Description

  The present invention relates to a transfer device suitable for transferring biomass waste such as wood waste such as wood chips, livestock organic waste, living organic waste, and organic industrial waste.

In recent years, the effective use of biomass waste, such as the effective use of forest resources and the effective use of livestock waste, has been studied under the de-oiling of energy sources.
For example, Patent Document 1 proposes a technique for generating fuel gas from organic waste.
In this case, it is necessary to stably convey and supply waste to an apparatus such as a fuel gas generator.
However, for example, wood chips as shown in FIG. 7 and cow dung discharged as livestock waste are easily entangled with each other, for example, in conventional screw screw machines for resin pellets, the conveying material is screw teeth. It was clogged in between, and stable conveyance was difficult.

JP 2006-299011 A

  The present invention is indispensable for the effective use of organic waste such as biomass waste, and an object of the present invention is to provide a transport device that prevents clogging of materials.

  A transfer device according to the present invention includes a storage tank for a transfer material and a transfer mechanism unit for transferring the transfer material supplied from the storage tank. The transfer mechanism unit includes a transfer cylinder and a transfer chain built in the transfer cylinder. The conveying chain has a conveying claw protruding toward the bottom or lower inclined part of the conveying cylinder, and the conveying claw pulls up the conveying material along the bottom or lower inclined part of the conveying cylinder. It is what is conveyed.

Here, the transport cylinder transports the material toward the organic waste utilization device, and has a material input port and a transport port.
Although it is assumed that the material is transported in the horizontal direction and the material is transported upward, material clogging is likely to occur when the material is transported vertically or obliquely upward.
Therefore, in the present invention, the transport claw is moved upward along the inclined portion on the lower side of the transport cylinder so that the material is sequentially transported by being picked up or lifted by the transport claw. There is a feature.
In this way, it is possible to prevent the material from being directly entangled with the chain, and the chain becomes slack after the conveying chain pulls up the material and reverses in the reverse direction from the material outlet, so that there is less material clogging. Become.

Therefore, the conveyance cylinder may have a horizontal portion and an inclined portion extending obliquely upward, and supply a conveyance material to an opening provided in the horizontal portion.
In addition, in order to stably take out the transport material stored in the storage tank, the storage tank may have a transport material transfer conveyor at the bottom and a transport material supply port at the lower side of the side wall on the conveyor transfer side of the storage tank. Good.

  In the present invention, the conveyance chain is built in the conveyance cylinder, and the conveyance claw attached to the conveyance chain is lifted upward along the lower slope portion of the conveyance cylinder. This effectively prevents the chain from being clogged with transport material.

The structural example of a conveyance mechanism part is shown. (A) is a general view, (b) is an enlarged view of the chain portion, and (c) is a top view of the carry-out cylinder. The structural example of a storage tank is shown. (A) is a front view, (b) is a plan view, and (c) is a side view. The positional relationship of the material supply port of a storage tank and the material input port of a conveyance cylinder is shown. An example of supplying organic waste as fuel to a biomass fuel boiler is shown. An example of the structure of a biomass fuel boiler is shown. The principle diagram of a biomass fuel boiler is shown. An example of a wood chip is shown.

An example of the structure of a transport apparatus according to the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the transport device includes a storage tank 10 and a transport mechanism unit 20 that transports organic waste (hereinafter referred to as a material) thrown from the supply port of the storage tank obliquely upward.

As shown in FIG. 2, the storage tank 10 has a transfer conveyor 11 stretched along the bottom, and the transfer conveyor is driven and driven by a reduction gear 13 connected to a gear motor 12 and a driven shaft 14. It is stretched between the shaft 15.
The conveyor 11 adjusts the tension by the tension adjusting tool 16.

The material stored in the storage tank is input little by little from the supply port 17 to the input port 21 a of the transport cylinder 21 by the rotation of the conveyor 11.
Since materials such as wood chips are easily entangled with each other and easily lumped even when the material is transferred by the conveyor 11, it is preferable to provide protrusions on the surface of the conveyor 11 and scrape it toward the supply port 17.

The transport mechanism 20 has a transport chain 23 built in a transport cylinder 21 having a cylindrical cross section.
The transport cylinder 21 includes a horizontal portion 21b and an inclined portion 21c, and has an opening 21a for feeding material into the horizontal portion 21b as shown in FIG.
The conveying chain 23 is stretched between a driving sprocket 25a connected to a driving gear motor 24 provided on the upper side of the conveying cylinder 21 and a driven sprocket 25c provided on the rear end side of the horizontal portion. A conveying chain 23 is stretched at a corner portion between the inclined portion 21c and a bent sprocket 25b.
The transport chain 23 includes a plurality of chain pieces rotatably connected to each other, and a transport claw 23a is attached at regular intervals, and the lower transport claw 23a is a lower slope portion of the transport cylinder 21. 1 and is rotated so as to be pulled up as indicated by an arrow in FIG.
Although there is no particular limitation on the shape of the transport claw, as shown in an enlarged view in FIG. It is an example with bolts.
As a result, the material is pulled up so as to store the material between the lower side of the transport chain 23 and the inner side surface of the lower inclined portion of the transport cylinder 21.
Accordingly, the lower side of the transport chain 23 in FIG. 1 is stretched, and the upper reversal chain portion is slack.
In this way, since the conveying claw 23a pulls the material inside the conveying cylinder 21 along the inclined surface, the material is prevented from being caught in the chain piece, and the chain piece is loosened at the portion of the reverse side chain, so the carrying-out cylinder 22 The material that has not fallen down will fall when the chain piece loosens.
The amount of slack can be adjusted by the chain tension adjusting tool 26.
At the upper end of the transport cylinder 21, there is a carry-out cylinder 22 that opens in a diagonally downward direction, and the material is carried out from the carry-out cylinder 22.

Next, a usage example of the transport device according to the present invention will be described.
FIG. 4 shows an example in which organic waste is supplied as fuel to the biomass fuel boiler A installed in the greenhouse B.
The biomass fuel boiler A shows an external view in FIG. 5 and a principle diagram in FIG.
The fuel input from the fuel inlet 1 is gasified and carbonized in the primary combustion section 2, and unburned gas and charcoal are combusted in the secondary combustion section 3.
Air necessary for combustion is supplied by the intake fan 4, and hot air is obtained by blowing air from the blower fan 7 to the heat exchanging unit 6, and the inside of the vinyl house is warmed.
The exhaust gas after combustion is forcibly exhausted from the exhaust cylinder 9a by the exhaust fan 8.
In an emergency, it is exhausted from the combustion furnace to the outside through the natural exhaust pipe 5.
