The utility model is by using following technical proposals:A kind of polyurethane screen of vibrating screen interlaced arrangement sieve pore,
Polyurethane screen arranges standard aperture sieve pore and smaller aperture due sieve pore on the net, and different pore size sieve pore uses uniform cloth in screen plane
It sets, standard aperture sieve pore and smaller aperture due sieve pore is interspersed or mixed distribution.
Further preferably, same screen plane arrangement smaller aperture due sieve pore, and only smaller aperture due sieve pore in same column in column
Arrangement, the standard aperture sieve pore and smaller aperture due sieve pore interlaced arrangement of adjacent screen mesh plane.
Further preferably, half row smaller aperture due sieve pore of same screen plane interlaced arrangement, it is same to show half row standard aperture
Sieve pore and half row smaller aperture due sieve pore.
Further preferably, same screen plane interlaced arrangement or mixed-arrangement standard aperture sieve pore and smaller aperture due sieve pore,
Wherein there are standard aperture sieve pore and smaller aperture due sieve pore, same row Plays hole and smaller hole interlaced arrangement in same column.
Further preferably, sieve pore interval is thick using larger muscle, and material damage is reduced to enhance screen strength;It is adopted at bolt hole
With larger muscle thickness, material abrasion is reduced with protection vibration screen section.
It is not high that the utility model can effectively solve sieve polyurethane utilization rate, the relatively low problem of screening efficiency.Same sieve is flat
Face sieve pore arrangement is using standard aperture sieve pore and smaller aperture due sieve pore mixed-arrangement or interlaced arrangement;Adjacent screen mesh horizontal screen
Hole arrangement uses standard aperture sieve pore and smaller aperture due sieve pore interlaced arrangement, improves sieve screening efficiency;Sieve use compared with
Big muscle thickness enhances screen strength, is worn by material with reducing vibration screen section, easily maintenance is replaced after screening media.This practicality is new
Type polyurethane mesh structure is simple, economical and practical, and securely and reliably, installation and maintenance are replaced convenient.
