Technical Field

[0001] This application relates to the field of wastewater treatment technology, specifically to a wastewater treatment device. Background Technology

[0002] Photovoltaic wastewater treatment refers to the specialized process of purifying and treating wastewater generated during the production process of the photovoltaic industry. This wastewater mainly comes from silicon wafer cutting, cell manufacturing, and module cleaning, and contains acidic and alkaline substances, fluorides, heavy metals, and other organic pollutants. Its core purpose is to remove harmful impurities through physical, chemical, or biological methods so that the wastewater meets discharge standards or reuse requirements.

[0003] Existing wastewater treatment devices suffer from low mixing efficiency between chemicals and wastewater, resulting in chemicals failing to diffuse quickly and evenly in the wastewater. This can easily lead to excessive or insufficient chemicals in certain areas, reducing wastewater treatment efficiency and hindering their use. Utility Model Content

The delivery pump is configured to drive the wastewater in the wastewater treatment chamber to flow into the reagent containing chamber and premix it with the reagent before inputting it into the wastewater treatment chamber.

[0009] In some embodiments, the premixed liquid outlet tube is a flexible tube;

[0010] The premixing assembly also includes a spray pipe and a nozzle. The spray pipe is rotatably mounted on the wall of the wastewater treatment chamber, and the nozzle is mounted on the spray pipe and communicates with the premixed liquid outlet pipe through the spray pipe.

[0011] The wastewater treatment device also includes an adjustment component, which is used to drive the spray pipe to swing around its rotation axis to adjust the spray direction of the nozzle.

The remaining portion of the linkage and the friction element are located inside the wastewater treatment chamber, and the friction element is mounted on the linkage and frictionally connected to the side of the spray pipe opposite to the nozzle. Under the action of the adjustment drive, when the linkage drives the friction element to reciprocate up and down in a direction perpendicular to the rotation axis of the spray pipe, the spray pipe drives the nozzle to swing by means of the friction between itself and the friction element.

[0013] In some embodiments, the adjustment assembly further includes a mounting shell, a cam, a top plate, and an elastic element, all disposed outside the wastewater treatment chamber. The mounting shell has a mounting cavity, and the cam, the top plate, and the elastic element are all installed inside the mounting cavity. The cam is connected to the adjustment drive component, the top plate abuts against the cam, and the linkage component and the elastic element are all installed on the top side of the top plate facing away from the cam. The elastic element abuts between the top plate and the mounting shell.

[0014] The adjusting drive is used to drive the cam to lift the linkage, and the elastic element is used to provide an elastic force to drive the top plate to lower the linkage.

[0015] In some embodiments, the elastic element is a compression spring, and the elastic element is sleeved on the linkage element.

[0016] In some embodiments, the adjustment assembly further includes a guide rod and a sliding sleeve, both of which are located within the wastewater treatment chamber. The sliding sleeve is fitted onto the guide rod and connected to the friction element.

[0017] In some embodiments, the premixed liquid outlet pipe includes a main section and multiple branch sections, wherein the main section is connected between the drug receiving cavity and the branch sections;

[0018] The spray pipes are multiple and are spaced apart along the lifting direction of the linkage. Each spray pipe corresponds to and is connected to a branch section. Each spray pipe is equipped with multiple nozzles arranged along its extension direction.

[0019] In some embodiments, the premixing assembly further includes a metering pump connected to the reagent container and used to input a dosage of reagent into the reagent container that matches the amount of wastewater in the wastewater treatment chamber.

One end of the stirring shaft is connected to the stirring drive component, and the other end of the stirring shaft away from the stirring drive component is rotatably connected to the wastewater treatment container through the bearing. The second stirring blade is disposed away from the stirring drive component relative to the first stirring blade, and the second stirring blade is used to push wastewater in the direction toward the first stirring blade.

[0022] In some embodiments, the wastewater treatment device further includes a wastewater inlet pipe and a wastewater outlet pipe, both of which are connected to the wastewater treatment chamber.

[0023] Compared with the prior art, this application has the following beneficial effects:

[0024] The aforementioned wastewater treatment device, through the design of a premixing component, draws a portion of the wastewater from inside the wastewater treatment chamber into the reagent containing chamber, completing the premixing of the reagent and wastewater before introducing it into the wastewater treatment chamber. This allows the reagent to diffuse evenly within the wastewater treatment chamber, thus avoiding the problem of excessively high or low local concentrations that can easily occur when the reagent is directly injected into the wastewater treatment chamber. This lays the foundation for subsequent uniform mixing. Combined with the use of a stirring component, the reagent and wastewater can be fully mixed, thereby improving the wastewater purification efficiency. Attached Figure Description

[0043] Photovoltaic wastewater treatment refers to the specialized process of purifying and treating wastewater generated during the production process of the photovoltaic industry. This wastewater mainly comes from silicon wafer cutting, cell manufacturing, and module cleaning, and contains acidic and alkaline substances, fluorides, heavy metals, and other organic pollutants. Its core purpose is to remove harmful impurities through physical, chemical, or biological methods so that the wastewater meets discharge standards or reuse requirements.

