Description

Technical Field

[0001] The present invention relates to the technical field of concentrated liquid filtration, and particularly to a filter ramp side water inlet assembly and method for diluting the inlet water concentration by using the swirl force of water flow. Background Art

[0002] A hydrocyclone is a common separation and classification device. When a two-phase mixed liquid to be separated enters the hydrocyclone tangentially from the periphery at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the particle size difference between coarse particles and fine particles, the centrifugal force, centripetal buoyancy force, fluid drag force, etc. acting on them are different. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the underflow port of the hydrocyclone, while most of the fine particles are discharged through the overflow pipe, so as to achieve the purpose of separation and classification.

[0003] The swirl velocity formed by the lateral water inlet of the traditional hydrocyclone often obtains a fixed tangential velocity due to the self-structure design of the hydrocyclone, and it is difficult to dynamically adjust the separation efficiency according to the inlet water pollutant concentration. High-concentration sewage is prone to incomplete separation due to insufficient residence time, while low-concentration sewage causes energy consumption waste due to over-treatment; in addition, the sensor for detecting the water flow concentration is easily contaminated when in long-term contact with sewage, resulting in inaccurate monitoring. Therefore, there is an urgent need for an intelligent filtration system that can sense the water quality in real time, dynamically adjust the swirl intensity and has the self-cleaning ability. Summary of the Invention

[0004] In order to overcome the defects in the prior art, the purpose of the present invention is to provide a filter ramp side water inlet assembly and method for diluting the inlet water concentration by using the swirl force of water flow, so as to solve the problems proposed in the above background art.

[0005] To achieve the above purpose, on the one hand, the present invention provides a filter ramp side water inlet assembly for diluting the inlet water concentration by using the swirl force of water flow, including a water inlet cylinder and a water inlet groove externally connected and embedded on the side wall. A plurality of filter cylinders in the shape of an inverted conical cylinder are fixedly connected below the bottom end of the water inlet cylinder, and the plurality of filter cylinders are fixedly connected end to end. An upper discharge pipe is embedded at the center of the top of the water inlet cylinder; a speed regulating valve group is arranged inside the water inlet cylinder for adjusting the speed of the water flow rotation formed in the water inlet cylinder, and a monitoring and control group is arranged in the area above the water inlet groove for monitoring the concentration of the introduced water and feeding back to control the speed regulating valve group to adjust its posture;

[0006] The speed regulating valve group includes a spiral valve plate, an adjusting block for suspending the side wall at the bottom end of the valve plate, and a servo motor for driving the adjusting block to lift and lower; the speed of the water flow rotation formed in the water inlet cylinder is adjusted by adjusting the spiral pitch of the valve plate to adapt to the treatment of high and low concentration water;

[0007] The monitoring and control group includes a turbidity sensor extending into the top of the water diversion tank, a water passing box sleeved with the turbidity sensor, and a lifting group arranged on the top of the water passing box, which is used to lift the turbidity sensor into the water passing box and be flushed by the tap water introduced to remove attachments.

[0008] As a further improvement of this technical solution, the outer diameter of the valve plate is adapted to the inner diameter of the water inlet cylinder, the inner diameter of the valve plate is larger than the inner diameter of the upper row pipe, the upper end of the valve plate is placed in the middle of the water outlet of the water diversion tank and is fixedly connected to the inner side wall of the water inlet cylinder.

[0009] As a further improvement of this technical solution, the adjusting block is a T-shaped block and transmission rods are connected to the bottom surfaces of both sides thereof. A lifting rod that slidably contacts the inner side wall of the water inlet cylinder is provided at the bottom end of the transmission rod. A bayonet is formed on the outer side of the valve plate and below the adjusting block. The width of the bayonet is larger than the width of the lifting rod and is clamped with the lifting rod. Clamping blocks are arranged at intervals up and down at the bottom end of the lifting rod towards the side wall of the valve plate, and a pair of clamping blocks are clamped with the upper and lower surfaces of the bayonet.

[0010] As a further improvement of this technical solution, a cam is connected to the output shaft end of the servo motor, and the cam slidably contacts the bottom surface of the vertical end of the adjusting block.

