[0002] Anthraquinone dyes are widely used in the textile and printing industries due to their excellent dyeing performance and color brightness. However, a large amount of wastewater is generated during the production of anthraquinone dyes. This type of wastewater is complex in composition, containing high concentrations of anthraquinone dye molecules, additives, and other organic and inorganic pollutants.

[0003] Traditional anthraquinone dye wastewater decolorization treatment technologies face many challenges. Physical treatment methods, such as adsorption, can effectively remove some dyes, but the regeneration and replacement of adsorbents are costly, and the adsorption capacity is limited. Chemical treatment methods, such as oxidation, can destroy the color groups of dyes to achieve decolorization, but often require large amounts of oxidizing agents, which can easily cause secondary pollution, and the treatment effect is greatly affected by wastewater quality and reaction conditions.

[0004] With the increasing strictness of environmental protection requirements, the treatment of anthraquinone dye wastewater not only needs to achieve efficient decolorization, but also needs to meet the requirements of reducing treatment cost, reducing secondary pollution, and improving treatment stability. The existing single treatment technology cannot meet these comprehensive needs.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0036] The above-mentioned water inlet one 13 can let wastewater directly enter processing layer two 30, when processing layer one 11 and processing layer two 30 are all filled, wastewater stops entering.

[0037] Therefore, rotating assembly 3 in the present scheme can control filter plate one 23 cross-moving by cooperating with each component, change the aperture of filter plate one 23, avoid blockage, also can mix and stir wastewater, generate current in mixing process, and the anthraquinone substance with electric charge is moved to it by electric field force, and the color factor in wastewater is adsorbed, cleaning assembly 5 can also be used to clean metal net 42, the adsorption capacity of color factor in anthraquinone dye wastewater is enhanced as a whole.

[0038] In the embodiment, on the basis of the first embodiment, the adsorption capacity of color factor in anthraquinone dye is improved.

[0039] Referring to Figures 2-4 , filter assembly 2 also includes fixed seat 21 fixedly connected with the inner surface of processing layer one 11, sliding groove 22 is formed on the both sides of the inner surface of fixed seat 21, the horizontal positions of the two sliding grooves 22 are staggered up and down, the inner surfaces of the two sliding grooves 22 are slidably connected with filter plate one 23, two limiting seats 24 are fixedly connected with the lower ends of the two filter plates one 23, and the inner surfaces of the four limiting seats 24 are slidably connected with limiting block one 25.

[0040] The lower end of the two middle limiting blocks 25 is rotationally connected with L-shaped connecting rod two 27, the end of the two L-shaped connecting rod two 27 close to each other is fixedly connected with arc-shaped tooth 271, the outer surfaces of the two arc-shaped teeth 271 are meshingly connected with each other, the lower side of the left limiting block one 25 is rotationally connected with limiting rod 28, the end of the limiting rod 28 away from the limiting block one 25 is rotationally connected with the lower end of the fixed seat 21, the lower side of the right limiting block one 25 is rotationally connected with L-shaped connecting rod one 26, the end of the L-shaped connecting rod one 26 away from the limiting block one 25 is rotationally connected with the lower end of the fixed seat 21, and the inner surface of the processing layer one 11 and located at the lower side of the fixed seat 21 is provided with filter plate two 29.

[0041] Further, when the angle of the L-shaped connecting rod one 26 changes, the right filter plate one 23 will be driven to move to the right, so that the angle of the two L-shaped connecting rod two 27 also changes, the two arc-shaped teeth 271 mesh with each other, so that the left filter plate one 23 and the right filter plate one 23 always maintain opposite motion trajectories and cross sliding, but they will not be completely separated and will always be in contact.

[0042] The two filter plate one 23 can continuously and effectively intercept the suspended solids, larger particles and other impurities in the anthraquinone dye wastewater, and the stable filtering effect provides relatively stable water inlet conditions for the subsequent treatment steps, thereby reducing the load of the subsequent treatment steps.

