Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a turntable device for a large storage tank such as a silo.

[Conventional technology and problems]

In general, a turntable that receives powder and granular material discharged from a discharge port formed in a storage tank and supplies the powder onto a discharge conveyor using a discharge device such as a plow provided at a predetermined location is shown in Fig. 4. As shown in FIG. 2, since the powder is in the form of a simple flat ring, the bulk of the powder and granules is low, and therefore the dispensing capacity is restricted and the conveying capacity is low.

[Means for solving problems]

The present invention was developed in view of the above-mentioned circumstances.The structure of the present invention, which solves the problems of the prior art, is that the powder and granules discharged by a dispensing device such as a plow from a dispensing port formed in a storage tank are In a ring-shaped turntable, the powder and granular material is discharged and supplied onto a conveyor at a predetermined location, and the hem end is in contact with the turntable surface on the entire outer edge of the turntable. ,or,
Annular skirt members made of flexible material are provided adjacent to each other and rotate at the same speed as the turntable, and a portion of both the inner and outer skirt members are connected to the turntable by a guide member. The present invention is characterized in that an external part for supplying falling powder and granular material is formed by separating from the inner edge of the container, and the above-mentioned delivery conveyor is made to face below this external part.

〔Example〕

To explain the details of the embodiment with reference to the drawings, 1 is a silo body, 2 is a cone, 3 is a powder discharge port formed in the circumferential direction of the silo body 1, 4 is a discharge device such as a plow, and 5 is a ring-shaped It is a turntable.

In such a device, the present invention has a base end that contacts or approaches the turntable surface on the entire outer edge of the turntable 5, and rotates at the same speed as the turntable 5. Inner and outer ring-shaped skirt members 6 and 7 made of flexible material are provided. The upper edges of both skirt members 6, 7 are suspended from two parallel rails 8, 9, which are ring-shaped and arranged above the turntable 5, and are driven by a drive device (not shown). It is rotated at the same speed as the above turntable.

As shown in FIG. 3, parts of the skirt members 6 and 7 are guided and outwardly guided laterally from the inner edge of the turntable 5 while being held between multiple sets of two guide rolls 10. A dispensing conveyor 12 faces below this dispensing part 11, and the powder on the turntable 5 is discharged from the dispensing part 11 and delivered onto the dispensing conveyor 12.

[Effect of idea]

As described above, according to the present invention, compared to the conventional technology,
Practical effects include the ability to greatly increase the storage capacity of powder and granular material on the turntable, the ability to transport and supply it to the delivery conveyor, and the need for a delivery device such as a plow or a scraper on the turntable to be omitted. is big.

Claims (1)

[Scope of Claim for Utility Model Registration] Powder and granules are received from a dispensing port formed in a storage tank by a dispensing device such as a plow, and the powder and granules are discharged and supplied onto a dispensing conveyor at a predetermined location. In a turntable device for a large storage tank, on the entire outer edge of the turntable,
An annular skirt member made of a flexible material whose hem end touches or is close to the turntable surface and rotates at the same speed as the turntable is provided, and both the inner and outer skirt members are A part of the turntable is detached from the inner edge of the turntable by a guide member to form an external part for supplying falling powder and granules, and the above-mentioned delivery conveyor is made to face below this external part. A turntable device in a large storage tank.
