Description

Technical Field

[0001] This invention relates to the field of aluminum ingot production technology, and in particular to an aluminum liquid filtration and separation device for aluminum ingot production. Background Technology

[0002] In the aluminum ingot production process, molten aluminum often contains various impurities, including solid particles and trace element impurities. The presence of these impurities can seriously affect the purity and mechanical properties of aluminum ingots, reducing the quality of the final product. Existing aluminum molten aluminum filtration devices generally suffer from problems such as a single filtration stage and incomplete impurity removal. Furthermore, during the filtration process, molten aluminum is prone to solidification due to temperature drops, clogging the filter structure. Simultaneously, the reaction efficiency between molten aluminum and refining flux is low, failing to quickly remove trace element impurities. In addition, some devices lack sufficient installation stability of the filter components, which are prone to displacement during filtration due to the impact of molten aluminum or centrifugal force, leading to increased filter gaps, affecting filtration efficiency, and hindering improvements in production efficiency and product quality.

A refining cylinder is located below the centrifuge cylinder. The bottom of the refining cylinder has a discharge pipe with a ceramic valve. Multiple spiral conduits are embedded in the inner wall of the refining cylinder.

[0013] This invention also provides a method for filtering and separating molten aluminum in aluminum ingot production, comprising the following steps:

[0014] Assembly and preheating of the device: Insert the retaining ring into the annular groove of the centrifuge tube, tighten the top cover, and achieve a stable installation of the dual filtration mechanism through the pressure assembly; start the heater and preheat the filter plate to 650-680℃ through the heat-conducting ring and heat-conducting rod.

[0015] Feeding and coarse filtration: The molten aluminum is introduced through the feeding tank, the coarse filter plate intercepts large particles of impurities, and the drive component drives the scraper to clean the impurities, thus avoiding clogging of the filter holes.

[0016] Stirring and centrifugation with dual filtration: The stirring motor drives the stirring plate to rotate, causing the aluminum liquid to flow centrifugally. Fine impurities are intercepted step by step by the first and second annular filter plates under the action of centrifugal force.

[0017] Flux refining: Molten aluminum is tangentially introduced into the refining cylinder through a spiral conduit, forming a rotating flow; flux is evenly sprayed through the drain hole of the distributor pipe, reacting fully with the molten aluminum to remove trace element impurities.

This triple purification ensures the purity of the aluminum liquid and improves the mechanical properties of the aluminum ingot.

[0021] Anti-clogging and heat preservation design: The heat-conducting components preheat the annular filter plate to prevent the aluminum liquid from solidifying and clogging the filter holes; the scraper of the feeding mechanism can clean the impurities of the coarse filter plate in time to ensure that the filtration channel is unobstructed; the spiral conduit is embedded in the side wall of the refining cylinder to keep the aluminum liquid warm and maintain its fluidity.

Detailed Implementation

[0033] First Embodiment

[0034] Please see Figures 1-6 ,in, Figure 1This is a schematic diagram of the aluminum liquid filtration and separation device for aluminum ingot production according to the present invention. Figure 2 yes Figure 1 Enlarged view of point A in the middle. Figure 3 This is a cross-sectional view of the aluminum liquid filtration and separation device for aluminum ingot production according to the present invention. Figure 4 This is a schematic diagram of the internal structure of the centrifuge cylinder and refining cylinder of the present invention. Figure 5 This is a schematic diagram of the dual filtration mechanism of the present invention. Figure 6 This is a schematic diagram of the conveying pipe and the diversion pipe of the present invention.

[0035] This invention provides an aluminum liquid filtration and separation device for aluminum ingot production, comprising a centrifuge cylinder 101 with an arc-shaped protrusion at the bottom, a top cover 102 above the centrifuge cylinder 101, a stirring assembly and a feeding mechanism on the top cover 102, a dual filtration mechanism inside the centrifuge cylinder 101, and a flux refining mechanism below the centrifuge cylinder 101; an annular groove is provided on the bottom inner side of the centrifuge cylinder 101, the dual filtration mechanism includes a fixing ring 116 locked in the annular groove, a first annular filter plate 117 and a second annular filter plate 118 are provided on the upper end of the fixing ring 116, the first annular filter plate 117 is located inside the second annular filter plate 118, and a plurality of support columns 123 are uniformly and vertically arranged in the interlayer between the two, an mounting ring 119 is provided above the plurality of support columns 123, a heat conduction assembly is provided inside the mounting ring 119 and the plurality of support columns 123, and a plurality of pressure components are uniformly arranged on the mounting ring 119.

