Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device based on water pollution. Background Technology

[0002] In today's society, wastewater treatment equipment plays a vital role. Its main function is to effectively treat various types of wastewater, removing harmful substances such as color, chemical oxygen demand (COD), and suspended solids, thus reducing environmental pollution. With increasingly scarce water resources, the operation of wastewater treatment equipment also helps to achieve water recycling, reduce production costs, and improve the economic and social benefits of enterprises. Furthermore, effective wastewater treatment can protect the surrounding ecological environment and residents' health. The technical level and treatment efficiency of wastewater treatment equipment are receiving increasing attention, highlighting its growing importance. For example, Chinese Patent Publication No. CN114804276B discloses a high-efficiency decolorization treatment machine for textile dyeing and printing wastewater, including a machine body. A partition is fixedly connected to the inner wall of the machine body. A mixing mechanism is provided within the machine body. The mixing mechanism includes multiple bidirectional reciprocating screws rotatably connected to the inner wall of the machine body above the partition. Two first rings are threaded to the side walls of the bidirectional reciprocating screws. Two second rings are connected to the side walls of the two first rings respectively through a connecting mechanism. Multiple hollow elastic rods are fixedly connected between the side walls of the two second rings that are close to each other. This invention employs a mixing mechanism where a bidirectional reciprocating screw rotates, causing two second rings to intermittently move closer and further apart. This allows multiple elastic rods to be intermittently stretched and compressed, resulting in continuous shape changes within the machine and improving the mixing efficiency of colored wastewater and decolorizing agents. However, the photoresistor in this device detects the transmittance of light through the wastewater. While color intensity does affect transmittance, tiny suspended particles and fiber debris also scatter and absorb light, leading to a decrease in the light intensity detected by the photoresistor. In practical applications, this combined effect may cause the detection device to misjudge the decolorization effect of the wastewater, failing to accurately reflect the true color removal situation.

Simultaneously, a rotating component drives an arc-shaped disk to deflect and release the scum, allowing it to collect wastewater and scum during gravity resetting. As the wastewater flows over the surface of the arc-shaped disk, the fibers are caught and trapped by barbs, while the wastewater flows back into the tank through the outlet, achieving dynamic fiber separation. During this process, a detection component continuously monitors the light transmittance fluctuation characteristics. If the fluctuation value tends to stabilize, it is determined that the fiber interference has been eliminated, at which point an appropriate amount of decolorizing agent can be added.

[0029] 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, and 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.

[0030] Please see Figures 1 to 10 The present invention provides a technical solution: a sewage treatment device based on water pollution, including a box 1, a bubble generating device 11 fixedly installed on the inner wall of the box 1, a ball-jointed mounting rod 7 provided at the top of the box 1, an arc-shaped disk 8 fixedly installed at the bottom of the mounting rod 7, a number of barbs 20 provided at the top of the arc-shaped disk 8, and a number of water outlet holes 21 provided at the center of the top of the arc-shaped disk 8.

[0031] It also includes a rotating component that enables the arc-shaped disk 8 to deflect around the ball hinge point in multiple axes;

[0032] It also includes a detection component, which detects the light transmittance of the sewage inside the tank 1 by vertically shining light through the sewage.

[0033] See Figure 1 and Figure 2 When textile wastewater needs to be treated, the staff mixes the wastewater with the decolorizing agent and pours it into the tank 1. The detection component is then activated to test the light transmittance of the wastewater inside the tank 1. When the detection component detects that the light transmittance of the wastewater is lower than the set threshold, there may be two reasons: First, too little decolorizing agent is added, resulting in insufficient decomposition of the dyeing substances in the wastewater, thus reducing the light transmittance; Second, the content of fiber impurities in the wastewater is too high, causing a significant decrease in light transmittance.

[0034] At this time, by activating the bubble generating device 11, the bubble generating device 11 continuously releases microbubble clusters inside the tank 1. After release, these bubbles float to the top of the water surface, and during the floating process, they combine with fibers suspended in the sewage to form bubble-fiber aggregates. Under the action of buoyancy, the fibers are driven to float to the water surface and float to the surface to form a scum layer. At the same time, the rotating component drives the arc-shaped disk 8 to deflect around the ball hinge point. See Figure 1 In the initial state, part of the bottom of the arc-shaped disk 8 is immersed in water. After deflection occurs (see...), Figure 9 One edge of the arc-shaped disk 8 is submerged in the water. At this time, the arc-shaped disk 8 is released by rotating the component. The arc-shaped disk 8 will move back to its original position under the action of gravity. During this process, sewage and part of the scum layer on the liquid surface will be collected into the arc-shaped disk 8. During the resetting process, the sewage collected into the arc-shaped disk 8 will flow on its surface, thereby passing over the barbs 20 at the top of the arc-shaped disk 8. The fibers will be hooked by the barbs 20 (the barbs 20 can be a hook side or a velvet side similar to Velcro). The residual sewage will flow back into the tank 1 through the water outlet 21. This process is repeated continuously to treat the fibers in the sewage and complete the dynamic interception and separation of the fibers.

