It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0016] The accompanying drawings in the embodiments of the present utility model: Different types of hatching lines in the drawings are not marked according to the national standard, nor are the materials of the components required. They are used to distinguish the cross-sectional views of the components in the drawings.

[0017] Please refer to Figures 1-4 , a dispensing device for the production of water-based fire extinguishing agent, including a dispensing cylinder 1, a drain pipe 2 connected to the bottom of the dispensing cylinder 1, a valve 3 installed outside the drain pipe 2, a top cover 4 fixedly installed on the top of the dispensing cylinder 1, a first feed pipe 5 and a second feed pipe 6 connected to the inside of the top cover 4, and a motor 7 fixedly installed on the top cover 4. A stirring mechanism 8 fixedly sleeved inside the top cover 4 is fixedly sleeved inside the dispensing cylinder 1. A first water pipe 9 is connected to the outside of the drain pipe 2. The top end of the first water pipe 9 is connected to a water pump 10 fixedly installed outside the dispensing cylinder 1. The water pump 10 is connected to a flow meter 11. The water-based fire extinguishing agent inside the dispensing cylinder 1 can be pumped through the first water pipe 9 by the drive of the water pump 10. At the same time, the flow rate of the water-based fire extinguishing agent flowing into the first adapter 122 can be detected by the flow meter 11, and the drive of the water pump 10 can be controlled to ensure that the flow rate of the water-based fire extinguishing agent inside the heating pipe 124 is not too fast. The flow meter 11 is connected to a second water pipe 13 arranged inside the dispensing cylinder 1 through a heating mechanism 12.

[0018] Among them, the stirring mechanism 8 includes a first fixed frame 81 fixedly sleeved inside the dispensing cylinder 1, a first electric telescopic rod 82 and a second electric telescopic rod 83 fixedly sleeved inside the top cover 4. The outer sides of the bottoms of the first electric telescopic rod 82 and the second electric telescopic rod 83 are jointly fixedly sleeved with a second fixed frame 84. A moving sleeve 85 is rotatably connected inside the second fixed frame 84. A rotating shaft 86 rotatably connected inside the top cover 4 and the first fixed frame 81 is sleeved inside the moving sleeve 85. The first fixed frame 81 can limit and support the rotating shaft 86 to prevent the rotating shaft 86 from bending. Stirring rods 87 are arranged on the outer side of the moving sleeve 85. The outer side of the top end of the rotating shaft 86 extending out of the top cover 4 is fixedly sleeved with the output shaft of the motor 7 through a shaft sleeve. Driven by the motor 7, the rotating shaft 86 can be driven to rotate while driving the stirring rods 87 on the outer side of the moving sleeve 85 to rotate synchronously. Thus, the mixed liquid inside the dispensing cylinder 1 can be stirred and mixed by the stirring rods 87. And driven by the first electric telescopic rod 82 and the second electric telescopic rod 83, the stirring rods 87 on the outer side of the moving sleeve 85 can move along the axial direction of the rotating shaft 86 while changing the position of the stirring rods 87 inside the mixed liquid, so that the stirring rods 87 can fully stir and mix each layer of the mixed liquid.

[0019] Among them, the heating mechanism 12 includes a fixed sleeve 121 arranged on the outer side of the dispensing cylinder 1 and a first rotating connecting pipe 122 communicated with the flowmeter 11. An electromagnetic heating sleeve 123 is fixedly sleeved inside the fixed sleeve 121. A heating pipe 124 located inside the electromagnetic heating sleeve 123 is communicated with the top of the first rotating connecting pipe 122. A second rotating connecting pipe 125 is communicated with the top of the heating pipe 124. The second rotating connecting pipe 125 is communicated with the second water pipe 13 through a temperature sensor 126. The temperature sensor 126 can detect the temperature of the mixed liquid inside the second rotating connecting pipe 125 while controlling the start and stop of the electromagnetic heating sleeve 123, ensuring that the electromagnetic heating sleeve 123 can heat the mixed liquid inside the heating pipe 124 within the set temperature range.

[0020] Among them, a limiting boss 14 adapted to the rotating shaft 86 is arranged inside the moving sleeve 85. When the moving sleeve 85 moves driven by the first electric telescopic rod 82 and the second electric telescopic rod 83, the moving sleeve 85 can rotate synchronously with the rotating shaft 86, so as to facilitate the adjustment of the height of the stirring rods 87.

[0021] When the dispensing device is working, additives and water are added into the interior of the dispensing cylinder 1 through the first feed pipe 5 and the second feed pipe 6. The motor 7 is started. While the rotating shaft 86 is driven to rotate by the motor 7, the stirring rod 87 is driven to rotate synchronously through the moving sleeve 85. The mixed liquid inside the dispensing cylinder 1 is stirred and mixed by the rotation of the stirring rod 87. Starting the first electric telescopic rod 82 and the second electric telescopic rod 83 can drive the moving sleeve 85 to move along the axial direction of the rotating shaft 86 through the second fixing frame 84, and at the same time, the height of the stirring rod 87 can be adjusted, so that the stirring rod 87 can stir and mix the mixed liquid of each layer. The water pump 10 and the electromagnetic heating sleeve 123 are started. The mixed liquid inside the dispensing cylinder 1 is sequentially transported through the drain pipe 2, the first water pipe 9, the flow meter 11 and the first adapter 122 to the interior of the heating pipe 124 by the drive of the water pump 10. During this process, the flow rate of the liquid flowing into the first adapter 122 is detected by the flow meter 11. The heating pipe 124 is electromagnetically heated by the electromagnetic heating sleeve 123, and heat exchange is carried out on the liquid inside it by the heating pipe 124. After heating, the mixed liquid is subjected to temperature detection by the temperature sensor 126 and then transported to the interior of the dispensing cylinder 1 through the second water pipe 13. With the continuous drive of the water pump 10, the mixed liquid inside the dispensing cylinder 1 is continuously transported to the interior of the heating pipe 124 for heating treatment.
