Background
At present, according to the requirements of a hot galvanized plate production process, an air knife in the prior art needs an air blower to be in butt joint with an air inlet of an air knife girder through a special air supply pipeline, then is in butt joint with an air inlet of a knife body of the air knife through an air outlet of the air knife girder, supplies air to the air knife girder according to the requirements of set air flow rate and air pressure, butt joints the air through the air knife girder, conveys the air to the knife body of the air knife, circulates through the knife body, and then reaches an air blowing port of the knife body of the. An air knife body is key equipment for ensuring the production core of a galvanized plate and mainly comprises a long knife body structure, a knife body inner cavity structure, an air knife lip and an air blowing structure, wherein the air knife body is arranged on an air knife girder and is in butt joint with an air outlet of the air knife girder through an air inlet, the end of the air knife body is the air knife lip, the length of the upper knife lip and the length of the lower knife lip are generally 0.75-2 m according to the production specification requirement of the galvanized plate, the gap between the knife lips is also called an air blowing opening, the width is about 0.03 mm, air flow enters the inner cavity of the knife body through the air inlet, and flows into the air blowing opening of the knife lip to be sprayed, and zinc liquid of. The air flow, the air flow strength and the smoothness of the air knife body are the key points of the production variety efficiency, the quality and the cost consumption of the zinc plate. The structure of the air knife body directly determines the gas conditions of an air flow transmission mode, strength, flow, stability and the like. At present, the air knife body structure used in the prior art adopts a cavity type, a multi-cavity type and a multipoint air supply type structure, and the air flow transmission, the air pressure and the air volume are unchanged. The disadvantages are as follows:
firstly, a cavity type air knife body: the air inlet of the cutter body is butted with the air delivery port of the air knife girder, and the air flow directly flows into the air outlet cavity of the air knife without circular adjustment after entering the cavity of the cutter body and is sprayed out through the air blowing port of the gap of the knife lip to spray and scrape zinc liquid of a zinc plate;
secondly, a plurality of airflow fixing and circulating cavities are arranged in the cutter body of the multi-cavity air knife, and the airflow and the air pressure of the air cannot be adjusted. The thickness and the specification of the zinc plate are directly determined by the strength and the size of the airflow, namely, the production of the zinc plate with multiple functions, multiple varieties and multiple specifications is not suitable to be implemented, the air flow can not be better adjusted, and the quality of the zinc plate can not be effectively ensured;
the multipoint air supply mode is beneficial to the relative consistency of air pressure and air quantity between the left side and the right side of an air outlet of a lip of the long air knife, but the air flow transmission has the sequence and the transmission error, and the optimal air flow required by the operation of equipment cannot be better adjusted and solved to influence the product quality.
In addition, the air knife is arranged on a platform above the zinc pot, the distance between the air knife and zinc liquid is about 1.0 m, the temperature of the zinc liquid is in a molten state for a long time, the ambient temperature of the air knife is about 500 ℃, when air pressure and air flow change and a lip blowing port fault occur in the production operation of the existing air knife, air quantity adjustment or shutdown can be performed only through one fan, and the air knife needs to be lifted away from a high-temperature area to perform air knife lip gap adjustment. Fan adjustment, fan model are fixed, and the adjustment range is limited, and extravagant man-hour influences output, is not suitable for the production of a quick-witted many specifications zinc sheet.
