However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you. Wherein like reference numerals refer to like elements throughout.

Figure 2 is a view showing a cross-sectional view of the red coke extrusion block processing apparatus according to an embodiment of the present invention, Figure 3 is a view from the top of the red coke extrusion block processing apparatus according to an embodiment of the present invention, Figure 4 According to an exemplary embodiment of the present invention, the red coke crushed at the front end of the screw bar is transferred to the rear end of the screw bar along the screw in the form of a screw thread.

Glowing coke extrusion molding processing apparatus according to an embodiment of the present invention includes a screw bar 110, a screw rotation drive body 120, forward and backward drive member 130, the receiving container 140.

The screw bar 110 is in the form of a bar of a columnar body, and the screw of the protruding screw line 111 is formed in the outer diameter of this columnar body. When the screw bar 110 advances, the screw 111 protruding from the outer diameter of the screw bar rotates to crush the cohesive red coke that is aggregated and aggregated near the door of the coke oven. As illustrated in FIG. 4, the glowing coke crushed at the front end of the screw bar 110 is transferred to the rear end (rear) of the screw bar 110 along the screw 111 in the form of a thread. Since the screw formed in the outer diameter of the screw bar has a protruding screw thread structure, the crushed red coke is loaded into the valley of the screw thread and moved to the rear end of the screw bar.

The screw 111 is rotated by the screw rotation driver 120. The screw rotation drive body 120 includes a screw spur gear 123, a drive spur gear 122, and a screw hydraulic motor 121. When a rotational force generated by the hydraulic pressure in the screw hydraulic motor 121 is generated by the user's manipulation, the driving spur gear 122 connected thereto rotates. Accordingly, the rotation of the screw spur gear 123 engaged with the driving spur gear 122 occurs, and the screw bar 110 coupled to the screw spur gear 122 rotates. For reference, the hydraulic pressure provided to the screw hydraulic motor 121 is supplied from the hydraulic pump to control the direction by the electromagnetic displacement.

In addition, the longitudinal shear of the screw bar 110 is provided with a rotary blade 113 in the form of a cone. The rotary blade 113 has a sharp cone shape, so that the screw bar 110 is easily moved forward when the screw bar 110 is advanced into the coherent red coke in the coke oven. The rotary wing 113 may have a variety of shapes in addition to the cone shape, if there is a form that can crush the aggregated coke coke will not be limited in form.

In addition, the screw bar 110 has a hollow inside the center of the longitudinal axis is empty, the cooling water pipe 112 is provided in the hollow inside. Cooling water is supplied to the cooling water pipe 112 formed inside the hollow of the screw bar 110 to allow the cooling water to circulate along the cooling water pipe. Due to the coolant circulation in the coolant pipe 112, the surface temperature of the screw bar 110 surrounding the coolant pipe is lowered. Thus, the temperature of the glowing coke is lowered by the cooled screw bar 110 that digs and advances the glowing coke. The cooling water supply unit (not shown) supplied to the cooling water pipe 112 receives the cooling water from the outside and provides the cooling water inside the cooling water pipe. The cooling water is not limited to water, and any type of cooling water is not limited. .

On the other hand, the cooling water pipe 112 is embedded in the hollow in parallel along the central axis of the longitudinal direction of the screw bar, along the hollow interior of the screw bar (110). The embedded form of the cooling water pipe is not limited thereto, and the cooling water pipe may be embedded in a zigzag form along the inner hollow of the screw bar.

The forward and backward driving member 130 serves to back and forth the screw bar in the longitudinal direction. That is, coupled to the rear end in the longitudinal direction of the screw bar 110, when operating in the forward mode to drive the screw bar 110 to move forward by moving forward, when operating in the reverse mode to reverse the screw bar 110 Pull back To this end, the forward and backward driving member 130 includes a pinion gear 133 which is a rotating gear, a plate bar beam 131 having a rack gear 132 meshed with the pinion gear 133 on an upper surface thereof, and the beam. It includes a stand roller 135 for supporting and rolling the lower surface of the.

The forward and backward driving member 130 has a structure in which the plate bar has a structure in which the beam 131 is moved forward and backward, and the rack gear 132 in the form of a flat toothed gear is formed on the upper surface of the beam 131 along the bottom of the upper surface. It is formed in the longitudinal direction of the beam 131.

