Abstract
Description
Technical Field
[0001] This application relates to the technical field of fire extinguishing agent production equipment, and in particular to a production device for a lithium battery-specific foam fire extinguishing agent. Background Technology
[0002] Foam extinguishing agents are commonly used agents for extinguishing fires involving flammable and combustible liquids. They consist of various components such as foaming agents and foam stabilizers. They rely on generating a large amount of foam to cover the burning material and isolate oxygen. At the same time, some components can reduce the temperature of the burning material, thereby extinguishing the fire. In the production process of foam fire extinguishers, the mixing device is crucial. The raw materials of foam extinguishing agents have different properties. If they are not mixed sufficiently, the extinguishing effect will be seriously affected.
[0003] A search revealed that Chinese patent application number CN202223265913.5 discloses a mixing device for producing foam fire extinguishing agents, relating to the field of foam fire extinguishing agent production technology. The device includes a mixing tank body, with support legs connected to the bottom of the mixing tank body, a top cover on the top of the mixing tank body, an inlet on the top of the top cover, a drive motor on one side of the inlet, and a motor drive shaft mounted on the bottom of the drive motor.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The above-mentioned solutions involve opening a circulation pump to draw the precipitated material from the discharge pipe into the mixing tank body for remixing. However, in actual use, the stirring blades and rotating disc structure have limited effects on the agitation and shearing of the material during the mixing process, resulting in low mixing efficiency. It is difficult to achieve thorough and uniform mixing of multiple raw materials in a short time. Furthermore, there are areas within the mixing tank that the stirring blades cannot reach, forming dead zones in the mixing process, leading to insufficient mixing of materials in these areas. Utility Model Content
[0005] To address the problems mentioned in the background section, this application provides a production apparatus for a lithium battery-specific foam fire extinguishing agent.
[0006] This application provides a production device for a lithium battery-specific foam fire extinguishing agent, which adopts the following technical solution:
[0007] A production device for a lithium battery-specific foam fire extinguishing agent includes a mounting shell.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0025] This application discloses a production apparatus for a lithium battery-specific foam fire extinguishing agent. For example... Figure 1-5 As shown, a lithium battery-specific foam fire extinguishing agent production device includes a mounting shell 1. A stirring cylinder 2 is installed on the lower side of the inner wall of the mounting shell 1. A sealing plate 3 is detachably connected to the upper side of the inner wall of the stirring cylinder 2. A universal ball 4 is movably fitted on the upper side of the sealing plate 3. A stirring rod 5 is fixedly connected to the universal ball 4. A mounting plate 6 is installed on the upper side of the inner wall of the mounting shell 1. An external gear plate 7 is fixedly connected to the lower side of the mounting plate 6. A rotating shaft 8 is rotatably fitted on the upper side of the mounting plate 6. A connecting rod 9 is fixedly connected to the lower side of the external gear plate 7 at the lower end of the rotating shaft 8. A driving mechanism 10 is provided on the upper side of the inner wall of the mounting shell 1. The lithium battery-specific foam fire extinguishing agent production device uses the mounting shell 1 as the main frame, integrates core components such as the stirring cylinder 2 internally, and has feeding and driving mechanisms externally. All parts work together to realize the production of fire extinguishing agent.
[0026] Please see Figure 4 The drive mechanism 10 includes a worm gear 101 rotatably fitted on the inner wall of the mounting housing 1. A worm wheel 102, meshing with the worm gear 101, is fixedly connected to the upper end of the rotating shaft 8. A gear 103 is fixedly connected to the upper end of the stirring rod 5. A motor 104 is mounted on one side of the mounting housing 1. The gear 103 meshes with the outer side of the external gear disk 7. The output end of the motor 104 extends into the interior of the mounting housing 1 and is fixedly connected to one end of the worm gear 101. The motor 104 serves as a power source, with its output end connected to the worm gear 101. The rotation of the motor 104 drives the worm gear 101 to rotate. The worm gear 101 meshes with the worm wheel 102, converting the rotation of the worm gear 101 into the rotation of the worm wheel 102 and the rotating shaft 8. Simultaneously, the gear 103 at the upper end of the stirring rod 5 meshes with the external gear disk 7, causing the stirring rod 5 to rotate on its own axis while revolving around the rotating shaft 8, enhancing the stirring effect and making the raw materials more evenly mixed.
