[0002] The discharge structure of the homogenization and deodorization system is a type of negative pressure deodorization and homogenization silo. The silos include silos in the chemical, building materials, grain, fertilizer and other industries. Its advantages include good deodorization effect, energy saving and environmental protection, easy operation and wide applicability. It is an important equipment in the production of plastic products.

However, the bottom of the hopper is easily blocked after the valve is closed, resulting in the problem of material failure. At the same time, the different particle sizes of the materials also make it easy to control the discharge rate.

[0004] Based on this, a discharging structure for a homogenizing and deodorizing system is designed. Utility Model Content
