Detailed Description
The invention is further elucidated below in conjunction with the accompanying drawings.

Examples:
As shown in fig. 1 to 12, the present solution provides a nonferrous metal sorting apparatus, which is provided with a crushing device 1, a conveying device 2, an air flow sorting device 3, a high temperature impurity removing device 4 and a vortex screening device 5 in order according to the advancing direction of metal garbage. The metal garbage in the scheme refers to nonferrous metals which have been subjected to preliminary screening, and part of the metals have the problems of surface connection or adhesion of plastics and paper products, and in order to remove the plastics and paper products on the surfaces of the nonferrous metals, the scheme introduces a high-temperature impurity removing device 4.
The metal garbage firstly enters the crushing device 1 for extrusion crushing. The crushing device 1 is provided with a driving mechanism, a hopper and a plurality of crushing rollers, the driving mechanism drives the crushing rollers to rotate, metal garbage reaches the crushing rollers along the hopper, and the crushing rollers extrude wires in the metal garbage and screws connected with plastics, so that the metal and the plastics are divided into a plurality of sections and are in a cake shape. The design aims at reducing the weight of single metal garbage and increasing the surface area of the metal garbage so as to facilitate the separation of the subsequent airflow separation device 3.
The crushed metal garbage is sent to an airflow sorting device 3 by a conveying device 2, and the airflow sorting device 3 separates the metal garbage from the plastic and paper products again. The separated metal refuse falls to the conveyor belt 41, and is then sent to the high-temperature impurity removal device 4 by the conveyor belt 41 for treatment.
As shown in fig. 2, in this solution, the high-temperature impurity removing device 4 includes an impurity removing bin 42 and a conveying mesh belt 41, a partial area of the conveying mesh belt 41 is located at the bottom of the airflow sorting device 3, the impurity removing bin 42 includes a high-temperature bin 43, a cleaning bin 44 and a dehumidifying bin 45, where the high-temperature bin 43 is used for heating metal garbage, so that plastics and paper products connected to the surface of the metal garbage are burned and melted, and the metal is separated from impurities, so as to obtain pure metal. The cleaning bin 44 is used for flushing the metal surface by using high-pressure water flow, so that the high-temperature metal is quickly cooled; secondly, the plastic still adhered to the metal surface is separated, and the plastic and the rubber on the metal surface can be insufficiently combusted and melted, so that the plastic and the rubber which are insufficiently combusted on the metal surface are quickly cooled and are condensed to form black solids after the metal reaches the cleaning bin 44, and the black solids can be separated from the metal surface through high-speed water flow. The purpose of the dehumidification bin 45 is to dry the metal to facilitate sorting of the mixed nonferrous metals by the vortex screening apparatus 5. In order to facilitate the vortex screening device 5 to receive the metal after the impurity removal is completed, the vortex screening device 5 is located at one side of the high-temperature impurity removal device 4 away from the airflow separation device 3, and a partial area of the vortex screening device 5 is located below the conveying mesh belt 41.
The vortex screening device 5 is used for separating mixed metals, and sorting and picking out different kinds of metals according to different kinds of metal magnetic force, so as to finish nonferrous metal sorting work.
In this scheme, install first heating roller 431 and second heating roller 432 in the high temperature storehouse 43, conveyer belt 41 is located between first heating roller 431 and the second heating roller 432, first fan 433 and first air knife 434 are installed at the top in high temperature storehouse 43, first fan 433 and first air knife 434 pipe connection, the air-out area of first air knife 434 is towards conveyer belt 41. The first heating roller 431 and the second heating roller 432 squeeze the conveying mesh belt 41 and the metal garbage on the conveying mesh belt 41 to a certain extent, and heat the metal garbage and the sundries on the surface of the metal garbage by using the high temperature of the metal garbage and the sundries so as to melt and burn the sundries. The first fan 433 blows high-speed air flow into the high-temperature bin 43 through the first air knife 434, the high-speed air flow becomes high-temperature air after being heated by the first heating roller 431, the high-temperature air impacts the metal garbage, impurities on the metal garbage are heated for the second time, and pressure is applied to the melted impurities, so that the melted impurities pass through meshes of the conveying mesh belt 41 and fall into the bottom of the high-temperature bin 43, and the separation of the impurities and the metal is completed.
Preferably, an electric heating device is installed between the first heating roller 431 and the first air knife 434, and the purpose of this design is to avoid insufficient temperature of the high-speed air flow.
