Abstract

The utility model discloses a screening device suitable for screening of various sheeted and granular material, and relates to novel screening equipment used for screening light non-metal materials, in particular to a plane circular vibrating screen. In the utility modle, the upper part of a support (1) is connected with two cross beams (2), four hanging steel wire ropes (3) are arranged at the four corners of the two cross beams (2), a screen box (20) is hanged below the lower side, a discharge hatch opening (4) is connected to the lower end of the dip angle of a first layer screen plate (16) on the left side of the screen box (20), a feeding hole (21) is formed at the upper right end of the screen box (20), a discharge hole (19) is formed at the bottom left end of the screen box (20), and the vibrating mechanism is arranged in the middle part of the screen box (20). In the utility model, due to the adoption of round plane motion principle, through which a vertical central shaft combined with an eccentric block is adopted as the core, exciting force is produced on a plurality of plane surfaces, and material do jumping exercise thereby; a special grease lubricating system is adopted, and the plane circular vibrating screen is kept in the excellent lubrication state; the four corners are hanged through the four steel wire ropes, a damping device is not required, and stress deformation and fatigue load can not be produced; and compared with similar vibrating screens, the utility model has the advantages of long service life, low failure rate and high production and screening efficiencies.

Description

A kind of flat circle vibratory sieve

Technical field: the utility model relates to a kind of screening that is fit to multiple sheet, powder and granule shape material, a kind of flat circle vibratory sieve of novel screening plant that uses when screening in particular for the lightweight non-metallic material.

Background technology: all kinds of vibrosieve equipment of applying at present, its vibration mode, generally be divided into three kinds of forms of motion such as straight-line oscillation, circular vibration, elliptical vibration, the screening plant of above-mentioned three kinds of vibration modes is used for the heavier material screenings of industry proportion such as metallurgy, mine, coal, building materials more.But be difficult to be applicable to the screening of lightweight non-metallic material.

The utility model content: the purpose of this utility model is a kind of flat circle vibratory sieve of novel device that uses when having designed the screening of screening lightweight non-metallic material.The technical solution adopted in the utility model is: described support 1 top connects two crossbeams 2, hang steel wire rope 3 four of two crossbeams, 2 four angle apparatus, downside is hung screen box 20, discharge Hatch Opening 4 is connected lower end, ground floor sieve plate 16 inclination angle, screen box 20 left side, charging aperture 21 devices are at screen box 20 upper right sides, discharging opening 19 devices are at screen box 20 lower-left ends, and the vibrating mechanism device is at screen box 20 middle parts.

The beneficial effects of the utility model are: 1, add the disk motion principle that eccentric block is a core owing to having utilized with vertical center axis, design sieve plate and central shaft have an inclination angle, produce the exciting force on a plurality of planes, make material produce jumping; Four jiaos with four wire rope hangings, no vibration absorber, do flexible circular motion in the course of the work, other parts of getting along well collide, do not produce stress deformation and fatigue load, have longer than the similar vibratory sieve life-span, fault rate is low, use, big, the screening efficiency advantages of higher of easy to maintenance, production capacity.

2, two of this mechanism groups of six roots of sensation triangle rubber strips are passed to vertical center axis lower end belt pulley with power through motor, drive the central shaft rotation, and two eccentric blocks produce centrifugal exciting force about making, and force whole screen box to do the flat circle motion.Eccentric block is the exciting source that produces this device up and down, and two same phase angles of eccentric block produce two vector additions, and whole screen box is formed a vector and (total exciting force).

3, the metal (upper grease lubricating system of this mechanism is one of special construction of this device.Its advantage is that an oil filler is arranged at top, and lubricating grease adds upper bearing (metal), after date in the time of a section, and grease is thinning to flow into lower bearing room by oil pipe, and same lower bearing room also is provided with an oil filler, and two bearings chamber thin oil flows out by oil-out.Make lubricating system form a unimpeded system of turnover.
