Description

Technical Field

[0001] The utility model relates to a dust suppression device, in particular to a circulating flow relief dust suppression device for a transfer station, and belongs to the technical field of dust suppression devices. Background Art

[0002] Dust is one of the five major natural disasters in coal mines and has always been the focus of prevention and control in coal mines. The existing coal transportation is mostly carried out by belt conveyor. During the belt conveyor, the coal dust in the tunnel is relatively large, especially when the belt conveyor is turned on, the coal dust is flying particularly seriously, seriously polluting the underground air flow. Therefore, dust suppression devices are usually used to suppress the flying of coal dust;

[0003] Existing dust suppression devices mostly use traditional transfer point spraying. By utilizing the Coanda effect, liquid is sprayed onto a curved surface, allowing it to flow along the shape of the curved surface and form a fine spray, thereby suppressing coal dust. However, at the moment when the belt conveyor is started, the inertia of the coal mine and the vibration of mechanical equipment cause the coal dust to fly particularly seriously. Traditional transfer point spraying is difficult to suppress the flying of coal dust at this time due to its slow water mist spraying speed and relatively uniform spraying amount. For this reason, a transfer station circulating discharge dust suppression device is proposed. Utility Model Content

[0027] In one embodiment, the outer wall of the unpowered electrostatic dust suppression device 14 is installed inside the dustproof shell 30, and the outer wall of the adjustable tail sealing box 17 is installed inside the dustproof shell 30. Through the setting of the dustproof shell 30, the unpowered electrostatic dust suppression device 14 and the adjustable tail sealing box 17 are fixed. The unpowered electrostatic dust suppression device 14 absorbs and separates the trace dust generated by the disturbance of the first coal dust diversion device 15 and the second coal dust diversion device 16 by electrostatic adsorption, thereby ensuring that no dust overflows at the outlet of the material guide trough 25; through the setting of the adjustable tail sealing box 17, there is a good sliding sealing measure, which effectively blocks the dust gas channel and prevents dust overflow at the tail end of the material guide trough 25.

[0028] In one embodiment, one side of the first coal dust diversion device 15 is fixedly connected to the inner top wall of the dustproof shell 30, and one side of the second coal dust diversion device 16 is fixedly connected to the inner top wall of the dustproof shell 30.

[0029] In one embodiment, the main body component 201 includes a mounting plate 20, a conveying belt 21, a first manhole door 22, a second manhole door 23, a feeding port 24 and a material guide trough 25; the bottom of the dustproof shell 30 is fixedly connected to the top of the mounting plate 20, and the conveying belt 21 is installed on one side of the mounting plate 20. Through the setting of the mounting plate 20, the dustproof shell 30 and the conveying belt 21 are fixed.
