[0049] See also Figure 4In some embodiments, the bottom shell 511 may include a bottom shell body 5111 and a mounting member 5112 disposed radially inward of the bottom shell body 5111. The mounting member 5112 and the bottom shell body 5111 together form a mounting groove 54, and the collecting member 30 is disposed in the mounting groove 54. When the detachable member 52 is removed from the shell cover 512 and the bottom shell 511, the collecting member 30 can be taken out from the mounting groove 54. This arrangement facilitates the installation and removal of the collecting member 30.

[0050] 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 the 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 the liquid remaining on the surface of the solid material.

[0051] See also Figure 2 In some embodiments, the solid-liquid separation device 100 may further include a negative pressure suction pipeline 60, which is disposed in the bottom shell body 5111 and is in fluid communication with the accommodating chamber 53, and is used to form a negative pressure environment in the accommodating chamber 53 to extract the liquid in the accommodating chamber 53. By arranging the negative pressure suction pipeline 60 to extract the liquid in the accommodating chamber 53, it is beneficial to recover the liquid as much as possible.

[0052] See also Figure 4 In some embodiments, the bottom wall of the bottom shell body 5111 forms a bottom shell annular groove 51111 for the liquid entering the accommodating chamber 53 to converge; the negative pressure suction pipeline 60 is connected to the bottom shell annular groove 51111. This arrangement is conducive to completely extracting the liquid in the accommodating chamber 53 through the negative pressure suction pipeline 60 to reduce the residual. In some embodiments, the opening of the bottom shell body 5111 is set at the bottom shell annular groove 51111.

[0053] In some embodiments, the liquid inlet and outlet assembly 20 may include a feed member 21, a liquid outlet fitting member 22, and a liquid suction member 23. The feed member 21 is disposed on the radial inner side of the centrifugal assembly 10 to supply a solid-liquid mixture to the centrifugal assembly 10; the liquid outlet fitting member 22 is disposed on the radial outer side of the feed member 21, and the liquid outlet fitting member 22 cooperates with the feed member 21 to form a liquid outlet channel 25 between the liquid outlet fitting member 22 and the feed member 21; the liquid suction member 23 is configured to suck the liquid separated by the centrifugal assembly 10 to the liquid outlet channel 25. In this configuration, the liquid inlet and outlet assembly 20 can both supply a solid-liquid mixture to the centrifugal chamber 1101 and suck out the separated liquid.

[0054] In some embodiments, the liquid absorption component 23 is connected to the liquid discharge component 22.

[0055] See also Figure 6 and Fig. 9 In some embodiments, the feed member 21 may be a tube.

[0056] See also Fig. 9 and Fig.18 In some embodiments, the liquid absorbing member 23 may form a plurality of spiral channels 231 distributed along the circumferential direction, and the spiral channels 231 are in fluid communication with the liquid outlet channel 25. When the centrifugal assembly 10 rotates relative to the liquid inlet and outlet assembly 20, the spiral channels 231 can absorb the liquid separated by the centrifugal assembly 10 into the liquid outlet channel 25. The above arrangement facilitates the liquid separated in the liquid temporary storage chamber 24 to enter the liquid outlet channel 25.

[0057] See also Fig.18 and Fig.19 In some embodiments, the liquid absorbing member 23 may include an annular body 232 and an annular cover plate 233.

The above arrangement of the liquid absorbing member 23 facilitates processing.

[0058] In some embodiments, the annular body 232 and the liquid outlet fitting 22 may be integrally formed. Fig.19 In some embodiments, the width of the spiral groove 2321 located on the radial outer side of the annular body 232 is greater than the width of the spiral groove 2321 located on the radial inner side of the annular body 232 , so as to facilitate the liquid to enter the spiral channel 231 .

[0059] See also Fig. 20 In some embodiments, the feed member 21 may include a first pipe segment 211, a second pipe segment 212, and a limiting portion 213. The first pipe segment 211 is disposed on the radial inner side of the centrifugal assembly 10, and a liquid outlet channel 25 is formed between the second pipe segment 212 and the liquid outlet fitting 22. The limiting portion 213 is disposed between the first pipe segment 211 and the second pipe segment 212, and is used to axially limit the liquid suction member 23.

