Description

Technical Field

[0001] This utility model relates to the field of waste metal mixture sorting technology, specifically to a combined separation device for waste metal mixtures. Background Technology

[0002] The significance of metal sorting in mixed waste metals lies in improving resource recovery rates, reducing environmental pollution, lowering labor costs and environmental burden, and promoting the sustainable development of the metal recycling industry. Traditional sorting methods have the following shortcomings:

[0003] Firstly, traditional sorting methods have a limited coverage, generally only suitable for sorting two or three types of materials.

[0004] Secondly, the separation rate of traditional sorting methods is not good;

[0005] Third, the sorting sequence design of traditional sorting methods is not reasonable enough, which is not conducive to saving energy and costs, nor to improving the separation rate. Utility Model Content

[0006] The purpose of this invention is to provide a combined separation device for waste mixtures that has a wide coverage, can be applied to the treatment and sorting of waste mixtures in multiple industries, and has a reasonable arrangement of sorting sequence, which is conducive to improving the separation rate, reducing equipment power configuration, and saving energy and costs.

[0007] The technical solution of this utility model is:

[0008] A combined separation device for waste mixtures, comprising:

[0009] Rinse tank and first conveyor;

[0010] The first conveyor transports the material from the bottom of the rinsing tank to the dewatering machine;

[0011] The polishing machine is a machine that inputs material from a dewatering machine. The polishing machine includes a main outlet and a buffer hopper at the main outlet.

[0012] Magnetic separator, including magnetic material outlet and non-magnetic material outlet, and material input magnetic separator with buffer hopper output;

[0013] Eddy current separator, including non-ferrous metal outlet and non-ferrous metal outlet, the material output from non-magnetic material outlet enters the eddy current separator;

[0014] The material exiting the non-ferrous metal outlet enters the color sorter. The specific operation of a combined separation device for waste and mixed materials in this scheme is as follows:

[0015] The waste mixture is fed into a rinsing tank, where floating debris (including lightweight plastics, dust, and wood blocks) floats to the top, while the remaining settling materials (including both metallic and non-metallic materials) sink, thus separating the floating debris from the settling materials. The rinsing tank washes out the floating debris such as lightweight plastics, dust, and wood blocks, which are then sent to a floating debris storage bin. The remaining settling material is conveyed from the bottom of the rinsing tank to a dewatering machine via a first conveyor for dewatering.

[0016] After dehydration, the material is fed into a polishing machine for polishing. The polishing machine removes contaminated materials and those that have lost their metallic color due to surface oxidation, restoring the original metallic color through friction and collision. This facilitates higher-quality metal separation by subsequent color sorting equipment. Because the polishing machine operates intermittently, which does not match the frequency of subsequent continuous operation equipment, a buffer hopper is installed at the main outlet of the polishing machine in this design. The polished material is fed into the buffer hopper.

[0017] The material output from the buffer silo is fed into the magnetic separator. The magnetic separator first separates the ferromagnetic materials, which are then discharged through the magnetic material outlet and transported to a designated location. The remaining material after iron removal is discharged through the non-magnetic material outlet, thus completing the separation of ferromagnetic materials from the rest of the material.

[0018] The material output from the non-magnetic material outlet of the magnetic separator enters the eddy current separator. The eddy current separator is mainly used for separating non-ferrous metal materials from non-ferrous metal materials. The separator separates non-ferrous metals (including stainless steel and washed sediment, etc.) and outputs them through the non-ferrous metal outlet, which is then transported to a designated location. Non-ferrous metal materials (including copper, aluminum, lead, zinc, etc.) are output through the non-ferrous metal outlet, thus completing the separation of non-ferrous metal materials from non-ferrous metal materials.

[0019] The non-ferrous metal material output from the eddy current separator enters a color sorter, which separates the copper material with obvious color differences, thus completing the separation of copper from the other non-ferrous metal materials. Compared with traditional sorting methods, the combined separation equipment in this solution has the following advantages:

[0020] Firstly, the combined separation equipment in this solution has a wide coverage and can be applied to the treatment and sorting of waste mixtures in multiple industries (including environmental protection, metallurgy, building materials, ports, slag, etc.), completing the separation of multiple materials in one go.

