Description

Sieve plate of tension sieve with fiber framework as lining

Technical Field

The utility model belongs to the technical field of mechanical vibration screening, concretely relates to lined fiber skeleton's speed over and open sieve board.

Background

The relaxation sieve utilizes the vibration mechanical principle, the fixed cross beam and the movable cross beam generate mutual motion, the stretched polyurethane sieve surface does relaxation motion, then the sieve surface generates acceleration, the materials are strongly thrown forwards and upwards, in the process of relaxation motion, sieve pores are extruded and stretched to deform, and thus the sieve surface is not stuck with blockage, and the aim of higher sieving efficiency is achieved. Traditional double-deck relaxation sieve is connected through shearing spring and main reel curb plate through two-layer floating frame curb plate from top to bottom, is fixed with elastic polyurethane screen cloth between walking beam and the fixed beam and is the relaxation motion, though can prevent glutinous stifled hole of gluing of wet material, nevertheless meets large granule material sieve life shorter, perhaps then the handling capacity is great, and the bed of material thickness of sifter is great, and material flow speed is slow, and the handling capacity can not satisfy the on-the-spot demand.

In addition, due to the differences in the material contacting the screening surfaces during the screening process, the differences in the velocity and particle size of the material on different screening surfaces, screening decks using the same material can cause localized premature damage or wear.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a lining fiber framework's galloping sieve.

In order to realize the aim, the utility model provides a relaxation sieve plate with a lining fiber framework, which comprises a feeding sieve section, a middle sieve section and a discharging sieve section, wherein the feeding sieve section, the middle sieve section and the discharging sieve section are sequentially connected; aramid fiber reinforced sieve plates are adopted in the feeding sieve sections; the middle screening section adopts a carbon fiber reinforced screen plate; the discharging sieve adopts an ultrahigh molecular weight polyethylene fiber reinforced sieve plate in sections; the feeding screening section, the middle screening section and the discharging screening section are combined and poured in a modular combination mode.

Preferably, the modularization sieve plate mould includes and drives a mould, mould long frame, mould short frame and reinforcing fiber, inserts mould long frame and mould short frame in driving a mould, adopts reinforcing fiber group sieve in the framework between mould long frame and the mould short frame.

Preferably, the lining reinforcement is arranged in both or one of the directions of the screen deck. The lining reinforcing material is arranged in the direction along the short frame of the mold or in the direction along the long frame of the mold. And after the reinforcing material is laid in the screen body, pouring the reinforcing material into the screen plate to be used as a framework.
