Description

Technical Field

[0001] This invention relates to the field of water pollution control and treatment technology, and in particular to a wastewater treatment device based on laundry detergent production. Background Technology

[0002] The production of laundry detergent generates a large amount of high-concentration wastewater, mainly from processes such as ingredient mixing, reaction, spray drying, and equipment cleaning. If discharged directly without effective treatment, it will not only cause eutrophication, foam pollution, and ecotoxicity in the receiving water bodies, but also impact the operation of subsequent wastewater treatment plants. Therefore, how to achieve efficient purification and stable compliance of laundry detergent production wastewater has become one of the urgent technical challenges to be solved in the field of water pollution control and treatment.

[0003] In the treatment of wastewater from laundry detergent production, adjusting the pH value from 9-12 to neutral is a crucial step. However, during the neutralization process, laundry detergent wastewater has a strong buffering capacity. Directly adding acid can easily cause the pH to drop momentarily when acid is added, and then rebound back to alkaline after a short pause. This will result in the neutralized wastewater still being alkaline, reducing the neutralization effect. Summary of the Invention

[0004] This invention discloses a wastewater treatment device based on laundry detergent production, aiming to solve the technical problem that during the neutralization process, laundry detergent wastewater has a strong buffering capacity, and direct addition of acid easily leads to a phenomenon where "the pH value drops momentarily when acid is added, and then rebounds to alkalinity after a short pause." This results in the neutralized wastewater remaining alkaline, reducing the neutralization treatment effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wastewater treatment device based on laundry detergent production includes a neutralization tank and a collection tank. An inflow tank is fixedly connected to the top of the collection tank, and a secondary fine adjustment mechanism is provided at equal intervals below the inflow tank. The secondary fine adjustment mechanism includes a diversion cylinder, which is fixedly connected to a fixing hole at the bottom of the inflow tank. A central guide cone is fixedly connected to the inner wall of the diversion cylinder near the top. A diversion hole is annularly opened on the central guide cone near the inner wall of the diversion cylinder. An inner rod is fixedly connected to the inner wall of the diversion cylinder below the central guide cone, and a lifting nozzle is fixedly connected to the end of the inner rod. A flow guide frame is fixedly connected to the top of the lifting nozzle, and a guide is opened on the arc surface of the flow guide frame. The flow channel, the flow guide frame, and the raised nozzle are in a connected state. A ring track is fixedly connected to the outer wall of the flow divider near the bottom, and a driven rotating tooth is slidably connected inside the ring track. A sealing rotating plate is fixedly connected to the bottom of the driven rotating tooth. A through adapter hole is opened at the center of the sealing rotating plate.

During the mixing process, the drive motor is started. The drive motor drives the driven gear to rotate through the active rotating gear, thereby driving each mixing frame to mix and stir the mixture of acidic liquid and wastewater. This makes the neutralization of wastewater and acidic liquid more complete, improves the wastewater neutralization treatment effect, and avoids the situation where the pH drops sharply when acid is added and then rebounds to alkalinity after a short pause.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] The wastewater treatment equipment disclosed in this invention, based on laundry detergent production, is mainly used in the neutralization process. Laundry detergent wastewater has a strong buffering capacity. Directly adding acid can easily cause the pH to drop momentarily when acid is added, and then rebound back to alkalinity after a short pause. This will result in the neutralized wastewater still being alkaline, reducing the neutralization treatment effect.

[0030] Reference Figures 1-10A wastewater treatment device based on laundry detergent production includes a neutralization tank 1 and a collection tank 7. An inlet box 5 is fixedly connected to the top of the collection tank 7, and a secondary fine adjustment mechanism 6 is provided at equal intervals below the inlet box 5. The secondary fine adjustment mechanism 6 includes a diversion cylinder 601, which is fixedly connected to a fixing hole at the bottom of the inlet box 5. A central guide cone 610 is fixedly connected to the inner wall of the diversion cylinder 601 near the top. A diversion hole 615 is annularly opened on the central guide cone 610 near the inner wall of the diversion cylinder 601. An inner rod is fixedly connected to the inner wall of the diversion cylinder 601 below the central guide cone 610, and a lifting nozzle 619 is fixedly connected to the end of the inner rod. A flow guide frame 620 is fixedly connected to the top of the lifting nozzle 619, and a flow guide groove 616 is opened on the arc surface of the flow guide frame 620. The raised nozzle 619 is in a connected state. An annular track 604 is fixedly connected to the outer wall of the splitter tube 601 near the bottom. A driven rotating tooth 607 is slidably connected inside the annular track 604. A sealing rotating plate 618 is fixedly connected to the bottom of the driven rotating tooth 607. A through adapter hole is opened at the center of the sealing rotating plate 618. The raised nozzle 619 is located in the adapter hole.

