Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to an activated carbon dosing device for water treatment. Background Technology

[0002] Activated carbon, with its well-developed pore structure and abundant surface functional groups, has become an indispensable and highly efficient adsorption material in the field of water treatment. Whether it's removing natural organic matter, odors, and micropollutants in drinking water treatment, degrading recalcitrant organic matter and heavy metal ions in industrial wastewater, or improving effluent quality in advanced wastewater treatment, activated carbon demonstrates extremely high application value. With increasingly stringent environmental standards and the growing complexity of pollutants, activated carbon, due to its environmentally friendly, efficient, and renewable characteristics, is being widely used in waterworks, wastewater treatment plants, and various industrial wastewater treatment processes.

[0003] Activated carbon is often used in water treatment. Currently, the process involves adding activated carbon to a stirred tank to agitate the water. However, when activated carbon is added to the tank, it tends to concentrate at a single point. If the agitation is insufficient, this can create a localized area of ​​high concentration. In this case, pollutants in the water (such as organic matter and heavy metals) may be rapidly adsorbed, but in other areas, the low concentration of activated carbon weakens the adsorption effect, leading to a decrease in overall treatment efficiency.

Detailed Implementation

[0043] 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.

[0044] Please see Figure 1-7As shown, an activated carbon dosing device for water treatment includes a dosing device consisting of a storage tank 100, an auger conveyor 200, and a stirring device 300. The stirring device 300 includes a mixing tank 310 installed on the ground and communicating with the discharge pipe of the auger conveyor 200. A feeding section 320 is installed inside the mixing tank 310. The feeding section 320 includes a distributing component 321 located at the top of the inner cavity of the mixing tank 310. A fixing plate 322 is installed at one end of the distributing component 321, and a feeding hopper 323 is fixed at the other end of the fixing plate 322. A connecting pipe 324 connects the feeding hopper 323 to the bottom of the discharge pipe of the auger conveyor 200. The connecting pipe 324 is a retractable flexible hose, and its extension length is greater than the deflection distance of the fixing plate 322, so that when the feeding hopper 323 deflects, it will not damage the connecting pipe 324. The mixing tank 310 is equipped with a force-applying component 330 above it. The force-applying component 330 includes a force-applying rod 331 fixed to one end of the shaft of the auger conveyor 200. The other end of the force-applying rod 331 is hinged to one end of the push rod 332. A universal ball 333 is movably connected inside the other end of the connecting plate 3213. A connecting block 334 is fixed to the top of the universal ball 333. One side of the connecting block 334 is rotatably connected to the other end of the push rod 332. As the shaft inside the auger conveyor 200 rotates, it will drive the force-applying rod 331 to rotate, and at the same time drive the push rod 332 to rotate, and apply force to the connecting plate 3213 to facilitate subsequent feeding. The auger conveyor 200 realizes the rotation of the feeding part 320 through rotational force and the transmission of the force-applying component 330. An aeration component 340 is installed at the conical position inside the mixing tank 310.

[0045] Based on the above scheme, when uniform material distribution is required, the material distribution component 321 includes gears 3211 rotatably connected to both sides of the top of the inner cavity of the mixing tank 310. The bottom of the gears 3211 is fixed to one end of the fixing plate 322. Both sides of the surface of the mixing tank 310 slide through the rack plate 3212. The opposite side of the rack plate 3212 meshes with one side of the gear 3211. One end of the rack plates 3212 on both sides is fixedly connected to a connecting plate 3213. When the rack plate 3212 slides through the inside of the mixing tank 310, as the rack plate 3212 meshes with the gear 3211, it will drive the gear 3211 to rotate, and drive the fixing plate 322 and the feeding hopper 323 to deflect at an angle, thereby achieving the effect of uniform material distribution.

