Description
Technical Field
The utility model relates to a boiler bottom shutoff door with adjustable sealing depth, which can be widely applied to a wet slag removal system of a boiler in the fields of electric power and chemical industry.
Background
The existing boiler bottom shut-off door is opened when in operation, and because the sealing depth cannot be adjusted, the boiler shut-off door has the air leakage risk, so that the combustion efficiency of the boiler is influenced, and the combustion efficiency of the boiler is low.
Disclosure of Invention
The utility model aims to provide the boiler bottom shutoff door with adjustable sealing depth, which has the advantages of adjustable sealing depth, reliable sealing, reduced air leakage risk and high boiler combustion efficiency.
In order to achieve the above purpose, the boiler bottom shutdown door with adjustable sealing depth comprises a main frame, two hook-type driving rods symmetrically arranged on the main frame and capable of rotating around a hinge shaft through a first hinge shaft, a cylinder body, two driving cylinders arranged on the main frame and capable of rotating around the hinge shaft through a second hinge shaft, a piston rod connected with the hook-type driving rods through a third hinge shaft, two door frames arranged at the tail ends of the hook-type driving rods and provided with grooves through a fourth hinge shaft, two door leaves fixedly arranged on the inner side surfaces of the door frames, an adjusting plate with a connecting sleeve, a nut for fastening the adjusting bolt together with the adjusting plate on the door frames through the connecting sleeve of the adjusting plate and the adjusting bolt arranged in the grooves of the door frames, and a balancing weight arranged on the outer side surface of the lower end of the adjusting door.
The utility model relates to a boiler bottom shutoff door with adjustable sealing depth, which has the following working principle: when the coal-fired boiler works normally, the two door leaves are in a normal opening state; when the next-stage conveying equipment needs to be maintained, the two door leaves are in a closed state.
According to the boiler bottom shutoff door with the adjustable sealing depth, the adjusting bolt can drive the adjusting plate to slide in the groove of the door frame, the upper and lower heights of the adjusting plate are adjusted, and after the height position of the adjusting plate is determined, the adjusting plate is fixed on the door frame through the adjusting bolt and the nut to be positioned. Thus, the sealing depth adjustment of the adjusting plate is completed. Therefore, the sealing depth is adjustable, the sealing is reliable, the risk of air leakage is reduced, the combustion reliability of the hearth is improved, and the combustion efficiency of the boiler is high.
According to the boiler bottom shutoff door with the adjustable sealing depth, after the boiler shutoff door is closed, the position of the adjusting plate is automatically adjusted under the action of gravity, and the adjusting plate is not interfered with other parts. When the boiler shut-off door is opened, the depth of the adjusting plate can be adjusted according to actual needs.
In conclusion, the boiler bottom shutoff door with the adjustable sealing depth is adjustable, the sealing depth is reliable, the risk of air leakage is reduced, and the combustion efficiency of the boiler is high.
Drawings
The utility model will be further described with reference to the accompanying drawings and examples.
