Description

Technical Field

[0001] This invention relates to the field of wastewater purification and treatment equipment, specifically a high-efficiency purification and treatment device for glyphosate production wastewater. Background Technology

[0002] Glyphosate is a systemic, broad-spectrum, non-selective herbicide that primarily works by inhibiting enolpyruvylshikimate phosphate synthase in plants, thereby inhibiting the conversion of shikimate to phenylalanine, tyrosine, and tryptophan. This disrupts protein synthesis and leads to plant death. Glyphosate is mainly used to control grassy and broadleaf weeds, suitable for inter-row weeding in orchards, tea plantations, rubber plantations, sugarcane fields, and no-till crops such as rice paddies and wheat fields. It is also used for weeding in forests and firebreaks, railway and airport areas, highways, and grassland improvement. Furthermore, it can be used for weed control in glyphosate-tolerant genetically modified crops such as soybeans, cotton, corn, and rapeseed.

[0003] Chinese patent CN117003300A discloses a pesticide production wastewater treatment device. Addressing the problems of existing filter plates easily clogging and uneven contact between the neutralizing agent and wastewater, thus affecting treatment efficiency, the following solution is proposed: It includes a neutralization tank, a filter tank fixedly installed on one side of the neutralization tank, and a pesticide tank fixedly installed on the other side. The filter tank and the neutralization tank are connected by a common connecting pipe. A filter plate with multiple filter holes is fixedly installed inside the filter tank. The filter tank is equipped with a clearing mechanism. A rotating hole is opened at the top of the neutralization tank. This solution, through the operation of a motor, can agitate the pesticide production wastewater, transport the neutralizing agent, and clear the filter plate, ensuring more even contact between the neutralizing agent and the pesticide production wastewater, clearing the filter holes, preventing clogging, and maintaining filtration efficiency.

[0004] When treating glyphosate production wastewater, it is generally necessary to neutralize the wastewater with reagents. As shown in the aforementioned patent, existing wastewater treatment devices typically filter the wastewater before feeding it into a neutralization tank. Inside the neutralization tank, agitators stir the wastewater and reagents to mix and react with the wastewater. This mixing process takes a certain amount of time, and the treated wastewater can only be discharged after mixing is complete. This method cannot continuously treat wastewater. Furthermore, the impurities filtered through the filtration structure require frequent manual cleaning, which cannot remove the filtered impurities quickly and promptly, making the filtration structure prone to clogging.

[0005] Therefore, it is necessary to provide a high-efficiency purification and treatment device for glyphosate production wastewater to solve the above-mentioned technical problems. Summary of the Invention

The lower baffle plate can push the filter cylinder upward, causing the middle part of the elastic plate to bulge upward, so that the cleaned impurities can flow outward with the cleaning water and be discharged through the impurity discharge hopper. During normal filtration, the elastic plate is in a downward concave state, so that the wastewater can flow towards the filter cylinder, which can automatically clean the filter cylinder and discharge the cleaned impurities in time, thereby reducing the probability of filter cylinder clogging.

[0020] 3. The present invention, through the arrangement of the upper baffle, elastic sealing component, and water injection component, enables the upper baffle to not only seal the bottom ends of the wastewater input pipe and the chemical input pipe when it moves upward, thus stopping the input of wastewater and chemicals, but also to drive the valve to open through the slide cylinder and rack, allowing the clean water output from the clean water input pipe to enter the cavity through the outlet hole, and allowing the clean water to be dispersed and output through the inclined hole. The second spring enables the slide cylinder to move downward and close the valve when the upper baffle separates from the slide cylinder, thus automatically opening and closing the valve. The slide cylinder not only drives the valve to open and close, but also protects the outlet hole of the clean water input pipe, preventing wastewater from entering the outlet hole.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Please see Figures 1-7In this embodiment of the invention, a high-efficiency purification and treatment device for glyphosate production wastewater includes a neutralization tank 1 and a filter tank 2. Both the neutralization tank 1 and the filter tank 2 are cylindrical structures. The filter tank 2 is fixedly installed at the top of the neutralization tank 1 and is connected to the neutralization tank 1. Multiple partitions 19 are fixedly installed inside the neutralization tank 1. Through grooves 1901 are formed on the partitions 19, and the multiple through grooves 1901 are staggered. A rotating shaft 17 is rotatably installed inside the neutralization tank 1. A motor 16 is fixedly installed at the bottom of the neutralization box 1. The output end of the motor 16 is fixedly connected to the bottom end of the rotating shaft 17. Multiple partitions 19 divide the inner cavity of the neutralization box 1 into multiple chambers. Each chamber is equipped with a stirring blade 18, which is fixedly connected to the rotating shaft 17. The top of the filter box 2 is connected to a reagent inlet pipe 14 and a wastewater inlet pipe 13. A filtration mechanism is provided inside the filter box 2. The bottom of the neutralization box 1 is connected to a drain outlet 21. A pH sensor is installed to monitor the pH value of the output wastewater in real time, so as to adjust the input amount of the reagent in a timely manner. In actual use, the wastewater is fed into the filter box 2 through the wastewater inlet pipe 13. After the impurities in the wastewater are filtered by the filter mechanism in the filter box 2, the wastewater enters the interior of the neutralization box 1. The rotating shaft 17 is driven by the motor 16 to rotate. When the rotating shaft 17 rotates, it drives multiple stirring blades 18 to rotate. The wastewater entering the neutralization box 1 gradually flows downward through the through grooves 1901 on the partition 19. During the flow, the stirring blades 18 stir the wastewater and the reagent to ensure that the wastewater and the reagent are fully mixed. Finally, it is discharged through the drain outlet 21. By setting multiple partitions 19, the interior of the neutralization box 1 is divided into multiple chambers. Each chamber is equipped with stirring blades 18, which has a good mixing effect on wastewater and reagent. The wastewater gradually flows downward through the through grooves 1901 on the partition 19. The staggered through grooves 1901 lengthen the flow path of the wastewater and improve the mixing effect of wastewater and reagent.

[0032] In this embodiment, preferably, the filtration mechanism includes an mounting ring 3, an elastic disc 4, a filter cylinder 5, and an upper baffle 6. The filter cylinder 5 has multiple vertically arranged filter slits 501 on its wall. The top openings of the filter slits 501 are sealed by the upper baffle 6. The mounting ring 3 is fixedly installed inside the filter box 2. The elastic disc 4 is fixedly installed inside the mounting ring 3. A through hole is provided in the center of the elastic disc 4. The filter cylinder 5 is fixedly installed inside the through hole. The elastic disc 4 is made of elastic rubber. The upper baffle 6 is positioned at the top of the filter cylinder 5 to seal the opening at the top of the filter cylinder 5. During filtration, the elastic disc 4 is recessed downwards, allowing water entering the filter box 2 to flow more easily into the filter cylinder 5. When cleaning the filter cartridge 5, the elastic disc 4 protrudes upward, making it easier for impurities cleaned from the filter cartridge 5 to move outward from the surface of the elastic disc 4. A connecting column 7 is fixedly installed at the bottom end of the upper baffle 6, and a lower baffle 8 is installed at the bottom end of the connecting column 7. A flange 802 is provided on the bottom edge of the lower baffle 8. When the flange 802 contacts the bottom wall of the filter cartridge 5, it can drive the filter cartridge 5 to move upward. A cleaning disc 9 is fixedly installed in the middle of the rotating shaft 17 through a connecting block 10. Multiple cleaning blocks 11 are fixedly installed on the outer peripheral wall of the cleaning disc 9. The multiple cleaning blocks 11 are respectively arranged in multiple filter slots 501. When the cleaning block 11 moves to the top of the filter slot 501, The lower baffle 8 seals the bottom opening of the filter cylinder 5. A cylinder 12 is fixedly installed at the top of the filter box 2, and the output end of the cylinder 12 extends into the interior of the filter box 2 and is fixedly connected to the upper baffle 6. The bottoms of the wastewater inlet pipe 13 and the chemical inlet pipe 14 both extend into the interior of the filter box 2. When cleaning the filter cylinder 5, the upper baffle 6 moves upward to seal the bottom openings of the wastewater inlet pipe 13 and the chemical inlet pipe 14. When filtering the wastewater entering the filter box 2, the wastewater flows downward through the gap between the filter slit 501 and the connecting block 10 in the middle of the cleaning disc 9, and enters the neutralization box 1 for neutralization. Impurities in the wastewater are filtered through the filter slit 501, and the impurities remain on the surface of the elastic disc 4. A small amount of impurities are stuck inside the filter gap 501. When cleaning the filter cylinder 5, the cylinder 12 drives the upper baffle 6 to move upward. The upper baffle 6 drives the cleaning disc 9 and the lower baffle 8 to move upward, so that the cleaning block 11 moves upward, thereby cleaning the filter gap 501 on the filter cylinder 5. In addition, the lower baffle 8 seals the opening at the bottom of the filter cylinder 5, so that when the filter cylinder 5 is cleaned with water later, the cleaning water will not flow downward into the neutralization box 1. During cleaning, after the flange 802 of the lower baffle 8 contacts the filter cylinder 5, the lower baffle 8 can push the filter cylinder 5 to move upward, so that the middle part of the elastic disc 4 bulges upward, allowing the cleaned impurities to flow outward with the cleaning water.

[0033] In this embodiment, preferably, the lower baffle 8 is rotatably connected to the bottom end of the connecting column 7. The top of the lower baffle 8 is provided with multiple annular protrusions 801 of different diameters, and the height of the annular protrusions 801 gradually decreases from the inside to the outside. The top of the rotating shaft 17 is fixedly installed with a transmission disk 20, and the top of the transmission disk 20 is provided with a rubber disk 2001. When the rubber disk 2001 contacts the lower baffle 8, the rotating shaft 17 drives the lower baffle 8 to rotate through the transmission disk 20, so that the wastewater and reagents flowing down from the inside of the cleaning disk 9 fall onto the lower baffle 8. The rotation of the lower baffle 8 causes the wastewater and reagents to disperse and splash outward under the action of centrifugal force, so that the wastewater and reagents are dispersed into small water droplets, thereby enabling the wastewater and reagents to be dispersed in the neutralization box 1. The setting of multiple annular protrusions 801 of different heights enables the wastewater and reagents to be dispersed outward from different heights, thereby improving the dispersion effect and improving the mixing efficiency.

[0034] In this embodiment, preferably, the filter box 2 has multiple discharge ports 201 on its wall, and multiple discharge hoppers 31 are fixedly installed on the outer peripheral wall of the filter box 2. The discharge hoppers 31 are connected to the discharge ports 201. A sealing cylinder 32 for sealing the discharge ports 201 is slidably arranged inside the filter box 2. The outer peripheral wall of the sealing cylinder 32 is in contact with the inner peripheral wall of the filter box 2. The upper baffle 6 is fixedly connected to the sealing cylinder 32 through a connecting rod 33. When cleaning impurities on the filter cylinder 5, the upper baffle 6 drives the sealing cylinder 32 to move upward through the connecting rod 33, so that the discharge ports 201 open. This allows the clean water flowing outward along the surface of the elastic disc 4 to flow outward along with the impurities and be discharged through the discharge ports 201 and the discharge hoppers 31. A collection device can be set at the outlet of the discharge hopper 31 for collection, or the water can be discharged through a pipe.

[0035] Please see Figure 8 In this embodiment of the invention, the upper baffle 6 has a cavity 601 inside, and the bottom wall of the upper baffle 6 has a plurality of inclined holes 602 that communicate with the cavity 601. The bottom opening of the inclined holes 602 is inclined away from the axis of the upper baffle 6, and then towards the cleaning block 11 to flush away the impurities pushed out by the cleaning block 11. The top of the filter box 2 is provided with a water injection component for injecting cleaning water into the cavity 601. The middle part of the top of the upper baffle 6 has an injection port that communicates with the inside of the cavity 601. The cavity 601 is provided with an elastic sealing component for sealing the injection port.

[0036] In this embodiment, preferably, the elastic sealing assembly includes a plug 22 and a first spring 23. The bottom end of the first spring 23 is fixedly connected to the bottom inner wall of the cavity 601, and the top end of the first spring 23 is fixedly connected to the plug 22. The plug 22 is adapted to the injection port.

[0037] In this embodiment, preferably, the water injection assembly includes a clean water inlet pipe 15, the bottom end of which is a closed structure. The clean water inlet pipe 15 is connected to a water source. A valve is provided on the clean water inlet pipe 15, and multiple water outlet holes 1501 are opened on the bottom wall of the clean water inlet pipe 15. A slide cylinder 29 is sleeved on the bottom end of the clean water inlet pipe 15, and a second spring 30 is fixedly connected to the top end of the slide cylinder 29. The top end of the second spring 30 is fixedly connected to the valve, specifically, the top end of the second spring 30 is fixedly connected to the valve housing 24. The valve includes a valve housing 24. The valve housing 24 is mounted on the clean water inlet pipe 15. A valve ball 25 is rotatably mounted inside the valve housing 24 via a connecting shaft 26. A connecting hole is provided in the center of the valve ball 25. The connecting shaft 26 is fixedly connected to the valve ball 25. One end of the connecting shaft 26 extends out of the valve housing 24, and a gear 27 is fixedly mounted on that end. A rack 28 is fixedly mounted on one side of the slide cylinder 29, and the rack 28 meshes with the gear 27. When the upper baffle 6 moves upward, it seals the bottom ends of the wastewater inlet pipe 13 and the chemical inlet pipe 14. The bottom end of the clean water inlet pipe 15 pushes open the plug 22 and extends into the cavity 601. This connects the outlet 1501 to the cavity 601. Furthermore, the slide cylinder 29 moves upward under the pushing action of the upper baffle 6, thereby pushing the rack 28 upward to drive the gear 27 to rotate. When the gear 27 rotates, it drives the valve ball 25 to rotate via the connecting shaft 26, opening the valve. This allows the clean water input through the clean water input pipe 15 to flow into the cavity 601 through the outlet 1501 and then out through the inclined hole 602. This solution, through the arrangement of the upper baffle 6, the elastic sealing assembly, and the water injection assembly, ensures that when the upper baffle 6 moves upward, it not only blocks the bottom of the wastewater input pipe 13 and the chemical input pipe 14, but also... The end is closed, stopping the input of wastewater and chemicals. It can also drive the valve to open through the slide cylinder 29 and rack 28, so that the clean water output from the clean water input pipe 15 enters the cavity 601 through the water outlet 1501, and the clean water is dispersed and output through the inclined hole 602. The second spring 30 can cause the slide cylinder 29 to move downward to close the valve when the upper baffle 6 is separated from the slide cylinder 29, thus automatically opening and closing the valve. The slide cylinder 29 can not only drive the valve to open and close, but also protect the water outlet 1501 of the clean water input pipe 15 to prevent wastewater from entering the water outlet 1501.

[0038] Working principle: Wastewater is input through wastewater inlet pipe 13, and neutralizing agent is input through agent inlet pipe 14. The agent and wastewater are filtered through filter cylinder 5 and then enter the interior of neutralization tank 1. The motor 16 drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it drives multiple stirring blades 18 to rotate. The wastewater entering the neutralization tank 1 gradually flows downward through the through groove 1901 on the partition 19. During the flow, the stirring blades 18 stir the wastewater and the agent to make them fully mixed. The neutralized wastewater is finally discharged through drain outlet 21.

[0039] After a period of use, the output end of the control cylinder 12 retracts once to clean the filter cartridge 5. When the output end of the control cylinder 12 retracts, it drives the upper baffle 6 to move upward. The upper baffle 6 drives the cleaning disc 9 and the lower baffle 8 to move upward, so that the cleaning block 11 moves upward, thereby cleaning the filter gap 501 on the filter cartridge 5. In addition, the lower baffle 8 closes the opening at the bottom of the filter cartridge 5, so that when the filter cartridge 5 is cleaned with water later, the cleaning water will not flow downward into the neutralization box 1. During cleaning, after the flange 802 of the lower baffle 8 contacts the filter cartridge 5, the lower baffle 8 can push the filter cartridge 5 to move upward, so that the middle part of the elastic disc 4 bulges upward, so that the cleaned impurities can flow outward with the cleaning water. After the impurities are rinsed, the output end of the control cylinder 12 extends to reset the upper baffle 6 and make the middle part of the elastic disc 4 concave downward, so that the wastewater flows towards the filter cartridge 5.

[0040] Furthermore, when the upper baffle 6 moves upward, it seals the bottom ends of the wastewater inlet pipe 13 and the chemical inlet pipe 14. The bottom end of the cleaning water inlet pipe 15 pushes open the plug 22 and extends into the cavity 601, so that the outlet hole 1501 is connected to the cavity 601. The slide cylinder 29 moves upward under the pushing action of the upper baffle 6, thereby pushing the rack 28 to move upward, so as to drive the gear 27 to rotate. When the gear 27 rotates, it drives the valve ball 25 to rotate through the connecting shaft 26, so that the valve opens, and then the cleaning water input through the cleaning water inlet pipe 15 flows into the cavity 601 through the outlet hole 1501, and then outputs through the inclined hole 602 to rinse the filter cylinder 5 and the cleaning block 11.
