[0003] The patent with the publication number CN115304141B discloses a non-powered high-efficiency solid-liquid separation device, including an outer cylinder, an inner cylinder, a stirring mechanism and a driving turbine. The outer cylinder is arranged vertically, with the bottom as a sedimentation area, the middle as an installation area, and the top as a water outlet area; the inner cylinder is coaxially arranged in the installation area, with a water inlet connected to the external water source at the bottom, and the top is connected to the water outlet area, and a sedimentation gap is formed between the cylinder wall of the inner cylinder and the cylinder wall of the outer cylinder, and the sedimentation gap connects the water outlet area and the sedimentation area; the stirring mechanism is coaxially arranged in the inner cylinder; the driving turbine is arranged on the rotating shaft of the stirring mechanism and faces the water inlet to drive the stirring mechanism to rotate; the driving turbine and the rotating shaft of the stirring mechanism are axially slidably matched to approach or move away from the water inlet.

[0023] Example 1: Solid-liquid separation fluidized bed, refer to Figure 1-Figure 4 , including: an outer cylinder 1; an inner cylinder 2, which is coaxially arranged in the outer cylinder 1, and a gap is set between the inner cylinder 2 and the outer cylinder 1 to form a sedimentation channel for sediments, and the inner cylinder 2 is provided with a plurality of through holes of the same height, which are used to discharge the sediments inside it; a water guide shell 3, which is connected to the bottom of the inner cylinder 2, and is used to guide the water to be treated. The water guide shell 3 is set in a gourd shape, and the middle and lower parts are both bundled mouth structures, and the middle and lower parts of the water guide shell 3 have the same diameter, which is used to ensure that the water flow speed of the water to be treated is the same when passing through the middle and lower parts of the water guide shell 3. The bottom of the water guide shell 3 is connected with a water inlet pipe 4, which passes through the outer cylinder 1, and the water inlet pipe 4 is connected to an external water source; a stirring member 5, which is rotatably connected to the top of the outer cylinder 1 and is coaxially arranged in the inner cylinder 2, and the bottom end of the stirring member 5 is fixedly connected to a first turbine 6, and the first turbine 6 is coaxially arranged in the water guide shell 3; a connecting rod 7, which is fixedly connected to the bottom side of the first turbine 6, and a cavity is set in the connecting rod 7. A fixing ring 8 is fixedly connected to the bottom, and a connecting column 9 is rotatably connected to the fixing ring 8. A rotating disk 10 fixed to the top of the connecting column 9 is rotatably connected in the cavity of the connecting rod 7. A torsion spring 11 is fixedly connected between the fixing ring 8 and the rotating disk 10. A second turbine 12 is fixedly connected to the bottom end of the connecting column 9. The second turbine 12 is rotated by the impact of the water to be treated to assist the rotation of the first turbine 6; the second turbine 12 is coaxially arranged in the water guide shell 3, and the distance between the first turbine 6 and the middle beam opening structure of the water guide shell 3 is the same as the distance between the second turbine 12 and the lower beam opening structure of the water guide shell 3, which is used to ensure that the first turbine 6 and the second turbine 12 are subjected to the same impact force of the water to be treated. The mud discharge component is arranged on the outer wall of the inner cylinder 2, which is used to seal the through hole of the inner cylinder 2 and discharge the residual sediment therein at a regular time, and the difference in rotational resistance between the first turbine 6 and the second turbine 12 when they are impacted by the water to be treated is used to control the mud discharge component to process the sediment in the inner cylinder 2.

