Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mixing equipment, in particular to a clay mixing cutter head for a fluidized solidified soil mixer. Background Technique
[0002] Fluidized solidified soil, also known as the cement soil slurry solidification method, is a new type of soil improvement technology. Its basic principle is to mix materials such as cement and fly ash with soil or sand to form a fluidized solid body, which is then solidified into a soil material with engineering usability, and is widely used in projects such as mountains, slopes, and roads.
[0003] During the mixing process of fluidized solidified soil, mixing tanks of different specifications often have mixing positions at different heights. Therefore, it is generally necessary to prepare a variety of mixing cutter heads with different mixing heights, resulting in high stocking costs and large space occupation. In addition, as the amount of soil added increases, the viscosity of the mixing slurry at the lower part of the mixing tank will gradually increase, which will greatly affect the operation of the lower and bottom mixing blades, and thus easily affect the operation efficiency and mixing quality. Summary of the Utility Model
[0004] An embodiment of the present application provides a clay mixing cutter head for a fluidized solidified soil mixer, which can change the height position of the main body section in the mixing tank by selecting and connecting displacement connection sections of different lengths, realizing the application of the mixing cutter head in mixing tanks of different specifications. In addition, it can also improve the mixing efficiency and mixing quality of the lower viscous slurry through the auxiliary mixing blades connected at the bottom layer mixing blades.
[0005] An embodiment of the present application provides a clay mixing cutter head for a fluidized solidified soil mixer, including a main body section arranged in a suspended state in the mixing tank. One end of the main body section close to the tank mouth of the mixing tank is coaxially connected with a displacement connection section. The main body section is axially provided with mixing blades in sequence, including a top layer mixing blade, a middle layer mixing blade, and a bottom layer mixing blade. The top layer mixing blade is close to the displacement connection section. The plane of the bottom layer mixing blade extends along the radial plane of the main body section and is connected with an auxiliary mixing blade at the outer end. The planes of the top layer mixing blade, the middle layer mixing blade, and the auxiliary mixing blade extend obliquely in the same direction relative to the radial plane of the main body section, where the radial plane of the main body section is a plane perpendicular to the axial direction of the main body section.
[0006] In a possible implementation manner, the main body section is connected to the displacement connection section through a flange.
[0007] In a possible implementation, both the top stirring blades and the bottom stirring blades have one layer, the middle layer stirring blades have one layer or multiple layers, and when the middle layer stirring blades have multiple layers, the multiple middle layer stirring blades are evenly distributed between the top stirring blades and the bottom stirring blades.
[0008] In a possible implementation, the auxiliary stirring blades extend along the axial direction of the main body section.
[0009] In a possible implementation, the auxiliary stirring blades extend obliquely with respect to the axial direction of the main body section. One end of the auxiliary stirring blade close to the displacement connection section is relatively far from the main body section, and the inclination angle of the auxiliary stirring blade is adapted to the inclination angle of the conical bottom of the stirring tank body.
[0010] In a possible implementation, the maximum distance between the stirring blades sequentially distributed in the axial direction of the main body section and the main body section gradually decreases from one end close to the displacement connection section to the opposite end.
[0011] Advantageous effects: Compared with the prior art, the clay stirring cutter head of the fluidized soil solidifying mixer provided in this application is connected with a displacement connection section at the top of the main body section provided with stirring blades. Different lengths of the displacement connection section can be flexibly selected to change the stirring position of the main body section in the stirring tank body, so that the stirring cutter head can be applied in stirring tanks of different specifications, and the application range is wide. In addition, auxiliary stirring blades are connected to the outer ends of the bottom stirring blades. At the same time, the surfaces of the top stirring blades, the middle layer stirring blades and the auxiliary stirring blades all extend obliquely in the same direction with respect to the radial plane of the main body section, which can effectively improve the stirring efficiency and quality of the lower part and the bottom of the stirring tank body, and the stirring effect is better.
[0012] Among them, when the auxiliary stirring blades extend along the axial direction of the main body section, the stirring cutter head can be applied to the stirring of a cylindrical stirring tank body. When the auxiliary stirring blades extend obliquely with respect to the axial direction of the main body section, the stirring cutter head can be applied to the stirring of a stirring tank body with a conical bottom.
[0013] These and other objects, features and advantages of the present utility model are fully embodied through the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

The basic principles defined in the following description can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present invention.
[0018] Those skilled in the art should understand that in the disclosure of the specification, the orientation or positional relationship indicated by terms such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.
[0019] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "one" should not be construed as a limitation on the quantity.
