Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a reagent addition device for wastewater treatment based on the Fenton oxidation method. Background Technology

[0002] Fenton oxidation wastewater treatment typically uses a reagent dosing device to achieve precise reagent addition. This device works by automatically adding the required reagents according to the proportion, time, and rate of the wastewater treatment system to achieve efficient water treatment. Different designs and models of this device can be selected according to specific needs to ensure accurate reagent dosing during wastewater treatment.

[0003] When the reagent dosing device for wastewater treatment in the Fenton oxidation process sprays the reagent material into the wastewater treatment tank through a spray plate, the spraying range is usually limited. The design and arrangement of the spray plate will affect the spraying range of the reagent, making it impossible for the wastewater inside the wastewater treatment tank to come into rapid contact with the reagent. Utility Model Content

[0004] The purpose of this invention is to provide a reagent addition device for wastewater treatment based on the Fenton oxidation method, which has the advantages of using paddles to disperse the sprayed material and adjusting the spraying range of the material according to the actual situation, thus solving the problem of the small spraying range of the reagent addition device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment reagent addition device based on the Fenton oxidation method, comprising a material box, bearings II embedded on both sides of the material box, fixing rods fixedly installed on the inner rings of the two sets of bearings II, a toothed disc installed at one end of each of the two fixing rods, a quantitative conveyor installed at the bottom of the material box, a fixing plate welded to the bottom of the material box on one side of the quantitative conveyor, bearing I embedded in the fixing plate, a fixing roller fixedly installed on the inner ring of bearing I, and blades installed in a circular array on the outer side of the fixing roller.

[0006] Preferably, a feed pipe is embedded on both sides of the top of the material box, and an observation window is embedded on the rear side of the material box.

[0007] Preferably, a motor is installed on the side of the material box, and the motor transmission structure is fixedly connected to a toothed disc on the side of the material box, with the two toothed discs meshing together.

[0008] Preferably, the two fixing rods are arranged in a circular array on the outer side of a section inside the material box.

[0009] Preferably, the fixed roller is movably connected to the fixed rod via a belt.

[0010] Preferably, the quantitative conveyor is equipped with a suction pipe at the top, which extends into the material box from the bottom. A discharge pipe is installed at the bottom of the material box, and a spray plate is installed at the bottom of the discharge pipe.

[0011] Preferably, the fixed roller has a movable hole that corresponds to the spray plate.

[0012] Preferably, a fixing frame is welded to the front side of the material box, and the fixing frame is arranged in a rectangular array with fixing holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up a belt and a fixed roller, allows two fixed rods to drive the stirring rod to rotate in opposite directions to mix the material inside the hopper. The fixed rods, via the belt, can drive the fixed roller to rotate, which in turn drives the paddle to rotate. A quantitative conveyor transports the material to the spray plate through the discharge pipe. The spray plate sprays the material downwards into the wastewater treatment tank. The rotating paddle disperses the sprayed material, causing it to splash outwards. When the fixed roller is not rotating, the material sprayed from the spray plate can pass through the movable holes of the fixed roller and fall into the wastewater treatment tank. This achieves the effect of using the paddle to disperse the sprayed material and adjusting the spraying range according to the actual situation. Attached Figure Description

[0024] Example 1

[0025] like Figures 1-4As shown, this utility model proposes a reagent addition device for wastewater treatment based on the Fenton oxidation method, including a material tank 3. Feed pipes 4 are embedded on both sides of the top of the material tank 3, and an observation window 6 is embedded on the rear side of the material tank 3. The reagent material enters the material tank 3 through the two feed pipes 4, storing the reagent material. The material level inside the material tank 3 can be observed through the observation window 6. Bearings 15 are embedded on both sides of the material tank 3, and fixing rods 16 are fixedly installed on the inner rings of both sets of bearings 15. A gear plate 7 is installed at one end of each fixing rod 16. A motor 5 is installed on the side of the material tank 3. The motor 5 is fixedly connected to a toothed disc 7 on the side of the material box 3 via a transmission structure. The two toothed discs 7 are meshed together. The motor 5 can drive one toothed disc 7 to rotate through the transmission structure, and the toothed disc 7 drives the other toothed disc 7 to rotate in the opposite direction. Two fixed rods 16 are located inside the material box 3, and stirring rods 20 are installed in a circular array on the outer side of each section. The two toothed discs 7 drive the two fixed rods 16 to rotate in opposite directions. The two fixed rods 16 drive the stirring rods 20 to mix and stir the pharmaceutical materials inside the material box 3. A metering conveyor 9 is installed at the bottom of the material box 3, and a suction device is installed at the top of the metering conveyor 9. The feed pipe 8 extends from the bottom of the material box 3 into its interior. A discharge pipe 10 is installed at the bottom of the material box 3, and a spray plate 11 is installed at the bottom of the discharge pipe 10. The metering conveyor 9 draws the pharmaceutical material from inside the material box 3 through the feed pipe 8, and then conveys the pharmaceutical material to the spray plate 11 through the discharge pipe 10. The spray plate 11 sprays the material downwards into the wastewater treatment tank. A fixing plate 1 is welded to the bottom of the material box 3 on one side of the metering conveyor 9. A bearing 14 is embedded in the fixing plate 1, and a fixing roller 12 is fixedly installed on the inner ring of the bearing 14. The fixing roller 12 is movable to the fixing rod 16 via a belt 2. The connection is that when the fixed rod 16 rotates, it can drive the fixed roller 12 to rotate via the belt 2. The fixed roller 12 has blades 13 installed in a ring array on its outer side. The fixed roller 12 has movable holes 17, which correspond to the spray plate 11. The chemical material sprayed by the spray plate 11 can pass through the movable holes 17 of the fixed roller 12 and fall into the wastewater treatment tank. The front side of the material box 3 is welded with a fixed frame 18. The fixed frame 18 has fixed holes 19 in a rectangular array. The fixed frame 18 is fixed to the load-bearing structure at the top of the wastewater treatment tank through the fixed holes 19 of the fixed frame 18 using bolts and other tools.

[0026] Working principle: The fixing frame 18 is fixed to the supporting structure at the top of the wastewater treatment tank using bolts or other tools through the fixing holes 19. The chemical materials enter the material tank 3 through the two feed pipes 4, where the material tank 3 stores the chemical materials. The motor 5 drives one gear disc 7 to rotate via a transmission structure. The gear disc 7 drives the other gear disc 7 to rotate in the opposite direction. The two gear discs 7 drive the two fixing rods 16 to rotate in opposite directions. The two fixing rods 16 drive the stirring rod 20 to mix and stir the chemical materials inside the material tank 3. After the process is completed, the quantitative conveyor 9 sucks up the medicine material inside the material box 3 through the suction pipe 8, and then conveys the medicine material to the spray plate 11 through the discharge pipe 10. The spray plate 11 sprays the material downward. The medicine material sprayed by the spray plate 11 passes through the movable hole 17 of the fixed roller 12 and falls into the wastewater treatment tank. When it is necessary to expand the medicine delivery range, the fixed rod 16 drives the fixed roller 12 to rotate through the belt 2. The fixed roller 12 drives the paddle 13 to rotate. The paddle 13 disperses the medicine material sprayed by the spray plate 11, so that the medicine material splashes outward and falls into the wastewater treatment tank.
