Description

[0001] Apparatus for manufacturing coal briquette used of dust [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] More particularly, the present invention relates to an apparatus for producing a molded coal, which uses the dust collected in a dust collector to produce a molded coal.

1, a large-capacity suction fan 2 is installed to clean air containing dust and gas generated during the exit work in the blast furnace outlet, and air containing dust is introduced into the suction pipe 15 Lt; / RTI >

In the suction process, primary dust is collected in the pre-dust hoppers 7-1 and 7-2 using a gravity drop method by weight. Thereafter, air containing fine particles is dispersed and sucked into five dust collecting hoppers 20 by a dust collecting method by a bag (not shown) formed in each dust collecting hopper 20.

At this time, the air containing the particulates is attached to the back surface by the bag, and the clean air is sucked through the dust outlet valves 3-1 to 5 and 4-1 to 5 of the hopper The air is dissipated to the stack (chimney) 30 provided at the rear end of the fan 2 at atmospheric air.

The dust attached to the bag also performs pulsing in the order determined for each dust hopper. Here, pulsing refers to closing of the dust collecting outlet valves 3-1 to 5 and 4-1 to 5 of the selected dust collecting hopper 20 to remove dust attached to the bag, (7kg / cm < 2 >) at the center to remove the dust due to the impact thereof.

After pulsing, the dust is dropped and accumulated under the dust hopper 20 and the pre-dust hoppers 7-1 and 7-2. The dust is discharged to the rotary valves 5-1 to 5 and 6-1 ~ 5, 7-3 ~ 4).

The discharged dust is stored in the dust reservoir via the chain conveyor belts 10-1 to 4-. The dust stored in the dust storage joining silo 40 is discharged through the rotary valve 50 which is the discharge valve of the silo 40 and discharged to the dust transfer vehicle 70 via the pug mill device 60. Here, instead of the conveying vehicle 70, a conveyor can be used.

1 and 2, the apparatus for manufacturing molded articles 1 according to an embodiment of the present invention may be installed at a lower portion of the silo 40. [ A conveyor 80 may be disposed below the briquette-forming apparatus. Here, the dust D collected by the dust collector may be stored in the silo 40. [

Accordingly, the apparatus for producing molded articles 1 can produce the molded articles F by using the dust D collected through the dust collector.

Then, the briquettes F produced in the briquetted coal manufacturing apparatus 1 can be conveyed by the conveyor belt 80.

Here, the conveyor 80 may include a pair of conveyor rollers 81, a conveyor belt 82, and a drive motor 83, as shown in Figs. 2 and 3. That is, the drive motor 83 rotates the conveyor roller 81 to convey the molded fuel F that has fallen on the conveyor belt 82.

Accordingly, the briquettes F conveyed by the conveyor 80 can be conveyed to the blast furnace.

2 to 4, the apparatus 1 for manufacturing molded products includes a main body 100, a pair of rollers 200, a driving unit 300 for rotating the rollers 200, A first guide plate 500, a second guide plate 600 and a spray device 700 for spraying oil onto the molded fuel F produced by the roller 200. The circulation device 400 circulates the dust D, And a control unit 800. [0031] Here, the control unit 800 may control the driving unit 300, the circulation unit 400, and the spraying unit 700.

The main body 100 can form the outer shape of the above-described briquette-

The main body 100 may include an inlet 110 formed at an upper portion thereof and an outlet 120 formed at a lower portion thereof.

Accordingly, the dust D is introduced into the main body 100 through the inlet 110. The input port 110 may be formed on the main body 100 such that the dust D can be inserted between the pair of rollers 200. That is, the inlet 110 may be formed to be smaller than the width of the inside of the main body 100, which is disposed at the center of the main body 100 and on which the roller 200 is disposed. Accordingly, the dust D injected through the inlet 110 can be moved to the space between the pair of rollers 200 without leakage.

And, the briquettes F produced by the roller 200 can be discharged to the conveyor 80 through the discharge port 120.

The pair of rollers 200 can be disposed in contact with each other inside the main body 100.

The roller 200 can be rotated by the driving unit 300. Accordingly, the pair of rollers 200 can press the dust D to be conveyed between the pair of rollers 200 to form the molded fuel F.

Here, the roller 200 is arranged on the same horizontal plane as shown in Figs. 3 and 5 (a), but the present invention is not limited to this example, and the roller 200 shown in Fig. 5 (b) It is of course possible to arrange them up and down.

The size of the main body 100 can be reduced compared to a case where a pair of rollers 200 are disposed on the left and right sides.

5, each of the rollers 200 includes a cylindrical roller body 210, a plurality of grooves 220 formed on the outer circumferential surface of the roller body 210, and a plurality of grooves 220 formed on the outer circumferential surface of the roller body 210, 230).

The plurality of grooves 220 may be spaced apart from each other by a predetermined distance d.

Here, the groove 220 may be hemispherical. Accordingly, the molded fuel F can be formed into a spherical shape.

