Business, also needs to recycle while cooling high-temperature clinker a large amount of heat contents of clinker carrying, and the quality of runnability directly affects
To the yield and quality of clinker, the running rate of firing system heat consumption and whole production line.
Clinker in cement rotary kiln, which unloads, to be fallen in the grate of grate-cooler, and clinker particle size distribution range itself is larger, shape
Shape is complicated, and under the influence of eduction, it is seriously uneven to will lead to clinker thickness and size distribution in grate.Clinker thickness and hole
The wide fluctuations of rate will lead to the greatest differences of clinker layer resistance.On the other hand, current grate-cooler often uses a small amount of wind
The mode of machine, big air compartment air feed certainly will cause the ventilation quantity of part grate plate bigger than normal if not adjusted to the air feed of every piece of grate plate
And the ventilation quantity of other grate plate is smaller, this not only influences the cooling effect and heat recovery rate of clinker, it is also possible in the bed of material
Upper formation " Red River " phenomenon (for part fine particle since wind-engaging is less, mobility is preferable, flows in grate-cooler two sides).Therefore,
It is necessary to the ventilation quantities to every piece of grate plate to be self-regulated, and carry out resistance balance using regulating valve, the flow to guarantee air-flow is equal
Weighing apparatus is stablized, and does not change with the variation of materialbeds comminution.
The advantages of current existing grate-cooler flow valve has the types such as gravity type and elastic force type, gravity type flow valve is
Maintenance is few, is influenced small, mechanically deform possibility is low etc. by dust, but often volume is larger for existing gravity type flow valve, adjusts
Adjusting range is relatively narrow, and clump weight weight is larger, not easy to install.Elastic force type flow valve is volume compared to gravity type flow valve advantage
Smaller, adjustable range is larger, easy for installation etc., but there are problems that spring fatigue loss, and long-time service can gradually fail.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain that this is practical new
Type is not used to limit the utility model.
The utility model provides a kind of gravity type automatic flow control valve, including a quarter cylindrical housings 1, institute
The central axis for stating cylindrical housings 1 is horizontally disposed so that arc surface is the wind surface of valve body；Connect in the upper surface of cylindrical housings 1
It is connected to flange connector 2；The flange connector 2 can be directly connected with the comb box in grate by screw；The flange connects
Fitting 2 is plate；The upper surface of the cylindrical housings 1 and the corresponding position of flange connector 2 are provided with fixed air flow inlet
One 21, the arc surface of cylindrical housings 1 is equipped with the variable airflow entrance 11 opposite with fixed air flow inlet 1, such air-flow
Cylindrical housings 1 and flange connector 2 can be passed through, and enters comb box；The opening shape of variable airflow entrance 11 is according to calculating
Good ventilation quantity is designed；Preferably, the opening width of the variable airflow entrance 11 is from low to high according to certain rule song
Line is gradually reduced；
The valve plate 3 that can be swung along arc surface is equipped in the cylindrical housings 1；One end of the valve plate 3 is equipped with circle
Sleeve 31 is equipped with shaft, the circular sleeve 31 in one end that fixed air flow inlet 1 is parallel to 1 central axis of cylindrical housings
It is socketed with the shaft, such valve plate 3 can be put in cylindrical housings 1 centered on shaft using 3 height of valve plate as radius
It is dynamic；The motion range of valve plate 3, which is subject to, can cover variable airflow entrance 11, and such valve plate 3 can adjust air-flow in swing
Throughput.
Rigid connecting rod 4 is fixed in 3 lower end of valve plate, lower end and the clump weight 5 of connecting rod 4 are fixedly linked, and valve plate 3 exists
It will drive clump weight 5 in swing to move together, realize that the pressure torque of the gravity torque and valve plate 3 of clump weight 5 acts on simultaneously
In shaft.Preferably, 5 weight Q of clump weight is acted in 3~5kg, the weight of clump weight 5 with the length of connecting rod 4 simultaneously, is formed
Downward torque at shaft.Air-flow passes through flow valve from the bottom to top, forms upward pressure poor △ P, △ in 3 upper and lower surface of valve plate
P minimum about 500Pa, the largest of about 3000Pa.
In the cylindrical housings 1 perpendicular on two axial sides, it is provided with fixed air flow inlet 2 12；Described
Fixed air flow inlet 3 22 is also provided on flange connector 2；The fixed air flow inlet 3 22 in the vertical direction with cylinder
Shell 1 is arranged in a staggered manner, and such air-flow directly can enter comb box from fixed air flow inlet 3 22 without cylindrical housings 1.
Working principle:
Based on fluid mechanics principle, the regulating valve of this patent is equivalent to the throttling member that a local resistance can change automatically
Part.On the one hand, when air-flow is by the variable airflow entrance 11 and fixed air flow inlet 1, in the upper and lower end face of valve plate 3
Formation upwards pressure poor △ P, to form the upward torque acted in shaft；On the other hand, it is connected with valve plate 3
Its gravity of clump weight 5 Q can equally act in shaft one downward torque of formation；As shown in figure 5, two power are made simultaneously
With, make valve plate 3 stablize in a certain height and position.Initial stage, when the air-flow that valve body passes through is smaller, 3 two-way pressure of valve plate is poor
△ P is small, and valve plate 3 is located at lowermost end；When air-flow is gradually increased, valve plate 3 is swung up under the promotion of pressure difference △ P, due to
The opening width of the variable airflow entrance 11 is gradually reduced according to certain rule curve from low to high, so valve plate 3 is more upward
It swings, the area of the variable airflow entrance 11 on arc surface more reduces, and air flow rate is constant air velocity increases；Work as valve
When plate 3 swings to the highest point with variable airflow entrance 11, effective air flow inlet area on arc surface is kept to zero, and air-flow passes through
The gap on fixed air flow inlet 2 12, fixed air flow inlet 3 22 and valve plate 3 and 1 periphery of cylindrical housings enters in valve, from
And achieve the purpose that air quantity equalization stable.Passing through the effect of flow valve, it is ensured that the gas flow by each grate plate is equal,
Avoid the phenomenon unbalance because of the air volumematching that materialbeds comminution is different and occurs.
