Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an intelligent dosing device and control system for environmental wastewater treatment. Background Technology

[0002] Most industrial wastewater or agricultural sewage contains many complex chemical components. The treatment of this type of sewage requires the addition of chemicals before the next step of filtration and purification. CN215711868U discloses a sewage treatment device for chemical dosing. When the sewage is stirred in the treatment tank, the control box controls the dosing pipe to add the treatment agent intermittently, so as to avoid adding too much treatment agent at one time, which would cause uneven diffusion or failure to dissolve quickly and stick together, thus fully improving the dissolution rate of the treatment agent.

[0003] However, the aforementioned patent has the drawback of a fixed discharge position, which is not conducive to the dispersion of the agent into the sewage, reduces the fusion effect between the agent and the sewage, and makes it impossible to reasonably set the amount of agent added, making it difficult to achieve the effect of automatic quantitative dosing. In addition, the traditional fixed stirring also easily leads to low flow of sewage far from the stirring center, resulting in poor contact with the agent and further reducing the sewage treatment effect.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent dosing device and control system for environmental wastewater treatment, so as to solve the technical defects mentioned in the background art.

[0006] The objective of this invention can be achieved through the following technical solution: an intelligent dosing device for environmental wastewater treatment, comprising a treatment tank, a control panel fixedly connected to the front surface of the treatment tank, guide slides symmetrically fixedly connected to the upper surface of the treatment tank, an adjusting motor fixedly connected to one side of the guide slide, an adjusting shaft internally connected to the side of the adjusting motor near the guide slide, and the adjusting shaft being located inside the guide slide, and a guide slider sleeved on the outside of the adjusting shaft, and the guide slider being slidably connected to the guide slide;

[0007] A servo motor is fixedly connected to the front surface of the guide slider. An adjusting screw is internally connected to the side of the servo motor near the guide slider. A positioning slide is sleeved on the outside of the adjusting screw. A stirring rack is fixedly connected to the lower surface of the positioning slide, and a medicine tank is fixedly connected to the upper surface of the positioning slide.

[0008] Preferably, a limiting plate is fixedly connected to one side of the medicine container, an auxiliary motor is fixedly connected to the lower surface of the limiting plate, a drive shaft is internally connected to the lower surface of the auxiliary motor, an auxiliary turntable is fixedly connected to the lower surface of the drive shaft, a positioning pin is fixedly connected to the lower surface of the auxiliary turntable, a redirecting pull ring is movably sleeved on the outside of the positioning pin, and a protrusion is fixedly sleeved on the outside of the drive shaft.

[0009] Preferably, a discharge pipe is fixedly connected to the side of the medicine tank near the limiting plate, a plastic hose is sleeved at the end of the discharge pipe away from the medicine tank, and the lower end of the plastic hose is located inside the redirecting ring. A discharge shaft is movably inserted into the inside of the discharge pipe, a redirecting plate is fixedly connected to the end of the discharge shaft away from the discharge pipe, and a return spring is fixedly connected to the lower surface of the redirecting plate outside the discharge shaft.

[0010] The present invention also proposes a control system for an intelligent dosing device for environmental wastewater treatment, wherein the control panel is internally equipped with a dosing management platform, an information acquisition unit, a self-testing and verification unit, a matching and analysis unit, and a dosing management unit;

[0011] When the dosing management platform generates an operation and management instruction, it sends the instruction to the information collection unit and the self-inspection and verification unit. Upon receiving the instruction, the information collection unit immediately collects the wastewater information from the treatment tank and sends it to the matching and analysis unit. Upon receiving the wastewater information, the matching and analysis unit immediately performs dosing matching and monitoring analysis on the wastewater information.

[0012] Preferably, the drug dosing matching and monitoring analysis operation process is as follows:

[0013] The wastewater treatment time period was collected and set as a time threshold. The line connecting the midpoints of the two shorter sides of the treatment tank was used as the X-axis, with the direction from left to right. The line connecting the midpoints of the two longer sides of the treatment tank was used as the Y-axis, with the direction from front to back. The intersection point of the X-axis and Y-axis was set as point O. Then, the treatment tank was divided into four regions using the first, second, third, and fourth quadrants of the coordinate system, and these regions were set as treatment areas.

[0014] Wastewater information from each treatment area is acquired, including water level and particle concentration. The product of the water level and particle concentration after data normalization is set as the reagent requirement value. The reagent requirement value is compared and analyzed with the preset reagent requirement value range stored in the system. The reagent requirement value generates a matching dosing value for the corresponding preset reagent requirement value range. The matching dosing value for each treatment area is acquired and sent to the dosing management unit.

