Description

Technical Field

[0001] Embodiments of this application relate to the field of separating particles from liquids or separating liquids from solids, and more specifically to a solid-liquid separation apparatus that facilitates the removal of solid materials. Background Technology

[0002] The statements herein are provided merely as background information in connection with this application and do not necessarily constitute prior art.

[0003] When separating liquids containing solid powder, centrifugation is typically required because the powder is suspended in the liquid. However, after centrifugation, the powder adheres to the inner wall of the centrifuge container, making it difficult to remove. This is especially true when the powder is radioactive; the radioactivity further complicates the process, making it even more difficult to separate the radioactive powder from the centrifuge container manually or using a robotic arm. Summary of the Invention

[0004] A brief overview of this application is provided below to offer a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the application. It is not intended to identify key or essential parts of the application, nor is it intended to limit its scope. Its purpose is merely to present certain concepts in a simplified form as a prelude to the more detailed description that follows.

[0005] To address the aforementioned problems, embodiments of this application provide a solid-liquid separation device for easy removal of solid materials, comprising a centrifugal assembly, an inlet / outlet liquid assembly, a collection component, and a drive assembly. The centrifugal assembly separates a solid-liquid mixture into liquid and solid materials; the inlet / outlet liquid assembly allows the solid-liquid mixture to enter the centrifugal assembly and the separated liquid to exit the centrifugal assembly; the collection component collects the separated solid material; and the drive assembly drives the centrifugal assembly to rotate relative to the inlet / outlet liquid assembly, thereby separating the solid-liquid mixture. The centrifugal assembly and the drive assembly are configured to drive the separated solid material into the collection component.

[0006] The solid-liquid separation device provided in the embodiments of this application, by configuring the centrifugal component and the driving component to drive the separated solid material into the collecting component, can avoid the solid material remaining inside the centrifugal component, thus avoiding affecting the subsequent centrifugation effect, and facilitates the removal of the separated solid material from the device.

[0043] Exemplary embodiments of this application will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the content of this application.

[0044] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0045] See Figure 1 and Figure 2This application provides a solid-liquid separation device 100, which may include a centrifugal assembly 10, an inlet / outlet liquid assembly 20, a collection component 30, and a drive assembly 40. The centrifugal assembly 10 separates a solid-liquid mixture into liquid and solid materials; the inlet / outlet liquid assembly 20 allows the solid-liquid mixture to enter the centrifugal assembly 10 and the separated liquid to flow out of the centrifugal assembly 10; the collection component 30 collects the separated solid material; and the drive assembly 40 drives the centrifugal assembly 10 to rotate relative to the inlet / outlet liquid assembly 20, thereby separating the solid-liquid mixture. The centrifugal assembly 10 and the drive assembly 40 are configured to drive the separated solid material into the collection component 30.

[0046] The solid-liquid separation device 100 provided in the embodiments of this application, by setting the centrifugal assembly 10 and the driving assembly 40 to drive the separated solid material into the collection member 30, can avoid the solid material remaining inside the centrifugal assembly 10, avoid affecting the subsequent centrifugation effect, and facilitate the removal of the separated solid material from the solid-liquid separation device 100.

[0047] In some embodiments, the solid material may be a radioactive powder, and the separated liquid may also be radioactive.

[0048] See Figures 2 to 6 In some embodiments, the centrifugal assembly 10 may include a centrifugal housing 11, a centrifugal body 12, a movable component 13, and a pressure regulating component 14. The centrifugal housing 11 is configured to form a centrifugal cavity 1101, and a plurality of solid material outlets 1102 are provided circumferentially on the radially outer side of the centrifugal housing 11 for allowing solid materials in the centrifugal cavity 1101 to enter the collection component 30; the centrifugal body 12 is disposed in the centrifugal cavity 1101 and is used to rotate together with the centrifugal housing 11 to separate the solid-liquid mixture; the movable component 13 is movably disposed in the centrifugal cavity 1101; and the pressure regulating component 14 is disposed in the centrifugal housing 11.

[0049] See Figure 2 , Figure 4 and Figure 6In some embodiments, the drive assembly 40 is further configured to cooperate with the pressure regulating member 14 to change the pressure on one side of the movable member 13, so that the movable member 13 can move between a first position with the multiple solid material outlets 1102 open and a second position with the multiple solid material outlets 1102 closed. When the movable member 13 opens the multiple solid material outlets 1102, the solid material separated in the centrifuge chamber 1101 can enter the collection member 30 through the multiple solid material outlets 1102 under centrifugal action. In the embodiments of this application, the drive assembly 40 cooperates with the pressure regulating member 14 to change the pressure on one side of the movable member 13, so that the movable member 13 can move between a first position with the multiple solid material outlets 1102 open and a second position with the multiple solid material outlets 1102 closed, thereby enabling the solid material outlets 1102 to be opened or closed, facilitating the timely delivery of the separated solid material into the collection member 30.

