Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing equipment, specifically a magnetic coagulation mixing device. Background Technology
[0002] Magnetic coagulation sedimentation technology involves simultaneously adding magnetic powder to the ordinary coagulation sedimentation process, allowing it to flocculate and combine with pollutants to enhance the coagulation and flocculation effect. Since the specific gravity of magnetic powder is 5 times that of water, the specific gravity of the flocs combined with the magnetic powder increases rapidly, resulting in denser and more compact flocs, thereby achieving the purpose of high-speed sedimentation.
[0003] A search revealed that utility model patent application number 2023217653527 discloses a special agitator for magnetic coagulation equipment, comprising a frame, a reaction chamber fixedly connected to the left side of the frame, multiple partitions fixedly connected to the inside of the reaction chamber, a fixed plate fixedly connected to the top of the reaction chamber, multiple stirring shafts uniformly rotatably connected inside the fixed plate, and multiple first drive motors uniformly fixedly connected to the top of the fixed plate. The drive ends of the first drive motors are respectively fixedly connected to the top of the stirring shafts, and multiple stirring rods are fixedly connected to the outside of each stirring shaft. This agitator accelerates the reaction rate of the equipment, improves the purification efficiency of the equipment, can treat larger volumes of wastewater with better results, avoids sludge generated by reaction sedimentation inside the device from affecting subsequent purification, and can also save operating costs through recycling.
[0004] However, in practical applications, the reagent is added from the top of the reaction tank, resulting in a short reaction time between the reagent and the wastewater. Furthermore, the reaction speed can only be increased to a limited extent by stirring with a stirring rod alone, which requires improvement. Utility Model Content

[0006] To solve the above problems, the technical solution of this utility model is as follows: a magnetic coagulation mixing device, including a mixing tank, with a water inlet pipe at the lower part of one end of the mixing tank and a water outlet pipe at the upper part of the other end. The mixing tank is provided with two staggered vertical partitions, which divide the mixing tank into three interconnected mixing chambers T1-T3. A drug delivery pipe is installed on the water inlet pipe. A drug delivery pipe is installed through the lower side of the T3 mixing chamber. An air guide pipe is provided on the lower side of the T1 mixing chamber. Multiple branch pipes extending to the lower part of the T1 mixing chamber are fixed to the side of the air guide pipe. Multiple aeration discs are installed on the branch pipes. A mixing component is installed in each of the T1-T3 mixing chambers.
[0007] Furthermore, both the first and second administration tubes are equipped with one-way valves.
[0008] Furthermore, the T3 agitator is equipped with a drain pipe at the lower part of one end of the water outlet pipe, and a valve is installed on the drain pipe.
[0009] Furthermore, the stirring assembly includes a horizontal plate installed on the top of the mixing tank, a positioning seat fixed to the bottom of the horizontal plate, a stirring shaft rotatably mounted through the positioning seat, a paddle installed at the lower part of the stirring shaft, and a motor for driving the stirring shaft to rotate installed at the top of the horizontal plate.
[0010] Furthermore, the impeller in the T1 mixing chamber includes two arc-shaped mixing blades symmetrically installed in the middle of the mixing shaft and a circular plate installed at the bottom of the mixing shaft. Multiple arc-shaped blades are fixed to the edge of the circular plate.
[0011] Furthermore, the impeller in the T2 mixing chamber includes three sets of mixing blades mounted on the side of the mixing shaft, with each set of mixing blades consisting of three blades.
[0012] Furthermore, the impeller in the T3 mixing chamber includes a spiral-type mixing blade three installed in the middle of the mixing shaft and a circular plate two installed at the bottom of the mixing shaft, with multiple arc-shaped blades two fixed to the edge of the circular plate two.
[0013] The advantages of this invention compared to existing technologies are as follows: the circular plate of this invention drives the blades to rotate, generating high turbulence, which can accelerate the mixing of the agent and the sewage. Aeration can improve the reaction speed between coagulation and sewage, save coagulation time, improve coagulation effect, and enhance the practicality of the equipment. Attached Figure Description

[0022] Mixing chambers T1-T3 are equipped with mixing components. Each mixing component includes a horizontal plate 11 mounted on top of mixing chamber 1. A positioning seat 12 is fixed to the bottom of the horizontal plate 11. A mixing shaft 13 is mounted through and rotatably on the positioning seat 12. A paddle is mounted on the lower part of the mixing shaft 13. A motor 14 for driving the rotation of the mixing shaft 13 is mounted on the top of the horizontal plate 11. The paddle in mixing chamber T1 includes two arc-shaped mixing blades 15 symmetrically mounted in the middle of the mixing shaft 13 and a circular plate 16 mounted at the bottom of the mixing shaft 13.
