Description

Technical Field

[0001] This utility model relates to the field of decommissioned wind turbine blade recycling technology, specifically a decommissioned wind turbine blade recycling and processing device. Background Technology

[0002] With the rapid development of the global wind power industry, a large number of wind turbine blades have entered the retirement stage after reaching the end of their service life. Since wind turbine blades are mainly made of composite materials such as glass fiber reinforced plastic (GFRP) or carbon fiber reinforced plastic (CFRP), their recycling and processing face challenges such as high technical difficulty, high cost, and low resource utilization rate. Therefore, developing efficient and environmentally friendly recycling and processing technologies for retired wind turbine blades is of great significance for promoting the sustainable development of the wind power industry.

[0003] Decommissioned wind turbine blades are recycled through mechanical means. The blades are cut into small pieces and then further crushed into fine particles by a crusher. The crushed material can be used as filler in building materials (such as concrete and asphalt) and roadbed materials.

[0004] When existing wind turbine blade recycling devices are in operation, foreign objects such as iron nails and screws cannot be removed after the wind turbine blades are crushed. The presence of metal parts such as iron nails and screws reduces the purity of the recycled material and affects its subsequent processing and utilization value. Therefore, a decommissioned wind turbine blade recycling and processing device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a decommissioned wind turbine blade recycling and processing device, which has the advantages of removing iron nails and screws from the crushed recycled material. This solves the problem that existing wind turbine blade recycling devices cannot remove foreign objects such as iron nails and screws after the wind turbine blades are crushed. The presence of iron nails and screws reduces the purity of the recycled material and affects its subsequent processing and utilization value.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a decommissioned wind turbine blade recycling and processing device, comprising a recycling box, wherein a crushing structure is installed inside the recycling box, and a cleanup structure is installed inside the recycling box;

[0007] The crushing structure includes a first motor, which is fixedly installed on the outside of the recycling box. A first gear is rotatably installed on the inner wall of the recycling box.

A sliding sleeve is slidably installed outside the slide rod. A second motor is fixedly installed outside the sliding sleeve. A second gear is rotatably installed inside the sliding sleeve. An electromagnet is fixedly installed outside the sliding sleeve. A collection block is fixedly installed inside the recycling bin. A discharge channel is opened inside the collection block.

[0014] Furthermore, the front of the collection drawer extends through the recycling bin and is movably connected to the front of the recycling bin, and the filter plate is engaged with the inner wall of the collection drawer.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The retired wind turbine blade recycling and processing device in this embodiment includes a recycling box 1, a crushing structure 2 installed inside the recycling box 1, and a cleaning structure 3 installed inside the recycling box 1.

[0025] The crushing structure 2 includes a first motor 201. The first motor 201 is fixedly installed on the outside of the recycling box 1. A first gear 202 is rotatably installed on the inner wall of the recycling box 1. A crushing roller 203 is fixedly installed on the outside of the first gear 202. A guide plate 204 is fixedly installed inside the recycling box 1. A slide rail 205 is fixedly installed inside the recycling box 1. A collection drawer 206 is slidably installed inside the slide rail 205. A filter plate 207 is movably installed inside the collection drawer 206.

[0026] The impurity removal structure 3 includes a slide bar 301. The slide bar 301 is fixedly installed inside the recycling bin 1. A limiting tooth 302 is fixedly installed outside the slide bar 301. A sliding sleeve 303 is slidably installed outside the slide bar 301. A second motor 304 is fixedly installed outside the sliding sleeve 303. A second gear 305 is rotatably installed inside the sliding sleeve 303. An electromagnet 306 is fixedly installed outside the sliding sleeve 303. A collection block 307 is fixedly installed inside the recycling bin 1. A discharge channel 308 is opened inside the collection block 307.

[0027] exist Figure 3 In this process, the electromagnet 306 is existing technology. It can be opened and closed by the control panel on the front of the recycling bin 1. The bottom of the electromagnet 306 is close to the top of the filter plate 207. When the electromagnet 306 moves left and right above the filter plate 207, it can attract metal parts such as nails and screws in the recycled material on the top of the filter plate 207.

[0028] exist Figure 2 In the process, the crushing roller 203 crushes the fan blades, but can only crush the plastic material in the fan blades. The crushed and recycled fragments will fall on the surface of the filter plate 207. The filter plate 207 is a certain distance from the inner bottom wall of the collection tray 206, and the filter plate 207 can filter the recycled material.

[0029] exist Figure 1 In the process, larger recycled materials after crushing will fall onto the surface of the filter plate 207. After the metal parts such as nails and screws are adsorbed, the collection drawer 206 is pulled out, the filter plate 207 is taken out, and the recycled materials on the surface of the filter plate 207 are put back into the recycling box 1 for secondary crushing.

[0030] During implementation, the following steps are performed: When in use, the fan blades are crushed by the crushing roller 203. By turning on the second motor 304, the electromagnet 306 attracts metal parts such as nails and screws in the crushed recycled material, thereby removing the metal parts such as nails and screws and improving the purity of the recycled material.

[0031] In summary, this decommissioned wind turbine blade recycling device crushes the wind turbine blades using a crushing roller 203. The crushed recycled material falls onto the surface of the filter plate 207 inside the collection tray 206 via a guide plate 204. By activating the second motor 304, the second gear 305 rotates. According to the distribution of the limiting teeth 302, the sliding sleeve 303 moves along the sliding rod 301, simultaneously moving the electromagnet 306. Activating the electromagnet 306 allows it to process iron nails and screws in the crushed recycled material. Metal parts such as wires are attracted until the electromagnet 306 moves above the discharge channel 308. Then the electromagnet 306 is turned off, and metal parts such as nails and screws fall into the discharge channel 308, thus completing the removal of metal parts such as nails and screws. This improves the purity of the recycled material and solves the problem that in existing wind turbine blade recycling devices, foreign objects such as nails and screws cannot be removed after the wind turbine blades are crushed. The presence of the filter plate 207 reduces the purity of the recycled material, affecting its subsequent processing and utilization value.
