Abstract
The utility model belongs to an anti-explosion pressure relief device for a dust collection container and a dust remover, in particular to the anti-explosion pressure relief device. An interface pipe is arranged on a through opening of the dust remover, an anti-explosion valve is hinged to an upper opening of the interface pipe through a hinging seat, a sealing pad is arranged under the anti-explosion valve and is matched with the upper opening of the interface pipe, and a hook is hinged to the free end of the anti-explosion valve and is matched with a stop block fixedly connected onto the interface pipe, so the upper opening of the interface pipe is sealed through the anti-explosion valve, an electromagnetic micro switch is arranged on the interface pipe arranged at the lower part of the stop block, and an armature of the electromagnetic micro switch is matched with the side end surface of a hook head of the hook. The anti-explosion pressure relief device has the advantages that the structure is simple and practical, the manufacturing cost is low, when the pressure in the dust collecting container and the dust recover reaches the rated pressure, the automatic control active pressure relief can be realized, the pressure relief action is sensitive, the performance is safe and reliable, and the equipment damage cannot be caused.
Description
Technical field
The utility model belongs to the explosion-proof decompression device of dust collection container and deduster, particularly a kind of explosion-proof decompression device.
Background technique
The device of existing dust collection container and deduster explosion-proof relief generally takes mechanical type explosion proof door or explosion-proof valve to carry out passive pressure release, and the way of the explosion pressure of releasing is carried out pressure release, to reach the safety of protection powder processing apparatus.According to the feature of dust explosion: 1) repeatedly blast is the maximum feature of dust explosion; (2) the required minimum ignition energy of dust explosion is higher, generally more than tens millijoules; (3) compared with combustible gas explosion, dust explosion pressure rise is slower, and the elevated pressures endurance is long, and the energy of release is large, and collapsing force is strong.For releasing; comprising normally releases releases with nonflame; be the active explosion that utilizes bursting diaphragm, explosion proof door, nonflame bleed-off system to take when blasting protected equipment, the way of the explosion pressure of releasing is carried out pressure release, has reached the safety of protection powder processing apparatus.Explosion proof door is commonly used to protect powder processing apparatus, as dust collection, cyclone collector etc., and pressure releasing with there being releasing of flame and powder.
Model utility content
The purpose of this utility model is to provide a kind of explosion-proof decompression device, it is simple and practical, low cost of manufacture, when the pressure in dust collection container and deduster reaches rated pressure, can realize initiatively pressure release of automatic control, pressure release is active in one's movements, and performance safety is reliable, can not cause the damage of equipment.
The purpose of this utility model is to realize like this, a kind of explosion-proof decompression device, on the port of deduster, mouthpiece is installed, on mouthpiece suitable for reading by the articulated explosion proof door of hinged seat, sealing gasket is installed below explosion proof door, sealing gasket matches with the suitable for reading of mouthpiece, at the articulated hook of free end of explosion proof door, hook matches with affixed block on mouthpiece, make explosion proof door by the sealing suitable for reading of mouthpiece, electromagnetism sensitive switch is installed on the mouthpiece of block bottom, and the armature of electromagnetism sensitive switch matches with the side end face of hook gib head.
The utility model is the articulated explosion proof door that sealing gasket is housed on the mouthpiece of deduster suitable for reading, the hook hinged at the free end of explosion proof door matches with the block on mouthpiece, on the mouthpiece of block bottom, magnetic switch is installed, the armature of magnetic switch matches with the gib head side end face of hook.
According to dust explosive concentration limit design force value, when in dust collection, cyclone collector, dust explosive concentration reaches design pressure value, the signal of exporting by sensor imports automatic control system into, and the magnetic switch on automatic control system explosion-proof decompression device is backed down explosion proof door by hook and opened pressure release.After pressure release, remind in time field personnel to process the dust in dust collection, cyclone collector, can not cause the damage of equipment.
The utility model is simple and practical, and low cost of manufacture, when the pressure in dust collection container and deduster reaches rated pressure, has realized initiatively pressure release of automatic control, and pressure release is active in one's movements, and performance safety is reliable, can not cause the damage of equipment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is main TV structure schematic diagram of the present utility model.
