Description

Chimney top prevents cigarette ash structure

Technical Field

The invention relates to a smoke and dust preventing structure at the top of a chimney.

Background

The chimney of a conventional ship has a top portion with peripheral walls extending upwardly a distance, and side portions with a good appearance and a slope (as shown in fig. 1). The chimney is made very high, typically exceeding the deck of the compass built on, and its main purpose is to prevent soot from falling into the living area. However, due to the feedback of many shippers, the soot at the tail of the chimney can fall to the tail deck area, and the environment is affected.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide the chimney top soot prevention structure, the shape of the chimney is simply changed, and the appearance is not influenced; the windward side is not increased in structural design, and the cost is not increased; the collection of the soot is maximized, and the protection of the ship environment is ensured.

In order to achieve the purpose, the technical scheme of the invention is to design a chimney top soot prevention structure, which comprises a chimney rear surrounding wall obliquely arranged with a horizontal plane; the detachable cigarette ash that is equipped with collects the ring on the inner wall of chimney, sets up the swash plate that is used for avoiding cigarette ash to fall the living area and is used for holding cigarette ash collection ring at the lower extreme of chimney back leg. The setting of collection ring can be regularly taken down in order to clear away the cigarette ash of gathering at the collection ring inner wall, and the swash plate can avoid chimney mouth department exhaust flue gas to subside into the ash after apart from chimney mouth one end distance, just so can fall on the swash plate, can avoid shaking off of cigarette ash when getting cigarette ash collection ring through the setting of swash plate when getting off cigarette ash collection ring moreover. Through the improvement to the leg behind the chimney, under the condition that does not increase the windward side area (because increase the windward side area, probably increase the outfitting number, lead to the cost to rise), with the design of back leg slope, increase the area that cigarette ash was collected, cigarette ash can concentrate the chimney top along the inclined plane simultaneously, is convenient for centralized processing. The appearance of the chimney is only changed simply, and the appearance is not influenced; the windward side is not increased in structural design, and the cost is not increased; the collection of the soot is maximized, and the protection of the ship environment is ensured.

A further technical scheme is that the cigarette ash collecting ring comprises two half rings, an L-shaped insert block is integrally arranged at one end of each half ring, and a blind hole-shaped inserting hole for inserting the L-shaped insert block is formed in the top wall of the chimney.

The further technical proposal is that the inclination directions of the chimney rear surrounding wall and the inclined plate are opposite; the number of the inclined plates is consistent with that of the chimneys.

The further technical proposal is that the inclined plate is fixedly arranged at the lower end of the chimney rear surrounding wall.

The other technical scheme is that the inclined plate is hinged at the lower end of the chimney rear surrounding wall. When the ash collecting ring is not taken out, the inclined plate is turned upwards to lean against the surface of the rear wall of the chimney, so that the increase of the frontal area is avoided.

The further technical scheme is that a dust baffle plate is hinged to the chimney rear surrounding wall, and the hinged position of the dust baffle plate is located on the upper portion of the chimney rear surrounding wall.

The invention has the advantages and beneficial effects that: the setting of collection ring can be regularly taken down in order to clear away the cigarette ash of gathering at the collection ring inner wall, and the swash plate can avoid chimney mouth department exhaust flue gas to subside into the ash after apart from chimney mouth one end distance, just so can fall on the swash plate, can avoid shaking off of cigarette ash when getting cigarette ash collection ring through the setting of swash plate when getting off cigarette ash collection ring moreover. When the ash collecting ring is not taken out, the inclined plate is turned upwards to lean against the surface of the rear wall of the chimney, so that the frontal area is prevented from increasing. Through the improvement to the leg behind the chimney, under the condition that does not increase the windward side area (because increase the windward side area, probably increase the outfitting number, lead to the cost to rise), with the design of back leg slope, increase the area that cigarette ash was collected, cigarette ash can concentrate the chimney top along the inclined plane simultaneously, is convenient for centralized processing. The appearance of the chimney is only changed simply, and the appearance is not influenced; the windward side is not increased in structural design, and the cost is not increased; the collection of the soot is maximized, and the protection of the ship environment is ensured.
