Novel electrolytic degreasing bath

Abstract

The invention provides a novel electrolytic degreasing slot that is applied into the field of electrolytic degreasing production, and aims at overcoming the problems in original electrolytic degreasing that a common nozzle cannot agitate an electrolyte completely, and the removing of small bubbles that are generated on the surface of an electrode and the cleaning of solid dirt deposition are difficult. The novel electrolytic degreasing slot has following components: a degreasing slot (10) that is welded by steel plates and has a rubber lining, two sinking rollers (7), two turning rollers (6) that are installed outside the slot, a centrifugal pump (2) and a circulating slot (3) that are installed outside the slot, an overflowing opening that is opened on the top of the slot, a waste liquor storing slot that is externally connected, a heating pipe coil (4) of the electrolyte, a backflow tube (5), a band steel (9) that is used as the electrode, a mixing-flow nozzle (8) that is installed on a collecting tube at the bottom, and an array (11) of mixing-flow nozzles that are respectively installed at two sides of a wall of the degreasing slot. The novel electrolytic degreasing slot improves the uniformity degree of the electrolyte, ensures the purity of the electrolysis solution and raises electric conductivity. The bubbles and the solid dirt deposition of the electrolyte are all cleaned inside the circulating slot (3), thus lowering the operation difficulty for workers.

Description

technical field [0001] The invention belongs to the field of surface treatment production of steel plates in the metallurgical industry, in particular to the production field of electrolytic degreasing. Background technique [0002] The deep processing of steel plate, whether it is galvanized plate or color-coated plate, has better economic benefits than steel plate. It is a composite material. It not only has the excellent cold-formed processing performance of steel plate, but also has good corrosion resistance, durability and Good decoration, so the deep-processed galvanized steel sheet and color-coated steel sheet have a good application field, a broad market, and considerable economic benefits. The quality of the coating directly determines the performance of the product, and the quality of the surface treatment of the steel plate directly determines the adhesion of the product coating. Now the quality of the surface treatment of the steel plate directly depends on the e...

Problems solved by technology

[0004] In order to overcome the weak turbulent flow ability produced by the original degreasing nozzle, the electrolyte cannot be fully stirred, and the small bubbles with oil stains cannot be quickly removed, which reduces the degreasing work efficiency and affects the final degreasing effect, and the solid dirt deposit is difficult to clean. difficult problem, the present invention provides a new type of electrolytic degreasing tank, which can better improve the degreasing efficiency and facilitate the cleaning of the precipitation of solid dirt