[0015] Preferably, upon receiving the matching dosing values ​​for each processing area, the dosing management unit immediately displays the corresponding matching dosing values ​​for each processing area;

[0016] The dosing management unit is also used to obtain the positioning coordinates of the current positioning slide, which represent the coordinates of the intersection of the line connecting the two long sides and the line connecting the two short sides of the positioning slide. At the same time, it obtains the line connecting the two long sides and the line connecting the two short sides of each processing area, sets the intersection of the line connecting the two long sides and the line connecting the two short sides as the area stirring point, and then adjusts the positioning of the stirring rack according to the positioning coordinates of the current positioning slide and the area stirring point of each processing area, and performs stirring treatment in sequence according to the quadrant order.

[0017] Preferably, the self-inspection and verification unit is used to collect and process the dosing information from the operation and management instruction box in response to the operation and management instructions, and to perform dosing supervision and assessment analysis on the dosing information. The specific dosing supervision and assessment analysis process is as follows:

[0018] The dosing information for each processing area within the time threshold is obtained. The dosing information represents the dosing metering value, which represents the total amount of reagent flowing out of the plastic tube. The dosing metering value is then compared and analyzed with the matched dosing value.

[0019] If the dosage value matches the matched dosage value, a standard signal is generated; if the dosage value does not match the matched dosage value, a deviation signal is generated.

[0020] The beneficial effects of this invention are as follows:

[0021] (1) This invention completes automatic and rational sewage dosing treatment through mechanical and system linkage. Through the cooperation between components, sewage in different areas is stirred, which helps to improve the flow rate of sewage and the full contact effect between sewage and agent. The protrusion drives the deflector plate to move intermittently, achieving the effect of intermittent dosing. During the intermittent dosing process, the agent is deflected and discharged, which helps to increase the discharge dispersion area of ​​the agent.

[0022] (2) The present invention also achieves reasonable dosing management and automatic regional stirring and positioning adjustment through data analysis. According to the chemical demand of different treatment areas, the chemical dosing is reasonable and targeted to improve the sewage treatment effect. At the same time, the dosing amount of each treatment area is monitored so as to intuitively understand the dosing situation of each treatment area and adjust the dosing components in a timely manner to ensure the dosing accuracy of the dosing components.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 6 As shown, the present invention is an intelligent dosing device for environmental wastewater treatment, including a treatment tank 1. A control panel 2 is fixedly connected to the front surface of the treatment tank 1. Guide slide plates 3 are symmetrically fixedly connected to the upper surface of the treatment tank 1. An adjustment motor 4 is fixedly connected to one side of the guide slide plate 3. An adjustment shaft 5 is internally connected to the side of the adjustment motor 4 near the guide slide plate 3 and is located inside the guide slide plate 3. A guide slider 6 is sleeved on the outside of the adjustment shaft 5 and is slidably connected to the guide slide plate 3.

[0033] A servo motor 7 is fixedly connected to the front surface of the guide slider 6. An adjusting screw 8 is internally connected to the side of the servo motor 7 near the guide slider 6. A positioning slide plate 9 is sleeved on the outside of the adjusting screw 8. A stirring rack 10 is fixedly connected to the lower surface of the positioning slide plate 9. A medicine tank 11 is fixedly connected to the upper surface of the positioning slide plate 9.

[0034] It should be noted that when using treatment tank 1, wastewater is introduced into the interior of treatment tank 1. The operating control panel 2 controls the operation of regulating motor 4 and servo motor 7. Regulating motor 4 drives guide slider 6 to slide inside guide slide plate 3 via adjusting shaft 5. At the same time, servo motor 7 drives positioning slide plate 9 to move via adjusting screw 8. The operation of regulating motor 4 and servo motor 7 is adjusted to achieve the stirring and positioning of stirring rack 10, so as to stir wastewater in different areas. This helps to improve the flow rate of wastewater and the full contact between wastewater and the agent. After adjusting the position of positioning slide plate 9, the stirring rack 10 is controlled to stir the wastewater.

[0035] Among them, a limiting plate 12 is fixedly connected to one side of the medicine tank 11, an auxiliary motor 13 is fixedly connected to the lower surface of the limiting plate 12, a drive shaft 14 is internally connected to the lower surface of the auxiliary motor 13, an auxiliary turntable 15 is fixedly connected to the lower surface of the drive shaft 14, a positioning pin 16 is fixedly connected to the lower surface of the auxiliary turntable 15, a redirecting pull ring 17 is movably sleeved on the outside of the positioning pin 16, and a protrusion 18 is fixedly sleeved on the outside of the drive shaft 14.

[0036] In this embodiment of the invention, the positioning pin 16 is located near the lower surface of the auxiliary turntable 15 so that the reversing pull ring 17 can drive the plastic hose 20 to change direction, which helps to increase the discharge dispersion area of ​​the agent and thus helps to improve the mixing effect of the agent.

