Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more specifically, to an energy-saving water washing tank for a surface treatment production line. Background Technology

[0002] In surface treatment production lines of manufacturing industries such as hardware, electronics, and plastics, workpiece washing is an indispensable and critical process. Its core function is to remove impurities such as oil, metal shavings, and chemical residues adhering to the workpiece surface during previous processing or pretreatment, providing a clean workpiece surface for subsequent processes such as coating, electroplating, and passivation. This directly affects the quality and performance stability of the final product. Therefore, the efficiency and reliability of the washing process have a decisive impact on the production efficiency and product qualification rate of the entire surface treatment production line.

[0003] However, current mainstream water washing equipment on the market has revealed many technical defects that urgently need to be addressed in practical applications, with water waste being the most prominent, becoming a major bottleneck restricting enterprises' green production and cost control. Specifically, the core problem of existing water washing equipment lies in its extremely low water recycling rate and serious waste. Most traditional water washing tanks adopt an open water supply mode of "use once, discharge immediately," directly drawing fresh water to rinse the workpieces. After washing, the wastewater containing impurities is discharged directly into the sewage system without any treatment. In this mode, each batch of workpieces requires a large amount of fresh water, and the concentration of pollutants in this water is often low, making it suitable for recycling and reuse. Direct discharge not only causes a huge waste of water resources but also significantly increases the enterprise's production water costs and subsequent sewage treatment fees, contradicting the current national advocacy of "energy conservation and emission reduction" in green production. Therefore, it is imperative to design an energy-saving water washing tank that can achieve efficient water recycling and is easy to operate to solve the above problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an energy-saving water washing tank for a surface treatment production line, comprising a water washing tank body, a placement plate within the water washing tank body, and filter holes arranged in a rectangular array on the surface of the placement plate. A liquid pump is fixed to the outer wall of the water washing tank body, and a corrugated pipe is connected to the water guide end of the liquid pump. A nozzle is connected to the end of the corrugated pipe, and the liquid pump's suction end is connected to one side of the water washing tank body through a water pumping assembly. The tank also includes: a filtration mechanism located at the bottom of the water washing tank body for filtering water discharged from the filter holes; and a guide frame fixed to the bottom of the placement plate for guiding the water discharged from the filter holes to the filtration mechanism.

[0006] The present invention provides an energy-saving water washing tank for a surface treatment production line, which, compared with the prior art, has the following beneficial effects, but is not limited to: To address the serious water waste in existing workpiece surface treatment washing processes, this device uses a washing tank as its base, with a placement plate to support the workpieces. A pump draws water from the tank via a pumping assembly, which then sprays it out through corrugated pipes and nozzles to clean the workpieces. During operation, workpieces to be cleaned are evenly placed on the placement plate. The pumping assembly draws out the cleaning water from the bottom of the washing tank and sprays it out through nozzles at the end of the corrugated pipes.

The filtered water enters the liquid pump 2 through the connecting pipe 71 and is then sprayed out from the nozzle 4; the filter element can be disassembled and replaced periodically to ensure the filtration effect; the fine filtration of the filter element prevents fine impurities from entering the liquid pump 2, reducing the failure rate of the liquid pump 2 by 70% and extending its service life by 2 times; the filtered water flows out from the nozzle 4 without clogging, the water pressure is stable, and the cleaning effect consistency is improved by 50%.

[0032] Optional, please refer to Figure 2 The bottom of the water washing tank 1 is also equipped with rollers 11 and a braking structure.

[0033] In this embodiment, the rollers 11 are casters. The four casters are evenly installed at the four corners of the bottom of the washing tank 1 via brackets 43. The wheel diameter is 80mm and the material is polyurethane. Each caster is equipped with a foot-operated brake structure, which can lock the rotation and direction of the wheel when braking. When pushing the washing tank 1, the casters can turn 360°, easily adjusting the position of the equipment. After moving to the target workstation, stepping on the brake structure locks the casters, preventing the equipment from sliding during the cleaning process.

When the nozzle 4 is not in use, it is inserted into the U-shaped groove of the bracket 43. The rubber buffer pad cushions the contact force between the nozzle 4 and the bracket 43, avoiding collision damage. When in use, it can be directly removed from the bracket 43, which is convenient. The nozzle 4 is stored in an orderly manner, avoiding damage or loss caused by random placement. The rubber buffer pad reduces friction and wear between the nozzle 4 and the bracket 43, resulting in better performance.

The placement plate 5 can be directly placed on the support strips 52. Two handles 53 are symmetrically installed at both ends of the placement plate 5. The surface of the handles 53 is provided with anti-slip texture for easy hand operation. When it is necessary to clean the bottom of the washing tank 1 or replace the placement plate 5, the placement plate 5 can be quickly removed by holding the handles 53 and lifting it up from the support strips 52. During installation, the placement plate 5 is aligned with the support strips 52 and placed down to complete the positioning, which is very convenient to use.
