Description

Technical Field

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

[0002] Garbage-to-energy refers to a form of power generation that uses a special incineration boiler to burn urban garbage and then generates electricity through a steam turbine generator set. With the improvement of people's living standards, daily necessities have gradually increased, which has also led to a gradual increase in domestic garbage. The existing garbage disposal method generally adopts landfill, but the landfill method will waste a lot of land resources. Therefore, the new technology of garbage incineration power generation has been continuously developed and applied, which can not only reduce garbage stacking, eliminate the spread of bacteria and infectious diseases, and reduce air pollution, but also obtain a certain amount of electricity from it.

[0003] The use of waste incineration power generation technology to treat garbage will still produce a certain amount of slag. Through comprehensive utilization of these slags, the useful substances mixed in the middle can be extracted for secondary use, which can effectively protect the environment and reduce resource waste. The existing slag is used to extract magnetic metals, mainly by using the principle of magnetic attraction to adsorb magnetic metals on magnets, thereby separating the magnetic substances from the slag, collecting them, and reusing them. Although this method is very simple to use, it still has the following problems: 1. When sorting slag, some metal particles in the existing slag are small after being crushed. They are easily wrapped by dust during adsorption and difficult to separate from the dust, resulting in poor sorting efficiency of the equipment for magnetic metals.

[0004] 2. When sorting slag, the existing separators are generally magnetic mesh structures. After the metal particles are adsorbed, more ash will adhere to the top, so the obtained metal particles have a large ash content and require secondary separation. Summary of the invention

[0011] Preferably, the magnetic plate A and the magnetic plate B are both long strip structures, and a plurality of longitudinal ash paths B are provided on the magnetic plate A and the magnetic plate B.

[0012] Preferably, the outer ring of the outer sleeve is equipped with a conductive ring, the fixed plate is equipped with a conductive ring, the conductive ring is installed in the conductive ring and is rotationally connected thereto, the conductive ring is used to supply power to the outer sleeve, and the fixed plate is also equipped with a shaft sleeve for supporting the rotation of the outer sleeve.

[0013] Preferably, two groups of power components are installed on the fixed plate, one group of power components is used to drive the rotating shaft to rotate, and the other group of power components is used to drive the outer sleeve to rotate.

[0014] Preferably, the stabilizing pan-tilt head includes a base and a stabilizing platform, the stabilizing platform is installed on the upper end of the base, the base is used to drive the stabilizing platform to rotate, a torsion component equal to the magnetic screening component is installed on the side of the stabilizing platform, the end of the torsion component away from the stabilizing platform is connected to the fixed plate, and the torsion component is used to drive the fixed plate to swing.

[0018] 2. The domestic waste incineration slag recycling and sorting equipment is equipped with an external magnetic structure and an internal magnetic structure. When the ash is between the two, as the internal magnetic structure rotates, it can fully contact the ash, so the metal particles inside the ash can be basically completely collected.

[0019] 3. The domestic waste incineration slag recycling and sorting equipment is provided with a stable pan-tilt, which can make the magnetic screening component rotate horizontally. Therefore, when the ash is inside the outer sleeve, the rotation of the outer sleeve can make the ash vacate again and contact the magnetic part of the inner magnetic structure or the outer magnetic structure again.

[0020] 4. The domestic waste incineration slag recycling and sorting equipment is equipped with coil slots A and B, both of which can be equipped with coils. A magnetic field can be generated when power is on, and the magnetic field disappears after power is off. Generally, metal slag will still adhere to the equipment after demagnetization. After demagnetization in this application, the shaft and the outer sleeve can rotate separately. When the two rotate at high speed, the internal metal slag can be thrown out, and the problem of residual is not easy to occur. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Coil slot A20212 and coil slot B20215 are both equipped with copper / aluminum coils. Current passes through the copper / aluminum coils to generate an induced magnetic field. The magnetic field strength (H) is proportional to the current (I) and the number of coil turns (n). The magnetic field strength (0.1~0.25T) is changed by adjusting the current (0~100A).

[0036] A bearing is installed in the inner hole of the support ring 20218, and the rotating shaft 20214 is connected to the support ring 20218 through the bearing.

