力及對(duì)機(jī)殼的摩擦力作用而不隨螺旋體一起轉(zhuǎn)動(dòng),物料只在旋轉(zhuǎn)的螺旋葉片推動(dòng)下向前移動(dòng)。普通螺旋輸送機(jī)的特點(diǎn)是:結(jié)構(gòu)簡(jiǎn)單、工作可靠、維修方便、成本較低、密封較好 ,并可多點(diǎn)進(jìn)料和多點(diǎn)卸料。研究?jī)?nèi)容擬解決的主要問(wèn)題螺旋輸送機(jī)在各行各業(yè)中應(yīng)用十分廣泛,是一種不可缺少的機(jī)械傳動(dòng)裝置。本次研究?jī)?nèi)容應(yīng)按照當(dāng)今世界各國(guó)螺旋輸送機(jī)及齒輪技術(shù)發(fā)展總趨勢(shì)向著結(jié)構(gòu)簡(jiǎn)單、工作可靠、維修方便、成本較低、密封較好,并可多點(diǎn)進(jìn)料和多點(diǎn)卸料著手。本課題擬解決的主要問(wèn)題:螺旋輸送機(jī)總體設(shè)計(jì)、螺旋輸送機(jī)的計(jì)算計(jì)算(輸送量、物料綜合特性系數(shù)、設(shè)備選型、轉(zhuǎn)速-螺距等)、裝配圖、部分零件圖和三維建模仿真。經(jīng)過(guò)設(shè)計(jì)使得螺旋輸送機(jī)能很好得滿足現(xiàn)場(chǎng)的安裝要求和使用要求,經(jīng)過(guò)改造使得螺旋輸送機(jī)在使用性能、可靠性、方便程度上都有很大的提高。其各方面的性能指標(biāo)均達(dá)到或超過(guò)國(guó)內(nèi)的同類產(chǎn)品。研究方法技術(shù)路線1.在接到螺旋輸送機(jī)設(shè)計(jì)任務(wù)書(shū)后,首先要仔細(xì)閱讀,明確設(shè)計(jì)要求以及所給的各參數(shù),在心中明確一個(gè)大致的設(shè)計(jì)思路。2.通過(guò)閱讀學(xué)習(xí)相關(guān)文獻(xiàn)資料,了解之前的齒輪螺旋輸送機(jī)的設(shè)計(jì)過(guò)程以及學(xué)習(xí)Pro/E,CAD建模繪圖。3.首先確定螺旋輸送機(jī)整體傳動(dòng)方案,分配傳動(dòng)比,選擇電動(dòng)機(jī),確定功率以及各軸的力矩大小,然后進(jìn)行各齒輪、軸的校核。最后設(shè)計(jì)殼體和箱蓋并且選用密封圈、軸承等標(biāo)準(zhǔn)件。4.運(yùn)用Pro/E進(jìn)行三維建模和工程圖的繪制以及運(yùn)動(dòng)仿真。5.結(jié)合國(guó)內(nèi)外已有的螺旋輸送機(jī)來(lái)優(yōu)化并完善自己的設(shè)計(jì)。研究的總體安排和進(jìn)度計(jì)劃寒假

, a flexible screw conveyor consists of a spring steel or stainless steel flexible screw that is enclosed in s flexible or rigid plastic tube or a rigid steel tube (a small diameter ,plastic inner tube may also run the entire length of the flexible screw) and driven by an electric motor,normally located at the discharge end of the conveyor.The intake end of the conveyor tube is typically equipped with a charging adapter-a U-shaped trough that connects to the outlet of a hopper or directly to the outlet of process equipment such as a bulk bag discharger,bag dump station,grinder,crusher,screener,blender,reactor,or storage vessel. The flexible screw passes through the charging adapter troughexposing a section of the screw to material flowing into the trough from above. When rotatingthe exposed section of screw feeds material into the outer tubewhere it is then propelled through the tube by the enclosed portion of the screw.The screw automatically selfcenters within the tubeproviding clearance between the screw and tube wall a phenomenon resulting from the loose fit of a rotating flexible screw within a tube filled with bulk material This property affords sufficient space for particles to flow without damagedepending on the fragility and size of particles being conveyed.A removable cleanout cap covers the intake end of the conveyor tubePermitting rapid emptying and flushing of the tubeas well as disassembly and washdown of components .Because the intake end of the screw requires no bearing,and since the discharge end is coupled to the motor drive above and/or beyond the point at which material exits the discharge spout, material does not come in contact with seals or bearings. The flexible screw is therefore the only moving part contacting material.Typical applications include conveying of materials between storage vessels,bulk bag dischargers,manual bag dump stations,drum dump stations,crushers,screeners,blenders,reactors,Packaging equipment,injection molding and extrusion machines and other Process equipment.Capabilities A flexible screw conveyor is your most likely choice if its list of distinguishing capabilities closely matches that of your requirements,or if an individual capability exclusive to a flexible screw solves an individual problem of key concern. CoMPare your needs with the following attributes。one moving Part contacting materialThe only moving part contacting material in a flexible screw conveyor is rugged flexible screw,which is directly driven by an electric motor. This simple design does not require the filters,cyclone separators ,internal bearings,and other moving parts found on pneumatic conveyors,bucket elevators,rigid augers,drag chains,and/or aeromechanical conveyors .Conveys free-flowing and nonfrce-flowing materials- A flexible screw conveyor can transport bulk materials ranging from large pellets to submicron powders,including difficult to handle products that Pack,cake,seize,fluidize,plug,or smear. Some examples are fine powderssuch as fumed silica,compressible materials such as titanium dioxide,dense materials such as metal powder, friable materials,materials that fluidize,and materials comprised of particle sizes to 1 in. such as nuts. The gentle rolling action created by the rotating screw prevents the separation of blended Products,even those comprised of disparate particle sizes and/or densities,throughout the entirelength of the conveyor.Contamination Prevention-A flexible screw conveyor can be fully enclosed to Prevent contamination of bulk Products and the Plant environment,while Preserving the moisture and temperature levels of materials being conveyed. All interior surfaces are smooth,and can be easier to clean than conveyors in which material contacts internal bearings,seams,filters or other internal components . In addition,the units can be designed and finished to industrial and sanitary standards encoMPassing chemical,pharmaceutical,food/dairy,plastics,paint,mining,packaging,and