TECHNICAL FIELD

[0001] The present application relates to the technical field of high-concentration wastewater treatment, in particular to a hydrophobic membrane treatment device for high-concentration wastewater. BACKGROUND

[0002] Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify wastewater and reduce pollution, so as to achieve wastewater recycling and reuse and fully utilize water resources. The patent application with the publication number CN102241431A discloses an oxygen supply device for space wastewater treatment. The device is connected in series in a wastewater treatment liquid circulation loop. The oxygen supply device mainly consists of an oxygen supply membrane assembly, a pressure sensor, an electromagnetic valve, a flow meter, a pressure reducing valve and an oxygen storage bottle. The membrane wire in the oxygen supply membrane assembly is made of hydrophobic polyvinylidene fluoride (PVDF) material with high oxygen permeability. The two ends of the membrane wire are packaged in the oxygen supply membrane assembly shell through epoxy resin.

[0013] The present application provides a hydrophobic membrane treatment device for high-concentration wastewater, which has the following beneficial effects: 1. By setting up a wastewater treatment mechanism, the wastewater entering the filter cylinder rotates back and forth, and this rotation creates a centrifugal force field on the surface of the hydrophobic membrane filter. This causes larger suspended particles in the wastewater to be subjected to greater radial acceleration, accelerating their migration to the outside of the filter. This allows larger particles filtered by non-hydrophobic membrane filters to concentrate and accumulate on the outside of the hydrophobic membrane filter, reducing the deposition time of larger particles on the filter surface and thus reducing the risk of filter clogging. 2. By setting up a wastewater treatment mechanism, the present invention keeps the hydrophobic membrane filter from deforming when subjected to the pressure of wastewater, and keeps the pores inside the hydrophobic membrane filter from flowing through it in a stable and uniform manner, thus avoiding the problem of inconsistent water purification and filtration effects under different water pressure conditions. 3. This invention, by setting up a wastewater treatment mechanism, can enlarge the pores inside the hydrophobic membrane filter when it becomes clogged. This allows the second rotating shaft, telescopic rod, and first rotating shaft to keep the hydrophobic membrane filter stable and undeformed under normal conditions. When the pressure is too high, the deformation of the torsion spring can provide space for the hydrophobic membrane filter to deform. This prevents the hydrophobic membrane filter from being damaged by pressure when it becomes clogged, thus protecting the hydrophobic membrane filter. 4. This invention, by setting up a toggle mechanism, enables the counterweight plate to slide continuously, and drives the counterweight plate, toggle rod, and water-dispensing plate to rotate continuously inside the filter cylinder to agitate the wastewater flow. The wastewater is continuously dispersed and diverted through the diversion channel, thereby inducing local turbulence when the fluid moves in the toggle, increasing the contact frequency between the fluid and the filter screen, promoting the diffusion of pollutants to the filter screen surface, improving the filtration rate, and achieving a uniform filtration effect. 5. This invention, by setting up a toggle mechanism, simultaneously drives the brush bristles at the bottom to rotate and sweep the surface of the hydrophobic membrane filter below. Large particles and planar coverings on the surface of the hydrophobic membrane filter are pushed away by the centrifugal force of the rotation and sweeping. With the centrifugal field of the rotation of the hydrophobic membrane filter, larger impurities are pushed to the outer periphery of the surface of the hydrophobic membrane filter as much as possible, further preventing the hydrophobic membrane filter from being blocked by impurities that the non-hydrophobic membrane filter should filter. 6. This invention achieves dynamic cleaning by setting up a tossing mechanism. When the hydrophobic membrane filter screen is at high risk of clogging (such as high-concentration wastewater), the extension and retraction speed of the electric telescopic rod is accelerated to increase the frequency of the filter cylinder swinging the hydrophobic membrane filter screen to avoid clogging. At the same time, it can adaptively extend a larger area of ​​the water-dispersing plate to agitate the wastewater. The centrifugal force of the tossing motion makes the waste near the hydrophobic membrane filter screen move quickly to the outer ring of the hydrophobic membrane filter screen, reducing the risk of clogging. By "cleaning on demand", the local overload of the filter screen is reduced and the service life is extended. 7、The toothbrush can realize self-cleaning of the bristles through the setting of the poking mechanism, when the sliding block slides out, the bristles can be poked by the poking bar at the bottom to shake off the residues adhered on the bristles for a long time, realizing self-cleaning of the bristles.

