Description

Technical Field

[0002] The accelerated flocculation devices used in sewage treatment are usually designed to improve the flocculation efficiency and sedimentation rate of suspended solid particles in sewage. These devices use physical and chemical methods to cause the tiny particles in sewage to aggregate into larger flocs, which are then easily separated to achieve the purpose of solid-liquid separation and water purification. Magnetic flocculation sewage treatment devices are one of the common treatment equipment.

After the sewage is mixed with the flocculant, magnetic flocs are quickly formed under the action of the magnetic field and quickly settle. Some devices require operators to manually add magnetic powder when treating sewage. Manual addition of magnetic powder not only increases the labor intensity of operators, but also in the continuous operation of sewage treatment process, frequent manual addition may lead to low work efficiency and cannot guarantee the continuity and stability of the treatment process.

[0023] The operator can inject the sewage to be treated into the flocculation barrel 1 along the water inlet pipe 2 to accelerate the flocculation. The water outlet pipe 3 at the bottom can effectively collect the clarified upper water to ensure that the suspended matter can be fully precipitated and remain in the barrel, thereby achieving the purpose of solid-liquid separation. The set water inlet pipe 2 can effectively prevent external debris, dust, rainwater, etc. from falling into the flocculation barrel 1, keep the treatment environment clean, and avoid interference from foreign substances or reduce the treatment effect.

[0024] Furthermore, the stirring mechanism 6 includes a sleeve 601, and the left and right sides of the top of the sleeve 601 are fixedly connected with inclined powder outlet pipes 602, the top of the sleeve 601 extends to the top of the barrel cover 4 and is rotatably connected thereto, the top of the sleeve 601 is fixedly connected with a first gear 604, the top of the sleeve 601 is fixedly connected with a powder adding pipe 607, the top of the powder adding pipe 607 extends to the top of the barrel cover 4 and is rotatably connected to a feeding box 9.

[0025] When it is necessary to perform magnetic flocculation treatment on the sewage, the operator quantitatively puts the magnetic powder stored in the feeding box 9 into the powder adding tube 607, and starts the second motor 608 at the same time. The second motor 608 drives the spiral feeding paddle 609 to rotate inside the sleeve 601. After the magnetic powder falls into the sleeve 601 along the powder adding tube 607, it is transported by the spiral feeding paddle 609 and sprinkled into the sewage along the powder outlet pipe 602. At the same time, the first motor 606 is started, and the first motor 606 drives the second gear 605 to rotate. The second gear 605 thereby drives the first gear 604 meshing therewith to rotate.

When the sleeve 601 rotates, it drives The dynamic stirring rod 603 fully mixes the magnetic powder and sewage, and the stirring mechanism 6 can ensure that the sewage, magnetic powder and flocculant are fully and evenly mixed, so that the magnetic powder can be effectively adsorbed on the pollutants to form magnetic flocs, and the magnetic powder can be automatically added during the sewage treatment process. The dosage of magnetic powder can be dynamically adjusted according to the actual pollution degree of the sewage and the treatment requirements, ensuring that the ideal flocculation effect can be achieved under any circumstances, while avoiding waste of resources caused by excessive addition or incomplete treatment caused by insufficient addition.

The sewage discharge pipe 7 is designed at the bottom of the flocculation barrel 1 to facilitate the timely and effective discharge of these sediments from the equipment, and to keep the internal space for new sewage treatment cycles. The function of the support legs 8 is to stabilize the entire flocculation barrel 1 so that it can be safely placed on the ground and ensure the stability of the equipment during operation.

It provides a human-machine interaction interface for setting, monitoring and controlling the equipment operation parameters. The operator can set the stirring speed, magnetic powder dosage, working mode such as automatic / manual and other key process parameters through the control panel 10. The rotation of the stirring rod 603 can break the laminar flow state inside the sewage, accelerate the collision probability between suspended particles, prompt the pollutant particles to quickly form a larger floc structure, and adsorb magnetic powder to improve the magnetic flocculation effect.

[0032] Furthermore, a spiral feeding paddle 609 is rotatably connected inside the sleeve 601 , and the top of the spiral feeding paddle 609 is fixedly connected to the output end of the second motor 608 , and the second motor 608 is fixedly installed at the top center of the first gear 604 .

[0034] The powder adding tube 607 connected to the feeding box 9 can realize the automatic quantitative feeding of magnetic powder. Through the instructions of the control system, the magnetic powder can be added to the sewage evenly and continuously from the box 901 according to the preset ratio and rate, without the need for frequent manual addition, thereby improving the degree of automation and work efficiency of the treatment process.
