Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a waste liquid treatment device for pesticide production. Background Technology

[0002] Pesticides are chemical agents used in agriculture to control pests and diseases and regulate plant growth. They are widely used in agricultural, forestry and animal husbandry production, environmental and household sanitation pest control and disease prevention, and industrial products for mold and insect prevention. During the production and processing of pesticides, a large amount of wastewater is generated. In order to avoid environmental pollution, pesticide wastewater needs to be treated. When treating pesticide wastewater, coagulation and sedimentation technology is used to remove suspended solids and other colloidal impurities from the wastewater, which is an important step in pesticide wastewater treatment.

[0003] In the coagulation treatment of pesticide wastewater, the wastewater is usually transported to a mixing tank, and coagulants are added. Mechanical stirring is used to achieve thorough mixing of the agent and wastewater, completing the coagulation reaction. However, the amount and quality of pesticide wastewater generated from different batches of pesticide production will vary. The dosage of coagulants cannot be adaptively adjusted according to the amount and quality of wastewater generated from different types of pesticide production, which may result in incomplete treatment of pesticide wastewater and affect the coagulation treatment effect. Therefore, we propose a wastewater treatment device for pesticide production. Summary of the Invention

[0020] This invention has at least the following beneficial effects:

[0021] This invention utilizes a dosing component to add coagulant to a tank. A control component allows for adaptive adjustment of the dosing amount based on wastewater volume and turbidity. Furthermore, the dosing amount can be further adjusted according to the type of pesticide wastewater being treated, such as wastewater from the production of organophosphorus pesticides, herbicides, and insecticides. These three types of pesticide wastewater exhibit different colloidal stability: organophosphorus pesticides have the highest colloidal stability, followed by herbicides, and then insecticides. Therefore, treating organophosphorus pesticide wastewater requires a relatively larger amount of pesticide to improve coagulation efficiency. The first control component adaptively adjusts the stirring speed based on the wastewater volume and turbidity to enhance the mixing effect between the pesticide wastewater and the pesticide, preventing excessively slow stirring from negatively impacting the mixing process. Excessive mixing speed generates excessive shear force, causing the already formed flocs to break down and preventing the formation of large, dense flocs, thus affecting the coagulation effect and wasting energy. The second regulating component automatically adjusts the dosing speed of the dosing component based on the flow rate of the pesticide wastewater as it is transported into the tank, ensuring timely treatment of the wastewater and improving its treatment efficiency. The control component monitors the coagulated wastewater after discharge. If the detected current value exceeds a set threshold, it indicates poor coagulation, and the wastewater is re-entered into the tank for treatment. The dosing amount of the dosing component is then automatically adjusted based on the detected current value to further improve the coagulation effect. If the detected current value meets the requirements, the wastewater is then passed to the next processing stage. Attached Figure Description

[0033] 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.

[0034] Example 1

[0035] Please see Figures 1 to 10 The present invention provides a technical solution: a waste liquid treatment device for pesticide production, comprising: a tank 11, a motor 12 fixedly mounted on the upper side of the tank 11, and a stirring element 13 fixedly mounted on the output end of the motor 12;

[0036] It also includes: a dosing assembly 2, which is located on one side of the tank 11 and is used to add coagulant into the tank 11;

[0037] The first adjustment component 3 is located on one side of the tank 11. The first adjustment component 3 adaptively adjusts the stirring speed according to the amount and turbidity of the pesticide wastewater.

[0038] The second adjustment component 4 is located on one side of the tank 11. The second adjustment component 4 automatically adjusts the dosing speed of the dosing component 2 according to the flow rate of the pesticide wastewater when it is transported into the tank 11.

[0039] The control component 5 is located on one side of the tank 11. The control component 5 adaptively adjusts the dosage of the dosing component 2 according to the wastewater volume and turbidity, and further adjusts the dosage according to different types of pesticide wastewater.

[0040] Control component 6 is located on one side of tank 11. Control component 6 is used to detect the pesticide wastewater discharged from tank 11 after coagulation, and further automatically adjust the dosage of dosing component 2 when the standard is exceeded.

