Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy component casting, in particular to an automatic slag removal device for aluminum liquid. Background Art

[0002] During the casting process of aluminum alloy products, the aluminum ingot needs to be melted first. The surface of the aluminum liquid formed after melting usually has impurities such as aluminum slag floating on it. Before entering the next process, the aluminum slag impurities need to be cleaned up to avoid affecting the casting quality of the product. At present, the removal of aluminum slag and other impurities on site is mostly done manually. The operator holds a special colander and repeatedly removes the slag in the ladle. The manual labor intensity is high, the cleaning effect is poor, and multiple cleanings are required, which is inefficient. In addition, the dust generated during the slag removal process can easily cause occupational diseases to the operators and endanger their occupational health.

[0003] Based on this, it is an urgent problem to develop an automatic slag removal device for molten aluminum and apply it to actual production to reduce the labor intensity of operators, improve the slag removal efficiency, and enhance the cleaning effect of molten aluminum. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic slag removal device for molten aluminum in view of the above problems, so as to solve the problems of high labor intensity, poor cleaning effect and low efficiency in the existing slag removal operation of molten aluminum, and at the same time solve the problem of occupational disease hazard risk in the existing slag removal operation.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An automatic slag removal device for aluminum liquid comprises a filter plate arranged corresponding to the diameter of a casting ladle, the filter plate is conical, filter holes are opened on the filter plate, and the filter plate is escalably connected to a frame through a lifting mechanism.

[0007] Preferably, the frame includes a vertically arranged column, the top end of the column is connected to a crossbeam, the tail end of the lifting mechanism is connected to the crossbeam, and the telescopic end of the lifting mechanism is connected to the filter plate.

[0008] Preferably, the lifting mechanism is an electric push rod, a lifting cylinder or a telescopic cylinder.

[0009] Preferably, the crossbeam is rotatably connected to the column, so that the crossbeam can drive the lifting mechanism to rotate.

[0010] Preferably, a power device is provided on the column corresponding to the crossbeam, and the output end of the power device is connected to the crossbeam in a transmission manner to provide power for the crossbeam to rotate and thus drive the filter disc to flip.

[0011] Preferably, a knocking hammer is provided on the crossbeam corresponding to the filter disc, and the knocking hammer can knock and vibrate the filter disc to facilitate the rapid falling off of aluminum slag impurities on the filter disc.

[0012] The beneficial effects of the utility model are:

[0013] By setting a filter plate corresponding to the ladle diameter to remove slag from the aluminum liquid in the ladle, the coverage area of ​​the filter plate is increased, the impurity cleaning effect is improved, and the trouble of using a strainer to manually remove slag multiple times is avoided. The lifting mechanism drives the filter plate to complete the automatic lifting and removing slag action, reducing the labor intensity of manual slag removal by operators. In addition, operators can operate away from the slag removal site, which improves the problem of operators being exposed to dust for a long time and endangering their occupational health.

[0014] By rotatably connecting the crossbeam and the column, the crossbeam can drive the lifting mechanism to rotate, thereby driving the filter plate to flip to the vertical direction, which is convenient for quick dumping of aluminum slag impurities. The setting of the hammer further improves the dumping efficiency of aluminum slag impurities. The configuration of the power device enables the filter plate to automatically complete the flipping action, further reducing the labor intensity of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figure 1-2As shown, an automatic slag removal device for molten aluminum comprises a filter plate 1 arranged corresponding to the diameter of a ladle 6, the filter plate 1 is conical, and a filter hole 11 is provided on the filter plate 1, so that the molten aluminum without aluminum slag can pass through the filter hole 11 smoothly, and at the same time, the aluminum slag and other impurities are isolated on the filter plate 1. The filter plate 1 is connected to the frame 3 by a lifting mechanism 2 in a lifting manner. When in use, the filter plate 1 is lowered to below the liquid level of the molten aluminum in the ladle 6 by the lifting mechanism 2, and the impurities on the surface of the molten aluminum are guided by the conical filter plate 1 and float from the gap between the outer edge of the filter plate 1 and the inner wall of the ladle 6 to the upper part of the filter plate 1. After standing for a certain period of time, the lifting mechanism 2 drives the filter plate 1 to rise until it is separated from the liquid level of the molten aluminum, and the impurities in the molten aluminum are removed, and then the filter plate 1 is allowed to stand for a certain period of time, so that the molten aluminum adhering to the filter plate 1 can fully flow back to the ladle 6, and then the impurities in the filter plate 1 are transferred to the slag receiving trolley, and the slag removal operation of the molten aluminum is completed.

[0021] In this embodiment, the filter plate 1 is arranged corresponding to the diameter of the ladle 6 to perform slag removal on the aluminum liquid in the ladle 6, thereby increasing the coverage area of ​​the filter plate 1, improving the impurity cleaning effect, avoiding the trouble of using a strainer to manually remove slag multiple times in the traditional way, and the filter plate 1 is driven by the lifting mechanism 2 to complete the automatic lifting and removing slag action, thereby reducing the labor intensity of the operators. In addition, the operators can operate away from the slag removal site, thereby improving the problem of operators being exposed to dusty environments for a long time and endangering their occupational health.

[0022] As a preferred embodiment, the frame 3 includes a vertically arranged column 31, the top of the column 31 is connected to a crossbeam 32, the tail end of the lifting mechanism 2 is connected to the crossbeam 32, and the telescopic end of the lifting mechanism 2 is connected to the filter plate 1. The lifting mechanism 2 can be an electric push rod, a lifting cylinder or a telescopic oil cylinder.

[0023] Preferably, in order to facilitate the dumping of aluminum slag on the filter disc 1, the crossbeam 32 is rotatably connected to the column 31, so that the crossbeam 32 can drive the lifting mechanism 2 to rotate, thereby driving the angle of the filter disc 1 to flip to the vertical direction, which is convenient for dumping aluminum slag impurities.

[0024] Preferably, if Figure 2 As shown, a power device 4 is provided on the column 31 corresponding to the cross beam 32 , and the output end of the power device 4 is connected to the cross beam 32 in a transmission manner to provide power for the cross beam 32 to rotate and thus drive the filter disc 1 to flip.

[0025] In order to further improve the dumping efficiency of aluminum slag impurities, a knocking hammer 5 is provided on the crossbeam 32 corresponding to the filter disc 1, and the knocking hammer 5 can knock and vibrate the filter disc 1 to facilitate the rapid falling off of the aluminum slag impurities on the filter disc 1. When in use, the lifting mechanism 2 retracts, driving the filter disc 1 that has completed the slag removal to rise and contact the knocking hammer 5. After the aluminum liquid on the filter disc 1 has returned, the power device 4 is started, driving the crossbeam 32 to rotate and drive the filter disc 1 to flip, and the knocking hammer 5 is started. The hammer head of the knocking hammer 5 knocks and vibrates back and forth on the filter disc 1, so that the aluminum slag impurities adhering to the filter disc 1 fall off smoothly. The filter disc 1 that has completed the dumping of the aluminum slag impurities flips and resets under the drive of the crossbeam 32, and the slag removal operation continues after the next ladle 6 is in place.

[0026] The above disclosure is only a specific embodiment of the present patent, but the present patent is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, the deformation made should be deemed to belong to the protection of the present invention.
