Abstract
The invention discloses a bidirectional discharge circular vibrating screen, which consists of a screen body, a vibration generator, springs, a support and a transmission device, and is characterized in that the screen body consists of a screen frame, an upper screen mesh and a lower screen mesh; the upper screen mesh is provided with a discharge opening I, and the lower screen mesh is provided with a discharge opening II; the support is arranged on the lower part of the screen body which is fixedly connected with the support through four groups of springs; and the vibration generator is arranged on the upper part of the gravity center of the screen body. The bidirectional discharge circular vibrating screen has the advantages that the material circular vibrating screen adopts a simple eccentric shaft block to adjust the amplitude, has the characteristics of long slip screen line, multiple screening specifications, quick discharge and high classification efficiency, also has the characteristics of reliable structure, strong excitation force, high screening efficiency, small vibrating noise, firmness and durability, convenient maintenance, safe use and the like, and can be widely applied to classification and separation of materials in the industries such as mining, building material, traffic, energy and the chemical industry.
Description
Technical field
The invention belongs to sieving machine, relate to a kind of being applicable to because of being subjected to the place to limit the occasion of material being carried out gradation sizing, especially a kind of bidirectional discharge circular vibrating screen.
Background technology
Present screening plant, be same direction discharging, when particularly requiring to carry out many gradings, the discharging opening place need occupy bigger area, thereby bring very big difficulty for the conveying discharging of material of different grain size and equipment installation, particularly area, less place, space at the scene are difficult to carry out the arrangement of many sizings equipment.
Summary of the invention
The objective of the invention is in order to solve multi-stage screening narrow and smallly, can't realize the problem of multi-stage screening, and a kind of bidirectional discharge circular vibrating screen is provided because of the applying unit place.This bidirectional discharge circular vibrating screen utilizes the characteristics of place's pan feeding bidirectional discharge, thereby be different from the discharging structure that common circle shakes and sieves, preferably resolve problems such as installation that screening plant brings because of the place is narrow and small, discharge, this equipment has energy consumption low (comparing with linear vibrating screen), efficient height, characteristics that vibratory impulse is little simultaneously.
Technical scheme of the present invention is: a kind of bidirectional discharge circular vibrating screen is made up of sieve nest, vibrator, damping spring group, bearing and transmission device; It is characterized in that: described sieve nest is made up of screen frame and upper and lower layer screen cloth.Be provided with discharging opening I on the net at upper sieve, on lower screen, be provided with discharging opening II, bearing is equipped with in bottom at sieve nest, sieve nest is fixedlyed connected with bearing by four groups of springs, the sieve nest center of gravity on the upper side portion vibrator is installed, vibrator adopts external piece eccentric structure and realizes transmission of power by motor and transmission device, and vibrator can be realized the adjustment of amplitude by adjusting eccentric block.
The invention has the beneficial effects as follows: the material circular impact screen adopts simplified formula eccentric shaft piece to regulate amplitude, and sieve drops down line length, the screening characteristics that specification is many, discharge is fast, classification efficiency is high; Because screen box vibration is strong, reduced the phenomenon that material stops up sieve aperture, make sieve have higher screening efficiency and productivity ratio, simple structure, to change compass screen surface convenient, and it is few to sieve the electric energy that material per ton consumes.And have reliable in structure, exciting force is strong, screening efficiency is high, vibrating noise is little, characteristics such as sturdy and durable, easy to maintenance, safe in utilization, this machine can be widely used in the classification and sorting of the material of industries such as mine, building materials, traffic, the energy, chemical industry.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples;
Fig. 1 is a front view of the present invention;
Fig. 2 is a left view of the present invention.
Among the figure, 1. upper strata screen cloth, 2. discharging opening I, 3. spring, 4. sieve nest, 5. vibrator, 6. lower screen, 7. bearing, 8. discharging opening II, 9. motor.
The specific embodiment
With reference to Fig. 1, Fig. 2, the present invention is made up of sieve nest (4), vibrator (5), spring (3), bearing (7) and transmission device; It is characterized in that: described sieve nest (4) is made up of screen frame and upper strata screen cloth (1), lower screen (6).On upper strata screen cloth (1), be provided with discharging opening I, on lower screen 6, be provided with discharging opening II (8), in the bottom of sieve nest (4) bearing (7) is housed, sieve nest (4) is fixedlyed connected with bearing (7) by four groups of springs (3), sieve nest (4) center of gravity on the upper side portion vibrator (5) is installed, vibrator (5) adopts external piece eccentric structure and realizes transmission of power by motor (9) and transmission device, and vibrator (5) can be realized the adjustment of amplitude by adjusting eccentric block.
The bidirectional discharge circle sieve that shakes is that the inertia force that eccentric block produces when utilizing the inertia machine operation forces screen box to produce vibration, makes the material that is added on the screen(ing) machine compass screen surface produce sling movement, thereby makes the material particles of certain particle size see through sieve aperture, realizes the screening operation.Vibrator is arranged in screen box center of gravity top, and motor drives the vibrator main shaft gyration through V belt, because the centrifugal intertia force effect of uneven weight on the vibrator makes screen box obtain vibration.Change the vibrator eccentric weight, can obtain various amplitude.Screen cloth two ends transverse becomes splayed down, and material feeding end is towards the discharge direction, the material that helps being given on the punch-out equipment scatters rapidly, improve the screening percentage of material, and two-layer up and down screen cloth and two discharging openings up and down, improved the classification efficiency of material again, and circular-arc compass screen surface increases the effective area of screen(ing) machine again, thereby can improve its disposal ability.
