DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] A multifunctional extraction tank, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it comprises a tank body 1, on which a plurality of supporting legs 6 are fixedly installed, a feeding pipe 2 and a liquid inlet pipe 15 are connected and installed on the top of the tank body 1, a slag discharge port 3 is provided at the bottom of the tank body 1, and a sealing cover 4 is provided in cooperation, a liquid discharge pipe 13 is connected and installed on one side of the tank body 1, a jacket 10 is provided on the external fixed sleeve of the tank body 1, the jacket 10 is fixedly connected with the outer wall of the tank body 1 facing the side wall of the tank body 1, a steam pipe 11 and a drain pipe 12 are connected and installed on the jacket 10 in sequence, a vertical pipe 5 is fixedly installed in the tank body 1, the vertical pipe 5 is fixedly connected to the inner wall of the tank body 1 through a plurality of connecting rods, the vertical pipe 5 is coaxially arranged with the tank body 1, and the vertical pipe 5 has a plurality of connecting rods in the vertical pipe 5. A coaxial rotating shaft 7 is provided, the rotating shaft 7 is rotatably mounted on the tank body 1, a coaxial spiral blade 8 is fixedly mounted on the rotating shaft 7, the outer periphery of the spiral blade 8 is in sliding contact with the inner wall of the vertical tube 5, one end of the rotating shaft 7 is fixedly connected to the output shaft of the first motor 9, the output shaft of the first motor 9 is coaxially arranged with the rotating shaft 7, the first motor 9 is fixedly mounted on the tank body 1, the output shaft of the first motor 9 extends into the reserved hole at the top of the tank body 1, and is fixedly connected with the rotating shaft 7, the rotating shaft 7 is rotatably mounted in the reserved hole through a bearing, and an annular mesh plate and a lifting device for driving the mesh plate to rise and fall are provided in the tank body 1. The present invention has a simple structure and an ingenious design. It can not only squeeze the medicinal materials to be extracted, but also realize the circulation of the medicinal materials through the vertical tube 5 and the spiral blade 8. The position of the medicinal materials is constantly changed, so that the medicinal materials at different positions can be fully filtered and extracted in turn, which solves the problem that the filtering extraction effect of the medicinal materials that have been accumulated in the middle position is poor. The extrusion effect of the medicinal materials is better and more uniform, which can improve the extraction efficiency, meet the actual needs, and is suitable for promotion. When using the present invention, the medicinal materials to be extracted are put into the tank body 1 from the feeding pipe 2, water is passed into the tank body 1 from the liquid inlet pipe 15, and then steam is passed into the cavity between the jacket 10 and the tank body 1 from the steam pipe 11 to heat the tank body 1. The generated condensed water is discharged from the drain pipe 12. During heating, the medicinal materials are squeezed through the mesh plate to immerse the medicinal materials below the liquid surface to improve the extraction efficiency. At the same time, the first motor 9 drives the rotating shaft 7 and the spiral blade 8 to rotate together, and the medicinal materials at the bottom of the tank body 1 are transported to the top of the tank body 1, and then fall into the water again and are squeezed through the mesh plate again. In this reciprocating cycle, the extracted liquid is discharged through the drain pipe 13, and the generated medicinal material residue is discharged through the residue discharge port 3.

