Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of slag recycling and screening, and in particular to a device for recycling and screening incinerator slag. Background Technology
[0002] A large amount of slag is generated during waste incineration. Incineration slag refers to the non-combustible material discharged from the tail end of the furnace bed, generally composed of inorganic substances, mainly metal oxides, hydroxides, carbonates, and silicates. It also contains large iron and aluminum containers and other metals that can be directly recycled. These magnetic metal materials usually need to be separated from the slag by screening devices. Currently, most slag screening devices on the market use magnets to adsorb slag powder. Metal materials are directly adsorbed onto the surface of the magnetic guide platform. However, with this magnetic adsorption method, the metal materials adhere to the surface of the adsorption mechanism, requiring manual scraping of the surface periodically. This is time-consuming and labor-intensive, and the recovery of metal materials is discontinuous, thus affecting the overall screening efficiency of the slag. Utility Model Content
[0003] To address the above shortcomings, this utility model proposes an incinerator slag recycling and screening device. It uses multiple rotating magnetic suction cylinders to adsorb metal materials mixed in the slag, and a scraper plate scrapes off the metal materials in a timely manner during the revolution of the magnetic suction cylinders, thereby improving the continuity of metal material recycling.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A slag recycling and screening device for incinerators includes: a housing with a cavity, an upper feed pipe and a collection box, a discharge port connected to the collection box, and an openable and closable discharge pipe at the lower part of the housing; multiple magnetic suction cylinders rotatably mounted on the housing, all connected to a drive mechanism that drives them to revolve relative to the housing; and a scraper plate located on the upper part of the housing, one end of which is tangent to the outer contour of the magnetic suction cylinders, and the other end of which is connected to the discharge port. The scraper plate is used to scrape off metal material from the outer peripheral wall of the magnetic suction cylinders.
[0006] The incinerator slag recycling and screening device according to the present invention has at least the following beneficial effects: In use, slag is fed into the cavity through the feed pipe, and then the drive mechanism drives multiple magnetic suction cylinders to revolve relative to the box body, so that the magnetic suction cylinders agitate the slag, which is conducive to the adsorption of metal materials mixed with the slag onto the magnetic suction cylinders. Finally, the magnetic suction cylinders rotate to the upper part of the box body, and the scraper plate abuts against the magnetic suction cylinders to scrape off the metal materials adsorbed onto the magnetic suction cylinders, so that the metal materials fall into the collection box for collection through the scraper plate, thereby reducing the previous manual scraping operation, which is conducive to improving the continuity of metal material recycling, and thus improving the screening efficiency of slag.
[0007] Furthermore, the drive mechanism includes two gear rings, which are respectively disposed on two opposite side walls of the housing. Each gear ring is concentrically provided with a drive gear, which is connected to a horizontally disposed first rotating shaft. The first rotating shaft is connected to a first motor that drives it to rotate. Each gear ring is meshed with multiple planetary gears, and each planetary gear meshes with the drive gear. Each magnetic suction cylinder is disposed between two planetary gears that are opposite each other in the horizontal direction.
[0008] Furthermore, the magnetic suction tube is connected between the two planetary gears via a second rotating shaft, and the inner wall of the housing is provided with a circular groove, which is engaged with the second rotating shaft.
[0009] Furthermore, the scraper includes a flat plate and an inclined plate connected to each other. The flat plate is located above the discharge port, and one side of the flat plate is tangent to the top of the outer contour of the magnetic cylinder's revolution. The lower end of the inclined plate is connected to the inner wall of the discharge port.
[0010] Furthermore, the flat plate and the inclined plate are connected by a circular arc plate, and the flat plate, the circular arc plate and the inclined plate are an integral structure.
[0011] Furthermore, the collection box is provided with a temporary storage chamber, and a filter plate is installed inside the temporary storage chamber. A collection bag is connected to the lower part of the temporary storage chamber, and the filter plate is used to separate the metal material in the upper part of the temporary storage chamber.
[0012] Furthermore, a second motor is provided on the side wall of the collection box, and a screw is connected to the output end of the second motor. The screw is located above the filter plate, and a slider is threadedly connected to the screw. The slider is connected to a pusher plate. A discharge port is provided on the side of the collection box away from the second motor, and the pusher plate is used to push the metal material toward the discharge port.
