[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-7 The present invention provides a technical solution:

[0031] An integrated wastewater treatment device includes a collection tank 1 and a solid-liquid separation mechanism 2. The solid-liquid separation mechanism 2 is used to separate solid waste into the collection tank 1 and to discharge the wastewater after separating solid waste into a sedimentation tank.

[0032] The solid-liquid separation mechanism 2 includes a turntable 21, baffles 22, and filter screens 23. An inlet pipe 4 for introducing wastewater into the solid-liquid separation mechanism 2 is located in the center of the turntable 21. The turntable 21 is rotatably mounted on the inlet pipe 4. Multiple sets of baffles 22 are evenly arranged on the side of the turntable 21 closest to the collection tank 1. Multiple sets of filter screens 23 are arranged on the outer periphery between adjacent baffles 22. The side of the baffles 22 away from the turntable 21 is fitted against the outer wall of the collection tank 1. The filter screens 23 between adjacent baffles 22 are connected to the collection tank 1. The outer wall of the collection box 1 forms a set of solid-liquid separation zones 11 with openings. The upper part of the collection box 1 is provided with a garbage inlet 5 for solid waste to enter. The outer wall of the collection box 1 is provided with an outer ring wall 6 that fits with the turntable 21. The outer ring wall 6 covers the outside of the partition 22 and has a water outlet 7 at the bottom. The outer wall of the collection box 1 is provided with an inner ring wall 8 that fits with the turntable 21. The inner ring wall 8 is located inside the partition 22 and has a water outlet 9 at the bottom. Each solid-liquid separation zone 11 is provided with a squeezing component 24 that pushes solid waste into the collection box 1 from the garbage inlet 5.

[0033] As can be seen from the above description, the rotation of turntable 21 can drive the solid-liquid separation zone 11 on turntable 21 to rotate. During the rotation, sewage will be thrown out from filter screen 23 and flow from outlet 7 to the next process, thereby completing solid-liquid separation. After the solid-liquid separation zone 11 rotates to be opposite to the garbage inlet 5, the squeezing component 24 pushes the solid garbage from the garbage inlet 5 into the collection box 1, thereby completing one cycle of solid-liquid separation in the solid-liquid separation zone 11.

[0034] Specifically, the extrusion assembly 24 includes an extrusion plate 241 slidably disposed in the solid-liquid separation zone 11 and a reciprocating screw 242 rotatably disposed on the turntable 21. The extrusion plate 241 has a through hole 10 in the middle, and a guide block is provided in the through hole 10 to cooperate with the reciprocating thread groove on the reciprocating screw 242. The extrusion plate 241 is slidably disposed on the reciprocating screw 242 through the cooperation of the guide block and the reciprocating thread groove. The turntable 21 is provided with a linkage structure that drives the reciprocating screw 242 in each solid-liquid separation zone 11 to rotate.

[0035] As can be seen from the above description, the rotation of the reciprocating screw 242 can drive the extrusion plate 241 to reciprocate within the solid-liquid separation zone 11. The sewage that enters through the inlet pipe 4 and flows into the solid-liquid separation zone 11 through the drain outlet 9 will be moved to the garbage inlet 5 by the turntable 21 in the solid-liquid separation zone 11 below the drain outlet 9. The extrusion plate 241 can then be moved to the side closest to the garbage inlet 5 by the rotation of the reciprocating screw 242, thereby pushing the solid garbage into the collection box 1. During the movement of the extrusion plate 241, the solid garbage can also be squeezed, causing the sewage in the solid garbage to be squeezed out and separated.

[0036] Specifically, one end of the reciprocating screw 242 extends to the outer end of the turntable 21 away from the collection box 1. The linkage structure includes a fixed gear plate 13 and a movable gear plate 12. The fixed gear plate 13 is fixedly sleeved on the water inlet pipe 4, and the movable gear plate 12 is fixed to the outer end of the reciprocating screw 242 and meshes with the fixed gear plate 13.

