Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a foam fire extinguishing agent processing and feeding device, including a tank body 1. The top of the tank body 1 is an open structure, and the bottom is provided with a discharge port 2. A ring rail 3 is fixedly provided on the top of the tank body 1 along the circumferential direction. A rotating ring 4 is slidably installed on the ring rail 3. A toothed ring 5 is provided on the outer wall of the rotating ring 4 along the circumferential direction. A motor 6 is installed on the side wall of the tank body 1. A gear 7 that meshes with the toothed ring 5 is installed on the driving end of the motor 6. A rotating frame 8 is fixedly provided on the upper wall of the rotating ring 4. The two ends of the rotating frame 8 are fixedly connected to the upper wall of the rotating ring 4. A stirring component extending into the tank body 1 is provided at the center of the rotating frame 8. An opening is opened on the rotating frame 8 and on one side of the stirring component. A feeding hopper 9 passes through the opening. A pair of support ears 10 are fixedly provided on both sides of the top of the feeding hopper 9, and a material blocking component is provided at the bottom. A balance sensor 11 is installed between the pair of support ears 10 and the rotating frame 8.

[0022] By adopting the above technical solution, the material is poured into the feeding hopper 9, and the weighing sensor 11 monitors the weight in real time. When the set weight is reached, the material blocking component stops feeding, the motor 6 drives the gear 7 to rotate, and the gear ring 5 drives the rotating ring 4 to rotate along the circular track 3. The feeding hopper 9 moves synchronously with the rotating frame 8. At the same time, the material blocking component is activated, so that the material falls evenly into the tank 1 along the circumference. When the rotating frame 8 rotates, it synchronously drives the stirring component to rotate, so as to stir and mix the material. The above components achieve precise quantitative feeding and efficient mixing through the linkage of weighing, rotation and stirring.

[0023] In this embodiment, the material blocking assembly includes a pair of connecting frames 12 disposed on both sides of the feeding hopper 9. A pair of horizontally arranged material blocking plates 14 are fixedly installed at the bottom of the pair of connecting frames 12 via telescopic rods 13. The upper walls of the pair of material blocking plates 14 are slidably attached to the bottom of the feeding hopper 9. An electric push rod 15 is provided on the front wall of the feeding hopper 9. A drive block 16 is installed at the telescopic end of the electric push rod 15. A pair of connecting rods 17 are hinged to the lower wall of the drive block 16. The lower ends of the pair of connecting rods 17 are hinged to the pair of material blocking plates 14.

[0024] By adopting the above technical solution, when the electric push rod 15 extends, the drive block 16 pushes open the baffle plate 14 through the connecting rod 17, and the feeding hopper 9 unloads the material; when the electric push rod 15 retracts, the baffle plate 14 closes, realizing automatic control of the unloading process.

[0025] In this embodiment, the stirring assembly includes a rotating shaft 18 fixedly installed at the center of the rotating frame 8, and a stirring rod 19 is provided on the side wall of the rotating shaft 18.

[0026] By adopting the above technical solution, the rotating shaft 18 drives the stirring rod 19 to rotate, which stirs the material, pushes the material to turn over, and improves the mixing efficiency.

[0027] In this embodiment, an auxiliary frame 20 is fixedly provided on the side wall of the tank body 1, and the upper end of the rotating shaft 18 passes through the rotating frame 8 and is rotatably connected to the auxiliary frame 20.

[0028] By adopting the above technical solution, the auxiliary frame 20 is connected to the upper end of the rotating shaft 18, which enhances the rigidity of the rotating shaft 18, prevents shaft deformation, and extends the service life of the equipment.

[0029] In this embodiment, the tank body 1 is further configured to have support legs at the bottom.

[0030] By adopting the above technical solution, the outriggers support the tank body 1, ensuring the stability of the equipment.

[0031] In this embodiment, the tank body 1 is further configured to have a mounting bracket for fixing the motor 6.

[0032] By adopting the above technical solution, the impact of motor 6 vibration on tank 1 is reduced, ensuring transmission stability.

[0033] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0034] Example: In use, an aqueous solution is introduced into the tank 1. When it is necessary to extract materials such as flame retardants and foaming agents, materials can be added to the hopper 9. The weighing sensor 11 weighs the materials in the hopper 9. When the specified weight is reached, feeding is stopped, and the motor 6 is started. The motor 6 drives the gear 7 and the gear ring 5 to rotate. The rotating ring 4 then drives the rotating frame 8 to rotate. The electric push rod 15 is started, and its telescopic end is extended, thereby causing a pair of baffles 14 to move to both sides. The materials in the hopper 9 flow downward. With the help of the rotating frame 8, the materials can be added evenly into the tank 1, avoiding local accumulation. While the rotating frame 8 is rotating, it will drive the rotating shaft 18 and the stirring rod 19 to rotate synchronously, thereby making the materials and aqueous solution fully mixed and improving processing efficiency.
