Description

Technical Field

[0002] Cellulose ether is a high molecular compound that is soluble in water, dilute alkaline solution and organic solvent, and has thermoplasticity and excellent performance. It is widely used in industries such as construction, cement, petroleum, food, textiles, detergents, coatings, medicine, papermaking and electronic components.

[0004] Although current equipment can achieve effective mixing of cellulose ethers, there are still some problems in daily use. When the cellulose ether raw materials are exposed to moisture, excessive pressure or excessive moisture absorption during the storage stage, resulting in the raw material particles sticking together into agglomerates, the mixing difficulty increases significantly. At this time, when using the existing high-pressure airflow mixing system, the internal structure of the agglomerates is compact and the external airflow is difficult to penetrate deeply, so the mixing effect is greatly reduced and the ideal uniformity cannot be achieved. In addition, the single mixing structure design adopted has certain limitations in its mixing efficiency when dealing with complex and changeable cellulose ether production needs. In particular, when processing large amounts of highly viscous or easily agglomerated cellulose ether raw materials, a single airflow impact may not be able to fully mobilize all raw material particles to participate in efficient mixing, resulting in a slow overall mixing process. Utility Model Content

When processing large amounts of highly viscous or easily agglomerated cellulose ether raw materials, all raw material particles can be fully mobilized to participate in efficient mixing, thereby accelerating the cellulose ether mixing process.

[0006] In order to solve the above technical problems, the utility model provides an airflow mixer, including an airflow mixing shell and mounting holes which are evenly arranged in an annular shape at the lower end of the outer arc surface of the airflow mixing shell, high-pressure gas nozzles are arranged in the mounting holes, and a breaking mechanism is arranged at the lower end of the inner cavity of the airflow mixing shell, the breaking mechanism includes an assembly groove arranged at the lower end of the inner cavity of the airflow mixing shell, a rotating ring is rotatably connected in the assembly groove, rotating rods are rotatably connected in rotating holes which are evenly arranged in an annular shape at the lower end of the outer arc surface of the rotating ring, and breaking frames are arranged on the inner ends of the rotating rods, and a driving assembly for driving the rotating rod to rotate is also provided on the bottom wall of the assembly groove, a driving module for driving the rotating ring to rotate is also provided at the lower right end of the airflow mixing shell, and a sealing assembly is also provided at the lower end of the inner cavity of the airflow mixing shell.

[0013] Relevant staff control the operation of the motor through an external single-chip computer.
