Description
Technical field
The invention belongs to construction material production equipment field.Relate to cement/haydite production equipment, specially refer to spiral cement/haydite calcination equipment.
Background technology
Cement is the topmost building cementing material of China.Existing equipment mainly is shaft kiln and rotary kiln, and sum is approximately 7100, wherein just has 5500 to be shaft kiln.This is because shaft kiln technology is simple, small investment, and income is fast, builds than being easier to.And take up an area of seldom, the specification requirement level is low.Its shortcoming is that output is lower, the quality instability.This mainly is because raw material are in static state and burn till in shaft kiln, lacks necessary motion, and the flame inequality causes in the kiln.The improvement of rotary kiln the output of traditional shaft kiln lower, the unsettled shortcoming of quality, big but equipment takes up an area of, investment is big, and the power-equipment power consumption is big.
Haydite is kind of a novel construction material, will produce important function at building field from now on.Yet burning till of haydite mostly adopts the rotary kiln investment bigger at present, the cost height; And general earth kiln is simply equipped and is difficult to guarantee product quality, thereby lacks competitiveness in market.
Summary of the invention
The purpose of this invention is to provide a kind of novel cement/haydite calcination equipment of taking into account, can produce cement and can burn till haydite again.This equipment is on the basis of traditional cement mechanized shaft kiln, adds porous core tube and spiral grate plate in kiln.Utilize porous core tube that air is contacted with raw ingredients; Spiral grate plate can and be fired the abundant preheating of raw material in the kiln.Solved cement mechanized shaft kiln and produced that grog yields poorly, the roasting inequality, ropy drawback.And utilization new type nonaqueous cement kiln tail waste heat reduces the grog energy consumption and the suspension preheating technology that adopts, and energy-saving and environmental protection, efficient, high-quality have also reduced the production cost of cement and building porcelain granule simultaneously.
Technical solution of the present invention is: spiral cement/haydite calcining kiln is by kiln body 1, drawing-in device 2, staged device for discharging 3, hydraulic transmission 4, locking device 5, chimney 6, central porous core tube 7, spiral grate plate 8, blast apparatus 9 and see that material mouthfuls 10 forms.Wherein the kiln body 1, drawing-in device 2, staged device for discharging 3, hydraulic transmission 4, locking device 5 and chimney 6, identical with the corresponding intrument of traditional shaft kiln, add porous core tube 7 at the kiln center, and on porous core tube 7 the spiral grate plate 8 of build-in.See the material mouth in the setting of kiln body.Kiln body 2 also can be produced in factory, arrives on-the-spot assembling then.Kiln body internal diameter is advisable with 1:4 with the ratio of height, and kiln body diameter is typically chosen between the 2.0-3.0 rice, is advisable height 8-11 rice with 2.5 meters.
The cinclides form of wherein central porous core tube 7 is provided with by kiln footpath and clinker quality requirement, and spiral grate plate 8 is that its pass of porous and distribution mode are provided with by material movement and clinker quality requirement.
Effect of the present invention and benefit are that the kiln body ventilates, ventilates, and the raw material of outside not using, realizing under the situation of power-equipment in kiln with spiral grate plate spiral flip-flop movement, raw material preheating, sufficient combustion, clinker quality is good.And easy construction, simple to operate.Make full use of fuel, energy savings.It is a kind of novel concrete/haydite a new generation production equipment that combines traditional shaft kiln and rotary kiln advantage.
Description of drawings
Fig. 1 is spiral cement of the present invention/haydite calcining kiln schematic diagram.
Among the figure: (1) kiln body, (2) drawing-in device, (3) staged device for discharging, (4) hydraulic transmission, (5) locking device, (6) chimney, (7) central porous core tube, (8) spiral grate plate, (9) blast apparatus, (10) see material mouthful (totally 4).
The specific embodiment
Be described in detail concrete construction procedure of the present invention below in conjunction with accompanying drawing.
Step 1: at first build kiln body 1 by laying bricks or stones, reserve simultaneously and see material mouth 10.Kiln body internal diameter is advisable with 1: 4 with the ratio of height, and kiln body diameter is typically chosen between the 2.0-3.0 rice, is advisable height 8-11 rice with 2.5 meters; Be provided with 4 on the kiln body and see and material mouthful be divided into two groups, position 180 degree of being separated by, wherein one group of horizontal direction of seeing material mouthful is positioned at 1/5th and 3/5ths places of kiln body, and another group sees that the horizontal direction of material mouthful is positioned at 2/5ths and five/everywhere of kiln body.
Step 2: assembling staged device for discharging 3 and hydraulic transmission 4, locking device 5.
Step 3: lift central porous core tube 7 and spiral grate plate 8, central porous core tube lower end is fixed on the staged device for discharging 3, so spiral grate plate 8 is simultaneously on fixing and central porous core tube 7 and the kiln body 1.Central authorities' porous core tube 7, the cinclides form is provided with by kiln footpath and clinker quality requirement, and spiral grate plate 8 is a porous, and its pass and distribution mode are provided with by material movement and clinker quality requirement.
Step 3: assemble other equipment, comprise drawing-in device 2, chimney 6, blast apparatus 9.
Claims (1)
1. spiral cement/haydite calcining kiln is by kiln body 1, drawing-in device 2, and staged device for discharging 3, hydraulic transmission 4, locking device 5, chimney 6, central porous core tube 7, spiral grate plate 8, blast apparatus 9 and see that material mouthfuls 10 forms is characterized in that:
A) central porous core tube lower end is fixed on the staged device for discharging 3, spiral grate plate 8 is fixed on central porous core tube 7 and the kiln body 1 by the helix mode;
B) central porous core tube 7 tube walls are made up of the heat resisting pipe surface solid refractory material of tabernacle, and its pass is consistent with distribution mode, and spiral grate plate 8 is made by heat-resisting steel sheet and plate and the solid refractory material of surperficial tabernacle, and its pass is consistent with distribution mode;
C) the material mouth is seen in the setting of kiln body.
