Problems solved by technology

The disadvantage of this method is that it needs to be sequenced, baked twice, the production cycle is long, the painting process is prone to environmental pollution, and the requirements for the protection of occupational diseases and environmental protection are relatively high, which will increase the cost of the enterprise.
[0003] As the surface treatment technology of the first-generation impeller, the above-mentioned first spray coating process once played a certain role in the protection of the impeller. However, with the changes in the market, environmental protection requirements and the development of surface coating technology, this spray The disadvantages of the plastic coating process are obvious
Although the surface treatment technology of the above-mentioned second Teflon baking paint process has a good effect in anti-pollution (non-stick oil), whether the exhaust gas emission in the processing and production process is up to standard, the investment in occupational disease protection and the maintenance cost in the later period are extremely high. High, and the raw material paint has flammable and explosive problems, etc. Therefore, the disadvantages are also obvious

Abstract

The invention provides a non-oil-sticking fan impeller. The non-oil-sticking fan impeller comprises an impeller, wherein the impeller is installed on an output shaft of a rotor motor; a motor shell is arranged at the outer side of the rotor motor; the motor shell is installed on a housing through a motor fixing plate; an air inlet is formed in the housing at one side of the rotor motor; an air guide plate is installed on the air inlet; an air outlet is formed in one side of the housing; a junction box is installed on the motor fixing plate at one side of the rotor motor; the rotor motor is connected to mains supply through the junction box; and a nanometre Teflon non-sticking layer is arranged at the outer side of the impeller. The non-oil-sticking fan impeller provided by the invention has non-sticking performance such as non-oil-sticking performance, has the advantages of being resistant to wear, corrosion and high temperature, and high in surface smoothness, hardness and smoothness, is capable of being used for a long time in a temperature range from minus 40 DEG C to 300 DEG C and effectively preventing the surface from sticking, and is convenient to clean, thus the value of the product is greatly increased and the service life of the product is greatly prolonged. The non-oil-sticking fan impeller provided by the invention can be widely applied to axial-flow fans and centrifugal fans.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an oil-free fan impeller. Background technique [0002] In the prior art, there are two methods for the surface treatment of the impeller of the range hood: the first is to spray the surface of the impeller, and its process flow is upper part-ultrasonic degreasing-cleaning-drying-transfer / Upper piece - electrostatic spraying - baking - lower piece. The disadvantages of this method are that it needs to be sequenced, baked twice, the production cycle is long, dust pollution is prone to occur in the processing process, and the requirements for the protection of occupational diseases and environmental protection are relatively high, which will increase the cost of the enterprise. The second is to apply Teflon baking paint to the surface of the impeller. Its technological process is upper part-ultrasonic degreasing-clean water washing-drying-transfer / upper part-painting-baking-lower pa...
