Description

Technical Field

[0001] This utility model relates to the field of coal-water separation technology, specifically to an underground coal-water separation device. Background Technology

[0002] A mine shaft is a general term for the shafts, chambers, equipment, surface buildings and structures that form an underground coal mine production system. Sometimes, inclined shafts, vertical shafts, and adits in underground mine development are also referred to as mine shafts. When mining coal in a mine shaft, a large amount of water is used, which causes the coal and water to mix together after mining. Therefore, coal-water separation devices are needed to separate the coal and water.

[0003] Existing coal-water separation devices typically use gravity settling combined with a filter screen to separate coal and water. This simple separation method results in poor separation of small coal slurry and water particles, making it difficult to achieve complete separation of coal and water and causing a waste of resources. Utility Model Content

[0004] This invention proposes an underground coal-water separation device to solve the problem that existing coal-water separation devices have a relatively simple separation method for coal and water, making it difficult to achieve comprehensive separation of coal and water.

[0005] The technical solution of this utility model is as follows: An underground coal-water separation device includes a support leg, a first separation tank, a second separation tank, a connecting pipe, a vertical frame, an electric push rod, a lifting frame, a stirring and separation mechanism, a mounting plate, and a centrifugal separation cylinder. The first separation tank is installed on one side of the inner side of the support leg, and the second separation tank is installed on the other side of the inner side of the support leg. The first separation tank and the second separation tank are connected by the connecting pipe and by a connecting block. Two vertical frames are installed on the upper side of the first separation tank, and an electric push rod is provided on the inner bottom wall of the vertical frame. The electric push rod has a lifting frame connected to its telescopic end. The lifting frame moves synchronously with the telescopic end of the electric push rod. The stirring and separating mechanism is rotatably mounted on the lower side of the lifting frame. The lifting frame is equipped with a drive component for driving the stirring and separating mechanism. The stirring and separating mechanism is used for the preliminary separation of coal and water. The mounting plate is installed inside the second separation tank. A centrifugal separator is rotatably mounted on the lower side of the mounting plate. A drive component for driving the centrifugal separator to rotate is provided on the upper side of the mounting plate. The area formed between the centrifugal separator and the second separation tank is a coal slag retention area.

[0006] The stirring and separating mechanism includes a first stirring assembly and a second stirring assembly. The first stirring assembly includes a stirring shaft, a stirring frame, and a stirring bracket. The stirring shaft is rotatably mounted on the lower side of the lifting bracket. Multiple stirring frames are mounted on the outer side of the stirring shaft in a ring arrangement. The stirring bracket is mounted on the inner side of the stirring frames and rotates synchronously with the stirring shaft. The second stirring assembly includes stirring rods, scrapers, and sealing blocks. Multiple stirring rods are mounted on the bottom outer side of the stirring shaft in an inclined arrangement. The scrapers are mounted on the outer ends of the stirring rods and rotate synchronously with them. The sealing blocks are rotatably mounted on the bottom end of the stirring shaft and are used to seal the outlet of the first separating tank.

[0007] As a preferred embodiment of the underground coal-water separation device described in this utility model, in order to limit the movement of the lifting frame and ensure the stability of the lifting frame during movement, square blocks are installed on both sides of the inner wall of the vertical frame, and square slots are opened on both sides of the lifting frame, the width of the square slots being adapted to the width of the square blocks.

[0008] As a preferred embodiment of the underground coal-water separation device described in this utility model, in order to intercept large coal blocks and prevent them from entering the second separation tank through the connecting pipe, an interception layer is provided at the connection between the connecting pipe and the first separation tank, and the interception layer is composed of multiple interception nets.

[0009] As a preferred embodiment of the underground coal-water separation device described in this utility model, in order to facilitate the cleaning of coal slag retained in the coal slag retention area by the workers, a baffle assembly is installed on the outside of the second separation tank. The baffle assembly includes a mounting sleeve, a mounting bracket, a baffle plate, and bolts. Two mounting sleeves are installed on the outside of the second separation tank through two mounting blocks. The mounting bracket is inserted into the lower side of the mounting sleeve and can move vertically inside the mounting sleeve. The baffle plate is installed on the inner end of the mounting bracket and is used to block the coal slag retention area. The bolt passes through the outside of the mounting sleeve, and one end of the bolt that passes through the mounting sleeve is threaded through the mounting bracket.

