Regarding to the simulation results, to confirm the strength and stiffness analysis regarding the spiral conveyor regarding the first failure modes and dangerous position and changes in leaf thickness spiral conveyor impact strength and stiffness. The conclusions showed that: the existing structure can basically meet the creation requirements, while leaf thickness is provided optimal solution for the structural creation of centrifuge valuable theoretical reference. Keywords: screw conveyor; structural analysis; virtual prototype; finite element; blade thickness CLC number: TH237 Document code: A As the local economy and the rapid development of environmental awareness regarding the enhanced capacity regarding the centrifuge, separation efficiency, saving energy, etc. have grow to increasingly demanding, how to improve the position of product creation and shorten the new product development cycle and accelerate the upgrading of existing products, has grow to an above priority. Clearly, the general creation method [1], can not meet the new situation, should be used, for example optimal design, finite element method for static and dynamic analysis, Computer CAD and other advanced Technology [2]. Screw conveyor is the first component Decanter centrifuge, screw conveyor within the static analysis, based on distant analysis and optimization of creation parameters, to Decanter is of good works in practice. Virtual prototype (VP, VirtualPrototyping) technology spiral conveyor static, dynamic performance simulation studies to Pro / Engineer Software Like a platform, the product of parametric solid modeling, through the establishment of a reasonable simplification regarding the virtual prototype screw conveyor, the finite element method, the finite element simulation software MSC.VisualNastran within the spiral conveyor regarding the kinematic simulation, model simulation and stress, deformation simulation, are multi-stage screw conveyor natural vibration frequency, vibration mode and the stress, strain and displacement changes, checking screw conveyor to the strength and rigidity of purpose, and distant analysis regarding the spiral conveyor The first failure mode and dangerous position, based on analysis regarding the conclusions regarding the spiral conveyor structure creation optimization. two load and boundary conditions 1.1 load Screw conveyor within the first course of their work load to bear the following three: (1) due to the fact that of its high-speed rotation and centripetal force generated; (2) The separation moderate (sludge) applied to the spiral blade regarding the positive pressure; ( 3) The separation moderate (sludge) applied to the friction regarding the helical blade. Strictly speaking, spiral conveyor tools also bear its own gravity, but Decanter centrifuge with high separation factor, that is, screw conveyor velocity of gravity is distant fewer than the rotation due to centripetal force generated, so the calculation and simulation the process, ignored the effect of gravity. 1.2 Boundary Conditions Spiral conveyor within the cylinder as the 3 ends were connected with the left and right journal, journal bearing about within the drum bearings on the inside close cavity. Therefore, based on the actual conditions, the model is about supporting the rotation imposed to the constraint. Spiral conveyor regarding the strength confirm of compression vessel reference creation [3]. Screw conveyor regarding the fabric as some kind of alloy material, the simple allowable stress of 20 Sm 3M Pa. As the screw conveyor and the drum regarding the minimum clearance is 4mm (bilateral), so this analysis should be 2mm screw conveyor like a learn based on the radial deformation. 3 Virtual Prototype Modeling and Dynamics Simulation Virtual prototype is set up with advanced CAD modeling techniques consistent with the physical prototype Digital Three-dimensional model, and then use the virtual prototype model regarding the dynamic simulation. Screw conveyor regarding to the actual existing structure, applications and three-dimensional Parametric Technology Pro / Engineer [4] software, the establishment regarding the drum, screw conveyor components and bearings inside the three-dimensional model, and then simplified like a whole, and the model The Boss, chamfering, bolt holes and other features for processing, does not think about the characteristics regarding the welding seam [5]. This can keep unnecessary constraints, stay away from creating use of too large and complex Motor VP model, through the common data exchange standard – STEP into the model the finite element simulation software MSC.VisualNastran [6] in Figure 1, the virtual prototype model, the definition of material, respectively, Elastic modulus, Poisson's ratio, density and other related fabric properties, the definition of speed, compression and other mechanical parameters being and hobbies vice and boundary conditions for motion simulation, are screw conveyor and the movement trajectory regarding the Deputy regarding the force conditions in which the each side bearing stress analysis results, shown in Figure 2. 4 Modal Analysis The learn is to analyze the spiral conveyor assembles the free mode, the first parameters of fabrics consistent with the previous simulation, in which the damping coefficient is 0.01, total mass 409.0Kg. As Decanter is a rigid rotor shaft, rotor velocity is decreased than first order critical speed, so the more practical concern is first 3 natural frequencies and modes. Considering its own gravity and boundary conditions, screw conveyor unit with tetrahedral mesh, the finite element model of a total of 75,430 nodes, 38,451 units, of which first 3 modes of stress and displacement in Figure 3, Figure 5 said. Modal analysis of primary conclusions (see Table 1). When the screw conveyor within first natural resonance frequency, the volume regarding the cylinder within the tube (ie axis) and the straight section regarding the junction of a larger leaf deformation has obvious bending regarding the natural frequency also corresponds to the order the critical speed, by the finite element modal simulation analysis, the screw conveyor first natural frequency is 282.4Hz, the corresponding critical velocity for the 13944r/min. As the screw conveyor creation velocity is 2742r/min, distant fewer than the critical speed, so, screw conveyor velocity within the normal section of resonance does not occur. 5 Strength Stiffness Regarding the screw conveyor to load and full load condition of static analysis, full load condition for the positive pressure, friction, centripetal force regarding the linear combination. This is the condition of all the highest many worthy of concern. Figure six and Figure seven were loaded with the stress condition screw conveyor and radial deformation of cloud. Within the full load condition the maximum stress occurs at the large end helical screw conveyor blades start . Bookmark the .