[0041] In the coagulation treatment of pesticide wastewater, the wastewater is transported into tank 11 through the inlet pipe. The motor 12 drives the rotation of the agitator 13, thoroughly mixing the wastewater and pesticide in tank 11 for coagulation. Coagulant is added to tank 11 via the dosing assembly 2, and the dosage of the dosing assembly 2 can be adaptively adjusted according to the wastewater volume and turbidity via the control assembly 5. Furthermore, the dosage can be further adjusted based on the type of pesticide wastewater being treated. The dosage of pesticides used in the production of organophosphorus pesticides, herbicides, and insecticides varies. The colloidal stability of these three types of pesticide wastewater differs: organophosphorus pesticides exhibit the highest colloidal stability, followed by herbicides, and then insecticides. Therefore, treating organophosphorus pesticide wastewater requires a relatively larger dosage to improve coagulation efficiency. The first regulating component 3 can adaptively adjust the stirring speed based on the wastewater volume and turbidity to enhance the coagulation effect. The system improves the mixing effect of pesticide wastewater and pesticides, preventing slow stirring speed from affecting the mixing effect and excessive stirring speed from generating excessive shear force, which can cause the already formed flocs to break down and fail to form large and dense flocs, thus affecting the coagulation effect and causing energy waste. Through the second regulating component 4, the dosing speed of the dosing component 2 can be automatically adjusted according to the flow rate of pesticide wastewater when it is transported into the tank 11, so as to treat the wastewater entering the tank 11 in a timely manner and improve the treatment effect of wastewater. Through the control component 6, the coagulated wastewater can be detected when it is discharged. When the detected flow current value exceeds the set threshold, it indicates that the coagulation effect is poor, and the wastewater will be passed into the tank 11 again for treatment. Based on the detected flow current value, the dosing amount of the dosing component 2 will be automatically adjusted to further improve the coagulation treatment effect of the wastewater. If the detected flow current value meets the requirements, the wastewater will be passed to the next process for treatment.

[0042] The dosing assembly 2 includes a storage cylinder 21 disposed on one side of the tank 11, which stores coagulant. A first connecting pipe 22, which is fixedly connected to the tank 11, is fixedly connected to one side of the storage cylinder 21. A first delivery pump 23 is fixedly mounted on the first connecting pipe 22 and is fixedly mounted on one side of the tank 11. A first solenoid valve is installed on the side of the first connecting pipe 22 near the storage cylinder 21. A mounting base 24 is disposed on the lower side of the storage cylinder 21. Multiple limiting members 25 are fixedly mounted on the upper side of the mounting base 24. The lower side of the storage cylinder 21 is disposed inside the limiting members 25, which can limit the installation of the storage cylinder 21. A pressure sensor 26 is disposed on the upper side of the mounting base 24 and is located on the lower side of the storage cylinder 21.

[0043] A replenishment cylinder 27 is provided on one side of the storage cylinder 21. The replenishment cylinder 27 stores medicine. A sealing cap is threaded on the upper medicine filling port of the replenishment cylinder 27. Medicine can be added into the replenishment cylinder 27 by opening the sealing cap. A support 211 is fixedly provided on the lower side of the replenishment cylinder 27. The support 211 and the mounting base 24 can be set on a supporting surface such as the ground. A second connecting pipe 28 is fixedly connected between the replenishment cylinder 27 and the storage cylinder 21. A second solenoid valve is installed on the side of the second connecting pipe 28 near the replenishment cylinder 27. The second connecting pipe 28 and the first connecting pipe 22 are set as a hose. A second delivery pump 29 is fixedly provided on the second connecting pipe 28. The second delivery pump 29 is fixed on the upper side of the support 211. A controller 210 is installed on one side of the tank body 11.