In addition, a pinion gear 133 which is a rotational gear is formed while being spaced apart from the upper portion of the beam 131. The pinion gear 133 is driven to rotate about the central axis of the pinion gear 133 by the hydraulic force provided from the forward and backward hydraulic motor 134. The pinion gear 133 and the rack gear 132 are meshed with each other, and the forward and backward movement of the rack gear 132 occurs in accordance with the rotation of the central axis of the pinion gear 133. Accordingly, the beam 131 to which the rack gear 132 is coupled is moved forward and backward as the rack gear 132 moves forward and backward. As the beam 131 moves forward and backward, the screw bar 110 coupled to the front end of the beam also moves forward and backward.

The lower surfaces of the screw bar 110 and the beam 131 are provided with a plurality of stand rollers 135 supporting the screw bar and the beam, respectively. The stand roller 135 supports the bottom surface of the bottom of the screw bar or the beam when the forward or backward movement of the screw bar or the beam is performed without a separate rotation driving force, so that the free rolling is performed.

On the other hand, when the forward and the reverse is made, there is further provided with a sensing device to prevent the advance and the reverse more than a predetermined. When the advance of the screw bar 110 is sufficiently made so that it is no longer necessary to crush the agglomeration of the red coke in the coke oven, it is to detect this to return to the original position by reversing the screw bar.

To this end, as shown in FIG. 3, the touch bar 151 protruding in the thickness direction of the beam, a forward detecting sensor 152 for detecting the forward of the touch bar, and a backward detecting the touch bar. And a reverse detection sensor 153. The touch bar 151 has a bar shape protruding in the thickness direction of the beam 131. Therefore, when there is a forward and backward of the beam, the touch bar 151 also moves forward and backward together.

The advance detection sensor 152 is installed on a separate device spaced apart from the beam without being installed on the beam, and is installed at a position parallel to a specific point of the front end portion of the beam so that no further forwarding occurs. Accordingly, the touch bar 151 is advanced by the advancement of the beam 131, so that the touch bar 151 contacts the forward detection sensor 152, so that the beam is advanced to a specific position.

The reverse detection sensor 153 is also installed on a separate device spaced apart from the beam without being installed on the beam, and is installed at a position parallel to a specific point of the rear end in the longitudinal direction of the beam so that no further reverse occurs. Accordingly, since the touch bar 151 is moved backward by the backward movement of the beam 131, the touch bar 151 contacts the backward detection sensor 153, so that the backward position of the beam can be determined. For reference, when the reverse of the beam is detected by the reverse sensor 153, the original return operation such as the rotation stop of the screw bar and the cooling water circulation stop.

The storage container 140 is a container for storing the glowing coke crushed and dropped by the advance of the screw bar 110.

The glowing coke crushed at the front end of the screw bar 110 is conveyed to the rear end (the tail) of the screw bar 110 along the protruding screw thread. Since the screw formed in the outer diameter of the screw bar has a protruding screw thread structure, the crushed red coke is carried in the valley of the screw thread and is transferred to the rear end of the screw bar. The glowing coke moved to the rear end of the screw bar as described above is dropped from the rear end of the screw bar, as shown in Figure 4, so that the falling red coke is contained in the storage container 140.

The storage container 140 includes a hopper 141 which is a columnar body which is positioned below the screw bar and is opened up and down, and a lower gate 142 that opens and closes the open surface of the lower portion of the hopper. The hopper 141 located at the bottom of the rear end of the screw bar is open at the upper part thereof and receives the glowing coke falling through the screw through the open upper part. The bottom of the hopper is also open, but the open bottom surface of the hopper is blocked by the bottom gate 142. The lower gate 142 is maintained horizontally or vertically by the hydraulic cylinder 143. When the lower gate 142 is in a horizontal state and closes the lower open surface of the hopper 141, the red coke is contained in the hopper. On the other hand, when the lower gate 142 is in a vertical state to open the lower open surface of the hopper 141, the red coke contained in the hopper is carried out to the truck under the hopper.

