Description

Technical Field

[0001] This utility model relates to the field of foam fire extinguishing agent production technology, specifically to an anti-settling device for foam fire extinguishing agent production. Background Technology

[0002] There are many types of fire extinguishers, and foam fire extinguishers are one of them. Their extinguishing principle involves spraying a large amount of foam that adheres to the combustible material, isolating it from the oxygen in the air, thus extinguishing the fire. The foam sprayed from a foam fire extinguisher actually originates from a chemical reaction and some foaming agents. The large amount of carbon dioxide produced by the reaction inside the extinguisher creates a pressure inside the cylinder that is much higher than outside. When the nozzle is opened, the carbon dioxide, along with the large amount of foam produced by the foaming agent, is sprayed out, forming the foam. During the preparation of the foam extinguishing agent, the chemical agents are prone to precipitation in the preparation container, resulting in inconsistent chemical concentrations in the bottle during subsequent filling. This not only affects the quality but can also lead to problems with the bubbles during subsequent spraying, thus delaying fire control.

[0003] Currently, most methods for preventing sedimentation during foam fire extinguishing agent production involve shaking the foam extinguishing agent storage tank or directly inserting a stick into the foam extinguishing agent tank to stir it before filling. However, the stirring effect is poor, resulting in uneven concentration of the foam extinguishing agent raw material in the upper and lower layers; furthermore, the raw material adhering to the inner wall of the tank cannot be cleaned off, which also leads to uneven concentration of the raw material in the fire extinguisher, thus affecting the use of the foam extinguishing agent. Therefore, we propose a new anti-sedimentation device for foam fire extinguishing agent production. Utility Model Content

[0019] Please see Figure 1-3This utility model provides a technical solution: an anti-settling device for foam extinguishing agent production, including a base 1, a tank 2 fixedly connected to the top center of the base 1, an mounting frame 3 fixedly connected to the top edge of the base 1, an electric telescopic rod 4 fixedly connected to the bottom of the mounting frame 3, a tank cover 5 fixedly connected to the bottom of the electric telescopic rod 4, the tank cover 5 engaging with the tank 2, a cleaning component 6 at the bottom of the tank cover 5, an mounting plate 13 on the cleaning component 6, the mounting plate 13 being hollowed out to facilitate the flow of foam extinguishing agent raw materials, an anti-settling component 7 at the bottom of the mounting plate 13, the anti-settling component 7 including a rotating rod 7.1, a stirring blade 7.2, a liquid passage trough 7.3, and a motor 7.4, the rotating rod 7.1 being rotatably connected to the mounting plate 2 via a bearing. At the bottom of plate 13, several stirring blades 7.2 are fixedly connected to the side wall of the rotating rod 7.1 in a circular shape. The motor 7.4 is fixedly connected to the top of the mounting plate 13. The output end of the motor 7.4 passes through the mounting plate 13 and is fixedly connected to the top of the rotating rod 7.1. When stirring the foam extinguishing agent in the inner cavity of the tank 2 to prevent sedimentation, the cleaning component 6 is started to drive the anti-sedimentation component 7 to move up and down. At the same time, the motor 7.4 is started to drive the rotating rod 7.1 and the stirring blades 7.2 on it to rotate, so that the foam extinguishing agent in the inner cavity of the tank 2 can be stirred. The lower part of the side wall of the tank 2 is fixedly provided with a liquid outlet 14. A valve is provided on the liquid outlet 14, which can control the opening or closing of the liquid outlet 14 to facilitate the discharge of the foam extinguishing agent inside the tank 2 through the liquid outlet 14.