Although the molded fuel F produced by the pair of rollers 200 is formed into a spherical shape by the hemispherical grooves 220, the present invention is not limited thereto. (F) may be formed in various shapes. However, in the case of the molded fuel F formed into the spherical shape F, the feeding is easy and the charging into the blast furnace is easy.

The driving unit 300 may generate a driving force for rotating the roller 200. Here, the driving unit 300 may rotate the rollers 200 individually using a motor or the like. Here, the driving unit 300 may be controlled by the control unit 800.

The driving force for rotating the roller 200 can be transmitted from the conveyor 80 without constituting a separate driving unit 300. That is, as the conveyor roller 81 rotates, the roller 200 can rotate in conjunction. 2, a driving force for rotating the roller 200 using a power transmission device such as a belt 90 may be transmitted from the conveyor roller 81. [

On the other hand, the driving force for rotating the roller 200 may be transmitted from the suction fan 2 of the dust collecting apparatus. Accordingly, the roller 200 can rotate in conjunction with the rotation of the suction fan 2.

Therefore, the rotation of the roller 200 can be interlocked with the rotation of the conveyor roller 81 or the rotation of the suction fan 2, and the rotation of the conveyor roller 81 can be performed by any one of rotation or rotation of the suction fan 2 Even if there is a problem in rotation, the roller 200 can be rotated by receiving the driving force from the other one.

The circulator 400 can circulate the dust D discharged through the pair of rollers 200 to the inlet 110.

5, since the plurality of grooves 220 of the pair of rollers 200 are spaced apart from each other by a predetermined distance d, The dust D may be discharged.

Accordingly, the circulation device 400 can improve the manufacturing efficiency of the molded fuel F by circulating the dust D that is not made of the molded fuel F and re-injecting the dust D into the charging port 110.

The circulation device 400 also prevents the dust D from leaking to the conveyor 80 and prevents the conveyor 80 from being contaminated by the dust D. [

3, the circulation device 400 includes a suction plate 410 having a suction hole 411 formed therein, one side connected to the suction plate 410 and the other side connected to a suction pipe (not shown) 420 and a pump 430 disposed in the suction pipe 420.

As the pump 430 of the circulation unit 400 is driven, the dust D discharged through the pair of rollers 200 can be discharged to the charging port 110.

The suction plate 410 may be disposed inside the main body 100. The suction plate 410 may be inclined downward at a predetermined angle.

As shown in FIG. 6, the suction plate 410 may be formed in a V shape. A plurality of suction holes 411 may be disposed at the center side edge of the suction plate 410. Here, the suction hole 411 may communicate with the suction pipe 420 through a passage (not shown) formed in the suction plate 410.

Therefore, the dust D falling to the suction plate 410 is gathered at the center, and can be sucked through the suction hole 411. [ The dust D may be transferred through the suction pipe 420 and then discharged to the inlet 110.

The first guide plate 500 can guide the dust D and the molded fuel F discharged through the pair of rollers 200 to the suction plate 410.

For example, since the dust D is transferred to the inlet 110 through the suction plate 410 and the molded fuel F is discharged through the outlet 120, Lt; / RTI >

Thus, the first guide plate 500 prevents some of the dust D from being discharged through the discharge port 120.

Here, the first guide plate 500 may be disposed inside the main body 100 and be inclined downward at a predetermined angle.

The second guide plate 600 can guide the briquettes F falling downward through the suction plate 410.

The second guide plate 600 may be disposed on the lower side of the suction plate 410 so as to be inclined downward. A plurality of second guide plates 600 may be disposed so as to be spaced apart from each other.

Therefore, the second guide plate 600 can alleviate the impact generated when the molded fuel F is discharged to the conveyor 80. [

In addition, the second guide plate 600 can present the direction in which the shaped coal F is conveyed so that the spherical shaped coal F can be easily transferred along the conveyor 80.

The injection device 700 can inject oil onto the briquettes F produced by the roller 200.

When the blast furnace F is charged into the blast furnace, the blast furnace F with the oil can improve the strength and quality of the blast furnace furnace and the coke oven. Here, it is preferable that the oil is provided with an oil capable of improving coke quality. As the oil, waste cooking oil may be used.

3, the jetting apparatus 700 includes a nozzle unit 710, an oil supply unit 720 and a nozzle unit 710 disposed between the suction plate 410 and the second guide plate 600, And a transfer pipe 730 disposed between the supply devices 720. [

Accordingly, the control unit 800 controls the oil supply unit 720 so that the oil is injected into the molded fuel F through the nozzle unit 710.

The nozzle unit 710 is disposed between the suction plate 410 and the second guide plate 600, and a plurality of nozzles may be disposed in the nozzle unit 710. Then, the oil can be injected into the molded fuel F through the nozzle.

As a result, the molded fuel F absorbs the oil, and the oil can prevent the molded fuel F from being broken by external impact when the molded fuel F is fed.