DETAILED DESCRIPTION

[0016] Example one: please refer to Figures 1-4The application provides a technical scheme: a hydrophobic membrane treatment device for high-concentration wastewater, comprising a filter cylinder 2, a second rotating ring 6 and a first rotating ring 1 rotatably connected to the upper and lower ends of the filter cylinder 2, a water inlet pipe 7 fixedly connected to the top of the second rotating ring 6, a water outlet pipe 5 fixedly connected to the bottom of the first rotating ring 1, and a wastewater treatment mechanism 3 arranged on the outer wall of the filter cylinder 2. The wastewater treatment mechanism 3 comprises: A fixed plate 301 fixedly connected to the outer wall of the first rotating ring 1, an electric telescopic rod 302 fixedly connected to the top of the fixed plate 301, a fixed ring 303 fixedly connected to the top of the electric telescopic rod 302, and the electric telescopic rod 302 used for extending and retracting to push the fixed ring 303 to ascend and descend; A connecting rod 304 in a circular rod structure, one end of the connecting rod 304 fixedly connected to one side of the fixed ring 303, a sliding groove 305 formed in the outer wall of the filter cylinder 2, the other end of the connecting rod 304 slidably connected to the inner wall of the sliding groove 305, a fixed sleeve 306 fixedly connected to the inner wall of the filter cylinder 2, a hydrophobic membrane filter screen 307 fixedly connected to the inner wall of the fixed sleeve 306, and the sliding groove 305 in an inclined shape; In use, high-concentration wastewater is pumped into the water inlet pipe 7, the wastewater in the water inlet pipe 7 passes through the hydrophobic membrane filter screen 307, and the separation and purification of the wastewater are completed through the hydrophobic membrane filter screen 307, and then the wastewater is discharged through the water outlet pipe 5 below, so that the purification treatment effect of the wastewater is achieved; The electric telescopic rod 302 is started to continuously extend and retract, and the fixed ring 303 and the connecting rod 304 are continuously lifted and lowered, when the connecting rod 304 is lifted and lowered, one end of the connecting rod 304 is inserted into the inner wall of the sliding groove 305, and the filter cylinder 2 is continuously rotated back and forth through the inclined groove of the sliding groove 305, the second rotating ring 6 and the water inlet pipe 7 are fixed on the fixed frame, and the filter cylinder 2 can freely rotate between the second rotating ring 6 and the water inlet pipe 7, so that the wastewater in the filter cylinder 2 rotates back and forth, a centrifugal field is formed on the surface of the hydrophobic membrane filter screen 307, the larger suspended particles in the wastewater receive a larger radial acceleration, the larger particles that are not filtered by the hydrophobic membrane filter screen 307 are concentrated and stacked on the periphery of the hydrophobic membrane filter screen 307, the deposition time of the larger particles on the filter screen surface is reduced, and the risk of filter screen blockage is reduced; Embodiment two: please refer to Figures 1-6On the basis of embodiment one, the application provides a technical solution: in practical application, the water pressure of wastewater or water to be treated is not constant. The internal pores of the conventional hydrophobic membrane filter screen are easily changed due to water pressure changes under different water pressure conditions. When the water pressure is too large, the pores may be excessively compressed, resulting in increased water flow resistance and affecting the purification and filtration efficiency; when the water pressure is too small, the pores may not be fully expanded, so that some impurities are easily attached to the surface of the filter screen, also reducing the purification effect. This poor water pressure adaptability problem makes it difficult for the hydrophobic membrane filter screen to maintain stable and efficient purification and filtration performance under different working conditions.

[0017] At the same time, as the use time increases, impurities will gradually accumulate inside the hydrophobic membrane filter screen, causing clogging. Once the filter screen is clogged, the water flow rate decreases, and the pressure on the surface of the filter screen increases sharply. The existing hydrophobic membrane filter screen structure is relatively fixed, and when it bears excessive pressure, the internal fibers are easily damaged, thereby affecting the service life and purification performance of the filter screen. This not only increases the maintenance cost of the equipment, but also may cause the downtime of the production process to be prolonged, reducing the overall production efficiency. Therefore, the inner wall of the fixed sleeve 306 is rotationally connected with the second rotating shaft 311, one side of the second rotating shaft 311 is fixedly connected with the telescopic rod 310, one end of the telescopic rod 310 is fixedly connected with the first rotating shaft 309, the inside of the hydrophobic membrane filter screen 307 is fixedly connected with the fixed column 308, and the first rotating shaft 309 is rotationally connected in the inner wall of the fixed column 308.

