Description

Technical Field

[0001] The utility model relates to the technical field of plant extraction, in particular to a plant extract filtering component. Background Art

[0002] Plant extracts are products made from plants as raw materials. According to the needs of the final product, they are extracted through a physical and chemical extraction and separation process to obtain and concentrate one or more active ingredients in the plant without changing the structure of the active ingredients.

[0003] During the extraction process, plants are often filtered using a filtering device to separate solids from liquids and remove solid impurities. For example, patent application number CN201110192518.6 discloses a method for preparing high-purity betulin, wherein the extraction steps include dissolving the crude product in an ethanol aqueous solution, heating it to dissolve, and then filtering it while hot to remove insoluble impurities.

[0004] For plant extracts such as the above-mentioned betulin that require solid-liquid separation through filtering operations, when filtering the solid-liquid mixture, the solid-liquid mixture is first added to the liquid inlet pipe on the filtering device, and then introduced into the filtering device through the liquid inlet pipe. Due to the limited diameter of the liquid inlet pipe, when the solid-liquid mixture is filtered, the mixture only falls to a smaller area directly below the mouth of the liquid inlet pipe, so that the insoluble solid impurities are only distributed in a smaller area of ​​the filter screen and cannot be distributed in the entire filter screen. When the smaller area of ​​the filter screen is blocked, the entire filter screen needs to be manually removed for cleaning or replacement, but in fact other areas of the filter screen are not blocked, resulting in low utilization of the filter screen; and when the filter screen is cleaned or replaced, the solid-liquid separation operation time will be increased, which seriously affects the separation efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a plant extract filtering component, which can increase the distribution area of ​​insoluble solid impurities on the filter screen, thereby greatly prolonging the clogging time of the filter screen, thereby reducing the number of times the filter screen is cleaned or replaced, reducing the solid-liquid separation time, and thereby improving the solid-liquid separation efficiency.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A plant extract filtering component comprises a filtering box and a filtering net arranged inside the filtering box; in addition, the filtering component also comprises a feeding box arranged inside the filtering box and capable of horizontal displacement along a direction perpendicular to its length direction, a telescopic tube connected to the feeding box, and a feeding pipe connected to the telescopic tube; the feeding pipe is connected to the outside at one end away from the telescopic tube; and a plurality of discharge ports are arranged at the bottom end of the feeding box along the length direction.

[0008] Preferably, a hydraulic rod is provided on the inner wall of the filter box, and a telescopic end of the hydraulic rod is connected to the feed box; and both ends of the feed box are movably connected to the inner wall of the filter box.

[0009] Preferably, sliding blocks are provided at both ends of the feed box, and the inner wall of the filter box is provided with a horizontal sliding groove that slidably cooperates with the sliding blocks.

[0010] Preferably, the side wall of the feed box is arranged to be inclined downward along the direction of the discharge port.

[0011] Preferably, the filter box includes a top cover and a box body, the top cover includes a top plate and a surrounding plate arranged at the edge of the top plate; the feed box, feed pipe and telescopic pipe are all arranged on the top cover; the feed box is movably connected to the surrounding plate.

[0012] Preferably, the outer wall of the enclosure and the outer wall of the box body are both provided with a plurality of matching limit blocks, and the matching limit blocks are connected by bolts.

[0013] Preferably, the inner wall of the filter box is provided with a placement ring for placing the filter screen, and the filter screen is magnetically connected to the placement ring.

[0014] Preferably, a pull rod is provided on the top of the filter screen.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] By providing a feed box and a telescopic tube connected to the feed box, and the feed pipe connected to the telescopic tube, after the solid-liquid mixture is added to the feed pipe, the solid-liquid mixture can enter the feed box along the telescopic tube, and then fall onto the filter net along multiple outlets in the feed box to achieve the filtering purpose; at the same time, by making the feed box horizontally displace along a direction perpendicular to its length direction, the solid-liquid mixture can move with the movement of the feed box, and then fall onto the entire filter net to the greatest extent, thereby increasing the distribution area of ​​the insoluble solids on the filter net, and thereby reducing the clogging probability of the filter net. Compared with the technical defect in the prior art that the filter net needs to be removed for cleaning or replacement when a small area of ​​the filter net is blocked, the utility model can reduce the frequency of removing the filter net, thereby reducing the solid-liquid separation time and improving the solid-liquid separation efficiency.

[0022] Below in conjunction with the attached Figures 1 to 4 , the technical solutions in the embodiments of the utility model are clearly and completely described, but the protection scope of the utility model is not limited to the following.