The active rotating tooth 608 meshes with the driven rotating tooth 607.

[0031] In a specific application scenario, after preliminary neutralization treatment in neutralization tank 1, the laundry detergent wastewater is pumped into collection tank 5 by transfer pump 3. The wastewater entering collection tank 5 then flows into various distribution cylinders 601 for further fine treatment. After entering distribution cylinders 601, the wastewater flows downwards through the distribution holes 615 on the central guide cone 610. Acidic liquid rises through the raised nozzle 619 to the guide frame 620, flowing towards the wastewater along various guide channels 616. The acidic liquid and wastewater layers... Layered mixing ensures full contact between acidic liquid and wastewater, improving the fine neutralization effect. During the mixing process, the drive motor 605 is activated, which drives the driven gear 607 to rotate via the active rotating gear 608. This, in turn, drives each mixing frame 617 to mix and stir the mixture of acidic liquid and wastewater, making the neutralization of wastewater and acidic liquid more thorough, improving the wastewater neutralization treatment effect, and preventing the pH from dropping sharply when acid is added and then rebounding to alkalinity after a short pause.

[0032] Specifically, when the wastewater flows to the bottom of the diversion cylinder 601, it is discharged through the outlet pipe 603. The online pH meter 612 detects its pH value. If the test result is not up to standard, the index valve 602 is closed and the circulation pump 613 is turned on. The circulation pump 613 re-introduces this part of the wastewater into the collection tank 5, repeating the fine adjustment steps to ensure that the finally discharged wastewater is neutralized and treated to meet the standards.

The delivery end of the merging pump 13 is connected to the inside of the connecting main pipe 17 through a pipe. The extraction end of the merging pump 13 is fixedly connected to a merging pipe 12.

[0037] Reference Figures 8-10 In a preferred embodiment, a push cylinder 1002 is fixedly connected to one side of the neutralization tank 1, and an end block 1003 is fixedly connected to the output end of the push cylinder 1002. A traction rope 1005 is fixedly connected to the bottom of the end block 1003. The bottom end of the traction rope 1005 is fixedly connected to the top of the external frame 1007. Two mounting rods 1012 are fixedly connected to the top of the external frame 1007, and the same annular conveying pipe 1004 is fixedly connected to the top of the two mounting rods 1012. A spray hole 1008 is opened on the outer side wall of the annular conveying pipe 1004 facing downward. Fixing plates 1011 are fixedly connected to both sides of the external frame 1007. A stirring motor 1009 is fixedly connected to the top of the two fixing plates 1011. The output shaft of the stirring motor 1009 is fixedly connected to a stirring frame 1006 through a coupling.

[0038] Specifically, after the wastewater is introduced into the neutralization tank 1, during the initial neutralization treatment, the cylinder 1002 is pushed to move back and forth, and the fixed sliding sleeve 1010 is driven to slide in the fixed guide rail 1001 by the traction rope 1005. The inlet pump 15 is started, and the inlet pump 15 introduces the acidic liquid into the annular conveying pipe 1004, which is then sprayed into the wastewater through the spray hole 1008. During this process, the stirring motor 1009 is started, and the stirring motor 1009 drives the stirring frame 1006 to fully stir the wastewater and acidic liquid, accelerating the contact and neutralization between the two. The fixed sliding sleeve 1010 moves back and forth on the fixed guide rail 1001 to avoid the local introduction of acidic liquid and cause the wastewater in that area to become too acidic. At the same time, the stirring frame 1006 moves back and forth with the fixed sliding sleeve 1010 to achieve stirring treatment at various positions inside the neutralization tank 1, so that the acidic liquid and wastewater are fully neutralized and the uneven neutralization in some areas is avoided.

