Description

Technical Field

[0001] This utility model relates to the field of electric heater technology, and more specifically, to an air heater with a support bracket. Background Technology

[0002] Existing air heaters use bolts and nuts to fix the temperature measuring tube, resulting in low connection strength and making it prone to slippage, rotation, or even detachment. This significantly reduces the effectiveness of temperature measurement or even renders the tube ineffective. This design uses a newly designed bracket to connect the heating element and the temperature measuring tube, preventing the measuring tube from contacting the heating element and ensuring the accuracy of the sensor inside the measuring tube. Therefore, this invention proposes an air heater with a bracket support. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an air heater with a support bracket. The air heater connects the temperature measuring tube and the heating tube through the temperature measuring tube bracket, thereby preventing any displacement or rotation of the temperature measuring tube.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is as follows: The air heater with a support bracket involved in this utility model includes a spiral-shaped heating tube body, a temperature measuring tube bracket on the heating tube body, and a temperature measuring tube on the temperature measuring tube bracket.

[0005] The present invention is further configured such that: the temperature measuring tube support includes an inner support plate and an outer support plate, and at least one hole is formed between the outer support plate and the inner support plate for the heating tube body to pass through, the heating tube body is installed in the hole, and the temperature measuring tube is disposed on the inner support plate.

[0006] The present invention is further configured such that: the inner plate of the bracket is composed of a longitudinal inner plate extending along the axial direction of the heating tube body and a transverse inner plate extending along the radial direction of the heating tube body; the outer plate of the bracket is connected to the longitudinal inner plate; and the temperature measuring tube is connected to the transverse inner plate.

[0007] The present invention is further configured such that: the outer plate of the bracket and the inner plate of the longitudinal direction are fixed by welding; and the temperature measuring tube and the inner plate of the transverse direction are fixed by riveting.

[0008] The present invention is further configured such that the holes are arranged at intervals along the axial direction of the heating tube body.

[0009] The present invention is further configured such that the number of holes is three in a row.

[0010] The present invention is further configured such that the temperature measuring tube support is arranged in a ring array around the axis of the heating tube body.

[0011] The present invention is further configured such that: the number of temperature measuring tube supports is not less than two; and the included angle between two adjacent temperature measuring tube supports is equal.

[0012] The present invention is further configured such that the temperature measuring tube support is located on the inner side of the heating tube body.

[0013] The present invention is further configured such that the temperature measuring tube support is located on the outside of the heating tube body.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. It effectively prevents problems such as sliding, turning and displacement of the overall temperature measuring device caused by external environmental factors, so that the entire temperature measuring device can accurately measure the temperature.

[0016] 2. Since the connection method is spot welding on the outside of the heating tube, installation on the inside of the heating tube can be avoided, which greatly increases the operability in terms of installation space, facilitates personnel operation, optimizes the overall operation difficulty, and saves the overall operation time.

However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0022] Example 1

[0023] See Figures 1 to 3 As shown, the air heater with a support bracket involved in this embodiment includes a spiral-shaped heating tube body 1, a temperature measuring tube bracket 2 on the heating tube body 1, and a temperature measuring tube 3 on the temperature measuring tube bracket 2.

[0024] Furthermore, the temperature measuring tube support 2 includes an inner support piece 21 and an outer support piece 22. Three holes 23 are formed between the outer support piece 22 and the inner support piece 21 for the heating tube body to pass through. The heating tube body 1 is installed in the holes 23, and the temperature measuring tube 3 is disposed on the inner support piece 21.

[0025] Furthermore, the inner plate 21 of the support is composed of a longitudinal inner plate 211 extending along the axial direction of the heating tube body and a transverse inner plate 212 extending along the radial direction of the heating tube body. The outer plate 22 of the support is connected to the longitudinal inner plate 211, and the temperature measuring tube 3 is connected to the transverse inner plate 212.

[0026] Furthermore, the outer piece 22 of the bracket is fixed to the inner piece 211 by welding; the temperature measuring tube 3 is fixed to the inner piece 212 by riveting.

[0027] Furthermore, the holes 23 are arranged at intervals along the axial direction of the heating tube body 1.

[0028] Furthermore, the number of holes 23 is three in a row.

[0029] In this embodiment, the three holes 23 formed between the outer piece 22 and the inner piece 21 of the bracket are used for the heating tube body 1 to pass through, so that the temperature measuring tube bracket 2 can be fixed on the heating tube body 1, and the temperature measuring tube 3 is fixed on the temperature measuring tube bracket 2 without contacting the heating tube body 1.

[0030] Example 2

[0031] See Figures 1 to 3 As shown, the air heater with a support bracket involved in this embodiment is further configured, based on embodiment 1, such that the temperature measuring tube bracket 2 is arranged in a ring array around the axis of the heating tube body 1.

[0034] See Figures 1 to 3 As shown, the air heater with a support bracket involved in this embodiment is further configured, based on embodiment 1, that the temperature measuring tube bracket 2 is located on the inner or outer side of the heating tube body 1.

[0035] In this embodiment, by placing the temperature measuring tube bracket 2 inside the heating tube body 1, it can be ensured that the temperature measuring tube 3 can accurately measure the temperature without being exposed to the outside.

[0036] By placing the temperature measuring tube bracket 2 on the outside of the heating tube body 1, installation and maintenance can be facilitated.

[0037] The air heater with bracket support involved in this utility model effectively prevents the overall temperature measuring device from slipping, turning and shifting due to external environmental factors, so that the entire temperature measuring device can accurately measure the temperature; and because the connection method is spot welding on the outside of the heating tube, it can avoid installation on the inside of the heating tube, which greatly increases the operability in terms of installation space, facilitates the operation of personnel, optimizes the overall operation difficulty, saves the overall operation time, and has complete functions and strong practicality.
