Problems solved by technology

Because it is hand-polished, the quality of the polishing cannot be controlled
At the same time, the amount of dust generated by grinding is huge, which pollutes the environment and poses great harm to the operating staff
[0004] Sand blasting has been used in the mechanical industry, but due to the huge size of fan blades, it has not been applied to the surface treatment of composite fan blades, and the design of sand blasting system and the selection of sand blasting raw materials are difficult, which limits its application

Abstract

The invention discloses a sand blasting device for a wind blade surface and a sand blasting method thereof. The sand blasting device comprises two symmetric sand blasting mechanisms (1), a de-dusting mechanism (2), a sand recycling mechanism (3) and blade traveling mechanisms, wherein the de-dusting mechanism (2) is arranged between the two symmetrical sand blasting mechanisms (1); the sand recycling mechanism (3) is arranged at the bottom of a middle area of the two symmetrical sand blasting mechanisms (1); the blade traveling mechanisms are arranged on the two sides of the sand recycling mechanism (3). The sand blasting device has the advantages of reasonable structure design, convenience in operation, low cost, excellent sand blasting effect, no damage to fan blades, capability of greatly increasing the processing efficiency and greatly saving manpower, less environmental pollution and wide application in sand blasting for the large-size wind blade surface. The sand blasting method for the wind blade surface provided by the invention has the advantages of reasonable technical design, high maneuverability, high working efficiency, low cost, high quality of the wind blade surface subjected to sand blasting and capability of increasing the overall performance of the wind blade.

Description

technical field [0001] The invention relates to the field of manufacturing wind power blades, in particular to a sandblasting treatment device and a sandblasting treatment method for the surface of wind power blades. Background technique [0002] With the gradual depletion of non-renewable energy on the earth, the whole world has realized the importance of renewable energy and has begun to attach great importance to the development of the wind power industry. As the most important part of a wind turbine, the blade plays an irreplaceable role in the wind turbine. A wind turbine blade with excellent design, reliable quality and high-efficiency performance is a key factor to ensure the normal operation of the entire wind turbine. [0003] Reasonable grinding and cleaning of wind power blades can effectively improve the surface quality of the blades and provide a basis for the subsequent painting process. What is used in the industry now is to manually use a pneumatic grinder t...