[0011] As a further improvement of this technical solution, the water passing box has a frustum structure and water passing nozzles are communicated and arranged on both sides of its bottom. The upper end of the turbidity sensor is inserted and slid in the upper port of the water passing box. A jack for inserting the turbidity sensor is opened at the center of the bottom of the water passing box. Water pipes are sleeved on both side ends of the bottom of the water passing box for introducing and discharging tap water; the lifting group includes a lifting frame sleeved on the top of the turbidity sensor, two transmission tooth columns meshing and driving with the outside of the lifting frame, and a micro motor for driving the two transmission tooth columns to rotate in opposite directions.

[0012] As a further improvement of this technical solution, closing rods for closing the jack are symmetrically arranged inside the water passing box. The top ends of the two closing rods are rotatably connected with a collar, and the collar is slidably sleeved with the turbidity sensor. A sealing block is arranged at the bottom end of the closing rod and biased towards one side. The inscribed circle size of the two sealing blocks in the closed state is larger than the size of the jack.

[0013] As a further improvement of this technical solution, a folding elastic piece is fixedly connected to the side wall of the top of the closing rod and above the sealing block. A pair of limiting shafts are embedded on the straight side of the water passing box and at the top of the slope. The distance between the pair of limiting shafts is equal to the distance between the pair of closing rods in the parallel state.

[0014] As a further improvement of the technical solution, a linkage bar in an inverted T shape is symmetrically attached to the side surface of the turbidity sensor. The distance between the horizontal section of the linkage bar and the bottom end of the turbidity sensor is less than the length of the closing rod. Guide grooves penetrating up and down are symmetrically formed inside the collar. The vertical sections of the linkage bar are slidably inserted into the guide grooves. A brush roller is suspended on the top surface of the sealing block. The axial direction of the brush roller is perpendicular to the orientation of the water passing nozzle.

[0015] As a further improvement of the technical solution, a water diversion pipe is fixedly connected to the outer port of the water diversion tank. A lower discharge pipe is connected to the bottom end of the lowermost filter cylinder.

[0016] On the other hand, the present invention also provides a filtering method for diluting the concentration of influent water by using the swirling force of water flow. Using the above-mentioned filter ramp side water inlet assembly for diluting the concentration of influent water by using the swirling force of water flow, it includes the following steps:

[0017] S1. After the sewage passes through the water diversion tank and enters the water inlet cylinder, it will be first diverted by the valve plate and then form a vortex along with the spiral channel space of the water inlet cylinder.

[0018] S2. At the same time, the concentration value of the sewage is monitored by the turbidity sensor to determine whether it is high-concentration water or low-concentration water, and then feedback is provided to control the servo motor to start, and the lifting rod is controlled to adjust the spiral pitch of the valve plate to form different tangential velocities of the vortex. The specific situations are as follows:

[0019] S21. When the spiral pitch of the valve plate tends to decrease, the water flow resistance increases, the tangential speed of the vortex decreases, which is suitable for the scenario of prolonging the separation time for high-concentration water.

[0020] S22. When the spiral pitch of the valve plate tends to increase, the water flow resistance decreases, the tangential speed of the vortex increases, which is suitable for the scenario of quickly treating low-concentration water.

[0021] S3. After the vortex water flow in the water inlet cylinder enters several filter cylinders, a centrifugal swirling state is formed. The mixed particles in the water are then separated under the action of centrifugal force. The particles with a large density are concentrated in the inner wall area of the filter cylinder to form an outer vortex and move downward along the axis of the filter cylinder to be discharged. The particles with a small density are concentrated in the central axis area of the filter cylinder to form an inner vortex and move upward along its axis to be discharged.

[0022] S4. Every once in a while, the turbidity sensor is controlled to retract into the water passing box by starting the micro motor. At the same time, a pair of closing rods are lifted and closed together, and a pair of sealing blocks are used to block the jacks.

[0023] S5. Then, tap water is turned on through the bottom of the water passing box to wash the bottom terminals of the turbidity sensor, and then the turbidity sensor is reset in the reverse operation to continue monitoring the water flow concentration.

