Description

[Technical Field]

[0001] This utility model relates to the field of heating tube technology, and in particular to wear-resistant and high-temperature resistant heating tubes. [Background Technology]

[0002] A heating element is a device used to convert electrical energy into heat energy. It typically consists of a metal tube, a resistance wire, insulating material, and terminals. Its working principle is that the resistance wire generates heat when energized, transferring the heat to the metal tube, which then transfers the heat to the surrounding environment or medium. Some heating elements have numerous fins on their surface to increase heat transfer efficiency, thereby increasing the contact area with the material. However, this results in difficulties in cleaning the spaces between the fins; various dirt and material residues easily accumulate in the gaps between the fins, affecting heat transfer efficiency and potentially causing material contamination. [Utility Model Content]

[0003] The purpose of this invention is to solve the problems in the prior art and to propose a wear-resistant and high-temperature resistant heating tube that is easy to clean.

[0004] To achieve the above objectives, this utility model proposes a wear-resistant and high-temperature resistant heating tube, including a heating tube body and a mounting base disposed at the end of the heating tube body. The mounting base is provided with a power connection position, and the surface of the heating tube body is provided with a plurality of heat transfer fins.

[0005] The heating tube body is also provided with a scraping mechanism, which includes a support system and several scrapers. The support system is sleeved on the heating tube body and rotatably connected to the heating tube body. The support system is provided with several scrapers facing the heating tube body, and the scrapers extend into the gaps between the heat transfer fins.

[0006] Preferably, the support system includes a first rotating connecting ring and a second rotating connecting ring respectively disposed at both ends of the heating tube body, and at least two connecting arms arranged along the axial direction of the heating tube body are provided between the first rotating connecting ring and the second rotating connecting ring, and the scraper is fixed on each of the connecting arms respectively.

[0007] Preferably, the surface of the heating tube body is provided with an enamel layer.

[0008] Preferably, the surface of the heat transfer fins is also provided with the enamel layer.

[0009] Preferably, the first rotating connecting ring and / or the second rotating connecting ring are provided with a plurality of spring pins facing the heating tube body, and the outer wall of the heating tube body is provided with a plurality of positioning grooves for cooperating with the spring pins.

[0010] Preferably, the scraper is inclined.

[0011] The beneficial effects of this wear-resistant and high-temperature resistant heating tube are as follows: By setting heat transfer fins on the surface of the heating tube body, the heat dissipation area of ​​the heating tube body can be increased, thereby improving heat transfer efficiency and heating speed. The scraping mechanism can solve the problem of material residue inside the gap between the scrapers, making it convenient to clean the heating tube body and heat transfer fins, avoiding affecting the heating efficiency of the heating tube body, and also preventing contamination of the heating tube body due to uncleanliness. The enamel layer on the surface of the heating tube body is used to protect the heating tube, ensuring that the metal material is not oxidized and corroded, improving strength, high temperature resistance, and wear resistance. Moreover, the scraping mechanism is set outside the heating tube body, which can also play a certain protective role for the heating tube body, improving the wear resistance and impact resistance of the heating tube body.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. [Attached Image Description]

[0023] Example 1:

[0024] See Figures 1-5 This utility model discloses a wear-resistant and high-temperature resistant heating tube, comprising a heating tube body 1 and a mounting base 2 disposed at the end of the heating tube body 1. A power connection position 3 is provided on the mounting base 2. The surface of the heating tube body 1 is provided with a plurality of heat transfer fins 11. By setting the heat transfer fins 11, the heat dissipation area of ​​the heating tube body 1 can be increased, thereby improving heat transfer efficiency and heating speed.

[0025] See Figure 1 , Figure 3 , Figure 4 and Figure 5 The heating tube body 1 is also equipped with a scraping mechanism, which includes a support system 4 and several scrapers 5. The support system 4 is sleeved on the outside of the heating tube body 1 and rotatably connected to the heating tube body 1. The support system 4 is provided with several scrapers 5 facing the heating tube body 1, and the scrapers 5 extend into the gaps between the heat transfer fins 11. By setting up the scraping mechanism, the problem of material residue inside the gaps between the scrapers 5 can be solved, which facilitates cleaning of the heating tube body 1 and the heat transfer fins 11, avoids affecting the heating efficiency of the heating tube body 1, and also avoids contamination of the heating tube body 1 by dirt. In addition, the scraping mechanism is set on the outside of the heating tube body 1, which can also play a certain protective role for the heating tube body 1 and improve the wear resistance and impact resistance of the heating tube body.

[0026] See Figure 3 , Figure 4 The support system 4 includes a first rotating connecting ring 41 and a second rotating connecting ring 42 respectively located at both ends of the heating tube body 1. Two connecting arms 43 are provided between the first rotating connecting ring 41 and the second rotating connecting ring 42, arranged axially along the heating tube body 1. The scraper 5 is fixed to each of the connecting arms 43. The first rotating connecting ring 41 and the second rotating connecting ring 42 enable a rotatable connection with the heating tube body 1, while the connecting arms 43 fix the scraper 5 in place.

[0027] Example 2:

[0028] Preferably, based on Embodiment 1, both the surface of the heating tube body 1 and the surface of the heat transfer fins 11 are provided with an enamel layer. The enamel layer is used to protect the heating tube, ensure that the metal material is not oxidized and corroded, improve strength, and enhance high-temperature resistance and wear resistance.

[0029] See Figure 2 , Figure 4 , Figure 5 The first rotating connecting ring 41 and the second rotating connecting ring 42 are provided with several spring pins 44 facing the heating tube body 1. The outer wall of the heating tube body 1 is provided with several positioning grooves 12 for cooperating with the spring pins 44. The spring pins 44 are used to cooperate with the positioning grooves 12 to position and fix the angle after the support system 4 is used, so that the support system 4 is more stable in the daily state.

[0030] Preferably, the scraper 5 is inclined. The scraper 5 has a certain angle, which makes the scraping effect better.

[0031] The working process of this utility model:

[0032] In operation, the wear-resistant and high-temperature heating tube of this utility model heats the material through the heating tube body 1. When it is necessary to clean the residual material between the heating tube body 1 and the heat transfer fins 11, the support system 4 can be rotated. The support system 4 drives the scraper 5 of the support system 4 to scrape between the heat transfer fins 11, thereby removing the residual material and stains.
