Description

Technical Field

[0001] This utility model relates to the field of mine backfilling technology, and more specifically, to a connection device between underground boreholes and horizontal pipelines for mine backfilling. Background Technology

[0002] During normal mine backfilling, the mixed slurry flows under its own weight from underground boreholes into horizontal pipelines, and then through backfilling wells into the various intermediate goaf areas. However, the enormous impact force of the slurry increases the vibration of the pipelines, affecting their stability and easily causing pipe bursts. In severe cases, this can lead to shutdowns and disrupt production.

[0003] Therefore, we designed a connection device between the underground borehole and the horizontal pipeline for mine filling to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a connection device between underground boreholes and horizontal pipelines for mine filling, which can effectively reduce the sudden changes in flow rate and velocity of slurry in the pipeline, reduce pipeline vibration caused by slurry flow and environmental factors, reduce pipeline resistance and energy consumption, enhance pipeline stability and safety, and thus improve the overall flow efficiency of slurry.

[0020] Example 1

[0021] This embodiment provides a connection device for underground boreholes and horizontal pipelines in mine filling operations, such as... Figure 1 As shown, it includes a tapered pipe 1, a pressure relief pipe 2, and a bend 3 connected in sequence. The inlet of the tapered pipe 1 is connected to the borehole 5 via a flange 4. The pressure relief pipe 2 is a tee pipe. The first port of the pressure relief pipe 2 is connected to the outlet of the tapered pipe 1, the second port of the pressure relief pipe 2 is connected to the inlet of the bend 3, and the third port of the pressure relief pipe 2 is used for pressure relief. The outlet of the bend 3 is connected to a horizontal pipeline 6. The inlet flange 4 of the tapered pipe 1 is bolted to the flange 4 at the bottom of the borehole 5. The shape of the tapered pipe 1 effectively reduces sudden changes in the flow rate and velocity of the slurry in the pipeline, mitigates pipeline vibration caused by slurry flow and environmental factors, reduces pipeline resistance and energy consumption, enhances pipeline stability and safety, and thus improves the overall flow efficiency of the slurry.

[0022] Optionally, the tapered pipe 1, the pressure relief pipe 2, and the bend 3 are all connected by a clamp 7, and the outlet of the bend 3 is connected to the horizontal pipe 6 by a clamp 7.

[0023] Furthermore, the bend 3 has a curvature of 90°. The 90° bend 3 is used to reduce the flow rate of the slurry, thereby reducing equipment and production accidents caused by pipe bursts.

[0024] In this embodiment, as Figure 2 As shown, the inner walls of both the tapered pipe 1 and the pressure relief pipe 2 are provided with a wear-resistant layer 8. Optionally, a wear-resistant sleeve is installed on the inner wall of the tapered pipe 1 and the pressure relief pipe 2 to form the wear-resistant layer 8, which can extend the service life of the tapered pipe 1 and the pressure relief pipe 2.

[0025] In another embodiment of this invention, the pressure relief pipe 2 is manufactured from a filling pipe and a blind flange. A through hole is made in the middle of the filling pipe, and a blind flange is installed in the through hole to form a tee pipe. When the pressure relief pipe 2 experiences abnormal pipeline pressure or blockage, opening the blind flange can quickly release the pressure or slurry in the pipeline, which not only ensures the personal safety of employees, but also allows the slurry in the pipeline to be sprayed out through surface water, thus achieving the effect of quickly dealing with the blockage.

[0026] In summary, the embodiments of this utility model provide a connection device between a mine filling underground borehole 5 and a horizontal pipeline 6, which has at least the following advantages or beneficial effects:

[0027] This utility model has a simple design structure and is easy to install and maintain. It can effectively reduce sudden changes in the flow rate and velocity of slurry in the pipeline, reduce pipeline vibration caused by slurry flow and environmental factors, reduce pipeline resistance and energy consumption, and enhance the stability and safety of the pipeline, thereby improving the overall flow efficiency of the slurry. In addition, it can also quickly release the pressure or slurry in the pipeline when the pipeline pressure is abnormal or the pipeline is blocked, so as to quickly deal with the blockage.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
