The present invention relates to an automatic opening and closing device of the riser lid, and more particularly, the charging operation during the charging of the coal and the extruding of the gas in the coke oven carbonization chamber opens the riser lid when the dry coking of the coke is completed and extruding the gas. This is when the coal is charged into the oven carbonization chamber through the charging inlet, and the riser lid automatic opening and closing device for closing the riser lid completely without damage by the lever operating device of the charging vehicle.

In general, as shown in Figures 1 to 3, the riser lid opening and closing device is a riser tube lid 4a for opening and closing the riser tube 3 installed in the carbonization chamber (2), and a water jacket (circle) 11), a cylindrical case 22 which is connected to and rotated through the lead connecting member 4b to the riser lead 4a, a rod shaft 7 connected to one side thereof, and perpendicular to the rod shaft 7 The cover lever 10 is connected to the upper and lower operation, and the weight 6 attached to the middle of the cover lever 10.

The riser lid opening and closing device configured as described above closes the riser lid 4a by the operation of the cover lever 10 at the time of extruding the gas before the charging operation of coal.

At this time, if the riser lead 4a is not completely closed but is less closed, it is completely closed by the weight 6 located in the middle of the cover lever 10.

As described above, after the riser lead 4a is closed, the gas generated inside the carbonization chamber is discharged through the gas collection transfer pipe 5.

However, the conventional riser lid opening and closing device operated as described above is operated by the cover lever, and when the riser lid is completely closed by the weight attached to the lever, the water jacket and the riser lid are damaged by the impact of the weight. And, the inhalation of air through the broken riser lead may cause explosion in the carbonization chamber, thereby causing a problem that the harmful gas is discharged.

In order to solve the above problems, the present invention allows the riser lead to be completely closed by the weight when closing the riser lead to shut off the gas discharged during the extrusion operation of the coal before charging the coal into the coke oven carbonization chamber. In this case, to prevent the breakage of the riser lead by controlling the flow rate of the fluid applying the orifice principle in order to prevent the top tube lead from being damaged by the weight impact to provide a riser lead automatic opening and closing device There is this.

 In order to achieve the above object, the present invention is a cylindrical case which is connected to the rising pipe lead for opening and closing the rising pipe installed in the carbonization chamber, the water jacket is installed around it, and is connected to the rising pipe lead through a lead connecting member to rotate And a rod shaft connected to one side thereof, a cover lever vertically connected to the rod shaft to operate up and down, and a lift tube lid opening and closing device attached to a middle of the cover lever, the inside of the cylindrical case Rotary inserted and rotated, a spring shaft provided on the outside of the rotary, an oil ring attached to both sides of the rotary to prevent the leakage of fluid, and a case cover provided on both sides of the rotary case is fitted to both ends of the cylindrical case And a bearing provided at both sides of the case cover to smoothly rotate the rotary. It provides a riser leads to the automatic opening and closing apparatus.

In addition, the inner side of the spring shaft is provided with a passage through which the fluid flows, it provides a riser tube lead automatic opening and closing device characterized in that the ball and the spring is provided to control the flow rate of the fluid in one passage.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the present invention.

As shown in Figure 6 and 8, the riser lid automatic opening and closing device according to the invention is inserted in the inner center of the cylindrical case 22 so that the rotary 30 is rotated.

A spring shaft having a ball 27 for adjusting the flow rate of the fluid when the fluid passes through the rotary 30 and a spring 28a attached thereto to open and close the flow of the fluid into the ball 27. 28b) is attached.

One side of the rotary 30 is provided with oil rings (33a, 33b) to prevent the leakage of the fluid, one side thereof is attached to the case cover (29) covering the cylindrical case (22).

In addition, a bearing 32 for smoothly rotating the rotary 30 is provided at one side of the case cover 29, and oil chambers 31a and 31b at one side thereof are provided to block leakage of the fluid.

In addition, one side of the oil chamber (31a, 31b) is inserted into the split pin 20 to facilitate the division of the riser lid automatic opening and closing device is fixed to the gear shaft (26).

On the other hand, the other side of the rotary 30 is provided in the same manner as described above is attached to the rod shaft (7).

Hereinafter, the operation of the present invention will be described in detail.

As shown in FIG. 3, the riser lid 4a starts to close by the rotation of the cover lever 10, and is completely closed by the weight 6.

At this time, as shown in Figure 4, when the riser lead (4a) is closed horizontally, the rod shaft 7 is rotated from a to a 'as shown in Figure A of Figure 7, the fluid 23 is shown As the B flows from the right side to the left side, the tube b formed on the spring shaft 28b passes the fluid well, and the tube c is blocked by the action of the ball 27 by the spring 28a so that the fluid 23 does not pass. can not do it.

As described above, when a part of the flow rate of the fluid 23 is blocked and the passage amount of the fluid 23 is limited, the riser lead 4a is gradually closed to prevent breakage due to the impact.

On the contrary, as shown in FIG. 5, when the riser lead 4a is opened, the rod shaft 7 rotates from a 'to a as shown in FIG. 7A, and the fluid 23 is shown in FIG. Likewise, the tube b formed on the spring shaft 28b flows from left to right, and the fluid passes well, and the tube c also opens while the ball 27 attached to the spring 28a is pushed backward so that the fluid 23 passes well. do.

As described above, when the passage amount of the fluid 23 increases, the return tube lead 4a is easily returned, and the riser lead 4a is easily opened.

As described above, the automatic riser lid opening and closing device according to the present invention is an impact when the riser tube is closed when the riser lid is open-closed by using a charging vehicle for charging coal and extruding gas after coking coking. It has a significant effect in preventing the damage of the upstream pipe fittings caused by the damage and extending the service life of the equipment and preventing the pollution caused by the gas explosion in the carbonization chamber caused by the equipment damage.
