Hydrochloric acid tank

Abstract

The invention discloses a hydrochloric acid tank. The hydrochloric acid tank comprises a tank body, a tank bottom, an acid mist pipeline, a self-circulation pipeline, an acid return pipeline, a conductivity assay pipeline, a regenerated acid entering pipeline, a rinsing water pipeline, an acid pump pipeline, a waste acid discharging pipeline, a waste acid pump supply pipeline and communicating pipelines. The acid mist pipeline, the self-circulation pipeline, the acid return pipeline, the conductivity assay pipeline, the regenerated acid entering pipeline and the rinsing water pipeline are arranged on the top of the tank body, the communicating pipelines are oppositely arranged on two sides of the bottom end of the tank body, the tank bottom is arranged at the bottom of the tank body, the section of the tank bottom is arc-shaped, the waste acid discharging pipeline is arranged at the lower end of the tank bottom, and the acid pump pipeline and the waste acid pump supply pipeline are arranged at the tank bottoms on two sides of the waste acid discharging pipeline. By configuring all pipelines on the acid tank to serve as spare parts, pipelines needed to be connected are connected according to a using position when the acid tank is used on line, and pipeline needed not to be connected are blocked with blank flanges, so that the probability that one spare part replace three acid tanks is achieved. The procurement fund is saved and the occupied space of the spare parts is reduced.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a hydrochloric acid tank. Background technique [0002] The pickling production line is a production line that converts hot-rolled raw materials into cold-rolled steel coils through transportation, decoiling, straightening, welding, tension leveling, pickling, edge trimming, rolling, and coiling. Its main technological process is that the hot-rolled coil is transported from the raw material storage to the cold-rolled cross-walking beam. Coil outer diameter measurement device, steel coil width detection device, and steel coil weighing station are arranged on the walking beam. After the steel coil outer diameter data is recorded, the coiling trolley can automatically position the hot-rolled coils to the uncoiler respectively. Corresponding mandrel height. A centering device is also arranged to correct the misalignment of the coil position. The centered steel coil is transp...

AI Technical Summary

Problems solved by technology

The use of acid tanks is targeted. Therefore, according to different purposes and locations, different acid tanks are equipped in different sections of the pickling line, and the types of spare parts are also different. There are three acid tanks in the pickling line of Baotou Steel. The same size and capacity, but the external pipelines are different, and the spare parts are also different, resulting in a large waste