[0024] Compared with the prior art, the beneficial effects of the present invention:

[0025] 1. The filter slope side water inlet component and method that utilizes the vortex of water flow to dilute the inlet water concentration can adjust the spiral spacing of the valve plates in real time through real-time monitoring by a speed regulating valve group and a monitoring and control group linked by a spiral spring steel valve plate and a servo motor. Under high-concentration sewage conditions, the valve plate spacing is reduced to increase water flow resistance, reduce the tangential velocity of the vortex, and extend the separation time. Under low-concentration sewage conditions, the valve plate spacing is expanded to reduce resistance, accelerate the tangential velocity of the vortex, and improve treatment efficiency. The effect of dynamically matching separation time and water quality requirements is achieved, avoiding energy waste and incomplete treatment.

[0026] 2. The filter slope side water inlet assembly and method that utilizes the swirling force of water flow to dilute the concentration of inlet water, wherein a turbidity sensor is housed in a water-passing box and tap water is introduced for flushing. The turbidity sensor is controlled to retreat into the water-passing box by starting a micro-motor at regular intervals, and a pair of closing rods are raised and closed to block the jack. The water flow introduced into the water-passing nozzle flushes the rotating brush roller and sweeps the attachments at the bottom of the turbidity sensor, thereby improving the cleaning efficiency.

[0046] Please refer to Figures 1 - 12 As shown, the present invention provides a filter ramp side water inlet assembly that utilizes the swirling force of water flow to dilute the concentration of the influent, including a water inlet cylinder 100 and a water diversion trough 110 embedded and communicated on the outer side wall. A water diversion pipe 111 is fixedly connected to the outer port of the water diversion trough 110 for connecting to a sewage pipe to introduce sewage into the water inlet cylinder 100; a number of filter cylinders 120 in the shape of an inverted conical cylinder are fixedly connected below the bottom end of the water inlet cylinder 100. The number of filter cylinders 120 are fixedly connected end to end. The bottom end of the lowermost filter cylinder 120 is connected to a lower discharge pipe 130, and an upper discharge pipe 140 is embedded at the center of the top of the water inlet cylinder 100; a speed control valve group 200 is arranged inside the water inlet cylinder 100 for adjusting the speed of the water flow rotation formed in the water inlet cylinder 100. A monitoring and control group 300 is arranged in the area above the water diversion trough 110 for monitoring the concentration of the diverted water and feeding back to control the attitude adjustment of the speed control valve group 200, that is, distinguishing and controlling the water flow rotation speed according to the concentration of the sewage, so as to increase the rotation separation time for high-concentration sewage and quickly separate and treat low-concentration sewage, thereby reasonably allocating the filtration time and controlling the filtration situation.

[0047] Specifically, as Figures 4 - 6 shown, the speed control valve group 200 includes a valve plate 210 in a spiral shape, an adjustment block 220 for suspending the bottom side wall of the valve plate 210, and a servo motor 230 for driving the adjustment block 220 to move up and down; the valve plate 210 is made of spring steel into a spiral sheet, so that it can be deformed to adjust the spiral pitch, forming water flow spiral channels at different angles, and adjusting the swirling speed of the water; by adjusting the spiral pitch of the valve plate 210, the speed of the water flow rotation formed in the water inlet cylinder 100 is adjusted to adapt to the treatment of high and low concentration water.

[0048] The outer diameter of the valve plate 210 is adapted to the inner diameter of the water inlet cylinder 100, so that the valve plate 210 and the inner wall of the water inlet cylinder 100 are separated into water flow channels to form a swirl; the inner diameter of the valve plate 210 is larger than the inner diameter of the upper discharge pipe 140 to avoid blocking the upward diversion movement; the upper end of the valve plate 210 is placed in the middle of the water outlet of the water diversion trough 110 and is fixedly connected to the inner side wall of the water inlet cylinder 100; the output shaft end of the servo motor 230 is connected with a cam 231, and the cam 231 is in sliding contact with the bottom surface of the vertical end of the adjustment block 220.

[0049] Further, the adjusting block 220 is in the shape of a T-shaped block, and transmission rods 221 are connected to the bottom surfaces of both sides thereof. A lifting rod 222 that is in sliding contact with the inner side wall of the water inlet cylinder 100 is provided at the bottom end of the transmission rod 221, which minimizes the influence on the swirling speed. A bayonet 211 is formed on the outer side of the valve plate 210 and below the adjusting block 220. The width of the bayonet 211 is greater than the width of the lifting rod 222 and is clamped with the lifting rod 222. Clamping blocks 223 are arranged at intervals up and down at the bottom end of the lifting rod 222 facing the side wall of the valve plate 210. A pair of clamping blocks 223 are clamped with the upper and lower surfaces of the bayonet 211. By lifting the lifting rod 222, the lower end of the valve plate 210 rises, and the valve plate 210 contracts under its own elastic force and synchronously reduces the spiral pitch to form a swirling channel with different tangential angles.