[0020] Reference Figures 1 to 3 , an embodiment of the present application provides a clay mixing cutter head for a fluidized soil mixer, including a main body section 20 arranged in a suspended state in the mixing tank 10. One end of the main body section 20 close to the tank opening 101 of the mixing tank 10 is coaxially connected with a displacement connection section 30. In this way, by flexibly selecting displacement connection sections 30 of different lengths for connection, the mixing position of the main body section 20 in the mixing tank 10 can be changed, so that the mixing cutter head provided by the present application can be applicable to the mixing of mixing tanks 10 of various specifications, with a wide range of applications. At the same time, excessive stocking can be avoided, and the stocking cost can be reduced. Among them, in the connection method between the main body section 20 and the displacement connection section 30, connection through a flange 31 can be selected. As a common auxiliary accessory, the flange is easier to purchase or process and manufacture, making the mixing cutter head provided by the present application easier to be formed and facilitating later maintenance.
[0021] The main body section 20 is axially provided with stirring blades 21 in sequence, including a top-layer stirring blade 211, a middle-layer stirring blade 212, and a bottom-layer stirring blade 213. Among them, the top-layer stirring blade 211 is close to the displacement connection section 30. Among them, the surface of the bottom-layer stirring blade 213 extends along the radial plane of the main body section 20. That is to say, when the main body section 20 extends vertically, the bottom-layer stirring blade 213 extends horizontally, and the surface of the bottom-layer stirring blade 213 also remains extended in the horizontal direction. In addition, an auxiliary stirring blade 214 is connected to the outer end of the bottom-layer stirring blade 213. At the same time, the surfaces of the top-layer stirring blade 211, the middle-layer stirring blade 212, and the auxiliary stirring blade 214 extend obliquely in the same direction relative to the radial plane of the main body section 20. The radial plane of the main body section 20 is a plane perpendicular to the axis of the main body section 20. Thus, the slurry stirring efficiency and stirring quality at the lower part and the bottom of the stirring tank body 10 can be effectively improved by the auxiliary stirring blade 214 additionally connected to the outer end of the bottom-layer stirring blade 213, and the stirring effect is better. Among them, the surfaces of the top-layer stirring blade 211, the middle stirring blade 212, and the auxiliary stirring blade 214 can be integrally planar inclined, and the inclination angle is selected to be between 40° and 75°. In addition, it can also be rotationally curved inclined. In addition, the surface refers to the surface with a larger area of the stirring blade.
[0022] In one embodiment, both the top-layer stirring blade 211 and the bottom-layer stirring blade 213 have one layer. The middle-layer stirring blade 212 has one layer or multiple layers. At the same time, when the middle-layer stirring blade 212 has multiple layers, the multiple middle-layer stirring blades 212 are evenly distributed between the top-layer stirring blade 211 and the bottom-layer stirring blade 213.
[0023] In one embodiment, the auxiliary stirring blade 214 extends along the axis of the main body section 20. This is applicable to the stirring of the cylindrical stirring tank body 10. The auxiliary stirring blade 214 that extends obliquely stirs sufficiently at the lower part and the bottom of the stirring tank body 10.
[0024] In another embodiment, the auxiliary stirring blade 214 extends obliquely relative to the axis of the main body section 20. At the same time, one end of the auxiliary stirring blade 214 close to the displacement connection section 30 is relatively far from the main body section 20, and the inclination angle of the auxiliary stirring blade 214 is adapted to the inclination angle of the conical bottom on the stirring tank body 10, so as to be applicable to the stirring of the stirring tank body 10 with a conical bottom.
[0025] In one embodiment, the maximum distance between the stirring blades 21 and the main body section 20, which are axially distributed in sequence on the main body section 20, gradually decreases from one end close to the displacement connection section 30 to the opposite end. That is to say, among all the stirring blades 21 perpendicular to the main body section 20, including all the top-layer stirring blades 211, middle-layer stirring blades 212, and bottom-layer stirring blades 213, the lengths of the stirring blades 21 gradually decrease, and the stirring distances also gradually decrease. As a result, the stirring cutter head can generate a better flow pattern during the stirring process, which helps the materials to be mixed more evenly and can improve the stirring efficiency to a certain extent. Generally, for a stirring tank body 10 with a conical bottom, the length of the stirring blades 21 at the conical part is significantly smaller than that of the upper cylindrical part to adapt to the gradually decreasing inner diameter. For a conventional cylindrical stirring tank body 10, the lengths of all the stirring blades 21 can decrease uniformly, and the length difference is not very obvious. In addition, this design with gradually decreasing lengths of the stirring blades 21 can also reduce the excessive shearing of the slurry, is particularly suitable for processing materials with high viscosity or containing solid particles, and helps to maintain the integrity of the materials.

The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments.
