Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection, in particular to a waste heat power generation pipeline provided with a protection structure. Background Art

[0002] Waste heat refers to thermal energy that can be used but is not used. Waste heat power generation is to recycle the wasted heat energy for power generation, thereby improving energy utilization, reducing production costs and protecting the environment.

[0003] In the high-temperature waste liquid and waste gas transportation pipelines used for waste heat power generation, the thermal insulation effect of the pipelines is particularly important.

[0004] Existing pipeline insulation measures generally use insulation film for wrapping and covering, which is not only troublesome to install, but also when the pipeline needs to be inspected and repaired, the insulation structure can only be violently dismantled, and the reuse rate of resources is low.

[0005] For this reason, we propose a waste heat power generation pipeline with a protective structure to solve the existing problems. Utility Model Content

[0006] The utility model aims to solve the problems existing in the background technology and proposes a waste heat power generation pipeline with a protective structure.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waste heat power generation pipeline with a protective structure, comprising a pipe body, a foam sleeve, a buckle strip and a positioning block, the outer surface of the pipe body is symmetrically provided with buckle strips, two of the foam sleeves are buckled on the two buckle strips, and the outer surfaces of the two foam sleeves are wrapped and installed with spiral winding belts.

[0008] Preferably, a seat is symmetrically glued to the outer surface of the tube body, and the buckle strip is installed on the seat.

[0009] Preferably, a buckle groove matched with the buckle strip is formed on the inner surface of the foam sleeve, and the buckle strip is inserted into the buckle groove.

[0010] Preferably, a positioning groove adapted to the positioning block is provided at the end surface of the foam sleeve;

[0011] The two sides of the single positioning block are respectively inserted into the positioning grooves of the end surfaces of the two foam sleeves.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] During the use of the waste heat power generation pipeline of the protection structure of the utility model, the cushion seat carrying the buckle strip can be glued to the waste heat power generation pipeline that needs thermal insulation protection, and then two semicircular foam sleeves are clamped on the buckle strip by plastic deformation, so that the foam sleeves form a whole to insulate the pipe body. Through the design of the cushion seat, the cushion seat separates most of the inner wall of the foam sleeve from the outer wall of the pipe body, so that a certain amount of air is fixed in the gap between the inner wall of the foam sleeve and the outer wall of the pipe body to form an insulation layer;

[0014] Furthermore, when the two foam sleeves are brought closer to each other, the positioning block is inserted into the foam sleeve, and the connection between the two foam sleeves is stabilized by the friction between the positioning block and the foam sleeve;

[0015] Finally, a layer of spiral wrapping tape is wrapped around the surface of the foam sleeve. The wrapping tape is made of modified PP polypropylene and can provide wear-resistant protection.

[0016] The utility model adopts a method of mutual clamping and positioning between structures, which not only plays a role in heat preservation and wear resistance of the waste heat power generation pipeline, but also makes it easy to dismantle the heat preservation structure, thereby improving the reuse rate of resources.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] like Figure 1-Figure 4 As shown, the utility model proposes a waste heat power generation pipeline with a protective structure, including a pipe body 1, a foam sleeve 2, a buckle strip 4 and a positioning block 5. The outer surface of the pipe body 1 is symmetrically provided with buckle strips 4, two foam sleeves 2 are buckled on the two buckle strips 4, and the outer surfaces of the two foam sleeves 2 are wrapped and installed with a spiral winding belt 3.

[0026] Based on Example 1:

[0027] During the use of the waste heat power generation pipeline of the protection structure of the utility model, the cushion seat 6 carrying the buckle strip 4 can be glued to the waste heat power generation pipeline that needs thermal insulation protection, and then the two semicircular foam sleeves 2 are clamped on the buckle strip 4 through plastic deformation, so that the foam sleeves 2 form a whole to insulate the pipe body 1;

[0028] The foam sleeve 2 is made of polystyrene foam. The expandable polystyrene foam board is a white object formed by pre-expanding expandable polystyrene beads containing a volatile liquid foaming agent and then heated in a mold. It has a fine closed-cell structure and has excellent thermal insulation performance.

[0029] Through the design of the cushion seat 6, the cushion seat 6 separates most of the inner wall of the foam sleeve 2 from the outer wall of the tube body 1, so that a certain amount of air is fixed in the gap between the inner wall of the foam sleeve 2 and the outer wall of the tube body 1 to form an insulation layer;

[0030] Furthermore, when the two foam sleeves 2 are brought closer to each other, the positioning block 5 is inserted into the foam sleeve 2, and the friction between the positioning block 5 and the foam sleeve 2 stabilizes the connection between the two foam sleeves 2.

[0031] Finally, a layer of spiral wrapping tape 3 is wrapped around the surface of the foam sleeve 2. The spiral wrapping tape is made of modified PP polypropylene and can provide wear-resistant protection.

[0034] The inner surface of the foam sleeve 2 is provided with a buckle groove 7 adapted to the buckle strip 4, and the buckle strip 4 is inserted into the buckle groove 7. The design of the buckle strip 4 and the buckle groove 7 utilizes the elastic deformation of the foam to make the two mutually clamped, thereby facilitating the installation and removal of the foam sleeve 2.

[0035] A positioning groove 8 matching with the positioning block 5 is provided at the end surface of the foam sleeve 2;

[0036] The two sides of a single positioning block 5 are respectively inserted into the positioning grooves 8 on the end faces of the two foam sleeves 2. When the two foam sleeves 2 approach each other, the positioning block 5 is inserted into the foam sleeves 2, and the friction between the positioning block 5 and the foam sleeves 2 stabilizes the connection relationship between the two foam sleeves 2.
