Description
Technical field
The utility model relates to a kind of automatic air flow control valve, relates in particular to a kind of for the automatic air flow control valve on cement industry Coolers.
Background technique
Cement industry Coolers is to the air compartment air feed that is positioned at grate plate bottom by blower fan to the cooling of grog, cooling air is through grate plate and grog, by the heat exchange of cooling air and hot grog, grog is carried out coolingly, the clinker temperature of finally using Coolers drops to desirable temperature range.The cooling object of clinker is in order to keep the stable of clinker chemical characteristics, to prevent backward reaction, utilizing to greatest extent waste heat with energy saving.But at present in the running of Coolers, ubiquitous problem is: by rotary kiln, drop to the thickness of feed layer of the clinker in grate plate and the distribution of thickness material is inhomogeneous, because of the thin bed of material and coarse granule bed of material region resistance little, cooling air very easily penetrates thinner region and the coarse granule region of clinker layer, cause thick bed of material region and fines layer region cooling air quantity little, grog can not get cooling fully, easily there is Red River phenomenon, make to draw that Coolers clinker temperature is high, clinker strength declines, and affects the life-span of clinker conveyor equipment.Therefore, take which kind of measure to realize the uniform decrease in temperature of clinker cooling and reach desirable drop temperature, improve the working efficiency of Coolers, become the Important Problems of cement industry.
Model utility content
For above problem the utility model, provide a kind of automatic adjusting air flow rate adjustment valve that can realize the uniform decrease in temperature of clinker.
In order to overcome the above problems the utility model, provide a kind of automatic air flow control valve, it is characterized in that: comprise fixed valve plate, moving valve plate, blade, transmission shaft, spring, regulating ring, housing and fixed support.
Described blade and moving valve plate are fixed together by transmission shaft, and blade is below moving valve plate;
Described fixed valve plate is positioned at moving valve plate top, and fixed support is positioned at blade below, and is individually fixed on housing; Fixed valve plate and fixed support and moving valve plate, blade are on same axle;
Described fixed valve plate is provided with at least one fixed valve plate air door; Moving valve plate is provided with at least one moving valve plate air door;
One end of described spring is fixed on and is arranged on support bracket fastened regulating ring, and the other end is connected with blade.
Described regulating ring is arranged on fixed support by lock screw.
Described regulating ring is also provided with adjusting screw.
Described automatic air flow control valve acts on the effect that active force on blade has overcome spring force while utilizing air-flow to pass modulating valve, and drive vane is rotated, drive moving valve plate synchronously to rotate simultaneously, moving valve plate rotates the relative position of itself and fixed valve plate is changed, thereby throttle opening is changed, thereby changed the throughput by modulating valve.
This modulating valve provides coarse adjustment and two kinds of patterns of fine tuning to the pretightening force of spring, so that this modulating valve quick adjustment is to adapt to different working condition requirements; By unclamping lock screw, rotate regulating ring and utilize adjusting screw to locate the pretightening force of fine tuning spring; By pulling down lock screw, the rotation regulating ring of (90o multiple) utilize adjusting screw to locate the pretightening force of coarse adjustment spring on a large scale.
Useful effect:
Of the present utility model simple in structure, cheap, realize the uniform decrease in temperature of clinker cooling and reach desirable drop temperature, improve the working efficiency of Coolers, extend the working life of clinker conveyor equipment.Theory of the present utility model has the value of the application of expanding simultaneously, not only can be applied to this project, also can directly extend to other field, expands and enriches, and has certain marketing prospect.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of angle 1 of the present utility model.
Fig. 2 is the schematic diagram of angle 2 of the present utility model.
Fig. 3 is partial enlarged drawing of the present utility model.
In Fig. 1, Fig. 2 and Fig. 3: 1-fixed valve plate; 2-moving valve plate; 3-blade; 4-transmission shaft; 5-spring; 6-regulating ring; 7-lock screw; 8-adjusting screw; 9-housing; 10-fixed support; 1-1-fixed valve plate air door; 2-1-movable valve air door.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, Figure 2 and Figure 3, a kind of automatic air flow control valve, comprises fixed valve plate 1, moving valve plate 2, blade 3, transmission shaft 4, spring 5, regulating ring 6, housing 9 and fixed support 10;
Described blade 3 is fixed together by transmission shaft 4 with moving valve plate 2, and blade 3 is below moving valve plate 2;
Described fixed valve plate 1 is positioned at moving valve plate 2 tops, and fixed support 10 is positioned at blade 3 belows, and is individually fixed on housing 9; Fixed valve plate 1 and fixed support 10 and moving valve plate 2, blade 3 are on same axle;
Described fixed valve plate 1 is provided with at least one fixed valve plate air door 1-1; Moving valve plate is provided with at least one moving valve plate air door 2-1;
One end of described spring 5 is fixed on the regulating ring 6 that is arranged on fixed support 10, and the other end is connected with blade 3.
Described regulating ring 6 is arranged on fixed support 10 by lock screw 7.
Described regulating ring 6 is also provided with adjusting screw 8.
Described automatic air flow control valve acts on the effect that active force on blade 3 has overcome spring force while utilizing air-flow to pass modulating valve, and drive vane 3 is rotated, drive moving valve plate 2 synchronously to rotate simultaneously, moving valve plate 2 rotates the relative position of moving valve plate air door 1-1 and fixed valve plate air door 2-1 is changed, thereby throttle opening is changed, thereby changed the throughput by modulating valve;
Concrete, original state is that fixed valve plate air door 1-1 and moving valve plate air door 2-1 are overlapping, when wind speed increases, moving valve plate 2 rotation angles become large, make the dislocation angle of moving valve plate air door 2-1 and fixed valve plate air door 1-1 become large, air door is turned down, thereby the air quantity passing through reduces; Otherwise when wind speed reduces, moving valve plate 2 rotation angles diminish, the dislocation angle of moving valve plate air door 2-1 and fixed valve plate air door 1-1 is diminished, air door is opened, thereby increases by air quantity, this modulating valve is with this, to realize the object of balance air feed.
This modulating valve provides coarse adjustment and two kinds of patterns of fine tuning to the pretightening force of spring 5, so that this modulating valve quick adjustment is to adapt to different working condition requirements; By unclamping lock screw 7, rotate regulating ring and utilize adjusting screw 8 to locate the pretightening force of fine tuning spring; By pulling down lock screw 7, the rotation regulating ring of (90o multiple) utilize adjusting screw 8 to locate the pretightening force of coarse adjustment spring 5 on a large scale.
The foregoing is only preferred embodiment of the present utility model, be not restricted to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
