Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing alloy process, in particular to a pneumatic lifting zinc extraction and filtering device for hot-dip galvanizing. Background Art

[0002] Modern galvanized sheet production generally requires a stamping process, which places high demands on the ductility of the strip. Therefore, the strip of the continuous hot-dip galvanizing unit must undergo an annealing process before entering the zinc pot. In order to ensure that the strip is not oxidized under high temperature conditions, it is generally protected by a nitrogen and hydrogen mixed gas. The nose is the key equipment for the annealing furnace to penetrate into the zinc pot, which plays the role of sealing the annealing furnace. After the strip comes out of the annealing furnace, it is directly extended into the zinc pot to complete the galvanizing process.

[0003] When the existing zinc liquid is heated inside the furnace nose, it will evaporate and condense to form zinc ash. The zinc ash and strip steel will react to produce zinc slag. Since the zinc liquid is in a relatively closed environment inside the furnace nose, the zinc ash or zinc slag will adhere to the surface of the strip steel, forming zinc ash marks, which will affect the later production of the strip steel.

[0023] An input end of the zinc extraction pump 9 is provided with an input pipe 10 extending into the interior of the filter bin 11, and an output end of the zinc extraction pump 9 is provided with an output pipe 8. A high-temperature resistant hose 4 is provided at one end of the output pipe 8 away from the zinc extraction pump 9, and the high-temperature resistant hose 4 is communicated with a side of the top of the base 1 away from the filter bin 11, and a connecting plate 7 is provided on the top of the filter bin 11 to be sleeved on the outside of the output pipe 8.

[0027] A through hole is formed on one side of the U-shaped mounting plate 6 close to the connecting plate 7 , and the through hole cooperates with the electric push rod 5 .

[0028] Working principle: When in use, the device can be moved to the designated position first and then the power supply is turned on. When it is necessary to clean the zinc ash or zinc slag inside the furnace nose main body 2, the zinc liquid inside the base 1 can be extracted through the zinc extraction pump 9, so that the zinc liquid can drive its internal impurities to enter the annular scraper bin 3 through the feed port 14, and then enter the filter bin 11 through the connecting pipe 13. Then, the impurities inside the zinc liquid can be filtered and cleaned through the design of the filter screen plate 12. After the filtration, the zinc liquid can be discharged into the furnace nose main body 2 through the input pipe 10, the zinc extraction pump 9, the output pipe 8 and the high temperature resistant hose 4, so as to realize the circulation, filtration and extraction of the zinc liquid inside the furnace nose main body 2;

[0029] During the extraction process, the working principle of the electric push rod 5 is coordinated with the structural design of the connecting plate 7 and the filter bin 11 to drive the filter bin 11 to move, so that the filter bin 11 pulls the annular scraper bin 3 through the connecting pipe 13 to scrape the inner wall of the furnace nose body 2, thereby reducing the adhesion of zinc ash. The reciprocating movement of this component can improve the uniformity and integrity of the subsequent filtration, further improving the quality of the subsequent strip production.
