Description

Technical Field

[0001] The present invention belongs to the technical field of dynamic membrane filtration, and in particular relates to a self-cleaning dynamic membrane separation and environmentally friendly pesticide filtration integrated machine. Background Art

[0002] Cake-layer dynamic membranes: During the filtration process, suspended particles, colloids, or solutes in the feed solution spontaneously deposit on the surface of a large-pore support to form a temporary cake layer. This cake layer replaces traditional separation membranes to achieve the interception function. Its "dynamic" characteristics are reflected in the deposition-shedding equilibrium state of the cake layer, rather than the movement of the membrane components, which distinguishes it from actively moving dynamic membranes.

[0003] Conventional membranes have a core deficiency in pesticide filtration and separation: Although conventional membrane separation technologies (such as reverse osmosis (RO) and nanofiltration (NF)) have high precision, they suffer from severe membrane fouling, high energy consumption, and pesticide components that easily lead to membrane degradation, resulting in high costs.

[0004] Technical adaptability of cake-layer dynamic membranes: Dynamic membranes use the cake layer (composed of deposited pollutant particles and colloids) that spontaneously forms during operation as the primary filtration barrier, effectively reducing direct contamination of the membrane itself and extending its life. Furthermore, by controlling operating conditions (such as flow rate and aeration intensity), the cake layer structure can be adjusted to meet the separation requirements of pollutants of different particle sizes in pesticide wastewater (from suspended solids to colloids and large organic molecules).

[0005] Traditional exposure and washing process: During the filtration process, pollutants such as suspended particles, colloids, and organic matter are deposited on the membrane surface, forming a porous or dense filter cake layer, which leads to a decrease in membrane flux and an increase in filtration resistance. At this time, air is blown into the bottom of the membrane assembly through an aeration device (such as an aeration head or perforated tube), forming a large number of bubbles. The bubbles rise rapidly under the action of buoyancy, driving the water flow upward. As the bubbles rise, the velocity gradient of the surrounding water increases, forming strong turbulence on the membrane surface. Afterwards, the shear force generated by the turbulence acts directly on the filter cake layer, loosening its structure. When the bubbles come into contact with the membrane surface, they produce mechanical impact on the filter cake layer, stripping off some particulate pollutants. When the bubbles burst, the microjets generated instantly further flush the membrane pores and remove the blockage.

[0006] During specific implementation, since the orifices of fixed aeration devices (such as perforated pipes and aeration plates) are usually evenly spaced, the orifices close to the air source inlet have higher pressure and greater airflow velocity, while the orifices at the far end experience pressure attenuation due to resistance along the way (pipeline friction, local resistance), resulting in a reduced airflow rate and an initial distribution of "strong near the end and weak far the end", further exacerbating regional aeration effect differences.

[0007] In addition, in an asymmetric flow field, the rising trajectory of bubbles will be offset, resulting in shear differences between bubbles and filter cake layers in different areas, and the fluid shear force on the dynamic membrane surface is positively correlated with the rising speed of bubbles; there are differences between bubbles in the central area of ​​the component and the edge area, which in turn leads to different thicknesses in different areas of the filter cake layer.

[0036] The alternating high-efficiency gradient cleaning method for the filter cake layer on the surface of the dynamic membrane is carried out using the above-mentioned self-cleaning dynamic membrane separation environmentally friendly pesticide filter integrated machine to implement the cleaning process. The specific steps are as follows:

[0037] S1: First, the vertical beam provides a stable movement guide to the horizontal frame. During this process, the exposure and washing chamber is controlled by the U-shaped frame, and the water distribution plate drives the ejector pin to generate relative shear movement with the filter cake layer on the surface of the dynamic membrane plate;

[0038] Afterwards, the relative movement between the rotating sleeve and the ball rod can cause the ball rod to control the corner column to drive the ejector pin to move a specified distance toward the dynamic membrane plate under the action of the internal snake groove of the sleeve. This can realize the dynamic gradient feed adjustment of the vertical distance between the ejector pin and the dynamic membrane frame at different times, and unify the operating depth between the ejector pin and the filter cake layer in real time during each single operation.

