AI Technical Summary

Technical Problem

The existing TBM dust removal fan will pass through when the filter is not cleaned for a long time, and a large amount of heat is generated when the fan works, resulting in a harsh working environment, the existing atomization device has a simple structure and uneven cooling and dust reduction effect.

Method used

A device with a conical structure and a two-stage connection structure is designed, with a swingable array atomization nozzle, which is installed at the fan outlet through a conical sleeve, and the atomization nozzle is swung by a driving motor to form a full-coverage water mist curtain for cooling and dust reduction.

Benefits of technology

The TBM dust collector air outlet is fully covered and cooled and dust-reduced, which improves the working environment and improves the uniformity and effect of cooling and dust-reducing.

Abstract

The invention discloses a TBM dust removal fan air outlet cooling and dust removal device, and relates to the technical field of dust removal fan external auxiliary devices. A conical sleeve is integrally formed and arranged on a rear end opening of an air outlet sleeve, and a mounting frame is fixedly arranged on the inner side wall of the conical sleeve; the two mounting shafts are arranged on the front inner side wall and the rear inner side wall of the mounting frame in a bilateral symmetry mode through bearings in a screwed connection mode, the multiple supporting frames in one set are fixedly arranged on the mounting shafts in an equal-angle distribution mode, the atomizing nozzles are arranged at the ends, away from the mounting shafts, of the supporting frames, the base is arranged behind the connecting sleeve, and the base plate is fixedly arranged outside the base in a sleeving mode; the connecting plate is sleeved and fixed on the air outlet sleeve; according to the device, the conical structure and the two-section type connecting structure are arranged, so that the device can be in butt joint with air outlets of dust removal fans of different models, a plurality of groups of atomizers capable of swinging are further arranged in the conical structure of the device, and therefore covering spraying aiming at the inner section of the conical structure is achieved, and cooling and dust falling of air blown out of the fans are achieved.