[0010] The working principle and beneficial effects of this utility model are as follows:

[0011] In this utility model, the stirring and separation mechanism realizes the stirring and separation of coal and water, and the separation of large coal blocks in the coal and water. This allows the large coal blocks in the coal and water to be separated and retained inside the first separation tank, thereby achieving the initial separation of coal and water.

[0012] In this utility model, the centrifugal separation of coal slag and water entering the second separation tank is achieved through the cooperation of the mounting plate and the centrifugal separation cylinder. This allows water to enter the centrifugal separation cylinder and be discharged through the drain valve, while the coal slag remains in the coal slag retention area. This achieves secondary separation of coal and water, thereby achieving comprehensive separation of coal and water and enhancing the separation effect.

[0013] Compared with existing coal-water separation devices, which use a relatively simple method to separate coal and water, making it difficult to achieve comprehensive separation of coal and water, this underground coal-water separation device can separate large coal blocks, coal slag, and water in coal-water through multi-stage separation, achieving comprehensive separation of coal and water with good separation effect and convenient operation.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-5 As shown, this embodiment proposes an underground coal-water separation device, including a support leg 1, a first separation tank 2, a second separation tank 3, a connecting pipe 4, a vertical frame 5, an electric push rod 6, a lifting frame 7, a stirring separation mechanism, an installation plate 8, and a centrifugal separation cylinder 9. Compared with the existing coal-water separation devices, which have a relatively simple method of separating coal and water, making it difficult to achieve comprehensive separation of coal and water, this embodiment achieves the stirring separation of coal and water through the stirring separation mechanism, and achieves the separation of large coal blocks in the coal-water mixture. This allows the large coal blocks in the coal-water mixture to be separated and retained inside the first separation tank 2, thus achieving preliminary separation of coal and water. Through the cooperation of the installation plate 8 and the centrifugal separation cylinder 9, the centrifugal separation of coal slag and water entering the second separation tank 3 is achieved, allowing water to enter the centrifugal separation cylinder 9 and be discharged through the drain valve, while the coal slag is retained in the coal slag retention area, achieving secondary separation of coal and water, thus achieving comprehensive separation of coal and water and enhancing the separation effect.

[0026] like Figure 1 As shown, the first separating tank 2 is installed on one side of the inner side of the support leg 1, and a feed pipe is connected to the outer side of the first separating tank 2. The second separating tank 3 is installed on the other side of the inner side of the support leg 1, and a drain valve is connected to the lower side of the second separating tank 3. The first separating tank 2 and the second separating tank 3 are connected by a connecting pipe 4. An interception layer 10 is provided at the connection between the connecting pipe 4 and the first separating tank 2. The interception layer 10 is composed of multiple interception nets. The interception layer 10 can intercept large coal blocks separated inside the first separating tank 2, thereby preventing large coal blocks from entering the second separating tank 3 through the connecting pipe 4. The first separating tank 2 and the second separating tank 3 are connected by a connecting block. Two upright frames 5 are installed on the upper side of the first separating tank 2, as shown in the figure. Figure 2 and Figure 3As shown, an electric push rod 6 is installed on the inner bottom wall of the frame 5. A lifting frame 7 is connected to the telescopic end of the electric push rod 6. Square blocks are installed on both sides of the inner wall of the frame 5. Square slots are opened on both sides of the lifting frame 7. The width of the square slots matches the width of the square blocks. The square blocks can limit the movement of the lifting frame 7 through the square slots, thus ensuring the stability of the lifting frame 7 during lifting. The stirring and separating mechanism is rotatably installed on the lower side of the lifting frame 7. A drive component for driving the stirring and separating mechanism is installed on the lifting frame 7. The drive component is a forward and reverse rotating motor, such as... Figure 3 and Figure 5 As shown, the stirring and separating mechanism includes a first stirring assembly and a second stirring assembly. The first stirring assembly includes a stirring shaft 101, a stirring frame 102, and a stirring rack 103. The stirring shaft 101 is rotatably mounted on the lower side of the lifting frame 7. Multiple stirring frames 102 are installed on the outer side of the stirring shaft 101 in a ring shape. The stirring rack 103 is installed on the inner side of the stirring frame 102. The second stirring assembly includes stirring rods 201, scrapers 202, and sealing blocks 203. Multiple stirring rods 201 are installed on the bottom of the outer side of the stirring shaft 101 in an inclined manner. Scrapers 202 are installed on the outer ends of the stirring rods 201. The sealing blocks 203 are rotatably mounted on the bottom end of the stirring shaft 101.