[0039] S2: Then, through the staggered relative movement between the water distribution plate and the dynamic diaphragm plate, the heat conduction columns at different positions implement staggered temperature control on the beads at corresponding positions. There is a gap in the temperature control between the two beads, creating an interactive temperature difference environment between the beads and the dynamic diaphragm plate. The beads perform a fitting "first expansion" high-temperature shaping and "later cooling" low-temperature shaping on the inner wall of the dynamic diaphragm plate tooth groove. The air column is used to fill the interior of the ball head with high-pressure gas to flush the filter cake layer in the ejector shear area, dredging the tooth groove while ensuring the stability of the cross-section of each area in the front and rear working areas of the tooth groove.

[0040] S3: Finally, through the connection between the sliding plate and the movable plate, the meshing state between the side gear and the driven gear is changed during the meshing process of the side rack and the side gear, so that the split frame drives the current membrane side frame to move away from the shaft seat. At the same time, the vertical beam controls the horizontal side frame to drive the exposure and washing unit to alternate with the aforementioned membrane side frame, thereby ensuring that a single exposure and washing unit can continuously clean the filter cake layer on the surface of the rear-end dynamic template when the position is alternating.

[0041] The present invention has the following beneficial effects:

[0042] 1. The present invention promotes the interaction between the horizontal frame and the fixed point position during each single cycle of movement, so as to cause the single-side sheath plate, which has a constant relative position and can only deflect in one direction, to generate relative engagement movement with the tooth opening of the position gear. Afterwards, the eccentric wheel drives the crankshaft to rotate eccentrically by a certain angle under the control of the position gear. At this time, the crankshaft, under different eccentric states, synchronously changes the relative action depth between the rubber plug and the exposure and washing chamber through the connection continuity between the connecting plate, the connecting shaft and the face plate, that is, changes the single stamping space between the rubber plug and the exposure and washing chamber, and periodically changes the degree of interaction between the rubber plug and the exposure and washing chamber, thereby changing the unit flow rate of gas flowing to the ball head during a single stamping of the rubber plug, and gradient-adaptively increases the instantaneous pressure of gas outflow, ensuring that the degree of gas interaction with the filter cake layer is relatively identical when the thickness of the filter cake layer is reduced, linearly unifying the impact strength of the front and rear gases to a certain extent, reducing the damage to the surface coating of the dynamic diaphragm plate caused by unstable air pressure, and thereby improving the consistency of the front and rear filtration accuracy of the dynamic diaphragm plate.

[0043] 2. The present invention uses the consistency of movement between the vertical beam, the movable plate and the sliding plate to enable the movable plate to drive the vertical beam to move toward the membrane side frame. The outlet frame, under the meshing of the driven rack with the side gear, synchronously controls the current position of the membrane side frame to move toward the vertical beam until the vertical beam and the membrane side frame alternate in position. Under the premise of ensuring that the dynamic membrane plates are fully arranged in a limited space, the vertical beam intermittently alternates with the membrane side frame to achieve the sequential and orderly cleaning of the filter cake layer on the surface of the dynamic membrane plates at different positions by the exposure and washing unit, thereby reducing the cleaning cost and improving the front and rear filtration accuracy of the dynamic membrane plates.

[0070] Reference Figure 2 、 Figure 3 、 Figure 5 and Figure 6It can be seen that the exchange unit 3 includes: a straight side rail 31, which is plugged and installed at one end of the shaft seat 15 close to the machine cover 12, and the straight side rail 31 is snap-fitted and installed with the inner wall of the chassis 11; a single side rail 32, which is plugged and installed at the other end of the shaft seat 15 close to the machine cover 12, and the single side rail 32 is snap-fitted and installed with the inner wall of the chassis 11; a sliding plate 33, which is slidably snap-fitted and installed on the opposite sides of the straight side rail 31 and the single side rail 32; two vertical beams 34, which are symmetrically distributed between the straight side rail 31 and the single side rail 32, and the vertical beams 34 are snap-fitted and installed with the sliding plate 33; a sheet plate 35, which is snap-fitted and installed in an array on the end face of the straight side rail 31 close to the single side rail 32;