[0061] See also Fig. 9In some embodiments, the shell cover 512 is provided with a slot 5121, and the feed piece 21 and the liquid outlet matching piece 22 extend downward from the slot 5121; the shell cover 512 is also provided with a feed slot 5122, which is in fluid communication with the feed piece 21. The solid-liquid mixture can enter the feed piece 21 through the feed slot 5122.

[0062] See also Figure 6 , Fig. 9 and Fig. 20 In some embodiments, the portion of the feed member 21 facing the feed groove 5122 may be formed with 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 groove 5122 can first enter the feed annular groove 2101 and then enter the feed member 21 through the plurality of feed through holes 2102. Such a configuration is conducive to the solid-liquid mixture entering the feed member 21 uniformly along the circumference of the feed member 21, thereby uniformly entering the feed cavity 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.

[0063] In some embodiments, the second pipe section 212 further forms two sealing grooves 2123 disposed on both sides of the feed ring groove 2101 for setting sealing members to prevent leakage of the solid-liquid mixture material entering the feed ring groove 2101 .

[0064] See also Figure 1 and Figure 2 In some embodiments, the solid-liquid separation device 100 may further include a feed pipeline 70 , which is disposed on the shell cover 512 and is fluidically connected to the feed ring groove 2101 , for supplying the solid-liquid mixture material into the feed groove 5122 .

The liquid sucked into the liquid outlet channel 25 can flow into the liquid outlet groove 5123 through the annular groove 5124. Such a configuration is conducive to accelerating the speed at which the liquid flows into the liquid outlet groove 5123.

[0066] See also Figure 3 and Figure 4 In some embodiments, the solid-liquid separation device 100 may further include a liquid outlet pipeline 80 , which is disposed on the shell cover 512 and is fluidically connected to the liquid outlet tank 5123 , for allowing the liquid in the liquid outlet tank 5123 to flow out.

In some embodiments, a sealing member is provided between the liquid outlet fitting 22 and the shell cover 512 to prevent the liquid from flowing outward through the gap between the two.

[0068] See also Fig.23 The shell cover 512 may include a cover body 5125 and a protrusion 5126 connected to the cover body 5125 , and the groove 5121 penetrates the cover body 5125 and the protrusion 5126 .

[0070] See also Figures 2 to 6 In some embodiments, the centrifugal assembly 10 may include a centrifugal housing 11, a centrifugal body 12, a movable part 13, and a pressure regulating part 14. The centrifugal housing 11 is configured to form a centrifugal chamber 1101, and a plurality of solid material outlets 1102 are circumferentially arranged on the radial outer side of the centrifugal housing 11 for allowing the solid material in the centrifugal chamber 1101 to enter the collecting part 30; the centrifugal body 12 is arranged in the centrifugal chamber 1101, and is used to rotate together with the centrifugal housing 11 to separate the solid-liquid mixed material; the movable part 13 is movably arranged in the centrifugal chamber 1101; and the pressure regulating part 14 is arranged in the centrifugal housing 11.

[0071] See also Figure 2 , Figure 4 and Figure 6In some embodiments, the driving 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 for opening a plurality of solid material outlets 1102 and a second position for closing a plurality of solid material outlets 1102; when the movable member 13 opens a plurality of solid material outlets 1102, the solid material separated in the centrifugal chamber 1101 can enter the collecting member 30 through the plurality of solid material outlets 1102 under the action of centrifugation. In the embodiment of the present application, the driving 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 for opening a plurality of solid material outlets 1102 and a second position for closing a plurality of solid material outlets 1102, thereby enabling the solid material outlets 1102 to be opened or closed, so as to facilitate timely delivery of the separated solid material into the collecting member 30.

[0072] In some embodiments, the movable member 13 and the centrifugal housing 11 may form a sealed chamber 16, and the pressure regulating member 14 may be used to regulate the pressure in the sealed chamber 16. By regulating the pressure in the sealed chamber 16, the movable member 13 can move between the first position and the second position, thereby enabling the solid material outlet 1102 to be opened or closed, so as to facilitate timely delivery of the separated solid material to the collecting member 30.

