Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnaces, in particular to a filtering device for a smelting furnace. Background Art

[0002] A smelting furnace is a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then smelts them into the required alloy through operations such as slagging and refining. The main function of the filtration device for the smelting furnace is to remove impurities and bubbles in the molten metal and improve the quality and performance of the metal. Existing smelting furnaces are all smelting equipment that relies on burning direct energy such as coal. The biggest disadvantage of burning direct energy is that it produces a lot of harmful gases and solid particles. In order to solve this problem, the current technology is to put a cloth bag on the surface of the outlet pipe. As the gaps in the cloth bag are filled with solid particles, the cloth bag cannot be used normally and needs to be replaced frequently, which wastes cloth bag resources and reduces the efficiency of smelting.

[0003] For example, the publication number CN201920527901.4 discloses "A bag dust collector for a smelting furnace", which is connected to a dust removal box through the sliding surface of a sliding rod, and the bottom of the dust removal box is in contact with the other side of the top of the base. Then, through the coordinated arrangement of a connecting pipe, a movable pipe, an annular magnet, a support rod, a pull rod, a fixed pipe and an air outlet, the bag can be straightened, and the hair dryer and blower can blow air on the surface of the bag, so that solid particles blocked in the gap of the bag can be blown out, thereby realizing dust removal of the bag, avoiding the current situation of frequent replacement of the bag, and improving the smelting efficiency of the smelting furnace.

[0004] When the existing bag dust collector for smelting furnace is used for auxiliary filtration of the smelting furnace, the internal filter element is mostly fixed inside the smelting furnace, and the filter cartridge needs to be cleaned. Traditional cleaning methods such as mechanical vibration and back-blowing have problems such as incomplete cleaning and damage to the filter bag, which can easily reduce the service life of the bag dust collector.
