Description

Technical Field

[0001] This utility model relates to the field of deoxycholic acid production technology, specifically to a device for separating and purifying deoxycholic acid from porcine cholic acid tailings. Background Technology

[0002] The processing of porcine bile acids generates a large amount of byproduct, porcine bile acid tailings. These tailings typically contain deoxycholic acid, a component with high value. To fully utilize resources and increase product added value, these tailings require further processing to effectively separate and purify the deoxycholic acid they contain. A deoxycholic acid separation and purification device for porcine bile acid tailings is designed and applied for this purpose. It aims to recover the target substance from the complex tailings to meet the needs of subsequent production or research.

[0003] However, when traditional separation equipment processes viscous or high-solids porcine bile acid tail residue, its filtration units are prone to rapid clogging due to the accumulation of solid particles, leading to frequent shutdowns for cleaning. This not only affects processing efficiency but also increases maintenance burden. At the same time, most existing devices lack effective integration between the preliminary filtration and fine purification stages, often requiring multiple independent devices to complete the process step by step, making the process relatively cumbersome. Material transfer between each stage may also introduce the risk of loss or contamination. Utility Model Content

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

Detailed Implementation

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.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A device for separating and purifying deoxycholic acid from porcine cholic acid tailings includes a suction pump 101, a first filter cartridge 102, and a second filter cartridge 103. The suction end of the suction pump 101 is provided with a suction connector 104. The pumping end of the suction pump 101 is connected to the input end of the first filter cartridge 102 through a pipe. The discharge end of the first filter cartridge 102 is connected to the input end of the second filter cartridge 103 through a pipe. A first cover 105 is bolted to the top of the first filter cartridge 102. A support cylinder 106 is fixedly provided to the top of the first cover 105. A drive motor 107 is bolted to the top of the support cylinder 106. A drive shaft 108 is provided at the output end of the drive motor 107. Two arc-shaped scrapers 109 are symmetrically installed inside the first filter cartridge 102 through the bottom end of the drive shaft 108. The surface of the arc-shaped scrapers 109 is solid, and the arc surfaces of the arc-shaped scrapers 109 face opposite directions.

[0023] The above scheme utilizes a combination of a suction pump and a suction connector to generate power for continuous suction of porcine bile acid tailings liquid from the raw material source; a multi-stage filtration process can be constructed by connecting the first and second filter cartridges in series; a detachable seal can be achieved at the top of the first filter cartridge by the combination of the first cover and bolts; a rigid structure connecting the first cover and the drive motor can be formed by the support cylinder; rotational power can be transmitted to the inside of the first filter cartridge by the connection between the drive motor and the drive shaft; and two arc-shaped scrapers mounted on the drive shaft with opposite arc surfaces can agitate the fluid and scrape off the deposits on the inner wall of the filter element during rotation.

[0024] In this embodiment, preferably, a filter element frame 110 is bolted to the inside of the first filter cartridge 102. A non-woven filter element 111 is provided inside the filter element frame 110. A metal mesh 112 is attached to the inner side of the non-woven filter element 111 and connected to the filter element frame 110. An arc-shaped scraper 109 is rotatably provided inside the non-woven filter element 111.

[0025] The above scheme provides a core support frame by installing the filter element skeleton inside the first filter cartridge; the non-woven filter element placed inside the filter element skeleton can perform the initial solid-liquid separation task; the metal mesh attached to the inside of the non-woven filter element can enhance the overall impact resistance of the filter element; and the rotating arc-shaped scraper inside the non-woven filter element can maintain the cleanliness of the filter element surface and promote filtration.

[0026] In this embodiment, preferably, a second cover 113 is bolted to the top of the second filter cartridge 103, and a pressure block 114 is fixedly installed at the bottom of the second cover 113. The pressure block 114 is housed inside the second filter cartridge 103, and its bottom end is pressed against the top of the nanofiltration membrane filter element 115.

[0027] The above scheme enables the rapid sealing and opening of the top of the second filter cartridge through the cooperation of the second cover and bolts; the pressure block fixed to the bottom of the second cover can generate a stable downward pressure on the internal filter element.

[0028] In this embodiment, preferably, a discharge connector 116 is fixedly installed at the bottom of the second filter cartridge 103, and a filter outlet connector 117 is fixedly installed on the lower outer side of the second filter cartridge 103. Two slots 118 are symmetrically opened on the bottom surface inside the second filter cartridge 103, which are respectively connected to the discharge connector 116 and the filter outlet connector 117.

[0029] The above scheme allows the permeate to flow out of the system via a discharge connector installed at the bottom of the second filter cartridge; the concentrated target product can be collected via a filter outlet connector installed on the outside of the second filter cartridge; and two slots provided inside the bottom of the second filter cartridge can provide independent channels for different flow paths.

[0030] In this embodiment, preferably, the nanofiltration membrane filter element 115 is inserted into the interior of the second filter cartridge 103, and there is a certain gap between the nanofiltration membrane filter element 115 and the inner wall of the second filter cartridge 103. Two flow guide connectors 119 are symmetrically installed at the bottom end of the nanofiltration membrane filter element 115.

