Description
Technical field
The present invention relates to filter the feeding device field, be specifically related to a kind of Spongy Cadmium slip that zinc dust precipitation is obtained and carry out feed liquid and separate, and the Spongy Cadmium after dewater adds device and the filtration charging process of balling press.
Background technology
The Spongy Cadmium slip that zinc dust precipitation obtains needs filtering means dehydration then to be 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, the easy oxidation of Spongy Cadmium, and it is not good that cadmium is rolled into a ball presentation quality.
The Spongy Cadmium water content is larger, is the sposh shape, and solid is short grained cadmium metal group, is not easy to filter.Useful component cadmium wherein is metal simple-substance, in malaria, oxidation can occur, and reduces the quality of product.Must reduce contacting of Spongy Cadmium and air in production.Filter and storage period must be avoided cadmium group is smashed, increase the contact area with air.Cadmium is a kind of noxious material, and the cadmium dirt that sucks by respiratory tract can make human body poisoning, must reduce the workman as far as possible and contact with the direct of cadmium.
The existing liquid-solid separation of Spongy Cadmium is sent to be generally stacking, artificial scraper in the group's of pressure process, directly contacts with large quantity of air, and a dead lift can be smashed cadmium group, causes the 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 that a kind of efficient is high, laborsaving Spongy Cadmium filters feeding device and method, these apparatus and method have changed the mode of hand stock in the past, the labor savings 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 purpose, technical scheme of the present invention is:
A kind of Spongy Cadmium filters feeding device, comprises the feed bin of upper and lower opening, surrounds the feed bin drip tray of whole bin bottom, the bin blanking pipe that is communicated with feed bin lower end outlet 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; Be provided with valve between described feed bin and bin blanking pipe; The feed bin drip tray is connected with the waste liquid pallet by drain pipe a, and the waste liquid tray bottom is provided with the drain pipe b of confession waste liquid outflow.
Described bin blanking pipe is preferably arranged over against the charging aperture of balling press.
Described feed bin upper end preferably is provided with feed bin lid or upper end and other equipment connections.
The lower end outlet of described feed bin, the mouth of pipe of drain pipe a and the mouth of pipe of drain pipe b all preferably are provided with filter screen.
Described filter screen is preferably stainless steel filtering net.
Described valve is the pumping board valve.
A kind of Spongy Cadmium filters charging process, take said apparatus as the basis, the bin blanking pipe is arranged over against the charging aperture of balling press, and concrete steps are:
(1) after the mixture of Spongy Cadmium and liquid was packed feed bin into, liquid flowed into the feed bin drip tray from the filter opening of bin bottom under Action of Gravity Field, and Spongy Cadmium can not pass through filter opening, realizes Separation of Solid and Liquid; The liquid that the storehouse drip tray is collected flows into the waste liquid pallet by drain pipe a;
(2) Spongy Cadmium accumulation a certain amount of after, open the pumping board valve, Spongy Cadmium enters the balling press charging aperture through the gravity flow of bin blanking pipe; Close the pumping board valve, balling press work, the Spongy Cadmium compacting is agglomerating; The group's of pressure waste liquid flows into the 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 is packed 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 over against balling press charging aperture or balling press mould, open pulling tray valve behind the door due to the outlet of bin blanking pipe, Spongy Cadmium can flow in balling press or balling press mould certainly, need not man-handling of materials.
Compared with prior art, advantage of the present invention is:
1, the present invention realizes the cadmium silk floss from being dewatered to the agglomerating mechanically actuated that all realizes, and with compared with the reinforced mode of artificial manual manipulation in the past, reduce continuous area and the time that contacts with air of cadmium, the minimizing oxidation.
2, the present invention avoids the balling press man-handling of materials of feeding in raw material, and saves the 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 the full recovery of lean cadmium solution (water that Spongy Cadmium is contained), reduces metal loss.
