On the other hand, the discharge unit 116 of the cooling chamber 110 may be provided with a discharge variable unit 210 for controlling the discharge of the sintered ore.

Referring to FIG. 2, which is an enlarged cross-sectional view of the discharge unit of the sintered ore cooler according to an embodiment of the present invention, in the present embodiment, the discharge variable unit 210 is provided to vary the discharge in relation to the temperature of each discharge location of the sintered ore. Can be.

The discharge variable unit 210 may include a split hopper part 220 provided to the discharge part 116 of the cooling chamber 110 to split and discharge the sintered ore. For example, in the present exemplary embodiment, the discharge part 116 and the split hopper part 220 provided therein may be divided into four parts to partition each area.

In addition, each region of the discharge unit 116 or the split hopper unit 220 may be provided with a temperature measuring unit 230 for measuring the discharge temperature of the sintered ore.

In addition, the split hopper 220 may be provided with at least one vibration feeder (221) for varying the vibration in accordance with the discharge temperature of the sintered ore measured by the temperature measuring unit 230 and to control the discharge of the sintered ore. .

For example, as in the present embodiment, four divided feeders 220a, 220b, 220c, and 220d divided into four are provided with four vibration feeders 221 corresponding to each, and each of the vibration feeders 221. The operation can be controlled individually.

For example, the vibration feeder 221 may include a discharge plate 222 provided below the split hopper 220. In addition, the vibration feeder 221 may include a vibration generating unit 224 linked to vibrate the discharge plate 222. Here, the discharge plate 222 is provided rotatably by a rotation connecting member such as a hinge on one side, it can rotate in conjunction with the operation of the vibration generating unit 224 and generate vibration.

In the present embodiment, the vibration generator 224 may include at least one motor, and may transmit vibration to the discharge plate 222 as the motor operates in conjunction with the discharge plate 222. To this end, a connection member 226 may be provided between the discharge plate 222 and the vibration generating unit 224 to convert the rotational motion into a reciprocating motion or an eccentric rotational motion.

In addition, in the present embodiment, the vibration generating unit 224 may generate a vibration by combining in at least one direction of horizontal, vertical, oblique, or rotational directions.

In addition, the discharge plate 222 may be disposed to be inclined downward at a predetermined angle, for example, it is also possible to adjust the inclined angle of the discharge plate 222.

Preferably, the discharge temperature of the sintered ore measured by the temperature measuring unit 230 may be transmitted to the control unit 240. In addition, the control unit 240 may control the vibration amount of the discharge plate 222 in conjunction with the temperature of the sintered ore discharged by controlling the motor rotational speed of the vibration generating unit 224. To this end, in the present embodiment, the control unit 240 may vary the frequency according to the discharge temperature of the sintered ore. In addition, in the present embodiment, the motor of the vibration generating unit 224 may be applied to an inverter motor whose rotational speed is controlled according to the frequency.

That is, in the present embodiment, when the discharge temperature of the sintered ore is higher than the set temperature, the discharge variable unit 210 may reduce the vibration of the discharge plate 222 by lowering the motor rotation speed of the vibration generating unit 224. As such, when the vibration of the discharge plate 222 is reduced, the discharge of the sintered ore is reduced, the time for which the sintered ore stays in the cooling chamber 110 is increased and may be discharged after sufficient cooling is performed.

In addition, when the discharge temperature of the sintered ore is lower than the set temperature, the discharge variable unit 210 may increase the rotational speed of the motor of the vibration generating unit 224 to increase the vibration of the discharge plate 222. As such, when the vibration of the discharge plate 222 is increased, the discharge of the sintered ore is increased to quickly discharge the sintered ore having completed cooling.

For example, in the present embodiment, when the split hopper 220 is divided into a plurality, the temperature of the sintered ore discharged to each split hopper portion (for example, 220) is measured, and the other split hopper portion (eg, 220b) is measured. , At least one of 220c and 220d), reduce the vibration of the discharge plate 222 by reducing the vibration of the discharge plate 222 by slowing down the operating speed of the vibration generating unit 224 of the vibration feeder 221 having the higher discharge temperature of the sintered ore. Can be.

