Abstract
The utility model provides a lime kiln secondary ventilation apparatus for industrial furnaces. The structure of the lime kiln secondary ventilation apparatus is that the middle of a kiln body (1) is provided with a plurality of ventilating holes (3) which are uniformly distributed from a kiln wall to the inner part of the kiln body, and a ventilating pipe (5) which is corresponding to the ventilating holes and the end part is provided with a flange cover (6); the ventilating pipe (5) is connected with an annular ventilating pipeline (2) arranged outside the kiln body (1) via a valve (4). With the advantages of simple structure, convenient installation and operation, adjustable air quantity, etc., the utility model can efficiently enhance the quality and yield of products, and the combination property of kilns.
Description
The utility model relates to a kind of ventilation plant, particularly relates to a kind of ventilation plant of Industrial Stoves.
Existing limestone kiln is adopted the bottom natural ventilation usually or is carried out force ventilated air supply mode with blower fan and promptly once ventilates.This draft type is big for internal diameter, the big kiln of exerting oneself is easy to generate " fire partially " and " dross " phenomenon, and can't adjusts and handle in the kiln in calcination process.Directly influence the quality of product and reduce yield rate, may cause structure deteriorate when serious and stop production and keep in repair.
The purpose of this utility model is to provide a kind of kiln to avoid producing " fire partially ", " dross " and structure deteriorate phenomenon in calcination process, and the limestone kiln twice aeration device with yield rate of improving the quality of products.
The purpose of this utility model realizes in the following manner: this utility model comprises valve and blind flange, be provided with the vent-pipe that equally distributed some ventilation holes, and end corresponding with ventilation hole are provided with blind flange at kiln body middle part along the kiln wall in kiln, each vent-pipe is arranged on the external loop vent pipeline of kiln and is connected by a valve is same.
The utlity model has advantages such as simple in structure, easy to install, that air quantity can be regulated, especially after being provided with ventilation hole, multiple spot can controlling and regulate the calcining temperature at each position, transverse section in the kiln effectively, thereby further improve the design synthesis performance in limestone kiln, the output of product and quality are all increased significantly.
Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail:
Fig. 1 is the structural representation of limestone kiln twice aeration device.
By limestone kiln twice aeration device shown in Figure 1, be that middle part (being waist) at kiln body 1 is provided with equally distributed several ventilation holes 3 along the kiln wall in kiln, fix the vent-pipe 5 that an end is provided with blind flange 6 on the ventilation hole 3 respectively, this vent-pipe 5 can be vertical with the kiln wall, also can be a pitch angle and be provided with.Connect a valve 4 on each vent-pipe 5, be connected by the set loop vent pipeline 2 in valve 4 and kiln body 1 outside again.Introduce wind regime from the pipe connecting 7 of loop vent pipeline 2 one ends, this wind regime can be obtained by a shared blower fan of ventilation system.
During work,, then open this side valve door 4, strengthen its ventilation when finding that from temperature instrumentation certain side temperature is on the low side in the kiln, and the corresponding air output that reduces other ventilation hole 3, till kiln temperature balance.And then each valve 4 is transferred to the appropriate location, add large population's ventilation and get final product.
Claims (1)
1, a kind of limestone kiln twice aeration device, comprise valve (4) and blind flange (6), it is characterized in that at kiln body (1) middle part being provided with the vent-pipe (5) that equally distributed some ventilation holes (3), and end corresponding with ventilation hole (3) are provided with blind flange (6) along the kiln wall in kiln, each vent-pipe (5) is connected with being arranged on kiln body (1) loop vent pipeline (2) outward by a valve (4).
