Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting, in particular to a slag recycling smelting processing device. Background Art

[0002] Smelting is a pyrometallurgical process in which metal materials and other auxiliary materials are put into a heating furnace to melt and temper. The materials in the high-temperature furnace undergo certain physical and chemical changes to produce crude metal or metal enriched products and slag.

[0003] When recycling metal slag, it is necessary to smelt the slag. Existing smelting devices generally use flame heating and resistance heating. Flame heating uses consumables, has high energy consumption and unstable temperature. Resistance heating has the disadvantages of high cost, limited heating position and complex equipment. In addition, the existing induction heating method cannot achieve mass production and has low output. Utility Model Content

[0004] The purpose of the utility model is to provide a smelting processing device for slag recovery, which has the advantages of reducing energy consumption by induction heating, high efficiency and batch production, and high production capacity, so as to solve the problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a smelting processing device for slag recovery, comprising a loading barrel, a heating barrel, a storage barrel and an assembly plate, a discharge pipe is installed through the lower side of the front end of the storage barrel, the heating barrel is fixedly installed at the upper end opening of the storage barrel by bolts, an inner plate is fixedly provided on the upper side of the interior of the heating barrel, and a circular array of material holes is provided on the inner plate, the assembly plate is installed on the lower end surface of the inner plate, grids are distributed in a circular array on the assembly plate, and the grids correspond to the material holes, a graphite sleeve is provided on the upper side of the grid, an inductor coil is fixedly provided on the outer side of the graphite sleeve, the loading barrel is fixed at the upper end opening of the heating barrel, and a material distribution rack is provided on the inner side of the loading barrel.

[0006] When using a slag recovery smelting processing device in the technical solution, the metal slag is introduced into the upper barrel through the material guide device, and the slag is introduced into the heating barrel from the side gap opening through the cone cap and the material distribution rack. The slag is distributed in the outer ring on the upper side of the inner plate inside the heating barrel. When the slag enters the material hole, it is introduced into the corresponding graphite sleeve, and the slag is blocked by the grid. When the material holes in the outer ring are filled, excess slag is introduced through the material holes on the inner side of the arc surface to fill the material holes. The induction coil is started, and the graphite sleeve and the slag inside it are heated by induction heating. After the slag is melted, it becomes liquid metal and passes through the grid and is introduced into the storage barrel.

[0007] Preferably, a foot pad is fixed on the outer side of the lower end surface of the storage barrel, and a total of four foot pads are provided, and the four foot pads are distributed in an array, and an anti-slip sleeve is fixed on the lower end of the foot pad. The placement support of the storage barrel is achieved through the foot pad, and the anti-slip pad increases friction and ensures the stability of the support.

[0008] Preferably, the upper end surface of the inner plate is provided with a concave conical groove, and the conical groove is adapted to the material hole. Through the concave conical groove design, the slag introduced into the outer circle of the upper end surface of the inner plate moves to the inner center, ensuring the filling quality of the material hole.

[0009] Preferably, the assembly plate is fixedly mounted on the inner plate by fixing bolts, and a feeding opening is provided in a circular array on the assembly plate, and a grid is fixed in the feeding opening. The assembly plate installed by fixing bolts is convenient for later disassembly, and the grid realizes a sieve-type closure of the feeding opening.

[0010] Preferably, the lower end of the graphite sleeve is fixed on the assembly plate, and a groove is provided on the outer side of the graphite sleeve, and the inductor coil is located in the groove. The inductor coil is accommodated in the groove to achieve an integrated installation connection.

[0011] Preferably, the graphite sleeve is adapted to the size of the material hole, and the height of the graphite sleeve is less than the depth of the material hole. The graphite sleeve is located in the corresponding material hole, and its height is lower than the material hole for easy feeding.

[0012] Preferably, the outer annular array of the material distribution rack is provided with a material feeding gap, and the material feeding gap corresponds to the outer ring of the upper end surface of the inner plate. The introduced slag passes through the material distribution rack and enters the outer ring of the upper end surface of the inner plate through the material feeding gap.

[0013] Preferably, a cone cap is fixed at the middle of the upper end surface of the material distribution frame, so that the slag introduced into the upper barrel can be diverted to the side of the material distribution frame through the cone cap.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the external power supply is used, and the operator starts the device through the external control device, and the metal slag is introduced into the upper barrel through the material guide device, and the slag is introduced into the heating barrel from the side gap opening through the cone cap and the material distribution rack. The slag is distributed in the outer ring on the upper side of the inner plate inside the heating barrel. When the slag enters the material hole and is introduced into the corresponding graphite sleeve, the slag is blocked by the grid. When the material holes in the outer ring are filled, excess slag is introduced through the material holes on the inner side of the arc surface to fill the material holes. The induction coil is started, and the graphite sleeve and the slag inside it are heated by induction heating. After the slag is melted, it becomes liquid metal and passes through the grid and is introduced into the storage barrel. The device has a simple structure and is easy to operate. It reduces energy consumption by induction heating and enhances efficiency. At the same time, multiple material holes and graphite sleeves can be used for batch melting and processing of slag to ensure production capacity. BRIEF DESCRIPTION OF THE DRAWINGS
