Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, and in particular to a metal sorting device for municipal solid waste incineration slag. Background Technology

[0002] With the popularization of municipal solid waste incineration technology, metal sorting of incinerator slag has become a key link in resource recycling. Common existing sorting technologies include:

[0003] Vibrating screening method: Separation is based on the difference in particle size of materials, but it is prone to screen clogging in sticky slag (containing molten metal particles).

[0004] Traditional electromagnetic chucks: Although they can attract metals by magnetic force, non-magnetic materials tend to accumulate on the adsorption surface, requiring manual cleaning and resulting in poor continuity.

[0005] Wet magnetic separation process: consumes a lot of water resources, and the wastewater generated requires secondary treatment, which does not conform to the trend of low-carbon treatment.

[0006] To address the aforementioned issues, an integrated dry magnetic separation system is proposed, which achieves efficient and continuous metal separation through the synergistic effect of electromagnetic matrix adsorption and dynamic cleaning. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies, which, although capable of magnetically adsorbing metals, tend to accumulate non-magnetic materials on the adsorption surface, requiring manual cleaning and resulting in poor continuity. Therefore, this invention proposes a metal sorting device for municipal solid waste incineration slag.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A metal sorting device for municipal solid waste incineration slag, comprising a conveyor;

[0010] A sorting mechanism for screening out metals is located above a conveyor. The sorting mechanism includes a mounting frame and an electromagnetic suction block. The mounting frame is located above the conveyor, and the electromagnetic suction block is fixedly installed inside the mounting frame. Rotary drums are rotatably installed on both sides inside the mounting frame, and the electromagnetic suction block is located between the two rotating drums. A first bracket is fixedly installed on both sides of the top of the mounting frame. An auxiliary rod is rotatably installed inside the first bracket. Pulleys are fixedly sleeved on the outer walls of the rotating drums and the outer walls of the auxiliary rods. The outer walls of the four pulleys are driven by the same belt.

[0011] A collection pipe is used to collect the discharged metal after screening, and the collection pipe is located on one side of the conveyor.

[0012] In one possible design, a mounting frame is provided above the conveyor, the mounting frame is fixedly installed inside the mounting frame, and the collecting pipe is fixedly installed on one side of the mounting frame.

[0013] In one possible design, a motor is fixedly mounted on the top of the mounting frame, and synchronous pulleys are fixedly sleeved on the outer wall of the motor output shaft and the outer wall of the rotating drum shaft, and the same synchronous belt is driven to be sleeved on the outer wall of the two synchronous pulleys.

[0014] In one possible design, the sorting mechanism further includes multiple scrapers, a third bracket is fixedly mounted on one side of the mounting frame, a rotating rod is rotatably mounted inside the third bracket, and multiple scrapers are fixedly mounted on the outer wall of the rotating rod, with multiple notches opened on the side of the scrapers.

[0015] In one possible design, the multiple scrapers are arranged in a ring at equal intervals.

[0016] In one possible design, bevel gears are fixedly fitted on the outer wall of the rotating rod and the outer wall of the rotating cylinder shaft, and the two bevel gears mesh with each other.

[0017] In one possible design, a second bracket is fixedly installed on one side of the bottom of the mounting frame. A rotating shaft is rotatably installed inside the second bracket. A brush cylinder is fixedly sleeved on the outer wall of the rotating shaft, and the brush cylinder cooperates with the outer wall of the belt.

[0018] In one possible design, a No. 1 gear is fixedly fitted on the outer wall of both the rotating shaft and the outer wall of the rotating cylinder shaft, and the two No. 1 gears mesh with each other.

[0019] In this application, during actual use, the incinerated and pulverized waste residue is transported by a conveyor. When passing under the electromagnetic suction block, the metal waste residue is adsorbed by the belt. The drive motor drives the drum to rotate via a synchronous pulley and synchronous belt. Then, the belt drives the belt to move the adsorbed metal waste residue towards one side of the collection pipe. When the waste residue detaches from the electromagnetic suction block, it falls into the collection pipe below. By placing a collection box at the bottom of the collection pipe, the metal can be sorted. When the drum is driven to rotate by the motor, the meshing bevel gear drives the rotating rod to rotate as well. The rotating rod drives multiple scrapers to rotate, thereby clearing the piles of waste residue on the conveyor and ensuring that the metal waste residue can be successfully adsorbed. When the drum rotates, the meshing first gear drives the rotating shaft to rotate. The rotating shaft drives the brush cylinder to rotate, and the brush cylinder helps to remove the waste residue from the surface of the belt.

[0020] In this utility model, a metal sorting device for municipal solid waste incineration slag can achieve continuous metal sorting by means of a sorting mechanism. When the incinerated and pulverized residue passes under the electromagnetic suction block, the metal waste inside will be adsorbed and then transported by belt to the inside of the collection pipe for collection.