[0043] Further, the pore size of the two filter plate one 23 will also be staggered back and forth during the cross sliding process, so that the pore size changes, avoiding the problem that the filter plate one 23 with fixed pore size is easy to block, and different size particles can pass through the filter plate one 23 more reasonably, and will not continuously accumulate at the same position, greatly reducing the risk of the filter plate one 23 being blocked, ensuring that the filtering process continues and stabilizes, prolonging the service life of the filter plate one 23, and reducing the frequency and cost of equipment maintenance.

[0044] Further, the filter plate two 29 in the above is a polyester fiber filter plate, which effectively intercepts fine particles and suspended solids in wastewater, further purifies wastewater, removes fine impurities that cannot be completely removed by the filter plate one 23, and improves the effect of pretreatment.

[0045] Referring to Figure 2 、 Figures 5-9 , the rotating assembly 3 further comprises a mounting seat 31 fixedly connected with the upper end of the outer shell 1, a motor 32 fixedly installed at the upper end of the mounting seat 31, a belt pulley one 33 fixedly connected with the output end of the motor 32, a belt 34 woundly connected with the outer surface of the belt pulley one 33, a belt pulley two 35 woundly connected with the inner surface of the belt 34, a one-way shaft one 351 rotationally connected with the inner surface of the belt pulley two 35, and a belt pulley three 341 woundly connected with the inner surface of the belt 34.

[0046] Further, the unidirectional shaft one 351 in the above can only rotate in one direction, when the pulley one 33 rotates clockwise, the pulley two 35 will drive the unidirectional shaft one 351 to rotate, thereby driving the rotating disc 36 to rotate, while when the pulley one 33 rotates counterclockwise, the pulley two 35 rotates, the unidirectional shaft one 351 remains stationary, so at this time the rotating disc 36 also remains stationary.

[0047] The lower end of the pulley two 35 is fixedly connected with the rotating disc 36, one side of the lower end of the rotating disc 36 is fixedly connected with the protrusion 361, the outer surface of the protrusion 361 is slidably connected with the annular seat 37, the left and right two ends of the annular seat 37 are fixedly connected with the movable rod 38, the outer surfaces of the two movable rods 38 are slidably connected with the limiting block two 39, the upper ends of the two limiting block two 39 are fixedly connected with the inner surface of the outer shell 1, the ends of the two movable rods 38 away from each other are fixedly connected with the sliding block 310, the left end of the left sliding block 310 is fixedly connected with the sliding rod 311, the outer surface of the sliding rod 311 is slidably connected with the inner surface of the outer shell 1, and the left end of the sliding rod 311 is in contact with the end of the L-shaped connecting rod one 26 away from the limiting block one 25.

[0048] The protrusion 361 in the above is located on one side of the rotating disc 36, when the rotating disc 36 rotates, it can drive the protrusion 361 to slide in the annular seat 37 continuously, so that the annular seat 37 drives the two movable rods 38 to move.

[0049] Further, the limiting block two 39 in the above can limit the two movable rods 38, so that they can only move left and right in parallel, thereby driving the sliding block 310, the connecting block 312 and the filter plate three 315 to move reciprocatingly.

[0050] The lower ends of the two sliding blocks 310 are fixedly connected with the connecting block 312, the upper side of the inner surface of the processing layer two 30 is fixedly connected with the fixed plate 313, the lower ends of the two sliding blocks 310 are slidably connected with the upper end surface of the fixed plate 313, the outer surface of the fixed plate 313 is symmetrically provided with two through grooves 314, the outer surfaces of the two connecting blocks 312 are slidably connected with the two through grooves 314, and the lower ends of the two connecting blocks 312 are fixedly connected with the filter plate three 315.

[0051] The filter plate three 315 in the above is a hydrophilic porous material, which has a certain filtering effect itself, can intercept part of small particles and impurities, and can stir the wastewater by reciprocating movement, so that the flocculant, oxidant, anthraquinone dye molecules and the like in the wastewater are fully mixed, the chemical reaction is promoted, the flocculant is more uniformly contacted with the suspended particles, a larger and denser floe is formed, the oxidant is more fully reacted with the dye molecules, the decolorization rate is improved, and the reaction efficiency and treatment effect are improved.

