Abstract

The invention relates to a device and a method for accurately sampling plating solution in a plating pot in a hot plating production line. The device comprises a frame (6) positioned on the plating pot (18), wherein one end of the frame (6) is provided with a No.1 asynchronous motor (5); the No.1 asynchronous motor (5) drives a No.1 sliding block (11) to drive a No.2 sliding block (12) to do reciprocating motion on a track (7) by driving a screw rod (8) to rotate; a No.2 asynchronous motor (14) drives a sampler (9) and a sealer (10) to descend to or ascend from the plating solution (19) through a driver (13); the sealer (10) opens or closes a spoon gate (9.1) of the sampler (9) under the drive of a cylinder (16); and the No.1 asynchronous motor (5), the No.2 asynchronous motor (14), an air compressor system (2) and an electromagnetic valve (4) are connected with an electronic control system. The device can accurately samples the plating solution at each point in the plating pot, avoids manual sampling errors and ensures sampling integrity, consistency and repeatability.

Description

technical field

[0001] The invention relates to a liquid sampling device, in particular to a precise sampling device and method for a plating solution in a hot-dip production line, and belongs to the technical field of sampling tools for measuring physical and chemical indexes of liquids. Background technique

[0002] The modern continuous hot-dip galvanizing production line is the infrastructure for cold-rolling plants to produce high-quality hot-dip galvanized sheets for construction, home appliances, and automobiles. also getting higher. In order to obtain a high-quality hot-dip plated surface, the first premise is that the molten bath composition must be reasonably prepared, and the basis for the rational preparation of the bath composition is the accurate analysis of the current status of the bath, that is, it must be established on the basis of the molten bath. On the basis of accurate testing of the composition of the plating solution, and then according to the test ...
