[0050] The following will be combined Figures 1 to 10 The solid-liquid separation device and the sedimentation tank provided by the utility model are described in detail.

[0051] As Figure 1 , Figures 3 to 5As shown, the first aspect of the utility model provides a kind of solid-liquid isolation device 400.The solid-liquid isolation device 400 includes isolation component 410 and first drive component 420.Isolation component 410 is used to be arranged in sediment tank body 100, to separate sediment tank body 100 into upper space and lower space;Isolation component 410 has first position and second position;In first position, isolation component 410 is used to deposit semi-solid precipitate;In the second position, semi-solid precipitate falls into lower space.First drive component 420 is connected with isolation component 410, for driving isolation component 410 switches in first position and second position.

[0052] In the embodiment, by setting isolation component 410 with first position and second position, in first position, isolation component 410 can separate sediment tank body 100 into upper space and lower space, and can deposit semi-solid precipitate in the sewage of receiving upper space.In second position, upper space can be communicated with lower space, and isolation component 410 can pour semi-solid precipitate deposited in lower space.By setting first drive component 420, isolation component 410 can be switched in first position and second position, so that sediment tank body 100 can be deposited in upper part, and sludge removal is carried out in lower part, to realize continuous operation, and improve deposition efficiency.

[0053] In some embodiments, isolation component 410 includes a plurality of turnover plates 411;A plurality of turnover plates 411 are laid in sediment tank body 100 along left-right direction;First drive component 420 is connected with turnover plate 411, for driving adjacent two turnover plates 411 respectively left and right, so that opening is formed between adjacent two turnover plates 411, and opening is used for solid to fall into the lower space.By setting a plurality of turnover plates 411, not only can semi-solid precipitate be deposited in the junction between turnover plate 411, but also when semi-solid precipitate is poured into lower space, the disturbance of semi-solid precipitate to water in lower space can be reduced.

[0054] Further, turnover plate 411 is inclinedly arranged, and a plurality of turnover plates 411 are spliced in horizontal plane along left-right direction to form wave-shaped turnover structure, which can further reduce the disturbance of semi-solid precipitate to water in lower space.

[0055] For example, the first driving assembly 420 drives the adjacent flip plates 411 to move left and right respectively, and the adjacent two flip plates 411 are spliced to form a V-shaped recess, and the plurality of flip plates 411 are spliced to form a wave structure, and the semi-solid precipitate of the sewage in the upper space falls into the recess. The first driving assembly 420 drives the adjacent flip plates 411 to move left and right respectively in the opposite direction, and the bottom of the groove is opened, and the semi-solid precipitate falls into the lower space under the action of its own gravity, and the flip plates 411 can also prevent the sewage in the lower space from flowing back to the upper space.

[0056] As shown in Figure 3 Further, the first included angle α of the recess of the wave-shaped flip structure is not greater than 90°.

[0057] In some embodiments, the number of the first driving assemblies 420 is plural, and the plurality of first driving assemblies 420 correspond to the plurality of flip plates 411 one by one. In other words, one first driving assembly 420 drives one flip plate 411 to rotate. The rotation directions of the adjacent two first driving assemblies 420 are opposite.

[0058] As shown in Figures 3 to 5 In some other embodiments, the first driving assembly 420 includes a plurality of main gears 421 and a first driving structure 422. The plurality of main gears 421 are arranged along the left-right direction, and the adjacent two main gears 421 are connected in meshing. The plurality of main gears 421 correspond to the plurality of flip plates 411 one by one, and the main gear 421 is connected to the corresponding flip plate 411 through the connecting shaft 428. The first driving structure 422 is connected to at least one main gear 421, and is used to drive the adjacent two flip plates 411 to flip forward and backward respectively through the main gear 421. By arranging the plurality of main gears 421 along the left-right direction and connecting the adjacent two main gears 421 in meshing, all the main gears 421 can be driven to rotate by one first driving structure 422, and the rotation directions of the adjacent two main gears 421 are opposite, which is simple in structure and convenient to operate.

[0059] Further, the first driving structure 422 includes a first transmission member 423 and a first driving member 424. One end of the first transmission member 423 is connected to at least one main gear 421, and the other end of the first transmission member 423 is connected to the first driving member 424, which is used to drive at least one main gear 421 to rotate through the first transmission member 423, so that the adjacent two flip plates 411 are flipped left and right respectively. By arranging the first transmission member 423, the installation position of the first driving member 424 can be more diversified.

[0060] For example, the first driving member 424 includes a driving motor. Preferably, the first driving member 424 is a servo motor.

[0061] Exemplarily, the first transmission member 423 comprises a chain transmission structure or a belt transmission structure.