[0021] Secondly, the combined separation equipment in this solution uses different sorting equipment to separate materials based on differences in density, properties, and magnetism, thereby improving the separation rate. At the same time, it fully considers the characteristics, proportions, and prices of the required sorting equipment, and rationally arranges the types and order of sorting equipment. Materials with a large proportion are sorted out first, while those with a small proportion are sorted out in subsequent processes. Low-value equipment is configured in the front stage, and high-value equipment is configured in the back stage. By rationally arranging the sorting sequence, it is beneficial to improve the separation rate, reduce equipment power requirements, and save energy and costs.

[0022] As a preferred option, it also includes:

[0023] X-ray sorting machine, color sorting machine includes a first outlet and a second outlet of color sorting machine. The material output from the second outlet of color sorting machine enters the X-ray sorting machine. X-ray sorting machine includes a first outlet and a second outlet of X-ray sorting machine.

[0024] The material output from the second outlet of the X-ray sorter enters the fluorescence sorter. The color sorter separates copper materials with obvious color differences. The copper materials are output through the first outlet of the color sorter, while the other non-ferrous metal materials are output through the second outlet, thus completing the separation of copper materials from the other non-ferrous metal materials.

[0025] The non-ferrous metal material output from the second outlet of the color sorter enters the X-ray separator. The X-ray separator separates aluminum material and lead-zinc material with large density differences. The aluminum material is output through the first outlet of the X-ray separator, and the lead-zinc material is output through the second outlet of the X-ray separator, thus completing the separation of aluminum material from the remaining lead-zinc material.

[0026] Lead and zinc materials output from the second outlet of the X-ray separator enter the fluorescence separator. The fluorescence separator separates the lead and zinc materials according to the difference in the wavelength of the materials, and the materials fall into the lead material bin and the zinc material bin respectively, thus completing the separation of lead and zinc materials.

[0027] As a preferred option, it also includes:

[0028] The fifth conveyor transports the material output from the second outlet of the X-ray separator to the fluorescence separator. Preferably, it also includes:

[0029] The material output from the dewatering machine is conveyed to the polishing machine via the second conveyor.

[0030] The material from the buffer silo is transported to the magnetic separator via the third conveyor.

[0031] The fourth conveyor transports the non-ferrous metals from the outlet to the color sorter.

[0032] As a preferred option, it also includes:

[0033] Vibrating hopper with a vibrating hopper outlet at the bottom;

[0034] The material from the vibrating silo is conveyed to the rinsing tank via a silo conveyor. This initial vibration of the silo ensures uniform feeding, facilitating subsequent, efficient, and high-quality material processing by the equipment.

[0035] Preferably, the system also includes an electromagnetic induction separator and a sixth conveyor. The material output from the non-ferrous metal outlet is conveyed to the electromagnetic induction separator via the sixth conveyor. The electromagnetic induction separator includes a metal outlet and a non-metal outlet.

[0036] The sorting machine separates non-ferrous metals (including stainless steel and rinsing sediment, etc.) and outputs them through the non-ferrous metal outlet. Then, the non-ferrous metals are conveyed to the electromagnetic induction sorting machine by the sixth conveyor. The electromagnetic induction sorting machine separates metallic materials (such as stainless steel) from non-metallic materials, thus completing the separation of metallic and non-metallic materials in the non-ferrous metals.

[0037] Preferably, the first conveyor includes a horizontal screw conveyor located at the bottom of the rinsing tank and an inclined screw conveyor located outside the rinsing tank. The outlet of the horizontal screw conveyor is sealed to the inlet of the inclined screw conveyor. The outlet of the inclined screw conveyor is higher than the water level of the rinsing tank, and the material from the outlet of the inclined screw conveyor is conveyed to the dewatering machine. In this way, the submerged material (including metallic and non-metallic materials) at the bottom of the rinsing tank can first enter the horizontal screw conveyor through the inlet, then be conveyed to the inclined screw conveyor, and then the inclined screw conveyor will convey the submerged material upwards and output it through the outlet of the inclined screw conveyor, thereby realizing the conveying of the submerged material from the bottom of the rinsing tank to the dewatering machine via the first conveyor.

[0038] Preferably, the rinsing tank is equipped with a floating material discharge device at the top. The floating material discharge device includes several conveying impellers arranged side by side at the top of the rinsing tank, and the conveying impellers are driven by a motor. In this way, the conveying impellers driven by the motor can rinse out floating debris such as lightweight plastics, dust, and wood blocks from the surface of the rinsing tank.

[0039] Preferably, the polishing machine has a fine chip outlet at the bottom, with a screen inside the outlet, and a fine chip storage bin below the outlet. The powder and small particles generated during the polishing process are screened out and enter the fine chip storage bin.

