Description

Technical Field

[0001] This application relates to the technical field of slag flushing recovery, and in particular to a slag flushing recovery device for a smelting furnace. Background Art

[0002] Slag flushing refers to waste or by-products generated during metal smelting, casting, or other metal processing. Usually, slag flushing contains impurities removed from molten metal, uncompletely melted solid particles, or oxides. The treatment and management of slag flushing are important aspects in the industrial process because it not only affects production efficiency but also relates to environmental protection and resource recycling. Currently, during metal smelting, slag flushing is usually manually filtered and recovered by workers using a ladle. However, manual filtering and recovery by workers result in relatively low slag flushing filtration efficiency, which will affect the efficiency of metal smelting. Therefore, a slag flushing recovery device for a smelting furnace is proposed to solve the problems described in the above background art.

[0003] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0004] In order to solve the problem of relatively low efficiency of existing slag flushing filtration and recovery, this application provides a slag flushing recovery device for a smelting furnace.

[0005] The slag flushing recovery device for a smelting furnace provided by this application adopts the following technical solutions:

[0006] A slag flushing recovery device for a smelting furnace includes a mounting frame. A recovery and filtration box is provided at the top of the mounting frame, and a recovery tank is provided at the bottom inside the mounting frame. A screening assembly is provided on the recovery and filtration box. The screening assembly includes an opening which is opened at the top of the recovery and filtration box. A discharge hopper is fixedly connected to one side of the recovery and filtration box, and a baffle is clamped inside the discharge hopper. A filter screen is fixedly connected inside the recovery and filtration box, and a bottom plate is fixedly connected to the bottom of the recovery and filtration box. A drain pipe is fixedly connected to the bottom of one side of the recovery tank. An installation groove is opened at the top of the mounting frame. A connecting pipe is fixedly connected to the bottom of the recovery and filtration box, and a notch is opened at the top of the recovery tank.

[0007] Preferably, the recovery and filtration box is vertically arranged on the top of the recovery tank, and lifting rings are symmetrically welded on the top of the recovery and filtration box.

[0008] Preferably, the bottom end of the recovery and filtration box is arranged inside the installation groove, and the bottom plate is arranged on the top of the installation groove.

[0009] Preferably, the connecting pipe is arranged at the middle position of the bottom of the recovery and filtration box, and the connecting pipe extends to the top of the recovery tank.

[0010] Preferably, the notch extends into the recovery tank, and the end of the connecting pipe is arranged at the notch.

[0011] In summary, the present application includes the following beneficial technical effects:

[0012] By designing the screening assembly, during metal smelting and processing; the molten metal after smelting in the smelting furnace is injected into the recovery and filtration tank from the opening. At this time, under the action of the filter screen, the slag is filtered to the top of the filter screen, while the molten metal is transported to the inside of the recovery tank through the connecting pipe. Finally, after the pouring of the molten metal is completed, the baffle is removed, so that the slag on the filter screen is discharged from the discharge hopper; compared with the prior art, this design can filter and recover the slag in the molten metal, effectively improving the efficiency of slag filtration and also improving the quality of metal smelting.