[0052] Meanwhile, the connecting block 312 can continuously stir the wastewater during the movement process, and the wastewater is hit to the metal nets 42 on both sides, so that the wastewater is fully contacted with the metal nets 42, and the opportunity of adsorption and removal of the anthraquinone substances by the metal nets 42 is increased.

[0053] Referring to Figures 9-10 The power generation assembly 4 further comprises two fixed blocks one 41 fixedly connected with the inner surfaces of the two sides of the processing layer two 30, the lower ends of the two fixed blocks one 41 are both provided with two metal nets 42, one side of the two metal nets 42 on the same side and close to each other is provided with a graphene 43, the outer surfaces of the metal nets 42 on the same side and close to one end of the connecting block 312 are provided with two piezoelectric ceramics 44, one side of the two connecting blocks 312 and away from each other is fixedly connected with two fixed blocks two 45, the left ends of the two fixed blocks two 45 on the same side are both fixedly connected with an extension rod 46, the outer surfaces of the two extension rods 46 on the same side are both sleeved with a spring 47, the left ends of the two extension rods 46 on the same side are both fixedly connected with a knocking block 48, and the outer surfaces of the two knocking blocks 48 on the same side are both in contact with the two piezoelectric ceramics 44 on the same side.

[0054] Further, the piezoelectric ceramic 44 in the above is a conventional technology in the prior art, which is a functional ceramic material capable of realizing the mutual conversion between mechanical energy and electrical energy, and its working principle is based on the piezoelectric effect, which is as follows: when an external force such as pressure, tension, etc. is applied to the piezoelectric ceramic 44, the crystal structure inside the ceramic will deform, resulting in the separation of positive and negative charge centers, thereby generating equal and opposite charges on the two opposite surfaces of the ceramic, forming an electric field, and realizing the conversion of mechanical energy to electrical energy. In the above anthraquinone wastewater treatment device, the knocking block 48 reciprocally moves with the filter plate three 315 to continuously touch the piezoelectric ceramic 44, which will cause the piezoelectric ceramic 44 to generate pressure changes and in turn generate electrical energy to be transmitted to the metal net 42. In the anthraquinone wastewater treatment, the main use is the positive piezoelectric effect of the piezoelectric ceramic 44, which generates electrical energy through external mechanical force to provide current for the metal net 42 and the graphene 43 to enhance the adsorption capacity of the color factor.

[0055] The graphene 43 is located at the middle position of the metal net 42, the metal net 42 has good mechanical strength and stability, and can provide support and protection for the graphene 43 in the middle, prevent the graphene 43 from being damaged or deformed due to water flow impact, stirring and other factors during the wastewater treatment process, and the piezoelectric ceramic 44 can transmit electrical power to the metal net 42, so that the metal net 42 forms an electric field environment. In this electric field, the anthraquinone substances with electric charge will be affected by the electric field force and move to the charged metal net 42, and the graphene 43 in the middle can adsorb and interact with these substances, and the two work together to strengthen the removal effect of the anthraquinone substances in the wastewater, and further improve the treatment efficiency and treatment capacity.

[0056] Further, the surface of the knocking block 48 is provided with rubber pads to avoid damage to the piezoelectric ceramic 44 during extrusion.

[0057] The spring 47 can provide a buffering force to the knocking block 48.

[0058] It should be noted that the piezoelectric ceramic 44 is connected to the metal mesh 42 by conductive glue.

[0059] Referring to Figure 6 、 Figure 7 and Figure 10 , the cleaning assembly 5 includes a one-way shaft two 50 rotatably connected to the inner surface of the belt pulley three 341, two reciprocating rods 51 rotatably connected to the inner surface of the treatment layer two 30, and a lifting block 52 slidably connected to the outer surface of each of the two reciprocating rods 51. The outer surfaces of the two lifting blocks 52 are slidably connected to the inner surface of the treatment layer two 30. The upper end of the left reciprocating rod 51 is fixedly connected to the inner surface of the one-way shaft two 50, and the upper end of the right reciprocating rod 51 is drivingly connected to the upper end of the left reciprocating rod 51 through a belt transmission mechanism 53.

