Description

Technical Field

[0001] This utility model relates to the field of waste liquid treatment technology, specifically a device for the on-site harmless disposal of chemical residual waste liquid. Background Technology

[0002] Traditional treatment methods require collecting waste liquids and transporting them to centralized treatment plants. During transportation, secondary pollution may occur due to leaks or container damage, especially for highly toxic, flammable, and explosive waste liquids, where the risks are even more pronounced. Therefore, in contrast, the on-site immediate treatment model fundamentally avoids the drawbacks of traditional transportation by deploying on-site treatment equipment: there is no need to wait for transportation scheduling, the storage time of waste liquids is greatly shortened, and the problem of compositional complexity caused by storage is effectively avoided; the equipment can be directly adapted to front-line scenarios such as chemical industrial park production workshops, scientific research laboratories, and oilfield drilling platforms, achieving seamless connection between waste liquid generation and treatment, reducing environmental risks while significantly optimizing enterprise treatment costs.

[0003] Chinese patent discloses a chemical waste liquid purification and treatment device (authorization announcement number CN213433808U), comprising a waste liquid treatment tank and a gas purification tank. One end of the waste liquid treatment tank is fixedly connected to one end of the gas purification tank. A booster pump is fixedly installed on one side of the lower end of the waste liquid treatment tank, and a booster pipe is fixedly installed on the top of the booster pump. The end of the booster pipe away from the booster pump is connected to the inside of the waste liquid treatment tank through an embedded part on the upper end of the waste liquid treatment tank. The booster pump is located on the side of the waste liquid treatment tank away from the gas purification tank. A connecting pipe and a feed inlet are embedded in the top of the waste liquid treatment tank. When using the above device to treat waste liquid, due to the large number of pollutants in the waste liquid and its strong corrosiveness, and the connection between the booster pump and the pipeline... Furthermore, the internal components of booster pumps are prone to scaling and corrosion, leading to aging of seals, rusting of metal, and loosening, resulting in waste liquid leakage. Once leakage occurs, it not only reduces the efficiency of waste liquid treatment but may also pollute the surrounding environment and even threaten the safety of operators. Moreover, the impeller, pump casing, and other components inside the booster pump will gradually become thinner and damaged due to long-term erosion by corrosive waste liquid. At the same time, particulate pollutants in the waste liquid will continuously accumulate inside the pump body, causing scouring and wear during liquid flow, resulting in damage to the internal structure of the pump body and affecting the normal operation of the waste liquid treatment device. Therefore, this utility model provides an on-site harmless disposal device for chemical residual waste liquid to solve the above-mentioned problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 In this embodiment of the invention, a device for the on-site harmless treatment of chemical residual waste liquid includes a filter tank 1. The filter tank 1 uses a built-in multi-layer filter screen and activated carbon adsorption layer to pre-treat the waste liquid, filtering out particulate matter and effectively removing suspended particulate matter and large molecular impurities, providing pretreatment assurance for subsequent treatment processes. A neutralization reactor 2 for adjusting the pH of the waste liquid is fixedly connected to a booster pump via a pipeline on one side of the filter tank 1. A pH adjuster is added to the neutralization reactor 2 to adjust the pH of the waste liquid, controlling its pH and improving reaction efficiency. The end of the neutralization reactor 2 furthest from the filter tank 1 is fixedly connected to the booster pump via a pipeline for adjusting the pH of the waste liquid. The oxidation reaction tower 3 decomposes organic matter. Inside the oxidation reaction tower 3, the organic matter in the waste liquid is catalyzed by reasonable temperature control, which efficiently degrades the organic pollutants in the waste liquid into small molecules or completely mineralizes them, effectively removing the organic matter in the waste liquid. The end of the oxidation reaction tower 3 away from the neutralization reactor 2 is fixedly connected to a membrane separation purification box 4 for secondary filtration of the waste liquid through a pipeline and a booster pump. The membrane separation purification box 4 integrates ultrafiltration membrane and reverse osmosis membrane to perform dual filtration of the waste liquid, effectively intercepting large molecular organic matter and colloidal substances, and removing dissolved pollutants and ionic substances, so that the treated water quality meets the national discharge standards and can be directly reused or safely discharged, realizing the thorough purification and resource utilization of the waste liquid.

[0024] The end of the filter tank 1 furthest from the neutralization reactor 2 is fixedly connected to a booster pump 5 via a pipeline for pressurizing the waste liquid. The booster pump 5 stably delivers the pretreated waste liquid into the filter tank 1. Both ends of the booster pump 5 are rotatably connected to a cleaning structure 6 for removing deposits inside the booster pump 5. The cleaning structure 6 removes the deposits inside the pump, reducing the energy consumption increase caused by scaling, while ensuring the working efficiency of the booster pump 5 and ensuring the stable and reliable operation of the device.

