Abstract
The invention discloses a sieve plate. The sieve plate comprises a first filter plate and a second filter plate. The first filter plate is disposed above the second filter plate with a distance between the first filter plate and the second filter plate being 1-2 cm. The right ends of the first and second filter plates are connected through a connecting plate and the left ends of the first and second filter plates are connected through a connecting plate. The first filter plate is provided with first filter holes which are inverted cone type filter holes. The second filter plate is provided with second filter holes which are cone type filter holes. The hole diameter of the upper ends of the second filter holes is smaller than the hole diameter of the lower ends of the first filter holes. The first filter plate removes large particles in coal water slurry and the hole diameter of the upper ends is large, so that large particles are stopped and small particles flows rapidly into the lower second filter plate. The filter holes on the upper end of the second filter plate are small and can further filter the coal water slurry.
Description
Technical field
The present invention relates to a kind of sieve plate, especially a kind of sieve plate for water-coal-slurry vibrating screen.
Background technology
The sieve plate filtering for water-coal-slurry is generally all single layer filter, if mesh is too small, sieve plate easily blocks, and the rate of filtration is slow, if mesh is excessive, the residual particles in water-coal-slurry is often larger, affects water-coal-slurry quality.
Summary of the invention
The present invention relates to a kind of sieve plate, can guarantee the rate of filtration and water-coal-slurry quality.
For realizing this purpose, structure of the present invention is: a kind of sieve plate, comprise the first filter plate and the second filter plate, the first filter plate is arranged on the second filter plate top, the first filter plate and the second filter plate are parallel to each other, the two ends of described two filter plates interconnect by connecting plate respectively, between two filter plates, be spaced apart 1cm～2cm, on described the first filter plate, be evenly placed with the first filter opening, described the first filter opening is the little back taper filter opening in aperture, large lower end, aperture, upper end, on described the second filter plate, be evenly placed with the second filter opening, described the second filter opening is the large taper filter opening in aperture, little lower end, aperture, upper end, the aperture, upper end of described the second filter opening is less than the aperture, lower end of the first filter opening.
Its beneficial effect is: larger particle in the first filter plate elimination water-coal-slurry, because aperture, upper end is larger, can be by larger particle interception, less particle flows into the second filter plate of lower floor fast, the second filter plate upper end filter opening is less, further filtered water coal slurry.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is sectional structure chart of the present invention.
The specific embodiment
Disclosed all features in this description, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this description (comprising any accessory claim, summary and accompanying drawing), unless narration especially all can be replaced by other equivalences or the alternative features with similar object.That is,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
A kind of sieve plate as shown in Figure 1, comprise the first filter plate 2 and the second filter plate 3, the first filter plate 2 and the second filter plate 3 are arranged in parallel, the first filter plate 2 is arranged on the top of the second filter plate 3, the two ends of two filter plates interconnect by contiguous block 1 respectively, between polylith sieve plate by the screen cloth that is composed of a fixed connection of contiguous block 1.Interval 1cm～2cm between the first filter plate 2 and the second filter plate 3, on described the first filter plate 2, be evenly placed with the first filter opening 4, the first filter opening 4 is the little back taper filter opening in aperture, large lower end, aperture, upper end, larger particle can be screened out, on the second filter plate 3, be evenly placed with the second filter opening 5, the second filter opening 5 is the large taper filter opening in aperture, little lower end, aperture, upper end, the aperture, upper end of the second filter opening 5 is less than the aperture, lower end of the first filter opening, the water-coal-slurry being leached by the first filter plate 2 is through the filtration again of the second filter plate 3, particle is stockpiled above the first filter plate 2 and the second filter plate 3, fewer through the water-coal-slurry impurity filtering.
The present invention is not limited to the aforesaid specific embodiment.The present invention expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
