Description

Technical Field

[0001] This utility model belongs to the field of composite material molding pretreatment technology, specifically relating to a mixer with convenient material discharge. Background Technology

[0002] In the fields of mineral, polymer, and biological composite material testing and small-scale production, it is often necessary to pre-treat and homogenize multiple raw materials. Powder mixing equipment often adopts a U-shaped mixing chamber structure. These mixers typically rely on the combined action of an agitator within the chamber and guide vanes on the chamber walls to achieve uniform material mixing. To ensure the stability of equipment operation, the mixer base is usually designed with a counterweight structure, and the mixing chamber and base are fixedly connected.

[0003] However, the above structure has significant drawbacks: the discharge path for the powder is limited. After mixing, the material can only be manually cleaned through the opening at the top of the mixing chamber or discharged using a pre-installed discharge mechanism on the chamber. Particularly noteworthy is the presence of the stirring paddle and its supporting structure, which creates numerous hard-to-reach physical dead zones inside the mixing chamber. These areas are prone to powder residue and are difficult to clean thoroughly.

[0004] The long-term accumulation of residual materials not only leads to material waste, but more seriously, it can contaminate subsequent batches of different component powders, causing inaccurate mixing ratios and severely affecting the consistency of product quality and the reliability of experimental / production results. This problem is particularly prominent in scenarios requiring high-precision mixing or handling expensive materials that are prone to cross-contamination. Therefore, there is an urgent need for a mixer structure that can effectively solve the problem of residues in the dead corners inside the mixing chamber and achieve thorough clean discharge. Utility Model Content

[0005] In order to overcome the problems existing in the background technology, this utility model provides a mixer with convenient material discharge.
