Chinese utility model patent cn200920289528.x discloses a modular blast pipe radiation shield, including outer bellows, the inside lining of inlayer and the fixed end cover of setting at the radiation shield both ends, the internal surface of bellows cooperatees with the surface of inside lining, and the surface of bellows cooperatees with the inboard of fixed end cover, and the bellows skin adopts the aluminium foil to make, and the inlayer adopts glass fiber material to make, and the inside lining adopts inorganic fiber cotton thermal insulation material to make, and thermal-insulated effect is better, insulating layer surface temperature is lower, and occupation space is less moreover, and the installation is arranged simply, be difficult for droing, and the reliability is higher. But the corrugated pipe has uneven appearance, and in addition, the installation mode needs auxiliary equipment such as a binding band and the like for wrapping, so that time and labor are wasted; or through the fixed of multi-piece concatenation welding, it is long, the procedure is complicated, has the shortcoming such as the welding seam is many, the outward appearance is poor simultaneously, and one-time welding through the turn-ups then has the laminating poor, and turn-ups department pricks the hand and easy fish tail scheduling problem.

To sum up, to the problem that the outward appearance is irregular, the welding seam is many, easy fish tail operating personnel and the heat preservation effect is not good etc, need a simple structure, the installation is convenient, the heat shield that the thermal-insulated effectual and operation is safe that keeps warm.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a turn-ups keeps warm and separates heat exchanger can solve the problem that current exhaust duct separates heat exchanger.

For this purpose, the utility model is implemented by the following technical scheme.

A flanged insulation heat shield comprising: first turn-ups, second turn-ups, third turn-ups, the cover body.

The cover body is a pipe body, an opening is formed in the side wall of the pipe body along the axis direction, one end of the opening is turned over towards the outer side of the cover body to form the first turned edge, the other end of the opening is turned over twice to form a Z-shaped structure, the middle section of the Z-shaped structure is the second turned edge, and the tail section of the Z-shaped structure is the third turned edge.

Further, the first flanging and the second flanging are arranged in parallel and welded into a whole.

Furthermore, the third flanging is turned inwards and is covered on the first flanging and is welded with the first flanging into a whole.

Furthermore, the first flanging, the second flanging and the third flanging which are welded into a whole are turned over and pressed downwards towards one side where the third flanging is located, so that one side surface of the third flanging is attached to the outer surface of the cover body.

Further, the folding angle of each turn-ups is 90.

Further, the cover body is made of a stainless steel corrugated plate.

The utility model has the advantages of as follows:

1. the utility model discloses a separate heat exchanger simple structure and pleasing to the eye.

2. The utility model discloses the design does, and the one end of the cover body sharpness is as first turn-ups, does not expose by second turn-ups and third turn-ups cladding, can prevent the condition of scratch operating personnel, avoids producing danger.

3. The utility model relates to a first turn-ups welds as an organic wholely with the second turn-ups, welds the cladding of third turn-ups in the first turn-ups outside afterwards, makes single link carry out twice welding, can make thermal-insulated cover more firm, and the leakproofness is better.
