Description

A heat-insulated exhaust pipe opening

technical field

The utility model relates to an accessory of a ship's pipeline, in particular to a heat-insulating exhaust pipe opening.

Background technique

Most ships are powered by the combustion of diesel or other fuels, and the exhaust pipes used to discharge exhaust gases generally need to pass through the bulkhead and connect to the chimney. At this time, it is necessary to properly install the exhaust pipe opening to pass through the bulkhead, but the temperature of the exhaust pipe is generally high, and the use of ordinary openings cannot protect the bulkhead. An existing Chinese patent with application number 201410109906.7 discloses "A Simple Exhaust Pipe Opening Part", which includes a open cabin part and a single-sided seat plate welded by an exhaust pipe, a flange and an intermediate flange. On the bulkhead and the single-side seat plate, a through hole matching the through-cabin fitting is opened, the single-side seat plate is welded on the bulkhead, and the through-cabin piece is fixed on the single-side seat plate by bolts. A sealing gasket is provided, and the outer part of the cabin is covered with heat-insulating material. Although the cabin parts made in this way can achieve the effect of heat insulation and sealing, the structure is relatively complicated, and the cooperation of various parts is required, which also increases the processing difficulty and increases the production cost. Also have a Chinese patent that application number is 201120089374.7 to disclose " the deck pass-through part of ship pipeline ", and it comprises pass-through steel pipe, flange, sleeve pipe and web, is welded with flange on the both end faces of pass-through steel pipe, The casing is fixed on the steel pipe through the cabin, the web is loosely sleeved on the steel pipe through the cabin, and then the web is welded on the bulkhead and fixed, and a heat insulation layer is provided between the inner control of the casing and the outer wall of the steel pipe through the cabin. This cabin-passing part has a simple structure and is easy to weld, but the heat insulation layer provided by it is only aimed at the heat generated during welding, and cannot effectively protect the bulkhead.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide a heat-insulated exhaust pipe opening which has a simple structure, is easy to manufacture, and can effectively prevent the bulkhead from being deformed by heat and ensure watertightness.

The technical scheme adopted by the utility model is: the utility model comprises a cabin pipe, a flange and a web, the flanges are fixedly arranged at the front and rear ends of the cabin pipe respectively, and the web is fixedly arranged at the The left and right ends of the through-cabin pipe are fixed on the bulkhead, and a heat-insulating layer is arranged inside the through-cabin pipe, and the heat-insulating layer is filled with heat-insulating filler.

Preferably, the outer diameter of the flange is larger than the outer diameter of the tank pipe, and the bulkhead is provided with a through hole corresponding to the outer diameter of the flange, and the bulkhead is connected to the through hole. There are gaps between the tank tubes.

Preferably, several square steels are fixedly arranged on the two inner walls before and after the tank passage.

Preferably, a gasket is also provided at the connection between the flange and the tank pipe.

Preferably, the heat insulating filler may be aluminum silicate.

The beneficial effects of the utility model are: since the utility model comprises a cabin pipe, a flange and a web, the flanges are fixedly arranged at the front and rear ends of the cabin pipe respectively, and the web is fixedly arranged on the The left and right ends of the through-cabin pipe are fixed on the bulkhead, and a heat-insulating layer is arranged inside the through-cabin pipe, and the heat-insulating layer is filled with heat-insulating filler. When the utility model is used, the web is welded on the bulkhead instead of the direct welding of the tank pipe, which can improve the welding quality, and the heat insulation layer can effectively protect the bulkhead from High thermal influence of the exhaust pipe. Therefore, the utility model has the advantages of simple structure, high welding quality and effective protection of the bulkhead from thermal deformation.

Since the outer diameter of the flange is greater than the outer diameter of the tank pipe, the bulkhead is provided with a through hole corresponding to the outer diameter of the flange, and the bulkhead and the tank tube There are gaps in between. In this way, there is a certain space between the flange and the bulkhead, the tank pipe and the bulkhead, which is convenient for operation when the flange is connected or disassembled with the external pipeline; The bulkhead is in direct contact with the vent pipe, further protecting the bulkhead.

Because some square steels are also fixedly arranged on the two inner walls before and after the hatch pipe. Several square steels play a role in strengthening and stabilizing the inside of the hatch pipe, so the durability of the utility model is improved.

Because a gasket is also provided at the connection between the flange and the tank pipe. The gasket reduces the gap between the flange and the hatch pipe, improving the sealing performance of the utility model.

Because the heat-insulating filler can be aluminum silicate and other heat-insulating materials. The heat insulating filler effectively prevents the heat in the exhaust pipe from spreading outwards and protects the bulkhead.

Detailed ways

As shown in Fig. 1, the utility model comprises a cabin pipe 1, flanges 2 are welded on the front and rear ends of the cabin pipe 1, and the outer diameter of the flange 2 is larger than that of the cabin pipe. 1, and the connection between the flange 2 and the tank pipe 1 is provided with a gasket 6. In this embodiment, the gasket 6 is selected from a spring washer or a flat washer to maintain the utility model. water tightness. Webs 3 are welded on the left and right ends of the hatch tube 1 , and the webs 3 are welded at the middle positions of the left and right sides of the hatch tube. Open a through hole 41 corresponding to the size of the flange 2 on the bulkhead 4, pass the utility model through the through hole 41 to the web 3 and the bulkhead 4, and then place the The web 3 is welded to the bulkhead 4 and fixed. In this way, after the utility model is fixedly welded on the bulkhead 4, there is a certain gap between the through-cabin pipe 1 and the flange 2 and the bulkhead 4, which facilitates installation and welding or the flange 2 and the bulkhead 4. The operation when the external pipeline is connected and disassembled; and when the exhaust gas starts to discharge, the gap left can prevent the bulkhead 4 from being in direct contact with the cabin passage 1 , effectively preventing heat from spreading to the bulkhead 4 .

Several square steels 11 are also welded on the inside of the hatch pipe 1 , that is, the front and rear inner walls thereof, to increase the strength and durability of the hatch pipe 1 . And also leave heat-insulating layer 5 inside described cabin pipe 1, be filled with heat-insulating filler 51 in described heat-insulating layer 5, just can prevent the heat in exhaust pipe from distributing outwards like this, protect described as far as possible. Bulkhead 4, to avoid its thermal deformation. In this embodiment, the heat insulating filler 51 is made of aluminum silicate.

The materials used in the utility model are commonly used materials in the shipbuilding industry, and their size can be changed according to the size requirements of the ship or the exhaust pipe of the main and auxiliary engines during production, so as to meet the actual use conditions.

The utility model is suitable for the shipbuilding industry.
