Description

Technical Field

[0001] This utility model relates to the technical field of rhodioloside removal equipment, specifically a rhodioloside removal equipment. Background Technology

[0002] Rhodioloside is one of the main active ingredients of plants in the Rhodioloside genus. Rhodioloside can improve the body's ability to adapt to hypoxic environments by enhancing cellular aerobic metabolism, regulating the expression of hypoxia-inducible factors, improving tissue oxygen utilization, and reducing lactic acid accumulation and oxidative damage caused by hypoxia. After extraction, the raw material of Rhodioloside contains a large number of impurities, including cellulose, starch, protein, tannins, pigments, polysaccharides, and inorganic salts. These impurities will affect the subsequent purification efficiency and product purity.

[0003] Currently, the product fermentation broth passes through a ceramic membrane. During the separation of impurities in the feed liquid, a feed pump and a circulation pump are used to pass small molecule solute particles from the high-pressure feed liquid side through the membrane to the low-pressure side, where the permeate is collected. Meanwhile, high molecular weight impurities are trapped by the membrane, causing their concentration to increase on the trap side. Once a certain concentration is reached, purified water is used for top washing. The permeate is collected according to the feed liquid content, and the trap liquid is discharged. This process can lead to partial blockage of the membrane pores, slowing down the feed liquid flow rate, and ultimately making the ceramic membrane difficult to clean. Utility Model Content

The holes are interconnected. The feed end of the feed pipe is connected to the pipe used to transport the rhodioloside solution. The output end of the through hole is connected to the feed end of the disc centrifuge through a connecting piece. The inner cavity of the filter mounting hole is provided with a preliminary filter element for preliminary filtration of the rhodioloside solution. When the filter mounting hole coincides with the through hole, the solution enters the connecting piece sequentially through the through hole and the preliminary filter element. Rotating the filter turntable makes different filter mounting holes coincide with the through hole, thereby switching the preliminary filter element.

A groove is opened in the upper opening of each set of filter mounting holes. A magnetic suction ring for adsorbing the corresponding side mounting ring is embedded in the inner cavity of each set of grooves.

[0011] As a preferred technical solution, the connecting component includes a guide pipe connected to the lower opening of the through hole, the lower opening of the guide pipe being connected to a second flange, and the feed end of the disc centrifuge being connected to a first flange, the first flange and the second flange being fixedly connected together by bolts and nuts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of a disc centrifuge and a preliminary filter element, increases the throughput of the disc centrifuge, achieving continuous production. Its energy consumption is lower than that of membrane filtration. Furthermore, the maintenance of the disc centrifuge mainly focuses on cleaning the drum and verifying its dynamic balance, making cleaning relatively convenient. The preliminary filter element performs initial filtration of the liquid, reducing the processing burden on the disc centrifuge. When the preliminary filter element needs to be replaced, simply rotate the filter disc to align the different filter mounting holes with the through holes, without interrupting the overall liquid processing flow, ensuring the continuity of liquid processing. The liquid sequentially enters the disc centrifuge through the feed pipe, through holes, preliminary filter element, and connecting element, achieving orderly liquid transport and seamless integration of preliminary filtration and deep impurity removal, thus improving the processing efficiency and impurity removal effect of the rhodiola glycoside liquid.

[0014] 2. This utility model uses a magnetic suction device to insert the filter cartridge into the filter mounting hole, and the filter cartridge opening is also installed via the magnetic suction device, making the installation and disassembly of the filter cartridge more convenient and quick. Furthermore, the magnetic suction installation method not only ensures the stability of the filter cartridge during operation and prevents material leakage, but also allows for easy separation when the filter cartridge needs to be cleaned or replaced, reducing maintenance difficulty and improving equipment maintenance efficiency.

[0015] 3. This utility model, through the setting of positioning groove and positioning rod, sets a positioning groove on the top of the filter turntable. With the positioning rod on the mounting plate and the elastic pusher, it can accurately position after the filter turntable is rotated, ensuring that the filter mounting hole and the through hole are accurately aligned. This avoids material leakage or filtration effect caused by the filter turntable offset. At the same time, the elastic pusher can keep the positioning rod in the positioning groove at all times, ensuring the reliability of positioning. The positioning can be easily released by the pull ring, making the operation simple and improving the accuracy and efficiency of the initial filter element switching. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-3 This embodiment provides a rhodioloside removal device, including a disc centrifuge 100 for filtering rhodioloside liquid. A C-shaped frame 200 is arranged above the disc centrifuge 100, and a through hole 209 is opened on the C-shaped frame 200. The through hole 209 is opposite to the liquid inlet at the center of the disc centrifuge 100. A filter disc 202 is rotatably connected to the inner side of the C-shaped frame 200. The filter disc 202 has several sets of filter mounting holes 204, which are arranged in a circular array, and one set of filter mounting holes 204 coincides with the through hole 209. The top of the C-shaped frame 200 has an inlet... The feed pipe 201 has its inner cavity connected to the through hole 209. The feed end of the feed pipe 201 is connected to the pipeline used to transport the rhodioloside solution. The output end of the through hole 209 is connected to the feed end of the disc centrifuge 100 through a connecting member. The inner cavity of the filter mounting hole 204 is provided with a preliminary filter element for preliminary filtration of the rhodioloside solution. When the filter mounting hole 204 coincides with the through hole 209, the solution enters the connecting member sequentially through the through hole 209 and the preliminary filter element. Rotating the filter turntable 202 makes different filter mounting holes 204 coincide with the through hole 209, thereby realizing the switching of the preliminary filter element.

