Abstract

The utility model relates to a cantilever assemble cascading screen-net with larger treatment ability in the sieving machine. Aiming at the defects that the vibration sieve net has lower treatment ability, and the vibration sieve net is easy to block at present, the utility model is designed. The whole sieve face is ranged by a plurality of rows of cantilever sieve plates. The sieve plate is composed of a bar of the cantilever and a skeleton with rubber. The sieve plate is arranged on the beam of the sieve box. The utility model has the advantages of large treatment ability, etc. The utility model can be widely used for treating materials, wet materials and difficult sieving materials.

Description

Free cantilever erection cascading screen cloth

The utility model belongs to the free cantilever erection cascading screen cloth of using in the sieving machine with larger process ability.

The screen cloth of using in the existing sieving machine.Normally form by braided steel wire or by the plate punching processing, material moves on screen cloth.Pass the purpose that screen cloth reaches stock grading below falling less than the material of mesh.Because the vibration frequency of vibratory sieve is limited, so the screening efficiency of this screen cloth and disposal ability all are restricted, especially when handling wet, sticking material, stoppage phenomenon very easily.

The utility model is a kind of application cantilever sieve plate assembly unit wire side that designs at the deficiencies in the prior art, and material is the free cantilever erection cascading screen cloth that stairstepping flows on wire side.

The utility model is realized by following measure.Vibrating screen mesh mainly is made of screen box, crossbeam and cantilever sieve plate, and a plurality of cantilever sieve plates of forming compass screen surface are installed on the crossbeam of screen box side by side by screw; The sieve plate plane is horizontal by 10 °-25 ° angle; Whole compass screen surface is the stairstepping arrangement by number row cantilever sieve plate and forms.Each cantilever sieve plate is all formed by calculating bar and skeleton, and an end of grate bar is fixed on the skeleton uniformly, is compounded with rubber, the other end cantilever of grate bar around the skeleton.When vibratory sieve is worked, material on the compass screen surface except the motion mode identical with other screen cloth arranged, the grate bar of cantilever produces secondary vibration by the vibration force of vibratory sieve, simultaneously, between the sieve plate that every row's stairstepping is arranged certain drop is arranged all, so can improve the disposal ability of vibratory sieve greatly.

The utility model has the advantages that, compare that disposal ability increases with the vibratory sieve of same size; When handling wet, sticking material, plug-hole not substantially; Because sieve plate is assembled, so installation and maintenance are more convenient.Be applicable to the classification of various medium and small granularity materials.

Accompanying drawing 1 is a structural representation of the present utility model, and (1) is screen box among the figure; (2) be U-girder; (3) be the cantilever sieve plate; (4) be screw.

Accompanying drawing 2 is the structural representation of cantilever sieve plate (3).(5) are the grate bar among the figure; (7) be rubber.

Accompanying drawing 3 is the A-A cutaway view of accompanying drawing 2, and (5) are the grate bar among the figure; (6) be skeleton; (7) be rubber.

An existing accompanying drawings embodiment of the present utility model.Screen cloth of the present utility model is to be made of screen box (1), U-girder (2) and cantilever sieve plate (3).5 cantilever sieve plates (3) of forming compass screen surface are installed in side by side by screw (4) on the U-girder (2) that connects screen box (1), are about to cantilever sieve plate (3) and drain in the U-lag of U-girder (2), are fixed by screw (4).The plane of every row's cantilever sieve plate is horizontal by 20 ° angle.Whole compass screen surface is stairstepping by 7 row's cantilever sieve plates to be arranged, and the mounted angle of compass screen surface is 35 °, makes the drop that forms about 80mm between every row's sieve plate.The calculation bar (5) of cantilever sieve plate is installed on the metallic framework (6), is compounded with rubber (7) around the skeleton (6).When vibratory sieve is worked, material on the compass screen surface except the motion mode identical with other screen cloth arranged, the calculation bar (5) of cantilever sieve plate (3) produces secondary vibration by the vibration force of vibratory sieve, all have an appointment between the cantilever sieve plate (3) that simultaneously every row's stairstepping the is arranged drop of 80mm is greatly improved the disposal ability of vibratory sieve.

Claims

1, a kind of free cantilever erection cascading screen cloth is made up of screen box (1), crossbeam (2) and cantilever sieve plate (3), it is characterized in that: a plurality of cantilever sieve plates (3) of forming screen cloth are installed on the crossbeam (2) of screen box (1) side by side by screw (4); The sieve plate plane is horizontal by 10 °-25 ° angle; Whole compass screen surface is the stairstepping arrangement by number row cantilever sieve plate and forms.

2, free cantilever erection cascading screen cloth according to claim 1, it is characterized in that: each cantilever sieve plate (1) is all outstanding to be made up of grate bar (5) and skeleton (6), one end of grate bar is fixed on the skeleton uniformly, is compounded with rubber (7), the other end cantilever of grate bar (5) around the skeleton.
