Description

Technical Field

[0001] This utility model relates to the field of plant extraction equipment technology, and in particular to a plant extraction concentrator. Background Technology

[0002] Plant extract concentrators are devices used to extract active ingredients (such as polyphenols, flavonoids, alkaloids, etc.) from plant raw materials and to concentrate the extract. They transfer the target components in plants to solvents (such as water, ethanol, etc.) through physical or chemical means, and remove the solvents through evaporation and other technologies to achieve the enrichment of active ingredients.

[0003] Plant extract concentrators are mainly barrel-shaped structures. Plant raw materials are put into the barrel-shaped structure for extraction. The bottom cover of the plant extract concentrator can be opened to discharge the solid raw materials inside. A lot of residue will stick to the inner wall of the plant extract concentrator. The existing water flushing cleaning method is inefficient and requires a long time for each cleaning, resulting in long downtime. Summary of the Invention

[0004] This utility model provides a plant extract concentrator. Through the synchronous rotation of the inner and middle rotating shafts, the upper scraper removes the residue adhering to the inside of the main tank, and the lower scraper removes the residue adhering to the inside of the filter screen. The lower scraper scrapes the filter screen to remove fibrous or colloidal residues. At the same time, the cleaning nozzles perform three-dimensional rinsing of the inside of the main tank. In conjunction with the mechanical scraping, the overall cleaning time is shortened from 120 minutes in the traditional process to 30 minutes.

[0005] This utility model provides a plant extract concentrator, specifically including a main tank, a lower sealing cover, and an inner rotating shaft. The bottom of the main tank is hinged to the lower sealing cover. The top of the inner side of the main tank is rotatably connected to the upper end of the inner rotating shaft.

The steam pipe is used to export steam during concentration. The bottom outer side of the main tank is connected and fixed with a lower liquid outlet. The top of the inner side of the main tank is fixedly provided with a lower annular water pipe. The bottom of the lower annular water pipe is provided with a ring array of cleaning nozzles. The cleaning nozzles have a fan-shaped spray structure. When the cleaning nozzles are activated, they spray water to perform three-dimensional rinsing of the inside of the main tank. An inner sealing ring is fixedly provided on the lower inner side of the main tank.

[0006] Furthermore, a filter screen frame is fixedly connected to the top of the lower sealing cover, a central rotating shaft is rotatably connected to the middle of the lower sealing cover, a drive motor is fixedly connected to the bottom outer side of the lower sealing cover, lower scraper strips are fixedly arranged in a ring array on the outer side of the central rotating shaft, an upper connecting spline is provided on the top of the central rotating shaft, the upper connecting spline is a hexagonal prism structure, and the arc-shaped narrowing structure at the top of the upper connecting spline facilitates quick alignment with the groove at the lower end of the inner rotating shaft. The outer side of the lower sealing cover is rotatably connected to the telescopic rod of the outer telescopic cylinder, and the outer telescopic cylinder is hydraulically driven.

[0007] Furthermore, the tail end of the external telescopic cylinder is rotatably connected to the main tank body, the main shaft and the intermediate shaft of the drive motor are fixedly connected by a coupling, the top of the filter screen frame has filter screen holes, the lower part of the filter screen frame has through holes at the corresponding position of the lower liquid outlet, and the top of the lower scraper slides in contact with the top of the inner side of the filter screen frame.

[0008] Furthermore, when the lower sealing cover and the main tank are closed, the sealing rings at the top of the filter screen frame and the bottom of the inner sealing ring fit together and seal. The filter screen frame has a cylindrical structure with evenly distributed filter holes at the top. The lower liquid outlet is connected to the lower part of the filter screen frame, and the concentrated liquid inside the main tank is filtered to remove solids through the filter screen frame.

[0009] Furthermore, an upper scraper is fixed to the outer annular array of the inner rotating shaft, and a lower protruding strip is fixed to the lower annular array of the inner rotating shaft.

[0010] Furthermore, the lower convex strip is located above the filter screen frame. The lower convex strip disperses the material gathered at the top of the filter screen frame, preventing the flow of solvent from causing the material to concentrate and clog the filter screen frame. The upper scraper slides in close contact with the inside of the main tank.

[0011] Furthermore, when the lower sealing cover and the main tank are closed, the lower ends of the upper connecting spline and the inner rotating shaft are slidably connected.

