Description
Technical field
The present invention relates to limekiln technical field, more particularly to a kind of limekiln air feed system.
Background technology
Limekiln is in calcination process, and air volume and uniformity coefficient directly influence the life of calcine, mistake in kiln
Burning rate, is the key for determining lime production and quality, inclined kiln phenomenon occurs if air feed is uneven, the big place of wind occurred
Burn, raw burn occurs in the small place of wind, so as to cause the unstable and lime quality low of lime production.
Common limekiln air feed system is all that wind turbine is passed directly into kiln by air supply line, has one in kiln easily
Tower blast cap is connected with air supply line, this blast cap primarily serves the effect for preventing lime from entering air supply line, such air feed dress
Put simple in structure, do not account for after wind is directly entered pipeline, since wind pressure is big and factor, the wind such as the change of air supply line angle are met
What will be become in air supply line after to the resistance of ducting is uneven, does not account for generation resistance after wind runs into material in kiln and is sent out
Raw air-flow change, can cause air quantity few on the top close to blast cap, center air quantity is small, and air feed is uneven, this air supply mode
The further deterioration that air supply line causes air feed situation is easily blocked after long-term production, overcome there is an urgent need for a kind of limekiln air feed system on
State drawback.
The content of the invention
The present invention overcomes the drawbacks of traditional air feed system, there is provided a kind of uniform limekiln air feed system of air feed.
In order to achieve the above object, the present invention is achieved by the following technical solutions：
The present invention provides a kind of limekiln air feed system, including exhaust fan, air supply line, air collecting box, the exhaust fan and air feed
Pipeline is fixedly connected, and the air collecting box is circular ring shape, and air collecting box is to be fixedly connected with air supply line, the ring-shaped inner wall of air collecting box
On offer three air feed branch pipes, the angle between three air feed branch pipes is 120 °, the other end of three air feed branch pipes
Intersection is provided with blast cap.
Further, the blast cap is multilayer with diameter pyramidal structure, and every layer of blast cap uniformly distributed weekly has multiple
Air supply hole, every layer of blast cap uniformly distributed weekly have multiple air outlets.
Further, the blast cap is 10 layers of same diameter pyramidal structure.
Further, it is laid with ash-pit at the top of the blast cap, the lower part of blast cap, which is laid with, draws ash pipe.
Compared with prior art, the beneficial effects of the present invention are：
Air collecting box described in a kind of limekiln air feed system of the present invention is circular ring shape, can make to be pumped into air supply line through exhaust fan
Air enter air collecting box after wind pressure diminish, make wind speed gentle, ensure uniformity of the wind in air collecting box, then by three into 120
Spend equally distributed air feed branch pipe to be equably sent into blast cap, three wind converge in blast cap, into after blast cap inner cavity, then by wind
Every layer of air supply hole uniformly distributed weekly on cap wall uniformly supplies wind in kiln, since the multilayer of blast cap is the same as diameter turriform
Structure, air supply hole divides multilayer and direction is drawn obliquely downward, makes the wind that is obtained in kiln visibly homogeneous；Divided on the outside air feed of blast cap
Multilayer air outlet, uniformly distributed weekly due to air outlet and every layer, every layer of wind is all confessed obliquely, thus wind
Blown by returning of first oliquely downward drawing near upwards again of each layer of blast cap, undermost wind blows to the outermost of cooling zone by directly returning
Enclose, the wind on upper strata is successively close to center, therefore the wind that the blast cap is supplied, and air feed, energy can be just uniformly distributed from cooling zone bottom
Meet the optimal air feed requirement of production technology；Lay ash-pit at the top of blast cap, lower part, which is laid, draws ash pipe, due to drawing in ash pipe
The powder ash that suction function makes to be pressed on blast cap is easy to fall into ash-pit and collect in draw in ash pipe, is then expelled directly out, this is just reduced
Finished product ash is blown into the powder ash quantity of cooling zone in kiln when pass through blast cap, the grey wind path that blocks of powder is preferably minimized.

Embodiment 1
A kind of limekiln air feed system of the present invention, as shown in Figure 1 and 2, including exhaust fan, air supply line 4, air collecting box 3, the pumping
Wind turbine is fixedly connected with air supply line 4, and the air collecting box 3 is circular ring shape, and air collecting box 3, to be fixedly connected, collects wind with air supply line 4
Offer three air feed branch pipes 1 in the ring-shaped inner wall of case 3, the angle between three air feed branch pipes 1 is 120 °, three
The other end intersection of air feed branch pipe 1 is provided with blast cap 2, and blast cap 2 is multilayer with diameter pyramidal structure, every layer of blast cap 2 every
Week is uniformly distributed multiple air supply holes, and every layer of blast cap 2 uniformly distributed weekly has multiple air outlets；The blast cap 2 is 10 layers
Same diameter pyramidal structure；The top of the blast cap 2 is laid with ash-pit 5, and the lower part of blast cap, which is laid with, draws the pipe of ash 6.
Air enters the air collecting box 3 of circular ring shape through air supply line 4 after being extracted out by exhaust fan, wind is depressurized by air collecting box 3, made
Wind pressure diminishes, wind speed is gentle, uniformly after again by three into 120 degree of equally distributed air feed branch pipes 1, three air feed branch pipes 1
Interior wind facies interaction just enters in blast cap 2 after converging, and 2 every layer of blast cap is designed with weekly equally distributed multiple air supply holes,
Wind is evenly distributed in surrounding, the uniform air outlet of multilayer is divided on 2 outside air feed of blast cap, every layer of wind is all to confess obliquely
, therefore, wind is returned and blown by what 2 each layer of blast cap first oliquely downward drew near upwards again, and undermost wind will directly be returned and blown to
The outermost of cooling zone, successively close to center, what what the top of blast cap 2 was laid fall ash-pit 5 and lower part were laid draws ash pipe for the wind on upper strata
6, the powder ash being pressed in due to drawing the suction function in ash pipe 6 to make on blast cap 2 is easy to fall into ash-pit 5 and collect in draw in ash pipe 6,
Then it is expelled directly out, reduces the powder ash quantity that cooling zone in kiln is blown into when finished product ash passes through blast cap 2.