[0024] In the above scheme, the main purpose is to use water as the driving force to mix the treated water and the reagent, and the main purpose is to save energy consumption, thereby reducing the cost of water treatment. The outer cylinder 1 is a closed shell, and a manhole is provided on the top of the outer cylinder 1, which is convenient for the staff to observe the situation inside the outer cylinder 1 and facilitate later maintenance. The outer cylinder 1 is fixedly connected to the support frame to ensure that the outer cylinder 1 is in a vertical state. The bottom of the outer cylinder 1 is a sedimentation area, and the top of the outer cylinder 1 is a water outlet area, wherein the sedimentation area of ​​the outer cylinder 1 is connected to a sewage pipe, and a valve is installed on the sewage pipe, and the water outlet area of ​​the outer cylinder 1 is connected to a drain pipe, and a valve is installed on the drain pipe, and the inner cylinder 2 is fixedly connected to the inner wall of the outer cylinder 1 through a mounting frame, and The inner cylinder 2 is coaxially arranged with the outer cylinder 1 to enhance the stability of the structure. A sedimentation gap is formed between the inner cylinder 2 and the outer cylinder 1. The upper part of the inner cylinder 2 is connected to the water outlet area of ​​the outer cylinder 1, and the diameter of the inner cylinder 2 gradually decreases from top to bottom to reduce the disturbance of the sediment. The inner cylinder 2 is provided with through holes with equal circumferential spacing and the same height. The through holes of the inner cylinder 2 are used to discharge the sediment accumulated in the inner cylinder 2 into the sedimentation area of ​​the outer cylinder 1. The water guide shell 3 is connected to the lower part of the inner cylinder 2. The lower end of the water guide shell 3 is connected to the water inlet pipe 4. The water inlet pipe 4 passes through the outer cylinder 1 and is connected to the external water source. The water to be treated flows into the inner cylinder 2 through the water inlet pipe 4 and the water guide shell 3. The water to be treated is mixed with the reagent and formed in the inner cylinder 2. The stirring member 5 mainly includes a rotating rod and a stirring rod. The rotating rod of the stirring member 5 is rotatably connected to the top of the outer cylinder 1. A plurality of stirring rods are arranged on the rotating rod of the stirring member 5 at intervals. The specific number, distribution and shape of the stirring rods are modified according to actual needs to form multiple stirring layers. The stirring member 5 is used to accelerate the mixing efficiency of the agent and the water to be treated. The first turbine 6 is fixed to the lower end of the rotating rod of the stirring member 5. The first turbine 6 rotates after being impacted by water. The first turbine 6 drives the stirring member 5 to rotate synchronously. The stirring member 5 is used to mix the water to be treated and the agent in the inner cylinder 2. The connecting rod 7 is fixed to the lower side of the first turbine 6, and the connecting rod 7 is coaxial with the rotating rod of the stirring member 5. It is arranged that when the water to be treated flows upward along the water guide shell 3, it simultaneously impacts the first turbine 6 and the second turbine 12 to rotate, and the second turbine 12 is conducive to the rotation of the connecting rod 7 assisted by the rotating disk 10 and the torsion spring 11, so as to realize the use of water to synchronously drive the first turbine 6 and the second turbine 12 to drive the stirring member 5 to rotate circumferentially. The mud discharge component is arranged between the outer cylinder 1 and the inner cylinder 2. The mud discharge component is used to block the through hole of the inner cylinder 2, so that the sediment moves upward along the inner cylinder 2 driven by the water flow, and the difference in relative rotation between the first turbine 6 and the second turbine 12 is used to change the sealing state of the mud discharge component to the inner cylinder 2, so that the sediment remaining in the inner cylinder 2 is discharged into the sedimentation area of ​​the outer cylinder 1.

[0025] Working process: when the treated water passes through the water inlet pipe 4 and flows upward along the water guide shell 3, the treated water impacts the first turbine 6 and the second turbine 12 to rotate. The first turbine 6 drives the stirring member 5 to rotate circumferentially, fully mixes the treated water and the reagent in the inner tube 2 and generates precipitation. The precipitation rises with the water flow in the inner tube 2 to reach the drainage area of ​​the outer tube 1. Under the action of gravity, the precipitation moves downward through the sedimentation gap between the outer tube 1 and the inner tube 2 and finally sinks to the bottom of the outer tube 1. When the water impacts the second turbine 12, the second turbine 12 drives the connecting column 9 and the rotating disk 10 to rotate synchronously. The second turbine 12 cooperates with the rotating disk 10 through the torsion spring 11 to drive the connecting rod 7 to rotate synchronously. The torsion of the torsion spring 11 is greater than the resistance of the circumferential rotation of the stirring member 5. The water in the upper drainage area of ​​the outer tube 1 is discharged through the drainage pipe, and the staff opens the valve of the sewage pipe at the bottom of the outer tube 1 at a regular time to discharge the sediment settled at the bottom of the outer tube 1.

