Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a sewage treatment device based on water pollution. Background Art

[0002] In today's society, sewage treatment equipment plays a vital role. Its main function is to effectively treat various types of sewage, remove harmful substances such as color, chemical oxygen demand, suspended solids, etc. in sewage, and reduce the pollution of sewage to the environment. With the increasing scarcity of water resources, the operation of sewage treatment equipment can also help to achieve the recycling of water resources, reduce production costs, and improve the economic and social benefits of enterprises. In addition, effective sewage treatment can also protect the surrounding ecological environment and the health of residents. The technical level and treatment efficiency of sewage treatment equipment are also increasingly valued, and their importance is becoming increasingly prominent. For example, Chinese patent publication No. CN114804276B discloses an efficient decolorization treatment machine for printing and dyeing textile sewage, including a body, a partition fixedly connected to the inner wall of the body, a mixing mechanism provided in the body, the mixing mechanism comprising a plurality of bidirectional reciprocating screws rotatably connected to the inner wall of the body above the partition, the bidirectional reciprocating screw side wall being threadedly connected to two first rings, the side walls of the two first rings being respectively connected to two second rings by a connecting mechanism, and a plurality of elastic rods fixedly connected between the side walls of the two second rings adjacent to each other, the elastic rods being hollow. This invention incorporates a mixing mechanism, in which the bidirectional reciprocating screw rotates, causing the two second rings to intermittently move closer to and farther from each other while rotating. This allows the multiple elastic rods to be intermittently stretched, elongated, and squeezed and folded. This allows the multiple elastic rods to continuously change shape within the body, thereby improving the mixing efficiency of the colored sewage and the decolorizer. However, the photoresistor in this device detects the transmittance of the sewage to light. While color depth does affect transmittance, tiny suspended particles and fiber debris also scatter and absorb light, causing the light intensity detected by the photoresistor to decrease. In actual applications, this combined effect can cause the detection device to deviate from its assessment of the sewage decolorization effect, failing to accurately reflect the actual color removal situation.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 10 The present invention provides a technical solution: a sewage treatment device based on water pollution, comprising a box body 1, a bubble generating device 11 fixedly mounted on the inner wall of the box body 1, a ball-hinged mounting rod 7 provided at the top of the box body 1, an arc-shaped disc 8 fixedly mounted at the bottom of the mounting rod 7, a plurality of barbs 20 provided at the top of the arc-shaped disc 8, and a plurality of water outlet holes 21 provided at the center of the top of the arc-shaped disc 8;

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

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

[0033] See Figure 1 and Figure 2 When textile wastewater needs to be treated, the staff mixes the wastewater with a bleaching agent and pours it into the box 1, and starts the detection component to detect the light transmittance of the wastewater inside the box 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 bleaching agent is added, resulting in insufficient decomposition of the dyeing substances in the wastewater, thereby reducing the light transmittance; second, the fiber impurity content in the wastewater is too high, resulting in a significant decrease in light transmittance.

[0034] At this time, by starting the bubble generating device 11, the bubble generating device 11 continuously releases microbubble groups inside the box 1. After being released, these bubbles will float to the top of the water surface. In the process of floating, they will combine with the fibers suspended in the sewage to form bubble-fiber aggregates. Under the action of buoyancy, the fibers will float to the water surface and float to the liquid surface to form a scum layer. At the same time, the rotating component drives the arc disk 8 to deflect around the ball hinge point. Figure 1 In the initial state, the bottom of the arc-shaped disk 8 is partially immersed in water. When deflection occurs (see Figure 9 ), one side edge of the arc-shaped disc 8 sinks into the water, and the arc-shaped disc 8 is released by rotating the assembly at this time. The arc-shaped disc 8 will reset under the action of gravity. During this process, the sewage and part of the scum layer on the liquid surface will be collected into the arc-shaped disc 8. During the reset process, the sewage collected in the arc-shaped disc 8 will flow on its surface, thereby passing over the barbs 20 on the top of the arc-shaped disc 8, and the fibers will be thickened by the barbs 20 (the barbs 20 can adopt a hook surface or suede surface similar to Velcro), and the residual sewage will flow back into the interior of the box 1 through the water outlet 21. This reciprocating operation is continuously performed to process the fibers in the sewage, thereby completing the dynamic retention and separation of the fibers.

[0035] While the above process is repeated, the arc disk 8 is driven to deflect in different directions by the rotating component, so that a larger range of sewage liquid surface can be cleaned to achieve more efficient separation, and the sewage inside the box 1 is continuously detected by the detection component. When the light transmittance is caused by excessively high fiber content, the detection result of the detection component will be in a fluctuating state. When this fluctuation is at a relatively stable value, the influence of the fiber on the light transmittance of the sewage can be eliminated. At this time, the staff can add an appropriate amount of decolorizing agent to the inside of the box 1.

