Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a chain flight conveyor that transfers powder and granular materials using an endless chain conveyor disposed within a curved transfer pipe.

[Conventional technology]

Conventional chain-type flight conveyors that convey powder and granules such as grains from below to above are shown in Figures 3 to 5.
As shown in the figure, the conveying pipe 1 has a lower horizontal part 2, a curved part 3, a vertical part 4, a curved part 5, and an upper horizontal part 6, which are successively connected to each other. A discharge port 8 is provided in the upper horizontal part 6, and a pair of left and right chain sprockets 9, 10 are provided at the ends of the lower horizontal part 2 and the upper horizontal part 6, respectively, extending from the lower horizontal part 2 to the upper horizontal part. Partition plate 1 in the longitudinal direction
1, sandwiching the left and right upper and lower surfaces of the partition plate 11,
A pair of endless chains 12 are arranged and suspended on chain sprockets 9 and 10.

Between the pair of chains 12, 12, the base ends of a large number of conveyor vanes 13 are attached at regular intervals. Further, a quantitative supply feeder 14 is provided above the supply port 7.

When a predetermined amount of powder and granular material is supplied from the constant supply feeder 14 through the supply port 7 onto the partition plate 11 of the lower horizontal section 2, it is sequentially transferred to the right in FIG. Partition plate 1 of horizontal section 2
It falls from the right end of 1 onto the lower surface of the lower horizontal part 2. The fallen powder is conveyed by the conveying blades 13 that have been rotated by the chain sprocket 9, passing through the curved part 3, the vertical part 4, the curved part 5, and the upper horizontal part 6 to the discharge port 8.
more excreted.

[Problem that the invention attempts to solve]

However, in the conveyance process, the powder and granules supplied from the supply port 7 are
In addition, between the conveying blades 13, 13, the upper part of the lower horizontal part 2, and the partition plate 1,
Since approximately the same amount is supplied as the volume defined by the upper surface of 1, the volume becomes larger when passing through the curved section 3 where the tips of the adjacent conveying blades 13, 13 are opened, but at the curved section 5, becomes smaller. Therefore, in the curved portion 5, the powder and granules are transferred to the adjacent conveying blade 1.
3 and 13, but if the powder exceeds a certain level, it will not be compressed, and accidents have occurred in which the conveying blades 13 are damaged by the compressed powder.

Therefore, an object of the present invention is to provide a chain-type flight conveyor in which the conveying blades do not break even when the conveying blades pass through a curved part while conveying powder or granular material.

[Means for solving problems]

Therefore, the present invention provides a partition plate that divides the inside of the pipe into two along the longitudinal direction in a conveying pipe that has a supply port at the bottom and a discharge port at the top, and these are connected via a curved pipe section. In a chain-type flight conveyor in which a pair of endless chains that are driven along the upper and lower surfaces of the plate are arranged on the left and right sides of a partition plate, and the base ends of an appropriate number of conveyor blades are installed between the endless chains, the conveyor side of the conveyor blade is A pair of regulating plates are provided projecting in the conveying direction from the tip of the conveying blade to an intermediate position with a predetermined interval between both regulating plates and between the regulating plate and the end of the conveying blade, and The opening is substantially the same as the distance between the pair of regulating plates.

[Effect]

By configuring as above, the granular material is defined from the supply port between the pair of regulating plates, between the adjacent conveying blades, the upper surface of the lower horizontal part, the upper surface of the partition plate, and between the pair of regulating plates. The volume is supplied, and it spreads from the bottom of the regulation plate to the left and right of the partition plate, and becomes approximately half the volume defined by the space between adjacent conveying blades, the top surface of the partition plate, and the top surface of the lower horizontal part, and forms a curved part. Even if the distance between adjacent conveyor blades becomes narrow, the blades will not be damaged by the powder or granules.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. A pair of left and right regulating plates 15, 1 are provided on the conveying side of the conventional conveying blade 13 from the tip to the intermediate position.
5 is provided protruding in the conveying direction.

Further, the left and right opening width W of the supply port 16 is approximately the same as the interval between the pair of regulating plates 15, 15.

Therefore, the powder A is supplied from the supply port 15 between the regulating plates 15, 15 of the conveying blades 13, 13 which are continuously operated in the endless chains 12, 12,
It spreads over the entire upper surface of the partition plate 11 from the lower part of the regulating plates 15, 15, is conveyed on the partition plate 11 while being pushed by the base end side of the conveying blade 13, and is spread below the end of the partition plate 11 in the lower horizontal part 2. It falls onto the lower surface of the horizontal section 2, is rotated by the chain sprocket 9, and is transferred to the conveyor blade 1.
3 and 13, and is discharged from the discharge port 8 through the curved section 3, the vertical section 4, the curved section 5, and the upper horizontal section 6 while being pushed by the tip side of the conveying blade 13.

At this time, also in the curved part 5, the conveying blades 13,
The amount of powder A between the conveyor blades 13 and 13 is approximately half that of the conventional one, so even if the distance between the conveyor blades 13 and 13 becomes narrow at the tip, the conveyor blades 13 and 13 at the curved portion 6
13, the lower surface of the curved portion 6, and the partition plate 11, the transport blade 13 is not damaged.

[Effect of idea]

As described above, the present invention uses powder conveyor blades,
A pair of regulating plates was provided from the tip side to the intermediate position with a predetermined interval between both regulating plates and between the regulating plate and the end on the conveying blade side, and the supply port was made approximately the same width as the width between the regulating plates. Therefore, the amount of powder and granular material to be supplied is limited, and since it spreads over the partition plate from the bottom of the regulating plate, the amount of powder and granular material supplied between the transport blades is limited by the transport blades, partition plate, and transport pipe. Even if the space between the conveying blades becomes narrower at the curved part due to the smaller capacity than the capacity of the conveying blades, the conveying blades will not be damaged by the powder or granules. Since they are the same, it is possible to limit the amount of powder and granular material to be supplied without providing a quantitative feeder at the supply port.
