Description

Technical Field

[0001] The utility model relates to the technical field of electric furnace dust removal, in particular to a mobile electric furnace dust removal system. Background Art

[0002] At present, the basic principle of smelting processing is to melt the raw materials to make it a flowing liquid, and then pour it into a mold to solidify it into a desired shape. The key to the smelting process is to control the smelting temperature, smelting time and smelting environment. The most obvious problem of the smelting environment is the treatment of the smoke generated by the smelting process. The authorized patent with announcement number CN204240816U discloses a "two-in-one electric furnace dust removal system, including an electric furnace dust removal device, a spheroidizing bag dust removal device and an exhaust duct". After specific implementation, "the spheroidizing bag dust removal device and the electric furnace dust removal device are combined into one, and a duck tongue-shaped cover plate is extended on the electric furnace dust removal device. When discharging molten iron, the hook hoists the spheroidizing bag through the chute in the middle of the spheroidizing bag dust removal device. During the process of discharging molten iron, the spheroidizing bag dust removal device maintains a fixed distance from the spheroidizing bag. The smoke and dust emitted from the spheroidizing bag enters the exhaust duct through the suction of the exhaust duct and will not emerge again. No manual dust removal is required during iron discharging, thereby improving work efficiency."

[0028] The number of dust hoods 3 is the same as the number of smelting furnaces 2 and is not less than two. The first slide rail 4 and the second slide rail 5 can both provide movement guidance for not less than two dust hoods 3, providing structural conditions for multiple workstation processing and expanding the use effect of the overall equipment.

[0029] Working principle: When in use, for the smelting electric furnace 2 in the process of processing, push and remove the dust cover 3, so that the dust cover 3 covers the smelting electric furnace 2 under the guidance and support of the first slide rail 4 and the second slide rail 5, and after the dust cover 3 covers the smelting electric furnace 2, the exhaust pipe 6 and the transition pipe port 8 will be aligned and movably connected;

[0030] After the adjustment is completed, the large-scale smoke purifier connected to the guiding air pipe 7 is started, so that the smoke generated by the smelting electric furnace 2 is first spatially confined by the dust hood 3, and then enters the guiding air pipe 7 through the exhaust pipe 6 and the transition pipe mouth 8, and finally is absorbed and purified by the large-scale smoke purifier through the guiding air pipe 7.

[0039] After the adjustment is completed, the large-scale fume purifier connected to the guiding gas pipeline 7 is started, so that the fume generated by the smelting electric furnace 2 is first spatially confined by the dust removal cover 3, and then enters the guiding gas pipeline 7 through the exhaust pipe 6 and the transition pipe port 8, and finally is absorbed and purified by the large-scale fume purifier through the guiding gas pipeline 7;

[0040] When the rubber sealing ring plate 9 fails in structure, the detection data of the smoke in the connection gap between the semiconductor gas sensor 13 and the transition pipe port 8 will increase, and the user can understand and deal with it in time through the background equipment.
