Description

Bucket for bucket elevator for preventing attached light

The present invention relates to a bucket for a bucket elevator for preventing adhesion light, and more particularly, by preventing adhesion light from being generated on the inside of the bucket during unloading of mineral raw materials such as iron ore or coal loaded on a ship using the bucket elevator. It relates to a bucket that can increase the unloading capacity.

In general, iron ore or coal used as a mineral raw material during blast furnace operation in a steel mill is transported by ship, unloaded at the pier, and then transported to the yard of the plant through transport facilities such as a belt conveyor.

Mineral raw materials such as coal or iron ore loaded on the ship are transported to the outside of the ship using a bucket elevator 1 called a continuous unloader shown in FIG. 1 . In the bucket elevator 1, a boom is installed above the traveling unit 5 moving along the pier, and a plurality of buckets 7 rotate along the elevator post 3 connected to one side of the boom while forming an endless track.

After the bucket elevator (1) enters the ship's storage, mineral raw materials such as iron ore or coal are excavated into a bucket on the lower part of the elevator and discharged to the upper part. It is put in and transported to the yard through several belt conveyors.

When the mineral raw material is unloaded using a bucket elevator, iron ore or coal is attached to the inner surface of the bucket due to moisture, and an attached ore is formed. When the attachment light is formed in this way, the storage capacity of the bucket is reduced and it is impossible to accurately contain the specified amount, so the unloading amount is reduced, and the weight of the entire bucket is increased, causing many problems such as premature wear of the conveyor chain and chain sprocket.

Accordingly, in order to solve the problem of the attachment light generated in the bucket, Korean Patent Laid-Open No. 10-2013-0134378 discloses an attachment light removal device for a bucket, and Korean Patent Laid-Open No. 10-2003-0021478 discloses an automatic attachment removal type bucket. An elevator is disclosed.

The above techniques are a method of removing the attachment light by hitting the bucket from the outside to give a strong impact to the bucket. These conventional techniques have a problem in that a separate driving device for giving an impact to the bucket must be installed on the outside of the bucket. In addition, since the conventional techniques are techniques for removing the attachment light after the attachment light is generated, there is a problem in that the generation of the attachment light itself cannot be prevented.

The present invention was created to improve the above problems, and it is an object of the present invention to provide a bucket for a bucket elevator that can effectively prevent the attachment light from being generated from the inside of the bucket only with a simple configuration that does not use power.

The bucket for a bucket elevator for preventing adhesion light of the present invention for achieving the above object is a bucket that is mounted in a bucket elevator for unloading mineral raw materials including iron ore or coal and rotates along a caterpillar, the bucket of a plurality of guide ribs spaced apart from each other and arranged side by side; and hairy means installed between the guide ribs and spaced apart from the bottom of the bucket to shake the mineral raw material downward when the bucket is turned over and the mineral raw material is discharged to the outside of the bucket.

The hair means includes a chain formed by successively forming a plurality of weight members so that the shape can be deformed, a first fixing member installed on the inner surface of the bucket to which one end of the chain is coupled, and installed on the inner surface of the bucket and a second fixing member to which the other end of the chain is coupled.

The chain is formed to be longer than the distance between the first fixing member and the second fixing member so that the chain can be sagged by its own weight.

The weight member has a ring shape.

The bottom of the bucket is open, the guide ribs are disposed across the bottom of the bucket, and the fur means is installed to cover the bottom of the bucket.

As described above, in the present invention, by installing a hairy means made of a chain at the bottom of the bucket, when the bucket is turned over and the mineral material is discharged, the chain shakes off the mineral material, so it is possible to prevent the attachment light from occurring on the inside of the bucket. have.

Accordingly, the present invention can prevent a decrease in the unloading capacity of the bucket due to the generation of the attachment light.

In addition, the present invention can effectively prevent the attachment light from being generated inside the bucket only by a simple configuration of a chain sagging by its own weight without using power.

Hereinafter, a bucket for a bucket elevator for preventing adhesion light according to a preferred embodiment of the present invention will be described in detail.

2 to 6, the bucket 10 according to an embodiment of the present invention is installed in the bucket elevator. Bucket elevators are used for unloading mineral raw materials including iron ore or coal. A chain 9 that rotates while forming an endless track is installed in the bucket elevator, and buckets 10 are mounted on the chain 9 at regular intervals.

The bucket 10 has a barrel structure with an open top. The bucket 10 excavates the mineral raw material from the lower side of the elevator and rises in a state in which a certain amount of the mineral raw material is filled therein. And as the direction is changed on the upper side of the elevator, the bucket 10 is turned over, and at this time, the mineral raw material is discharged to the outside. The bucket 10 is turned over and descends in an empty state.

As long as the bucket 10 has a structure that can contain a mineral raw material therein unlike shown, its shape and size may be variously changed.

The bucket 10 of the present invention is provided with a guide rib 20 and a hairy means on the inside.

A plurality of guide ribs 20 are provided. The guide ribs 20 may be arranged side by side at regular intervals. In the illustrated example, the guide rib 20 is installed on the inclined floor inside the bucket 10 . The guide rib 20 is formed to protrude from the inner bottom of the bucket 10 . Both ends of the guide rib 20 may be formed to extend to a predetermined height on the side wall of the bucket 10 .

