Abstract
The invention discloses a quick lime slurry digester. The quick lime slurry digester comprises a digestion box body and a rotation shaft which is driven by a drive device and provided with stirring blades; the upper part of the rotation shaft is provided with a shaft seal; the key points are that the rotation shaft is arranged slantly, the angle between the rotation shaft and the horizontal plane is 10 to 80 degrees; the upper part of the rotation shaft is provided with a conveying spiral; a sealing box body with a feed port is sleeved on the conveying spiral; and the side of the digestion box body is provided with a slurry overflowing port which is lower than a bearing of the rotation shaft and the shaft seal. According to the quick lime slurry digester, the slant rotation shaft is adopted, so that the bearing is positioned above digestive liquid and is not directly contacted with the digestive liquid, and the problems of low sealing performance of a shaft end and blockage of the feed port in the slurrying process of quick lime can be effectively solved; and meanwhile, due to the adoption of the upper-lower-upper periodic continuous stirring action, the processes of heat and mass transfer between media in the digester can be enhanced, the slaking reaction of the quick lime is enhanced, the deposition effect of slurry and slag particles is inhibited, and the quality of slaked lime slurry is improved.
Description
Technical field
The present invention relates to a kind of burnt lime digester.
Background technology
Unslaked lime slurry formula digestive organ is widely used in the industries such as flue gas desulfurization, sintered material, made industry, the control of industrial pH value, incrustation scale control, softening water, sludge treatment, paper pulp papermaking technology, light calcium carbonate manufacturing.There are 2 distinct issues in traditional unslaked lime slurry formula digestive organ: rotation axis sealing difficulty, opening for feed are prone to stop up.Quicklime slaking reaction generates a large amount of steam, add the stirring action of slurries and the moisture absorption three acting in conjunction of unslaked lime are made that opening for feed is easy to stop up that along with the raising that digests temperature, latch up phenomenon is more obvious; Because the slurries band slag in the digestive organ has the characteristics that corrodibility and wearing and tearing are washed away simultaneously, thereby require very high to the axle envelope; The burnt lime digester that is limited by the vertical shaft layout exists slurries layering, slag inclusion to be prone to deposition, digests problems such as incomplete; The mode that existing quicklime slaking machine generally adopts transverse axis to arrange; Slurries directly contact with the axle envelope, are difficult to overcome the problem of rotation axis sealing, are prone to a leak sealing slurry, axle and bearing wear problem; For the big unslaked lime of dregginess, the shaft end seal problem is more outstanding.
Summary of the invention
The purpose of this invention is to provide the good unslaked lime slurry formula digestive organ of a kind of bearing seal.
To achieve these goals; Adopt following technical scheme: a kind of unslaked lime slurry formula digestive organ; Comprise digestion casing and the rotation axis with agitating vane that drives through drive unit, the top of rotation axis has the axle envelope, and it is characterized in that: said rotation axis is for being in tilted layout.
The angle of said rotation axis and level is 10 ~ 80 °.
The input of unslaked lime for ease, the top of said rotation axis is provided with conveyor screw, is with the seal case with opening for feed on the conveyor screw.
For fear of too high bearing and the axle envelope of flooding rotating shaft of liquid level, the side of said digestion casing is provided with the excessive mouth of starching, and the height of the slurry mouth that overflows is less than a rotation axis bearing and a height that seals.
The maintenance of digestive organ and cleaning for ease, said digestion casing top is provided with venting port, and the bottom is provided with slag-drip opening.
The present invention adopts the rotation axis of inclined, makes the density of bearing be positioned at the top of Digestive system, is not in direct contact with it; Effectively solve shaft end seal, opening for feed blockage problem in the quicklime slurrying process, can greatly prolong digestive organ work-ing life, improve the flexibility of digestive organ the unslaked lime quality; Simultaneously; Adopt the periodicity of " on → down → on " to continue stirring action, strengthened the heat and mass transfer process between medium in the digestive organ, strengthened the slaking reaction of unslaked lime; The deposition effect that has suppressed slurries and slag particle has improved the quality of white lime slurries.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure, 1 is the digestion casing, and 2 is phonomoter, and 3 is step-down gear, and 4 is rotation axis, and 5 is opening for feed; 6 is water-in, and 7 are the slurry mouth that overflows, and 8 is slag-drip opening, and 9 is venting port, and 10 is supporting seat; 11 are the digestion liquid level, and 12 is bearing, and 13 is conveyor screw, and 14 is agitating vane, and 15 is seal case.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further specified.
As shown in Figure 1; A kind of unslaked lime slurry formula digestive organ, wherein, the main body of digestive organ is supported by supporting seat 10; Phonomoter 2 links to each other with rotation axis 4 through step-down gear 3; The drive rotation axis rotates, and the scope of angle is 30 ° between rotation axis medullary ray and horizontal plane, and digestion casing 1 is in tilted layout with the tilt angle alpha of coupling rotation axis; Rotation axis 4 is conveying, stirring integrated axle, and leading portion is provided with seal section conveyor screw 13, and back segment is provided with agitating vane 14; The end of conveyor screw 13 and agitating vane 14 are immersed under the slurries liquid level, and rotation axis 4, conveyor screw 13 and agitating vane 14 are all taked anticorrosion, wear-resisting measure; In whipping process; Agitating vane 14 produces " on → down → on " to slurries in the digestion casing periodicity continues stirring action; Make slurries that flowing of vertical direction not only arranged, and have flowing of horizontal direction, strengthened the heat and mass transfer process between medium in the digestive organ; Strengthen the slaking reaction of unslaked lime, suppressed the deposition effect of slurries and slag particle; The excessive mouth 7 of starching is arranged at digestion casing middle and upper part, and the position control of starching mouth through overflowing digests the height of liquid level 11; Bearing 12 with axle envelope is arranged in the top of digestion liquid level 11, guarantees that the axle envelope does not take place directly to contact with slurries, fundamentally solves the problem of axle envelope stopping property difference.
The digestion box top is provided with venting port 9, venting port band fly-ash separator, and have negative pressure-pumping power; The outer of conveyor screw 13 is provided with and the close-fitting cylindrical seal casing 15 of conveyor screw; Opening for feed 5 is set on the seal case 15; Under the common influence of the suction function three of sealing function, conveyor screw 13 continuous conveying effects and 9 pairs of digestion casing 1 top steam of venting port of seal case 15; Opening for feed place unslaked lime is bonded to because of basically eliminate, can effectively solve the blockage problem of opening for feed 5.The digestion bottom half is provided with slag-drip opening 8, makes things convenient for the maintenance and the cleaning of digestive organ.