[0071] The side gear 36 is installed in the middle position of the plate 35 in a through-type plug-in manner through a connecting shaft; the movable plate 37 is slidably mounted on the end surface of the straight side rail 31 close to the machine cover 12, and the movable plate 37 is connected to the sliding plate 33; the side rack 38 is mounted on the end surface of the movable plate 37 close to the single side rail 32, and the side rack 38 is meshed with the side gear 36; the splitter frame 39 is symmetrically mounted on the outer wall of the membrane side frame 17 close to the machine cover 12;

[0072] Reference Figure 4 、 Figure 5 and Figure 6 It can be seen that the split-mouth frame 39 is clamped and installed with a driven rack 311 on the end face close to the straight side rail 31, and the driven rack 311 is meshed and fitted with the side gear 36. The single-side rail 32 is slidingly clamped and fitted with a port frame 312 clamped and fitted with the sliding plate 33 on the end face close to the machine cover 12. The port frame 312 is clamped and installed with a chain plate 313 on the end face close to the straight side rail 31.

[0073] The alternating process between the vertical beam 34 and the multiple membrane side frames 17 positions:

[0074] Precondition: Exposure washing unit 2 completes cleaning of the filter cake layer in the current position of membrane side frame 17 area;

[0075] First, the movable plate 37 drives the side rack 38 to move toward the shaft seat 15 under the support and guidance of the straight side rail 31 (in the initial state, the side rack 38 close to the shaft seat 15 is in extreme meshing with the side gear 36 closest to its end. Similarly, the side gear 36 in the current area is in extreme meshing with the driven rack 311 (the driven rack 311 and the side rack 38 are symmetrically distributed around the axis of the side gear 36 in the current area). In the specific implementation process, the angles of the side gears 36 at different positions are designed to ensure that the side rack 38 can always smoothly enter into meshing with the side gears 36 in different areas during movement). In the specific implementation, the movable plate 37 can be driven to move by the electric slider until the side rack 38 is completely meshed with the side gear 36.

[0076] Next, the side gear 36 (the furthest end in a straight line from the coaxial seat 15) meshes with the driven rack 311. During this process, the membrane side frame 17 provides stable support to the branch frame 39. At the same time, the movement synchronization between the branch frame 39 and the driven rack 311 causes the membrane side frame 17 in the current position to move away from the shaft seat 15 (in specific implementation, the vertical beam 34 is higher than the membrane side frame 17, and the vertical distance between the two is greater than the width of the membrane side frame 17. In this way, collision and position limiting between the membrane side frame 17, the vertical beam 34, and the exposure and washing unit 2 are avoided, thereby ensuring the safety and uniformity of the operations between the exchange unit 3 and the exposure and washing unit 2).

[0077] Finally, through the orderly connection between the movable plate 37, the sliding plate 33 and the vertical beam 34, the membrane side frame 17 and the vertical beam 34 are moved toward each other. After that (when the exposure and washing unit 2 completes the processing of the filter cake layer in the area of ​​the other single membrane side frame 17 at the rear end), the movable plate 37 continues to control the side rack 38 to move toward the shaft seat 15 until the vertical beam 34 and the membrane side frame 17 (the closest end of the coaxial seat 15) are completely alternately positioned. In specific implementation, when the vertical beam 34 returns to its initial position, the movable plate 37 can drive the sliding plate 33 to move in the opposite direction, and the position of the membrane side frame 17 is alternated again.

[0078] During this process, the movement consistency between the port frame 312 and the sliding plate 33 enables the port frame 312, under the support and guidance of the single-side rail 32, to drive the chain plate 313 under the further guidance of the branch frame 39, thereby providing a further stable support environment for the vertical beam 34 and improving the movement accuracy of the vertical beam 34.

[0079] Chassis 11 and cover 12: The chassis 11 blocks the communication channels between the exposure and washing unit 2 and the exchange unit 3 and the outside, providing a certain degree of physical protection. At the same time, the cover 12 provides flexible sealing management for the chassis 11, simplifying the difficulty of later maintenance while facilitating assembly and transportation.

