Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a clinker conveyor device used as an ash processing device for a coal-fired boiler.

[Conventional technology]

FIG. 6 shows a side view of a conventional clinker conveyor, and FIG. 7 shows a sectional view taken along line XX of FIG. In the figure, 1 is a clinker conveyor main body, 2 is a scraper built in the main body, 3
Is a boiler, 4 is a seal plate provided at the bottom of the boiler, 5 is water, and 6 is an ash discharge port provided at the end of the main body 1.

In this device, the main body 1 is filled with water 5 so that the seal plate 4 is attached. By sprinkling the water 5 with the seal plate 4, the atmosphere inside and outside the boiler 3 is shielded and sealed. That is, it becomes a watertight seal. As the boiler 3 is coal-fired, ash falls. This ash is discharged to the outside from the discharge port 6 by the scraper 2. The clinker conveyor 1 is of a stationary type.

In this method, since the clinker conveyor 1 is a stationary type and is used after being filled with water, when the clinker conveyor 1 fails, it is necessary to stop the operation of the boiler 3 and overhaul it. This reduces the operating efficiency of the boiler. Therefore, a clinker conveyor that can be maintained without stopping the operation of the boiler is required.

In order to solve the above-mentioned drawbacks of the prior art, the applicant of the present application has previously filed a utility model registration application No. 122700 in 1988.
Filed an improved clinker conveyor system. 2 to 5 relate to the above-mentioned application of the applicant. FIG. 3 is a perspective view of the clinker conveyor of the same application, and FIG.
The figure is a side view of the upper central part of the device of FIG. In the figure, 11 and 21 are the bodies of a pair of clinker conveyors which are connected side by side to switch and use the clinker conveyor, 11a.
And 21a is a side casing of each clinker conveyor body, 12 is a partition plate provided at the boundary of the same pair of bodies, 13a and 13b are support shafts provided at both ends of the partition plate 12, and 14 is on the clinker conveyor side. The support shaft is rotatably held by a bearing provided. 15 is a gear provided on the support shaft 13a, 16 is a worm gear meshing with the gear 15,
17 is a motor that drives the worm gear. Motor 1
The partition plate 12 can be rotated 90 degrees in one direction by the drive mechanism including the worm gear 16, the worm gear 16, and the gear 15. Reference numeral 18 denotes a bellows-shaped member provided at both ends of the partition plate 12 for preventing water leakage.

FIG. 2 is a perspective view showing a connecting portion of the bellows-shaped member 18. In the figure, 22 is the clinker conveyor main body 11 and 21.
The fixing plate is attached so as to be orthogonal to the side plate at the boundary portion with, and 12 is the above-mentioned partition plate, and the bellows-shaped member 18 is attached between the fixed plate 22 and the partition plate 12 at the ends thereof. ing. When the partition plate 12 rotates, the bellows-shaped member extends and absorbs the amount of movement thereof.

FIG. 5 is a sectional view taken along line YY of FIG. This device has an advantage that it is not necessary to stop the operation of the boiler when one clinker conveyor 11 fails and the other clinker conveyor 21 is used by switching.
In the case of the above switching, after preliminarily filling the spare clinker conveyor 21 with water, the partition plate 12 is rotated, and after switching to the spare clinker conveyor 21, the partition plate is reversely rotated again to the original state. The operation is performed.

[Problems to be solved by the device]

In the apparatus described above, when the switching operation shown in FIG. 5 is performed, the bellows-shaped member 18 is not folded along the fold line as shown in FIG. May be. This phenomenon is likely to occur when a water level difference ΔH occurs between the clinker conveyor 11 and the clinker conveyor 21 shown in FIG. That is, when the water head having the water level difference ΔH is applied to the bellows-shaped member, the bellows-shaped member easily bends to cause the protrusion E. This causes damage to the bellows-shaped member in such a state, resulting in incompatibility.

The present invention is intended to solve the above-mentioned drawbacks of the clinker conveyor previously filed by the applicant, and to provide an improved clinker conveyor device so that the bellows-shaped member does not protrude.

[Means for Solving the Problems]

The present invention is to solve the above problems, and a plurality of clinker conveyors whose main bodies are connected in parallel below a coal-fired boiler, and a fixing plate which is connected to the main body at the boundary of the plurality of clinker conveyors. A clinker conveyor device provided with a partition plate rotatably provided in proximity to the fixed plate, and a bellows-like member for coupling the fixed plate and the partition plate between their opposing ends. A fan-shaped plate attached to the fixed plate, a fan-shaped plate attached to the partition plate and having a tooth profile on the outer peripheral surface, a pinion gear meshing with the tooth profile of the fan-shaped plate, and a drive motor for driving the pinion. The present invention relates to a clinker conveyor device, characterized in that the two fan-shaped plates are provided at positions sandwiching the bellows-shaped member.

[Action]

In the clinker conveyor device of the present invention, since the bellows-shaped member is sandwiched by the two fan-shaped plates, the protrusion is prevented.

Further, the partition plate is driven by the drive motor and the pinion gear through the tooth profile on the outer peripheral surface of the fan-shaped plate attached thereto.

〔Example〕

FIG. 1 shows a partial perspective view of an embodiment of the present invention. In the figure, 23 is a fan-shaped plate attached to the fixed plate 22, and 24 is a fan-shaped plate attached to the partition plate 12 having a tooth shape on the outer peripheral surface. In addition, 25 is a small gear that meshes with the tooth profile of the fan-shaped plate,
Reference numeral 26 is a motor for driving the small gear 25, and 27 is a support base of the motor, which is fixed to a side plate of the clinker conveyor. In this device, the fan-shaped plate 24 is driven by the motor 26, and the partition plate 12 rotates with this, so that the partition plate drive composed of the motor 17, the worm gear 16, and the gear 15 provided in the device of the previous application is driven. No mechanism is provided. The parts other than the above are the same as those of the applicant's previous application, and therefore the description thereof will be omitted.

Since the clinker conveyor of this embodiment is constructed as described above, the protrusion of the bellows-shaped member 18 shown in FIG. 2 is prevented by the fan-shaped plates 23 and 24 attached to the fixing plate and the partition plate. can do. Furthermore, the fan-shaped plate attached to the partition plate is provided with teeth on the outer peripheral surface to drive the partition plate through this, so the fan-shaped plate attached to this partition plate has two functions. The structure is simple as a whole.

[Effect of device]

In the clinker conveyor device of the present invention, a fan-shaped plate attached to a fixed plate, a fan-shaped plate having a tooth profile on an outer peripheral surface attached to a partition plate, a pinion gear meshing with the tooth profile of the fan-shaped plate, and the pinion gear are driven. Since a drive motor is provided and the two fan-shaped plates are provided at a position sandwiching the bellows-shaped member, it is possible to prevent the bellows-shaped member from protruding and the damage to the members. Further, since the fan-shaped plate attached to the partition plate is driven, the structure is simplified as a whole.
