Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade recycling, in particular to a device for recycling waste wind turbine blades. Background Art

[0002] Wind turbine blades are mainly made of composite materials, with glass fiber reinforced resin (GRP, accounting for more than 90%) as the core component. Some large blades contain carbon fiber reinforced resin (CFRP). A single blade can weigh several tons and occupy a large area. The current environmentally friendly recycling method is to cut the blades and then use cutting and crushing (physical) to obtain fillers or building materials, or to decompose and recycle the cut blades (solvent, high temperature or catalyst decomposition) to obtain recycled high-value materials. The current mainstream cutting methods are manual cutting and excavator band saw cutting. The glass fiber dust generated during the cutting process is harmful to human health, especially in large-scale processing on large sites. Due to the high hardness of wind turbine blades, the saw blades are prone to vibration or deflection during cutting. If the size of the cut pieces is uneven, it will increase the difficulty of subsequent processing and affect the efficiency of subsequent physical recovery or thermal decomposition and chemical treatment.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention generates negative pressure suction through the fan, and sucks away the cutting dust produced in the arc-shaped protective shell through the dust suction bellows and transports it to the sliding box. The filter screen filters the air in the sliding box to prevent dust from overflowing the sliding box. After the sliding box is pulled out of the dust collection box, the dust in the sliding box can be cleaned, which is conducive to sucking away the dust generated during cutting; the arc-shaped protective shell and the saw blade move downward, and the saw blade rotates at the same time to cut the wind turbine blade. During the initial cutting, the first sealing ring of the arc-shaped protective shell does not contact the wind turbine blade, and dust is generated during cutting. A small amount of dust will escape from the arc-shaped protective shell, and most of it will be sucked away by the dust collection bellows. The arc-shaped protective shell moves downward, driving the dust collection bellows downward. The downward movement of the dust collection bellows drives the collar downward. The downward movement of the collar drives the elastic rope downward in the lubrication ring. The elastic rope is stretched and elastically deformed. At the same time, the elastic rope moves downward, pulling the first tension spring at the other end. The first tension spring is elastically deformed and stretched, and the dust collection bellows is in an elastically taut state. This is beneficial for the dust collection bellows to always be in a straightened state when the arc-shaped protective shell moves up and down, thereby preventing the dust collection bellows from being entangled with surrounding equipment.

[0020] 2. The third sealing ring of the negative pressure moving mechanism is closely attached to the surface of the wind turbine blade, and the small vacuum pump draws vacuum through the suction nozzle, so that the third sealing ring is in a negative pressure state, so that the auxiliary shell is firmly adsorbed on the wind turbine blade, and the auxiliary shell is firmly adsorbed on the wind turbine blade, so that the main shell is firmly adsorbed on the wind turbine blade. The rotation of the electric hub of the negative pressure moving mechanism drives the rotating disc to move, and the movement of the rotating disc drives the auxiliary shell to move, so that the equipment can move on the wind turbine blade, and the auxiliary shell is adsorbed on the wind turbine blade, so that the equipment is firmly fixed on the wind turbine blade while moving, so that the vibration of the saw blade is reduced when cutting, and the overall stability is more stable. The output shaft of the servo motor of the reversing assembly rotates to drive the driving gear to rotate, and the driving gear rotates to drive the driven gear to rotate, and the driven gear rotates to drive the rotating disc to rotate. The rotation of the rotating disc drives the electric hub to rotate a certain angle, and the rotation of the electric hub drives the equipment to move, so as to realize the adjustment of the moving direction of the equipment, which is conducive to the equipment being adsorbed on the wind turbine blade for mobile cutting and improving the stability during cutting;

[0021] 3. By placing the two base plates in the preset appropriate positions, the wire rope is in a taut state, loosening the limit screws, and moving the sliding rod up and down so that the wire rope is above the wind turbine blade, and the distance between the wire rope and the wind turbine blade at each position is within the preset range. When the equipment deviates from the line pulled by the wire rope, the vertical wheel contacts the wire rope and receives the reaction force of the wire rope, causing the vertical wheel to move left and right. The vertical wheel moves and contacts the pressure sensor, and the pressure sensor transmits an electrical signal to the external controller. The external controller controls the equipment to adjust the direction of advance so that the offset of the vertical wheel on the wire rope is within the preset range. At this time, the pressure value detected by the pressure sensor is within the preset range, and the external controller stops controlling the equipment to adjust the direction of advance, which is conducive to the equipment moving along the line pulled by the wire rope, so that there will not be too much deviation during cutting, and the size uniformity after cutting is maintained.

One end of the two dust collection bellows 33 is fixedly mounted on the arc-shaped protective shell 31, and the collar 34 is slidably connected to the dust collection bellows 33. The lubricating ring 35 is fixedly mounted on the main shell 1, and one end of the elastic rope 36 passes through the lubricating ring 35 and is fixedly connected to the collar 34. One end of the first tension spring 37 is fixedly mounted on the main shell 1, and the end of the elastic rope 36 away from the lubricating ring 35 is fixedly connected to the end of the first tension spring 37 away from the main shell 1. The dust-free cutting mechanism 3 also includes: a collection box mechanism, which is mounted on the left side of the main shell 1.

[0042] The negative pressure moving mechanism 2 generates negative pressure so that the device can be adsorbed on the waste wind turbine blades, and can drive the device to move while adsorbing. The dust-free cutting mechanism 3 cuts the wind turbine blades and cleans the dust such as glass fiber generated by the cutting. The limit detection mechanism 4 can detect whether the movement of the device deviates from the preset setting to avoid deviation when the device moves and cuts.

[0043] The arc-shaped protective shell 31 and the saw blade 32 of the dust-free cutting mechanism 3 move downward, and the saw blade 32 rotates at the same time to cut the wind turbine blade. During the initial cutting, the first sealing ring 38 of the arc-shaped protective shell 31 does not contact the wind turbine blade.
