Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a double-shaft high-efficiency mixer. Background Art

[0002] The twin-shaft mixer is a commonly used mixing equipment, widely used in various industries, such as chemical industry, metallurgy, food, medicine and building materials. Its working principle is basically to use the rotation of the twin shafts in the mixing barrel to achieve the mixing effect. The twin-shaft mixer uses the synchronous rotation of two symmetrical spiral shafts to add water and stir while conveying dry ash and other powdered materials, and evenly humidifies the dry ash and powdered materials to achieve the purpose of preventing the humidified materials from emitting dry ash and leaking water droplets, thereby facilitating the loading and transportation of the humidified ash or transferring it to other conveying equipment.

[0003] However, the following problems still exist in actual use:

[0004] (1) When the existing twin-shaft mixer is in use, after the device completes stirring of the materials inside it, some of the stirring material residue will adhere to the inner wall, which still needs to be manually processed, resulting in the device being unable to quickly stir the next batch of materials, thereby causing the twin-shaft mixer to have a low stirring efficiency.

[0005] (2) When the existing twin-shaft mixer is in use, the stirring paddles in the device are mostly fixedly connected to the rotating shaft, and thus they will wear out during long-term use of the device, resulting in increased resistance during stirring, making it impossible to fully clamp the materials, and it is not convenient to repair them, resulting in the problem of low practicality of the twin-shaft mixer.

[0006] For this reason, the utility model launches a double-shaft high-efficiency mixer. Utility Model Content
