The special jigging machine of a kind of sorting oil shale
Art
The utility model relates to a kind of preparation equipment, especially relates to a kind of special jigging machine for sorting oil shale.
Background technology
Oil shale is a kind of liquefaction resource, and its storage capacity is several times of coal saving amount, and along with the minimizing of petroleum resources, exploitation and the utilization of oil shale are brought into schedule gradually.At present, all useless coal washing technique in oil shale and equipment both at home and abroad, because oil shale proportion is many at 2 ~ 3 gram per centimeters
3between, with spoil proportion closely, tradition jigging machine can not carry out effective sorting to it, also not can be used in the jigging machine of oil shale sorting up till now, how to improve existing jigging machine to adapt to one problem that oil shale washing has become these those skilled in the art.A kind of oil shale preliminary election discharge refuse--the distillation process that disclosed in 19 days September in 2014 of China national Department of Intellectual Property, CN104194814A is contained, with jigging machine, discharge refuse is carried out to oil shale although be referred to, but the not open jigging machine for oil shale discharge refuse of this patent and technology, and up to the present do not see the report of any use jigging machine washing oil shale yet.Solve oil shale jigging machine sorting problem, need to overcome double above, valuable mineral and mine tailing difference in specific gravity of bed proportion in traditional jigging technology and be less than the stubborn problem such as 0.5.
Summary of the invention
The purpose of this utility model is to provide a kind of jigging machine oil shale being carried out to sorting, and this equipment once can sub-elect spoil, chats, concentrate three kinds of products, has treating capacity large, the feature that the rate of recovery is high.
The technical solution of the utility model is summarized as follows:
The special jigging machine of a kind of sorting oil shale of the present utility model, comprise existing air pulsating jig, this jigging machine is by spoil section bellows, chats section bellows, and spoil section body, the organization of chats section, wherein spoil section body and chats section body are 3 cell structures, spoil section bellows and chats section bellows are absolute construction, and spoil section bellows sieve lower air chamber respectively by first in airduct and spoil section body, the lower air chamber of second sieve, the lower air chamber of 3rd sieve is connected, chats section bellows sieve lower air chamber respectively by first in airduct and chats section body, the lower air chamber of second sieve, the lower air chamber of 3rd sieve is connected, each airduct is respectively equipped with control valve.
The inclination angle of described sorting oil shale special jigging machine spoil section sieve plate is 3-5 degree, and the inclination angle of chats section sieve plate is 2-4 degree.
Described sorting oil shale special jigging machine spoil section cell body, chats section cell body and spoil section discharge road, chats section discharge are all inlaid with removable wearing plate in road.
The difference in height of described sorting oil shale special jigging machine spoil section sieve plate exit end face and described chats section sieve plate entrance face is at 200 to 300 millimeters.
Air feed blast in described sorting oil shale special jigging machine spoil section bellows is 0.04 ~ 0.05 MPa, and the air feed blast in chats section bellows is 0.03 ~ 0.04 MPa.
Compared with the prior art the utility model, fully shows following advantage:
(1) can realize the industrialization sorting to oil shale mine, changing current technology can not the present situation of sorting oil shale mine;
(2) under the acting in conjunction of high inclination-angle sieve plate and high blast, treating capacity strengthens, and improves the disposal ability of the unit are of jigging machine;
(3) under the effect of different blast, jigging machine sharpness of separation improves.
Adopt the special jigging machine of sorting oil shale of the present utility model to carry out oil shale sorting, can obtain the common jigging machine of existing tradition can not effect, be jigging machine brand-new in a kind of washup industry.

Detailed description of the invention
The special jigging machine of a kind of sorting oil shale that the utility model provides, is further described below in conjunction with Fig. 1:
Embodiment 1, in Fig. 1, the special jigging machine of a kind of sorting oil shale, it comprises existing air pulsating jig, it is by spoil section bellows 1, chats section bellows 29, and spoil section body 30, chats section body 31 forms, wherein spoil section body 30 and chats section body 31 are 3 cell structures, spoil section bellows 1 and chats section bellows 29 are absolute construction, and spoil section bellows 1 have air inlet 2, exhaust outlet 3, spoil section bellows 1 are respectively by airduct 4, 5, 6 sieve lower air chamber 10 with first in spoil section body 30, the lower air chamber 11 of second sieve, the lower air chamber 12 of 3rd sieve is connected.Chats section bellows 29 have air inlet 28, exhaust outlet 27, chats section bellows sieve air chamber 13, second down respectively by airduct 7,8,9 and first in chats section body 31 and sieve air chamber 14, the 3rd to sieve air chamber 15 to be connected, and each airduct is respectively equipped with control valve.The outlet of spoil section body 30 is connected with chats section body 31 ingress adapter.
During the present embodiment work, join the oil shale raw ore in described spoil section ragging, under the pulsation water body of air chamber 10,11,12 generation and the effect of spoil section sieve plate 23, complete the loose of bed and conveying, and carry out layering by density difference, the lower floor's spoil after sorting, behind spoil section discharge road 16 and spoil section waste rock discharge device 17, thoroughly sieve thing down with sieve to mix, discharge from spoil section discharge gate 18; Upper strata product after sorting, comprise concentrate and chats etc., chats section jigging machine machine tool layer cell body 24 is entered into from chats section feeding mouth, under the pulsation water body of air chamber 13,14,15 generation and the effect of chats section sieve plate, complete the loose of bed and conveying by wind and water, carry out sorting again by density difference, lower floor's chats product after sorting, after chats section discharge device 21 and chats section discharge road 20, thoroughly sieve product down with sieve and mix, discharge from chats section discharge gate 19; Concentrate product after sorting, discharges from cleaned coal discharge gate 26.In assorting room, adjust and control the blast in spoil section bellows 1 and chats section bellows 29 as required respectively, guarantee spoil section bed cell body 22 and chats section bed cell body 24 have a best shatter value respectively.The shatter value of spoil section bed cell body 22 different parts, can be adjusted by the fine setting of supply gas pressure and flow in the air chamber 10,11,12 of corresponding position, in air chamber 10,11,12, the fine setting of supply gas pressure and flow realizes respectively by the control valve be located on airduct 4,5,6; The shatter value of chats section bed cell body 24 different parts, can be adjusted by the fine setting of supply gas pressure and flow in the air chamber 13,14,15 of corresponding position, in air chamber 13,14,15, the fine setting of supply gas pressure and flow realizes respectively by the control valve be located on airduct 7,8,9.Also as required, can adjust the displacement size of spoil or chats at any time in work, the spoil that guarantee is discharged and concentrate reach the requirement needing precision, thus complete the jigging sorting work of raw ore.
Based on same principle and method, the inclination angle of the jigging machine spoil section sieve plate 23 in such as Fig. 1 can be set to 3-5 degree by the utility model, and the inclination angle of chats section sieve plate 25 is set to 2-4 degree.
Based on same principle and method, the utility model can all be inlaid with removable wearing plate by spoil section bed cell body 22, chats section bed cell body 24 and the spoil section discharge road 16 in such as Fig. 1, chats section discharge road 20.
