Description
Technical field
The present invention relates to a kind of vibratory sieve that is applicable to metallurgy industry sintering deposit, pellet and the screening of all kinds of lump material grade.
Background technology
In sintering deposit, the pellet screening check, a general sample needs the data detection report of six grades, need sieve out earlier greater than 40mm with less than the grade of 5mm, rescreens and tells the following grade of 40-25mm, 25-16mm, 16-10mm and 10mm.40-25mm, 25-16mm, 16-10mm grade are made drum test, and other grade is only made proportion grading.So that its check meets sintering deposit, pellet screening test stone GB8209-1987.
The vibratory sieve that is used for above-mentioned test at present has following two kinds of forms:
First kind: the entire combination structure
1, sieve nest be designed to two the screening directions be integrated.
2, can't solve in the screening process, the cancelling out each other of positive and negative both direction active force, so in use compass screen surface gets stuck serious screening once, sieve cover cleaning once, screening check accuracy can't be up to state standards.
3, because of sieve nest is an overall structure, so the big vibrator that uses of sieve nest volume must strengthen, so just caused the noise of equipment big, no locking device dust pollution is serious, and it is healthy to have a strong impact on operating personnel.
Second kind: secondary or three grades of sieves
A general sample needs the data detection report of six grades, needs two covers just can finish so do check with this sieve that shakes.
Therefore the equipment feature of environmental protection is poor, and labour intensity is big, and occupation area of equipment is big, and the screening time is long, owing to be that the two covers sieve that shakes is finished the screening check, can cause the material deficient phenomena when material shifts, and it is inaccurate to make assay.
Summary of the invention
The problem to be solved in the present invention is: a kind of six grades and high mining check vibratory sieve of screening accuracy of once can sieving out is provided.
For addressing the above problem, the present invention includes frame and secondary linear vibrating screen and three grades of linear vibrating screens of being connected with frame by flexible support members separately respectively, secondary linear vibrating screen and three grades of linear vibrating screens are provided with vibrator separately, the oversize discharging opening of the upper strata screen cloth of secondary linear vibrating screen, the screenings discharging opening of the lower screen of secondary linear vibrating screen and all discharging openings of three grades of linear vibrating screens respectively are provided with a magazine, the oversize discharging opening of the lower screen of secondary linear vibrating screen and the feeding inlet of three grades of linear vibrating screens, three layers of mesh size of three grades of linear vibrating screens are between the upper sieve screen distance and lower screen aperture of secondary linear vibrating screen.
In order to make its check can meet sintering deposit, pellet screening test stone GB8209-1987, the upper sieve screen distance of described secondary linear vibrating screen is that 40mm, lower screen aperture are 5mm, and the upper sieve screen distance of three grades of linear vibrating screens is that 25mm, middle level mesh size are that 16mm mm, lower screen aperture are 10mm.
In order to make its compact conformation, the screen cloth of described secondary linear vibrating screen and three grades of linear vibrating screens is obliquely installed, three grades of linear vibrating screens be positioned at the secondary linear vibrating screen under, the screen cloth of secondary linear vibrating screen is downward-sloping to the right side of frame from the left side of frame, and the screen cloth of three grades of linear vibrating screens is downward-sloping to the left side of frame from the right side of frame.
In order to make it simple in structure, described frame comprises base and four columns that are fixed on the base, the secondary linear vibrating screen is arranged on the top of four columns by four flexible members that are connected with four columns respectively, three grades of linear vibrating screens are arranged between four columns by four flexible members that are connected with four columns respectively, the oversize discharging opening of the lower screen of secondary linear vibrating screen be positioned at three grades of linear vibrating screens charging aperture directly over, the oversize discharging opening of the lower screen of secondary linear vibrating screen is connected by elephant trunk with the charging aperture of three grades of linear vibrating screens.
In order to reduce noise that the present invention in use occurs and dust to the pollution of environment with to the injury of human body, the present invention includes seal bootr, all parts except that seal bootr of mining check vibratory sieve all are in the seal bootr.
In order to reduce vibrations, described flexible member comprises spring, upper support arm and lower support arm, and is at regular intervals between upper support arm and the lower support arm, and spring connects upper support arm and lower support arm.
Beneficial effect of the present invention: the present invention sieves out earlier bigger grade and less grade by a secondary linear vibrating screen, and then four grades in the middle of telling by three grades of straight level vibratory sieves, two linear vibrating screens can be worked simultaneously and be noiseless each other, not only difficult generation compass screen surface gets stuck but also is difficult for taking place material loss, screening accuracy height.
