Description

Technical Field

[0001] This utility model relates to the field of electrothermal alloy technology, specifically to an easy-to-install electrothermal alloy strip. Background Technology

[0002] Electrothermal alloy strips are thin strip-shaped electrothermal elements made from alloys such as iron-chromium-aluminum and nickel-chromium. They are the core heating components of various electric furnaces, kilns and other high-temperature heating equipment. With their excellent high-temperature oxidation resistance, stable resistivity and uniform heating performance, they have become a key material in the field of industrial heating. However, existing electrothermal alloy strips have problems with installation stability: they not only lack reliable fixing structures, but are also prone to falling off during use. Utility Model Content

[0003] The purpose of this invention is to provide an easily installable electrothermal alloy strip to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an easy-to-install electrothermal alloy strip, including a strip body, the strip body being arranged in a continuously bent S-shape, a fixing cylinder being welded to the bend of the strip body, and a ceramic cylinder for bolt threading being sleeved inside the fixing cylinder.

[0005] Furthermore, the top of the ceramic cylinder is integrally provided with a ceramic handle that covers and fixes the top of the cylinder, and the inner wall of the ceramic handle is in communication with the inner wall of the ceramic cylinder.

[0006] Furthermore, the outer wall of the ceramic cylinder is threadedly connected to the inner wall of the fixed cylinder.

[0007] Furthermore, the outer wall of the ceramic handle is provided with knurled grooves.

[0008] Furthermore, the cross-section of the belt is corrugated.

[0009] The beneficial effects achieved by this utility model are as follows: The belt body is welded with a fixed cylinder and equipped with a ceramic cylinder at the bend. The ceramic / metal bolts are connected to the pre-set threaded connection holes of the high-temperature heating equipment, which can be fixed point by point. The installation is highly flexible and effectively prevents it from falling off during use. At the same time, the material of the ceramic cylinder insulates the fixed cylinder and the metal bolt, preventing the current from flowing through the metal bolt and generating heat. In addition, the thermal conductivity of ceramic is much lower than that of metal, which effectively reduces the heat radiation of the belt body to the bolt.

[0010] The ceramic tube has an integral ceramic handle at the top, and the outer wall of the ceramic tube is threaded to the inner wall of the fixed tube. The ceramic handle allows for easy screwing and unscrewing of the ceramic tube, making maintenance more convenient.

[0011] The ceramic handle has knurled grooves on the outer wall to increase friction when turning, improve the feel of operation, and prevent slippage.

[0012] The cross-section of the belt is corrugated, which increases the heating area and thus improves the heating rate and heating efficiency. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1-2 As shown, this utility model discloses an easy-to-install electrothermal alloy strip, comprising: a flexible strip body 1, the strip body 1 being continuously bent in an S-shape, a fixing cylinder 2 welded to the bend of the strip body 1, and a ceramic cylinder 3 for bolt threading inside the fixing cylinder 2.

[0016] Based on the above structure, such as Figure 1-2 As shown, during installation, first connect the ceramic / metal bolt connection end to the ceramic cylinder 3 with a thread. Then, place the belt body 1 with bolts inside the high-temperature heating equipment. Align the ceramic cylinders 3 from one end of the belt body 1 to the other end with the threaded connection holes (which are pre-drilled) at the corresponding installation positions inside the high-temperature heating equipment. When each ceramic cylinder 3 is aligned with a threaded connection hole, rotate the bolt inside the ceramic cylinder 3 to screw the bolt into the threaded connection hole until it is secure.

[0017] Furthermore, such as Figure 1-2 As shown, in order to facilitate the replacement of the ceramic cylinder, the top of the ceramic cylinder 3 is integrally provided with a ceramic handle 31 that covers the top of the fixed cylinder 2, and the inner wall of the ceramic handle 31 is connected to the inner wall of the ceramic cylinder 3.

[0018] Furthermore, such as Figure 2 As shown, to further facilitate the replacement of the ceramic cylinder, the outer wall of the ceramic cylinder 3 is threadedly connected to the inner wall of the fixed cylinder 2.

[0019] Furthermore, in order to increase the friction when screwing the ceramic handle, the outer wall of the ceramic handle 31 is provided with knurled grooves.

[0020] Furthermore, such as Figure 3 As shown, in order to increase the heating rate of the belt, the cross section of the belt 1 is corrugated, and the corrugated design can increase the heating area of ​​the belt.