[0036] In this embodiment, the top cover 102 and the centrifuge cylinder 101 are connected by threads, which ensures the sealing performance of the device and facilitates disassembly and maintenance. When installing the dual filtration mechanism, first insert the fixing ring 116 into the annular groove at the bottom of the centrifuge cylinder 101, and then tighten the top cover 102. The inner wall of the top cover 102 will squeeze the pulley 133 of the pressure component, causing the mounting plate to move downward, causing the pressure spring 132 to contract and generate a continuous elastic force. This force is transmitted to the mounting ring 119 through the telescopic rod 134, which in turn pushes the fixing ring 116 to fit tightly against the inner wall of the annular groove, thus achieving a stable fixation of the dual filtration mechanism. This effectively avoids the filter plate from shifting due to the impact of molten aluminum or centrifugal force during filtration, ensuring uniform filtration gaps and improving filtration efficiency. The mounting ring 119 is placed over multiple support columns 123, the first annular filter plate 117, and the second annular filter plate 118. Multiple pressure components firmly press the mounting ring onto these components. When the dual filtration mechanism needs to be disassembled, the top cover 102 is opened, and the mounting ring 119 is pulled upwards to raise it. At the same time, multiple heat-conducting rods 122 are pulled out from the multiple support columns 123.

[0037] Furthermore, the heat-conducting assembly includes a heater 120 disposed at one end of the mounting ring 119. The top of the heater 120 is provided with a circular tube 135 for connecting the circuit. The top cover 102 is provided with a mounting port communicating with the circular tube 135 at a corresponding position. The output end of the heater 120 is provided with a heat-conducting ring 121 embedded in the mounting ring 119. A plurality of heat-conducting rods 122 are evenly disposed below the heat-conducting ring 121, and the heat-conducting rods 122 extend into the interior of the support column 123.

[0038] In this embodiment, the heat-conducting ring 121 is made of copper alloy with high thermal conductivity. The heat-conducting rod 122 is integrally formed with the heat-conducting ring 121 and is in close contact with the support column 123, the first annular filter plate 117, and the second annular filter plate 118. During operation, the heat generated after the heater 120 is started is quickly transferred to each heat-conducting rod 122 through the heat-conducting ring 121, and then conducted by the heat-conducting rod 122 to the first annular filter plate 117 and the second annular filter plate 118, preheating the filter plates to a range suitable for the temperature of the aluminum liquid (650-680℃), avoiding local solidification of the aluminum liquid due to low temperature filter plates, clogging the filter holes, and ensuring the fluidity of the aluminum liquid during the filtration process. After the top cover 102 is connected to the centrifuge cylinder 101 by threads, the round tube 135 is aligned with the mounting port to form a channel for installing electrical wires.

[0039] Furthermore, the stirring assembly includes a stirring motor 113 disposed above the top cover 102. The output end of the stirring motor 113 is provided with a stirring shaft 114 extending into the centrifuge cylinder 101. A stirring plate 115 is welded to the end of the stirring shaft 114. The bottom of the stirring plate 115 has the same curvature as the arc-shaped protrusion.

[0040] In this embodiment, the stirring plate 115 is completely in contact with the arc-shaped protrusion at the bottom of the centrifuge cylinder 101. After the stirring motor 113 is started, the stirring shaft 114 drives the stirring plate 115 to rotate at a speed of 30-40 r / min. This can not only fully stir the aluminum liquid and make the impurities in the aluminum liquid evenly distributed, but also drive the aluminum liquid to form a centrifugal flow. Under the action of centrifugal force, the impurities move to the outside, which is convenient for the dual filtration mechanism to intercept and improve the filtration efficiency.

[0041] Furthermore, the feeding mechanism includes a feeding trough 103 connected to the top cover 102, a coarse filter plate 104 is provided in the feeding trough 103, a driving component is provided at the top of the feeding trough 103, and a scraper 112 is provided at the output end of the driving component that contacts the upper surface of the coarse filter plate 104.

[0042] In this embodiment, the coarse filter plate 104 has a pore size of 1mm, which is used to intercept large particulate impurities (such as metal scraps, slag, etc.) with a diameter greater than 1mm in the molten aluminum. The scraper 112 is made of high-temperature resistant rubber and is in close contact with the upper surface of the coarse filter plate 104. It is driven by the drive assembly to move back and forth, which can scrape the impurities intercepted on the coarse filter plate 104 to the side of the feeding tank 103 in a timely manner, so as to avoid the accumulation of impurities and blockage of the filter holes, and ensure smooth flow of molten aluminum.

[0043] Furthermore, the drive assembly includes a drive motor 105 disposed at one end of the feeding trough 103. The output end of the drive motor 105 is provided with a drive shaft 106 extending into the feeding trough 103. One end of the feeding trough 103 is provided with a driven shaft 107 parallel to the drive shaft 106. The drive shaft 106 and the driven shaft 107 are driven by a transmission kit. Both the drive shaft 106 and the driven shaft 107 are provided with connecting brackets 111. The bottom of the two connecting brackets 111 is fixedly connected to the scraper 112.

[0044] In this embodiment, the drive motor 105 is a stepper motor, which can precisely control the speed. The drive shaft 106 and the driven shaft 107 drive the scraper 112 to move synchronously through the connecting bracket 111, ensuring that the scraper 112 moves smoothly and avoiding tilting or damage to the scraper 112 due to uneven force, thereby improving the stability and thoroughness of impurity removal.

