Abstract
The utility model provides a composite sieve plate with a replaceable cantilever, which is composed of a basal plate 1, a pipe-shaped cross beam 2 with a row of side holes, a set of composite sieve plate strips 3 inserted in the side holes of the pipe-shaped cross beam 2, and fixing screws 4, wherein, each composite sieve plate strip is composed of a long and narrow U-shaped rigid skeleton 3-1 with an angle head and a non-metal wearable outer sleeve 3-2 sheathed on the skeleton 3-1. The composite sieve plate strip has rigidity as well as wear resistance, so the service life can be improved. With the adoption of the cantilever type structure, the secondary vibration can be generated in the process of operation, and the sieving efficiency can be improved thereby; with the adoption of the inserting structure, the damaged sieve plate strips are easy to replace, and the labor productivity can be improved thereby. The composite sieve plate with a replaceable cantilever can be widely used for the sieving of the metallurgy industry, the chemical industry, the mine industry, the coal industry, etc.
Description
Technical field
The utility model belongs to the screening plant field, and the replaceable compound sieve plate of particularly a kind of cantilevered is applicable to the stock grading in the industry such as metallurgy, chemical industry, mine, coal.
Background technology
The screening plant that present employed stock grading is used mostly is vibratory sieve, and used screen cloth has mesh grid, rubber net and polyurethane net etc.Mesh grid generally is woven into straight carbon steel and spring steel wire, the wearing and tearing of this Netease, and service life is short, frequently change, and has reduced utilization rate of equipment and installations, and labour intensity is big.Rubber and polyurethane screen are wear-resistant, and long service life, shortcoming are that percent opening is low, easy plug-hole, and sieve output is lower.
Summary of the invention
The purpose of this utility model provides a kind of replaceable compound sieve plate of being made up of base plate, tubular crossbeam and composite screen lath of cantilevered, when significantly improving screening precision and efficient, prolong the service life of sieve plate, be easy to change impaired grating in the use, improved utilization rate of equipment and installations, reduced labor intensity.
According to the replaceable compound sieve plate of cantilevered of the present utility model, it is characterized in that on the base plate of sieve, being provided with 2～3 tubular crossbeams, the side of every tubular crossbeam is provided with one group of evenly distributed hole, the elbow of one group of composite screen lath inserts in the tubular crossbeam hole, composite screen lath and tubular crossbeam are interfixed and form cantilever support with fixed screw, the length of the bracketed part of composite screen lath equals two distances between the tubular crossbeam.
According to the replaceable compound sieve plate of cantilevered of the present utility model, described composite screen lath is the long and narrow U-shaped spare of band elbow, is made up of the long and narrow U-shaped rigid backbone of band elbow and the nonmetal wear-resisting overcoat that is enclosed within on this rigid backbone.
According to the replaceable compound sieve plate of cantilevered of the present utility model, described wear-resisting nonmetal overcoat is the holohedral symmetry step, is forming 2-4 trapezoidal sieve within the composite screen lath and between each sieve plate bar.
According to the replaceable compound sieve plate of cantilevered of the present utility model, described composite screen lath is made up of long and narrow U-shaped spring steel rigid backbone and the wear-resisting overcoat of polyurethane that is enclosed within on this spring steel rigid backbone.
Adopt compound sieve plate of the present utility model, combine resistant polyurethane wearing and tearing, therefore spring steel intensity height, resilient advantage have wear-resistantly, and the life-span is long, the characteristics that percent opening is high.Owing to adopted cantilever design, cantilever produces secondary vibration in screening process, has greatly improved screening efficiency simultaneously, and comparable General Purpose Rubber of output or polyurethane net improve 1.5-2 doubly, and the raw meal particle size that is sieved out simultaneously is even.
