Technical Field

[0001] The present application relates to the technical field of fan rotors, and in particular to a high-temperature resistant fan rotor. Background Art

[0002] At present, in response to the environmental protection requirements of energy conservation and emission reduction, some steel companies have taken innovative measures to use fans to recover the hot flue gas originally discharged, and reintroduce it into the sintering furnace for recycling to heat the ore.

Under long-term action, the fan impeller is easily eroded by high-temperature smoke and dust, resulting in increased wear and shortened service life. This requires frequent replacement of the impeller, which not only increases production costs, but also goes against the original intention of energy conservation and emission reduction, and greatly reduces the environmental benefits.

[0004] In view of the above problems, a high temperature resistant fan rotor is now designed. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] The embodiments of the present application provide a high-temperature resistant fan rotor, which can solve the problem in the related art that the fan impeller is eroded by high-temperature smoke for a long time, which easily leads to increased wear and shortened service life.

[0027] See also Figure 1-Figure 4 , a high-temperature resistant fan rotor, which includes: a main shaft 1, a wheel disc 2, a wheel cover 3, blades 4, a sleeve 5 and a fixing ring 6, the wheel disc 2 is sleeved on the main shaft 1, the wheel cover 3 is sleeved on the main shaft 1, the wheel cover 3 is located on one side of the wheel disc 2, the blades 4 are provided in a plurality of groups, and the plurality of blades 4 are provided between the wheel disc 2 and the wheel cover 3, and the plurality of blades 4 are evenly distributed on the wheel disc 2 in a ring shape with the axis of the main shaft 1 as the axis, the blades 4 are fixedly connected to the wheel disc 2 and the wheel cover 3, the sleeve 5 is provided in a plurality of groups, and the plurality of sleeves 5 are sleeved on the blades 4, the sleeve 5 is located on the side of the blade 4 away from the main shaft 1, and the fixing ring 6 is provided on the side of the wheel disc 2 away from the wheel cover 3;

[0028] In this way, the blades 4 can be shielded and protected by the sheath 5 to prevent the blades 4 from being eroded by high-temperature smoke and dust, thereby increasing the service life of the blades 4. At the same time, the overall structural strength of the blades 4 can be further enhanced to prevent the blades 4 from being deformed and affecting the use effect when running in a high-temperature environment for a long time. Since the side of the wheel disc 2 away from the wheel cover 3 is also easily eroded by high-temperature smoke and dust, the wheel disc 2 can be shielded and protected by the fixing ring 6 to increase the service life of the wheel disc 2, thereby further increasing the service life of the fan and ensuring the durability and stability of the fan rotor in a high-temperature and high-dust environment. In this way, there is no need to frequently replace the fan impeller during use, which can reduce production costs, save energy, protect the environment, and has strong practicality.

[0029] Specifically, in this embodiment, a guard plate 7 is provided at one end of the sheath 5 close to the wheel disc 2, and the guard plate 7 is connected to the wheel disc 2;

[0030] In this way, the guard plate 7 can form an additional protective barrier at the root of the blade 4 to prevent high-temperature smoke and dust from directly impacting the root of the blade 4, thereby ensuring the structural strength and stability of the blade 4 and extending the service life of the blade 4.

[0031] The edges and corners of the guard plate 7 are rounded;

[0032] This can reduce stress concentration and improve the fatigue resistance of the guard plate 7. At the same time, the rounded corners of the guard plate 7 can be achieved through precision machining or grinding technology to ensure that its edges are smooth and burr-free.

[0033] Furthermore, in this embodiment, mounting holes are provided on the wheel disc 2, blades 4, sheath 5, fixing ring 6 and guard plate 7. The sheath 5 is detachably connected to the blades 4 by screws, and the fixing ring 6 and guard plate 7 are detachably connected to the wheel disc 2 by screws.

[0034] In this way, during use, when the sheath 5, the guard plate 7 and the fixing ring 6 are worn after long-term use, the staff can use screws to disassemble and replace the damaged parts separately. This not only ensures the service life of the fan, but also when the protective parts at a certain position of the impeller are damaged, only the single part needs to be replaced, and there is no need to replace the entire impeller, which can reduce maintenance costs and is more environmentally friendly.

[0035] Furthermore, the surfaces of the sheath 5, the fixing ring 6 and the guard plate 7 are provided with a plurality of reinforcing ribs 8;

[0036] This can improve the structural strength and rigidity of these parts, reduce deformation caused by centrifugal force during high-speed rotation, and further enhance the protection of the impeller, thereby ensuring the service life of the fan.

[0037] Preferably, two sets of heat dissipation wheels 9 are sleeved on the main shaft 1, and the two sets of heat dissipation wheels 9 are respectively located at the two ends of the main shaft 1;

[0038] In this way, the two sets of heat dissipation wheels 9 can help the main shaft 1 dissipate heat and reduce its temperature rise in a high temperature environment. The heat dissipation wheels 9 can be made of materials with good thermal conductivity, such as copper or aluminum, to improve their heat dissipation efficiency.
