Detailed Implementation
[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.
[0037] Reference Figure 1-10A river sewage sludge separation and treatment device includes a device body 100, an arc-shaped filter screen 101 disposed on the side of the device body 100, and multiple sets of filter rollers 200 disposed below the device body 100. It also includes: a rotating mechanism 300 disposed inside the device body 100, which pumps filtered water into the filter rollers 200 when driven by water flow; and a liquid storage pipe 201 disposed at the connection between the filter rollers 200 and the device body 100, which stores the liquid entering the liquid storage pipe 201 and discharges it through the filter rollers 200 when the water flow velocity increases. The device body 100 is rotatably connected to the rotating ring mechanism 300. A sealing groove 302 is provided inside the device body 100, and a sealing slider 305 is provided on the inner side of the sealing groove 302. An arc-shaped protrusion 304 is provided on the outer side of the rotating ring mechanism 300. Multiple sets of drive blades 301 are connected to the inner wall of the rotating ring mechanism 300. A hollow rotating shaft 307 is provided at the intersection of each set of drive blades 301. The rotating ring mechanism 300 has a hollow annular design inside. A drainage groove 306 is provided on the outer wall of the rotating ring mechanism 300. The two ends of the drive blades 301 are connected to the rotating ring mechanism 300 and the hollow rotating shaft 307. The inner cavities of the 7 are connected. The top of the filter roller 200 is connected to the liquid storage tube 201. The inside of the device body 100 is provided with a set of inlet pipes 303 that connect the sealing groove 302 and the inside of the liquid storage tube 201. The inside of the liquid storage tube 201 is provided with an inlet port 202. The top of the inner side of the liquid storage tube 201 is connected to the upper piston slider 203 by a spring. The inside of the liquid storage tube 201 is fixedly installed with a magnetic ring 205 by a support shaft. The top of the magnetic ring 205 is connected to the lower piston slider 204 by a spring. The bottom center of the lower piston slider 204 is provided with a set of through magnetic rings. The limiting rod 207 of the ring 205 has a fixing collar 208 on its outer side wall. The center of the magnetic ring 205 has an elastic collar 209. The inside of the magnetic ring 205 is connected to an impact slider 206 by a spring. The impact slider 206 is connected to the elastic collar 209 by a pull rope. The side wall of the device body 100 is also provided with a flow channel 102. The inside of the flow channel 102 is rotatably connected by a rotating shaft to multiple sets of closely designed flow-blocking blades 103. The center of the flow channel 102 is also designed with a liquid supply head 104 that is rotatably connected to the hollow rotating shaft 307.
[0038] It should be noted that the liquid supply head 104 is connected to and fixed to an external liquid supply device through a set of rigid pipes, thereby maintaining the liquid supply and limiting effect on the liquid supply head 104. The external liquid supply device is fixedly installed above the device body 100.
[0039] It should be noted that the filter roller 200 is designed to be inclined and hollow inside. Spray holes are opened on the side of the filter roller 200 facing the direction of water flow.
[0040] Reference Figure 4The arc-shaped protrusion 304 extends to the farthest point outside the rotating mechanism 300 and fits against the inner wall of the sealing groove 302.
[0041] The arc-shaped protrusion 304 extends to the furthest point outside the rotating ring mechanism 300, and the distance between the arc-shaped protrusion 304 extending to the nearest point outside the rotating ring mechanism 300 is arc-shaped. The distance between the arc-shaped protrusion 304 and the nearest point outside the rotating ring mechanism 300 is 0, meaning it has the same outer contour as the rotating ring mechanism 300. When the rotating ring mechanism 300 rotates, the arc-shaped protrusion 304 rotates towards the sealing slider 305 inside the sealing groove 302. This is because the arc-shaped protrusion 304 and the inner wall of the sealing groove 302... As the curved protrusion 304 rotates, it pushes the sealing slider 305 toward the inside of the device body 100. This causes the space between the curved protrusion 304, the sealing groove 302, and the sealing slider 305 to become smaller and smaller as the curved protrusion 304 rotates. This allows the curved protrusion 304 to discharge the water flow in the gap between the curved protrusion 304 and the sealing groove 302 into the inside of the liquid inlet pipe 303 under pressure.