[0037] As can be seen from the above description, through the cooperation of the fixed toothed disc 13 and the moving toothed disc 12, during the rotation of the turntable 21, the moving toothed disc 12 will rotate in cooperation with the fixed toothed disc 13, thereby causing the reciprocating screw 242 in each set of solid-liquid separation zones 11 to rotate and drive the extrusion plate 241 to move, forming a direct drive structure.

[0038] Specifically, each solid-liquid separation zone 11 is equipped with a buffer plate 37, which is slidably mounted on a reciprocating screw 242. A spring 38 is mounted on the reciprocating screw 242 between the extrusion plate 241 and the buffer plate 37. The two ends of the spring 38 are respectively connected between the extrusion plate 241 and the buffer plate 37.

[0039] As can be seen from the above description, by setting up the buffer plate 37, when squeezing the solid waste in the solid-liquid separation zone 11, if a hard object is squeezed, a buffer can be formed, which is beneficial to protect the equipment. Furthermore, when the solid-liquid separation zone 11 rotates to be opposite to the waste inlet 5, the buffer plate 37 will generate kinetic energy under the action of the spring 38 and eject the waste into the collection box 1.

[0040] Specifically, one end of the water inlet pipe 4 extends into the inner ring wall 8, and the downward projection position of the drain outlet 9 is located on the side of the buffer plate 37 near the collection box 1 in the initial state.

[0041] As can be seen from the above description, the downward projection position of the drain outlet 9 is located on the side of the buffer plate 37 near the collection box 1 in the initial state. When the sewage with unseparated solid waste flows into the solid-liquid separation zone 11, the solid waste will not fall between the squeezing plate 241 and the buffer plate 37, thus preventing the solid waste from being unable to be pushed into the collection box 1 later.

[0042] Specifically, the area of ​​the garbage inlet 5 is larger than the projected area of ​​the solid-liquid separation zone 11. Guide slopes 40 are provided on both sides of the garbage inlet 5, and auxiliary slopes are provided on both sides of the buffer plate 37.

[0043] As can be seen from the above description, the area of ​​the garbage inlet 5 is larger than the projected area of ​​the solid-liquid separation zone 11, so that when the buffer plate 37 pushes the solid garbage into the collection box 1 and continues to rotate with the turntable 21, it has a space to be recovered by the reciprocating screw 242, so as to avoid the buffer plate 37 being stuck by the inner wall of the garbage inlet 5 during the rotation. The cooperation between the guide slope 40 and the auxiliary slope can increase the buffer space for the buffer plate 37 to move back.

[0044] Specifically, the outer periphery of the turntable 21 is provided with teeth 14, and the top of the collection box 1 is provided with a motor 15. The outer end of the output end of the motor 15 extends to the turntable 21 and is connected to a drive toothed disc 16, which meshes with the teeth 14.

[0045] As can be seen from the above description, the toothed disc can drive the turntable 21 to rotate through the motor 15, thereby causing the solid-liquid separation zone 11 to rotate.

[0046] Specifically, a filter sponge 17 is provided between adjacent partitions 22, and the filter sponge 17 is located on the outside of the filter screen 23.

[0047] As can be seen from the above description, after solid waste is filtered through filter screen 23, it can be filtered again through filter sponge 17, which facilitates the subsequent purification treatment of wastewater and speeds up the efficiency of wastewater treatment.

[0048] Specifically, the inner side of each set of partitions 22 is attached to the outer peripheral wall of the inner ring wall 8. A sealing plate 18 is provided between the outer ring wall 6 and the inner ring wall 8. The garbage inlet 5 passes through the sealing plate 18. The sealing plate 18 and the outer wall of the collection box 1 form a cavity 19. The lower part of the inner wall of the outer ring wall 6 is provided with an outer channel 30 that communicates with the cavity 19. The upper part of the outer wall of the inner ring wall 8 is provided with an inner channel 31 that communicates with the cavity 19.

