Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and in particular to an automatic drainage device for coal mining. Background Technology

[0002] Coal mining refers to the process of extracting coal resources from underground or the surface through excavation. Specifically, coal mining includes underground or above-ground excavation activities, involving mine operation and raw material processing at or near the mine site. During coal mining, there is often significant seepage water inside the mine, and in case of rain, it is necessary to drain the water from the mine promptly. Automatic drainage systems are typically used for this purpose.

[0003] In a current Chinese utility model application, publication number CN218062386U discloses a drainage device for controlling water in coal mines. The device includes a drainage tank containing a drainage pump. An operation button is located on one side of the drainage tank. The bottom of the drainage tank is open and fitted with a bottom filter plate. A right-side drain pipe is connected to one side of the drainage pump, with one end of the drain pipe extending outside the drainage tank. In this utility model, during coal mining, water needs to be drained promptly. The bottom filter plate filters the water before it flows into the drainage tank. Triangular frames are located on both sides of the drainage tank, with their inclined surfaces facing downwards. When encountering sand or gravel, the downward-facing inclined surfaces automatically fall off under gravity, increasing the water intake and preventing the bottom filter plate from becoming clogged, insufficient water intake, and overheating damage to the drainage pump.

[0004] Referring to the aforementioned drainage device for coal mine water control, although it can filter the coal slag mixed in the water to prevent the water pump from being affected, the filtered coal slag accumulates in the drainage tank, making it inconvenient to clean. Therefore, how to better discharge and collect the filtered coal slag is an important problem that needs to be solved in the design of automatic drainage devices for coal mines. Utility Model Content

[0005] This invention provides an automatic drainage device for coal mining to solve the problem of the inconvenience of cleaning up filtered coal slag.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides an automatic drainage device for coal mining, including a coal slag collection shell, and further comprising:

[0008] An automatic drainage structure is installed inside the slag collection shell;

[0022] In this technical solution, the sliding block descends, causing connecting rod one to descend, connecting rod one to descend, and connecting rod two to descend. Connecting rod two then causes the sealing plate to rotate downward, opening the bottom of the discharge chute. The filtered coal slag falls into the collection basket for collection, which can effectively discharge the filtered coal slag.

[0023] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0024] The positive and progressive effects of this utility model are as follows:

[0025] 1. The rotating motor drives the rotating rod to rotate, which in turn drives the threaded rod to rotate. The threaded rod drives the moving plate to move downward, which in turn drives the sliding block to move downward synchronously. The sliding block descends, causing connecting rod one to descend, which in turn drives connecting rod two to descend. Connecting rod two then drives the sealing plate to rotate downward, thus opening the bottom of the discharge chute. The filtered coal slag falls into the collection basket for collection, facilitating the discharge and collection of the filtered coal slag.

[0026] 2. The moving plate drives the push rod to descend, which in turn moves the moving rod downwards. The moving rod then moves the cleaning brush and scraper downwards. The scraper scrapes and cleans the coal slag adhering to filter screens one, two, three, and four. The cleaning brush follows closely behind, scrubbing and cleaning filter screens one, two, three, and four. This allows for simultaneous cleaning of filter screens one, two, three, and four while discharging the coal slag, preventing the coal slag from affecting their filtration efficiency.

[0045] The rotating motor 801 rotates, which drives the rotating rod 802 to rotate. The rotating rod 802 drives the threaded rod 803 to rotate. The threaded rod 803 drives the moving plate 805 to move downward. The moving plate 805 drives the push rod 804 and the sliding block 1001 to move downward synchronously.

[0046] The cleaning structure 8 includes a movable rod 811, a cleaning brush 812, a connecting plate 813, a scraper 814, and a second sealing gasket 815. The movable rod 811 is fixedly connected to the bottom of the push rod 804. The cleaning brush 812 is fixedly connected to the side walls on both sides of the movable rod 811. The second sealing gasket 815 is fixedly connected to the top of the movable rod 811. The connecting plate 813 is fixedly connected to the bottom of the movable rod 811. The scraper 814 is fixedly connected to the bottom of the connecting plate 813. The scraper 814 and the cleaning brush 812 are respectively attached to the side walls of filter screen 1 411, filter screen 2 412, filter screen 3 413, and filter screen 414.