[0080] Angle steel plate 14: reinforces weak corner nodes to resist torsion and vibration stress, provides standardized installation interface and positioning reference, and assists in fixing the radiator 13 structure to enhance electromagnetic shielding continuity;

[0081] Shaft seat 15 and bracket 16: provide a stable supporting environment for membrane side frame 17, coordinate the layout rationality of exposure and washing unit 2 and exchange unit 3 inside chassis 11, optimize the discontinuity position between membrane side frames 17 inside chassis 11, and intermittently improve the filtration and separation effect;

[0082] Hanging beam 18: reasonably interrupts the spatial distance between the membrane side frame 17 and the dynamic membrane plate 21, provides a stable and operable processing environment for the exposure and washing unit 2, and ensures the integrity of the cleaning.

A connecting rod 228 is rotatably mounted on the middle position of the panel 227. Connecting plates 229 are rotatably mounted on both ends of the connecting rod 228.

[0087] Reference Figure 8 、 Figure 9 、 Figure 10 and Figure 11 It can be seen that the connecting plate 229 is rotatably mounted on the end away from the connecting rod 228 with a crankshaft 231, and the two opposite crankshafts 231 are not connected.

A connecting roller 233 is rotatably mounted between the two adjacent eccentric wheels 232. The outer wall of the angle hanging plate 223 away from the middle position of the horizontal side frame 1 is clamped and mounted with an angle plate 234.

The inner wall of the dividing gear 237 is symmetrically clamped with an ear plate 238. A single-side sheath plate 239 is rotatably mounted between the ear plates 238 through a torsion spring.

[0088] Reference Figure 2 、 Figure 7 and Figure 11 It can be seen that a top beam 241 is provided in the space on the side of the horizontal frame 1 away from the dynamic diaphragm plate 21, and a vertical section of the top beam 241 is clamped and installed with a mouth frame 242 clamped and installed with the vertical beam 34 on the end face of the side of the horizontal frame 1, and a horizontal section of the mouth frame 242 is clamped and installed with a mosaic plate 243 on the end face of the side of the horizontal frame 1. The mosaic plate 243 is symmetrically clamped and installed with an ear seat 244 in the middle position of the end face of the side of the horizontal frame 1, and the ear seats 244 are in a group of two, and there is at least one group. A wedge plate 245 is installed between the two ear seats 244 of the same group through a coupling for rotation. A coil spring 246 is clamped and installed between the wedge plate 245 and the ear seat 244. A limiting column 247 clamped and installed with the mosaic plate 243 is provided in the space on one side of the wedge plate 245 to limit the turning of the wedge plate 245.

[0089] The blocking guard plate 212, the ball head 27, the ball 29 and the ejector pin 219 are distributed in sequence along the direction of gravity, and the diameter of the ball 29 is one-fourth of the width of the tooth grooves between the dynamic diaphragm plates 21. The diameter of the ball head 27 is equal to the width between the tooth grooves of the dynamic diaphragm plates 21. The vertical distance between the two vertical beams 34 is greater than the width between the membrane side frames 17. At the same time, the height of the vertical beam 34 is greater than the height of the membrane side frames 17.

[0090] The gradient change process of a single aeration volume from the ball head 27 to the tooth groove of the dynamic membrane plate 21 is as follows:

[0091] First, when the position of the vertical beam 34 alternates, due to the connection between the vertical beam 34 and the opening frame 242, the interlocking plate 243 is controlled by the opening frame 242 (the sliding engagement between the top beam 241 and the cover 12 further ensures the stability of the movement of the interlocking plate 243), and the height of the interlocking plate 243 relative to the membrane side frame 17 remains unchanged (in the direction of gravity), thereby ensuring the consistency of the interaction between the dividing gear 237 and the wedge plate 245 during each single cycle of movement;

[0092] Then, when the dividing gear 237 moves toward the interlocking plate 243, the wedge plate 245 can only flip in the direction away from the machine cover 12 due to the existence of the limiting post 247. At this time, the dividing gear 237 is constantly engaged with the wedge plate 245 (when the dividing gear 237 moves synchronously with the horizontal frame 1 in the direction away from the machine cover 12, the teeth of the dividing gear 237 squeeze the wedge plate 245, and the wedge plate 245 flips under the support of the ear seat 244. After the dividing gear 237 is separated from the wedge plate 245, the wedge plate 245 rotates to its initial horizontal state under the elastic restoring force of the coil spring 246). The dividing gear 237 synchronously drives the eccentric wheel 232 to rotate a specified angle, and the relative eccentricity between the crankshaft 231 and the eccentric wheel 232 changes.

