A method for treating the inner wall of the water pipe of an enamel water tank and coating the liner

Abstract

The invention discloses an inner wall treatment method for a water pipe of an enamel water tank. The method comprises steps that a specially-made water pipe inner hole washing and grinding brush is adopted, a washing and grinding brush comprises a strip-shaped rod body and a rod handle with threads, a treatment liquid chamber is formed in the rod body, a treatment liquid for removing an oxide layer is arranged in the rod body, a treatment liquid outlet is formed in one side above the rod body, a steel wire brush formed by a thin steel wire with a certain length is arranged outside the rod body, the formed steel wire brush is tightly pressed and spirally fixed on the rod body, the treatment liquid is filled into the treatment liquid chamber from the treatment liquid outlet, a rod handle ofthe washing and grinding brush is mounted on an electric hand drill, the electric hand drill drives the washing and grinding brush to rotate at a high speed in the water pipe, under the action of centrifugal force of high-speed rotation, the treatment fluid is thrown out from the treatment fluid outlet and sprayed to an inner wall of the steel pipe to treat an oxide layer on an inner surface of the steel pipe, and then the steel wire brush rotating at a high speed grinds and removes the oxide layer and other foreign matter in the water pipe. The method is advantaged in that a very simple structural design is adopted, and the very good oxide layer removal effect is achieved.

Description

technical field [0001] The invention relates to the technical field of enamelling of solar water tanks, in particular to a method for treating the inner wall of a water pipe of an enamelled water tank and enamelling an inner tank. Background technique [0002] With the progress of the current society, energy conservation and emission reduction have become an important part of the development of today's society, and the rational and effective use of various clean energy sources such as solar energy and wind energy has become an important development direction. my country has a vast territory and abundant solar energy resources. Therefore, solar water tanks, which are traditional and simple solar energy utilization methods, have been used in vast areas of the country many years ago. The solar water tank can convert sunlight energy into heat energy, thereby heating the water in the tank from low temperature to high temperature, so as to meet the hot water use in people's life a...

Problems solved by technology

The entry of cold water and the outflow of hot water are realized through the water inlet and outlet pipes. There are often oxide layers and debris on the inner wall of the water inlet and outlet pipes. If no treatment is carried out, the oxide layer in the water pipes cannot achieve the expected treatment effect through the sandblasting operation of the inner tank. , which seriously affects the subsequent enamel quality and reduces the product life