[0037] Among them, a discharge pipe 19 is fixedly connected to the side of the medicine tank 11 near the limiting plate 12. A plastic hose 20 is sleeved on the end of the discharge pipe 19 away from the medicine tank 11, and the lower end of the plastic hose 20 is located inside the redirecting pull ring 17. A discharge shaft 21 is movably inserted into the inside of the discharge pipe 19. A redirecting plate 22 is fixedly connected to the end of the discharge shaft 21 away from the discharge pipe 19. A return spring 23 is fixedly connected to the lower surface of the redirecting plate 22 outside the discharge shaft 21.

[0038] It should be noted that during the contact between the protrusion 18 and the redirecting plate 22, the return spring 23 first undergoes elastic deformation, and the discharge shaft 21 rotates simultaneously. This causes the medicine inside the medicine tank 11 to flow out from the discharge pipe 19 and be redirected and dispersed by the plastic hose 20, falling into the upper part of the processing area. That is, during the rotation of the drive shaft 14, the drive shaft 14 drives the positioning pin 16 below the auxiliary turntable 15 to rotate. As the positioning pin 16 rotates, it pulls the plastic hose 20 through the redirecting pull ring 17 to move, thereby changing the discharge direction during the addition of medicine, which helps to increase the discharge dispersion area of ​​the medicine.

[0039] In this embodiment of the invention, a baffle plate is fixedly connected to one end of the discharge shaft 21 located inside the discharge pipe 19. When the discharge shaft 21 is not in contact with the protrusion 18, the baffle plate blocks and seals the discharge pipe 19, thereby preventing the medicine from flowing out.

[0040] In this embodiment of the invention, when using the treatment tank 1, wastewater is introduced into the interior of the treatment tank 1. The operating control panel 2 controls the operation of the regulating motor 4 and the servo motor 7. The regulating motor 4 drives the guide slider 6 to slide inside the guide slide plate 3 via the adjusting shaft 5. At the same time, the servo motor 7 drives the positioning slide plate 9 to move via the adjusting screw 8. By adjusting the operation of the regulating motor 4 and the servo motor 7, the stirring position of the stirring rack 10 is achieved, so as to stir the wastewater in different areas, which helps to improve the flow rate of wastewater and the full contact between wastewater and the agent.

[0041] After adjusting the position of the positioning slide plate 9, the mixing frame 10 is controlled to mix the sewage. During the mixing process, the auxiliary motor 13 is controlled to work. The auxiliary motor 13 drives the protrusion 18 to rotate synchronously through the transmission shaft 14, so that the protrusion 18 drives the redirecting plate 22 to move intermittently during the rotation. During the contact between the protrusion 18 and the redirecting plate 22.

[0042] First, the return spring 23 undergoes elastic deformation, and at the same time, the discharge shaft 21 rotates, causing the medicine inside the medicine tank 11 to flow out from the discharge pipe 19 and fall into the upper part of the treatment area through the deflection and dispersion of the plastic hose 20. That is, during the rotation of the drive shaft 14, the drive shaft 14 drives the positioning pin 16 below the auxiliary turntable 15 to rotate. As the positioning pin 16 rotates, the positioning pin 16 pulls the plastic hose 20 through the deflection pull ring 17 to move. Changing the discharge direction during the addition of medicine helps to increase the discharge dispersion area of ​​the medicine.

[0043] When the protrusion 18 separates from the redirecting plate 22, the discharge shaft 21 returns to its initial position due to the restoring force of the return spring 23, thereby sealing the discharge pipe 19. During the intermittent discharge process, the dosage value is judged to ensure the accuracy of dosing in each treatment area, thereby ensuring the accuracy of dosing in the treatment box 1.

[0044] In this embodiment of the invention, the initial position refers to the position when the redirecting plate 22 and the protrusion 18 are not in contact, that is, the position of the redirecting plate 22 when the discharge pipe 19 is not discharging.

[0045] In this embodiment of the invention, traditional sewage mixing adopts fixed-position mixing, which results in low sewage flow in areas far from the mixing center, poor contact with the agent, and thus affects the sewage treatment effect. Furthermore, it is impossible to add a reasonable dosage of agent based on the sewage information of each area.

