Description

Technical Field

[0001] The utility model belongs to the technical field of traditional Chinese medicine processing, and particularly relates to a traditional Chinese medicine hot reflux extraction and concentrator. Background Art

[0002] In the traditional Chinese medicine (TCM) pharmaceutical industry, extraction is a key step in TCM production, and its effectiveness directly impacts the quality and efficacy of the final product. Traditional TCM extraction methods often rely on methods such as decoction, maceration, or percolation. While these methods can extract the active ingredients of TCM to a certain extent, they have many shortcomings. First, in traditional methods, the medicinal materials are usually directly placed into an extraction vessel, mixed with a solvent, and then heated for extraction. After extraction, the mixture of medicinal residues and solvent needs to undergo complex filtration and centrifugation steps to separate the medicinal residues. This process is not only time-consuming and labor-intensive, but also easily results in the loss of active ingredients.

[0003] To overcome these shortcomings, extensive research and innovation has been conducted in the field of traditional Chinese medicine extraction equipment in recent years. Among them, hot reflux extraction technology has attracted considerable attention due to its ability to fully utilize solvents and improve extraction efficiency. However, existing hot reflux extraction equipment still has drawbacks when it comes to recovering medicinal residues. For one thing, the mixture of medicinal residues and solvent is difficult to separate directly within the extraction tank. Furthermore, even when the medicinal residues are separated through filtration or other methods, the accumulation and difficulty of cleaning them often increase production costs. Summary of the Invention

[0004] In view of the above problems, the purpose of the present invention is to provide a traditional Chinese medicine hot reflux extraction and concentrator to solve the problems that the mixture of existing medicinal residues and solvents is difficult to separate directly in the extraction tank and that separating the medicinal residues increases the production burden.

[0010] In order to ensure the smooth rotation of the spindle;

[0011] As a further improvement of the above technical solution: a nylon block is mounted on the connecting shaft between the main shaft and the support seat.

[0016] In order to prevent the medicinal materials in the isolation box from leaking out through the slots;

[0017] As a further improvement of the above technical solution: a filter structure is provided in the slot.

[0018] The beneficial effect of this improvement is that the filter can effectively prevent the medicinal materials from leaking out.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0031] like Figure 1—3 shows: a traditional Chinese medicine hot reflux extraction and concentrator, comprising an upper tank body 1 and a main shaft 4, wherein the main shaft 4 extends into the upper tank body 1 and rotates with the upper tank body 1, the inner side of the upper tank body 1 is connected to a support frame 7, the main shaft 4 is rotatably inserted into the support frame 7, and the end of the main shaft 4 located outside the upper tank body 1 can be connected to a rotary drive device to drive the main shaft 4 to rotate. The bottom end of the main shaft 4 is connected to an isolation box 6, and the isolation box 6 includes a lower shell 61 and an upper shell 62 connected by bolts. A folding blade agitator 5 is installed on the main shaft 4 located above the support frame 7. The bottom end of the upper tank body 1 is connected to the lower tank body 2 by bolts, and a driving mechanism 3 for driving the lower tank body 2 to dock and separate with the upper tank body 1 is connected between the upper tank body 1 and the lower tank body 2. The medicinal materials can be isolated and placed inside the isolation box 6 to facilitate the separation and removal of the medicinal residue after the concentration is completed; the isolation box 6 that rotates synchronously with the main shaft 4 cooperates with the water flow delivered by the folding blade stirrer 5 to efficiently contact and mix with the solvent, thereby improving the dissolution efficiency; the lower tank body 2 that is opened by the driving mechanism 3 is convenient for personnel to take and place the medicinal residue.

[0032] The support frame 7 includes a support seat 71 and a support rod 72. The support rod 72 is fixedly connected to the inner wall of the upper tank body 1. The support seat 71 is arranged in the middle of the support rod. The bottom end of the main shaft 4 is formed with a connecting shaft 41, and the connecting shaft 41 is inserted into the support seat 71. The support frame 7 can provide axial support for the main shaft 4, effectively ensuring the rotation stability of the main shaft 4 with an isolation box 6 installed at the bottom. A nylon block 73 is set on the connecting shaft 41 between the main shaft 4 and the support seat 71. The low friction coefficient of the nylon block 73 can effectively reduce the friction resistance between the main shaft 4 and the support frame 7. A plurality of slots 64 are opened on the lower shell 61 and the upper shell 62 along the axial direction of the main shaft 4. The axial flow generated by the folding blade agitator 5 when it rotates can pass through the slots 64 in the isolation box 6 from bottom to top, fully contact and mix with the medicinal materials in the isolation box 6, and improve the dissolution efficiency of the medicinal materials. A filter structure is provided in the slot 64, and the filter in 65 can effectively prevent the medicinal materials from leaking out. A plurality of screws 63 are provided on the bottom surface of the shell 62, and a plurality of through holes for inserting the screws 63 are opened on the lower shell 61. The screws 63 are threadedly connected with nuts, and the lower shell 61 and the upper shell 62 can be firmly connected by a plurality of bolt structures. The driving mechanism 3 includes a cylinder 33, and the two ends of the cylinder 33 are respectively rotated to connect the upper connecting plate 31 and the lower connecting plate 32 through a pin shaft. The upper connecting plate 31 and the lower connecting plate 32 are respectively installed on the sides of the upper tank body 1 and the lower tank body 2. The upper connecting plate 31 is rotatably connected to the lower connecting plate 32 through the pin shaft 34. When the cylinder 33 is extended and retracted, it drives the lower tank body 2 to rotate with the pin shaft 34 as the support, and then drives the lower tank body 2 to rotate to realize the opening or closing of the bottom of the tank body.

[0033] The working principle of this technical solution is as follows: when using this device, the main shaft 4 is driven by a motor in the existing conventional technology, and the corresponding pipes, heat exchangers and valves on the upper tank body 1 and the lower tank body 2 are also connected according to process requirements; when it is necessary to put in medicinal materials, the operator will remove the bolts connecting the upper tank body 1 and the lower tank body 2, control the extension of the oil cylinder 33, and make the oil cylinder 33 drive the lower connecting plate 32 to rotate with the pin shaft 34 as the support, thereby opening the lower tank body 2, and the operator will remove the nut on the screw 63 to separate the lower shell 61 from the upper shell 62, and then put the medicinal materials into the lower shell 61, and then connect the lower shell 61 and the upper shell through the bolt structure. 62, control the oil cylinder 33 to shrink and reset, and tighten the connecting bolts between the upper tank body 1 and the lower tank body 2, and then inject the solution into the tank body for heating, extraction and concentration; during the concentration process, the main shaft 4 rotates under the drive of the motor, and then the folding-blade agitator 5 and the isolation box 6 rotate synchronously, and the support frame 7 can fully ensure the stability of the rotation of the main shaft 4. When the isolation box 6 rotates, the medicinal materials inside are in contact with the water flow in rotation, and when the folding-blade agitator 5 rotates, the water flow moves in the axial direction of the main shaft 4, further improving the dissolution effect with the medicinal materials; after the concentration is completed, the medicinal liquid is transferred to the next process equipment, and then the lower tank body 2 is opened, and the upper shell 62 is removed to take out the medicinal residue.
