Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of double horn mouth formula shaft furnace kiln bottom discharge bucket structure described in the utility model is set to complete negative
The cooling pars infrasegmentalis of the shaft furnace of press operation；Slot 1, peripheral groove 3, stiffener plate 4 and straight pipe 6 are enclosed including interior, inside encloses slot 1 and periphery
It is fixedly connected between slot 3 by the multiple stiffener plates 4 being uniformly arranged in the circumferential direction；Slot 1 is enclosed in described and peripheral groove 3 all has
Small bell-mouth structure of air under big, between the two there is uniform gap to form cooling air channel 7；The top for inside enclosing slot 1 is higher than
The top of peripheral groove 3, so that top annular air inlet is formed on the top in cooling air channel 7；The bottom of slot 1 is inside enclosed higher than outer
The bottom of slot 3 is enclosed, so that base circle air inlet is formed on the bottom in cooling air channel 7；The bottom of peripheral groove 3 and straight pipe
6 connections.
The top that slot 1 is enclosed in described sets inlet flange 2, is bolted with the outlet(discharge) flange of shaft furnace bottom coohng section.
The peripheral groove 3 is circumferentially arranged with multiple hand holes 5.
The straight pipe 6 with shaft furnace discharging device entrance for connecting.
The horizontal cross sectional geometry that slot 1 and peripheral groove 3 are enclosed in described is rectangle or circle.
As shown in figure 3, a kind of working method of double horn mouth formula shaft furnace kiln bottom discharge bucket structure described in the utility model
As follows: cooling air enters cooling air channel 7 by top annular air inlet, then enters shaft furnace from base circle air inlet
Cooling section bottom from bottom to top cools down material 8 in kiln；The material 8 calcined passes through shaft furnace after cooling section is cooling
Discharging device discharging；Multiple hand holes 5 that peripheral groove 3 is circumferentially arranged, for carrying out block clearing operation in cooling air channel blockage.
Following embodiment is implemented under premised on technical solutions of the utility model, gives detailed embodiment
With specific operating process, but the protection scope of the utility model is not limited to the following embodiments.Side used in following embodiments
Method is conventional method unless otherwise instructed.
[embodiment]
By taking the discharge bucket that cross section is square as an example, previous discharge bucket be single layer structure, the outlet of 4 blocks of coaming plates directly with
Welding at the top of straight pipe distinguishes wide-bore in the middle and lower part of coaming plate, then welds the diameter of several uniform intervals arrangements in tapping
The spacing of identical round bar, round bar is less than material minimum lumpiness, ventilation hole of the gap as material cooling wind.Due to this
Ventilation hole is directly contacted with material, and after producing a period of time, the gap between round bar will be filled by material, and have few portion
Divide material that can be also fallen on other work tops from disposed at air vent, destory the scene production environment；It divulges information and unsmooth causes kiln discharge object
Expect temperature drift, the accident for burning finished belt conveyer caused to occur, reach shaft furnace can not and produce,
As shown in Figure 1-Figure 3, a kind of specific structure of double horn mouth formula shaft furnace kiln bottom discharge bucket structure is such as in the present embodiment
Under: slot 1, which is enclosed, in discharge bucket is made of coaming plate in 4 pieces；The peripheral groove 3 of discharge bucket is made of 4 pieces of peripheral boards, and straight pipe 6 is by 4 pieces
Steel plate composition；It inside encloses and sets 16 pieces of stiffener plates 4 between slot 1 and peripheral groove 3, and be evenly distributed；On 4 faces of discharge bucket respectively
If hand hole 5.
The inlet flange 2 of slot 1 is enclosed in discharge bucket and shaft furnace cooling section end outlet flange is bolted；In 4 pieces
Coaming plate is first welded into up big and down small bell shape, then welds with inlet flange 2.4 pieces of peripheral boards are first welded into up big and down small
Bell shape, then welded with the straight pipe 6 being welded by 4 blocks of steel plates.16 pieces of stiffener plates 4 enclose 1 outside of slot rationally inside
It is distributed and welds, then welded with the inside of peripheral groove 3, since then, discharge bucket completes.
Using discharging bucket structure described in the utility model, cooling air can move smoothly through the entrance of cooled gas path 7
In shaft furnace, it can either guarantee being fully cooled for material 8, and cooling air channel 7 and 8 down going channel of material are non-interference, object
