[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, one embodiment of the utility model provides an automatic silt removal device for an underground sedimentation tank in a coal mine, comprising: a displacement mechanism 11, a submersible mud pump 12, a lifting mechanism 13 and a filtering mechanism 14; the displacement mechanism 11 is installed on the top wall of the tunnel above the underground sedimentation tank in the coal mine; the lifting mechanism 13 is installed on the displacement mechanism 11, and the displacement mechanism 11 can adjust the position of the lifting mechanism 13; the submersible mud pump 12 is arranged on the lifting mechanism 13, and the lifting mechanism 13 can adjust the height of the submersible mud pump 12; the filtering mechanism 14 is arranged next to the underground sedimentation tank in the coal mine, and the outlet end of the submersible mud pump 12 is connected to the inlet end of the filtering mechanism 14.

[0030] The automatic silt removal device provided in this embodiment is applied to an underground sedimentation tank in a coal mine. The coal mine has a tunnel, and the sedimentation tank is arranged in the tunnel. It includes a tank body and some auxiliary equipment. It is a well-known technology in the field, so it will not be described in detail here. The above-mentioned automatic silt removal device includes: a displacement mechanism 11, a submersible mud pump 12, a lifting mechanism 13 and a filtering mechanism 14. Among them, the displacement mechanism 11 is fixed on the top wall of the tunnel and is located above the sedimentation tank. The lifting mechanism 13 is installed on the displacement mechanism 11, and the submersible mud pump 12 is installed on the lifting mechanism 13. When in use, the lifting mechanism 13 moves on the displacement mechanism 11, thereby changing the position of the submersible mud pump 12 located on the lifting mechanism 13. The lifting mechanism 13 drives the submersible mud pump 12 to move, thereby changing the horizontal height of the submersible mud pump 12 and adjusting the depth of the submersible mud pump 12 immersed in the sedimentation tank. It should be noted that the displacement mechanism 11 mainly changes the horizontal position of the submersible mud pump 12, while the lifting mechanism 13 mainly changes the vertical position of the submersible mud pump 12. The displacement mechanism 11 and the lifting mechanism 13 adjust the position of the submersible mud pump 12, ensuring it remains below the mud level in the sedimentation tank. A filter mechanism 14 is located adjacent to the sedimentation tank, separating solid matter from water. Specifically, the outlet of the submersible mud pump 12 is connected to the inlet of the filter mechanism 14. Under the action of the submersible mud pump 12, the mud in the sedimentation tank enters the filter mechanism 14 for filtration, achieving mud-water separation.

[0031] The automatic desilting device for underground coal mine sedimentation tanks provided in this embodiment utilizes a submersible mud pump 12 in conjunction with a filtration mechanism 14 to process fine particles, such as mud, within the sedimentation tank, thereby reducing the labor intensity of manual excavation. Furthermore, the displacement mechanism 11 and the lifting mechanism 13 work together to ensure that the submersible mud pump 12 is always below the mud level within the sedimentation tank, enabling real-time desilting. Experimental calculations have shown that the desilting frequency of the sedimentation tank can be extended from once a year to once every five years. Compared to existing technologies, this reduces labor intensity and enables real-time desilting.

[0032] The automatic desilting device for a coal mine underground sedimentation tank provided by the embodiment of the utility model is as follows: Figure 1 As shown, the displacement mechanism 11 includes a slide rail, which is installed on the top wall of the tunnel above the sedimentation tank in the coal mine through an anchor rod.

[0033] In this embodiment, the displacement mechanism 11 utilizes a slide rail, which has a simple structure and low cost. The slide rail is mounted on the top wall of the tunnel via anchor rods, which provides enhanced stability. Alternatively, in this embodiment, the slide rail may be a T-shaped cross-section or may be provided with a T-slot.

[0034] It is understandable that, in this embodiment, the displacement mechanism 11 may also adopt a structure such as a crown block, which can also achieve the purpose of changing the horizontal position of the submersible mud pump 12 in this embodiment.

[0035] The automatic desilting device for a coal mine underground sedimentation tank provided by the embodiment of the utility model is as follows: Figure 1 As shown, the lifting mechanism 13 is an electric hoist; the electric hoist is installed on the slide rail through its own running car, and the submersible mud pump 12 is installed on the hook of the electric hoist.

