Description of the Related Art Conventionally, in the case of collecting and transporting powder particles falling over a wide range, an air transport pipe having a notched upper half is arranged below the hopper and filled in the hopper. There are those that transport transported goods (Actual Kai 51-5195).
Since these are premised on high-pressure, high-concentration plug transport, they require equipment, controls, etc. for intermittent operation of high-pressure air supply, and also in the hopper. Since it is necessary to fill a certain amount of the product to be conveyed, equipment for confirming that is required, and it requires a higher energy and a larger space than necessary to convey a small amount of powder or granules. It was not suitable for transporting a small amount of powder that falls. Further, when attempting to carry out low-pressure suction transport of small energy using the transport device having the above-mentioned structure as it is, it becomes a method of sucking air from the entire cutout surface of the transport pipe, so the flow velocity of the air is slow and the powder near the upstream end There is a problem that the granules are difficult to be transported and may cause blockage in some cases. The present invention has been made in view of the above problems, and an object of the present invention is to provide a powder collecting / conveying device capable of collecting a small amount of powder particles falling over a wide range and conveying them at a low pressure. .

能となっている。Embodiments of the present invention will now be described in detail with reference to the drawings. In FIGS. 1 and 2, the upper half of the cylindrical body having the upstream end closed and the downstream end communicated with one end of the suction pipe 2 under the shunt 1 serving as a powder and granular material collection container is located from the upstream end to the downstream side. A transport pipe 3 cut out by a predetermined length is fixedly attached to the shoe 1, and the transport pipe 3 and the shoe 1 are connected to each other at a lower end position in a longitudinal direction in the shoe 1. A guide support 4 having an A-shaped cross section is attached so as to extend in parallel with. The guide support 4 has both lower ends thereof and the shoe.
The granular material passage gap 5 is defined by the inner wall surface of the belt 1, and the lower chamber 6 having a cross section perpendicular to the transport direction and the cross sectional space of the transport pipe 2 have substantially the same size. ing. Further, the guide support 4 has an air inlet 7 communicating with the inside and outside thereof on both lower side surfaces of the upstream end thereof, and the total area of the air inlet 7 and the granular material passage gap 5 is the above-mentioned. The cross-sectional area of the suction tube 2 perpendicular to the transport direction is made approximately equal,
Moreover, the opening area ratio of the air inlet 7 is made as large as possible. Furthermore, the cross section of the guide support 4 is hermetically sealed so that air cannot enter and leave the upper part partitioned by a partition 8 having an A-shape. Further, a low-pressure suction blower is connected to the far downstream side of the suction pipe 2 so that the powder and granules can be collected and conveyed.

することになり、滞りなく輸送が可能となる。In order to actually collect and convey the powdery particles by this apparatus, first, the main body is placed below the adhering sand-discharging portion of the foundry sand conveyor belt conveyor so that the longitudinal direction is orthogonal to the traveling direction of the belt conveyor. Located in. Next, after activating the belt conveyor, a low pressure suction blower (not shown) is activated to generate an air flow from the upstream side to the downstream side in the transport pipe 2, so that the powder blown off from the belt conveyor is discharged. The granules are collected by falling into the shunt 1, pass through the granule passage gap 5 through the transport pipe 3 toward the downstream direction, and pass through the suction pipe 2 to form a low pressure blower. It is carried into a connected dust collecting container (not shown). At that time, if the air flow in the transportation pipe 2 is temporarily stopped due to an external factor and the accumulation 9 of the granular material occurs in the transportation pipe 2, it becomes difficult for the air flow to pass through the transportation pipe 2. However, since the air flow can pass through the lower chamber 6, the air flow whose passage cross-sectional area is reduced and the flow velocity is increased by the deposition 9 gradually carries out the deposition 9, and finally the deposition 9 disappears. As a result, transportation will be possible without delay.

It is possible to efficiently carry the sheet without causing blockage or the like.
