Description

Continuous multistage countercurrent rinsing structure and water washing system Technical Field The invention relates to the technical field of workpiece cleaning, in particular to a continuous multistage countercurrent rinsing structure and a rinsing system. Background At present, in the fields of cleaning, electroplating, coating and the like, different containers are used for containing different liquids to form a required process flow, so that working procedures of cleaning, electroplating, coating and the like are finished on a workpiece, and the working procedures of degreasing, washing, pickling, washing, electroplating and washing are sequentially carried out on the workpiece. In the prior art, the device for cleaning the workpiece comprises an upper tank body and a lower tank body, wherein the upper tank body is communicated with the lower tank body, a certain amount of water is arranged in a cleaning tank in the upper tank body and used for cleaning the workpiece, the water in the cleaning tank can flow into the lower tank body in the cleaning process, in order to ensure the water supply in the cleaning tank, a driving pump pumps the water in the lower tank body and conveys the water in the cleaning tank, and in order to ensure the water cleanliness in the lower tank body, clean water is injected from one end of the lower tank body, water is discharged from the other end of the lower tank body, dirty water in the lower tank body is discharged after being diluted, and the cleanliness of the water in the lower tank body is ensured, but the cleaning mode of the workpiece is more wasteful of water sources. Disclosure of Invention In view of the above, the present invention provides a continuous multistage countercurrent rinsing structure and a water washing system to solve the problem of water waste in cleaning workpieces. In a first aspect, the present invention provides a continuous multistage counter-current rinse structure comprising: The upper groove body is internally provided with a cleaning groove, two ends of the cleaning groove are respectively provided with a first end and a second end, a plurality of cleaning areas are sequentially arranged in the cleaning groove along the length direction of the upper groove body, and a workpiece is suitable for entering the cleaning areas from the first end and moving towards the second end direction; The lower tank body is internally provided with a plurality of dividing tanks corresponding to the plurality of cleaning areas, water in the cleaning areas is suitable for flowing into the corresponding dividing tanks, the liquid level in the dividing tanks is sequentially reduced from the second end to the first end, the dividing tanks close to the second end are provided with water inlets, the dividing tanks close to the first end are provided with water outlets, and the water in the lower tank body is suitable for flowing from the second end towards the first end; And the driving pump is used for pumping the water in the dividing groove and conveying the water into the corresponding cleaning area. The continuous multistage countercurrent rinsing structure has the beneficial effects that the workpiece enters from the first end of the cleaning tank and moves towards the second end, so that the workpiece sequentially passes through a plurality of cleaning areas to be cleaned, and the workpiece is ensured to be cleaned.
