Description

Technical Field

[0001] This utility model relates to a rapid separation device for the bottom copper of a copper smelting slag ladle, belonging to the technical field of copper smelting equipment. Background Technology

[0002] In the smelting process of copper smelting projects, the slag produced by the blowing furnace and refining furnace needs to be discharged into the slag bag for temporary storage and subsequent treatment. Since the slag contains a certain amount of copper, during the slag cooling process, the copper will settle to the bottom of the slag bag because its density is greater than that of the slag, forming "bottom copper".

[0003] In existing technologies, the copper at the bottom of the ladle must be cut and crushed using specialized cutting tools (such as flame cutting or mechanical cutting equipment) after the slag has completely cooled before it can be returned to the furnace for remelting. This method has two major problems: 1. High processing costs: The cutting process consumes a lot of energy (such as gas and electricity) and requires specialized operating equipment and personnel, resulting in high labor and equipment costs; 2. Long processing cycle: Before cutting, it is necessary to wait for the slag and bottom copper to cool completely (usually several hours to tens of hours). The cutting process itself also takes a long time, which seriously affects the efficiency of the bottom copper to be recycled, thereby reducing the capacity utilization rate of the entire smelting process.

[0004] Therefore, there is an urgent need for a device that can automatically separate the bottom copper and directly remelt it without additional cutting, in order to solve the pain points of high cost and long cycle in the existing technology. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a rapid separation device for bottom copper of copper smelting slag ladle. This device can effectively overcome the defects of high cost and long cycle of bottom copper disposal in the prior art, realize automatic deposition and separation of bottom copper, and can be directly returned to the furnace without cutting, thereby reducing costs and shortening the processing cycle.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a rapid separation device for copper bottom of copper smelting slag ladle, comprising a cross-shaped frame body, wherein the cross-shaped frame body comprises a longitudinal partition plate and a transverse partition plate, both of which are semi-circular plates; the longitudinal partition plate and the transverse partition plate are perpendicularly and fixedly connected, and the space between the longitudinal partition plate and the transverse partition plate is a partitioned chamber; the connection between the longitudinal partition plate and the transverse partition plate is a chamfered connection, and the longitudinal partition plate and the transverse partition plate are an integral structure.

[0007] The cross-shaped frame body fits into the bottom of the slag bag, and the outer contour of the cross-shaped frame body matches the inner wall contour of the bottom of the slag bag.

[0008] Furthermore, the arcuate portions of the longitudinal partition and the transverse partition are both on the same side, with the arcuate portions of the longitudinal partition and the transverse partition facing downwards, forming the bottom of the cross-shaped frame body.

[0009] Furthermore, the main body of the cross-shaped frame is made of high-temperature resistant metal material, which is 20# steel or a high-temperature resistant alloy with a melting point ≥1500℃.

[0010] Furthermore, the thickness of both the longitudinal and transverse partitions is 30mm to 60mm, and the height of both the longitudinal and transverse partitions is 500mm to 1000mm.

[0011] Furthermore, the bottom of the cross-shaped frame body is provided with a positioning groove, which is a positioning recess, and the inner wall of the bottom of the slag bag is provided with a positioning protrusion that matches the positioning groove.

[0012] Furthermore, the high-temperature resistant alloy is a Cr-Mo alloy or a nickel-based alloy.

[0013] The beneficial effects of this utility model are: 1) "Automatic separation of bottom copper": The bottom of the slag bag is divided into four deposition chambers by the cross-shaped frame body. After the bottom blow furnace slag is discharged into the slag bag, the bottom copper naturally settles into each chamber. After cooling, it forms independent small pieces of bottom copper, which can be directly removed when the bag is turned over without additional cutting, thus solving the problem of high cutting cost in the existing technology. 2) "Shortening the processing cycle": Eliminating the waiting and cooling time before cutting and the cutting operation time, the copper at the bottom of the ladle can be directly removed from the slag ladle with the ladle flipping action after cooling, improving the return efficiency by more than 60% and significantly shortening the material circulation cycle of the entire smelting process. 3) "High temperature resistance and strong stability": Made of 20# steel or high temperature resistant alloy, it can withstand the high temperature of slag of 1200-1400℃ for a long time, avoiding high temperature deformation or damage, and the service life can reach 1 to 2 years, reducing the frequency of equipment replacement. 4) “Strong adaptability”: The outer contour of the cross-shaped frame body is adapted to the inner wall of the bottom of the slag bag, and it is fixed by positioning protrusions and grooves. It can be adapted to the existing mainstream specifications of copper smelting slag bags without the need for large-scale modification of the slag bag, thus lowering the application threshold.

