Embodiment Construction

[0019] see figure 1 , figure 2 , a zinc pot bottom slag cleaning device, including slag introducing pipe parts, a vacuum chamber 7 and a vacuum pump 6. The slag introduction pipe components include slag introduction pipe 5, quick joint 16, slag discharge pipe 17 and stop valve 18. The slag discharge pipe 17 is connected to the stop valve 18 and extends into the vacuum chamber 7. The slag pipe 5 and the slag introducing pipe 5 extend into the bottom of the zinc pot 13, and the head of the slag introducing pipe 5 is comb-shaped, which is used as the bottom slag suction port 22, see image 3 . The slag introducing pipe 5 and the slag discharging pipe 17 can be quickly connected and disassembled through the quick connector 16, and the slag introducing pipe 5 is fixed with a pipe clamp 15.

[0020] see Figure 4 , figure 2 , the vacuum chamber 7 is made up of a vacuum chamber body 27, a sealing cover 23, a sealing ring 25, and mounting bolts 24. There are three holes on the...

Abstract

The invention relates the hot galvanizing, especially the zinc pan slag removal device. The device comprises drafting slag part, vacuum case and vacuum pump. The drafting slag part comprises drafting slag pipe, express connector, slag-off pipe and cut-off valve. One end of slag-off pipe is connected with vacuum case, the other end of it is connected with drafting slag pipe through express connector, and drafting slag pipe extends in the bottom of zinc pan. The vacuum case comprises body and airtight cover, on the airtight cover there are three pore paths, one of which is connected with slag-off pipe, the second of which is connected with aspirator, the third of which is connected with vacuum pump, and the vacuum case body is connected with airtight cover by screw. The invention has the advantages of simple structure and installation, easy operation, high cleaning efficiency and low cost.

Description

(1) Technical field [0001] The invention relates to hot-dip galvanizing technology, in particular to a cleaning device for zinc pot bottom slag. (2) Background technology [0002] At present, in the continuous hot-dip galvanizing production process of strip steel, the zinc slag in the zinc pot has a great influence on the quality of hot-dip galvanizing products. There are three types of zinc slag in the zinc pot: scum, bottom slag and slag in molten metal. During the galvanizing process, the bottom slag keeps increasing, and when it accumulates to a certain amount, it needs to be cleaned up in time to ensure smooth galvanizing production. [0003] Existing bottom slag cleaning can be divided into automatic and manual methods. Automatic methods such as: Chinese Patent Publication No. 1470838 discloses a device and method for removing bottom slag in the molten metal pool of the smelting crucible. This patent adopts the airflow suction method , when the gas in the gas supply ...
