Description

Technical Field

[0001] The present invention relates to the field of slag recycling, and specifically to a sorting device for recycling domestic waste incineration slag. Background Art

[0002] Waste power generation refers to a form of power generation that burns municipal waste through a special incineration boiler and then generates electricity through a steam turbine generator set. With the improvement of people's living standards, daily necessities have gradually increased, resulting in a gradual increase in domestic waste. The existing waste treatment methods generally adopt landfill methods, but landfill methods will waste a large amount of land resources. Therefore, new technologies for waste incineration power generation have been continuously developed and applied. It can not only reduce waste stacking, eliminate the spread of bacteria and infectious diseases, and reduce air pollution, but also obtain a certain amount of electric energy from it.

[0003] However, when using the technology of waste incineration power generation to treat waste, a certain amount of slag will still be generated. Through comprehensive utilization of these slags, the useful substances mixed in them are extracted for secondary utilization, which can effectively protect the environment and reduce resource waste. For the extraction of magnetic metals from the existing slag, the principle of magnetic attraction is mainly used to adsorb magnetic metals on the magnet, so as to separate the magnetic substances from the slag and collect them for secondary utilization. Although this method is very simple to use, there are still the following problems:

[0004] 1. When sorting the slag, some metal particles in the existing slag are relatively small after crushing and are extremely easy to be wrapped by dust during adsorption, making it difficult to separate them from the dust. Therefore, the sorting efficiency of the device for magnetic metals is poor.

[0005] 2. When sorting the slag, the existing separators are generally of a magnetic mesh sieve structure. After adsorbing metal particles, a large amount of ash slag will adhere to the upper part. Therefore, the metal particles obtained have a large ash content and need secondary separation. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a sorting device for recycling domestic waste incineration slag, which solves the problems raised in the above background art.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A sorting device for recycling domestic waste incineration slag includes an outer cover and a sorting component installed in the outer cover.

[0008] The sorting component includes a stable pan-tilt and a magnetic screening component. The stable pan-tilt is fixedly installed on the inner bottom wall of the outer cover. There are multiple magnetic screening components, all of which are installed on the upper side of the stable pan-tilt. The stable pan-tilt is used to make the multiple magnetic screening components rotate around the inside of the outer cover and is used to make a single magnetic screening component swing.

[0009] An inlet pipe for feeding one of the magnetic screening components is installed on the outer cover. The inner bottom wall of the outer cover is provided with a slag discharge hole and a material discharge hole. After receiving the material, the magnetic screening component can discharge ash slag into the slag discharge hole and can discharge the material after rotating to the position of the material discharge hole.

[0010] Preferably, the magnetic screening component includes an outer magnetic structure and an inner magnetic structure. The inner magnetic structure is installed in the outer magnetic structure, and the two can rotate relative to each other, and there is an annular gap. When the ash slag moves between the two, the internal metal particles can be adsorbed by the inner magnetic structure and the outer magnetic structure.

[0011] It also includes a fixing plate. The outer magnetic structure is installed on the fixing plate and is rotatably connected to it. The fixing plate is installed on the stable pan-tilt. The stable pan-tilt can swing the fixing plate, and when the stable pan-tilt rotates, it can drive the fixing plate to rotate.

[0012] Preferably, the outer magnetic structure includes an outer sleeve. A plurality of coil grooves A are provided on the outer circle of the outer sleeve, and magnetic plates A are fixedly installed on the inner wall of the outer sleeve corresponding to the coil grooves A.

[0013] The inner magnetic structure includes a rotating shaft. A plurality of coil grooves B are fixedly installed on the outer circle of the rotating shaft, magnetic plates B are fixedly installed on the outer circle of the coil grooves B, and a slag chute A is provided between two adjacent coil grooves B.

[0014] Support rings are fixedly installed at both the upper and lower ends of the outer sleeve for supporting the rotation of the rotating shaft.

[0015] The upper support ring is provided with a material guiding hole A, and the material guiding hole A corresponds to the annular gap between the magnetic plate A and the magnetic plate B.

