The space-saving circular vibrating screen is mainly technically characterized in that the whole shape of the side surface of a screen box is tapered; the screen surface comprises an upper layer screen plate and a lower layer screen plate which are not arranged in parallel; the material feeding end of the lower layer screen plate is arranged below the material discharging end of the upper layer screen plate; a blind plate for material transition is arranged between the upper layer screen plate and the lower layer screen plate; a vibrator is of single-spindle eccentric type or shaft eccentric type; the supporting point of an anti-vibrating spring is arranged above a horizontal line passing through the gravity center of the screen; the lower part of the anti-vibrating spring is connected with a supporting seat; and the supporting seat is provided with a lateral damper. The space-saving circular vibrating screen can be used for screening in special occasions, has high screening efficiency, occupies small floor area, and can separate three kinds of particle level materials which are not easily mixed, convey materials conveniently, and reduce the investment of auxiliary conveying equipment.

Description

A kind of circular shale shaker of saving the space

Technical field:

The utility model belongs to the vibration screening machinery field, is mainly used in some installing space compactness, realizes that again special sub-material requires occasion and the vibratory sieve of needs, can sieve out three kinds of grade materials, make bunch separately, be difficult for batch mixing, haul is convenient, and the screening efficiency height.

Background technology:

In existing circular shale shaker, realize the screening operation of three kinds of grade materials, mostly be to adopt double-deck circular shale shaker, this sieve upper strata sieve plate and lower floor's sieve plate are arranged in parallel, and adopt an end feed, the form of other end discharge.On screen(ing) machine, have only a feeding end and an exhaust end, three kinds of grade materials that sieve out, a kind of material drops on the below of lower screen, other two kinds of materials can make two kinds of material sub-material difficulties of exhaust end one side, very easy batch mixing like this in exhaust end one side of vibratory sieve, need configuration chute and feed bin separately, floor space strengthens, and also is not easy to clear simultaneously, also needs to increase relevant auxiliary equipment.This in addition traditional double-deck circular shale shaker structure and sieve plate are arranged, can make the sieving area utilization rate of lower floor's sieve plate low, cause bolting efficient low.

The utility model content:

The utility model provides a kind of circular shale shaker of saving the space, can satisfy special occasions installs and the classification needs, can realize from vibratory sieve one end pan feeding, the function of two ends discharge, make the automatic bunch of each grade material, have the batch mixing of being difficult for, take up an area of that the space is little, haul characteristics easily, and because the existence of transition blind plate, the effective sifting area of lower floor's sieve plate is strengthened, and its screening efficiency obviously improves.

The utility model is realized by following measure.A kind of circular shale shaker of saving the space is made up of screen box, vibrator, shock-absorbing spring, bearing and transmission gear for electric motor, it is characterized in that: the side global shape of screen box is tapered, and the big end of taper is recessed to its inside; Compass screen surface in the screen box is made up of upper strata sieve plate and lower floor's sieve plate, and the layout that is not parallel to each other mutually, and the exhaust end a below of upper strata sieve plate is the feeding end of lower floor's sieve plate; Between upper strata sieve plate and lower floor's sieve plate, be furnished with material transition blind plate, the starting point of transition blind plate drops on the feeding end b below of upper strata sieve plate, and the mounted angle of its transition blind plate and length are advisable to the feeding end of lower floor's sieve plate with the material smooth delivery of power that can make the upper strata sieve plate and fall; Vibrator is single shaft piece off-centre or eccentric shaft formula vibrator, and its two ends are installed on the sieve box side plate, and the position is between transition blind plate and lower floor's sieve plate, and the below of screen box center of gravity relatively; The strong point was arranged in the horizontal line top of screen box center of gravity above the shock-absorbing spring, was connected with bearing below the shock-absorbing spring, was provided with lateral damper on bearing.

The vibration damping supported design that the utility model adopts makes screen(ing) machine operate steadily reliably the screen(ing) machine long service life.The utility model also can substitute the classifying screen of other type, by changing the angle between upper strata sieve plate and the lower floor's sieve plate, to adapt to the classification requirement of different material, different process, reduces construction investment.