[0049] As can be seen from the above description, the cooperation between the partition 22 and the inner ring wall 8 can prevent solid waste in the solid-liquid separation zone 11 from being discharged with the liquid (the inner side of the solid-liquid separation zone 11 is open radially, and the inner ring wall 8 can prevent solid waste from falling when the solid-liquid separation zone 11 rotates to the top). At the same time, it can increase the stability of the turntable 21 during rotation. After the two ends of the partition 22 are respectively attached to the inner ring wall 8 and the outer ring wall 6, the sewage can be discharged into the compartment 19 through the outer channel 30 and the inner channel 31.

[0050] Specifically, a garbage bin 36 is slidably installed inside the collection bin 1, and a hydraulic cylinder 34 is installed on the top of the collection bin 1. A pressure plate 35 is installed at one end of the output end of the hydraulic cylinder 34 that extends into the collection bin 1. The pressure plate 35 corresponds to the fixed opening of the garbage bin 36 and is initially located above the garbage inlet 5.

[0051] As can be seen from the above description, this method can periodically drive the hydraulic cylinder 34, causing the pressure plate 35 to compress the garbage in the garbage bin 36, thereby reducing the garbage volume in the garbage bin 36.

[0052] Please see Figure 1-7 As shown, Embodiment 1 of the present invention is as follows:

[0053] See Figure 1 , 2An integrated wastewater treatment device includes a collection tank 1 and a solid-liquid separation mechanism 2. In this invention, a protective box 3 is provided outside the collection tank 1 and the solid-liquid separation mechanism 2. The solid-liquid separation mechanism 2 is used to separate solid waste into the collection tank 1 and to discharge the wastewater after separating the solid waste into a sedimentation tank. The device of this invention discharges the wastewater after collecting solid waste into the sedimentation tank through the outlet 7. The sedimentation tank needs to carry out aerobic and anaerobic reactions on the wastewater. Sedimentation, aerobic reaction and anaerobic reaction are existing technologies, so they will not be described in detail.

[0054] See Figure 2 , 3 The solid-liquid separation mechanism 2 includes a turntable 21, baffles 22, and filter screens 23. The mesh size of the filter screens 23 can be selected according to the size of the solid waste to be separated at the location of the wastewater treatment. The turntable 21 is provided with an inlet pipe 4 in the middle to guide the wastewater into the solid-liquid separation mechanism 2. The inlet pipe 4 is fixed on the protective box 3. The turntable 21 is rotatably sleeved on the inlet pipe 4. The baffles 22 are arranged on the end face of the turntable 21 near the collection box 1, and multiple sets are evenly arranged along the circumference of the turntable 21. Multiple sets of filter screens 23 are arranged, and they are respectively arranged on the outer circumference between adjacent baffles 22. The side of the baffles 22 away from the turntable 21 is adjacent to the outer wall of the collection box 1. The adjacent partitions 22, the filter screens 23 between the partitions 22, and the outer wall of the collection box 1 form a set of solid-liquid separation zones 11 with openings. The upper part of the collection box 1 is provided with a garbage inlet 5 for solid waste to enter. The outer wall of the collection box 1 is provided with an outer ring wall 6 that fits with the turntable 21. The outer ring wall 6 covers the outside of the partitions 22 and has a water outlet 7 at the bottom. The outer wall of the collection box 1 is provided with an inner ring wall 8 that fits with the turntable 21. The inner ring wall 8 is located inside the partitions 22 and has a water outlet 9 at the bottom. Each solid-liquid separation zone 11 is provided with a squeezing component 24 that pushes solid waste into the collection box 1 from the garbage inlet 5.