[0044] During dosing, the controller 210 can open the first solenoid valve on the first connecting pipe 22 and, through the first delivery pump 23, transport the agent in the storage tank 21 to the tank 11 via the first connecting pipe 22 to add coagulant to the tank 11. The pressure sensor 26 can detect the amount of agent used in the storage tank 21. As the agent in the storage tank 21 is used, the pressure detected by the pressure sensor 26 will gradually decrease. When replenishing the agent in the storage tank 21, the controller can operate the second delivery pump 29 and open the second solenoid valve on the second connecting pipe 28 to transport the agent in the replenishment tank 27 to the storage tank 21 via the second connecting pipe 28 to replenish the agent. When the pressure detected by the pressure sensor 26 reaches the set value, it indicates that the agent replenishment in the storage tank 21 is complete. The controller will then stop the second delivery pump 29 and close the second solenoid valve on the second connecting pipe 28.

[0045] The first adjusting component 3 includes a mounting shell 31 fixed to one side of the tank 11. A through hole is provided on the side of the mounting shell 31 for heat dissipation and a filter screen can be fixed inside the through hole to prevent the entry of external debris. A liquid level sensor 32 is installed on the upper side of the tank 11 to detect the wastewater level inside the tank 11. A turbidity sensor 33 is installed at the inlet pipe of the tank 11. A first adjusting component 34 is provided inside the mounting shell 31. The first adjusting component 34 includes a metal strip 341 fixed inside the mounting shell 31. A sliding plate 342 is slidably disposed on the outer side of the metal strip 341. A connecting block 343 is fixed on one side of the sliding plate 342 and slidably disposed with the bottom inner side of the mounting shell 31. Correspondingly, a connecting block 343 is provided at the bottom inner side of the mounting shell 31. The first limiting groove is adapted to the 43 phases. The connecting block 343 is slidably arranged along the first limiting groove, which can guide and limit the movement of the connecting block 343. A first electromagnetic block 344 fixed to the mounting shell 31 is provided on one side of the connecting block 343. A first magnetic block 345 repelling the first electromagnetic block 344 is fixed on one side of the connecting block 343. A first spring 346 fixed to the mounting shell 31 is fixed on the other side of the connecting block 343. The liquid level sensor 32 and the turbidity sensor 33 are electrically connected to the first electromagnetic block 344 of the first adjusting member 34. The metal strip 341 of the first adjusting member 34 is electrically connected to the motor 12, and the resistance value of the metal strip 341 on the side of the slider 342 away from the first electromagnetic block 344 is connected to the circuit.

[0046] When pesticide wastewater is transported into tank 11 through the inlet pipe, the liquid level inside tank 11 gradually rises. The controller 210 and the liquid level sensor 32 detect this rise, increasing the current in the circuit connected to the liquid level sensor 32. This increases the repulsive force of the first electromagnetic block 344 on the first magnetic block 345, causing the connecting block 343 to move the slider 342 away from the first electromagnetic block 344. The first spring 346 is compressed, reducing the resistance of the metal strip 341 in the circuit and decreasing the current in the connecting circuit. The increased stirring speed of the motor 12 driving the stirring element 13 can be increased, thus allowing the stirring speed to be adaptively adjusted according to the liquid level change when wastewater is introduced into the tank 11. Furthermore, the turbidity of the wastewater is detected by the turbidity sensor 33. When the turbidity of the wastewater detected by the turbidity sensor 33 is high, the current in the circuit connected to the turbidity sensor 33 will be relatively large, which can further increase the repulsive effect of the first electromagnetic block 344 on the first magnetic block 345, thereby further increasing the stirring speed and further improving the mixing effect with the reagent for wastewater with high turbidity.

