A fire extinguishing agent filling device for a water-based fire extinguisher

Abstract

This utility model relates to a filling device for extinguishing agents in water-based fire extinguishers, belonging to the field of filling technology. The device includes a base with two sliding chambers fixedly connected to the top, and clamping mechanisms fixedly connected to adjacent sides of the two chambers. Through the addition of a stirring mechanism, during the up-and-down movement of the storage cylinder, the stirring blades within the mechanism stir the extinguishing agent. Because the end of the stirring blade that contacts the storage cylinder is arc-shaped, it can carry undissolved precipitates upwards, preventing them from entering the fire extinguisher canister and clogging the nozzle. Furthermore, as the stirring blades carry the precipitates upwards, they agitate the extinguishing agent, further dissolving any undissolved precipitates and improving the uniformity of the extinguishing agent. This ensures that the extinguishing agent composition ratio is essentially consistent in each filled fire extinguisher, thus guaranteeing the performance of the fire extinguisher.

Description

Technical Field

[0001] This utility model belongs to the field of filling technology, specifically relating to a filling device for extinguishing agents in a water-based fire extinguisher. Background Technology

[0002] The filling requirements for water-based fire extinguishers are as follows: Fire extinguishing agent composition requirements: Deionized water or purified water to avoid impurities clogging the nozzle or corroding the container; Additives: Surfactants, flame retardants, and antifreeze agents; Filling process requirements: Proportioning and mixing: The ratio of the extinguishing agent concentrate to water must be according to the manufacturer's technical specifications (usually 1:3 to 1:10), and the mixture must be stirred evenly after mixing; pH control: 6.0~9.0 (to avoid corrosion of the fire extinguisher shell); Filling volume: Filling volume error ≤±1%; Leave 5%~10% gas phase space (to prevent thermal expansion and bursting); Filling environment: Temperature 5~40℃, relative humidity ≤80%, no dust.

[0003] Currently, when filling water-based fire extinguishing agents, since the extinguishing agent consists of water and additives, it is necessary to ensure the uniformity of the extinguishing agent mixture during the filling process. This is to ensure that the proportion of extinguishing agent components in each fire extinguisher is the same, thus guaranteeing the fire extinguishing quality of each fire extinguisher. However, long-term storage of extinguishing agents can lead to sedimentation, which will cause uneven distribution of the extinguishing agent and affect the uniformity of the extinguishing agent filling in each fire extinguisher. Based on this, a fire extinguishing agent filling device for water-based fire extinguishers is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed extinguishing agent filling device for water-based fire extinguishers in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A fire extinguishing agent filling device for a water-based fire extinguisher includes a base, two slide chambers fixedly connected to the top of the base, a clamping mechanism fixedly connected to adjacent sides of the two slide chambers, a slider slidably connected inside the slide chambers via a lifting mechanism, a storage cylinder fixedly connected to one side of the slider, an addition pipe fixedly connected to the side wall of the storage cylinder, a pump body fixedly connected to the bottom of the storage cylinder, an injection pipe fixedly connected to the bottom of the pump body, a baffle plate fixedly connected to the outer surface of the injection pipe, and a stirring mechanism installed inside the storage cylinder.

[0007] As a further optimization of this utility model, the clamping mechanism includes an electric telescopic rod fixedly connected to the adjacent sides of the two slides, a clamping plate fixedly connected to the output end of the electric telescopic rod, the clamping plate being attached to the top of the base, and rubber pads fixedly connected to the adjacent sides of the clamping plate.

[0008] As a further optimization of this utility model, the lifting mechanism includes a lifting motor fixedly connected to the top of the slide, and a lead screw is fixedly connected to the output end of the lifting motor.

[0009] As a further optimization of this utility model, the lead screw is rotatably connected to the slide, and the lead screw passes through the slider and is connected to the slider by a thread.

[0010] As a further optimization of this utility model, the stirring mechanism includes a rotating shaft that is rotatably connected in a sealed manner in the middle of the storage cylinder. Gears are fixedly connected to both ends of the rotating shaft, and stirring blades are fixedly connected to the outer surface of the rotating shaft. The stirring blades are in contact with the inner surface of the storage cylinder.

[0011] As a further optimization of this utility model, toothed rods are fixedly connected to the adjacent sides of the two slides. The toothed rods mesh with gears and pass through both ends of the storage cylinder and are slidably connected to the storage cylinder.