[0062] As shown in Figure 5 Further, the first transmission member 423 comprises a screw rod 426 and a transmission shaft 427. The screw rod 426 is connected with the at least one main gear 421. One end of the transmission shaft 427 is connected with the screw rod 426, and the other end is connected with the first driving member 424. Specifically, the servo motor, the transmission shaft 427 and the screw rod 426 are coaxially arranged. One end of the transmission shaft 427 is connected with the screw rod 426, and the other end is connected with the driving end of the servo motor. The servo motor drives the screw rod 426 to rotate through the transmission shaft 427. The screw rod 426 is connected with the at least one main gear 421, and can drive all the main gears 421 to rotate. The screw rod 426 drives the main gears 421 to prevent the force at the end of the main gears 421 from being transmitted to the end of the servo motor, thereby avoiding the problem that the servo motor automatically turns over as the weight of the semi-fixed sediment increases.

[0063] Further, the first driving structure 422 further comprises a speed change gear 425. The speed change gear 425 is connected with the at least one main gear 421, and the speed change gear 425 is connected with the first driving member 424 through the first transmission member 423. The first driving member 424 adjusts the rotating speed of the main gears 421 through the speed change gear 425. Specifically, the speed change gear 425 is connected with the screw rod 426 and the main gears 421, and adjusts the rotating speed of the main gears 421.

[0064] Exemplarily, the speed change gear 425 comprises a speed reduction gear or a speed up gear. Preferably, the speed change gear 425 is a speed reduction gear.

[0065] The second aspect of the utility model provides a sedimentation tank. The sedimentation tank comprises the solid-liquid isolation device 400 of any of the above embodiments.

[0066] Because the sedimentation tank comprises the solid-liquid isolation device 400, at least the above advantages are achieved.

[0067] As shown in Figure 1 and Figure 2 In some embodiments, the sedimentation tank further comprises a self-dredging device 500.

[0068] In some embodiments, the self-dredging device 500 comprises a shell 510, a concentric circular annular flow channel 520, and a plurality of dredging guide assemblies 530. The shell 510 is arranged at the bottom of the sedimentation tank body 100; the shell 510 has a polygonal cross section; the upper portion of the shell 510 has an opening, and the bottom of the shell 510 has a dredging outlet 511. The concentric circular annular flow channel 520 is arranged in the shell 510; the dredging outlet 511 is located on the inner side of the concentric circular annular flow channel 520; the cross section of the concentric circular annular flow channel 520 is a polygonal inscribed circle; the concentric circular annular flow channel 520 is tangent to the inner wall of the shell 510 at the position of the flow guide opening 521, and the plurality of flow guide openings 521 form a circulating flow in the concentric circular annular flow channel 520. The plurality of dredging guide assemblies 530 are arranged in the shell 510 and located on the outer side of the concentric circular annular flow channel 520; the plurality of dredging guide assemblies 530 correspond to the flow guide openings 521 one by one, and the dredging guide assemblies 530 guide the sediments on the outer side of the concentric circular annular flow channel 520 to the corresponding flow guide openings 521.

[0069] In the present embodiment, by arranging the shell 510 at the bottom of the sedimentation tank body 100, the self-dredging device 500 can be used to remove the sludge at the bottom of the sedimentation tank body 100. By arranging the concentric circular annular flow channel 520 inside the shell 510, and the cross section of the concentric circular annular flow channel 520 being a polygonal inscribed circle, and the concentric circular annular flow channel 520 being tangent to the inner wall of the shell 510 at the position of the flow guide opening 521, the sewage entering the concentric circular annular flow channel 520 from the flow guide opening 521 can form a circulating flow in the concentric circular annular flow channel 520, so that the sludge can be discharged into the dredging outlet 511 with the water flow. By arranging the dredging guide assemblies 530 in the shell 510 and on the outer side of the concentric circular annular flow channel 520, the sludge on the outer side of the concentric circular annular flow channel 520 can be removed, avoiding the occurrence of dredging dead angle and ensuring the dredging effect. The present embodiment can not use a microfilter when removing the sludge from the sedimentation tank body 100, avoiding the blockage of the filter screen of the microfilter by solid particles, ensuring the dredging effect while reducing the dredging cost.

[0070] As Figure 2As shown in the drawings, in some embodiments, the concentric circular annular flow channel 520 comprises a plurality of annular flow channels 522 and a plurality of flow guide plates 523. The plurality of annular flow channels 522 are arranged around the central axis of the shell 510 to splice to form a concentric circular structure, the cross section of the concentric circular structure is a circle inscribed by a polygon; the flow guide openings 521 are formed between two adjacent annular flow channels 522; the plurality of annular flow channels 522 are tangent to the sides of the polygon one by one. The plurality of flow guide plates 523 correspond to the plurality of annular flow channels 522 one by one; the flow guide plates 523 are connected to one end of the annular flow channels 522, and the flow guide plates 523 are arranged in a direction parallel to the side wall of the flow guide opening 521, so that the water flow enters the annular flow channel 522 along the tangent direction of the annular flow channel 522, and forms a circular flow in the annular flow channel 522. In this embodiment, by arranging the plurality of annular flow channels 522 around the central axis of the shell 510 to splice to form a concentric circular structure, the water flow entering the concentric circular structure can be made to flow as circularly as possible, ensuring the effect of automatic dredging. By arranging the flow guide plates 523 in a direction parallel to the side wall of the flow guide opening 521, the water flow can enter the annular flow channel 522 along the tangent direction of the annular flow channel 522, and form a circular flow.

