Description

Technical Field

[0001] This application relates to the field of fecal separation and extraction technology, and more specifically, to a giant panda fecal separation device. Background Technology

[0002] Sampling surveys of endangered species must be conducted with minimal harm to living animals. In recent years, non-invasive sampling methods have been increasingly widely used in genetic research for the conservation of endangered animals. Non-invasive sampling methods involve collecting detached hair, feces, exfoliated cells from the mouth, old skin, etc., as samples for genetic analysis without harming or touching the animal.

[0003] As a Class I protected wild animal in China, the giant panda's genetic analysis and research are crucial for effective conservation efforts. Sampling studies primarily involve obtaining panda feces and extracting and analyzing the mucus within. Typically, fecal separation and extraction are performed using centrifugation, with the addition of ethanol or similar substances to remove impurities. After multiple centrifugations, a sample containing retained genetic material is formed. Currently, most centrifuges operate at a single speed and distribution, requiring multiple separations and manual extractions to obtain a single sample, which is time-consuming and labor-intensive.

[0004] Therefore, designing a giant panda feces separation device that can automatically extract giant panda feces samples in one go while providing multi-speed separation is an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this application is to provide a giant panda feces separation device. This device achieves multi-speed centrifugation by combining a solar centrifuge mechanism, a planetary centrifuge body, a planetary carrier centrifuge mechanism, and an outer ring centrifuge mechanism to form a planetary gear system. Simultaneously, because the entire device can simultaneously centrifuge giant panda feces multiple times, it fully automates the multiple centrifugation and sample extraction, improving the efficiency of giant panda feces separation, saving time, and reducing labor costs. Furthermore, due to the characteristics of the planetary gear system, it can achieve a relatively high output speed even at low output speeds, thus saving energy to a certain extent, making it environmentally friendly and highly efficient.

[0006] In a first aspect, embodiments of this application provide a giant panda feces separation device, including a solar centrifuge mechanism, a planetary centrifuge body, a planetary frame centrifuge mechanism, and an outer ring centrifuge mechanism; the solar centrifuge mechanism, the planetary frame centrifuge mechanism, and the outer ring centrifuge mechanism are coaxially arranged; the solar centrifuge mechanism meshes with the outer ring centrifuge mechanism through the planetary centrifuge body; the planetary frame centrifuge mechanism is connected to the planetary centrifuge body; centrifuge tubes are spaced apart inside the solar centrifuge mechanism; an outer ring centrifuge chamber is opened inside the outer ring centrifuge mechanism; the outer ring centrifuge chamber and the centrifuge tubes are connected through the planetary frame centrifuge mechanism.

[0007] In this embodiment, the device achieves multi-speed centrifugation by combining a solar centrifuge mechanism, a planetary centrifuge body, a planetary carrier centrifuge mechanism, and an outer ring centrifuge mechanism to form a planetary gear system separation device. Simultaneously, because the entire device can centrifuge giant panda feces multiple times, it fully automates the multiple centrifugation extraction of sample liquid, improving the efficiency of giant panda feces separation, saving time, and reducing labor costs. Furthermore, due to the characteristics of the planetary gear system, it can achieve a relatively high output speed even at low output speeds, thus saving energy to a certain extent, making it both environmentally friendly and efficient.

[0008] As one possible implementation, the solar centrifuge mechanism includes a coaxially arranged linkage disk, a solar centrifuge box, and a solar rotation shaft; the solar centrifuge box and the linkage disk are fitted onto the solar rotation shaft; a receiving groove is formed on the linkage disk; the solar centrifuge box is located in the receiving groove; a positioning groove is formed on the bottom surface of the solar centrifuge box on the side corresponding to the linkage disk; a positioning protrusion is formed on the bottom surface of the linkage disk on the side corresponding to the solar centrifuge box; the position of the positioning protrusion is adapted to the position of the positioning groove; the solar rotation shaft is hollow to form a shaft hole; the planetary carrier centrifuge mechanism passes through the shaft hole and connects to the planetary centrifuge body.

