Abstract
The invention relates to an insulator vacuum pugging method and an insulator vacuum pugging device. A center hole of a three-blade tail end spiral blade of a pugging machine and a tapered end of a tapered pugging bowl body are respectively provided with 1-2 plane bearing(s), and the tapered pugging bowl body is connected with the three-blade tail end spiral blade of the pugging machine by a high-intensity pull chain. After the insulator vacuum pugging method and the insulator vacuum pugging device are used, the tapered pugging bowl body is always under the suspension status at an outlet of the pugging machine through the pull chain, when the pugging machine is started up to run, the pug can uninterruptedly and evenly move to a tapered pugging machine bowl body from the periphery. Therefore, the tapered pugging machine bowl body can be always arranged in the middle of the outlet of the pugging machine, a hollow pug section inner hole which is extruded under vacuum can never be eccentric, and ripples can not be available. The pug section pug extruded by the method is even in density, and compact in molecular structure, a formed semi-product is difficult to bend, and a sintered product can not be deformed.
Description
Technical field
The present invention relates to a kind of insulator vacuum pugging method and device thereof.
Background technology
Along with the develop rapidly of power industry, the demand of high pressure, super-pressure electrical equipment equipment transformer, breaker, arrester, transformer, arrester increases sharply.These high pressure, super-pressure electrical equipment equipment are hollow straight barrel types with the insulator great majority, and two ends all adopt aluminum alloy material glue notes flange to be used for connecting.
This high pressure of production and processing, the common mud section extruding method of the hollow bushing insulator of super-pressure straight barrel type are according to its pugging earthen bowl of insulator internal diameter size design, and adopt solid connecting rod to be connected on the terminal spiral leaf of vacuum deairing machine in the pugging earthen bowl.In the time of in pug inserts the pug mill stirring port, the noodles shape that becomes Ф 5-8mm size along with motor transmission pug after stirring enters vacuum chamber, extruding forward after the vacuum, because solid connecting rod has connected the pugging earthen bowl in the middle of the sand pump, it is suspended in the middle of the mud section, therefore all the time, in the middle of the mud section that extrudes out is hollow, be that the building core of same size is clamp-oned mud section intermediate hollow hole from an end toward next procedure again, it coincide put in place, just can begin moulding.
The hollow mud section that adopts this method to extrude out because the connection of taper pugging earthen bowl is to adopt solid iron staff connecting rod, and when the mud section extrudes taper pugging earthen bowl easily along with rotation.Thereby be easy to cause the mud section skewness that extrudes out, and the even interstitial hole of density unevenness departs from the center, and it is thick to form one side, on one side thin.And endoporus presents the scrambling ripple, and is obstructed smooth.After the mud section moulding of this phenomenon, dry in the shade and the drying room dry run in can be crooked.Its crooked rule is that the thin one side of mud section tilts to the thick one side of mud section.Obviously, this is owing to pugging off-centre causes.When this situation occurring, have a strong impact on ordinary production and business economic benefit.
Summary of the invention
Purpose of the present invention just provides a kind of a kind of insulator vacuum pugging method and device thereof that overcomes the prior art defective.At above-mentioned mud section eccentric phenomena, how the way of solution makes taper pugging earthen bowl be in pug mill outlet centre position all the time if should being explored emphatically.
Technical scheme of the present invention realizes that by following approach concrete grammar of the present invention is the first step, at the centre bore of the terminal spiral leaf of pug mill three leaves and the tapering point of taper pugging earthen bowl 1-2 dish plane bearing is installed respectively; Second step, change being connected of the terminal spiral leaf of taper pug mill earthen bowl and pug mill three leaves into high-strength towing chain connection by solid irony connecting rod; The 3rd step, be 300-400mm with the flat length adjustment of stretching the position of taper pugging earthen bowl; The 4th step, an end of high-strength towing chain is welded on Ф 25-30mm, is connected with three leaves end spiral leaf on the member of the circular and band screw of long 50-80mm, the other end is connected with taper pugging earthen bowl; The set screw of the 5th step, the high-strength chain of employing adjusts to the plane of taper pugging earthen bowl than the low 5-10mm of pug mill outlet; The 6th step, thickness of employing are 10-15mm, and diameter and pug mill export carbon knot iron plate of the same size, and cylindrical is opened 6-8 " U " shape mouth as dashboard, before starting pug mill this dashboard is connected capping with the pug mill exit face with bolt; The 7th step, start vavuum pump, move 10-20 minute, vacuum is restarted pug mill after reaching 0.097MPa ~ 0.1MPa, and pug to be added extrudes the pug mill outlet when tin saturated, and dashboard is removed; The 8th step, add pug continuously, when waiting to extrude the mud section and not adding layer, begin formal vacuum pugging.
The device of realizing above-mentioned steps contains pug mill, wherein, at the centre bore of the terminal spiral leaf of pug mill three leaves and the tapering point of taper pugging earthen bowl 1-2 dish plane bearing is installed respectively, between the terminal spiral leaf of taper pugging earthen bowl and pug mill three leaves, is connected by high-strength towing chain.
The present invention is because the towing chain is in suspended state in the pug mill exit all the time with taper pugging earthen bowl, and when pug mill startup work, pug will move to taper pug mill earthen bowl direction from periphery uninterrupted and again equably.Therefore, taper pug mill earthen bowl will be in the centre position of pug mill outlet all the time.Therefore, the hollow mud section endoporus that vacuum extrudes out all the time can be not eccentric, do not have ripple again.The mud section pug density that this method extrudes out is even, molecular structure is fine and close, and the semi-finished product after being shaped are not flexible, can not be out of shape after burning till yet.
Under normal conditions, the mud section semi-finished product qualification rate that the employing conventional method will extrude out is generally between 60-65%, between the porcelain inspection qualification rate 75-80%, and adopt take out the method for draging chain connect the mud section moulding that taper pugging earthen bowl extrudes after qualification rate can reach 85-95%, porcelain inspection qualification rate 90-95%, can improve semi-finished product qualification rate about 20%, sintering qualified rate improves about 15%.Calculate by the production scale of producing 10000 straight barrel type insulators per year, can improve about 2000 of semi-finished product passing numbers in 1 year.Improve 1500 of porcelain inspection passing numbers, the binomial conversion is increased economic efficiency about 2,000,000 yuan, saves pug and consumes about 3000 tons, saves the about 3500 tons of standard coals of mark coal.Save about labor 5000 working days.
