Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid treatment technology, specifically to an aluminum liquid degassing device. Background Technology

[0002] Molten aluminum refers to the liquid state formed after aluminum melts at high temperature. Molten aluminum mainly exists in the liquid aluminum inside the equipment during the operation of aluminum electrolysis. The gas in molten aluminum is mainly hydrogen, accounting for about 85% of the total gas. The higher the melting temperature, the higher the solubility of hydrogen in molten aluminum. However, the solubility in solid aluminum is very low. Therefore, during the solidification process, hydrogen will precipitate and form pores.

[0003] According to a search of Chinese patent number 201921852372.1, which describes an aluminum liquid degassing box and aluminum liquid degassing equipment, existing methods for degassing aluminum liquid often use cylindrical stirring rollers inside the mixing tank. This results in a limitation on the diameter of the stirring rollers, which are used to stir the aluminum liquid with different concentrations. Consequently, the stirring rollers with the same force are not able to stir the aluminum liquid with higher concentrations properly, thus affecting the degassing quality. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum liquid degassing device to address the shortcomings of existing technologies and solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum liquid degassing device, comprising a tank, a heating pump detachably connected to the bottom surface of the tank, and an air inlet pipe detachably connected to the end of the heating pump, a top cover detachably connected to the top of the tank, and a motor installed at the center of the upper surface of the top cover, the output shaft of the motor extending into the interior of the top cover, and an agitator roller installed at the end of the output shaft of the motor, the agitator roller extending into the interior of the tank, and a bearing installed at the bottom interior of the tank, the bearing being mounted on the end surface of the agitator roller.

[0006] As a preferred technical solution of this utility model, a pad is installed inside the center of the upper surface of the top cover, and the pads are distributed at different heights. The bottom of the motor is mounted on the pads, which can effectively ensure the stability of the center of gravity of the entire device and meet the requirements of long-term use of the device.

[0007] As a preferred technical solution of this utility model, the surface of the stirring roller is fitted with several bases, and each base is distributed at equal intervals on the surface of the stirring roller, which more efficiently enhances the matching and coordination of various components during the operation of the overall device and effectively reduces the probability of various unexpected situations that may occur during use.

[0008] As a preferred technical solution of this utility model, an extension shaft is inserted into the inside of the stirring roller, and several mounting blocks are simultaneously installed on the surface of the extension shaft and the surface of the base. By matching the various components of the overall device during use, the coordination of the overall device is enhanced.

[0009] As a preferred technical solution of this utility model, the surface of the mounting block is hinged with hinge shafts by screws, and there are several groups of hinge shafts. Each group has two hinge shafts distributed in opposite directions, which greatly enhances the fit strength of the overall device during use and avoids the situation of asymmetrical component matching during the use of the overall device.

[0010] As a preferred technical solution of this utility model, each of the hinge shafts has a mounting block installed at both ends, and the surface of the outer mounting block is hinged with an expansion plate by screws. The expansion plate is located on the surface of the stirring roller and above the corresponding base. According to the existing structure, they jointly support the overall device, enhance the coordination performance of the overall device during use, and enhance the durability of the overall device during use.

[0011] As a preferred technical solution of this utility model, a bolt is installed at the center of each set of hinge shafts, and the hinge shafts are distributed in an "X" shape through the bolts. By enhancing the flexible control capability of the overall device, the probability of the overall device malfunctioning during use is reduced.

[0012] As a preferred embodiment of this utility model, a motor mounting base is installed at the center of the upper surface of the top cover, and the motor is fixedly installed inside the motor mounting base to provide stable support for the motor.

[0013] As a preferred embodiment of this utility model, the minimum distance between the expansion piece and the tank body is greater than zero centimeters, so as to avoid the expansion piece colliding with the inner wall of the tank body.

[0014] As a preferred embodiment of this invention, the number of expansion plates on the outer side of each extension shaft is greater than three, and they are arranged in a circular array on the outer side of the extension shaft with the extension shaft as the axis.