[0040] The beneficial effects of this utility model are:

[0041] Firstly, the combined separation equipment has a wide coverage and can be applied to the treatment and sorting of waste mixtures in multiple industries (including environmental protection, metallurgy, building materials, ports, slag, etc.), completing the separation of multiple materials in one go.

[0042] Secondly, the combined separation equipment uses different sorting devices to separate materials based on differences in density, properties, and magnetism, thereby improving the separation rate. At the same time, it fully considers the characteristics, proportions, and prices of the required sorting equipment, and rationally arranges the types and order of sorting equipment. Materials with a large proportion are sorted out first, while those with a small proportion are sorted out in subsequent processes. Low-value equipment is configured in the early stages, and high-value equipment is configured in the later stages. By rationally arranging the sorting sequence, it is beneficial to improve the separation rate, reduce equipment power requirements, and save energy and costs. Attached Figure Description

[0065] Specific Implementation Example 1, such as Figure 1 As shown, a combined separation device for waste mixture includes: a rinsing tank 2, a first conveyor 11, a dewatering machine 3, a polishing machine 4, a magnetic separator 6, an eddy current separator 7, a color sorter 8, an X-ray separator 9, and a fluorescence separator 10.

[0066] The first conveyor 11 transports the material at the bottom of the rinsing tank 2 to the dewatering machine 3.

[0067] The material output from the dewatering machine 3 is fed into the polishing machine 4. The polishing machine includes a main outlet. The main outlet of the polishing machine is equipped with a buffer hopper 5. The bottom of the buffer hopper 5 has a hopper outlet. The material polished by the polishing machine is output into the buffer hopper through the main outlet of the polishing machine.

[0068] The material output from the buffer silo is fed into the magnetic separator 6. In this embodiment, the magnetic separator is a drum magnetic separator. The magnetic separator includes a magnetic material outlet and a non-magnetic material outlet. The magnetic separator separates ferromagnetic materials, which are discharged through the magnetic material outlet and then transported to a designated location; the remaining material after iron removal is discharged through the non-magnetic material outlet.

[0069] The material exiting the non-magnetic material outlet enters the eddy current separator 7. The eddy current separator includes a non-ferrous metal outlet and a non-ferrous metal outlet. The eddy current separator is mainly used for separating non-ferrous metal materials and non-ferrous metal materials. The separator separates non-ferrous metals (including stainless steel and washed sediment, etc.) and outputs them through the non-ferrous metal outlet; non-ferrous metal materials (including copper, aluminum, lead, zinc, etc.) are output through the non-ferrous metal outlet.

[0070] The non-ferrous metal material exiting the outlet enters the color sorter 8. The color sorter includes a first outlet and a second outlet. The color sorter separates copper materials with obvious color differences. The copper materials are output through the first outlet of the color sorter, while the remaining non-ferrous metal materials are output through the second outlet of the color sorter.

[0071] The material output from the second outlet of the color sorter enters the X-ray separator 9. The X-ray separator includes a first outlet and a second outlet. The X-ray separator separates aluminum materials and lead-zinc materials with significantly different densities. The aluminum materials are output through the first outlet of the X-ray separator, while the lead-zinc materials are output through the second outlet.

[0072] The material output from the second outlet of the X-ray separator enters the fluorescence separator 10. The fluorescence separator includes a first outlet and a second outlet. The fluorescence separator separates lead-based materials from zinc-based materials based on the difference in their optical spectra. Lead-based materials are output through the first outlet of the fluorescence separator, while zinc-based materials are output through the second outlet.

[0073] This embodiment of a combined separation method for waste mixtures separates the waste metal mixtures according to the following categories: floating debris, non-metallic materials, ferromagnetic materials, non-ferrous metal materials (including stainless steel and washed sediment, etc.), copper materials, aluminum materials, lead materials, zinc materials, etc. Specifically, the operation of the combined separation equipment for waste mixtures in this embodiment is as follows:

[0074] The waste mixture is fed into a rinsing tank, where floating debris (including lightweight plastics, dust, and wood blocks) floats to the top, while the remaining settling materials (including both metallic and non-metallic materials) sink, thus separating the floating debris from the settling materials. The rinsing tank washes out the floating debris such as lightweight plastics, dust, and wood blocks, which are then sent to a floating debris storage bin. The remaining settling material is conveyed from the bottom of the rinsing tank to a dewatering machine via a first conveyor for dewatering.

