Abstract

The invention relates to an efficient polyurethane defoaming device and defoaming method. The efficient polyurethane defoaming device comprises a shell, a rotatable defoaming assembly is arranged in the shell and comprises partition plates, the partition plates comprise an upper partition plate and a lower partition plate, materials sequentially flow through the upper partition plate and the lower partition plate from top to bottom, and film thickness control parts are arranged on the partition plates. Each film thickness control part comprises a control plate fixed above the partition plates, and a channel for materials to flow through is arranged between the control plates and the partition plates. The defoaming device is short in defoaming time, good in resin uniformity, good in defoaming effect and high in defoaming efficiency.

Description

technical field [0001] The invention belongs to the technical field of wind power blades, and in particular relates to a polyurethane high-efficiency defoaming device and a defoaming method. Background technique [0002] Wind power generation is an important development direction of the country's new energy industry in recent years. Through wind power generation equipment, the natural wind energy is converted into electrical energy, realizing the development and utilization of clean energy in the country. The main components of wind power generation equipment are: blades (wind rotors), generator sets (including devices), yaw systems, brakes, speed limits, towers, control safety mechanisms, and energy storage devices. [0003] Among them, the quality of fan blades has a major impact on the power generation system. At present, the mainstream material of fan blades on the market has been converted from epoxy resin to polyurethane. An important factor that determines the quality...