[0009] In this embodiment, the solar centrifugal mechanism serves as the sun gear in the planetary gear system. If the solar centrifugal mechanism is used as the output end and its rotational speed is higher than that of the outer ring centrifugal mechanism, it can be used as the subsequent giant panda feces centrifugal separation mechanism, while the outer ring centrifugal mechanism at the input end serves as the initial giant panda feces centrifugal separation mechanism. This way, since the subsequent giant panda feces centrifugal separation requires a higher rotational speed, the rotational speed of the solar centrifugal mechanism can provide a guaranteed speed, ensuring that the giant panda feces centrifugal separation effect meets the requirements of centrifugal separation. Furthermore, the solar centrifugal mechanism is divided into a solar centrifugal housing and a linkage disc, allowing for the replacement of different types of solar centrifugal housings according to the required number of centrifugation cycles, thus meeting the required number of centrifugation cycles per cycle. Simultaneously, it facilitates the removal of the solar centrifugal housing for cleaning and maintenance.

[0010] As one possible implementation, an independent centrifuge cylinder is also included; the independent centrifuge cylinder is sleeved on the solar rotation axis and sandwiched between the solar centrifuge box and the linkage disk; an isolation boss is formed at the end of the solar rotation axis away from the solar centrifuge box; one end of the independent centrifuge cylinder abuts against the isolation boss, and the other end abuts against the solar centrifuge box, so that the solar centrifuge box and the linkage disk are separated.

[0011] In this embodiment, the separation device can not only achieve simultaneous multi-speed centrifugal separation, but also perform supplementary separation of giant panda feces or centrifugal separation of giant panda feces with fewer cycles by operating the solar centrifuge box independently. The solar centrifuge box is supported by an independent centrifuge cylinder, separating it from the linkage turntable, thereby achieving the effect of independently rotating the solar centrifuge box.

[0012] As one possible implementation, an independent protrusion is provided on the side of the independent centrifuge tube that contacts the solar centrifuge box; the position of the independent protrusion is adapted to the position of the positioning groove.

[0013] In this embodiment, by setting an independent protrusion that cooperates with the positioning groove, the stability of the solar centrifuge box can be ensured when the solar centrifuge box is rotated independently, thus ensuring the smooth progress of the centrifugal separation motion.

[0014] As one possible implementation, the solar centrifuge box includes a solar centrifuge box cover and a solar centrifuge platform; the solar centrifuge box cover is fitted onto the solar rotating shaft and covers the solar centrifuge platform; the solar centrifuge box cover is provided with a solar rotating ring; the first conduit of the planetary carrier centrifuge mechanism passes through the solar rotating ring and connects with a liquid collection ring groove opened on the solar centrifuge platform; the solar centrifuge platform is recessed to form a centrifuge chamber; the side wall of the centrifuge chamber is inclined, and fixed centrifuge grooves are spaced apart on the side wall; the centrifuge tube is placed in the fixed centrifuge groove; the liquid collection ring groove is connected to the centrifuge tube through a first drainage pipe; a centrifuge ring groove is also opened on the solar centrifuge platform; the centrifuge ring groove is connected to the centrifuge tube through a second drainage pipe; both the first drainage pipe and the second drainage pipe are provided with check valves.

[0015] In this embodiment, a specific structure of a solar centrifuge chamber is provided. The function of the solar rotating ring is to ensure that the first conduit is not broken due to the speed difference when the rotational speed of the planetary centrifuge mechanism and the rotational speed of the solar centrifuge chamber are different. The solar rotating ring on the solar centrifuge chamber cover can maintain the same rotational speed as the planetary centrifuge mechanism. The inclined sidewall of the centrifuge chamber can ensure that the centrifuge tubes can be stably attached to the fixed centrifuge tank. It can be understood that the liquid collection ring tank is used to temporarily store the clear liquid on the upper layer of giant panda feces introduced after the initial centrifugation separation by the outer ring centrifuge mechanism. Then, according to the set sequence of centrifuge tubes used, the clear liquid of giant panda feces is introduced into the centrifuge tubes through the first drainage tube connected to the corresponding centrifuge tubes for centrifugation separation. It can be understood that the number of centrifugations is consistent with the number of centrifuge tubes that can be placed in the solar centrifuge chamber. Therefore, in order to meet the centrifugation work of giant panda feces separation under different conditions, multiple fixed centrifuge tanks can be opened on the sidewall of the centrifuge chamber, and centrifuge tubes can be placed according to the needs of each centrifugation. Similarly, a first drainage tube is installed at the corresponding fixed centrifuge tank position, and a check valve is installed in the first drainage tube. The check valve of the first drainage tube, where the centrifuge tube used for the first centrifugation is located, is easily opened according to the centrifugation sequence, allowing the clarified panda feces liquid to enter the centrifuge tube for centrifugation. After the first centrifugation, the supernatant liquid of the panda feces in the centrifuge tube needs to be extracted and transferred to the centrifuge tube for the second centrifugation. In this embodiment, a second drainage tube is used to first introduce the supernatant liquid into the centrifuge ring tank. Then, the check valve of the second drainage tube corresponding to the centrifuge tube used for the second centrifugation is opened, allowing the supernatant liquid of the panda feces to be introduced into the centrifuge tube for the second centrifugation. This process can be repeated multiple times as needed. After the final centrifugation, the supernatant liquid is extracted again, and the centrifuge tube is removed to obtain the desired panda feces sample.

[0016] As one possible implementation, the second drainage tube has drainage ports spaced apart on the annular wall located in the centrifuge tube.

[0017] In this embodiment of the application, since it is necessary to extract the upper liquid of giant panda feces, if the drainage is carried out through the opening at the end of the second drainage tube, it may cause the precipitated impurities to be drawn out again. Therefore, by setting a drainage port on the tube wall, it can be ensured that no precipitated impurities are mixed in during extraction.

[0018] As one possible implementation, the planetary carrier centrifuge mechanism includes a planetary carrier rotating shaft, a planetary carrier body, a planetary connecting shaft, a first conduit, and a second conduit. One end of the planetary carrier rotating shaft passes through the solar rotating shaft and is connected to the planetary carrier body. The end of the planetary carrier body away from the planetary carrier rotating shaft is connected to the planetary connecting shaft. The planetary connecting shaft is connected to the planetary centrifuge body. A control air passage is formed along the axis of the planetary carrier rotating shaft. A drainage hole is formed along the axis of the planetary carrier body. The control air passage is connected to the drainage hole. One end of the first conduit is connected to the drainage hole, and the other end passes through the solar rotating ring and is connected to the liquid collection ring groove. One end of the second conduit is connected to the drainage hole, and the other end is connected to the outer ring centrifuge chamber.

[0019] In this embodiment, the more important function of the planetary centrifuge mechanism is to guide the panda feces separation liquid from the outer ring centrifuge mechanism to the solar centrifuge mechanism. This involves guiding the clarified upper layer of panda feces formed during the initial centrifugation in the outer ring centrifuge mechanism to the solar centrifuge mechanism for subsequent high-speed centrifugation. To automate the liquid flow, a control air channel connected to the liquid flow orifice is provided. This control air channel uses either negative pressure created by drawing in gas or pressurization to create a pushing pressure, thereby achieving full automation of liquid flow and improving the efficiency of centrifugal separation.

[0020] As one possible implementation, an airway shut-off valve is installed on the control airway; a drainage shut-off valve is installed in the drainage hole at the position between the first and second guide tubes.

[0021] In this embodiment, a shut-off valve is installed on the air passage to control the opening and closing of the induced air; the drainage shut-off valve is used to control the introduction and discharge of liquid. When liquid needs to be introduced into the outer ring centrifuge mechanism, the air passage shut-off valve can be opened first, and the drainage shut-off valve and the check valve on the first drainage pipe on the liquid collection ring groove can be closed. By extracting gas from the liquid collection ring groove, a negative pressure is formed in the liquid collection ring groove. At this time, the air passage shut-off valve is closed, and the drainage shut-off valve is opened. Under the action of pressure, the liquid of the outer ring centrifuge mechanism is automatically introduced into the liquid collection ring groove. Then, the drainage shut-off valve is closed again, the check valve on the first drainage pipe corresponding to the centrifuge tube required for the first centrifugation is opened, and the air passage shut-off valve is opened at the same time. The liquid is introduced into the centrifuge tube for centrifugal separation by blowing air.

[0022] As one possible implementation, the outer ring centrifuge mechanism includes an outer ring centrifuge disc and an outer ring centrifuge cover; the outer ring centrifuge disc is hollow to form an outer ring centrifuge cavity; the outer ring centrifuge cover is placed on the outer ring centrifuge disc to seal the outer ring centrifuge cavity; an outer ring rotating ring is provided on the outer ring centrifuge cover; a second conduit passes through the outer ring rotating ring and connects to the outer ring centrifuge cavity.

[0023] In this embodiment, the outer ring centrifuge chamber of the outer ring centrifuge mechanism is a large centrifuge chamber. Since the initial centrifugation may involve a large quantity and variety of panda fecal samples, this provides ample space for centrifugation. Of course, considering multiple extractions at once, the outer ring centrifuge chamber can be divided into sections, which can also improve the efficiency of the centrifugation process to some extent.

[0024] As one possible implementation, the second conduit has flow guide ports spaced apart on the ring wall located in the outer ring centrifuge chamber.

[0025] In this embodiment of the application, considering that preliminary centrifugation requires the extraction of the clarified liquid from the upper layer of giant panda feces, in order to avoid the mixing of sediment impurities during extraction, a guide port is opened on the tube wall to ensure the purity of the extraction.

[0026] The beneficial effects of the giant panda feces separation device provided in this embodiment are as follows:

[0027] A planetary gear system separation device is constructed by combining a solar centrifuge mechanism, a planetary centrifuge body, a planetary carrier centrifuge mechanism, and an outer ring centrifuge mechanism to achieve multi-speed centrifugation. Simultaneously, because the entire device can centrifuge giant panda feces multiple times, it fully automates the multiple centrifugation extraction of sample liquid, improving the efficiency of giant panda feces separation, saving time, and reducing labor costs. Furthermore, due to the characteristics of the planetary gear system, it can achieve a relatively high output speed mode even at low output speeds, thus saving energy to a certain extent, making it both environmentally friendly and highly efficient.

Detailed Implementation

[0035] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0036] Sampling surveys of endangered species must be conducted with minimal harm to living animals. In recent years, non-invasive sampling methods have been increasingly widely used in genetic research for the conservation of endangered animals. Non-invasive sampling methods involve collecting detached hair, feces, exfoliated cells from the mouth, old skin, etc., as samples for genetic analysis without harming or touching the animal.

[0037] As a Class I protected wild animal in China, the giant panda's genetic analysis and research are crucial for effective conservation efforts. Sampling studies primarily involve obtaining panda feces and extracting and analyzing the mucus within. Typically, fecal separation and extraction are performed using centrifugation, with the addition of ethanol or similar substances to remove impurities. After multiple centrifugations, a sample containing retained genetic material is formed. Currently, most centrifuges operate at a single speed and distribution, requiring multiple separations and manual extractions to obtain a single sample, which is time-consuming and labor-intensive.

[0038] refer to Figures 1-4This application provides a giant panda feces separation device. The device includes a solar centrifuge mechanism 01, a planetary centrifuge body 02, a planetary frame centrifuge mechanism 03, and an outer ring centrifuge mechanism 04; the solar centrifuge mechanism 01, the planetary frame centrifuge mechanism 03, and the outer ring centrifuge mechanism 04 are coaxially arranged; the solar centrifuge mechanism 01 engages with the outer ring centrifuge mechanism 04 via the planetary centrifuge body 02; the planetary frame centrifuge mechanism 03 is connected to the planetary centrifuge body 02; centrifuge tubes 05 are spaced apart within the solar centrifuge mechanism 01; an outer ring centrifuge chamber is formed within the outer ring centrifuge mechanism 04; the outer ring centrifuge chamber and the centrifuge tubes 05 are connected via the planetary frame centrifuge mechanism 03.

[0039] This device achieves multi-speed centrifugation by combining a solar centrifuge mechanism 01, a planetary centrifuge body 02, a planetary carrier centrifuge mechanism 03, and an outer ring centrifuge mechanism 04 into a planetary gear system. Simultaneously, because the entire device can centrifuge giant panda feces multiple times, it fully automates the multiple centrifugation extraction of sample liquid, improving the efficiency of giant panda feces separation, saving time, and reducing labor costs. Furthermore, due to the characteristics of the planetary gear system, it can achieve a relatively high output speed even at low output speeds, thus saving energy to a certain extent, making it both environmentally friendly and highly efficient.

[0040] Specifically, the solar centrifuge mechanism 01 includes a coaxially arranged linkage disk 11, a solar centrifuge box 12, and a solar rotation shaft 13; the solar centrifuge box 12 and the linkage disk 11 are sleeved on the solar rotation shaft 13; a receiving groove is provided on the linkage disk 11; the solar centrifuge box 12 is located in the receiving groove; a positioning groove 1226 is provided on the bottom surface of the solar centrifuge box 12 corresponding to the side of the linkage disk 11; a positioning protrusion 111 is provided on the bottom surface of the linkage disk 11 corresponding to the side of the solar centrifuge box 12; the position of the positioning protrusion 111 is adapted to the position of the positioning groove 1226; the solar rotation shaft 13 is hollow to form a shaft hole; the planetary carrier centrifuge mechanism 03 passes through the shaft hole and is connected to the planetary centrifuge body 02.

[0041] The solar centrifuge mechanism 01, acting as the sun gear in the planetary gear system, is used as the output end and its rotational speed must be higher than that of the outer ring centrifuge mechanism 04. Therefore, the solar centrifuge mechanism 01 can serve as the subsequent giant panda feces centrifuge separation mechanism, while the outer ring centrifuge mechanism 04 at the input end serves as the initial giant panda feces centrifuge separation mechanism. This ensures that the subsequent giant panda feces centrifuge separation requires a higher rotational speed, and the rotational speed of the solar centrifuge mechanism 01 provides sufficient speed to meet the centrifugation requirements. Furthermore, the solar centrifuge mechanism 01 is divided into a solar centrifuge housing 12 and a linkage disc 11. Different types of solar centrifuge housing 12 can be replaced according to the required number of centrifugation cycles to achieve the required number of cycles per cycle. This also facilitates the removal of the solar centrifuge housing 12 for cleaning and maintenance.

[0042] In addition, it also includes an independent centrifuge tube 14; the independent centrifuge tube 14 is sleeved on the solar rotation shaft 13 and sandwiched between the solar centrifuge box 12 and the linkage disk 11; an isolation boss is formed at the end of the solar rotation shaft 13 away from the solar centrifuge box 12; one end of the independent centrifuge tube 14 abuts against the isolation boss, and the other end abuts against the solar centrifuge box 12, so that the solar centrifuge box 12 is separated from the linkage disk 11.

[0043] This separation device can not only achieve simultaneous multi-speed centrifugal separation, but also perform supplementary separation of giant panda feces or centrifugal separation of giant panda feces with fewer cycles by operating the solar centrifuge box 12 independently. The solar centrifuge box 12 is supported by an independent centrifuge cylinder 14, which separates the solar centrifuge box 12 from the linkage turntable, thereby achieving the effect of independently rotating the solar centrifuge box 12.

[0044] It is understood that an independent protrusion 141 is provided on the side of the independent centrifuge tube 14 that contacts the solar centrifuge box 12; the position of the independent protrusion 141 is adapted to the position of the positioning groove 1226. By setting the independent protrusion 141 to cooperate with the positioning groove 1226, the stability of the solar centrifuge box 12 can be ensured when the solar centrifuge box 12 is rotated independently, and the centrifugal separation movement can be guaranteed.

[0045] The solar centrifuge box 12 includes a solar centrifuge box cover 121 and a solar centrifuge platform 122. The solar centrifuge box cover 121 is sleeved on the solar rotating shaft 13 and covers the solar centrifuge platform 122. The solar centrifuge box cover 121 is provided with a solar rotating ring 1211. The first conduit 34 of the planetary frame centrifuge mechanism 03 passes through the solar rotating ring 1211 and connects with the liquid collection ring groove 1222 opened on the solar centrifuge platform 122. The solar centrifuge platform 122 is concave to form a centrifuge. The centrifuge chamber has an inclined side wall, and fixed centrifuge grooves 1221 are spaced apart on the side wall; centrifuge tubes 05 are disposed in the fixed centrifuge grooves 1221; the liquid collection ring groove 1222 is connected to the centrifuge tubes 05 through the first drainage pipe 1224; a centrifuge ring groove 1223 is also provided on the solar centrifuge platform 122; the centrifuge ring groove 1223 is connected to the centrifuge tubes 05 through the second drainage pipe 1225; both the first drainage pipe 1224 and the second drainage pipe 1225 are provided with check valves 1227.

[0046] The function of the solar rotating ring 1211 is to ensure that the first conduit 34 is not broken due to the speed difference when the rotational speed of the planetary centrifuge mechanism 03 and the solar centrifuge box 12 are different. The solar rotating ring 1211 on the solar centrifuge box cover 121 can maintain the same rotational speed as the planetary centrifuge mechanism 03. The inclined side wall of the centrifuge chamber can ensure that the centrifuge tube 05 can be stably attached to the fixed centrifuge tank 1221. It can be understood that the liquid collection ring tank 1222 is used to temporarily store the clear liquid on the upper layer of giant panda feces introduced after the initial centrifugation separation of the outer ring centrifuge mechanism 04. Then, according to the set sequence of centrifuge tubes 05, the clear liquid of giant panda feces is introduced into the centrifuge tubes 05 for centrifugation separation using the first drainage tube 1224 connected to the corresponding centrifuge tubes 05. It can be understood that the number of centrifugations is consistent with the number of centrifuge tubes 05 that can be placed in the solar centrifuge box 12. Therefore, to meet the requirements of giant panda feces separation and centrifugation under different conditions, multiple fixed centrifuge tanks 1221 can be opened on the side wall of the centrifuge chamber, and centrifuge tubes 05 can be placed according to the number of centrifugations required each time. Similarly, a first drainage pipe 1224 is set at the corresponding fixed centrifuge tank 1221 position, and a check valve 1227 is set in the first drainage pipe 1224. According to the centrifugation separation sequence set by the centrifuge tubes 05, it is convenient to open the check valve 1227 of the first drainage pipe 1224 where the centrifuge tube 05 used for the first centrifugation is located, so that the clarified liquid of giant panda feces enters the centrifuge tube 05 for centrifugation separation. After the first centrifugation separation, it is necessary to extract the upper liquid of giant panda feces in the centrifuge tube 05 and enter it into the centrifuge tube 05 for the second centrifugation separation. In this embodiment, the second drainage pipe 1225 is used to first introduce the upper liquid of giant panda feces into the centrifuge ring tank 1223. After opening the check valve 1227 of the second drainage pipe 1225 corresponding to the centrifuge tube 05 used for the second centrifugation separation, the upper liquid is introduced into the centrifuge tube 05 for the second centrifugation separation. This process can be repeated multiple times as needed. After the final centrifugation, the supernatant liquid is extracted once more, and centrifuge tube 05 is then removed to obtain the desired giant panda fecal sample.

[0047] It is understandable that liquid transfer between centrifuge tubes 05 can be controlled by installing bypass pipelines for suction and exhaust on the centrifuge annular tank 1223, and by installing bypass valves. When liquid needs to be transferred, first close the check valves 1227 on all second drainage pipes 1225, open the bypass valve to create negative pressure by suction, then close the bypass valve and open the check valve 1227 on the second drainage pipe 1225 corresponding to the centrifuge tube 05 from which liquid needs to be extracted. Under negative pressure, the liquid is guided to the centrifuge annular tank 1223. Then close the check valve 1227 and open the check valve 1227 on the second drainage pipe 1225 corresponding to the centrifuge tube 05 to which liquid needs to be introduced. Finally, air is blown through the bypass valve to introduce the liquid into the centrifuge tube 05. Of course, the bypass valve can also be used as a cleaning pipeline to clean the centrifuge annular tank 1223 after each liquid transfer.

[0048] It should be noted that the second drainage tube 1225 has drainage ports 1228 spaced apart on the annular wall inside the centrifuge tube 05. Since it is necessary to extract the upper liquid of giant panda feces, if the drainage is performed through the opening at the end of the second drainage tube 1225, it may cause the precipitated impurities to be drawn out again. Therefore, by setting drainage ports 1228 on the tube wall, it can be ensured that no precipitated impurities are mixed in during extraction.

[0049] The planetary carrier centrifuge mechanism includes a planetary carrier rotating shaft 31, a planetary carrier body 32, a planetary connecting shaft 33, a first conduit 34, and a second conduit 35. One end of the planetary carrier rotating shaft 31 passes through the sun rotating shaft 13 and is connected to the planetary carrier body 32. The end of the planetary carrier body 32 away from the planetary carrier rotating shaft 31 is connected to the planetary connecting shaft 33. The planetary connecting shaft 33 is connected to the planetary centrifuge body 02. The planetary carrier rotating shaft 31 has a control air passage 311 along its axis. The planetary carrier body 32 has a drainage hole 321 along its axis. The control air passage 311 is connected to the drainage hole 321. One end of the first conduit 34 is connected to the drainage hole 321, and the other end passes through the sun rotating ring 1211 and is connected to the liquid collection ring groove 1222. One end of the second conduit 35 is connected to the drainage hole 321, and the other end is connected to the outer ring centrifuge chamber.

[0050] The more important function of the planetary centrifuge mechanism is to guide the panda feces separation liquid from the outer ring centrifuge mechanism 04 to the solar centrifuge mechanism 01. This involves guiding the clarified upper layer of panda feces formed during the initial centrifugation in the outer ring centrifuge mechanism 04 to the solar centrifuge mechanism 01 for subsequent high-speed centrifugation. To automate the liquid flow, a control air passage 311 connected to the liquid flow drainage hole 321 is provided. The control air passage 311 uses either negative pressure created by drawing in gas or pressure to create a pushing pressure to achieve liquid extraction and discharge, fully automating the liquid flow and improving the efficiency of centrifugal separation.

[0051] It should be noted that an airway shut-off valve is installed on the control airway 311; a drainage shut-off valve is installed in the drainage hole 321 between the first conduit 34 and the second conduit 35. The shut-off valve on the airway is used to control the opening and closing of the induced air; the drainage shut-off valve is used to control the introduction and discharge of liquid. When it is necessary to introduce liquid from the outer ring centrifugal mechanism 04, the airway shut-off valve can be opened first, and the drainage shut-off valve and the check valve 1227 on the first drainage pipe 1224 on the liquid collection ring groove 1222 can be closed. By extracting the gas in the liquid collection ring groove 1222, a negative pressure is formed in the liquid collection ring groove 1222. At this time, the airway shut-off valve is closed and the drainage shut-off valve is opened. Under the action of pressure, the liquid of the outer ring centrifugal mechanism 04 is automatically introduced into the liquid collection ring groove 1222. At this point, close the drainage stop valve, open the stop valve 1227 on the first drainage tube 1224 corresponding to the centrifuge tube 05 required for the first centrifugation, and at the same time open the airway stop valve to introduce the liquid into the centrifuge tube 05 for centrifugation separation by blowing air.

[0052] The outer ring centrifuge mechanism 04 includes an outer ring centrifuge disc 41 and an outer ring centrifuge cover 42; the outer ring centrifuge disc 41 is hollow to form an outer ring centrifuge cavity; the outer ring centrifuge cover 42 covers the outer ring centrifuge disc 41 and seals the outer ring centrifuge cavity; an outer ring rotating ring 421 is provided on the outer ring centrifuge cover 42; the second conduit 35 passes through the outer ring rotating ring 421 and communicates with the outer ring centrifuge cavity.

[0053] The outer ring centrifuge chamber of the outer ring centrifuge mechanism 04 is a large centrifuge chamber, which provides ample space for centrifugation, especially considering the potentially large and varied sample size of panda feces during initial centrifugation. Of course, to accommodate multiple extractions at once, the outer ring centrifuge chamber can be divided into sections, which can also improve the efficiency of the centrifugation process to some extent.

[0054] Of course, the second conduit 35 has flow guides spaced apart on the ring wall located in the outer ring centrifuge chamber. Considering that the preliminary centrifugation separation requires the extraction of the clarified liquid from the upper layer of giant panda feces, flow guides are provided on the tube wall to ensure the purity of the extraction in order to avoid the mixing of sediment impurities during extraction.

[0055] In summary, the beneficial effects of the giant panda feces separation device provided in this application embodiment are as follows:

[0056] A planetary gear system separation device is formed by combining the solar centrifuge mechanism 01, the planetary centrifuge body 02, the planetary carrier centrifuge mechanism 03, and the outer ring centrifuge mechanism 04 to achieve multi-speed centrifugation. Simultaneously, because the entire device can centrifuge giant panda feces multiple times, it fully automates the multiple centrifugation extraction of sample liquid, improving the efficiency of giant panda feces separation, saving time, and reducing labor costs. Furthermore, due to the characteristics of the planetary gear system, it can achieve a relatively high output speed mode even at low output speeds, which can save energy to a certain extent, making it both environmentally friendly and highly efficient.

[0057] In this application, "at least one" means one or more, and "more than one" means two or more.
