Description

Technical Field

[0001] This utility model relates to the field of coal mine sealing technology, and in particular to a storage device for silicate-modified polyurethane material for reinforcing coal and rock masses in coal mines. Background Technology

[0002] During coal mining, it is often necessary to reinforce the coal and rock mass to improve safety. Currently, conventional borehole sealing uses a two-plug-one-injection process, employing 425 cement and a grout prepared with a cement:water:hydrogen slurry ratio of 100:30:2. The injection pressure is controlled at 1.6–2.0 MPa, and the grout is pumped into the borehole through the injection pipe. The grout must solidify for 8 hours before detonation. This long solidification and warning time disrupts normal production. Currently, coal mines are using silicate-modified polyurethane material for reinforcing coal and rock masses. This material offers a shorter sealing time, allowing for detonation within 3 minutes, resulting in a stable and safe sealing effect.

[0003] Silicate-modified polyurethane materials used for reinforcing coal and rock masses in coal mines are typically two-component liquids, consisting of resin (component A) and a catalyst (component B). Component A is generally a colorless or semi-transparent liquid, mainly composed of a mixture of silicate and small-molecule polyols; component B is a clear, brownish-red liquid, mainly composed of polymeric MDI (diphenylmethane diisocyanate). Both components are stable at room temperature, but when mixed in a specific volume ratio (usually 1:1), a chemical reaction occurs to form a solidified body. Therefore, silicate-modified polyurethane materials are stored separately for components A and B, and mixed before use.

[0004] Current storage devices are simple sealed containers, which present challenges in coal mine sealing operations due to limited working space. Once fixed in one location, the storage device is difficult to move, making it difficult to remove the silicate-modified polyurethane material during subsequent sealing operations at different locations. Therefore, this invention proposes a storage device for silicate-modified polyurethane material used in coal mine reinforcement to address the shortcomings of existing technologies. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a storage device for silicate-modified polyurethane materials used in coal mine reinforcement. By setting a rotatable first cover and a second cover on the outside of a first storage tank and a second storage tank respectively, and then setting a first conveying mechanism and a second conveying mechanism on the first cover and the second cover respectively to connect the first storage tank and the second storage tank, the first conveying mechanism and the second conveying mechanism can be adjusted synchronously to adjust the direction, thereby enabling multi-angle material discharge without moving the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A storage device for silicate-modified polyurethane material used to reinforce coal and rock masses in coal mines includes a storage shell, a partition plate, a support ring plate, a first storage bucket, and a second storage bucket. The storage shell has symmetrical openings. A partition plate is located in the middle of the interior of the storage shell. Support ring plates are located above and below the partition plate. The first storage bucket is located on the partition plate. The second storage bucket is located at the lower interior of the storage shell. A first cover is fitted around the first storage bucket, and a second cover is fitted around the second storage bucket. Both the first and second covers are rotatably connected to the support ring plates. A first conveying mechanism is located at the top of the first cover, and a second conveying mechanism is located at the top of the second cover. The first and second conveying mechanisms are respectively connected to the interiors of the first and second storage buckets.

[0007] A further improvement is that the first conveying mechanism and the second conveying mechanism have the same structure, both including a conveying pump, a conveying pipe and a connecting pipe. The input end of the conveying pump is provided with a conveying pipe, the output end of the conveying pump is provided with a connecting pipe, and a valve is provided on the connecting pipe.

[0008] A further improvement is that both the first and second storage containers can be detachably fitted with top covers, and the top covers have through holes at their centers.

[0009] A further improvement is that the lower end of the conveying pipe extends from the through hole to the inside of the first and second storage bins, and the conveying pipe is rotatably connected to the through hole via a mechanical seal.

[0010] A further improvement is that a drive rod is rotatably provided on one side between the two support ring plates, and a first drive gear and a second drive gear are provided on the drive rod. A first driven gear ring and a second driven gear ring are respectively provided on the outer walls of the first cover and the second cover. The first drive gear meshes with the first driven gear ring, and the second drive gear meshes with the second driven gear ring.

[0011] A further improvement is that a drive motor is provided on the lower set of support ring plates, and the drive rod is driven to rotate by the drive motor.

[0012] The beneficial effects of this utility model are as follows: This utility model sets a rotatable first cover and a second cover on the outside of the first storage barrel and the second storage barrel respectively, and then sets a first conveying mechanism and a second conveying mechanism on the first cover and the second cover respectively to connect the first storage barrel and the second storage barrel. The first conveying mechanism and the second conveying mechanism can be adjusted synchronously to adjust the direction, so as to realize multi-angle material discharge without moving the device, thereby improving the convenience of using the device.

