Description

[Detailed description of the invention] This invention relates to an improvement of a rough stone dewatering device used in combination with a dry sand machine.

The dehydration device previously proposed by the applicant (Japanese Patent Publication No. 55-240
2ff Publication), when moisture and sludge adhere to the rough stone, the moisture and sludge are separated from the rough stone by the wind blown by a blower (not shown), as shown in Figures 1 and 2. The separated raw stones, moisture, and sludge are discharged from the opening 2b of the dehydration cylinder 2 and collide with the conical portion 6' of the rotating body 6, which is rotated by any means.

At this time, the moisture and hetOc remaining on the surface of the rough stone
It is completely separated and removed from the raw stone.

The raw stone from which moisture and sludge have been removed collides with the conical portion 6' of the rotating body 6, bounces into the casing 1, and enters the raw stone chute 10.

In addition, the moisture and sludge separated from the raw stone and the moisture and sludge discharged from the dehydration cylinder 2 are blown away from the surface of the conical part 6' of the rotating body 6 to the surroundings by the wind blowing from the dehydration cylinder 2. , adheres to the partition plate 5.

This partition plate 5 is formed of a wire mesh having a truncated conical shape,
A hole 5a is provided in the center of the partition plate 5, which is large enough for the conical portion 6' of the rotating body 6 located at the rear of the partition plate 5 to protrude, but the partition plate 5 is stationary and does not vibrate. Since it is a so-called stationary object that is not given anything, a diary gradually forms, and the moisture and sludge adhering to the rough stone chute 10 side of the partition plate 5 no longer flows into the second liquid chute 11 on the back side of the partition plate 5.

The present invention has been devised to eliminate the above-mentioned drawbacks, and the present invention will be explained below with reference to FIGS. 3 to 6.

Here, the present invention having the same reference numerals as those in FIGS.
The same parts as those in the figure are shown.

Reference numeral 1 denotes a casing, and 2 a dehydration tube inserted horizontally into the casing 1 from the side of the casing 1. One end 2a of the dehydration tube 2 is connected to a blower (not shown).

In addition, notches 3 are provided at several locations on the lower edge of this dewatering cylinder 2.

Reference numeral 4 denotes a hopper for charging raw stones into the dewatering cylinder 2, and is installed outside the casing 1.

Reference numeral 13 denotes a flat partition plate attached to the inner surface of the casing 1 at right angles to the casing 1, and a hole 13a with a diameter slightly smaller than the diameter of the rotating body 14 is provided in the center of the partition plate 13 at a position facing the dehydration cylinder 2. is the provision.

In short, the inside of the casing 1 is divided into two parts by the partition plate 13.
It is divided into rooms.

Reference numeral 14 denotes a rotating body positioned in the other chamber of the casing 1 at a position facing the dehydration cylinder 2.

This rotating body 14 includes a disk holding flange 14a and a disk 14b provided on the side of the dewatering cylinder 2 of the disk holding flanch 14a.
and a basket 14c made of wire mesh, which has a truncated conical shape that widens toward the dehydration cylinder 2 welded to the outer periphery of the disk 14b, and has a collar plate that extends in the vertical direction on the tip edge; Consisting of a collision plate 14d provided on the side of the dewatering cylinder 2 of the plate 14b, the waist disk holding flange 14a and the disk 14b are fully in contact with each other and fixed with screws. The collision plates 14d of the disks are made into one piece by screwing them in full contact with each other so that they can be removed, and by screwing the disk holding flange 14a to the rotating shaft 7, they can be removed and removed from the rotating shaft 7. installed.

8 is a pulley attached to the rotating shaft 7, 9 is a first liquid chute connected to the lower part of the dewatering cylinder 2, 10 is an ore chute installed to surround the first liquid chute, and 11 is a rotating body 1
a second liquid chute installed at the bottom of the compartment containing 4;
Reference numeral 12 denotes a leg section attached to the periphery of the casing 1.

In the above configuration, air is sent to the dehydration cylinder 2 from a blower (not shown), and the rotating shaft 7 is rotated by an arbitrary means to rotate the rotating body 14.

