Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to a high-efficiency coal-water separation device for coal mines. Background Technology

[0002] Coal-water separation equipment is mainly used to separate coal from a coal-water mixture. Its purpose is to improve coal utilization, reduce water pollution, and improve the coal production environment.

[0003] CN214270405U discloses a coal slurry water separation device, including a sedimentation tank, a mixing tank, and a filter tank. A first drive motor is fixedly installed on one side of the bottom of the sedimentation tank, a cleaning device is fixedly installed on one side of the top of the mixing tank, and a first filter screen is fixedly installed at the bottom of the mixing tank. Two first chutes and a second chutes are respectively opened on one side of the filter tank. A second filter screen is slidably connected between the two first chutes, and a third filter screen is slidably connected between the two second chutes. The beneficial effects of this utility model are: the sedimentation tank can play a good role in sedimentation and storage of coal slurry water; the second and third filter screens set inside the collection tank can better filter the separated coal slurry water; and the rubber plug on the water outlet can play a sealing role and prevent the water outlet from being blocked by external materials during operation.

[0004] However, in the actual operation of this type of separation equipment, after the coal water passes through the filter screen, coal particles and some impurities may be intercepted on the surface of the filter screen. However, the device does not have a collection mechanism for the intercepted substances, which may require manual collection. This process is not only time-consuming, but also reduces the separation efficiency of the device and poses a risk of clogging. Therefore, it needs to be improved. To this end, a high-efficiency coal-water separation device for coal mines is proposed. Summary of the Invention

[0036] Example 2

[0037] A high-efficiency coal-water separation device for coal mines, wherein the sealing gasket 15 is made of rubber. The sealing gasket 15 made of rubber has excellent sealing effect, thereby improving the airtightness of the separation chamber 1.

[0038] In this embodiment, specifically: threaded rod a8 and threaded rod b22 are rotatably connected in the separation chamber 1. When the motor 7 is started, it drives the threaded rod a8 to rotate. At the same time, under the connection between pulley a19 and pulley b20, the threaded rod b22 will rotate.

[0039] In this embodiment, specifically: the scraper 10 is in contact with the filter plate 4, and during the movement of the frame plate 9, the scraper 10 will scrape the coal particles intercepted on the surface of the filter plate 4.

[0040] In this embodiment, specifically: the flushing plate 24 is slidably connected in the separation chamber 1. When the flushing plate 24 is working, it will drive water to spray out and impact the back of the filter plate 4.

[0043] In operation, this invention works as follows: First, molten coal is injected into the separation chamber 1 through the feed pipe 2. Then, the pressure pump 3 is started to increase the pressure inside the separation chamber 1. Under the pressure, the efficiency of the molten coal passing through the filter plate 4 is accelerated. At this time, the filter plate 4 will perform coarse filtration of the molten coal and intercept coal particles. When it is necessary to collect the coal particles, the motor 7 is started and the threaded rod a8 is driven to rotate. At this time, under the action of the thread, the frame plate 9 can be driven to slide along the separation chamber 1. Under the action of the spring 11, the scraper 10 and the filter plate 4 can always be kept in contact. Then, during the movement of the frame plate 9, the surface of the filter plate 4 will be... The coal particles intercepted on the surface are scraped, and at the same time, the connection between pulleys a19 and b20 drives the threaded rod b22 to rotate. At this time, the threaded rod drives the moving plate 23 and the flushing plate 24 to slide together. At this time, the water pump 18 is started and water is drawn out of the water tank 16 through the water pipe 17 and pressurized. Finally, the water is injected into the flushing plate 24 through the water pipe 17. Under the action of the flushing plate 24, the water is sprayed out and acts on the back of the filter plate 4. Then, under the impact, the coal particles on the inside of the filter plate 4 are flushed out, thereby improving the cleaning effect of the filter plate 4 and reducing the occurrence of clogging.
