DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0021] Combination Figure 1 A degassing, filtering and refining device for aluminum alloy liquid comprises a filter barrel 1, a degassing component 2 for degassing is fixedly connected to the upper end of the filter barrel 1, and a feed pipe 3 is fixedly connected to the upper end of the degassing component 2.

[0022] The utility model is further described below in conjunction with embodiments. Example

[0023] See also Figure 1 and Figure 3 A motor 5 is fixedly connected to the inner wall of the filter barrel 1, a rotating shaft 51 is fixedly connected to the output end of the motor 5, a toggle rod 6 is fixedly connected to one side of the rotating shaft 51, a spring 54 is fixedly connected to one side of the degassing component 2, and an arc block 53 is fixedly connected to one side of the spring 54.

[0024] Specifically, the aluminum alloy liquid enters the filter barrel 1 from the feed pipe 3, and the motor 5 drives the rotating shaft 51 to rotate, so that the toggle rod 6 contacts the arc block 53 to squeeze the spring 54. The arc block 53 has an arc, so that the toggle rod 6 can smoothly pass through the arc block 53 when in contact, and the spring 54 recovers its deformation when out of contact. At this time, the vibration caused by the bounce can vibrate the degassing component 2, reduce the blockage caused by waste chips during filtration, and improve work efficiency. Example

[0025] See also Figure 1-Figure 3, stirring rods 52 are fixedly connected to both sides of the rotating shaft 51, and a filter screen A7 is snap-connected inside the filter barrel 1. Two groups of filter screens A7 are fixedly connected, and one side of the two groups of filter screens A7 is fixedly connected to a fixed shaft 81, and one side of the fixed shaft 81 is fixedly connected to a sealing gasket 8. An air inlet 11, a feed port 12 and an air outlet 13 are opened at the upper end of the filter barrel 1, and the feed pipe 3 is connected to the filter barrel 1 through the feed port 12. An air pump 21 is fixedly connected to the upper end of the filter barrel 1, and an air inlet pipe 22 is fixedly connected to the air outlet end of the air pump 21, and a filter screen B23 is fixedly connected to the inner wall of the air inlet pipe 22, and an air outlet pipe 4 is fixedly connected to the inside of the air outlet 13. A connecting port 14 and a discharge port 15 are opened on one side of the filter barrel 1, and an insulation board 9 is fixedly connected to the inner wall of the filter barrel 1.

[0026] Specifically, the operation of the motor 5 drives the rotating shaft 51 to rotate, so that the stirring rod 52 stirs the aluminum alloy liquid to reduce uneven degassing, and the filter A7 can filter impurities in the aluminum alloy liquid. The fixed shaft 81 is pulled to allow the filter A7 to extend a portion of the filter barrel 1. At this time, a brush is used to extend from the connecting port 14 into the filter barrel 1 to clean the filter A7, thereby cleaning the filter A7. The sealing gasket 8 can improve the sealing performance of the filter barrel 1. The air pump 21 can blow nitrogen into the air inlet pipe 22, thereby removing the gas from the aluminum alloy liquid in the filter barrel 1. The gas brought out forms bubbles and is discharged from the air outlet pipe 4 to achieve degassing. The insulation board 9 can insulate the temperature in the filter barrel 1, so that the reaction in the filter barrel 1 is within the required temperature, reducing the reduction in degassing effect caused by temperature loss. The filter B23 can filter the aluminum alloy liquid and reduce the blockage of the air inlet pipe 22.
