The specific embodiment
Through embodiment and combine accompanying drawing, technical scheme of the present invention is further specified below.
Embodiment:
Novel gravity separator as shown in the figure is made up of parts such as air filter 19, air blast 1, bellows 2, air quantity joint 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 Fan a high pressure centrifugal fan, with its outlet connected to the inlet air box 2.
In order to obtain a better separation efficiency, bellows cavity is divided into three rooms 2, respectively, and atop the three Ma outlet connected, three Ma, respectively, with the corresponding outlet air volume control gate is connected, according to the requirements of winnowing, air , the middle chamber of the air flow may be slightly larger, so falls on sieve 21 layered mixed particles quickly realize that the material in the light, heavy material in the next, while the other two-compartment air flow as long as you can maintain stratification.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.
Also corresponding three Room that are divided into of vibrating bin 5, each personal flexible pipe 4 of air inlet of below, three Room links to each other with corresponding air quantity adjustment doors 3; The position, back partially 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 whether estimation gravity separation sieve plate 21 or air filter 19 stop up, when air pressure is higher than specified air pressure certain value; Explain that sieve plate 21 seriously stops up; When air pressure is lower than specified air pressure certain value, explain that air filter 19 seriously stops up, and should in time clean sieve plate or felt.
Vibratory sieve 14 is positioned at the front end of vibrating bin 5, and mounted angle is 10 °, and its structure is basic identical with the structure of gravity separation sieve 10, and different is to adopt the individual layer high-strength stainless steel mesh 24 with some, the larger particles impurity that exceeds standard in order to removing.
Have three discharging opening one A, discharging opening two B, discharging opening three C on the vibrating bin 5, the qualified particle that from vibratory sieve 14 mesh, falls flows out from discharging opening one A; Exceeding standard on the net, skewed slot flows out from discharging opening two B bulky grain through the place ahead; Light or the fine particle that is blown afloat slightly by wind moves to low side, and skewed slot flows out from discharging opening three C through the rear.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 correspondent 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.
Case lid 12 is fixed on the top of frame 15 through two cross bars 17 and the two pairs of support bars 18.The top of case lid 12 is provided with the charging aperture I, and two sides are provided with openable observation window, and front and back are provided with the dust flue that links to each other with the dust pelletizing system pipeline, and the place ahead is provided with overhead door, can when maintaining, dig.5 of case lid 12 and vibrating bins are provided with soft envelope 13, overflow with dust protection.
Operation principle
Hybrid particles drops on the 21 last times of sieve plate of gravity separation sieve from the charging aperture I; Under the effect of vibrating bin 5 medial compartment wind-force, realize layering rapidly, make heavy particle, gently reach fine particle last down; Because sieve plate 21 and vibrating motor 8 have suitable positive pitch; So under the effect of wind-force, light silica sand that is blown afloat slightly and fine particle leave compass screen surface and move to low side and become tailing, and skewed slot flows out from outlet C through the rear; And heavier or bigger particle can not be blown up, and on compass screen surface, because sieve plate 21 ovalize under the drive of vibrating motor 8 moves back and forth, they is moved to high-end, gets into vibratory sieve 14, thereby has realized the separation of weight particle.Can regulate air quantity, the inclination angle of sieve plate 21 or the exciting force of vibrating motor 8 according to the requirement of the purity and the production capacity of sorting.
Get into 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, from outlet B, flow out, and the qualified particle of particle diameter leaks down from the mesh of screen cloth 24, from outlet A, flows out.Outlet A, B, C are connected with the conveyer of below through pipeline separately mutually, selecting material to send in the material storehouse separately.
This gravity separator is on probation through certain Foundry Works, has demonstrated gratifying separating effect, in the casting industry in order to improve the surface quality of casting; Widely-used chrome ore is made facing sand or core sand, and the main dependence on import of chrome ore, proportion are 4-4.8t/M3; Refractoriness＞1900 ℃; Cost an arm and a leg, price is about RMB4500 unit/t at present, and up-trend is arranged.Behind the casting falling sand, silica sand (the about RMB300 of the about 2.6t/M3 price of proportion unit/t) mix, in order to reclaim chrome ore with chrome ore; After mixed sand regeneration (removing the technology of sand grain surface resin); Utilize chrome ore to have the characteristic of weak magnetic, adopt " non-ferromagnetic material recovery machine " to reclaim, though the rate of recovery of this machine can reach more than 90%; But still contain silica sand and the silica sand of larger proportion and the impurity such as larger particles that chrome ore is 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.
