Description
Technical field
The present invention relates to filter feeding device field, be specifically related to a kind of Spongy Cadmium slip that zinc dust precipitation is obtained and carry out feed liquid separation, and the Spongy Cadmium after dehydration is added to the device of balling press and filters charging process.
Background technology
The Spongy Cadmium slip that zinc dust precipitation obtains needs filtering means dehydration to be then pressed into the agglomerate of certain specification, is convenient to next step use.In prior art: (adopt filter press, vacuum filter or natural filtration device) after the dehydration of Spongy Cadmium slurry filtration, adopt artificial scraper Spongy Cadmium to enter balling press, suppress agglomerating.Cause labour intensity large, loss of material is many, and Spongy Cadmium is oxidizable, and cadmium group presentation quality is not good.
Spongy Cadmium water content is larger, is sposh shape, and solid is short grained cadmium metal group, is not easy to filter.Useful component cadmium is wherein metal simple-substance, in malaria, can be oxidized, and reduces the quality of product.In production, must reduce contacting of Spongy Cadmium and air.Filtration and storage period, must avoid cadmium group to smash, and increase the contact area with air.Cadmium is a kind of noxious material, and the cadmium dirt sucking by respiratory tract can make human body poisoning, must reduce workman as far as possible and contact with the direct of cadmium.
The liquid-solid separation of existing Spongy Cadmium, send in the group's of pressure process and is generally stacking, artificial scraper, directly contacts with large quantity of air, and a dead lift can be smashed cadmium group, causes Spongy Cadmium oxidation, Quality Down.Workman and Spongy Cadmium close contact, cause poisoning hidden danger simultaneously.
Summary of the invention
The object of the invention is to, provide high, the laborsaving Spongy Cadmium of a kind of efficiency to filter feeding device and method, these apparatus and method have changed the mode of hand stock in the past, save labor cost, and loss of material is few.Utilize the charging process of this device, avoid Spongy Cadmium cruelly to leak in air for a long time, avoided the oxidation of Spongy Cadmium.
For above object, technical scheme of the present invention is:
Spongy Cadmium filters a feeding device, comprises the feed bin of upper and lower opening, the feed bin drip tray of surrounding whole bin bottom, the bin blanking pipe being communicated with the outlet of feed bin lower end and be placed in below balling press and surround the waste liquid pallet of whole balling press; The bottom sidewall of described feed bin is provided with a plurality of filter openings that flow out for waste liquid; Between described feed bin and bin blanking pipe, be provided with valve; Feed bin drip tray is connected with waste liquid pallet by drain pipe a, and waste liquid tray bottom is provided with the drain pipe b flowing out for waste liquid.
Described bin blanking pipe is preferably arranged over against the charging aperture of balling press.
Described feed bin upper end is preferably provided with feed bin lid or upper end and other equipment connections.
Lower end outlet, the mouth of pipe of drain pipe a and the mouth of pipe of drain pipe b of described feed bin are all preferably provided with filter screen.
Described filter screen is preferably stainless steel filtering net.
Described valve is pumping board valve.
Spongy Cadmium filters a charging process, take said apparatus as basis, and bin blanking pipe is arranged over against the charging aperture of balling press, and concrete steps are:
(1) mixture of Spongy Cadmium and liquid packs into after feed bin, and under Action of Gravity Field, liquid flows into feed bin drip tray from the filter opening of bin bottom, and Spongy Cadmium can not pass through filter opening, realizes Separation of Solid and Liquid; The liquid that storehouse drip tray is collected flows into waste liquid pallet by drain pipe a;
(2) Spongy Cadmium accumulation a certain amount of after, open pumping board valve, Spongy Cadmium enters balling press charging aperture through the gravity flow of bin blanking pipe; Close pumping board valve, balling press work, Spongy Cadmium compacting is agglomerating; The group's of pressure waste liquid flows into waste liquid pallet; The liquid that material waste liquid pallet is collected flows into storage tank by drain pipe b.
Operation principle of the present invention is: the mixture of Spongy Cadmium and liquid packs into after feed bin, and because of gravity factor, liquid leaches from the filter opening of bin bottom, and Spongy Cadmium can not pass through filter opening, realizes Separation of Solid and Liquid.And because the outlet of bin blanking pipe is over against balling press charging aperture or balling press mould, open pulling tray valve behind the door, Spongy Cadmium can flow in balling press or balling press mould, without man-handling of materials certainly.
Compared with prior art, advantage of the present invention is:
1, the present invention realizes cadmium silk floss from being dewatered to the agglomerating mechanically actuated that all realizes, and with by the reinforced mode of artificial manual manipulation, compared in the past, reduce continuous area and time contact with air of cadmium, minimizing is oxidized.
2, the present invention avoids the balling press man-handling of materials of feeding in raw material, and saves labour, and process is easy to realize automatic control, and loss of material is few, and allocative efficiency is high, labour intensity is little.
3, the present invention realizes lean cadmium solution (water that Spongy Cadmium is contained) and entirely reclaims, and reduces metal loss.
