Abstract
The utility model belongs to the material sieving technology apparatus field, particularly a kind of anti-clogging screen cloth, it is characterized in that compass screen surface that is made of the elasticity grating that a row is arranged in parallel and the elasticity grating fixture that equidistantly distributes on this compass screen surface are formed, the elasticity grating can be waveform elasticity grating, form the square sieve aperture of band fillet between the adjacent elasticity grating, also can be vertical bar shaped elasticity grating, adjacent grating and grating fixture form the strip sieve aperture, described grating fixture is a 3-6 root elastic yarn group, doing braiding with the elasticity grating fixes, also can be rubber or elastic polyurethane compressing tablet, the elasticity grating is encapsulated in this elastic pressuring plate, elastic yarn group and elastic pressuring plate can use separately, also can intersect use, and the elasticity grating is a steel wire slat gum bar, or polyurethane strip.This anti-clogging screen cloth prevent the effective of sieve pore blockade, thereby improved screening efficiency.This mesh structure advantages of simple, long service life is applicable to the screening of moist materials such as raw coal.
Description
Technical field
The utility model belongs to the material sieving technology apparatus field, particularly a kind of anti-clogging screen cloth.
Background technology
In the screening of some moist materials, for example in deep screening, tend to take place the sieve pore blockade phenomenon, thereby influence screening effect raw coal.Once developed various vibratory sieves, and attempted to solve blockage problem, but effect is all undesirable.Main cause is that mesh structure is unreasonable.Want thoroughly to solve blockage problem, must fundamentally change the version of screen cloth, the mesh structure that discards tradition.
Summary of the invention
The purpose of this utility model provides a kind of anti-clogging screen cloth of simple and reasonable, vibratory sieve that anti-clogging is effective.
According to anti-clogging screen cloth of the present utility model, it is characterized in that compass screen surface that is made of the elasticity grating that a row is arranged in parallel and the elasticity grating fixture that equidistantly distributes on this compass screen surface are formed.
Described elasticity grating is a waveform elasticity grating, forms the square sieve aperture of band fillet between the adjacent elasticity grating, and perhaps the elasticity grating is a vertical bar shaped elasticity grating, and adjacent grating and grating fixture form the strip sieve aperture.
Described grating fixture is a 3-6 root elastic yarn group, does braiding with the elasticity grating and fixes, and described grating fixture also can be rubber or polyurethane elastic pressuring plate, and the elasticity grating is encapsulated in this elastic pressuring plate.The effect of grating fixture is to make sieve aperture be unlikely to occur bigger distortion in the course of the work.
Described grating fixture on same compass screen surface is elastic yarn group or elastic pressuring plate, perhaps is elastic yarn group and elastic pressuring plate arranged crosswise.
Described elasticity grating is steel wire bar, rubber strip or polyurethane bar.
According to anti-clogging screen cloth of the present utility model, partly form by the non-screening section of band fixture and the screening that only flexible grating constitutes, the screening part is in screening process, under the acting in conjunction of the power of vibratory sieve and the impact that is sized material, the loose effect and the layered effect of moist fine particulate material have been improved, make material obtain the bigger saturating dynamics of squeezing screen, make the sieve aperture can be not blocked, thereby significantly improved the screening effect and the operating efficiency of vibratory sieve.
The grating fixture technology of doing with the elastic yarn group is simpler, but is difficult for compass screen surface is fixed on the framework, adopts the elastic pressuring plate fixture then to be convenient to compass screen surface is fixed on the vibratory sieve framework.It is preferred plan that both combination of advantages are got up.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, anti-clogging screen cloth of the present utility model is characterized in that compass screen surface that is made of the elasticity grating 2 that a row is arranged in parallel and the elasticity grating fixture that equidistantly distributes on this compass screen surface are formed.
As shown in Figure 1, described elasticity grating 2 is a waveform elasticity grating, forms the square sieve aperture of band fillet between the adjacent elasticity grating 2.
Described elasticity grating 2 is a vertical bar shaped elasticity grating, and adjacent grating and grating fixture form the strip sieve aperture.
Shown in Fig. 1 both sides, described grating fixture is a 3-6 root elastic yarn group 1, does braiding with elasticity grating 2 and fixes.
Or shown in the part of Fig. 1 middle part, described grating fixture is rubber or polyurethane elastic pressuring plate 3, and elasticity grating 2 is encapsulated in this elastic pressuring plate 3.
Grating fixture on same compass screen surface is elastic yarn group 1 or elastic pressuring plate 3, perhaps is elastic yarn group 1 and elastic pressuring plate 3 arranged crosswise.Scheme shown in the figure is the version of arranged crosswise.
In concrete enforcement, the elasticity grating is steel wire bar, rubber strip or polyurethane bar, also can adopt the elasticity grating of other materials.
Anti-clogging screen cloth of the present utility model, anti-sieve pore blockade is effective, the screening efficiency height, screening effect is good.Be applicable to the screening of moist materials such as raw coal.
