Description
Technical field
The utility model relates to the special equipment technical field that the precious metal smelting industry is used for the electrolytic silver powder washing and filtering.
Background technology
In the precious metal smelting silver preparing electrolysis process, silver powder goes out to contain a certain amount of silver nitrate electrolyte in the groove process in electrolysis, for guaranteeing the silver powder product quality, must the silver powder after the electrolysis be washed.At present, in the precious metal smelting industry, the main manual work of leaning on of silver powder washing, the silver powder that is about to out behind the groove places sink, injects distilled water immersion and manual stirring, cyclic washing, is neutral until the silver powder wash water.Washing back silver powder does not filter, and water content is higher, is about 7-10%%, needs just can be used for next process with hot-air oven baking 3-4 hour after the drying.In addition, the leaching requirement of washing usefulness is bigger, has not only increased the heavy silver work of sodium chloride, and the valuable metal loss is big, produces a large amount of wash waters simultaneously and gets into cleaning system, has increased cost for wastewater treatment.Therefore, there are shortcomings such as production efficiency is low, labour intensity is big, and the loss of valuable metal silver is many, and the slurry consumption is big in the conventional artificial operation, the needs of incompatibility modern production.
Summary of the invention
The purpose of the utility model is the deficiency that solves prior art; A kind of isolated plant that can carry out centrifugal filtration, washing to electrolytic silver powder is provided; To realize the full-automation of washing and filtering silver powder work, alleviate labor strength, improve the electrolytic silver powder detersive efficiency; Reduce production costs, improve metal recovery rate.
The purpose of the utility model realizes through following technical scheme:
A kind of full-automatic silver powder centrifugal filtration, wash mill, this device comprise support, be installed on the casing on the support and be installed on the cover at casing top; In casing, be provided with vertical central axis component, be set on the central axis component and with the outer drum that central axis component is fixedly connected, be arranged at the interior rotary drum in the outer drum; On the interior baseplane of outer drum, be uniformly distributed with and be provided with at least two vertical steady pins; Corresponding the bottom of interior rotary drum be uniformly distributed be provided with at least two recessed in the vertical pin-and-hole of rotary drum sidewall; Be inserted in steady pin through pin-and-hole interior rotary drum fixedly is fitted on the outer drum, constitute the centrifugal device of double rotating drum structure; On the drum inner wall filter bag is installed outside, on the sidewall of outer drum, offers the dehydration through hole that is uniformly distributed with; The charging hole and the clean-out opening of cavity two side roof parts between rotary drum and the outer drum in cover is provided with and leads to respectively are provided with outage at the bottom of shell that is positioned at below the outer drum, in the bottom of interior rotary drum discharge bucket are installed; The central shaft of central axis component connects with drive motors.
The utility model also is provided with the visor hole and observes lamp hole on cover.Casing, cover, outer drum, interior rotary drum adopt the 316L stainless steel to make, and alternate copolymer (Halar) material of surface spraying ethene, CTFE carries out preservative treatment.
The inner centrifugal device that adopts the double rotating drum structure of utility model; Not only can significantly improve the isolated by filtration effect, make the silver powder water content be reduced to 0.7%～0.8%, and can save the silver powder drying time by the 7%-10% under the manually-operated; Reduce energy consumption, production efficiency significantly improves.The silver powder that contains electrolyte gets into the centrifugal device that runs up and carries out filtration washing, can also effectively prevent in the silver powder fill process, directly falls into discharging opening because of silver powder proportion is excessive and causes the bottom to leak the material problem.Adopt the utility model, nitric acid electrolysis mother liquor can be realized circulating and recovering, and loss rate of metal can significantly reduce.The utility model adopts the automated production mode to substitute the work pattern of hand washing silver powder, can significantly reduce labor strength.The wash water consumption that laundry operation uses is 1/5th of traditional manually-operated use amount only also, can practice thrift the effluent purifying processing cost, alleviates environmental protection pressure.The harm that nitric acid electrolyte splashes the person is brought in the time of also can preventing manually-operated effectively improves operating environment.
Below in conjunction with accompanying drawing the utility model is done further explanation.
