[0002] There are large areas of coal field fires in our country. The annual coal loss due to burning is 10 million tons, and the economic loss exceeds 20 billion yuan. A large amount of SO2, H2S, CO and CO2 gases are generated by coal spontaneous combustion, seriously polluting the environment; coal field fires also cause large-scale vegetation damage and soil desertification. According to the characteristics of coal seam spontaneous combustion, grouting or water injection technology is usually adopted, mainly by the action of water to absorb the heat energy stored in the space around the coal body and reduce the coal temperature.

[0003] Chinese patent document CN219816002U discloses a stirring device for coal field fire extinguishing fluid materials, including a main body. A base is fixedly installed at the bottom of the main body. A fixing block is threadedly installed at the bottom of the base. An isolation ring is fixedly installed at a side of the bottom of the base away from the center. A load-bearing block is fixedly connected to the bottom of the connecting column. An outlet is fixedly installed on the front surface of the main body. A closing block is movably connected to the top of the outlet. A filter screen is fixedly installed inside the outlet. In the utility model, by starting two groups of motors to drive the connecting rods to rotate, the connecting rods are fixedly connected with spiral blades, and bearings are fixedly connected to the bottoms of the connecting rods. When the connecting rods are connected to the motors through the notches, power is provided to the spiral blades, and the spiral blades rotate to stir and mix the fluid materials. Because the use of two groups of spiral blades greatly improves the mixing and viscosity of the fluid materials, it is more suitable for stirring the coal field fluid materials.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-5 shown, a stirring device for a coalfield fire extinguishing fluid material includes a stirring tank 1. Two first support frames 11 are fixed to the lower part of the outer surface of the stirring tank 1. The two first support frames 11 are used to facilitate the placement of the stirring tank 1. A feed pipe 12 is also fixed to the upper right side of the outer surface of the stirring tank 1. A discharge pipe 13 is also opened on the lower left side of the outer surface of the stirring tank 1. And both the feed pipe 12 and the discharge pipe 13 communicate with the inside of the stirring tank 1, which can facilitate feeding and discharging. A feeding auger 14 is rotatably installed in the inner cavity of the stirring tank 1. At the same time, the feeding auger 14 is used to convey the materials in the stirring tank 1. A plurality of installation grooves 15 are also opened inside the rotating shaft of the feeding auger 14. A stirring assembly 2 is arranged in the installation grooves 15. The installation grooves 15 are used for the installation of the stirring assembly 2. Further, while the device conveys the materials in the stirring tank 1, it can also stir the materials, improving the working efficiency of the device. A transmission assembly 3 is also arranged at the right end of the stirring tank 1. The transmission assembly 3 is used to control the feeding auger 14 and the stirring assembly 2.

[0022] As Figure 3 and Figure 4As shown in the figure, the stirring assembly 2 includes an installation box body 21 fixedly connected to the feeding auger 14. The installation box body 21 is fixed in the installation groove 15, so that when the feeding auger 14 rotates relative to the stirring tank 1, the installation box body 21 can also rotate relative to the stirring tank 1. A transmission shaft 22 is rotatably installed inside the installation box body 21, and the transmission shaft 22 and the installation box body 21 are designed with concentric axes, so that the transmission shaft 22 can rotate relative to the installation box body 21. A stirring auger 23 is rotatably installed on the outer surface of the installation box body 21. The stirring auger 23 can also be a stirring blade. When the stirring auger 23 rotates, it can stir the materials conveyed by the feeding auger 14 to enhance the stirring effect. The transmission shaft 22 and the stirring auger 23 are connected by a bevel gear set 24. The spiral part of the stirring auger 23 is located inside the stirring tank 1, and the rotating shaft of the stirring auger 23 is rotatably connected to the installation box body 21 and the feeding auger 14. Further, when the device is in use, the stirring auger 23 can stir the materials conveyed by the installation groove 15, and further, the device can stir the materials during the transmission process, improving the working efficiency of the device.

[0023] As Figure 3 and Figure 5 shown in the figure, the transmission assembly 3 includes a driving motor 31 fixed to the right end of the stirring tank 1. The driving motor 31 is a prior art. A second support frame 32 is also fixed to the right end of the stirring tank 1. A first transmission gear 33 fixedly connected to the feeding auger 14 is rotatably installed at the right end of the stirring tank 1. A second transmission gear 34 meshing with the first transmission gear 33 is fixed to the output end of the driving motor 31. Further, when the driving motor 31 works, it can drive the first transmission gear 33 to rotate, thereby driving the discharge pipe 13 to rotate. A plurality of transmission shafts 22 are fixedly connected, and the transmission shafts 22 are fixedly connected to the second support frame 32. Through the fixed connection between the transmission shafts 22 and the second support frame 32, further, when the feeding auger 14 rotates, the transmission shafts 22 will not rotate. The transmission shafts 22 are rotatably connected relative to the feeding auger 14. Due to the fixed connection between the transmission shafts 22 and the second support frame 32, when the feeding auger 14 rotates, it will not cause the feeding auger 14 to rotate. Further, the transmission shafts 22 can rotate in the opposite direction relative to the feeding auger 14.

[0024] The specific implementation mode of this embodiment is as follows: When the device is in use, pour the fluid material to be stirred into the stirring tank 1 through the feeding pipe 12, and then start the driving motor 31. When the driving motor 31 works, it drives the feeding auger 14 to rotate through the first transmission gear 33 and the second transmission gear 34. When the feeding auger 14 rotates, it conveys the fluid material in the stirring tank 1, and then the fluid material is discharged through the discharge pipe 13.

[0025] When the feeding auger 14 rotates, due to the fixed connection between the transmission shaft 22 and the second support frame 32, the transmission shaft 22 will rotate relative to the transmission shaft 22, and then drive the stirring auger 23 to rotate through the bevel gear set 24. When the stirring auger 23 rotates, it can stir the materials in the mixing tank 1. The device uses the feeding auger 14 and the stirring auger 23 to stir together. At the same time, through the transmission of the feeding auger 14, the working efficiency of the device can be improved, and the stirring effect of the device can also be enhanced.

[0026] It should be noted that the specific installation methods, circuit connection methods, and control methods of the feeding auger 14, the stirring auger 23, the drive motor 31, etc. in the present utility model are all conventional designs, and the present utility model will not be elaborated in detail.

[0027] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
