Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, and in particular to a foam fire extinguishing agent anti-settling device. 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 makes the pressure inside the bottle 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 foam. During the preparation of foam extinguishing agents, 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 seriously cause problems with foaming during subsequent spraying, thus delaying fire control. Therefore, a foam extinguishing agent anti-precipitation device is needed.

[0003] Chinese patent document CN218046225U discloses a foam fire extinguishing agent anti-settling device, including a base, a preparation tank on the base, and a drive box on the preparation tank. A rotating rod is rotatably mounted in the middle of the preparation tank, with its upper end extending into the drive box and equipped with driven bevel teeth. A motor is housed in the drive box, and the motor's output end is connected to a rotating shaft via a coupling. The end of the rotating shaft away from the motor has an active bevel tooth capable of meshing with the driven bevel teeth. A stirring assembly is provided inside the preparation tank, including a sedimentation tank at the bottom of the tank. A fixing block is located on the outer side of the rotating rod near its upper end, with L-shaped scrapers on both sides of the fixing block. A spiral conveying blade is located on the outer side of the rotating rod below the fixing block, with the diameter of the spiral conveying blade gradually increasing from top to bottom. A second fixing block is located on the outer side of the rotating rod below the spiral conveying blade, with second scrapers on both sides of the second fixing block. The base is hollow and contains an air intake assembly. This invention can reduce sedimentation and improve the uniformity of subsequent filling.

[0004] The existing technology has the following problems:

[0005] When using foam extinguishing agent anti-settling devices, they cannot effectively prevent the chemical agents from settling, resulting in uneven chemical distribution and affecting their use. Furthermore, foam extinguishing agent anti-settling devices are not convenient for discharging materials and have low strength, which affects the scraping effect. Summary of the Invention

[0006] This invention provides a foam fire extinguishing agent anti-settling device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 , Figure 2 As shown, a foam fire extinguishing agent anti-settling device includes a base 1, a preparation tank 2 fixedly connected to the upper surface of the base 1, a discharge pipe 3 fixedly connected to the lower surface of the central part of the preparation tank 2, the outer wall of the discharge pipe 3 fixedly connected to the inner cavity of the base 1, a feed pipe 4 fixedly connected to the upper surface of the preparation tank 2, and an anti-settling component 5 fixedly connected to the inner cavity of the preparation tank 2.

[0028] First, the chemical reagent is allowed to enter the preparation tank 2 through the feed pipe 4. Then, the anti-sedimentation component 5 inside the preparation tank 2 keeps the chemical reagent in a uniform state, thereby preventing sedimentation. When needed, it can be discharged through the discharge pipe 3.

[0029] like Figure 3 As shown, four support rods 57 are fixedly connected to both the upper and lower sides of the fixed barrel 56, and the opposite sides of the eight support rods 57 are fixedly connected to the inner cavity of the preparation barrel 2 respectively.

[0030] The support rod 57 enables the fixed barrel 56 to be fixed in the center of the inner wall of the preparation barrel 2 without affecting the delivery of chemical reagents by the spiral blade 55.

[0031] like Figure 4 As shown, a bevel gear 58 is fixedly connected to the left part of the outer wall of the connecting shaft 52, and an annular bevel gear 59 meshes with the lower surface of the outer wall of the bevel gear 58. The outer wall of the annular bevel gear 59 is movably sleeved with the inner cavity of the preparation barrel 2, and an annular connecting plate 511 is fixedly connected to the outer wall of the middle part of the annular bevel gear 59.

[0032] The bevel gear 58 enables the ring bevel gear 59 to rotate and move with the motor 51, thereby driving the ring guide rail 510 and the ring sealing support plate 512 to rotate and move. The ring sealing support plate 512 enables the scraper 513 and the stirring rod 514 to rotate within the inner wall of the preparation tank 2, thereby improving work efficiency.

