On the other hand, affected by factors such as the long operation time of the impeller coal feeder, co-firing of sludge, and coal spillage, the coal accumulation on the coal feeding platform of the impeller coal feeder is serious and not easy to clean. Long-term coal and powder accumulation is likely to cause spontaneous combustion of pulverized coal, posing a fire risk. At the same time, it also has a certain impact on the daily inspection work of inspection personnel and safe and civilized production. Based on this, it is particularly important to solve the problem of coal accumulation in the impeller coal feeder. Utility Model Content

[0021] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] Before describing the various embodiments of the present application in detail, the technical concept of the present application will be briefly described first: Currently, the impeller coal feeder in use is prone to serious coal accumulation on the coal distribution platform. For this reason, the impeller coal feeder device provided by the present application is provided with a downwardly inclined coal dropping channel at the edge of the upper surface of the coal distribution platform, and the pulverized coal on the coal distribution platform is timely slipped onto the belt by using the coal dropping channel to avoid accumulation on the coal distribution platform. The specific principle of the impeller coal feeder device of the present application will be described below with more embodiments.

[0023] Specifically, as Figure 1 and Figure 2As shown, the impeller coal feeder equipment includes a coal feeding platform 10, vane claws 20, and a coal dropping channel 30. The coal feeding platform 10 is located above the belt 100. The vane claws 20 are installed on the upper surface of the coal feeding platform 10. The coal dropping channel 30 is arranged to slope downwards, and the head end of the coal dropping channel 30 is connected to the edge of the upper surface of the coal feeding platform 10, and the tail end of the coal dropping channel 30 extends above the belt 100. Since during operation, the vane claws 20 are likely to scatter some coal to the edge of the coal feeding platform 10, the scattered pulverized coal can be timely discharged through the coal dropping channel 30 to avoid large accumulation.

[0024] In one or more embodiments, as Figure 3 shown, the coal dropping channel 30 includes a bottom plate 31, a first side plate 32, and a second side plate 33. The first side plate 32 and the second side plate 33 are arranged on opposite sides of the bottom plate 31. Exemplarily, the first side plate 32 and the second side plate 33 are respectively welded to opposite sides of the bottom plate 31, and the head end of the coal dropping channel 30 is welded to the edge of the upper surface of the coal feeding platform 10.

[0025] Further, as Figure 4 shown, the impeller coal feeder equipment further includes a bearing box 40. The bearing box 40 is arranged on the side of the coal feeding platform 10 and above the belt 100. The bearing box 40 is provided with a coal dropping port 41, and the tail end of the coal dropping channel 30 is connected to the coal dropping port 41. Exemplarily, the side surface of the coal dropping port 41 includes a plurality of spliced ramp surfaces and a welding surface, and the welding surface is welded to the tail end of the coal dropping channel 30, which is beneficial for the pulverized coal to fall from the coal dropping port 41 to the belt 100.

[0026] In one or more embodiments, the impeller coal feeder equipment further includes a vertical channel 50. The vertical channel 50 vertically penetrates the coal feeding platform 10, and the top end of the vertical channel 50 is located on the upper surface of the coal feeding platform 10, and the bottom end of the vertical channel 50 extends above the belt 100. Exemplarily, the vertical channel 50 is closer to the center of the coal feeding platform 10 than the coal dropping channel 30. Through the vertical channel 50, the pulverized coal near the center of the coal feeding platform 10 can be discharged to the belt 100.

[0027] The impeller coal feeder equipment provided in this embodiment has the following effects:

[0028] The pulverized coal dropped on the coal feeding platform during the operation of the impeller coal feeder can be timely discharged, avoiding a large accumulation of pulverized coal on the coal feeding platform and reducing the risk of spontaneous combustion.

[0029] The specific implementation manners of the present application have been described in detail above. Although some embodiments have been shown and described, those skilled in the art should understand that without departing from the principles and spirits of the present application defined by the claims and their equivalents, these embodiments can be modified and improved, and these modifications and improvements should also be within the protection scope of the present application.