[0013] Furthermore, the collection box is provided with a guide plate, which is located below the filter plate. A pipe is installed at the lower end of the guide plate, and the collection bag is disposed on the installation pipe.
[0014] Furthermore, the box body is provided with four support rods, which are distributed in a rectangular shape on the lower end face of the box body.

[0026] See Figures 1 to 4 A slag recycling and screening device for incinerators includes: a housing 100, the housing 100 having a cavity 101, a feed pipe 110 and a collection box 120 at the upper part of the housing 100, a discharge port 102 connected to the collection box 120, and an openable and closable discharge pipe 130 at the lower part of the housing 100; multiple magnetic suction cylinders 200 rotatably mounted on the housing 100, the multiple magnetic suction cylinders 200 being connected to a drive mechanism that drives them to revolve relative to the housing 100; and a scraper 300 mounted on the upper part of the housing 100, one end of the scraper 300 being tangent to the outer contour of the magnetic suction cylinder 200, and the other end of the scraper 300 being connected to the discharge port 102, the scraper 300 being used to scrape off metal material from the outer peripheral wall of the magnetic suction cylinder 200.
[0027] In the above-described incinerator slag recovery and screening device, slag is fed into the chamber 101 through the feed pipe 110. Then, the drive mechanism drives multiple magnetic suction cylinders 200 to revolve relative to the box 100, causing the magnetic suction cylinders 200 to stir the slag. This facilitates the adsorption of metal materials mixed with the slag onto the magnetic suction cylinders 200. Finally, the magnetic suction cylinders 200 rotate to the upper part of the box 100, and the scraper 300 abuts against the magnetic suction cylinders 200 to scrape off the metal materials adsorbed on the magnetic suction cylinders 200. The metal materials fall into the collection box 120 for collection through the scraper 300, thereby reducing the previous manual scraping operation, improving the continuity of metal material recovery, and thus improving the slag screening efficiency.
[0028] It is understandable that the scraper 300 extends along the tangential direction of the outer contour of the magnetic cylinder 200's revolution. As the magnetic cylinder 200 passes the scraper 300, the scraper 300 scrapes off metal material from the outer peripheral wall of the magnetic cylinder 200, and this metal material is continuously pushed onto the scraper 300 as the magnetic cylinder 200 rotates. Furthermore, based on the contact area between the scraper 300 and the actual magnetic cylinder, multiple scraper 300s can be arranged along the outer contour of the magnetic cylinder 200's revolution, thereby utilizing different scraper 300s to scrape off metal material from different outer peripheral walls of the magnetic cylinder 200.
[0029] See Figures 1 to 3 Furthermore, the drive mechanism includes two gear rings 210, which are respectively disposed on two opposite side walls of the housing 100. Each gear ring 210 is concentrically provided with a drive gear 220, which is connected to a horizontally disposed first rotating shaft 221. The first rotating shaft 221 is connected to a first motor 222 that drives its rotation. Each gear ring 210 is meshed with multiple planetary gears 230, and each planetary gear 230 meshes with the drive gear 220. Each magnetic cylinder 200 is disposed between two horizontally opposite planetary gears 230. Specifically, the first motor 222 drives the first rotating shaft 221 to rotate, causing the drive gear 220 to drive the multiple planetary gears 230 to revolve and rotate along the inner wall of the gear ring 210. The planetary gear 230 rotates relative to the driving gear 220, causing the magnetic suction cylinder 200 to continuously rotate around its axis. This facilitates full contact between the outer peripheral wall of the magnetic suction cylinder 200 and the slag, allowing the outer peripheral wall of the magnetic suction cylinder 200 to adsorb more metal material. The planetary gear 230 also revolves relative to the driving gear 220, enabling the magnetic suction cylinder 200 to rotate until it comes into contact with the scraper plate 300, which helps the scraper plate 300 to scrape off the metal material from the outer peripheral wall of the magnetic suction cylinder 200. It is understood that the outer peripheral wall of the first rotating shaft 221 is equipped with multiple stirring plates 223, which further agitate the slag.
