Abstract
The utility model provides a single vibration source resonance type composite vibrating screen and belongs to the technical field of screening equipment. The single vibration source resonance type composite vibrating screen comprises a screening box and a vibrating motor set. The screening box comprises a screening frame, an operating net and a resonance frame. The screening frame is connected with a fixed machine frame through an elastic supporting device. The vibration motor set is fixed on the upper portion of the screening frame. A distributing machine and a collecting hopper are respectively arranged at two ends of the screening frame. Four sides of the operating net are connected with the screening frame. The resonance frame is placed below the operating net and is parallel to the operating net. The outer side of the resonance frame is connected with resonance springs fixed on the inner side of the screening frame through end shafts. When the screening box is driven by the vibration motor set to perform rectilinear vibration, inertia resonance of the resonance frame is used for knocking the operating net so that unit area processing capacity of the screen and screening efficiency are improved. The single vibration source resonance type composite vibrating screen has the advantages of being simple in structure, high in reliability, high in efficiency, energy-saving and the like.
Description
Technical field
The utility model relates to a kind of with the complex vibration screen(ing) machine of one group of vibrating motor as unique vibration source, belongs to the screening plant technical field.
Background technology
Conventional fine screening, classifying equipoment only have the single vibration form usually, i.e. screen box vibration or screen cloth vibration mode, and its shortcoming is that mass transport is difficult to take into account with saturating sieve ability, screen(ing) machine unit are disposal ability and screening efficiency are difficult to give full play to.In recent years the compound vibrating screen that occurs is when adopting vibrating motor group driving screen box or screen box combination to do straight-line oscillation, other adopts electromagnetic exciter as the second vibration source, drive the vibration transmission system and knock screen cloth, make screen cloth produce complex vibration, although this screen(ing) machine can be taken into account mass transport and saturating sieve ability, but two kinds of vibration sources have reduced the reliability of equipment so that screen(ing) machine structure relative complex, have also increased the energy consumption of vibratory sieve simultaneously.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of simple in structure, reliable operation and the low resonant compound vibrating screen of single vibration source of energy consumption are provided.
Problem described in the utility model realizes with following technical proposals:
The resonant compound vibrating screen of a kind of single vibration source, comprise screen box, vibrating motor group in the formation, described screen box comprises screen frame, working net and resonance frame, described screen frame is connected with fixed frame by resilient supporting unit, its top is the vibrating motor group fixedly, and the screen frame two ends are respectively arranged with distributing device and material collection bucket, is connected with screen frame around the described working net, described resonance frame is positioned at working net below and parallel with working net, and its outside is connected with the resonant spring that is fixed in the screen frame inboard by the end axle.
The resonant compound vibrating screen of above-mentioned single vibration source also comprises a plurality of vibrating heads in the formation, they are distributed on the resonance frame, and the two ends of each vibrating head are affixed with the resonance frame.
The resonant compound vibrating screen of above-mentioned single vibration source also is provided with the holder net between working net and vibrating head, be connected with screen frame around the described holder net.
The resonant compound vibrating screen of above-mentioned single vibration source, described screen box also can be the screen box combinations, and described screen box combination comprises a plurality of screen boxs, and their screen frame is fixed together by screen frame (unit).
The utility model is when utilizing vibrating motor group driving screen box to do straight-line oscillation, also utilize the inertia resonance of resonance frame to knock working net, make working net produce complex vibration, thereby taken into account mass transport and saturating sieve ability, improved screen(ing) machine unit are disposal ability and screening efficiency.Because the utility model only has a vibration source, thus also have simple in structure, reliability is high, the advantage such as energy-efficient.
