Abstract
The utility model relates to a feed buffer device of a vibrating screen. The upper edge of a screen frame of the vibrating screen is welded with an upper horizontal steel pipe, the lower portion of the screen frame of the vibrating screen is welded with a lower horizontal steel pipe, the upper end of a buffer steel plate provided with blanking holes is welded on the upper horizontal steel pipe, and the lower end of the buffer steel plate is welded on the lower steel pipe. A tilt angle between the buffer steel plate provided with the blanking holes and the horizontal plane is alpha, and the distance between the lower edge of the buffer steel plate and screen cloth is more than 50 millimeters. When the vibrating screen operates, materials falling from a feed hopper firstly fall on the buffer steel plate, materials which are smaller than the blanking holes leak from the blanking holes of the buffer steel plate and fall on the screen cloth to be screened, and other materials which are large in size and are in the majority gradually fall onto the lower end portion of the screen cloth from the buffer steel plate to be further screened. Therefore, most of impact force on the screen cloth is born by the buffer steel plate, wherein the impact force is caused by materials falling from the feed hopper onto the vibrating screen, and the intensity of the buffer steel plate is higher than that of the screen cloth. Consequently, the screen cloth is protected, service life of the screen cloth is prolonged, and downtime of the vibrating screen can be greatly shortened.
Description
Technical field
The utility model relates to the charging buffer unit of a kind of screening plant of ore dressing, particularly a kind of vibratory sieve.
Background technology
The charging of existing vibratory sieve is directly to be fallen on the screen cloth by feed hopper because feed hopper is higher apart from screen cloth, therefore when material is fallen on the screen cloth, to the screen cloth effect bigger impulsive force, material is big more, then impulsive force is big more.And screen cloth is generally formed by braided steel wire, receives the impulsive force of material repeatedly, is easy to cause steel wire distortion even fracture, finally makes screen cloth damage, vibratory sieve have to shut down and changes screen cloth.
Summary of the invention
The technical problem that the utility model will solve provides a kind of charging buffer unit that slows down a kind of vibratory sieve of material whereabouts impulsive force.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of charging buffer unit of vibratory sieve comprises the screen cloth on feed hopper that is positioned at the vibratory sieve top and the screen frame that is fixed on vibratory sieve; Horizontal steel tube in the upper limb welding of the vibratory sieve screen frame below the said feed hopper; Horizontal steel tube under the welding of the bottom of vibratory sieve screen frame; The upper end that is provided with the buffering steel plate of material-dropping hole is welded on the horizontal steel tube, and the lower end of buffering steel plate is welded on down on the horizontal steel tube; Being provided with the buffering steel plate of material-dropping hole and the slanted angle of horizontal plane is α, the buffering steel plate lower edge apart from screen cloth greater than 50mm; At first fall on the buffering steel plate from the material that feed hopper falls, wherein the material less than material-dropping hole leaks down from the material-dropping hole that cushions steel plate, drops on the screen cloth and sieves, and remaining material then tumbles the bottom of screen cloth from the buffering steel plate.
The material-dropping hole of said buffering steel plate evenly distributes, and the aperture of material-dropping hole is 15-25mm.
The slanted angle of said buffering steel plate and horizontal plane is α=30 °--45 °.
The beneficial effect of the utility model is: during vibratory sieve work; At first fall on the buffering steel plate from the material that feed hopper falls; Wherein the material less than material-dropping hole leaks down from the material-dropping hole that cushions steel plate; Drop on the screen cloth and sieve, the material that all the other bulks occupy the majority then sieves from the bottom that the buffering steel plate tumbles screen cloth step by step again.The material that drops to vibratory sieve from feed hopper is like this born by the high buffering steel plate of strength ratio screen cloth the impulsive force major part of screen cloth, thereby has protected screen cloth, prolongs the service life of screen cloth, and the downtime of vibratory sieve will greatly reduce.
