[0002] In the prior art, the flocculation technology is often used to treat sewage. Making the suspended particles in water or liquid gather and become larger, or forming flocs, so as to accelerate the coagulation of particles and achieve the purpose of solid-liquid separation. This phenomenon or operation is called flocculation. Usually, the implementation of flocculation depends on adding appropriate flocculants, whose function is to adsorb the particles and "bridge" between the particles, thus promoting aggregation.

[0003] In the flocculation tank, the sewage is generally stirred by stirring blades, and the stirring effect is poor. It is difficult to quickly mix the sewage and the flocculant, resulting in a long flocculation time and low efficiency. Content of the Utility Model

[0005] To solve the above problems, the technical solution of the utility model is: a novel mixing and flocculation stirring device, including a flocculation tank and a stirring component arranged inside the flocculation tank. The stirring component includes a hexagonal guide cylinder, a base arranged below the guide cylinder, and a stirring shaft arranged inside the guide cylinder. Both the upper and lower ends of the guide cylinder are provided with openings, and six fixing plates are fixedly connected along the diagonal direction at the inner lower part of the guide cylinder. The base is a hexagonal pyramid structure adapted to the guide cylinder, and a plurality of vertical plates are fixedly connected to the base. A plurality of blades are installed at the bottom of the stirring shaft.

[0006] Further, the guide cylinder is installed inside the flocculation tank through a plurality of positioning rods.

[0007] Further, a sleeve sleeved outside the stirring shaft is fixedly connected at the center inside the guide cylinder, and the other end of the fixing plate is fixedly connected to the sleeve.

[0008] Further, a flow guiding port is formed between every two of the fixing plates.

[0009] Further, the blades are located between the guide cylinder and the base.

[0010] Further, there are six vertical plates, which are located on the inclined sides of the hexagonal pyramid.

[0011] Further, a cross plate is arranged at the top of the flocculation tank, and a reduction motor for driving the stirring shaft to rotate is installed on the cross plate.

[0012] Further, the volume of the guide cylinder is 1 / 20 of that of the flocculation tank, and the displacement of the blades is 1 / 2 of that of the guide cylinder.

[0013] The advantages of the present utility model compared with the existing technology are as follows: Through the design of the draft tube and the base, the present utility model can quickly and efficiently circulate the solution inside the flocculation tank and generate flocs. The internal flow field has a higher flow velocity, a larger circulation volume, and richer turbulence, which helps with flocculation mixing and improves the flocculation efficiency.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0019] As Figure 1 and Figure 2 shown, a new type of mixing and flocculation stirring device includes a flocculation tank 1 and a stirring assembly arranged inside the flocculation tank 1. The stirring assembly includes a draft tube 2 with a hexagonal structure, a base 3 arranged below the draft tube 2, and a stirring shaft 4 arranged inside the draft tube 2.

[0020] As Figure 3 shown, the draft tube 2 is installed inside the flocculation tank 1 through a plurality of positioning rods 8. Both the upper and lower ends of the draft tube 2 are provided with openings, and six fixed plates 5 are fixedly connected along the diagonal direction at the inner lower part of the draft tube 2. A sleeve 9 sleeved outside the stirring shaft 4 is fixedly connected at the center inside the draft tube 2, and the other end of the fixed plate 5 is fixedly connected to the sleeve 9. The space between every two fixed plates 5 forms a diversion opening.

[0021] The draft tube 2 is a hexagonal cylinder formed by cutting and welding or bending and welding stainless steel plates. The fixed plates 5 are welded along the diagonal of the hexagon, and the sleeve 9 is welded at the connection of the six fixed plates 5.

[0022] Figure 2As shown, the base 3 is a hexagonal pyramid structure adapted to the draft tube 2, and a plurality of vertical plates 6 are fixedly connected to the base 3. There are six vertical plates 6, and they are located on the hypotenuses of the hexagonal pyramid.

[0023] The base 3 can be made into a hexagonal pyramid structure using cement or stainless steel, and the vertical plates 6 are fixedly installed on the hypotenuses of the hexagonal pyramid, that is, the processing and forming of the base 3 is completed.

[0024] As Figure 1 and Figure 2 As shown, a plurality of blades 7 are installed at the bottom of the stirring shaft 4. A cross plate 10 is provided at the top of the flocculation tank 1, and a reduction motor 11 for driving the rotation of the stirring shaft 4 is installed on the cross plate 10.

[0025] The blade 7 is formed by bending after being cut and trimmed using a laser cutting machine or wire cutting machine from stainless steel.

[0026] In specific use, the reduction motor 11 is a variable frequency reduction motor. The reduction motor 11 drives the blade 7 to rotate clockwise through the stirring shaft 4 at a rotational speed of 60 - 80 rpm, generating an upward flow state. The solution enters the draft tube 2 from six diversion ports and is discharged from the opening at the upper end of the draft tube 2. The volume of the draft tube 2 is designed to be 1 / 20 of the flocculation tank 1, and the displacement of the blade 7 is designed to be 1 / 2 of the draft tube 2. It can quickly and efficiently circulate the solution inside the flocculation tank 1 and generate flocs. A higher internal flow field velocity, a larger circulation volume, and richer turbulence contribute to flocculation mixing. Thus, in the case of a large flocculation tank 1, a small blade agitator can be used, and a low-power reduction gear can be selected to significantly reduce energy consumption.
