Abstract
Description
Technical Field
[0001] This utility model relates to the field of slag sorting technology, specifically to a multi-stage sorting device for waste incineration slag. Background Technology
[0002] The slag from municipal solid waste incineration power plants is mainly a heterogeneous mixture composed of stones, sand, glass, ceramics, ash, metals, and a small amount of unburned waste. After crushing and sorting, the slag has stable chemical properties, good durability, and high strength. Slag is a non-toxic general waste that can be directly landfilled or processed for utilization. After technical processing, the slag is suitable for making non-fired bricks or other building materials and has a certain recycling value.
[0003] Slag sorting is a crucial step in resource recycling and environmental protection. Its purpose is to separate useful substances such as metals and sand from slag using various technologies and equipment. Most existing slag sorting equipment on the market only uses single screening or magnetic separation methods, failing to perform multi-stage sorting of slag, resulting in low purity of the sorted material.

[0007] A pre-screening assembly is installed on the upper left side of the frame. The pre-screening assembly includes an inclined screen box. The inclined screen box has a screening chamber and a discharge chamber inside. A screen is provided between the screening chamber and the discharge chamber. A second discharge port is provided at the right end of the discharge chamber. An inlet is opened at the upper left end of the inclined screen box.
[0008] Preferably, the second discharge port extends to the right side wall of the inclined screen box, and the second discharge port is located above the conveyor belt, so that the screened slag can fall directly onto the conveyor belt.
[0009] Preferably, the feed inlet is connected to the screening chamber, and a first discharge port is provided at the rear right end of the inclined screen box corresponding to the position of the screening chamber. A first guide plate is provided at the rear end of the first discharge port. The design of the first discharge port and the first guide plate enables the large volume slag after screening in the screening chamber to be discharged along a predetermined path, which facilitates the collection and subsequent processing of large volume slag.
[0010] Preferably, the bottom wall of the discharge chamber and the screen are both set as an inclined structure with the left side higher than the right side. The inclined screen facilitates the movement of slag on the screen, making it convenient to perform preliminary screening of the slag. The inclined bottom wall of the discharge chamber facilitates the discharge of slag from the discharge chamber.
[0011] Preferably, a vibration motor is installed on the top of the inclined screen box, and multiple shock absorbers are connected between the bottom of the inclined screen box and the upper left side of the frame.

[0012] Preferably, the iron removal assembly includes a support frame connected to the machine frame, a belt inside the support frame, and an iron remover inside the belt, which can effectively remove iron impurities from the slag and prevent iron impurities from entering.
[0013] Preferably, a second guide plate is provided on the front side of the support frame. The second guide plate is located below the front end of the belt. After the iron impurities are separated from the belt, they fall onto the second guide plate and slide down along the second guide plate, which facilitates the collection of iron impurities. The height limit plate is connected to the support frame. The height limit plate can scrape the slag on the conveyor belt and prevent the slag from accumulating too high and affecting the adsorption of iron impurities in the slag by the iron remover.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] 1. Through a multi-stage sorting structure including pre-screening components, iron removal components, and sorting magnetic rollers, it is possible to perform fine sorting of waste incineration slag, effectively separating slag of different particle sizes and materials, improving resource recovery rate, and realizing the resource utilization of waste incineration slag;

