Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, specifically a material mixer. Background Technology

[0002] Material mixing is a core step in many industrial production processes, especially in chemical, food, pharmaceutical, building materials, and metallurgical industries, where the mixing effect directly affects product quality and production efficiency. Traditional material mixers generally consist of a stirring paddle, a tank, valves, and material inlets and outlets. In practical applications, they have several drawbacks: because materials need to be fed into the tank for mixing and then discharged, the tank is large, requiring significant driving force and occupying considerable space, resulting in bulky equipment that affects its layout and installation in the production line. Furthermore, maintenance and repair are relatively complex, easily disrupting production continuity, and the equipment has poor wear resistance, leading to severe tank wear and a short lifespan over prolonged use. To address these problems, a new material mixer is proposed to solve these issues. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a material mixer that achieves mixing of materials during the falling process, eliminating the need for material storage, and is small in size with a small mixing disc and low driving force. Moreover, the mixing disc is uniformly equipped with material-pulling blades, and its structure and arrangement can effectively promote the circulation and uniform distribution of materials, thus effectively solving the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A material mixer includes a feeding hopper, a shell, and a mixing rotating disc. The lower end of the feeding hopper corresponds to the central feeding port at the upper end of the shell. The mixing rotating disc is disposed inside the shell. The upper surface of the mixing rotating disc is uniformly provided with material-pulling blades along the circumferential direction, and the mixing rotating disc corresponds to the central feeding port at the upper end of the shell.

[0007] Furthermore, the lower shell is designed with a conical structure, and a discharge port is provided at the lower end of the lower shell.

[0008] Furthermore, fixing plates are provided on both sides of the upper end of the feed hopper, and through holes for fixing are provided on both sides of the fixing plates.

[0018] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a material mixer, including components such as a feeding hopper 1, a shell, and a mixing rotating disk 5; the lower end of the feeding hopper 1 corresponds to the central feeding port at the upper end of the shell, and the lower end of the feeding hopper 1 and the shell can also be fixed by screws to form a channel for the material to enter the shell; the mixing rotating disk 5 is set inside the shell, and its upper surface is uniformly provided with material-distributing blades 6 along the circumferential direction; these blades 6 can effectively disperse and stir the material along the surface of the mixing rotating disk 5, and transfer it downward to the discharge port 14.

[0020] The shell has multiple fixing holes 7 on its circumferential surface, and the inner liner 2 is connected to these fixing holes 7 by screws. The function of the inner liner is to protect the inside of the shell and prevent the shell from being damaged or corroded due to material friction or chemical reaction. The material of the inner liner can be selected according to the actual application, such as stainless steel or polyurethane, which has wear-resistant and corrosion-resistant properties.

[0021] The shell consists of a lower shell 9 and an upper shell 8; the two are connected by a flange to ensure the overall robustness and stability of the shell; the lower shell 9 is designed with a conical structure and has a discharge port 14 at the lower end so that the material can be discharged smoothly after mixing; the conical design helps the material to flow in a concentrated manner and avoids accumulation or blockage during the mixing process.

[0022] The support frame 3 is located inside the lower housing 9. The function of the support frame is to support the fixed position of the entire drive system and ensure the stable operation of the drive components. The drive components are installed on the support frame 3, which drive the mixing rotary disk 5 to rotate, thereby realizing the mixing of materials.

[0023] The drive assembly includes a drive motor 4, which is fixed on the support frame 3; the output shaft of the drive motor 4 is directly connected to the mixing rotary disk 5, and the rotation of the motor directly drives the mixing rotary disk 5 to rotate through the rotation of the shaft; this solution has a simple structure, high transmission efficiency, and is suitable for material mixing processes with high requirements.

[0024] In another embodiment, the drive assembly includes a drive motor 4, a right-angle reducer 15, a drive shaft 13, and a side support plate 11. The side support plate 11 is fixed to the side of the housing, and a bearing seat 12 is provided on the support plate to support the drive shaft 13. The right-angle reducer 15 is fixed on the support frame 3. One end of the drive shaft 13 is connected to the input shaft of the right-angle reducer 15, and the other end is connected to the output shaft of the drive motor 4 through a belt drive assembly 16.

[0025] This design offers a more flexible transmission method, which can adjust the speed and output torque as needed to adapt to the mixing requirements of different types of materials; the belt drive method can reduce the burden on the drive system and avoid excessive power loss.

[0026] The upper end of the feed hopper 1 is provided with a fixing plate 10 on each side, and the fixing plate 10 has through holes on both sides. These through holes can be used to fix the feed hopper to other components by screws or other fixing devices, thereby ensuring the smooth entry of materials and the stability of the equipment. The design of the fixing plate enables the feed hopper to withstand a large material input pressure and avoids accidental deformation or loosening during the feeding process.

[0027] The structure of the feed hopper 1 allows the material to smoothly enter the mixing zone inside the shell; the design of the feed inlet is consistent with the upper center of the mixing rotary disc 5, so that after the material enters, it can be quickly and evenly distributed by the feeding blades 6, thereby improving the mixing efficiency.

[0028] In use: the proportioned materials are fed into the feed hopper 1 by a screw conveyor, and then enter the shell through the feed hopper 1 and flow smoothly into the mixing zone; the drive motor 4 drives the mixing rotary disc 5 to rotate through the right angle reducer 15 and the transmission shaft 13; the material-dispersing blades 6 on the mixing disc stir the materials as the disc rotates, and push the materials to tumble in the shell; the material-dispersing blades 6 disperse and tumble the materials, so that they are evenly distributed in the mixing zone, ensuring that the materials are fully mixed; after the materials are fully mixed, with the help of the conical structure design of the lower shell 9, the materials are smoothly discharged through the discharge port 14, completing the mixing process.

[0029] The foregoing has shown and described the basic principles, main features and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this utility model as claimed.
