[0018] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The staged sedimentation technology is a method for monitoring and controlling the layered settlement of foundation soil at different depths. It sets observation points or instruments at different depths of the foundation to accurately measure the settlement of each layer. When using the staged sedimentation technology to coagulate and settle sewage, high-efficiency integrated coagulation and sedimentation equipment is used. There is usually a stirring step in the high-efficiency integrated coagulation equipment, the purpose of which is to accelerate the mixing of the coagulant aid with the particles in the sewage before sedimentation.

[0020] See also Figure 1-Figure 3 As shown, the present embodiment provides a high-efficiency integrated coagulation and sedimentation device based on the staged sedimentation technology, including a supporting base 1, a mounting bracket 2 and a processing box 3, wherein the upper surface of the supporting base 1 is fixedly connected to the lower surface of the mounting bracket 2, and the mounting bracket 2 is connected to the outer wall of the processing box 3. Considering that the sedimentation is carried out after stirring, the efficiency is low, and during the stirring process, the coagulation product after synthesis is likely to be disrupted and separated again by the stirring paddle 3010, resulting in low working efficiency. Therefore, the details are as follows: an operating chamber is opened inside the processing box 3, and a threaded rod 30 is rotatably connected inside the operating chamber, and a connecting tube 301 and a mounting plate 302 are threadedly matched on the outer wall of the threaded rod 30, wherein: the lower surface of the connecting tube 301 is fixedly connected to the upper surface of the mounting plate 302, and a plurality of water inlet mechanisms 4 are arranged on the surface of the mounting plate 302.

[0021] The improvement of this embodiment is that:

[0022] By rotating the threaded rod 30, the connecting tube 301 drives the mounting plate 302 to rotate and rise and fall at the same time, so that the rotation of the stirring paddle 3010 accelerates the mixing of the coagulant and the particles in the sewage; by arranging the water inlet mechanism 4 on the mounting plate 302, the evenly mixed liquid can only enter from top to bottom through the liquid inlet hole 40, and precipitate under the mounting plate 302, and the evenly mixed liquid below cannot flow to the top through the water inlet mechanism 4, so that while the stirring coagulant accelerates the mixing, it will not affect the flocculation precipitation, and will not disrupt the precipitation after the precipitation is completed, thereby greatly improving the work efficiency.

[0023] Considering that the evenly mixed liquid below the mounting plate 302 may flow into the top of the mounting plate 302, the water inlet mechanism 4 includes a liquid inlet hole 40, the inner wall of the liquid inlet hole 40 is fixedly connected to a connecting plate 401, the lower surface of the connecting plate 401 is fixedly connected to an elastic spring 402, and the bottom end of the elastic spring 402 is fixedly connected to a blocking ball 403. The liquid can only enter from the top of the liquid inlet hole 40 by using the elastic spring 402 to push the blocking ball 403. The liquid below the mounting plate 302 cannot flow from the bottom to the top due to the action of the blocking ball 403.

[0024] In order to accelerate the uniform mixing of the coagulant and the particles in the sewage, a plurality of stirring paddles 3010 are evenly installed in a ring shape on the outer wall of the connecting tube 301, and a sealing ring 3011 is provided on the upper surface of the connecting tube 301. The stirring paddles 3010 are driven to rotate during the rotation of the connecting tube 301 to accelerate the uniform mixing.

[0025] In order to achieve high-concentration recycling of sludge and recycle the excess coagulant, a conduit 31 is installed on the lower surface of the treatment box 3, wherein the other end of the conduit 31 passes through the upper part of the outer wall of the treatment box 3 to the inside of the treatment box 3, and a sludge pump 310 is installed on the side of the axis of the conduit 31. The sludge pump 310 is used to return the settled sludge to the top of the installation plate 302 through the conduit 31 for further recycling.

[0026] Since water heating can significantly improve the removal rate of microplastics and other particles, a cavity 35 is opened between the treatment box 3 and the operating chamber. A heating plate is provided inside the cavity 35. The liquid inside the treatment box 3 is heated by the heating plate, and the particles are more easily precipitated together with the scale, thereby being effectively removed.

[0027] In order to facilitate the rotation of the threaded rod 30, a driving motor 32 is installed at the center of the lower surface of the processing box 3, wherein: the output end of the driving motor 32 is fixedly connected to the bottom end of the threaded rod 30, and the threaded rod 30 can be rotated by starting the driving motor 32 to generate a rotating magnetic field using the energized coil and acting on the rotor to form a magneto-electrodynamic rotating torque.

[0028] Considering that sewage needs to enter the treatment box 3 and the clean water after treatment needs to be discharged, a water inlet cylinder 34 is installed on the upper surface of the treatment box 3, and a water outlet pipe 33 is arranged below the outer wall of the treatment box 3, wherein: a water outlet valve is installed on the outer wall of the water outlet pipe 33, and the liquid enters through the water inlet cylinder 34, and the clean water is discharged through the water outlet pipe 33.

[0029] When the utility model is used, the staff puts sewage and coagulant into the treatment box 3 through the water inlet tube 34 and starts the driving motor 32 at the same time. The energized coil is used to generate a rotating magnetic field and act on the rotor to form a magneto-electric power rotation torque to rotate the threaded rod 30, so that the connecting tube 301 drives the mounting plate 302 to rotate and lift at the same time, so that the rotation of the stirring paddle 3010 accelerates the mixing of the coagulant and the particles in the sewage. At the same time, the heating plate heats the liquid inside the treatment box 3. The evenly mixed liquid can only enter from the top of the liquid inlet hole 40 by using the elastic spring 402 to push the blocking ball 403. The liquid below the mounting plate 302 cannot flow from the bottom to the top due to the action of the blocking ball 403. After that, the water outlet valve can be opened to discharge the clean water on the sediment through the water outlet pipe 33, and the sludge pump 310 can be opened to re-enter the precipitated sludge through the conduit 31 to the top of the mounting plate 302 inside the treatment box 3 for continuous recycling.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