[0073] See also Figure 2 , Figure 4 or Figure 6 In some embodiments, the pressure regulating member 14 may include a first liquid inlet channel 141, a liquid outlet channel 142, a valve 143, and a second liquid inlet channel 144. The first liquid inlet channel 141 is formed in the centrifugal housing 11, and is used to provide fluid to the sealed cavity 16; the liquid outlet channel 142 is formed in the centrifugal housing 11, and is used for the fluid in the sealed cavity 16 to flow out; the valve 143 is used to close or open the liquid outlet channel 142; the second liquid inlet channel 144 is formed in the centrifugal housing 11, and is used to provide fluid to apply pressure to the valve 143, so that the valve 143 opens the liquid outlet channel 142, so that the fluid in the sealed cavity 16 can flow out through the liquid outlet channel 142, so that the movable member 13 can move from the second position of closing the plurality of solid material outlets 1102 to the first position of opening the plurality of solid material outlets 1102.

[0074] In some embodiments, the centrifugal housing 11 forms a channel, one end of which passes through the centrifugal housing 11, and the other end of which is in fluid communication with the liquid outlet channel 142, and the valve 143 is disposed in the channel. The valve 143 includes a valve body 1431, a valve switch 1432, and a reset member. The valve body 1431 is fixedly disposed in the channel, and the valve body 1431 forms a valve channel 14311, and the valve channel 14311 connects the liquid outlet channel 142 with the accommodating chamber 53. The valve switch 1432 is movably disposed in the channel, and the reset member is used to provide the valve switch 1432 with a force to move toward the valve body 1431, so that the valve switch 1432 closes the valve channel 14311 of the valve body 1431, and disconnects the passage between the valve channel 14311 and the liquid outlet channel 142. When the fluid enters the second liquid 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 liquid outlet channel 142. At this time, the fluid in the sealing chamber 16 can enter the valve channel 14311 through the liquid outlet channel 142 and flow to the outside of the centrifugal shell 11 (for example, flow into the accommodating chamber 53 formed by the outer shell 50 mentioned below).

[0101] The connecting section 1234 forms a groove with an upper opening, and the first cover 1112 is embedded in the groove. The first cover 1112 and the connecting section 1234 are sealed by a sealing ring to prevent liquid from entering the bottom of the groove.

[0102] See also Figures 14 to 17 In some embodiments, each centrifugal unit 121 is provided with a plurality of through holes 1212, and each through hole 1212 is respectively located between two material troughs 1231, so that the solid-liquid mixture in the material trough 1231 can flow to each centrifugal unit 121 through the through hole 1212 under the action of centrifugal force, which is beneficial to improving the separation efficiency of the centrifugal unit 121.

[0103] 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 that the solid-liquid mixture entering the trough 1231 can flow to each centrifugal unit 121 through the through hole 1212 of each centrifugal unit 121 under the action of centrifugal force.

In such an embodiment, it is beneficial to enable the solid-liquid mixture in the trough 1231 to quickly flow to each centrifugal unit 121 through the through holes 1212 under the action of centrifugal force.

[0109] See also Fig.11 and Fig.14In some embodiments, the centrifugal body 1213 may include a conical guide section 12131 and a connecting section 12132. The conical guide section 12131 is configured to enable the liquid to flow toward the inlet and outlet liquid assembly 20 along the surface of the conical guide section 12131 under the action of centrifugal force, and enable the solid material to move in the direction opposite to the liquid flow direction along the surface of the conical guide section 12131, so that the liquid and the 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 relatively stationary with the first mounting member 122 along the circumferential direction. This configuration enables the centrifugal body 1213 to rotate when the first mounting member 122 rotates with the second mounting member 123, and at the same time, the liquid and the solid material are separated by the different movement directions of the liquid and the solid material on the surface of the conical guide section 12131.

[0110] join Fig.11 and Fig.14 In some embodiments, the through hole 1212 and the guide member 1214 can be disposed in the conical guide section 12131. The positioning fitting portion 1211 is disposed in the connecting section 12132.

[0114] See also Figure 2 , Figure 4 and Figure 6 In some embodiments, the movable member 13 can also be used to guide the separated solid material so that the separated solid material can enter the collecting member 30 through the material outlet. In some embodiments, the separated solid material can enter the collecting member 30 under the centrifugal action of the centrifugal body 12 and the guiding action of the movable member 13.