[0046] Example 2: In this embodiment of the invention, the present invention also proposes a control system for an intelligent dosing device for environmental wastewater treatment, wherein a dosing management platform, an information acquisition unit, a self-testing and verification unit, a matching and analysis unit, and a dosing management unit are provided inside the control panel 2;

[0047] When the dosing management platform generates an operation and management instruction, it sends the instruction to the information acquisition unit and the self-inspection and verification unit. Upon receiving the instruction, the information acquisition unit immediately collects the wastewater information from treatment tank 1 and sends it to the matching and analysis unit. Upon receiving the wastewater information, the matching and analysis unit immediately performs dosing matching and monitoring analysis to ensure appropriate dosing based on feedback, thereby improving wastewater treatment efficiency and dosing rationality. The specific dosing matching and monitoring analysis process is as follows:

[0048] The wastewater treatment period was collected and set as a time threshold. The line connecting the midpoints of the two short sides of treatment tank 1 was used as the X-axis, with the direction from left to right. The line connecting the midpoints of the two long sides of treatment tank 1 was used as the Y-axis, with the direction from front to back. The intersection point of the X-axis and Y-axis was set as point O. Then, treatment tank 1 was divided into four regions using the first, second, third, and fourth quadrants of the coordinate system, and these regions were set as treatment areas.

[0049] Wastewater information from each treatment area is acquired, including water level and particle concentration. The product of the water level and particle concentration values ​​after data normalization is set as the required reagent value. This required reagent value is then compared with a pre-defined range of reagent requirements stored internally. A matching dosing value is generated for each pre-defined range. For example, if the required reagent value corresponds to the first range, the matching dosing value is 2 liters; if it corresponds to the second range, the matching dosing value is 3 liters; if it corresponds to the third range, the matching dosing value is 4 liters, and so on. The specific dosing value is set by personnel based on requirements.

[0050] In this embodiment of the invention, the processing box 1 is a cuboid;

[0051] The matching dosing values ​​for each treatment area are obtained and sent to the dosing management unit. Upon receiving the matching dosing values ​​for each treatment area, the dosing management unit immediately displays the corresponding matching dosing values ​​on each treatment area. This allows for reasonable and targeted dosing based on the chemical requirements of different treatment areas during wastewater treatment, thereby improving the wastewater treatment effect.

[0052] The dosing management unit is also used to obtain the positioning coordinates of the current positioning slide plate 9. The positioning coordinates represent the coordinates of the intersection of the line connecting the two long sides and the line connecting the two short sides of the positioning slide plate 9. At the same time, it obtains the line connecting the two long sides and the line connecting the two short sides of each treatment area. The intersection of the line connecting the two long sides and the line connecting the two short sides is set as the area mixing point. Based on the positioning coordinates of the current positioning slide plate 9 and the area mixing points of each treatment area, the mixing frame 10 is positioned and adjusted, and the mixing is performed sequentially according to the quadrant order. This helps to improve the wastewater treatment efficiency and realize automatic area mixing and positioning adjustment, while also helping to improve the full contact between wastewater and chemicals.

[0053] Upon receiving the operation and management instruction, the self-inspection and verification unit immediately collects the dosing information of treatment tank 1 and performs dosing supervision and evaluation analysis on the dosing information to determine whether the dosing of treatment tank 1 is accurate, so as to provide timely feedback and management to ensure the dosing accuracy of treatment tank 1. The specific dosing supervision and evaluation analysis process is as follows:

[0054] The dosing information for each processing area within the time threshold is obtained. The dosing information represents the dosing metering value, which represents the total amount of reagent flowing out of the plastic tube 20. The dosing metering value is then compared and analyzed with the matched dosing value.

[0055] If the dosage value is equal to the matched dosage value, a standard signal is generated; if the dosage value is not equal to the matched dosage value, a deviation signal is generated.

[0056] The standard signal and deviation signal are sent to the dosing management unit. Upon receiving the standard signal and deviation signal, the dosing management unit immediately displays the preset warning text corresponding to the standard signal and deviation signal on the corresponding processing area, so as to intuitively understand the dosing status of each processing area and make timely adjustments to the dosing components to ensure the dosing accuracy of the dosing components.

[0057] In summary, this invention achieves automatic and rational wastewater dosing treatment through mechanical and system linkage. By coordinating the components, wastewater in different areas is stirred, which helps to improve the flow rate of wastewater and the full contact between wastewater and the agent. Furthermore, the protrusion 18 drives the redirecting plate 22 to move intermittently, thereby achieving the effect of intermittent dosing. During the intermittent dosing process, the agent is redirected and discharged, which helps to increase the dispersion area of ​​the agent.

[0058] By using data analysis, reasonable dosing management and automatic zone mixing and positioning adjustments can be achieved. Based on the chemical requirements of different treatment zones, reasonable and targeted dosing can be performed to improve the wastewater treatment effect. At the same time, the dosing amount in each treatment zone can be monitored to intuitively understand the dosing situation in each treatment zone and make timely adjustments to the dosing components to ensure the accuracy of dosing.

[0059] The threshold value is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by those skilled in the art for each group of sample data. As long as it does not affect the ratio between the parameter and the quantized value, it is acceptable. The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
