Description

Technical Field

[0001] This utility model relates to the field of metal recycling technology, and in particular to a non-ferrous metal smelting waste slag sorting and recycling device. Background Technology

[0002] With the continuous development of non-ferrous metal smelting technology, the amount of waste slag generated during the smelting process is constantly increasing. This waste slag contains valuable metallic elements such as copper, lead, zinc, and aluminum, as well as other harmful substances. If not effectively recycled, this waste slag will waste resources and harm the environment. Existing non-ferrous metal smelting waste slag sorting and recycling devices mostly rely on traditional physical sorting methods such as magnetic separation and flotation.

[0003] A search revealed that Chinese patent application CN118649779B discloses a non-ferrous metal smelting waste slag sorting and recycling device, which mainly uses a first connecting membrane and a blower to perform secondary air separation on heavier particles.

[0004] Compared with existing technologies in related fields, it can be seen that due to the complex composition and uneven particle size distribution of waste residue, the accumulation of waste residue materials of different particle sizes in one place for air classification and recycling often leads to unsatisfactory recycling results and increases the waste of resources. Utility Model Content

[0005] The purpose of this invention is to provide a non-ferrous metal smelting waste slag sorting and recycling device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A non-ferrous metal smelting waste slag sorting and recycling device includes a casing, a feed pipe installed on the upper surface of the casing, a screening unit, a support frame and a guiding unit installed inside the casing, and a feeding unit and an air separation unit installed on the support frame.

[0008] The screening unit inside the housing includes an elastic base and a screen. The elastic base is installed inside the housing and a mounting frame is installed on the elastic base. A vibration motor is installed on the lower surface of the mounting frame. The screen is arranged in an inclined manner in the mounting frame with an upper and lower structure. The screen is located below the feed pipe, and the screen holes of the screen decrease in size from top to bottom.

[0009] The air separation unit includes air guide pipes arranged on a support frame, located below the screen, with connecting valves installed at the ends of the air guide pipes and air outlets arranged on the sides of the air guide pipes.

[0010] Furthermore, the air duct is wider at one end and narrower at the other, with its internal diameter gradually decreasing from the end closest to the connecting valve.

[0011] Furthermore, the feeding unit on the support frame includes a rotating shaft, a drive assembly is mounted on the support frame, the rotating shafts are arranged on the support frame, the rotating shafts are connected to the drive assembly, and a toothed roller is mounted on the rotating shaft, the toothed roller being located above the screen.

[0012] Furthermore, the drive components on the support frame include a rotary motor and a pulley mechanism. The rotary motor is mounted on the support frame, and the pulley mechanism is rotatably mounted on the support frame. The pulley mechanism connects the output shaft and the rotating shaft of the rotary motor.

[0013] Furthermore, the material guiding unit inside the housing includes a first placement frame and a second placement frame. The first placement frame is arranged in an upper and lower structure inside the housing, and the first placement frame and the screen are at corresponding heights. Placement slots are arranged on the first placement frame, and a first conveyor belt mechanism is installed in the placement slots. The second placement frame is installed inside the housing, and the second placement frame is located below the first placement frame. A second conveyor belt mechanism is installed on the second placement frame, and the lower surface of the second conveyor belt mechanism is at the same height as the mounting frame.

[0017] 1. By sieving waste materials according to particle size through an array of screens, the air volume of the air separator in the air guide pipe and air outlet can be adjusted according to the particle size of the waste materials. This enables precise sorting of waste materials of different particle sizes, allowing different waste materials to be separated quickly, effectively improving the efficiency and quality of sorting and recycling, and reducing resource waste.

[0018] 2. The rotating shaft and toothed roller are driven to rotate by a rotating motor and pulley mechanism.

[0033] like Figures 1-11 As shown, a non-ferrous metal smelting waste slag sorting and recycling device includes a casing 1. A feed pipe 2 is installed on the upper surface of the casing 1. A screening unit, a support frame 11, and a guiding unit are installed inside the casing 1. A material-pulling unit and an air-separating unit are installed on the support frame 11. The waste slag material to be sorted and recycled is transported to the screening unit inside the casing 1 through the feed pipe 2. The screening unit separates the waste slag material according to its particle size. The air volume of the air-separating unit is controlled according to the particle size of the waste slag material. The air-separating unit accurately sorts the waste slag material of different particle sizes. During the sorting process, the material-pulling unit moves the material on the screening unit to prevent the material from accumulating and affecting the sorting effect, thereby improving the sorting quality.