[0055] See Figure 2 , 4In this embodiment, the extrusion assembly 24 includes an extrusion plate 241 slidably disposed in the solid-liquid separation zone 11 and a reciprocating screw 242 rotatably disposed on the turntable 21. The extrusion plate 241 has a through hole 10 in the middle, and a guide block is provided in the through hole 10 to cooperate with the reciprocating thread groove on the reciprocating screw 242. The extrusion plate 241 is slidably disposed in the solid-liquid separation zone 11 through the cooperation of the guide block and the reciprocating thread groove. When the solid-liquid separation zone 11 is rotated by the turntable 21 to face the drain outlet 9, the extrusion plate 241 is located on the side of the solid-liquid separation zone 11 furthest from the collection box 1 through the cooperation of the reciprocating screw 242 (initial state). In the initial state, when the solid-liquid separation zone 11 is rotated by the turntable 21 to face the garbage inlet 5 (at this time, the extrusion plate 241 in the solid-liquid separation zone 11 is in the final state of a cycle), the extrusion plate 241 is located on the reciprocating screw 242. The movable travel is closest to the collection box 1. The turntable 21 is equipped with a linkage structure that drives the reciprocating screw 242 in each solid-liquid separation zone 11 to rotate. One end of the reciprocating screw 242 extends to the outer end of the turntable 21 away from the collection box 1. The linkage structure includes a fixed toothed disc 13 and a movable toothed disc 12. The fixed toothed disc 13 is fixedly sleeved on the water inlet pipe 4. The movable toothed disc 12 is fixed to the outer end of the reciprocating screw 242 and meshes with the fixed toothed disc 13. The movable toothed disc 12 of each solid-liquid separation zone 11 is arranged around the fixed toothed disc 13 and meshes with the fixed toothed disc 13. When the turntable 21 rotates, the reciprocating screw 242 rotates and drives the extrusion plate 241 to work. It should be noted that, according to the above description, the extrusion plate 241 on the reciprocating screw 242 in each solid-liquid separation zone 11 completes one round trip on the reciprocating screw 242 after the turntable 21 rotates once.

[0056] See Figure 3 In this embodiment, the outer periphery of the turntable 21 is provided with teeth 14, and the top of the collection box 1 is provided with a motor 15. The outer end of the output end of the motor 15 extends to the turntable 21 and is connected to a drive toothed disc 16, which meshes with the teeth 14.

[0057] See Figure 4 In this embodiment, a filter sponge 17 is provided between adjacent partitions 22, and the filter sponge 17 is disposed on the outside of the filter screen 23.

[0058] See Figure 3 , 4 In this embodiment, the inner side of each set of partitions 22 is attached to the outer peripheral wall of the inner ring wall 8. The side of the partition 22 away from the inner ring wall 8 is spaced from the outer ring wall 6, so that the sewage can flow down the outer ring wall 6 after being thrown out by the filter sponge 17. A sealing plate 18 is provided between the outer ring wall 6 and the inner ring wall 8. The garbage inlet 5 passes through the sealing plate 18. One side of the partition 22 is attached to the sealing plate 18. The sealing plate 18 and the outer wall of the collection box 1 form a cavity 19 (see reference). Figure 7The lower part of the inner wall of the outer ring wall 6 is provided with an outer channel 30 that communicates with the cavity 19, and the upper part of the outer wall of the inner ring wall 8 is provided with an inner channel 31 that communicates with the cavity 19 (because when the solid-liquid separation zone 11 rotates to the upper part, the sewage will flow towards the inner ring wall 8, so in this embodiment the outer channel 30 is a semi-circular arc set at the lower part, and the inner channel 31 is a semi-circular arc set at the upper part); it should be noted that: an annular ring 32 is provided on the side of the turntable 21 near the outer ring wall 6, and an annular groove 33 is provided on the outer ring wall 6 for the annular ring 32 to rotate, so that the turntable 21, the outer ring wall 6, and the collection box 1 form a closed space.

[0059] See Figure 3 , 4 In this embodiment, a garbage bin 36 is slidably provided inside the collection bin 1, and a hydraulic cylinder 34 is provided on the top of the collection bin 1. A pressure plate 35 is provided at one end of the output end of the hydraulic cylinder 34 that extends into the collection bin 1. The pressure plate 35 is aligned with the opening of the garbage bin 36 and is initially located above the garbage inlet 5. A door can be provided on one side of the collection bin 1 to facilitate the removal of the garbage bin 36.

