Hull cell structure for plating solution detection

Abstract

The invention discloses a Hull cell structure used for plating solution detection, comprising an outer tank, an inner tank, a first anode, a first cathode, a second anode, a second cathode, a heating rod, a motor, a stirring shaft, and a through hole and the top edge; the outer tank is located outside the inner tank, two parallel side walls of the inner tank are provided with through holes, and the other two pairs of sides of the inner tank are respectively equipped with a first anode and a first cathode, so The outer tank and the inner tank are connected through through holes, the two opposite sides of the outer tank are respectively provided with a second anode and a second cathode, the outer tank is provided with a heating rod, and the stirring shaft is installed on Inside the outer tank. The invention has a large capacity of ferrying liquid, and under the action of stirring blades, the ferrying liquids of the inner tank and the outer tank are connected with each other, thereby avoiding the impact on the experimental results caused by the rapid change of the ferrying liquid. The invention has double-layered inner tanks and outer tanks, increases the capacity of the liquid during the experiment, and can test four test pieces at the same time, thus improving the test efficiency.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a Hull cell structure used for plating solution detection. Background technique [0002] The Hull cell is usually made of insulating materials such as glass or organic hard polyvinyl chloride. The bottom surface is trapezoidal. The cathode and anode are placed on two sides that are not parallel. The near end is called the near end; the other end is far from the anode, called the far end. Since the current flows from the anode to the cathode with different paths from the proximal end to the distal end, the resistance of the bath liquid in different paths is also different, so the current density on the cathode gradually increases from the far end to the proximal end. [0003] The designer of the present invention finds that the existing Hull cell has the following disadvantages: 1.) the existing Hull cell can only do two test pieces in one test, and the test efficiency is ...
