Description
Technical field
The utility model relates to a kind of heavy-duty plate feeder, belongs to mechanical field.
Background technology
Two BWJ1600*10000 heavy-duty plate feeders of high mouthful iron ore beneficiating factory were installed during the crushing system capacity expansion revamping on July 5th, 2008, and place in operation.They are responsible for the magnetic iron ore in the coarse crushing feed bin is delivered to the conveying task of two the thick chamber of HP500 standard type gyratory crushers respectively.
The working condition of heavy plate machine is: feeding granularity 0-280mm, running velocity is 0.08-0.14m/s, it is the SEW reductor of M4RHF90 that driving system is selected YSP80S-6 frequency control motor (power is 45kw) and model for use, and traffic capacity is the 645-1000t/h. platform, and mounted angle is 6 °.
Material properties: ore density is 3.285 t/m3, and the ore coefficient of volumetric expansion is 1.5, and the ore loose thickness is 2.19 t/m3, and ore hardness is f=14 ~ 18.
The heavy plate machine of BWJ series of Zhejiang Province's Pinghu City constant force machine manufacture Co., Ltd production that use at present in my ore deposit is widely used in cement, industries such as limestone, and good achievement is arranged.The heavy plate of this factory and design belong to main product in the heavy-duty plate feeder industry, but the cement clinker quality is softer, and density is lower, and water ratio is also lower.In my ore deposit production system, because massif infiltration is bigger in the cave drop shaft, cause the raw ore water ratio very high, particularly under the cave in annual rainy season one during the ore deposit, the raw ore average moisture content can reach more than 10%, and a large amount of mud ore deposit is arranged.The hardness of iron ore is much higher than limestone, cement clinker in addition.
After the heavy plate machine of two BWJ1600*10000 in 08 year July is gone into operation, can not adapt to the working condition of my mineral material, fault rate is higher always.In July, 08 to 09, year 7 month to date disorderly closedowns were 109.2 hours, and planned stop maintenance 673 hours is produced needs for satisfying, and equipment often is in the state of providing special care to, the steady production of serious threat crushing system.Annex such as support roller and liner plate is too short service life, changes frequently, and maintenance labour intensity is big.Find that through long-term on-the-spot tracing observation two heavy plate machines use the bigger design defect of existence under my mineral material condition:
1, head cover and following funnel are the branch body structure, and the method that adopts column and crossbeam to support.Because the ore extruding causes the head cover easy deformation, distortion rear shield and following funnel are installed very difficult.Intermediate crusher just had a period of inspection and repair of opening and inspecting main frame, changing liner plate in per 20 days, funnel all needed a large amount of cuttings and welding job amount to waste time and energy under dismounting and securement head guard shield reached when opening and inspecting main frame at every turn, and the repair time that at every turn spends in this position needs more than 6 hours.Head cover is also bad with the sealing of heavy plate side plate, and leakage in service ore deposit is serious.In addition, support the beam strength deficiency of funnel down, often by ore crimp, cause head cover to fall down and cause industrial accident.In 9 months the time of operation of going into operation, once forced down for 8 times, caused unit disorderly closedown accumulative total 56 hours.

3, in the heavy plate machine operational process, the gap between frid and the side plate very easily presss from both sides the ore deposit, and the gusset on the drop end of folder ore deposit promotes ore and travels forward.Higher because of ore hardness, when travelling forward, ore to the following genesis cutting action of the liner plate of side plate, cause wear liner fast especially, and a week can wear and tear about 30mm.Will accelerate to leak the ore deposit behind the wear liner, the service life of a cover liner plate was less than one month.
When pressing from both sides the ore deposit between frid and the side plate, the stressed moment of support roller increases, and causes bearing of conveyor idler to damage because load-carrying capacity is not enough, and the support roller life-span has only 1-3 month.When support roller is changed relatively difficulty waste time and energy, change a complete set of support roller at every turn, need the unit parking maintenance more than 48 hours.
Be extruded gross distortion and caused 5 hours pernicious industrial accident of system shutdown because the big cover of overweight plate side plate and supporting leg once appear in the heavy plate machine of stressed increase 2# behind the folder ore deposit.
4, the lower support wheel Support Position is positioned on the frid both end sides baffle plate, and in the equipment running process, the side shield wearing and tearing are very fast.Use after 10 months, the side shield on the frid grinds off fully, causes leakage ore deposit, production scene serious, and operation two heavy plate machines every day in later stage leak the ore deposit amount and reach the 7-8 ton.
