Specific embodiment
Below in conjunction with drawings and the specific embodiments, the invention patent is further described, these embodiments are only used for
Illustrate the present invention, is not limiting the scope of the invention.
Embodiment of the method
High humidity, high viscous material are delivered into dynamic arc sieve apparatus by feed inlet 19.Since device inclined is placed,
From the horizontal by 10-15 °, in the case where continuous feed, material is from a high position to lower position.
By 1 band dynamic crankshaft 2 of motor (or hydraulic motor), the linkage crank 3 of crankshaft 2 and curved bar 4 drive fixing axle 5, by crankshaft
2 circular motion are converted into linear motion.Fixing axle 5 is connect with the swing rod 8 of pendulum slurry system, and the movement band movable pendulum of fixing axle 5 starches system
The arcuate movement for determining angle is done along the arc sifting bed surface being made of round steel 11 and the fixed steelframe 12 of arc, angle is at 90-130 °
Between.Due to the stability that fixing axle 5 moves, pendulum paddle movement is small by material drag effects.
8 top of swing rod is connected to flexible triangle using mechanical suspension system 9 and puts foot 10.The composition of mechanical suspension system 9
It include: that triangle pendulum 10 upper end of foot connect, installation and maintenance convenient feature simple with structure with the bolt that swing rod 8 carries out；
It is equipped with spring in bolt tie point lower end, fillet processing is done in the bottom surface side of triangle pendulum foot 10.When triangle pendulum foot 10 and greatly
When substance contacts, the fillet processing that triangle puts foot 10 guarantees that it, by upward active force, passes through the receipts of mechanical suspension system 9
Contracting, triangle pendulum foot 10 move upwards, surmount big substance and continue operation, to triangle while ensure that the duration of screening process
Shape puts the protective effect that 10 feet play protecting against shock.
The flexible triangle pendulum foot 10 that pendulum paddle end is arranged in connects under the drive of swing rod 8 with the material for entering arc sifting bed
Touching, and angle arcuate movement pressing materials are determined by doing in sieve bed surface.Dynamic arc sifting bed and the triangle pendulum foot 10 of pendulum paddle are matched
Gap setting≤10mm is closed, lesser fit clearance ensure that sifting bed to the screening effect of material.
Nylon bush 13 on arc sifting bed is wrapped on round steel 11.Material is as pendulum paddle is in dynamic sieve bend bed exercise
When, it will drive the rolling of self-lubricating abrasionproof nylon bush 13, form dynamic arc sifting bed.Self-lubricating abrasionproof nylon bush 13 has resistance to
Burn into high temperature resistant, wear-resistant, the low feature of coefficient of friction, the corrosivity that can overcome high moisture material that may have and height are viscous
The big caused feed blocking of material power, kinematic viscosity and knot arch problem.The rolling of the abrasionproof nylon bush 13 of self-lubricating adds
Speed meets the material of various Particle size requirements by sieve, and the discharge port 20 by shining lower object conveying equipment 17 discharges and is transported to
Subsequent processing units, oversize are conveyed using oversize discharging spiral 18, reuse or are handled after the discharging of discharge port 21.
When carrying out the cleaning process of dynamic arc sifting bed, high-pressure spraying equipment is by being mounted on the spray of fixing axle lower end
Pipe 6 and the spray cleaning dynamic arc sifting bed of nozzle 7.Meanwhile starting is mounted on the bi-directional teeth that 11 end of round steel is fixed by support 16
Composition motor 15 is taken turns, motor 15 will guarantee that 14 revolving speed of gear at 300 revs/min or more, guarantees energy when gear set 14 starts turning
Enough round steel 11 is driven to rotate the nylon bush 13 on linkage round steel.The rotation of nylon bush 13 increases cleaning area, makes height
Viscous material is easier to be cleaned by shower water, to improve cleaning efficiency, reduces the use of ejected wash water.Gear set 14 can be into
Row Double-directional rotary further solves the problem of high viscous material difficulty is cleaned.
The dynamic arc screen system of above-described embodiment, be by crankshaft drive cooperation dynamic arc sifting bed realize to high humidity,
The high efficiency screening of the viscous material of height.Meanwhile the height by realizing dynamic arc sifting bed from the cooperation of clear system and dynamic arc sifting bed
Effect cleaning.The dynamic sieve bend bed system has the characteristics that corrosion-resistant, high temperature resistant, wear-resistant, efficient, energy saving.
Finally, it should be noted that being not limited to this foregoing is merely the preferred embodiment of the invention patent
Patent of invention, although the invention patent is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.It is all the invention patent spirit and principle within, any modification, equivalent replacement, improvement and so on,
It should be comprising within the scope of protection of the patent of the invention.
