Description

Technical Field

[0001] This utility model relates to the technical field of demister components, specifically to demister fixing tubes. Background Technology

[0002] Existing technical solutions for roof demister blade fixation use either a solid through-tube rod with bolts on both sides or welding. Welding requires individual welding, which is unsightly and prevents individual blade replacement later. While bolt and nut connections allow for individual blade replacement, they have drawbacks: the solid through-tube rod requires more material, and bolts and nuts on both sides require additional fabrication and tightening processes. Furthermore, there is a risk of bolts and nuts loosening and falling off during transportation and use.

[0003] Therefore, it is necessary to design a fixed pipe for the demister. Utility Model Content

[0004] The purpose of this invention is to provide a fixed pipe for a demister, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] The demister fixing tube includes a tube, a deformable end, and a positioning pin. Both ends of the tube are fitted with deformable ends, the outer diameter of which is the same as the outer diameter of the tube. The tail end of the deformable end has a through hole, and the positioning pin passes through the tube and combines with the through hole.

[0007] According to the above technical solution, the deformable end includes an insert cylinder seat and a deformable cage. The deformable cage is integrally formed on the head of the insert cylinder seat. An inner nut is fixedly installed in the middle of the cylinder of the insert cylinder seat. A positioning bolt is screwed into the inner nut. The outer end nut of the positioning bolt is combined with the head of the deformable cage for limiting.

[0008] According to the above technical solution, the deformation radius of the deformable cage is 1.1 to 1.2 times the radius of the tube.

[0009] According to the above technical solution, the head end of the deformable cage is integrally formed, and the diameter of the through hole in the middle is larger than the outer diameter of the positioning bolt.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] By replacing solid rods with hollow tubes, sufficient strength is ensured while using less material and reducing weight. This saves a lot of money and reduces the weight of the demister, especially for metal materials where weight per unit price is critical. In addition, the hollow tubes achieve non-stress deformation and self-limitation through the material properties of the deformation end, thus preventing blades from falling off. This allows for individual blade replacement after simple cleaning. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Please see Figure 1-3 The present invention provides a technical solution: a demister fixing tube, including a tube 1, a deformable end 2 and a positioning pin 3. Both ends of the tube 1 are fitted with deformable ends 2. The outer diameter of the deformable end 2 is the same as the outer diameter of the tube 1. The tail end of the deformable end 2 is provided with a through hole. The positioning pin 3 passes through the tube 1 and is combined with the through hole.

[0020] The through-tube 1 is the main bearing structure of the blade, and the deformation end 2 is the main connector for deformation. The positioning pin 3, together with the through hole, effectively positions the deformation end 2, avoiding circumferential and axial movement, so that the device can operate at the specified temperature.

[0021] Specifically, the deformable end 2 includes an insert cylinder seat 201 and a deformable cage 202. The deformable cage 202 is integrally formed on the head of the insert cylinder seat 201. An inner nut 204 is fixedly installed in the middle of the cylinder of the insert cylinder seat 201. A positioning bolt 203 is screwed onto the inner nut 204. The outer end nut of the positioning bolt 203 is combined with the head of the deformable cage 202 for limiting.

[0022] The mounting base 201 is made of non-memory metal casting, and the deformation cage 202 is made of iron-based memory metal and integrally formed with the mounting base 201, so as to restore the deformation state under high temperature. The inner nut 204 is the anchoring structure of the positioning bolt 203. The positioning bolt 203 positions the deformation cage 202 after deformation through its own nut, so as to prevent it from returning to a flat state after cooling.

[0023] Specifically, the deformation radius of the deformable cage 202 is 1.1 to 1.2 times the radius of the tube 1.

[0024] By setting the radius after deformation of the deformable cage 202, an effective limiting effect is ensured, avoiding the reduction of the limiting effect caused by the allowance left by the blade for easy installation.

[0025] Specifically, the head end of the deformable cage 202 is integrally formed, and the diameter of the through hole in the middle is larger than the outer diameter of the positioning bolt 203.

[0026] The integral molding of the head end ensures the integrity of the structure during deformation, while preventing deformation from affecting the operation of the positioning bolt 203.

[0027] Working principle: During use, the deformable end 2 at one end is heated to deform the deformable cage 202. Then, the positioning bolt 203 moves to achieve position limitation. When the temperature drops, it still maintains the deformed state and keeps the screw in a compressed state. Then, the blade is installed through the other end. After installation, the deformable end 2 at the other end is heated to deform it. Then, the positioning bolt 203 moves to achieve the limitation behind the deformable end 2.

[0028] For subsequent maintenance and replacement, heating one of the deformed ends 2 will loosen and remove the positioning bolts 203. After cooling, the structure of the deformed end 2 can be restored. After replacing the blade, the initial installation steps can be repeated.
