Description
Technical Field
[0001] This utility model belongs to the technical field of aluminum ash sorting equipment, and in particular relates to an aluminum ash gradient sorting and recycling device. Background Technology
[0002] Aluminum ash is a waste product generated during the aluminum industry. It contains metallic aluminum, alumina, and other impurities. Effective sorting and recycling of aluminum ash can not only improve resource utilization but also reduce environmental pollution. Screening devices are generally used for screening, but their use has the following shortcomings:
[0003] 1. Some existing screening equipment can only screen a single particle size and cannot achieve gradient separation of different particle size components in aluminum ash. This results in the aluminum ash still containing a lot of impurities after screening, which affects the subsequent recycling and utilization effect. Specifically, coarse screens are used to separate large particles of metallic aluminum, but cannot further separate fine particles of metallic aluminum or oxides. While fine screens can intercept fine particles, they are prone to clogging, affecting screening efficiency.
[0004] Therefore, we propose an aluminum ash gradient sorting and recycling device. Utility Model Content
[0005] The purpose of this invention is to address the problem that existing screening equipment can only screen for single particle sizes and cannot achieve gradient separation of different particle sizes in aluminum ash. This results in aluminum ash still containing a lot of impurities after screening, affecting subsequent recycling and utilization. Specifically, coarse screens are used to separate large particles of metallic aluminum, but cannot further separate fine particles of metallic aluminum or oxides. While fine screens can intercept fine particles, they are prone to clogging, affecting screening efficiency. Therefore, this invention proposes an aluminum ash gradient sorting and recycling device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An aluminum ash gradient sorting and recycling device includes:
[0008] A support frame is provided, and a screening component is provided in the middle of the support frame. The screening component includes a screen box installed in the middle of the support frame. A coarse screen and a fine screen are fixedly connected to the upper end and the middle part of the screen box, respectively. The upper coarse screen separates coarse particles of metallic aluminum in aluminum ash, and the middle fine screen is used to intercept fine particles of oxide. A guide plate is fixedly connected to the lower end of the screen box to discharge the mixture filtered by the fine screen.
[0009] The magnetic separation assembly includes a magnetic separator cylinder installed at the lower end of a support frame. An outer cylinder is located inside the magnetic separator cylinder, and neodymium iron boron (NdFeB) magnetic blocks are installed inside the outer cylinder. A metal aluminum particle outlet is located at the front end of the magnetic separator cylinder, and a ferromagnetic impurity outlet is located at the lower end. The mixture filtered through a fine screen flows into the outer wall of the outer cylinder through the inlet of the magnetic separator cylinder. When the outer cylinder rotates, the magnetic attraction of the NdFeB magnetic blocks attracts the magnetic metal to the outer wall of the outer cylinder. As the outer cylinder rotates to the non-magnetic zone, the magnetic metal automatically falls off and is discharged from the ferromagnetic impurity outlet. The metal aluminum particles, being non-magnetic, are directly discharged from the metal aluminum particle outlet at the front end of the outer cylinder due to gravity.
[0010] In one possible design, a conveying pipe is fixedly connected to the upper end of the support frame, and an auger is rotatably connected inside the conveying pipe. A second servo motor is fixedly connected to the outer wall of the rear end of the conveying pipe, and the output end of the second servo motor passes through the conveying pipe and is fixedly connected to the auger. A feed hopper is fixedly connected to the upper part of the rear end of the conveying pipe, and aluminum ash raw material is added from the feed hopper. The second servo motor starts and drives the auger to rotate to convey the aluminum ash raw material, which can prevent the aluminum ash raw material from clumping and clogging. Silicone materials are sleeved on the lower end of the discharge port of the conveying pipe and the upper end of the feed port of the screen box. The silicone connecting hose has retaining rings at both its upper and lower ends. These retaining rings are used to securely seal the silicone connecting hose to the outlet of the conveying pipe and the inlet of the screen box using bolts. The vibration of the screen box during operation will not affect the conveying by the auger. T-shaped rotating shafts are rotatably connected to the upper and middle parts of the front end of the inner wall of the screen box. Rubber elastic balls are fixedly connected to the rear ends of the two T-shaped rotating shafts. When the screen box vibrates, it causes the rubber elastic balls to bounce on the upper part of the fine screen and the guide plate, which facilitates the discharge of the screened aluminum ash and prevents blockage.
[0011] In one possible design, a vibrating motor is fixedly connected to the lower end of both sides of the outer wall of the screen box, and spring shock absorbers are fixedly connected to the four corners of the screen box. The lower end of the spring shock absorber is fixedly connected to the middle of the support frame. The vibrating motor drives the screen box to vibrate to screen the aluminum ash. The upper and middle parts of the rear outer wall of the screen box are respectively fixedly connected to a first discharge pipe and a second discharge pipe by bolts. The lower part of the rear outer wall of the screen box is fixedly connected to a discharge frame by bolts. The first discharge pipe and the second discharge pipe are respectively located on the coarse screen. The discharge ports corresponding to the mesh and fine screen are provided. The discharge frame is located at the discharge port corresponding to the guide plate. A second connecting hose is fixedly connected to one side of the lower end of the first discharge pipe and the second discharge pipe. A first connecting hose is fixedly connected to the lower end of the discharge frame. The magnetic separator is fixedly connected to the discharge port of aluminum particles. A first guide trough is fixedly connected to the lower end of the discharge port of aluminum particles. The magnetic separator is fixedly connected to the discharge port of ferromagnetic impurities. A second guide trough is fixedly connected to the lower end of the discharge port of ferromagnetic impurities, which is used to transport the sorted aluminum ash.
