Description
Technical field
The present invention relates to potter's clay calciner plant, more particularly, to the calciner plant of a kind of potter's clay Automatic Cycle flowing.
Background technology
Existing calcining kiln mostly is rotary kiln, and rotary kiln is by feed arrangement, rotary kiln main frame, fire resistant heat preserving liner, hot blast
Stove and electric control gear etc. form.Wherein, feed arrangement is made up of the defeated machine of feed hopper and spiral shell or feed chute etc., spiral shell transmission of electricity machine by
Frequency Converter Control.Feed arrangement is used for the most controllably being input into material rotary kiln.Rotary kiln main frame by kiln cylinder body,
Bearing apparatus, actuating device, kiln head cover, kiln hood, sealing device etc. form, and are used for heating material and calcining.Fire-resistant guarantor
Temperature liner includes: cylinder fire resistant heat preserving liner, kiln hood fire resistant heat preserving liner and combustor fire resistant heat preserving liner.Air stove is by burning
Device, combustor etc. form, and are used for the fuel generation high-temperature hot-air gas that burns.Electric control gear is by electrical control cubicles, electrical equipment, control unit
Part and primary element etc. form, and are used for the operation of rotary kiln electrical system equipment is controlled and is regulated.
The existing rotary kiln as high-temperature calcination device has that capacity usage ratio is low, calcining heat and the stop of calcined material
The defect such as the time is wayward, product is uneven and occupation area of equipment is big.When especially rotary kiln is as kaolin calcined kiln,
Its shortcoming is more prominent.
Potter's clay raises, because of temperature, the change caused chemically and physically in calcination process.About at 980 degree Celsius, one
Unexpected strong exothermic reaction occurs, the crystallization chemical conversion γ kenel of aluminium oxide, directly forms mullite, in this temperature
The Kaolin that point is calcined out reaches its highest optical brightness, and is typically used as coating or pigment.On this temperature spot,
Product temperature controls to become extremely important.On the one hand, if temperature cannot be stablized at 980 degree Celsius, by cause calcining out
Potter's clay not exclusively converts and causes its calcination product less than optimal brightness characteristic；On the other hand, will lead if temperature rising is the highest
Cause the coarse sand structure of high raw material wearing valve and calcination product, it addition, directly flame impingement also results in such result.
Constantly improvement is carried out in production technology that technical staff calcines at potter's clay and production equipment.Set having calcined
In standby middle correlation technique document, patent documentation [application number: 201010541429.3] discloses one " multiple hearth vertical calcining dress
Put and method for calcinating ", specifically include that furnace shell；The siege that multiple-layer horizontal is arranged, is arranged on inside furnace shell, siege is provided with thing
Material passes through hole；Multiple raker stirrers, are separately positioned on the top of the siege of each equivalent layer；Rotating shaft, is connected with raker stirrer, and drives
Raker stirrer rotates.The vertical method for calcinating of multiple hearth, comprises the following steps: calcining materials is sent into calcining dress from calciner plant upper end
On the siege put；Rotating shaft drives the raker stirrer above siege to rotate, and agitation calcining materials also drives calcining materials to pass through on siege
Material entered the siege of its lower floor by hole, control calcining materials stopping on siege by the velocity of rotation of regulation raker stirrer
Stay the time；Calcining materials sequentially passes through multilamellar siege, and contacts heat with the hot-air that adds moved from bottom to top.This dress
Put complicated structure, can alleviate that potter's clay calcining difficulty is big and the low problem of efficiency to a certain extent, but it is the most briefly
Understanding and machined a series of hole on siege, the relative position relation between Kong Yukong does not describe in detail, but this can affect
To the flowing time of potter's clay granule, eventually affect calcining effect, thus reduce calcining effect, limit its range.
Traditional calcinated argil many employings rotary kiln produces, and thermal source is single, and in kiln, each regional temperature is difficult to detection and is difficult to
Regulation and control, make it difficult to produce the potter's clay product of high request, high added value, and the consideration to details is abundant not, and operating noise is big,
The defects such as action is insensitive, labor strength is excessive.
Summary of the invention
The present invention provides the inner circulation type calciner plant that a kind of bidirectional screw drives, and can accurately control stopping of calcined material
Staying time and calcined material to be heated evenly, longtime running is stable, and service life is long, and easy and safe to operate, technological ability good.
The inner circulation type calciner plant that a kind of bidirectional screw drives, base plate is fixed on ground, and its middle supporting plate is installed on
The both sides of base plate, the top of described fagging installs back rotary kiln outer cylinder body, and described rotary kiln outer cylinder body can be freely rotatable, wherein
Portion secures outer cylinder body bull gear, and outer cylinder body bull gear engages with driving gear, and driving gear is then arranged on normal axis decelerator
Outfan, the input of normal axis decelerator connects servomotor simultaneously, the inwall of aforementioned rotary kiln outer cylinder body and outer wall it
Between main heating wire is installed, internal face is then fixed right-hand screw, relative with described right-hand screw is left-hand screw, rotary kiln outer cylinder body
(4) being provided with center stirring and heating arrangements, the stirring of described center and heating arrangements include heat sink, drive shaft, secondary heating wire
Installing plate, secondary heating wire and left-hand screw, described left-hand screw is fixed on the outside wall surface of heat sink, and secondary heating wire installing plate is fixed on scattered
The two ends of hot plate, are connected with drive shaft again simultaneously, and secondary heating wire is then installed between time heating wire installing plate.
Described heat sink for cylindric, its with left-hand screw not in contact with position be machined with aperture, the shape of aperture is permissible
Selecting as required, circular port is common selection.Described rotary kiln outer cylinder body is divided into inside and outside two-layer, installs between ectonexine
Main heating wire, outer layer is compact structure, and inner plating then machined aperture, in order to hot-air flows at right-hand screw.
The remarkable result of the present invention is:
1, present configuration and operation principle are simple, it is easy to accomplish, make calciner plant have good serviceability.
2, especially prominent advantage is that this device can realize circulating of potter's clay raw material, and meanwhile raw material is by right spiral shell
Rotation falls again when taking rotary kiln outer cylinder body upper end to, and under the driving of left-hand screw, raw material travels forward again, therefore realizes a thing
Circulating of material, raw material is circulated calcining at continuous and hot air simultaneously, until degree of calcination meets requirement is
Only.
3, the rotating speed of servomotor can regulate easily, drives outer cylinder body big by normal axis decelerator and driving gear
Ring gear against rotation, breaks so that the right-hand screw within outer cylinder body bull gear also carries out agitation to it while conveying potter's clay raw material
Broken, meanwhile left-hand screw rotates and then drives potter's clay raw material to move in the opposite direction, thus realizes circulating, and changes calcining
Process and regulation calcining effect.
