The specific embodiment
Below by embodiment also by reference to the accompanying drawings, technical scheme of the present invention 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 is connected with the import of bellows 2.
In order to obtain good separating effect, the Inner chamber of bellows 2 is divided into three Room, be connected with corresponding air quantity adjustment doors respectively with the upper cover tri-Ma air outlet ， tri-Ma air outlet that communicates 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 dropping on sieve plate 21 is realized rapidly layering, makes light material upper, heavy material under, as long as and the air quantity of other two Room maintains layering.In order to reduce windage loss, the turning in interior three air channels of bellows 2 all adopts arc transition.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 three belows, Room is connected with corresponding air quantity adjustment doors 3; The partially rear position in 5 two outsides of vibrating bin is respectively 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 during higher than specified air pressure certain value, illustrate that sieve plate 21 seriously stops up, when air pressure is during lower than specified air pressure certain value, illustrate that air filter 19 seriously stops up, and should clean sieve plate or felt in time.
On vibrating bin 5, have three discharging opening one A, discharging opening two B, discharging opening three C, the qualified particle falling 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 slightly being blown afloat by wind moves to low side, through rear skewed slot, from discharging opening three C, flows out.Four springs 7 of vibrating bin 5 use are connected 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 is respectively 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 inclination angle increase and decrease 1 °, so the inclination angle of sieve plate 21 can be selected according to material properties and separating effect in 5 °, 6 °, 7 °, 8 °, 9 ° five grades.
Operation principle
When hybrid particles drops on the sieve plate 21 of gravity separation sieve from charging aperture I, under the effect of vibrating bin 5 medial compartment wind-force, realize rapidly layering, make heavy particle under, light and fine particle 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 slightly being blown afloat and fine particle leave compass screen surface and move and become tailing to low side, and flow out from outlet C through rear skewed slot; And heavier or larger particle can not be blown up, be attached on compass screen surface, because sieve plate 21 ovalize under the drive of vibrating motor 8 moves back and forth, make them to high-end movement, enter vibratory sieve 14, thereby realized the separation of weight particle.Can, according to the requirement of the purity of sorting and production capacity, 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, and the qualified particle of particle diameter leaks down from the mesh of screen cloth 24, from outlet A, flows out from outlet B.Outlet A, B, C are connected with the conveyer of below mutually by pipeline separately, selecting material to send in material storehouse separately.
This gravity separator Jing Mou Foundry Works is on probation, demonstrated gratifying separating effect, in 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 is 4-4.8t/M3,1900 ℃ of refractoriness >, expensive, price is about RMB4500 unit/t at present, and has up-trend.After casting falling sand, silica sand (the about RMB300 unit/t of the about 2.6t/M3 price of proportion) 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 there is 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 in the chrome ore reclaiming, still contain the impurity such as larger particles that the silica sand of larger proportion and silica sand and chrome ore are bonded together, if these impurity are not removed, its tensile strength is only 24% left and right of pure chrome ore tensile strength, can not continue to use.Certain Foundry Works adopts after the further sorting of this patent, and tensile strength reaches 70% left and right of pure chrome ore tensile strength, and after supplementing the new chrome ore of loss on the way, tensile strength has approached the tensile strength of pure chrome ore, can continue to use.
