Abstract
The present invention relates to a large diameter energy-saving mechanical vertical kiln which is composed of a barrel body part, a material discharging part, a drive part, a kiln cover part, a chimney part and a material distributor, wherein the material discharging part is arranged below the barrel body part of the vertical kiln; the drive part is arranged below the material discharging part; the kiln cover part is arranged above the barrel body part of the vertical kiln; the chimney part is arranged above the kiln cover part, and the material distributor is arranged in the kiln cover part; ground pins of the chimney part and section ground pins on the kiln bottom are fixed by ground bolts, and ground pins of a large gear cover, a vertical shaft, a worm speed reducer, a motor and a speed reducer in the drive part are fixed by pin bolts. The present invention is characterized in that the diameter D of the vertical kiln is larger than 3.6 m and smaller than 8.2 m. The ratio of the height H of the vertical kiln to the diameter D of the vertical kiln is 0.8 to 2.5:1. The present invention has the advantages of low investment, obvious effect, obvious electricity saving effect, favorable clinker quality and high clinker productivity.
Description
Technical field
What the present invention relates to is a kind of large diameter energy-saving mechanical vertical kiln, belongs to the cement constructional material technical field,
Background technology
Existing shaft kiln is big because of its ratio of height to diameter, and its flowing resistance is bigger, and major diameter shaft kiln windage is difficult for balance, and power consumption is higher, and equipment and construction investment are bigger.
Summary of the invention
The objective of the invention is to the defective at above-mentioned existence, propose a kind of large diameter energy-saving mechanical vertical kiln, it has, and ratio of height to diameter is little, and its flowing resistance is less, and to the easy balance of major diameter shaft kiln windage, power consumption is low, and equipment and construction investment are few.
Technical solution of the present invention: its structure is to comprise shell portion, the discharging part, running part, the kiln hood part, the chimney part, distributing device, wherein discharging partly be arranged on the shaft kiln shell portion below, running part be arranged on discharging part below, kiln hood partly be arranged on the shaft kiln shell portion above, chimney partly is arranged on above the kiln hood part, distributing device is arranged in the kiln hood part, first foundation bolt is the lower margin of chimney part fixedly, the second foundation bolt stationary kiln coxopodite lower margin, drive gear guard lower margin in the first foot bolt fixed conveyor part, vertical shaft in the crus secunda bolting running part, the worm reduction gear lower margin, motor in the tripod bolt fixed conveyor part, the reductor lower margin, the diameter D that it is characterized in that shaft kiln is greater than 3.6m, less than 8.2m, the height H of shaft kiln: the diameter D=0.8 of shaft kiln: 1,1.6: 1.
Advantage of the present invention: reduced investment, instant effect.Reduced equipment investment and kiln room construction investment because kiln height degree is low, reduced the height of conveying equipments such as elevator, thereby reduced the investment of conveying equipment.General novel modern shaft kiln and traditional mechanical vertical kiln are relatively invested under the prerequisite of equivalent production capacity and can be saved half; Power savings is remarkable.Descend owing to highly reduce windage, blower fan is interchangeable with the little motor of power, so power consumption is lower, the unit power consumption of kiln is a 8-10KWh/ ton grog, than standard machinery shaft kiln be at half (standard machinery shaft kiln unit power consumption is a 16-20KWh/ ton grog); Clinker quality is good.Because flowing resistance is little, kiln ventilation improves, and helps burning till fast, so clinker quality is good, 28 days compression strength of grog is greater than 60MPa, than the high 5--10Mpa of standard machinery shaft kiln; Grog output height.Because vertical kiln diameter becomes big, and vertical kiln diameter reaches 3.6M, and steady production, make the unit unit-hour output of shaft kiln break through 20 tons/hour on the one hand.On the other hand, because the flowing resistance of kiln is little, making gets angry speeds up, thereby has improved shaft kiln unit's cross section output.