[0050] In some embodiments, the movable member 13 and the centrifuge housing 11 can form a sealed cavity 16, and the pressure regulating member 14 can be used to regulate the pressure inside the sealed cavity 16. By regulating the pressure inside the sealed cavity 16, the movable member 13 can move between a first position and a second position, thereby enabling the solid material outlet 1102 to be opened or closed, facilitating the timely delivery of the separated solid material into the collection member 30.

[0051] See Figure 2 , Figure 4 or Figure 6 In some embodiments, the pressure regulating member 14 may include a first inlet channel 141, an outlet channel 142, a valve 143, and a second inlet channel 144. The first inlet channel 141 is formed in the centrifuge housing 11 for supplying fluid to the sealed cavity 16; the outlet channel 142 is formed in the centrifuge housing 11 for allowing fluid in the sealed cavity 16 to flow out; the valve 143 is used to close or open the outlet channel 142; the second inlet channel 144 is formed in the centrifuge housing 11 for supplying fluid to apply pressure to the valve 143, so that the valve 143 opens the outlet channel 142, thereby allowing fluid in the sealed cavity 16 to flow out through the outlet channel 142, thereby enabling the movable member 13 to move from a second position that closes the plurality of solid material outlets 1102 to a first position that opens the plurality of solid material outlets 1102.

[0052] In some embodiments, the centrifuge housing 11 forms a channel, one end of which penetrates the centrifuge housing 11 and the other end of which is in fluid communication with the liquid outlet channel 142. A valve 143 is disposed within this channel. The valve 143 includes a valve body 1431, a valve switch 1432, and a reset member. The valve body 1431 is fixedly disposed within the channel, forming a valve passage 14311 that connects the liquid outlet channel 142 to the receiving cavity 53. The valve switch 1432 is movably disposed within the channel, and the reset member provides a force to the valve switch 1432 to move the valve body 1431, thereby closing the valve passage 14311 of the valve body 1431 and disconnecting the passage between the valve passage 14311 and the liquid outlet channel 142. When the fluid enters the second inlet channel 144, under the action of fluid pressure, the valve switch 1432 moves away from the valve body 1431, thereby connecting the valve channel 14311 with the outlet channel 142. At this time, the fluid in the sealing cavity 16 can enter the valve channel 14311 through the outlet channel 142 and flow to the outside of the centrifuge housing 11 (for example, flow into the receiving cavity 53 formed by the outer shell 50 mentioned below).

[0053] See Figure 6 and Figure 7 In some embodiments, the drive assembly 40 may include a drive shaft 41 connected to the centrifuge housing 11, thereby driving the centrifuge housing 11 to rotate. In some embodiments, a first liquid inlet mating channel 411 and a second liquid inlet mating channel 412 are formed on the drive shaft 41, respectively for supplying fluid to the first liquid inlet channel 141 and the second liquid inlet channel 144. The solid-liquid separation device 100 provided in the embodiments of this application, by setting the liquid inlet mating channel on the drive shaft 41, can realize the supply of fluid to the liquid inlet channel formed in the centrifuge housing 11, thereby changing the pressure in the sealed cavity 16, and realizing the movement of the drive movable member 13 between a first position with the multiple solid material outlets 1102 open and a second position with the multiple solid material outlets 1102 closed.

[0054] See Figure 6 and Figure 7 In some embodiments, the drive shaft 41 may form a first annular groove 4001, a second annular groove 4002 and a third annular groove 4003, the three annular grooves being spaced apart along the axial direction. The first annular groove 4001 and the second annular groove 4002 are respectively connected to an external fluid source through a rotary joint, and the third annular groove 4003 is in fluid communication with a plurality of second liquid inlet channels 144.

[0055] See Figure 6 and Figure 7In some embodiments, the drive shaft 41 also forms a first channel 401 and a second channel 402 extending axially. The first channel 401 is in fluid communication with the second annular groove 4002 and with the first inlet channel 141, so as to supply fluid to the first inlet channel 141 through the second annular groove 4002, thereby increasing the fluid volume and pressure within the sealed cavity 16. The second channel 402 connects the first annular groove 4001 and the third annular groove 4003, so as to supply fluid to the second inlet channel 144 through the first annular groove 4001. The fluid may be, for example, water.

[0056] See Figure 6 In some embodiments, the first liquid inlet channel 411 may include a first channel 401 and a second annular groove 4002, and the second liquid inlet channel 412 may include a first annular groove 4001, a second channel 402 and a third annular groove 4003.

[0057] See Figure 6 and Figure 8 In some embodiments, the centrifuge body 12 may include a plurality of centrifuge units 121 stacked along the axial direction, each centrifuge unit 121 being used to separate a solid-liquid mixture by rotation. The plurality of centrifuge units 121 are configured such that the solid-liquid mixture can be diverted to the plurality of centrifuge units 121 for simultaneous separation by the plurality of centrifuge units 121. The embodiments of this application, by providing a plurality of centrifuge units 121, enable the simultaneous separation of solid-liquid mixtures using the plurality of centrifuge units 121, which is beneficial for improving separation efficiency.

[0058] In some embodiments, the centrifuge unit 121 is configured such that when it rotates, the liquid material in the solid-liquid mixture moves upward along the centrifuge unit 121, and the solid material in the solid-liquid mixture moves downward along the centrifuge unit 121, thereby facilitating the separation of the solid material and the liquid from the centrifuge chamber 1101.

