Description

Technical Field

[0001] The utility model relates to the technical field of iron-making production, in particular to a dust removal device for iron-making. Background Art

[0002] Waste gas emitted from chemical reactions in the production process, such as waste gas generated during smelting, coking, chemical products and steel pickling. The emission of waste gas from steel enterprises is very large and pollutes a wide range. The waste gas emitted by metallurgical kilns has a high temperature. Most of the emissions during steel smelting are iron oxide smoke, which has small particle size and strong adsorption capacity, increasing the difficulty of waste gas treatment. In the blast furnace iron and slag tapping and some processes in the steelmaking process, the generation and emission of smoke is paroxysmal, and most of the emissions are unorganized. The waste gas produced by the steel industry has recovery value, including the recovery and utilization of iron oxide dust.

[0003] Most of the existing iron-making dust removal devices have poor internal dust removal effects, and most of them can only collect and store iron filings and powder inside the iron-making smoke. The smoke generated by iron-making also contains other harmful substances and dust. If other harmful substances are not filtered out, the subsequent emission of the smoke will cause pollution to the surrounding environment. In addition, the structural design of the single filter screen plate will become clogged during long-term use, and the operator needs to manually disassemble and clean it, which increases the inconvenience and tediousness of cleaning.

[0022] The driving and collecting assembly includes a rack 13, a motor 14, an incomplete gear 15, a filter screen plate 16, a collecting bin 9 and a through slot 17. The rack 13 is located at one end of the back side at the middle position of the bottom of the oblique double-layer filter screen plate 7. The motor 14 is located at the top of the dust removal tank 2 close to the air pump 5 and directly below the oblique double-layer filter screen plate 7. The output end of the motor 14 is provided with an incomplete gear 15 extending into the interior of the dust removal tank 2, and the incomplete gear 15 is meshed with the rack 13. The collecting bin 9 is located at the top of the dust removal tank 2 away from the motor 14. The top of the collecting bin 9 close to the dust removal tank 2 is provided with a through slot 17 that cooperates with the oblique double-layer filter screen plate 7. The bottom of the collecting bin 9 close to the dust removal tank 2 is provided with a filter screen plate 16 that cooperates with the interior of the dust removal tank 2.

[0023] The tops of the outer sides of the two groups of L-shaped limiting rods 11 are both provided with impact blocks, and the impact blocks cooperate with the oblique double-layer filter screen plate 7 .

[0024] The bottom of the discharge port 3 is covered with a sealing plate matched therewith, and a handle is provided at the bottom of the sealing plate.

[0025] Support plates are disposed on both sides of the bottom of the base 1, and an anti-skid plate is disposed at the bottom of the support plates.

[0026] A U-shaped connecting pipe is provided at the output end of the air pump 5 , and the U-shaped connecting pipe extends to the interior of the filtering water tank 6 .

[0027] Working principle: when in use, the device can be first carried to the designated location and connected to the power supply, and then the external smoke can enter the dust removal tank 2 through the air inlet pipe 8, and the larger impurities inside the smoke can be filtered through the oblique double-layer filter screen 7, and then the smoke passes through a group of guide tubes 4 to the bottom of the dust removal tank 2, and then the iron powder inside the smoke can be adsorbed through the work of the electrostatic plate 10, which is convenient for realizing the separation and collection of the iron powder. Later, the smoke can be pumped into the filter tank 6 through the work of the air pump 5, and the filter liquid stored in the filter tank 6 is used to filter the smoke for the last time, so as to improve the later smoke emission standards and reduce the pollution to the surrounding environment.

When the incomplete gear 15 continues to rotate and disengages from the meshing of the rack 13, the elastic restoring force of the spring 12 can drive the oblique double-layer filter screen plate 7 to collide with the impact block. The vibration generated by the impact can realize the dredging work inside the oblique double-layer filter screen plate 7, and can also increase the rolling speed of impurities on the surface of the oblique double-layer filter screen plate 7. Then the impurities can enter the collection bin 9 through the through groove 17 for collection and storage. Through the structural design of this component, the automatic cleaning function of the oblique double-layer filter screen plate 7 can be realized, without the need for manual disassembly and cleaning by the operator, thereby improving its convenience and flexibility in later use.
