Description

A kind of simple stern heat insulator for discharge duct

Technical field

The utility model relates to heat insulator for discharge duct technical fields, fill more particularly to a kind of simple stern exhaust insulation It sets.

Background technique

Marine main engine and auxiliary exhaust pipe, which wear outside plate, need to reach water seal with the Ship Structure place of docking, so most of As soon as ship is all to require exhaust pipe in outlet setting crossing cabin part or directly welding, it is directly welded with a drawback Being that Tail Pipe Temperature is very high directly results in deck of boat peeling paint, the exhaust pipe of crossing cabin part is arranged, crossing cabin part pattern often uses water Cold (need to be equipped with cooling water pump, water pipe etc.) relative complex and cost is relatively high, therefore how preferably to slow down the high temperature of exhaust pipe Influence to cabin paint becomes urgent problem.

Utility model content

Technical problem to be solved in the utility model is how preferably to slow down the high temperature of exhaust pipe to paint cabin It influences.

In order to solve the above technical problems, the utility model provides a kind of simple stern heat insulator for discharge duct, including it is arranged Casing on the outside of exhaust pipe is equipped with thermal insulation layer, contradicts on the outside of bulkhead and described sleeve pipe between described sleeve pipe and exhaust pipe, described Casing, which is located between one end and exhaust pipe of outboard, is equipped with sealing plate, and there are gap, the sealing plates one between the other end and exhaust pipe End is fixedly connected with exhaust pipe, and the other end is fixedly connected with casing.

Technical effect: it is equipped with thermal insulation layer between the casing and exhaust pipe of the utility model setting, can largely be slowed down It is transferred to bulkhead between high temperature on exhaust pipe, sealing plate is equipped with since casing is located between one end and exhaust pipe of outboard, then arranges Heat on tracheae can be transferred on casing via sealing plate, due to casing between one end and bulkhead of sealing plate there are distance, Outboard is in outdoor, and the air energy of flow is effectively taken away the heat generated on sealing plate and casing due to heat transmitting, makes to be transferred to cabin Heat at wall is few, to be not easy to make the peeling paint on bulkhead, the casing length that the utility model is located at outboard is longer, dissipates Heat distance is bigger, and heat insulation is better, in addition, there are gaps between one end and exhaust pipe that casing is located at inboard, so that whole The point of a exhaust pipe energy heat transmitting only has at outboard sealing plate, can efficiently use outdoor air and radiate.

The technical solution that the utility model further limits is: the sealing plate is obliquely installed, and the sealing plate and exhaust pipe One end of connection is far from casing.

Further, described sleeve pipe is bilayer sleeve, and there are hollow sandwiches between the outer layer and internal layer of the bilayer sleeve.

A kind of preceding simple stern heat insulator for discharge duct, described sleeve pipe and sealing plate are made of seamless steel pipe.

A kind of preceding simple stern heat insulator for discharge duct, the thermal insulation layer is interior to be filled with ceramic wool.

A kind of preceding simple stern heat insulator for discharge duct, the ceramic wool is with a thickness of 50-100mm.

A kind of preceding simple stern heat insulator for discharge duct, the bulkhead and outside of sleeve are welded.

The beneficial effects of the utility model are:

(1) casing of the utility model is bilayer sleeve, further increases heat insulation using hollow sandwich；

(2) ceramic wool filled in the utility model thermal insulation layer, it can be ensured that the heat insulation of thermal insulation layer；

(3) the utility model welds bulkhead and outside of sleeve, it is ensured that watertightness prevents water via casing and bulkhead Between gap enter inboard.

Detailed description of the invention

Fig. 1 is the structural schematic diagram that the utility model is used to embody casing.

Wherein: 1, exhaust pipe；2, casing；21, sealing plate；22, hollow sandwich；3, gap；4, thermal insulation layer；5, bulkhead.

Specific embodiment

Embodiment: a kind of simple stern heat insulator for discharge duct, as shown in Figure 1, including the casing for being set in 1 outside of exhaust pipe 2, thermal insulation layer 4 is equipped between casing 2 and exhaust pipe 1, for inhibiting the heat transfer on exhaust pipe 1 to casing 2, in thermal insulation layer 4 Filled with ceramic wool, ceramic wool is with a thickness of 50-100mm, it can be ensured that the heat insulation of thermal insulation layer 4,2 outside of bulkhead 5 and casing Welding, due to the setting of thermal insulation layer 4, can largely reduce the heat that exhaust pipe 1 is transferred at bulkhead 5, to slow down cabin What wall 5 was painted falls off.

Casing 2 be located between one end and exhaust pipe 1 of outboard be equipped with sealing plate 21, between the other end and exhaust pipe 1 there are Gap 3,21 one end of sealing plate are fixedly connected with exhaust pipe 1, and the other end is fixedly connected with casing 2, and sealing plate 21 is obliquely installed, and sealing plate 21 The one end connecting with exhaust pipe 1 is far from casing 2, since the point of the entire 1 energy heat transmitting of exhaust pipe of the setting in gap 3 only has side of a ship covering At plate 21, since there are distance, outboard is in outdoor between casing 2 and bulkhead 5, the air energy of flow effectively take away sealing plate 21 and Due to the heat that heat transmitting generates on casing 2, keep the heat being transferred at bulkhead 5 few.

Casing 2 and sealing plate 21 are made of seamless steel pipe, and casing 2 is bilayer sleeve 2, the outer layer and internal layer of bilayer sleeve 2 Between there are hollow sandwiches 22, further increase heat insulation using hollow sandwich 22

In addition to the implementation, the utility model can also have other embodiments；It is all to use equivalent replacement or equivalent change The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