[0037] Both the magnetic plate A20213 and the magnetic plate B20216 are long strip structures, and both the magnetic plate A20213 and the magnetic plate B20216 are provided with multiple longitudinal ash paths B202111.

[0041] The other end of the outer sleeve 20211 is fixed with a bearing, and the shaft sleeve 202114 is connected to the bearing to achieve low-resistance rotation.

[0042] One end of the rotating shaft 20214 is also equipped with rotating conductive devices such as brushes and carbon brushes to support the circuit inside the coil slot B20215.

[0043] Two groups of power components 2024 are installed on the fixed plate 2023, one group of power components 2024 is used to drive the rotating shaft 20214 to rotate, and the other group of power components 2024 is used to drive the outer sleeve 20211 to rotate.

[0044] The power component 2024 preferably uses a servo motor to drive the power component 2024 of the rotating shaft 20214. The servo motor is directly connected to the rotating shaft 20214 by a coupling, and drives the power component 2024 of the outer sleeve 20211. The servo motor is connected by gear meshing. The outer ring of the outer sleeve 20211 is fixedly installed with an outer gear ring, and the outer gear ring and the gear achieve meshing transmission.

[0045] The stabilizing pan-tilt platform 201 includes a base 2011 and a stabilizing platform 2012. The stabilizing platform 2012 is installed on the upper end of the base 2011. The base 2011 is used to drive the stabilizing platform 2012 to rotate. A torsion component 2013 equal to the magnetic screening component 202 is installed on the side of the stabilizing platform 2012. The end of the torsion component 2013 away from the stabilizing platform 2012 is connected to the fixed plate 2023. The torsion component 2013 is used to drive the fixed plate 2023 to swing.

[0047] A valved nozzle 6 is fixedly mounted on the inner top wall of the outer cover 1. The valved nozzle 6 corresponds to the feed pipe 3. The lower end of the valved nozzle 6 is a tip portion and corresponds to the material guide hole A20219.

[0048] A valve is provided inside the valve nozzle 6 to accurately control the amount of ash discharged.

[0051] When in use, first the slag needs to be crushed in the previous procedure, and the crushed slag can be fed through the feed pipe 3 and the valved nozzle 6. The valved nozzle 6 is controlled to feed quantitatively, and first a quantitative amount of slag is fed into the guide hole A20219, and then the slag will be between the external magnetic structure 2021 and the internal magnetic structure 2022. During this process, the coils inside the magnetic plate A20213 and the magnetic plate B20216 are energized, and a magnetic field is formed between the two. The power component 2024 drives the shaft 20214 to rotate, so that the internal magnetic structure 2022 rotates, and some metal slag will be adsorbed by the magnetic plate B20216 or the magnetic plate A20213, and some slag that does not contain metal will fall from the guide hole B202110 at the bottom; After the slag is injected, the stabilizing table 2012 moves the outer sleeve 20211 filled with slag to the next station and gradually turns the outer sleeve 20211 horizontally. Then, the power assembly 2024 rotates the outer sleeve 20211. The slag inside the outer sleeve 20211 is lifted up and emptied 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, so that the rotating shaft 20214 and the outer sleeve 20211 rotate in opposite directions with a certain speed difference. Then, the metal particles wrapped by the slag will separate from the slag, and after separating from the slag, they can be adsorbed by the magnetic plate A20213 or the magnetic plate B20216. The slag that does not contain metal will exist in the gap between the magnetic plate A20213 or the magnetic plate B20216, or in the lower ash channel A20217. The stabilizing table 212 continues to rotate the outer sleeve 20211 to the next station. At this time, the outer sleeve 20211 resumes its vertical position, and the slag in the ash lowering channel A20217 falls from the guide hole B202110. After being processed by three stations, the metal slag contained in the slag put in once is basically completely collected, and then the slag without metal is discharged from the slag discharge hole 4. Then the stabilizing table 2012 rotates the outer sleeve 20211 to the last working position. At this time, all the coils of the outer sleeve 20211 are powered off, the magnetic plate A20213 and the magnetic plate B20216 lose their magnetism, and the metal slag falls from the guide hole B202110 and is discharged through the precious metal discharge pipe 7. Finally, the rotating shaft 20214 or the outer sleeve 20211 can rotate at high speed, and the adsorbed metal slag is thrown off by centrifugal force.
