Description

Technical Field

[0001] This utility model relates to the technical field of slag recycling equipment, and in particular to a slag recycling equipment for waste incineration power generation. Background Technology

[0002] Waste-to-energy incineration, as an important way to reduce and recycle waste, generates a large amount of slag while processing municipal solid waste. This slag contains a certain amount of metallic impurities such as iron blocks. If it is directly landfilled or discarded, it will not only waste resources but may also pollute the environment due to problems such as metal corrosion.

[0003] However, existing slag recovery equipment for waste-to-energy incineration has significant shortcomings in iron separation efficiency. Traditional equipment mostly uses a single magnetic separator to process the slag. Because the slag is loose after incineration and iron pieces are often mixed and adhered with other impurities, a single magnetic separator cannot quickly penetrate the dense slag layer, resulting in some iron pieces not being effectively adsorbed. Utility Model Content

[0004] In view of the technical problem that traditional equipment mostly uses a single magnetic separation device to process slag, since the slag is loose after incineration and iron blocks are often mixed and adhered with other impurities, the single magnetic separation device cannot quickly penetrate the dense slag layer, resulting in some iron blocks not being effectively adsorbed. This utility model provides a slag recycling device for waste incineration power generation.

[0005] The technical solution adopted by this utility model is: a waste incineration power generation slag recycling device, including a belt conveyor and a vibrating screening assembly disposed on one side of the belt conveyor. The discharge end of the vibrating screening assembly is provided with a support base. The support base has an arc-shaped groove. A rotating drum is rotatably connected inside the support base. A drive motor is fixedly connected to the outside of the support base. The output end of the drive motor is fixedly connected to the rotating drum. A scraper is also fixedly connected to the support base. One end of the scraper is in contact with the rotating drum. The rotating drum is made of permanent magnet material.

[0006] A further feature of this invention is that the vibrating screening assembly includes a vibrating box and a screen fixedly connected inside the vibrating box. A frame is provided below the vibrating box, and multiple sets of springs are connected between the frame and the vibrating box. A vibrating motor is fixedly connected to the outside of the vibrating box.

[0007] A further feature of this invention is that a guide plate is fixedly connected to the lower part of the vibration box, and the guide plate is inclined.

[0008] A further feature of this invention is that the inner bottom of the support base is provided with a discharge port, a sealing block is slidably connected in the discharge port, a sliding plate is fixedly connected to the bottom of the sealing block, a cylinder is fixedly connected inside the support base, and the output end of the cylinder is fixedly connected to the sliding plate.

[0009] A further feature of this invention is that the scraper has an arc-shaped edge on the side near the rotating drum, and the arc-shaped edge is in contact with the rotating drum. Side plates are fixedly connected to both sides of the scraper.

[0010] A further feature of this invention is that the rotating drum has a hollow structure, and support legs are fixedly connected to the bottom of the support base around all four sides.

[0011] A further feature of this invention is that side plates are fixedly connected to both sides of the top of the guide plate.

[0012] The beneficial effects of this utility model are as follows: It solves the problem of slow separation of iron blocks from slag. The vibrating screen component first separates fine slag from solid materials, reducing the magnetic separation load and preventing impurities from obscuring the iron blocks. The permanent magnet drum has strong magnetic force, which can quickly adsorb ferromagnetic metals, and the fitted arc-shaped scraper thoroughly removes them, resulting in efficient separation. The belt conveyor connects smoothly with each component, enabling continuous operation. The overall design improves the speed and purity of iron block separation, increases resource recovery rate, shortens the processing cycle, and meets the slag treatment needs of waste incineration power generation.

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0021] To address the problems existing in the background technology, this application proposes the following technical solution: a waste incineration power generation slag recycling device, comprising a belt conveyor 1 and a vibrating screen assembly disposed on one side of the belt conveyor 1. The discharge end of the vibrating screen assembly is provided with a support base 8, the support base 8 has an arc-shaped groove, a rotating drum 10 is rotatably connected inside the support base 8, a drive motor 9 is fixedly connected to the outside of the support base 8, the output end of the drive motor 9 is fixedly connected to the rotating drum 10, a scraper 11 is also fixedly connected to the support base 8, one end of the scraper 11 is in contact with the rotating drum 10, the rotating drum 10 is made of permanent magnet material and has a hollow structure, and support legs are fixedly connected to the bottom of the support base 8 around its perimeter; the belt conveyor 1, as the first link in slag transportation, can stably and continuously transport the slag produced after waste incineration to the vibrating screen assembly, replacing manual handling, reducing the frequency of manual contact with slag, reducing operational risks, and ensuring the continuity of slag transportation, providing a stable material source for subsequent processing. The vibrating screen assembly is responsible for the initial separation of slag, separating larger solid materials from fine slag, in preparation for subsequent ferromagnetic metal recovery.

[0022] The arc-shaped groove inside the support base 8 matches the shape of the rotating drum 10, ensuring its stability during rotation and preventing swaying from affecting the adsorption effect. The rotating drum 10 is made of permanent magnet material, utilizing strong magnetism to efficiently adsorb ferromagnetic metals such as iron, cobalt, and nickel from the slag, achieving metal separation from the slag. The hollow structure, while maintaining magnetic strength, reduces the weight of the rotating drum 10, lowering the load on the drive motor 9 and extending the equipment's service life. The drive motor 9 provides continuous power to the rotating drum 10, ensuring its uniform rotation and guaranteeing that the adsorbed metal is stably transported to the scraper 11.