[0020] Specifically, such as Figure 2 As shown, the cleaning assembly 6 includes a cylinder 6.1, a cleaning frame 6.2, a cleaning brush 6.3, and a telescopic rod 6.4. The cylinder 6.1 is fixedly connected to the top edge of the tank cover 5. The output end of the cylinder 6.1 passes through the tank cover 5 and is fixedly connected to the cleaning frame 6.2. Several cleaning brushes 6.3 are evenly fixedly connected to the side wall of the cleaning frame 6.2. The cleaning brushes 6.3 abut against the inner side wall of the tank body 2. The telescopic rod 6.4 is fixedly connected to the other edge of the top of the tank cover 5. The telescopic rod 6.4 passes through the tank cover 5 and is fixedly connected to the other side of the top of the cleaning frame 6.2. The telescopic rod 6.4 plays a good limiting and guiding role for the cleaning frame 6.2. An installation plate 13 is fixedly connected to the inner side wall of the cleaning frame 6.2. When stirring the foam extinguishing agent inside the tank 2 to prevent sedimentation, the cylinder 6.1 is started simultaneously with the motor 7.4, pushing the cleaning frame 6.2 up and down along the side wall of the tank 2. This allows the anti-settling component 7 to stir the foam extinguishing agent while the cleaning brush 6.3 cleans the side wall of the tank 2, thus preventing the raw materials of the foam extinguishing agent from adhering to the side wall of the tank 2, which would otherwise cause uneven concentration of the extinguishing agent raw materials.

[0021] The side wall of the stirring blade 7.2 has several through-flow channels 7.3. During the rotation of the stirring blade 7.2 to stir the foam extinguishing agent, the through-flow channels 7.3 are set to ensure that the foam extinguishing agent can flow more smoothly. Several brushes 8 are fixedly connected to the bottom of the rotating rod 7.1 and the stirring blade 7.2. When the cleaning component 6 drives the anti-settling component 7 to the bottom of the inner cavity of the tank 2, the brushes 8 brush the bottom of the inner cavity of the tank 2 with the rotation of the stirring blade 7.2, which can lift up the foam extinguishing agent raw materials that have settled to the bottom of the inner cavity of the tank 2, so that the raw materials are mixed evenly and the anti-settling effect is good.

[0022] The top of the side wall of the tank 2 has a non-through annular groove 10. The bottom of the tank cover 5 is fixedly connected with a retaining ring 9. The inner cavity of the annular groove 10 is equipped with a sealing gasket, and the retaining ring 9 is sealed and engaged with the annular groove 10. In use, the raw material of the foam extinguishing agent is first added to the inner cavity of the tank 2. Then, the electric telescopic rod 4 is activated to move the tank cover 5, the cleaning component 6, the anti-settling component 7, etc. downwards. After the retaining ring 9 is engaged with the inner cavity of the annular groove 10, that is, after the tank cover 5 is sealed and engaged with the tank 2, the anti-settling treatment can begin.

[0023] Specifically, such as Figure 3 As shown, the inner walls of the mounting bracket 3 are symmetrically provided with non-through grooves 11. The side walls of the can cover 5 are symmetrically fixed with sliders 12. The sliders 12 are slidably connected to the inner cavity of the grooves 11. When the electric telescopic rod 4 pushes the can cover 5 downward, the sliders 12 move in the inner cavity of the grooves 11, which plays a good limiting and guiding role for the can cover 5, making it easy for the can cover 5 to engage with the can body 2.

[0024] It should be noted that this utility model is an anti-settling device for the production of foam fire extinguishing agents. When in use, the raw materials of foam fire extinguishing agents are first added to the inner cavity of the tank body 2, and then the electric telescopic rod 4 is started to drive the tank cover 5, cleaning components 6, anti-settling components 7, etc. to move downward. After the retaining ring 9 is engaged with the inner cavity of the annular groove 10, that is, after the tank cover 5 is sealed and engaged with the tank body 2, the anti-settling treatment can be carried out.

[0025] When stirring the foam extinguishing agent inside the tank 2 to prevent sedimentation, the cylinder 6.1 is started simultaneously with the motor 7.4. The motor 7.4 drives the rotating rod 7.1 and its stirring blades 7.2 to rotate, thus stirring the foam extinguishing agent inside the tank 2. Meanwhile, the cylinder 6.1 pushes the cleaning frame 6.2 up and down along the side wall of the tank 2's inner cavity. This allows the anti-settling component 7 to stir the foam extinguishing agent while the cleaning brush 6.3 cleans the side wall of the tank 2's inner cavity, preventing the foam extinguishing agent raw materials from adhering to the side wall and causing uneven concentration of the extinguishing agent. When the cleaning component 6 moves the anti-settling component 7 to the bottom of the tank 2's inner cavity, the brush 8, along with the rotating stirring blades 7.2, brushes the bottom of the tank 2's inner cavity, lifting any foam extinguishing agent raw materials that have settled there, ensuring uniform mixing and good anti-settling effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