[0021] In this utility model, the metal sorting device for municipal solid waste incineration slag can, through scraper and brush cylinder, not only separate the piles of waste slag so that the metal mixed inside can be better adsorbed, but also clean the surface of the conveyor belt, thereby avoiding the possibility of a lot of metal residue on the surface of the conveyor belt affecting subsequent adsorption.

[0022] In this invention, when the incinerated and pulverized waste residue is conveyed by a conveyor, it can work with a sorting mechanism to achieve continuous metal screening and collection. Furthermore, the multi-stage transmission enables the linkage of the rotating drum, scraper, and brush drum, allowing the cleaning of the device to be completed without manual intervention.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Reference Figure 1-2A metal sorting device includes: a conveyor 1, a sorting mechanism, and a collection pipe 3. The conveyor 1 uses a 800mm wide, 1.2m / s polyester canvas core rubber belt, driven by a variable frequency motor to ensure uniform material transport, and is used to uniformly transport incinerated slag to the sorting area. The sorting mechanism is installed inside a mounting frame 2 above the conveyor 1, and the mounting frame 2 is bolted to the support frame of the conveyor 1. The core component of the sorting mechanism is a metal adsorption assembly consisting of a mounting frame 4 and electromagnetic suction blocks 5. The mounting frame 4 is a 304 stainless steel rectangular frame structure, and the electromagnetic suction blocks 5 are fixed inside by brackets. The electromagnetic suction blocks 5 are made of a high magnetic permeability material. When metal waste approaches, the regularly arranged magnetic domains inside the suction blocks generate a strong magnetic field, thereby adsorbing the metal.

[0030] Inside the mounting frame 4, two rotating cylinders 7 are rotatably mounted. Each rotating cylinder 7 has a pulley fixedly fitted on its outer wall. Auxiliary rods 10 are rotatably mounted inside the two No. 1 brackets 11 located at the top of the mounting frame 4. The outer walls of the auxiliary rods 10 are also fixedly fitted with pulleys. The four pulleys form a linkage mechanism via an annular belt 9, which drives one of the rotating cylinders 7 to drive the belt 9 for transmission.

[0031] The drive system is powered by a motor 8 located at the top of the mounting frame 4. Both the output shaft of the motor 8 and the rotating shaft of the drum 7 are fitted with synchronous pulleys, which transmit power through a synchronous belt 6. When the motor 8 starts, it drives the drum 7 to rotate via the synchronous pulleys and the synchronous belt 6, thereby driving the belt 9 for transmission.

[0032] Specifically, the incinerated and pulverized waste residue is transported by conveyor 1. When it passes under the electromagnetic suction block 5, the metal waste residue will be adsorbed by the belt 9. The drive motor 8 drives the belt 9 to move the adsorbed metal waste residue to one side of the collection pipe 3. When the waste residue is detached from the electromagnetic suction block 5, it will fall into the collection pipe 3 below. By placing a collection box at the bottom of the collection pipe 3 for collection, the metal can be sorted.

[0033] Reference Figure 3 On one side of the metal collection end of the sorting mechanism, a third bracket 20 is fixed to one side of the mounting frame 4. A rotating rod 19 is rotatably installed inside the bracket. Scrapers 18 (made of nylon 66 injection molding) are evenly installed on the outer wall of the rotating rod 19 in a ring. A notch 17 is opened on the side of the scraper 18. The rotating rod 19 and the rotating drum 7 are connected by a bevel gear 16.

[0034] Specifically, when the rotating drum 7 is driven to rotate by the motor 8, the rotating rod 19 will be driven to rotate by the meshing bevel gear 16. The rotating rod 19 will drive multiple scrapers 18 to rotate, thereby clearing away the piles of waste residue on the conveyor 1, thus ensuring that the metal waste residue can be successfully adsorbed.

[0035] This application can be used in the field of waste incineration treatment, or in other fields applicable to this application.

[0036] Example 2

[0037] refer to Figure 3 An improvement upon Embodiment 1: A metal sorting device for municipal solid waste incineration slag, applied to the field of waste incineration treatment, includes a cleaning mechanism at the bottom of the mounting frame 4. A second bracket 13 is fixedly mounted on one side of the bottom of the mounting frame 4, with a rotating shaft 15 rotatably mounted inside. A brush cylinder 12 (made of PA6 nylon filament) is fixed to the outer wall of the rotating shaft 15, and the brush cylinder 12 contacts the outer wall of the circulating belt 9. The rotating shaft 15 and the rotating cylinder 7 are driven by a gear 14.

[0038] Specifically, when the drum 7 rotates, the meshing gear 14 will drive the shaft 15 to rotate, and the shaft 15 will drive the brush cylinder 12 to rotate. The brush cylinder 12 can help remove waste residue from the surface of the belt 9.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of the conveyor 1, the electromagnetic chuck 5, and the motor 8 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0040] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
