Embodiment 1

[0051] This embodiment provides a water treatment environmental protection device for cleaning tinplate, such as figure 1 and figure 2 As shown, it includes: a cleaning cycle mechanism, a plate conveying mechanism 2, a recovery processing mechanism 3 and a spraying mechanism.

[0052] Among them, the cleaning cycle mechanism includes a primary cleaning tank 11, a secondary cleaning tank 12 and a final cleaning tank 13. Cleaning water circulates in any one of the cleaning tanks to clean the surface of the board; the board conveying mechanism 2 drives the board to rotate through the primary The cleaning tank 11, the secondary cleaning tank 12, and the final cleaning tank 13 are output along the outlet side of the final cleaning tank 13; one end of the recycling mechanism 3 is connected to the cleaning water in the primary cleaning tank 11, and one end is connected to the plating tank 4. Form a recovery closed system; the recovery processing mechanism 3 includes a first-stage p...

Abstract

The invention discloses an environmentally-friendly water treatment device for tinned plate cleaning. The device comprises: a cleaning circulation mechanism least provided with a primary cleaning tankand a final cleaning tank, wherein cleaning water circulates in any cleaning tank to clean the surfaces of plates; a plate conveying mechanism for driving the plates to rotatably go through the primary cleaning tank and the final cleaning tank in sequence, wherein the plates are output along the outlet side of the final cleaning tank; and a recovering and processing mechanism communicated with the cleaning water in any cleaning tank at one end and connected with a plating tank at the other end to form a closed recovering system, wherein the recovering and processing mechanism comprises a first-stage pump and an evaporator which are sequentially communicated, the outlet side of the evaporator is provided with an outputted plating solution outlet and a condensed water outlet, and the plating solution outlet is communicated with the plating tank. The arranged recovering and processing mechanism makes an evaporation tray recover a recoverable tin solution and an additive in the tinning plating solution, and returns the recovered components into the plating tank, so the cost is greatly saved, and the waste of resources is reduced.

Description

technical field [0001] The invention relates to the technical field of cleaning electroplating workpieces, in particular to a water treatment and environmental protection device for cleaning tinned plates. Background technique [0002] Tinplate (also known as tinplate) refers to a cold-rolled thin steel plate coated with a layer of extremely thin metal tin on both sides. Annealing, smoothing, edge trimming, and then cleaning, electroplating, reflow, passivation treatment, oiling, and then cutting into finished tinplate sheets. The tin plating used for tinplate is high-purity tin (Sn>99.8%). It combines the hardness and strength of steel with the weldability, corrosion resistance and bright appearance of tin. Tinplate has the advantages of being odorless, non-toxic, light in weight, and easy to process and shape. Printing different patterns can also beautify the product, so it has been widely used in the food can industry, electronic devices, chemical paint and other ind...
