Abstract
Description
Technical Field
[0001] The utility model relates to a technical field, in particular to an exhaust pipe with a heat insulation structure. Background Art
[0002] My existing patent (ZL2015203329311) is an exhaust pipe insulation device, including an insulation belt and a fixing device, characterized in that the insulation belt adopts a ceramic fiber belt with reinforcing wire inside, and the fixing device can adopt a combination of one or more of a stainless steel clamp, a tie, and a stainless steel wire. The insulation belt is wrapped on the exhaust pipe and fixed by the fixing device. The ceramic fiber belt adopts a ceramic material with a standard classification temperature of 1260 degrees, and the reinforcing wire adopts SUS304 metal wire and alkali-free glass fiber wire. However, with the advancement of science and technology, the above patent also needs to be further optimized. Therefore, a new exhaust pipe with an insulation structure is proposed here. Utility Model Content
[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide an exhaust pipe with a heat insulation structure.
[0004] According to the technical solution provided in the embodiment of the present application, an exhaust pipe with a heat insulation structure includes an exhaust pipe, wherein a glass fiber layer is arranged outside the exhaust pipe, and several layers of heat insulation cloth layers are wrapped around the outside of the glass fiber layer. The glass fiber layer and the heat insulation cloth layer are tightly wrapped and fixed by binding tape, and then a sleeve is put on the outside.
[0005] In the utility model, the diameter of a single glass fiber in the glass fiber layer is between 2 microns and 6 microns.
[0006] In the utility model, the thickness of the heat insulating cloth layer is between 0.1 mm and 10 mm, and the width is between 300 mm and 5000 mm.
[0007] In the utility model, the thickness of the binding strap is between 0.1 mm and 10 mm, and the width is between 10 mm and 300 mm.
[0008] In the utility model, the sleeve has a thickness of 0.1 mm to 10 mm and a diameter of 5 mm to 1000 mm.
[0009] In summary, the beneficial effects of the present application are as follows: the requirement of temperature resistance above 1000 degrees is met. At the same time, the hollow structure inside the fiber is retained to retain its good heat insulation effect, while being light in weight and occupying little space.

[0016] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.
[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0018] like Figure 1 As shown, the glass fiber layer 2 uses glass fibers with a diameter of less than or equal to 6 microns as the basic material, and such glass fibers include but are not limited to all types of glass fibers such as alkali-free glass fibers, medium-alkali glass fibers, high-alkali glass fibers, and high-strength glass fibers. The glass fibers used as the basic material are made into yarns (with a fineness of 100 tex to 5000 tex) through a conventional weaving process, and then woven into the glass fiber layer 2, which is resistant to high temperatures of 1200 degrees.
[0019] The heat-insulating cloth layer 3 is woven from the same yarn as the glass fiber layer 2, with a thickness of 0.1 mm to 10 mm and a width of 300 mm to 5000 mm.
[0020] The binding strap 4 is woven from the same yarn as the glass fiber layer 2, and there are 2 to 5 straps, with a thickness of 0.1 mm to 10 mm and a width of 10 mm to 300 mm.
[0021] The above 4 layers of materials (excluding yarn) must be treated with acids including but not limited to hydrochloric acid, sulfuric acid, nitric acid and other acids to make the silica content exceed 50% or the operating temperature exceed 700 degrees or above.
[0022] like Figure 2 and Figure 3As shown, the sleeve 5 can be divided into two parts, the upper and lower parts, which are combined and locked by means of buckles or screws. An array of tiny heat dissipating fins 6 are provided on the sleeve 5. The tiny heat dissipating fins 6 form an angle of 30 degrees with the X-axis, and the inclination directions of the adjacent tiny heat dissipating fins 6 on both sides are opposite, thereby increasing the heat dissipation effect.
[0023] The above layers are sequentially bundled on the exhaust pipe 1 from the inside to the outside, namely, the glass fiber layer 2, the heat insulation cloth layer 3, the binding tape 4 and the sleeve 5.
[0024] In this solution, the heat insulation device can be used in heat-bearing structures such as exhaust pipes and hot water pipes in addition to exhaust pipes to prevent users from being scalded. In this solution, the sleeve 5 of different materials can be replaced according to the situation, so that it can adapt to different application environments.
[0025] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the utility model involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also includes other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) to form a technical scheme.