[0039] It should be noted that when the mixing frame 1006 reciprocates with the fixed sliding sleeve 1010, the mixing frame 1006 is in a high-speed rotation state. During its rotation, it drives the surrounding wastewater to flow rapidly, thereby driving the fixed shaft 16 to rotate. The auxiliary rotating blade 14 works in conjunction with the mixing frame 1006 to better accelerate the flow of wastewater.

[0040] Reference Figure 1 and Figure 8In a preferred embodiment, a limiting guide rail 2 is fixedly connected to one side of the neutralization pool 1, and a limiting slider 23 is slidably connected inside the limiting guide rail 2. A base plate 22 is fixedly connected to the top of the limiting slider 23, and a fixed pump frame 21 is fixedly connected to the top of the base plate 22. An inlet pump 15 is fixedly connected inside the fixed pump frame 21.

[0041] Reference Figure 8 and Figure 9 In a preferred embodiment, the extraction end of the inlet pump 15 is fixedly connected to an extraction pipe 11, and the delivery end of the inlet pump 15 is fixedly connected to a telescopic connecting pipe 25. One end of the telescopic connecting pipe 25 is inserted into the interior of the annular conveying pipe 1004. The bottom plate 22 and the end block 1003 are fixedly connected to the same connecting rod. The outer wall of the connecting rod is fixedly connected to a locking block 24, and the telescopic connecting pipe 25 passes through the locking block 24.

[0042] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the bottom inner wall of the neutralization tank 1 is connected to fixed shafts 16 at equal intervals via bearings, and each fixed shaft 16 is fixedly connected to an auxiliary rotating blade 14 on its outer side wall. The auxiliary rotating blade 14 is located at both ends of the fixed guide rail 1001. A drain hole is opened on one side of the neutralization tank 1, and a drain pipe 8 is fixedly connected inside the drain hole. A pipe valve 9 is connected to the outer side wall of the drain pipe 8 via a flange.

[0043] Working principle: During use, wastewater is pumped into neutralization tank 1, then the inlet pump 15 is started, which introduces the acidic liquid into the annular conveying pipe 1004 and sprays it into the wastewater through the nozzle 1008. During this process, the stirring motor 1009 is started, which drives the stirring frame 1006 to fully stir the wastewater and acidic liquid, accelerating their contact and neutralization. During the operation of the inlet pump 15 and the stirring motor 1009, the cylinder 1002 is pushed to move back and forth, which drives the fixed sliding sleeve 1010 in the fixed guide rail 1001 through the traction rope 1005. The sliding motion of the mixing frame 1006, along with the reciprocating motion of the fixed sliding sleeve 1010, causes the mixing frame 1006 to rotate at high speed. This rotation drives the surrounding wastewater to flow rapidly, which in turn causes the fixed shaft 16 to rotate. The auxiliary vane 14, in conjunction with the mixing frame 1006, further accelerates the flow of wastewater. Once the wastewater in the neutralization tank 1 is initially neutralized, the transfer pump 3 is started. The transfer pump 3 guides the wastewater from the neutralization tank 1 into the collection tank 5. Wastewater enters each of the distribution cylinders 601. After entering the distribution cylinder 601, the wastewater flows downwards through the distribution holes 615 on the central guide cone 610. Acidic liquid rises through the raised nozzle 619 to the guide frame 620, and flows towards the wastewater along each guide channel 616. The acidic liquid and wastewater are mixed layer by layer, achieving full contact between the acidic liquid and wastewater. During the mixing process, the drive motor 605 is started. The drive motor 605 drives the driven gear 607 to rotate through the active rotating gear 608, thereby driving each mixing frame 617 to mix the acidic liquid and wastewater. The water mixture is stirred to ensure more thorough neutralization of the wastewater and acidic liquid. When the wastewater flows to the bottom of the distribution cylinder 601, it is discharged through the outlet pipe 603. The online pH meter 612 detects its pH value. If the test result is not up to standard, the index valve 602 is closed and the circulation pump 613 is turned on. The circulation pump 613 re-introduces this part of the wastewater into the collection tank 5 to repeat the fine adjustment steps. The wastewater that meets the standard is discharged through the outlet pipe 603 into the collection tank 7. The collection pump placed in the collection tank 7 discharges and collects the finely adjusted wastewater.