[0047] The push rod 804 drives the moving rod 811 to move downwards. The moving rod 811 drives the cleaning brush 812 and the scraper 814 to move downwards. The scraper 814 scrapes and cleans the coal slag adhering to the filter screens 411, 412, 413, and 414 respectively. The cleaning brush 812 follows closely behind to brush and clean the filter screens 411, 412, 413, and 414. This effectively cleans the filter screens 411, 412, 413, and 414.

[0048] The sealing structure 10 includes a sliding block 1001, a first connecting rod 1002, a second connecting rod 1003, and a sealing plate 1004. The sliding block 1001 is fixedly connected to the side walls on both sides of the movable plate 805. The sliding block 1001 is slidably connected in the sliding groove 11.

[0049] The sliding block 1001 descends, causing the connecting rod 1002 to descend. The connecting rod 1002 then causes the connecting rod 2 1003 to descend. The connecting rod 2 1003 causes the sealing plate 1004 to rotate downward, opening the bottom of the discharge trough 5. The filtered coal slag falls into the collection basket 6 for collection, which can effectively discharge the filtered coal slag.

[0050] In use, the electrical components mentioned in this application are all connected to an external power supply and control switch to push the automatic drainage device. The automatic drainage device is moved to the position where drainage is needed, and the second drainage pipe 402 is connected to the water outlet pipe connected to the outside. The water pump 404 pumps water, and the water enters the water outlet pipe through the water pumping pipe 401, the filter housing 403 and the second drainage pipe 402, and is discharged to the outside through the water outlet pipe. The first filter screen 411, the second filter screen 412, the third filter screen 413 and the fourth filter screen 414 filter the coal slag mixed in the water in sequence to prevent the coal slag mixed in the water from entering the water pump 404, which would cause the water pump 404 to malfunction and fail to work properly.

[0051] After a certain amount of coal slag accumulates inside the filter housing 403, the rotating motor 801 rotates, driving the rotating rod 802 to rotate. The rotating rod 802 drives the threaded rod 803 to rotate, and the threaded rod 803 drives the moving plate 805 to move downward. The moving plate 805 drives the pushing rod 804 and the sliding block 1001 to move downward synchronously. The sliding block 1001 descends, driving the connecting rod one 1002 to descend. The connecting rod one 1002 drives the connecting rod two 1003 to descend. The connecting rod two 1003 drives the sealing plate 1004 to rotate downward, causing the bottom of the discharge trough 5 to open. The filtered coal slag falls into the collection basket 6 for collection, which can effectively discharge the filtered coal slag.

[0052] Water that falls into the collection basket 6 along with coal slag can pass through the basket and return to the ground via drain pipe 3, where it is pumped out again by pump pipe 401. Push rod 804 drives moving rod 811 downwards, which in turn drives cleaning brush 812 and scraper 814 downwards. Scraper 814 scrapes and cleans the coal slag adhering to filter screens 411, 412, 413, and 414 respectively. Cleaning brush 812 follows closely behind, cleaning filter screens 411, 412, 413, and 414. 13 and filter screen 414 are brushed and cleaned, which can effectively clean filter screen 1 411, filter screen 2 412, filter screen 3 413 and filter screen 414. The cleaned coal slag also falls into the collection basket 6 for collection. This facilitates the simultaneous cleaning of filter screen 1 411, filter screen 2 412, filter screen 3 413 and filter screen 414 while discharging coal slag, and avoids the coal slag affecting the filtration efficiency of filter screen 1 411, filter screen 2 412, filter screen 3 413 and filter screen 414.
