Abstract
The utility model relates to a constant thickness screen, in particular to a feeding device of the constant thickness screen. The utility model solves the problems that the constant thickness screen is high in feeding speed and large in impact force, thereby leading to high loss rate of carbon blocks and low screening efficiency, and the screen is extremely and easily damaged. The feeding device of the constant thickness screen comprises a positive feeding chute and a reverse feeding chute, which are positioned above the constant thickness screen respectively, wherein an arc-shaped groove is fixed at a discharge opening of the positive feeding chute; and a radial slit is formed in the arc-shaped groove. The feeding device of the constant thickness screen has a simple structure, is firm and durable, economical and practical, solves the problems of high loss rate of carbon blocks, extremely and easily damaged screen and low screening efficiency due to high feeding speed and large impact force in the conventional constant thickness screen, and can be widely suitable for coal mine enterprises.
Description
Technical field
The utility model relates to the uniform thickness sieve apparatus, is specially a kind of uniform thickness and is sieved into materials device.
Background technology
Uniform thickness sieve is to have box vibrator and several sections to be the linear vibrating screen that broken line type does not wait the gradient compass screen surface.The pan feeding of uniform thickness sieve is main pan feeding from the positive and negative pan feeding chute, particularly forward pan feeding chute that are positioned at uniform thickness sieve top, reaches 48 ° and do not have surge bunker and charging gear because of the pan feeding discrepancy in elevation reaches 8m, the chute gradient, so pan feeding speed is fast, impulsive force is big.When the charcoal piece passed through feed box, the strike plate collision that is provided with in the collision of the collision when the charcoal piece of forward and reverse pan feeding chute compiles, charcoal piece and box body wall, particularly charcoal piece and the feed box and the collision of charcoal piece and uniform thickness sieve plate caused the carbon block smashing especially severe; Secondly because main pan feeding direction is consistent with compass screen surface material movement direction, under above-mentioned big impulse force, make material have little time first knick point that sieve just has been flushed to the uniform thickness sieve, cause the effective sifting area of sieve not make full use of, disposal ability is limited, and screening efficiency is low; Last uniform thickness sieve upper strata screen cloth particularly the screen cloth of first section gradient (account for entire area 1/3) because of bearing the damaging impact of pan feeding; be damaged very soon; it is frequent to cause screen cloth to change; and sieve breakage need be forced to when serious shut down and handles; directly restricted production, and maintenance workload is big, maintenance cost is high.
Summary of the invention
The utility model has proposed a kind of uniform thickness and has been sieved into materials device in order to solve the problem that existing uniform thickness sieve is fast because of pan feeding speed, impulsive force causes charcoal piece loss late height greatly, screen cloth very easily damages, screen rate is low.
The utility model is that the following technical scheme of employing realizes: a kind of uniform thickness is sieved into materials device and comprises forward pan feeding chute and the reverse pan feeding chute that is positioned at uniform thickness sieve top, and the discharging opening place of forward pan feeding chute is fixed with deep-slotted chip breaker.
When material falls when forward pan feeding chute passes through deep-slotted chip breaker, the direction of motion of material is changed gradually by segmental arc and is produced resistance, thereby force material to slow down, extenuate impulsive force, covering the capable section brief acceleration of arc when material also eliminates substantially, import the material in the reverse pan feeding chute simultaneously, deliver to the screening origin or beginning of uniform thickness sieve together and sieve.The structure of described uniform thickness sieve is as well known to those skilled in the art.
Further, be provided with in the groove of described deep-slotted chip breaker and be actinoid seam; The arc length of deep-slotted chip breaker is that 2.5m, radius of curvature are 2.4m, like this material by the time can not stop up and can spread out with the guide rail effect of bar seam, whole breadth of size distribution by the uniform thickness sieve falls, and has guaranteed the uniformity and the shatter value of pan feeding, and screening efficiency is greatly improved.
The utility model has following beneficial effect:
1, by to the deceleration of whereabouts material, reduce impact energy, thoroughly changed the collision of bump, charcoal piece and equipment etc. mutually under big impulse force of original charcoal piece, significantly reduced the loss of charcoal piece, charcoal piece loss late has reduced more than 3 percentage points, can increase charcoal piece 5 over thousands of tons in 1 year, press 250 yuan of calculating of smalls and charcoal piece price difference per ton, surplus direct economic benefit reaches 100 ten thousand yuan.
2, have the service life of screen cloth and original have only 15 days and extend to more than 180 days, thoroughly changed simultaneously and improved production capacity originally, significantly reduced the maintenance and the accessory consumption of sieve because of frequently repairing, repair welding and replacing screen cloth influence the phenomenon of production.Can save 20,000 yuan of screen cloth fittings costs every year, 1.5 ten thousand yuan of manual maintenance expenses.
3, because the seam of the bar in the deep-slotted chip breaker is radiation shape, material by the time can not stop up and can spread out with the guide rail effect of bar seam, whole breadth of size distribution by the uniform thickness sieve falls, the uniformity and the shatter value of pan feeding have been guaranteed, screening efficiency is greatly improved, and per hour treating capacity has original 200 tons to increase to 350 tons.
The utility model is simple in structure, sturdy and durable, economical and practical, has solved the problem that existing uniform thickness sieve is fast because of pan feeding speed, impulsive force causes charcoal piece loss late height greatly, screen cloth very easily damages, screen rate is low, can be widely used in coal mining enterprise.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-uniform thickness sieve; 2-forward pan feeding chute; The reverse pan feeding chute of 3-; The 4-deep-slotted chip breaker.
The specific embodiment
A kind of uniform thickness is sieved into materials device, comprises being positioned at forward pan feeding chute 2 and the reverse pan feeding chute 3 that uniform thickness sieves 1 top, and the discharging opening of forward pan feeding chute 2 is fixed with deep-slotted chip breaker 4.Be provided with in the groove of described deep-slotted chip breaker 4 and be actinoid seam.The arc length of described deep-slotted chip breaker 4 is that 2.5m, radius of curvature are 2.4m.