[0047] The second regulating component 4 includes a four-way pipe 41 fixedly connected to the inlet pipe of the tank 11. Flow sensors 42 are installed at the three ends of the four-way pipe 41 away from the inlet pipe of the tank 11, and a third solenoid valve is installed at each of these three ends. A second regulating component 43 is provided inside the mounting housing 31. The second regulating component 43 has the same structure as the first regulating component 34. The metal strip 341 of the second regulating component 43 is electrically connected to the first delivery pump 23, and the resistance value of this metal strip 341 on the side of the slider 342 away from the first solenoid block 344 is connected to the circuit. The flow sensor 42 is electrically connected to the first electromagnetic block 344 of the second regulating component 43. The three ends of the four-way pipe 41 are used to transport different types of pesticide wastewater, such as organophosphorus pesticides, herbicides and insecticides. When one type of pesticide wastewater is input through one end of the corresponding four-way pipe 41, the flow sensor 42 on the corresponding end will detect the wastewater flowing in. Through the controller 210, the third electromagnetic valves on the other two ends will be closed, so that the wastewater enters the tank 11 through the inlet pipe of the tank 11.

[0048] When the wastewater flow rate detected by the flow sensor 42 is relatively fast, the current in the circuit connected to the flow sensor 42 will be relatively large. At this time, the wastewater enters the tank 11 at a relatively fast speed, which makes the repulsive effect of the first electromagnetic block 344 of the second regulating member 43 on the first magnetic block 345 relatively large. This causes the connecting block 343 of the second regulating member 43 to drive the sliding plate 342 away from the first electromagnetic block 344, making the resistance value of the metal strip 341 of the second regulating member 43 relatively small. This allows the power of the first delivery pump 23 to be relatively large, thereby increasing the dosing speed and timely treating the large amount of wastewater entering the tank, so as to adapt to each other and improve the treatment effect.

[0049] The control component 5 includes a first rack 51 fixedly disposed on one side of the connecting block 343 of the first adjusting member 34. The first rack 51 is slidably disposed with the bottom inner side of the mounting housing 31. Correspondingly, the bottom inner side of the mounting housing 31 is provided with a second limiting groove adapted to the first rack 51. The first rack 51 is slidably disposed along the second limiting groove, which can guide and limit the movement of the first rack 51. A first gear 52 is meshed and connected to one side of the first rack 51. A second gear 53 and a third gear 54 are respectively disposed on the upper side of the first gear 52. A support rod 55 is fixedly disposed in the middle of the first gear 52, the second gear 53 and the third gear 54. The end is rotatably mounted to the inner bottom of the mounting housing 31 via a bearing. The diameter of the third gear 54 is larger than the diameter of the second gear 53, and the diameter of the second gear 53 is larger than the diameter of the first gear 52. The first gear 52 is meshed with the second rack 56 on one side, the second gear 53 is meshed with the third rack 57 on one side, and the third gear 54 is meshed with the fourth rack 58 on one side. The second rack 56, the third rack 57, and the fourth rack 58 are slidably mounted on one side of the second rack 56, the third rack 57, and the fourth rack 58, and a guide plate 513 is fixed to the mounting housing 31. The guide plate 513 can support and guide the second rack 56, the third rack 57, and the fourth rack 58.

[0050] A connecting shell 59 is fixedly provided on one side of the second rack 56, the third rack 57, and the fourth rack 58. A second electromagnetic block 510 is fixedly provided inside the connecting shell 59. A tooth block 511 that is attracted to the second electromagnetic block 510 is slidably provided inside the connecting shell 59. A second spring 512 that is fixedly provided inside the connecting shell 59 is symmetrically fixed on one side of the tooth block 511. The second electromagnetic block 510 on the second rack 56 is electrically connected to the flow sensor 42 on the end of the four-way pipe 41 through which pesticide wastewater with low colloidal stability flows. The second electromagnetic block 510 on the third rack 57 is electrically connected to the flow sensor 42 on the end of the four-way pipe 41 through which pesticide wastewater with medium colloidal stability flows. The second electromagnetic block 510 on the fourth rack 58 is electrically connected to the flow sensor 42 on the end of the four-way pipe 41 through which pesticide wastewater with high colloidal stability flows.

