Description
Technical field
The utility model belongs to the screening plant field, particularly a kind of screening plant for screening high-adhesiveness material.
Background technology
Large-scale linear vibrating screen is a kind of important vibrating machine in the industrial production, and it is the equipment that material is carried out sizing screening by particle diameter.This kind screening plant is mainly by putting on the vibration of sieve nest, makes by sieve material loosening and saturating sieve, realizes screening, classification dehydration, de-mediated etc. to material, now is widely used in the industries such as mine, metallurgy.
In recent years, along with high grade iron breeze resource progressively disappears, the Iron Ore Powder that contains rare earth element in the low-grade iron-bearing mineral becomes the important source that smelts the high added value molten iron.And these Iron Ore Powder that contain rare earth element are a kind of powder rate height, washiness, low-gravity a kind of high-adhesiveness breezes of containing, while is the many oarse-grained impurity ores of association also, and this transportation to material in the SINTERING PRODUCTION, mixing, cloth all bring more influence.Therefore, before entering sintering machine proportioning room disk, need the Iron Ore Powder that contains rare earth element is sieved in advance, remove oarse-grained impurity ore with separation, guarantee that normal transhipment, the cloth mixing of transporting in the SINTERING PRODUCTION meet technological requirement.
In the prior art, application publication number is that the Chinese patent of CN 102527630 A has been announced a kind of combined type dregs screening plant (as shown in Figure 1), comprise fixed support 1 ', comb sieve 2 ', netted cylinder 3 ', motor 4 ' and reductor 5 ', cylinder 3 ' be arranged on fixed support 1 ' inboard, soil feed hopper 6 ' end stretch into cylinder 3 ' front end, described cylinder 3 ' front inner diameter is less than back end inside diameter, cylinder 3 ' center be provided with horizontal middle spindle 7 ', cylinder 3 ' inwall be provided with support spoke 8 ', support spoke 8 ' with central shaft 7 ' fixedly connected, central shaft 7 ' an end and reductor 5 ' be connected, motor 4 ' with reductor 5 ' be connected.
Though foregoing invention can be alleviated intergranular adhesive force to a certain extent, reduce the possibility of stifled sieve, but, according to the description in this description of the invention " cylinder 3 ' wall is provided with screen cloth; the big I of sieve aperture is selected screen cloth according to actual needs; generally its slot size is that the screening that 50mm*50mm can satisfy common dregs requires " as can be known, this invention intermediate roll 3 ' in fact only played effect of mesh support screen, cylinder 3 ' can realize effective screening to dregs with " double-decker " of screen cloth, and, the pore size unanimity of screen cloth.Therefore, there is following shortcoming in this invention: (1) material is in screening process, be subjected to the resistance of horizontal and vertical grid lines on the screen cloth simultaneously, the transmitance of material is low, the screening time that needs is just long, for containing the high material of moisture, lump easily, and then be bonded on the screen cloth, cause stifled sieve phenomenon, in addition, the pore size unanimity of screen cloth is namely sieved the pore size unanimity, and little molecule material is very fast to be sifted out, and can't rest in the screening plant for a long time through the material of screen cloth, more increase the weight of the possibility of stifled sieve, also reduced the utilization rate of screen cloth; (2) " double-decker " makes the assembly structure complexity, and, can cause sieving capacity with the overlapping that part of screen cloth of cylinder to reduce being the utilization rate of screen cloth lower, and increase and clean difficulty.In addition, this patent of invention is also pointed out " support spoke 8 ' with central shaft 7 ' fixedly connected ", in conjunction with Fig. 1 can find out cylinder 3 ' on support spoke 8 ' be directly to be fixedly connected on the central shaft, therefore, cylinder 3 ' dismounting is inconvenient, is unfavorable for cylinder 3 ' clean.
