Description

Technical field:

[0001] The utility model belongs to the field of mining machinery and equipment, in particular to a mine drainage filtering device. Background technology:

[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground resource production system. In the mining process of mining enterprises, in order to ensure the safe and stable operation of the mine, it is necessary to discharge the sewage generated in the mine to avoid excessive water accumulation underground and cause safety hazards.

[0003] During the mine water discharge process, pipelines are needed to transport it remotely. The wastewater generated in the mine contains a lot of impurities, and direct discharge of these wastewaters after being transported to the ground will cause serious pollution and damage to the environment. At the same time, the impurities carried in the sewage after the transportation pipeline has been used for a long time are easy to cause pipeline blockage, resulting in the mine water cannot be discharged in time, thus causing safety hazards in the mine. Utility model content:

[0004] The purpose of the utility model is to provide a mine drainage filtering device, and overcome the deficiencies of the above-mentioned prior art, which effectively solves the existing problem that impurities carried by mine water cause pollution and damage to the environment.

[0005] The content of the utility model: A mine drainage filtering device includes a Jiaolong conveyor, a feed valve is arranged on the top wall of one end of the barrel of the Jiaolong conveyor, a filtrate port and a debris discharge port are sequentially opened on the bottom wall of the barrel of the Jiaolong conveyor, a filter screen is matched with the filtrate port, a liquid guide valve is installed on the filtrate port, and a sealing block is matched with the debris discharge port.

[0006] Furthermore, pads matching the filter screen are installed on both inner walls of the top end of the liquid guide valve, and the filter screen is placed on the pads.

[0007] Furthermore, a chute is provided below the debris discharge port, and the chute is fixedly mounted on the barrel of the Jiaolong conveyor.

[0008] Furthermore, the thickness of the filter screen is the same as the barrel wall thickness of the Jiaolong conveyor.

[0009] Furthermore, the sealing block is fixedly connected to the barrel of the Jiaolong conveyor by bolts.

[0010] The beneficial effects of the utility model are as follows: the impurities in the mine water entering into the barrel of the Jiaolong conveyor can be filtered out through the filter net, thereby avoiding the damage to the environment caused by the impurities in the mine water, and also avoiding the blockage of the pipeline for conveying the mine water. Description of the drawings:

[0011] Figure 1 It is a partial cross-sectional view of the main view of the utility model;

[0012] Figure 2 for Figure 1 Section view of the AA section;

[0013] In the figure, 1 is a Jiaolong conveyor, 2 is a feed valve, 3 is a filtrate outlet, 4 is a debris outlet, 5 is a filter screen, 6 is a liquid guide valve, 7 is a sealing block, 8 is a cushion block, and 9 is a chute. Specific implementation method:

[0014] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0015] like Figure 1 to Figure 2 As shown, a mine drainage filtering device comprises a Jiaolong conveyor 1, a feed valve 2 is arranged on the top wall of one end of the barrel of the Jiaolong conveyor 1, a filtrate port 3 and a debris discharge port 4 are sequentially opened on the bottom wall of the barrel of the Jiaolong conveyor 1, a filter screen 5 is matched with the filtrate port 3, a liquid guide valve 6 is installed on the filtrate port 3, a sealing block 7 is matched with the debris discharge port 4, pads 8 matching the filter screen 5 are installed on the inner walls on both sides of the top of the liquid guide valve 6, the filter screen 5 is placed on the pads 8, a chute 9 is arranged below the debris discharge port 4, the chute 9 is fixedly installed on the barrel of the Jiaolong conveyor 1, the thickness of the filter screen 5 is the same as the wall thickness of the barrel of the Jiaolong conveyor 1, and the sealing block 7 is fixedly connected to the barrel of the Jiaolong conveyor 1 by bolts.

[0016] Specifically, the impurities in the mine water entering the barrel of the Jiaolong conveyor 1 can be filtered out through the filter screen 5, thereby preventing the impurities in the mine water from damaging the environment.

[0017] During actual use, the mine water is transported to the feed valve 2 through a short-distance pipeline, and enters the barrel of the Jiaolong conveyor 1 through the feed valve 2. At this time, the filter screen 5 filters the impurities carried by the mine water in the barrel of the Jiaolong conveyor 1, and the filtered mine water is transported to the mine drainage system through the liquid guide valve 6, and finally transported to the ground; after the filter device has been used for a period of time, the feed valve 2 is closed to cut off the water flow. At this time, the sealing block 7 is removed, and the Jiaolong conveyor 1 is started. The spiral blades push the impurities filtered out by the filter screen 5 to the impurity discharge port 4. After the impurities fall onto the chute 9, they slide into the garbage bin for temporary storage. When the impurities are cleaned up, the sealing block 7 is installed on the impurity discharge port 4 for sealing, and the feed valve 2 is opened to restore the normal operation of the filter device; after removing the liquid guide valve 6, the filter screen 5 placed on the pad 8 can be quickly removed and replaced.

[0018] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