[0075] After dehydration, the material is fed into a polishing machine for polishing. The polishing machine removes contaminated materials and those that have lost their metallic color due to surface oxidation, restoring the original metallic color through friction and collision. This facilitates higher-quality metal separation by subsequent color sorting equipment. Because the polishing machine operates intermittently, which does not match the frequency of subsequent continuous operation equipment, a buffer hopper is installed at the main outlet of the polishing machine in this design. The polished material is fed into the buffer hopper.

[0076] The material output from the buffer silo is fed into the magnetic separator. The magnetic separator first separates the ferromagnetic material, which is then discharged through the magnetic material outlet and transported to a designated location (in this embodiment, the ferromagnetic material output from the magnetic material outlet is transported to the designated location by the seventh material conveyor). The remaining material after iron removal is discharged through the non-magnetic material outlet, thus completing the separation of the ferromagnetic material from the remaining material.

[0077] The non-magnetic material output from the magnetic separator enters the eddy current separator. The eddy current separator is mainly used for separating non-ferrous metal materials from non-ferrous metal materials. The separator separates non-ferrous metals (including stainless steel and washed sediment, etc.) and outputs them through the non-ferrous metal outlet, which is then transported to a designated location; non-ferrous metal materials (including copper, aluminum, lead, zinc, etc.) are output through the non-ferrous metal outlet, thus completing the separation of non-ferrous metal materials from non-ferrous metal materials.

[0078] The non-ferrous metal material output from the eddy current separator enters the color sorter. The color sorter separates the copper material with obvious color differences and outputs it through the non-ferrous metal outlet. The non-ferrous metal material (including copper, aluminum, lead, zinc and other non-ferrous metals) is output through the non-ferrous metal outlet, thus completing the separation of copper material from other non-ferrous metal materials.

[0079] The color sorter separates copper materials with obvious color differences. The copper materials are output through the first outlet of the color sorter, while the other non-ferrous metal materials are output through the second outlet, thus completing the separation of copper materials from the other non-ferrous metal materials.

[0080] The non-ferrous metal material output from the second outlet of the color sorter enters the X-ray separator. The X-ray separator separates aluminum material and lead-zinc material with large density differences. The aluminum material is output through the first outlet of the X-ray separator, and the lead-zinc material is output through the second outlet of the X-ray separator, thus completing the separation of aluminum material from the remaining lead-zinc material.

[0081] Lead and zinc materials output from the second outlet of the X-ray separator enter the fluorescence separator. The fluorescence separator separates lead and zinc materials based on the difference in their optical spectra. The lead material is output from the first outlet of the fluorescence separator and falls into the lead material bin; the zinc material is output from the second outlet of the fluorescence separator and falls into the zinc material bin, thus completing the separation of lead and zinc materials.

[0082] Compared with traditional sorting methods, the combined separation equipment for waste mixtures in this embodiment has the following advantages:

[0083] Firstly, the combined separation equipment in this solution has a wide coverage and can be applied to the treatment and sorting of waste mixtures in multiple industries (including environmental protection, metallurgy, building materials, ports, slag, etc.). It can separate more than 7 kinds of materials at one time, including non-metallic and metallic complex materials.

[0084] Secondly, the combined separation equipment in this scheme uses different sorting devices to separate materials based on differences in density, properties, and magnetism, thereby improving the separation rate of materials.

[0085] Simultaneously, taking into full account the characteristics, proportions, and prices of the required sorting equipment, the types and order of sorting equipment are rationally arranged. Materials with a large proportion are sorted first, while those with a small proportion are sorted in subsequent processes. Low-value equipment is configured in the early stages, and high-value equipment in the later stages. Early-stage equipment has a large processing capacity, so lower-cost equipment is used; later-stage equipment has a smaller processing capacity, so higher-cost equipment is used. This rational arrangement of the sorting sequence helps improve the separation rate, reduce equipment power requirements, and save energy and costs. In our company's implementation of the combined separation device in this embodiment, the purchase prices of the main equipment—magnetic separator, eddy current separator, X-ray separator, and fluorescence separator—did differ by up to five times for the same processing capacity. The magnetic separator had the lowest purchase price, while the fluorescence separator was the most expensive and was placed last.

[0086] Furthermore, such as Figure 1 As shown, a combined separation device for waste mixtures includes a vibrating silo 1 and a silo conveyor 16. The bottom of the vibrating silo has a vibrating silo outlet. The material output from the vibrating silo outlet is conveyed to a rinsing tank 2 via the silo conveyor. The waste metal mixture is first fed into the vibrating silo, where it is vibrated and then output through the vibrating silo outlet; it is then conveyed to the rinsing tank via the silo conveyor. In this way, the vibration of the vibrating silo can achieve uniform feeding, facilitating uniform, efficient, and high-quality material processing by subsequent equipment.