[0015] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0016] according to Figure 1-3 As shown in the figure, this embodiment proposes a storage device for silicate-modified polyurethane material for reinforcing coal and rock masses in coal mines, including a storage shell 1, a partition plate 2, a support ring plate 3, a first storage bucket 4, and a second storage bucket 5. The storage shell 1 has symmetrical openings 6. The partition plate 2 is located in the middle of the interior of the storage shell 1. The support ring plate 3 is located above and below the partition plate 2. The first storage bucket 4 is located on the partition plate 2. The second storage bucket 5 is located at the lower interior of the storage shell 1. A first cover 7 is fitted on the outside of the first storage bucket 4. A second cover 8 is fitted on the outside of the second storage bucket 5. Both the first cover 7 and the second cover 8 are rotatably connected to the support ring plate 3. A first conveying mechanism 9 is located at the top of the first cover 7. A second conveying mechanism 10 is located at the top of the second cover 8. The first conveying mechanism 9 and the second conveying mechanism 10 are respectively connected to the interior of the first storage bucket 4 and the second storage bucket 5.

[0017] In use, the silicate-modified polyurethane material components A and B are stored separately in the first storage container 4 and the second storage container 5, respectively. When needed, components A and B are output by activating the first conveying mechanism 9 and the second conveying mechanism 10. When it is necessary to adjust the outlet positions of the first conveying mechanism 9 and the second conveying mechanism 10, the first cover 7 and the second cover 8 are controlled to rotate, thereby synchronizing the rotation of the first conveying mechanism 9 and the second conveying mechanism 10.

[0018] The first conveying mechanism 9 and the second conveying mechanism 10 have the same structure, both including a conveying pump 11, a conveying pipe 12, and a connecting pipe 13. The input end of the conveying pump 11 is provided with the conveying pipe 12, and the output end of the conveying pump 11 is provided with the connecting pipe 13. A valve is provided on the connecting pipe 13. When the first conveying mechanism 9 and the second conveying mechanism 10 of this utility model convey component A and component B, the conveying pump 11 is started, and then the conveying pipe 12 is used to output component A and component B from the first storage tank 4 and the second storage tank 5 respectively, and the materials are output through the connecting pipe 13.

[0019] Both the first storage bin 4 and the second storage bin 5 are detachably fitted with top covers 14, and the top cover 14 has a through hole 15 at its center. The lower end of the conveying pipe 12 extends from the through hole 15 to the lower interior of the first storage bin 4 and the second storage bin 5, and the conveying pipe 12 is rotatably connected to the through hole 15 via a mechanical seal. When the first conveying mechanism 9 and the second conveying mechanism 10 rotate with the first cover 7 and the second cover 8 to achieve angle adjustment, the conveying pipe 12 rotates synchronously within the through hole 15.

[0020] A drive rod 16 is rotatably mounted on one side between the two support ring plates 3. The drive rod 16 has a first drive gear 17 and a second drive gear 18. A first driven gear ring 19 and a second driven gear ring 20 are respectively mounted on the outer walls of the first cover 7 and the second cover 8. The first drive gear 17 meshes with the first driven gear ring 19, and the second drive gear 18 meshes with the second driven gear ring 20. A drive motor 21 is mounted on the lower set of support ring plates 3, and the drive rod 16 is driven to rotate by the drive motor 21. When the drive motor 21 is started, it drives the drive rod 16 to rotate. At this time, the first drive gear 17 and the second drive gear 18 mounted on the drive rod 16 rotate synchronously, and then drive the meshed first driven gear ring 19 and the second driven gear ring 20 to rotate respectively. The first cover 7 and the second cover 8 then rotate accordingly, thereby adjusting the direction of the first conveying mechanism 9 and the second conveying mechanism 10.

[0021] This utility model provides a rotatable first cover 7 and a second cover 8 on the outer sides of the first storage bin 4 and the second storage bin 5, respectively. Then, a first conveying mechanism 9 and a second conveying mechanism 10 are respectively provided on the first cover 7 and the second cover 8 to connect the first storage bin 4 and the second storage bin 5. The first conveying mechanism 9 and the second conveying mechanism 10 can be adjusted synchronously to adjust the direction, so as to achieve multi-angle material discharge without moving the device, thereby improving the ease of use of the device.