[0036] In this embodiment, the lifting mechanism 13 is an electric hoist. This type of hoist is characterized by its compact size, light weight, simple operation, and ease of use. The hoist has a hook, and the submersible mud pump 12 is suspended from the hook. The hoist also has a running carriage, which allows the hoist to be mounted on a slide rail, enabling it to move along the rail.

[0037] It is understandable that, in this embodiment, the lifting mechanism 13 may also be a winch, which can also achieve the purpose of driving the submersible mud pump 12 to move up and down in this embodiment.

[0038] The automatic desilting device for a coal mine underground sedimentation tank provided by the embodiment of the utility model is as follows: Figure 1 As shown, the submersible mud pump 12 is provided with a lifting ring, and the submersible mud pump 12 is hung on the hook of the electric hoist through the lifting ring.

[0039] In this embodiment, a lifting ring is provided on the submersible mud pump 12, and the submersible mud pump 12 is set on the hook of the electric hoist through the lifting ring. The lifting ring is connected to the hook, which can play a certain buffering role and play a certain protective role for the electric hoist and the submersible mud pump 12.

[0040] The automatic desilting device for a coal mine underground sedimentation tank provided by the embodiment of the utility model is as follows: Figure 1 As shown, it also includes a concentration detection device 15 and a rubber hose 16; one end of the rubber hose 16 is connected to the outlet end of the submersible mud pump 12, and the other end is connected to the feed end of the filtering mechanism 14 through the concentration detection device 15.

[0041] The automatic desilting device for an underground sedimentation tank in a coal mine provided in this embodiment is further provided with a concentration detection device 15. The concentration detection device 15 is a concentration detector for detecting the concentration of solid particles in the mud in the sedimentation tank, thereby facilitating the setting of operating parameters of the filter mechanism 14. The concentration detection device 15 is arranged between the submersible mud pump 12 and the filter mechanism 14. Specifically, the outlet end of the submersible mud pump 12 is connected to a rubber hose 16. The end of the rubber hose 16 facing away from the submersible mud pump 12 is connected to the feed end of the concentration detection device 15. The discharge end of the concentration detection device 15 is connected to the feed end of the filter mechanism 14 through a pipeline. Since the position of the submersible mud pump 12 often changes, the rubber hose 16 is used in this embodiment to connect the submersible mud pump 12 and the concentration detection device 15, which has greater adaptability.

[0042] The automatic desilting device for a coal mine underground sedimentation tank provided by the embodiment of the utility model is as follows: Figure 1 As shown, a float is provided on the rubber hose 16 .

[0043] In this embodiment, a float is provided on the rubber hose 16 , and the rubber hose 16 can float on the surface of the mud under the action of the float, thereby preventing the rubber hose 16 from being squeezed and affecting its conveying function.

[0044] The automatic desilting device for a coal mine underground sedimentation tank provided by the embodiment of the utility model is as follows: Figure 1 As shown, a pressure sensor is provided at the lower end of the submersible mud pump 12 .

[0045] In this embodiment, a pressure sensor is further provided at the lower end of the submersible mud pump 12. The pressure sensor is used to monitor pressure information, thereby sounding an alarm when the submersible mud pump 12 hits the bottom, thereby preventing the submersible mud pump 12 from hitting the bottom.

[0046] The automatic desilting device for a coal mine underground sedimentation tank provided by the embodiment of the utility model is as follows: Figure 1 As shown, the submersible mud pump 12 is further provided with a stirring mechanism 121 .

[0047] In this embodiment, the submersible mud pump 12 is also provided with a stirring mechanism 121 for stirring the mud in the sedimentation tank. Under the action of the stirring mechanism 121, the mud in the sedimentation tank can be made uniform, preventing the submersible mud pump 12 from being blocked during use, and ensuring that production can proceed normally.

[0048] In this embodiment, the stirring mechanism 121 includes blades, which are positioned near or directly integrated into the submersible mud pump 12. The blades stir the mud, preventing solid particle settling and maintaining the fluidity and uniformity of the mud. The shape, number, and layout of the stirring blades depend on the specific application requirements.

[0049] The automatic desilting device for a coal mine underground sedimentation tank provided by the embodiment of the utility model is as follows: Figure 1 As shown, the filtering mechanism 14 is a filter press, which has a better filtering effect on mud.