[0051] A connecting member 514 is provided on one side of the connecting shell 59 and is slidably disposed on the bottom inner side of the mounting shell 31. A third limiting groove adapted to the connecting member 514 is provided on the bottom inner side of the mounting shell 31, and the connecting member 514 is slidably disposed along the third limiting groove. A fourth spring 522 is fixedly disposed on one side of the connecting member 514 and is fixedly disposed on the mounting shell 31, which can be used to reset the connecting member 514. A toothed groove adapted to the toothed block 511 is provided on one side of the connecting member 514. A mounting member 515 is slidably disposed on the connecting member 514. A touch switch 516 is installed on one side of the mounting member 515. The touch switch 516 is electrically connected to the first delivery pump 23. A third limiting groove is fixedly disposed on the inner side of the mounting shell 31. The third electromagnetic block 517 has a pressure block 518 that slides on one side of the third electromagnetic block 517 and is fitted with the bottom of the inner side of the mounting shell 31. The inner side of the mounting shell 31 has a fourth limiting groove that matches the pressure block 518. The pressure block 518 slides along the fourth limiting groove. One side of the pressure block 518 is set with an arc-shaped end face to facilitate contact with the touch switch 516. A second magnetic block 519 that repels the third electromagnetic block 517 is fixed on one side of the pressure block 518. A third spring 520 that is fixed to the inner side of the mounting shell 31 is fixed on the other side of the pressure block 518. The pressure sensor 26 is electrically connected to the third electromagnetic block 517. An alarm 521 is installed on one side of the tank body 11.

[0052] When the flow sensor 42 on the corresponding end of the four-way pipe 41 detects the introduction of pesticide wastewater with high colloidal stability, the controller 210 can de-energize the second electromagnetic block 510 on one side of the fourth rack 58. Under the elastic force of the second spring 512, the tooth block 511 on one side of the fourth rack 58 moves outward until it engages with the tooth groove of the connector 514. When the liquid level sensor 32 and the turbidity sensor 33 detect and the connecting block 343 of the first adjusting member 34 moves away from the first electromagnetic block 344, it can drive the first rack 51 to move, causing the first gear 52 to rotate, which in turn causes the support rod 55, the second gear 53 and the third gear 54 to rotate. Through the engagement of the tooth block 511 on one side of the fourth rack 58 with the connector 514, the first rack 51 moves, causing the first gear 52 to rotate, which in turn causes the support rod 55, the second gear 53 and the third gear 54 to rotate. When the device is fixed in place, the connecting piece 514 can move closer to the third electromagnetic block 517, so that the pressure block 518 no longer touches the touch switch 516. This will control the first delivery pump 23 to work and add the agent into the tank 11. This will reduce the pressure of the storage cylinder 21 detected by the pressure sensor 26, reduce the current in the circuit connected to the pressure sensor 26, and reduce the repulsive effect of the third electromagnetic block 517 on the second magnetic block 519. Under the elastic force of the third spring 520, the pressure block 518 moves closer to the third electromagnetic block 517. When the pressure block 518 moves to touch the touch switch 516, it will control the first delivery pump 23 to stop working and stop adding the agent. Thus, the dosage can be adaptively adjusted according to the wastewater volume and turbidity.

[0053] When the flow sensor 42 at the corresponding end of the four-way pipe 41 detects pesticide wastewater with moderate colloidal stability being introduced, it can de-energize the second electromagnetic block 510 on one side of the third rack 57, causing the tooth block 511 on one side of the third rack 57 to engage and fix with the tooth groove of the connector 514. The third rack 57 drives the movement of the connector 514 and the touch switch 516. Similarly, when the flow sensor 42 at the corresponding end of the four-way pipe 41 detects pesticide wastewater with low colloidal stability being introduced, it will de-energize the second electromagnetic block 510 on one side of the second rack 56, causing the second rack 56 to engage and fix with the tooth groove of the connector 514. One side of the toothed block 511 engages and is fixed with the connector 514. The connector 514 is moved by the second rack 56. By setting the gear ratio of the first gear 52, the second gear 53 and the third gear 54, for pesticide wastewater with high colloidal stability, the connector 514 will move a relatively large distance, so that the pressure block 518 will move a relatively large distance before it touches the touch switch 516, thereby increasing the dosage. Conversely, for pesticide wastewater with low colloidal stability, the dosage can be relatively small. Thus, the dosage can be further adjusted according to different types of pesticide wastewater.

