Description

Technical Field

[0001] The utility model relates to the technical field of dispersion kettles, in particular to a dispersion kettle for methanesulfonic acid. Background Art

[0002] Tin methanesulfonate is the main raw material for electroplating tin, electroplating tin alloy, chemical tin plating, chemical tin alloy plating, etc. Tin and tin alloy plating on metal surfaces is an important process in the production and manufacturing of electronic components, printed circuit boards, etc. With the rapid development of the electronics industry, the demand for tin methanesulfonate is growing. The combination of tin methanesulfonate and methanesulfonic acid is called the methanesulfonic acid electroplating system. Compared with the previous fluoroboric acid system and sulfuric acid system, it has great advantages: its electroplating wastewater is relatively easy to treat; the coating quality is stable and reliable; it can achieve high-speed electroplating and improve production efficiency, etc.

[0003] In the prior art, a Chinese patent with publication number CN216826216U discloses a dispersion kettle for methanesulfonic acid, which adopts the scheme of "comprising a reactor, a connecting rod fixedly connected to the middle part of the upper rear end of the reactor, a first motor fixedly connected to the front end face of the connecting rod away from the reactor, a third rotating shaft fixedly connected to the output end of the first motor, a feed pipe connected to the middle part of the left upper end of the reactor, first stirring columns evenly fixedly connected to the upper and lower ends of the left and right sides of the third rotating shaft, and the end faces of the first stirring columns away from the third rotating shaft are fixedly connected to the first stirring rods". This scheme solves the problems of low stirring efficiency, poor mixing degree caused by the inconvenience of swinging the reactor, and inconvenience of cleaning the raw materials adhered to the discharge pipe in the prior art through the above technical scheme.
