Description

Technical Field

[0001] This utility model relates to the field of industrial metallurgical technology, and more specifically, to a flow channel device used in the copper molten casting process in a converter. Background Technology

[0002] Copper is a common smelting metal in industrial metallurgy. When it is used in a converter, a trough device is needed to transfer the smelted copper liquid through the converter. Electrolytic copper or other high-purity copper materials are generally selected as the main materials for making copper troughs because copper has good corrosion resistance, thermal conductivity and ductility, can withstand the scouring and corrosion of high-temperature copper liquid or matte, and can quickly transfer heat to the cooling medium.

[0003] Harmful gases are generated when copper passes through the trough device during the copper smelting and casting process in the converter. Currently, the method used is to add a waste gas collection device to collect and treat these gases. However, this collection method becomes saturated with operating time, eventually ceasing waste gas collection. Furthermore, the collected waste gas is directly discharged and cannot be reused, making it difficult to integrate with the cooling structure of the trough device, thus limiting its application. Therefore, we propose a trough device for use in the copper smelting and casting process in a copper molten metal converter. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a trough device for the copper molten casting process in a converter, so as to solve the technical problem that the current trough plate exhaust gas collection is not convenient to use in conjunction with the cooling structure.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flow channel device for copper molten casting in a converter process, comprising a flow channel plate and a mixing structure. The mixing structure is located on the flow channel plate and includes a front-end inlet tank and a rear-end outlet tank. A gas transfer pipe and several water transfer pipes are installed between the inlet tank and the outlet tank. A pump body for drainage is installed inside the outlet tank. An extension pipe is installed on the outer wall of the pump body. Several water plates are evenly connected through the extension pipe at the input end of the pump body. A triangular plate is installed at the output end of the gas transfer pipe and the water transfer pipe inside the outlet tank. The water plates are located inside the triangular plate. A filter structure is connected to the gas input end of the inlet tank. A top plate is connected to the bottom of the filter structure. The top plate is installed on the top of the flow channel plate.

[0006] Preferably, a circulating water tray for circulating cooling is installed inside the flow channel plate. The two ends of the circulating water tray are respectively connected to an inlet pipe and a drain pipe. The circulating water tray is connected to the liquid inlet tank through the inlet pipe and to the output end of the pump body through the drain pipe.

[0007] Preferably, the filter structure includes a positioning tube penetrating the top plate, the positioning tube having an air hole for communicating with the flow channel plate, the positioning tube being filled with filter liquid and a flexible tube located in the filter liquid connected to the air hole, a sealing plate being installed on the positioning tube, a filter tube for gas filtration being installed at the bottom of the sealing plate, and an air inlet pipe for connecting to the liquid inlet tank being connected to the outer wall of the sealing plate.

[0008] Preferably, the liquid level in the inlet tank is higher than that in the water transfer pipe and lower than that in the gas transfer pipe. The inlet tank and the outlet tank have the same outer diameter. The water transfer pipe connecting the inlet tank and the outlet tank is installed horizontally.

[0009] Preferably, the triangular plate is in the shape of an arc triangle, and several water plates are evenly installed on the middle extension of the triangular plate at the pump body output end. Several slots are evenly opened on the water plates to increase the gas-liquid contact area. A bracket is installed at the bottom of the mixing structure, and the bottom of the bracket is connected to the top plate.

[0010] Preferably, the circulating water tray is installed inside the flow channel plate, and the circulating water tray and the flow channel plate are parallel to each other. Specifically, the circulating water tray is an arc-shaped channel structure opened on the flow channel plate, and the two ends of the arc-shaped channel are respectively connected to the water inlet pipe and the water outlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of a hybrid structure, achieves the simultaneous multiple circulation and filtration of harmful gases generated by liquid copper on the flow channel plate by mixing with coolant, while also achieving relative cooling of the liquid copper on the flow channel plate. During operation, the gas enters through the inlet tank and briefly resides there. Then, the pump creates negative pressure in the outlet tank, causing the gas and coolant in the inlet tank to be output through gas transfer pipe and water transfer pipe, respectively, to a triangular plate located in the outlet tank. The pump rotates, driving the water plate to rotate, stirring the gas and liquid within the triangular plate. The mixture is then output to the drain pipe by the pump's own characteristics, allowing the gas-liquid mixture to flow into the circulating water pan to cool the flow channel plate. Finally, it is output back to the inlet tank through the water inlet pipe for circulation. This solves the technical problem that the current flow channel plate exhaust gas collection is not convenient for use with a cooling structure.