[0023] Example 1

[0024] A plant extract filtration component, such as Figure 1 and Figure 4 As shown, it includes a filter box 100 and a filter screen 110 disposed inside the filter box 100; in addition, as shown Figure 1 and Figure 2 As shown, the filter assembly further includes a feed box 120 disposed inside the filter box 100 and capable of horizontal displacement in a direction perpendicular to its length direction, a telescopic tube 130 connected to the feed box 120, and a feed pipe 140 connected to the telescopic tube 130; one end of the feed pipe 140 away from the telescopic tube 130 is in communication with the outside; Figure 3 As shown, the bottom end of the feed box 120 is provided with a plurality of discharge ports 150 along the length direction. Figure 1 As shown, the feed pipe 140 is arranged at the top of the filter box 100. In actual implementation, a vacuum pump is often arranged on the side wall of the filter box 100 and below the filter screen 110 (not shown in the prior art). Figure 1 As shown, the inner wall of the filter box 100 is provided with a hydraulic rod 160, and the telescopic end of the hydraulic rod 160 is connected to the feed box 120; the two ends of the feed box 120 are movably connected to the inner wall of the filter box 100. Further, the two ends of the feed box 120 are provided with sliders 170, and the inner wall of the filter box 100 is provided with a horizontal slide groove 180 that slidably cooperates with the slider 170.

[0025] Working principle: Add the solid-liquid mixture to be filtered into the feed pipe 140. During this process, it is necessary to turn on the vacuum pump to form a vacuum in the filter box 100 to ensure that the solid-liquid mixture can be smoothly added to the filter box 100. After that, turn on the hydraulic rod 160. Under the action of the hydraulic rod 160, the slider 170 slides in the horizontal slide 180, and then the feed box 120 slides along the length direction of the horizontal slide 180, that is, the left and right direction. During the left and right movement, the solid-liquid mixture will gradually fall onto the surface of the entire filter screen 110, and will be quickly filtered under the action of the filter screen 110. After filtration, the filtrate falls to the bottom of the filter box 100 and is discharged from the discharge pipe set on the side wall of the filter box 100. In order to reduce the residue of the filtrate, the bottom wall of the filter box 100 is tilted downward along the direction of the discharge pipe.

[0026] Through the synergistic effect of the above-mentioned devices, the distribution area of ​​the insoluble solids on the filter screen 110 can be increased, thereby reducing the clogging probability of the filter screen 110, thereby reducing the frequency of removing the filter screen 110, thereby reducing the solid-liquid separation time and improving the solid-liquid separation efficiency.

[0027] Further, based on Example 1, the side wall of the feed box 120 is arranged to be inclined downward along the direction of the discharge port 150. Such an arrangement can reduce the residual solid-liquid mixture on the bottom wall of the feed box 120.

[0028] Further, on the basis of Example 1, the filter box 100 includes a top cover 101 and a box body 102, the top cover 101 includes a top plate and a surrounding plate arranged at the edge of the top plate; the feed box 120, the feed pipe 140 and the telescopic pipe 130 are all arranged on the top cover 101; the feed box 120 is movably connected to the surrounding plate. In this solution, by providing the top cover 101, when the filter screen 110 is blocked, the blocked filter screen 110 can be removed by opening the top cover 101, and the operation is extremely simple.

[0029] Further, such as Figure 4 As shown, the outer wall of the enclosure and the outer wall of the box body 102 are both provided with a plurality of matching stop blocks 200, and the matching stop blocks 200 are connected by bolts 210. In this solution, by providing the stop blocks 200 and the bolts 210, it is convenient to fix the top cover 101 and the box body 102, so that the inside of the filter screen 110 is in a sealed state as a whole, thereby solving the technical problem that some plant extracts are easily oxidized after contacting the air.

[0030] Further, such as Figure 1As shown, the inner wall of the filter box 100 is provided with a placement ring 220 for placing the filter screen 110, and the filter screen 110 is magnetically connected to the placement ring 220 (magnetic connection is a prior art, and its working principle is not described in detail here). By providing the placement ring 220, it is convenient to place the filter screen 110, and by making the filter screen 110 and the placement ring 220 magnetically connected, the two can be detachably connected.

[0031] Further, such as Figure 1 As shown, a pull rod 230 is provided at the top of the filter 110. In this solution, by providing the pull rod 230, when the filter 110 is removed from the placement ring 220, the pull rod 230 can be directly pulled upward, thereby improving the convenience of removing the filter 110.