[0044] Existing wastewater treatment devices suffer from low mixing efficiency between chemicals and wastewater, resulting in chemicals failing to diffuse quickly and evenly in the wastewater. This can easily lead to excessive or insufficient chemicals in certain areas, reducing wastewater treatment efficiency and hindering their use.

[0045] Please see Figures 1 to 3 In order to alleviate the above problems, the applicant has conducted in-depth research and designed a wastewater treatment device 100, which includes a wastewater treatment container 10, a stirring component 20 and a premixing component 30. The wastewater treatment container 10 has a wastewater treatment chamber 11. The stirring assembly 20 includes a stirring drive 21 and a stirring element 22. The stirring drive 21 is installed outside the wastewater treatment chamber 11, and the stirring element 22 is connected to the stirring drive 21. The stirring element 22 extends at least partially into the wastewater treatment chamber 11. The premixing assembly 30 includes a dosing container 31, a premixing inlet pipe 32, a premixing outlet pipe 33, and a delivery pump 34, all installed outside the treatment chamber. The dosing container 31 has a reagent containing chamber. The premixing inlet pipe 32 and the premixing outlet pipe 33 are both connected to the wastewater treatment chamber 11. The delivery pump 34 is connected between the premixing inlet pipe 32 and the reagent containing chamber. The delivery pump 34 is configured to drive the wastewater in the wastewater treatment chamber 11 to flow into the reagent containing chamber and premix it with the reagent before inputting it into the wastewater treatment chamber 11.

[0046] Specifically, the wastewater treatment container 10 includes a first shell 12 and a second shell 13 that are interconnected. The first shell 12 is an arc-shaped shell and is used to install the stirring assembly 20. The second shell 13 is a rectangular shell and is used to install the premixing assembly 30.

[0047] The stirring drive 21 is installed on the top side of the first housing 12, and the stirring component 22 is installed inside the first housing 12 and extends approximately along the height direction of the first housing 12.

[0048] The premixing assembly 30 is mounted on the second housing 13 and includes a dosing container 31, a premixing inlet pipe 32, a premixing outlet pipe 33, and a delivery pump 34. The dosing container 31 is used to store reagents that can chemically react with wastewater. The wastewater treatment chamber 11, the premixing inlet pipe 32, the delivery pump 34, the dosing container 31, and the premixing outlet pipe 33 are sequentially and cyclically connected to form a path for wastewater flow.

[0049] In actual operation, the transfer pump 34 drives the wastewater in the wastewater treatment chamber 11 to flow into the reagent container chamber, where it is premixed with the reagent and then returns to the wastewater treatment chamber 11 through the premixed liquid outlet pipe 33. Afterwards, the stirring drive 21 drives the stirring component 22 to stir the wastewater and reagent in the wastewater treatment chamber 11, ensuring that the reagent and wastewater are fully mixed and react, thereby achieving wastewater purification.

[0050] In this application, a premixing component 30 is designed to extract a portion of the wastewater from the wastewater treatment chamber 11 into the reagent containing chamber, completing the premixing of the reagent and wastewater before introducing it into the wastewater treatment chamber 11. This allows the reagent to diffuse evenly within the wastewater treatment chamber 11, thus avoiding the problem of excessively high or low local concentrations that easily occur when the reagent is directly injected into the wastewater treatment chamber 11. This lays the foundation for subsequent uniform mixing. Combined with the use of the stirring component 20, the reagent and wastewater can be fully mixed to improve the wastewater purification efficiency.

[0051] Please see Figure 3 In some embodiments, the stirring assembly 20 further includes a bearing 23 located in the wastewater treatment chamber 11; the stirring component 22 includes a stirring shaft 221 and a first stirring blade 222 and a second stirring blade 223 arranged sequentially at axial intervals along the stirring shaft 221. One end of the stirring shaft 221 is connected to the stirring drive component 21, and the other end of the stirring shaft 221 away from the stirring drive component 21 is rotatably connected to the wastewater treatment container 10 through the bearing 23. The second stirring blade 223 is arranged away from the stirring drive component 21 relative to the first stirring blade 222, and the second stirring blade 223 is used to push wastewater in the direction toward the first stirring blade 222.