[0027] Please see Figure 2 A feeding mechanism 11, which cooperates with the drive mechanism 10, is provided on one side of the mounting shell 1. The feeding mechanism 11 includes a feeding cylinder 111 installed on one side of the mounting shell 1. A rotating rod 112 is rotatably fitted on the inner wall of the feeding cylinder 111. An auger blade 113 is installed on the outer side of the rotating rod 112. A feeding hopper 114 is fixedly connected to the upper side of the feeding cylinder 111, and a conveying pipe 115 is fixedly connected to the lower side of the feeding cylinder 111. The rotating rod 112 cooperates with the inner wall of the feeding cylinder 111, and the lower end of the conveying pipe 115 is connected to one side of the mixing drum 2. The raw material is poured into the feeding cylinder 111 from the feeding hopper 114. The rotating rod 112 rotates inside the feeding cylinder 111, and the auger blade 113 on its outer side rotates accordingly. Using the screw conveying principle, the raw material is conveyed from the feeding cylinder 111 to the mixing drum 2 through the conveying pipe 115, realizing automatic conveying of the raw material and ensuring a continuous supply of raw material in the mixing drum 2.
[0028] Please see Figure 3A transmission assembly 12 is provided between the drive mechanism 10 and the feeding mechanism 11. The transmission assembly 12 includes a drive wheel 121 mounted on one end of the worm 101, and a driven wheel 122 fixedly connected to one end of the rotating rod 112. A belt 123 is provided between the drive wheel 121 and the driven wheel 122, and the drive wheel 121 and the driven wheel 122 are tensioned together by the belt 123. The drive wheel 121 is mounted on one end of the worm 101, and the driven wheel 122 is connected to the rotating rod 112. The two are tensioned together by the belt 123. When the worm 101 rotates, it drives the drive wheel 121 to rotate, and transmits power to the driven wheel 122 through the belt 123, thereby driving the rotating rod 112 to rotate, realizing the power transmission between the drive mechanism 10 and the feeding mechanism 11, so that feeding and mixing are carried out synchronously.
[0029] Please see Figure 2 A discharge pipe 13 is fixedly connected to one side of the mixing drum 2. One end of the discharge pipe 13 extends to one side of the mounting shell 1 and is equipped with a control valve 14. After the foam extinguishing agent is mixed, it is discharged through the discharge pipe 13. The control valve 14 can control the opening and closing of the discharge and adjust the discharge speed.
[0030] Please see Figure 1 A protective shell 15 is installed on one side of the mounting shell 1 to cooperate with the transmission component 12. A maintenance door 16 is rotatably fitted on one side of the mounting shell 1. The protective shell 15 protects the transmission component 12, prevents foreign objects from entering and affecting the transmission, and ensures the safe operation of the device. The maintenance door 16 can be rotated and opened to facilitate the staff to inspect and maintain the inside of the device.
[0031] The implementation principle of the lithium battery-specific foam fire extinguishing agent production device according to this application embodiment is as follows: When the lithium battery-specific foam fire extinguishing agent production device is running, the motor 104 starts as a power source, and its output end drives the worm gear 101 to rotate. The worm gear 101 meshes with the worm wheel 102, transmitting power to the rotating shaft 8, causing the rotating shaft 8 to rotate, which in turn drives the connecting rod 9 and the stirring rod 5 to move. At the same time, the gear 103 at the upper end of the stirring rod 5 meshes with the external gear disk 7, allowing the stirring rod 5 to rotate on its own axis while revolving around the rotating shaft 8, thus efficiently stirring the raw materials in the stirring drum 2.
[0032] During power transmission, the driving wheel 121 at one end of the worm gear 101 drives the driven wheel 122 to rotate via the belt 123. The driven wheel 122 is connected to the rotating rod 112, causing the rotating rod 112 to rotate inside the feed cylinder 111. The auger blades 113 on its outer side use the screw conveying principle to continuously transport the raw materials poured from the feed hopper 114 into the feed cylinder 111 through the conveying pipe 115 to the mixing drum 2. After the raw materials are fully mixed in the mixing drum 2, the control valve 14 on the discharge pipe 13 is opened, and the foam extinguishing agent that has been mixed can be discharged through the discharge pipe 13. The protective shell 15 protects the transmission component 12 from external interference, and the maintenance door 16 facilitates the maintenance of the internal parts of the device by the staff, ensuring that the entire production process is stable, safe and efficient.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
