Abstract
The utility model discloses a novel gas-sealed air door, which is used for flue gas dust-removal equipment and comprises a sealing board, a support, a lifting rod, and a cylinder. The utility model is characterized in that the sealing board comprises two layers of soft sealing boards and a support board; a sealed cavity body is arranged between the two layers of soft sealing boards and the support, and the sealed cavity body is internally provided with clean gas. By using the elastic deformation characteristic of the soft sealing board, the sealing performance of the air door is improved, and the rigidity of the air door is guaranteed by the rigid support board. The air door adopts the design of the structure of two layers of soft sealing boards; the sealed air is pressed into the cavity body of the two layers of soft sealing boards, thereby guaranteeing the sealing performance of the air door. The air door adopts the mode of pneumatic vertical turn-on, that is, the turn-on of the air door is realized via the cylinder to drive the sealed board to move upward and downward, thereby solving the phenomenon of being unable to turn on normally when the air door is locked on structure design. The air door has simple structure, reasonable design, high sealing performance, and solves the common fault of being unable to turn on normally owing to easy lock of the air door.
Description
Affiliated technical field
The utility model relates to a kind of hermetic seal air door that is used for smoke dust-removing equipment.
Background technology
Smoke dust-removing equipment especially sack cleaner often needs to be provided with by-pass flue and bypass air door, and the leakage of bypass air door is very big to the efficiency of dust collection influence of cleaner.At present, known conventional bypass air door adopts mechanical seal mode or double-deck venetian blind type to add hermetic, because the size of air door is bigger, the sealing of mechanical seal mode is difficult to ensure, the slit is bigger between the blade of double-deck venetian blind type, the sealing that needs is large-minded, and the Yi Fashengyin blade blocks the situation that air door can not normally be opened.
Summary of the invention
In order to overcome the deficiency that existing bypass air door sealing property deficiency, air door can not normally be opened, it is a kind of simple in structure that the utility model provides, the air door of good seal performance.
The technical scheme that its technical problem of solution of the present utility model is adopted is: a kind of novel hermetic seal air door, form by sealing plate, bearing, lifting arm, cylinder, it is characterized in that: sealing plate is made up of two sheets of flexible sealing plate and gripper shoe, form seal chamber between two sheets of flexible sealing plate and the bearing, clean gas is arranged in the seal chamber.
Flexible sealing plate, gripper shoe and lifting arm all adopt bolted on connection, and the junction of flexible sealing plate and gripper shoe scribbles fluid sealant.
The beneficial effects of the utility model are: the sealing plate of air door is made up of sheet metal flexible sealing plate of making and the rigid support plate made from steel plate.Utilize the characteristic of the strain of flexible sealing plate, strengthen the sealing of air door, utilize rigid support plate to guarantee the rigidity that air door itself is required.Air door adopts the design of two sheets of flexible sealing plate structure, indentation sealing air between the seal chamber in the two sheets of flexible sealing plate, thereby the sealing of assurance air door.Air door adopts the pneumatic vertical opening ways, promptly drive moving up and down of sealing plate by cylinder and realize the unlatching of air door, has solved on structural design that air door is stuck and the phenomenon that can not normally open.Air door structure is simple, reasonable in design, the sealing height, and solve the easily past common fault that can not normally open that causes of card of air door.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is that master of the present utility model looks schematic diagram.
Among the figure: 1. flexible sealing plate, 2. rigid support plate, 3. bearing, 4. lifting arm, 5. sealing air inlet, 6. cylinder, 7. seal chamber.
The specific embodiment
In the drawings, novel hermetic seal air door, form by sealing plate, bearing (3), lifting arm (4), cylinder (6), sealing plate is made up of two sheets of flexible sealing plate (1) and gripper shoe (2), form seal chamber (7) between two sheets of flexible sealing plate (1) and the bearing (3), seal chamber has clean gas in (7).Flexible sealing plate (1), rigid support plate (2) all adopt bolted on connection with lifting arm (4), coat fluid sealant in the flexible sealing plate (1) and the junction of rigid support plate (2), prevent seepage.In working order down, cylinder (6) forces in the flexible sealing plate (1) that rigid support plate (2) goes up also last transmission by lifting arm (4), flexible sealing plate (1) is pressed on the bearing and certain deformation takes place, and guarantees tight contact of flexible sealing plate (1) and bearing (3).Be pressed into clean sealing gas at seal chamber (7) simultaneously, be higher than the absolute pressure of air door pressure at both sides upper side, just can guarantee the sealing of air door as long as guarantee the absolute pressure of the interior gas of seal chamber (7).
Claims (2)
1. a novel hermetic seal air door is made up of sealing plate, bearing, lifting arm, cylinder, and it is characterized in that: sealing plate is made up of two sheets of flexible sealing plate and gripper shoe, forms seal chamber between two sheets of flexible sealing plate and the bearing, and clean gas is arranged in the seal chamber.
2. according to claims 1 described a kind of hermetic seal air door, it is characterized in that: flexible sealing plate, gripper shoe and lifting arm all adopt bolted on connection, and the junction of flexible sealing plate and gripper shoe scribbles fluid sealant.
