Description
Technical field:
The present invention relates to foundry engieering, relate generally to foundry sand, the casting of particularly having used the selected recycling equipment of chromium sand.
Background technology:
When casting large-sized iron casting or steel-casting, to improve the surface quality of foundry goods, often adopt chromium sand for preventing the liquid metals infiltration.Chromium sand is the high-quality exotic material, main component is Cr2O3, it is a kind of neutral Modeling Material of high-quality, its coefficient of expansion is little, the thermal conductivity height, the effect that not only has good alkali resistance slag when contacting with molten metal bath, not with other metal oxide chemically reactive, and itself have the characteristics that solid phase is burnt tangerine, the foundry goods consecutive solidification can be promoted, the long-time heat effect of high-temperature liquid metal can be resisted, the infiltration of impedance high-temperature liquid metal, avoid cast(ing) surface to produce scab and crack defect, guarantee casting quality.But domestic chromite sand natural resources shortage mainly by import, costs an arm and a leg, be common quartz sand 20 surplus times.Therefore, general during practical application only as facing sand, how will carry out sorting with the chromium sand of crossing and the mixed sand of quartz sand, come out to utilize again with chromium sand is selected, be the important topic of a reality.
At present, domestic about the selected technology and equipment of chromium sand yet there are no the report and public, massive casting machinery plant of domestic a few family, provide product only to be chromium sand magnetic method roughing separation equipment as institutes such as Jiangsu Xi Nan casting machine factory, Luohe, Henan casting machine factory, Zhejiang casting machine designing institutees, all do not develop chromium sand picking equipment.External reported have only German GUT company and Italian IMf company can produce can be selected chromium sand screening installation, for magnetic method is roughly selected and the selected one chromium sand separator that combines of ebullated bed, wherein magnetic method is roughly selected identical with domestic coarse classifier product, and the selected part report of ebullated bed is not quite clear, and domestic do not have.It is reported that the major defect of external product is, the one, huge, complicated, the 2nd, cost an arm and a leg, the 3rd, selected effect is general.
Summary of the invention:
The present invention's purpose, relevant introduction according to external product, again with reference to the relative theory of domestic other industry field relevant granular material screening installation, development provides a kind of chrome sand sorter, different with the proportion of quartz sand according to chromium sand, the separating method of taking wind-force to combine with vibrations realizes that chromium sand is selected.
The foregoing invention purpose can so realize, a kind of chrome sand sorter, comprise air-blast device, have percussion mechanism three parts through airduct connection separating sieve, separating sieve, described separating sieve comprises that screen box 7, its middle part fixed grit 8, screen cloth are air compartment 9 down, screen box 7 front ends have charge door 26, be provided with strip material-dropping hole 28 between screen cloth one side and tank wall, under connect blanking funnel 33, air compartment 9 bottoms are provided with fresh air inlet and are connected with air intake flexible pipe 6, the air intake flexible pipe other end connects storage wind cabinet 5, and storage wind cabinet connects air-blast device through wind conveying pipe 4; Screen cloth 8 forms by the multilayer stainless (steel) wire is complex sintered.
Described air-blast device is by air filter 1, bottom air inlet mouth 2, top air-introduced machine 37 and tremble dirt mechanism 3 and constitute.
Described multilayer stainless steel mesh 8 is the 3-8 layer, and its top layer is wear-resisting filter screen 32, mesh 100--150 order; The 1-2 layer is main filter screen 31 under the top layer, mesh 100-250 order; Following all the other multilayers of main filter screen are for supporting time filter screen 30, mesh 8-50 order.
The percussion mechanism of described separating sieve is connected adjustable vibrations frame by actuating unit 25, driven pulley 24, with coaxial eccentric wheel 23, the connecting rod of eccentric wheel 22 of belt pulley and the latch plate 21 that fixes with adjustable vibrations frame and storage wind cabinet 5 respectively constitutes.
This chrome sand sorter adopts the existing rigidity of multilayer stainless steel sintered screen that intensity is arranged again, meets boiling, the requirement of jump sorting process; Air-blast device blows through screen cloth after adopting air filter with the air intake filter again, can effectively avoid the obstruction of dust-laden wind to screen cloth; Storage wind cabinet and screen box air compartment are set sieve end blast is kept in balance, make screen cloth evenly ventilative; The lifting of adjustable vibrations frame vertical, horizontal is adjustable, can realize that screen cloth tilts arbitrarily; Running part adopts the composite eccentric wheel can make the vibrations frame amplitude of oscillation multistage adjustable; It is frequently stepless adjustable that actuating unit adopts stepless speed-change motor that the vibrations frame is shaken; This machine according to material proportion difference, adopt wind-force and shake the grading principle that combines, design route is correct, constructs scientific and reasonablely, chromium sand is selected effective, rate of recovery height.This refiner also can be used for casting the sorting with the selected and abrasive sand of zircon sand.
