Description
Technical field
The utility model relates to boiler, particularly a kind of convenient boiler wind pushing box of transferring wind.
Background technology
The wind that existing boiler wind pushing box has directly blasts the boiler air compartment by each air outlet after the wind pushing box air inlet blasts, this wind pushing box blasts the blast of air compartment and plate-turning door or the arm-tie gate control that air quantity is positioned at the wind pushing box air inlet, because plate-turning door or arm-tie door turn-off the effect imprecision, be difficult to control when particularly needing little air quantity, be not easy to transfer wind, uncontrollable boiler reaches best combustion efficiency.Though the boiler that has adopts plate or the turnover panel be located on the wind pushing box air outlet to transfer wind, regulate the combustion efficiency that the air quantity size that blasts air compartment changes boiler thereby can just omit, can not realize self-locking but still exist, producing the easy loosening air quantity that causes of vibrations back card/back board or turnover panel in the wind pushing box air-supply process changes, transfer wind stability poor, air quantity is regulated insensitive, and shortcomings such as poor controllability, result of use are also not ideal enough.
Summary of the invention
The purpose of this utility model provide a kind of air quantity that blasts air compartment evenly, be convenient to transfer wind, can realize self-locking, the wind pushing box casing shaken the back air output and can not changed, transfer that wind stability is good, blast, air quantity is regulated, and self-locking sensitive, that controllability is good, easy to use rotates air register boiler wind pushing box.
Technical solution of the present utility model is: it comprises the wind pushing box casing, the wind pushing box casing is provided with an air inlet and several air outlets, be separately installed with the rotation air register on each air outlet, each rotates on the rotatable lamella of air register and is fixed with the transmission fork, the operating-controlling mechanism that is made of intermeshing worm gear and worm screw is installed on the wind pushing box casing, the end of worm screw is provided with and is positioned at the outer crank of wind pushing box casing, one end of worm gear is fixed with and is positioned at the outer pointer of wind pushing box casing, also be fixed with the swing arm that is connected with the transmission fork of each rotation air register by the push-and-pull connecting rod on the worm gear, one end of push-and-pull connecting rod and the end of worm gear swing arm are hinged, and each end that rotates air register transmission fork is hinged with the push-and-pull connecting rod respectively.
Technique effect of the present utility model is: the air quantity that this boiler wind pushing box blasts air compartment is even, and wind can grow out of nothing and expand from small to large, is convenient to transfer wind, can realize self-locking, the wind pushing box casing is shaken the back air output can not changed, and transfers wind stability good, air quantity is regulated sensitive, and controllability is good, and result of use is good.
The adjustment of worm and gear operating-controlling mechanism is stable flexibly, action is trickle, and controllability is strong.
The use of this accent wind mechanism has improved the means that grate firing boiler is adjusted combustion conditions, no matter from the preheating dry distillation area to the primary zone, burning-out zone, what are adjustable very convenient with wind, have guaranteed the needed air quantity condition of combustion conditions, can effectively improve burning quality.Electronicly just can realize automatic control manually becoming, be the boiler energy-saving consumption reduction, improves the thermal efficiency and set up the basis.
Description of drawings
Accompanying drawing is the utility model embodiment three-dimensional cutaway view.
The specific embodiment
As shown in drawings, it comprises wind pushing box casing 1, wind pushing box casing 1 is provided with an air inlet 11 and several air outlets 12, be separately installed with rotation air register 2 on each air outlet 12, each rotates on the rotatable lamella 21 of air register 2 and is fixed with transmission fork 22, the operating-controlling mechanism that is made of intermeshing worm gear 3 and worm screw 4 is installed on the wind pushing box casing 1, the end of worm screw 4 is provided with the crank 41 that is positioned at outside the wind pushing box casing 1, one end of worm gear 3 is fixed with the pointer 31 that is positioned at outside the wind pushing box casing 1, also be fixed with the swing arm 32 that is connected with the transmission fork 22 of each rotation air register 2 by push-and-pull connecting rod 5 on the worm gear 3, one end of push-and-pull connecting rod 5 and the end of worm gear swing arm 32 are hinged, and each end that rotates air register transmission fork 22 is hinged with push-and-pull connecting rod 5 respectively.
Also can not establish pointer 31 on the worm gear 3, and transparent form is set on wind pushing box casing 1, can reach equally and observe the purpose that rotation air register 2 opens and closes situation.
By positive hour hands, thereby the crank 41 of counterclockwise hand worm screw 4 can be controlled worm screw 4 and rotate 3 rotations of drive worm gear, worm gear 3 drives swing arm 32 reciprocally swingings, transmission fork 22 reciprocally swingings of air register 2 are respectively rotated in swing arm 32 by 5 push-and-pulls of push-and-pull connecting rod, thereby rotating, the rotatable lamella 21 of transmission fork 22 swing driven rotary air registers 2 can control the purpose that rotation air register 2 apertures size reaches accent wind, the big I of rotation air register 2 apertures realizes by the deflection angle of observing pointer 31, the effect that has reverse self-locking owing to the operating-controlling mechanism that constitutes by worm gear 3 and worm screw 4, can not cause worm gear 3 to rotate after wind pushing box casing 1 is shaken, both can reach self-locking and transfer wind, accurately control the purpose of air quantity.If crank 41 is changed into the motor transmission with regard to the condition that provides the foundation for the automation of accent wind.