Ryson Dual Lane Spiral Conveyor will Help Balance Line Flow ...

Apr 27 Going over the Ryson maintenance manual during the FAT of a Ryson Dual Track Spiral Conveyor This week we hosted another factory acceptance test (FAT) for The Jelly Belly Candy Company of Fairfield, California.  Our Systems Integrator, Sierra Conveyor Co., Inc, designed an upgrade to the Jelly Belly case conveyor system that delivers product to their robotic case palletizers.  The new system uses a high speed lane divider prior to the spiral conveyor to automatically meter cases to one of the dual spiral's lanes. This will help to balance the product flow to the three palletizers, speeding up their packaging lines. The new spiral conveyor will also save floor space by replacing conventional incline conveyors. When the incline belts were worn, cases would often slide backwards. With the experienced Ryson engineering team, the spiral's incline angle and built-in friction surface was designed to ensure the correct orientation and smooth transportation of the Jelly Belly cases through their 10 foot elevation change. The spiral will also be prominent on the Jelly Belly factory tour, so your can see it run if you decide to visit. Stay tuned on more details and video on this project once the line is installed.

Has this conveyor belt situation ever happened to you?

You are in line at the store, unloading your items onto the conveyor belt. You have not finished. There is more to unload. The person behind you puts the divider down and begins unloading their things. In effect, this leaves you with less and less room to finish unloading, as the conveyor moves everything forward. Votes Answer 8 No 2 Yes 1 No, but something similar 0 Other User Comment Galomorro posted 26-Apr-2012 2:46pm   No. But sometimes they don't provide enough of those divider thingies so you have to wait until another is available to separate your stuff from another person's. I just stack them if there's not much room. If there are wine or other bottles, sometimes the thing starts up with a jerk and topples the bottles, so I'm apt to lay them on their sides for safety. cerealkiller posted 26-Apr-2012 3:09pm   All the time. And conversely, most people in front of me are the one's who put down the divider so I can start unloading my cart. LJD posted 26-Apr-2012 6:16pm   No Biggles posted 26-Apr-2012 6:25pm   No, I put my things onto the belt from the end (where the space to put my basket is) so there isn't space for anyone to start unloading until I am finished. I've never seen anything like the scenario described here. jen posted 26-Apr-2012 8:48pm   we go together to the store, which makes it easy to effectively block most encroachment LindaH (reply to Biggles) posted 26-Apr-2012 9:45pm   are you standing ahead of your cart or behind it?