[0059] In some embodiments, see Figure 8 The centrifuge housing 11 forms a feed chamber 1103 located radially inside the centrifuge chamber 1101, allowing solid-liquid mixtures from the inlet / outlet liquid assembly 20 to enter the feed chamber 1103. Multiple feed holes 11111 are circumferentially arranged along the radially inner side of the centrifuge housing 11, communicating with the feed chamber 1103. Solid-liquid mixtures entering the feed chamber 1103 can enter the centrifuge chamber 1101 through the multiple feed holes 11111 under the action of centrifugal force.

[0060] See Figure 2 , Figure 4 or Figure 6In some embodiments, the centrifuge housing 11 may include: a first housing segment 111 that cooperates with the inlet / outlet liquid assembly 20, a second housing segment 112 that is connected to the drive assembly 40, and a third housing segment 113 that connects the first housing segment 111 and the second housing segment 112. The first housing segment 111, the second housing segment 112, and the third housing segment 113 together form an annular centrifuge chamber 1101, and the pressure regulating member 14 is disposed in the second housing segment 112.

[0061] In some embodiments, the first shell section 111 forms a feed chamber 1103, and a feed hole 11111 is formed in the first shell section 111.

[0062] See Figure 6 and Figure 9 In some embodiments, the first shell section 111 may include: a first tube 1111 and a first cover 1112 that closes one end of the first tube 1111. A feed inlet 11111 is formed on the side of the first tube 1111 adjacent to the first cover 1112; the solid-liquid mixture enters the first tube 1111 via the inlet / outlet assembly 20 and then enters the centrifuge chamber 1101 via the feed inlet 11111. The first tube 1111 and the first cover 1112 form the feed chamber 1103. In such embodiments, when the centrifuge assembly 10 rotates, the solid-liquid mixture, after entering the first tube 1111 via the inlet / outlet assembly 20, can directly enter the centrifuge chamber 1101 through the feed inlet 11111 under centrifugal force for separation, which is beneficial for improving feeding efficiency and separation efficiency.

[0063] See Figure 6 and Figure 9 In some embodiments, the first shell section 111 may further include: a second cover 1113 extending radially outward from the other end of the first tube 1111, and an extension 1115 extending from the second cover 1113 in a direction away from the first cover 1112. The extension 1115 and the second cover 1113 together form a liquid storage chamber 24. In such an embodiment, when the centrifugal assembly 10 rotates, the liquid that has separated from the solid powder under the action of centrifugal force can directly enter the liquid storage chamber 24 under the action of centrifugal force to separate from the solid material without the need for other additional operations.

[0064] See Figure 10In some embodiments, the second cover 1113 is provided with an outlet hole 11131 for the liquid in the centrifuge chamber 1101 to enter the liquid storage chamber 24 under centrifugal force; the inlet / outlet assembly 20 is configured to draw out the liquid in the liquid storage chamber 24. The solid-liquid separation device 100 provided in the embodiments of this application forms a liquid storage chamber 24 by making the first shell section 111 form a liquid storage chamber 24 and providing an outlet hole 11131 connecting the centrifuge chamber 1101 and the liquid storage chamber 24, so that the liquid separated by centrifugation can enter the liquid storage chamber 24 and be drawn out by the inlet / outlet assembly 20. The embodiments of this application can avoid a large amount of liquid remaining inside the centrifuge chamber 1101, affecting the continuous separation of materials in the centrifuge chamber 1101, and facilitate the removal of the separated liquid from the solid-liquid separation device 100.

[0065] In some embodiments, the extension 1115 may include a cylindrical section 11151 and a third cover 11152 that extends radially inward from the cylindrical section 11151 toward a direction away from the second cover 1113.

[0066] See Figure 6 and Figure 9 In some embodiments, the first shell segment 111 may further include an inclined portion 1114 extending radially outward and downward from the second cover 1113 to meet the third shell segment 113, the inclined portion 1114 facing the centrifugal unit 121.

[0067] See Figure 5 , Figure 6 and Figure 16 The collecting element 30 is disposed radially outside the second shell section 112, which has multiple solid material outlets 1102 arranged circumferentially for allowing solid material in the centrifugal chamber 1101 to enter the collecting element 30. The solid-liquid separation device 100 provided in the embodiments of this application has multiple solid material outlets 1102 in the second shell section 112, and the collecting element 30 is disposed radially outside the second shell section 112, so that solid material can enter the collecting element 30 through the solid material outlets 1102 under centrifugal force. This improves the efficiency of solid material entering the collecting element 30 from the centrifugal chamber 1101, thereby improving the separation efficiency.

[0068] See Figure 7 In some embodiments, the second shell section 112 may have a receiving hole, and the valve 143 may be disposed in the receiving hole. See also Figure 2 , Figure 4 or Figure 6 In some embodiments, the first liquid inlet channel 141, the second liquid inlet channel 144, and the liquid outlet channel 142 can all be formed in the second shell section 112.

