Description

A kind of recycle device of zinc founding scum silica frost

Technical field

This utility model belongs to recycle device technical field, and in particular to a kind of recycling dress of zinc founding scum silica frost Put.

Background technology

Our company is constructed and put into operation from part of in August, 2008, and using Zinc hydrometallurgy process production technology, major product 0# zinc ingot metals are produced per year Up to 100,000 tons, Jing after company's enlarging in 2015, zinc ingot metal annual value of production reaches 12.5 ten thousand tons to value.In Zinc hydrometallurgy process production, most One procedure is cathode zinc founding afterwards, and cathode zinc is melted by we using frequency cored induction furnace complete set of equipments, Control for Kiln Temperature At 460-480 DEG C, the then Jing linear ingot castings casting qualified zinc ingot metal of output.Can output one when cathode zinc fusing is cast into zinc ingot metal The zinc dross of fixed number amount, up to more than 80%, the yield of scum silica frost is about 3%-the 5% of zinc ingot metal to zinc content, as its quantity of slag is big, contains Zinc is higher.Before 2015, this part zinc dross is transported to scum silica frost treatment process and carries out dry process.Zinc dross is through selecting block Sieved into a reciprocating sieve by feed bin Jing bucket elevators, Star-like unloader after zinc, the thin zinc gray (- 60 for sorting out Mesh) siftage Jing jigging conveyers, bucket elevator enter feed bin, and a part is calcined workshop use, another part export trade.Sieve The coarse granule of upper thing then enters dry type grid ball mill, and after ball milling, the screening of Jing secondary vibrations sieve, isolates three kinds of materials：- 60 mesh Thin zinc gray Jing jigging conveyer enters feed bin；The pack storage of+20 mesh zinc granules, whole export trades；The ash pack of-20 -+60 mesh crude zincs Storage, a part are used to prepare zinc powder, another part export trade.Pulsed jet cloth filter is employed in the flow process, air quantity is 60000m3/h, each feed inlet and outlet are equipped with the supporting smoke pipe that gathers dust, and each equipment junction sealing is preferable, and scene does not have dust The phenomenon flown upward, therefore working environment is good.But there is a shortcoming in the zinc dross handling process for below originally designing, be exactly Zinc dross after most of process has walked export trade, cannot sufficiently recycle, therefore how improve equipment and production technology, Improve metallic zinc direct yield, increase benefit, make zinc dross obtain sufficiently recycling just extremely urgent.

Utility model content

The purpose of this utility model is to provide a kind of recycle device of zinc founding scum silica frost, to solve above-mentioned background skill The problem proposed in art.

For achieving the above object, this utility model provides following technical scheme：A kind of recycling dress of zinc founding scum silica frost Put, including vibrosieve, dry type grid ball mill and secondary vibration sieve, a vibrosieve, dry type grid ball mill and Secondary vibration sieve is sequentially connected by pipeline.

Preferably, the secondary vibration sieve is set to ground floor sieve plate and second layer sieve plate, the sieve plate of the ground floor sieve plate Bore dia is 8mm, and one layer sieve plate and -60 purpose one layer screen cloth of the second layer sieve plate by aperture for 2mm are constituted.

Technique effect of the present utility model and advantage：The recycle device of the zinc founding scum silica frost, the vibrosieve after the transformation of the way The three kinds of materials for being sieved sufficiently are recycled in the case of the door that do not dispatch from the factory, and have been accomplished to make the best use of everything, increased enterprise Industry benefit；The zinc dross of zinc hydrometallurgy factory cathode zinc founding operation output is all recycled, environment is protected；Vibrosieve is not The method for remanufacturing of rust steel sieve plate is easy, and cost is relatively low.

Description of the drawings

Fig. 1 is composition connection diagram of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

This utility model provides a kind of recycle device of zinc founding scum silica frost as shown in Figure 1, including once vibrating Sieve, dry type grid ball mill and secondary vibration sieve, a vibrosieve, dry type grid ball mill and secondary vibration sieve is by pipe Road is sequentially connected, and the secondary vibration sieve is set to ground floor sieve plate and second layer sieve plate, and the sieve plate hole of the ground floor sieve plate is straight Footpath is 8mm, and one layer sieve plate and -60 purpose one layer screen cloth of the second layer sieve plate by aperture for 2mm are constituted.

In order to zinc dross is carried out optimized screening process, we change a social system the of the secondary vibration sieve of scum silica frost treatment process Sieve plate bore dia is changed to 8mm by 2mm before by one layer of sieve plate, and second layer sieve plate is constant, and still a layer by aperture for 2mm is sieved One layer of screen cloth composition of plate and -60 mesh；The granularity of oversize more than 8mm is increased to into, oversize is reduced with than before A lot, intermediate material has very big increase；Oversize zinc granule accounts for the 5% of total amount, its lead and iron tramp constituent content compared with It is high；Therefore, this part zinc granule can be allocated in kirsite and production of zinc ingot, is fully used；- 60 mesh siftage (accounting for the 64.5% of total amount) fluorine-containing, chlorine is higher, then be transported to the Zinc Oxide workshop of new enlarging in 2015, together with secondary zinc oxide Allocate rotary kiln high temperature fluorine removal, chlorine into, so, the zinc metal of the thin zinc gray of -60 mesh all can be recycled, and greatly reduce life Cost is produced, enormous benefits are increased；Screening intermediate material zinc granule (accounting for the 30.5% of total amount) out, its granularity is little, Surface area is big, and in fusion process, easily oxidation becomes Zinc Oxide, therefore can transport electric furnace zinc powder operation in factory to, with secondary zinc oxide Jing electric furnaces are coordinated to make metal zinc, in practice it has proved that, the metal zinc complies fully with the standard that remove impurity link is used, and has accomplished thing Its use, greatly reducing the fund of outsourcing zinc powder to the greatest extent；The technique productions are not dispatched from the factory by door zinc dross with less investment Be converted into three kinds of materials, but and oneself digestion, be the ideal technology of potentiation.

Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to Utility model, although being described in detail to this utility model with reference to the foregoing embodiments, for those skilled in the art For, which still can be modified to the technical scheme described in foregoing embodiments, or to which part technical characteristic Equivalent is carried out, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc., Should be included within protection domain of the present utility model.
