Description

Technical Field

[0001] The utility model relates to the technical field of anti-wear structures for finned tubes, and specifically provides an anti-wear structure for finned tubes. Background Art

[0002] Finned tubes usually increase the surface area by winding fins on the base tube. The main function of finned tubes is to improve the heat transfer efficiency by increasing the surface area of the heat transfer element. These fins can be made of different materials, such as copper-aluminum, stainless steel, etc., to adapt to different working environments and temperature requirements. Finned tubes are widely used in various industrial fields.

[0003] The existing patent CN206094018U, an anti-wear device for an H-type finned tube economizer, realizes the positioning of the anti-wear main body and the base tube by corresponding the two and dropping the anti-wear main body, so that the fins pass through the through holes. The assembly is convenient. By using the utility model, the original heat transfer area can be guaranteed, and the wear resistance and corrosion resistance of the H-type finned tube can be effectively enhanced without removing the fins of the first row of base tubes.

[0004] In the existing device, the fins will be deformed to a certain extent during the installation and use process. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-wear structure for finned tubes to solve the problem that the fins will be deformed to a certain extent during the installation and use process in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an anti-wear structure for finned tubes, on the top of the anti-wear main body, there are multiple groups of first wedge-shaped plates and second wedges. The angles of the first wedge-shaped plates and the second wedges are set in an inclined state. Because the angles of the first wedge-shaped plates and the second wedges are inclined, a triangular structure is formed by the first wedge-shaped plates, the second wedges, and the fins.

[0007] Preferably, multiple groups of first grooves are arranged on the top of the anti-wear main body. The first grooves are arranged at the positions between the first wedge-shaped plates and the second wedges, so that the first wedge-shaped plates and the second wedges can hold the fins against.

[0008] Preferably, multiple groups of fins are arranged inside the first grooves. The first grooves in the anti-wear main body are aligned with the fins, and the tops of the first wedge-shaped plates and the second wedges are in contact with the outer sides of the fins.

[0009] Preferably, multiple groups of cushion blocks are arranged at the bottom of the anti-wear main body to prevent damage to the base tube when the anti-wear main body is deformed. The cushion blocks are arranged at one end of the first grooves.

[0010] Preferably, a base pipe is provided at the bottom of the cushion block, and there is a certain gap between the anti-wear main body and the base pipe, and the outside of the base pipe is connected to the fins.

[0011] Preferably, two round holes are provided at one end of the anti-wear main body.

[0012] Preferably, a support rod is provided inside the round hole. By installing the support rod in the round hole, it is more difficult for the top of the anti-wear main body to deform, and the support rod is used to reinforce the strength of the top of the anti-wear main body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing the first wedge plate and the second wedge, the first wedge plate and the second wedge hold the fins. Since the angles of the first wedge plate and the second wedge are inclined, a triangular structure is formed by the first wedge plate, the second wedge, and the fins, preventing the fins from deforming during installation and use.

[0015] 2. By providing the cushion block, there is a certain gap between the anti-wear main body and the base pipe, preventing damage to the base pipe when the anti-wear main body deforms. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] An anti-wear structure for a finned tube, as Figure 1 、2 As shown in Figures 3, it includes an anti-wear main body 2. Multiple groups of first wedge plates 3 and second wedge plates 301 are arranged at the top of the anti-wear main body 2. The angles of the first wedge plates 3 and the second wedge plates 301 are inclined. Since the angles of the first wedge plates 3 and the second wedge plates 301 are inclined, the first wedge plates 3, the second wedge plates 301, and the fins 101 form a triangular structure. Multiple groups of first grooves 201 are arranged at the top of the anti-wear main body 2. The first grooves 201 are arranged at the positions between the first wedge plates 3 and the second wedge plates 301, so that the first wedge plates 3 and the second wedge plates 301 hold the fins 101. Multiple groups of fins 101 are arranged inside the first grooves 201. The first grooves 201 in the anti-wear main body 2 are aligned with the fins 101. The tops of the first wedge plates 3 and the second wedge plates 301 are in contact with the outer sides of the fins 101.

[0023] It should be noted that by aligning the first grooves 201 in the anti-wear main body 2 with the fins 101, the first wedge plates 3 and the second wedge plates 301 hold the fins 101. Since the angles of the first wedge plates 3 and the second wedge plates 301 are inclined, the first wedge plates 3, the second wedge plates 301, and the fins 101 form a triangular structure, preventing the fins 101 from deforming during installation and use.

[0024] Please refer specifically to Figure 1 、 2 Figures 3 and 4. Multiple groups of cushion blocks 302 are arranged at the bottom of the anti-wear main body 2 to prevent damage to the base pipe 1 when the anti-wear main body 2 deforms. The cushion blocks 302 are arranged at one end of the first grooves 201. The base pipe 1 is arranged at the bottom of the cushion blocks 302. There is a certain gap between the anti-wear main body 2 and the base pipe 1. The outer side of the base pipe 1 is connected to the fins 101. Two round holes 202 are arranged at one end of the anti-wear main body 2. Support rods 303 are arranged inside the round holes 202. By installing the support rods in the round holes 202, it is more difficult for the top of the anti-wear main body 2 to deform. The support rods 303 are used to reinforce the strength of the top of the anti-wear main body 2.

[0025] It can be understood that by leaving a certain gap between the anti-wear main body 2 and the base pipe 1, damage to the base pipe 1 is prevented when the anti-wear main body 2 deforms. By installing the support rods in the round holes 202, it is more difficult for the top of the anti-wear main body 2 to deform.

[0026] Working principle: Spot-weld the fins 101 on the base pipe 1, and then place the anti-wear main body 2 on the top of the base pipe 1, align the first grooves 201 in the anti-wear main body 2 with the fins 101, so that the first wedge plates 3 and the second wedge plates 301 hold the fins 101. Since the angles of the first wedge plates 3 and the second wedge plates 301 are inclined, the first wedge plates 3, the second wedge plates 301, and the fins 101 form a triangular structure, preventing the fins 101 from deforming during installation and use;

[0027] Through the provided spacer block 302, a certain gap is left between the anti-wear main body 2 and the base pipe 1 to prevent damage to the base pipe 1 when the anti-wear main body 2 deforms. The support rod is installed in the round hole 202, making the top of the anti-wear main body 2 less likely to deform.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
