Description

Deflection device of extruder leveler {Apparatus of hanging prevention for leveler of pusher car}

The present invention relates to an apparatus for preventing sag of an extruder leveler, and more particularly, to an apparatus for preventing the leveler from sagging by its own weight while supporting the leveler.

Coke, which is generally used as a means of ensuring heat permeability with the role of heat source and reducing agent in the carbonization chamber, is manufactured by carbonizing the coal in the carbonization chamber. Charged car for injecting coke, the extruder for extracting the dry coke is dried on the side of the oven, and the transfer car for moving the red coke withdrawal is located on the outlet side of the oven is equipped with coke coke When extruded from the oven, the charge is charged into the interior of the coke oven by the charging vehicle installed to run on the top of the coke oven, and dried so that the coke can be continuously produced every predetermined time using an extruder and a transfer car.

At this time, the call is charged into the coke oven every time by using a charging vehicle, and the coke is driven by a leveler which is mounted on the extruder to move forward or backward in order to eliminate the mountain-shaped bend generated every time the call is charged into the coke oven. A leveling operation is performed in which the top of the call charged into the oven is flattened.

As described above, the leveler is pushed into and taken out of the coke oven to flatten the call accumulated in the oven, thereby facilitating the flow of gas generated in the carbonization chamber.

However, in the related art, the front part of the leveler enters the carbonization chamber side, and sag occurs due to its own weight, so that the flatness of the call by the leveler is poor. In addition, when the leveler, which has a problem that causes a gas accident due to a poor planarization of a call and causes a droop, is removed from the carbonization chamber, a call in the carbonization chamber is drawn to contaminate the surroundings of the carbonization chamber.

The present invention is provided in an extruder (2) for drawing a coal (4) in the carbonization chamber (3), to be used in a leveler (5) to planarize the call (4) charged in the carbonization chamber (3). It is about a device that can. That is, since the leveler 5 inserted into the carbonization chamber 3 has a long shape compared to the length of the other side, only one side is supported by the extruder 2, and the carbonization chamber 3 The other side inserted into it is not supported. Accordingly, the leveler 5 inserted into the carbonization chamber 3 has a problem of sagging in the direction of gravity due to its own weight. In order to solve this problem, the present invention provides the buffer means 200 and the deflection prevention means 100 to prevent the deflection of the leveler 5.

Accordingly, there is an effect that can prevent the poor planarization of the call 4 in the carbonization chamber 3 and to prevent the gas flow in the carbonization chamber 3 is blocked, it is possible to prevent equipment accidents.

The deflection preventing means 100 serves to prevent the deflection of the leveler 5 by supporting the leveler 5 when the leveler 5 deflects in the gravity direction due to its own weight. That is, the structure supporting the leveler 5 is provided to prevent the leveler from sagging. To this end, the deflection prevention means 100 may include a center tab 120, the support plate 130 and the support roller 110.

The center tab 120 serves to connect the shock absorbing means 200 and the deflection preventing means 100. In this case, the deflection preventing means 100 may be connected to the buffer means 200 to be rotated at a predetermined angle.

The support roller 110 is coupled to both ends of the support plate 130 to which the center tab 120 is coupled to serve to support the leveler 5. That is, when the leveler 5 is seated on the support roller 110, the support plate 130 rotates at a predetermined angle about the center tab 120, and the leveler through the support roller 110. (5) will be supported. The support roller 110 may have a cylindrical shape or a janggu shape. This will be described later with reference to FIG.

The deflection prevention means 100 prevents the deflection of the leveler 5 by a seesaw operation, which is possible by allowing the center tab 120 to rotate the support plate 130.

At this time, the rear end supporting roller 112 is the leaflet roller 111 by the movement (M1) to the lower side, the support plate 130 by the operation (M3) to rotate around the center tab 120 It moves upward (M2).

Thus, the rear end supporting roller 112 is in contact with the leveler 5, by applying a pushing force (F2) to the leveler 5, thereby preventing and supporting the bending of the leveler (5). In addition, as the leaflet paper roller 111 also supports the leveler 5 as the rear end supporting roller 112 no longer moves downward, the reaction of the force F1 that the leveler 5 presses downward. By applying a force (F2) for supporting the support roller 110. However, since the upper support roller 110 and the rear support roller 112 apply the same force to the leveler 5 with respect to the center tab 120, the leveler 5 is applied with the same force F2. Support. At this time, the buffer means 200 connected to the center tab 120 serves to cushion, which will be described later.

On the other hand, when the inserted leveler (5) is reversed and exit from the deflection prevention device (1) of the extruder leveler, the leaflet paper roller 111 is able to move upward again (M1), the rear end supporting roller 112 may be moved downward (M2).

The leaflet paper roller 111 is located above the lower support roller 110, it is preferable to contact the leveler 5 than the lower support roller 110. To this end, the support plate 130 may be configured to be inclined toward the rear end supporting roller (112).

As a first embodiment of the configuration, the weight of the leaflet paper roller 111 can be configured to be smaller than the weight of the lower support roller 110. That is, since the leaflet paper roller 111 is lighter than the lower support roller 110, when the leveler 5 is not inserted, the leaflet paper roller 111 is smaller than the rear end roller 112. It is located on the upper side.

In addition, as a second embodiment, there may be a configuration in which the center tab 120 is coupled to the support plate 130 closer to the leaflet paper roller 111 than the rear end supporting roller 112.

The trolley 310 is coupled to the shock absorbing means 200, and serves to move the shock absorbing means 200. In addition, the wheel 330 may be coupled to the lower side to facilitate movement, and may be combined with the housing 400 to be described later to form a closed cross section.

The transfer cylinder 320 serves to transfer the deflection prevention device 1 of the extruder leveler back and forth. To this end, one end of the transfer cylinder 320 may be coupled to the trolley 310 or the housing 400 to be described later. In addition, the other end of the transfer cylinder 320 is coupled to the support member 7 of the extruder 2 to serve as a support point during the transfer of the deflection prevention device 1 of the extruder leveler. The transfer cylinder 320 may be configured using a hydraulic cylinder, an air cylinder or a motor. However, the present invention is not limited thereto, and the transfer cylinder 320 of the present invention may be provided if the deflection preventing device 1 of the extruder leveler can be transferred back and forth.
