Abstract
The utility model discloses a double-layer round vibration sieve wherein the centrifugal force produced by a core (10) spurring a pair of eccenters (13) fixed in the main axle (12) by a universal coupling (11), which makes a straining box (5) vibrate; in the eccenters is fixed a balancing weight (14) which can adjust the extent of the exciting force by increasing or reducing the balancing weight (14); an upper screen stencil (6) and a lower sieve plate (4) are arranged inside the straining box (5) and finished goods of different norms are available by alternating the aperture of the upper screen stencil (6) and the lower sieve plate (4); the straining box is arranged in the four plastic cement springs (9) and the whole straining box (5) is sealed inside an enclosure (2), on the top of which an inlet scoop is arranged. And thus the exosphere of the bug dust is largely reduced: bulky grains discharge from the discharge hole through a material-drooling plate (3) and the discharge hole is separated by a corniform box (1) into a bulky grains discharge hole, a finished goods grains discharge hole and a powder discharge hole.
Description
Technical field
The utility model relates to a kind of screening machine, particularly relates to a kind of double-deck circular shale shaker.
Background technology
At present, known screening machine all is made up of screen box, sieve plate, motor, eccentric wheel, the sieve plate that becomes angle with level is arranged in the screen box, thereby the driven by motor eccentric wheel rotates and drives the screen box vibration, drop on material on the sieve plate of inclination along with the vibration of sieve plate, tiny material falls from mesh, and thick material then is slipped to the discharging opening discharge of sieve plate end from sieve plate.Contain more tiny dust in the material that this bolting of process goes out, the quality of finished product is descended, especially when chemical fertilizer granules such as urea, carbon ammonia are sieved, seriously influenced the quality of product.
Summary of the invention
The purpose of this utility model provide a kind of can sieve out size specification relatively consistent simple in structure, sieve performance stable, screening efficiency is high and can satisfy the double-deck circular shale shaker of different size screening.
To achieve these goals, the technical solution of the utility model is: design a casing, screen box is installed in the casing, at the screen box internal upper part one upper screen cloth is installed, sieve plate is installed in the bottom, symmetric arrangement diaxon bearing is equipped with self-aligning bearing in the bearing block on screen box, and motor connects by Hooks coupling universal coupling and main shaft, a pair of eccentric wheel is installed on the main shaft, and main shaft passes self-aligning bearing.
As the further technical measures of the utility model, it is to finish by the following technical programs that described screen box is connected with the installation of casing: screen box is installed on four rubber springs, and rubber spring is installed in the spike top, and the spike lower end is fixed on the casing inner wall.
As the utility model technical measures further, the balancing weight of adjusting amplitude is installed, the quantity changeable of balancing weight on the described eccentric wheel.
As the further again technical measures of the utility model, described sieve plate one end is by the leading screw tensioning down, and the other end is compressed by support angle, obtuse angle angle bar, wedge shape batten and tensioning screw.
Owing to adopted technique scheme, the utility model: 1. alleviated greatly and joined the body weight of shaking, and avoided escaping of dust; 2. can select amplitude arbitrarily according to the material characteristic of screening; 3. avoid vibration to pass to motor, strengthened the security of equipment; 4. reduced the infringement that exciting force that screen box resonance produces brings to equipment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