[0042] Furthermore, a set of channels is provided inside the drive blade 301 to connect the interior of the hollow rotating shaft 307 and the interior of the rotating ring mechanism 300, and a set of channels is provided inside the drive blade 301 to connect the exterior of the drive blade 301 with the interior of the rotating ring mechanism 300.
[0043] It should be noted that the liquid supply head 104 has a liquid supply hole on its surface. The liquid supply head 104 is kept in a fixed state by a rigid tube. When the hollow rotating shaft 307 rotates, the oxidant liquid used to purify organic matter in the river sludge inside the liquid supply head 104 can flow into the drive blade 301 through the flow hole of the hollow rotating shaft 307, and then flow into the rotating ring mechanism 300 through the internal channel of the drive blade 301. It then enters the sealing groove 302 and is pumped into the storage pipe 201. The rectangular channel connecting the surface of the drive blade 301 to the outside of the drive blade 301 is also equipped with a filter screen to prevent impurities from entering.
[0044] It should be noted that the drain trough 306, the inlet pipe 303, and the drive blade 301 are all equipped with one-way valves. Specifically, the drain trough 306 has a one-way valve with the flow direction from the inside of the rotating mechanism 300 to the inside of the sealing groove 302. After the arc-shaped protrusion 304 rotates past the sealing slider 305, the sealing slider 305 rebounds and comes into contact with the outer wall of the rotating mechanism 300. As the arc-shaped protrusion 304 moves away from the sealing slider 305, the pressure inside the cavity formed by the sealing groove 302, the sealing slider 305, and the outer wall of the rotating mechanism 300 decreases. Liquid inside the rotating mechanism 300 can then be drawn into the sealing groove 302 through the drain trough 306 for subsequent circulation pumping into the inlet pipe 303. The inlet pipe 303 has a flow direction... The sealing groove 302 has a one-way valve facing the inside of the liquid storage pipe 201, which allows liquid to pass through in one direction and prevents liquid backflow. The inside of the drive blade 301 is equipped with two sets of one-way valves. One set flows from the inside of the hollow rotating shaft 307 to the inside of the rotating ring mechanism 300, which can prevent the medicine from flowing back. Only when the drive blade 301 rotates and generates centrifugal force will the medicine inside the drive blade 301 be discharged into the rotating ring mechanism 300 under the action of centrifugal force, which can prevent liquid backflow. At the same time, when the drive blade 301 is stationary or rotating slowly, the centrifugal force on the medicine is small, so it will not be discharged, avoiding waste of medicine. The other set flows from the inside of the drive blade 301 to the inside of the sealing groove 302, which can prevent the medicine and liquid mixture inside the rotating ring mechanism 300 from flowing back.
[0045] Reference Figure 8 The inlet 202 is located between the upper piston slider 203 and the lower piston slider 204.
[0046] It should be noted that when water enters through the inlet 202, the water flow can simultaneously apply pressure to the upper piston slider 203 and the lower piston slider 204 on both sides.
[0047] It should be noted that the upper piston slider 203, the lower piston slider 204, and the magnetic ring 205 are constructed of magnetic materials that cooperate with each other.
[0048] Specifically, the upper piston slider 203 and the lower piston slider 204 attract each other, and the lower piston slider 204 and the magnetic ring 205 attract each other. As the rotational speed of the drive blade 301 increases, when the liquid pumped into the storage pipe 201 through the inlet 202 is at a relatively high speed, a portion of the entering liquid is discharged through the through-hole of the lower piston slider 204. When the speed of the liquid entering the storage pipe 201 is greater than the discharge speed through the through-hole of the lower piston slider 204, the liquid accumulates between the upper piston slider 203 and the lower piston slider 204, pushing the upper piston slider 203 and the lower piston slider 204 in directions away from each other. It should be noted that, with the lower piston slider 204... The elastic coefficient of spring 2 connected to 04 is greater than that of spring 1 connected to the upper piston slider 203. Liquid accumulates between the upper piston slider 203 and the lower piston slider 204, gradually increasing the gap between them until the lower piston slider 204 is pushed close to the magnetic ring 205. At this point, the lower piston slider 204 is attracted to the magnetic ring 205 under the action of liquid pressure and magnetic force. Simultaneously, the lower piston slider 204 shifts to a region with a larger