Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box-shaped chute device in which an upper portion of one side communicates with a powder outlet of a bucket conveyor and a lower end communicates with a powder inlet of a storage hopper.

[0002]

2. Description of the Related Art Conventionally, as described above, a box-shaped chute device for communicating a powder material outlet of a bucket conveyor with a powder material inlet of a storage hopper is disclosed in Japanese Utility Model Application Laid-Open No. 62-15781.
As shown in Japanese Patent Application Publication No. 8 (1996) -1994, a bucket conveyor is generally formed in a tapered shape in which a side surface located at a lower portion of a granular material discharge port is formed as an inclined plate. This inclined plate is a distance from the powder discharge port of the bucket conveyor to the powder receiving port of the storage hopper (the powder receiving port is provided at the center of the upper end of the storage hopper in order to prevent bias of the powder input. In general, the larger the storage hopper, the longer the distance between them becomes.).

[0003]

As described above, in the box-shaped chute having a long inclined plate, the powdery material discharged from the bucket conveyor is thrown into the inclined plate at a high speed and is charged. In the case of treating a granular material having a property, there is a problem that the granular material adheres to the inclined plate, which grows and closes the box-shaped chute device or falls as a large lump. The present invention has been made in view of the above-described problem, and in a box-shaped chute device that connects a bucket conveyor and a storage hopper, the device may be blocked due to the adhesion of the granular material to be transferred, or the granular material may have a large lump. It is an object of the present invention to provide a box-shaped chute device capable of preventing the falling of the box-shaped chute.

[0004]

In order to achieve the above-mentioned object, a box-shaped chute apparatus according to the present invention has an upper portion on one side communicating with a powder material outlet of a bucket conveyor, and a lower portion connected to a powder material of a storage hopper. A bottom-thin box-shaped chute device which is communicated with a body receiving port and has a side surface located at a lower portion of the powder material discharge port formed by an inclined plate, wherein a plurality of thin plate members are provided above the inclined plate. An inclined slit body, which is arranged in an armor plate shape as a whole by providing a small gap at the upper and lower ends and arranged in an overlapped manner, is arranged parallel to the inclined plate at an interval with respect to the inclined plate, the upper end thereof is closed, and the lower end is powdered. An air chamber provided with a body opening is defined, and an air introduction pipe communicating with a blower or a hot air blower is communicated with an upper end portion in the air chamber.

[0005]

Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, a powder outlet 2 is provided at an upper portion of a bucket conveyor 1, and a storage hopper 3 is disposed below the powder outlet 2 of the bucket conveyor 1, and a storage hopper 3 is provided at the upper center thereof. The part is provided with a granular material receiving port 4. Further, a box-shaped chute W is connected between the granular material discharge port 2 and the granular material receiving port 4.

[0006] The box-shaped chute W is constructed as follows. A lower tapered shape in which one upper portion is communicated with the powder / particle discharge port 2, and a lower end portion is communicated with the powder / particle receiving port 4, and a side surface located at a lower portion of the powder / particle discharge port 2 is an inclined plate 5. Is formed. Above the inclined plate 5, a plurality of thin plate members 6, 6 are provided with a slight gap at the upper and lower ends, respectively, and are superposed and arranged. They are arranged in parallel at intervals.

The upper end of the inclined slit body 7 has a mounting plate 7A.
, Forming a powder discharge opening 8 at the lower end,
Air chamber 9 between inclined plate 5 and inclined slit body 7
Is defined. An air introduction pipe 10 communicating with a blower (not shown) or a hot air blower is connected to the upper end of the air chamber 9. (See FIG. 2) Further, a vibration motor 11 for generating vibration is mounted on the side surface of the main body of the box-shaped chute device W. Reference numeral 12 in the figure
Denotes a suction duct communicating with a dust collector (not shown);
Is an inspection window used for replacing the inclined slit body 7.

[0008] The suction duct 1 constructed as described above is used.
2 is connected to a dust collector (not shown) and the air introduction pipe 10 is connected to a blower or a hot air blower (not shown) to supply cool air or hot air into the air chamber 9, and the air flows through the gap of the inclined slit body 7 as shown by arrow B in FIG. As shown in FIG. 1, the granular materials are introduced from the bucket conveyor 1 through the granular material discharge port 2 while flowing along the inclination of the thin plate materials 6, 6. , And slides down the inclined portion, and is accumulated in the storage hopper 3 from the powder-particle receiving port 4.

During this time, the powder particles falling on the inclined slit body 7 are forcibly blown away by air flowing out from the gaps of the inclined slit body 7 and hardly adhere to the surfaces of the thin plate members 6, 6. If the vibration motor 11 is operated, the effect of preventing adhesion can be further enhanced.
Further, a part of the granular material that has entered the air chamber 9 from the gap of the inclined slit body 7 as shown by the arrow C is dropped into the granular material receiving port 4 from the powder discharging opening 8 at the lower end. Further, a part of the light granular material that flew off the arrow S and was raised by the arrow T
And is settled or sucked into the suction duct 12 as shown by the arrow U.

[0010]

As is apparent from the above description, the present invention has a structure in which a plurality of thin plate members are superposed and arranged with a slight gap at each of the upper and lower ends above the inclined plate to form an armor plate as a whole. The inclined slit body is disposed in parallel with the inclined plate at an interval, and the upper end is closed and an air chamber provided with a powder discharge opening at the lower end is defined, and at the upper end in the air chamber. Since the air introduction pipe communicating with the blower or the hot air blower is connected, the powder and granules fed from the bucket conveyor are adhered to the inside of the device and blocked, or the lump of the powder and granules is formed and dropped. Inconvenience can be prevented, and the effect is remarkable.
