Abstract
The present invention announces a kind of sieve plate with high resiliency compass screen surface and preparation method thereof, belongs to vibrosieve technical field.It includes sieve plate main body and the compass screen surface for being provided with sieve aperture being fixed in sieve plate main body；Compass screen surface makes of elastomeric material；Sieve plate main body and the compass screen surface one moulding by casting after the tensioning independently made.Compass screen surface is fabricated separately with highly elastic material in the present invention, then by high resiliency compass screen surface be tensioned after together with sieve plate main body moulding by casting, the purpose for the arrangement is that making compass screen surface with sieve nest have already been made before integral cast pre-tensioner, still there is very strong elasticity being combined rear compass screen surface with sieve nest.Because high resiliency compass screen surface can increase the vibrating effect of vibratory sieve when being vibrated with sieve, and the deformation of compass screen surface can be bigger, wet glutinous material is set to stick on this compass screen surface, so as to solve the problems, such as wet glutinous material paste compass screen surface, so that persistently keeping high screening efficiency during screening.
Description
Technical field
The present invention relates to vibrosieve technical field, specifically a kind of sieve plate and its making side with high resiliency compass screen surface
Method.
Background technology
One of very intractable material variety for running into, the sieve used currently on the market when wet glutinous material is current screening processing
Plate is mostly that moulding by casting, compass screen surface elasticity will not have very big difference with sieve plate main material elasticity together with sieve plate main body by compass screen surface,
Further, since be once-cast, compass screen surface can be with sieve plate synchronous, therefore compass screen surface does not have good tension effects, wet handling
Serious paste hole problem can be run into during glutinous material, so may result in the very fast reduction of screening efficiency, and clear up compass screen surface extremely
It is difficult, it is often more important that to cause whole screening system or even the working time including crushing system to extend, the serious enterprise that increases uses
The consumption of electricity and equipment and spare part.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of sieve plate with high resiliency compass screen surface and preparation method thereof, can
To solve well at present to the paste hole problem run into during wet glutinous material screening, high screening efficiency can be maintained for a long time, is had
Effect reduces enterprise energy consumption and equipment loss.
The present invention is achieved through the following technical solutions：A kind of sieve plate with high resiliency compass screen surface, including sieve plate main body and solid
The compass screen surface for being provided with sieve aperture being scheduled in sieve plate main body；The compass screen surface makes of elastomeric material；The sieve plate main body makes with independent
Tensioning after the compass screen surface one moulding by casting.
A kind of preparation method of the sieve plate with high resiliency compass screen surface, comprises the following steps, 1. with elastomeric material by compass screen surface system
Discharge；
2. compass screen surface is carried out in the casting mold of sieve plate main body pre-tensioner, sieve plate main body is then poured into a mould.
Compass screen surface is fabricated separately with highly elastic material in the present invention, after being then tensioned high resiliency compass screen surface together with sieve plate main body
Moulding by casting, the purpose for the arrangement is that make compass screen surface with sieve nest have already been made before integral cast it is pre-tensioner, with sieve
Body, which combines rear compass screen surface, still has very strong elasticity.Common sieve plate cast, due in the absence of the pre-tensioned process of compass screen surface, so
The elasticity of compass screen surface can't have obvious strengthen.
The invention has the advantages that with the vibratory sieve of this sieve plate when handling wet glutinous material, due to high resiliency compass screen surface
The vibrating effect of vibratory sieve can be increased when being vibrated with sieve, and the deformation of compass screen surface can be bigger, makes wet glutinous material in this compass screen surface
On can not stick, so as to solve the problems, such as wet glutinous material paste compass screen surface, so that persistently keeping high screening efficiency during screening.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention；
In figure：1st, sieve plate main body, 2, compass screen surface.
Embodiment
As shown in figure 1, a kind of sieve plate with high resiliency compass screen surface, including sieve plate main body 1 and it is fixed in sieve plate main body 1
It is provided with the compass screen surface 2 of sieve aperture；Wherein sieve plate main body 1 and the 2 integral moulding by casting of compass screen surface after the tensioning independently made.Specific processing
Step is：Compass screen surface is first poured into a mould in compass screen surface mould, material selection highly elastic material, is once vulcanized at 100 DEG C -120 DEG C
Carry out, 20 minutes or so rear taking-up compass screen surfaces, be placed in sieve plate casting mold carry out it is pre-tensioner, be compass screen surface produce largely draw
Stretch, then carry out second pouring, material selection high hardness material completes the cast of sieve nest, makes compass screen surface complete to combine with sieve nest, enter
Row post-cure, 100 DEG C -120 DEG C of curing temperature, 40 minutes or so time, finally the sieve plate of completion is finally vulcanized, sulphur
Change 90 DEG C or so of temperature, 12 hours or so time.The sieve plate made by as above flow can make compass screen surface have high elasticity.
It is the sieve plate of common one-time cast-forming below, the data comparison with the present embodiment sieve plate.
| Common sieve plate | Water content（%） | - 5mm weight of material (Kg before sieve） | - 5mm weight of material on sieve（Kg） | - 5mm materials residual rate on sieve（%） |
| Sieve silica perforate 7mm | 1.91 | 0.62 | 32.5 | |
| Sieve Hainan ore deposit perforate 7mm | 0.88 | 0.71 | 80.68 | |
| Sieve Brazilian ore deposit perforate 7mm | 2.0 | 1.7 | 85.00 | |
| Sieve Brazilian ore deposit perforate 7mm | 1.3 | 1.2 | 92.31 |
| The present embodiment sieve plate | Water content（%） | - 5mm weight of material (Kg before sieve） | - 5mm weight of material on sieve（Kg） | - 5mm materials residual rate on sieve（%） |
| Sieve silica perforate 5.5mm | 1.91 | 0.15 | 7.85 | |
| Sieve Hainan ore deposit perforate 5.5mm | 0.88 | 0.05 | 5.68 | |
| Sieve South Africa Iron Ores perforate 5.5mm | 4.9 | 0.1 | 2.04 | |
| Sieve Australia ore deposit perforate 5.5mm | 3 | 0.1 | 3.33 |
" -5mm " refers to that size is less than 5mm in above table, as can be seen that being changed in sieve aperture smaller from above table
In the case of 5.5mm, the residual rate of material substantially reduces, and greatly improves screening efficiency.