[0093] During this process (the sub-position gear 237 moves toward the machine cover 12), after the sub-position gear 237 flips a unit angle, the unilateral sheath plate 239, which rotates in one direction (turning direction: opposite to the rotation direction of the sub-position gear 237), flips a certain angle under the support of the ear plate 238 until the unilateral sheath plate 239 moves from one tooth opening of the main position gear 236 to the other tooth opening. Thereafter, due to the rotation restriction of the unilateral sheath plate 239 and the restriction of the end rod 235 on the rotation of the main position gear 236 (the main position gear 236 does not rotate, and the connection rigidity between the end rod 235 and the washing chamber 23 is improved by the angle bracket), the sub-position gear 237 is forced to rotate in one direction as much as possible. The unidirectionally rotating sub-position gear 237 can cyclically adjust the eccentricity between the eccentric wheel 232 and the crankshaft 231.

[0094] Finally, when the position of the eccentric wheel 232 changes, the crankshaft 231 synchronously pulls the panel 227 toward the washing chamber 23 by a specified distance through the connecting plate 229 and the connecting shaft. Under the action of the panel 227, the vertical rod 226 lifts the rubber plug 224 through the ball pin 225 to move synchronously into the washing chamber 23. At this time, the stamping space between the rubber plug 224 and the washing chamber 23 is reduced by a specified equivalent. Since the length of the connecting plate 229 remains unchanged, when the crankshaft 231 rotates at a constant speed (in specific implementation, adjacent crankshafts 231 are not connected to avoid collision and position limitation with the connecting plate 229 during rotation), the rubber plug 224 is stamped once, and the pressure gradient of the gas flowing into the ball head 27 increases (the filter cake layer is flushed layer by layer, so the distance between the ball head 27 and the filter cake layer increases in a gradient. The gradient changes the flushing pressure to ensure the consistency of the degree of interaction between the ball head 27 and the filter cake layer). In specific implementation, the crankshaft 231 can be driven to rotate by an external motor.

[0095] In specific implementation, adjacent crankshafts 231 are mounted in a snap-fit ​​manner. In order to further reduce cleaning costs during actual use, it should be understood that the crank slider movement composed of the exposure and washing chamber 23, the rubber plug 224, the ball pin 225, the vertical rod 226, the end plate 218, the connecting rod 228 and the connecting plate 229 can be centralized and "dispersed into one";

[0096] As the thickness of the filter cake layer gradually decreases, the ejector pin 219 moves in a gradient manner toward the dynamic membrane plate 21:

[0097] Precondition: Referring to the principle of unidirectional rotation of the eccentric wheel 232, in specific implementation, the outer wall of the end of the sleeve 222 away from the dynamic diaphragm 21 can be clamped and installed with the dividing gear 237, the corner plate 234, the end rod 235, the main gear 236 and the interlocking plate 243, so as to achieve the sleeve 222 in the same position and a unit rotation of a certain angle;

[0098] When the shaft sleeve 222 rotates, the inner wall groove thereof is engaged to a certain extent with the ball rod 221. Under the joint support and guidance of the stop plate 214 and the node plate 213, the straight column 215 controls the corner column 217 to drive the end plate 218 to move a certain distance toward the dynamic membrane frame, linearly adjusting the relative distance between the ejector pin 219 and the filter cake layer to ensure the relative depth of the ejector pin 219 before and after (and when the ball rod 221 runs from the snake groove head end to the tail end, it can move back to the initial position through the straight groove, and the elastic force of the return spring 216 itself provides the source driving force to the straight column 215). In specific implementation, the ejector pins 219 are densely distributed (gradiently) along the gravity direction, reducing the initial friction while avoiding the later filling and retention of the filter cake layer in the gap area of ​​the ejector pins 219, thereby ensuring the cleanliness of the filter cake layer in the tooth groove area of ​​the dynamic membrane frame;