[0012] In one possible design, support plates are fixedly connected to both sides of the lower end of the support frame. The magnetic separator is fixedly installed in the middle of the upper part of the two support plates. The outer cylinder inside the magnetic separator is rotatably connected to the support plate. The neodymium iron boron magnets inside the outer cylinder are fixedly connected to the support frame. A first servo motor is fixedly connected to the outer wall of the upper part of the support plate. The output end of the first servo motor passes through the support plate and is fixedly connected to the outer cylinder. The outer cylinder is made of rotating non-magnetic stainless steel, and the neodymium iron boron magnets are distributed in a fan shape. The first servo motor drives the outer cylinder to rotate.
[0013] In one possible design, a third mounting frame is fixedly connected to both sides of the lower rear end of the support frame. A collection box is slidably connected inside the third mounting frame. The lower ends of the two second connecting hoses are fixedly connected to the feed inlet of the third collection frame. The coarse aluminum particles separated by the upper coarse screen and the fine oxide particles screened by the middle fine screen are discharged from the first discharge pipe and the second discharge pipe, respectively, and discharged into the two collection boxes through the fixedly connected second connecting hoses.
[0014] In one possible design, a first mounting frame is fixedly connected to the front end of the lower part of the support frame, and a recycling bin is slidably connected inside the first mounting frame. A second mounting frame is fixedly connected to the rear end of the lower part of the support frame, and a waste bin is slidably connected inside the second mounting frame. The lower end of the first connecting hose is fixedly connected to the feed inlet of the magnetic separator. The lower end of the first guide chute is fixedly connected to the feed inlet of the first mounting frame. The lower end of the second guide chute is fixedly connected to the feed inlet of the second mounting frame. The mixed material discharged from the guide plate is discharged into the magnetic separator through the discharge frame and the first connecting hose. Magnetic metals are discharged from the ferromagnetic impurity discharge port and discharged into the waste bin through the second guide chute. Since aluminum particles are non-magnetic, they are directly discharged from the aluminum particle discharge port at the front end of the outer cylinder under the action of gravity and discharged into the recycling bin through the first guide chute.
[0015] In this application, during use, aluminum ash raw material first enters the conveying pipe through the feed hopper. A auger driven by a second servo motor evenly conveys the raw material to the screen box, preventing aluminum ash from clumping. A silicone connecting hose connects the conveying pipe and the screen box, sealed with a snap ring to reduce the impact of screen box vibration on the conveying process. A vibration motor drives the screen box to vibrate. The coarse screen separates large particles of metallic aluminum, which are discharged into a collection box through the first discharge pipe and the second connecting hose. The fine screen intercepts fine oxide particles, which are discharged into another collection box through the second discharge pipe. The mixture that does not pass through the fine screen is guided by a guide plate to a magnetic field. In the magnetic separator, rubber elastic balls continuously strike the screen and guide plate during vibration to prevent material blockage. After the mixture enters the magnetic separator, the first servo motor drives the outer cylinder to rotate. Neodymium iron boron magnets adsorb ferromagnetic impurities to the surface of the outer cylinder. After rotating to the non-magnetic zone, the impurities are discharged from the ferromagnetic impurity outlet into the waste bin. Non-magnetic aluminum particles directly enter the recycling bin through the aluminum particle outlet via the first guide chute. The sorted coarse aluminum particles, fine oxide particles, aluminum particles, and ferromagnetic impurities enter the corresponding collection bins or waste bins, achieving efficient resource recovery and environmentally friendly treatment.
[0016] In this invention, an aluminum ash gradient sorting and recycling device is described. By setting coarse and fine screens, it achieves gradient separation of different particle size components in aluminum ash. The coarse screen can separate large particles of metallic aluminum, while the fine screen further intercepts fine oxide particles, thereby improving the purity of the aluminum ash after screening and providing better raw materials for subsequent recycling and utilization. Rubber elastic balls are set at the front end of the inner wall of the screen box. When the screen box vibrates, the rubber elastic balls will bounce on the upper part of the fine screen and the guide plate, which helps to prevent screen blockage and ensures smooth screening.
[0017] In this utility model, the aluminum ash gradient sorting and recycling device uses an auger inside the conveying pipe, which is driven to rotate by a second servo motor. This can effectively prevent the aluminum ash raw material from clumping and blocking, and improve the conveying efficiency. By setting up a magnetic separation component, the metal impurities in the aluminum ash can be screened out. The modular design of the collection box, recycling box and waste box facilitates the classification and recycling of metallic aluminum, oxides and impurities. Attached Figure Description

A metal aluminum particle outlet 17 is provided at the front end of the magnetic separator 14, and a ferromagnetic impurity outlet 19 is provided at the lower end of the magnetic separator 14. The mixture filtered by the fine screen 6 flows into the outer wall of the outer cylinder 15 through the feed inlet of the magnetic separator 14.