[0069] See Figure 6 and Figure 8In some embodiments, the centrifuge body 12 may further include a first mounting member 122 and a second mounting member 123. The first mounting member 122 is sleeved on the first pipe 1111, and a plurality of centrifuge units 121 are sleeved on the first mounting member 122; the second mounting member 123 is connected to the end of the first mounting member 122 away from the second cover 1113 and is connected to the second shell section 112, and the plurality of centrifuge units 121 are stacked on the second mounting member 123; the solid-liquid mixture entering the centrifuge chamber 1101 through the feed hole 11111 flows through the second mounting member 123 and is diverted to the plurality of centrifuge units 121. By configuring the centrifuge body 12 with the above structure, it is beneficial for the solid-liquid mixture entering through the feed hole 11111 to be diverted to each centrifuge unit 121, thereby improving the separation efficiency of the centrifuge unit 121.

[0070] In some embodiments, all centrifuge units 121 are clamped by the inclined portion 1114 and the second mounting member 123 to achieve positioning of the centrifuge units 121. See also Figure 2 , Figure 4 or Figure 6 In some embodiments, the drive shaft 41 may be connected to the second mounting member 123. In some embodiments, the first tube 1111 is coaxial with the drive shaft 41.

[0071] See Figure 11 In some embodiments, the first mounting member 122 is provided with a positioning part 1221, and the centrifugal unit 121 is provided with a positioning mating part 1211. Through the cooperation of the positioning part 1221 and the positioning mating part 1211, the first mounting member 122 and the centrifugal unit 121 are circumferentially stationary, allowing the centrifugal unit 121 and the first mounting member 122 to rotate together. The first mounting member 122 can be connected to the second mounting member 123 by fasteners, so that when the drive shaft 41 drives the second mounting member 123 to rotate, it can also drive the first mounting member 122 and the centrifugal unit 121 to rotate together.

[0072] In some embodiments, the positioning part 1221 may be a protrusion, and the positioning mating part 1211 may be a groove.

[0073] See Figure 8 In some embodiments, an annular cavity 15 is formed between the first mounting member 122 and the first pipe member 1111, and the annular cavity 15 communicates with the feed port 11111. The solid-liquid mixture can enter the annular cavity 15 through the feed port 11111.

[0074] See Figure 12 In some embodiments, the second mounting member 123 is provided with a plurality of troughs 1231 distributed circumferentially. The troughs 1231 are in communication with the annular cavity 15. The solid-liquid mixture can enter the troughs 1231 through the annular cavity 15 and thus enter the centrifuge cavity 1101.

[0075] See Figure 6 and Figure 10 In some embodiments, a recess 11112 is formed on the side of the first pipe fitting 1111 facing the first cover 1112, and a feed hole 11111 is formed in the recess 11112. An annular cavity 15 is formed between the recess 11112 and the first mounting member 122. The outer diameter of the recess 11112 is smaller than the outer diameter of other parts of the first pipe fitting 1111. The first cover 1112 is in contact with the recess 11112, and the recess 11112 abuts against the second mounting member 123. The first cover 1112 is embedded in the second mounting member 123 and is sealed to the second mounting member 123.

[0076] See Figure 13 In some embodiments, the second mounting member 123 may include a tapered guide section 1232, a connecting section 1234 located radially inward, and an annular section 1233 connecting the guide section 1232 and the connecting section 1234. The connecting section 1234 is located outside the centrifuge chamber 1101 and is connected to the drive shaft 41. In some embodiments, the feed trough 1231 extends from the annular section 1233 to penetrate the guide section 1232.

[0077] The connecting segment 1234 forms a groove with an opening at the top, into which the first cover 1112 is embedded. The first cover 1112 and the connecting segment 1234 are sealed together by a sealing ring to prevent liquid from entering below the groove.

[0078] See Figures 14 to 17 In some embodiments, each centrifugal unit 121 is provided with a plurality of through holes 1212, each through hole 1212 being located between two material tanks 1231, so that the solid-liquid mixture in the material tank 1231 can flow to each centrifugal unit 121 through the through holes 1212 under the action of centrifugal force; which is beneficial to improving the separation efficiency of the centrifugal unit 121.

[0079] In some embodiments, the number of centrifugal units 121 may be more than 10. In some embodiments, the gap between two adjacent centrifugal units 121 is 1-2 mm, so as to facilitate the flow of the solid-liquid mixture entering the material tank 1231 through the through hole 1212 of each centrifugal unit 121 under the action of centrifugal force.

[0080] See Figure 14 In some embodiments, the centrifuge unit 121 may include a centrifuge body 1213 and a plurality of flow guides 1214 formed on the centrifuge body 1213, the surfaces of the flow guides 1214 protruding from the surface of the centrifuge body 1213. See also Figure 14In some embodiments, the solid-liquid mixture can flow through the centrifuge body 1213, with each through hole 1212 located on the centrifuge body 1213 between two adjacent guide members 1214, so that the solid-liquid mixture flowing through the centrifuge body 1213 can rotate synchronously with the centrifuge body 1213 in the circumferential direction as much as possible; thereby facilitating the upward flow of liquid along the centrifuge body 1213 and the downward flow of solid material along the centrifuge body 1213, thereby improving the separation efficiency.

