Description

Slow cooling device for high-temperature melt

Technical Field

The utility model belongs to the technical field of metallurgy, and particularly relates to a slow cooling device for a high-temperature melt.

Background

While the smelting technology in China is rapidly developed, mineral raw materials are gradually deficient, and in order to improve the comprehensive utilization rate of resources, the process of carrying out slow cooling on smelting slag and then carrying out ore dressing to recover valuable metals gradually becomes a mainstream process for treating copper smelting slag. When slag is slowly cooled, the cooling speed of the slag is adjusted, so that crystallization can be promoted to be separated out to obtain larger crystals, and the subsequent ore dressing is facilitated.

Chinese patent CN106319113A discloses a slag ladle cooling device, which is provided with an infrared temperature measuring device on the top of the slag ladle through a support frame. Because there may be the difference in temperature in cinder ladle top and bottom, and in the water-cooling process, the cinder upper strata is full of cooling water in the cinder ladle, and the temperature data that infrared temperature measuring device surveyed from the cinder ladle top can't be used for judging the slag slow cooling condition.

Chinese patent CN212112204U discloses an automatic monitoring system of high-efficient slag yard, including the portal frame, the department that is close to slag ladle cooling position on the portal frame second side sets up infrared thermometer, and infrared thermometer is just setting up the lateral wall of sediment inclusion. Therefore, if the temperature of the slag ladle positioned at the second side edge far away from the portal frame needs to be measured, the slag ladle can be measured only by lifting the slag ladle to the temperature measuring position. The frequent hoisting of the high-temperature slag ladle has high operation difficulty and high danger coefficient, and the temperature of a single slag ladle can be measured in sequence only under the condition that the portal frame is stopped, so that the temperature measurement efficiency is low.

Chinese patent CN212505020U discloses an intelligent slow cooling device for high-temperature melt, which comprises a cooling field, a cooling area, a ladle turning area, a slag ladle stacking point, a crane rail, a slag ladle transportation point, an automatic temperature measuring device, an automatic spraying device, a water pumping point, a water pumping device and a controller; an automatic temperature measuring device is arranged beside the cooling field; automatic spraying devices are arranged on two sides of the cooling area; the controller is connected with the automatic temperature measuring device, the automatic spraying device and the crane. The automatic temperature measuring device is provided with the infrared camera, and based on the technical characteristics, a person skilled in the art cannot know how to set the automatic temperature measuring device to detect different slag ladle temperatures in the cooling area.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

A high-temperature melt slow cooling device is characterized in that a slag ladle stacking area 20 is arranged beside a rail 11 of a portal crane 10, a temperature measuring probe 30 is arranged on a vertical column 12 of the portal crane 10, and the temperature measuring probe 30 obliquely points downwards to the side wall of a slag ladle A in the slag ladle stacking area 20. Therefore, the temperature information of the side wall of the slag ladle A can be effectively acquired under the condition that the distance between the slag ladle A and the supporting leg 12 is small, and the temperature measuring probe 30 is positioned above the slag ladle A, so that the phenomenon that the temperature measuring effect is influenced because the sprayed or overflowing cooling water splashes and is attached to the temperature measuring probe 30 can be avoided.

As shown in the attached drawings 1-3, a spraying device is arranged beside the slag ladle A and comprises a spraying port 41 positioned above the slag ladle A and a spraying pipe column 42 standing beside the slag ladle A. The cooling water flows to the upper opening of the slag ladle A from the spray nozzle 41, and overflows along the side wall of the slag ladle A to fully cool the slag ladle A.

In order to ensure that the temperature measuring probe 30 can fully acquire the temperature information of the side wall of the slag ladle A and ensure the reliability of the measured temperature. The lowest part of the detection range of the temperature measuring probe 30 is not higher than the 1/4 height of the slag ladle A, namely, the side wall of the slag ladle A above the bottom 1/4 height is positioned in the detection range of the temperature measuring probe 30. The core shaft of the temperature measuring probe 30 and the plumb bob face are arranged at an included angle, so that the temperature measuring probe 30 is slightly deviated to the front or the rear, and when the spraying pipe column 42 is positioned between the slag ladle A and the portal crane track 11, the spraying pipe column 42 can be avoided to measure the temperature of the slag ladle A.

As shown in fig. 1-4, the slag ladles a in the slag ladle stacking area 20 are arranged along the extending direction of the rail 11 to form a slag ladle column, i.e. the extending direction of the slag ladle column is parallel to the extending direction of the rail 11, and only a single slag ladle column can be detected and measured by one temperature measuring probe 30. The side of the slag ladle A is provided with a spraying device which comprises a spraying port 41 positioned above the slag ladle A and a spraying pipe column 42 standing beside the slag ladle A. The cooling water flows to the upper opening of the slag ladle A from the spray nozzle 41, and overflows along the side wall of the slag ladle A to fully cool the slag ladle A.

In the embodiment shown in fig. 2, two slag ladle rows are arranged in the slag ladle stacking area 20 positioned on the inner side of the two rails 11 of the portal crane, and the spraying pipe column 42 is positioned between the two slag ladle rows, so that the spraying pipe column 42 can be prevented from shielding the slag ladle A to influence the temperature measurement result.

For the transportation of the slag ladle, the end part of the inner side of the portal crane track 11 is provided with a slag ladle transportation platform 51, and the slag ladle transportation platform 51 is connected with a slag dumping platform 53 beside the furnace body through a transportation track 52. The supporting legs 12 are provided with temperature measuring probes 30 for measuring the temperature of the slag ladle on the slag ladle transferring platform 51.