[0050] Specifically, as Figures 7 - 12 shown, the monitoring and control group 300 includes a turbidity sensor 310 extending into the top of the water diversion tank 110, a water passing box 320 sleeved with the turbidity sensor 310, and a lifting group 330 arranged on the top of the water passing box 320, which is used to lift the turbidity sensor 310 to retract into the water passing box 320 for flushing the attached substances by the introduced tap water; since the bottom terminal of the turbidity sensor 310 is placed in the sewage, attached substances will inevitably accumulate, which will affect the accuracy of the sensor. Therefore, the lifting group 330 is set to lift the turbidity sensor 310 to retract into the water passing box 320 for flushing at intervals to ensure its accurate monitoring work.

[0051] The turbidity sensor 310 is a laser scattering turbidity sensor, such as the Hach TU5 series, with a detection range of 0 - 4000 NTU and an accuracy of ±2%. It detects the scattered light intensity of suspended particles by passing 905 nm laser through the water body and outputs the turbidity value in real time. In addition, an ultrasonic suspended solid concentration sensor, such as the Sensorex SC450, can be additionally installed. It measures the suspended solid concentration by using the principle of acoustic wave attenuation to compensate for the failure risk of the optical sensor under high turbidity.

[0052] The water passing box 320 is in a frustum structure, and water passing nozzles 321 are communicated and arranged on both sides of the bottom thereof. The upper end of the turbidity sensor 310 is inserted and slid into the upper port of the water passing box 320. A jack 323 for inserting the turbidity sensor 310 is opened at the center of the bottom of the water passing box 320. Silicone rings are sleeved on the inner sides of the upper port and the jack 323 of the water passing box 320 to play a sealing role; water pipes are sleeved on both side ends of the bottom of the water passing box 320 for introducing and discharging tap water.

[0053] Specifically, the lifting group 330 includes a lifting frame 331 sleeved on the top of the turbidity sensor 310, two transmission tooth columns 332 meshing and driving on the outer side of the lifting frame 331, and a micro motor 333 for driving the two transmission tooth columns 332 to rotate relatively in reverse; the lifting frame 331 is formed by a pair of parallel and vertically arranged racks 3311, and a ring sleeved on the top of the turbidity sensor 310 is welded at the bottom ends of the pair of racks 3311 to form an integral body. The transmission tooth columns 332 are meshed with the racks 3311, and transmission gears 334 are arranged between the ends of the two transmission tooth columns 332. A plurality of blades 3321 meshed with the transmission gears 334 are arranged on the outer side of the ends of the transmission tooth columns 332. The micro motor 333 is fixed to the top side wall of the water passing box 320 by bolts, and the micro motor 333 is connected to the transmission gear 334 through belt drive, so as to drive the two transmission tooth columns 332 to rotate relatively in reverse, and drive the integral lifting of the lifting frame 331 and the turbidity sensor 310 to adjust the position.

[0054] As Figure 7 and Figure 10 shown, a frame for supporting the transmission tooth column 332 and the transmission gear 334 is bonded to the top end of the water passing box 320.

[0055] Furthermore, in order to prevent the sewage flowing into the water diversion tank 110 from seeping into the water passing box 320 and affecting the cleaning progress of the turbidity sensor 310, closing rods 340 for closing the jacks 323 are symmetrically arranged inside the water passing box 320. The top ends of the two closing rods 340 are rotatably connected with a collar 350. A clamping groove 351 is symmetrically opened along the radial direction on the outer side of the collar 350, and the upper ends of the closing rods 340 are rotatably connected with the clamping groove 351 through pins; the collar 350 is slidably sleeved on the turbidity sensor 310. A sealing block 341 is arranged on one side of the bottom end of the closing rod 340 in a biased manner. The inscribed circle size of the two sealing blocks 341 in the closed state is larger than the size of the jack 323, so as to cover the jack 323 and prevent sewage from seeping in.