[0027] like Figure 4 As shown, the mounting plate 8 is installed inside the second separation tank 3. A centrifugal separator 9 is rotatably mounted on the lower side of the mounting plate 8. A drive component for driving the centrifugal separator 9 to rotate is provided on the upper side of the mounting plate 8. The drive component is a forward and reverse motor. The area formed between the centrifugal separator 9 and the second separation tank 3 is a slag retention area. A baffle assembly is installed on the outer side of the second separation tank 3. The baffle assembly includes a mounting sleeve 301, a mounting bracket 302, a baffle plate 303, and a bolt 304. Two mounting sleeves 301 are installed on the outer side of the second separation tank 3 through two mounting blocks. The mounting bracket 302 is inserted into the lower side of the mounting sleeve 301. The baffle plate 303 is installed on the inner end of the mounting bracket 302. The bolt 304 passes through the outer side of the mounting sleeve 301. One end of the bolt 304 that passes through the mounting sleeve 301 is threaded onto the mounting bracket 302.

[0028] Working principle:

[0029] The workers connected an external water pump to a drain valve via a connecting pipe. Then, they started two reversible motors. The reversible motors on the lifting frame 7 drove the stirring shaft 101 to rotate. The stirring shaft 101 drove the stirring frame 102, stirring rack 103, and stirring rod 201 to rotate. The stirring rod 201 drove the scraper 202 to rotate. The reversible motors on the mounting plate 8 drove the centrifugal separator 9 to rotate. After the device was running, the workers added the coal-water mixture to the first separator 2 through the feed pipe. During the rotation, the stirring frame 102 and stirring rack 103 stirred and separated the coal-water mixture. The stirring rod 201 stirred the coal-water mixture falling to the bottom of the first separator 2. The scraper 202 scraped away the coal lumps stuck at the connection between the first separator 2 and the connecting pipe 4. During the stirring and separation process, coal slag and water entered the second separator 3 through the connecting pipe 4. Large coal lumps were intercepted inside the first separator 2. After the coal slag and water entered the second separator 3... The coal slag is blocked inside the slag retention area by the rotating centrifugal separator 9. Water enters the centrifugal separator 9 and is pumped out of the second separation tank 3 by an external water pump through the drain valve, achieving complete separation of coal and water. After separation, the electric push rod 6 is activated. The telescopic end of the electric push rod 6 extends and pushes the lifting frame 7 upward. The lifting frame 7 drives the stirring separation mechanism upward, thereby removing the blockage block 203 inside the stirring separation mechanism from the discharge port of the first separation tank 2. Large coal blocks inside the first separation tank 2 are discharged through the discharge port. The operator turns the bolt 304 counterclockwise to remove the bolt 304 from fixing the mounting sleeve 301 and the mounting bracket 302. After removal, the mounting bracket 302 is pulled out from inside the mounting sleeve 301. The mounting bracket 302 drives the baffle plate 303 downward, removing the baffle plate 303 from blocking the slag retention area. After removal, the operator cleans the slag inside the slag retention area, realizing the discharge of the separated large coal blocks and slag.

[0030] The above are merely preferred embodiments of the present utility model and are 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 included within the protection scope of the present utility model.