[0035] While the above process is repeated, the rotating component drives the arc-shaped disk 8 to deflect in different directions, thereby cleaning a larger area of ​​the sewage surface to achieve more efficient separation. The detection component continuously detects the sewage inside the tank 1. When the light transmittance is due to excessive fiber content, the detection result will fluctuate. When this fluctuation is at a relatively stable value, the influence of fibers on the light transmittance of the sewage can be eliminated. At this time, the staff can add an appropriate amount of decolorizing agent inside the tank 1.

[0036] It is worth mentioning that when the rotating component causes the arc-shaped disk 8 to shift, such as Figure 8As shown, the arc-shaped disk 8 shifts to the right. At this time, the sewage and scum layer will be pushed by the arc-shaped disk 8 towards the inner wall of the tank 1. The detection component can detect the light transmittance at this point. If the fluctuation value of the light transmittance at this point is within a stable range, the influence of the fiber on the light transmittance can be eliminated, thereby determining whether the decolorizing agent is used in appropriate amounts.

[0037] Furthermore, the rotating assembly includes a mounting sleeve 10 installed at the bottom center of the housing 1, which is rotatable. A fixed shell 30 is fixedly installed on the outer wall of the mounting sleeve 10. A sliding frame 24 is installed on the inner wall of the fixed shell 30. A second permanent magnet 23 is fixedly installed on the top of the sliding frame 24. Several first permanent magnets 22 that can cooperate with the second permanent magnet 23 are fixedly installed on the bottom of the arc-shaped disk 8. When the arc-shaped disk 8 is in a horizontal state, one of the first permanent magnets 22 is in contact with the second permanent magnet 23. When the arc-shaped disk 8 is in a horizontal state, at least one first permanent magnet 22 is in position corresponding to the second permanent magnet 23.

[0038] See Figure 2 as well as Figure 3 In the initial stage, one of the first permanent magnets 22 and the second permanent magnet 23 are in close contact. When it is necessary to deflect the arc-shaped disk 8, the external drive component drives the sliding frame 24 to slide inside the fixed shell 30, thereby causing the second permanent magnet 23 to slide. When the second permanent magnet 23 slides, under the action of magnetic force, it will drive the first permanent magnet 22 to move together, thereby causing the arc-shaped disk 8 to rotate at the ball joint. As the arc-shaped disk 8 deflects, its edge gradually sinks into the sewage and begins to collect the sewage and scum layer. As the sliding frame 24 moves a distance that gradually increases, the second permanent magnet 23... The distance between the permanent magnet 23 and the first permanent magnet 22 will gradually increase. When the distance between the second permanent magnet 23 and the first permanent magnet 22 exceeds the preset distance, the attraction of the second permanent magnet 23 to the first permanent magnet 22 will not be enough to drive the arc disk 8 to continue to deflect. At this time, under the action of gravity, the arc disk 8 begins to reset. At the same time, the mounting sleeve 10 is driven to rotate by a predetermined angle through the external drive component, thereby resetting the sliding frame 24. When the sliding frame 24 is reset, it will align with the next first permanent magnet 22 and form a new magnetic attraction pair, preparing for the next deflection.

[0039] Furthermore, the sliding frame 24 is connected to the fixed shell 30 by a second spring 29. A rotatable screw 25 is installed on the inner wall of the fixed shell 30. A pin 26 is provided through the bottom of the sliding frame 24. The pin 26 can slide vertically and its lower end can be embedded in the threaded groove of the screw 25. The top of the pin 26 is connected to the top of the inner wall of the sliding frame 24 by a first spring 28. The top of the pin 26 is provided with an unlocking slope. An unlocking rod 27 is provided through the side wall of the sliding frame 24 laterally. One end of the unlocking rod 27 contacts and abuts against the unlocking slope of the pin 26, and the other end of the unlocking rod 27 can contact and abut against the inner wall of the fixed shell 30. The part of the pin 26 that extends through the bottom of the sliding frame 24 is provided with elastic micro-particles.