diameter inside the liquid storage tube 201, allowing the liquid accumulated between the upper piston slider 203 and the lower piston slider 204 to pass through the surface of the lower piston slider 204. The sludge discharged through the through-hole and the side of the lower piston slider 204 enters the interior of the filter roller 200 and is discharged through the spray holes on the surface of the filter roller 200. This backwashes the sludge accumulated on the surface of the filter roller 200. Through the combined action of water flow and chemical solution, the decomposition of sludge and degradation of organic matter are accelerated. Functional groups such as hydroxyl and carboxyl groups in the organic polymers of the sludge are oxidized, producing low-activity oxides. This also promotes sludge granulation and dissolution, thereby reducing the viscosity of the polymers in the sludge. This allows for backwashing and oxidation treatment of the sludge layer that is clogged in contact with the filter roller 200. The sludge after washing and oxidation can then... The sludge settles by sliding down the inclined surface of the filter roller 200, reducing clogging. When the subsequent sludge layer continues to adhere to the filter roller 200 and clogs under the action of water flow, it can be further sprayed and rinsed through the filter roller 200 for oxidation treatment. This allows for layered rinsing and oxidation treatment of the filtered sludge, reducing sludge stickiness and adhesion, improving sludge decomposition and sedimentation, reducing clogging by sticky sludge, and making the sludge less sticky for subsequent treatment. In addition, when treating sludge separately after wastewater treatment, it can reduce the problem of sludge adhering to the surface of the filter roller 200, which would make sludge collection difficult and leave residue, thus improving the efficiency of subsequent sludge collection and treatment.
[0049] Furthermore, the inner diameter of the liquid storage tube 201 varies at different locations, thus enabling closure and connection through the cooperation between it and the lower piston slider 204.
[0050] Reference Figure 9 The surface of the lower piston slider 204 has a ring of holes distributed around its axis.
[0051] It should be noted that the through holes can ensure normal liquid flow. When the blockage is severe, the continuous flow of liquid can prevent the grooves on the surface of the filter roller 200 from being blocked by sludge, and facilitate subsequent liquid storage and rinsing.
[0052] Reference Figure 10 The elastic collar 209 is formed by multiple sets of arc-shaped sliders connected by elastic ropes. The inner side of the elastic collar 209 and the fixed collar 208 are designed with mutually cooperating chamfers.
[0053] Specifically, during the process of the lower piston slider 204 displacing to the magnetic ring 205 for adsorption, when the limiting rod 207 and the fixing collar 208 pass through the center of the magnetic ring 205, the fixing collar 208 can push the elastic collar 209 to move at the center of the magnetic ring 205. The elastic collar 209 and the center of the magnetic ring 205 remain in close contact until the fixing collar 208 passes through the central area of the magnetic ring 205. During this process, the movement of the elastic collar 209 can be achieved by pulling the rope to impact the slider 206, while the spring is compressed. After the fixing collar 208 passes through the central area of the magnetic ring 205, the elastic collar 209, having lost the pressure of the inner wall of the magnetic ring 205, increases in diameter due to the expansion and contraction of the elastic rope connecting the elastic collars 209. The elastic collar 209 can then return to its original position after passing through the chamfered angle of the fixing collar 208. During the resetting process... In the middle, under the elastic reset action of spring three, the impact slider 206 can be pushed to reset, impacting the inner wall of the liquid storage tube 201, causing the liquid storage tube 201 and the filter roller 200 to vibrate. This achieves the simultaneous reverse rinsing of the sludge attached to the outside of the filter roller 200 by the downward movement of the lower piston slider 204, and the vibration force generated by the impact slider 206 on the filter roller 200. Since the sludge activity and viscosity are reduced after being rinsed and oxidized by the filter roller 200, the overall granulation effect is higher. Vibration can accelerate the sedimentation of the treated sludge, causing it to slide to the bottom, so that the subsequent sludge layer is close to the filter roller 200. Through the subsequent rinsing and vibration of the filter roller 200, the detachment and sedimentation of the treated sludge from the filter roller 200 can be accelerated, improving the effect of the stratified rinsing treatment of the filtered sludge layer.