other applications .Multidirectional-A flexible screw conveyor can move powder and bulk solid materials vertically,horizontally,or at any angle. This ability allows the user to position the intake and discharge ends of the conveyor according to the preferred system Layout or to accommodate awkward layouts as are frequently encountered in retrofit/upgrade situations.Gentle Product handling-Depending on particle fragility and size,a flexible screw conveyor can move materials with little or no breakage ordegradation,Clearance afforded between the screw and tube wall by the rotating,self-centering screw can eliminate or minimize the grinding,crushing,and iMPact damage that can occur with other conveying methods.Rapid,thorough cleaning-Flexible screw conveyors contain no cracks,crevices,filters,or bearings that can trap particles or breed contamination. Cleaning consists of removing the cleanout cap and reversing rotation to evacuate any residual material Prior to flushing with air, water,steam,or cleaning solution. The screw and outer tube canalso be removed rapidly for thorough wash-down of individual components.high reliability, low maintenance-A flexible screw conveyor contains no internal bearings. filters,or separators to wear, break down,or require maintenance. The wear and fatigue-resistant flexible screw is driven directly by an electric motor . Depending on application parameters,a flexible screw conveyor can be started and stopped repeatedly,even under a full load,with no binding or damage to the unit.Economical-The lack of internal bearings,gears,filters,or chains as well as external compressors,blowers,and separators can make flexiblescrew conveyors less costly to build and operate than other conveyors. A flexible screw conveyor can also be economical to install,because theintake and discharge ends can be Positioned wherever desired,without exact conveyor routing,reducing the need to reconfigure other upstreamand downstream Process equipment.Mobility-Flexible screw conveyors can be caster-mounted on frames with conveyor support booms for inplant mobility,avoiding the cost of multiple stationary units.Multiple discharges-Horizontally oriented flexible screw conveyors can feed multiple packaging machines,molding machines,and processequipment simultaneously or individually They can also convey bulk material over long distances,feed multiple discharge points selectively,or top off all Points on a timed cycle through manual or automatic slide gate valves.Volumetric feeding-A flexible screw conveyor can simultaneously meter and convey bulk solid products Units can be equipped with ac or dc variable-speed drives and hoppers with flow promotion devices for continuous feeding of both free and nonfree-flowing materials.Weigh batching and feeding-Gain-in-weight batching systems consist of individual or multiple flexible screw conveyors discharging into a central weigh hopper or other process equipment,which is equipped with load cells. Gain-in-weight information is transmitted to a central programmable controller,which in turn controls each conveyor. The controller then activates each conveyor,in sequence,to load each ingredient into the central weigh hopper,first at high speed,then at dribble speed before stopping the conveyor when the target batch weight has been reached. since the system functions as both weigh feeder and conveyor,it can eliminate the need for separate equipment. LimitationsSince every mode of conveying also Possesses inherent limitations,each must be identified and ruled unimportant,or less important than corresponding attributes,before deeming a flexible screw conveyor to be the most compromise-free alternative for your application.Material evacuationFlexible screw conveyors,like other mechanical conveyors,do not generally evacuate material completely when operating in a forward direction The cleanout cap can be removed,however,and the screw rotation reversed to fully evacuate residual material for reasons of cleaning and/or material changeovers. Gentle Product handlingWhile flexible screw conveyors can have less deleterious effect on materials than do methods that tend to grind,crush,or iMPact bulk products,not all materials can be conveyed damage一free. A Percentage of large,brittle flakes or large,soft particles may,for example,incur breakage,particularly through long runs or steep inclines in a flexible screw conveyor . proper engineering of a flexible screw conveyor system can eliminate or minimize these effects.Capacity requirementsFlexible screw conveyors are currently utilized for applications with capacity requirements less than 50 tons/hr ( Per conveyor ) , explaining why they are infrequently employed for off-loading of ships or railcars. Other eonsid6rationS there are two basic types of screws in flexible screw conveyors: round wire and flat wire. Each has its advantages and limitations. The rounded flight surface of round wire screws iMParts the material with directional forces that propel it through the tube,and relatively high radial forces that create an effective bearing between the screw and tube wall througho
