Description

Technical Field

[0001] The utility model relates to the technical field of sweeping nozzles, in particular to a sweeping nozzle with adjustable blowing efficiency. Background Art

[0002] Industrial nozzles are mostly installed in various spraying, atomizing, oil spraying, sandblasting, spraying and other equipment, playing different roles, and widely used in environmental protection, coating pretreatment, circuit boards, petroleum, chemical industry, steel, metallurgy, electronics, cement, food, papermaking, printing, agriculture and animal husbandry and other industries, which can be said to be everywhere. However, the common nozzles on the market usually have a single function, do not have the function of adjusting the airflow size, and are not convenient for flexible regulation during use.

[0003] For example, a purging nozzle disclosed in the authorization announcement number CN202933815U belongs to an industrial purging nozzle, which is mainly used for purging and removing dirt in chemical pipelines, instrument pipelines, and industrial heat exchangers. It is characterized in that the nozzle head, the front section of the nozzle, the middle section of the nozzle and the rear section of the nozzle are integrated into a concentric shaft structure, and a through hole front section and a nozzle through hole are provided at the axis of the purging nozzle. Between the front section of the nozzle and the rear section of the nozzle is the middle section of the nozzle with a thinner outer diameter, and a groove is formed, and the nozzle head is provided with an external thread. The inner diameter of the frontmost spray hole of the through hole front section is the smallest, and the inner diameter of the rearmost is the same as the inner diameter of the nozzle through hole, and an internal thread is provided at the rear of the nozzle through hole. It is characterized in that the structure is simple, the connection is convenient, the jet of the spray hole is concentrated, and the purging effect is good. However, the utility model lacks airflow adjustment measures, which is not convenient for the staff to flexibly adjust according to different usage conditions. For this reason, we propose an adjustable blowing efficiency purging nozzle, which solves the problem of airflow adjustment and improves the flexibility and practical effect of the nozzle.
