Abstract
The utility model provides a self-cleaning sieve, which belongs to the technical field of sieving and classifying materials, and mainly solves the problem of the sieving and classifying efficiency of the sieve. The utility model has the technical proposal that one end of a plurality of sieving strips is vertical to a beam frame to be fixed on the beam frame, while the other ends of the sieving strips are free; the two ends of the beam frame are fixed on a side plate which is connected with a vibrating sieving machine body. The utility model is characterized in that a hammer mechanism which is formed by a connection rod, a heavy block and a reaction seat is arranged below the sieving strips. The reaction seat is fixed on the beam frame or the side plate, the heavy block with certain weight is connected with the connection rod, and the connection rod is movably connected with the beam frame; besides, a set distance is reserved between the upper surface of the heavy block and the lower surface of the sieving strips. The utility model can effectively improve the sieving and classifying efficiency, and is applicable to the steel factories, the mines, etc.
Description
The application for original applying number be 01262004.1 applying date be October 11 calendar year 2001 denomination of invention be dividing an application of self-cleaning screen cloth.
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, to help in vibration critical particle ejected or saturating sieve stops 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, it is characterized in that being arranged with the weight mechanism that forms by connecting rod, pouring weight, counter-force seat at grating, the counter-force seat is fixed on last roof beam structure or the side plate, pouring weight and connecting rod with certain mass link, connecting rod and roof beam structure connect for movable, leave the spacing of setting below the top and grating of pouring weight.
The beneficial effects of the utility model are to utilize the former vibration force of vibratory sieve, under the effect of weight, strengthen the elasticity dynamics of 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.
Figure is a side structure cross-sectional schematic of the present utility model.
Among the figure, 1-roof beam structure, 2-grating, 4-side plate, 7-pouring weight, 8-connecting rod, 9-counter-force seat.
The specific embodiment
As figure, the one end is perpendicular to roof beam structure and be fixed on the roof beam structure 1 by setting the elastic metallic rods that spacing be arranged in parallel for many for this kind self-cleaning screen cloth, its grating 2, and 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 4; Side plate and vibrating sieving machine body give fastening the connection by the screw of side plate by securing member.The quantity of described grating 2 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 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 1 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 the self-cleaning screen cloth of present embodiment are: grating 2 all adopts straight rod; Below grating 2, be provided with the weight mechanism that forms by connecting rod 8, pouring weight 7, counter-force seat 9, the counter-force seat is fixed on last roof beam structure or the side plate, pouring weight 7 with certain mass links with connecting rod 8, and connecting rod connects for activity with roof beam structure 1, leaves the spacing of setting below the top and grating of pouring weight 7.Owing to be provided with weight with certain mass, in random vibration, provide the starting force that makes progress by the machine that shakes through counter-force seat 9, be subjected to downward active force when up again when hitting below the grating, weight obtains up power heavily again when coming downwards to the counter-force seat, and that goes round and begins again impacts below the grating.Connecting rod retrains the pouring weight movement locus and guarantees effective impact point position that gets.Because the secondary vibration of former grating existing certain amplitude in random vibration produces, weight produces impacting of grating in addition is forced to vibration, its result makes the variation aggravation of sieve screen apertures, the elasticity dynamics also is enhanced, thereby the easier sieve of the particle that makes the jam mesh or upspring makes also that wet adhesive material is easier to be shaken off.This effect of self-cleaning is effectively effectively improved screening efficiency.
Weight structural principle in this example is also applicable to various Flexible sieves: as the cleaning to the jam particle of screen clothes such as establishment screen cloth, fence type rod screen cloth, Rubber screen, effect is obvious.