[0023] The scraper 11 fits tightly against the rotating drum 10, effectively scraping away the metal adsorbed on its surface. This prevents continuous metal adhesion from affecting subsequent adsorption. The scraped metal is collected under gravity, facilitating recycling. The support legs at the bottom of the support base 8 elevate the entire device, facilitating the installation of a collection device below and enhancing its stability, preventing tipping during vibration or rotation of the drum 10. The overall structure combines conveying, screening, and magnetic separation functions, achieving efficient metal recovery from slag and improving resource utilization.

[0024] In this embodiment, a cylinder 12 is fixedly connected inside the support base 8, and the output end of the cylinder 12 is fixedly connected to the slide plate 13. The scraper 11 has an arc-shaped edge on the side near the rotating drum 10, and fits against the rotating drum 10 through the arc-shaped edge. Side plates are fixedly connected to both sides of the scraper 11. The cylinder 12 inside the support base 8 can drive the slide plate 13 to move by telescopic movement, thereby controlling the opening and closing of the subsequent discharge port 15. This allows for flexible adjustment of the discharge timing according to the amount of metal collected, avoiding excessive metal accumulation and overflow. When it is necessary to discharge the collected metal, the cylinder 12 drives the slide plate 13 to move and open the discharge port 15, and then closes it after completion. The operation is convenient and can effectively control the discharge speed.

[0025] The curved edge of the scraper 11 perfectly fits the surface of the rotating drum 10, ensuring that the metal adsorbed on its surface is completely scraped off when the drum 10 rotates, preventing residual metal from affecting the magnetic adsorption effect and improving the thoroughness of metal separation. The side plates on both sides of the scraper 11 prevent the scraped metal from falling off, ensuring that the metal falls accurately into the collection area below, reducing metal loss and improving recycling efficiency. This design makes the scraper 11 both efficient and precise during the scraping process, further guaranteeing the separation effect of ferromagnetic metals.

[0026] In this embodiment, the vibrating screening assembly includes a vibrating box 5 and a screen 7 fixedly connected inside the vibrating box 5. A frame 2 is provided below the vibrating box 5, and multiple sets of springs 3 are connected between the frame 2 and the vibrating box 5. A vibrating motor 6 is fixedly connected to the outside of the vibrating box 5. A guide plate 4 is fixedly connected below the vibrating box 5. The guide plate 4 is inclined, and a side plate support seat 8 is fixedly connected to both sides of the top of the guide plate 4. A discharge port 15 is provided at the bottom of the guide plate 4. A blocking block 14 is slidably connected in the discharge port 15, and a sliding plate 13 is fixedly connected to the bottom of the blocking block 14. The vibrating box 5 of the vibrating screening assembly generates high-frequency vibration through the vibrating motor 6, which drives the internal screen 7 to vibrate synchronously. This causes the slag entering the vibrating box 5 to continuously jump on the screen 7. Fine slag particles fall through the gaps in the screen 7, while larger solid materials (including ferromagnetic metals) are intercepted and transported to the subsequent magnetic separation stage, realizing the initial grading and separation of the slag. The frame 2 provides stable support for the vibrating box 5. The multiple sets of springs 3 between the frame 2 and the vibrating box 5 play a buffering role, reducing the impact of vibration on the frame 2 and the ground, while increasing the vibration amplitude of the vibrating box 5 and improving the screening efficiency.

[0027] The guide plate 4 below the vibrating box 5 is inclined to guide the screened solid material smoothly into the support base 8, preventing material accumulation at the outlet of the vibrating box 5. The side plates on both sides of the guide plate 4 prevent material from leaking out from the sides during the sliding process, ensuring that all material enters the magnetic separation area. The discharge port 15 at the bottom of the support base 8 is used to discharge the separated metal. The sealing block 14 is connected to the slide plate 13. The opening and closing of the discharge port 15 is controlled by the movement of the slide plate 13. When the accumulated other metals or solids reach a certain amount, the slide plate 13 is moved to open the sealing block 14, and the material can be discharged from the discharge port 15 for centralized collection and processing.

[0028] The usage method of this embodiment is as follows:

[0029] In use, the slag crushed by the crusher is conveyed by the belt conveyor 1 and then conveyed into the vibrating box 5. The vibrating box 5 is driven to vibrate by the vibrating motor 6, thereby realizing the separation of slag from solid materials (iron blocks).

[0030] Solid materials fall into the support base 8 and drive the rotating drum 10 to rotate via the drive motor 9. Since the rotating drum 10 is made of permanent magnet material, the surface magnetic field strength can reach 15000Gs, which is used to separate ferromagnetic metals such as iron, cobalt, and nickel from the slag. When the slag is transported to the bottom of the rotating drum 10, the ferromagnetic metals are adsorbed on the surface of the rotating drum 10 and carried to the scraper 11 as the rotating drum 10 rotates. The scraper 11 scrapes off the solid materials and they fall off under the action of gravity, thus achieving the full separation of ferromagnetic metals.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
