Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to an aluminum liquid stirring device. Background Art

[0002] Liquid aluminum is a kind of alloy liquid, usually composed of aluminum and other alloy elements. Liquid aluminum is widely used in the manufacture of various aluminum products, including casting, extrusion, deep drawing and rolling processes, and can produce aluminum products of various shapes, such as plates, pipes, profiles, castings, etc.; During the production process of liquid aluminum, liquid aluminum usually contains unevenly distributed impurities, which will affect the quality of the liquid aluminum. For example, during the aluminum smelting and casting process, a large amount of hydrogen, nitrogen and other gases will be produced in the liquid aluminum. These gases will cause defects such as pores and looseness in aluminum castings, seriously affecting the quality and performance of the castings. Some non-metallic inclusions mixed in the molten aluminum, such as oxide film, slag, etc., will reduce the mechanical properties and corrosion resistance of aluminum castings, and will also affect the quality of aluminum products and reduce the service life of the products.

[0003] The existing aluminum liquid stirring device can only control the upper and lower working positions of the stirring mechanism when in use, and cannot stir the aluminum liquid in the aluminum liquid tank at different positions in different use environments, thereby reducing the working efficiency and the quality of the aluminum liquid. In addition, the stirring blades of most stirring mechanisms are made of metal alloys. Since the aluminum liquid is in a high temperature environment during stirring, and long-term stirring work is required to maintain the fluidity of the aluminum liquid, the stirring blades made of metal alloys will inevitably react with the aluminum liquid to produce impurities when working in such an environment. In addition, long-term work will cause damage to the stirring blades made of metal alloys, thereby increasing the use and maintenance costs of the device.

[0004] In view of this, it is necessary for the applicant to design an aluminum liquid stirring device that can conveniently stir the aluminum liquid in different working environments and workstations, while also effectively eliminating impurities and gases in the aluminum liquid, thereby improving the quality of the aluminum liquid, reducing casting defects, improving product quality, reducing the use loss and cost of the device, and increasing the service life of the device.

[0027] like Figures 1 to 3As shown, the utility model proposes an aluminum liquid stirring device, including a machine base 1, a first support frame 2 is rotatably provided on the upper end of the machine base 1, a rocker arm 3 is slidably provided on the side of the first support frame 2, a hoisting mechanism 4 for hoisting the rocker arm 3 for sliding is fixedly provided on the upper end of the first support frame 2, a second support frame 5 is fixedly provided on the other end of the rocker arm 3, a transmission shaft 6 is rotatably provided inside the second support frame 5, a transmission drive mechanism 7 for driving the transmission shaft 6 to rotate is fixedly provided on the upper end of the second support frame 5, a rotating rod 8 is fixedly provided on the lower end of the transmission shaft 6, a box cover 9 for sealing the aluminum liquid box is sleeved on the upper end peripheral side surface of the rotating rod 8, and a stirring mechanism 10 is fixedly provided on the lower end of the rotating rod 8; when in use, the utility model The first support frame 2 is rotatably arranged on the machine base 1, so that the rocker arm 3 can not only slide in the axial direction of the first support frame 2 under the lifting action of the lifting mechanism 4, but also achieve the effect of rotational transformation, so as to meet the needs of different workstations in different working environments and improve work efficiency. A transmission drive mechanism 7 for driving the transmission shaft 6 is fixedly arranged at the upper end of the second support frame 5, and then a rotating rod 8 is fixedly arranged at the lower end of the transmission shaft 6. The box cover 9 sleeved on the upper end of the rotating rod 8 can seal the box containing the aluminum liquid to keep the temperature of the aluminum liquid from decreasing. A stirring mechanism 10 is fixedly arranged at the lower end of the rotating rod 8 to drive the stirring mechanism 10 to perform stirring work.

[0028] like Figure 1 As shown, a slide rail 11 is fixedly provided on one side between the two ends of the first support frame 2, a sliding frame 12 is slidably provided on the slide rail 11, the sliding frame 12 is fixedly connected to one end of the rocker arm 3, and a fastener 13 is fixedly provided on the other end of the sliding frame 12; when in use, the rocker arm 3 is fixedly connected to the sliding frame 12, and when the sliding frame 12 slides on the slide rail 11 of the first support frame 2, it can also drive the rocker arm 3 to slide, and when it slides to a suitable work position, it is positioned by the fastener 13.

[0029] like Figure 1 As shown, the hoisting mechanism 4 includes a first motor 14, a pulley 15, and a traction rope 16. The first motor 14 is fixedly connected to the upper end of the first support frame 2. The pulley 15 is rotatably installed on the oblique upper side of the upper end of the first support frame 2 through an oblique bracket 401. One end of the traction rope 16 is connected to the driving end of the first motor 14, and the other end is fixedly connected to the middle upper side of the rocker arm 3 after being wrapped around the pulley 15; when the height of the working position of the rocker arm 3 needs to be adjusted, the first motor 14 is started and drives the pulley 15 on the oblique bracket 401 to rotate through the traction rope 16. At this time, the traction rope 16 wrapped around the pulley 15 produces a rope-collecting or rope-releasing effect according to the forward or reverse rotation of the first motor 14, thereby achieving the effect of controlling the raising or lowering of the working position of the rocker arm 3.

