The guide member 4 includes a guide plate 41 fixedly connected to the rotating frame 21. It is particularly noteworthy that there are four guide plates 41, and the four guide plates 41 are all at the diagonal positions of the rotating frame 21. At the same time, the output ends of two adjacent guide plates 41 are located on both sides of the strip opening of the conveying pipe 31, which further enables impurities to enter the conveying pipe 3 with the assistance of the guide plate 41, and one end of the guide plate 41 is inlaid with a plurality of conveying The balls 42 in contact with the tube 31 are all wrapped with a high-temperature resistant layer 43.

The side walls of the ring 77 are fixedly connected with a spring seat 78. It is particularly noteworthy that the spring seat 78 includes a spring and a movable seat matching the through hole 76, and the spring is connected to the limiting ring 77. A clamping rod 79 is passed through the spring seat 78. One end of the clamping rod 79 passes through the limiting ring 77 and extends to the outside of the fixed column 72. One end of the clamping rod 79 is sharp, and the movable seat is sleeved on the clamping rod 79. One end of the clamping rod 79 is fixedly connected with an arc ball 710 in contact with the screw 74, and the inner bottom of the fixed column 72 is connected with a rotating seat 711 in contact with the screw 74.

[0027] When the device starts to run, the aluminum liquid that has been processed externally will first enter the rotating frame 21 from the conveying channel 55. It is particularly noteworthy that one end of the conveying channel 55 extends into the rotating frame 21, and the rotation of the rotating frame 21 will not affect the normal use of the conveying channel 55. The guide plate 41 will not contact the conveying channel 55, so the guide plate 44 will not affect the normal use of the conveying channel 55. When the aluminum liquid enters the rotating frame 21, the aluminum liquid will contact the foam ceramic filter plate 22, and then under the influence of gravity, the aluminum liquid will filter the foam ceramic filter plate 22, and then the aluminum liquid will enter the conveying plate 51. It is particularly noteworthy that the conveying plate 51 is tilted so that the aluminum liquid can enter the output port position of the box body 1, thereby allowing the aluminum liquid to enter the output channel 56 from the output port position of the box body 1, and then the filtered aluminum liquid will proceed to the next processing step. In this process, it is particularly noteworthy that the first heat insulation plate 52 can prevent the heat of the conveying plate 51 from being transferred to the bottom of the rotating disk 218, further protecting the rotating disk 218, and the second heat insulation plate 54 can prevent the heat from being transferred to the first gear 213, further protecting the first gear 213, and the blocking plate 53 can effectively prevent the aluminum liquid from leaking, further ensuring the normal filtration of the aluminum liquid, so that the device can be used normally.

[0028] When the staff needs to replace the foam ceramic filter plate 22, the staff can directly start the first motor 215. When the first motor 215 is working, the second gear 214 can be rotated, and the first gear 213 can be further rotated, so that the rotating frame 21 can be rotated. It is particularly noteworthy that with the assistance of the first support rod 212, the first annular guide rail 211, the second support rod 217, the second annular guide rail 216 and the rotating disk 218, the rotating frame 21 can be rotated more stably, and the foam ceramic filter plate 22 at the bottom can be rotated to the top. After waiting for a while, the staff can insert the fixing column 72 into the fixing hole 23, and then the staff can rotate again. Rotate the screw 74 into the placement hole 73 so that the screw 74 can move in the thread direction of the nut 75, so that the screw 74 can continue to move downward, so that the arc ball 710 can be squeezed, so that the clamping rod 79 can move to one side, and the movement of the clamping rod 79 can cause one end of the clamping rod 79 to be stuck on the side wall of the fixing hole 23. Then the staff rotates the fixing screw 25 again, so that the staff can remove the limit frame 24. After that, the staff can tie the rope to the fixed column 72, and then start the peripheral lifting equipment, so that the foam ceramic filter plate 22 can be taken out from the rotating frame 21, further facilitating the staff to replace the new foam ceramic filter plate 22, thereby facilitating the staff's replacement work.

[0029] It is particularly noteworthy that when replacing the foam ceramic filter plate 22, the staff can lightly knock on the foam ceramic filter plate 22. At this time, the impurities adhering to the foam ceramic filter plate 22 will fall due to the influence of gravity. In this way, the impurities can enter the strip opening on the conveying pipe 31 with the assistance of the guide plate 41. At this time, the second motor 36 is working. When the second motor 36 is working, with the assistance of the transmission assembly 35, the rotating rod 33 can be rotated, and the Jiaolong conveying blade 34 can be further rotated, so that the impurities can be transported to the discharge pipe 32. This can facilitate the staff to clean the impurities and further avoid the contamination of the aluminum liquid.

[0030] It is particularly noteworthy that when the guide plate 41 rotates, the ball 42 can ensure the normal rotation of the guide plate 41, and the blocking brush 45 can prevent impurities from adhering to the ball 42. It is particularly noteworthy that the heat-conducting arc sheet 413 on the heat-conducting steel plate 411 below can absorb the temperature emitted by the aluminum liquid, and with the assistance of the heat-conducting rod 414, the heat-insulating cylinder 415 and the conduction rod 416, the heat can be transferred to the other part of the heat-conducting steel plate 411, so that the other foam ceramic filter plate 22 can be preheated. During this process, the staff can start the external air pump and the electric heating tube 63, so that the gas can be ejected from the air outlet plate 62. When the gas passes through the electric heating tube 63, the gas can be heated, and the heat absorption plate 65 can absorb the heat of the electric heating tube 63, which not only heats the gas again, but also preheats the foam ceramic filter plate 22, further ensuring that the staff can use the foam ceramic filter plate 22, reducing the preheating time, and further improving the efficiency of installation and replacement.