As shown in fig. 3-4, in order to clean the impurities remained on the metal conveniently, a water diversion pipe 441 is hung on the top of the cleaning bin 44, and a plurality of high-pressure water ports 442 are installed at one end of the water diversion pipe 441 facing the conveying mesh belt 41. In order to accelerate drying, a second fan 451 and a second air knife 452 are arranged at the top of the dehumidification bin 45, the second fan 451 is connected with the second air knife 452, and an electric heating tube 453 is installed between the second air knife 452 and the conveying mesh belt 41.
The bottom of the high temperature bin 43 is provided with an air outlet for connection to an exhaust fan for the purpose of extracting harmful gases from combustion.
The plastic and the rubber are melted after being heated and become a state similar to fluid, at this time, the plastic and the rubber are adhered to the surface of the first heating roller 431, and as the first heating roller 431 rotates, more sundries are accumulated on the surface of the first heating roller 431, and thus the working efficiency of the first heating roller 431 is seriously affected. For this purpose, a protective shell 4311 is mounted on a side of the first heating roller 431 far away from the second heating roller 432, the protective shell 4311 includes a scratch protrusion 4312, the scratch protrusion 4312 is located between the first heating roller 431 and the protective shell 4311, and a gap exists between the scratch protrusion 4312 and the first heating roller 431. When the first heating roller 431 rotates, the scraping protrusions 4312 scrape off the fluid substances accumulated on the surface of the first heating roller 431, so as to avoid too much fluid substances accumulated on the first heating roller 431.
In this embodiment, the first heating roller 431 has the same structure as the second heating roller 432, and therefore, the second heating roller 432 is also mounted with the protective case 4311.
In order to remove impurities on the surface of the first heating roller 431 conveniently, the included angle between the plane of the scraping and rubbing protrusion 4312 and the horizontal plane is a, and a is more than or equal to 45 degrees and less than or equal to 75 degrees.
In order to avoid the rubbing protrusion 4312 from obstructing the rotation of the first heating roller 431, and simultaneously, in order to avoid the rubbing protrusion 4312 from being difficult to remove sundries on the surface of the first heating roller 431, the rubbing protrusion 4312 is positioned in the rotation direction of the first heating roller 431, and a gap between the rubbing protrusion 4312 and the first heating roller 431 is x, and x is more than or equal to 1mm and less than or equal to 3mm.
Molten rubber and plastic are liable to accumulate at the mesh of the conveyor belt 41 after cooling, which affects the subsequent impurity removal efficiency. For this reason, as shown in fig. 5-7, the bottom of the impurity removing bin 42 is provided with an impurity removing bin 46, heating roller brushes 461 are installed in the impurity removing bin 46, the conveying mesh belt 41 is located between the two heating roller brushes 461, the heating roller brushes 461 comprise heating roller bodies 4611 and strip brushes 4612, the outer walls of the heating roller bodies 4611 are recessed towards the axle center of the heating roller bodies 4611 to form fixing grooves 4613, the strip brushes 4612 comprise fixing bases 4614, a plurality of heat conducting wires 4615 are installed at the top of the fixing bases 4614, and the top of the fixing bases 4614 are in heat conducting connection with the fixing grooves 4613. The heat conducting wire 4615 in this embodiment is preferably a metal heat conducting wire, which is intended to facilitate heat transfer to the heating roller 4611. The heating roller 4611 heats while rotating, and heat is transferred to the fixed base 4614 through the outer wall of the heating roller 4611 and then to the long brush 4612. After the heated long strip brush 4612 contacts with the conveying net belt 41, the heat conducting wires 4615 pass through the meshes, at this time, the heat conducting wires 4615 heat the plastic and rubber in the meshes to melt the plastic and rubber, and then adhere to the heat conducting wires 4615, at this time, the cleaning work is completed.
After too many sundries are attached to the heat conducting wire 4615, the working capacity of the heat conducting wire is reduced, so that the long brush 4612 needs to be replaced easily, and for this purpose, a blocking table 4616 is arranged at one end of the fixing groove 4613, one end of the fixing base 4614 is abutted against the blocking table 4616, a plurality of threaded holes 4617 are formed in the top of the fixing base 4614, a plurality of threaded holes 4617 are formed around the heat conducting wire 4615, and the fixing base 4614 is connected with the fixing groove 4613 through bolts.
