Description

Solid material removal device of compounding material cutting device {APPARATUS FOR REMOVING A CLUGGING SOLID IN DISCHARGING SYSTEM}

The present invention relates to a device for removing a solid fluorescence jam, when solid fluorescence is introduced in the process of cutting the blended raw material from the raw material hopper to the trolley during the sintering operation, when the jam occurs in the lower part of the raw material hopper, it automatically detects and crushes it. It relates to a solid fluorescence jam removal device of the drum feeder to ensure the cutting process.

In general, the sintering industry refers to a process for producing sintered ores by sintering iron ore, limestone, serpentine, and other raw materials, and a blended material of coke and semi-ore as a fuel source. That is, in the charging device of the sintering machine, the blending raw material is charged from the blending raw material supply tank onto the sintering cart, and the sintering layer is ignited by an ignition furnace located at the top of the sintering layer in which the blending raw material is charged. It refers to a sintering process in which air is sucked through a located ventilator to agglomerate particles in the sintered bed.

Figure 1 shows a cutting device of the sintering blended raw materials used in the sintering industry. Referring to Figure 1, the following describes the process of cutting the blended raw material. In the raw material hopper 1, the blended raw material is supplied to the drain plate 8 by the rotation of the drum feeder 6, and is extracted on the sintered trolley 9 along the drain plate 8. The amount of cutting of the blended raw material according to this method is controlled by the rotational speed of the drum feeder 6, and finely adjusts the gate 7 by the power of the servo drive 5 and can also be locally controlled.

In this case, the blended raw material loaded in the raw material hopper 1 contains water and may be fixed between the blended raw material particles while the water evaporates, or may be fixed to the inner wall of the raw material hopper when stagnated for a long time. Such fixed blended raw materials can form large particles of solid fluorescence. Such solid fluorine compounding material is not caught by the gate 7 at the bottom of the raw material hopper during cutting and prevents the cutting of other compounding raw materials.

As a result, a portion (A) in which the amount of cut of the blended raw material is reduced is generated on the sintered trolley (9), and the ventilation provided from the ventilator (not shown) is concentrated in the portion so that the sintering temperature distribution is not uniform. Becomes poor. In addition, such a problem occurs, and it takes a considerable time to remove the solid fluorescence, there is a problem that there is a safety risk in the removal process.

In order to solve the problems as described above, an object of the present invention is to provide a solid fluorescence removal device that detects the cutting failure by the solid fluorescence immediately and automatically removes it in order to smoothly discharge the blended raw materials.

Hereinafter, the present invention will be described in detail with reference to the drawings. Referring to Figure 2, there is shown a blending raw material charging device implemented in a solid jam removing device according to an embodiment of the present invention.

The compounding raw material charging device of FIG. 2 (a) operates in the same manner as the charging device of FIG. 1 except for the solid jam removal device. In the description of FIG. 1, overlapping portions will be omitted. The solid object jam removing device according to the temporary form of the present invention includes a reference cut amount setting unit 20, a cut amount detecting unit 30, a comparison unit 40, an optional power supply unit 50 and a solid grinding unit 60. It is.

The cut-out detection unit 30 includes a plurality of detection plates 31 connected to the shafts 31 mounted on both side walls of the side chute, a plurality of cut-off measuring devices 39 for detecting the cutting height of the blended raw material, It consists of a link unit 35 connecting the detection plate 31 and the cutting amount measuring device 39. The detection plate 31 may be mounted side by side on the shaft 33 connected to both side walls of the side chute so that one side thereof may be rotatable according to the compounding material cut out on the side chute.

Referring to Fig. 2 (b), the cutaway amount detecting unit will be described in more detail. The link unit 35 is formed of a multi-link including a first link 35a and a second link 35b, the other side of the detection plate 31 and one side of the first link 35a, the first link ( The other side of the second link 35b, one side of the second link 35b, the other side of the second link 35b, and the connection portion s of the cut-off meter 39 are hinged. Therefore, the link unit 35 converts the rotation of the detection plate according to the change in the cutting amount of the blended raw material to the connecting portion s of the cutting amount measuring unit 39 and transmits the rotation. The cutting amount measuring unit 39 may measure the cutting amount of the blending raw material by obtaining the current cutting thickness information of the blending raw material by the degree of rotation generated at the second link 35b and the connecting portion s. The operation principle of the cutaway detection unit 30 will be described in detail below.

The cutting amount measuring device 39 converts the cutting thickness of the blended raw material into the cutting amount as described above and transmits the cutting amount to the comparing unit 40. The comparing unit 40 receives the reference cutting amount during normal operation set in the reference cutting amount setting unit 20 together with the actual cutting amount, and compares each other. When the actual cutting amount is smaller than the normal cutting amount, the solid grinding signal Generates.

