Definitions
- Patent Document 2 describes a technology for removing ash in the vicinity of the discharge opening with a cutter in order to enable the continuous operation of the ash discharger.
- a special mechanism such as the cutter needs to be provided, which increases costs.
- An object of the present invention is to provide an ash discharger that can facilitate the continuous operation of the ash discharger at low costs.
- the scraper in the ash discharger according to the second aspect, includes: a scraper body that pushes the ash; and an auxiliary scraper connected to the scraper body, the auxiliary scraper guiding return ash of the ash to the first communicating portion.
- the ash cooling tank 3 is a tank connected to the lower side of the ash introduction opening 2 to cool the ash A2 introduced through the ash introduction opening 2.
- the bottom surface 10 of the ash cooling tank 3 includes a second inclined surface 12 that gradually becomes higher from directly below the ash introduction opening 2 in a second direction D2 that is opposite the first direction D1.
- the mechanisms for pushing the ash A2, such as the scraper 4 and the driving unit 5, are disposed above the second inclined surface 12.
- the scraper body 15 is disposed such that a tip thereof contacts the bottom surface 10 of the ash cooling tank 3 in a width direction "WD" (horizontal direction orthogonal to the first direction D1, see FIG. 2 ).
- the scraper body 15 pushes the ash A2 toward the downstream side by pivoting the pivoting arm 14 in a first rotating direction R1. Pivoting of the pivoting arm 14 in a second rotating direction R2 opposite to the first rotating direction R1 retracts the tip of the scraper body 15 in the second direction D2.
- the float tank 8 is provided with a liquid level gauge 24 for measuring the height of the liquid surface "W” in the float tank 8.
- the liquid level gauge 24 is electrically connected to the control device 9. The height of the liquid surface "W” measured by the liquid level gauge 24 is transmitted to the control device 9.
- the ash discharger 1 includes a first liquid supply device 27 that supplies liquid to the vicinity of the discharge opening 6. Specifically, the first liquid supply device 27 sprays the liquid onto the ash A2a deposited in the drainage region "R" of the ash cooling tank 3.
- the first liquid supply device 27 includes a circulation liquid injection nozzle 28 disposed above the discharge opening 6, a circulation liquid line 29 that connects the circulation liquid injection nozzle 28 to the sedimentation tank 23, and a circulation pump 30 provided in the circulation liquid line 29 to circulate the liquid in the sedimentation tank 23 to the circulation liquid injection nozzle 28. Since the liquid stored in the sedimentation tank 23 is the liquid flowing into the overflow liquid receiver 21, the first liquid supply device 27 substantially circulates the liquid inside the float tank 8 to the circulation liquid injection nozzle 28. Liquid may also be supplied to the first liquid supply device 27 from other sources.
- return ash A3 moves on the second inclined surface 12 on the second direction D2 side with respect to the scraper 4.
- the return ash A3 is ash that, when the scraper 4 retracts, enters the second direction D2 side with respect to the scraper 4 through a gap or the like between the scraper 4 and the bottom surface 10.
- the return ash A3 is introduced into the float tank 8 via the communication pipe 7.
- the return ash A3 deposited in the float tank 8 can be discharged as appropriate via the float tank discharge pipe 17 by opening the float tank valve 18.
- the ash cooling tank 3 and the float tank 8 in the modification communicate with each other via an opening 40 (second communicating portion) formed in a partition wall 39 partitioning the ash cooling tank 3 and the float tank 8, in addition to the communication pipe 7.
- the opening 40 is formed to connect the liquid surface "W” in the ash cooling tank 3 to the liquid surface "W” in the float tank 8.
- the opening 40 is formed such that a lower end 40a of the opening 40 is lower than the liquid surface "W", and an upper end 40b is higher than the liquid surface "W”.
- the first liquid supply device 27 is configured to circulate the liquid in the sedimentation tank 23 (float tank 8) to the circulation liquid injection nozzle 28, but the present invention is not limited thereto.
- it may be a first liquid supply device 27B that circulates the liquid stored in the ash cooling tank 3 to the circulation liquid injection nozzle 28.
- the first liquid supply device 27B is controlled by the control device 9.