[0081] In some embodiments, the number of guide elements 1214 can be 4-8. See also Figure 11 and Figure 14 In some embodiments, a plurality of grooves 12133 may be formed on the side of the centrifuge body 1213 facing the first mounting member 122, and the grooves 12133 of each centrifuge unit 121 are aligned, so that the corresponding grooves 12133 of all centrifuge units 121 can form a plurality of channels extending along the first mounting member 122. In this way, liquid flowing upward along the centrifuge body 1213 can enter and move towards the inlet / outlet liquid assembly 20 through the plurality of channels, which is beneficial to improving the efficiency of liquid movement towards the inlet / outlet liquid assembly 20, thereby improving the separation efficiency.

[0082] See Figure 11 and Figure 14 In some embodiments, the guide member 1214 can be arc-shaped, wherein the arc extends from the radial inner side of the centrifugal body 1213 to the radial outer side of the centrifugal body 1213 to achieve a better guiding effect.

[0083] See Figure 16 In some embodiments, when all centrifugal units 121 are fitted onto the first mounting member 122, the through holes 1212 of each centrifugal unit 121 are aligned axially, and the guide members 1214 of each centrifugal unit 121 are aligned. In such embodiments, it is advantageous for the solid-liquid mixture in the trough 1231 to flow rapidly through the through holes 1212 to each centrifugal unit 121 under the action of centrifugal force.

[0084] See Figure 11 and Figure 14In some embodiments, the centrifuge body 1213 may include a conical guide section 12131 and a connecting section 12132. The conical guide section 12131 is configured such that, under centrifugal force, liquid can flow along the surface of the conical guide section 12131 toward the inlet / outlet liquid assembly 20, and solid material can move along the surface of the conical guide section 12131 in the opposite direction to the liquid flow direction, so that the liquid and solid material in the solid-liquid mixture can be separated. The connecting section 12132 is sleeved on the first mounting member 122 and is configured to be circumferentially stationary relative to the first mounting member 122. This configuration allows the centrifuge body 1213 to rotate when the first mounting member 122 rotates with the second mounting member 123, and the separation of liquid and solid material is achieved through the different movement directions of liquid and solid material on the surface of the conical guide section 12131.

[0085] See Figure 11 and Figure 14 In some embodiments, the through hole 1212 and the flow guide 1214 may be provided in the tapered flow guide section 12131. The positioning and fitting part 1211 is provided in the connecting section 12132. This arrangement allows the solid-liquid mixture to flow through the through hole 1212 to the tapered flow guide section 12131, and then rotate synchronously with the centrifugal body 1213 in the circumferential direction under the guiding action of the flow guide 1214.

[0086] In some embodiments, the tapered guide section 12131 extends obliquely upward from its lower end toward the connecting section 12132.

[0087] See Figure 11 and Figure 14 In some embodiments, the groove 12133 may be formed on the side of the connecting segment 12132 facing the first mounting member 122.

[0088] See Figure 16 In some embodiments, two adjacent centrifugal units 121 are pressed together, and a gap is created between the conical guide sections 12131 of the two adjacent centrifugal units 121 by a guide member 1214 for fluid flow. By using the guide member 1214 to create a gap, it is easier to achieve a gap of only 1-2 mm between the two adjacent centrifugal units 121.

[0089] See Figure 2 , Figure 4 and Figure 6 In some embodiments, the movable element 13 can also be used to guide the separated solid material so that it can enter the collection unit 30 via the material outlet. In some embodiments, the separated solid material can enter the collection unit 30 under the centrifugal force of the centrifugal body 12 and the guiding force of the movable element 13.

[0090] See Figure 2 , Figure 4 or Figure 6 In some embodiments, the movable member 13 forms a movable guide surface 131, which allows solid material entering the movable member 13 to move along the movable guide surface 131 towards the solid material outlet 1102 under the action of centrifugal force. Thus, when the movable member 13 opens the solid material outlet 1102 of the centrifuge housing 11, the solid material can enter the solid material outlet 1102 of the centrifuge housing 11. This arrangement facilitates the movement of solid material entering the movable member 13 along the movable guide surface 131 towards the solid material outlet 1102, thereby improving the efficiency of solid material entering the collection member 30.

[0091] In some embodiments, a movable guide surface 131 is formed on the surface of the movable member 13 opposite to the second shell section 112. The movable guide surface 131 may be a tapered surface that extends radially outward from bottom to top.

[0092] See Figure 2 , Figure 4 or Figure 6 In some embodiments, the radial ends of the movable member 13 face the second shell section 112 respectively, and a sealing element is provided between the radial end face of the movable member 13 facing the second shell section 112 and the second shell section 112 to achieve sealing. In some embodiments, the sealing element can be a rubber sealing ring. In some embodiments, a sealing cavity 16 is formed between the movable member 13 and the second shell section 112.

[0093] See Figure 2 , Figure 4 or Figure 6 In some embodiments, the surface of the movable member 13 facing the second housing section 112 along its axial direction is adapted to the surface of the second housing section 112 facing the movable member 13. This arrangement makes the thickness of the sealing cavity 16 uniform in the radial direction, thereby facilitating the uniform application of pressure to the movable member 13 by the fluid within the sealing cavity 16 during the adjustment of the pressure within the sealing cavity 16 using the pressure regulating member 14.

[0094] In some embodiments, the surface of the movable member 13 facing away from the second shell section 112 along its axial direction includes a mating surface that mates with the third shell section 113, a movable guide surface 131, an annular surface, and a conical surface parallel to the second mounting member 123. These surfaces together form an annular receiving groove at the bottom of the centrifugal cavity 1101.

[0095] See Figure 16In some embodiments, the second shell section 112 may form multiple discharge guide surfaces 11211, each extending to a corresponding solid material outlet 1102. The discharge guide surfaces 11211 facilitate the flow of solid material into the solid material outlet 1102 under centrifugal force. In some embodiments, the discharge guide surfaces 11211 of the second shell section 112 have the same rotation direction as the guide member 1214 of the centrifugal unit 121.

[0096] See Figure 16 and Figure 21 In some embodiments, the second shell section 112 may form multiple mating parts 1121 for mating with the third shell section 113. Each mating part 1121 is formed between two adjacent solid material outlets 1102, and a discharge guide surface 11211 is formed on the surface of the mating part 1121 facing the centrifugal body 12. This arrangement facilitates both the assembly of the third shell section 113 and the second shell section 112 and the movement of solid material along the inner wall of the third shell section 113 towards the solid material outlet 1102 under centrifugal force.

[0097] See Figure 7 The third shell section 113 is pressed onto the mating part 1121, and the third shell section 113 and the second shell section 112 are pressed and sealed by the clamping part 114. A sealing part is provided on the side of the third shell section 113 facing the mating part 1121.

[0098] See Figure 6 and Figure 9 In some embodiments, the liquid inlet / outlet assembly 20 may include a feed member 21, a liquid outlet fitting 22, and a liquid suction member 23. The feed member 21 has a discharge port located within the feed chamber 1103, so that the solid-liquid mixture flowing out of the discharge port of the feed member 21 can enter the feed chamber 1103.

[0099] In some embodiments, the feed member 21 is disposed radially inside the first pipe 1111 to supply a solid-liquid mixture to the centrifuge chamber 1101; the liquid outlet fitting 22 is disposed radially outside the feed member 21, and the liquid outlet fitting 22 cooperates with the feed member 21 to form a liquid outlet channel 25 between the liquid outlet fitting 22 and the feed member 21; the liquid suction member 23 is disposed in the liquid storage chamber 24 and connected to the liquid outlet fitting 22, and the liquid suction member 23 is configured to draw the liquid separated by the centrifuge assembly 10 to the liquid outlet channel 25. This configuration allows the inlet and outlet liquid assembly 20 to both supply a solid-liquid mixture to the centrifuge chamber 1101 and draw out the separated liquid.

[0100] See Figure 6 and Figure 9 In some embodiments, the feed member 21 can be a pipe. The outlet of the feed member 21 is a side port of the pipe located inside the feed chamber 1103.

[0101] See Figure 6 and Figure 9 In some embodiments, the extension 1115 and the second cover 1113 together form a liquid storage cavity 24. See also Figure 9 In some embodiments, there is a gap between the liquid suction member 23 and the second cover member 1113, and a gap between the first tube member 1111 and the feed member 21, so that the centrifugal assembly 10 can rotate relative to the inlet / outlet liquid assembly 20. In some embodiments, the liquid temporary storage chamber 24 is located on one axial side of the centrifugal chamber 1101.

[0102] See Figure 9 and Figure 18 In some embodiments, the liquid suction member 23 can form multiple circumferentially distributed spiral channels 231, which are in fluid communication with the liquid outlet channel 25. When the centrifuge shell 11 rotates relative to the inlet / outlet liquid assembly 20, the spiral channels 231 can draw the liquid separated by the centrifuge assembly 10 into the liquid outlet channel 25. With the above arrangement, it is beneficial for the liquid separated in the liquid storage chamber 24 to enter the liquid outlet channel 25.

[0103] It is easy to understand that when the centrifuge shell 11 rotates relative to the inlet / outlet liquid assembly 20, it will cause the liquid in the liquid storage chamber 24 to rotate. Since the liquid and the spiral channel 231 rotate relative to each other, the liquid will be sucked into the spiral channel 231.

[0104] See Figure 14 and Figure 18 In some embodiments, the spiral channel 231 of the suction member 23 rotates in the opposite direction to the flow guide 1214 of the centrifugal unit 121, so that the liquid separated by the centrifugal unit 121 can be sucked into the liquid outlet channel 25.

[0105] See Figure 18 and Figure 19 In some embodiments, the liquid suction member 23 may include an annular body 232 and an annular cover plate 233. The annular body 232 is connected to the liquid discharge fitting 22, and a plurality of spiral grooves 2321 are formed on the side of the annular body 232 facing the annular cover plate 233 to form a plurality of spiral channels 231 together with the annular cover plate 233. The above-described configuration of the liquid suction member 23 facilitates manufacturing.

[0106] In some embodiments, the annular body 232 forms a conical surface 2322 on the side opposite to the annular cover plate 233, which is used to guide the liquid in the liquid storage chamber 24 to flow toward the inlet direction of the spiral channel 231; the annular cover plate 233 is connected to the feed member 21.

[0107] In some embodiments, the annular body 232 and the liquid outlet mating part 22 can be integrally molded parts. See also Figure 19In some embodiments, the width of the spiral groove 2321 located on the radially outer side of the annular body 232 is greater than its width located on the radially inner side of the annular body 232, so as to facilitate the entry of liquid in the liquid storage cavity 24 into the spiral channel 231.

[0108] See Figure 20 In some embodiments, the feed member 21 may include a first pipe section 211, a second pipe section 212, and a limiting part 213. The first pipe section 211 is disposed radially inside the centrifuge housing 11. After the solid-liquid mixture flows out from the first pipe section 211, it enters the centrifuge chamber 1101 through the feed hole 11111 on the centrifuge housing 11. The second pipe section 212 forms a liquid outlet channel 25 with the liquid outlet fitting 22. The limiting part 213 is disposed between the first pipe section 211 and the second pipe section 212 to axially limit the liquid suction member 23 to prevent the liquid suction member 23 from contacting the bottom wall of the liquid storage chamber 24.

[0109] See Figure 20 In some embodiments, the circumferential surface of the second pipe segment 212 includes multiple cut surfaces 2121 and multiple curved surfaces 2122, with adjacent curved surfaces 2122 connected by a cut surface 2121. See also Figure 22 The radial inner surface of the liquid outlet fitting 22 matches the curved surface 2122 of the second pipe section 212, and a gap is formed between the radial inner surface of the liquid outlet fitting 22 and the tangent surface 2121. These gaps form the liquid outlet channel 25.

[0110] See Figure 2 In some embodiments, the solid-liquid separation device 100 may further include a housing 50. The housing 50 is configured to form a receiving cavity 53; the centrifugal assembly 10 is disposed within the receiving cavity 53 and is rotatable relative to the housing 50; and the inlet / outlet liquid assembly 20 is disposed on the housing 50. By providing the housing 50, the centrifugal assembly 10 and the inlet / outlet liquid assembly 20 can be assembled on the housing 50.

[0111] See Figure 2 and Figure 4 In some embodiments, the outer casing 50 may include a casing body 51 and a detachable component 52 detachably connected to the casing body 51. The casing body 51 and the detachable component 52 together form a receiving cavity 53. When the detachable component 52 is removed from the casing body 51, the collecting component 30 can be removed from the casing body 51. This arrangement facilitates the removal of the collecting component 30 and the solid material contained therein using a robotic arm, which helps reduce the radiation exposure of operators from radioactive liquids and solid materials.

[0112] See Figure 2 , Figure 4 as well as Figure 23In some embodiments, the shell body 51 may include a bottom shell 511 and a shell cover 512 spaced apart. A collection component 30 is detachably disposed on the bottom shell 511, a drive assembly 40 is rotatably connected to the bottom shell 511, and an inlet / outlet liquid assembly 20 is disposed on the shell cover 512. A detachable component 52 is detachably connected to the shell cover 512 and the bottom shell 511, and the bottom shell 511, shell cover 512, and detachable component 52 together form a receiving cavity 53. When the detachable component 52 is removed from the shell cover 512 and the bottom shell 511, the collection component 30 can be removed from the shell body 51. The embodiments of this application, by configuring the shell body 51 as described above, facilitate a rational arrangement of the connection relationships between the various components and the shell body 51, ensuring that the components do not interfere with each other when performing their respective functions.

[0113] See Figure 4 In some embodiments, the bottom shell 511 may include a bottom shell body 5111 and a mounting member 5112 disposed radially inside the bottom shell body 5111. The mounting member 5112 and the bottom shell body 5111 together form a mounting groove 54, and the collection member 30 is disposed in the mounting groove 54. When the removable part 52 is removed from the cover 512 and the bottom shell 511, the collection member 30 can be removed from the mounting groove 54. This arrangement facilitates the installation and removal of the collection member 30.

[0114] In some embodiments, the bottom wall of the collecting member 30 and the bottom wall of the mounting groove 54 are respectively provided with through holes for allowing liquid remaining in the solid material in the collecting member 30 to flow into the bottom shell body 5111, so as to facilitate further separation of liquid remaining on the surface of the solid material. The bottom shell body 5111 is provided with an opening for allowing liquid entering the bottom shell body 5111 from the collecting member 30 to flow out.

[0115] See Figure 2 In some embodiments, the solid-liquid separation device 100 may further include a negative pressure suction line 60, which is disposed at the opening of the bottom shell body 5111 and is in fluid communication with the receiving cavity 53. This negative pressure line 60 is used to create a negative pressure environment in the receiving cavity 53 to extract the liquid from it. By using the negative pressure suction line 60 to extract the liquid from the receiving cavity 53, it is beneficial to recover as much liquid as possible.

