Description
Technical field
It the utility model is related to a kind of air control valve.
Background technology
At present in the technique of the preparation of clinker, grate-cooler is equipped as the cooling and recuperation of heat of clinker, is had not
The status that can or lack, the cooling effect of clinker is fine or not, directly affects the calorific value of the grain properties of clinker particles and the hot blast of recovery,
Good cooling results, clinker particles crystal grain is thin and microfissure is more, and beneficial to the raising of cement grinding and strength of cement, and calorific value returns
Receipts amount is big, even more the direct embodiment of cost savings.Grate-cooler has evolved to the structure shape of the 5th generation step-by-step movement horizontal beds at present
Formula, the cooling air feed of its grate plate use the form of centralized supply wind, and the allocated air quantity of each grate plate is controlled by flow air control valve.Mesh
The primary structure of preceding flow air control valve is movable funnel-cap type or pendulum clack type, but all exists and react insensitive or actual use effect
The bad situation of fruit, so as to cause the uneven result of the clinker cooling on cooler；Its directly performance be exactly easily occur it is red
River and the phenomenon of material leakage, and the hot blast temperature reclaimed is not easy stabilization.Therefore, can air control valve according to the load above grate plate, spirit
Quick regulation air quantity, largely have influence on the cooling effect of clinker.
The content of the invention
It the utility model is related to a kind of air control valve, solve that the reaction of air control valve is insensitive in the prior art causes clinker cold
Technological deficiency uneven, cooling effect is poor.
To solve the above problems, technical solution adopted in the utility model is：A kind of air control valve, including it is cylinder, multiple
Valve plate and the quantity deflector equal with valve plate, the bottom of cylinder is separated into by the bottom that described deflector is arranged in cylinder
Multiple lower air-guiding aisles, the outer edge of deflector are bonded with cylinder inner surface, the top in described cylinder be provided with quantity with
The hanging plate axle that valve plate is equal, one end and cylinder inner surface are fixed, be rotatably arranged on hanging plate axle at the top of described valve plate and
Valve plate can be spun upside down around hanging plate axle, described valve plate by the upper part of cylinder every in multiple lower air-guiding aisles, under described
The quantity of air-guiding aisle is equal with upper air-guiding aisle, and described deflector is obliquely installed, and the top of deflector is located at hanging plate axle
Underface, the lower end of each upper air-guiding aisle communicate with the top of a lower air-guiding aisle.The housing that the utility model uses, lead to
The wind for entering valve body produces rotation naturally by deflector and the lower air-guiding aisle of cylinder formation, forms the state of eddy flow, Ran Houzai
By the upper air-guiding aisle being made up of valve plate and cylinder being positioned above, valve body uses relatively thin steel plate, is rotatably arranged on extension
In board shaft, itself is in light weight, and also very flexibly, therefore very sensitive to the feedback of wind-force, wind is laggard by air control valve for valve plate revolution
Enter grate plate, if the resistance on grate plate top is small, increased by the wind speed of valve body, then whirlwind acts on the power increase of valve plate, valve plate
Blown afloat and reduce upper air-guiding aisle（That is wind passes through area）, so as to reduce the air quantity passed through, until reaching balance, work as grate plate
After the resistance on top becomes big, reduced by the wind speed of valve body, the power that whirlwind acts on valve plate reduces, and valve plate downwardly turns over, valve body
Draught area increase so as to increase the air quantity passed through, until reach balance, air control valve passes through comb according to wind in the utility model
Drag size during plate, the area that air-guiding aisle wind passes through in adjustment, adjust automatically wind speed, valve plate feed back sensitive, institute to wind speed
Good with the clinker cooling effect on cooler, clinker is not in the phenomenon of Red River and material leakage.
As further improvement of the utility model, in addition to vertical rod, described vertical rod be located at the center of cylinder and
Set along the length direction of cylinder, the inside edge of described deflector and the bottom of vertical rod fix, described hanging plate axle it is another
One end and the top of vertical rod are fixed.On the one hand the utility model facilitates the fixation of deflector and hanging plate axle, separately by setting vertical rod
