Abstract
The utility model discloses a built-in double eccentric weight shafts straight line vibration screen. Compared with an existing vibration screen, the difference is that a vibration generator is arranged in the inner part of a screen box; the screen box takes the straight line vibration through two eccentric weight shafts which take the opposite movement and the vibration force is passed the centroid of the screen box. The utility model has the advantages of simple structure, low centroid of the screen box, balanced rotation, large heavy and straight throwing force and short throwing horizontal distance. Therefore, the screening efficiency is high. The utility model is particularly suitable for the screening of the difficult screening materials.
Description
The utility model relates to a kind of built-in two axis straight line oscillation sieves of laying particular stress on that are used to sieve material, is a kind of moto-vibro screen.
Existing orthoscopic moto-vibro screen, vibrator are weighting block, and vibrator places the outside of screen box.The characteristics of this vibratory sieve are to be easy to levelling, but complex structure, appearance and size is big, and the barycenter height of screen box thereby screen box are easy to generate unsettled top ripple, are unsuitable for for example screening of drilling fluid of difficult screened material.
The purpose of this utility model be the design a kind of be applicable to difficult screened material simple in structure, the screen box barycenter is low, vibrate moto-vibro screen stably.
Scheme of the present utility model is: vibrator is two and acts on the opposite axle of laying particular stress on, lay particular stress on the lower end that axle is positioned at the wire screen of screen box inside for these two, lay particular stress on axle by the bearings on the side plate of screen box both sides for two, the outer flexible company of universal joint of bearing and screen box presses, constitutes a kind of new barycenter simple in structure low, vibrate new-type stably moto-vibro screen.
Vibrator of the present utility model is owing to be two axles of laying particular stress on of making reverse motions, and vibrator is positioned at the inside of screen box.Thereby vibrator when motion exciting force passed through screen box barycenter, to drive screen box be the motion (among Fig. 1 shown in the arrow) of straight line as movement locus.And vibrator reduced by the external barycenter that changes built-in screen box into, making the screen box running steadily, the throwing horizontal range is little, the great efforts of throwing thereby screening efficiency height, is suitable for the screening of difficult screened material.
The utility model is simple in structure, running is steady, be particularly suitable for the screening of difficult screened material in the oil drilling industry.
Description of drawings:
Fig. 1 is that arrow is the straight-line trajectory of screen box shown in schematic diagram of the present utility model, the figure.
Fig. 2 is a transmission diagram of the present utility model.
Opposite two of two direction of motion lay particular stress on axle ［ 1 ］, ［ 1-a ］ place screen box ［ 2 ］ inside wire screen ［ 4 ］ below, during installation two to lay particular stress on axle ［ 1 ］, the normal of ［ 1-a ］ axial connecting line and the angle of horizontal direction be the exciting angle.Laying particular stress on axle ［ 1 ］, ［ 1-a ］ is supported by bearing ［ 12 ］ and ［ 13 ］, ［ 11 ］ and ［ 7 ］ respectively.Two transmissions of laying particular stress on axle are undertaken by tooth axle ［ 10 ］, universal joint ［ 6 ］ flexible connection that bearing ［ 7 ］ and screen box are outer.Bearing ［ 12 ］ and ［ 13 ］, ［ 11 ］ and ［ 7 ］ are installed in respectively on the side plate ［ 8 ］ of screen box both sides.
