Abstract

The invention relates to an automatic on-and-off gravity type anti-explosion door, which can be used for a coal storage cylinder protection system in the industries of a thermal power industry, a coal chemical industry, a coal operation station industry and the like, and can be used for preventing from damage caused by secondary combustion and explosion of flammable and explosive gas in a cylinder. The automatic on-and-off gravity type anti-explosion door comprises a base assembly, a cover plate, a hinge, a shock absorption bracket, and a shock absorption spring; the base assembly is connected with the cover plate through the hinge; the shock absorption bracket is welded on the base assembly; and the shock absorption spring is welded at the upper end of the shock absorption bracket. Compared with the gravity type anti-explosion door, the automatic on-and-off gravity type anti-explosion door has the following advantages: 1) the automatic on-and-off gravity type anti-explosion door can be automatically reset in an accurate and timely manner, so as to effectively avoid a situation that the cover plate of the anti-explosion door cannot be reset in time because an opening angle of the cover plate of the anti-explosion door is more than 90 degrees; and 2) the stress of the hinge is reduced, so that the service life of the hinge is prolonged.

Description

Automatic open and close gravity explosion proof door
Technical field
The present invention relates to a kind of automatic open and close gravity explosion proof door.
Background technology
Flammable explosive gas such as the methane in the coal storage silo of industries such as existing thermoelectricity, Coal Chemical Industry, coal running station, carbon monoxide produce and are easier to; Rapid speed, gathering has explosion danger when acquiring a certain degree, in case blast; Can cause very big economic loss to enterprise, even casualties.At this moment then need effectively pressure release of explosion proof door, prevent the subsequent explosion of silo.
Gravity explosion proof door simple in structure, cost is lower, is the first-selection of silo venting of dust explosion.But common gravity explosion proof door is simple base and cover plate, is connected through the hinge.The explosion proof door of this spline structure is easy to because of the silo internal pressure excessive in use, and the angle that causes cover plate to be opened surpasses 90 °, can't in time reset.This explosion proof door is higher to the toughness reguirements of hinge, and long-time use is bigger to the damage of hinge.
Summary of the invention
The objective of the invention is for solving the weak point of above-mentioned prior art, a kind of automatic open and close gravity explosion proof door is provided.
The present invention addresses the above problem the technical scheme that is adopted to be: automatic open and close gravity explosion proof door; Comprise base assembly (1), cover plate (2), hinge (3); Base assembly (1) is connected with cover plate (2) through hinge (3); It is characterized in that on base assembly (1), being welded with shock bracket (4), be welded with damping spring (5) in the upper end of shock bracket (4).
The advantage of patent of the present invention is: 1) automatically reset accurately and timely, effectively avoided the open angle of explosion proof door cover plate to surpass 90 °, the situation that causes in time resetting takes place; 2) it is stressed to slow down hinge, increases the application life of hinge.
Description of drawings
Fig. 1 is structural shape figure of the present invention;
Fig. 2 is a left view of the present invention.
1. base assembly, 2. cover plate, 3. hinge, 4. shock bracket, 5. damping spring.
The specific embodiment
Automatic open and close gravity explosion proof door can be installed in the top of coal storage silo, and the quantity of installation and size are confirmed according to the size of silo.The cover plate of explosion proof door (2) can be around hinge (3) upset, and maximum opening receives shock bracket (4) and damping spring (5) restriction.When the pressure in the silo was raised to certain value, gas was washed the cover plate (2) of explosion proof door open in the silo, and when the pressure in the silo dropped to certain value, the cover plate of explosion proof door (2) closed under the effect of gravity automatically.In cover plate (2) opening procedure of explosion proof door; Can be limited to certain angle place by damping spring (5) after running into damping spring (5); Avoided cover plate (2) to such an extent as to upset surpasses 90 ° of situations generations that can't reset; After pressure in silo drops to certain limit value, cover plate (2) auto-closing under action of gravity.

Claims (1)

1. automatic open and close gravity explosion proof door; Comprise base assembly (1), cover plate (2), hinge (3); Base assembly (1) is connected with cover plate (2) through hinge (3); It is characterized in that on base assembly (1), being welded with shock bracket (4), be welded with damping spring (5) in the upper end of shock bracket (4).
