The present invention relates to a charging inlet device, and in particular, in the process of charging bituminous coal in a carbonization chamber, the opening and closing operation of the charging inlet lead can be improved to improve work efficiency, and to prevent environmental pollution and equipment accidents. It relates to a cover-type charging lead of the device.

1 is a perspective view showing a lead lifter for a conventional charging lead opening, FIG. 2 is a side view showing a charging vehicle for charging bituminous coal into a carbonization chamber, and FIG. 3 is a schematic perspective view showing a general drop sleeve, and generally a carbonization chamber of a coke oven. In the operation of charging bituminous coal into the lead, after the lead lifter 85 installed in the charging vehicle is moved forward and down, the charge lead (by the magnet 88 provided at the lower end of the lead lifter 85). After the 89 is opened, when the drop sleeve 81 is down, bituminous coal charging is performed.

The lead lifter 85 installed in the charging vehicle is composed of a total of 12 cylinders such as a forward and backward cylinder, a lifting cylinder, a charging inlet revolving cylinder, and a facility in which a lot of fire risks are potential, such as a magnet 88 and a limit switch cable. to be.

In this case, in the conventional lid lead open lead lifter 85, when a large amount of gas and flames are leaked to the outside due to the gap between the drop sleeve 81 and the charging slot frame 20, equipment damage and environmental pollution are caused. In the event of an emergency (such as an electrostatic accident), the four drop sleeves 81 are up and the four charging leads 89 are crossed at least one minute. There was a problem that a large amount of flames and gases generated are delivered to the charging vehicle leading to a large fire accident.

In the drawings, reference numeral 82 and 83 are cylinders.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to reduce the damage to the facility and environmental pollution by preventing the leakage of gas or flame generated when the bituminous coal is charged, and to prevent the safety hazard of workers In addition, the present invention provides a lid-type charging lead lid device for a coke oven that can improve the quality of a product coke by reducing a charging time.

In order to achieve the above object, a lead lifter is installed in a charging vehicle, a charging lead is opened by a magnet installed in the lead lifter, and a device for charging bituminous coal into a carbonization chamber of a coke oven by dropping down a sleeve. A rotating part comprising a shaft and a magnet plate coupled to the shaft, the rotating part being installed in the carbonization chamber through first and second supporting means; A cover-type lead portion provided in the second support means; There is provided a cover-type charging lead lid device for a coke oven comprising a cylinder and an operation unit for rotating the rotating unit by a magnet connected to the cylinder.

In the present invention, the cover-type lead portion is characterized in that it comprises a lead body provided with a connection bracket, and a heat sink coupled to the inside of the lead body.

In addition, in the present invention, the drop sleeve is characterized in that the circular cover having a hollow portion is mounted.

Hereinafter, the present invention will be described in more detail with reference to the drawings showing preferred embodiments.

4 to 7 show an embodiment of a cover type charging device for a coke oven according to the present invention, and the charging device according to the present invention includes a rotating part installed in the carbonization chamber through first and second supporting means. ; A cover-type lead portion provided in the second support means; It consists of an operation unit for rotating the rotating unit.

The first support means has a lead base 30 coupled to a nut 32 to a weld bolt 31 protruding from the inside of the carbonization chamber 10, and a guider 33 is integrally formed on the lead base 30. It is formed.

The second support means has a lower portion of the support 50 seated in the guider 33, and the rivet 51 penetrates through the connecting bracket 65 of the lead body 60, which will be described later, and is coupled to the pin 52. have.

The rotating part has a bolt-shaped connecting shaft at the bottom of the magnet plate 41 in a nut-shaped groove 40-1 formed in the shaft 40 having a predetermined length passing through the supports 50; 50a to 50d and the guider 33. 42 is coupled via nut 43 and washer 44.

The cover type lead part is integrally formed with a connecting bracket 65 for connecting the rivet 51 to the rear part of the lead body 60 (60a to 60d), and the heat sink 61 of the lead body 60 The bolt 62a which penetrates the support plate 63 integrally formed in the said heat sink 61 (61a-61d) inside, and is couple | bonded with the nut 62b.

The magnet 71 is fixed to the cylinder rod distal end of one cylinder 70 provided in the charging unit.

On the other hand, the drop sleeve 81 has a circular cover 80 having a hollow portion is mounted through the support plate 80-1, the support plate 80-1 is a cylinder through the connecting shaft (80-2) It is connected to the 84, the up and down of the circular cover 80 by the cylinder 84 is made.

Hereinafter, the operation of the present invention having the configuration as described above.

As shown in FIGS. 4 to 7, when the circular cover 80 installed outside the drop sleeve 81 of the charging vehicle is down through the cylinder 84, the cylinder 70 moves forward and the magnet 71 moves forward. When the magnet 71 pulls the magnet plate 41, the magnet plate 41 rotates counterclockwise by the rotation of the shaft 40.

At the same time, the lead body 60 connected to the shaft 40 is also rotated counterclockwise while the four lead bodies 60 are simultaneously opened from the charging frame 20; 20a to 20d. After dropping the drop sleeve 81 of the charging vehicle in the same state, charged coal is charged into the carbonization chamber.

On the other hand, after the loading of the coal briquettes is completed, when the cylinder 70 reverses as described above, the magnet plate 41 rotates in the clockwise direction while the contact between the magnet 71 and the magnet plate 41 is broken, and at the same time, Since the lead body 60 is also rotated in a clockwise direction, four lead bodies 60 are closed at the charging frame 20 at the same time, thereby reducing work time and process.

At this time, the heat dissipation plate 61 protects the lead body 60 from high heat inside the circular cover 80 installed outside the drop sleeve 81, and also prevents outflow of toxic gas such as COG (Coke Oven Gas). do.

On the other hand, when the shaft 40 is divided into four to be assembled, disassembly and assembly is easy, and maintenance work or replacement of the cover type lead part can be performed more easily.

As described above, according to the present invention there is an effect that the equipment damage or environmental pollution due to the outflow of gas and flame is prevented, and the safety accident of the operator is reduced.

In addition, there is an effect that can prevent the occurrence of large-scale fire by reducing the work process and time.
