Abstract
The utility model relates to a device for preparing nickel dihydroxide powder from waste nickel meshes. The device is characterized in that: the device comprises an electrolytic tank (1), wherein the electrolytic tank (1) is connected with a mixing tank (2) through a pipeline, the mixing tank (2) is connected with an atomizer (3) through the pipeline, a nozzle (3.1) is arranged at the tail end of the atomizer (3) and is arranged above a reactor (4), and the bottom of the reactor (4) is connected with a centrifugal separating machine (5). When the device for preparing the nickel dihydroxide powder from the waste nickel screen sheets is adopted, the waste nickel meshes are put into the electrolytic tank for electrolyzation, are then put into the mixing tank to mix with liquid, and are sprayed into the reactor by the atomizer to obtain precipitates; the nickel dihydroxide powder can be obtained by drying the precipitates which is separated by the centrifugal separating machine; and therefore pollution on the environment is avoided, and nickel resources are also saved.
Description
Technical field
The utility model relates to a kind of the utilization and discards the device that the nickel screen sheet is processed nickel oxyhydrogen powder; Be used for that the discarded nickel screen sheet that the nickel screen production process produces is carried out electrolysis, mixing and atomizing and spray into reaction tank, pull out at last and obtain the nickel oxyhydrogen powder powder after the extraction throw out is dried.
Background technology
China is maximum in the world textile printing and dyeing producing country, needs every year to consume a large amount of printed nickel nets, and the nickel screen of can printing and dyeing but exists huge wasting of resources phenomenon.As everyone knows, in the nickel screen production process, can produce two kinds of wastes, a kind of is the electroplating wastewater that contains chromium, nickel, and another kind is discarded nickel screen sheet.
The discarded nickel screen sheet that in the past in the nickel screen production process, produced is directly abandoned, yet the nickel content in the discarded nickel screen sheet is bigger, directly abandons and has not only polluted environment, also nickel resources has been caused huge waste.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provide a kind of and prevent the pollution of the environment, and the discarded nickel screen sheet of utilization that has reclaimed nickel resources is processed the device of nickel oxyhydrogen powder.
The purpose of the utility model is achieved in that
The discarded nickel screen sheet of the utility model utilization is processed the device of nickel oxyhydrogen powder; Comprise electrolyzer; Said electrolyzer links to each other with mixing pit through pipeline, and said mixing pit links to each other with spraying gun through pipeline, and the end of said spraying gun is provided with nozzle; Said nozzle is positioned over the top of reactor drum, and the bottom of said reactor drum links to each other with separating centrifuge.
Compared with prior art, the beneficial effect of the utility model is:
The device that the discarded nickel screen sheet of this utilization is processed nickel oxyhydrogen powder will be discarded the nickel screen sheet and put into behind the electrolyzer electrolysis and get into mixing pit again and mix liquid; Be atomized device subsequently and spray into and obtain throw out in the reactor drum, isolate the throw out after drying by separating centrifuge and just can obtain the nickel oxyhydrogen powder powder.So not only avoid the pollution of environment, also practiced thrift nickel resources.
Description of drawings
Fig. 1 processes the structural representation of the device of nickel oxyhydrogen powder for the discarded nickel screen sheet of the utility model utilization.
Wherein: electrolyzer 1, mixing pit 2, spraying gun 3, nozzle 3.1, reactor drum 4, separating centrifuge 5.
Embodiment
Referring to Fig. 1; The utility model relates to a kind of the utilization and discards the device that the nickel screen sheet is processed nickel oxyhydrogen powder, comprises electrolyzer 1, and said electrolyzer 1 links to each other with mixing pit 2 through pipeline; Said mixing pit 2 links to each other with spraying gun 3 through pipeline; The end of said spraying gun 3 is provided with nozzle 3.1, and said nozzle 3.1 is positioned over the top of reactor drum 4, and the bottom of said reactor drum 4 links to each other with separating centrifuge 5.
After discarded nickel screen sheet was put into electrolyzer 1, adding nitric acid and ydrogen peroxide 50 were done catalysis in electrolyzer 1, form nickelous nitrate through electrolytic mode; Feed subsequently in the mixing pit 2; And in mixing pit 2, add Xiao Suangu, ammonia, sodium hydroxide and be mixed into mixed solution, squeeze in the spraying gun 3 by pump subsequently, and spray into the reactor drum 4 from nozzle 3.1; Keep the reaction solution pH value between 10-11; Temperature is to obtain throw out behind 50 degree, by separating centrifuge 5 throw out is isolated again, at high temperature just can obtain the nickel oxyhydrogen powder powder after the drying at last.
Claims (1)
1. one kind is utilized discarded nickel screen sheet to process the device of nickel oxyhydrogen powder; It is characterized in that: it comprises electrolyzer (1); Said electrolyzer (1) links to each other with mixing pit (2) through pipeline, and said mixing pit (2) links to each other with spraying gun (3) through pipeline, and the end of said spraying gun (3) is provided with nozzle (3.1); Said nozzle (3.1) is positioned over the top of reactor drum (4), and the bottom of said reactor drum (4) links to each other with separating centrifuge (5).
