Description
Technical field
A kind of flip flop screen being transformed into by single-deck vibrating screen is the utility model is related to, belongs to machine-building and mineral machining object
Expect the technical field of classification.
Background technology
Under the background that national requirements related industry reduces that production cost is increased economic efficiency, to inefficient using highly energy-consuming
Equipment upgraded or be replaced by more excellent equipment, the steel of highly energy-consuming, building materials, coal, mineral processing and other fields
Enterprise higher economic benefit room for promotion be present, promote to carry out fine particle stage material (3-13mm) and moist material (3 to mineral
~30% moisture) screening propose an urgent demand, common vibratory sieve, high-amplitude screen, angle sieve, it is rich after sieve and Reinforced sieve due to
Compass screen surface pass to material the smaller grade of oscillation intensity can not realize this fine particle stage material (3-13mm) and moist material (3~
30% moisture) effective screening, be replaced by new flip flop screen because cost is high, the cycle is long and the limitation in various transformation spaces is to existing
Process system proposes rigors, it is impossible to meets user to the eager craving of economic benefit, the transformation of individual layer traditional shaker well
Into flip flop screen technology on the premise of screen(ing) machine itself overall structure is not changed, by being arranged indirectly to fixed beam and torsion beam, sieve
While machine screen frame vibrates, driven torsion beam to be moved so that flexible non-metallic sieve plate is tensioned, relaxation it is dynamic
Make, material is obtained very high acceleration in compass screen surface, make material looser, it is easier to sieve thoroughly, perfectly solve common
Screen(ing) machine must be replaced by new flip flop screen and could ask what fine particle stage material and viscosity, the dry type of water content higher building material sieved
Topic.Do not destroyed in original vibrosieve equipment, under the principle that existing process link is not changed, meet user to by original
Short, flat, the fast craving of economic benefit lifting, under existing economic technology means, individual layer list are just realized in the technological transformation of screen(ing) machine
When the oscillation intensity of mass vibrating screen(ing) machine is less than 5g, reliability and economy are optimal, but can not effectively carry out fine particle stage material
Screening.On the premise of equipment global reliability and economy is ensured, flip flop screen technology is transform as by individual layer traditional shaker,
The compass screen surface oscillation intensity of screen(ing) machine is improved, finally realizes the high efficiency screening of fine particle stage material.Simultaneously with the big vibratory sieve of individual layer elemental body
Machine (such as high-amplitude screen, it is rich after sieve, Reinforced sieve) compare, due to the single driving of use, considerably reduce equipment energy consumption itself,
Original screen(ing) machine is fully used, and avoids the waste of original assets.
Enterprise has used relatively conventional individual layer elemental body banana screen to carry out fine-graded screening in link is sieved at present,
Because equipment has the defects of intrinsic, defect is：Can not carry out moist material (table water be 3~30%) and fine granularity (3mm~
13mm) the high-effective classifying operation of material, therefore a higher sieving capacity can not be reached, make production unit if it is desired to obtaining
Higher screening it is horizontal must procuring equipment changed, procuring equipment needs substantial contribution while caused the spare time to existing equipment
Put and waste, be lost in so as to produce fixed assets, the design concept that individual layer traditional shaker is transformed into flip flop screen can be existing
Transformed on the basis of individual layer plastid banana screen, technology upgrading is carried out in the case of relatively low input, it is same after the completion of transformation
It is even more excellent that the screening level of currently used efficient flip flop screen can be reached, but improvement cost is well below tension and relaxation sieve apparatus
Acquisition cost, input cost of the enterprise to device product is effectively reduced, increase productive profit.
Utility model content