[0036] Among them, it is worth mentioning that when the arc disk 8 is driven to deflect by the rotating assembly, as shown in FIG. Figure 8As shown, the arc-shaped disc 8 deviates to the right. At this time, the sewage and the scum layer will be pushed by the arc-shaped disc 8 to move toward the inner wall of the box body 1, and the detection component can detect the light transmittance at this location. If the fluctuation value of the light transmittance here is within a stable range, the influence of the fiber on the light transmittance can be ruled out, thereby judging whether the amount of decolorizing agent used is appropriate.

[0037] Furthermore, the rotating assembly includes a rotatable mounting sleeve 10 installed at the bottom center of the box body 1, a fixed shell 30 is fixedly installed on the outer wall of the mounting sleeve 10, a sliding frame 24 that can slide 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, and a plurality of first permanent magnets 22 that can cooperate with the second permanent magnet 23 are fixedly installed on the bottom of the arc disk 8, and when the arc disk 8 is in a horizontal state, one of the first permanent magnets 22 is in contact with the second permanent magnet 23, and when the arc disk 8 is in a horizontal state, at least one first permanent magnet 22 corresponds to the position of 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 is in contact with the second permanent magnet 23. When the arc disk 8 needs to be deflected, the sliding frame 24 is driven by the external driving component to slide inside the fixed shell 30, thereby driving 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, and then drive the arc disk 8 to rotate at the ball hinge point. As the arc disk 8 deflects, its edge gradually sinks into the sewage and begins to take over the sewage and scum layer. As the sliding frame 24 moves a gradually increasing distance, the second 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 is insufficient 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, and at the same time, the external drive component drives the mounting sleeve 10 to rotate a predetermined angle, thereby resetting the sliding frame 24. When the sliding frame 24 resets, it will align with the next first permanent magnet 22 and form a new magnetic attraction pair to prepare for the next deflection.

[0039] Furthermore, the sliding frame 24 is connected to the fixed shell 30 by a second spring 29, and a rotatable screw 25 is installed on the inner wall of the fixed shell 30. A latch 26 is provided through the bottom of the sliding frame 24, and the latch 26 can slide vertically and the lower end can be embedded in the thread groove of the screw 25. The top of the latch 26 is connected to the top of the sliding frame 24 by a first spring 28. The top of the latch 26 is provided with an unlocking inclined surface, and an unlocking rod 27 is provided horizontally through the side wall of the sliding frame 24, and one end of the unlocking rod 27 is in contact with and abuts against the unlocking inclined surface of the latch 26, and the other end of the unlocking rod 27 can be in contact with and abuts against the inner wall of the fixed shell 30. The part of the latch 26 that passes through the bottom of the sliding frame 24 is provided with elastic tiny particles.

[0040] See Figure 3 As can be seen from the above, when the arc disk 8 needs to be offset, the first permanent magnet 22 is driven to move by driving the second permanent magnet 23, thereby completing the deflection of the arc disk 8. When the second permanent magnet 23 needs to be moved, the screw 25 is rotated by the external driving component. At this time, under the action of the first spring 28, the bottom end of the latch 26 is embedded in the thread groove of the screw 25. The rotation of the screw 25 drives the latch 26 and the sliding frame 24 to gradually squeeze the second spring 29 and move away from the mounting sleeve 10, thereby driving the second permanent magnet 23 to move, thereby completing the purpose of offsetting the arc disk 8 through magnetic force.

[0041] As the sliding frame 24 slides, it gradually approaches 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, the unlocking rod 27 will be pushed into the inside of the sliding frame 24, and the sliding frame 24 will come into unlocking contact with the latch 26, thereby driving the latch 26 to move upward and gradually disengage from the thread groove of the screw 25. When the two are completely disengaged, the elastic particles on the outer wall of the latch 26 will be squeezed into the penetration of the sliding frame 24 and organize the latch 26 to reset. At this time, it will quickly reset under the action of the second spring 29. When the sliding frame 24 contacts the left outer wall of the fixed shell 30 under the action of elastic force, the bottom of the latch 26 will be re-embedded in the thread groove of the screw 25 under the action of vibration and the action of the first spring 28, preparing for the next offset of the arc disk 8.

[0042] Furthermore, a limiting tube 4 communicating with the interior of the box 1 is provided at the top of the box body 1, and 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 limiting tube 4 through a first tension spring 5, and the bottom of the sliding rod 6 is connected to the top of the mounting rod 7 through a ball hinge.

