Description

Technical Field

[0001] This utility model relates to the field of mud gun nozzle technology, specifically a precision mud gun nozzle. Background Technology

[0002] Mud gun nozzles are widely used in various industries such as oil drilling, building ceramics, and metallurgy. In oil drilling operations, mud gun nozzles play a crucial role by injecting high-pressure mud to impact the bottom of the drilling mud tank, effectively reducing sedimentation and preventing mud deposits from affecting drilling operations. In the building ceramics industry, mud gun nozzles are used to pressurize mud of a certain concentration using a mud pump and spray it out in a mist form. This mist exchanges heat with hot air, drying the wet mud droplets into powder. In the metallurgical industry, such as during ladle construction, mud gun nozzles are used to precisely inject mud, ensuring the quality of the ladle construction.

[0003] In response, Chinese patent application number CN202020775131.8 discloses a mud gun, including a gun body and a connecting flange at one end. A water-blocking ring is fixedly fitted on the peripheral wall of the gun body at the end away from the connecting flange. Multiple water outlet holes are opened on the peripheral wall of the gun body between the water-blocking ring and the connecting flange. A water-collecting ring is fixedly fitted on the peripheral wall of the gun body at the water outlet holes. A water-collecting cavity communicating with the multiple water outlet holes is opened at the end of the water-collecting ring away from the connecting flange. A water spraying slit is formed between the end faces of the water-collecting ring and the water-blocking ring that are close to each other.