[0012] The beneficial effects of this utility model are as follows: Through the setting of the stirring mechanism, during the up-and-down movement of the storage cylinder, the stirring blades within the stirring mechanism stir the extinguishing agent within the storage cylinder. Furthermore, because the end of the stirring blade that contacts the storage cylinder is arc-shaped, it can carry undissolved precipitates upwards, preventing precipitates from entering the fire extinguisher canister and causing blockage of the fire extinguisher nozzle. While carrying the precipitates upwards, the stirring blades also agitate the extinguishing agent, further dissolving the undissolved precipitates and improving the uniformity of the extinguishing agent. This ensures that the proportion of extinguishing agent components in each filled fire extinguisher is basically consistent, thus ensuring the performance of the fire extinguisher.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a fire extinguishing agent filling device for a water-based fire extinguisher includes a base 1. Two sliding chambers 2 are fixedly connected to the top of the base 1. A clamping mechanism is fixedly connected to the adjacent sides of the two sliding chambers 2. The clamping mechanism includes an electric telescopic rod 3 fixedly connected to the adjacent sides of the two sliding chambers 2. A clamping plate 4 is fixedly connected to the output end of the electric telescopic rod 3. The clamping plate 4 is attached to the top of the base 1. Rubber pads 5 are fixedly connected to the adjacent sides of the clamping plate 4. The clamping surface of the rubber pads 5 is provided with anti-slip texture to ensure the stability of clamping the fire extinguisher canister while preventing damage to the canister. The sliding chambers 2 are slidably connected by a lifting mechanism. The slide block 8 is connected to the lifting mechanism, which includes a lifting motor 6 fixedly connected to the top of the slide chamber 2. A lead screw 7 is fixedly connected to the output end of the lifting motor 6. The lead screw 7 is rotatably connected to the slide chamber 2. The lead screw 7 passes through the slide block 8 and is connected to the slide block 8 by a thread. A storage cylinder 9 is fixedly connected to one side of the slide block 8. An addition tube 10 is fixedly connected to the side wall of the storage cylinder 9. A sealing plug is installed inside the addition tube 10. A pump body 11 is fixedly connected to the bottom of the storage cylinder 9. An injection tube 12 is fixedly connected to the bottom of the pump body 11. A baffle plate 13 is fixedly connected to the outer surface of the injection tube 12. A stirring mechanism is installed inside the storage cylinder 9.

[0022] In use, first place the fire extinguisher canister between the clamps 4, then activate the electric telescopic rod 3 to extend it, thereby clamping and fixing the fire extinguisher canister with the clamps 4 and rubber pads 5. This prevents displacement of the fire extinguisher canister when injecting the extinguishing agent, ensuring the stability of the extinguishing agent injection. Then, activate the lifting motor 6 to rotate the lead screw 7 clockwise, causing the slider 8 to move the storage cylinder 9 downwards until the injection tube 12 is inserted into the fire extinguisher canister and the baffle 13 is flush with the opening of the fire extinguisher canister, but without obstructing the fire extinguisher canister. The opening is sealed to prevent external pollutants from entering the fire extinguisher canister through the opening during the filling process. At this time, the pump body 11 can be started to inject the extinguishing agent into the fire extinguisher canister through the injection pipe 12. After the injection is completed, the pump body 11 is turned off, and the lifting motor 6 is started to make the lead screw 7 rotate in the opposite direction, which in turn makes the slider 8 move the storage cylinder 9 upward until the slider 8 slides to the highest position of the inner surface of the slide chamber 2. At this time, the electric telescopic rod 3 is started to shorten the electric telescopic rod 3. The clamping plate 4 and the rubber pad 5 can no longer clamp and fix the fire extinguisher canister, and the filled fire extinguisher canister can be removed.

[0023] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the stirring mechanism includes a rotating shaft 14 that is rotatably connected to the middle of the storage cylinder 9. Gears 15 are fixedly connected to both ends of the rotating shaft 14. A stirring blade 17 is fixedly connected to the outer surface of the rotating shaft 14. The stirring blade 17 is in contact with the inner surface of the storage cylinder 9, and the end of the stirring blade 17 that is in contact with the storage cylinder 9 is set to be arc-shaped. Toothed rods 16 are fixedly connected to the adjacent sides of the two sliding chambers 2. The toothed rods 16 mesh with the gears 15. The toothed rods 16 pass through both ends of the storage cylinder 9 and are slidably connected to the storage cylinder 9.

[0024] During the up-and-down movement of the storage cylinder 9, the gear 15 will drive the rotating shaft 14 to rotate under the action of the toothed rod 16, thereby causing the stirring blade 17 to stir the extinguishing agent in the storage cylinder 9. Since the end of the stirring blade 17 that is in contact with the storage cylinder 9 is set to be arc-shaped, it can carry undissolved precipitates upward, preventing precipitates in the storage cylinder 9 from entering the fire extinguisher canister and causing blockage of the fire extinguisher nozzle. When the stirring blade 17 carries the precipitates upward, it can stir the extinguishing agent, allowing the extinguishing agent to further dissolve the undissolved precipitates, improving the uniformity of the extinguishing agent, thereby ensuring that the proportion of extinguishing agent components in each fire extinguisher is basically the same, ensuring the performance of the fire extinguisher.

[0025] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