In addition, the inner surface of the upper end of the hopper 141 is provided with a spraying nozzle 144 for extinguishing the high-temperature state of the red coke, the high temperature state of the red coke by the coolant sprayed into the hopper through the spraying nozzle 144 Lowers

On the other hand, between the hopper 142 and the screw bar 110 is provided with a coke plate 150 in the form of plate plate containing the falling red coke. The coke receiving 150 has a semicircular shape in which the surface of the plate plate is bent downward, so that coke may be contained in a semicircular space. The coke receiving 150 has a form in which the front surface of the front end is inclined, so that the coke receiving can be easily seated into the cohesive red coke in the coke oven.

The coke receiving 150 is formed in the lower portion of the screw bar in parallel to the screw bar, the inclination of the longitudinal direction of the coke receiving 150 is implemented to be inclined. This is to allow the glowing coke contained in the front end of the coke receiving flows to the rear end of the coke receiving along the inclined slope.

The length of the coke receiving 150 is formed to be shorter than the length of the screw bar (110). Since the length of the coke receiver 150 has a length shorter than that of the screw bar 110, there is a portion in which the coke receiver is not provided between the screw bar and the hopper. The portion where no coke receiver is present is formed at the rear end of the screw bar. Therefore, the glowing coke falling from the rear end (the tail) of the screw bar 110 is directly contained in the hopper 141 through the portion without the coke receiving.

Hereinafter, an operation process of the coke extrusion blockage treatment apparatus having the above-described structure will be described with reference to FIGS. 5, 6 and 7.

5 is a view showing a screw bar provided in the extruder according to an embodiment of the present invention to advance the crushed red coke clogged at the inlet of the coke oven to put in the hopper, Figure 6 is a touch bar by the forward detection sensor As illustrated, the screw bar is retracted as it is detected, and FIG. 7 is a view showing the red coke contained in the hopper falling through the open lower part.

In the coke oven (10), the extruder removes the door to advance the dry distilled coke, and the ram is advanced and extruded into the coke into the tank bucket. The coke is not shrunk due to the collapse of the hopper sticking coal. May occur.

In this case, after the ram of the extruder is retracted, the coke receiver according to the embodiment of the present invention is aligned with the door inlet of the coke oven.

By pressing the forward button of the cab to start the screw hydraulic motor 121 and the forward and backward hydraulic motor 134, the screw bar 110, the screw of the screw thread is rotated to advance. That is, when the forward button of the cab is pressed, the pinion gear 133 is rotated by the forward and backward hydraulic motor 134, and thus the beam 131 is advanced by the rack gear 132 engaged therewith, as shown in FIG. As such, the screw bar is in contact with the glowing coke located on the door of the coke oven. In addition, the water pump is operated to circulate the cooling water inside the hollow of the screw bar.

When the red coke condensed by the sharp blade and the rotary wing of the front side of the coke receiving block 150 is crushed and collapsed and placed on the screw thread of the screw, the red coke is moved to the rear end (back) by the rotation of the screw. The red coke transferred to the rear end of the screw bar 110 is loaded into the hopper 141. At this time, the glowing coke loaded on the hopper is extinguished by the spraying nozzle 144.

When the coke oven's glowing coke is blown out by the screw to some extent (about, about half), the screw bar is placed in the forward position, and the touch bar 151 installed on the screw bar touches the forward detecting sensor. When the forward detecting sensor is touched, the forward and backward hydraulic motor rotates in reverse, the pinion gear 133 rotates in reverse, and the beam is reversed. As shown in FIG. 6, the screw bar 110 and the beam 131 are removed from the coke oven. Comes out.

When the beam 131 is fully retracted and the touch bar 151 touches the backward detecting sensor, the forward and backward hydraulic motor 134 is stopped to stop the reverse, and the screw hydraulic motor 121 is stopped to stop the screw bar 110. It also stops the rotation, and also stops the cooling water circulation circulating in the hollow inside of the screw bar (110).

On the other hand, when the hopper 141 is filled with the coke, as shown in Fig. 7, the lower gate 142 is opened to drop the coke to the lower truck to take it out.

Although the present invention has been described with reference to the accompanying drawings and the preferred embodiments described above, the present invention is not limited thereto but is limited by the following claims. Accordingly, those skilled in the art will appreciate that various modifications and changes may be made thereto without departing from the spirit of the following claims.
