Abstract
The utility model discloses a cement clinker high-temperature guide machine which comprises a case, a fixed bed and an air inlet pipe. The upper portion of the case is connected with a kiln hood of a calcining kiln. The bottom of the case is installed on the fixed bed. A high-temperature-resistant pouring layer is poured on the portion, connected with the fixed bed, in the case. The air inlet pipe is arranged on the bottom of the fixed bed and communicated with the case. By the utilization of a fixed grate bed structure and by means of heat exchange between cooling air and high-temperature clinker, sensible heat of clinker can be recovered and used for lowering heat loss of a system; the top face of the fixed grate bed is an inclined plane provided with step-layout grate plates, the angle formed by connection lines of vertexes of steps is smaller than a material repose angle, materials can be moved forward easily, a static material layer can be formed on the surface of each grate plate, and the phenomenon that the grate plates are worn by the moving materials can be avoided.
Description
Technical field
The utility model belongs to cement manufacture plant, relates in particular to the high temperature material guiding machine device that white cement clinker is produced.
Background technology
White cement production technology and Portland cement have larger difference, require white cement to who knows in composition will strictly control MgO, SO according to white cement national standard
3and Fe
2o
3content, therefore has relatively high expectations to raw materials for production, and clinker discharging need take water quick cooling bleaching process to improve the whiteness of grog in addition.Due to the particularity of raw material, white cement clinker calcining heat is (approximately 1350 ℃ of Portland cement calcining heats) up to 1500 ℃, and after grog kiln discharge, (~ 1500 ℃), are chilled to below 500 ℃ through bleaching machine shrend, make micro Fe
2o
3be reduced into FeO, ferrous aluminate is with C
6aF
2form occurs, to reduce the C that whiteness is had to adverse effect
4aF content.Due to grog complete sensible heat in white cement clinker shrend process, having become steam evaporation cannot reclaim, and causes white cement to burn till hear rate and exceeds much than Portland cement.
How to improve the utilization rate of grog sensible heat, reclaim heat, reduction white cement burns till hear rate becomes of great value research topic.
Summary of the invention
For the defect existing in prior art and technical problem, the utility model provides a kind of clinker high temperature material guiding machine, can effectively reclaim the auxiliary calcining of grog sensible heat, reduces system hear rate.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of clinker high temperature material guiding machine, comprise the housing that top is connected with calcining kiln kiln head cover, and fixed bed and blast pipe, described housing bottom is arranged on fixed bed, and enclosure interior is cast with high temperature resistant pouring layer; Described blast pipe is located at the bottom of fixed bed and connects with housing.
As preferably, described fixed bed comprises the bellows of hollow and is located at the stepped grate plate with ventilation slot of bellows end face.
As preferably, the summit line angle of described stepped grate plate is less than material angle of repose.
Further improve, the bellows of described hollow are divided into multiple regions, and described blast pipe also comprises multiple airducts that are connected with each region respectively simultaneously.
Further, described high temperature resistant pouring layer is " water chestnut " shape.
Further, the ventilation slot width in described grate plate is less than 3mm, and air-out direction is consistent with flow direction of material.
Further, also comprise hydraulic push rod device and air bubble system.
Further, on every of described blast pipe airduct, be equipped with volume damper.
Beneficial effect: with respect to prior art, the utlity model has following advantage: utilize fixing grate structure, by the heat exchange of cooling air and high temperature chamotte, realize the recovery of grog sensible heat, for reducing system hear rate; Fixing grate end face is an inclined-plane with step arrangement grate plate, and ladder summit line angle is less than material angle of repose, has both been conducive to advancing of material, can form a static bed of material on grate plate surface again, avoids the wearing and tearing of motion material to grate plate.Be furnished with hydraulic push rod device and air bubble system, for the treatment of burning till extremely because of grog, cause the clinker masses are bonding, or "snowman" formation phenomenon.

The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
According to white cement production technology, clinker discharging is since 1500 ℃ of bleachings, and since 1350 ℃ of bleachings, very little on the impact of grog whiteness.Accordingly, the purpose of this utility model, is, between white cement calcining kiln and water-cooled bleaching machine, high temperature material guiding machine is set, before white cement clinker hardening bleaching, first by clinker temperature by 1500 ℃, be cooled to 1350 ℃.And reclaim this part grog sensible heat, auxiliary calcining, reduces system hear rate.
As shown in Fig. 1～2, clinker high temperature material guiding machine, comprises the housing that top is connected with calcining kiln kiln head cover, and fixed bed and blast pipe, and described housing bottom is arranged on fixed bed, and is cast with high temperature resistant pouring layer with the junction of fixed bed in housing; Described blast pipe is located at the bottom of fixed bed and connects with housing, its every supreme volume damper that is equipped with of blast pipe, and be also provided with hydraulic push rod device and air bubble system, for the treatment of "snowman" formation or bulk grog bonding phenomenon.
Fixing grate main body is the hollow bellows of an internal zone dividing, and bellows end face is lined up stairstepping inclined-plane, and the grate plate of a piece band ventilation slot is housed above, and bellows are by general steel plate welding production, inside is divided into several regions, the corresponding air inlet in each region, and air inlet is positioned at bellows bottom.Step inclined plane place, bellows top correspondence air outlet one by one, is equipped with a grate plate above each air outlet.
Shown in Fig. 3, high temperature resistant pouring layer forms " water chestnut " shape structure in fixed bed region, for guaranteeing that grog is from calcining kiln falls, in whole grate, evenly spread out, and guarantees that heat exchange is uniform and stable.Fig. 4 is the enlarged drawing of fixed bed, and along material flow path direction, grate plate is lined up stairstepping from top to bottom, and ladder summit line angle is less than material angle of repose.Grate plate, by casting heat resistant steel, above has waveform ventilation slot, and ventilation slot width is less than 3mm, and air-out direction is along material flow path direction, obliquely.Go out grate plate cold wind and complete heat exchange through high temperature chamotte on the one hand, utilize along the component of material flow path direction on the one hand, supplies advance.Notch cuttype structure can form static bed of material protection grate plate, prevents grate plate wearing and tearing.
