Description
Technical field
It is more particularly to a kind of to be applied to moist fine particulate viscous material (outside water the present invention relates to a kind of dry classification sieve
Point content 7~14%, partition size is in 6~13mm) the incorgruous vibration separation screen of dry screening double mass.
Background technology
In the Energy Mix of China, coal accounts for more than the 70% of primary energy, coal as China main energy sources,
Irreplaceable effect is played in the development of the national economy.During 12, five, country continues to press on Washing Steam Coal, particularly brown
The washing upgrading of coal.Because lignite free moisture is higher, and the easy argillization of spoil, coal grain is easy to stick to be clumped together, and common screen(ing) machine is to it
Sieve pore blockade is easily caused during screening, causes screening difficult.For improve screening efficiency, it is necessary to try eliminate coal grain between and coal and sieve
Cohesive force between face, active force of the increase compass screen surface to material.Common screening machine can only be reached by increasing their exciting force
The purpose that coal slime blocks sieve aperture is eliminated, and can so increase the drawbacks of dynamic load of screen(ing) machine is with reduction reliability；Work as exciting force
It is difficult that the particle for making to get lodged in sieve aperture is dished out from sieve aperture again, viscous material is difficult to fully loose and rearranged, and sieves when smaller
Point process substantially deteriorates, and common screening machine can not complete the dry screening to particulate viscous material.
This problem has caused the attention of countries in the world, and conducts extensive research, and occurs in that many new screenings
Machinery, these sieving machines have deficiency；There is clogging in equal thick screen sieve aperture when wet fine is glued in processing；Probability
Classifying screen separation accuracy is low：Piano wire screen silk screen short life；The sieve-plate aperture ratio of flip-flow screening machine is low.Therefore, developing viscous for particulate
The classifying screen of property material is ready to appear.
The content of the invention
The goal of the invention of the present invention is the separation for presence such as classifying screen, piano wire screen sieve, the flip-flow screening machines of prior art
Precision is low, silk screen short life and the low deficiency of sieve-plate aperture ratio provide two vibrations, sieve there is provided one kind by a drive device
The direction of vibration in face on the contrary, and amplitude it is different be applied to moist fine particulate viscous material (free moisture content 7~14%, classification
Granularity is in 6~13mm) dry screening the incorgruous vibration separation screen of double mass.
Realize that above-mentioned purpose uses following technical scheme：
A kind of incorgruous vibration separation screen of double mass, described classifying screen is mainly made up of sieve plate, spring and drive device, its
It is characterised by, the classifying screen is provided with the first plastid and the second plastid, the first plastid is connected by connecting spring and the second plastid
Connect, be connected with drive device；Sieve plate one end is fixed on the first plastid, and the other end is fixed on the second plastid, is formed after fixing
Compass screen surface in same level, the direction of vibration of compass screen surface is on the contrary, and amplitude is different.
Preferably, the first described plastid, the arrangement of the second plastid are divided into arranged in series or are arranged in parallel.
Preferably, the second described plastid is extraneous vibration, and its vibration is to pass through connecting spring by the first plastid
The second plastid is passed to, and the second plastid is opposite with the direction of vibration of the first plastid.
Preferably, described sieve plate uses 65Mn round steel cantilever configurations, is bar screen plate, and sieve plate rod interlocks cloth
Put.
Preferably, described sieve plate is connected in series or in parallel.
Using above-mentioned technical proposal, compared with prior art, the adjacent sieve of the incorgruous vibration separation screen of double mass of the invention
Face makees incorgruous vibration, direction of vibration on the contrary, amplitude is different, and sieve plate carries out secondary flutter simultaneously, and compass screen surface produces very big to material
Active force, effectively eliminate adhesion of the fine moist material to compass screen surface, material loosening is rapid, and this classifying screen uses double mass
Incorgruous vibration plus the secondary vibration principle of elastic rod, screen(ing) machine have disposal ability big, and percent opening is big, and screening efficiency is high, structure letter
The advantages of list, energy-conservation.
