Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is aimed at reducing the amount of emissions in rotary silo discharging equipment for storing so-called bulk materials (hereinafter referred to as stored materials) such as powder, granules, or lumps. relating to an adjustment device.

[Prior Art] In order to store stored materials such as coal, lime, fertilizer, and wood chips in a container and discharge them as necessary, the container has a discharge port 3 at the bottom as shown in FIG.
A silo 1 provided with a cone 5 covering its discharge port 3 is used. Note that 4 is a support beam that supports the cone 5 on the silo 1. Stored items are at the bottom outlet 3
Therefore, since the stored material is located below the cone 5 at a predetermined angle of repose up to the outlet, the bottom covered by the cone 5 If a rotary scraper 9 is provided at the discharge port 3 of the rotary scraper 9, when it is operated, the angle of repose collapses and the stored material starts to be discharged automatically. After a predetermined amount has been discharged, the stored material regains its angle of repose and stops discharging. By repeating this operation, the required amount of stored material is discharged,
It can be transported to a desired location by means of transportation such as freight cars, automobiles, or conveyor belts.

In such a silo, in order to accommodate changes in the angle of repose due to changes in the type of stored material and to enable adjustment of the discharge amount, a gap between the lower end of the cone 5 and the bottom plate 2 forming the discharge port 3 is provided. A sleeve 6 is usually provided for adjusting the .

However, as shown in FIG.
is supported by a plurality of bolts 7 from the cone 5, so in order to change the position of the sleeve 6, a person needs to enter the cone 5 and operate the bolts 7.

By the way, when the scraper 9 rotates, the sleeve 6 moves up and down due to stored material that enters the gap between the lower end of the cone 5 and the bottom plate 2, so lock nuts 8, 8 are always required to secure the sleeve 6 to the bolt 7. It is. Therefore, when adjusting the position of the sleeve 6, it takes about one hour to loosen the lock nuts 8, 8, adjust the sleeve with the nut 8a, and tighten the lock nuts 8, 8. Therefore, the workability was poor.

[Object of the Invention] Accordingly, an object of the present invention is to provide a discharge amount adjusting device for a rotary silo discharging facility that improves the workability of adjusting the discharge amount.

[Structure of the Invention] According to the present invention, the bottom plate has a discharge port, a cone supported by a support beam is provided above the discharge port, and the gap between the cone and the discharge port is closed by a sleeve. In a discharge regulating device for a rotary silo discharging facility, which regulates and discharges stored material by a rotary scraper rotating through the gap,
a handle for threading onto a downwardly extending bolt supported by a support beam, the sleeve being guided to a guide rod through a plurality of through holes formed in the top surface of the sleeve; supported above.

[Operations and Effects of the Invention] Therefore, the discharge amount can be adjusted by operating the handle from the discharge port without entering the inside of the cone, and as a result, workability can be greatly improved.

Also, since the sleeve is guided by the guide rod,
It is possible to prevent the center of the sleeve from swinging out, and to easily assemble and disassemble the sleeve.

[Preferred Embodiment] When carrying out the present invention, it is preferable that the circumferential surface of the sleeve is formed into a conical surface comparable to that of a cone. In this way, the vertical movement of the sleeve during discharge is suppressed by the pressure of the stored material applied to the conical surface, making it possible to eliminate the need for a lock nut and further improve workability.

[Examples] Examples of the present invention will be described below with reference to the drawings.

Portions in FIG. 1 that correspond to those in FIG. 3 are given the same reference numerals and redundant explanation will be omitted.

In FIGS. 1 and 2, the sleeve 6a is a cup-shaped member that opens downward, and its peripheral surface is formed into a conical surface of the same extent as the cone 5, and its opening is in contact with the bottom of the cone 5. They are formed to have approximately the same diameter. A plurality of (three in the illustrated example) through-holes 10 formed on the top surface are engaged with three guide rods 11 that are concentrically vertically disposed below the cone 5. Note that 12 is a rib reinforcing the vicinity of the through hole 10 on the top surface of the sleeve 6a, and 14 is a boss at the center of the sleeve supported by three ribs 13 from the top surface.

On the other hand, a bolt 15 extending downward from the center of the cone 5 is suspended from the support beam 4, and a handle 16 screwed onto the bolt 15 is provided at the lower end of the bolt 15. Then, a boss 14 is placed on this handle 16.
The sleeve 6a is supported through the handle 16, and when the handle 16 is turned and screwed in, the sleeve 6a is moved upward by the handle 16 from the position indicated by the solid line to the position indicated by the two-dot chain line, and when the handle 16 is loosened,
It is adapted to be moved downward by the weight of the sleeve 6a.

When coal, lime, fertilizer, wood chips, etc. are put into the silo 1, these stored materials flow out from the gap between the lower end of the sleeve 6a and the bottom plate 2 toward the outlet 3, and come to rest at an angle of repose specific to the material. do. When the scraper 9 is rotated to discharge the stored material, the scraper 9 discharges the stored material that is stabilized around the outlet 3 of the bottom plate 2 into the outlet 3 at an angle of repose. Then, the stored material in the hopper automatically flows down and is discharged, and after a certain amount is discharged from the discharge port 3, it becomes stable again at an angle of repose peculiar to the material. As long as the scraper 9 continues to rotate, the stored material will continue to be discharged.

If it becomes necessary to change the discharge amount, that is, the discharge speed of the stored material, or if the angle of repose changes due to a change in the stored material, it becomes necessary to adjust the position of the sleeve 6a up or down to accommodate this change.

At this time, by rotating the handle 16 from the discharge port 3, the sleeve 6a can be moved up and down as described above to easily change its position.

In addition, a downward force is applied to the sleeve 6a due to the pressure of the stored material applied to the conical circumferential surface of the sleeve 6a, so that the vertical movement of the sleeve 6a during discharge is suppressed. work efficiency is improved accordingly.

Further, since the sleeve 6a is guided by the guide round rod 11 through the through hole 10, center runout is prevented, and workability in assembling and disassembling the sleeve 6a is improved.

[Summary] As explained above, according to the present invention, it is possible to easily adjust the discharge amount by operating the handle from the discharge port without entering the inside of the cone, and as a result, the silo The utility value increases significantly.
