Description

Technical Field

[0001] The present invention relates to the technical field of non-ferrous metal smelting, and particularly relates to an aluminum casting and rolling liquid discharging device for preventing turbulence. Background Art

[0002] Aluminum is the third most abundant element in the earth's crust after oxygen and silicon, and is the most abundant metallic element in the earth's crust. The development of the three major important industries of aviation, construction, and automobiles requires the material properties to have the unique properties of aluminum and its alloys, which greatly facilitates the production and application of metallic aluminum. During the processing of aluminum blocks, the liquid discharging speed of the aluminum liquid will directly affect whether the aluminum liquid shows the phenomenon of backwater. If the casting speed is too fast, it will cause the aluminum liquid to form turbulence and bubbles. If the casting speed is too slow, the aluminum liquid will cool and solidify, forming backwater. Therefore, during the casting process, it is necessary to determine an appropriate casting speed according to the properties of the material, and thus an aluminum casting and rolling liquid discharging device is needed.

[0003] The flow channel groove of the traditional aluminum casting and rolling liquid discharging device has a fixed width. Therefore, when casting aluminum blocks of different sizes, it is necessary to increase the liquid discharging flow rate of the aluminum liquid to prevent the speed of the aluminum liquid injected into the equipment from being too slow and affecting the processing quality of the aluminum block. However, since the width of the flow channel groove remains unchanged, increasing the liquid discharging flow rate of the aluminum liquid is likely to cause the aluminum liquid to form turbulence, thereby generating bubbles and further affecting the quality of the aluminum casting and rolling products. In view of the disadvantages of the traditional technology, those skilled in the art have proposed an aluminum casting and rolling liquid discharging device for preventing turbulence.

An installation groove is formed in the runner brick seat, and a rotating through groove is formed between the installation groove and the liquid discharge groove. A regulating rotating shaft is installed in the installation groove, and a regulating rotating baffle is fixedly installed on the part of the regulating rotating shaft located in the inner cavity of the rotating through groove. A number of liquid discharge orifice plates with different apertures are fixedly installed on the regulating rotating baffle. A first servo motor is fixedly installed on the top surface of the runner brick seat, and a driving rotating shaft is connected to the output end of the first servo motor. A driving gear is fixedly installed on the driving rotating shaft. A driven gear is fixedly installed on the regulating rotating shaft, and the driven gear meshes with the driving gear. On the other hand, fixing frames are symmetrically and fixedly installed on the side wall of the runner brick seat, and a bidirectional lead screw is installed on the fixing frames. One end of the bidirectional lead screw is connected to the output end of a second servo motor. A guiding slide bar is fixedly installed on the fixing frames. High-temperature resistant ceramic side plates are symmetrically arranged in the inner cavity of the runner groove. One end of the top of the high-temperature resistant ceramic side plates is fixedly connected with an adjusting connecting plate.

Guide sleeves are symmetrically and fixedly installed on the two adjusting connecting plates, and the guide slide bar is sleeved in the guide sleeves. When in use, when the user needs to use a larger aluminum casting and rolling equipment, the worker can start the second servo motor through the control panel to drive the bidirectional lead screw to rotate, so that the two adjusting connecting plates move relatively along the direction of the guiding slide bar, and then the distance between the two high-temperature resistant ceramic side plates can be adjusted to change the liquid surface width when the molten aluminum passes through the runner groove, making it more suitable for the larger equipment and improving the quality of aluminum casting and rolling. After adjusting the position of the high-temperature resistant ceramic side plates, the worker can drive the driving rotating shaft to rotate through the first servo motor, so that the regulating rotating shaft drives the regulating rotating baffle to rotate, making the liquid discharge orifice plate with a large aperture installed on the regulating rotating baffle align with the liquid outlet.

When the liquid level changes greatly and frequently when the aluminum liquid passes, workers need to check and regulate the flow rate of the aluminum liquid to troubleshoot the possible causes of turbulence in the aluminum liquid. A temperature gun shell is set to detect the temperature of the aluminum liquid entering the flow channel. When the temperature of the aluminum liquid drops too quickly, the control panel can start the electric heating rod to heat the aluminum liquid to keep the aluminum liquid at a suitable temperature for casting and rolling, to prevent the aluminum liquid from being too low in temperature and causing water backflow, which is beneficial to improving the quality of aluminum liquid discharge and the quality of processed products.

This control method is simple and convenient, and the switch control of the discharge tank is also more convenient. In addition, when it is necessary to clean the aluminum slag blocked in the holes of the discharge orifice plate, it is only necessary to rotate the discharge orifice plate to the top of the mounting groove. After the aluminum slag is cooled, the workers can use the equipment to clear and clean the aluminum slag remaining in the discharge orifice plate. The operation is simple and convenient, saving time and effort. There is no need to disassemble the discharge control mechanism. Compared with the traditional discharge control mechanism, the later maintenance is more convenient and more practical. BRIEF DESCRIPTION OF THE DRAWINGS

When the liquid level changes greatly and frequently when the molten aluminum passes through, the worker needs to check and regulate the flow velocity of the molten aluminum to find out the reasons that may cause the molten aluminum to generate turbulence. The temperature measuring gun 17 can detect the temperature of the molten aluminum entering the flow channel groove 1. When the temperature of the molten aluminum drops too fast, the control panel 14 can start the electric heating rod 2 to heat the molten aluminum so that the molten aluminum maintains an appropriate temperature for casting and rolling, preventing the molten aluminum from having backwater due to too low temperature, being beneficial to improving the discharging quality of the molten aluminum and the processing product quality.