[0030] like Figure 1As shown, the transmission drive mechanism 7 includes a support plate 17, a second motor 18, and a transmission belt 19. One end of the support plate 17 is fixedly connected to the upper end of the second support frame 5, and the second motor 18 is fixedly connected to the other end of the support plate 17.

[0031] like Figure 1 As shown, ventilation holes 20 are provided in the axial direction of the transmission shaft 6 and the rotating rod 8; since a large amount of hydrogen and oxidized inclusions are contained in the aluminum liquid during purification and impurity removal, the hydrogen in the aluminum liquid will be absorbed into the bubbles of the inert gas after the inert gas is blown into the aluminum liquid. After the bubbles float out of the liquid surface, the hydrogen in the bubbles escapes into the atmosphere, and in the process of the bubbles floating, they will meet the oxidized inclusions, and the inclusions will be adsorbed on the surface of the bubbles and float to the surface of the liquid with the bubbles.

[0032] like Figure 2 As shown, the stirring mechanism 10 includes a stirring shaft 21 and stirring blades 22. The upper end of the stirring shaft 21 is clamped at the lower end of the rotating rod 8. A plurality of groups of stirring blades 22 distributed in a circumference are fixedly arranged on the peripheral side of the stirring shaft 21. When stirring, the stirring shaft 21 is driven by the rotating rod 8 to rotate, so as to drive the stirring blades 22 to stir and form a vortex in the aluminum liquid, so that impurities and bubbles in the aluminum liquid are fully dispersed, broken and removed, and finally the aluminum liquid is evenly mixed. The stirring shaft 21 preferably has an outer diameter of The stirring shaft 21 is a hollow cylinder with a diameter of 95mm and an inner diameter of 65mm. Several groups of stirring blades 22 distributed in a circumference are fixedly arranged on the peripheral side of the stirring shaft 21, preferably 8 groups, and the group spacing of each group is 100mm, and each group of stirring blades 22 is 8 cylinders with a diameter of 10mm and a length of 22.5mm, which are evenly distributed around the stirring shaft 21. By using multiple groups of stirring blades 22, the aluminum liquid is stirred more evenly, and the aluminum liquid layers at different depths are stirred at the same time, which can also improve the stirring efficiency of the aluminum liquid.

[0033] like Figure 3 As shown, the stirring blade 22 is a cylindrical structure, and the stirring blade 22 is made of quartz. When stirring, since the aluminum liquid is in a high temperature state, the cylindrical stirring blade 22 has a small contact area with the solution during stirring, so the resistance during stirring will also be reduced, making the stirring process smoother and the stirring of the aluminum liquid more sufficient. At the same time, it will also prevent the high-temperature aluminum liquid from splashing and causing safety accidents. The material of the stirring blade 22 is quartz, which has the characteristics of high hardness, high melting point and high corrosion resistance. Therefore, it is more stable when working in high-temperature aluminum liquid for a long time, thereby increasing the service life of the stirring device and reducing the use cost.

[0034] The working principle of the aluminum liquid stirring device based on the embodiment is as follows: when the utility model is in use, the working position of the rocker arm 3 is lifted and lowered by the forward and reverse rotation of the first motor 14 in the hoisting mechanism 4 through the traction rope 16, and the first support frame 2 is rotatably set on the machine base 1, so that the first support frame 2 drives the rocker arm 3 to rotate in the horizontal direction through the sliding frame 12, so as to meet the needs of different positions in different working environments and improve work efficiency. The transmission shaft 6 is driven to rotate by the second motor 18, and the transmission shaft 6 drives the stirring shaft 21 to rotate through the rotating rod 8 to perform stirring work, and the shaft between the transmission shaft 6 and the rotating rod 8 is A vent hole 20 is provided in the linear direction. When stirring, inert gas can be blown into the aluminum liquid, so that the bubbles generated by the inert gas absorb the hydrogen in the aluminum liquid and oxidize the inclusions, so as to achieve the effect of purifying the aluminum liquid. By selecting the stirring blades 22 as multiple groups of cylindrical shapes distributed in a circle and made of quartz material, the stirring device can perform stirring work in high-temperature aluminum liquid for a long time, and multiple groups of stirring blades 22 can stir aluminum liquid of different depths at the same time, so that the mixing of the aluminum liquid is more uniform, so that the impurities and bubbles in the aluminum liquid are fully dispersed, broken and removed, thereby improving the stirring efficiency of the aluminum liquid and extending the service life of the device.

[0035] The above-mentioned specific embodiments are only several preferred embodiments of the present invention.
