Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mine drainage technology, specifically relating to a filter pipe for mine water hazard prevention. Background Technology
[0002] Coal mine water control is a series of technical measures taken to prevent and control the inflow of surface water and groundwater into mines, roadways and mining areas, and to ensure the safety of mining operations. Drainage pipelines, as the core tool in this operation, play a key role in the drainage process. Through their transportation, water accumulated in the mine can be discharged in a timely manner, and they are an important component for maintaining the effective operation of the water control system. However, during long-term use, existing drainage pipes accumulate impurities such as coal slag and rock fragments carried by the coal mine water. These impurities continuously deposit inside the pipes, gradually reducing the effective flow cross-section. This not only reduces drainage efficiency and worsens the operating conditions of the drainage system, but may also lead to complete blockage of the pipes, preventing the timely discharge of mine water and creating safety hazards.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0020] This embodiment aims to provide a filter pipe for mine water hazard prevention. Its main function is to effectively filter impurities such as coal slag in the coal mine drainage pipe, ensuring the sustainability of drainage and ensuring that the drainage pipe will not be completely blocked.
[0021] Reference Figure 1-5 The filter pipe for mine water hazard prevention of this utility model includes: a U-shaped transition pipe 1, a support pipe 2, an inner filter pipe 7, and a conical filter hopper 9. The U-shaped transition pipe 1 is erected in the center of the inside of the support pipe 2. The left and right ends of the U-shaped transition pipe 1 are respectively connected to the inlet pipe 5 and the outlet pipe 6 through the inlet bend 3 and the outlet bend 4. The connection between the inlet bend 3 and the inlet pipe 5 and the connection between the outlet bend 4 and the outlet pipe 6 are arranged opposite to each other and are respectively connected to the top of the support pipe 2.
[0022] Specifically, the U-shaped transition pipe 1 is connected to the inlet bend 3 and the outlet bend 4, and the inlet bend 3 and the outlet bend 4 are connected to the inlet pipe 5 and the outlet pipe 6, respectively, via flanges. The top of the supporting pipe 2 is provided with an annular groove 10. The bottom of the flange at the connection between the inlet bend 3 and the inlet pipe 5, and the bottom of the flange at the connection between the outlet bend 4 and the outlet pipe 6 are both located within the annular groove 10 and are fixed to the supporting pipe 2 with bolts.
[0023] Understandably, for the purpose of use, the width of the annular groove 10 can be enlarged to ensure that the bottom of the connecting flange can be completely placed inside the annular groove 10.
[0024] Furthermore, referring to Figure 4 and Figure 6 The inner filter pipe 7 is located inside the left inlet side pipe of the U-shaped transition pipe 1. The top inlet end of the inner filter pipe 7 is fixed together with the left inlet end of the U-shaped transition pipe 1 and the bottom outlet end of the inlet bend pipe 3.
[0025] Specifically, the inner filter pipe 7 is provided with a first filter hole. The inlet end of the inner filter pipe 7 extends radially outward with a connecting plate 11. The connecting plate 11 is clamped at the connection between the outlet end of the inlet bend 3 and the inlet end of the U-shaped transition pipe 1, thereby stabilizing the position of the inner filter pipe 7 in the U-shaped transition pipe 1. This allows the water flow from the inlet bend 3 to first flow into the inner filter pipe 7 and then enter the U-shaped transition pipe 1 through the first filter hole. The outlet end of the inner filter pipe 7 is welded and fixed to the bottom of the middle pipe of the U-shaped transition pipe 1. A cleaning pipe 8 connected to the inner filter pipe 7 is welded to the outside of the bottom of the middle pipe of the U-shaped transition pipe 1. The outlet of the cleaning pipe 8 is threaded with a plug 12. By rotating the plug 12, the plug 12 can be removed from the cleaning pipe 8, so that the impurities in the inner filter pipe 7 can flow out through the cleaning pipe 8 or be flushed out by the water flow and fall onto the conical filter hopper 9 below the U-shaped transition pipe 1.
[0026] Reference Figure 2 and Figure 4 The conical filter 9 is placed upside down at the bottom of the inner pipe of the support pipe 2, and directly below the U-shaped transition pipe 1. The conical filter 9 is rotatably connected to the support pipe 2. That is, the conical filter 9 can rotate relative to the support pipe 2 to change the position of impurities that fall onto the conical filter 9 and are filtered by it, thus offsetting its vertical position from that of the U-shaped transition pipe 1, making it easier for staff to clean the impurities on the conical filter 9. The purpose of setting up the conical filter 9 is to filter the water flowing out of the impurity removal pipe 8, wherein the second filter hole of the conical filter 9 matches the second filter hole of the inner filter pipe 7.
[0027] Preferably, an annular baffle 13 is vertically welded to the edge of the conical filter 9, and an annular groove 201 that fits into the annular baffle 13 is provided on the inner bottom of the support pipe 2. The annular baffle 13 is rotatably disposed in the annular groove 201. The annular groove 201 is provided with a rolling surface corresponding to the bottom of the annular baffle 13. The rolling surface is composed of multiple rollers 14 distributed along the annular ring, which facilitates the operator to rotate the conical filter 9.
[0028] For example, the roller 14 can rotate about its own axis. When the bottom of the annular baffle 13 contacts the roller 14, the roller 14 will roll as the annular baffle 13 rotates. At this time, the frictional resistance comes only from the rolling friction between the contact surface between the roller 14 and the bottom of the annular baffle.
[0029] Preferably, the inner filter tube 7 is uniformly provided with a number of first filter holes, and the conical filter hopper 9 is provided with a number of second filter holes.
[0030] During use, the water in the drainage pipe first flows into the inner filter pipe 7 through the inlet pipe 5. Impurities such as coal slag will remain in the inner filter pipe 7 and be flushed to the bottom of the inner filter pipe 7 by the water flow. Every once in a while, the plug 12 on the impurity removal pipe 8 needs to be opened to clean out the impurities in the inner filter pipe 7. The impurities will fall on the top of the conical filter hopper 9 and slide down its slope to the edge of the conical filter hopper 9. The water that flows out of the impurity removal pipe 8 along with the impurities will be filtered through the conical filter hopper 9 and seep into the soil layer below. When the impurities on the conical filter hopper 9 accumulate to a certain extent, it will be rotated to make the accumulated impurities offset from the U-shaped transition pipe 1 above, making it easier for the staff to clean the impurities. At the same time, it will also provide a certain accumulation space for the impurities flowing out of the impurity removal pipe 8 later, so as not to hinder the impurities from flowing out of the impurity removal pipe 8.
[0031] This utility model effectively filters impurities such as coal slag from coal mine drainage pipes by incorporating an internal filter pipe and a debris removal pipe. The filtered impurities can be removed from the drainage pipe through the debris removal pipe, ensuring drainage efficiency, preventing complete blockage of the drainage pipes, and thus eliminating safety hazards and achieving the effect of water hazard prevention. It is understood that the above description is merely exemplary, and the embodiments of this application do not limit the scope of the invention.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
