High-pressure jet impact chamber structure and multi-parallel type pulverizing component

A high-pressure jet impact chamber structure, comprising a body (11);

• wherein both ends of the body (11) along a length direction are an upstream end and a downstream end;
• an opening of the upstream end is configured to connect a supply portion, and an opening of the downstream end is configured to connect a discharge portion;
• a chamber is defined in the body (11) extending along the length direction and running through the upstream end and the downstream end;
• the chamber comprises a jet aperture (12) disposed at the upstream end and a pulverizing chamber (13) disposed at the downstream end that are in communication with each other;
• a flow size of the jet aperture (12) is the same as or smaller than a flow size of the pulverizing chamber (13);
• the pulverizing chamber (13) comprises a first inlet disposed at the upstream end and a first outlet disposed at the downstream end;
• a flow size of the pulverizing chamber (13) increases sequentially from the first inlet to the first outlet;
• an inner wall surface of the pulverizing chamber (13) is formed with a pulverizing portion for pulverizing;
• and wherein the pulverizing chamber (13) is of a rotary structure;
• the pulverizing portion comprises a plurality of protruding conical surfaces formed from the first inlet to the first outlet;
• a section of the pulverizing chamber (13) is serrated, and a chamfer is arranged at each of the first inlet and the first outlet.