The guide rib 20 is preferably formed of a metal material having excellent strength and durability. For example, high manganese steel may be used as a material of the guide rib 20 .

Hair means is installed on the inside of the bucket (10) to cover the bottom of the bucket (10). Therefore, when the mineral raw material is put in the bucket 10, the contact of the mineral raw material with the bottom of the bucket 10 is blocked by the hairy means. And when the bucket 10 is turned over and the mineral raw material is discharged to the outside of the bucket 10, the hairy means sags by its own weight and is spaced apart from the bottom of the bucket 10 to shake off the mineral raw material downward.

The illustrated hair means is, for example, a chain 30 in which a plurality of weight members 31 are successively formed so as to be deformable in shape, and is installed on the inner surface of the bucket 10 so that one end of the chain 30 is coupled. A first fixing member 35 and a second fixing member 37 installed on the inner surface of the bucket 10 to which the other end of the chain 30 is coupled is provided.

The chain 30 forms a plurality of weight members 31 in succession.

The weight member 31 is preferably formed of a material having a large specific gravity. For example, the weight member 31 may use a metal material. As the metal material 31, a metal having excellent strength and durability is used.

The weight member 31 may have a ring shape. Such a ring may be made of a circle, an oval, a square, or the like. In the illustrated example, the weight member 31 has an elliptical ring shape. A plurality of ring-shaped weight members 31 are coupled to each other to form a chain 30 of a certain length. Since the weight member 31 can move freely at the connection portion between the weight members 31, the chain 30 is easily deformed in shape, such as bent or unfolded.

The chain 30 is arranged in two rows between the two guide members 20 . Unlike this, of course, the chain 30 may be arranged in one line or three lines or more. The chain 30 may be arranged neatly by the guide member 20 when moving up and down. The guide member 20 prevents the chains 30 from being entangled or disturbed with each other.

The first and second fixing members 35 and 37 are installed on the inner surface of the bucket 10 .

The first fixing member 35 is coupled to one end of the chain 30 and serves to fix one side of the chain 30 to the bucket 10 . The first fixing member 35 may be formed on the bottom of the bucket 10 or the side wall of the bucket 10 . The first fixing member 35 may be formed in the form of a U-shaped ring on which the weight member 31 of the chain 30 can be hung.

The second fixing member 37 is coupled to the other end of the chain 30 and serves to fix the other side of the chain 30 to the bucket 10 . The second fixing member 37 may be formed on the bottom of the bucket 10 or on the sidewall of the bucket 10 . In the illustrated example, the second fixing member 37 may be formed in the form of a U-shaped ring on which the weight member 31 of the chain 30 can be hung.

The distance between the first fixing member 35 and the second fixing member 37 is shorter than the length of the chain 30 . That is, the length of the chain 30 is longer than the distance between the first fixing member 35 and the second fixing member 37 . Accordingly, the chain 30 made by successively connecting the plurality of weight members 31 is easily sagged downward by its heavy weight.

When the bucket 10 is in the elevated position of FIG. 2 , the chain 30 is drooping by its own weight, and as shown in FIG. 4 , the chain 30 is seated on the bottom of the bucket 10 . And when the bucket 10 is turned over and in the descending position of FIG. 2 , the chain 30 is drooping downward by its own weight while the chain 30 is spaced apart from the bottom of the bucket 10 . When the bucket 10 is turned over, the chain 30 is drooping by its own weight and separated from the bottom of the bucket 10 in an arch form as shown in FIGS. 7 and 8 . When the bucket 10 is turned upside down, the chain forms an arc and droops downwardly, and serves to shake off the mineral raw material at the bottom of the bucket 10. Accordingly, it is possible to effectively prevent the attachment light from occurring on the inside of the bucket 10 .

On the other hand, although the above-described embodiment has been described as an example of a structure in which the bottom of the bucket is blocked, unlike this, the bottom of the bucket may not be blocked.

9 to 11, the bottom of the bucket 10 is not blocked and is open. A part expressed in color in FIG. 11 means an open part (A) of the floor.

The guide ribs 20 installed inside the bucket 10 are arranged to cross the open bottom of the bucket 10 . Both ends of each of the guide ribs 20 are coupled to the inside of the side wall of the bucket 10 .

The first and second fixing members 35 and 37 of the hairy means are installed inside the side wall of the bucket 10 . And both ends of the chain 30 are connected to the first and second fixing members 35 and 37 . Therefore, since the chain 30 is installed to cover the open bottom of the bucket 10, mineral raw materials can be put into the bucket 10 even if the bottom of the bucket 10 is not blocked.

If the mineral raw material is a fine powder, the mineral raw material cannot be filled in the bucket with a hole in the bottom, but since most mineral raw materials are in the form of small lumps, the inside of the bucket of the present invention where the hair means covers the bottom can be filled by putting the mineral raw material .

When the bucket 10 is turned over, the chain 30 droops downward by its own weight and shakes the mineral raw material in the bucket 10 downward.

As mentioned above, although the present invention has been described with reference to one embodiment shown in the drawings, this is merely an example, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. will be. Accordingly, the true technical protection scope of the present invention should be defined by the technical spirit of the appended claims.