[0040] See Figure 3 As can be seen from the above, when it is necessary to shift the arc-shaped disk 8, the first permanent magnet 22 is moved by driving the second permanent magnet 23, thereby achieving the deflection of the arc-shaped disk 8. When it is necessary to move the second permanent magnet 23, the screw 25 is rotated by the external drive component. At this time, under the action of the first spring 28, the bottom end of the pin 26 will be embedded in the thread groove of the screw 25. The rotation of the screw 25 will drive the pin 26 and the sliding frame 24 to move in a direction that gradually squeezes the second spring 29 and moves away from the mounting sleeve 10, thereby driving the second permanent magnet 23 to move, thereby achieving the purpose of shifting the arc-shaped disk 8 through magnetic force.

[0041] During the sliding process of the sliding frame 24, it will gradually approach the inner wall of the other side of the fixed shell 30. When the unlocking rod 27 contacts the inner wall of the fixed shell 30, it will push the unlocking rod 27 into the sliding frame 24, and the sliding frame 24 will make unlocking contact with the pin 26, thereby driving the pin 26 to move upward and gradually disengage from the threaded groove of the screw 25. When the two are completely disengaged, the elastic particles on the outer wall of the pin 26 will be squeezed into the through-hole of the sliding frame 24 and prevent the pin 26 from resetting. At this time, it will quickly reset under the action of the second spring 29. When the sliding frame 24 contacts the outer wall of the left side of the fixed shell 30 under the action of the elastic force, the bottom of the pin 26 will be re-embedded into the threaded groove of the screw 25 under the action of vibration and the action of the first spring 28, preparing for the next displacement of the arc-shaped disk 8.

[0042] Furthermore, the top of the housing 1 is provided with a limiting tube 4 that communicates with the interior of the housing 1. A sliding rod 6 is slidably installed on the inner wall of the limiting tube 4. The top of the sliding rod 6 is connected to the top of the inner wall of the limiting tube 4 by a first tension spring 5. The bottom of the sliding rod 6 is connected to the top of the mounting rod 7 by a ball joint.

[0043] See Figure 2In previous embodiments, a portion of the arc-shaped disk 8 was always submerged in the liquid, and a portion of the barbs 20 was constantly immersed in water. This resulted in some fiber separation occurring underwater. The lubricating effect of the water reduced the bonding efficiency between the barbs 20 and the fibers. To address this issue, when the arc-shaped disk 8 deflects due to the movement of the second permanent magnet 23, and the attraction of the second permanent magnet 23 to the first permanent magnet 22 does not support further deflection of the arc-shaped disk 8, during the reset process of the arc-shaped disk 8, the first tension spring 5, through the sliding rod 6, will... 7. Pull upwards to completely detach the arc-shaped disk 8 from the blade. At this time, the barbs 20 will be exposed to the air. The fibers lose the lubrication of water, and the bonding force with the barbs 20 is significantly improved. At the same time, the sewage in the arc-shaped disk 8 flows back to the inside of the box 1 through the water outlet 21. When the mounting sleeve 10 rotates and the sliding frame 24 resets, the second permanent magnet 23 will correspond to the next first permanent magnet 22 and attract it, thereby pulling the first tension spring 5 again, so that the arc-shaped disk 8 is immersed in the water surface again, and the system enters the next cycle.

[0044] Furthermore, a central rod 9 is rotatably mounted on the inner wall of the mounting sleeve 10. The central rod 9 is driven to rotate by an external drive assembly. A second bevel gear 33 is fixedly mounted on the top of the central rod 9. A screw 25 penetrates the outer wall of the mounting sleeve 10, and a first bevel gear 32 is fixedly mounted on the outer wall of the screw 25 that penetrates the outer wall of the mounting sleeve 10. The second bevel gear 33 meshes with the first bevel gear 32.

[0045] See Figure 6 The center rod 9 is driven to rotate by an external motor, which in turn drives the second bevel gear 33 to rotate. The meshing of the second bevel gear 33 and the first bevel gear 32 transmits power to the screw 25. The rotation of the screw 25 pushes the pin 26 to generate axial displacement through the threaded groove, which in turn drives the sliding frame 24 and the second permanent magnet 23 to move, so as to achieve the purpose of deflecting the arc-shaped disk 8.