[0087] Furthermore, such as Figure 1 As shown, a combined separation device for waste mixtures further includes a second conveyor 12, a third conveyor 13, a fourth conveyor 14, and a fifth conveyor 15. The second, third, fourth, and fifth conveyors are all material conveyors. Material output from the dewatering machine 3 is conveyed to the polishing machine 4 via the second conveyor 12. Material from the buffer silo 5 is conveyed to the magnetic separator 6 via the third conveyor 13. Material from the non-ferrous metal outlet is conveyed to the color sorter 8 via the fourth conveyor 14. Material output from the second outlet of the X-ray separator is conveyed to the fluorescence separator 10 via the fifth conveyor 15.

[0088] Furthermore, such as Figure 1 , Figure 2As shown, a combined separation device for waste mixtures further includes an electromagnetic induction separator 17 and a sixth conveyor 18. Material output from the non-ferrous metal outlet is conveyed to the electromagnetic induction separator 17 via the sixth conveyor 18. The electromagnetic induction separator includes a metal outlet and a non-metal outlet. Material output from the metal outlet is conveyed to a metal silo via a conveyor belt, and material output from the non-metal outlet is conveyed to a non-metal silo via a conveyor belt. The separator separates non-ferrous metals (including stainless steel and bleached sediment, etc.) which are output through the non-ferrous metal outlet and then conveyed to the electromagnetic induction separator via the sixth conveyor. This electromagnetic induction separator separates metallic materials (e.g., stainless steel) from non-ferrous materials. The metallic materials (e.g., stainless steel) are output through the metal outlet and conveyed to the metal silo via a conveyor belt; the non-ferrous materials are output through the non-ferrous metal outlet and conveyed to the non-ferrous silo via a conveyor belt, thus completing the separation of metallic and non-ferrous materials within the non-ferrous metals.

[0089] Furthermore, such as Figure 1 , Figure 3 As shown, the first conveyor 11 includes a horizontal screw conveyor 11.1 located at the bottom of the rinsing tank and an inclined screw conveyor 11.2 located outside the rinsing tank. The outlet of the horizontal screw conveyor is sealed to the inlet of the inclined screw conveyor, and the outlet height of the inclined screw conveyor is higher than the horizontal level of the rinsing tank. The material at the outlet of the inclined screw conveyor is conveyed to the dewatering machine. Thus, the submerged material (including metallic and non-metallic materials) at the bottom of the rinsing tank can first enter the horizontal screw conveyor through the inlet, then be conveyed to the inclined screw conveyor, and then the inclined screw conveyor conveys the submerged material upwards and outputs it through the outlet of the inclined screw conveyor, thereby realizing the conveying of the submerged material from the bottom of the rinsing tank to the dewatering machine via the first conveyor.

[0090] The rinsing tank 2 is equipped with a floating material discharge device at its top. The floating material discharge device includes several conveying impellers 2.1 arranged side by side at the top of the rinsing tank, and the conveying impellers are driven by a motor. In this way, the conveying impellers driven by the motor can rinse out floating debris such as lightweight plastics, dust, and wood blocks from the surface of the rinsing tank.

[0091] In one implementation, each conveying impeller corresponds to a motor, and each conveying impeller is driven by a corresponding motor.

[0092] In another embodiment, all conveying impellers share a single motor, and the shafts of any two adjacent conveying impellers are connected by a synchronous belt drive. The motor drives the shaft of one of the conveying impellers to rotate, thereby causing all the conveying impellers to rotate synchronously.

[0093] In the third embodiment, each conveying impeller is divided into two groups, with each group comprising at least two conveying impellers. Each group of conveying impellers shares a single motor. Within the same group, the shafts of any two adjacent conveying impellers are connected via a synchronous belt drive. The motor drives the shaft of one of the conveying impellers to rotate, thereby causing all the conveying impellers to rotate synchronously.

[0094] Furthermore, such as Figure 1 As shown, the polishing machine 4 has a fine chip outlet at the bottom, a screen inside the fine chip outlet, and a fine chip storage bin 4.1 below the fine chip outlet. The powder and small particles generated during the polishing process are screened out by the screen and enter the fine chip storage bin.

[0095] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
