Abstract

The invention discloses a tin stripping solution recycling and processing device. The sedimentation slant plate of the sedimentation support assembly is arranged on one side of the sedimentation tank, the removal support frame of the removal component is slidingly connected with the sedimentation tank, and the removal support plate is slidingly connected with the removal support frame. The protective cover is connected to the take-out support rod in rotation, the first screw motor is installed on one side of the sedimentation tank through the sliding support seat, the support guide rails are set on both sides of the sedimentation tank, and the extension rod is slid on the top, and the extension rod is driven by the second screw motor. A scraper is arranged on the extension rod. The second screw motor drives the extension rod and the scraper to collect the sediment on the rocking plate, so that the sediment can enter the take-out support plate, and then rotate the protective cover to protect the sediment, and the first screw motor drives the take-out support frame to move up and slide The support plate is taken out to take out the sediment, so that the sediment can be scraped off more easily, so that the sediment on the shaking plate can be collected and taken out conveniently, and the working efficiency is improved.

Description

technical field

[0001] The invention relates to the field of wastewater treatment, in particular to a tin stripping liquid recovery and treatment device. Background technique

[0002] Tin stripping water, also known as tin stripping liquid, is one of the main chemical materials used in the production of printed circuit boards. It is used for the removal of tin plating, tin-lead alloy plating and tin solder joints. According to the different main components, tin stripping water can be divided into three types: fluoride type, which is composed of hydrofluoric acid, fluoride salt, peroxide, etc. The economic indicators are all poor, and it has become an obsolete formulation. Now it is used less at home and abroad; nitric acid type tin stripping water is composed of nitric acid, ferric nitrate, corrosion inhibitor, surfactant, nitrogen oxide inhibitor, complexing agent, etc. Composition, the concentration of nitric acid is generally 20% to 25%, which has the characteristics of ...
