Tin recovery device with hypersorber

Abstract

The invention discloses a tin recovery device with a hypersorber. The tin recovery device comprises a device body which is arranged in a wave-soldering furnace and used for tin recovery. The hypersorber with the specific gravity smaller than that of a tin mixture in the furnace is arranged in the device body. A slag overflow opening is formed in one side of the upper portion of the device body. A tin outlet is formed in the bottom of the device body. Stirring devices are arranged in the device body and comprise a plurality of stirring shafts, stirring blades, extrusion wheels and crushing blades, and the stirring blades, the extrusion wheels and the crushing blades are sequentially mounted on the stirring shafts. The multiple stirring devices are connected with a drive motor through a gear linkage box, wherein the drive motor is arranged above the device body. The hypersorber runs in the device and is isolated from a master batch in the tin furnace. Due to the fact that the hypersorber is small in specific gravity and floats on the device, and the tin outlet is located in the bottom of the device, the hypersorber is not mixed with a tin material in the wave-soldering furnace, the tin material is not contaminated, and a furnace container and a welded electronic element are not damaged; a crushing agent, an adsorption agent, a dispersion agent and an aqueous solution in the hypersorber are mainly used for oxidization, physical damage and adsorption on tin, and the hypersorber cannot cause corrosion damage to products and the device; and according to the scheme, convenience, high efficiency and safety are achieved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a tin recovery device with an active adsorbent. Background technique [0002] Tin is a rare and expensive heavy metal. With the continuous development of economic construction and its industry, the consumption is increasing year by year. The amount of tin waste in the production process of tin industry or in daily life is also increasing, while the resource reserves are decreasing year by year. Therefore, in order to To meet the rapid development of the tin industry and the balance between supply and demand, the tin recycling industry has gradually become an important direction for the development of the tin industry. With the development of the economy, the development of recycled tin has attracted global attention. [0003] The generation of tin slag in the wave furnace will lead to poor solder fluidity, pollute electronic components, and generate welding defects at the same ...

Problems solved by technology

[0004] The disadvantages of commonly used reduction and anti-oxidation include: the use of nitrogen is expensive; the use of oil will cause equipment pollution, destroy equipment cleaning and long-term operation; use powder to cause dust pollution and odor, which has an impact on people and the environment

The above methods can also cause corrosion of equipment, especially the furnace, and sometimes it will be polluted by soldered electronic components