[0071] As shown in the drawings, Figure 2 In some embodiments, the pollution guide assembly 530 comprises a guide baffle 531 and a pollution water spraying element 532. The guide baffle 531 is arranged obliquely between the two adjacent inner side walls of the shell 510, and is used to guide the sewage located outside the concentric circular annular flow channel 520 to the inside of the concentric circular annular flow channel 520 through the corresponding flow guide opening 521. The pollution water spraying element 532 is arranged outside the concentric circular annular flow channel 520, and the pollution water spraying element 532 and the corresponding flow guide opening 521 are located on the two sides of the corresponding guide baffle 531, and the pollution water spraying element 532 is used to spray water to the side of the guide baffle 531 facing the concentric circular annular flow channel 520. In this embodiment, by arranging the guide baffle between the two adjacent inner side walls of the shell 510, the accumulation of sludge at the corners of the two adjacent inner side walls can be avoided, and the water flow can also be guided to the flow guide opening 521. By arranging the pollution water spraying element 532 on the side of the guide baffle away from the flow guide opening 521, not only can the sludge accumulated at the guide baffle be removed, but the water flow discharged from the pollution water spraying element 532 can also flow towards the flow guide opening 521 through the guide baffle 531.

[0072] Further, the cross section of the shell 510 is a square. Of course, the cross section of the shell 510 can also be a pentagon, a hexagon or a heptagon, etc.

[0073] Further, the third included angle γ between the guide baffle 531 and the inner side wall of the shell 510 is 45°. The water flow sprayed by the pollution water spraying element 532 can be all guided to the flow guide opening 521.

[0074] Furthermore, the length L of the right-angled side of the right triangle formed by the guide baffle 531 and the inner wall of the outer casing 510 is greater than the diameter of the nozzle of the sewage spray component 532. This allows all the water sprayed from the sewage spray component 532 to be guided towards the inlet 521.

[0075] Preferably, the length L of the right-angled side is 1 to 2 times the diameter of the nozzle of the sewage spray component 532.

[0076] like Figure 1 and Figure 6 As shown, in some embodiments, the sedimentation tank further includes a water inlet device 200. The water inlet device 200 is located above the self-cleaning device 500; the water inlet device 200 includes a main water inlet pipe 210 and a branch water inlet pipe 220. One end of the main water inlet pipe 210 is connected to a water source. One end of the branch water inlet pipe 220 is connected to a water source, and the other end is connected to the other end of the main water inlet pipe 210; the branch water inlet pipe 220 has multiple outlets along its axial direction, and the multiple outlets are arranged at intervals. By connecting one end of the branch water inlet pipe 220 to the main water inlet pipe 210 and the other end to a water source, water can be introduced from two directions through the branch water inlet pipe 220. Combined with the multiple outlets arranged along the axial direction of the branch water inlet pipe 220, the flow velocity and flow rate of the water discharged from the water inlet device 200 into the sedimentation tank body 100 can be reduced, thus reducing the disturbance to the water in the sedimentation tank.

[0077] Furthermore, the water inlet device 200 also includes multiple drain pipes 230, which are spaced apart axially along and connected to the water inlet branch pipe 220. The drain pipes 230 are horizontally arranged and have drain outlets at both ends. This can further reduce disturbance to the water in the sedimentation tank body 100.

In this embodiment, by setting the surface water suction device 300, it is possible to simultaneously clean the sediment and guide the clean water in the left space to the right space, thereby achieving continuous operation and improving sedimentation separation efficiency.

[0080] In some embodiments, the surface water pumping device 300 includes a fixed partition plate 310 and a water pumping component 320. The front side of the fixed partition plate 310 is used to seal with the front inner wall of the sediment tank body 100, and the rear side of the fixed partition plate 310 is used to seal with the rear inner wall of the sediment tank body 100, so as to separate the tank body of the sediment tank body into a left space and a right space. The lower end of the water pumping component 320 is hinged to the fixed partition plate 310, the front side of the water pumping component 320 is used to seal with the front inner wall, the rear side of the water pumping component 320 is used to seal with the rear inner wall, and the upper end of the water pumping component 320 floats on the water surface of the left space, so that the water pumping component 320 floats with the water flow. The upper side of the floating body assembly 321 is provided with an overflow groove, and the overflow groove is used to overflow the surface water in the left space to the right space.

[0081] In this embodiment, by arranging the fixed partition plate 310, the sediment tank body 100 can be separated into a left space and a right space, wherein the left space can be used for sedimentation operation, and the right space is used for collecting clear water. In addition, the fixed partition plate 310 can also provide a mounting base for the water pumping component 320.