[0052] The bearing 23 is located at the bottom of the wastewater treatment chamber 11. The top end of the stirring shaft 221 is connected to the stirring drive component 21, and the bottom end of the stirring shaft 221 is movably connected to the bearing 23. The first stirring blade 222 and the second stirring blade 223 are arranged at intervals along the axial direction of the stirring shaft 221, with the second stirring blade 223 being farther away from the stirring drive component 21 relative to the first stirring blade 222. The stirring drive component 21 can drive the stirring shaft 221 to rotate the first stirring blade 222 and the second stirring blade 223 to stir the wastewater and the reagent, thereby achieving thorough mixing of the wastewater and the reagent.

[0053] The first stirring blade 222 and the second stirring blade 223 can be one or more, and the specific configuration can be determined according to requirements.

[0054] Specifically, the first stirring blade 222 is located in the middle of the wastewater treatment chamber 11 in the height direction and is mainly used to stir the wastewater in the middle of the wastewater treatment chamber 11. The second stirring blade 223 is located at the bottom of the wastewater treatment chamber 11. The second stirring blade 223 can be a guide vane group or a propeller-type stirring blade group, etc. The second stirring blade 223 can not only stir the wastewater at the bottom of the wastewater treatment chamber 11, but also push the wastewater towards the first stirring blade 222 during the stirring process, thereby forming a circulating flow of wastewater. This design can break the limitations of traditional single stirring, which can only act locally and has low mixing efficiency, and ensure that the reagent and wastewater are quickly and fully mixed, thereby improving the reaction rate. The bearing 23 can increase the stability of the stirring shaft 221 during rotation.

[0055] In some embodiments, the agitator 22 can also remove the second agitator blade 223, and a circulating water pump is provided at the bottom of the wastewater treatment container 10. The circulating water pump pumps the wastewater at the bottom of the wastewater treatment container 10 to the top of the wastewater treatment container 10, and achieves uniform spraying by setting an annular water spray pipe along the circumference of the wastewater treatment container 10. By combining the agitation action of the circulating water pump with the first agitator blade 222, an upper and lower circulation mixing is formed, which can also achieve full mixing of the agent and wastewater, thereby improving the efficiency of wastewater purification.

[0056] Please see Figure 1 , Figures 3 to 5 In some embodiments, the premixed outlet pipe 33 is a flexible hose; the premixing assembly 30 also includes a spray pipe 35 and a nozzle 36. The spray pipe 35 is rotatably mounted on the wall of the wastewater treatment chamber 11, and the nozzle 36 is mounted on the spray pipe 35 and communicates with the premixed outlet pipe 33 through the spray pipe 35; the wastewater treatment device 100 also includes an adjustment assembly 40, which is used to drive the spray pipe 35 to swing around its rotation axis to adjust the spraying direction of the nozzle 36.

[0057] Specifically, the spray pipe 35 is horizontally arranged along the width direction of the second housing 13, and the spray pipe 35 oscillates about a rotation axis extending in this direction under the action of the adjusting component 40. Optionally, one or more spray heads 36 are provided on the spray pipe 35.

[0058] In actual operation, after the reagent and wastewater are mixed in the reagent container, they are transported to the nozzle 36 through the premixed liquid outlet pipe 33 and the spray pipe 35. At this time, the spray direction of the nozzle 36 can be adjusted by driving the spray pipe 35 to swing continuously through the adjustment component 40, so as to realize the dispersion of the reagent inside the wastewater treatment chamber 11, improve the uniformity of the contact between the reagent and the wastewater, avoid local over- or under-dosage of reagent, thereby improving the purification efficiency and reducing reagent waste.

[0059] Understandably, in order to ensure that the premixed liquid outlet pipe 33 can swing with the spray pipe 35, the premixed liquid outlet pipe 33 should be designed as a flexible hose.

[0060] Please see Figure 4 and Figure 5In some embodiments, the adjustment assembly 40 includes an adjustment drive 41, a linkage 46, and a friction element 47. Part of the linkage 46 and the adjustment drive 41 are located outside the wastewater treatment chamber 11, and the linkage 46 is connected to the adjustment drive 41 in a transmission manner. The remaining part of the linkage 46 and the friction element 47 are located inside the wastewater treatment chamber 11, and the friction element 47 is mounted on the linkage 46 and is frictionally connected to the side of the spray pipe 35 facing away from the nozzle 36. Under the action of the adjustment drive 41, when the linkage 46 drives the friction element 47 to reciprocate up and down in a direction perpendicular to the rotation axis of the spray pipe 35, the spray pipe 35 drives the nozzle 36 to swing by means of the friction between it and the friction element 47.