[0026] Reference Figure 5 and Figure 7 The mud discharge assembly includes: a sealing ring 13, which is sealingly slidably connected to the outer wall of the inner tube 2, and the sealing ring 13 is used to seal the through hole of the inner tube 2. The outer wall of the inner tube 2 is fixedly connected with at least two fixing seats 131, and the fixing seat 131 is slidably connected with a sliding rod 132 whose bottom end is fixed to the sealing ring 13, and there is friction damping between the sliding rod 132 and the fixing seat 131, which is used to reduce the moving speed of the sliding rod 132; the sliding rod 132 is slidably connected with a sliding plate 14, and a tension spring 15 is fixed between the sliding plate 14 and the sealing ring 13; a driving component is arranged between the connecting rod 7 and the connecting column 9, and is used to change the position of the sealing ring 13 according to the difference in speed between the first turbine 6 and the second turbine 12, so as to release the through hole of the inner tube 2.

[0027] Reference Figure 6-Figure 8The driving component includes: a spline rod 16, which is coaxially arranged in the cavity of the connecting rod 7, the connecting column 9 is provided with a spline blind hole, the bottom of the spline rod 16 is provided with a spline, the spline at the bottom of the spline rod 16 is limited and slid in the spline blind hole of the connecting column 9, and the top of the spline rod 16 is provided with at least two spiral guide grooves; a limiting column 17, the number of which is consistent with the spiral guide groove on the spline rod 16, the limiting column 17 is fixed to the inner wall of the cavity of the connecting rod 7, and the limiting column 17 and the spiral guide groove are limited and slidably matched; a first telescopic rod 18, which is fixed in the cavity of the connecting rod 7, and the first telescopic rod 18 The telescopic end is rotatably connected to the spline rod 16, the first telescopic rod 18 is filled with hydraulic oil, a connecting ring 19 is fixedly connected to the outer side of the stirring member 5, an oil guide pipe is connected between the first telescopic rod 18 and the connecting ring 19, the connecting ring 19 is arranged as an inner ring and an outer ring, an oil storage chamber is arranged between the inner ring and the outer ring of the connecting ring 19, the inner ring of the connecting ring 19 is fixedly connected to the stirring member 5, the outer ring of the connecting ring 19 is rotatably connected to the inner ring, the fixed seat 131 is fixedly connected to the second telescopic rod 20, the telescopic end of the second telescopic rod 20 is fixedly connected to the sliding plate 14, and an oil guide pipe is connected between the second telescopic rod 20 and the connecting ring 19.

