Abstract
The invention relates to a novel double-barrel rotary kiln, comprising a barrel body, a feeding part, a discharging part and a rotary part, wherein the feeding part comprises a feeding tube, the barrel body comprises an inner barrel and an outer barrel, one end of the outer barrel is provided with an end plate, one end of the inner barrel is positioned in the outer barrel and is supported by an inner barrel supporting tube, and the inner barrel is disconnected with the outer barrel; the other end of the inner barrel is supported by a supporting roller, and the supporting point lies in a plane. The inner barrel is provided with a big head and a small head, and a 0.1-0.2% gradient is formed. The inner-outer double-barrel structure elongates travel distance or material in the kiln. An spacing plate inclining downwards is disposed in the feeding tube make the wet material to be processed smoothly get through the feeding tube and the outer barrel, turn to the inner barrel and sufficiently reversely exchange with the high temperature hot gas flow, thereby realizing drying and dehydration by using a small quantity of energy source.
Description
Technical field
The present invention relates to the equipment of a kind of oven dry, calcining water-containing materials, relate in particular to a kind of rotary kiln.
Background technology
In the calcining and drying process of cement, gypsum and some chemical industry, building material industry, traditional handicraft is all used the monotubular rotary kiln, and is fairly simple, and cost is low, but energy consumption is higher, and efficient is low, and investment was also big when stroke was long.Also see the patent that " double-deck rotary kiln " arranged, but still be the monotubular kiln in fact, just before monotubular, add the pair of lamina kiln hood.
Summary of the invention
The technical problem that the present invention solved provides a kind of energy-saving and cost-reducing little rotary kiln of investing again.
Technical scheme of the present invention is: a kind of rotary kiln; Comprise cylindrical shell, feed part, discharge part and running part, wherein feed partly comprises tremie pipe, and described cylindrical shell comprises inner core and urceolus; One end of urceolus is equipped with end plate; Inner core one end is supported by the inner core stay pipe in urceolus, and inner core does not link to each other with urceolus; The other end of inner core is supported by carrying roller, and the strong point in one plane.Wherein inner core has major part and microcephaly, forms 0,1-0,2% the gradient.
As a kind of improvement of the present invention, be provided with guider in the described urceolus, make material be easy to import inner core by urceolus.Guider is made up of with dull and stereotyped the curved surface frustum, and frustum is fixedly connected with dull and stereotyped, and flat board is fixedly connected on the end plate, and frustum stretches in the inner core, and frustum does not link to each other with inner core.
As further improvement of the present invention, the inboard of urceolus and inner core is equipped with lifting blade, and said lifting blade is a curved slab, is installed in the inboard of inner core and urceolus by two curved-line thread path.
As another improvement of the present invention, in the described tremie pipe dividing plate is installed, increase the stroke on material decline and the thermal current.Described dividing plate is downward-sloping, and an end is installed on two opposite side of tremie pipe; The other end is unsettled.
The structure of the inside and outside bitubular of the present invention's design, the material that can extend makes it fully to carry out heat exchange in kiln body travel.All be provided with the lifting blade of given shape in the inboard of inner/outer tube; In urceolus, be provided with simultaneously guider; And downward-sloping dividing plate is installed in the tremie pipe, making needs the wet stock (chemical gypsum) of processing to pass through tremie pipe, urceolus very swimmingly, turns to inner core; With the reverse abundant exchange of elevated temperature heat air-flow, heavily realize reaching purpose dry, dehydration with a spot of energy.Not only can save energy and reduce the cost, and investment is also little.

The specific embodiment
The present invention extends material in kiln body travel, fully carries out heat exchange, has designed inner core 5 and urceolus 6; Urceolus 6 is a Long Circle cylindrical shell, end sealing, and the other end is a feed end.Be welded with spiral lifting blade 14 in two, in the invention, adopt the bigger two curved-line thread path shop lifting blade 14 of propulsive force; Lifting blade 14 is the circular arc type batten, have lifting many, leak material less, effective advantage; In the urceolus sealed end, design a guider 11, make material be easy to import inner core 5 by urceolus 6; It is one forms for the frustum 12 of curved surface by six, and big women's head-ornaments be flat board 13, is installed in bolt on the end plate 10 of urceolus sealed end of sealing, and the other end of frustum 12 is a tablet, stretches to the inner core feed end.Material changes inner core over to by urceolus easily in the rotary kiln of rotation like this; Establish 2 groups of inner core stay pipes 8 in the middle of the inner/outer tube, is made up of six steel pipes for every group, the tube material employing is high temperature resistant, intensity is high, corrosion resistant steel alloy or stainless steel tube are processed.They are fixed on the central authorities of urceolus firmly with inner core, and not overslaugh material flows in urceolus again.Inner core has major part and microcephaly, forms 0,1-0,2% the gradient, adds the effect of lifting blade, and material is easy to flow to major part from the microcephaly; Thick about the 1 centimeter fireproof coating of wall liner in the inner core, the peripheral hardware heat preserving and insulating material, and adopt boiler plate or stainless steel material high temperature resistant, that distortion is little, guarantee that like this inner core can bear the high temperature about 1000 degree, is out of shape again little. Inner core is supported by 2 groups of inner core stay pipes 8 in urceolus, and major part half part is supported by one group of carrying roller 9, and three fulcrums basically in one plane.
7 preheatings of material (ardealite or other chemical gypsum) input tremie pipe, oven dry, dividing plate 15 increases the stroke on material decline and the thermal current.Material and thermal current fully exchange like this, and the thermal efficiency is very high; Basically reach the purpose of oven dry material.Material gets into rotary kiln urceolus 6 from feed opening, is driven to rotate continuously by urceolus 6 and lifting blade 14 thereof to flow to urceolus 6 sealed ends, all sends material to inner core 5 by guider 11.Generally than about 6 meters of outer tube lengths, the microcephaly is in urceolus for inner core 5; Because the effect material of this gradient and lifting blade is easy to flow to major part from the microcephaly.The elevated temperature heat air-flow and the material that come from the inner core import fully exchange, reach purpose dry, calcining.Simultaneously, tremie pipe is also as blast pipe.Material and thermal current fully exchange like this, and the thermal efficiency is very high; Basically reach the purpose of oven dry material.
The present invention can be applied to the good many-side of chemical industry, building materials industry: can be used for the oven dry of manufacture of cement medium clay soil except the deep processing of artificial (chemistry) gypsum; The oven dry and the calcining of kaolin (particularly Coaseries kaolin); The calcining of the alum stone flour that manufacturing alum is used; Need product of oven dry or the like behind a lot of washings, choosing, the mill.
Except that the foregoing description, the present invention can also have other embodiments.The similar double-barrel structure of all employings realizes that material can fully carry out the technology of heat exchange, and adopts other to be equal to the technical scheme of replacement or equivalent transformation formation, all drops in the protection domain of requirement of the present invention.