[0046] See Figure 5To facilitate better water treatment, during the mixing process, the filtered air is compressed by the Roots blower 341 and delivered to the interior of the circular tube 343 through the air blowing pipe 342. Then, the aerator 344 generates bubbles inside the mixing tank 310. The shear force generated when the bubbles break further breaks up carbon particle agglomeration, while simultaneously improving solid-liquid contact efficiency and further enhancing mixing efficiency. The aeration component 340 includes a Roots blower 341 installed on the left side of the mixing tank 310. The outlet end of the Roots blower 341 is connected to the air blowing pipe 342. The circular tube 343 is fixed at the conical position inside the mixing tank 310. The other end of the air blowing pipe 342 penetrates the interior of the mixing tank 310 and is connected to one side of the circular tube 343. The aerator 344 is fixedly arranged around the inner surface of the circular tube 343, and there is a certain distance between the aerator 344 and the stirring rod inside the mixing tank 310.

[0047] Based on the above scheme, see Figure 5 The reciprocating component 350 includes a movable plate 351 hinged to one side of the rack plate 3212. Folded rods 352 slide through both sides of the top of the mixing tank 310. The downward sliding distance of the folded rods 352 is the same as the moving distance of the rack plate 3212. Thus, when the rack plate 3212 moves, it applies force to the folded rods 352 through the movable plate 351. The other end of the movable plate 351 is rotatably connected to one side of the folded rods 352. A cleaning disc 353 is fixed to the other end of the folded rods 352. The outer surface of the cleaning disc 353 is surrounded by... Several nylon brushes 354 are fixed, and the positions of the nylon brushes 354 correspond one-to-one with those of the aerators 344. The number of nylon brushes 354 is greater than the size of the aerators 344. The cleaning disc 353 moves to better clean the surface of the aerators 344. As the rack plate 3212 slides, it applies force to the moving plate 351, thereby driving the folding rod 352 to slide, so as to drive the cleaning disc 353 and the nylon brushes 354 to clean the surface of the aerators 344, so as to facilitate better aeration in the future.

[0048] Both sides of the surface of the mixing tank 310 are fixed with fixing rods 400. The interior of the connecting plate 3213 slides through the surface of the fixing rods 400. This arrangement can provide auxiliary support for the connecting plate 3213 and maintain its stability during movement.

[0049] Movable rods 500 are fixed on both sides of the top rear of the cleaning disc 353. The movable rods 500 slide through the top of the mixing tank 310. As the cleaning disc 353 moves, the movable rods 500 slide through the top of the mixing tank 310, thereby providing auxiliary support for the cleaning disc 353 and improving its stability during movement.

[0050] Working Principle: During use, as water is supplied to the mixing device 300 via the water pipe, activated carbon is conveyed from the storage tank 100 to the mixing tank 310 via the auger conveyor 200 for mixing. During the feeding process, the rotation of the auger conveyor 200 shaft drives the force rod 331 to rotate, applying force to the push rod 332. Simultaneously, the universal ball 333 pulls the connecting plate 3213. As the connecting plate 3213 moves, it drives the rack plate 3212 to slide, causing the gear 3211 meshing with it to rotate. This, in turn, causes the fixed plate 322 and the feeding hopper 323 to deflect, thus evenly distributing the material inside the mixing tank 310. During the distributing process, the material is stirred by the agitator inside the mixing tank 310. The mixing structure can mix the falling activated carbon and water. To improve the mixing effect, the Roots blower 341 can be started to compress the filtered air and deliver it to the inside of the circular tube 343 through the air blowing pipe 342. Then, the aerator 344 generates bubbles inside the mixing tank 310. The shear force generated when the bubbles break can further break up the carbon particle agglomeration and improve the solid-liquid contact efficiency, thereby further improving the mixing efficiency. When the rack plate 3212 moves through the tank, it will apply force to the moving plate 351 and drive the folded rod 352 to slide downward. At the same time, it will drive the cleaning disc 353 and the nylon brush 354 to clean the surface of the aerator 344 to facilitate better subsequent aeration. The treated water can be discharged through subsequent processes.
