Description

TECHNICAL FIELD

[0002] The mixer is a kind of equipment that different materials are mixed, stirred or homogenized by mechanical force, and its core function is to realize the efficient mixing of materials by rotating blade or stirring device. The mixer is usually composed of rotating shaft with blade, driving device and container (such as cylinder or tank), and the uniform mixing of materials is realized by the shearing force, convection and diffusion effect generated by blade rotation.

[0003] When the mixer discharges after mixing materials, the materials may be too viscous or dry, and the flowability is poor, so the materials may be accumulated and blocked at the discharge port. Therefore, a anti-blocking mechanism is usually installed on the mixer. The traditional method is usually to promote the flow of materials by external impact or vibration equipment. The vibration may aggravate the wear of the bin body, and frequent maintenance is required for long-term use. Moreover, the effect on deep blockage is not good, and manual intervention is still required. The dredging effect is not good, or the stirring cylinder, blade and other components are disassembled after power failure, and the residual materials are manually cleaned. It is not only low in efficiency but also high in labor intensity, especially in industrial scene, frequent shutdown is required, which affects the continuity of production. UTILITARIAN CONTENT
