The specific embodiment
Below by embodiment also by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Novel gravity separator as shown in the figure is comprised of parts such as air filter 19, air blast 1, bellows 2, air quantity section door 3, flexible pipe 4, vibrating bin 5, vibrating motor 8, gravity separation sieve 10, air uniform plate 11, case lid 12, soft envelope 13, vibratory sieve 14, spring 7 and frames 15.
Gu blower fan 1 adopts high pressure centrifugal ventilator, and its outlet links to each other with the import of bellows 2.
In order to obtain preferably separating effect, the inner chamber of bellows 2 is divided into three Room, communicate with three air outlets of loam cake respectively, three air outlets link to each other with corresponding air quantity adjustment doors respectively, according to the requirement of selection by winnowing, during air-supply, the air quantity of medial compartment can be slightly large, so that the hybrid particles that drops on the sieve plate 21 is realized rapidly layering, makes light material upper, heavy material is lower, as long as and the air quantity of other two Room is kept layering.In order to reduce windage loss, arc transition is all adopted at the turning in bellows 2 interior three air channels.Air filter 19, air blast 1 and bellows 2 are installed on the underframe of frame 15.
Vibrating bin 5 is corresponding three Room that are divided into also, and each personal flexible pipe 4 of air inlet of below, three Room links to each other with corresponding air quantity adjustment doors 3; The partially rear position in 5 two outsides of vibrating bin respectively is provided with vibrating motor 8, and mounted angle is 30 °; The medium position in 5 one outsides of vibrating bin is provided with air gauge 9, whether normal in order to observe the operating air pressure that gravity separation sieves between 10 belows and air uniform plate 11 tops, and estimate whether gravity separation sieve plate 21 or air filter 19 stop up, when air pressure is higher than specified air pressure certain value, illustrate that sieve plate 21 seriously stops up, when air pressure is lower than specified air pressure certain value, illustrate that air filter 19 seriously stops up, and should in time clean sieve plate or felt.
Have three discharging opening one A, discharging opening two B, discharging opening three C on the vibrating bin 5, the qualified particle that falls from vibratory sieve 14 mesh flows out from discharging opening one A; The bulky grain that exceeds standard on the net flows out from discharging opening two B through the place ahead skewed slot; Light or the fine particle that is slightly blown afloat by wind moves to low side, flows out from discharging opening three C through the rear skewed slot.Four springs 7 of vibrating bin 5 usefulness link to each other with frame 15, so during vibrating motor 8 work, vibrating bin 5 is also with corresponding frequency and amplitude vibration.The below of four springs 7 respectively is provided with an adjustment ring 6, in order to regulate the inclination angle of sieve plate 21, one of every increase and decrease, sieve plate once the inclination angle increase and decrease 1 °, so the inclination angle of sieve plate 21 can be selected in 5 °, 6 °, 7 °, 8 °, 9 ° five grades according to material properties and separating effect.
Operation principle
When hybrid particles drops on the sieve plate 21 of gravity separation sieve from the charging aperture I, under the effect of vibrating bin 5 medial compartment wind-force, realize rapidly layering, make heavy particle lower, the light fine particle that reaches is upper, because sieve plate 21 and vibrating motor 8 have suitable positive pitch, so under the effect of wind-force, the light silica sand that is slightly blown afloat and fine particle leave compass screen surface and move to low side and become tailing, and flow out from outlet C through the rear skewed slot; And heavier or larger particle can not be blown up, and is attached on the compass screen surface, because sieve plate 21 ovalize under the drive of vibrating motor 8 moves back and forth, makes them to high-end movement, enters vibratory sieve 14, thereby has realized the separation of weight particle.Can according to the requirement of purity and the production capacity of sorting, regulate air quantity, the inclination angle of sieve plate 21 or the exciting force of vibrating motor 8.
Enter the particle of vibratory sieve 14, the bulky grain that particle diameter exceeds standard slips into the place ahead skewed slot from screen cloth 24 tops, flow out from outlet B, and the qualified particle of particle diameter leaks down from the mesh of screen cloth 24, flows out from outlet A.Outlet A, B, C are connected with the conveyer of below mutually by pipeline separately, selecting material to send in separately the material storehouse.
This gravity separator is on probation through certain Foundry Works, demonstrated gratifying separating effect, in the casting industry in order to improve the surface quality of casting, be widely used chrome ore and make facing sand or core sand, the main dependence on import of chrome ore, proportion are 4-4.8t/M3, refractoriness＞1900 ℃, expensive, price is about RMB4500 unit/t at present, and up-trend is arranged.Behind the casting falling sand, silica sand (proportion approximately the 2.6t/M3 price approximately RMB300 unit/t) and chrome ore mix, in order to reclaim chrome ore, after mixed sand regeneration (removing the technique of sand grain surface resin), utilize chrome ore to have the characteristic of weak magnetic, adopt " non-ferromagnetic material recycling machine " to reclaim, although the rate of recovery of this machine can reach more than 90%, but still contain the impurity such as larger particles that the silica sand of larger proportion and silica sand and chrome ore are bonded together in the chrome ore that reclaims, if these impurity are not removed, its tensile strength only is about 24% of pure chrome ore tensile strength, can not continue to use.After certain Foundry Works adopted the further sorting of this patent, tensile strength reached about 70% of pure chrome ore tensile strength, and behind the new chrome ore that replenishes loss on the way, tensile strength can continue to use near the tensile strength of pure chrome ore.