[0025] Please see Figures 1-3A protective box 501 for protecting the outer wall of the booster pump 5 is fixedly installed on the outer wall of the booster pump 5. The cleaning structure 6 is rotatably connected to the inner cavity of the protective box 501. Specifically, a box door 502 is rotatably connected inside the protective box 501 through a rotating shaft. A sealing strip is fixedly installed at one end of the box door 502 near the protective box 501. The box door 502 cooperates with the protective box 501 to isolate the booster pump 5 and the cleaning structure 6 from the corrosion of the external environment, effectively extending the service life of the booster pump 5 and the cleaning structure 6.

[0026] Please see Figures 4-5 The cleaning structure 6 includes a docking cylinder 601, which is rotatably connected to the inner cavity of the protective box 501. There are two docking cylinders 601, which are located at both ends of the booster pump 5. Rotary blades 602 for removing attachments are rotatably connected to the inner cavity of the docking cylinder 601. Specifically, there are six rotating blades 602, which are all rotatably connected to the inner cavity of the docking cylinder 601 and fit against the inner wall of the docking cylinder 601. The inner diameter of the docking cylinder 601 is the same as the inner diameter of the port of the booster pump 5. When the rotating blades 602 gradually enter the port of the booster pump 5 during rotation, they can pry up the attachments at both ends of the booster pump 5 to facilitate subsequent cleaning work.

[0027] Please see Figures 4-5The inner cavity of the docking cylinder 601 is rotatably connected to a rotating shell 603 for driving the rotating blade 602 to rotate and move. The outer wall of the rotating shell 603 is fitted to the inner wall of the docking cylinder 601. Multiple toothed slots 604 are provided on the outer wall of the rotating shell 603 and are threaded onto the outer wall of the rotating shell 603. The inner cavity of the docking cylinder 601 is rotatably connected to a gear 605 for driving the rotating shell 603 to rotate and move. The angle of the gear 605 is tilted according to the arrangement of the toothed slots 604. Specifically, two gears 605 are provided and rotatably connected to the top and bottom of the rotating shell 603. Both gears 605 are hinged to the toothed slots 604. The inner cavity of the docking cylinder 601 has two sets of annular grooves 608. A motor 609 for driving the gear 605 to rotate is fixedly installed in the inner cavity of each set of annular grooves 608. The output shaft of motor 609 is fixedly connected to gear 605. When motor 609 drives gear 605 to rotate, gear 605 pushes rotating shell 603 and rotating blade 602 to rotate through threaded tooth block slots 604, and gradually moves to one side. More specifically, the inner cavity of docking cylinder 601 is provided with a circular sliding groove 606 for limiting rotating shell 603. Six sliding blocks 607 are slidably connected to the inner cavity of circular sliding groove 606, and the six sliding blocks 607 are evenly distributed on the outer wall of rotating shell 603. All six sliding blocks 607 are fixedly connected to rotating shell 603. When rotating shell 603 rotates and moves, it drives the six sliding blocks 607 to slide in the inner cavity of circular sliding groove 606, so that circular sliding groove 606 limits the range of movement of rotating shell 603 and prevents rotating shell 603 from leaving the inner cavity of docking cylinder 601.

[0028] Please see Figures 4-5A fixed shell 611 is rotatably connected to the inner cavity of the rotating shell 603. The fixed shell 611 is fixedly connected to the inner cavity of the rotating shell 603, and the outer wall of the fixed shell 611 fits against the inner cavity of the rotating shell 603. The fixed shell 611 is fixedly connected to the inner cavity of the docking cylinder 601. An angled nozzle 610 for removing deposits from the inside of the booster pump 5 is fixedly installed on the inner wall of the fixed shell 611. The angled nozzle 610 applies high-pressure water to the gap between the pried-up deposits and the inner wall of the booster pump 5, allowing the water flow to better penetrate the deposits through the gaps, thereby improving the removal effect. A water supply pipe 612 for water supply is fixedly installed in the inner cavity of the docking cylinder 601. Specifically… A booster pump for increasing water flow velocity is fixedly installed in the inner cavity of the docking cylinder 601. A special-shaped connecting pipe 613 is fixedly connected to the top of the booster pump. The booster pump is fixedly connected to the angled nozzle 610 through the special-shaped connecting pipe 613. The top of the water supply pipe 612 is fixedly connected to the bottom of the booster pump and extends continuously and is fixedly connected to the top of the inner cavity of the protective box 501 to facilitate connection with other external water sources. Specifically, a telescopic pipe 614 for discharging water and attached substances is fixedly connected to the end of another rotating shell 603 away from the booster pump 5. The telescopic pipe 614 extends continuously and is fixedly connected to the bottom of the inner cavity of the protective box 501 to facilitate the discharge of used water and particles.

