Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a mixing blade with a sky knife. Background Art

[0002] Fluid solidified soil is formed by mixing materials such as cement and fly ash with soil or sand to form a fluid-solid body. Therefore, in the mixing and forming process of fluid solidified soil, a situation with relatively high viscosity is often faced.

[0003] During the operation process, the staff found that during the mixing process, as the viscosity of the soil material increases, in some cases, although the soil material is still rotating continuously, it does not continue to fall, but forms a layer of isolation skin or a cap at the bottom of the soil material close to the mixing blade, and it is necessary for the staff to use tools for intervention after stopping the machine to enable the mixing work to continue, thus there is a problem of low mixing efficiency. Summary of the Utility Model

[0004] An embodiment of the present application provides a mixing blade with a sky knife, which can automatically intervene in the formation of the isolation skin or cap at the bottom of the soil material, thereby ensuring the mixing efficiency.

[0005] An embodiment of the present application provides a mixing blade with a sky knife, including a main body section arranged in a suspended state in the mixing tank body. The main body section is vertically provided with a top-layer mixing blade, a middle-layer mixing blade and a bottom-layer mixing blade in sequence along the axial direction. The top-layer mixing blade is close to the tank opening of the mixing tank body, and a sky knife blade is connected to one end of the top-layer mixing blade close to the tank opening. The sky knife blade extends along the axial direction of the main body section, and a mixing fork is provided at one end of the sky knife blade close to the tank opening.

[0006] In a possible implementation manner, the top-layer mixing blade has one layer, including a plurality of first blades evenly distributed along the circumferential direction of the main body section, and 1 to 3 sky knife blades are connected to each first blade.

[0007] In a possible implementation manner, the sky knife blades are distributed in an axial dislocation along the main body section.

[0008] In a possible implementation manner, the top-layer mixing blade has two layers, respectively including a plurality of second blades evenly distributed along the circumferential direction of the main body section and located in the same layer and a plurality of third blades located in another layer. The second blades are closer to the tank opening than the third blades, and 1 to 3 sky knife blades are connected to both the second blades and the third blades.

[0009] In a possible implementation, all the Tiandao blades connected to the second blade have the same length, and all the Tiandao blades connected to the third blade have the same length. The Tiandao blades connected to the second blade are defined as the second Tiandao blades, and the Tiandao blades connected to the third blade are defined as the third Tiandao blades. The length of the third Tiandao blades is greater than that of the second Tiandao blades, and the outer ends of the third Tiandao blades are closer to the intermediate layer stirring blade relative to the outer ends of the second Tiandao blades.

[0010] In a possible implementation, the surface of the bottom layer stirring blade extends along the radial plane of the main body section and is connected with auxiliary stirring blades at the outer ends. The surfaces of the top layer stirring blade, the intermediate layer stirring blade and the auxiliary stirring blades 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.

[0011] In a possible implementation, one end of the main body section close to the tank mouth is coaxially connected with a displacement connection section through a flange.

[0012] In a possible implementation, the stirring fork is one or more U-shaped openings.

[0013] Advantageous effects: Compared with the prior art, the stirring blade with Tiandao provided by the present application can avoid the formation of the isolation skin or cap at the bottom of the soil material during the process of stirring the fluidized soil by arranging Tiandao blades at one end of the top layer stirring blade close to the tank mouth, and a stirring fork is also arranged at one end of the Tiandao blade close to the tank mouth, so as to play an automatic intervention role with the continuous rotation of the main body section, thereby effectively ensuring the stirring efficiency;

[0014] Among multiple Tiandao blades in the same layer or multiple Tiandao blades in different layers, the lengths of the Tiandao blades are not equal, that is, they are axially staggered and distributed on the main body section, which can break the circular flow during the stirring process, reduce eddy currents and dead angles, and thus can better play an intervention role;

[0015] An auxiliary stirring blade is also connected to the outer end of the bottom layer stirring blade, so as to effectively improve the stirring efficiency and stirring quality of the lower part and the bottom of the stirring tank, and the stirring effect is better;

[0016] One end of the main body section close to the tank mouth is also coaxially connected with a displacement connection section, so that the stirring position of the main body section in the stirring tank can be changed by flexibly selecting displacement connection sections with different lengths, making the use of this stirring blade more convenient and the applicable range wider.

[0017] These and other purposes, features and advantages of the present utility model are fully embodied by the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and other obvious variations can be thought of by those skilled in the art. 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 depart from the spirit and scope of the present invention.

[0022] 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.

[0023] It can be understood that the term "a" 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 "a" should not be construed as limiting the quantity.

