Description
Affiliated technical field: the utility model belongs to the plant equipment field, is specifically related to a kind of screen cloth of circular shale shaker.
Background technology: in the prior art, the circular shale shaker that is used to screen mineral and other material has models such as 3073 large-scale circular shale shakers, 3373 large-scale circular shale shakers.Above-mentioned large-scale circular shale shaker or the screen cloth that claims to shake large-scale circle sieve go up to adopt generally have two kinds of individual layer screen cloth and double-deck screen clothes, and the sieve aperture shape of individual layer screen cloth is circular hole, and the sieve aperture shape of double-deck screen cloth generally be the upper strata is that circular hole, lower floor are the braiding square hole.Add man-hour, circular hole is rushed out with perforating press, and the braiding square hole is to form with the fine wire braiding.Find that in practice circular hole is easy to stop up for water content height, tough material, the square hole intensity difference of metal wire knitted, service life lack, and the screen cloth that adopts on the above-mentioned large-scale circular shale shaker is generally a whole block material, break a local monoblock screen cloth and all must change very uneconomical practicality.Therefore, the difficult obstruction of research, intensity height, long service life, the novel easily screen cloth of replacing are people's urgent hope.
Summary of the invention: the purpose of this utility model is in order to overcome the defective of prior art, for people provide a kind of difficult obstruction, intensity height, long service life, the replacing screen cloth of novel circular shale shaker easily.
The purpose of this utility model realizes by following technical proposals.
The screen cloth of circular shale shaker of the present utility model is made of the tabular polyurethane screen of two layers of thin up and down that is installed on the circular shale shaker 3, is processed with many sieve apertures on the screen cloth, and the sieve aperture shape of upper strata screen cloth 1 is a rectangle 4, and the sieve aperture shape of lower screen 2 is squares 5.
Each is formed by connecting described two-layer polyurethane screen up and down by a plurality of lamellar screen cloth splicing block 14 amalgamations.
The size range of the rectangle sieve aperture of described upper strata screen cloth 1 is preferably 25～100mm.
The size range of the square sieve aperture of described lower screen 2 is preferably 5～25mm.
The global shape of described upper strata screen cloth 1 is preferably rectangle, is of a size of 3000mm * 7310mm.
The global shape of described lower screen 2 is preferably rectangle, is of a size of 2969mm * 7320mm.
Described polyurethane screen can be the screen cloth that polyurethane or compound polyurethane material are made, also can be other material or other composite make screen cloth.
The shape of the described splicing block of two-layer polyurethane screen up and down and splicing fixed form thereof can design arbitrarily.Two-layer up and down polyurethane screen is installed in the appropriate location of the vibration area of circular shale shaker, and the below of every layer of screen cloth also can be provided with one deck enhancement Layer.
The technical solution of the utility model is that the inventor gropes out by the long-term practice summary, compared with prior art, because the upper strata screen cloth adopts rectangle sieve aperture, lower screen to adopt square sieve aperture, make it overcome the susceptible to plugging weakness of screen cloth in the prior art, and the percent opening of screen cloth increase, production efficiency improves; The screen cloth that adopts polyurethane or compound polyurethane material to make, easy to process, intensity is high, long service life; Two-layer up and down polyurethane screen is spliced by the lamellar screen cloth splicing block of polylith, has broken the splicing block that changes other when a screen cloth splicing block and can also continue to use, and is simple to operation, needn't change whole layer screen cloth, and economical with materials helps producing.
Further describe the utility model below by embodiment, the utility model is not limited only to described embodiment.