[0012] 2. This utility model also achieves primary filtration of gas through the design of a filtration structure. The filtration structure includes a positioning tube and a connecting sealing plate and filter tube structure. During operation, filter liquid is injected into the positioning tube, and the filter liquid is prevented from flowing back through the external hose connected to the air hole. The filter tube is then installed on the liquid inside the positioning tube, and the filter tube is fixed and relatively sealed by the sealing plate. When the pump is working, relative pressure is generated inside the positioning tube. The gas is filtered by the filter liquid, then passes through the filter tube, and is output to the liquid inlet tank through the air inlet pipe, thus achieving the purpose of primary filtration and reducing impurities in the gas that directly enters the liquid inlet tank. After multiple gas-liquid mixing processes, the gas filtration is achieved, and the cooling operation is also convenient. Attached Figure Description

Detailed Implementation

[0015] like Figures 1 to 5As shown, this utility model relates to a trough device for use in a copper molten metal converter process, comprising a trough plate 100 and a mixing structure 200. The mixing structure 200 is located on the trough plate 100 and includes a front inlet tank 220 and a rear outlet tank 230. A gas transfer pipe 240 and several water transfer pipes 250 are installed between the inlet tank 220 and the outlet tank 230. A pump body 231 for drainage is installed inside the outlet tank 230. An extension pipe 232 is installed on the outer wall of the pump body 231. Several water plates 234 are evenly connected through the extension pipe 232. The output ends of the gas transfer pipe 240 and the water transfer pipe 250 are located inside the drain tank 230 and a triangular plate 233 is installed. The water plates 234 are located inside the triangular plate 233. The gas input end of the inlet tank 220 is connected to a filter structure 400. The bottom of the filter structure 400 is connected to a top plate 110. The top plate 110 is installed on the top of the flow channel plate 100.

[0016] This invention utilizes a hybrid structure 200 to achieve multiple cycles of filtration and relative cooling of the liquid copper on the flow channel plate 100 by mixing it with coolant. During operation, the gas enters through the inlet tank 220, briefly resides there, and then, pump 231 creates negative pressure in the outlet tank 230. This pressure causes the gas and coolant in the inlet tank 220 to flow through the gas transfer pipe 240. The gas and liquid mixture is discharged from the water transfer pipe 250 into the triangular plate 233 located in the drain tank 230. The pump body 231 rotates, driving the water plate 234 to rotate. After stirring the gas and liquid in the triangular plate 233, the gas and liquid mixture is discharged into the drain pipe 300 through the pump body 231 itself. This allows the gas-liquid mixture to flow into the circulating water pan 330 to cool the flow channel plate 100. Then, it is discharged into the liquid inlet tank 220 through the water inlet pipe 310 for circulation. This solves the technical problem that the current flow channel plate 100 is not convenient to use in conjunction with the cooling structure for waste gas collection.

[0017] This utility model also achieves primary filtration of gas through the design of a filter structure 400. The filter structure 400 includes a positioning tube 410 and a connected sealing plate 420 and filter tube 430. During operation, filter liquid is injected into the positioning tube 410, and a flexible hose connected to the air vent ensures that the filter liquid does not flow back. The filter tube 430 is then installed on the liquid inside the positioning tube 410, and the sealing plate 420 fixes and relatively seals the filter tube 430. When the pump body 231 is working, relative pressure is generated inside the positioning tube 410. The gas is filtered by the filter liquid, then passes through the filter tube 430, and finally exits through the air inlet pipe 320 into the liquid inlet tank 220, achieving the purpose of primary filtration and reducing impurities in the gas directly entering the liquid inlet tank 220. After multiple gas-liquid mixing processes, the gas filtration is achieved, while also facilitating cooling operations.

[0018] Specifically, a circulating water tray 330 for circulating cooling is installed inside the flow channel plate 100. The two ends of the circulating water tray 330 are connected to an inlet pipe 310 and a drain pipe 300, respectively. The circulating water tray 330 is connected to the liquid inlet tank 220 through the inlet pipe 310 and to the output end of the pump body 231 through the drain pipe 300. The circulating water tray 330 achieves the purpose of cooling the outside of the flow channel plate 100, realizing the secondary utilization of the collected waste gas and reducing the pollution caused by direct discharge. The operation mode of connecting the inlet pipe 310 and the drain pipe 300 facilitates large-scale cooling circulation operation on the flow channel plate 100, reduces equipment drive, and facilitates autonomous cooling circulation.