[0116] See Figure 4 In some embodiments, the bottom wall of the bottom shell body 5111 forms a bottom shell annular groove 51111 for facilitating the flow of liquid entering the receiving cavity 53. This arrangement facilitates the removal of as much liquid as possible from the receiving cavity 53 through the negative pressure suction line 60, reducing residue. In some embodiments, the opening of the bottom shell body 5111 is located at the bottom shell annular groove 51111.

[0117] See Figure 9In some embodiments, the cover 512 is provided with a slot 5121, and the feed member 21 and the liquid outlet fitting 22 extend downward from the slot 5121. In some embodiments, the cover 512 is also provided with a feed groove 5122, which is in fluid communication with the feed member 21, and the solid-liquid mixture can enter the feed member 21 through the feed groove 5122.

[0118] See Figure 6 , Figure 9 and Figure 20 In some embodiments, the portion of the feed member 21 facing the feed trough 5122 forms a feed annular groove 2101 and a plurality of feed through holes 2102 in fluid communication with the feed annular groove 2101, so that the solid-liquid mixture in the feed trough 5122 can first enter the feed annular groove 2101 and then enter the feed member 21 through the plurality of feed through holes 2102. This arrangement facilitates the uniform entry of the solid-liquid mixture into the feed member 21 along the circumference of the feed member 21, thereby uniformly entering the feed chamber 1103, and thus uniformly entering the feed hole 11111 under the action of centrifugal force. The feed annular groove 2101 is specifically formed in the second pipe section 212.

[0119] In some embodiments, the second pipe section 212 further forms two sealing grooves 2123, which are disposed on both sides of the feed ring groove 2101 for providing a seal to prevent leakage of solid-liquid mixture entering the feed ring groove 2101.

[0120] See Figure 1 and Figure 2 In some embodiments, the solid-liquid separation device 100 may further include a feed pipe 70, which is disposed on the cover 512 and is in fluid communication with the feed ring groove 2101 for supplying solid-liquid mixtures into the feed tank 5122.

[0121] See Figure 6 and Figure 9 In some embodiments, the cover 512 is also provided with a liquid outlet groove 5123 and an annular groove 5124. The liquid outlet groove 5123 is in fluid communication with the liquid outlet channel 25 through the annular groove 5124, and the liquid drawn into the liquid outlet channel 25 can flow into the liquid outlet groove 5123 through the annular groove 5124. This arrangement helps to speed up the flow of liquid into the liquid outlet groove 5123.

[0122] See Figure 3 and Figure 4 In some embodiments, the solid-liquid separation device 100 may further include a liquid outlet pipe 80, which is disposed on the cover 512 and is in fluid communication with the liquid outlet tank 5123 for supplying liquid from the liquid outlet tank 5123.

[0123] See Figure 18 and Figure 19In some embodiments, the liquid outlet fitting 22 can be a pipe, and the end of the liquid outlet fitting 22 away from the liquid suction member 23 has a plurality of notches 221 to allow liquid in the liquid outlet channel 25 to enter the annular groove 5124. In some embodiments, a sealing member is provided between the liquid outlet fitting 22 and the cover 512 to prevent liquid from flowing outward through the gap between them.

[0124] See Figure 23 The cover 512 may include a cover body 5125 and a protrusion 5126 connected to the cover body 5125, and a slot 5121 penetrates the cover body 5125 and the protrusion 5126. A feed groove 5122, a liquid outlet groove 5123, and an annular groove 5124 are formed on the protrusion 5126.

[0125] The detachable component 52 includes an annular cover 521 and a first connector 522 disposed radially outward of the annular cover 521. The bottom shell 511 also includes a bottom shell connector 5113 connected to the bottom shell body 5111. The detachable component 52 is detachably connected to the bottom shell 511 via the first connector 522 and the bottom shell connector 5113. The detachable component 52 also includes a second connector 523 disposed radially inward of the annular cover 521; the second connector 523 is detachably connected to the cover body 5125.

[0126] See Figure 4 and Figure 23 In some embodiments, the solid-liquid separation device 100 may further include a dynamic seal 90, through which the bottom housing body 5111 is sealed to the drive shaft 41. The dynamic seal 90 may include a bushing 92 and a plurality of bearings 91. The bearings 91 are disposed on the bushing 92. The bushing 92 is sealed to the bottom housing body 5111, and the bearings 91 are sealed to the drive shaft 41.

[0127] In some embodiments, see Figure 23 The bottom wall of the bottom shell body 5111 has a through hole 51112, and the bushing 92 is disposed in the through hole 51112. In some embodiments, the bushing 92 may include a bushing connector 921 and a bushing body 922, a bearing 91 is disposed in the bushing body 922, and the bushing body 922 is disposed in the through hole 51112; the bushing connector 921 is formed at one end of the bushing body 922 near the bottom shell body 5111, the diameter of the bushing connector 921 is larger than the diameter of the through hole 51112, and the bushing connector 921 is sealed to the bottom shell body 5111.

[0128] In some embodiments, the bushing 92 is provided with a through hole 923, through which the drive shaft 41 can pass and extend into the receiving cavity 53.

[0129] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.
