Abstract
An explosion door with a double-open structure is arranged on a top of a silo and the door is characterized by comprising (1) a left door, (2) an exhaust pipe, (3) a support beam, (4) a right door, (5) positioning rods, (6) a cotter pin ,(7) a crossette, (8) door pivots and (9) a support. The exhaust pipe (2) is arranged on the top of the silo; the support (9) is welded on two sides of the exhaust pipe (2); the left door (1) and right door (4) are located on the top of the exhaust pipe (2); the door pivot 8 passes through the crossette (7) and the support (9); the cotter pin (6) prevents the door pivots (8) from falling off; the support beam 3 is located on the joint of the left door (1) and the right door (4) and the combination of the above performs a function of supporting and sealing; and the positioning rods (5) are welded respectively on external edges of the left door (1) and the right door (4). The explosion door with a double-open structure is advantageous in that when shock wave is generated by an explosion in the silo, the left door (1) and the right door (4) open simultaneously along the door pivots 8; combustible gas can be expelled in a short time; and when the door is opened to a certain angle, the positioning rods (5) work; and the door can automatically close with the action of gravity, thereby avoiding a situation of incapable reset of the door after the door is open.
Description
Technical field
The utility model relates to the silo explosion proof door, is specifically related to a kind of two explosion proof door of opening.
Background technology
Present silo explosion vent apparatus generally adopts the overall structure explosion proof door, can't close voluntarily after explosion proof door is opened, and needs personnel to close voluntarily; When bigger shock wave appears in the silo implode, can cause explosion proof door to be washed away accident owing to shock wave can't discharge at short notice, cause great potential safety hazard.Therefore be necessary to invent a kind of silo explosion proof door that can open at short notice and can close voluntarily.
Summary of the invention
The purpose of this utility model is to overcome the silo explosion proof door and can not opens the silo explosion proof door that can not close voluntarily at short notice.
The purpose of this utility model is achieved through the following technical solutions:
A kind of double door explosion proof door is positioned at the silo top, it is characterized in that: by 1. left-hand doors, and 2. stack, 3. brace summer, 4. right door, 5. gag lever post, 6. cottor pin, 7. crossette, 8. door-hinge, 9. support is formed.Stack 2 is installed in the silo top, and support 9 is welded on the both sides of stack 2; Left-hand door 1 and right door 4 are positioned at stack 2 tops; Door-hinge 8 passes crossette 7 and support 9; Cottor pin 6 prevents that door-hinge 8 from coming off; Brace summer 3 is positioned at left-hand door 1 and right door 4 interfaces, plays a part to support and sealing; Gag lever post 5 is welded on the outside of left-hand door 1 and right door 4.
The utility model has the advantages that: structure of the present utility model can be that left-hand door 1 is respectively opened along door-hinge 8 simultaneously with right door 4 when the silo implode produces shock wave, fuel gas is discharged at short notice, gag lever post 5 works when door is opened to certain angle, an effect of dependence gravity is closed voluntarily, avoided door to open the irreducible situation in back.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model double door explosion proof door.
Fig. 2 is the vertical view of the utility model double door explosion proof door.
Among the figure: 1. left-hand door, 2. stack, 3. brace summer, 4. right door, 5. gag lever post, 6. cottor pin, 7. crossette, 8. door-hinge, 9. support.
The specific embodiment
As shown in the figure: a kind of double door explosion proof door is characterized in that: stack 2 is installed in the silo top, and support 9 is welded on the both sides of stack 2; Left-hand door 1 and right door 4 are positioned at stack 2 tops; Door-hinge 8 passes crossette 7 and support 9; Cottor pin 6 prevents that door-hinge 8 from coming off; Brace summer 3 is positioned at left-hand door 1 and right door 4 interfaces, plays a part to support and sealing; Gag lever post 5 is welded on the outside of left-hand door 1 and right door 4.Left-hand door 1 and right door 4 are respectively opened simultaneously along door-hinge 8 when the silo implode produces shock wave, fuel gas is discharged at short notice, gag lever post 5 works when door is opened to certain angle, and an effect of dependence gravity is closed voluntarily, has avoided door to open the irreducible situation in back.