When raw stones are put into the hopper 4 in this state, the raw stones pass through the hopper 4 and move into the dewatering cylinder 2.

Then, this rough stone is blown toward the opening 2b of the dehydration tube 2 by the wind sent from the blower connected to one end 2a of the dehydration tube 2.

At this time, the water and sludge adhering to the surface of the raw stone are separated from the raw stone, and a part of it is discharged from the lower part of the first liquid chute 9 to the outside through the notch 3 provided at the lower part of the deicing cylinder 2.

Then, the remaining moisture and sludge and the separated raw stones are released from the opening 2b of the dehydration cylinder 2, and the collision plate 14d of the rotating body
collide with

At this time, the moisture and sludge remaining on the surface of the rough stone are
Because it collides head-on with the impact plate, it is completely separated from the rough stone and removed.

Here, the rough stone from which water and sludge have been completely removed collides with the collision plate 14d of the rotating body, bounces into the casing 1, enters the rough stone chute 10, and is discharged from the lower part of the rough stone chute 10 to the outside.

In addition, moisture and sludge separated from the rough stone, moisture and sludge discharged from the dehydration cylinder, and the wind blowing from the dehydration cylinder 2 adhere to the surface of the collision plate 14d, and centrifugal force causes the outer periphery of the disc 14b. It is thrown off from the surface to the basket 14c section.

The basket 14C has a truncated conical shape that widens in the direction of the dewatering cylinder 2, that is, it is inclined in the opposite direction to the direction of the wind, so that the centrifugal force due to the rotation of the rotating body is applied in the same direction as the wind direction. It will affect.

When this component force is added to the force of the wind, moisture and sludge more easily pass through the wire mesh basket 14c and flow into the second liquid chute 11 on the back surface of the basket 14c.

Moreover, even if some of the water and sludge is removed from the basket 14c,
Even if it is shaken off by centrifugal force from the tip of the basket 14c, the tip of the basket 14c is provided with a flange plate in the vertical direction, and the flange plate of the tip of the basket 14C is placed on the chamber side of the second liquid chute 11. Furthermore, since a gap is formed between the collar plate and the periphery of the hole 13a of the partition plate 13, moisture and water are reliably discharged from the gap into the chamber on the second liquid chute side. Moisture and sludge will not fall into the room on the rough stone chute 10 side.

As explained above, the present invention includes a casing 1 whose interior is divided into two chambers by a vertical partition plate 13 having a hole 13a in the center, and a casing 1 which is inserted horizontally into one chamber and has a tip opening 2b. A pressure-feeding cylinder 2 located near the hole 13a of the partition plate 13, the other end 2a outside the casing 1 connected to a blower, and a hopper 4 provided in a part outside the casing 1.
In the other chamber, there is a collision plate 14d in the center, which is disposed opposite to the tip opening 2b of the pressure-feeding cylinder 2 and the hole 13a of the partition plate 13, and on the outer periphery of the collision plate 14d, A rotating body 14 configured by fixing a basket 14c having a flange plate on the edge of the opening at the tip formed of a truncated cone-shaped wire mesh or the like;
It consists of an ore chute 10 provided in the lower part of one chamber and a second liquid chute 11 provided in the lower part of the other chamber. The hole 13a of the plate and the partition plate 13
This is a dewatering device for rough stones in a dry sand making machine that has a slight gap between the periphery of the stone and the periphery of the stone. Even if the basket becomes clogged, the clogging can be resolved by removing the entire disc and cleaning it, or in the worst case by replacing it.

In the present invention, a flange plate is provided at the opening edge of the basket that constitutes the rotating body, and a gap is formed between this flange plate and the periphery of the hole in the partition plate, so that water that has not passed through the mesh of the basket can be removed. The sludge eventually reaches the chamber on the second liquid chute side from the opening edge of the basket, passes through the gap, and does not enter the chamber on the raw stone chute side.

Here, in this embodiment, a basket made of wire mesh is welded to the disc, but the present invention is not limited to this, and it goes without saying that the basket may be removable like the collision plate.
