Description

Technical Field

[0001] This utility model belongs to the field of gel fire extinguishing agent processing technology, specifically relating to a rapid mixing device for gel fire extinguishing agents. Background Technology

[0002] With the continuous development of new fire extinguishing agents, gel fire extinguishing agents are increasingly widely used in high-risk fire locations such as forests, grasslands, electrical facilities, and petrochemical plants due to their good adhesion, cooling properties, and coverage. However, mixing devices are required in the processing of gel fire extinguishing agents.

[0003] Current gel extinguishing agent mixing devices typically have the following drawbacks during use: First, when the demand on-site is large, after the gel extinguishing agent in the mixing device is used up, it needs to be left to stand for a period of time to be re-mixed. During this process, the device is idle, which greatly affects the fire extinguishing efficiency and delays the handling of the fire. Second, the stirring mechanism of traditional mixing devices is mostly a single stirring structure. In the field or emergency scenarios, the mixing time is long and uneven texture is prone to occur, making it difficult to ensure the continuous supply and quality stability of the gel extinguishing agent.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model features a mobile integrated carrier with two mixing tanks in the middle, enabling alternating mixing of gel fire extinguishing agents. The "seamless switching" eliminates downtime. In practical application, personnel first open the electric regulating valve on the discharge pipe section below one of the already mixed tanks, then start the delivery pump on the main feed pipe section (not shown in the diagram, but is prior art and will not be elaborated further). The mixed gel fire extinguishing agent in this tank will then be pressurized and discharged through the main feed pipe until it reaches the fire extinguishing pipe for fire suppression in the area. During this process, personnel can prepare and operate the other mixing tank. First, the required raw materials are added according to the proportions through the feed pipe, then the drive motor is started to rotate the stirring shaft, stirring... When the shaft frame initially mixes the raw materials in the tank, the first bevel gear at the end of its shaft will drive the second bevel gears on both sides and the central transmission rod to rotate. Since there are rotating shafts on both sides of the tank, the synchronous pulleys located at the same end of the rotating shafts and transmission rods can be driven by synchronous belts. At this time, the inclined stirring rods located around the rotating shafts will stir the materials again under the above-mentioned transmission. The blades of the inclined stirring rods are radially shaped with "wider outside and narrower inside". When the stirring shaft rotates, the blades apply radial force + axial force to push the materials to converge in the middle. The concentrated materials are then mixed repeatedly with the stirring shaft frame, which greatly improves the mixing efficiency, ensures uniform gel dispersion and good stability, and ensures that the tank can be quickly switched before the extinguishing agent in the first mixing tank is used up, so as to achieve uninterrupted output.

[0018] This utility model device integrates two mixing tanks together using a mobile integrated carrier, featuring a compact structure and high integration. It is suitable for portable, vehicle-mounted, or fixed use scenarios. Upon arrival at the fire-fighting area, personnel tighten multiple bolts in stages, guiding the anti-slip base to the ground under the guidance of the threaded grooves, thereby achieving stable placement of the device.

[0026] This specific embodiment is a rapid mixing device for gel fire extinguishing agents, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the device includes a mobile integrated carrier 1. A mounting plate 2 is fixed to the lower middle section of the mobile integrated carrier 1. Stabilizing mechanisms 3 are provided on the bottom sides of both sides of the mobile integrated carrier 1. Mixing tanks 4 are installed on both sides of the middle section of the mounting plate 2. An alternating mixing mechanism 5 is jointly provided inside and outside the two mixing tanks 4. The stabilizing mechanism 3 includes a fixing block 31, which is located on both sides of the bottom of the mobile integrated carrier 1. A threaded groove 32 is opened in the middle of the fixing block 31, and a bolt rod 33 is provided in the middle of the threaded groove 32. The bottom end of the bolt rod 33 is fixed with an anti-slip base 34. The bolt rod 33 and the threaded groove 32 in the middle of the fixing block 31 are connected by a threaded lifting connection. This device integrates two mixing tanks 4 together with the help of the mobile integrated carrier 1. It has the characteristics of compact structure and high integration. It is suitable for portable, vehicle-mounted or fixed use scenarios. When the fire is extinguished, the personnel turn multiple bolt rods 33 in turn. Under the guidance of the threaded groove 32, the anti-slip base 34 is pressed against the ground, thereby achieving stable placement of the device.