[0018] The second rotating shaft 311 and the fixed sleeve 306 inner wall are provided with a torsional spring, which plays a role in rotating the second rotating shaft 311 back to its original position; When the wastewater passes through the sliding groove 305, the sliding groove 305 is fixed by the fixed sleeve 306, and the inside of the sliding groove 305 is fixed by the second rotating shaft 311, the telescopic rod 310, the first rotating shaft 309 and the fixed column 308, so that the hydrophobic membrane filter screen 307 does not deform when subjected to the pressure of wastewater passing through, and the pores inside the hydrophobic membrane filter screen 307 maintain stable and uniform water flow, avoiding the problem of different purification and filtration effects on water quality under conventional different water pressure conditions; When the inside of the hydrophobic membrane filter screen 307 is blocked, the water flow through the hydrophobic membrane filter screen 307 decreases, and the pressure on the surface of the hydrophobic membrane filter screen 307 increases excessively. At this time, the second rotating shaft 311, the telescopic rod 310, and the first rotating shaft 309 that fix the hydrophobic membrane filter screen 307 can be articulated through the articulation between the second rotating shaft 311 and the first rotating shaft 309, overcome the elastic force of the torsional spring between the second rotating shaft 311 and the fixed sleeve 306, make the telescopic rod 310 articulate and tilt, and make the fixed column 308 lower, thereby pulling the center of the hydrophobic membrane filter screen 307 to move downward, and the hydrophobic membrane filter screen 307 forms a downward tapered shape, thereby expanding the pores inside the hydrophobic membrane filter screen 307, and achieving the effect of keeping the hydrophobic membrane filter screen 307 stable and not deformed at ordinary times, while in the case of excessive pressure, the hydrophobic membrane filter screen 307 can be deformed through the deformation of the torsional spring, avoiding the problem of damage to the internal fibers of the hydrophobic membrane filter screen 307 due to excessive pressure, and achieving the effect of protecting the hydrophobic membrane filter screen 307. Embodiment three: please refer to Figures 1-10 On the basis of embodiment one and embodiment two, the present application provides a technical solution: the traditional hydrophobic membrane filter screen filtering system is relatively stable when working, the contact frequency of fluid and filter screen is low, and it is difficult to effectively induce local turbulence. This leads to a slow rate of diffusion of pollutants to the filter screen surface, a low overall filtration rate, and uneven distribution of wastewater on the filter screen, which can cause local filtration load to be too heavy, while other areas are not fully filtered, resulting in a significant reduction in filtration effect.

[0019] When the filter screen surface is attached with a large amount of impurities, cleaning and maintenance are needed. However, the existing filter screen cleaning method is often cumbersome, and needs to be stopped and disassembled for manual cleaning or to use complex automatic cleaning equipment, which not only increases the maintenance cost, but also affects the continuity of production. At the same time, it may be difficult to completely remove all impurities on the filter screen during the cleaning process, resulting in the performance of the filter screen not being fully restored.

[0020] In actual wastewater treatment process, the concentration and flow of wastewater and other working conditions will change continuously. The existing hydrophobic membrane filter screen filtering system usually cannot automatically adjust the filtration parameters according to different working conditions. For example, when treating high-concentration wastewater, the risk of filter screen blockage increases, and the system cannot make timely adjustments to avoid blockage, resulting in unstable filtration effect. Therefore, the outer wall of the fixed column 308 is provided with a poking mechanism 4, the poking mechanism 4 includes a bearing ring 401, the bearing ring 401 is rotatably connected to the outer wall of the fixed column 308, the outer wall of the bearing ring 401 is rotatably connected with an articulation rod 402, one side of the articulation rod 402 is fixedly connected with a poking rod 403, one end of the poking rod 403 is articulated with a counterweight plate 404, and the counterweight plate 404 is slidably connected to the top of the fixed sleeve 306.

[0021] The top of the fixing sleeve 306 is provided with an annular groove 406, and the top of the fixing sleeve 306 is fixedly connected with a baffle 405, one side of the baffle 405 is in contact with one side of the counterweight plate 404, and the bottom of the counterweight plate 404 is slidably connected with the top of the fixing sleeve 306 through the annular groove 406.

[0022] The bottom of the push rod 403 is fixedly connected with a brush 407, the brush 407 is made of elastic material, and the top of the push rod 403 is hingedly connected with a water pushing plate 413, and the inner wall of the water pushing plate 413 is provided with a shunt groove 414.

[0023] One side of the water pushing plate 413 is fixedly connected with an inclined plate 412, and the inclined plate 412 plays a role of counterweight for the water pushing plate 413.

[0024] One side of the push rod 403 is fixedly connected with a sliding strip 408, the outer wall of the sliding strip 408 is slidably connected with a sliding block 409, the bottom of the sliding block 409 is fixedly connected with a push strip 410, the push strip 410 is an L-shaped rod structure, and the top of the sliding block 409 is fixedly connected with a connecting block 411.