[0029] Please see Figure 3 and Figures 6-7 A connecting cylinder 615 for connecting the filter tank 1 and the booster pump 5 is fixedly connected below the connecting cylinder 601. The number of connecting cylinders 615 is the same as that of the connecting cylinder 601, and the positions of the connecting cylinders 615 and the connecting cylinder 601 correspond. Specifically, the inner cavity of the protective box 501 is rotatably connected to a roller 616 for driving the connecting cylinders 601 and 615 to rotate via a bearing. The outer wall of the roller 616 is fixedly connected to a connecting rod 617 for connecting the connecting cylinders 601 and 615, and the connecting cylinders 601 and 615 are fixedly connected to the top and bottom of the connecting rod 617, respectively. The inner cavity of the protective box 501 is fixedly connected to a connecting rod 617 for driving the connecting cylinders 601 and 615 to rotate. The motor 618 rotates the rod 617. The output shaft of the motor 618 is rotatably connected to the belt 619 via the drive wheel. The outer wall of the connecting rod 617 is rotatably connected to the inner cavity of the belt 619 via the driven wheel. Thus, the motor 618 rotates 180° each time, causing the belt 619 to drive the connecting rod 617 to rotate. This switches the docking cylinder 601 and the connecting cylinder 615. When the docking cylinder 601 is at both ends of the booster pump 5, the inner cavity of the booster pump 5 is cleaned. Conversely, when the connecting cylinder 615 is at both ends of the booster pump 5, the waste liquid enters the booster pump 5 through the connecting cylinder 615, allowing the booster pump 5 to work normally.

[0030] Specifically, the inner cavity of the protection box 501 is rotatably connected to an upper arc-shaped plate 620 via bearings. Below the upper arc-shaped plate 620, a lower arc-shaped plate 621 is provided. Both the upper arc-shaped plate 620 and the lower arc-shaped plate 621 have two rotatably distributed connections to both ends of the booster pump 5. The ends of the two lower arc-shaped plates 621 closest to the inner wall of the protection box 501 are rotatably connected to the inner cavity of the protection box 501 via rotating rods. The ends of the upper arc-shaped plate 620 and the lower arc-shaped plate 621 furthest from each other are rotatably connected via driven wheels to drive the upper arc-shaped plate 620 and the lower arc-shaped plate 621. 21. Two rotating belts 622 are rotatably connected to rollers 616. When the rollers 616 rotate and switch the docking cylinder 601 and connecting cylinder 615 to docking cylinder 601, the upper arc plate 620 and lower arc plate 621 rotate upward and downward respectively to open. When the rollers 616 rotate in the opposite direction and switch the docking cylinder 601 and connecting cylinder 615 to connecting cylinder 615 to connect and transport water, the upper arc plate 620 and lower arc plate 621 rotate upward and downward respectively to close, clamping and reinforcing the connecting cylinder 615 and the outer wall of the pipe.

[0031] The working principle of this utility model is as follows:

[0032] In use, the waste liquid is pressurized by the booster pump 5 and enters the filter tank 1. The multi-layer filter screen and activated carbon adsorption layer inside the filter tank 1 remove suspended solids and large molecular impurities from the wastewater. Then, it is transported to the neutralization reactor 2 through pipelines and booster pumps to adjust the pH value of the waste liquid. The neutralized waste liquid is then entered into the oxidation reaction tower 3 through pipelines and booster pumps. Under the catalytic action of the temperature inside the oxidation reaction tower 3, the organic matter is degraded into small molecules or mineralized. Finally, it enters the membrane separation purification tank 4, where the integrated ultrafiltration membrane and reverse osmosis membrane inside the membrane separation purification tank 4 perform dual filtration of the waste liquid to achieve deep purification and produce water that meets national discharge standards.

[0033] When the interior of the booster pump 5 needs cleaning, the roller 616 can be rotated 180° by the motor 618, causing the docking cylinder 601 and connecting cylinder 615 to flip and switch so that the docking cylinder 601 is located at both ends of the booster pump 5. The motor 609 is then driven, causing its output shaft to rotate the gear 605. The gear 605, through the threaded toothed slot 604, pushes the rotating housing 603 and rotating blade 602 to rotate, causing the rotating blade 602 to gradually enter the port of the booster pump 5. This pries up any deposits at both ends of the booster pump 5, and then water is supplied to the angled nozzle 610. High-pressure water can penetrate into the interior of the attached material more quickly by prying it up, washing away the material and allowing it to flow out through the telescopic pipe 614 with the water flow. After cleaning, the motor 618 can be driven to rotate in the opposite direction again, causing the roller 616 to rotate 180°, so that the docking cylinder 601 and the connecting cylinder 615 are flipped and switched so that the connecting cylinder 615 is located at both ends of the booster pump 5. At the same time, the roller 616 rotates in the opposite direction, causing the upper arc plate 620 and the lower arc plate 621 to rotate upward and downward and close through the belt 622, clamping and reinforcing the connecting cylinder 615 and the outer wall of the pipe.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
