Description
Technical field
The utility model is mainly concerned with the screening plant field, refers in particular to a kind of bar screen.
Background technology
The existing vibratory sieve that is applied to metallurgy industry has oval-shaped equal-thickness vibrating screen, the Suspension arm sieve of common straight-line oscillation.
Existing oval-shaped equal-thickness vibrating screen, compass screen surface is the fritter compass screen surface of casting, and compass screen surface is divided into multistage, and every section compass screen surface is in same plane, and sieve aperture is lambdoid elliptical closed formula sieve aperture, and the compass screen surface percent opening is low, and sieve aperture easily stops up, and influences screening efficiency.Vibrator shakes on being external and is embedded in two kinds of versions on the side plate, on the external that shakes be on inserted basis, to improve and come, screen(ing) machine is bulky, take up an area of big, the cost height.Existing oval-shaped equal-thickness vibrating screen, screen(ing) machine is huger, power of motor is big, two-stage vibration isolation must be arranged, the vibrator position is than higher, need the structure of screen(ing) machine durable, and the compass screen surface percent opening of cast type is low, and Heavy Weight, compass screen surface are installed on the square beam of screen(ing) machine, and ore is all bigger to the wearing and tearing of compass screen surface and crossbeam, cause the weight and the structure of screen(ing) machine huge, thereby cause the energy consumption of screen(ing) machine big yet, the seal closure of this kind screen(ing) machine does not participate in the vibration of screen(ing) machine, between will poorly sealed reality, the environmental protection condition of screen(ing) machine is not so good.Make the environment-friendly type oval-shaped equal-thickness vibrating screen, the power of motor and bearing specification will increase, and large-scale screen(ing) machine bearing is difficult to choose, and make environment-friendly type and also have certain difficulty.
Common straight-line oscillation Suspension arm sieve (bar screen), the rod compass screen surface is open structure, and the common compass screen surface of above-mentioned oval-shaped equal-thickness vibrating screen is the structure of sealing.The opening of rod compass screen surface is that it has very high percent opening, even the critical particle jam is also washed away down by unclassified stores easily, reduces plug-hole, improves saturating sieve probability.During the work of rod compass screen surface, except that vibrating with screen frame, the cantilever rod also produces secondary vibration, increases the amplitude of vertical direction, helps the loose of material, increases the saturating sieve probability and the translational speed of material, improves screening effect.The rod screen cloth has reduced the constraint in the screen cloth cell operation process, and flexible vibration has been eliminated the sealing pit on the common compass screen surface, reduces plug-hole, and screening efficiency is greatly improved.The rod compass screen surface is ladder and distributes, and exists the distance C between the sieve layer to increase the material translational speed, improves material to the compass screen surface souring, makes screening efficiency be greatly improved.Bar screen faces down into comb shape, and the pit that does not have silk screen to be interspersed to form makes that slip resistance reduces under the material of compass screen surface, and the particle that blocks can be easy to wash away down.But in existing straight-line oscillation Suspension arm sieve structure, the inclination angle of compass screen surface is a kind of angle, compass screen surface is a monoblock, on the direction of material operation, the wearing and tearing of compass screen surface are inconsistent, and compass screen surface just influences the screening effect of screen(ing) machine as long as a beam fracture occurs or the bigger damage of the local appearance of rod, the disposable replacing of compass screen surface, waste is serious.Existing Suspension arm sieve, the vibration of screen(ing) machine is a rectilinear motion, and compass screen surface is a cantilevered rod structure, and compass screen surface is a monoblock, and along with sieving being fed forward of material, the screening parameter can not be adjusted with the material situation on the compass screen surface.
As from the foregoing, under identical treating capacity, oval-shaped equal-thickness vibrating screen is subjected to the influence of compass screen surface version, the specification of screen(ing) machine is big, needs cover surface big, the big Heavy Weight of screen(ing) machine amplitude, power of motor is big, and the factory building that needs is also bigger, and manufacturing cost and operating cost compare higher.And Suspension arm sieve is subjected to the influence of compass screen surface version, and the screen(ing) machine specification is little, and cover surface is little, and the screen(ing) machine amplitude is little, the material speed of service is fast, and the wearing and tearing of compass screen surface are also fast, but screen(ing) machine is in light weight, and power of motor is little, need factory building also smaller, but screening precision is not high, manufacturing cost and operating cost are relatively low.The screen(ing) machine specification of existing bar screen adopts the many of the wide compass screen surface of 1.5m, surpasses this width, and compass screen surface is widened, and compass screen surface still is a monoblock, increases under compass screen surface and supports the limited amount system of carrying bolt.Owing to be enclosed construction, be not easy to dismounting, the discontinuity of while compass screen surface, the life-span of compass screen surface is influenced, the maximization of screen(ing) machine is restricted, screen(ing) machine adopt dual-purpose one be equipped with many.Also have, sieve in order to satisfy high throughput, bar screen is designed to diamond structure, though structure is compact, the maintenance inconvenience must adopt the travelling car form, and the uneven situation of cloth appearance, easy material partially, and the track of vibration is not easy to transport material about being.
