Description

Technical Field

[0001] This utility model relates to the field of iron removal technology, specifically a self-unloading iron remover for removing powdery iron from decommissioned wind turbine blades. Background Technology

[0002] A magnetic separator is a device that generates a strong magnetic field to attract and remove ferromagnetic impurities mixed in materials. This ensures the safe and normal operation of machinery such as crushers and grinders in the conveying system. It also effectively prevents accidents caused by large or long iron pieces tearing the conveyor belt and significantly improves the quality of raw materials. With the rapid development of the wind power industry, a large number of wind turbine blades have reached the end of their service life and entered the retirement stage. During the recycling process, retired wind turbine blades need to be crushed into powder for subsequent reuse or further processing.

[0003] In existing iron separators, materials are typically transported by belt conveyor, and permanent magnets installed on one side of the belt adsorb ferromagnetic substances in the material. When the belt reaches a certain position, an iron unloading device removes the ferromagnetic substances adsorbed on the belt. During the iron removal process, a certain amount of non-ferromagnetic powder remains on the belt surface. The accumulated non-ferromagnetic powder affects the friction between the belt and the drive and driven pulleys, causing belt slippage, affecting the normal operation of the equipment, and reducing the iron removal efficiency. Therefore, a self-unloading iron separator for removing powdery iron from decommissioned wind turbine blades is proposed. Summary of the Invention

Example

[0030] Please see Figure 1-5This utility model provides a technical solution: a self-unloading iron separator for removing iron debris from decommissioned wind turbine blades. The separator body 1 uses a rare-earth neodymium iron boron permanent magnet as its magnetic source. When material passes under the separator body 1, ferromagnetic impurities are attracted to the surface of a belt 6 by the permanent magnet. The belt 6 continuously rotates, transporting the attracted iron impurities to a non-magnetic zone. In the non-magnetic zone, the iron impurities fall into a collection box 4 due to the weakened magnetic field. A belt 6 is located on one side of the separator body 1; a cleaning component 2 is also located on one side of the separator body 1. The cleaning component 2 scrapes away residual non-ferromagnetic powder from the surface of the belt 6. Under the inertia of the separator body 1, the attracted iron debris detaches from the surface of the belt 6 when it reaches the discharge end and is fed into a limiting cover 3. Subsequently, the iron debris falls into the collection box 4 through the discharge port at the bottom of the limiting cover 3, achieving centralized collection and treatment of the iron debris.

[0031] The cleaning component 2 includes a fixing frame 23, with a second slide groove 29 inside the fixing frame 23. A limit block 210 is fixed to the inner wall of the second slide groove 29, and a slide plate 25 is slidably connected to the inner wall of the second slide groove 29. A scraper 26 is fixed to one side of the slide plate 25, and one end of the scraper 26 is slidably connected to one side of the belt 6. The scraper 26 is slidably connected to the belt 6 to scrape off residual non-ferromagnetic powder from the surface of the belt 6. Through the linkage design of the spring 28 and the slide plate 25, flexible contact between the scraper 26 and the belt 6 is achieved. The material of the scraper 26 can be rubber or polyurethane.

[0032] A push plate 24 is inserted into the inner side of the second slide groove 29. Several springs 28 are connected between the push plate 24 and the slide plate 25. The push plate 24 pushes the slide plate 25 through the springs 28 to ensure that the scraper 26 is dynamically in contact with the belt 6. The limiting block 210 is located on one side of the slide plate 25. The outer side of the scraper 26 moves through one side of the fixing frame 23. A limiting plate 22 is fixed on one side of the push plate 24. A first slide groove 27 is opened on one side of both the limiting plate 22 and the push plate 24. The slide plate 25 and the scraper 26 can be quickly separated by sliding the pull rod 21 along the first slide groove 27, which is convenient for replacing vulnerable parts.

[0033] A pull rod 21 is slidably connected to the inner side of the first slide groove 27. One end of the pull rod 21 is fixed to one side of the slide plate 25. When the spring 28 and the scraper 26 need maintenance, it is only necessary to remove the bolt on one side of the limit plate 22, remove the limit plate 22 and the fixing bracket 23, and then the spring 28 can be removed separately, or the pull rod 21 can be pulled to drive the slide plate 25 and the scraper 26 away from the inner side of the second slide groove 29.

