Description

Technical Field

[0001] This utility model relates to the field of mixing machine technology, and in particular to a dual-material mixing and feeding device. Background Technology

[0002] A mixing machine is a device used to mix materials. It is usually used in conjunction with a mill and a material conveyor to form a complete material mixing and feeding system, realizing the feeding, mixing and grinding of materials.

[0003] Existing mixers typically have multiple independent hoppers to simultaneously feed various materials, enabling mixing and grinding. However, due to the different types of materials, their particle sizes vary. When the mixer feeds materials of different sizes into the mill, the mill cannot separate the different particle sizes, resulting in the same grinding time for small and large particles. To ensure that all materials reach the standard particle size, the mill's grinding time is determined by the grinding progress of large or difficult-to-grind materials. This leads to some small or easily grindable materials being ground to a particle size far smaller than the standard particle size, resulting in unnecessary grinding and wasted energy. Furthermore, the different particle sizes of different materials after grinding cause uneven mixing and a poor mixing effect.

[0004] Therefore, it is necessary to propose a dual-material mixing and feeding device to ensure that the particle size of different materials after grinding is the same or similar, thereby reducing the energy consumption of the mill and improving the mixing effect of the materials. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing mixing and feeding devices result in different grinding particle sizes of different materials after feeding, leading to high energy consumption of the mill and uneven mixing of materials. A dual-material mixing and feeding device is provided.

[0006] The technical solution of this utility model is:

[0007] A dual-material mixing and feeding device includes a feeding mechanism, a grinding mechanism, and a mixing mechanism. The feeding mechanism includes a frame and a shell. The shell is fixedly connected to the frame. A partition is vertically placed inside the shell, dividing the interior of the shell into two independent material bins. Each material bin has a through hole at its bottom. The bottom of the shell is provided with a sealing plate for sealing the through hole. The sealing plate has an opening that matches the through hole. The sealing plate is rotatably connected to the shell. When the sealing plate rotates, the opening can move to be coaxial with one of the through holes.

[0008] The grinding mechanism is located at the bottom of the sealing plate. A hopper is provided at the feed inlet of the grinding mechanism. The top opening of the hopper faces the sealing plate. The mixing mechanism is connected to the discharge outlet of the grinding mechanism.

[0009] Furthermore, the frame is equipped with a first power unit, and the output end of the first power unit is equipped with a drive gear. The sealing plate is fixedly connected to an external gear ring, and the drive gear meshes with the external gear ring for transmission.

[0010] Furthermore, the top of the shell is provided with a cover plate, which seals the top of the hopper. Each hopper is provided with a stirring blade. Two transmission gears are provided on the outside of the shell. Each transmission gear is equipped with a rotating shaft. Each rotating shaft passes through the cover plate and is fixedly connected to a stirring blade. The rotating shaft is rotatably connected to the cover plate.

[0011] Furthermore, a second power unit is installed on the frame, and the output end of the second power unit is connected to a drive gear, which meshes with two transmission gears simultaneously.

[0012] Furthermore, the cover plate is equipped with at least two material inlets that are connected to the silos, with each of the two silos corresponding to one of the two material inlets.

[0013] This utility model discloses a dual-material mixing and feeding device. Two independent hoppers within the housing can hold two materials of different particle sizes or types. By rotating the sealing plate, the opening is aligned with one of the through holes, allowing normal material feeding. The discharged material enters the grinding mechanism for grinding. The grinding time is set according to the particle size. Once the grinding meets the requirements, the material is discharged into the mixing mechanism for further mixing. After grinding of one material, the sealing plate can continue to rotate, aligning the opening with the other through hole, allowing normal material feeding. The grinding mechanism then grinds the material entering at this time, again setting the grinding time according to the particle size. Once the requirements are met, the material is discharged into the mixer for further mixing. Compared with traditional technologies, this solution achieves separate grinding of materials of different particle sizes, ensuring that after grinding, materials of different sizes have similar or identical particle sizes, saving energy consumption in the grinding machine and improving the mixing effect.

