same speed and direction, and further the outer tank body 1 is driven to rotate in the circumferential direction.

The endless chain drive 17 is arranged in a tank 26, and hot water or steam is introduced into the tank 26 for heating, so that the leaching temperature is ensured. When the leaching tank moves circularly in the tank body 26 along with the circular chain transmission mechanism 17, the leaching tank turns over along with the circular motion, on the one hand, the stirring ring 7 in the leaching tank can stir when the tank body is reversed, and the plant medicines in the leaching tank can be heated uniformly by combining the two parts, so that the whole leaching tank is more sufficient.

The working principle and the process are as follows: the medicine raw materials and the extraction solvent are placed in the inner net barrel 2, and the corresponding first end cover 3 and the second end cover 4 are covered. Then the outer tank body 1 is horizontally placed and is reliably connected with the annular chain transmission mechanism 17 one by one. Drive a plurality of outer tanks 1 through annular chain drive 17 and carry out the annular motion on the vertical, because cantilever 6 eccentric settings, consequently can take place the upset when the leaching jar is in the corner, and because cantilever 6 need remain vertical downwards all the time under the action of gravity, consequently relative rotation can take place for interior net section of thick bamboo 2 for cantilever 6 to realize inside stirring. Under the action of overturning and stirring the leaching tank, the medicine raw materials in the leaching tank can be uniformly heated, so that the leaching is more sufficient.

After the completion of leaching, because the plant material of leaching jar is located an inner net section of thick bamboo 2, and the leaching liquor is located the interval between outer jar of body 1 and an inner net section of thick bamboo 2, can keep apart leaching liquor and plant material like this, conveniently carry out direct coarse filtration. The outer tank body 1 is provided with a liquid outlet 29 with a piston, and after the operation is finished, the liquid outlet 29 can be opened to discharge and collect the coarse-filtered leaching liquor. The first and second end caps 3, 4 are then opened and the waste material is removed.