[0016] The lower support ring is of a conical structure, and its inner bottom wall is provided with a material guiding hole B for discharging materials.

[0017] Preferably, both the magnetic plate A and the magnetic plate B are in a long strip shape, and a plurality of longitudinal slag chutes B are provided on both the magnetic plate A and the magnetic plate B.

[0018] Preferably, a conductive ring is installed on the outer circle of the outer sleeve, a conductive coil is installed on the fixing plate, the conductive ring is installed in the conductive coil and is rotatably connected to it. The conductive coil is used to supply power to the outer sleeve, and a shaft sleeve for supporting the rotation of the outer sleeve is also installed on the fixing plate.

[0019] Preferably, two sets of power components are installed on the fixed plate, one of which is used to drive the rotation of the rotating shaft, and the other is used to drive the rotation of the outer sleeve.

[0020] Preferably, the stable pan-tilt includes a base and a stable platform. The stable platform is installed at the upper end of the base. The base is used to drive the rotation of the stable platform. A torsion component equal in number to the magnetic screening component is installed on the side of the stable platform. One end of the torsion component away from the stable platform is connected to the fixed plate, and the torsion component is used to drive the fixed plate to swing.

[0021] Preferably, a valve-equipped nozzle is fixedly installed on the inner top wall of the outer cover. The valve-equipped nozzle corresponds to the feed pipe. The lower end of the valve-equipped nozzle is a pointed end and corresponds to the material guide hole A.

[0022] Preferably, a precious metal discharge pipe communicating with it is installed on the bottom wall of the outer cover corresponding to the discharge hole.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. For this domestic waste incineration slag recycling and separation equipment, by setting up the separation component, after the ash slag is crushed, it can be poured into the magnetic screening component. After magnetic separation, the ash slag will fall into the slag discharge hole, and the metal can fall into the discharge hole, realizing precise separation, separating fine metals, and achieving the final step of recycling of the ash slag.

[0025] 2. For this domestic waste incineration slag recycling and separation equipment, an external magnetic structure and an internal magnetic structure are set. When the ash slag is between the two, with the rotation of the internal magnetic structure, it can fully contact the ash slag. Therefore, the metal particles inside the ash slag can basically be completely collected. Due to the control of electricity, a magnetic field can be formed between the external magnetic structure and the internal magnetic structure, so the effect of separating fine particles is better.

[0026] 3. For this domestic waste incineration slag recycling and separation equipment, a stable pan-tilt is set. The stable pan-tilt can make the magnetic screening component rotate horizontally. Therefore, when the ash slag is inside the outer sleeve, due to the rotation of the outer sleeve, the ash slag can be lifted into the air again and contact the magnetic part of the internal magnetic structure or the external magnetic structure again. Therefore, the ash slag after being swung is more likely to be separated from the metal slag, and the obtained metal particles have less ash content.

[0027] 4. For this domestic waste incineration slag recycling and separation equipment, by setting the coil groove A and the coil groove B, coils can be installed inside both of them. When energized, a magnetic field can be generated, and the magnetic field disappears after power-off. Generally, after demagnetization, there will still be metal slag adhering to the equipment. After demagnetization in this application, the rotating shaft and the outer sleeve can rotate respectively. When they rotate at high speed, the metal slag inside can be thrown out, and the problem of residue is not likely to occur. Description of the Drawings

[0058] It also includes a fixing plate 2023. The outer magnetic structure 2021 is installed on the fixing plate 2023 and is rotatably connected to it. The fixing plate 2023 is installed on the stable cloud platform 201. The stable cloud platform 201 can swing the fixing plate 2023, and when the stable cloud platform 201 rotates, it can drive the fixing plate 2023 to rotate.

[0059] The transverse cross-sections of the inner magnetic structure 2022 and the outer magnetic structure 2021 are both circular. The two are concentrically arranged, and there is usually a distance of about 20 mm between the two. This distance can be changed according to the specifications to be processed.

