Abstract

The invention discloses a single-shaft elliptic vibration sieve. The single-shaft elliptic vibration sieve comprises a single-shaft round vibration sieve, wherein a sieve plate is mounted in the single-shaft round vibration sieve; secondary elliptic vibration springs are symmetrically and uniformly distributed between a supporting seat of the sieve plate and a sieve body; a coupling is mounted outside the sieve body at one end of a vibration shaft of an adjustable eccentric block mounted in the sieve body; a motor is connected onto an outer-end shaft of the coupling; bases are arranged under the motor and the sieve body respectively; a primary spring is mounted between the base of the sieve body and the sieve body in a balanced way; the sieve plate is a ladder-shaped bar sieve plate; and the coupling is a quincuncial coupling. According to the single-shaft elliptic vibration sieve, the sieve body is driven to work by using a set of single-shaft vibrators, and the vibration track of the sieve plate is changed into an elliptic shape through the secondary springs at the same time, so that the vibration amplitude is increased by 2-3 times, the phenomenon of hole blockage is prevented, and the sieving efficiency is improved.

Description

A kind of single shaft elliptically vibrating screen

Technical field:

The present invention relates to screening plant, particularly a kind of single shaft elliptically vibrating screen that passes the raising screening efficiency of shaking by spring secondary.

Background technology:

Existing elliptically vibrating screen all is take three axles or diaxon vibrator as the work of vibratory drive sieve nest, has complex structure, and weight is large, energy consumption is high, the shortcoming of inconvenient maintenance.

Summary of the invention:

The purpose of this invention is to provide single shaft elliptically vibrating screen a kind of simple in structure, lightweight, that energy consumption is low, easy to maintenance.

Technical scheme of the present invention is finished as follows, a kind of single shaft elliptically vibrating screen, it includes a single shaft circular shale shaker, it is characterized in that: a sieve plate is installed in single shaft circular shale shaker sieve nest, symmetry is evenly equipped with the secondary elliptical vibrating spring between the supporting seat of sieve plate and sieve nest, one end of the adjustable eccentric piece vibrating shaft of installing in sieve nest is equipped with shaft coupling outside sieve nest, be connected with a motor at the outer end of shaft coupling axle, be respectively equipped with base below motor and sieve nest, balance is equipped with spring one time between sieve nest base and sieve nest.Sieve plate is a kind of stairstepping bar screen plate.Shaft coupling is a kind of quincunx shaft coupling

The present invention drives sieve nest work with one group of single shaft vibrator, and makes the sieve plate oscillation trajectory become ellipse by the secondary spring simultaneously, makes amplitude increase 2-3 doubly, has not only prevented plug-hole, and has improved screening efficiency.

Description of drawings:

Fig. 1 is structural representation of the present invention.

The specific embodiment:

Describe by reference to the accompanying drawings embodiment in detail, it comprises a single shaft elliptically vibrating screen, its improvements are that the bar screen plate 1 that a stairstepping is arranged is installed in a single shaft circular shale shaker sieve nest 3, the symmetrical uniform secondary elliptical vibrating spring 2 that is equipped with between the supporting seat of bar screen plate and sieve nest, one end of the adjustable eccentric piece vibrating shaft 6 of installing in sieve nest is equipped with a quincunx shaft coupling 7 outside sieve nest, be connected with a motor 5 at the outer end of plum coupling axle, be respectively equipped with base below motor and sieve nest, balance is equipped with spring 4 one time between sieve nest base 8 and sieve nest.The present invention adopts one group of single shaft vibrator to make sieve nest that the vibration of circle track occur, and makes the vibration of sieve nest generation elliptical orbit by the secondary elliptical vibrating spring again.In secondary vibration, make the amplitude of sieve plate increase 2-3 doubly, greatly reduced the plug-hole phenomenon, improved screening efficiency.
