Hot-dipping galvanized steel pipe equipment system for replacing steam inner blowing

Abstract

The invention discloses a hot-dipping galvanized steel pipe equipment system for replacing steam inner blowing. A plurality of pipe conveying roller beds (1) are arranged on the ground at intervals ina parallel mode, and an outer wipe head (2) is arranged at the upper portion between the two pipe conveying roller beds (1) on the right side of the pipe conveying roller beds (1). Two roller bed tube-turning shafts (3) are symmetrically arranged at the left side of the pipe conveying roller beds (1). A lower pressure cylinder (5) is arranged over an inner blowing V-shaped groove (4). Two rod-turning shafts (6) are symmetrically arranged on one side of the inner blowing V-shaped groove (4). External feeding bevels (7) are arranged outside the rod-turning shafts (6). The equipment system is characterized in that a V-shaped block (5-1) is arranged at the end of the lower pressure cylinder (5), a fixing head (9-2) is arranged at the end of an inner blowing cylinder (9-1), and an inner blowing airway (9-3) and the fixing head (9-2) form a passage. The hot-dipping galvanized steel pipe equipment system for replacing steam inner blowing has the advantages of being simple in structure, convenient to use, high in automation, capable of saving energy and environmentally friendly.

Description

technical field [0001] The invention relates to the field of steel pipe galvanizing processing, in particular to an external wiping and internal blowing mechanism for removing excess zinc layer after steel pipe galvanizing. Background technique [0002] The hot-dip galvanized steel pipe industry currently uses 3500 TC superheated steam to purge the zinc liquid in the inner hole of the galvanized steel pipe. The 3500 TC superheated steam is produced by the boiler, and the hot-dip galvanized steel pipe industry cannot Production, unable to operate, the boiler is an indispensable special strong inspection equipment. To build a hot-dip galvanized steel pipe line needs to invest in a 2-ton boiler with superheated steam, and to invest in a boiler with superheated steam requires an additional investment of more than 500,000 yuan. It costs about 1.1 million yuan to put the boiler into operation for one year. However, with the adjustment of the national industrial structure, environm...

AI Technical Summary

Problems solved by technology

However, with the adjustment of the national industrial structure, and strict approval requirements for environmental protection and safety, it is difficult to obtain approval from relevant departments for the use of boilers.

The approval and use of boilers has seriously restricted the development of this industry. In view of this situation, we have combined the actual production conditions and specific requirements of hot-dip galvanized steel pipes. The dilemma that the industry cannot produce and operate without the boiler has also substantially solved the problems of safety, environmental protection, and cost that plague the galvanized steel pipe industry.