[0045] Furthermore, the transmission assembly includes a drive wheel 108 disposed on the drive shaft 106, a driven wheel 109 disposed on the driven shaft 107, and a belt 110 for transmission is sleeved on the drive wheel 108 and the driven wheel 109.

[0046] In this embodiment, both the driving pulley 108 and the driven pulley 109 are synchronous pulleys, and the belt 110 is a high-temperature resistant synchronous belt to ensure that there is no slippage during transmission, thereby achieving synchronous rotation of the driving shaft 106 and the driven shaft 107, and thus ensuring the smooth reciprocating movement of the scraper 112 and improving the transmission reliability of the drive assembly.

[0047] Furthermore, a plurality of discharge ports 124 are evenly arranged around the bottom periphery of the centrifuge cylinder 101. The flux refining mechanism includes a spiral conduit 125 connected to the discharge port 124. A refining cylinder 131 is arranged below the centrifuge cylinder 101. A discharge pipe 129 with a ceramic valve 130 is arranged at the bottom of the refining cylinder 131. The plurality of spiral conduits 125 are embedded in the inner wall of the refining cylinder 131. The lower section of the spiral conduit 125 extends into the refining cylinder 131. The lower outlet of the spiral conduit 125 faces the horizontal side of the axis of the refining cylinder 131.

[0048] In this embodiment, the centrifuge cylinder 101 has 4-6 discharge ports 124 evenly arranged at its bottom. Each discharge port 124 is connected to a spiral conduit 125. The conduit is made of high-temperature resistant stainless steel and is embedded in the side wall of the refining cylinder 131. This design utilizes the heat-insulating environment of the refining cylinder 131 to keep the aluminum liquid inside the conduit warm and prevent temperature drop. The lower outlet of the conduit is arranged tangentially to the refining cylinder 131, so that the aluminum liquid flows in a vortex along the inner wall after entering the refining cylinder 131, increasing the contact area between the aluminum liquid and the flux.

[0049] Furthermore, a conveying pipe 126 extending into the refining cylinder 131 is provided at the top of the refining cylinder 131. Two diversion pipes 127 are uniformly connected to the conveying pipe 126. A plurality of drain holes 128 for discharging flux are uniformly provided below the diversion pipes 127.

[0050] In this embodiment, two diversion pipes 127 are symmetrically distributed inside the refining cylinder 131, and the orifices 128 have a diameter of 3-5 mm and are evenly distributed below the diversion pipes 127. The flux (such as magnesium chloride-sodium fluoride mixed flux) is transported to the diversion pipes 127 through the conveying pipe 126, and then evenly sprayed into the rotating aluminum liquid through multiple orifices 128, so that the flux and aluminum liquid are fully mixed and reacted, and the trace element impurities such as iron, silicon, and hydrogen in the aluminum liquid are efficiently removed.

[0051] Furthermore, the pressure assembly includes a telescopic rod 134 disposed above the mounting ring 119, a mounting plate disposed on the top of the telescopic rod 134, a pulley 133 disposed on the mounting plate that contacts the top cover 102, and a pressure spring 132 sleeved on the outside of the telescopic rod 134 disposed between the mounting ring 119 and the mounting plate.

[0052] In this embodiment, the pulley 133 is made of high-temperature resistant ceramic material, which can reduce friction between the top cover 102 and the mounting plate during tightening and avoid component wear. The telescopic rod 134 acts as a guide to ensure that the pressure spring 132 does not deviate during contraction and extension, so that the elastic force is transmitted vertically to the mounting ring 119, ensuring that the fixing ring 116 is evenly stressed and tightly fits the annular groove, thereby improving the installation stability of the dual filtration mechanism.

[0053] Working principle:

[0054] Assembly and preheating of the device: Insert the retaining ring 116 into the annular groove of the centrifuge cylinder 101, tighten the top cover 102, and achieve a stable installation of the dual filtration mechanism through the pressure assembly; start the heater 120, and preheat the first annular filter plate 117 and the second annular filter plate 118 to 650-680℃ through the heat-conducting ring 121 and the heat-conducting rod 122.

[0055] Feeding and coarse filtration: The aluminum liquid is introduced through the feeding tank 103, the coarse filter plate 104 intercepts large particles of impurities, and the drive component drives the scraper 112 to clean the impurities and avoid clogging of the filter holes.

[0056] Stirring and centrifugation with dual filtration: The stirring motor 113 drives the stirring plate 115 to rotate, causing the aluminum liquid to flow centrifugally. Fine impurities are intercepted step by step by the first annular filter plate 117 and the second annular filter plate 118 under the action of centrifugal force.

[0057] Flux refining: The molten aluminum is tangentially introduced into the refining cylinder 131 through the spiral conduit 125, forming a rotating flow; the flux is evenly sprayed through the drain hole 128 of the distributor 127, and reacts fully with the molten aluminum to remove trace element impurities.

[0058] Finished product discharge: After the reaction is completed, the ceramic valve 130 is opened, and the purified aluminum liquid is discharged through the discharge pipe 129 for subsequent aluminum ingot casting.
