Description

Technical Field

[0001] This application relates to the field of mixing technology, and more specifically, to a high-water-content material mixing device for gob-side roadway retention. Background Technology

[0002] In coal mining, the technology of roadway retention along the goaf is of great significance for improving coal resource recovery rate and alleviating the tension between mining and tunneling. High-water materials (mine-grade high-water filler rapid-setting solidification materials) are widely used in roadway support along the goaf due to their characteristics such as high water content, rapid setting, early strength, high strength, and good pumpability.

[0003] In the use of high-water-content materials, powders A and B must first be mixed with a certain proportion of water and stirred separately by a mixing device to form a uniform slurry. Then, the two slurries A and B are mixed together. However, in the above process, each mixing device is relatively independent and occupies a large space. After the powders A and B are stirred separately to form slurries, they need to be transferred and transported, which prolongs the production process time, reduces production efficiency, and requires each device to be operated independently, which increases the time consumption and seriously affects production efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a high-water-content material mixing device for goaf retention, which can solve the technical problem that when using high-water-content materials, each mixing device is independent of each other, which not only occupies a lot of space, but also prolongs the production process time due to the transfer and transportation of slurry, and the time required for each device to be operated individually, resulting in seriously low production efficiency.

[0005] This application provides a high-moisture material mixing device for goaf retention, including a housing. The housing has a mixing chamber and two mixing tanks, which are symmetrically arranged above the mixing chamber. The mixing chamber contains a mixing component, and the mixing tanks contain mixing components. The top of the housing has a drive component for driving the mixing component to rotate. A transmission component is provided between the mixing component and the mixing component.

The lower part of the housing has a discharge pipe connected to the mixing chamber. The discharge pipe has a discharge valve.

[0006] Furthermore, the mixing assembly includes a mixing shaft and a plurality of mixing rods. The mixing shaft is rotatably disposed within the mixing chamber, and the upper end of the mixing shaft extends outside the housing and is connected to the drive assembly. The plurality of mixing rods are uniformly fixed on the mixing shaft.

[0007] Furthermore, the drive assembly includes a mounting plate and a drive motor. The mounting plate is fixed to the top of the housing, the drive motor is fixed to the mounting plate, the upper end of the mixing shaft is rotatably connected to the mounting plate, and the upper end of the mixing shaft is connected to the output shaft of the drive motor.

[0008] Furthermore, the stirring assembly includes a stirring shaft and a plurality of stirring rods. The stirring shaft is rotatably disposed within the stirring tank, and the upper end of the stirring shaft is rotatably connected to the mounting plate. The plurality of stirring rods are evenly fixed on the stirring shaft.

[0009] Furthermore, there are two transmission components, each corresponding to one of the stirring components.

The driving wheel is fixed on the mixing shaft, the driven wheel is fixed on the stirring shaft, and the driving wheel and the driven wheel are rotatably connected by the transmission belt.

[0027] like Figure 1 and Figure 2 As shown, this application provides a high-moisture material mixing device for gob-side roadway retention, including a housing 1. The housing 1 contains a mixing chamber 2 and two mixing tanks 3, symmetrically arranged above the mixing chamber 2. The mixing chamber 2 contains a mixing component 4, and the mixing tanks 3 contain mixing components 5. The top of the housing 1 has a drive component 6 for driving the mixing component 4 to rotate. A transmission component 7 connects the mixing component 4 and the mixing component 5. When the mixing component 4 rotates, it drives the mixing component 5 to rotate via the transmission component 7. The outer side of the housing 1 has a discharge pipe 8 connecting the mixing tanks 3 and the mixing chamber 2, and a discharge valve 9 is provided on the discharge pipe 8. The lower part of the housing 1 has a discharge pipe 10 communicating with the mixing chamber 2, and a discharge valve 11 is provided on the discharge pipe 10. When the device is started, the drive component 6 at the top of the housing 1 drives the mixing component 4 in the mixing chamber 2 to rotate. The mixing component 4 drives the mixing component 5 in the mixing tank 3 to rotate synchronously through the transmission component 7. Powder A and powder B, as well as a certain proportion of water, are added to the two mixing tanks 3 respectively. The rotating mixing component 5 stirs the powder and water to form a uniform slurry in the mixing tank 3. The discharge valve 9 is opened, and the slurry flows into the mixing chamber 2. The mixing component 4 fully mixes the powder A and powder B. Finally, the discharge valve 11 is opened, and the mixed high-water material is discharged from the discharge pipe 10 for use in the goaf. The entire device places the mixing tank 3 above the mixing chamber 2 and integrates it into the shell 1, making efficient use of space and suitable for the confined environment underground. The mixing component 4 is driven by the drive component 6, and the mixing component 4 drives the two mixing components 5 through the transmission component 7, avoiding the separate operation of multiple devices, reducing production process time and equipment transfer steps, and improving production efficiency.