[0034] A support frame 5 is fixed to the outside of the iron separator body 1. A belt conveyor for conveying decommissioned wind turbine blade powder is installed on the lower side of the iron separator body 1. A protective cover 7 is fixed to the top of the support frame 5, which is located around the iron separator body 1. The protective cover 7 is used to protect the iron separator body 1 from the influence of the external environment, such as preventing dust and moisture from entering the equipment. A limit cover 3 is fixed to one side of the support frame 5. A limit plate 22 is bolted to one side of the limit cover 3. The fixing frame 23 is fixed to the inner wall of the limiting cover 3. The limiting cover 3 is located at the discharge end of the belt 6. After the iron remover body 1 removes the scrap iron from the wind turbine blade powder, the scrap iron is sent into the limiting cover 3 under the inertia of the iron remover body 1 and falls into the inner side of the collection box 4. The bottom of the limiting cover 3 is provided with a discharge port, and the bottom of the discharge port is provided with a collection box 4. The limiting cover 3 fixed on one side of the support frame 5 is located at the discharge end of the belt 6 to limit the falling range of the scrap iron and ensure that the scrap iron can fall accurately into the inner side of the collection box 4.

[0035] In this embodiment, the iron separator body 1 is model RCYL-08, and the iron separator body 1 has a self-unloading function. Since the structure and operating principle of this model of iron separator body 1 are existing technologies, its structure and operating principle will not be described in detail here.

[0036] Working principle: When the iron separator body 1 is activated, it adsorbs and removes the impurities in the powder from the decommissioned wind turbine blades. During the iron removal process, the powder is conveyed to the bottom of the iron separator body 1 via a belt conveyor. The iron separator body 1 uses magnetic force to adsorb the ferromagnetic impurities in the powder. Under the action of inertia, the adsorbed impurities move with the iron separator body 1 to the inside of the limiting cover 3. The iron separator body 1 then conveys the adsorbed impurities into the limiting cover 3. The impurities fall freely through the discharge port at the bottom of the limiting cover 3 into the collection box 4, completing the automatic unloading.

[0037] When the belt 6 moves to the cleaning component 2 position, the scraper 26 fixed to one side of the slide plate 25 contacts the surface of the belt 6 and slides to one side of the belt 6. The scraper 26 scrapes away the non-ferromagnetic powder remaining on the surface of the belt 6, ensuring the cleanliness of the surface of the belt 6. The push plate 24 is inserted into the inner side of the second slide groove 29 and is connected to the slide plate 25 through several springs 28. The springs 28 provide elastic support, so that the scraper 26 can fit tightly against the surface of the belt 6, improving the scraping effect.

[0038] The limiting block 210 is fixed to the inner wall of the second slide groove 29 and is located on one side of the slide plate 25. The limiting block 210 restricts the sliding range of the slide plate 25 within the second slide groove 29, prevents the slide plate 25 from dislodging from the second slide groove 29, and ensures the stable operation of the cleaning assembly 2.

[0039] When maintenance of spring 28 or scraper 26 is required, simply remove the bolts on one side of limit plate 22 and remove limit plate 22 and fixing bracket 23. Then, spring 28 can be removed separately for replacement or repair. If scraper 26 needs to be replaced, pull rod 21 to move slide plate 25 and scraper 26 away from the inside of second slide groove 29 for easy replacement.

[0040] In summary, when the belt 6 runs to the cleaning component 2, the scraper 26 fixed on one side of the slide plate 25 contacts and slides with the surface of the belt 6, which can scrape off the non-ferromagnetic powder remaining on the surface of the belt 6, ensuring the cleanliness of the belt 6 surface, ensuring the stability and reliability of the subsequent operation of the belt 6, and reducing problems such as belt 6 wear caused by powder residue.

[0041] When maintenance of spring 28 or scraper 26 is required, simply remove the bolts on one side of limit plate 22 to easily remove limit plate 22 and fixing bracket 23. Then spring 28 or scraper 26 can be removed separately for replacement or repair, making maintenance more targeted and flexible, reducing maintenance costs, and facilitating staff to quickly replace spring 28 or scraper 26, ensuring the normal operation of cleaning component 2.

[0042] Once activated, the iron separator body 1 can quickly adsorb and remove impurities from the powder of decommissioned wind turbine blades. By using magnetic force to directly act on the ferromagnetic impurities in the powder, the iron removal efficiency can be effectively improved, ensuring the purity of the powder and meeting the powder quality requirements for subsequent processing or utilization.