[0061] Specifically, the linkage 46 includes a first section 461, an intermediate section 462 and a second section 463. The intermediate section 462 is connected between the first section 461 and the second section 463. The first section 461 and the intermediate section 462 are both located outside the wastewater treatment chamber 11. The first section 461 is connected to the adjustment drive 41 for transmission. The second section 463 extends at least partially into the wastewater treatment chamber 11 and can be fitted with a friction element 47.

[0062] As an example, the adjustment drive 41 can be a servo motor, motor, etc., and can be set according to requirements.

[0063] In actual operation, the driving component 41 drives the linkage component 46 to move the friction component 47 back and forth. During the movement of the friction component 47, the friction between the friction component 47 and the spray pipe 35 causes the spray pipe 35 and the nozzle 36 to swing, thereby adjusting the spraying direction of the nozzle 36. This allows the mixed solution formed by the agent and wastewater to be sprayed evenly into the wastewater treatment chamber 11, thereby achieving rapid and uniform dispersion of the agent and increasing the mixing efficiency of the agent and wastewater.

[0064] Please see Figure 4 and Figure 5 Furthermore, in some embodiments, the adjusting assembly 40 further includes a mounting shell 42, a cam 43, a top plate 44, and an elastic element 45, all disposed outside the wastewater treatment chamber 11. The mounting shell 42 has a mounting cavity 421, in which the cam 43, top plate 44, and elastic element 45 are all installed. The cam 43 is connected to the adjusting drive 41, the top plate 44 abuts against the cam 43, and the linkage 46 and elastic element 45 are both installed on the top side of the top plate 44 facing away from the cam 43. The elastic element 45 abuts between the top plate 44 and the mounting shell 42. The adjusting drive 41 is used to drive the cam 43 to lift the linkage 46, and the elastic element 45 is used to provide an elastic force that drives the top plate 44 to lower the linkage 46.

[0065] As an example, the adjusting drive 41 is located outside the mounting cavity 421, and the output shaft of the adjusting drive 41 passes through the mounting housing 42 and is connected to the cam 43 inside the mounting housing 42. A top plate 44 is provided on the top of the cam 43, and the first section 461 of the linkage 46 is fixedly connected to the top of the top plate 44. The elastic member 45 is located on the top of the top plate 44 and is connected to the inner wall of the mounting cavity 421 and the top plate 44.

[0066] In actual operation, the adjusting drive component 41 drives the cam 43 to rotate, and the cam 43 lifts the top plate 44, enabling the top plate 44 to drive the linkage component 46 and friction component 47 to rise. During the rising process of the top plate 44, the elastic component 45 is further compressed. As the cam 43 continues to rotate, the top plate 44, under the action of the elastic component 45, drives the linkage component 46 and friction component 47 to descend. During this process, controlled by the elastic component 45, the top plate 44 always abuts against the cam 43.

[0067] By relying on the coordinated operation of the adjusting drive component 41, mounting shell 42, cam 43, top plate 44, elastic component 45, linkage component 46 and friction component 47, the spray nozzle 36 is continuously oscillating, so that the premixed agent and wastewater can be sprayed in a dispersed manner in the wastewater treatment chamber 11 through the spray nozzle 36, which greatly increases the contact area between the agent and wastewater in the wastewater treatment chamber 11 and solves the problems of limited spray range and uneven mixing of traditional fixed spray nozzles 36.

[0068] Furthermore, in some embodiments, the elastic element 45 is a compression spring, and the elastic element 45 is sleeved on the linkage element 46. Specifically, the elastic element 45 is sleeved on the first segment 461 of the linkage element 46. In this design, the linkage element 46 guides the elastic element 45 to compress, making the compression deformation of the elastic element 45 stable, thereby smoothly pushing the top plate 44 down.

[0069] In some embodiments, the inner wall of the mounting cavity 421 is further provided with a slide rail 422, and a slide groove 441 is provided on the top plate 44. The slide rail 422 passes through the slide groove 441 and can guide the top plate 44 to rise and fall, so as to improve the stability of the rise and fall of the top plate 44.

[0070] Please see Figure 4 In some embodiments, the adjustment assembly 40 further includes a guide rod 48 and a sliding sleeve 49, both located within the wastewater treatment chamber 11. The sliding sleeve 49 is fitted onto the guide rod 48 and connected to the friction element 47. By setting the guide rod 48 and the sliding sleeve 49 to guide the friction element 47 to slide up and down within the wastewater treatment chamber 11, the stability of the sliding of the friction element 47 can be improved, enabling the friction element 47 to smoothly drive the spray pipe 35 to swing.