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figures 1 to 5 The multi-stage sorting device for waste incineration slag shown includes:
[0027] The frame 1 has a conveyor belt 2 on its right side. One end of the conveyor belt 2 is nested with a rotating roller 3. The other end of the conveyor belt 2 is connected to a sorting magnetic roller 4. An iron removal component 8 is located above the middle of the conveyor belt 2. A height limit plate 24 is located on the left side of the iron removal component 8. A material distribution plate 5 is located on the right side of the conveyor belt 2. A slag outlet 6 is located below the left side of the material distribution plate 5. An aluminum discharge outlet 7 is located on the right side of the material distribution plate 5.
[0028] The pre-screening assembly 9 is installed on the upper left side of the frame 1. The pre-screening assembly 9 includes an inclined screen box 10. The inclined screen box 10 is provided with a screening chamber 11 and a discharge chamber 12. A screen 13 is provided between the screening chamber 11 and the discharge chamber 12. A second discharge port 16 is provided at the right end of the discharge chamber 12. A feed port 17 is opened at the upper left side of the inclined screen box 10.
[0029] The second discharge port 16 extends to the right side wall of the inclined screen box 10. The second discharge port 16 is located above the conveyor belt 2, so that the screened slag can fall directly onto the conveyor belt 2.
[0030] The feed inlet 17 is connected to the screening chamber 11. The rear right end of the inclined screen box 10 is provided with a first discharge port 14 corresponding to the position of the screening chamber 11. The rear end of the first discharge port 14 is provided with a first guide plate 15. The design of the first discharge port 14 and the first guide plate 15 enables the large volume slag after screening in the screening chamber 11 to be discharged along a predetermined path, which facilitates the collection and subsequent processing of large volume slag.
[0031] The bottom wall of the discharge chamber 12 and the screen 13 are both designed with an inclined structure that is higher on the left and lower on the right. The inclined screen 13 facilitates the movement of slag on the screen 13 and makes it easier to perform preliminary screening of slag. The inclined bottom wall of the discharge chamber 12 facilitates the discharge of slag from the discharge chamber 12.
[0032] A vibration motor 18 is installed on the top of the inclined screen box 10. Multiple shock absorbers 19 are connected between the bottom of the inclined screen box 10 and the upper left side of the frame 1. The installation of the vibration motor 18 can effectively drive the inclined screen box 10 to vibrate, so that the material is evenly distributed on the screen 13 and the screening is accelerated, thereby improving the screening effect.
[0033] The iron removal assembly 8 includes a support frame 20, which is connected to the frame 1. The support frame 20 is equipped with a belt 21, and the belt 21 is equipped with an iron remover 22, which can effectively remove iron impurities from the slag and prevent iron impurities from entering the furnace.
[0034] A second guide plate 23 is provided on the front side of the support frame 20. The second guide plate 23 is located below the front end of the belt 21. After the iron impurities are separated from the belt 21, they fall onto the second guide plate 23 and slide down along the second guide plate 23, which facilitates the collection of iron impurities. The height limit plate 24 is connected to the support frame 20. The height limit plate 24 can scrape the slag on the conveyor belt 2 to prevent the slag from accumulating too high and affecting the adsorption of iron impurities in the slag by the iron separator 22.
[0035] In this invention, waste incineration slag enters the screening chamber 11 of the pre-screening assembly 9 through the feed inlet 17. The vibration motor 18 drives the inclined screen box 10 to vibrate, so that the slag is evenly distributed on the screen 13 and the screening is accelerated. Small-diameter slag enters the discharge chamber 12 through the screen 13 and is discharged from the second discharge port 16, falling directly onto the conveyor belt 2. Large-diameter slag is discharged from the first discharge port 14 and slides down along the first guide plate 15, which facilitates the subsequent collection and processing of large-volume slag.
[0036] After pre-screening, the slag moves to the right along the conveyor belt 2. When it passes the height limit plate 24 on the left side of the iron removal component 8, the height limit plate 24 scrapes the slag flat and controls its thickness. When the slag after passing through the height limit plate 24 enters the lower part of the iron removal component 8, the iron remover 22 adsorbs the iron impurities in the slag and separates them from the slag. The iron impurities are carried to the front end with the rotation of the belt 21. After leaving the belt 21, they fall onto the second guide plate 23 and slide down along the second guide plate 23, thus realizing the collection of iron impurities.
[0037] After iron removal, the slag continues to move along the conveyor belt 2 and reaches the sorting magnetic roller 4. The sorting magnetic roller 4 separates the copper, aluminum and other metals in the slag, separating them from the slag. The separated slag is then diverted through the distribution plate 5. The slag is discharged from the slag outlet 6, while the copper, aluminum and other metals are discharged from the aluminum outlet 7, thus realizing multi-stage slag sorting.
[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
