Description

Technical Field

[0001] This utility model belongs to the field of heating rack technology, and in particular relates to a heating rack with a heat insulation and protection structure. Background Technology

[0002] Traditional heating structures in industrial hot air equipment have significant safety defects: the surfaces of high-temperature components lack effective heat insulation, posing a serious risk of burns; forced air cooling cannot eliminate local heat accumulation, and long-term operation can easily lead to material aging or even fire risks; at the same time, conventional heat dissipation solutions cannot balance efficient heat exchange with equipment compactness, as adding insulation layers can hinder heat output, while external cooling systems significantly increase space occupation and energy consumption costs; more seriously, there is a lack of rapid pressure relief mechanisms in the event of sudden overheating, posing a risk of pressure vessel rupture; this results in serious deficiencies in equipment safety and reliability in high-temperature operating scenarios, restricting the stability of production processes.

[0003] To address these issues, we provide a heating element with a heat-insulating and protective structure. Utility Model Content

External air enters the outer sleeve from the air inlet pipe and is heated by the heating component inside the outer sleeve. The heated air is discharged from the air outlet pipe at one end of the outer sleeve. At the same time, the outer sleeve physically isolates the heating component, thus providing a protective effect. By installing a water storage sleeve on the outside of the outer sleeve and adding cooling water to the water storage sleeve, the cooling water cools the outer sleeve, thereby preventing the outer sleeve from being heated by the heating component and easily scalding people.

Detailed Implementation

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 4This utility model is a heating rack with a heat insulation and protection structure, including an outer casing assembly 1, a heating assembly 2, and a water cooling assembly 3. The outer casing assembly 1 includes an air inlet 101 and an outer casing 102. The water cooling assembly 3 includes a water storage sleeve 301 and a sleeve cover 302. By covering the opening end of the outer casing 102 with the cover 101a of one end of the air inlet 101, the heating assembly 2 is placed inside the outer casing 102. External air enters the outer casing 102 from the air inlet 101 and is heated by the heating assembly 2 in the outer casing 102. The heated air is discharged from the air outlet 102a at one end of the outer casing 102. At the same time, the outer casing 102 physically isolates the heating assembly 2, thus providing a protective effect. By sleeved with the water storage sleeve 301 on the outside of the outer casing 102 and adding cooling water to the water storage sleeve 301, the cooling water cools the outer casing 102, thereby preventing the outer casing 102 from being heated by the heating assembly 2 and easily causing burns to personnel.

[0027] Specifically, a pipe cover 101a is fixedly provided on one end face of the air inlet 101. The pipe cover 101a covers the open end of the outer sleeve 102. The closed end face of the outer sleeve 102 away from the pipe cover 101a is connected to the air outlet 102a. The heating component 2 is disposed inside the outer sleeve 102. The closed end face of the water storage sleeve 301 is connected to the sleeve port 301a. The sleeve port 301a is fixedly sleeved on the outside of the air outlet 102a. The sleeve cover 302 is sleeved through and sleeved on the outside of the air inlet 101. The sleeve cover 302 covers the open end of the water storage sleeve 301.

[0028] Furthermore, a set of pressure relief pipes 302a is connected to the end face of the sleeve cover 302 away from the water storage sleeve 301. A pipe end cap 302a-1 is fixedly covered on the end face of the pressure relief pipe 302a away from the sleeve cover 302. A vent hole is provided through the pipe end cap 302a-1. A pressure relief piston 302a-2 is slidably connected inside the pressure relief pipe 302a. A compression spring 302a-3 is sleeved inside the pressure relief pipe 302a. The two ends of the compression spring 302a-3 are respectively fixedly connected to... When the heating assembly 2 heats the outer sleeve 102, causing the outer sleeve 102 to transfer heat to the water storage sleeve 301, the cooling water in the water storage sleeve 301 heats up and evaporates a portion, thereby increasing the pressure in the water storage sleeve 301. The air pressure in the water storage sleeve 301 pushes the pressure relief piston 302a-2 to squeeze the compression spring 302a-3, thereby reducing the air pressure in the water storage sleeve 301.

[0029] Furthermore, a set of heat dissipation fins 302a-4 are fixedly arranged in a circumferential array on the outer sidewall of the pressure relief pipe 302a. The heat dissipation fins 302a-4 cool down the air entering the pressure relief pipe 302a, thereby reducing the air temperature and lowering the air pressure in the water storage sleeve 301.

[0030] Furthermore, the outer fixing pipe of the water storage sleeve 301 is fitted with a heat insulation sleeve 301b to prevent the cooling water in the water storage sleeve 301 from scalding personnel.

[0031] The operation process in this embodiment is as follows:

[0032] External air enters the outer casing 102 through the air inlet 101 and is heated by the heating element 2 in the outer casing 102. The heated air is discharged from the air outlet 102a at one end of the outer casing 102. At the same time, the outer casing 102 physically isolates the heating element 2, providing a protective effect. While the heating element 2 heats the outer casing 102, the heat is transferred through the outer casing 102 to the water storage sleeve 301, heating the cooling water in the water storage sleeve 301. The cooling water in the water storage sleeve 301 heats up and evaporates a portion, thereby increasing the pressure in the water storage sleeve 301. The air pressure in the water storage sleeve 301 pushes the pressure relief piston 302a-2 to compress the compression spring 302a-3, thereby reducing the air pressure in the water storage sleeve 301.

[0033] Example 2

[0034] Please see Figures 1 to 5 Based on embodiment 1, the heating assembly 2 includes two diffuser plates 201 and two baffle ring plates 202. A set of heating wires 201a is fixedly connected between the two diffuser plates 201 and the two baffle ring plates 202. When external air enters the outer tube 102, it meets the diffuser plates 201, causing the air to diffuse along the diffuser plates 201 to the surrounding area. This allows the air to enter between the diffuser plates 201 and the baffle ring plates 202 and be heated by the heating wires 201a, thus ensuring that the air is fully heated in the outer tube 102.

[0035] Specifically, two baffle rings 202 are disposed inside the outer sleeve 102, one diffuser 201 is disposed between the two baffle rings 202, and the other diffuser 201 is disposed between the tube cover 101a and the baffle rings 202. A heating wire 201a is disposed between each diffuser 201 and the baffle ring 202. The heating wire 201a has a spring-like structure, and the two ends of each heating wire 201a are fixedly connected to the plate surfaces of the diffuser 201 and the baffle ring 202, respectively.

[0036] Furthermore, a connecting rod 201a-1 is provided inside the heating wire 201a, and the two ends of the connecting rod 201a-1 are respectively fixedly connected to the surface of the diffuser plate 201 and the baffle ring plate 202.

[0037] Furthermore, a sleeve 202a is fixedly provided on the outer side of the baffle ring 202, and the outer wall of the sleeve 202a is attached to the inner wall of the outer sleeve 102.

[0038] The operation process in this embodiment is as follows:

[0039] When external air enters the outer tube 102, it encounters the diffuser plate 201, causing the air to diffuse outwards along the diffuser plate 201. This allows the air to enter between the diffuser plate 201 and the baffle ring 202, and be heated by the heating wire 201a, thus ensuring that the air is fully heated in the outer tube 102.
