Abstract
In the present invention, a crankshaft-connecting rod mechanism and a swing rod mechanism are used for realizing the swinging movement of great and variable amplitude and lower frequency of a segmented and combined screen surface. The amplitude and the vibration strength of an upper screen surface and a lower screen surface of a screening machine are different. The segmented screen surface is arranged on a rotating shaft at the lower end; the screen surface and a rotating shaft are connected into a whole to simultaneously move by a screen surface fixing device. The segmented screen surface formed by arranging and combining single 60Si2CrVA spring steel wires according to a certain distance and regulation. In the working process of the screening machine, the screen surface vibrates, but the screening box and a machine frame do not vibrate. The screening area is between 12 m<2> and 100 m<2>; the processing capacity of a single screening machine is between 300 T/H and 300 T/H. The screening machine is the biggest screening equipment in the world.
Description
Affiliated technical field
The invention belongs to the screening plant of industries such as coal, metallurgy, building materials, chemical industry, be used for the screening of materials such as coal, mineral.Specifically the present invention is the screening plant that effectively separates according to the granular size difference.
Background technology
Most of screening plant in past all is that compass screen surface vibrates with screen box.As: probability screen, uniform thickness sieve, linear vibrating screen, circular shale shaker etc.For the screening plant of complete machine oscillation, realize that the manufacturing of large-scale sieve has great difficulty, because screen width increases, the strain of Guan Liang increases sharply.Sieving machine need be worked under low-stress state, and need work under high oscillation intensity between compass screen surface and the material.Common screening plant is difficult to satisfy the mechanical requirement of big oscillation intensity.
Summary of the invention
The objective of the invention is to: adopt and improve the sieve oscillation intensity, add the riddle amplitude, satisfy material laws of motion in screening process to greatest extent, obtain the disposal ability of good screening effect and raising screening plant; The present invention also aims to: change the frame for movement of screening machine, adopt the compass screen surface vibration and the non-vibrating motion mode of screen box and frame, the maximization of realization screening plant.
This screening plant is that a kind of compass screen surface vibrates and the non-vibrating large-scale screening plant of screen box and frame.It is characterized by: when compass screen surface of the present invention is worked, compass screen surface produces circular swing motion, compass screen surface is a double-decker, each layer compass screen surface all is to be combined by a plurality of segmented compass screen surfaces, upper strata compass screen surface amplitude is little, and lower floor's compass screen surface amplitude is big, and compass screen surface moves through dynamical system and crankshaft connecting rod system is realized, the rack support screen box, screen box is combined into an organic whole with each mechanism.Compass screen surface by silk screen at a certain distance with regularly arranged, be fixed on the silk screen plate, be equipped with the hole on the silk screen plate, the silk screen two ends are cantilever beam structures, upper strata compass screen surface silk screen diameter is bigger than lower floor's compass screen surface silk screen diameter, silk screen is selected spring steel for use, also can select tool steel for use or according to wear-resisting requirement and alloy treated steel, to improve toughness, impact resistance and the wearability of compass screen surface.Bent axle adopts combination assembling mode, can change the aligning antifriction bearing on the bent axle easily, to the distance proportion adjustment of upper and lower layer compass screen surface apart from the fork oscillation center, can change the size of upper and lower layer compass screen surface amplitude and the size of oscillation intensity.Screen box of the present invention and frame are combined type and install, and can dismantle easily.
The present invention compares with traditional screening plant has following characteristics:
(1) the present invention adopts the compass screen surface vibration, and the non-vibrating motion mode of screen box and frame is in the screening plant course of work, to the dynamic load reduction of factory building and ground.
(2) because the upper strata compass screen surface will expect that the bulky grain among the group sifts out from the upper strata compass screen surface, avoided large granular materials to enter lower floor and impacted screen cloth.
(3) motion mode of compass screen surface of the present invention is movement in a curve, and the movement locus of each point is all inequality on every section compass screen surface.
(4) the present invention adopts the technological parameter of large amplitude, big oscillation intensity and lower frequency, helps expecting group's abundant loose and saturating sieve, and material is the non-blocking screen hole in screening process.
(5) segmented compass screen surface of the present invention is convenient to dismounting, for the replacing and the maintenance at scene provides convenience.
(6) the present invention makes turning cylinder, screen box and frame be in work under the low-stress state because the turning cylinder that the compass screen surface lower end links only produces swing rather than rotation in the course of the work.Solved screening plant maximization problem.