[0017] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0018] Example 1

[0019] like Figure 1 and Figure 2 As shown, this embodiment provides a dual-material mixing and feeding device, including a feeding mechanism 1, a grinding mechanism 2, and a stirring mechanism 3. The feeding mechanism 1 includes a frame 4 and a housing 5. The housing 5 is fixedly connected to the frame 4 with screws. A partition 6 is vertically placed inside the housing 5 and is fixedly connected to the housing 5 with screws. The partition 6 divides the interior of the housing 5 into two independent hoppers 7. Each hopper 7 has a through hole 8 at its bottom. The bottom of the housing 5 is provided with a sealing plate 9 for sealing the through hole 8. The sealing plate 9 has an opening 10 that matches the through hole 8. The sealing plate 9 is rotatably connected to the housing 5. When the sealing plate 9 rotates, the opening 10 can move to be coaxial with one of the through holes 8. The sealing plate 9 is in contact with the bottom surface of the housing 5. The grinding mechanism 2 is located at the bottom of the sealing plate 9. A collecting hopper 11 is provided at the inlet of the grinding mechanism 2. The top opening of the collecting hopper 11 faces the sealing plate 9. The stirring mechanism 3 is connected to the outlet of the grinding mechanism 2.

[0020] Preferably, the frame 4 is equipped with a first power device 12, and the output end of the first power device 12 is equipped with a drive gear 13. The sealing plate 9 is fixedly connected to an external gear ring 14. The drive gear 13 meshes with the external gear ring 14 for transmission. The drive gear 13 is fixedly connected to the first power device 12 by a key. The external gear ring 14 is fixed to the sealing plate 9 by screws. The first power device 12 is a motor. The first power device 12 drives the sealing plate 9 to rotate, so that the opening 10 and the two through holes are coaxially aligned.

[0021] Preferably, the top of the housing 5 is provided with a cover plate 15, which seals the top of the hopper 7. The cover plate 15 is fixedly connected to the housing 5 with screws. Each hopper 7 is provided with a stirring blade 16. Two transmission gears 17 are provided on the outside of the housing 5. Each transmission gear 17 is equipped with a rotating shaft. Each rotating shaft passes through the cover plate 15 and is fixedly connected to a stirring blade 16 with screws. The rotating shaft is rotatably connected to the cover plate 15 through bearings. The rotating shaft is fixedly connected to the transmission gear 17 through a key.

[0022] Preferably, the frame is equipped with a second power unit 18, the output end of which is connected to a drive gear 19. The drive gear 19 meshes with two transmission gears 17 simultaneously. The second power unit 18 is a motor, and the drive gear 19 is fixed to the output shaft of the motor with a key. The second power unit 18 drives the transmission gears 17 to rotate, thereby causing the stirring blades 16 to stir the material in the hopper 7. Since there are two independent hoppers 7 inside the shell 5, each hopper 7 can not only hold the same type of material, but also multiple materials can be classified and placed in the two hoppers 7. Materials with larger particle sizes that are not easy to grind can be placed in one hopper 7, while materials with relatively smaller particle sizes that are easy to grind can be placed in the other hopper 7. In this case, the stirring blades 16 can play a role in stirring and mixing, so that multiple materials in the same hopper 7 are mixed together, assisting the stirring mechanism 3 in mixing the materials and improving the degree of mixing uniformity.

[0023] Preferably, the cover plate 15 is provided with at least two material inlets 20 that communicate with the hopper 7, and the two hoppers 7 correspond one-to-one with the two material inlets 20, so that materials can be conveniently added into the two hoppers 7 through the material inlets 20.

[0024] During operation, the two independent hoppers 7 inside the shell 5 can hold two different particle sizes or different types of materials. By rotating the sealing plate 9, the opening 10 is made coaxial with one of the through holes 8, allowing the material to be discharged normally through the through hole 8. The discharged material enters the grinding mechanism 2 for grinding. The grinding time is set according to the particle size. When the grinding meets the requirements, the material is discharged into the mixing mechanism 3 for mixing. After the grinding of this material is completed, the sealing plate 9 can continue to rotate so that the opening 10 is coaxial with the other through hole 8, allowing the other through hole 8 to discharge normally. The grinding mechanism 2 grinds the material that enters at this time, and the grinding time is set again according to the particle size. When the requirements are met, the material is discharged into the mixer for mixing. Compared with traditional technology, this technical solution realizes the separate grinding of materials with different particle sizes, ensuring that after grinding, materials of different sizes have the same or similar particle size, saving the energy consumption of the grinding machine and improving the mixing effect.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