[0056] A folding elastic sheet 343 is fixedly connected to the top side wall of the closing rod 340 and above the sealing block 341. It is made of spring steel into a V-shaped sheet. A pair of limiting shafts 322 are embedded at the straight side of the water passing box 320 and at the top of the slope. The distance between the pair of limiting shafts 322 is equal to the distance between the pair of closing rods 340 in the parallel state; a pair of inverted T-shaped linkage bars 311 are symmetrically attached to the side surface of the turbidity sensor 310. When the turbidity sensor 310 retracts into the water passing box 320, the linkage bar 311 drives the collar 350 to rise, so that the upper sections of the pair of closing rods 340 are clamped and closed by the pair of limiting shafts 322. When the pair of sealing blocks 341 cover the jack 323, the folding elastic sheet 343 is compressed to store elastic energy and rebounds to expand and reset the closing rod 340 without limitation, so that the turbidity sensor 310 can extend out of the jack 323 to continue monitoring work.

[0057] It should be noted that the distance between the horizontal section of the linkage bar 311 and the bottom end of the turbidity sensor 310 is less than the length of the closing rod 340. After the bottom end of the turbidity sensor 310 completely rises above the sealing block 341 for a certain distance, the linkage bar 311 drives the collar 350 to lift a pair of closing rods 340 upward, and then the pair of closing rods 340 are slidably clamped together by a pair of limiting shafts 322 to form a closed jack 323; symmetrically arranged on the inner side of the collar 350 are through guide grooves 352 in the up and down directions, and the vertical section of the linkage bar 311 is slidably inserted into the guide grooves 352 to prevent a pair of closing rods 340 from deflecting; a brush roller 342 is suspended on the top surface of the sealing block 341, and the axial direction of the brush roller 342 is perpendicular to the orientation of the water inlet nozzle 321. The brush roller 342 is rotated by the water flow passing through the water inlet nozzle 321 to sweep the attachments at the bottom end of the turbidity sensor 310, thereby improving the cleaning efficiency.

[0058] The present invention also provides a filtering method for diluting the concentration of influent water by using the swirling force of water flow. Using the filter ramp side water inlet assembly for diluting the concentration of influent water by using the swirling force of water flow as described above, the method includes the following steps:

[0059] S1. After the sewage enters the water inlet cylinder 100 through the water inlet trough 110, it will be first split by the valve plate 210 and then form a vortex along the spiral channel space between it and the water inlet cylinder 100.

[0060] S2. At the same time, the turbidity sensor 310 monitors the concentration value of the sewage to determine whether it is high-concentration water or low-concentration water, and then feeds back and controls the servo motor 230 to start, and controls the lifting rod 222 to adjust the spiral pitch of the valve plate 210 to form different tangential velocities of the vortex. The specific situations are as follows:

[0061] S21. When the spiral pitch of the valve plate 210 tends to decrease, the water flow resistance increases, and the tangential velocity of the vortex decreases, which is suitable for the scenario of prolonging the separation time for high-concentration water;

[0062] S22. When the spiral pitch of the valve plate 210 tends to increase, the water flow resistance decreases, and the tangential velocity of the vortex increases, which is suitable for the scenario of quickly treating low-concentration water;

[0063] S3. After the vortex water flow in the water inlet cylinder 100 enters into a plurality of filter cylinders 120, a centrifugal swirling state is formed. The mixed particles in the water are then split under the action of centrifugal force. The particles with a large density are concentrated in the inner wall area of the filter cylinder 120 to form an outer vortex and move downward along the axis of the filter cylinder 120 and are discharged, that is, discharged from the lower discharge pipe 130. The particles with a small density are concentrated in the central axis area of the filter cylinder 120 to form an inner vortex and move upward along its axis and are discharged, that is, discharged from the upper discharge pipe 140, thereby achieving the separation and filtration effect;

[0064] S4. At regular intervals, start the micro-motor 333 to control the turbidity sensor 310 to retract into the water passing box 320. At the same time, lift a pair of closing rods 340 together to close, and use a pair of sealing blocks 341 to block the jack 323.

[0065] S5. Then turn on the tap water to pass through the bottom of the water passing box 320 to wash the bottom terminal of the turbidity sensor 310, and then operate in reverse to reset the turbidity sensor 310 to continue monitoring the water flow concentration.
