[0002] The ash collecting auger below the bag dust collector adopts a U-shaped, central axis auger for conveying. The material feeding and discharging adopts the method of feeding on both sides and discharging in the middle. The effective length of the auger is 8500mm. The longer conveying distance results in a longer central axis.

[0003] When the auger is running, the middle part of the center shaft shifts to one side, causing serious wear near the middle discharge port and generating a lot of friction noise. The reason is that the auger shaft is too long and the conveyed material has high temperature, which increases the deflection of the center shaft. When running, the middle position of the center shaft (discharge position) is subject to the reaction force of the conveyed material, causing the center shaft to shift to one side, causing friction between the auger blades and the auger wall, resulting in serious wear at the friction part and friction noise. Utility Model Content

[0007] Preferably, the labyrinth seal is composed of a labyrinth seal dynamic ring and a labyrinth seal static ring, the fitting parts of the labyrinth seal dynamic ring and the labyrinth seal static ring are plugged into each other, the labyrinth seal dynamic ring is fixedly connected to the outer walls of the central axis of the auger, and the labyrinth seal static ring is fixedly connected to the inner walls of both sides of the intermediate bearing seat.

[0008] Preferably, the sliding bearing is composed of a sliding bearing inner ring and a sliding bearing outer ring, the fitting parts of the sliding bearing inner ring and the sliding bearing outer ring are slidingly connected, the sliding bearing inner ring is fixedly connected to the center of the outer wall of the central axis of the auger, and the sliding bearing outer ring is fixedly connected to the center of the inner wall of the intermediate bearing seat.

[0010] Preferably, the intermediate bearing seat adopts an upper and lower half structure and is fixed by bolts.

[0011] The utility model proposes an ash conveying device with an additional intermediate hanger bearing, which has the following beneficial effects:
