Description

Technical Field

[0001] This utility model relates to the field of environmental governance technology, and more specifically, it relates to a device for Fenton oxidation and coagulation sedimentation. Background Technology

[0002] In the field of environmental governance, especially in water treatment, Fenton oxidation and coagulation sedimentation reactions are often used to remove organic pollutants and suspended solids from water. In the Fenton reaction, the addition of reactants such as hydrogen peroxide and iron salts is crucial, as they can effectively degrade organic pollutants in water. To ensure the high efficiency of the Fenton reaction, sufficient contact between chemical reagents and pollutants is critical. However, in existing technologies, it is usually difficult to precisely control the amount and flow rate of chemical reagents. This not only affects the efficiency of the reaction but may also lead to reagent waste or incomplete reaction, reducing the treatment effect. Therefore, a method or device is needed in the water treatment process to ensure the precise addition and mixing of chemical reagents and improve the efficiency of the Fenton reaction.

[0003] Similarly, in the coagulation and sedimentation process, the addition of coagulants and their thorough mixing with particulate matter in the water are also important steps in improving water quality. Coagulants react chemically with suspended solids in the water to form larger flocs, thereby removing particulate matter. However, in practical applications, due to the imprecise control of coagulant flow rate and volume, uneven contact between the coagulant and particulate matter in the water is often caused, which affects the sedimentation effect. Traditional coagulation and sedimentation systems often use a simple quantitative addition method, lacking effective adjustment of the coagulant dosage and reaction rate. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a device for Fenton oxidation and coagulation sedimentation, which has the following beneficial effects:

[0017] 1. The mixing mechanism of this equipment is ingeniously designed to effectively ensure that the chemical reagents in the Fenton oxidation and coagulation sedimentation processes come into full contact with the pollutants in the water, thereby improving the reaction efficiency. The mixing tank is driven by the rotation of the irregularly shaped stirring paddle, which drives the wastewater and chemical reagents to be strongly stirred in the tank, thereby promoting the full mixing of the reactants. The drive unit drives the stirring paddle to rotate by rotating the rotating rod, ensuring that the mixing process is uniform and efficient. In addition, during the rotation, the design of the stirring paddle allows the chemical reagents in the wastewater to be quickly and fully distributed in the entire reaction system. This not only helps to improve the oxidation effect of the Fenton reaction, but also improves the efficiency of coagulation sedimentation, thereby achieving the goal of optimizing the water treatment effect.

[0018] 2. The flow control mechanism precisely adjusts the amount and flow rate of chemical reagents added, ensuring accurate dosing of chemicals as needed during water treatment. Through the threaded connection of the adjusting sleeve and mating sleeve, the flow area and flow rate can be controlled by sliding between the connecting frame and the baffle plate, thus flexibly adjusting the flow rate of the reagents. This design not only improves the precise control of the amount of chemical reagents added but also avoids reagent waste or incomplete reactions. Furthermore, the flow control mechanism is simple and flexible to adjust, allowing operators to adjust the amount of chemical reagents added in real time according to different wastewater types and pollutant concentrations, thereby achieving more efficient water treatment.

[0019] 3. The design of the limiting mechanism effectively solves the stability problem in the adjustment process of the flow control mechanism. It ensures that the equipment can accurately maintain the required operating state when adjusting the flow rate of chemical reagents. After adjustment, the limiting sleeve and limiting block ensure that each component is firmly fixed after adjustment, thereby avoiding misoperation or accidental changes to the adjustment results and ensuring the stability of the reaction process. Through the unlocking mechanism, it is easy to readjust, ensuring the flexibility and adjustability of the equipment. In addition, the limiting mechanism, through the cooperation of the return spring and the push spring, can provide sufficient elasticity and damping effect during the adjustment process, further improving the accuracy and reliability of the adjustment system. This limiting design effectively ensures the precise control of the equipment in long-term operation, which helps to improve the service life of the equipment and the water treatment effect.

This limits the range of motion of each component and ensures its accurate positioning, thereby avoiding misoperation or positional errors during system adjustment and improving control accuracy.

[0035] The unlocking mechanism includes a rotating sleeve 29, an unlocking sleeve 30, and an unlocking groove 31. The rotating sleeve 29 rotates to adjust the outer wall of the connecting sleeve 8.

[0036] Each of the multiple sets of limiting blocks 25 is connected to a return spring 32 at its top end. The bottom ends of the multiple sets of return springs 32 are fixedly connected to the outer wall of the mounting ring 24. Each of the multiple sets of push rods 28 is provided with a push spring 33 on its outer wall. The top ends of the multiple sets of push springs 33 are fixedly connected to the bottom surface of the limiting sleeve 27 and the bottom ends abut against the unlocking sleeve 30. The function of the return springs 32 and push springs 33 is to provide restoring force for the limiting blocks 25 and the push rods 28, ensuring that each component can quickly return to its initial position after adjustment.

[0037] In this embodiment, wastewater is injected into the mixing tank 2 through the inlet hole 17. Then, the external chemical reagent delivery pipe is connected to the external pipe 23. The drive group 3 drives the rotating rod 4 to rotate, which in turn drives the mounting frame 5 and multiple sets of irregularly shaped stirring paddles 6 to rotate, thus mixing the wastewater and chemical reagents in the mixing tank 2. Subsequently, the pneumatic valve 19 controls the opening and closing of the discharge pipe to transport the wastewater to the subsequent sedimentation tank. When it is necessary to adjust the flow rate of the chemical reagent, the rotating anti-slip sleeve 22 drives the adjusting sleeve 9 to rotate. The adjusting sleeve 9 drives the mating sleeve 10 to rotate and engages with the screw 11 through the thread. This causes the screw 11 to move the connecting frame 12. The connecting frame 12 drives multiple sets of baffles 13 to slide along the control block 15 through the control groove 16, thereby controlling the multiple sets of baffles to undergo elastic deformation, thereby changing the flow area and flow rate of the chemical reagent, and thus adjusting the flow rate of the chemical reagent.

[0038] More specifically, after adjustment, multiple sets of push springs 33 push the limiting sleeve 27 against the top of multiple sets of limiting blocks 25, so that the bottom of the multiple sets of limiting blocks 25 are engaged in the limiting groove 26 and squeeze the multiple sets of return springs 32 to limit the adjustment sleeve 9. Multiple sets of push rods 28 abut against the top of the unlocking sleeve 30 to limit the limiting sleeve 27. When adjustment is required again, rotating the rotating sleeve 29 drives the unlocking sleeve 30 to rotate. The unlocking sleeve 30 drives the multiple sets of unlocking holes to the bottom of the push rods 28 to release the limitation on the limiting sleeve 27. Sliding the limiting sleeve 27 allows the multiple sets of push rods 28 to be inserted into the unlocking holes and compress the push springs 33 to release the abutment of the limiting sleeve 27 against the multiple sets of limiting blocks 25. The return springs 32 pull the limiting blocks 25 so that their bottom ends are disengaged from the limiting groove 26, releasing the limitation on the adjustment sleeve 9.

[0039] In summary, during use or operation of the overall equipment: In use, wastewater is injected into the mixing tank 2 through the inlet 17. Then, the external chemical reagent delivery pipe is connected to the external pipe 23. The drive unit 3 drives the rotating rod 4 to rotate, which in turn drives the mounting frame 5 and multiple sets of irregularly shaped stirring paddles 6 to rotate, mixing the wastewater and chemical reagents in the mixing tank 2. Subsequently, the pneumatic valve 19 controls the opening and closing of the discharge pipe to transport the wastewater to the subsequent sedimentation tank. When it is necessary to adjust the flow rate of the chemical reagents, the rotating anti-slip sleeve 22 drives the adjusting sleeve 9 to rotate. The adjusting sleeve 9 drives the mating sleeve 10 to rotate and engages with the screw 11, causing the screw 11 to move the connecting frame 12. The connecting frame 12 then drives multiple sets of baffles 13 to slide along the control block 15 through the control groove 16, thereby controlling the elastic deformation of the multiple baffles to change the flow area and velocity of the chemical reagents, thus adjusting the flow rate of the chemical reagents.

[0040] After adjustment, multiple sets of push springs 33 push the limiting sleeve 27 against the top of multiple sets of limiting blocks 25, so that the bottom of the multiple sets of limiting blocks 25 are engaged in the limiting groove 26 and squeeze the multiple sets of return springs 32 to limit the adjustment sleeve 9. Multiple sets of push rods 28 abut against the top of the unlocking sleeve 30 to limit the limiting sleeve 27. When adjustment is required again, rotating the rotating sleeve 29 drives the unlocking sleeve 30 to rotate. The unlocking sleeve 30 drives the multiple sets of unlocking holes to the bottom of the push rods 28 to release the limitation of the limiting sleeve 27. Sliding the limiting sleeve 27 allows the multiple sets of push rods 28 to be inserted into the unlocking holes and compress the push springs 33 to release the abutment of the limiting sleeve 27 against the multiple sets of limiting blocks 25. The return springs 32 pull the limiting blocks 25 so that their bottom ends are disengaged from the limiting groove 26, releasing the limitation of the adjustment sleeve 9.