As such, in the present invention, the method of detecting a solid jam may be determined by reducing the amount of the blended raw material cut out on the side chute. This takes into account that when the large particles of solids generated in the raw material hopper are caught by the gate, the amount of cut of the blended raw material is reduced and thus becomes smaller than the set normal amount of cut. Therefore, when the actual cutting amount is smaller than the standard cutting amount, the comparison unit 40 generates a solids pulverization signal and transmits it to the power supply unit 50.

The power supply unit 50 operates by providing power to the solid grinding unit 60 when receiving the solid grinding signal. The solids pulverization unit 60 is mounted on both sides of the raw material hopper and the cylinder portion 61 provided with a piston 63 for performing the lifting movement by receiving power from the power supply unit 50, and the pistons on both sides (63) It consists of the fixed shaft 65 which connects the upper part, and the some window 67 for crushing the solid substance which was attached directly under the said fixed shaft 65, and generate | occur | produced in the gate part. As such, the solid crushing unit 60 may be operated by reciprocating the plurality of windows 67 up and down by using the lifting movement of the cylinder unit 61. As a result, the solids stuck to the gate can be pulverized and smooth cutting of the blended raw material can be achieved.

As described above, the solid matter removing device according to the embodiment of the present invention detects the amount of the blended raw material discharged onto the site chute through each gate by the cut-out detection unit 30 provided with the detection plate 31. This is compared with the normal cutting amount set in the reference amount setting unit 20, and when the actual detection amount is smaller than the set normal cutting amount, it is determined that the solid is blocking the gate to generate a solid grinding signal, and to the solid grinding signal The solids pulverization unit 60 is operated by the power supplied accordingly, thereby pulverizing the solids, thereby achieving smooth cutting of the blended raw material.

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

3 is a schematic diagram for explaining the operation of the cutaway amount detecting unit 30 constituting the present invention. The link unit 35 of the cutoff detection unit 30 shown in FIG. 3 illustrates a multi-link including a first link 35a and a second link 35b. The detection plate 31 is connected to the fixed shaft 33 connecting the two side walls of the side chute, the one side is in contact with the compounding raw material, and rotates up and down in accordance with the cutting thickness according to the amount of cut per hour. This rotational motion is transmitted to the first link 35a and the second link 35b which are hinged to each other to generate a rotational motion at the connection portion s of the cutaway measuring device 39. That is, as shown in Fig. 3 (a), when the solid matter is generated in the gate and the cutting amount decreases as shown in Fig. 3 (b), the cutting thickness of the blended raw material decreases, thereby reducing the detection plate 31. The position is rotated downward, and this rotation is transmitted to the first link 35a and the second link 35b hinged to the other side in order to rotate the connecting portion s of the cutaway meter 39 counterclockwise. . This counterclockwise rotation indicates a decrease in the amount of cutout. The cutting amount measuring device 39 transmits the cutting amount information reduced to the degree of rotation to the comparing unit 40.

The link unit 35 of the cutout detection unit 30 detects the cutoff amount by detecting a position at which the multi-link including the first link 35a and the second link 35b and the detection plate operate according to the rotation amount. Although it is composed of a cut-off measuring device 39, it is possible to replace the rotation according to the cutting thickness of the detection plate with another link portion formed to transmit the cut-off detector. For example, it may be replaced by a cutout measuring instrument that can detect the cutoff amount according to the single link and the vertical motion of the single link.

Set the value equal to or slightly smaller than the value amplified through 10). After setting the reference cutting amount in this manner, the cutting device control circuit unit A15 turns on the drum feeder switch and rotates the drum feeder to start the cutting operation. The amount of the blended raw material actually being cut is detected by the actual cut amount detecting circuit unit A30 and transmitted to the comparison circuit unit A40.

In the comparison circuit unit A40, when the at least one actual cutting amount is smaller than the reference cutting amount by the operation of the OR gate 0R1 compared with the value of the reference cutting amount setting circuit unit 20, the high value is set to the AND gate AD1. Send a high signal. In the AND gate AD1 receiving the high signal, the dream feeder is in operation, thereby supplying a power signal to the power supply circuit unit A50 to supply power to the solid material grinding unit 60. In particular, the timers TM1 and TM2 of the power supply circuit unit A50 perform a function of causing the grinding operation of the solid material grinding unit 60 to operate at regular intervals.

The control circuit of the present invention further includes a failure generation processing circuit portion A70. When the failure generation processing circuit unit A70 is operated by supplying power to the solid material grinding unit 60 for a predetermined time, if the solid material grinding signal is still generated in the comparison circuit unit A40, the failure is generated. By judging, the operation of stopping the operation of the solid grinding unit 60 and generating a failure signal. When the fault generation processing circuit unit A70 continues to delay the timer T3 for a predetermined time and then receives the solid grinding signal from the comparator unit, it sends a low signal to the AND gate AD1 to stop the power supply and the transistor. By operating TR12, the relay RY2 operates to activate an alarm means (e.g., an alarm) to notify the driver of the failure.