[0060] The fixing plate 2023 is a U-shaped metal beam. The outer magnetic structure 2021 and the inner magnetic structure 2022 can be stably supported on the fixing plate 2023. When the fixing plate 2023 changes direction, there is enough space inside the outer cover 1.

[0061] The outer magnetic structure 2021 includes an outer sleeve 20211. A plurality of coil grooves A20212 are provided on the outer circle of the outer sleeve 20211. Magnetic plates A20213 are fixedly installed on the inner wall of the outer sleeve 20211 corresponding to the coil grooves A20212.

[0062] The inner magnetic structure 2022 includes a rotating shaft 20214. A plurality of coil grooves B20215 are fixedly installed on the outer ring of the rotating shaft 20214. A magnetic plate B20216 is fixedly installed on the outer ring of the coil groove B20215. A lower ash channel A20217 is provided between two adjacent coil grooves B20215.

[0063] Support rings 20218 are fixedly installed at both the upper and lower ends of the outer sleeve 20211 for supporting the rotation of the rotating shaft 20214.

[0064] The upper support ring 20218 is provided with a material guiding hole A20219, and the material guiding hole A20219 corresponds to the annular gap between the magnetic plate A20213 and the magnetic plate B20216.

[0065] The lower support ring 20218 is of a conical structure, and a material guiding hole B202110 for discharging materials is opened on its inner bottom wall.

[0066] Both the coil groove A20212 and the coil groove B20215 are internally provided with copper / aluminum coils. When current passes through the copper / aluminum coils, an induced magnetic field is generated. The magnetic field intensity (H) is proportional to the current (I) and the number of coil turns (n). By adjusting the current (0 - 100 A), the magnetic field intensity (0.1 - 0.25 T) can be changed. Moreover, iron cores made of industrial pure iron are provided in both the coil groove A20212 and the coil groove B20215, and the magnetic plate A20213 is connected to the iron core and the magnetic plate B20216 is connected to the iron core.

[0067] Bearings are installed in the inner holes of the support rings 20218, and the rotating shaft 20214 is connected to the support rings 20218 through the bearings.

[0068] Both the magnetic plate A20213 and the magnetic plate B20216 are of long strip structures, and a plurality of longitudinal lower ash channels B202111 are provided on both the magnetic plate A20213 and the magnetic plate B20216.

[0069] For the long strip structures of the magnetic plate A20213 and the magnetic plate B20216, on the premise of requiring a sufficient magnetic force environment, multiple groups of coils distributed side by side can be set for energizing and exciting.

[0070] A conductive ring 202112 is installed on the outer ring of the outer sleeve 20211. A conductive ring 202113 is installed on the fixing plate 2023. The conductive ring 202112 is installed in the conductive ring 202113 and is rotatably connected thereto. The conductive ring 202113 is used to supply power to the outer sleeve 20211. A shaft sleeve 202114 for supporting the rotation of the outer sleeve 20211 is also installed on the fixing plate 2023.

[0071] The wire loop cooperates with the conductive coil 202113, and a graphite layer is provided between the two, which can reduce friction, and conduction can be achieved between the conductive ring 202112 and the conductive coil 202113. By setting the insulating layer, single-phase circuits can be distinguished, and the conductive ring 202112 can supply power to the coils inside multiple coil slots A20212.

[0072] At the other end of the outer sleeve 20211, a bearing is fixedly sleeved outside, and the shaft sleeve 202114 is connected to the bearing to achieve low-resistance rotation.

[0073] At one end of the rotating shaft 20214, rotating conductive devices such as brushes and carbon brushes are also installed outside to support the circuit inside the coil slot B20215.

[0074] Two sets of power components 2024 are installed on the fixed plate 2023. One set of power components 2024 is used to drive the rotation of the rotating shaft 20214, and the other set of power components 2024 is used to drive the rotation of the outer sleeve 20211.

[0075] The power component 2024 preferably uses a servo motor. For the power component 2024 that drives the rotating shaft 20214, the servo motor is connected to the rotating shaft 20214 in a form of direct connection by a coupling. For the power component 2024 that drives the outer sleeve 20211, the servo motor is connected in a form of gear meshing. An external gear ring is fixedly installed on the outer circle of the outer sleeve 20211, and the external gear ring is engaged with the gear for transmission.