[0028] In the above scheme, the main purpose is to avoid the gradual increase of sediment in the inner cylinder 2, thereby reducing the obstruction of the sediment to the stirring member 5, thereby ensuring the rotation efficiency of the stirring member 5, and achieving full mixing of the reagent and the water to be treated. The sealing ring 13 is slidably connected to the outer wall of the inner cylinder 2, and the outer wall of the inner cylinder 2 is fixedly connected to the limiting ring. The limiting ring is used to limit the lower side of the sealing ring 13. The sealing ring 13 can only slide up and down along the inner cylinder 2, and the sealing ring 13 is located at the through hole of the inner cylinder 2 and seals it. Initially, the sealing ring 13 seals the through hole of the inner cylinder 2. After the water to be treated flows into the inner cylinder 2, the water to be treated cannot overflow from the through hole of the inner cylinder 2, thereby avoiding disturbance of the sediment at the bottom of the outer cylinder 1. There are two fixed seats 131 in total. The two fixed seats 131 are symmetrically fixed to the outer wall of the inner cylinder 2. The two fixed seats 131 are located on the upper side of the through hole of the inner cylinder 2. The tension spring 15 between the sliding plate 14 and the sealing ring 13 It is sleeved on the outer side of the adjacent sliding rod 132, and two spiral guide grooves with the same spiral direction are arranged on the outer side surface of the upper part of the spline rod 16, and two symmetrical limiting columns 17 are fixedly connected in the cavity of the connecting rod 7, and the two limiting columns 17 are respectively slidingly matched with the two spiral guide grooves on the spline rod 16. When the agitator 5 rotates, the outer ring of the connecting ring 19 is stationary relative to the inner cylinder 2, and the agitator 5 drives the inner ring of the connecting ring 19 to rotate synchronously. The sediment in the inner cylinder 2 increases the resistance of the agitator 5 and the first turbine 6 when they rotate. When the impact force on the first turbine 6 and the second turbine 12 is the same, an angle difference will appear between the first turbine 6 and the second turbine 12. The angle difference between the first turbine 6 and the second turbine 12 is used to release the sealing ring 13 from the through hole of the inner cylinder 2, so that the sediment in the inner cylinder 2 is discharged from the through hole thereon, reducing the influence of the sediment on the rotation of the agitator 5 and the first turbine 6.

[0029] Working process: With the use of the device, the water to be treated is mixed with the reagent to produce sediment, among which part of the sediment is too large and it is difficult to move upward to the drainage area of ​​the outer cylinder 1 under the drive of the water flow, so the sediment accumulates at the bottom of the inner cylinder 2. As the sediment increases, it provides movement resistance to the rotation of the stirring member 5 and the first turbine 6. Since the impact force of water on the first turbine 6 and the second turbine 12 is the same, there will be a rotation difference between the first turbine 6 and the second turbine 12. The second turbine 12 drives the rotating disk 10 to rotate through the connecting column 9, the torsion spring 11 is tightened, and the connecting column 9 and the fixing ring 8 rotate relative to each other. Under the limiting action of the two limiting columns 17, The spline rod 16 rotates with the connecting column 9 and moves upward, and the spline rod 16 and the telescopic end of the first telescopic rod 18 rotate. The telescopic end of the first telescopic rod 18 is squeezed so that the hydraulic oil inside it flows into the cavity of the connecting ring 19 along the oil guide pipe. The hydraulic oil in the connecting ring 19 flows into the two second telescopic rods 20 along the oil guide pipe. The telescopic end of the second telescopic rod 20 contracts and drives the sliding plate 14 to move upward. The sliding plate 14 pulls the tension spring 15 upward. When the tension of the tension spring 15 is greater than the friction damping between the fixed seat 131 and the sliding rod 132, the two tension springs 15 pull the sealing ring 13 upward, and the sealing ring 13 releases the seal on the through hole of the inner cylinder 2.

[0030] Driven by the water flow, the sediment in the inner cylinder 2 is discharged from the through holes thereon and sinks to the bottom of the outer cylinder 1. After the sediment in the inner cylinder 2 is discharged, the resistance encountered by the stirring member 5 and the first turbine 6 during rotation is reduced, and then the first turbine 6 drives the stirring member 5 to return to the initial state, so that the relative positions of the first turbine 6 and the second turbine 12 are restored. At this time, the torsion spring 11 is reset, and the spline rod 16 is reset downward. At the same time, the telescopic end of the first telescopic rod 18 moves downward to allow the hydraulic oil to flow back, and the two second telescopic rods 20 extend downward. The second telescopic rods 20 squeeze the sealing ring 13 downward through the sliding plate 14 and the tension spring 15, so that the lower side of the sealing ring 13 contacts the limit ring below it again, completing the blocking of the through hole of the inner cylinder 2.

[0031] Example 2: Based on Example 1, Figure 3 and Figure 4 , and also includes: a first fixing column 121, fixedly connected to the bottom of the second turbine 12, the first fixing column 121 is coaxially arranged in the water guide shell 3, the diameter of the first fixing column 121 is the same as the diameter of the connecting rod 7, and is used to ensure that the flow area of ​​the middle and lower parts of the water guide shell 3 is the same.

