Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating cleaning, in particular to a countercurrent rinsing device. Background Art

[0002] The rinsing tank is a commonly used equipment in the electroplating process. It is mainly used to clean some workpieces after electroplating. The cleaning of the workpiece is divided into many steps, including primary cleaning, secondary cleaning and tertiary cleaning.

[0003] The existing rinsing water tank adopts the method of setting a water pump between each tank, so that the water in the previous tank is introduced into the next tank, so that the water flows between each tank to achieve the purpose of live water, but this setting requires multiple water pumps, resulting in a large consumption of electricity. After searching, for example, the patent application number CN202222315759.1 discloses a countercurrent rinsing water tank that is easy to clean and save water. The patent includes: a rectangular multi-joint water washing tank, the interior of which is divided into multiple tank cavities by distributing multiple overflow baffles at intervals, and each tank cavity is connected by an overflow pipe, and the overflow pipe is diagonally distributed, and an inlet pipe and a water outlet are respectively provided at the opposite ends of the rectangular multi-joint water washing tank. The overflow pipe is used to introduce the overflow water from the upper end of the previous tank cavity to the bottom of the next tank cavity. This part of the upper-out and lower-in method also realizes the S-shaped flow trajectory of water, further increasing the residence time of water in each tank cavity and the adequacy of water flow exchange. It can turn over and flow with maximum efficiency to achieve the best cleaning purpose and also save water. Although the application effectively saves electricity and adopts an S-shaped flow trajectory to extend the residence time of water inside the tank cavity, each tank cavity is interconnected through an overflow pipe, and the flow mode of the overflow pipe results in a small overflow surface, poor water exchange effect, and weak cleaning force inside the sink.