[0060] Further, the one-way shaft two 50 can only rotate in one direction. When the belt pulley one 33 rotates counterclockwise, the belt 34, the belt pulley two 35, and the belt pulley three 341 will rotate counterclockwise together, thereby driving the one-way shaft two 50 and the reciprocating rod 51 to rotate. When the belt pulley one 33 rotates clockwise, the belt 34, the belt pulley two 35, and the belt pulley three 341 will rotate clockwise together, but the one-way shaft two 50 and the reciprocating rod 51 remain stationary.

[0061] The reciprocating rod 51 is a ball screw mechanism in the prior art. When the reciprocating rod 51 rotates counterclockwise with the one-way shaft two 50, the lifting block 52 can move up and down reciprocally, thereby cleaning the surface of the metal mesh 42 to prevent it from being clogged by accumulated pollutants.

[0062] Therefore, when the motor 32 controls the belt pulley one 33 to rotate clockwise, a plurality of structures driven by the rotating disc 36 can be used to stir and filter the wastewater. When the motor 32 controls the belt pulley one 33 to rotate counterclockwise, the above structures remain stationary, but the lifting block 52 can clean the metal mesh 42.

[0063] Referring to Figure 2 and Figure 11 , the drainage assembly 6 includes a water suction pump one 61 fixedly installed on the bottom wall of the inner surface of the treatment layer two 30. The output end of the water suction pump one 61 is fixedly connected to a water pipe one 62, and the end of the water pipe one 62 away from the water suction pump one 61 extends into the inside of the sediment tank 71.

[0064] The inner surface of the back wall of the treatment layer two 30 is fixedly installed with a water suction pump two 63, the output end of the water suction pump two 63 is fixedly connected with a water pipe two 64, one end of the water pipe two 64 away from the water suction pump two 63 is fixedly connected with the outer surface of the water pipe one 62, the inside of the water pipe one 62 close to the connection position of the water pipe two 64 is provided with a one-way valve one 621, and the inside of the water pipe two 64 close to the connection position of the water pipe one 62 is provided with a one-way valve two 641.

[0065] Further, the water suction pump two 63 can suck the wastewater on the upper layer and transport it to the sediment tank 71 for sedimentation treatment in the treatment layer three 7, and when the wastewater and impurities at the bottom of the treatment layer two 30 need to be discharged, the water suction pump one 61 can be directly used to suck the water, and then the water is discharged through the drain at the bottom of the sediment tank 71.

[0066] The one-way valve two 641 and the one-way valve one 621 are both only used for outward discharge and cannot be used for inward water inflow, so that when the water suction pump one 61 and the water suction pump two 63 are used respectively, the wastewater cannot enter another pipeline through the position connection between the water pipe one 62 and the water pipe two 64.

[0067] Further, in actual use, the flow route of the dye wastewater is as follows:

[0068] The wastewater enters the inside of the treatment layer one 11 through the feed inlet 12, in this process, the wastewater is preliminarily filtered through the filter plate one 23 and the filter plate two 29, and then enters the treatment layer two 30 through the water inlet one 13, when the treatment layer one 11 and the treatment layer two 30 are fully filled, the wastewater stops entering, then the oxidant is poured into the shell body 1, the color-developing group of the anthraquinone dye is destroyed, the color of the anthraquinone dye is lightened or disappeared, the structure of the dye molecule is fundamentally changed, the decolorization purpose is achieved, then the wastewater is subjected to stirring and adsorption treatment in the treatment layer two 30, after the treatment, the water suction pump two 63 is started, the water suction pump two 63 transfers the wastewater on the upper side to the treatment layer three 7, the flocculant is placed in the treatment layer three 7, the treatment layer three 7 is slowly filled with the wastewater, in the process, the flocculent in the wastewater is precipitated into the sediment tank 71, and the water on the upper side is relatively clean and can be discharged from the overflow port 72 to the disinfection layer 8 for subsequent disinfection treatment, when the wastewater and the precipitate remaining in the treatment layer two 30 and the sediment tank 71 need to be discharged, the water suction pump one 61 is started, the water suction pump one 61 starts to suck the water from the bottom of the treatment layer two 30, and then discharges the water from the electric valve at the bottom of the sediment tank 71.

