Preferably, the braiding point of the broadwise grating of said upper strata screen cloth and warp-wise grating is positioned at the said top of sieve aperture down, and the braiding point of the broadwise grating of said lower screen and warp-wise grating is positioned at said below of going up sieve aperture.

Further; The said sieve aperture of going up is cut apart four effective sieve apertures of going up of formation by the broadwise grating of lower screen and warp-wise grating; Said down sieve aperture is cut apart by the broadwise grating of upper strata screen cloth and warp-wise grating and is formed four sieve apertures effectively down, said effectively go up sieve aperture with effective under sieve aperture big or small identical.

Further, said upward sieve aperture is square sieve aperture with following sieve aperture, and the said sieve aperture of effectively going up is square sieve aperture with effective sieve aperture down.

Preferably, said upper strata screen cloth and lower screen be the plain weave type screen cloth for being formed by straight shape broadwise grating and the interlaced braiding of straight shape warp-wise grating all, and said broadwise grating and warp-wise grating are the metal grating.

The anti-blocking hole sizer net of the double-layer composite of the utility model; Utilize two layers of relative slight vibration of screen cloth, help the critical point granule materials and sieve, effectively solve the problem of screen cloth plug-hole; And can adopt the collocation of scalping bar and little sieve aperture, improve the rub proofness and the service life of screen cloth.

Description of drawings

Fig. 1 is the anti-blocking hole sizer web frame of the double-layer composite of a utility model sketch map.

The specific embodiment

Further specify below in conjunction with the scheme of accompanying drawing the utility model.

As shown in Figure 1; The anti-blocking hole sizer net of the utility model double-layer composite comprises the upper strata screen cloth, glued or be fixed on upper sieve side's off the net lower screen with metal solder through elastic caoutchouc, and upper strata screen cloth and lower screen are by broadwise grating and the interlaced braiding formation of warp-wise grating; Form the identical last sieve aperture 1 of size between broadwise grating that the upper strata screen cloth is adjacent and the warp-wise grating; Form the identical following sieve aperture 2 of size between broadwise grating that lower screen is adjacent and the warp-wise grating, last sieve aperture 1 evenly is overlapping with following sieve aperture 2, and last sieve aperture 1 is identical with following sieve aperture 2 sizes; Be square sieve aperture, the length of side is W.The broadwise grating of upper strata screen cloth and the braiding point 3 of warp-wise grating are positioned at the top of sieve aperture 2 down, and the broadwise grating of lower screen and the braiding point 4 of warp-wise grating are positioned at the below of sieve aperture 1.Wherein, last sieve aperture 1 is cut apart by the broadwise grating of lower screen and warp-wise grating and is formed four and effectively go up sieve apertures 11, following sieve aperture 2 by the broadwise grating of upper strata screen cloth and warp-wise grating cut apart form four effectively under sieve apertures 21; Effectively go up the big or small identical of sieve aperture 11 and sieve aperture 21 effectively down, effectively go up sieve aperture 11 and effective under sieve aperture 21 be square sieve aperture, the length of side is L; If the upper strata screen cloth is identical with grating diameter in the lower screen, be made as Φ, be prone to knowledge by Fig. 1; W=2*L+ Φ; The sieve aperture length of side W that is every layer of screen cloth is more than the twice of effective sieve aperture length of side L, can solve scalping bar and the little sieve aperture unmanageable technological problems of arranging in pairs or groups, thereby can use the collocation of scalping bar and little sieve aperture; And the overstriking of grating diameter, the wearability and the service life of having improved screen cloth.

Upper strata screen cloth and lower screen be the plain weave type screen cloth for being formed by straight shape broadwise grating and the interlaced braiding of straight shape warp-wise grating all; Broadwise grating and warp-wise grating are the metal grating; Metal grating diameter of phi is greater than the common Weaving type screen cloth of same specification, to improve screen cloth wearability and screening efficiency.

Among Fig. 1, every layer of screen cloth warp-wise and broadwise grating will evenly be divided into sphere of movements for the elephants to rectangular mesh each other and form effective sieve aperture, and this screen cloth is when screening, and two layers of relative slight vibration of screen cloth help the critical point granule materials and sieve, and effectively solve the problem of screen cloth plug-hole.

The anti-blocking hole sizer net of the double-layer composite of the utility model; With the two dimension on plane fixedly sieve aperture expand to the changed sieve aperture of stereoscopic three-dimensional, promptly in the random vibration of screening process, the slight secondary vibration that utilizes two-layer screen cloth to produce to each other; Realized the continuous variation of sieve aperture in screening; Just do not have fixing critical particle material relatively yet, make jam material betwixt upspring or sieve, effectively solve the problem of screen cloth plug-hole.Because upper and lower two-layer screen mesh is more than the twice of effective sieve aperture, correspondingly, the diameter of metal grating also can correspondingly increase, thereby has solved the process issues of scalping bar and the collocation of little sieve aperture, the rub proofness and the service life of having improved screen cloth.

According to material characteristics; Can do corresponding adjustment to the size of metal grating diameter of phi; Make it have rational elasticity dynamics and Oscillation Amplitude, make screen cloth be in best screening state, screening efficiency can improve about about 28% than common screen cloth; Realize the self-cleaning function of screen cloth, significantly reduced the obstruction of sieve aperture.The anti-blocking hole sizer net of the double-layer composite of the utility model mainly screens large granule shape material or extra granular shape material.

More than just the utility model has been carried out exemplary explanation, the concrete implementation of the utility model is not limited thereto.The insubstantial modifications that design of any employing the utility model and technical scheme are carried out is all within the protection domain of the utility model.
