Evenly distributed support rods 7 are fixedly installed on the base 1, and evenly distributed raw material boxes 8 are fixedly installed on the top of the support rods 7. Each raw material box 8 has a discharge pipe 9 at its bottom. All feed pipes 9 are located inside the mixing tank 3. Both the feed pipe 9 and the discharge pipe 4 are equipped with regulating valves 10. Horizontal bars 11 are fixedly installed between the feed pipes 9. A liquid supply component 12 is provided above the mixing tank 3. The liquid supply component 12 includes a vertical pipe 121 fixedly installed on the horizontal bar 11, a connecting pipe 122 connected to the vertical pipe 121, an inlet pipe 123 provided on the connecting pipe 122, and a water pump 124 provided on the inlet pipe 123. Two sets of vertical pipes 121 are provided, and symmetrical heating pipes 13 are provided on the connecting pipe 122.

[0023] In use, the device stably supports the mixing box 3 through the base 1 and the support column 2. The mixing box 3 is used to mix inorganic materials. The support rod 7 is used to support the raw material box 8. The raw material box 8 is used to store different kinds of raw materials. When it is necessary to mix raw materials, the feeding pipe 9 at the bottom of the raw material box 8 is controlled by the regulating valve 10 to allow the raw materials to enter the mixing box 3. The rotating motor 6 drives the mixing box 3 to rotate. When the mixing box 3 rotates, the raw materials are stirred by the crossbar 11 on the feeding pipe 9 to achieve uniform mixing of the raw materials in the mixing box 3. The mixed material is discharged through the discharge pipe 4. The conveying pump 5 controls the discharge speed and flow rate. The entire storage and mixing process is automated.

[0024] The vertical pipe 121, as part of the liquid supply component 12, is connected to the liquid inlet pipe 123 via the connecting pipe 122 and is used to replenish the raw materials in the mixing tank 3 with diluent. The heating pipe 13 is installed on the connecting pipe 122 and the working state of the heating pipe 13 is controlled by the controller. When it is necessary to heat the diluent, the heating pipe 13 starts to work and heats the diluent to a suitable temperature. The heated diluent enters the mixing tank 3 through the vertical pipe 121, which helps to mix the raw materials quickly and improves the mixing efficiency.

[0025] The mixed inorganic materials are transported to the high-risk coal mine area for filling. The inorganic material filling device for the high-risk coal mine area has fully automated control of the entire storage and mixing process. It can easily complete the storage, metering and mixing of raw materials, effectively improving work efficiency and filling quality, making the device more convenient, efficient and practical in actual application.

[0026] The crossbar 11 is hollow and connected to the vertical pipe 121; the temperature of the crossbar 11 can be adjusted when the diluent flows, thereby further improving the mixing effect of the raw materials.

[0027] The mixing box 3 is slidably mounted on the support rod 7, and the support rod 7 has at least four evenly distributed sets; the mixing box 3 is mounted on the support rod 7 by means of sliding, and the support rod 7 has at least four sets and is evenly distributed to ensure the stability and safety of the mixing box 3 when rotating.

The controller serves as the control center of the entire filling device and is electrically connected to key components such as the delivery pump 5, the rotating motor 6, the water pump 124, and the heating tube 13. The controller can achieve precise control of these components, such as adjusting the discharge speed of the delivery pump 5, controlling the rotation speed of the rotating motor 6, adjusting the liquid inlet of the water pump 124, and setting the heating temperature of the heating tube 13. This centralized control method makes the operation of the entire filling device simpler and more efficient, while improving the filling quality and work efficiency.

[0029] Working principle:

[0030] In use, the device stably supports the mixing box 3 through the base 1 and the support column 2. The mixing box 3 is used to mix inorganic materials. The support rod 7 is used to support the raw material box 8. The raw material box 8 is used to store different kinds of raw materials. When it is necessary to mix raw materials, the feeding pipe 9 at the bottom of the raw material box 8 is controlled by the regulating valve 10 to allow the raw materials to enter the mixing box 3. The rotating motor 6 drives the mixing box 3 to rotate. When the mixing box 3 rotates, the raw materials are stirred by the crossbar 11 on the feeding pipe 9 to achieve uniform mixing of the raw materials in the mixing box 3. The mixed material is discharged through the discharge pipe 4. The conveying pump 5 controls the discharge speed and flow rate. The entire storage and mixing process is automated.

[0031] The vertical pipe 121, as part of the liquid supply component 12, is connected to the liquid inlet pipe 123 via the connecting pipe 122 and is used to replenish the raw materials in the mixing tank 3 with diluent. The heating pipe 13 is installed on the connecting pipe 122 and the working state of the heating pipe 13 is controlled by the controller. When it is necessary to heat the diluent, the heating pipe 13 starts to work and heats the diluent to a suitable temperature. The heated diluent enters the mixing tank 3 through the vertical pipe 121, which helps to mix the raw materials quickly and improves the mixing efficiency.

[0032] The mixed inorganic materials are transported to the high-risk coal mine area for filling. The inorganic material filling device for the high-risk coal mine area has fully automated control of the entire storage and mixing process. It can easily complete the storage, metering and mixing of raw materials, effectively improving work efficiency and filling quality, making the device more convenient, efficient and practical in actual application.

[0033] The crossbar 11 is hollow and connected to the vertical pipe 121, which can adjust the temperature of the crossbar 11 when the diluent flows, thereby further improving the mixing effect of the raw materials.

[0034] The mixing box 3 is mounted on the support rod 7 by sliding. At least four sets of support rods 7 are provided and evenly distributed to ensure the stability and safety of the mixing box 3 when it rotates.

[0035] As the control center of the entire filling device, the controller is electrically connected to key components such as the conveying pump 5, the rotating motor 6, the water pump 124, and the heating tube 13. The controller can achieve precise control of these components, such as adjusting the discharge speed of the conveying pump 5, controlling the rotation speed of the rotating motor 6, adjusting the liquid inlet of the water pump 124, and setting the heating temperature of the heating tube 13. This centralized control method makes the operation of the entire filling device simpler and more efficient, while improving the filling quality and work efficiency.
