Silver plating production line iron powder solution online mixed supply mechanism and supply method

Abstract

The invention discloses a silver plating production line iron powder solution online mixed supply mechanism, which comprises a sealed mixed container, a material conveying pump and a filter, wherein an iron powder material supply mechanism and a pure water pipe are arranged on the top of the mixed container; a plurality of air inlets communicating with an external compressed air source are formed in the bottom of the mixed container; an air escaping hole is formed in the top of the mixed container; the material conveying pump is used for pumping out suspension in the mixed container; the filter is connected with the output end of the material conveying pump and is used for removing large-particle iron powder. The sealed mixed container is used for realizing the use immediately after the preparation; the volume of the mixed container can be greatly reduced; the volume of 8 to 10L can generally meet the requirements; the space occupation is reduced; the pneumatic stirring mixing is used; the waste can be reduced; the generation of precipitates is prevented; in addition, after the machine halt, the injected pure water can be directly used for being matched with the compressed air for cleaning; the operation and the control are convenient; the sealed container is used; the water sputtering and the iron powder oxidation can be prevented.

Description

technical field [0001] The invention relates to the technical field of mirror production, in particular to an online mixing supply mechanism and supply method for iron powder solution in a silver plating production line. Background technique [0002] The copper layer of the reflector is the key film layer between the silver film and the paint film. The quality of the copper film directly affects the service life of the silver film and the paint film, thus affecting the service life of the overall reflector. [0003] In the traditional copper plating process, the iron powder solution is prepared by simply adding iron powder and water to a plastic bucket of tens of liters and stirring the motor. There are problems such as uneven stirring, too much stirring, causing waste, easy precipitation of iron powder, and damage to the barrel wall. The residual iron powder above the water level is easy to oxidize to form impurities, the iron powder nozzle is easy to block, and the prepara...

Problems solved by technology

[0002] The copper layer of the reflector is the key film layer between the silver film and the paint film. The quality of the copper film directly affects the service life of the silver film and the paint film, thus affecting the service life of the overall reflector.

[0003] In the traditional copper plating process, the iron powder solution is prepared by simply adding iron powder and water to a plastic bucket of tens of liters and stirring the motor. There are problems such as uneven stirring, too much stirring, causing waste, easy precipitation of iron powder, and damage to the barrel wall. The residual iron powder above the water level is easy to oxidize to form impurities, the iron powder nozzle is easy to block, and the preparation device is difficult to clean, which seriously affects the quality of the copper film and increases the production cost.