[0024] Reference Figures 1 to 3, an embodiment of the present application provides a stirring blade with a sky knife, including a main body section 10 arranged in a suspended state inside the stirring tank. The main body section 10 is vertically provided with a top-layer stirring blade 11, a middle-layer stirring blade 12, and a bottom-layer stirring blade 13 in sequence along the axial direction, wherein the top-layer stirring blade 11 is close to the tank mouth of the stirring tank, and at the same time, a sky knife blade 14 is connected to one end of the top-layer stirring blade 11 close to the tank mouth. The sky knife blade 14 extends along the axial direction of the main body section 10, and a stirring fork 101 is provided at one end of the sky knife blade 14 close to the tank mouth. In this way, during the process of stirring the fluidized soil, the formation of the bottom isolation skin or cap of the soil material can be automatically intervened by the sky knife blade 14 provided with the stirring fork 101, so as to avoid manual intervention during shutdown, and thus the stirring efficiency can be effectively ensured. The stirring fork 101 can be one or more U-shaped openings.

[0025] In one embodiment, the top-layer stirring blade 11 has one layer, including a plurality of first blades 111 evenly distributed along the circumferential direction of the main body section 10. At the same time, 1 to 3 sky knife blades 14 are connected to each first blade 111. In this way, the reliability of intervening in the formation of the isolation skin or cap can be ensured by the sky knife blades 14 distributed at multiple different positions, and the intervention effect is better.

[0026] Furthermore, the sky knife blades 14 are distributed in an axial dislocation along the main body section 10. That is to say, whether 1 sky knife blade 14 is connected to the first blade 111 or multiple sky knife blades 14 are connected, overall, the sky knife blades 14 in this layer of the top-layer stirring blade 11 are distributed in a dislocation in the height direction. In this way, on the basis of automatically intervening in the formation of the isolation skin or cap, the cyclic flow during the stirring process can also be broken by the designed structure of the dislocation distribution, reducing eddy currents and dead corners, so as to better play the intervention role.

[0027] In another embodiment, in combination with Figure 2 , the top-layer stirring blade 11 has two layers, respectively including a plurality of second blades 112 evenly distributed along the circumferential direction of the main body section 10 and located in the same layer and a plurality of third blades 113 located in another layer. The second blades 112 are closer to the tank mouth than the third blades 113, that is, relatively farther away from the middle-layer stirring blade 12, and 1 to 3 sky knife blades 14 are connected to both the second blades 112 and the third blades 113. In this way, the reliability of intervening in the formation of the isolation skin or cap can be ensured by the sky knife blades 14 distributed at multiple different positions.

[0028] Further, all the saber blades 14 connected to the second blade 112 have the same length. At the same time, all the saber blades 14 connected to the third blade 113 have the same length. In addition, the saber blades 14 connected to the second blade 112 are defined as the second saber blades, and the saber blades 14 connected to the third blade 113 are defined as the third saber blades. The length of the third saber blades is greater than that of the second saber blades, and the outer ends of the third saber blades are closer to the intermediate layer stirring blade 12 relative to the outer ends of the second saber blades. In this way, a staggered distributed structure can be formed by the cooperation of the upper and lower layers of saber blades 14, which can also achieve the effects of breaking the circulating flow during stirring and reducing eddies and dead angles. In addition, since the lengths of the second saber blades are equal and the lengths of the third saber blades are also equal, once a certain saber blade 14 has a problem, the same replacement can be quickly found and installed or welded on, which is convenient for maintenance.

[0029] In one embodiment, the surface of the bottom layer stirring blade 13 extends along the radial plane of the main body section 10, and an auxiliary stirring blade 131 is connected to the outer end. At the same time, the surfaces of the top layer stirring blade 11, the intermediate layer stirring blade 12, and the auxiliary stirring blade 131 extend obliquely in the same direction relative to the radial plane of the main body section 10, where the radial plane of the main body section 10 is a plane perpendicular to the axial direction of the main body section 10. In this way, the stirring efficiency and quality of the lower part and the bottom of the stirring tank can be effectively improved (i.e., enhanced) by the auxiliary stirring blade 131, and the stirring effect is better.

[0030] In one embodiment, the main body section 10 is axially connected with a displacement connection section 20 through a flange 21 at one end close to the tank mouth. In this way, the stirring position of the main body section 10 in the stirring tank can be changed by replacing the displacement connection sections 20 with different lengths, so that the stirring knife provided by the present application is suitable for the stirring operations of stirring tanks of various specifications, with a wide range of applications. At the same time, as a common auxiliary fitting, the flange 21 is convenient to purchase or process and manufacture.

[0031] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. 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. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