[0060] See Figure 4 , 5 6. In this embodiment, each solid-liquid separation zone 11 is slidably provided with a buffer plate 37. The buffer plate 37 is slidably sleeved on the reciprocating screw 242. The reciprocating screw 242 is located between the extrusion plate 241 and the buffer plate 37 and a spring 38 is sleeved thereon. The two ends of the spring 38 are respectively connected between the extrusion plate 241 and the buffer plate 37. The outer wall of the buffer plate 37 and the extrusion plate 241 is also in contact with the inner side of the filter screen 23. The filter screen 23 can also be cleaned during the sliding process of the extrusion plate 241 and the buffer plate 37. One end of the water inlet pipe 4 extends into the inner ring wall 8. The downward projection position of the drain outlet 9 is located on the side of the buffer plate 37 close to the collection box 1 in the initial state. The initial state means that the extrusion plate 241 is located on the side of the reciprocating screw 242 that is furthest away from the collection box in terms of its movable stroke. The area of ​​the garbage inlet 5 is larger than the projected area of ​​the solid-liquid separation zone 11. Guide ramps 40 are provided on both sides of the opening of the garbage inlet 5. The garbage inlet 5 also has a straight surface. Auxiliary ramps are provided on both sides of the buffer plate 37. When the buffer plate 37 is in the straight surface, it will suddenly pop out under the action of the spring 38 and push the solid garbage into the collection box 1. The turntable 21 continues to rotate. Since the opening range of the garbage inlet 5 is larger than the solid-liquid separation zone 11, the buffer plate 37 can slide back a certain distance within this range and then return to the solid-liquid separation zone 11 through the cooperation of the guide ramps 40.

[0061] In the process of using this invention: wastewater that has not undergone solid-liquid separation enters the inner ring wall 8 through the inlet pipe 4. After entering the inner ring wall 8, the wastewater flows through the drain outlet 9 of the inner ring wall 8 and falls into the solid-liquid separation zone 11 below the drain outlet 9. The motor 15 drives the gear disc 12 to rotate, the gear disc rotates the turntable 21 to rotate, and the turntable 21 rotates the solid-liquid separation zone 11 to rotate. The speed of the motor 15 can be adjusted according to the solid-liquid separation effect.

[0062] During the rotation of turntable 21, the moving gear will rotate through meshing with the fixed gear, thereby driving the reciprocating screw 242 to rotate. The rotation of the reciprocating screw 242 will drive the squeezing plate 241 to move towards the collection box 1 in the solid-liquid separation zone 11. Most of the sewage will be thrown out through the filter screen 23 and filter sponge 17 during the rotation of the solid-liquid separation zone 11 with turntable 21, and enter the partition cavity 19 through the outer channel 30, and finally flow into the sedimentation tank (existing technology) through the outlet 7. As turntable 21 continues to rotate, squeezing plate 241 will continuously drive buffer plate 37 to move. Buffer plate 37 will squeeze the solid waste in the solid-liquid separation zone to reduce the moisture content of the solid waste. When the solid-liquid separation zone 11 rotates to the waste inlet 5 through turntable 21, under the action of spring 38, buffer plate 37 will suddenly shift at one end and push the solid waste into the collection box 1, thereby completing the solid-liquid separation.

[0063] Turntable 21 continues to rotate, and reciprocating screw 242 will drive extrusion plate 241 and buffer plate 37 to move back until solid-liquid separation zone 11 is once again below drain outlet 9. At this time, extrusion plate 241 and buffer plate 37 are both in their initial state, ready to perform solid-liquid separation again.

[0064] When the solid waste in the trash can 36 is full, the pressure plate 35 can be driven down by the hydraulic cylinder 34 to compress the solid waste and complete the volume reduction. When the solid waste needs to be disposed of, the trash can 36 can be removed from the collection box 1.
