The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] First embodiment

[0021] See also Figure 1 to Figure 4 ,in Figure 1 is a schematic diagram of the overall structure of the first embodiment, Figure 2 is a cross-sectional view of the internal structure of the feed assembly of the first embodiment, Figure 3 yes Figure 2 A magnified view of the local structure at A.

[0022] The utility model provides a plant polyphenol extraction and purification device: comprising a centrifugal extractor 101, a base 102, a feed pipe 103 and a feed assembly, wherein the feed assembly comprises a feed hopper 104, a temporary storage frame 105, an opening and closing plate 106, a first torsion spring 107, a second torsion spring 108, a weighing plate 109, an indicator 110, a reset spring 111 and a sealing strip 112. The above-mentioned solution solves the problem that when extracting plant polyphenols in the prior art, the extracting liquid needs to be weighed before adding in the centrifugal extractor, which is troublesome to operate and leads to low extraction efficiency.

[0023] According to this specific embodiment, the centrifugal extractor 101 is connected to the base 102 and is located above the base 102. The feed pipe 103 is connected to the centrifugal extractor 101. The feed assembly is arranged on the feed pipe 103. The extract is added to the feed assembly, and then the extract passes through the feed pipe 103 and enters the centrifugal extractor 101. The centrifugal extractor 101 extracts the extract.

[0024] The feed hopper 104 is connected to the feed pipe 103 and is located at the end of the feed pipe 103 away from the centrifugal extractor 101. The temporary storage frame 105 is movably connected to the feed hopper 104 and is located in the temporary storage frame 105. The two ends of the first torsion spring 107 are respectively fixedly connected to the feed hopper 104 and the temporary storage frame 105. The opening and closing plate 106 is movably connected to the temporary storage frame 105 and is located in the temporary storage frame 105. The two ends of the second torsion spring 108 are respectively fixedly connected to the feed hopper 104 and the temporary storage frame 105. The temporary storage frame 105 is fixedly connected to the opening and closing plate 106, the weighing plate 109 is arranged in the temporary storage frame 105, the indicator 110 is fixedly connected to the feed hopper 104 and is located on the outer side wall of the feed hopper 104, and the indicator 110 is connected to the weighing plate 109. When the extract is subjected to plant polyphenol extraction, the extract is stored in the temporary storage frame 105, and the weighing plate 109 weighs the extract in the temporary storage frame 105. The weight of the extract is measured by the indicator. Table 110 shows that the support force of the first torsion spring 107 is set according to the weight of the extract. When the first torsion spring 107 reaches the specified support force, the temporary storage frame 105 rotates downward in the feed hopper 104, the first torsion spring 107 is deformed, and the temporary storage frame 105 tilts. Under the gravity of the extract, the extract pushes the opening and closing plate 106 to move on the temporary storage frame 105, and the second torsion spring 108 is deformed. At this time, the temporary storage frame 105 is tilted. The extract will enter the feed hopper 104, and then enter the centrifugal extractor 101 through the feed pipe 103 for extraction. After the extract in the temporary storage frame 105 is discharged, the temporary storage frame 105 is reset under the action of the first torsion spring 107, and the opening and closing plate 106 is reset in the temporary storage frame 105 under the action of the second torsion spring 108. Through the above method, it is achieved that there is no need to weigh separately before adding, which saves time, is easy to operate, and improves extraction efficiency.

[0025] Secondly, the two ends of the return spring 111 are fixedly connected to the temporary storage frame 105 and the feed hopper 104 respectively, and are located in the feed hopper 104. By arranging the return spring 111 between the temporary storage frame 105 and the feed hopper 104, the return spring 111 expands and contracts as the temporary storage frame 105 moves. The return spring 111 can increase the return effect of the temporary storage frame 105. After the liquid in the temporary storage frame 105 is drained, it is quickly reset in the feed hopper 104 under the action of the return spring 111.

[0026] At the same time, the temporary storage frame 105 has a sealing groove 113, the sealing strip 112 is fixedly connected to the opening and closing plate 106 and matched with the sealing groove 113. By arranging the sealing strip 112 on the opening and closing plate 106, the sealing strip 112 is matched with the sealing groove 113 on the temporary storage frame 105, thereby improving the sealing effect when the opening and closing plate 106 and the temporary storage frame 105 are closed.

