Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution:
the utility model provides a high-speed pulse flame galvanizing furnace of natural gas, includes main part 1, the inside of main part 1 is provided with many places zinc-plated chamber 2, zinc-plated chamber 2 fit in has zinc-plated rack 3, evenly be provided with many places through-hole 5 around zinc-plated rack 3, the front and back both sides face of main part 1 all is provided with many places air inlet grille 6, the bottom of main part 1 front and back side is provided with natural gas line 7, natural gas line 7 is connected with many places pulse flame frame 8, pulse flame frame 8's inboard evenly is provided with many places nozzle 9.
The galvanized placing frame 3 is in clearance fit with the galvanized cavity 2; wherein, the top of the galvanized placing frame 3 is limited by a limiting block 4, and the limiting block 4 is fixed on the top surface of the main body 1.