[0030] See Figures 1 to 3Furthermore, the magnetic suction cylinder 200 is connected between the two planetary gears 230 via a second rotating shaft 201. The inner wall of the housing 100 is provided with a circular groove, which engages with the second rotating shaft 201. This circular groove guides and limits the movement of the planetary gears 230, facilitating their revolution relative to the driving gear 220. It is understood that the gear ring 210 is bolted to the inner wall of the housing 100, and the housing 100 has mounting holes for the first rotating shaft 221 to insert, thus facilitating the installation of the gear ring 210 and the driving gear 220.
[0031] See Figures 1 to 3 Furthermore, the scraper 300 includes a flat plate 301 and an inclined plate 302 connected to each other. The flat plate 301 is located above the discharge port 102, and one side of the flat plate 301 is tangent to the top of the outer contour of the magnetic suction cylinder 200. The lower end of the inclined plate 302 is connected to the inner wall of the discharge port 102. Specifically, as metal material is continuously scraped off one side of the flat plate 301, the metal material is continuously pushed to the flat plate 301 by the rotation of the magnetic suction cylinder 200. Then, the metal material moves towards the discharge port 102 through the inclined plate 302, thereby shortening the time for the metal material to fall into the collection box 120 by utilizing the inclined plate 302, which is beneficial to improving the collection efficiency of the metal material.
[0032] See Figure 3 Furthermore, the flat plate 301 and the inclined plate 302 are connected by an arc plate 303, which facilitates the metal material to fall more effectively onto the inclined plate 302. The flat plate 301, the arc plate 303, and the inclined plate 302 are an integral structure. The flat plate 301, the arc plate 303, and the inclined plate 302 can be molded together by injection molding or fixed together by welding, which helps to improve the structural strength of the scraper plate 300. It is understood that the side of the flat plate 301 away from the discharge port 102 has an inclined scraper surface, which helps to accelerate the scraping of metal material by the flat plate 301.
[0033] See Figure 1 and Figure 4 Furthermore, the collection box 120 is provided with a temporary storage chamber 121, and a filter plate 122 is provided inside the temporary storage chamber 121. A collection bag is connected to the lower part of the temporary storage chamber 121. The filter plate 122 is used to separate the metal material in the upper part of the temporary storage chamber 121, thereby using the filter plate 122 to separate the metal material and using the collection bag to collect small particulate impurities such as dust mixed with the metal material.
[0034] See Figure 1 and Figure 4Furthermore, a second motor 123 is installed on the side wall of the collection box 120. The output end of the second motor 123 is connected to a screw 124, which is located above the filter plate 122. A slider 125 is threadedly connected to the screw 124, and a pusher plate 126 is connected to the slider 125. A discharge port is located on the side of the collection box 120 away from the second motor 123. The pusher plate 126 is used to push the metal material towards the discharge port. Specifically, when metal material needs to be discharged, the first motor 222 is stopped, and the second motor 123 is started, causing the screw 124 to rotate continuously. This causes the slider 125 to move the pusher plate 126 under the action of the screw thread. Ultimately, the pusher plate 126 continuously pushes the metal material on the filter plate 122 to the discharge port, facilitating the discharge of the filtered metal material. After the metal material is discharged, the second motor 123 reverses, allowing the pusher plate 126 to return to its initial position. Understandably, the lower end of the pusher plate 126 is provided with bristles to facilitate cleaning of the filter plate 122 during the movement of the pusher plate 126. In addition, in order to facilitate the sealing of the discharge pipe 130 and the discharge port, the collection box 120 is provided with a discharge pipe connected to the discharge port. Both the discharge pipe and the discharge pipe 130 are provided with sealing plates, and the discharge pipe and the discharge pipe 130 are provided with through holes for the sealing plates to be inserted and removed.
[0035] See Figure 1 and Figure 4 Furthermore, the collection box 120 is provided with a guide plate 127, which is located below the filter plate 122. The lower end of the guide plate 127 is equipped with a pipe 128, and the collection bag is installed in the pipe 128, thereby guiding the falling dust and other small particles of debris, which is conducive to accelerating the collection of small particles of debris.
[0036] See Figure 1 and Figure 4 Furthermore, the box 100 is provided with four support rods 140, which are rectangularly distributed on the lower end face of the box 100, thereby improving the stability of the box 100 when placed.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