[0054] After the coagulation process is completed, the corresponding toothed block 511 is engaged and fixed with the connector 514, which can drive the connector 514 to move in the opposite direction and reset. When the second delivery pump 29 is controlled to work and replenish the agent into the storage cylinder 21, the pressure sensor 26 detects that the pressure set value has been reached and stops replenishing the agent. At this time, the repulsive effect of the third electromagnetic block 517 on the second magnetic block 519 can move the pressure block 518 away from the third electromagnetic block 517 to the initial position, so that the pressure block 518 touches the touch switch 516. Then the alarm 521 will not issue an alarm. If the pressure block 518 does not touch the touch switch 516 after moving to the initial position, the alarm 521 will be controlled to issue an alarm to remind the staff to check the internal structure of the mounting shell 31 (the opening and closing of the mounting shell 31 and other related settings are existing public technologies).

[0055] Example 2

[0056] The control component 6 includes a third connecting pipe 61 that is fixedly connected to the drain port on the lower side of the tank 11. A fourth solenoid valve is installed on the third connecting pipe 61. The input end of the third delivery pump 62 is fixedly connected to one end of the third connecting pipe 61. The output end of the third delivery pump 62 is fixedly connected to the fourth connecting pipe 63. A fifth solenoid valve is installed on the fourth connecting pipe 63 on one side of the fifth connecting pipe 64. The fifth connecting pipe 64, which is fixedly connected to the tank 11, is fixedly connected to the fourth connecting pipe 63. A sixth solenoid valve is installed on the lower side of the fifth connecting pipe 64. An SCD instrument 65 is installed on the third connecting pipe 61.

[0057] A fourth electromagnetic block 66 is fixedly mounted on the upper side of the connector 514. A third magnetic block 67 that repels the fourth electromagnetic block 66 is fixedly mounted on one side of the mounting part 515. A fifth spring 68 that is fixed to the connector 514 is fixedly mounted on the other side of the mounting part 515. A fifth limiting groove that matches the mounting part 515 is provided on the upper side of the connector 514. The mounting part 515 is slidably mounted along the fifth limiting groove. The fourth electromagnetic block 66 is electrically connected to the SCD instrument 65.

[0058] After the initial coagulation of the wastewater, the second delivery pump 29 can be controlled to replenish the storage tank 21 to the initial dosage. The fourth solenoid valve on the third connecting pipe 61 is opened, and the third delivery pump 62 is activated, allowing the wastewater in tank 11 to be discharged through the third connecting pipe 61. The controller 210 and the SCD instrument 65 monitor the coagulated wastewater. When the flow current value detected by the SCD instrument 65 meets the requirements, the fifth solenoid valve on the fourth connecting pipe 63 is opened, and the sixth solenoid valve on the fifth connecting pipe 64 is closed, allowing the wastewater to be passed through the fourth connecting pipe 63 to the next processing stage. If the flow current value detected by the SCD instrument 65 exceeds the set threshold... When the value is high, it indicates poor coagulation effect. The fifth solenoid valve on the fourth connecting pipe 63 will be closed, and the sixth solenoid valve on the fifth connecting pipe 64 will be opened. The wastewater will be transported back to the tank 11 for treatment through the fifth connecting pipe 64. When the flow current value detected by the SCD instrument 65 is large, the repulsive effect of the fourth solenoid block 66 on the third magnetic block 67 will be relatively large. This will cause the mounting part 515 and the touch switch 516 to move a relatively large distance away from the fourth solenoid block 66. Based on the detection of the wastewater level by the liquid level sensor 32 and the detection of the SCD instrument 65, the dosage can be further adjusted to ensure the secondary coagulation effect and thus improve the treatment effect of the wastewater.
