Abstract
The utility model relates to a porcelain sleeve vacuum pugging device which comprises a pugging machine, wherein one to two surface bearings are respectively installed in a center hole of a helical blade on the tail end of three blades of the pugging machine and on the conical end of a conical pugging bowl and connected between the conical pugging bowl and the helical blade on the tail end of the three blades of the pugging machine by high-strength drag chains. According to the porcelain sleeve vacuum pugging device, because the conical pugging bowl is in a suspension state all the time in an outlet of the pugging machine by using the drag chains, when the pugging machine is started to operate, pug continuously and uniformly moves to the conical bowl of the pugging machine from the periphery, therefore, the conical bowl of the pugging machine is in the middle position of the outlet of the pugging machine all the time, and inner holes of hollow pug sections which are extruded in a vacuum mode cannot be eccentric all the time and does not have crinkles. The pug of the pug sections which are extruded by using the method has the advantages of uniform density and compact molecular structure, and a formed half-finished product is difficult to bend and cannot deform after sintering.
Description
Technical field
The utility model relates to a kind of insulator vacuum pugging device.
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 to annotate flange for connecting.
This high pressure of production and processing, the common mud section of the hollow bushing insulator of super-pressure straight barrel type extruding method are according to its pugging earthen bowl of insulator internal diameter size design, and adopt solid connecting rod to be connected on vacuum deairing machine end helical-blade 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 the motor-driven pug after stirring enters vacuum chamber, extruding forward after vacuum, because solid connecting rod in the middle of sand pump has connected the pugging earthen bowl, it is suspended in the middle of the mud section, therefore all the time, hollow in the middle of the mud section that extrudes out, be that the building core of same size is clamp-oned the middle hollow hole of mud section from an end toward next procedure again, it coincide put in place, just can start 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 being easy to cause the mud section skewness that extrudes out, the even interstitial hole of density unevenness departs from center, forms one side thick, 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 because pugging bias causes.While this situation occurring, have a strong impact on normal production and Business Economic Benefit.
Summary of the invention
The purpose of this utility model just is to provide a kind of a kind of insulator vacuum pugging device that overcomes the prior art defect.For above-mentioned mud section eccentric phenomena, how solution makes taper pugging earthen bowl be in all the time pug mill outlet centre position if should being explored emphatically.
The technical solution of the utility model realizes by following approach, the utility model contains pug mill, wherein, at the tapering point of the centre bore of pug mill three leaf end helical-blades and taper pugging earthen bowl, 1-2 dish plane bearing is installed respectively, is connected by high-strength towing chain between taper pugging earthen bowl and pug mill three leaf end helical-blades.
The utility model is in the pug mill exit taper pugging earthen bowl suspended state all the time due to the towing chain, 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 again ripple.The mud section pug even density that this method extrudes out, molecular structure densification, 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 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 20% left and right, sintering qualified rate improves 15% left and right.Calculate by the production scale of producing 10000 straight barrel type insulators per year, can improve 2000 left and right of semi-finished product passing number in 1 year.Improve 1500 of porcelain inspection passing numbers, the binomial conversion is increased economic efficiency approximately 2,000,000 yuan, saves pug and consumes approximately 3000 tons, saves approximately 3500 tons of standard coals of mark coal.Save about labor 5000 working days.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein: three leaf end helical-blades 1, taper pugging earthen bowl 2, plane bearing 3, high-strength towing chain 4.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing
The utility model contains pug mill, wherein, at the tapering point of the centre bore of pug mill three leaf end helical-blades 1 and taper pugging earthen bowl 2,1-2 dish plane bearing 3 is installed respectively, is connected by high-strength towing chain 4 between taper pugging earthen bowl 2 and pug mill three leaf end helical-blades 1.
Concrete pugging, adopt the following methods step:
1, at the centre bore of pug mill three leaf end helical-blades 1 and the tapering point of taper pugging earthen bowl 2,1-2 dish plane bearing 3 is installed respectively, specifications and models are 51304 or 51306.
2, change taper pug mill earthen bowl 2 and being connected of pug mill three leaf end helical-blades 1 into high-strength towing chain 4 by solid irony connecting rod and connect, its specification is 80 grades of hoisting chain 6x8 or 7x21.
3, be 300-400mm with the flat length adjustment of stretching position of taper pugging earthen bowl 2.
4, an end of high-strength towing chain 4 is welded on Ф 25-30mm, long 50-80mm circular and with being connected with three leaf end helical-blades 1 on the member of screw, the other end is connected with taper pugging earthen bowl 2.
5, adopt the set screw of high-strength chain 4 that the plane of taper pugging earthen bowl 2 is adjusted to than the low 5-10mm of pug mill outlet.
