Apparatus and method of plate and frame filter press for hanger stripping production line

Abstract

The invention which relates to an apparatus and a method of a plate and frame filter press for a hanger stripping production line belongs to the mechanics. The apparatus of the plate and frame filter press for the hanger stripping production line is characterized in that: the apparatus comprises a stripping slot system, a buffer slot system, the plate and frame filter press, a percolate collecting slot, a stripping residue collecting vehicle and a lift platform; the stripping slot system comprises a plurality of stripping slots, and a plurality of stripping liquid lift pumps and stripping liquid lift pipelines which are used for conveying the stripping liquid; and the buffer slot system comprises a buffer slot, a diaphragm pump, and an upper liquidometer of the lift pump, a lower liquidometer of the lift pump, an upper liquidometer of the diaphragm pump and a lower liquidometer of the diaphragm pump which are used for controlling the liquid level. The method of the plate and frame filter press for the hanger stripping production line comprises the following steps: lifting the stripping liquid of a hanger; carrying out liquid level buffering on the stripping liquid of the hanger in the buffer slot; carrying out filter pressing on the stripping liquid in the buffer slot by the plate and frame filter press; and returning a new stripping liquid to the stripping production line to be recycled. According to the invention, the consumption amount of raw materials is saved, the production efficiency is improved, and the production cost is reduced.

Description

technical field

[0001] The invention relates to machinery, and is a method for processing the deplating solution of racks in the electroplating production process, in particular to a device and method for using a plate and frame filter press in a rack deplating production line. Background technique

[0002] As we all know, the last few processes on the electroplating automatic production line are the deplating of the hanger. During the deplating process, a large amount of deplating metal slag will be generated. If the metal slag accumulates too much, the plating tank must be cleaned. There are two traditional methods: One is to use the lock-type filter to filter circularly. This method is easy to block the filter, and the filter bag is cleaned and replaced frequently manually, resulting in waste of labor and materials; the other is to periodically reverse the tank, and the production line must be stopped every half a month or a month. For two days, intermittent maintenance i...