[0028] Compared to membrane filtration, disc centrifuge 100 increases throughput and achieves continuous production. It also consumes less energy than membrane filtration. Maintenance of the disc centrifuge primarily focuses on cleaning the drum and balancing the dynamic balance, making cleaning relatively convenient. Furthermore, the preliminary filter element performs initial filtration of the liquid, reducing the processing burden on the disc centrifuge 100. When the preliminary filter element needs replacement, simply rotate the filter disc 202 to align the different filter mounting holes 204 with the through holes 209, without interrupting the overall liquid processing flow, ensuring the continuity of liquid processing. The liquid sequentially enters the disc centrifuge 100 through the feed pipe 201, through holes 209, preliminary filter element, and connecting element, achieving orderly liquid transport and seamless integration of preliminary filtration and deep impurity removal, thus improving the processing efficiency and impurity removal effect of the rhodiola glycoside liquid.

[0029] The connecting component includes a guide pipe 203 connected to the lower opening of the through hole 209. A second flange 102 is installed at the lower opening of the guide pipe 203. A first flange 101 is installed at the feed end of the disc centrifuge 100. The first flange 101 and the second flange 102 are fixedly connected together by bolts and nuts. The cooperation of the guide pipe 203, the first flange 101 and the second flange 102 realizes a stable connection between the through hole 209 and the feed end of the disc centrifuge 100. The fixing method of bolts and nuts ensures the sealing of the connection and prevents leakage of liquid. At the same time, the flange connection facilitates the disassembly and assembly of the connecting component and the disc centrifuge 100, which provides convenience for the maintenance and repair of the equipment and ensures that the liquid can be stably delivered to the disc centrifuge 100 for processing.

[0030] The disc centrifuge 100 in this embodiment is a well-known technical means for those skilled in the art. For its specific working principle and structure, please refer to the disc centrifuge with quick installation structure disclosed in CN222551109U. Other details will not be elaborated here.

[0031] The preliminary filter element includes a filter cartridge 207 inserted into each set of filter mounting holes 204. The opening of each set of filter cartridges 207 is installed inside the filter mounting hole 204 by magnetic attachment. With the magnetic attachment, the filter cartridge 207 is inserted into the filter mounting hole 204, and the opening of the filter cartridge 207 is installed by magnetic attachment, making the installation and removal of the filter cartridge 207 more convenient and quick. In addition, the magnetic installation method not only ensures the stability of the filter cartridge 207 during operation and prevents material leakage, but also allows for easy separation when cleaning or replacing the filter cartridge 207, reducing maintenance difficulty and improving equipment maintenance efficiency.

[0032] The magnetic attraction component includes a mounting ring 208 fixedly sleeved on the outer circumference of the opening of each filter cylinder 207. Each mounting ring 208 is respectively embedded in the opening of the corresponding side filter mounting hole 204. The top of each mounting ring 208 is flush with the top of the filter turntable 202. A groove 205 is provided in the upper opening of each filter mounting hole 204. A magnetic ring 206 for attracting the corresponding side mounting ring 208 is embedded in the inner cavity of each groove 205. Through the arrangement of the mounting ring 208 and the magnetic ring 206, the mounting ring 208 and the magnetic ring 206 are attracted to each other. The suction ring 206 secures the filter cartridge 207. The mounting ring 208 is embedded in the filter mounting hole 204 and its top is flush with the top of the filter turntable 202, ensuring the flatness of the surface of the filter turntable 202 and preventing structural protrusions from interfering with operation or liquid flow. At the same time, the magnetic suction ring 206 is embedded in the groove 205, which can stably attract the mounting ring 208, ensuring that the filter cartridge 207 remains firmly installed under the impact of liquid. This also makes the installation and removal of the filter cartridge 207 smoother and further improves the convenience of maintenance.