[0034] like Figures 2-5 , Figure 7 As shown, the screening unit inside the housing 1 includes an elastic base 301 and a screen 304. The elastic base 301 is installed inside the housing 1, and a mounting frame 303 is mounted on the elastic base 301. A vibration motor 302 is mounted on the lower surface of the mounting frame 303. The screen 304 is arranged in an inclined vertical structure inside the mounting frame 303, located below the feed pipe 2. The screen openings of the screen 304 decrease in size from top to bottom. The waste material conveyed to the housing 1 by the feed pipe 2 falls onto the screen 304, where it is screened to separate the waste material according to its particle size. Waste materials of different sizes remain on the screen 304 at different heights. On screen 304, fine waste materials that cannot be air-separated fall into the lower part of the mounting frame 303, which facilitates the control of the air volume during air separation according to the particle size, achieving precise separation of waste materials, effectively improving the efficiency of waste material separation and recycling, and reducing resource waste. During the process of screening waste materials, the vibrating motor 302 and the elastic base 301 work together to vibrate the mounting frame 303 and the screen 304, so that the screen 304 can better screen the waste materials, enabling waste materials of different particle sizes to be separated quickly, improving the efficiency of separation and recycling, and the vibration causes the waste materials on the screen 304 to move on the screen 304.

[0035] like Figure 3 , Figure 5 , Figure 11 As shown, the air separation unit includes an air guide pipe 402, which is arranged on the support frame 11 and located below the screen 304. A connecting valve 401 is installed at the end of the air guide pipe 402, and air outlets 403 are arranged on the side of the air guide pipe 402. An external blower delivers air into the air guide pipe 402 through the connecting valve 401 and sprays it out through the air outlets 403, thereby performing air separation on the waste material screened by the screen 304.

[0036] like Figure 11 As shown, the air guide pipe 402 is wide at one end and narrow at the other. The internal diameter of the air guide pipe 402 gradually decreases from the end near the connecting valve 401. The airflow velocity is slow in the wide pipe and fast in the narrow pipe. The design of the air guide pipe 402 being wide at one end and narrow at the other ensures that the airflow entering the air guide pipe 402 is evenly distributed, thus ensuring the uniformity of the airflow ejected from the air outlet 403.

[0037] like Figure 3 , Figures 5-7 As shown, the material feeding unit on the support frame 11 includes a rotating shaft 503. A drive assembly is installed on the support frame 11. The rotating shaft 503 is arranged on the support frame 11 and is connected to the drive assembly. A toothed roller 504 is installed on the rotating shaft 503. The toothed roller 504 is located above the screen 304. The toothed roller 504 blocks the waste material on the screen 304 and drives the rotating shaft 503 and the toothed roller 504 to rotate through the drive assembly. The toothed roller 504 moves and knocks the waste material on the screen 304, so that the material is dispersed, avoiding the material from accumulating together and affecting the sorting of waste material, thus improving the sorting efficiency.

[0038] like Figure 6 , Figure 7 , Figure 9 As shown, the drive assembly on the support frame 11 includes a rotary motor 501 and a pulley mechanism 502. The rotary motor 501 is mounted on the support frame 11, and the pulley mechanism 502 is rotatably mounted on the support frame 11. The pulley mechanism 502 connects the output shaft of the rotary motor 501 and the rotating shaft 503. The rotary motor 501 drives the pulley mechanism 502 to rotate, and the pulley mechanism 502 drives the rotating shaft 503 at different heights to rotate.