A lower liquid outlet 103 is connected and fixed to the outer bottom of the main tank 1. A lower annular water pipe 104 is fixedly installed on the top inner side of the main tank 1. A cleaning nozzle 105 is arranged in a circular array at the bottom of the lower annular water pipe 104. The cleaning nozzle 105 has a fan-shaped spray structure. 05. Start water spraying inside the main tank 1 for three-dimensional rinsing. An inner sealing ring 106 is fixedly installed on the lower inner side of the main tank 1. The bottom of the main tank 1 is hinged to a lower sealing cover 2. A filter screen frame 201 is fixedly connected to the top of the lower sealing cover 2. A central rotating shaft 202 is rotatably connected to the middle of the lower sealing cover 2. A drive motor 204 is fixedly connected to the bottom outer side of the lower sealing cover 2. Lower scraper strips 203 are fixed in a ring array on the outer side of the central rotating shaft 202. An upper connecting spline 205 is provided on the top of the central rotating shaft 202. The upper connecting spline 205 is a hexagonal prism structure. The upper part of the spline 205 has an arc-shaped narrowing structure, which facilitates quick alignment with the groove at the lower end of the inner rotating shaft 3. The outer side of the lower sealing cover 2 is rotatably connected to the telescopic rod of the outer telescopic cylinder 206. The outer telescopic cylinder 206 is hydraulically driven. When the lower sealing cover 2 and the main tank 1 are closed, the sealing rings at the top of the filter screen frame 201 and the bottom of the inner sealing ring 106 are sealed together. The filter screen frame 201 has a cylindrical structure with evenly distributed filter holes at the top. The lower liquid outlet 103 is connected to the lower part of the filter screen frame 201. The concentrated liquid inside the main tank 1 is filtered by the filter screen frame 201. The solids are filtered by the filter screen 201 and the liquid is discharged through the lower outlet 103. When the lower sealing cover 2 and the main tank 1 are closed, the upper connecting spline 205 and the lower end of the inner rotating shaft 3 are slidably connected. The upper connecting spline 205 and the inner rotating shaft 3 are slidably connected to achieve synchronous circumferential rotation. Through the rotation of the drive motor 204, the inner rotating shaft 3 and the middle rotating shaft 202 are synchronously rotated. The top of the inner side of the main tank 1 and the upper end of the inner rotating shaft 3 are rotatably connected. The outer side of the inner rotating shaft 3 is fixed with an upper scraper 301 in an annular array, and the lower part of the inner rotating shaft 3 is fixed with a lower protrusion 302 in an annular array.

[0019] In this embodiment, the tail end of the external telescopic cylinder 206 is rotatably connected to the main tank 1, the main shaft of the drive motor 204 and the intermediate shaft 202 are fixedly connected by a coupling, the top of the filter screen frame 201 is a filter screen hole, and the lower part of the filter screen frame 201 has a through hole at the corresponding position of the lower liquid outlet 103. The top of the lower scraper 203 slides against the top of the inner side of the filter screen frame 201, and the lower scraper 203 removes the residue adhering to the inside of the filter screen frame 201.

[0020] In this embodiment, the lower protrusion 302 is positioned above the filter screen frame 201. The lower protrusion 302 disperses the material gathered at the top of the filter screen frame 201, preventing the flow of solvent from causing the material to concentrate and clog the filter screen frame 201. The upper scraper 301 slides in close contact with the inside of the main tank 1, and the upper scraper 301 removes the residue adhering to the inside of the main tank 1.

[0021] In this second embodiment, based on the first embodiment, a through hole is opened on the side of the lower sealing cover plate 2 and the main tank 1 facing the hinge. The through hole of the filter screen frame 201 is at its lowest point in the open state. Solid residues inside the filter screen frame 201 are discharged outward through the through hole of the filter screen frame 201, reducing the difficulty of discharging small residues inside the filter screen frame 201.

[0022] The working principle of this embodiment is as follows: The lower part of the main tank 1 is suspended. Plant materials and solvents are poured into the main tank 1 through the feeding pipe 101. The main tank 1 soaks and extracts the plant materials and solvents inside, and then heats and evaporates them for concentration. The rotation of the upper scraper 301 promotes the accelerated fusion of plants and solvents inside the main tank 1. The concentrated liquid inside the main tank 1 is filtered by the filter screen 201 to remove solids. The liquid filtered by the filter screen 201 is discharged through the lower outlet 103. After the solution inside the main tank 1 is discharged, the outer telescopic cylinder 206 extends, causing the lower sealing cover 2 to rotate downward and open. The lower sealing cover 2, the central rotating shaft 202, and the filter screen 201 open downward simultaneously, and the bottom opening of the main tank 1 is connected to the outside. The plant materials inside the main tank 1 are discharged downward. When the inside of the main tank 1 is being cleaned, the outer telescopic cylinder 206 shortens, causing the lower sealing cover 2 to rotate and close the main tank 1. The upper connecting spline 205 and the inner rotating shaft 3 slide into... The inner rotating shaft 3 and the middle rotating shaft 202 rotate synchronously through the rotation of the drive motor 204. The inner rotating shaft 3 and the upper scraper 301 rotate synchronously. The upper scraper 301 removes the residue adhering to the inside of the main tank 1. The upper scraper 301 adopts an arc-shaped blade design, combined with the flexible fit of the polytetrafluoroethylene sealing strip, which can remove ≥95% of the residue adhering to the inner wall of the main tank 1. The middle rotating shaft 202 and the lower scraper 203 rotate synchronously. The lower scraper 203 cleans the filter screen. The residue adhering inside the filter frame 201 is removed. The lower scraper 203 applies a scraping pressure of 0.2-0.5 MPa to the inside of the filter frame 201, effectively removing fibrous or colloidal residues between the filter holes, restoring the filter permeability to over 98%. At the same time, the cleaning nozzle 105 is activated to spray water into the main tank 1 for three-dimensional rinsing. The coordinated action of rinsing and mechanical scraping reduces the overall cleaning time from 120 minutes in the traditional process to 30 minutes, and reduces downtime losses by 75%. During the solvent discharge process, the lower convex strip 302 rotates synchronously with the inner rotating shaft 3. The rotating lower convex strip 302 disperses the material gathered at the top of the filter screen 201 during the filtration process, preventing the flow of solvent from causing the material to concentrate and block the filter screen 201, ensuring the smooth flow of the filter screen 201, and effectively ensuring the continuity and stability of the extraction and concentration process. The upper scraper 301 rotates synchronously, driving the material to rotate. The rotation and swaying of the material accelerates the solid-liquid separation and speeds up the separation efficiency of solvent and material.