[0032] In the above scheme, the main purpose is to ensure that the first turbine 6 and the second turbine 12 are subjected to the same water flow impact area and speed. The first fixed column 121 is located at the joint of the water guide shell 3 and the water inlet pipe 4, and is used to occupy the water flow area at the lower end of the water guide shell 3, and is used to ensure the flow rate of the water to be treated through the middle and lower parts of the water guide shell 3, so that the relative positions of the first turbine 6 and the second turbine 12 are in a stable state.

[0033] Example 3: Based on Example 2, refer to Figure 7 and Figure 8 , and also includes: a limit rod 21, which has a plurality of limit rods 21, and the plurality of limit rods 21 are respectively slidably connected to adjacent fixed seats 131, and the sliding rod 132 is provided with a limit blind hole, and one end of the limit rod 21 is located in the limit blind hole of the sliding rod 132, and the limit rod 21 is used to limit the sliding rod 132, and an elastic member for resetting is installed between the limit rod 21 and the fixed seat 131, and the other end of the limit rod 21 is fixedly connected to the second fixed column 22; there are a plurality of extrusion plates 23, and the plurality of extrusion plates 23 are respectively fixedly connected to adjacent sliding plates 14, and the extrusion plate 23 is provided with an inclined surface, and the inclined surface is extruded and matched with the second fixed column 22.

[0034] In the above scheme, the main purpose is to slow down the opening time of the sealing ring 13 to the through hole on the inner cylinder 2, avoid frequent movement of the sealing ring 13, and improve the continuity and stability of the operation of the device. There are two limit rods 21, and the two limit rods 21 are respectively slidably connected to the mounting seats of the adjacent fixed seats 131. The limit rod 21 is installed with a limit disk, and an elastic member is installed between the limit disk of the limit rod 21 and the mounting seat on the fixed seat 131. One end of the limit rod 21 is set as a ball head and inserted into the limiting blind hole of the slide rod 132. When the telescopic end of the second telescopic rod 20 drives the sliding plate 14 to move, the limit rod 21 limits the slide rod 132, so that the slide rod 132 and the fixed seat 131 are relatively stationary. In order to reduce the friction between the second fixed column 22 and the extrusion plate 23, a rotating sleeve is provided on the outside of the second fixed column 22.

[0035] Working process: when the second telescopic rod 20 drives the sliding plate 14 to move upward, the tension spring 15 is gradually stretched, but the sliding rod 132 does not slide along the fixed seat 131, and when the inclined surface of the extrusion plate 23 squeezes the second fixed column 22, the second fixed column 22 drives the limiting rod 21 to slide along the mounting seat on the fixed seat 131, and the limiting rod 21 moves out of the limiting blind hole of the sliding rod 132. At this time, the telescopic end of the second telescopic rod 20 has been completely retracted, and then under the tension of the tension spring 15, the tension spring 15 pulls the sealing ring 13 to move upward. There is friction damping between the fixed seat 131 and the sliding rod 132, so that the sealing ring 13 moves slowly upward, avoiding unstable rotation of the stirring member 5 and the first turbine 6, causing the tension spring 15 to be stretched back and forth, thereby causing the sealing ring 13 to slide back and forth up and down, thereby improving the continuity and stability of the device during use.

[0036] After the sediment in the inner cylinder 2 is discharged, the relative positions of the first turbine 6 and the second turbine 12 are restored, the telescopic end of the second telescopic rod 20 moves downward and resets, the sliding plate 14 moves downward and squeezes the tension spring 15, and at the same time the squeezing plate 23 releases the limit on the second fixed column 22, and the tension spring 15 pushes the sealing ring 13 to move downward and reset, until the limiting blind hole of the sliding rod 132 moves to the same height as the limiting rod 21, under the action of the elastic member on the limiting rod 21, the limiting rod 21 slides along the mounting seat above the fixing seat 131, and the limiting rod 21 is again limited with the limiting blind hole of the sliding rod 132.