[0069] When the wastewater is treated, the motor 32 is started, the motor 32 drives the belt pulley one 33, the belt 34, the belt pulley two 35 and the belt pulley three 341 to rotate clockwise, drives the one-way shaft one 351 and the rotating disc 36 to rotate, at this time the one-way shaft two 50 is static, in the rotating process, the rotating disc 36 can drive the protruding block 361 to slide in the annular seat 37 constantly, the annular seat 37 drives the two movable rods 38 to move left and right, thereby drives the sliding rod 311, the two sliding blocks 310, the connecting block 312 and the filter plate three 315 to move reciprocatingly, wherein the left sliding block 310 will intermittently touch the L-shaped connecting rod one 26 in the process of driving the sliding rod 311 to move to the left side, the angle of the L-shaped connecting rod one 26 changes, thereby drives the right filter plate one 23 to move to the right side, further drives the angle of the two L-shaped connecting rod two 27 to change, the two arc-shaped teeth 271 mesh with each other, the left filter plate one 23 and the right filter plate one 23 present opposite motion tracks, reciprocate crossly, intercept the suspended solids, larger particles and impurities in the wastewater of the anthraquinone dye wastewater, then the wastewater passes through the filter plate two 29 for secondary filtration, then enters the treatment layer two 30 from the water inlet one 13;

[0070] Synchronously, the sliding block 310 also drives the filter plate three 315 to stir the wastewater when moving left and right, constantly hits the wastewater to the graphene 43 on both sides, and the filter plate three 315 also intermittently generates pressure on the piezoelectric ceramic 44 through the extension rod 46, the spring 47 and the knocking block 48 in the reciprocating movement process, so that the piezoelectric ceramic 44 generates current and transmits to the metal mesh 42, so that the metal mesh 42 forms an electric field environment, in this electric field, the anthraquinone substance with electric charge moves to the charged metal mesh 42 under the action of electric field force, at the same time, the graphene 43 in the middle can adsorb and interact with these substances, which strengthens the removal effect of anthraquinone substances in the wastewater;

[0071] Then let the water in the treatment layer two 30 be static for a period of time, the impurities are precipitated at the bottom, at this time the water suction pump two 63 is started, so that it sucks the wastewater in the upper layer into the treatment layer three 7 for further precipitation treatment, then the water gate at the feeding port 12 can also be opened, continue to fill the wastewater into the treatment layer one 11 and the treatment layer two 30, cycle this step;

[0072] After the wastewater in the treatment layer three 7 is static, the flocculent material is precipitated in the sedimentation tank 71, the water in the upper layer is relatively clean, the relatively clean water directly overflows from the overflow port 72 and enters the disinfection layer 8 for disinfection treatment.

[0073] When cleaning the inside of the device, the motor 32 can be controlled to reverse, and when the pulley one 33 rotates counterclockwise, the belt 34, the pulley two 35 and the pulley three 341 rotate counterclockwise together, thereby driving the one-way shaft two 50 and the reciprocating rod 51 to rotate, making the lifting block 52 move up and down, cleaning the surface of the metal mesh 42, and starting the water suction pump one 61 to suck water from the bottom of the processing layer two 30, and finally discharging from the electric valve at the bottom of the sediment tank 71.

[0074] Therefore, the rotating assembly 3 can drive the two filter plates one 23 to cross reciprocate, filter the larger particles in the anthraquinone wastewater, avoid the problem of easy blockage of the filter plate one 23 with a fixed pore size, and also make the filter plate three 315 knock the wastewater to both sides, and simultaneously drive the knocking block 48 to apply pressure to the piezoelectric ceramic 44, provide current for the metal mesh 42 and graphene 43 to enhance the adsorption capacity of the color factor in the anthraquinone dye wastewater, and also use the reverse of the motor 32 to clean the metal mesh 42 through the cleaning assembly 5, thereby enhancing the removal effect of anthraquinone substances in the wastewater, and further improving the treatment efficiency and treatment capacity of the wastewater.
