AI Technical Summary

Technical Problem

Existing spraying equipment struggles to achieve a coating thickness of over 300 micrometers on the inner tank of a water heater in a single application, and reduced spray gun voltage leads to poor spraying results, especially at the inner cavity and joints of the tank, where leakage or corrosion is likely to occur.

Method used

The system employs a spraying line platform, a constant voltage spraying power supply assembly, first and second spraying assemblies, and a clamping assembly. Through constant voltage electrostatic spraying technology, it ensures stable spraying voltage. Combined with a straight nozzle and a super corona ring, it achieves comprehensive spraying of the inner liner, especially uniform coating of the inner cavity and interfaces.

Benefits of technology

It improves the coating thickness and powder coverage, avoids powder accumulation at the inner tank interface, enhances coating efficiency and comprehensiveness, and extends the service life of the water heater.

Abstract

This utility model provides a spraying device for the inner tank of a water heater, including a spraying line platform body and a spraying mechanism disposed on the spraying line platform. The spraying mechanism includes a first spraying component, a second spraying component, a clamping component, and a driving and moving component. The first spraying component and the second spraying component are disposed opposite each other on both sides of the spraying line platform. The clamping component is used to clamp and fix the workpiece to be sprayed. The spraying device for the inner tank of a water heater provided by this utility model can spray the workpiece on a first azimuth surface when spraying the inner tank of the water heater. The second spraying component can spray the workpiece on a second azimuth surface, ensuring the powder coverage and coating thickness, ensuring the comprehensiveness of the inner tank-shaped workpiece spraying, avoiding powder accumulation at the water inlet and outlet interfaces, and improving the spraying efficiency of the inner tank-shaped container.
