[0002] Silicate cement is a common type of cement, made from silicate cement clinker, gypsum, grinding aids, and reinforcing agents. These raw materials are processed through mixing, grinding, and calcination to form silicate cement products. However, traditional equipment often uses a single rotating blade or stirring rod to mix the raw materials. Although this method is simple, it often requires a long residence time to ensure that the raw materials are fully mixed, resulting in low mixing efficiency.

[0003] For example, the utility model patent (application number: 202221265462.2) discloses a "high-efficiency homogenizing device for silicate cement dry powder," the description of which states that it includes a frame, a body with a top opening fixedly connected to the top of the frame, a stirring assembly for stirring inside the body, and a drive assembly for driving the stirring assembly to rotate on the frame.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A silicate cement component mixing device includes a mixing chamber 1, with a funnel-shaped connecting hopper 2 fixedly connected to the bottom of the mixing chamber 1. A rotating component 4 is provided inside the connecting hopper 2, which is used to fully mix the materials by rotation. A guiding component 3 is provided at the bottom of the connecting hopper 2, which is used to slow down the falling speed of the materials. A diversion component 5 is provided inside the mixing chamber 1, with several rotating parts at the bottom of the diversion component 5. A collecting component 7 is provided at the bottom of the guiding component 3, which is used to guide the mixed materials to the same outlet for outflow. The rotating component 4 includes several upward rotating parts, which are used to drive the raw materials upward by rotation.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, the guiding component 3 includes a protective hopper 31 located below the connecting hopper 2. The protective hopper 31 is funnel-shaped with one end of its larger opening facing downwards. The shape of the protective hopper 31 allows the mixed material to be guided along the inclined surface onto the collecting component 7. Several triangular ribs 32, which are fixedly connected to the connecting hopper 2, are equidistantly fixed on the circumference of the protective hopper 31. The triangular ribs 32 are used to fix the protective hopper 31. The triangular ribs 32 are inclined and their diagonals are located at the top. The material on the protective hopper 31 is separated by the diagonals, thereby slowing down its falling speed and preventing it from falling too fast and causing the material to splash out. At the same time, it prevents the material from directly impacting the triangular ribs 32, which would cause the triangular ribs 32 to wear out too quickly.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the rotating assembly 4 also includes a mounting shaft 41 rotatably connected to the top of the protective bucket 31 and located inside the connecting bucket 2. When the mounting shaft 41 rotates, it drives several arc-shaped plates 42 to rotate around itself. A motor 33 is fixedly installed at the bottom of the protective bucket 31. When the motor 33 is started, it drives the mounting shaft 41 to rotate. The motor 33 is protected below the protective bucket 31. The output end of the motor 33 passes through the protective bucket 31 and is fixedly connected to the mounting shaft 41. Several upper rotating parts are equidistantly arranged on the circumference of the mounting shaft 41.

[0033] Furthermore, such as Figure 2As shown, the upper rotating component includes an arc-shaped plate 42 fixedly connected to the mounting shaft 41. When the mounting shaft 41 rotates, it drives several arc-shaped plates 42 to rotate around the mounting shaft 41. The arc-shaped plates 42 are inclined. When the inclined arc-shaped plates 42 rotate, they guide several raw materials flowing down from between the guide plates 6 upward, so that these upwardly guided raw materials collide with the continuing to fall raw materials for final mixing. When the material above the rotating component 4 reaches a certain amount, the material will fall by gravity and fall through the gap between the rotating component 4 and the connecting hopper 2, thereby flowing into the collecting component 7 through the guide component 3. The top of the arc-shaped plate 42 is provided with an arc-shaped groove, which can better catch the material. At the same time, the shape of the arc-shaped groove makes the path of material movement more complex, thereby further increasing the mixing effect.

[0034] Example 2

[0035] The silicate cement component mixing device provided in Example 1 has been further optimized, specifically, as follows: Figure 3 As shown, the diversion component 5 includes a conical block 51 located inside the mixing chamber 1. The top of the mixing chamber 1 is provided with a feed inlet, through which raw materials are poured into the interior of the mixing chamber 1. The conical block 51 is used to guide the raw materials entering from the middle at the top downward to the periphery of the conical block 51, so that the raw materials can fully contact each other and undergo preliminary mixing. At the same time, it guides the raw materials to the outside of several guide plates 6.

[0036] Furthermore, such as Figure 3 As shown, the diversion component 5 also includes several triangular prisms 52 that are equidistantly fixed to the outside of the conical block 51. The diagonal of the triangular prism 52 is located at the top. When the raw material falls along the circumference of the conical block 51, it is separated by the diagonal of the top of the triangular prism 52. The material is guided by the triangular prism 52 to a narrower opening between adjacent triangular prisms 52, so that the material collides with each other along the way and thus undergoes preliminary mixing. The triangular prism 52 is fixedly connected to the mixing chamber 1.

[0037] Furthermore, such as Figure 4 As shown, several rotating components include several guide plates 6 equidistantly located outside the mounting shaft 41 and fixedly connected to the top of the connecting bucket 2. The guide plates 6 are arc-shaped and have a raised side, making them narrower at both sides and wider in the middle. The raw material enters the spacing between the guide plates 6 through the wider opening, and then enters the narrower interior, causing the raw material to collide together and mix thoroughly. The arc shape changes the path of the raw material into the middle, while extending the path and slowing down its descent speed, so that the raw material can fully collide and mix with each other along the way.

[0038] Example 3

[0039] The silicate cement component mixing devices provided in Examples 1 and 2 have been further optimized, such as... Figure 1 Figure 5 As shown, the collecting component 7 includes an annular guide frame 71 located below the protective hopper 31. Material sliding down the top of the protective hopper 31 is caught by the annular guide frame 71. The front end of the annular guide frame 71 is fixedly connected to a discharge frame 72. Several support columns 73 are fixedly provided at the bottom end of the annular guide frame 71. The support columns 73 are used to support the annular guide frame 71. The discharge frame 72 and the annular guide frame 71 are inclined. The inclined angle causes the material inside the annular guide frame 71 to slide towards the discharge frame 72, thereby allowing the material to slide out through the discharge frame 72.

[0040] The usage process of the silicate cement component mixing device provided by this utility model is as follows:

[0041] When multiple raw materials need to be mixed, the motor 33 is started, and the proportioned raw materials are poured in through the feed port at the top of the mixing chamber 1. After the raw materials enter the interior of the mixing chamber 1, they are guided by the conical block 51 to the surrounding triangular prisms 52. The diagonal of the top of the triangular prism 52 separates the raw materials, allowing them to enter the opening between the adjacent triangular prisms 52 through the guide of the inclined surface. During the process, the raw materials come into contact with each other and collide due to entering the narrow area, thus carrying out preliminary mixing.

[0042] The raw material then falls to the top of the connecting hopper 2 and slides onto several guide plates 6, where it is further mixed. It then enters the central rotating assembly 4, where the rotating arc plate 42 guides the raw material upward. At the same time, the rotating assembly 4 blows air upward, further guiding the raw material upward, causing it to collide with the downward-flowing raw material and promoting cross-mixing. When a large amount of raw material accumulates at the top of the rotating assembly 4, it falls downward by gravity, passing through the gap between the arc plate 42 and the inner wall of the connecting hopper 2. The mixed material is guided by the protective hopper 31 into the annular guide frame 71, and then slides into the discharge frame 72 through the tilt angle of the annular guide frame 71, where it flows out.