[0054] It should be noted that after the liquid accumulated between the upper piston slider 203 and the lower piston slider 204 is discharged, the upper piston slider 203 resets and moves closer to the lower piston slider 204. As the upper piston slider 203 moves closer, the balance between the magnetic attraction force of the magnetic ring 205 and the elastic force of the spring 2 on the piston slider 204 under the pressure of the accumulated liquid is broken. Under the action of the elastic force of the spring 2 and the magnetic force of the upper piston slider 203, the lower piston slider 204 overcomes the attraction force of the magnetic ring 205 and resets, thus starting the next round of liquid storage cycle. During the reset process of the lower piston slider 204, the limiting rod 207 drives the fixed collar 208 to reset, which can drive the elastic collar 209 to continue to impact the impact slider 206 to complete a set of energy storage impacts, so that the filter roller 200 can continue to be impacted after rinsing and oxidation treatment, thereby increasing the sludge removal and sedimentation speed of the filter roller 200 with reduced surface viscosity.
[0055] Reference Figure 6 The flow-blocking blade 103 is rotatably connected to the flow channel 102 via a set of support shafts. The shaft inside the flow-blocking blade 103 that is rotatably connected to the flow channel 102 is eccentrically designed, and the outer wall of the flow-blocking blade 103 is designed with a torsion spring for resetting at the connection part with the flow channel 102.
[0056] It should be noted that, through the eccentric design, when the water flow impact force on the flow-blocking blade 103 increases, multiple sets of flow-blocking blades 103 can rotate simultaneously to the same side to supply water flow, improving the smoothness of water flow and reducing turbulence. At the same time, through the torsion spring design, when the water flow velocity and impact force inside the flow channel 102 are small, the water flow can flow through the gaps between the flow-blocking blades 103 without pushing the flow-blocking blades 103 to rotate. The water flow velocity inside the flow channel 102 is low. Only when the water flow impact force increases will the flow-blocking blades 103 rotate and deflect, increasing the flow velocity inside the flow channel 102. This increases the water flow velocity inside the flow channel 102, thereby making the drive blade 301 rotate stably under the action of the water flow driving force.
[0057] The working principle of this river sewage sludge separation and treatment device:
[0058] The wastewater and sludge mixture to be filtered is directed into a set of separation tanks, and filtered by flowing through the device body 100 and the filter roller 200. When there is no blockage or the blockage is low, the flow velocity and impact force of the water flowing through the rotating mechanism 300 are small, the rotating mechanism 300 rotates at a low speed or does not rotate, and the device does not start to store liquid.
[0059] When the amount of sludge is large and the organic matter in the river is highly viscous, causing blockage of the gaps between the filter rollers 200, the lower part of the filter rollers 200 is blocked. Water flows along the slope of the filter rollers 200 and the blocked sludge, concentrating the flow at the top. This increases the impact force of the water flowing through the flow channel 102, driving the flow-blocking blades 103 to rotate. This increases the flow velocity inside the flow channel 102, causing the drive blades 301 to rotate stably under the driving force of the water flow. As the drive blades 301 rotate, centrifugal force draws the filtered water and chemical solution into the rotating mechanism 300. Simultaneously, the rotation of the arc-shaped protrusion 304 inside the sealing groove 302 pumps the mixed liquid into the storage pipe 201 through the inlet pipe 303, while simultaneously... The drain tank 306 draws the liquid inside the rotating mechanism 300 into the sealing tank 302 for continuous circulation. The liquid pumped into the storage pipe 201 pushes the upper piston slider 203 and the lower piston slider 204 away from each other to achieve liquid storage. When the lower piston slider 204 moves close to the magnetic ring 205 and is attracted, the stored liquid can be accelerated by the reset of the upper piston slider 203 and sprayed out from the nozzle on the surface of the filter roller 200 to achieve reverse flushing and oxidation treatment of the sludge layer that is in contact with and blocked by the filter roller 200. The sludge after flushing and oxidation can slide down the inclined surface of the filter roller 200 to settle and reduce blockage. When the sludge layer continues to be close to and blockage the filter roller 200 under the action of water flow, it can be flushed and oxidized by spraying through the filter roller 200. This can achieve layered flushing and oxidation treatment of the filtered sludge.
[0060] During the movement of the lower piston slider 204, the movement and reset of the elastic collar 209 drive the impact slider 206 to complete one energy storage and impact on the liquid storage pipe 201. The impact can generate a corresponding vibration force on the filter roller 200, which can accelerate the sedimentation of the sludge after washing and oxidation treatment to the bottom through vibration, so that the subsequent sludge layer is close to the filter roller 200, which can accelerate the separation and sedimentation of the treated sludge from the filter roller 200, and improve the effect of the layered washing treatment of the filtered sludge layer.
[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