[0014] This device solves the problems of high cost and long cycle of existing slag bottom copper disposal, significantly improves recycling efficiency, is compatible with existing slag ladles, and has a low application threshold; it is suitable for automatic separation and rapid recycling of slag bottom copper after slag discharge from blowing furnaces and refining furnaces, reducing the cost of slag bottom copper disposal and shortening the cycle.

[0019] like Figure 1 As shown in Figure 2, a rapid separation device for the bottom copper of a copper smelting slag ladle includes a cross-shaped frame body, which further includes a longitudinal partition plate 1 and a transverse partition plate 2. Both the longitudinal partition plate 1 and the transverse partition plate 2 are semi-circular plates. The longitudinal partition plate 1 and the transverse partition plate 2 are vertically and intersectingly fixedly connected, and the space between the longitudinal partition plate 1 and the transverse partition plate 2 is a partition chamber 5. The connection between the longitudinal partition plate 1 and the transverse partition plate 2 is a chamfered corner 3, and the longitudinal partition plate 1 and the transverse partition plate 2 are an integral structure.

[0020] The cross-shaped frame body fits into the bottom of the slag bag, and the outer perimeter of the cross-shaped frame body matches the inner wall profile of the bottom of the slag bag; the bottom of the cross-shaped frame body is provided with a positioning groove, which is a positioning recess 4, and the inner wall of the bottom of the slag bag is provided with a positioning protrusion that matches the positioning groove.

[0021] The arc-shaped portions of the longitudinal partition 1 and the transverse partition 2 are on the same side, and the arc-shaped portions of the longitudinal partition 1 and the transverse partition 2 are arranged downwards, forming the bottom of the cross-shaped frame body.

[0022] The main body of the cross-shaped frame is made of high-temperature resistant metal material, which is 20# steel or a high-temperature resistant alloy with a melting point ≥1500℃. The high-temperature resistant alloy is Cr-Mo alloy or nickel-based alloy.

[0023] The thickness of both the longitudinal partition 1 and the transverse partition 2 is 30mm to 60mm, and the height of both the longitudinal partition 1 and the transverse partition 2 is 500mm to 1000mm.

[0024] During use, the cruciform frame is composed of vertically intersecting longitudinal partition plates 1 and transverse partition plates 2, which are fixed together. The partition chamber 5 formed between the longitudinal partition plates 1 and the transverse partition plates 2 divides the bottom space of the slag bag into four independent sedimentation chambers. The thickness of both the longitudinal partition plates 1 and the transverse partition plates 2 is 30mm to 60mm, ensuring the structural strength of the cruciform frame in high-temperature environments (slag temperature is usually 1200 to 1400℃) and preventing partition failure due to high-temperature deformation. The height of both the longitudinal partition plates 1 and the transverse partition plates 2 is 500mm to 1000mm, which is lower than the height of the slag bag sidewalls (the height of the slag bag is usually 1.5m to 3m), ensuring that the slag can be smoothly discharged into the slag bag while ensuring the stability of the bag. The bottom copper can be completely deposited in the deposition chamber, forming an independent block structure. The bottom of the cross-shaped frame body is provided with a positioning recess 4 as a "positioning groove". The inner wall of the center of the bottom of the slag bag is provided with a positioning protrusion that matches the positioning groove. Through the cooperation of the positioning protrusion and the positioning groove, the cross-shaped frame body is fixed at the bottom of the slag bag, preventing the cross-shaped frame body from shifting when the slag is discharged. After the bottom blown furnace slag is discharged into the slag bag, the copper naturally settles into each deposition chamber under the action of the longitudinal partition plate 1 and the transverse partition plate 2. After cooling, it forms an independent block of bottom copper. When the bag is turned over, the cross-shaped frame body and the bottom copper can be directly detached together. The bottom copper and the cross-shaped frame body will automatically separate during the fall and can be returned to the furnace without cutting.