[0015] The beneficial effects of this utility model are:

[0016] This aluminum liquid degassing device uses a motor to drive an agitator roller to rotate inside the tank. The motor lowers the roller, causing the extension shaft at the top to move downwards. This change in the position between the extension shaft and the base, along with the hinge shaft driven by the mounting block, merges the rollers, which in turn causes the expansion plates to extend and retract. This allows for flexible control of the entire device, enhancing its practicality. It overcomes the shortcomings of existing aluminum liquid degassing devices, which often use cylindrical agitators and are not suitable for comprehensive agitation of the aluminum liquid during replacement. This device increases the agitation intensity during the degassing process and enhances the effect of hydrogen precipitation from the aluminum liquid. Attached Figure Description

[0024] like Figure 1-4As shown, this embodiment of an aluminum liquid degassing device includes a tank 1. A heating pump 2 is detachably connected to the bottom surface of the tank 1, and an air inlet pipe 12 is detachably connected to the end of the heating pump 2. Steam is supplied to the inside of the tank 1 through the air inlet pipe 12 for heating. A top cover 3 is detachably connected to the top of the tank 1, and a motor 4 is installed at the center of the upper surface of the top cover 3. The motor 4 drives a stirring roller 5 to rotate and stir. The output shaft of the motor 4 extends into the inside of the top cover 3, and the stirring roller 5 is installed at the end of the output shaft of the motor 4. The stirring roller 5 extends into the inside of the tank 1. A bearing is installed at the bottom of the inside of the tank 1, and the bearing is installed on the end surface of the stirring roller 5. The end of the stirring roller 5 is fixed by the bearing to stabilize the rotation speed of the stirring roller 5.

[0025] Furthermore, a pad is fitted inside the center of the upper surface of the top cover 3, and the pads are distributed at different heights. The bottom of the motor 4 is mounted above the pads, and the motor 4 provides power for the operation of the stirring roller 5.

[0026] Furthermore, several bases 10 are snapped onto the surface of the stirring roller 5, and each base 10 is distributed at equal intervals on the surface of the stirring roller 5. The extension plate 11 is controlled to extend by matching the bases 10 with the extension shaft 6.

[0027] Furthermore, an extension shaft 6 is inserted inside the stirring roller 5, and several mounting blocks 7 are simultaneously installed on the surface of the extension shaft 6 and the surface of the base 10. The hinge shaft 8 is installed on the inner surface of the expansion plate 11 and the surfaces of the base 10 and the extension shaft 6 using the mounting blocks 7.

[0028] Furthermore, the surface of the mounting block 7 is hinged with hinge shafts 8 by screws, and there are several groups of hinge shafts 8. Each group has two hinge shafts 8 distributed in opposite directions. The expansion plate 11 is controlled to expand and contract by the relative movement of the hinge shafts 8.

[0029] Furthermore, each hinge shaft 8 has a mounting block 7 installed at both ends, and the surface of the outer mounting block 7 is hinged with an expansion plate 11 by screws. The expansion plate 11 is located on the surface of the stirring roller 5 and above the corresponding base 10. The expansion plate 11 enhances the stirring diameter that the stirring roller 5 can influence.

[0030] Furthermore, a bolt 9 is installed at the center of each set of hinge shafts 8, and the hinge shafts 8 are distributed in an "X" shape through the bolts 9, so that the expansion of the hinge shafts 8 provides power and support for the expansion plate 11 to be extended and retracted.

[0031] Furthermore, a motor mounting bracket is installed at the center of the upper surface of the top cover 3, and the motor 4 is fixedly installed inside the motor mounting bracket.

[0032] Furthermore, the minimum distance between the expansion plate 11 and the tank body 1 is greater than zero centimeters.

[0033] Furthermore, the number of expansion plates 11 on the outside of each extension axis 6 is greater than three, and they are arranged in a circular array on the outside of the extension axis 6 with the extension axis 6 as the axis.

[0034] The usage method of this embodiment is as follows: When using it, please refer to... Figure 1-4 First, the operator needs to manually open the top cover 3 of the tank 1, pour the molten aluminum into the tank 1 for storage, and then close the top cover 3 to allow for the heating reaction, so that the hydrogen content in the molten aluminum can be released as much as possible. During the heating reaction, the operator first manually turns on the heating pump 2, so that the heating pump 2 transmits the steam delivered by the air inlet pipe 12 into the tank 1. The steam is used to heat the molten aluminum inside the tank 1. Depending on the current needs, the operator manually controls the height of the motor 4 on the top cover 3. When the concentration of the molten aluminum inside the tank 1 is high, the operator controls the extension shaft 6 to move downward inside the stirring roller 5. This causes the mounting block 7 installed on its surface to move downward synchronously, thereby driving the hinge shaft 8 to drive the expansion plate 11 to extend outward, thus widening the diameter of the stirring roller 5, which facilitates the thorough stirring of molten aluminum of different concentrations.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
