[0027] The following is combined with Figures 1-4 This invention describes a mixing and homogenizing apparatus for preparing wear-resistant materials.
[0028] In one embodiment, a mixing and homogenizing device for preparing wear-resistant materials includes a housing 100 and a stirring rack 200 installed inside it; it also includes four mixing mechanisms 300. The mixing mechanisms 300 are located inside the housing 100 and are used to drive the material to tumble up and down while changing the mixing area in real time, thereby improving the mixing effect and efficiency; wherein, the mixing mechanism 300 includes blades 310, and arc-shaped grooves 311 are provided on both sides of the blades 310. The top view cross section of the blades 310 is I-shaped. A set of turbulence channels 312 are provided on both sides of the blades 310. The set of turbulence channels 312 are arranged in a fan shape and communicate with the arc-shaped grooves 311.
[0029] like Figure 2 and Figure 3 As shown, a rotating shaft 313 is installed on one side of the blade 310. One end of the rotating shaft 313 passes through the stirring frame 200 and is equipped with a first conical tooth 314. A second conical tooth 315 meshes between two adjacent first conical teeth 314.
[0030] In this embodiment, after the material is introduced into the box 100, the rotating stirring rack 200 will drive the blades 310 to revolve, thereby changing the mixing range in real time, ensuring the mixing effect and reducing mixing dead zones. At the same time, the first conical tooth 314 will move along the axis of the second conical tooth 315, thereby cooperating with the rotating shaft 313 to make the blades 310 rotate. During the movement of the blades 310, the arc-shaped groove 311 can assist the material to turn over and increase the material carrying capacity. Its own I-shaped setting can push the material to move during both rotation and revolution, achieving the mixing effect. Combined with the fan-shaped turbulence channel 312, the material can be driven during the movement and the material can be discharged along a specific arc in the turbulence channel 312. After colliding with other materials in the box 100, turbulence is generated, improving the mixing effect.
[0031] It should be noted that when the blade 310 is in a horizontal state, the turbulence channel 312 cannot be activated to produce a turbulence effect, and it does not affect the mixing operation. When the blade 310 is in a vertical state or close to a vertical state, the material can be introduced into the turbulence channel 312 along the arc-shaped channel 311, and then discharged outward in a fan shape.
[0032] The bottom of the box 100 is equipped with a discharge pipe with a valve, and an L-shaped scraper can be installed on the mixing rack 200 to assist in scraping the material on the inner wall of the box 100. The specific size of the L-shaped scraper can be selected accordingly without affecting the movement of the blade 310.
[0033] like Figure 2 and Figure 3 As shown, a column is fixedly installed inside the housing 100, and the second conical tooth 315 is fixedly sleeved on the outside of the column.
[0034] A column is used to support the second bevel tooth 315 to ensure the stability of the second bevel tooth 315 when it meshes with the first bevel tooth 314.
[0035] like Figure 2 and Figure 3 As shown, a sleeve 316 is fitted on the outside of the column and rotatably connected to the inside of the housing 100. One end of the rotating shaft 313 passes through and is rotatably connected to the inside of the sleeve 316.
[0036] During the rotation of the mixing rack 200, the rotating shaft 313 and the sleeve 316 will rotate accordingly, so that the blades 310 can complete the revolution while rotating on their own axis, thereby improving the mixing effect.
[0037] like Figure 1 and Figure 2 As shown, a grinding box 110 connected to the top of the box 100 is installed therein, and grinding balls 111 are arranged inside the grinding box 110; a drive motor is installed on the top of the grinding box 110, and the output shaft of the drive motor is connected to the grinding balls 111 through a coupling; a stirring rack 200 is installed on the outside of the grinding balls 111.
[0038] The grinding balls 111 are driven by a drive motor. The grinding balls 111 and the inner wall of the grinding box 110 are used to crush the material and achieve a homogenization effect. During the operation of the grinding balls 111, the stirring rack 200 is driven to complete the mixing process in the box 100.
[0039] It should be noted that the grinding box 110 is provided with a feed port, the grinding box 110 and the housing 100 are detachable, and the grinding balls 111 are detachable. Users can pre-install grinding balls 111 of the corresponding size according to their needs.
[0040] like Figure 2 and Figure 3 As shown, the connection between the sleeve 316 and the rotating shaft 313 is treated with a rotary seal.
[0041] This reduces the occurrence of accidental material entering the sleeve 316 during the material mixing process, and provides protection for the first bevel tooth 314 and the second bevel tooth 315.
[0042] Working principle: The material is introduced into the feed inlet, and the grinding balls 111 homogenize the material. Then, the mixing frame 200 drives the blades 310 to revolve for mixing. During the revolve, the first conical tooth 314 and the second conical tooth 315 mesh, and the rotating shaft 313 causes the blades 310 to rotate. Thus, the position of the blades 310 changes continuously during the mixing process. During the rotation of the blades 310, the arc-shaped groove 311 receives the material and assists in the material turning. The turbulence trough 312 discharges the material in a fan shape, forming a multi-point turbulence, which improves the mixing effect and efficiency. After the mixing operation is completed, the material is discharged along the discharge pipe.
[0043] It should be noted that the drive motors mentioned above are devices with relatively mature existing technology. The specific model can be selected according to actual needs. The drive motor can be powered by an internal power supply or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.
[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
