Description

Technical Field

[0001] The utility model relates to the technical field of wind power, and in particular to a crushing and recycling device for discarded wind power blades. Background Art

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean, pollution-free renewable energy source that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. People are interested in how to use wind to generate electricity. However, the wind turbine blades used in wind power generation will be damaged and scrapped after long-term use. In the recycling of discarded wind turbine blades, it is often necessary to crush and recycle the discarded wind turbine blades, so a crushing and recycling device for discarded wind turbine blades is needed.

[0003] When the existing waste wind turbine blade crushing and recycling device is used, since the waste wind turbine blades are large, various small fragments and large fragments will be generated during the first crushing, and the existing waste wind turbine blade crushing and recycling device will collect them all, so manual secondary sorting is required, and then the larger fragments are put back into the device for crushing until they are completely crushed into smaller fragments. This not only increases the workload of the workers, but also greatly reduces the crushing efficiency and affects the recovery speed of the waste wind turbine blades. Therefore, in view of the above technical problems, a waste wind turbine blade crushing and recycling device is proposed herein. Utility Model Content

The rotating plate collides with the device through a vibration mechanism outside the device to achieve vibration, and small fragments fall into a second collection box through the screen holes, and large fragments slide into a first collection box. For larger fragments that cannot pass through the opening, the screen plate is slid by pulling a pull rod to expose the hollow structure of the rotating plate, allowing the fragments to fall into the second collection box, thereby simplifying the fragment sorting process and improving the recovery efficiency.

The device comprises a rotatable rotating plate arranged inside the device, an opening arranged outside the device body, and the rotating plate is extended outside the device through the opening, and a sieve plate with sieve holes is slidably connected inside the rotating plate. A vibration mechanism is arranged outside the device body so that the rotating plate and the device body continuously collide to achieve vibration, thereby screening the wind turbine blade fragments crushed on the rotating plate, wherein smaller fragments can pass through the sieve holes and fall into a No. 2 collecting box, while larger fragments can slide off the rotating plate and slide through the opening into a No. 1 collecting box outside the device body.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A feeding port 2 is provided on the upper side of the device body 1, and a slide plate 3 is slidably connected to the inside of the feeding port 2. The feeding port 2 can be blocked by the slide plate 3 to prevent debris from flying out and causing injuries to people.

[0025] The crushing mechanism includes a rotating rod 5 and a crushing column 6. The rotating rod 5 is fixedly connected to the No. 1 motor 4, and the rotating rod 5 is rotatably connected to the device body 1. The crushing column 6 is fixedly connected to the rotating rod 5, and the two groups of crushing columns 6 are meshed. By running the No. 1 motor 4, the rotating rod 5 can be rotated, thereby causing the crushing column 6 to rotate and engage, and the discarded wind turbine blades can be crushed.

[0026] The rotating plate 9 passes through the opening 7 , and the exterior of the rotating plate 9 is a hollow structure. The sieve plate 11 covers the hollow structure of the rotating plate 9 , and the opening 7 can exclude some larger fragments.

[0027] The outside of the sieve plate 11 is provided with sieve holes 13, through which the crushed fragments can be screened, thereby reducing the subsequent sorting tasks.

[0028] The outside of the device body 1 is fixedly connected to a No. 1 collection box 19, and the end of the rotating plate 9 is located above the No. 1 collection box 19. The fragments can pass through the opening 7 and slide into the No. 1 collection box 19 following the inclination of the rotating plate 9. A No. 2 collection box 20 is placed at the inner bottom of the device body 1.

[0029] The working principle of a crushing and recycling device for discarded wind turbine blades based on an embodiment is that when using this device to crush discarded wind turbine blades, the discarded wind turbine blades are first simply broken and put into the device body 1 through the feeding port 2, and then the rotating rod 5 is rotated by the No. 1 motor 4 to make the crushing column 6 rotate and engage, so as to crush the discarded wind turbine blades. At this time, the crushed fragments will fall onto the rotating plate 9. At this time, the No. 2 motor 16 can be operated to make the rotating shaft 17 drive the abutment plate 18 to rotate. Since the abutment plate 18 is in contact with the rotating plate 9, the end of the rotating plate 9 can be lifted and rotated around the fixed rod 8 until the abutment plate 18 is separated from the rotating plate 9. At this time, the rotating plate 9 will fall rapidly and collide with the bottom of the opening 7, thereby realizing the overall vibration of the rotating plate 9, that is, The vibration of the sieve plate 11 inside the rotating plate 9 can be achieved, so as to screen the crushed fragments, wherein smaller fragments can fall into the No. 2 collecting box 20 through the sieve holes 13 of the sieve plate 11, while larger fragments can slide through the rotating plate 9 into the No. 1 collecting box 19 outside the device body 1. At this time, if larger fragments that cannot pass through the opening 7 still remain above the rotating plate 9, the No. 2 collecting box 20 can be taken out first, and then the pull rod 14 can be pulled to pull out the sieve plate 11, thereby exposing the hollow structure outside the rotating plate 9. The larger fragments above the rotating plate 9 will fall into the bottom of the device body 1 through the hollow structure of the rotating plate 9 for collection. In this way, the screening of various types of fragments can be completed, which is convenient for later processing, reduces manual sorting, and improves the crushing and recycling efficiency.
