Description

High-pressure purging device for inner wall of furnace nose Technical Field The utility model relates to the technical field of zinc/aluminum plating production, in particular to a high-pressure purging device for the inner wall of a furnace nose. Background In a continuous hot galvanizing/aluminum production line, high-temperature molten metal (for example, zinc liquid at 450 ℃ and aluminum liquid at 650 ℃) needs to be coated on the surface of a high-temperature iron substrate (400-700 ℃) due to the process specificity, a closed furnace nose is needed between a heating furnace of the substrate and a zinc-aluminum pot for dissolving and coating metal, the end part of the furnace nose is immersed in the zinc pot, air isolation is ensured, and coating quality is ensured. The evaporation of high-temperature metal liquid on the inner wall of the furnace nose causes a large amount of metal (zinc/aluminum) to adhere to the inner wall, and in continuous production, particularly on products with high-grade surface requirements, the metal ash falls off to the upper surface of the substrate to form defects, so that the produced coated products are unqualified. Thus, the cleaning of the interior of the furnace nose is complete and can obviously reduce the degradation caused by the defect. The position is in a high-temperature environment (the galvanization temperature is about 470 ℃ and the production temperature of aluminum-silicon is about 660 ℃) and the cleaning of the position must be careful not to blow the metal ash into the heating furnace to pollute the heating furnace environment and ensure that the interior and related structures cannot be damaged during cleaning. Because the upper end of the furnace nose is of a sealing structure, a small hole is reserved at the position of the upper end of the furnace nose for cleaning, cleaning in the prior art only depends on a pipeline to be manually stretched into the small hole for swinging and changing the position for cleaning, all areas cannot be ensured to be cleaned, and meanwhile, the pipe diameter is large and thorough cleaning cannot be well achieved. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide a high-pressure purging device for the inner wall of a furnace nose, which solves the problems that the inner wall of the furnace nose is not thoroughly cleaned and metal ash is easy to fall off to a substrate to cause product defects in the prior art. In order to achieve the above purpose, the utility model adopts the following technical scheme: The utility model provides a stove nose inner wall high pressure sweeps device, includes the body, and the both ends of body are provided with hose connection portion and installation head respectively, hose connection portion passes through the hose and is connected with high-pressure air pump, be equipped with a plurality of nozzle on the installation head, the nozzle all sets up along the opposite direction slope of hose connection portion, and the inclination of each nozzle is different. By adopting the structural design, through the nozzles with a plurality of different angles arranged on the mounting head, when the inner wall of the furnace nose is cleaned, the inner wall of the furnace nose can be cleaned from different angles at the same time, and the problem that dead angles cannot be cleaned is avoided. Preferably, the two ends of the body are connected with the hose connecting part and the mounting head through threads and then fixed through welding. By adopting the structural design, the installation is convenient during the installation through threaded connection, and the installation is finished and then is fixed through welding, so that the high-pressure purging can not fall off. Preferably, a nozzle is arranged in the middle of the mounting head, and a plurality of annular nozzles are arranged along the periphery of the nozzle. Preferably, the nozzle is fixed on the mounting head by threaded connection and welding. Preferably, the aperture of the nozzles is 1.2mm, the number of the nozzles is 7, 1 nozzle is arranged in the middle, the periphery of the nozzles is uniformly distributed, and each nozzle is inclined downwards by 45 degrees.