[0033] The outer wall of the lower part of the annular bevel gear 59 is slidably connected to an annular guide rail 510, and the outer wall of the annular guide rail 510 is fixedly connected to the inner cavity of the preparation barrel 2.

[0034] The annular guide rail 510 enables the annular bevel gear 59 and the annular connecting plate 511 to rotate stably within the inner cavity of the preparation barrel 2, thereby providing auxiliary guidance.

[0035] like Figure 5As shown, an annular sealing support plate 512 is fixedly connected to the lower surface of the annular connecting plate 511. The upper surface of the annular sealing support plate 512 overlaps with the top of the inner wall of the preparation barrel 2. The inner wall of the annular sealing support plate 512 is movably sleeved with the outer wall of the four upper support rods 57. Scrapers 513 are fixedly connected to the left and right parts of the lower surface of the annular sealing support plate 512. The opposite sides of the two bevel gears 53 are movably sleeved with the inner wall of the preparation barrel 2.

[0036] The two scrapers 513 ensure that the chemical reagents inside the preparation tank 2 are completely discharged, thus preventing waste.

[0037] Several stirring rods 514 are linearly arrayed on the opposite surfaces of the two scrapers 513, and the opposite surfaces of the stirring rods 514 are respectively movably sleeved with the outer wall of the fixed barrel 56.

[0038] The stirring rod 514 can make the chemical reagent inside the preparation tank 2 evenly stirred. At the same time, since the opposite surfaces of several stirring rods 514 are movably connected to the outer wall of the fixed tank 56, the support strength between the two scrapers 513 can be enhanced, thereby making it easier for the scrapers 513 to clean the inner wall of the preparation tank 2.

[0039] like Figure 6 As shown, the anti-sedimentation component 5 includes a motor 51. The left side of the motor 51 is fixedly connected to the inner cavity of the upper left part of the preparation tank 2. The output end of the motor 51 is fixedly connected to a connecting shaft 52. The outer wall of the middle part of the connecting shaft 52 is rotatably connected to the inner cavity of the upper part of the preparation tank 2. A bevel gear 1 53 is fixedly connected to the right side of the connecting shaft 52. A bevel gear 2 54 meshes with the lower surface of the outer wall of the bevel gear 1 53. A spiral blade 55 is fixedly connected to the lower surface of the bevel gear 2 54. The outer wall of the upper part of the spiral blade 55 is rotatably connected to the inner cavity of the upper part of the preparation tank 2. A fixed tank 56 is movably sleeved on the outer wall of the lower part of the spiral blade 55.

[0040] The motor 51 causes the connecting shaft 52 to rotate, which in turn causes the bevel gear 53 to drive the bevel gear 54 and the helical blade 55 to rotate. Under the action of the helical blade 55 and the fixed barrel 56, the chemical reagent at the bottom of the preparation barrel 2 can move upward, thereby preventing the chemical reagent at the bottom of the preparation barrel 2 from settling.

[0041] The working principle of this utility model is as follows: First, the chemical reagent is introduced into the preparation tank 2 through the feed pipe 4. Then, the connecting shaft 52 is rotated by the motor 51, which causes the first bevel gear 53 to drive the second bevel gear 54 and the spiral blade 55 to rotate. Under the action of the spiral blade 55 and the fixed tank 56, the chemical reagent at the bottom of the preparation tank 2 can move upward. At the same time, the third bevel gear 58 is rotated by the motor 51. Through the action of the third bevel gear 58, the annular bevel gear 59 can rotate and move with the motor 51, thereby driving the annular guide rail 510 and the annular sealing support plate 512 to rotate and move. Through the action of the annular sealing support plate 512, the scraper 513 and the stirring rod 514 can rotate within the inner wall of the preparation tank 2, thereby keeping the chemical reagent in a uniform state and preventing sedimentation. When needed, it can be discharged through the discharge pipe 3. The two scrapers 513 ensure that the chemical reagent inside the preparation tank 2 is completely discharged, thus preventing waste.
