Description

FIELD AIR FILLING APPARATUS OF DOUBLE OPEN TYPE WITH EXPLOSION PROOF FUNCTION}

The present invention relates to a two-pack air reservoir filling technology equipped with an explosion-proof function, more specifically, to improve the explosion-proof function against the explosion of the air cylinder and has an explosion-proof function that can be easily brought in or taken out of the air reservoir through the door of the open type It relates to a double-type reservoir filling device.

In general, divers in the water and firefighters in the event of a fire must work in an environment where breathing is difficult under normal conditions, so a separate breathing apparatus must be provided during the work.

In this case, the breathing apparatus used is portable because it should be convenient to move and use during work, and the largest configuration among the portable components is a type of air box worn on the user's shoulder and back.

Such a reservoir is often called a bombe, which is configured to be filled with a large amount of breathing air in a compressed state, and a user in a specific environment, such as a diver or a firefighter, can receive breathing air from the reservoir and can breathe. I'm trying to.

The air cylinder is supplied with a high pressure air through a compressor for compressing and supplying air to store the air in a compressed state therein.

In general, the reservoir should drain internal residual air to prevent contamination of the air inside the cylinder, if the remaining capacity has decreased after use, or if it has been unused for a long period of time (usually three months), The air is compressed and filled.

In the case of the aging of the reservoir, the explosion of the reservoir may occur in the process of filling the reservoir with high-pressure air. Therefore, the conventional Korean Patent No. 10-1638829 (registered on Dec. 2016) discloses a high-pressure breathing air. Safety Filler "has been disclosed.

Conventional high-pressure breathing safety box for breathing is formed in the receiving space to accommodate the air cylinder, the front and the opening of the filling casing, the both sides of the filling casing respectively sealed and a plurality so that the pressure in the explosion of the air cylinder contained in the receiving space is dispersed Side pressure distribution plate formed with two pressure distribution holes, the side spaced apart to the outside of the side pressure distribution plate to form a guide duct space for guiding the air discharged to the pressure dispersion hole due to the explosion of the air cylinder up and down And a closing plate and an opening / closing door rotatably installed in the opened front of the filling casing to open and close the receiving space and to install a mounting bracket on which the air cylinder is seated.

Conventional high-pressure breathing safety box for breathing in this configuration can prevent the occurrence of safety accidents due to the explosion of the reservoir, but when filling the compressed air into the reservoir, the reservoir is opened in accordance with the rotating state of the opening and closing doors. It should be lifted and inserted or lifted and inserted air reservoir after completion of filling. Due to this, there is a problem that a physical accident is given to the user who has to lift and lower the heavy reservoir during continuous charging work, and the fatigue is increased, causing an accident.

In addition, only a single-type reservoir can be seated, so only individual charging is possible, and a double-type reservoir has a problem in that charging is impossible.