[0027] The alternating mixing mechanism 5 includes an alternating component 51, which is mounted on the upper and lower parts of the two mixing tanks 4. The alternating component 51 includes a feed pipe 511, which is located on the upper side of each of the two mixing tanks 4. A discharge pipe 512 is connected to the lower part of each of the two discharge pipes 512, and an electric regulating valve 513 is installed at one end of each discharge pipe 512. A three-way connector 514 is connected to the opposite ends of the two discharge pipes 512, and a main feed pipe 515 is connected to one side of the three-way connector 514. The main feed pipe 515 is connected to the two discharge pipes 512 via the three-way connector 514. A rapid mixing component 52 is installed inside and outside the two mixing tanks 4. The rapid mixing component 52 includes a fixed bracket 521, which is divided into... Located at the upper center of the two mixing tanks 4, a drive motor 522 is mounted in the center of a fixed bracket 521, and the output end of the drive motor 522 is connected to a stirring shaft bracket 523. A first bevel gear 524 is fixed around the shaft of the stirring shaft bracket 523, and second bevel gears 525 mesh with the two sides of the middle of the first bevel gear 524. A transmission rod 526 is fixed in the middle of the two second bevel gears 525. The transmission rod 526 forms a meshing transmission connection with the second bevel gears 525, the first bevel gears 524, and the stirring shaft bracket 523. Rotating shafts 527 are provided on both sides of the lower section inside the mixing tank 4, and inclined stirring rods 528 are respectively provided around the periphery of a section of the two rotating shafts 527. The transmission rods 526 and the rotating shafts 527 are on the same side. A synchronous pulley 529 is fixedly installed around one end, and a synchronous belt 5210 is fitted around the periphery of the two synchronous pulleys 529. An inclined stirring rod 528 is evenly distributed along a section of the periphery of the rotating shaft 527. Two mixing tanks 4 are provided in the middle of the mobile integrated carrier frame 1, which can realize the alternating mixing and production of gel fire extinguishing agent. The "seamless switching" eliminates the downtime gap. In actual application, the personnel first open the electric regulating valve 513 set in the discharge pipe 512 section below one of the mixing tanks 4 that has been mixed, and then start the delivery pump set in the main material pipe 515 section (not clearly shown in the figure, which belongs to the prior art and will not be described in detail). At this time, the mixed gel fire extinguishing agent in the mixing tank 4 will be pressurized and discharged through the main material pipe 515 until it is discharged to the fire extinguishing pipe to extinguish the fire in the area. During this process, personnel can prepare and operate another mixing tank 4 for mixing. First, the required raw materials are fed into the tank according to the proportion through the feed pipe 511. Then, the drive motor 522 is started to rotate the stirring shaft frame 523. When the stirring shaft frame 523 initially mixes the raw materials in the tank, the first bevel gear 524 at its shaft end will drive the second bevel gear 525 on both sides and the transmission rod 526 in the middle to rotate. Since there are rotating shafts 527 on both sides of the tank, the synchronous pulleys 529 located at the same end of the rotating shafts 527 and the transmission rod 526 can be driven by the synchronous belt 5210. At this time, the inclined stirring rods 528 located around the rotating shafts 527 will stir the materials again under the above transmission, and the blades of the inclined stirring rods 528 are radially shaped with a "wider outer and narrower inner" shape.When the stirring shaft rotates, the blades apply radial and axial forces to push the material towards the center. The concentrated material, combined with the reciprocating mixing of the stirring shaft frame 523, significantly improves mixing efficiency, ensuring uniform gel dispersion and good stability. This allows for rapid switching between tanks before the extinguishing agent in the first mixing tank 4 is used up, achieving uninterrupted output.

[0028] Working Principle: This device integrates two mixing tanks 4 together using a mobile integrated carrier 1, featuring a compact structure and high integration. It is suitable for portable, vehicle-mounted, or fixed applications. Upon reaching the fire-fighting area, personnel tighten multiple bolts 33 in stages, guiding the anti-slip base 34 to the ground under the guidance of the threaded groove 32, thus achieving stable placement of the device. Secondly, the mobile integrated carrier 1 has two mixing tanks 4 in the middle, enabling alternating mixing of the gel extinguishing agent. Seamless switching eliminates downtime. In actual application, personnel first open the electric regulating valve 513 on the discharge pipe 512 section below one of the already mixed mixing tanks 4, then start the delivery pump on the main feed pipe 515 section (not clearly shown in the diagram, belonging to existing technology and not elaborated further). At this time, the mixed gel extinguishing agent in the mixing tank 4 will be pressurized and discharged through the main feed pipe 515 until it reaches the fire-fighting area via the extinguishing pipe. During this process, personnel can adjust the other mixing tank 4. In preparation for and operation of the mixing process, the required raw materials are first fed into the tank according to the specified ratio through the feed pipe 511. Then, the drive motor 522 is started to rotate the stirring shaft frame 523. When the stirring shaft frame 523 performs initial mixing of the raw materials in the tank, the first bevel gear 524 at its shaft end will drive the second bevel gears 525 meshing on both sides and the transmission rod 526 in the middle to rotate. Since there are rotating shafts 527 on both sides inside the tank, the synchronous pulleys 529 located at the same end of the rotating shafts 527 and the transmission rods 526 can be meshed by the synchronous belt 5210. During the combined drive, the inclined stirring rods 528, which are located around the rotating shaft 527, will stir the material again under the above drive. The blades of the inclined stirring rods 528 are radially shaped with "wider outer and narrower inner". When the stirring shaft rotates, the blades apply radial force and axial force to push the material to converge towards the center. The concentrated material is then mixed with the stirring shaft frame 523, which greatly improves the mixing efficiency, ensures uniform gel dispersion and good stability, and ensures that the tank can be quickly switched before the extinguishing agent in the first mixing tank 4 is used up, so as to achieve uninterrupted output.

[0029] All technical features in this embodiment can be freely combined according to actual needs.