[0033] The top of the filter turntable 202 has multiple positioning slots 305, which are located inside each set of filter mounting holes 204. A mounting plate 304 is fixedly connected to one end of the C-shaped frame 200. A positioning rod 300 is inserted into the top of one side of the mounting plate 304, and a pull ring 302 is fixedly connected to the top of the positioning rod 300. Below the mounting plate 304, an elastic pusher is provided to push the positioning rod 300 downwards into the corresponding side positioning slot 305 cavity. Through the arrangement of the positioning slots 305 and the positioning rod 300... With the positioning rod 300 and elastic pusher on the mounting plate 304, precise positioning can be achieved after rotating the filter disc 202, ensuring that the filter mounting hole 204 and the through hole 209 are accurately aligned. This avoids material leakage or impact on filtration effect due to the offset of the filter disc 202. At the same time, the elastic pusher ensures that the positioning rod 300 is always inserted into the positioning groove 305, guaranteeing the reliability of positioning. The positioning can be easily released by the pull ring 302, making operation simple and improving the accuracy and efficiency of the initial filter element switching.

[0034] The elastic pusher includes a limiting plate 303 fixedly sleeved on the lower surface of the positioning rod 300. A spring 301 is sleeved on the outer surface of the positioning rod 300, located between the limiting plate 303 and the mounting plate 304. The two ends of the spring 301 contact the bottom of the mounting plate 304 and the top surface of the limiting plate 303, respectively. With the setting of the elastic pusher, the combination of the limiting plate 303 and the spring 301 allows the elastic force of the spring 301 to continuously push the positioning rod 300 downward into the positioning groove 305, ensuring stable positioning. At the same time, the limiting plate 303 can restrict the position of the spring 301, preventing the spring 301 from falling off, ensuring the stable operation of the elastic pusher, and effectively realizing the automatic reset of the positioning rod 300, thus improving the convenience and stability of the positioning operation.

[0035] See Figure 4 Each filter cylinder 207 has a conical filter barrel 210 connected to its bottom inner wall. The opening of the conical filter barrel 210 is set downwards. By connecting the bottom inner wall of the filter cylinder 207 to the downward-facing conical filter barrel 210, the filtration area can be increased, improving the initial filtration effect on the Rhodiola rosea glycoside solution. This can more effectively intercept impurities in the solution. At the same time, the conical structure can also guide the flow of the solution, reduce the retention of the solution during the filtration process, ensure the smoothness of the solution delivery, and improve the filtration efficiency.

[0036] Working principle;

[0037] First, the first flange 101 and the second flange 102 are fixedly connected by bolts and nuts, realizing the stable delivery of the liquid from the preliminary filter to the disc centrifuge 100. When processing the rhodioloside liquid, the liquid first enters the feed pipe 201 through the delivery pipe, and then flows into the through hole 209 opened at the top of the C-shaped frame. Since the through hole 209 coincides with a set of filter mounting holes 204 on the filter turntable 202, the liquid will pass through the through hole 209 and the preliminary filter in the filter mounting hole 204 in sequence. After the preliminary filtration is completed, it enters the disc centrifuge 100 through the guide pipe 203, and the disc centrifuge 100 further removes impurities from the liquid.

[0038] The liquid first enters the filter cartridge 207 for filtration. After each filter cartridge 207 has been used for a certain period of time, the filter disc 202 is rotated to switch filter cartridges 207. The liquid after filtration through the filter cartridge 207 enters the high-speed rotating disc centrifuge 100. In the centrifugal force, the heavier solids are deposited on the drum wall according to their specific gravity. Under the control of the PLC, the solids and a small amount of liquid are discharged from the machine, while the lighter liquid phase flows along the outer conical surface of the disc towards the axis and is discharged from the light liquid outlet, thus achieving the separation of solids and light liquid phase.

[0039] When the filter cartridge 207 needs to be cleaned, pull the pull ring 302 upwards to disengage the positioning rod 300 from the positioning groove 305, thereby releasing the positioning. Then, rotate the filter turntable 202 to make the different filter mounting holes 204 coincide with the through holes 209, so that different preliminary filter elements can be used alternately, and the filter cartridge 207 that needs to be cleaned can be rotated to the outside.

[0040] After rotating the filter turntable 202 and releasing the pull ring 302, the positioning rod 300 will re-insert into the new positioning groove 305 under the action of the spring 301, completing the positioning. When the filter cartridge 207 needs to be removed for cleaning or replacement, simply overcome the attraction force of the magnetic ring 206 and pull the filter cartridge 207 out of the filter mounting hole 204. During installation, align the mounting ring 208 of the filter cartridge 207 with the opening of the filter mounting hole 204, and use the attraction force of the magnetic ring 206 to fix it. The operation is simple and efficient.

[0041] Example 2

[0042] See Figure 5 In this embodiment, a receiving tray 211 is also provided on the lower side of the C-shaped frame 200. The receiving tray 211 receives part of the liquid that leaks between the C-shaped frame 200 and the filter disc 202 and sends it into the residue discharged from the disc centrifuge 100. Purified water is added to dilute it and it is returned to the feed pipe 201 for re-filtration to reduce material loss.
