Slag discharge device of quick replacement type zinc liquid pump

Abstract

The invention discloses a slag discharge device of a quick replacement type zinc liquid pump. The slag discharge device is characterized in that the head end of a double-end bolt is connected with a power part, and the tail end of the double-end bolt is sequentially connected with a top plate and a bottom plate; a surrounding pipe is surrounded between the top plate and the bottom plate, and is communicated with a flow guide pipe for liquid draining; the top plate, the bottom plate, the surrounding pipe and the flow guide pipe form a cavity for liquid suction; a spiral blade is positioned in the cavity, and is connected with the power part; the bottom plate is provided with a liquid suction port for liquid suction. The slag discharge device of the quick replacement type zinc liquid pump has the advantages that the structure is simple, the detachment is convenient, and the convenience in use is realized; by adopting the opening type connecting method, the running condition of the devicecan be conveniently observed, so that the weight of the whole device is reduced, and the manufacturing cost is reduced; by adopting the spiral blade, the good zinc slag suction effect is guaranteed;the zinc liquid pump can be replaced at site, so that the site overhauling efficiency is improved, the manufacturing cost and overhauling cost are reduced, and the considerable economic benefit is obtained.

Description

technical field [0001] The invention relates to a mechanism for extracting and discharging molten zinc solution, in particular to a quick-change zinc solution pump slag discharge device. Background technique [0002] Zinc nose is the key equipment in the cold-rolled strip galvanizing production line. The molten zinc solution has a strong corrosive effect on iron metal, and combines with the iron elements of the plated strip to form Fe-Zn intermetallic compounds (zinc slag). . The zinc slag in the zinc liquid in the zinc pot adheres to the surface of the steel plate is an important factor affecting the surface quality of the galvanized sheet, so a zinc liquid pump slag discharge device is designed on both sides of the zinc nose skirt body. [0003] Due to the harsh working environment, the slag removal effect of the existing zinc liquid pump structure is average, and the motor often stops due to zinc sticking, and the pump casing is fully enclosed, so the liquid level inside...

AI Technical Summary

Problems solved by technology

[0003] Due to the harsh working environment, the slag removal effect of the existing zinc liquid pump structure is average, and the motor often stops due to zinc sticking, and the pump casing is fully enclosed, so the liquid level inside the zinc liquid pump and the zinc sticking situation cannot be observed , resulting in the impeller shaft and bearing contact parts sticking to zinc and stuck due to the high liquid level

Disassembly is troublesome. When disassembling the zinc liquid pump, it must be removed together with the zinc nose. The zinc liquid pump itself cannot be replaced online, resulting in a long time for on-site maintenance.
