Abstract
The utility model provides a self-cleaning screen, belonging to the material screening technical field. The utility model mainly solves the problem of screening efficiency of the screen. The technical proposal is that screen bars are a plurality of elastic metal rods arranged in parallelism by prearranged spacing; one end of the elastic metal rod is vertical to and fixed on a beam frame; the other end of the metal rod is in free state; the beam frames are arranged in parallelism according to the arranged beam distances and arranged obliquity; two ends of the beam frame is fixed on a side plate which is connected with a frame of the screen; adjacent screen bars are arranged with difference or different lengths on diameter. The utility model leads a secondary vibration amplitude generated by the adjacent screen bars to be obviously effective; the elastic force can also effectively overcome the resistance of critical grain blocks; the blocked grains are bounded or penetrated, thus improving the screening efficiency and being applied to steel mills, and mine, etc.
Description
Affiliated technical field
The utility model relates to a kind of Cantilevered screen, belongs to the material screening technical field.
Technical background
We know, own to since the material screening, have in arms invariably well sifted this purpose of this sieve is being implemented, is improving, innovated, and updating the material of screen cloth, structure and mesh shape etc., as from the fixing woven screen of mesh, the punching screen cloth is to the broach screen cloth, until to the string screen cloth that can produce secondary resonance at random, the rod screen cloth, Flexible sieve of these classes such as rubber polyurethane or the like all is the achievements that produce for the problem that solves critical particle jam mesh.Facts have proved: fixedly the screen cloth impotentia of mesh solves the blockage problem in the screening process, and is especially even more serious in wet sticking its obstruction of occasion of material.And take a broad view of the producible at work secondary resonance of existing Flexible sieve is to make the jam phenomenon that improvement has been arranged, but its improvement is limited, inadequate, and the phenomenon that critical particle stops up mesh still exists.The compound screen cloth that a kind of fixed, moving grating is formed is disclosed in Chinese patent ZL99221850.0 and ZL99222320.2, it mainly is to utilize fence type elasticity grating producing secondary vibration at random and limiting adjacent one and make the vibrative difference of grating, critical particle is ejected or saturating sieve helping in vibration, stop up mesh certain effect is arranged solving.But, in actual use, material when grating, after the material of especially moving grating, diameter, length are determined, its single quiet rigidity has also just been decided, the elasticity dynamics of its secondary vibration has also just been determined to get off, and when having its elasticity dynamics of secondary vibration of producing during in random vibration when grating less than the resistance of critical particle jam mesh, still can occur stopping up mesh or sticking up excellent phenomenon.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, and provides a kind of screening efficiency high self-cleaning screen cloth.
Technology contents of the present utility model is: this kind self-cleaning screen cloth, its grating are many one end are perpendicular to roof beam structure and be fixed on the roof beam structure by setting the elastic metallic rods that spacing be arranged in parallel that the other end is free state; Roof beam structure is arranged in parallel by the beam distance of setting and the inclination angle of setting, and its two ends are fixed on the side plate; Side plate and vibrating sieving machine body link, and it is characterized in that adjacent grating sets difference or length difference on diameter.
The beneficial effects of the utility model are to utilize the former vibration force of vibratory sieve, strengthen the elasticity dynamics of (or restriction) elasticity grating, so that the amplitude difference significant effective of the secondary vibration that adjacent grating produces, its elasticity dynamics also can overcome the resistance of critical particle jam effectively, make a material of jam or upspring or sieved thoroughly, automatically screen cloth is cleared up, thereby the raising of screening efficiency is broken through.Even to the screening occasion of wet sticking thing, screening effect is also very good.
Description of drawings
Be elaborated below in conjunction with accompanying drawing.
Fig. 1 is the E-E cutaway view of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Among the figure, the 1-roof beam structure, the quiet grating of 2-, 3-moves grating, the 4-side plate.
The specific embodiment
As Fig. 1, Fig. 2.This kind self-cleaning screen cloth, its grating are many one end are perpendicular to roof beam structure 1 and be fixed on the roof beam structure 1 by setting the elastic metallic rods that spacing be arranged in parallel that the other end is free state; Roof beam structure 1 is arranged in parallel by the beam distance of setting and the inclination angle of setting, and its two ends are fixed on the side plate 4; Side plate 4 and vibrating sieving machine body give fastening the connection by the screw of side plate 4 by securing member.The quantity of described grating can decide according to the inboard width of screen cloth, the diameter of grating, the factors such as parallel distance between adjacent grating; The quantity of described roof beam structure 1 can decide according to the length of screen cloth and the factors such as distance between the roof beam structure; The inclination angle of roof beam structure can be according to the character of material, factors such as the size decision of screening amount in the unit interval.After each parameter configures, finish the assembling of this screen cloth on the vibratory sieve body on request, when vibratory sieve after the vibrating motor exciting drives, screen cloth is random vibration also, realizes the screening to material.The characteristics of this self-cleaning screen cloth are: the elastic metallic rod of forming grating there are differences aspect diametrically or the length, and the elastic metallic rod that diameter is little or the length aspect is long is moving grating 3; Otherwise be quiet grating 2.Because present embodiment is provided with the different grating of adjacent diameter first and second row from left to right; third and fourth row is provided with the different grating of length; thereby make screen cloth in random vibration, bring up adjacent grating secondary vibration to have difference; realize the variation of mesh in certain amplitude; obviously play a part attack jam particle with respect to the bigger moving grating 3 of quiet grating 2 Oscillation Amplitudes; make critical particle or upspring or sieved thoroughly, thereby in screening process, improved the efficient of self-cleaning.
Other embodiment of the present utility model also have the different structure of dynamic and static grating employing diameter in same screen cloth; Perhaps dynamic and static grating adopts the different structure of length in same screen cloth; But all moving gratings are identical, and all quiet gratings also are identical.