[0046] Furthermore, a mounting shell 14 is fixedly installed at the bottom of the housing 1. A central rod 9 passes through the bottom of the housing 1 and is rotatably connected to the top of the mounting shell 14. A rotating gear 18 is fixedly connected to the outer wall of the central rod 9. A driven gear 19 that meshes with the rotating gear 18 is rotatably installed at the top of the mounting shell 14. A driving component 17 is also coaxially fixed to the driven gear 19. One end of the driving component 17 is arc-shaped, and the other end is rod-shaped. A protrusion 31 is fixedly connected to the top of the rod-shaped driving component 17. A driving ring 15 is fixedly connected to the outer wall of the mounting sleeve 10. Several arc-shaped grooves corresponding to the driving component 17 are arranged in a ring on the inner wall of the driving ring 15. Several limiting guide rails 16 are provided at the bottom of the driving ring 15, and the protrusion 31 can selectively embed into the limiting guide rails 16.

[0047] See Figure 2 , Figure 4 as well as Figure 5 The center rod 9 is driven to rotate by a motor fixed to the bottom of the mounting housing 14. When the center rod 9 rotates, it drives the rotating gear 18 and the driven gear 19 to rotate. The rotation of the center rod 9 drives the second bevel gear 33 to rotate. The rotation of the driven gear 19 drives the driving component 17 to rotate. The rotation of the driving component 17 causes the arc surface of the driving component 17 to periodically contact and separate from the arc groove of the driving ring 15. When the arc surface of the driving component 17 is in contact with the arc groove of the driving ring 15, it will limit the driving ring 15 and the mounting sleeve 10 to prevent them from collapsing. When the arc-shaped surface of the driving component 17 disengages from the arc-shaped groove of the driving ring 15, the protrusion 31 on its other top side aligns with and embeds into the limiting guide rail 16 at the bottom of the driving ring 15, driving the limiting guide rail 16 to rotate. This, in turn, enables the driving ring 15 to rotate periodically, thereby causing the mounting sleeve 10 and the fixed shell 30 to rotate periodically. This achieves the purpose of deflecting the arc-shaped disk 8 at different angles. Through mechanical intelligent transmission, this mechanism perfectly realizes the precise control of the "adsorption-separation-discharge" action chain of fibrous impurities in the sewage treatment process.

[0048] Furthermore, a sealing ring is provided at the connection between the bottom of the housing 1 and the mounting sleeve 10.

[0049] A sealing ring is installed at the contact point between the bottom of the housing 1 and the mounting sleeve 10, which can effectively prevent sewage from seeping into the interior of the rotating parts. The sealing ring is made of fluororubber and forms a double sealing barrier through interference fit, which not only prevents sewage from corroding the bearing, but also avoids transmission jamming caused by impurities entering.

[0050] Furthermore, the top of the box 1 is provided with a liquid inlet 3, and the outer wall of the box 1 is provided with a liquid outlet 2.

[0051] See Figure 1 In the initial stage, the staff can discharge the pre-mixed wastewater into the tank 1 through the inlet 3. After the fiber separation in the wastewater is completed, the decolorizing agent can also be introduced into the tank 1 through the inlet 3 to supplement the reaction of the treated wastewater. When the treatment is completely completed, the upper cleaning can be discharged through the outlet 2, and the pipe can be extended into the tank 1 from the outlet 2 to clean the bottom of the tank 1 and collect the sediment.

[0052] Furthermore, the bottom of the arc-shaped disk 8 is provided with several radially distributed guide ridges.

[0053] See Figure 9 When the arc-shaped disk 8 shifts, the guide ridges at the bottom of the arc-shaped disk 8 will cause the water flow to generate directional eddies, causing fibrous impurities in the sewage to accumulate towards the edge of the disk, such as... Figure 8As shown by the middle arrow, it can increase the flow of water, which not only prevents the scum layer from settling below the arc-shaped disk 8, but also works with the detection components to detect the fiber content in the water.

[0054] Furthermore, the detection component includes a plurality of spotlights 12 mounted in a ring array on the top of the housing 1, and a plurality of photoresistors 13 corresponding to the spotlights 12 are fixedly mounted on the inner wall of the housing 1, and the photoresistors 13 are connected to an external circuit.

[0055] This detection component enables real-time monitoring of wastewater transmittance through the corresponding arrangement of spotlights 12 and photoresistors 13. The circular array of spotlights 12 forms multi-angle light source coverage, which, together with the photoresistors 13 on the side wall of the housing 1, can eliminate detection blind spots. By comparing the differences in light intensity attenuation at different locations, it can be determined whether the decrease in transmittance is due to insufficient decolorizing agent or excessive fiber, thus enabling precise adjustment.

[0056] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the specification and drawings can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
