Description

DUST COLLECTING APPARATUS UTILIZING ELECTROMAGNET FOR USE IN SUPPLEMENTARY RAW MATERIALS SUPPLYING SYSTEM WITH TRIPPER CAR}

The present invention relates to the improvement of the dust collector that collects the dust generated when transporting the subsidiary materials and ferroalloy into the tripper car during the blow job in the converter, in particular, the dust collection efficiency is reduced due to the gap between the dust damper and the tripper car part. The present invention relates to a subsidiary material stripper dust collector using an electromagnet to solve the problem and to facilitate the management of the damper.

In general, in the process of transporting raw materials in the steel mill, when there are no raw materials in the hearth hopper 6, the operator looks at the monitor 12 to designate the hearth hopper 6 to be transported and determines the amount of transportation to the keyboard 13. When inputting, the PLC 11 moves the tripper 4 to the hearth hopper 6, starts the belt conveyor 5, the belt conveyor 3, and the belt conveyor 2, The feeder (not shown) is started to transport the raw materials. When the belt conveyor is activated, the PLC 11 starts the motor 24 when the damper 31 of the damper unit 32 is opened, and starts the suction device 23 and the bag filter 22 to perform dust collection. The collected dust is stored in the dust collecting hopper 25 at the bottom.

However, as shown in FIG. 3A, a gap is formed between the end of the dust discharge passage on the tripper car 4 and the tip of the dust collecting path tip of the dust collecting line so as not to cause future in the movement of the tripper car 4. (M) is about 50-100mm wide and dust is not collected properly due to the suction of external air when dust is collected in this gap, so dust is transferred to the raw material inlet (6.2) on the upper hopper (6) of the lower part of the tripper (4). While flying, there is a problem that the workplace and the belt conveyor lower part is contaminated. In addition, since the cylinder 33 and the solenoid valve 34 are installed in a high place, it is difficult to manage and the repair work is difficult when the damper is broken.

The present invention was devised to solve the conventional problems as described above, by effectively collecting the dust generated during the transport of raw materials using tripper cars to prevent pollution of the work environment and equipment protection caused by dust falling inside the belt conveyor and factory. It is an object of the present invention to provide a device that can reduce the work load of the operator by eliminating the need for additional dust removal work.

Hereinafter, the present invention for achieving the above object will be described in detail with reference to the embodiments illustrated in the accompanying drawings.

As illustrated in FIG. 4 and FIG. 5, the present invention provides an electromagnet 40 on an upper portion of the tripper car 4 which transports raw materials to each hearth hopper 6, and each hearth hopper of the dust collecting line 21. 6, the head 41 is provided on the front surface of the supporting portion of each damper portion 32 provided at a position corresponding to the plurality of guides, and a plurality of guides 42 are formed on the head 41, and the inside of the head 41 has a flexible dust collector. It has a configuration in which the cover 45 is provided.

In addition, a guide hole is provided in the support portion of the damper part 32, which is a rectangular part, to allow the guide 42 to be moved. A spring 43 is installed on the rear side of the square support at the tip of the damper part 32, and a hood 44 is connected to the rear end of the guide 42. The hood portion 44 is connected to the connection portion 46 is installed between the connection portion 46 and the bearing portion 48 is connected to the auxiliary connection portion 47, the bearing portion 48 is connected to the damper 31 Has a connected configuration.

Hereinafter, the operation of the present invention configured as described above will be described.

As shown in FIG. 1, a worker first selects a raw material to be transported while looking at the monitor 12 on the keyboard 13 to set the raw material to be transported, and sets the sub-hopper hopper 6 and the ground hopper 1 to be transported. After the raw material transportation is executed, the PLC 11 first sends a signal to the tripper car 4 so that the tripper car 4 moves to the designated road hopper 6. When the tripper 4 is located in the designated road hopper 6, the PLC 11 sends a signal to operate the electromagnet 40. When the electromagnet 40 is actuated, the head 41 of the damper part 32 is pulled toward the electromagnet 40, and the flexible dust collecting cover 45 moves while the guide 42 also moves. Close to the perka 4 side, there is no gap between the tripper 4 and the dust collecting passage to prevent the intake of external air. In addition, the hood part 44 connected to the rear end of the guide 42 and the connection part 46 connected to the hood part 44 move along the guide 42, and thus the auxiliary connection part 47 is interlocked. As the damper 31 connected to the bearing portion 48 moves, the damper 31 is opened. Then, when the belt conveyors (2), (3) and (5) are started and the feeder of the ground hopper 1 is started and the raw materials are transported, the motor 24 moves and the suction device 23 is started and the bag filter 22 is operated. The dust collection starts. When the raw material transport operation is completed, the motor 24 is stopped and the starting of the suction device 23 is stopped and accordingly the PLC 11 stops the operation of the electromagnet 40. Then, the spring 43 installed along the guide 42 on the back of the rectangular support of the damper part 32 pushes the guide 42 and the hood part 44 to the original position, and thus is connected to the hood part 44. As the connecting portion 46 is pushed back, the auxiliary connecting portion 47 and the bearing portion 48 are interlocked so that the damper 31 is closed. At the same time, the head 41 and the dust cover 45 attached to the electromagnet 40 are moved back along the guide 42 so as not to cause an obstacle in the movement of the tripper 4.

Therefore, according to the present invention as described above, the dust generated when the raw material is transported by the tripper car in the steel mill more effectively to prevent working environment pollution and equipment pollution, and the cylinder that was conventionally installed and used for the operation of the dust damper And by removing the equipment such as the solenoid valve and the damper is moved by the device that is operated during the dust collection, the practical effect is obtained to improve the device configuration and facilitate the equipment management.
