Description

Top covering device of blending bean {DEVICE FOR COVERING BLENDING BIN}

The present invention relates to a blending bin into which the raw coal is charged in the coal lathe. More specifically, the present invention relates to an upper covering device of a blending bin, which is installed on the blending bin to prevent dust from scattering and to handle falling lights.

Generally, various ores from different origins are deposited in yards by type of coal by raw material processing facilities. Each raw coal is discharged to the recramer according to the mixing plan and then crushed by coal type in the crusher. The crushed raw coal is stored for each type in the blending bin. The blended bin stored raw coal is disbursed and blended by the blending ratio for each type of coal, dried through a coal dryer, and then transported to colvin.

Raw coal for each coal type is transferred to a tripper car installed at the top of the blending bin using a belt conveyor. The raw material transferred to the tripper car is dropped into the blending bin through the chute and stored. The tripper car moves along the running rail installed on the blending bin and drops raw coal by type of coal to the top of the blending bin opened through the chute.

This causes the raw material to scatter in the form of dust. In addition, a severe air vortex phenomenon occurs in the closed space of the blending bin and the internal volume increases, and a strong scattering force is generated at the top of the blending bin. As a result, a large amount of dust is scattered to the outside of the blending bin.

Therefore, in the related art, the upper part of the blending bin is covered with an iron plate to block dust from scattering to the outside. However, the above-described conventional structure is a structure in which only the entire upper portion of the blending bin is covered with an iron plate, which causes difficulties in processing falling rocks during raw material granulation.

In other words, raw materials or dust falling from the belt conveyor during the granulation process are accumulated on the iron plate covering the upper part of the blending bin. However, in the related art, since the structure of the blending bin is simply closed with an iron plate, there are many difficulties in processing of falling rocks or dust accumulated on the iron plate. In addition, it takes a lot of manpower and effort to handle falling or dust, and in severe cases, the vicious cycle of removing and reinstalling the installed iron plate is repeated.

The present invention provides an upper covering device of the blending bin, which minimizes the generation of scattering dust in the process of charging the coal briquettes and facilitates the treatment of falls.

To this end, the apparatus comprises a plurality of covers which are continuously arranged under the belt conveyor at the top of the blending bin and selectively shield the top of the blending bin, the covers being placed on the installation so that the material settled on the top can be dropped down. It is rotatably installed, and one side of the cover may be provided with a return means for returning the pivoted cover to its original position.

Each cover will block the top of the blending bin. When the fall or dust accumulates on the upper portion of the cover, it is rotated by the weight of the fall or dust, so that the fall or dust can fall down.

The cover may be a structure that is rotatably installed on a rotating shaft which is separated into two and installed on the facility.

The return means may include at least one elastic member elastically installed between the two separated covers.

The cover may be formed in the form of a triangular cross-section in which two members separated about the rotational shaft are inclined downward.

In addition, the cover may be further provided with an auxiliary plate for preventing the occurrence of gap between the cover and the neighboring edge.

As such, the device can block the top of the blending bin to minimize the generation of scattering of the raw coal.

In addition, when falling or dust falling during the raw material granulation process accumulates on the upper cover it is possible to easily handle the fall or dust by rotating the cover mechanically.

This can reduce the time and effort required to handle falls or dust falling to the top of the cover.

Here, the device is installed on the top of the blending bin 100 to which the tripper car 150 is moved. This device is to block the top of the blending bin 100 and to handle falling or dust falling in the process of transporting the raw material to the tripper 150.

To this end, the apparatus includes a plurality of covers 10 which are continuously installed on the top of the blending bin 100 to which the tripper car 150 is moved to block the top of the blending bin 100.

In the present embodiment, each cover 10 is installed in the width direction with respect to the moving direction of the tripper 150 at the top of the blending bin (100). Each cover 10 is formed to extend to a sufficient length to block the top of the blending bin (100). In addition, the covers 10 are continuously disposed along the moving direction of the tripper car 150 to block the entire upper end of the blending bin 100.

In order to install the cover 10, the fixing bar 20 is installed along the moving direction of the tripper car 150 on the facility. The fixed bar 20 is provided with a rotation shaft 30 in the longitudinal direction of the cover at intervals. And each cover is rotatably coupled to each said rotating shaft 30. As shown in FIG.

