Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure homogenizers, in particular to a high-pressure homogenizer with ultrasonic waves. Background Art

[0002] High-pressure homogenizer is a device that uses high pressure and high-speed shearing to homogenize materials in a suspended liquid state. High-pressure homogenizer includes a plunger pump, a homogenizing chamber and a homogenizing valve. The plunger pump uses the reciprocating motion of the plunger to generate high-pressure fluid to transport the material to the homogenizing chamber. The homogenizing chamber is the part where the material is homogenized. The homogenizing valve is a key component for homogenization, usually composed of a valve seat, a valve core and an impact ring.

[0003] When the homogenizer is processing materials, if the materials are not mixed evenly and the local concentration is too high, it is easy to get blocked. During the processing of materials in the homogenizer, due to the effects of extrusion, shearing, impact, etc., the internal molecules of the materials are constantly moving and rubbing, thus generating heat. Excessive temperature may cause the material to deteriorate. Utility Model Content