[0039] like Figure 2 , Figure 4 , Figure 7 , Figure 8As shown, the material guiding unit inside the housing 1 includes a first placement frame 601 and a second placement frame 604. The first placement frame 601 is arranged vertically inside the housing 1, with the first placement frame 601 and the screen 304 at corresponding heights. Placement slots 603 are arranged on the first placement frame 601, and a first conveyor belt mechanism 602 is installed in the placement slots 603. The second placement frame 604 is installed inside the housing 1, located below the first placement frame 601, and a second conveyor belt mechanism 605 is installed on the second placement frame 604. The lower surfaces of the second conveyor belt mechanism 605 and the mounting frame 303 are at the same height. Waste materials sorted on screens 304 at different heights fall onto the first conveyor belt mechanism 602 at the same height but different positions. The first conveyor belt mechanism 602 discharges and collects the sorted waste materials. Fine waste materials that cannot be air-separated at the lower end of the mounting frame 303 fall onto the second conveyor belt mechanism 605. The second conveyor belt mechanism 605 discharges and collects the fine waste materials, effectively improving the convenience of discharging and collecting the sorted waste materials.

[0040] like Figure 1 , Figure 4 , Figure 7 , Figure 8 , Figure 10 As shown, the side of the casing 1 is provided with a first discharge pipe 7 and a second discharge pipe 8. The second discharge pipes 8 are arranged in a row. The first discharge pipe 7 is connected to the second conveyor belt mechanism 605, and the second discharge pipe 8 is connected to the first conveyor belt mechanism 602. During the sorting process, the materials on the first conveyor belt mechanism 602 at different positions enter the corresponding second discharge pipes 8. Different waste materials on the first conveyor belt mechanism 602 are discharged and collected through the second discharge pipes 8, and the fine waste materials on the second conveyor belt mechanism 605 are discharged and collected through the first discharge pipe 7. The waste materials and fine waste materials separated by air separation are discharged and collected separately through the first discharge pipe 7 and the second discharge pipe 8, which facilitates the corresponding processing of different waste materials and effectively improves the convenience of collecting the sorted waste materials.

[0041] like Figure 4 , Figure 10 As shown, an observation window 9 is provided on the side of the casing 1, and a transparent plate 10 is installed inside the observation window 9. The observation window 9 and the transparent plate 10 facilitate the observation of the sorting situation inside the casing 1, and make it easy to keep track of the working status of waste material sorting and recycling.

[0042] Working principle: such as Figures 1-8As shown, the waste material to be sorted and recycled is conveyed into the machine casing 1 through the feed pipe 2. The waste material entering the machine casing 1 falls onto the screen 304, and the screen 304 screens the waste material, separating it according to particle size. Waste material of different particle sizes remains on the screen 304 at different heights. Fine waste material that cannot be air-separated falls into the lower part of the mounting frame 303. During the screening process of the screen 304, the vibration motor 302 and the elastic base 301 work together to vibrate the mounting frame 303 and the screen 304, so that the screen 304 can better screen the waste material and make the waste material move on the screen 304.

[0043] like Figure 3 , Figures 5-7 , Figure 9 As shown, when the waste material on the screen 304 moves with the vibration of the screen 304, the rotary motor 501 drives the pulley mechanism 502 to rotate, the pulley mechanism 502 drives the rotating shaft 503 at different heights to rotate, the rotating shaft 503 drives the toothed roller 504 to rotate, and the toothed roller 504 moves and knocks the waste material on the screen 304, so that the material is dispersed and avoids the material from piling up together;

[0044] like Figure 3 , Figure 5 , Figure 11 As shown, the external blower delivers air to the air duct 402 through the connecting valve 401 and sprays it out through the air outlet 403, thereby blowing the waste residue material screened by the screen 304 to complete the air separation of the waste residue material.

[0045] like Figure 2 , Figure 4 , Figure 7 , Figure 8 , Figure 10 As shown, waste materials sorted on screens 304 at different heights fall onto the first conveyor belt mechanism 602 at the same height but different positions. The first conveyor belt mechanism 602 transports the sorted waste materials to the second discharge pipe 8. The second discharge pipe 8 discharges and collects the separated waste materials. Fine waste materials that cannot be air-separated at the lower end of the mounting frame 303 fall onto the second conveyor belt mechanism 605. The second conveyor belt mechanism 605 discharges the fine waste materials to the first discharge pipe 7. The first discharge pipe 7 discharges and collects the fine waste materials.

[0046] like Figure 4 , Figure 10 As shown, the observation window 9 and the transparent plate 10 facilitate the observation of the sorting situation inside the casing 1, and make it easy to keep track of the working status of waste material sorting and recycling.