The cover 10 is cut along the longitudinal direction of the center portion is separated into two members are installed rotatably with each other. For convenience of explanation, the two separated members of the cover 10 will be referred to as the first member 12 and the second member 14.

As shown in FIG. 2, the first and second members 12 and 14 separated into two are provided with fastening hinges 16 and 18 in which the pivot shaft 30 is fitted at the ends. . The fastening hinges 16 and 18 formed on the first member 12 and the second member 14, respectively, are formed at positions shifted from each other so as not to interfere with each other and between the fastening hinges 16 of the first member 12. The fastening hinge 18 of the second member 14 is positioned.

The pivot shaft 30 is installed through the fastening hinge 16 of the first member 12 and the fastening hinge 18 of the second member 14 in order. The first member 12 and the second member 14 are coupled to the rotation shaft 30 by a coupling hinge to form a cover 10. The rotating shaft 30 is fixed to the fixing bar 20. Accordingly, each cover 10 is installed along the fixing bar 20 in a state in which the first member 12 and the second member 14 are rotatable via the rotation shaft 30.

As illustrated in FIG. 3, the cover 10 has a triangular cross-sectional structure in which the first member 12 and the second member 14 are inclined downward with respect to the rotation shaft 30. The angle between the first member 12 and the second member 14 may be variously set in a range in which no gap is generated between the cover and the cover, and is not particularly limited.

In addition, the auxiliary plate 40 extends along the front end of the first member 12 and the second member 14 forming the cover 10. The auxiliary plate 40 overlaps with the auxiliary plate of the neighboring cover to minimize the occurrence of a gap between the cover 10 and the cover 10. The auxiliary plate 40 may be installed only at a neighboring tip between the cover 10 and the cover 10, or may be continuously installed over the entire tip of the cover.

In addition, the device is further provided with a return means for returning to the original state when each member is rotated while maintaining the angle between the first member 12 and the second member 14 of the cover 10 separated into two.

Accordingly, the cover blocks the top of the blending bin by maintaining the triangular shape of the first member 12 and the second member 14. This prevents dust from scattering. When the fall or dust accumulates on the cover 10, each member is rotated by the weight of the fall or dust, so that the fall or dust can fall down. After falling or falling dust, each member returns to its original position by the return means.

The return means includes a leaf spring 50 installed between the inner surface of the first member 12 and the second member 14, as shown in FIG.

In this embodiment, the fixing bracket 52 is installed on the inner surface of the first member 12 and the second member 14 facing each other so that the front end of the leaf spring 50 can be installed.

In addition, the return means is applicable to all of the structural surface that can apply the elastic return force between the first member 12 and the second member 14 in addition to the leaf spring (50).

Hereinafter, the operation of the apparatus will be described with reference to FIG. 4.

The top cover 10 is continuously disposed on the blending bin 100. The cover 10 is in close contact with the tip of the neighboring cover 10 to completely block the top of the blending bin 100 without a gap.

In this state, when the raw material granulation process of the tripper car 150 is performed, the tripper car 150 moves on the blending bin 100 for each type of carbon and proceeds with raw material granulation.

Falling or dust falling from the tripper or belt conveyor during the above operation is accumulated on the cover 10 installed on the top of the blending bin.

When dust or falls are accumulated above a certain weight on the cover 10 as described above, the cover is rotated to drop the falls or dust to the blending bin.

When falling or dust accumulates on the first member 12 or the second member 14 constituting the cover, the first member 12 or the second member 14 is formed around the rotational shaft 30 by the weight of the falling or dust. ) Is rotated.

Therefore, the gap between the cover 10 and the cover 10 is opened and the first member 12 or the second member 14 constituting the cover is further inclined.

Therefore, falling or dust falls along the inclined first member 12 or second member 14 and falls downward through the gap.

In this way, the cover 10 is rotated when necessary while blocking the top of the blending bin, so that dust or falls can be easily handled.

As described above, when the first member 12 or the second member 14 is inclined, the leaf spring 50 installed between the first member 12 and the second member 14 is bent and elastically bent. do.

After falling or dust falls from the cover 10, the first member 12 or the second member 14 rotated by the elastic return force of the leaf spring 50 is returned to its original position.

As the first member 12 or the second member 14 is returned to its original position, the gap between the cover and the cover closes and the gap of the blending bin is blocked by the cover again.
