Description

  The present invention relates to a fire extinguishing powder stirring method for stirring fire extinguishing powder filled in a container body of a powder fire extinguisher.

As a fire extinguisher, there is known an accumulator type powder fire extinguisher in which a compressed gas is filled in a container body filled with a fire extinguishing powder, and the fire extinguishing powder is discharged by using the pressure of the compressed gas (for example, Patent Documents). 1).
In such a powder fire extinguisher, for example, when the powder fire extinguisher is refilled at an installation place or the like, the fire extinguisher powder in the container body may be solidified due to the pressure of the sudden compressed gas applied at the time of filling. is there. Moreover, even when refilled with a fire extinguishing powder that is not well stored or handled, the fire extinguishing powder in the container body may become solidified.
In such a powder fire extinguisher, when grasping the solidified state of the fire extinguisher powder in the container body without opening the cap, conventionally, the operator shakes the powder fire extinguisher and feels like the fire extinguisher powder. Grasping the solidified state, if it is in a solidified state, shake the powder fire extinguisher strongly to dissolve the fire extinguisher powder, and check the condition of the fire extinguishing powder by hand. There was no solution.

It is a perspective view which shows an example of the stirring bar currently used in this example. It is a partially longitudinal front view which shows the powder fire extinguisher in the state which has not implemented the fire extinguishing powder stirring method of the powder fire extinguisher which concerns on this invention.

Hereinafter, an example of an embodiment for carrying out a fire extinguishing powder stirring method of a powder fire extinguisher according to the present invention will be described with reference to FIGS.
FIG. 1 is an explanatory view showing an embodiment of the present invention, FIG. 2 is a perspective view showing an example of a stirrer used in the present embodiment, and FIG. 3 shows a powder fire extinguisher in a state where the present invention is not carried out. It is a partially longitudinal front view.

  The present invention provides a stirrer rotating device for rotating a stirrer 3 below a container body 2 by disposing a stirrer 3 rotatably at the bottom of a container body 2 filled with a fire extinguishing powder of the powder fire extinguisher 1. 4, the stirrer rotating device 4 was driven to rotate the stirrer 3, whereby the fire-extinguishing powder in the container body 2 was stirred.

In the powder fire extinguisher 1, as shown in FIG. 1, a valve case 6 is fastened and fixed to a mouth portion 5 of a container body 2 filled with a fire extinguishing powder and a compressed gas for pressurization by a union type cap 7. Yes.
The valve case 6 is formed with a fire extinguishing powder flow path 8 having one end opened in the container body 2 and the other end opened outside the container body 2, and a siphon tube 9 is formed in the opening opened in the container body 2. The fire extinguishing powder discharge hose 10 is attached to an opening that is attached and opens to the outside of the container body 2.
The valve case 6 is provided with an operation lever 11 for opening and closing the fire extinguishing powder flow path 8, and the fire extinguishing powder flow path 8 is opened by the operation of the operation lever 11 and the fire extinguishing powder is discharged using the pressure of the compressed gas. ing.
The container body 2 is made of a non-magnetic material such as aluminum or synthetic resin, and is made of aluminum in this example.

Further, as shown in FIG. 2, the stirrer 3 that is rotatably arranged at the bottom portion in the container body 2 is formed in a bowl shape along the bottom shape in the container body 2, and the outer surface is formed in a smooth surface. The blade portion 12 is formed on the inner surface in the vertical direction. In this example, the stirrer 3 is made of a magnetic material.
As shown in FIG. 3, a ring-shaped permanent magnet 13 that fixes the stirrer 3 to the bottom of the container body 2 is detachably disposed on the outer periphery of the bottom of the container body 2.

Further, the stirrer rotating device 4 has a pedestal portion 14 that is brought into contact with the bottom of the container body 2, and the stirrer 3 is attracted to the pedestal portion 14 from the outside of the container body 2 by a magnetic force to rotate the stirrer 3. An electric unit 15 is provided.
In this example, the electric unit 15 includes an electromagnet 16 that can be rotated and moved along the periphery of the bottom of the container body 2, and is configured to rotate the electromagnet 16 when energized. The magnetic force of the electromagnet 16 needs to be a magnetic force that attracts the stirrer 3 from outside the container body and can rotate the stirrer 3 as the electromagnet 16 rotates, and the electric unit 15 that rotates the electromagnet 16. Needs to have a torque capable of rotating the electromagnet that attracts the stirring bar 3.
The motor unit 15 is not limited to this, and although not shown in the drawings, the motor unit 15 has a magnetic field generating coil arranged in the circumferential direction along the periphery of the bottom of the container body 2 and energizes the magnetic field by energizing it. It is also possible to switch in the direction.
Further, the stirrer rotating device 4 includes a resistance meter 17 that displays a resistance value when the electromagnet 16 is rotated and the current of the electric unit 15 is observed to rotate the stirrer.

  The stirring of the fire extinguishing powder of the powder fire extinguisher 1 configured in this way is a stirrer in which a stirrer 3 is rotatably disposed at the bottom of the container body 2 and the stirrer 3 is rotated under the container body 2. The rotating device 4 is arranged, and the stirring bar rotating device 4 is driven to rotate the stirring bar 3.

In this example, the ring-shaped permanent magnet 13 that fixes the stirrer 3 to the bottom of the container body 2 is removed from the outer periphery of the bottom of the container body 2, and then the base of the stirrer rotating device 4 is placed on the bottom of the container body 2. The part 14 is brought into contact, and the electric part 15 is energized. As a result, the electromagnet 16 rotates and moves along the periphery of the bottom of the container body 2, and the stirrer 3 disposed in the container body 2 is attracted by the electromagnet 16 and rotates with the rotational movement of the electromagnet 16. The fire extinguishing powder in the main body 2 is stirred (see FIG. 1).
Thereby, the fire-extinguishing powder in the solidified state in the container body 2 is stirred and solved.

At this time, in this example, the stirrer rotating device 4 includes a resistance meter 17 that displays a resistance value when the stirrer 3 is rotated by observing a current of the electric unit 15 that rotates and moves the electromagnet 16. Therefore, since the solidified state and flow state of the fire extinguishing powder in the container body 2 can be grasped from the resistance value when the stirrer 3 is rotated, the container body is determined by the resistance value when the stirrer 3 is rotated. It can be confirmed that the fire extinguishing powder in 2 is in an appropriate flow state.
In this example, the solidified state and the flow state of the fire extinguishing powder in the container body 2 are grasped from the resistance value when the stirrer 3 is rotated, but the non-contact type of switching ON / OFF by magnetic force. By applying the proximity switch to the side surface of the container main body 2, the position and angle of the magnetic stirring member 3 can be confirmed, and it can be confirmed whether the inside is flowing.