[0031] The above scheme enables molecular-level separation by inserting the nanofiltration membrane cartridge inside the second filter cartridge; a uniform liquid inlet space can be formed by the gap between the nanofiltration membrane cartridge and the inner wall of the second filter cartridge; and two flow guide connectors installed at the bottom of the nanofiltration membrane cartridge can distinguish and deliver two different components.

[0032] In this embodiment, preferably, one of the flow guides 119 communicates with the internal channel of the nanofiltration membrane filter element 115 and is inserted into the slot 118 of the connecting discharge connector, and the other flow guide 119 communicates with the internal interception surface of the nanofiltration membrane filter element 115 and is inserted into the slot 118 of the connecting filter outlet connector 117.

[0033] The above scheme allows the permeate to be directed to the discharge connector by connecting one flow guide connector to the internal channel of the nanofiltration membrane cartridge; and the enriched liquid to be directed to the filtration connector by connecting another flow guide connector to the internal retention surface of the nanofiltration membrane cartridge.

[0034] In this embodiment, a device for separating and purifying deoxycholic acid from porcine cholic acid tailings is used. The suction pump 101 continuously draws raw porcine cholic acid tailings liquid from an external pretreatment device through the suction connector 104 at its suction end. The pumping end of the suction pump 101 delivers the liquid at a certain pressure to the input end of the first filter cartridge 102 via a pipeline. The liquid then enters the interior of the first filter cartridge 102 and fills the internal space of the non-woven fabric filter element 111 supported by the filter element frame 110. The filter element frame 110 and the metal mesh 112 attached to the inner side of the non-woven fabric filter element 111 together ensure the structural stability of the non-woven fabric filter element 111 under fluid pressure and force.

[0035] At the same time, the drive motor 107 fixed on the first cover 105 at the top of the first filter cartridge 102 starts, and the output end of the drive motor 107 drives the drive shaft 108 to rotate. The drive shaft 108 extends into the interior of the first filter cartridge 102, and two solid arc-shaped scrapers 109 with opposite arc surfaces mounted symmetrically at its bottom rotate synchronously inside the non-woven filter element 111. The rotational motion of the arc-shaped scraper 109 has a dual effect: First, the arc-shaped scraper 109 directly agitates the raw liquid, creating eddies and centrifugal tendencies. This dynamic stirring accelerates the radial passage of liquid components through the nonwoven filter element 111 for filtration, while solid particles are trapped inside the nonwoven filter element 111. Second, as the arc-shaped scraper 109 rotates close to the inner wall of the nonwoven filter element 111, its arc surface continuously scrapes and cleans the filter cake or blockages adhering to the filter material surface. This dynamic cleaning process effectively slows down the clogging rate of the nonwoven filter element 111, thereby maintaining a relatively stable filtration flux. The clarified liquid after filtration through the nonwoven filter element 111 passes through the filter element and flows out through a pipe via the discharge end of the first filter cartridge 102, entering the next processing unit.

[0036] The pre-filtered liquid is introduced into the inlet of the second filter cartridge 103 through a pipe. Inside the second filter cartridge 103, the liquid first enters the gap space between the inner wall of the second filter cartridge 103 and the outer surface of the nanofiltration membrane element 115. The second cover 113 is fastened to the top of the second filter cartridge 103 by bolts, and the pressure block 114 fixedly installed at its bottom end then penetrates into the interior of the second filter cartridge 103, firmly pressing the nanofiltration membrane element 115 against the bottom surface inside the second filter cartridge 103. This pressing action ensures the sealing and fixation of the nanofiltration membrane element 115 in the working position.

[0037] Under the continuous pressure of the system feed, the liquid is forced to pass through the membrane surface from the outside of the nanofiltration membrane element 115 and enter the flow channels inside the nanofiltration membrane element 115. The nanofiltration membrane element 115 selectively separates components in the liquid due to its precise nanoscale pore size. Deoxycholic acid molecules and other larger molecules that are retained cannot pass through the nanofiltration membrane and instead collect along the retention surface channels inside the nanofiltration membrane element 115.

[0038] Two symmetrically mounted flow guides at the bottom of the nanofiltration membrane cartridge play a crucial role in flow diversion. One flow guide, which communicates with the internal retention surface of the nanofiltration membrane cartridge, is precisely inserted into a slot at the bottom of the second filter cartridge that connects to the outlet connector. The deoxycholic acid-enriched solution, concentrated and retained by the nanofiltration membrane, is guided through this flow guide to the outlet connector and ultimately discharged for collection. Simultaneously, water molecules and some small solvent molecules successfully permeate through the nanofiltration membrane and enter the internal channel on the other side of the nanofiltration membrane cartridge.

[0039] Another flow guide connector, which communicates with the internal channel of the nanofiltration membrane cartridge, is inserted into a slot at the bottom of the second filter cartridge that connects to the discharge connector. The permeate that has passed through the nanofiltration membrane is then guided through this flow guide connector to the discharge connector and discharged.

[0040] The entire device is powered by a suction pump. The non-woven fabric filter element of the first filter cartridge is connected in series for coarse filtration and anti-clogging pretreatment, and the nanofiltration membrane filter element of the second filter cartridge is used for fine filtration and molecular-level separation. This achieves the goal of continuous and efficient separation and purification of deoxycholic acid from porcine cholic acid tail residue.
