The utility model relates to an environment-friendly calcining shaft kiln applicable to calcining limestone, dolomite, flame resistant raw pellets, metallurgical pellets, etc. materials, which remain solid state after being calcined. The environment-friendly calcining shaft kiln comprises a kiln chamber body provided with a charging opening and a burner nozzle, and the kiln chamber body is divided into a preheating zone, a calcining zone and a cooling zone from top to bottom; an air intake device and a discharging device are arranged at the lower part of the cooling zone; the air intake device comprises an air circular duct arranged on the kiln chamber body and a blast cap which is arranged in the kiln chamber body and is communicated with the air circular duct by a branch pipe. The blast cap is provided with an air outlet; the discharging device comprises a hopper arranged under the blast cap and a vibration discharging machine communicated with the hopper; a material unloading channel is formed between the blast cap and the kiln wall of the kiln chamber body. The environmental friendly calcining shaft kiln has the advantages of stable structure, light weight, less investment, reliable operation and even air intake and material-discharging.
Description
Technical field:
The utility model relates to a kind of environment-friendly type calcining vertical kiln that is applicable to the constant materials of calcining back solid form such as calcined limestone, rhombspar, fire-resistant raw material green-ball, metallurgical briquetting.
Background technology:
At present, at the calcining vertical kiln that is used for the constant materials of calcining back solid form such as calcined limestone, rhombspar, fire-resistant raw material green-ball, metallurgical briquetting, the discharge system of calcining vertical kiln all adopts spiral, first dish, supporting plate or roll-type discharging machine, so just cause weight of equipment big, investment is many, maintenance capacity is big, and is seriously polluted.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of environment-friendly type calcining vertical kiln with unique air inlet device and drawing mechanism is provided.
The purpose of this utility model be achieved in that comprise have charging opening and a burner be divided into the preheating zone from top to bottom, calcining zone, the kiln thorax body of cooling zone, be provided with air inlet device and drawing mechanism in the cooling zone bottom, air inlet device comprises the air bustle pipe that has blast inlet that is installed on the kiln thorax body and is arranged on the intravital blast cap that is connected by arm and air bustle pipe of kiln thorax, on blast cap, be provided with a plurality of air outlets, drawing mechanism comprises the bucket that is arranged on below the blast cap, the vibrations discharging machine that is connected by metallic hose and bucket, for connecting kiln thorax and the endless belt of containing ash bucket, this endless belt is the material blanking channel between the kiln wall of blast cap and kiln thorax body.
Described arm is for supporting the supporting leg of blast cap, and this supporting leg is formed the ventilation duct of bracket shape by two steel plates, is welded on the bucket.
Be provided with annular flue on kiln thorax body top, annular flue is provided with interchanger, and annular flue is connected with extraneous through chimney.
Described kiln thorax body is a round kiln thorax body.
The utility model has the advantages that: weight of equipment light [be about general shaft furnace 1/5], Stability Analysis of Structures does not have rotator in the kiln, do not need repairing, so reduced investment, reliable, the air intake discharging is even.This calcining vertical kiln charging opening also plays " material envelope " effect, and operational condition is good.Belong to the environment-friendly type kiln.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in Figure 1, the utility model comprise have charging opening 7 and a burner 10 be divided into the preheating zone from top to bottom, calcining zone, the kiln thorax body of cooling zone, be provided with air inlet device and drawing mechanism in the cooling zone bottom, air inlet device comprises the air bustle pipe that has blast inlet 1 that is installed on the kiln thorax body and is arranged on the intravital blast cap 3 that is connected by arm 2 and air bustle pipe 1 of kiln thorax, on blast cap 3, be provided with a plurality of air outlets, drawing mechanism comprises the bucket 4 that is arranged on below the blast cap 3, the vibrations discharging machine 6 that is connected by metallic hose 5 and bucket 4, for connecting kiln thorax and the endless belt of containing ash bucket, this endless belt is the material blanking channel between the kiln wall of blast cap 3 and kiln thorax body.
Described arm 2 is for supporting the supporting leg of blast cap 3, and this supporting leg is formed the ventilation duct of bracket shape by two steel plates, is welded on the bucket 4.Be provided with annular flue 8 on kiln thorax body top, annular flue 8 is provided with interchanger 11, and annular flue 8 is connected with extraneous through chimney 9.
Described air bustle pipe 1 is for being looped around the kiln thorax gas passage in external one week.
Described kiln thorax body is a round kiln thorax body.Air bustle pipe 1 is connected by blast inlet and external blower.
Cooling and combustion air are entered by bottom air bustle pipe, enter blast cap through arm [supporting leg], set out the air port on the blast cap, and wind is sent in the kiln from a plurality of air outlets on the blast cap.The blast cap frame is on arm [supporting leg], and supporting leg [arm] is welded on the bucket.Each supporting leg surrounds a ventilation duct by two steel plates, is equivalent to arm.Supporting leg is designed to the bracket shape, and structure is firm, and supporting capacity is strong, is used to bear the weight of material on the blast cap.Blast cap, supporting leg and Sheng ash bucket are made by heat-resisting steel sheet and plate.Burned material falls within bucket from the endless belt between blast cap and the kiln wall, is discharged by the vibrations discharging machine through metallic hose.Material in the microscler vibrations discharging machine can prevent that the interior gas of kiln from escaping, and promptly plays " expecting envelope " effect, and metallic hose can a damping and an adjusting pipe expansion contraction.The similar dark storehouse of circle of calcining vertical kiln facts have proved, when material [not being to discharge from the center] when dark storehouse lower annular band is discharged, charge level decline is uniform in the storehouse in.So above-mentioned discharge system discharging is uniformly, so material calcining also is uniform in the kiln.
Material adds from charging opening 7, and wind is sent into bustle pipe 1 from gas blower, enters blast cap 3 by arm [supporting leg] 2, and a plurality of air outlets from blast cap evenly enter in the kiln.The material that calcining is good falls into Sheng ash bucket 4 from the belt band between blast cap 3 and the kiln wall, discharges through metallic hose 5 and vibrations discharging machine 6.Waste gas discharges from chimney 9 through the flue 8 that goes in ring.When using gas fuel, coal gas and combustion air are chewed 10 from burning and are entered the kiln internal combustion.When spent air temperture is high, reclaim waste gas residual heat by interchanger 11, also can improve temperature of combustion with fuel saving.The utility model can use solid fuel, as raw coal, lump coal, coke etc.; But also using gas fuel is as blast furnace gas, coke-oven gas, producer gas, mixed gas etc.
In sum, it is reasonable to the utlity model has technology, and equipment is simple, and reduced investment operates reliable advantage.