[0017] Specifically, if Figure 1As shown, the mesh plate described in this embodiment includes two outer rings 20, which are distributed up and down, and inner rings 21 are respectively arranged inside the outer rings 20. The outer rings 20 and the inner rings 21 are sleeved outside the spiral blades 8 and are coaxially arranged. One end of a plurality of tapered rods 22 are rotatably connected to the outer rings 20, and the other end of the tapered rods 22 is rotatably connected to the inner ring 21. The tapered rods 22 are evenly distributed in the outer ring 20. The thick end of the tapered rods 22 is rotatably connected to the inner circumference of the outer ring 20 through a bearing, and the thin end of the tapered rods 22 is rotatably connected to the inner wall of the reserved hole on the inner ring 21 through a sealed bearing. The tapered rods 22 in the two outer rings 20 are staggered, and the gap formed by the tapered rods 22 on the two outer rings 20 is a filtering groove 28. The interior of the inner ring 21 is hollow, and the tapered rods 22 extend into the inner ring 21 and are fixedly installed coaxially. A first bevel gear 23 and several second motors 24 are fixedly installed in the inner ring 21. The wires of the second motors 24 pass through the inner wall of the inner ring 21, and the wires are sealed against the inner wall of the inner ring 21. Coaxial second bevel gears 25 are fixedly installed on the output shafts of the second motors 24. The second bevel gears 25 mesh with the corresponding first bevel gears 23. The first bevel gears 23 of the same inner ring 21 are meshed with the same bevel gear ring 26. The bevel gear ring 26 is rotatably installed in the inner ring 21. The bevel gear ring 26 is coaxially arranged with the inner ring 21. The inner circumference of the bevel gear ring 26 is rotatably connected to the inner wall of the inner ring 21 through a bearing. The two outer rings 20 are connected through several hydraulic push rods 27. One end of the hydraulic push rod 27 is fixedly connected to the outer ring 20 on the upper side, and the other end of the hydraulic push rod 27 is fixedly connected to the outer ring 20 on the lower side. After the medicinal materials transported by the spiral blades 8 fall from the top of the vertical tube 5, they will fall onto the conical rod 22 on the upper outer ring 20, and the second motor 24 will drive the second bevel gear 25 to rotate, and the first bevel gear 23 will drive the corresponding conical rod 22 to rotate, and then the bevel gear ring 26 will drive all the conical rods 22 in the same inner ring 21 to rotate together, and the conical rods 22 on the upper and lower outer rings 20 will rotate together. When the medicinal materials pass through the filtering grooves 28 formed by the gaps between the conical rods 22, the materials larger than the gaps will be filtered, and the medicinal materials will be squeezed or pulled when passing through the filtering grooves 28, further crushing the medicinal materials and increasing the extraction efficiency; setting up multiple second motors 24 can increase the driving force; by controlling the simultaneous extension or shortening of several hydraulic push rods 27, the spacing between the conical rods 22 on the upper and lower outer rings 20 can be adjusted, thereby adjusting the filtering accuracy.

[0018] Specifically, Figure 1As shown, the lifting device described in this embodiment includes several electric push rods 30, and the upper outer ring 20 is installed in the tank body 1 through the electric push rods 30. The fixed end of the electric push rod 30 is fixedly connected to the inner wall of the tank body 1 through the connecting rod, and the movable end of the electric push rod 30 is fixedly connected to the upper outer ring 20. Through the extension and retraction of the electric push rod 30, the two outer rings 20 are driven to move upward or downward, that is, the mesh plate is driven to move. When moving downward, the medicinal materials in the tank body 1 are squeezed so that the medicinal materials are immersed in the liquid, thereby improving the extraction efficiency.

[0019] Further, such as Figure 1 , Figure 2 , Figure 3 As shown, a plurality of blades 40 are fixedly mounted on the conical rod 22 of the present embodiment, and the blades 40 on the conical rod 22 are evenly distributed around the circumference. When the conical rod 22 rotates, the blades 40 thereon are driven to rotate together, cutting large pieces of medicinal materials into small pieces, so that the medicinal materials can be quickly fused and reacted with the liquid, thereby increasing the extraction efficiency.

[0020] Furthermore, Figure 1 As shown, the bottom of the tank body 1 in this embodiment is in an inverted cone shape. The inverted cone shape of the bottom of the tank body 1 facilitates the sliding of the medicinal materials to the lower end of the vertical pipe 5 so as to be transported to the top to form a circulation, and it is easier to discharge the extracted medicinal material residue from the residue discharge port 3.

[0021] Furthermore, Figure 1 As shown, in the present embodiment, a sealing gasket 60 is provided inside the sealing cover 4. The sealing gasket 60 can increase the sealing performance and prevent liquid leakage.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
