Problems solved by technology

At present, the existing brick chimneys cannot meet the needs of modern residents' lives because of their inconvenient use.
However, the existing metal chimneys are mostly made of stainless steel, with poor acid resistance and corrosion resistance, short service life, poor heat insulation effect, unreasonable structural design, inconvenient installation and use, and inconvenient flue arrangement.

Embodiment Construction

[0026] In order to make it easy to understand the technical means, creative features, goals and effects achieved by the present invention, the present invention will be further explained in conjunction with the embodiments below.

[0027] A chimney for an acid-alkali-resistant fireplace. The chimney is a hollow cylindrical double-layer structure composed of an inner layer and an outer layer. A gap is left between the inner layer and the outer layer, and the inner layer and the outer layer are at both ends Connected together, the inner layer is an anti-corrosion layer;

[0028] The inner layer is composed of the following parts by weight of raw materials:

[0029] Carbon 1.7%-2.2%, silicon 1.3%-1.6%, manganese 0.03%-0.06%, sulfur 0.02%-0.04%, magnesium 0.03%-0.07%, zinc 0.04%-0.08%, chromium 0.05%-0.07%, copper 0.04%-0.06%, cerium 0.02%-0.05%, rhenium 0.03%-0.06%, aluminum nitride 0.01%-0.03%, zinc oxide 0.02%-0.05%, titanium dioxide 0.02%-0.06%, glass fiber 0.03-0.07% , Nickel-zinc...

Abstract

The invention discloses an acid-base-resistant chimney for a fireplace. The chimney is of a hollow cylindrical double-layer structure and is composed of an inner layer and an outer layer, a gap is reserved between the inner layer and the outer layer, the inner layer and the outer layer are connected at two ends, and the inner layer is an anti-corrosion layer. The inner layer is formed by carbon, silicon, manganese, sulfur, magnesium, zinc and the like according to a certain ratio. The chimney is arranged to be of a double-layer structure and is made of the specific materials according to a certain ratio, and therefore the chimney has the advantages that the acid-base resistance is high, the corrosion resistance is high and the service life is long.

Description

Technical field [0001] The invention relates to the technical field of fireplaces, in particular to a chimney for acid and alkali resistant fireplaces. Background technique [0002] Fireplace is a kind of equipment for heating indoors by making a fire built against the wall. The fireplace was originally used in Western countries and has decorative effects and practical value. The basic structure of the fireplace includes: a mantel and a fireplace core. The mantelpiece plays a decorative role, and the fireplace core plays a practical role. Usually the installation of the fireplace depends on the structure of the house itself. For modern fireplaces, there are generally two types, one is a steel structure fireplace, which is generally produced in batches by a factory, and the other is a masonry fireplace, which is made by hand. Make. Steel fireplaces are currently more common and easy to install. The installer only needs to directly discharge the fireplace to a reserved place in...
