[0021] 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.

[0022] See also Figure 1-5 The utility model provides an embodiment: a flame retardant and high temperature resistant smoke pipe, comprising:

[0023] The smoke pipe body 1 has connecting pipes 11 at both ends thereof, and the rigid metal structure is provided to facilitate the connection and positioning of the ends;

[0024] The dust-proof cloth bag 2 is sleeved on the outside of the smoke pipe body 1. Cloth bag rings 21 are evenly arranged on the dust-proof cloth bag 2, and a tightening rope 22 runs through the inside of the cloth bag ring 21. Through the cooperation of the cloth bag ring 21 and the tightening rope 22, the dust-proof cloth bag 2 can be tightened on the outside of the smoke pipe body 1, thereby improving the stability of its packaging and preventing it from falling off during use;

[0025] The positioning ring 3 is fixedly connected to the outer wall of the connecting tube 11. The positioning ring 3 is mainly provided for positioning. By tightening the end tightening rope 22, it is engaged inside the positioning ring 3 to prevent the tightening position from sliding randomly.

[0026] Furthermore, the smoke pipe body 1 includes an inner layer and an outer layer, and the inner layer is a stainless steel fiber layer and the outer layer is a high-temperature sandwich fabric layer. The connecting tube 11 is made of stainless steel, the inner layer of the smoke pipe body 1 is made of stainless steel fiber, and the outer layer of the smoke pipe body 1 is made of glass fiber. The bending radius of both materials is small and has a good sealing effect, thereby ensuring that smoke does not leak.

[0027] Furthermore, the outer diameter of the connecting tube 11 is equal to the inner diameter of the positioning ring 3, and the outer wall of the positioning ring 3 is an inward-recessed arc structure, and the diameter of the arc structure of the dust bag 2 is larger than the diameter of the tightening rope 22. Through the setting of the positioning ring 3, the bag ring 21 and the tightening rope 22 can be effectively assisted in positioning, and after the tightening rope 22 is tightened, it is engaged in the inside of the arc structure of the dust bag 2 to ensure its positioning stability, thereby preventing it from sliding after being tightened.

[0028] Furthermore, the main material of the dust bag 2 is polyester, which has good heat resistance and good wear resistance, effectively improving the service life of the device, avoiding its damage frequency, thereby reducing its maintenance frequency, and effectively reducing maintenance costs. The bag ring 21 is a hollow structure, and a threading hole is opened on the outside of the bag ring 21.

[0029] Furthermore, the cloth bag rings 21 at both ends are engaged in the interior of the arc structure of the positioning ring 3, and the inner wall of the arc structure of the positioning ring 3 is provided with anti-slip bumps. By setting the anti-slip bumps, the friction force in contact with the cloth bag rings 21 is further improved, thereby further ensuring the stability of the positioning of the cloth bag rings 21 at both ends.

[0030] Furthermore, limiting balls are provided at both ends of the tightening rope 22, and the length of the tightening rope 22 is greater than the diameter of the bag ring 21. The setting of the limiting balls can prevent the ends of the tightening rope 22 from being pulled and hidden inside the bag ring 21, thereby ensuring the convenience of using the tightening rope 22.

[0031] Working principle: The smoke pipe main body 1 and the dust bag 2 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is in use, the dust bag 2 is first sleeved on the outside of the smoke pipe main body 1, first tightened by the tightening ropes 22 at both ends, and tied to the inside of the corresponding positioning ring 3, and then the tightening ropes 22 inside are further tightened to ensure the fit between the dust bag 2 and the smoke pipe main body 1, and finally the pipeline is installed and positioned through the connecting pipes 11 at both ends before use.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