[0025] The top of the bearing ring 401 is fixedly connected with an arc-shaped plate 415, the top of the arc-shaped plate 415 is fixedly connected with an elastic rope 416, one end of the elastic rope 416 is fixedly connected with a circular plate 417, and the inner wall of the circular plate 417 is fixedly connected with the top end of the fixed column 308. When the filter cartridge 2 drives the fixing sleeve 306 and the hydrophobic membrane filter screen 307 to rotate, the fixing sleeve 306 drives the baffle 405 to rotate synchronously, and when rotating back and forth, the baffle 405 pushes the counterweight plate 404, and the inertia of the counterweight plate 404 continuously slides forward on the annular groove 406 when the fixing sleeve 306 reverses, so as to realize the continuous sliding of the counterweight plate 404, and drive the counterweight plate 404, the push rod 403 and the water pushing plate 413 to continuously rotate and push the wastewater flow in the filter cartridge 2, and continuously disperse and distribute the wastewater through the shunt groove 414, so that when the fluid is moved, local turbulent flow is induced, the contact frequency of the fluid and the filter screen is increased, the diffusion of pollutants to the surface of the filter screen is promoted, the filtration rate is improved, and the uniform filtration effect is achieved. At the same time, the push rod 403 will drive the brush 407 at the bottom to rotate and clean the surface of the hydrophobic membrane filter screen 307 below, so that the large particles and the surface coverings existing on the surface of the hydrophobic membrane filter screen 307 are pushed away under the centrifugal action of the rotating sweeping, and the larger impurities are pushed to the periphery of the surface of the hydrophobic membrane filter screen 307 as much as possible, so as to further avoid the blockage of the hydrophobic membrane filter screen 307 by the impurities that should not be filtered by the hydrophobic membrane filter screen 307. When the counterweight plate 404 is spun out by the rotation of the baffle 405 with inertia, the toggle lever 403, the articulated lever 402, and the bearing ring 401 are rotated together, at this time, the bearing ring 401 rotates relative to the fixed column 308 on the outer wall of the fixed column 308, then the arc-shaped plate 415 is rotated to pull the elastic rope 416 to deform, and when the counterweight plate 404 is spun out, the elastic force of the elastic rope 416 rebounds to pull the arc-shaped plate 415 to reset, so that the counterweight plate 404 returns to the position of the baffle 405 and is blocked by the baffle 405 again; The counterweight plate 404 plays a counterweight role, so that the hydrophobic membrane filter screen 307 can slide out on the annular groove 406 with the large inertia of the counterweight plate 404 even in slow rotation, the inclined plate 412 plays a role of counterweighting the water dislodging plate 413, so that the water dislodging plate 413 can always be inclined to one side when dislodging wastewater left and right, and when the extension frequency of the electric telescopic rod 302 needs to be adjusted, the extension speed of the electric telescopic rod 302 is faster or slower, which will affect the back-and-forth rotation speed of the filter cartridge 2, so as to make the left and right rotation speed and frequency of the hydrophobic membrane filter screen 307 and the toggle lever 403, then when the swing amplitude of the filter cartridge 2 is larger, the rotating plate will slide out the inclined plate 412 outward due to the larger centrifugal force of the sliding block 409, so that the water dislodging plate 413 is hinged to rotate upward on the toggle lever 403, thereby unfolding a larger area to dislodge the wastewater in the filter cartridge 2, and when the swing amplitude of the filter cartridge 2 is smaller, the water dislodging plate 413 will be hinged to rotate downward due to the counterweight of the inclined plate 412, and push the connecting block 411 and the sliding block 409 back to the original position, thereby reducing the dislodging area of the water dislodging plate 413 to the wastewater, achieving the dynamic cleaning effect, so that when the hydrophobic membrane filter screen 307 has a high risk of blockage such as high-concentration wastewater, the extension speed of the electric telescopic rod 302 is accelerated to strengthen the swing frequency of the filter cartridge 2 and the hydrophobic membrane filter screen 307, so as to avoid blockage and adaptively extend a larger area of the water dislodging plate 413 to dislodge the wastewater, utilize the centrifugal effect of dislodging to make the waste close to the hydrophobic membrane filter screen 307 move quickly to the outer circle of the hydrophobic membrane filter screen 307, thereby reducing the risk of blockage, reducing local overload of the filter screen by “cleaning on demand”, and prolonging the service life; When the sliding block 409 slides out, the bristles 407 can also be locally scraped by the bottom dislodging strip 410 to shake off the residues attached to the bristles 407 for a long time, thereby achieving the self-cleaning effect of the bristles 407.
