[0030] Embodiment 1:

[0031] Please refer to Figures 1-6 , a foaming mixing device, including a mixing tank 1, a controller 24 is installed on the side of the mixing tank 1, support legs 21 for supporting the mixing tank 1 are installed at the bottom of the mixing tank 1, the support legs 21 play a role in supporting the mixing tank 1, a discharge pipe 22 is opened at the bottom of the mixing tank 1, a third valve 23 is installed on the discharge pipe 22, the third valve 23 is an electromagnetic valve, the third valve 23 is electrically connected to the controller 24, and at the same time, the support legs 21 facilitate creating a gap between the discharge pipe 22 and the ground, facilitating the discharge of the raw materials inside the mixing chamber 2 through the discharge pipe 22, and the third valve 23 is used to control the opening and closing of the discharge pipe 22.

[0032] A mixing chamber 2 is arranged inside the mixing tank 1, a plurality of feeding ports 3 are evenly opened at the top of the mixing tank 1, the feeding ports 3 communicate with the mixing chamber 2, a feeding pipe 4 is installed on each feeding port 3, a first valve 11 is installed on the feeding pipe 4, the first valve 11 is an electrically controlled valve, and the first valve 11 is electrically connected to the controller 24. Different raw materials are added through multiple feeding pipes 4 respectively, and the opening and closing of the feeding pipe 4 are controlled by the first valve 11 installed on the feeding pipe 4 to realize starting and stopping feeding, and the raw materials are added into the mixing chamber 2.

[0033] Inside the mixing chamber 2, there is a stirring assembly 10 for stirring. The stirring assembly 10 includes a motor 12, a mounting frame 13, a driving gear 14, a driven gear 15, a gear ring 16, and a stirring rod 17. The mounting frame 13 is horizontally arranged inside the mixing chamber 2 and is fixedly connected to the mixing tank 1. The motor 12 is fixed on the top of the mounting frame 13, and the output end of the motor 12 passes through the mounting frame 13. The output end of the motor 12 is fixedly connected to the driving gear 14. There are several driven gears 15. A slide rail 18 is installed at the bottom of the mounting frame 13. The slide rail 18 is annular. A plurality of sliders 19 are slidably connected to the slide rail 18. The sliders 19 correspond to the driven gears 15 one by one, and the driven gear 15 is rotationally engaged with the corresponding slider 19. The driven gear 15 moves in a circular motion around the center of the mounting frame 13. Several driven gears 15 are respectively meshed with the driving gear 14. The gear ring 16 is arranged at the bottom of the mounting frame 13, and the driven gears 15 are respectively meshed with the gear ring 16. There are several stirring rods 17, and several stirring rods 17 are respectively installed at the bottom of the driven gears 15. The stirring rods 17 are arranged at the non - center end of the driven gears 15. Installing the stirring rods 17 at the non - center end of the driven gears 15 can increase the rotation radius of the stirring rods 17 and increase the stirring area with the raw materials.

[0034] The motor 12 drives the driving gear 14 to rotate. Since the driven gear 15 is meshed with the driving gear 14, the driving gear 14 will drive the driven gear 15 to rotate. Since the driven gear 15 is restricted by the gear ring 16 and the gear ring 16 is fixed, when the driven gear 15 rotates, the driven gear 15 will roll around the gear ring 16. The cooperation of the slide rail 18 and the slider 19 plays a supporting role for the driven gear 15 to prevent the driven gear 15 from separating from the mounting frame 13. Thus, while driving the stirring rod 17 to rotate around the center of the driven gear 15, it can also rotate around the center of the driving gear 14, realizing sufficient stirring of the raw materials and ensuring the stirring effect.

[0035] An air - inlet port 5 is opened on the side of the mixing tank 1. The air - inlet port 5 communicates with the mixing chamber 2. One end of the air - inlet port 5 located outside the mixing chamber 2 is installed with an air inlet pipe 6. The air inlet pipe 6 is a three - way pipe. A second valve 20 is installed at one end of the air inlet pipe 6. Using a three - way pipe for the air inlet pipe 6 can facilitate balancing the air pressure inside the stirring chamber during feeding and facilitate the addition of raw materials. At the same time, the second valve 20 can play a sealing role to ensure the sealing performance during pressurization. The other end of the air inlet pipe 6 is installed with a high - pressure air - charging device 7. An air - charging pipe 8 is arranged inside the mixing chamber 2. One end of the air - charging pipe 8 is connected to the air - inlet port 5, and a plurality of air - outlet ports 9 are evenly opened on the outer side of the air - charging pipe 8. First valves 11 for controlling opening and closing to ensure the sealing inside the mixing chamber 2 are respectively installed on several feeding pipes 4 and the air inlet pipe 6.

[0036] The general stirring assembly 10 mixes all the raw materials. At the same time, the high-pressure air inflation device 7 compresses external air and presses it into the interior of the mixing chamber 2 through the air inlet pipe 6 and the air inflation port 5. By mixing the raw materials while stirring and pressurizing, the mixing effect of the raw materials and air can be ensured. At the same time, the two steps are carried out simultaneously, which can improve the processing efficiency. At the same time, other additions are made through the air inflation pipe 8. The air inflation pipe 8 is arranged vertically. The part of the air inflation pipe 8 located in the raw materials can directly mix air and raw materials through the air outlet 9, and the part of the air inflation pipe 8 located outside the raw materials can directly pressurize the interior of the mixing chamber 2 through the air outlet 9.

[0037] Working principle:

[0038] During use, first open the first valve 11 and the second valve 20 on the feeding pipe 4, and introduce different raw materials into the interior of the mixing chamber 2 through different feeding pipes 4. At the same time, the second valve 20 equalizes the atmospheric pressure inside the mixing chamber 2. After the feeding is completed, close the first valve 11 and the second valve 20 on the feeding pipe 4, and at the same time open the first valve 11 of the high-pressure air inflation device 7. The high-pressure air inflation device 7 starts, compresses the external air, and discharges it into the interior of the mixing chamber 2 through the air inlet pipe 6 and the air outlet 9 on the air inflation pipe 8. At the same time, the motor 12 starts. The motor 12 drives the driving gear 14 to rotate. The driving gear 14 will drive the driven gear 15 to rotate. The driven gear 15 is limited by the gear ring 16, so the driven gear 15 rotates along the gear ring 16. The driven gear 15 will drive the stirring rod 17 to rotate, and the raw materials are stirred by the stirring rod 17, realizing stirring and air inflation at the same time, ensuring the mixing efficiency of the raw materials and air. The stirred raw materials can be discharged through the discharge pipe 22.
