Problems solved by technology

However, if the working environment of the fan is not hygienic, after a period of use, thick dust and oil will easily accumulate on the fan blades. If it is not treated in time, a large amount of dirt will make the fan blades run unbalanced, increase vibration, and cause bearing damage.
In special weather conditions, if the fan is still running and it is not in a sheltered place, it is easy to cause corrosion of the fan to varying degrees and cause damage to the fan

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as Figure 1 to Figure 3 As shown, the anti-fouling blower in this embodiment includes a frame 1 , a stator assembly 3 and a rotor assembly 2 arranged in the frame 1 , and fan blades 5 uniformly installed on the frame 1 . In order to stabilize the internal components of the machine base 1 , an end cover 4 with a sheet structure is installed at one end of the machine base 1 .

[0016] Wherein, the base 1 is configured as a cylindrical structure with a hollow cavity inside, and a bearing 11 is installed in the middle of the base 1 and a corresponding rotor assembly 2 and a stator assembly 3 are installed. The rotor assembly 2 includes a rotor core 21 and a rotating shaft 22 . Specifically, the rotor core 21 is made of silicon steel and is arranged on the inner wall of the frame 1 . The rotating shaft 22 is installed on the bearing ...

Abstract

An anti-stain draught fan comprises a fan base, a stator assembly, a rotor assembly and blades arranged on the fan base, wherein the stator assembly and the rotor assembly are arranged in the fan base. A bearing is installed in the fan base. One end of the fan base is provided with an end cover. The rotor assembly comprises a rotor iron core arranged on the inner side wall of the fan base and a rotating shaft installed on the bearing. The stator assembly comprises a stator iron core arranged in the rotor iron core in a sleeved manner and a stator winding wound around the stator iron core. According to the anti-stain draught fan, by spraying special solution to the blades of the draught fan, the rotor iron core and an end cover, the anti-stain capacity of the draught fan can reach the degree that the draught fan is free of rusting for 244 hours in a salt spray test, and in a normal temperature work environment, ordinary stain is prevented from being attached to the draught fan. Comparedwith the prior art, the anti-stain draught fan does not need frequent clearing, the draught fan is protected from being corroded by accumulated stain, the normal work function of the draught fan is guaranteed, and the maintenance cost in a later period is saved.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an anti-stain fan. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. During work, the fan blades rotate to drive the gas flow, thereby realizing the gas discharge. However, if the working environment of the fan is not hygienic, thick dust and oil will easily accumulate on the fan blades after a period of use. If not dealt with in time, a large amount of dirt will make the fan blades run unbalanced, increase vibration, and cause bearing damage. In special weather conditions, if the fan is still running and it is not in a sheltered place, it is easy to cause corrosion of the fan to varying degrees and cause damage to the fan. Therefore, be badly in need of a kind of fan that can prevent general stain from adhering. Contents of the invention [0003] The te...