[0099] Cleaning process of the filter cake layer between the teeth of the dynamic membrane plate 21:

[0100] Through the relative movement between the aforementioned ejector pin 219 and the dynamic membrane plate 21, a gradient feed shearing process is performed on the filter cake layer on the surface of the dynamic membrane frame, thereby destroying the physical state between the filter cake layers. Subsequently, through the staggered relative movement between the water diversion plate 25 and the dynamic membrane plate 21, the heat conducting columns 28 at different positions implement staggered temperature control on the balls 29 at corresponding positions, and there is a gap in the temperature control between the two balls 29, thereby creating an interactive temperature difference environment between the balls 29 and the dynamic membrane plate 21, so that the balls 29 perform a fitting "first stretching" high-temperature shaping and "later cooling" low-temperature shaping on the inner wall of the tooth groove of the dynamic membrane plate 21. In addition, high-pressure gas is filled into the interior of the ball head 27 through the gas column 26 to perform exposure and flushing on the filter cake layer in the shearing area of ​​the aforementioned ejector pin 219, thereby clearing the tooth groove and ensuring the stability of the cross-section of each area in the front and rear working areas of the tooth groove.

[0101] Finally, the gas is sprayed through the ball head 27 to perform a final cleaning treatment on the residual filter cake layer between the teeth of the dynamic diaphragm plate 21. It should be understood that in specific implementation, the heat-conducting column 28 and the water-dividing plate 25 can be set to be elastically connected, so as to further ensure that the balls 29 shape and finalize the teeth of the dynamic diaphragm plate 21.

[0102] The present invention provides a self-cleaning dynamic membrane separation and environmentally friendly pesticide filtration integrated infiltration method as follows: Step 1: First, the vertical beam 34 provides a stable movement guide for the horizontal frame 1. During this process, the exposure and washing chamber 23, under the control of the U-shaped frame 22, drives the ejector pin 219 through the water distribution plate 25 to generate relative shear movement with the filter cake layer on the surface of the dynamic membrane plate 21;

[0103] Afterwards, the relative movement between the rotating sleeve 222 and the ball rod 221 can cause the ball rod 221 to control the corner column 217 to drive the ejector pin 219 to move a specified distance toward the dynamic membrane plate 21 under the action of the internal snake groove of the sleeve 222, thereby realizing dynamic gradient feed adjustment of the vertical distance between the ejector pin 219 and the dynamic membrane frame at different times, and real-time unifying the operating depth between the ejector pin 219 and the filter cake layer during each single operation;

[0104] Step 2: Then, through the staggered relative movement between the water diversion plate 25 and the dynamic diaphragm plate 21, the heat conducting columns 28 at different positions implement staggered temperature control on the balls 29 at corresponding positions, and there is a gap in the temperature control between the two balls 29, creating an interactive temperature difference environment between the balls 29 and the dynamic diaphragm plate 21, so that the balls 29 implement a fitting "first expansion" high-temperature shaping and "later cooling" low-temperature shaping on the inner wall of the tooth groove of the dynamic diaphragm plate 21. The gas column 26 is used to fill the interior of the ball head 27 with high-pressure gas to flush the filter cake layer in the shearing area of ​​the ejector pin 219, dredging the tooth groove while ensuring the stability of the cross-section of each area in the front and rear working areas of the tooth groove;

[0105] Step 3: Finally, through the connection between the sliding plate 33 and the movable plate 37, the meshing state between the side rack 38 and the side gear 36 is changed, so that the meshing state between the side gear 36 and the driven gear is changed, so that the opening frame 39 drives the current membrane side frame 17 to move away from the shaft seat 15. At the same time, the vertical beam 34 controls the horizontal side frame 1 to drive the exposure and washing unit 2 to alternate with the aforementioned membrane side frame 17, thereby ensuring that the single exposure and washing unit 2 can continuously clean the filter cake layer on the surface of the rear dynamic template when the position is alternating.
