Problems solved by technology

However, when using this kind of coating to modify the fan blade, the hardness of the formed coating is low, and it is difficult to resist wind and sand blowing.
[0006] The existing method of using paint to form a protective coating on the fan blades for anti-icing of the fan blades has an unsatisfactory effect and does not meet the requirements for use

Embodiment 1

[0028] The material surface modification device of the recyclable powder of this embodiment includes a powder collecting device and an AC electromagnet device; as figure 1 As shown, the AC electromagnet device includes a rod-shaped iron core 1 and an AC coil 2 wound outside the rod-shaped iron core 1, and the rod-shaped iron core 1 has an adsorption end 1-1 for absorbing magnetic powder or magnetic powder and iron powder; The outer periphery of the bar-shaped iron core 1 and the AC coil 2 is coaxially sleeved with a tubular yoke 3 for magnetic shielding, and both ends of the yoke 3 have inward annular turning edges 3-1, 3-2 , the turning edge 3-1 is overlapped and fixedly connected with the adsorption end 1-1 of the rod-shaped iron core 1, and the turning edge 3-2 is overlapped and fixedly connected with the other end of the rod-shaped iron core 1;

[0029] The magnetic yoke 3 is a yoke made of laminated silicon steel sheets, and its function is to constrain the magnetic field...

Embodiment 2

[0041] The material surface modification device of the recyclable powder of the present embodiment, such as figure 2 As shown, the difference from Embodiment 1 is that the AC electromagnet device also includes a magnetic flux leakage plate 4 for forming a directional alternating magnetic field with the AC electromagnet;

[0042] The length of one end close to the adsorption end 1-1 on the yoke 3 exceeds the rod-shaped iron core 1, and the turning edge 3-1 of this end is provided with a groove 5 for installing a magnetic leakage plate 4, such as image 3 As shown, the gap between the groove 5 and the mounting part of the magnetic leakage plate 4 is matched, so that the magnetic flux leakage plate 4 can randomly vibrate up and down, left and right when the direction of the magnetic force line changes; The gap size between the side wall, the bottom of the groove and the mounting part of the magnetic leakage plate 4 is 2 times of the aperture of the magnetic leakage hole of the m...

Abstract

The invention discloses a material surface modification device capable of recycling powder. The material surface modification device comprises a powder collection device and an alternating electromagnet device. The alternating electromagnet device comprises an iron core and an alternating current coil wound around the outer portion of the iron core, and the iron core is provided with an adsorption end for adsorbing magnetic powder or magnetic powder and iron powder. The powder collection device comprises a suction opening used for being formed below the adsorption end of the alternating electromagnet device, a gas outlet used for being connected with a gas pump and a powder adsorption and filtration collector arranged between the suction opening and the gas outlet. When the device is adopted for carrying out material surface modification, the alternating electromagnet device is located above a paint film to apply an alternating magnetic field, under the gas suction function of the gas pump, the gas rolling and attraction force borne by the magnetic powder or magnetic powder and iron powder, magnetically attracted to a magnetic attraction area, of the adsorption end is larger than magnetic attraction force, the powder enters the powder adsorption and filtration collector along with gas flow and is intercepted, and therefore the powder is collected. The collected powder can be used for measuring the powder precipitation rate or cyclically used for material surface modification.

Description

technical field [0001] The invention belongs to the technical field of material surface modification, and in particular relates to a material surface modification device for recyclable powder. Background technique [0002] The fan blade is one of the key parts of the fan, and the service life of the fan blade is directly related to the service life of the fan. The working environment of fan blades is harsh, and they are easily damaged by abrasion and covered by ice and snow. After the blades of the wind turbine are covered with ice, it will cause great harm: the original airfoil of the blades will be changed due to ice coating, which will greatly affect the load and output of the wind turbine, and greatly reduce the power generation efficiency of the wind turbine; A big security risk. Therefore, fan blades need to choose excellent protective coatings to achieve self-cleaning. [0003] Coating anti-icing is one of the active protection methods for fan blades. It mainly use...