[0043] See Figure 2In the previous embodiment, part of the arc disk 8 is always in the liquid surface, and part of the barb 20 is always immersed in water, resulting in that part of the fiber separation in the water is carried out in the water. Due to the lubricating effect of water, the efficiency of the combination of the barb 20 and the fiber is reduced. To solve this problem, when the arc disk 8 is deflected by 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 the arc disk 8 to continue to deflect, the arc disk 8 is reset in the process, and the first tension spring 5 will move the mounting rod 6 through the sliding rod 6. 7 is pulled upward, so that the arc disk 8 is completely separated from the blade. At this time, the barb 20 is exposed to the air, the fiber loses the lubricating effect of water, and the binding force with the barb 20 is significantly improved. At the same time, the sewage in the arc disk 8 quickly flows back to the inside of the box body 1 through the water outlet 21. When the mounting sleeve 10 rotates and the sliding frame 24 is reset, the second permanent magnet 23 corresponds to the next first permanent magnet 22 and attracts it, thereby pulling the first tension spring 5 again, so that the arc disk 8 is immersed in the water again, and the system enters the next cycle.

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

[0045] See Figure 6 The external motor drives the center rod 9 to rotate, thereby driving the second bevel gear 33 to rotate. The engagement of the second bevel gear 33 with the first bevel gear 32 transmits power to the screw 25. The rotation of the screw 25 pushes the pin 26 through the thread groove to produce axial displacement, thereby driving the sliding frame 24 and the second permanent magnet 23 to move, thereby completing the purpose of deflecting the arc disk 8.

[0046] Furthermore, a mounting shell 14 is fixedly installed at the bottom of the box body 1, and the center rod 9 passes through the bottom of the box body 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 center rod 9, and a driven gear 19 meshing with the rotating gear 18 is rotatably installed at the top of the mounting shell 14. The driven gear 19 is also coaxially fixed with a driving member 17, one end of the driving member 17 is an arc-shaped surface, and the other end is a connecting rod shape, and a protrusion 31 is fixedly connected to the connecting rod-shaped top of the driving member 17, and a driving ring 15 is fixedly connected to the outer wall of the mounting sleeve 10. The inner wall of the driving ring 15 has a plurality of arc grooves corresponding to the driving member 17 in a circular array, and a plurality of limiting guide rails 16 are provided at the bottom of the driving ring 15, and the protrusion 31 can be selectively embedded in the limiting guide rail 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 shell 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 member 17 to rotate. The rotation of the driving member 17 causes the arc surface of the driving member 17 to periodically contact and separate with the arc surface groove of the driving ring 15. When the arc surface of the driving member 17 fits with the arc surface groove of the driving ring 15, it limits the driving ring 15 and the mounting sleeve 10 to prevent it from happening. When the arc surface of the driving member 17 is disengaged from the arc groove of the driving ring 15, the protrusion 31 on the top of the other side will be aligned with the limiting guide rail 16 at the bottom of the driving ring 15 and embedded therein, driving the limiting guide rail 16 to rotate, thereby realizing the periodic rotation of the driving ring 15, thereby causing the driving ring 15 to drive the mounting sleeve 10 and the fixed shell 30 to rotate periodically, so as to achieve the above-mentioned purpose of deflecting the arc disk 8 at different angles. This mechanism perfectly realizes the precise control of the "adsorption-separation-discharge" action chain of fiber impurities in the sewage treatment process through mechanical intelligent transmission.

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

[0049] A sealing ring is provided at the contact point between the bottom of the box body 1 and the mounting sleeve 10, which can effectively prevent sewage from penetrating into the rotating parts. The sealing ring is made of fluororubber and forms a double sealing barrier through interference fit, which not only blocks the corrosion of sewage on the bearings, but also avoids transmission jamming caused by the entry of impurities.

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

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

[0052] Furthermore, a plurality of radially distributed flow-guiding ridges are provided at the bottom of the arc-shaped disk 8 .

[0053] See Figure 9 When the arc-shaped disc 8 deviates, the guide ridges at the bottom of the arc-shaped disc 8 will cause the water flow to generate a directional vortex, causing the fiber impurities in the sewage to gather toward the edge of the disc body. Figure 8As shown by the middle arrow, the flow of the water surface can be increased, which not only prevents the scum layer from settling under the arc-shaped plate 8, but also cooperates with the detection component to detect the fiber content in the water.

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

[0055] The detection component realizes real-time monitoring of sewage transmittance through the corresponding arrangement of spotlights 12 and photoresistors 13. The circular array layout of the spotlights 12 forms multi-angle light source coverage, and cooperates with the photoresistors 13 on the side wall of the box 1 to eliminate detection blind spots. By comparing the difference in light intensity attenuation at different positions, it can be determined whether the transmittance is reduced due to insufficient decolorizing agent or excessive fiber, thereby enabling precise adjustment.

[0056] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

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