[0019] Furthermore, the filter structure 400 includes a positioning tube 410 penetrating the top plate 110. The positioning tube 410 has an air hole for communicating with the flow channel plate 100. The positioning tube 410 is filled with filter liquid, and a flexible tube located in the filter liquid is connected to the air hole. A sealing plate 420 is installed on the positioning tube 410. A filter tube 430 for gas filtration is installed at the bottom of the sealing plate 420. An air inlet pipe 320 for connecting to the liquid inlet tank 220 is connected to the outer wall of the sealing plate 420. The filter structure 400 realizes the initial filtration of exhaust gas. The flexible tube connected to the air hole is connected to the positioning tube 410 filled with filter liquid, and the filter tube 430 is inserted into the positioning tube 410. This allows the exhaust gas to be filtered by the liquid and then filtered by the filter tube 430, which improves the filtration effect and facilitates the subsequent replacement of the filter tube 430.

[0020] It is worth noting that the liquid level in the inlet tank 220 is higher than that in the water transfer pipe 250 but lower than that in the gas transfer pipe 240. The outer diameter of the inlet tank 220 and the outlet tank 230 are the same. The water transfer pipe 250 connecting the inlet tank 220 and the outlet tank 230 is installed horizontally. The constant liquid level in the inlet tank 220 prevents liquid from being output through the gas transfer pipe 240, reduces liquid retention in the gas transfer pipe 240, and ensures that the liquid directly contacts and mixes with the water plate 234 after passing through the bottom water transfer pipe 250, thereby improving the mixing performance.

[0021] It is worth mentioning that the triangular plate 233 has an overall arc-triangular structure. Several water plates 234 are evenly installed on the middle extension of the triangular plate 233 at the output end of the pump body 231. Several slots are evenly opened on the water plates 234 to increase the gas-liquid contact area. A bracket 210 is installed at the bottom of the mixing structure 200, and the bottom of the bracket 210 is connected to the top plate 110. The arc-triangular structure increases the probability of collision between the gas-liquid mixture and the triangular plate 233 when the water plates 234 rotate, and increases the collision frequency, thereby increasing the frequency of gas-liquid mixing. This facilitates subsequent output and improves the filtration performance of the gas, reducing impurities in the gas-liquid mixture entering the circulating water pan 330.

[0022] It is worth noting that the circulating water tray 330 is installed inside the flow channel plate 100. The circulating water tray 330 and the flow channel plate 100 are parallel to each other. Specifically, the circulating water tray 330 is an arc-shaped channel structure opened on the flow channel plate 100, and the two ends of the arc-shaped channel are respectively connected to the water inlet pipe 310 and the drain pipe 300. The circulating water tray 330 and the flow channel plate 100 adopt an integral molding structure, which improves the integrity of the circulating water tray 330 and facilitates the later connection and fixation with the water inlet pipe 310 and the drain pipe 300.

[0023] Working Principle: This embodiment provides a flow channel device for use in the copper molten casting converter process. During use, filtered liquid is injected into the positioning tube 410. An external hose connected to the vent ensures the filtered liquid does not flow back. The filter tube 430 is then installed on the liquid inside the positioning tube 410. The filter tube 430 is fixed and relatively sealed by the sealing plate 420. When the pump body 231 is working, relative pressure is generated inside the positioning tube 410. Gas passes through the filtered liquid, then through the filter tube 430, and finally through the air inlet pipe 320 to be output to the liquid inlet tank 220. The gas enters the liquid inlet tank 220 and then... After a brief pause, the pump body 231 generates negative pressure in the drain tank 230, causing the gas and coolant in the inlet tank 220 to be output through the gas transfer pipe 240 and the water transfer pipe 250 respectively to the triangular plate 233 located in the drain tank 230. The pump body 231 rotates, driving the water plate 234 to rotate, stirring the gas and liquid in the triangular plate 233. Then, the gas and liquid mixture is output to the drain pipe 300 through the pump body 231's own characteristics, so that the gas-liquid mixture flows into the circulating water pan 330 to cool the flow channel plate 100, and then is output to the inlet tank 220 through the water inlet pipe 310 for circulation.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