[0027] When the extract is subjected to plant polyphenol extraction, the extract is stored in the temporary storage frame 105, the weighing plate 109 weighs the extract in the temporary storage frame 105, and the weight of the extract is displayed on the indicator 110 for easy viewing by personnel. The supporting forces of the first torsion spring 107 and the reset spring 111 are set according to the weight of the extract. When the first torsion spring 107 reaches the specified supporting force, the temporary storage frame 105 rotates downward in the feed hopper 104, the first torsion spring 107 is deformed, the reset spring 111 is compressed, and the temporary storage frame 105 is tilted. Under the gravity of the extract, the extract pushes the opening and closing plate 106 to move on the temporary storage frame 105, and the second torsion spring 108 is deformed. At this time, the temporary storage frame 105 The extract in the temporary storage frame 105 will enter the feed hopper 104, and then enter the centrifugal extractor 101 through the feed pipe 103 for the extraction process. After the extract in the temporary storage frame 105 is discharged, the temporary storage frame 105 is reset under the action of the first torsion spring 107 and the reset spring 111, and the opening and closing plate 106 is reset in the temporary storage frame 105 under the action of the second torsion spring 108; by arranging the sealing strip 112 on the opening and closing plate 106, the sealing strip 112 is adapted to the sealing groove 113 on the temporary storage frame 105, thereby improving the sealing effect of the opening and closing plate 106 and the temporary storage frame 105 when they are closed. Through the above method, it is achieved that there is no need to weigh separately before adding, which saves time, is easy to operate, and improves the extraction efficiency.

[0028] Second embodiment

[0029] See also Figure 4 ,in Figure 4It is a schematic diagram of the overall structure of the second embodiment.

[0030] On the basis of the first embodiment, the plant polyphenol extraction and purification device of the utility model further includes a fixing component, which includes two fixing cylinders 201 , two jackets 202 , two sliding blocks 203 and two rubber pads 204 .

[0031] The fixing assembly is disposed on the base 102 and is adapted to the centrifugal extractor 101. The centrifugal extractor 101 can be firmly fixed on the base 102 by the fixing assembly to prevent the centrifugal extractor 101 from vibrating and moving on the base 102 when working.

[0032] The two fixed cylinders 201 are fixedly connected to the base 102 and symmetrically arranged above the base 102. The two jackets 202 are fixedly connected to the output ends of the corresponding fixed cylinders 201. The base 102 has two sliding grooves 205. Each of the sliding blocks 203 is fixedly connected to the corresponding jackets 202 and is located in the corresponding sliding grooves 205. The centrifugal extractor 101 is located between the two jackets 202. When the centrifugal extractor 101 is placed on the base 102, the centrifugal extractor 101 is located between the two jackets 202 on the base 102. Then, the two fixed cylinders 201 are started, and the two fixed cylinders 201 respectively drive the jacket 202 to approach the outer wall of the centrifugal extractor 101, and at the same time, the slider 203 under the jacket 202 slides in the sliding groove 205 of the base 102 until the two jackets 202 clamp the centrifugal extractor 101 on the base 102, so that the centrifugal extractor 101 is fixed on the base 102. In this way, the centrifugal extractor 101 can be firmly fixed on the base 102 to prevent the centrifugal extractor 101 from vibrating and moving on the base 102 when working.

[0033] The two rubber pads 204 are respectively fixedly connected to the corresponding jackets 202 and are respectively located on the inner walls of the jackets 202. By arranging the rubber pads 204 on the inner walls of the jackets 202, the rubber pads 204 increase the friction between the jacket 202 and the outer wall of the centrifugal extractor 101, so that the centrifugal extractor 101 can be fixed more stably.

[0034] When the centrifugal extractor 101 is placed on the base 102, the centrifugal extractor 101 is placed between the two jackets 202 on the base 102, and then the two fixed cylinders 201 are started. The two fixed cylinders 201 drive the jackets 202 to approach the outer wall of the centrifugal extractor 101 respectively, and at the same time, the slider 203 under the jacket 202 slides in the sliding groove 205 of the base 102 until the two jackets 202 push the centrifugal extractor 101. The centrifugal extractor 101 is clamped on the base 102 to be fixed on the base 102; by arranging the rubber pad 204 on the inner wall of the jacket 202, the rubber pad 204 increases the friction between the jacket 202 and the outer wall of the centrifugal extractor 101, so that the centrifugal extractor 101 can be fixed more stably. In this way, the centrifugal extractor 101 can be firmly fixed on the base 102 to prevent the centrifugal extractor 101 from vibrating and moving on the base 102 when working.