In addition, when the temperature of the sintered ore discharged to one of the split hopper parts (for example, 220a) is lower than the other of the split hopper parts (for example, at least one of 220b, 220c, and 220d), the lower side of the sintered ore discharge temperature is lower. By increasing the operating speed of the vibration generating unit 224 of the vibration feeder 221 to increase the vibration of the discharge plate 222 can increase the discharge rate.

In addition, the control unit 240 may vary the discharge relative to the temperature of the sintered ore discharged to each of the split hopper 220a, 220b, 220c, 220d, and to control the discharge to vary in response to the preset temperature It is also possible.

In addition, in the present embodiment, the vibration generating unit 224 is described as using the rotational force of the motor, it is possible to generate the vibration by moving the discharge plate 222 using an actuator using hydraulic or pneumatic, motor or actuator It is also possible to generate a vibration by combining a variety of exercise means such as.

On the other hand, in the present embodiment, the discharge variable unit 210 is described as controlling the discharge in response to the discharge temperature for each discharge position of the sintered ore, but is not limited thereto.

For example, in the present embodiment, the discharge variable unit 210 may control the discharge of the sintered ore corresponding to the discharge distribution of the sintered ore.

To this end, each area of the discharge unit 116 or the split hopper unit 220a, 220b, 220c, 220d may be provided with a proximity sensor in place of the temperature measuring unit.

The proximity sensor can measure the discharge distribution of the sintered ore discharged to the split hopper unit 220a, 220b, 220c, 220d, by using the control unit determines whether the sintered ore is segregated in the cooling chamber 110, etc. The operation of the 221 may be controlled to vary the discharge of the sintered ore discharged through each of the split hopper parts 220a, 220b, 220c, and 220d.

For example, when the sintered ore discharged to one of the split hopper parts (for example, 220a) is larger than the split hopper part of the other (for example, at least one of 220b, 220c, and 220d), the vibration of the sintered ore is more emitted. By reducing the operating speed of the vibration generating unit 224 of the feeder 221 can reduce the vibration of the discharge plate 222 to reduce the discharge.

In addition, when the sintered ore discharged to one of the split hopper parts (for example, 220a) is smaller than the other of the split hopper parts (for example, at least one of 220b, 220c, and 220d), the sintered ore discharge is smaller. By increasing the operating speed of the vibration generating unit 224 of 221 to increase the vibration of the discharge plate 222 can increase the discharge rate.

In addition, the sensing means for detecting the sintered light discharged to the split hopper unit 220a, 220b, 220c, 220d in this embodiment may be applied in addition to the proximity sensor. In one example, the sensing means may include a pressure sensor provided on each discharge plate 222, the sintered ore discharged to each of the split hopper portion 220a, 220b, 220c, 220d through the pressure measured by the pressure sensor It is also possible to determine the emission distribution of.

For example, the sintered ore may be supplied to the sintered ore cooler 100 by the movement of the sintered bogie 12.

At this time, the sintered trolley 12 has a predetermined unit length. Accordingly, after the sintered ore is supplied from the preceding sintered trolley 12, the sintered ore is supplied from the following sintered trolley (12 'shown in FIG. 1). Until a predetermined time until the input delay of the sintered ore may occur. In one example, the conventional sinterer 10 has a time difference of about 20 to 25 seconds between the preceding sintering bogie 12 and the following sintering bogie 12 '.

Accordingly, the sintered ore cooler 110 may be in a state in which the input unit 114 of the cooling chamber 110 is opened for a delay time in which the sintered ore is not introduced into the cooling chamber 110, and thus heat generated during cooling of the sintered ore Bar can be discharged, the present embodiment is to block the discharge of heat by providing a heat discharge blocking unit 310 to the input unit 114 of the sintered ore cooler 110.
