Air blowing ring

Abstract

The invention publishes a ring which may huff. Specifically speaking, it is a ring which besmears the pickling oil and the anti-rusting paint on the surface of the circular pipe or the rods and bars and so on. It includes the inner ring and the outer ring, inner rim's diameter is smaller than the outer ring, in order to make a spacing between them; the ends extend in a go-and-return opposite direction, one end connect assumes the seal shape connection, the other end has a ring-like slit. The extension line of the ring-like slit outward is a cone. Out of the ring sidewall has the air inlet. Its characteristic is that both sides of the outer ring have a ring-like inside lug boss, the inner rim's end has a ring-like outside lug boss, the inner rim which don't have a ring-like outside lug boss end enters in the outer ring, and the ring-like outside lug boss which is located at an inner rim end connect together with the ring-like lug boss which at the same location at the outside rim with bolts. With this gas-blow ring, it is not only energy conservation and the pickling oil or the anti-rusting paint, but also enhances the effect of the pickling oil or the anti-rusting paint smudges.

Description

technical field [0001] The invention relates to a spraying machine. Specifically, it is an air blowing ring for spraying antirust oil or antirust paint onto the surface of round pipes or rods. Background technique [0002] It is known in the pipe or bar production industry that in order to prevent the surface of the pipe or bar from being oxidized during storage or transportation, it is often necessary to coat a layer of anti-rust oil or anti-rust paint on the outer surface of the pipe or bar. The usual production method is to use compressed gas to atomize and spray anti-rust oil or anti-rust paint through several special nozzles to the surface of pipes or rods in linear motion. In order to make the thickness of the anti-rust oil or anti-rust paint sprayed on the surface of the pipe or bar uniform, the spraying equipment is also equipped with a blowing ring to clean the anti-rust oil or anti-rust paint on the surface of the pipe or bar in motion. The paint is blown and wip...

AI Technical Summary

Problems solved by technology

Since one end of the inner and outer rings without annular gaps is threaded, there will inevitably be a fitting gap between the inner and outer threads, so that the compressed air entering the inner and outer rings will leak from the fitting gap, which will not only waste energy, but also affect Blow-and-smear effect of anti-rust oil or anti-rust paint

And because there is no annular gap between the inner and outer rings, one end is threaded, once the axis of the thread deviates from the center line, the width of each point of the annular gap will be uneven, so that the ejected annular airflow will be uneven at each point, and it is difficult to make the pipe or rod The anti-rust oil or anti-rust paint on each point on the surface of the material is blown evenly

In this way, not only will the anti-rust oil or anti-rust paint be wasted, but also affect the blowing effect of the anti-rust oil or anti-rust paint