[0028] like Figure 2 As shown, the mixing component 4 includes a mixing shaft 41 and multiple mixing rods 42. The mixing shaft 41 is rotatably disposed in the mixing chamber 2. The upper end of the mixing shaft 41 extends to the outside of the housing 1 and is connected to the drive component 6. The multiple mixing rods 42 are uniformly fixed on the mixing shaft 41. The drive component 6 drives the mixing shaft 41 to rotate, and the mixing shaft 41 drives the mixing rods 42 to rotate, so that the two slurries A and B can be fully mixed in the mixing chamber 2, ensuring the mixing quality of high water materials and improving the support effect of the goaf retaining roadway.

[0029] like Figure 1 and Figure 2 As shown, the drive assembly 6 includes a mounting plate 61 and a drive motor 62. The mounting plate 61 is fixed to the top of the housing 1, and the drive motor 62 is fixed to the mounting plate 61. The upper end of the mixing shaft 41 is rotatably connected to the mounting plate 61, and the upper end of the mixing shaft 41 is connected to the output shaft of the drive motor 62. The mounting plate 61 provides a stable mounting base for the drive motor 62, ensuring the stability of the entire drive structure. The drive motor 62 drives the mixing shaft 41 to rotate, providing stable power for the stirring and mixing of high-moisture materials.

[0030] like Figure 2 As shown, the stirring assembly 5 includes a stirring shaft 51 and multiple stirring rods 52. The stirring shaft 51 is rotatably disposed in the stirring tank 3. The upper end of the stirring shaft 51 is rotatably connected to the mounting plate 61. The multiple stirring rods 52 are evenly fixed on the stirring shaft 51. When the stirring shaft 51 rotates, it drives the multiple stirring rods 52 to rotate, stirring the material (powder A and a certain proportion of water or powder B and a certain proportion of water) placed in the stirring tank 3, so that the material is evenly mixed to form slurry A or slurry B.

[0031] like Figure 1 and Figure 2 As shown, there are two transmission components 7, each corresponding to one of the stirring components 5. Each transmission component 7 is specifically matched with one stirring component 5, which can realize precise power transmission and ensure that each stirring component 5 can operate stably and efficiently. This avoids the problem of uneven power distribution or unstable transmission that may occur due to sharing the transmission component 7, and ensures the consistency and reliability of the stirring work.

[0032] like Figure 1 and Figure 2 As shown, the transmission assembly 7 includes a drive wheel 71, a driven wheel 72, and a transmission belt 73. The drive wheel 71 is fixed on the mixing shaft 41, and the driven wheel 72 is fixed on the stirring shaft 51. The drive wheel 71 and the driven wheel 72 are rotatably connected by the transmission belt 73. The transmission belt 73 can buffer the power impact, making the operation of the mixing assembly 4 and the stirring assembly 5 more stable. The transmission belt 73 has an overload protection function. When encountering large resistance during the stirring process, the transmission belt 73 will slip, preventing the drive motor 62 or other components from being damaged due to overload, and ensuring the safe and stable operation of the equipment.

[0033] like Figure 2As shown, bearings 12 are provided at the connection between the mixing shaft 41 and the mounting plate 61, and at the connection between the stirring shaft 51 and the mounting plate 61. The application of bearings 12 effectively reduces the frictional resistance between the mixing shaft 41 and the mounting plate 61, and between the stirring shaft 51 and the mounting plate 61, making the rotation of the mixing shaft 41 and the stirring shaft 51 more flexible and smooth, thereby reducing energy loss and improving transmission efficiency.

[0034] like Figure 2 As shown, multiple mixing support rods 13 are uniformly fixed on the mixing rod 42. The mixing support rods 13 on adjacent mixing rods 42 are staggered. When the mixing shaft 41 drives the mixing rod 42 to rotate, the mixing support rods 13 on different mixing rods 42 can cut into the material with different trajectories, forming a complex stirring flow field. This causes the slurry to be subjected to stronger shearing and convection, allowing the slurry of different components to be more fully integrated. This significantly improves the uniformity and quality of mixing, providing high-water-content materials with stable performance for gob-side roadway retention, and improving the support effect of gob-side roadway retention.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