[0076] The stable pan-tilt 201 includes a base 2011 and a stable platform 2012. The stable platform 2012 is installed at the upper end of the base 2011. The base 2011 is used to drive the rotation of the stable platform 2012. On the side of the stable platform 2012, a number of torsion components 2013 equal to the magnetic separation component 202 are installed. One end of the torsion component 2013 away from the stable platform 2012 is connected to the fixed plate 2023, and the torsion component 2013 is used to drive the swinging of the fixed plate 2023.

[0077] A servo motor is installed between the base 2011 and the stable platform 2012. The servo motor can control the rotation of the stable platform 2012 and can accurately control the angle of the stable platform 2012. A servo motor is also provided inside the torsion component 2013.

[0078] The inner top wall of the outer cover 1 is fixedly installed with a valve nozzle 6. The valve nozzle 6 corresponds to the feed pipe 3, and the lower end of the valve nozzle 6 is a pointed end and corresponds to the material guiding hole A20219.

[0079] A valve is provided inside the valve nozzle 6, which can accurately control the ash discharge amount.

[0080] At the position of the bottom wall of the outer cover 1 corresponding to the discharge hole 5, a precious metal discharge pipe 7 communicating with it is installed.

[0081] The precious metal discharge pipe 7 is used to receive metal slag.

[0082] During use, first, the slag needs to be crushed in the previous process. After crushing, the slag can be fed through the feed pipe 3 and the valve nozzle 6. The valve nozzle 6 is quantitatively fed through control. First, a certain amount of slag is fed into the guide hole A20219. Then, the slag will be between the outer magnetic structure 2021 and the inner magnetic structure 2022. During this process, the coils inside the magnetic plate A20213 and the magnetic plate B20216 are both energized, and a magnetic field is formed between them. The power assembly 2024 drives the rotation of the rotating shaft 20214, causing the inner magnetic structure 2022 to rotate. Some metal slag will be adsorbed by the magnetic plate B20216 or the magnetic plate A20213, and some slag without metal will fall from the guide hole B202110 at the bottom;

[0083] After injecting the slag, the stabilizing table 2012 moves the outer sleeve 20211 filled with slag to the next station and gradually makes the outer sleeve 20211 horizontal. Then, the power assembly 2024 rotates the outer sleeve 20211. The slag inside the outer sleeve 20211 will be lifted and vacated by the magnetic plate A20213 of the outer sleeve 20211 and then evenly sprinkled on the magnetic plate A20213. During this process, the rotating shaft 20214 can still rotate at a low speed. The rotating direction of the rotating shaft 20214 can be opposite to that of the outer sleeve 20211, and there is a certain rotational speed difference. Then, the metal particles wrapped in the ash slag will break away from the ash slag, and after breaking away from the ash slag, they can be adsorbed by the magnetic plate A20213 or the magnetic plate B20216; The ash slag without metal will be in the gap between the magnetic plate A20213 or the magnetic plate B20216, or in the lower ash channel A20217;

[0084] The stabilizing table 2012 continues to rotate the outer sleeve 20211 to the next station. At this time, the outer sleeve 20211 returns to the vertical state again. The slag in the lower ash channel A20217 will fall from the guide hole B202110. After being processed through three stations, the metal slag contained in the once-fed slag is basically completely collected, and then the slag without metal will be discharged from the slag discharge hole 4;

[0085] Immediately, the stabilizing table 2012 rotates the outer sleeve 20211 to the last station. At this time, all the coils of the outer sleeve 20211 are powered off, and the magnetic plate A20213 and the magnetic plate B20216 lose their magnetism. The metal slag will fall from the guide hole B202110 and be discharged through the precious metal discharge pipe 7. Finally, the rotating shaft 20214 or the outer sleeve 20211 can rotate at a high speed to use centrifugal force to throw off the adsorbed metal slag.