[0071] In this application, the slide rail 422 and the slide groove 441 cooperate to achieve the smoothness of the lifting and lowering of the top plate 44, and the slide sleeve 49 and the guide rod 48 cooperate to achieve the smoothness of the lifting and lowering of the friction plate. This design ensures that the power of the adjusting drive component 41 can be stably transmitted to the nozzle 36, ensuring that the nozzle 36 swings evenly and moves stably, which is the core mechanical guarantee for achieving uniform dispersion of the agent.

[0072] Of course, in this application, the specific structure of the adjustment component 40 is not limited to the one described above. In some other embodiments, the adjustment component 40 can also be replaced by a stepper motor and a crank-connecting rod mechanism. The stepper motor directly drives the crank-connecting rod mechanism to drive the nozzle 36 to oscillate back and forth, without the need to transmit power through the friction element 47, and can still achieve the effect of the nozzle 36 oscillating and dispersing the liquid.

[0073] Please see Figures 1 to 4 Furthermore, in some embodiments, the premixed liquid outlet pipe 33 includes a main section 331 and multiple branch sections 332, with the main section 331 connected between the drug container and the branch sections 332; the spray pipe 35 is multiple and spaced along the lifting direction of the linkage 46, with each spray pipe 35 corresponding to and connected to the branch sections 332, and the spray pipe 35 is provided with multiple nozzles 36 arranged along its extension direction.

[0074] The lifting direction of the linkage 46 is the same as the height direction of the second housing 13.

[0075] By designing multiple spray pipes 35, and each spray pipe 35 is equipped with multiple nozzles 36, the mixed solution formed by mixing the agent and wastewater can be sprayed more evenly into the wastewater treatment chamber 11, thereby making the agent and wastewater mix more thoroughly and effectively achieving the purpose of purifying wastewater.

[0076] In some embodiments, the premixing component 30 further includes a metering pump 37, which is in communication with the reagent container and is used to input a dosage of reagent into the reagent container that matches the amount of wastewater in the wastewater treatment chamber 11.

[0077] Specifically, when the reagent and wastewater are mixed in a set ratio, the reagent reacts fully with the wastewater, thereby achieving the purpose of purifying the wastewater. Based on the amount of wastewater injected into the wastewater treatment chamber 11, a metering pump 37 injects a reagent in a set ratio to the wastewater volume into the reagent container chamber. This reduces reagent waste, achieves precise reagent control, and ensures optimal wastewater purification.

[0078] In some embodiments, the premixing component 30 further includes a drug delivery pipe, through which the metering pump 37 delivers a drug in a predetermined proportion to the wastewater volume into the drug receiving chamber, based on the wastewater volume in the wastewater treatment chamber 11.

[0079] Please see Figure 3 In some embodiments, the wastewater treatment device 100 further includes a wastewater inlet pipe 50 and a wastewater outlet pipe 60, both of which are connected to the wastewater treatment chamber 11. The wastewater inlet pipe 50 is used to inject wastewater into the wastewater treatment chamber 11, and the wastewater outlet pipe 60 is used to discharge the purified wastewater to the outside.

[0080] Specifically, the wastewater inlet pipe 50 is located at the top of the second housing 13, and the wastewater outlet pipe 60 is located at the bottom of the second housing 13.

[0081] In some embodiments, the wastewater treatment device 100 further includes an inlet valve and a outlet valve. The inlet valve is installed on the wastewater inlet pipe 50 and is used to control the opening and closing of the wastewater inlet pipe 50. The outlet valve is installed on the wastewater outlet pipe 60 and is used to control the opening and closing of the wastewater outlet pipe 60.

[0082] In some embodiments, the wastewater treatment container 10 is also provided with a viewing window to facilitate staff to observe the wastewater injection and treatment status in the wastewater treatment chamber 11. The bottom of the wastewater treatment container 10 is also provided with an anti-slip plate to facilitate the stable installation of the wastewater treatment container 10 on the bottom, table, or other surfaces of the workshop environment.

[0083] The aforementioned wastewater treatment device 100, through the design of the premixing component 30, draws a portion of the wastewater from inside the wastewater treatment chamber 11 into the reagent containing chamber, completing the premixing of the reagent and wastewater before introducing it into the wastewater treatment chamber 11. This allows the reagent to diffuse evenly within the wastewater treatment chamber 11, thus avoiding the problem of excessively high or low local concentrations that easily occur when the reagent is directly injected into the wastewater treatment chamber 11. This lays the foundation for subsequent uniform mixing. In conjunction with the use of the stirring component 20, the reagent and wastewater can be fully mixed, thereby improving the wastewater purification efficiency.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