[0115] See also Figure 2 , Figure 4 or Figure 6 In some embodiments, the movable member 13 forms a movable guide surface 131, and the movable guide surface 131 can enable the solid material entering the movable member 13 to move along the movable guide surface 131 toward the solid material outlet 1102 under the action of centrifugal force, so that when the movable member 13 opens the solid material outlet 1102 of the centrifugal housing 11, the solid material can enter the solid material outlet 1102 of the centrifugal housing 11. Such a configuration is conducive to the solid material entering the movable member 13 to move along the movable guide surface 131 toward the solid material outlet 1102, which is conducive to improving the efficiency of the solid material entering the collecting member 30.

[0116] In some embodiments, the movable guide surface 131 is formed on the surface of the movable member 13 facing away from the second shell segment 112 . The movable guide surface 131 may be a conical surface that extends obliquely from bottom to top toward the radial outside.

In some embodiments, the seal may be a rubber seal ring.

[0118] See also Figure 2 , Figure 4 or Figure 6 In some embodiments, the surface of the movable member 13 facing the second shell segment 112 along the axial direction thereof matches the surface of the second shell segment 112 facing the movable member 13. This arrangement makes the thickness of the sealing cavity 16 uniform along the radial direction, and further makes it easier for the fluid in the sealing cavity 16 to uniformly apply pressure to the movable member 13 during the process of adjusting the pressure in the sealing cavity 16 by the pressure adjusting member 14.

[0119] In some embodiments, the surface of the movable part 13 along its axial direction facing away from the second shell segment 112 includes a mating surface that cooperates with the third shell segment 113, a movable guide surface 131, an annular surface, and a conical surface parallel to the second mounting member 123, and these surfaces together form an annular receiving groove at the bottom of the centrifugal chamber 1101.

[0120] See also Fig.16In some embodiments, the second shell segment 112 may form a plurality of discharge flow guide surfaces 11211, each of which extends to a corresponding solid material outlet 1102. The flow guide of the discharge flow guide surface 11211 facilitates solid materials to enter the solid material outlet 1102 under the action of centrifugal force. In some embodiments, the discharge flow guide surface 11211 of the second shell segment 112 has the same rotation direction as the flow guide member 1214 of the centrifugal unit 121.

Each fitting 1121 is formed between two adjacent solid material outlets 1102, and a discharge guide surface 11211 is formed on the surface of the fitting 1121 facing the centrifugal body 12. Such a configuration is not only conducive to the assembly of the third shell segment 113 with the second shell segment 112, but also conducive to the solid material moving toward the solid material outlet 1102 along the inner wall of the third shell segment 113 under the action of centrifugal force. Figure 7 The third shell segment 113 is pressed on the fitting 1121, and the third shell segment 113 and the second shell segment 112 are pressed and sealed by the pressing member 114. A sealing member is provided on one side of the third shell segment 113 facing the fitting 1121.

[0122] See also Figure 6 and Fig. 9 In some embodiments, the extension portion 1115 and the second cover member 1113 together form a liquid temporary storage chamber 24. Fig. 9 In some embodiments, there is a gap between the liquid absorbing member 23 and the second cover member 1113, and there is a gap between the first tube member 1111 and the feed member 21, so that the centrifugal assembly 10 can rotate relative to the liquid inlet and outlet assembly 20. In some embodiments, the liquid temporary storage chamber 24 is located on one axial side of the centrifugal chamber 1101. In some embodiments, the liquid absorbing member 23 is disposed in the liquid temporary storage chamber 24.

The above arrangement facilitates the liquid separated in the liquid temporary storage chamber 24 to enter the liquid outlet channel 25.

[0124] It is easy to understand that when the centrifugal housing 11 rotates relative to the liquid inlet and outlet assembly 20 , the liquid in the liquid temporary storage chamber 24 will be driven to rotate. Since the liquid and the spiral channel 231 form a relative rotation, the liquid will be sucked into the spiral channel 231 .

[0125] See also Fig.14 and Fig.18 In some embodiments, the spiral channel 231 of the liquid absorbing member 23 and the flow guide member 1214 of the centrifugal unit 121 have opposite rotation directions, so that the liquid separated by the centrifugal unit 121 can be sucked into the liquid outlet channel 25 .
