Sealing devices for a drum, and an aluminum scrap pre-treatment system according to some embodiments of the present invention are described below with reference to fig. 1 to 7.
Some embodiments of the present application provide a sealing arrangement 10 for a drying drum.
As shown in fig. 1 and 2, the sealing device 10 of the drying drum includes a housing 11 and an impeller 12.
The casing 11 is provided with a first opening 111 and a second opening 112, the second opening 112 is located below the first opening 111, and the impeller 12 is provided in the casing 11 and located between the first opening 111 and the second opening 112. When second opening 112 is in butt joint with charging opening 21 of drying drum 400, impeller 12 covers charging opening 21, and the possibility and the overflow amount of flue gas generated in drying drum 400 from charging opening 21 can be reduced, so that a certain sealing effect is achieved.
In addition, the impeller 12 can rotate, so that the impeller 12 transfers the material to be dried from the upper position of the impeller 12 to the lower position through continuous rotation, and the material to be dried falls into the drying cylinder 400 under the action of gravity, so that the material to be dried is held in the drying cylinder 400. In this way, the rotation of the impeller 12 allows the sealing device 10 to be used for blocking the smoke and charging the drum 400 at the same time, ensuring the continuous operation of the drum 400.
The sealing device 10 in this embodiment can effectively reduce the possibility of the flue gas overflowing from the charging opening 21 of the drying drum 400, and reduce the environmental pollution caused by the flue gas emission. Meanwhile, the heat loss caused by the overflow of the high-temperature flue gas can be reduced, the energy is saved, and the effect of saving the cost can be achieved.
In some embodiments, as shown in fig. 1 and 3, the impeller 12 includes a plurality of blades 121 disposed along a circumferential direction of a rotation axis of the impeller 12, and two adjacent blades 121 cooperate to form the blade groove 122.
Through two adjacent blades 121 and the casing 11, the blade groove 122 is defined, the blade groove 122 does not need to be separately arranged, the structure of the impeller 12 is simplified, meanwhile, the blade groove 122 can be defined by two adjacent blades 121, so that the impeller 12 is provided with a plurality of blade grooves 122 distributed along the circumferential direction of the rotation axis, and thus, the material to be dried can uninterruptedly move from the first opening part 111 to the second opening part 112, and further, the material to be dried continuously in the drying cylinder 400 is supplemented, and the working efficiency of the drying cylinder 400 is improved. Wherein the number of blades 121 is 4, 6, 8 or others.
In some embodiments, the plurality of blades 121 are equally spaced.
In some embodiments, as shown in fig. 3, the cross-section of two adjacent blades 121 is V-shaped along a direction perpendicular to the rotation axis of the blades 121.
The V-shaped blade groove 122 is formed by arranging the cross section of two adjacent blades 121 in a V shape, and the notch of the V-shaped blade groove 122 faces the first opening portion 111 or the second opening portion 112, and the size of the notch is larger than the first opening portion 111 and the second opening portion 112, so that the V-shaped blade groove 122 plays a role of sealing. By forming the cross section of two adjacent vanes 121 in a V shape, a plurality of V-shaped vane grooves 122 are formed, so that at least two vanes 121 are located at opposite positions on the inner wall of the casing 11 during 360-degree rotation of the impeller 12, and the communication between the first opening portion 111 and the second opening portion 112 is blocked, thereby improving the sealing performance of the sealing device 10.

By setting the rotating speed of the impeller 12, the operating speed of the material to be dried can be reasonably controlled, and the feeding speed of the drying cylinder 400 is rationalized. The rotating speed is prevented from being too fast, the possibility that the material to be dried is interfered with the shell 11 when entering the first opening part 111 is reduced, and the rotating speed is prevented from being too slow, so that the material to be dried is too much and overflows the blade grooves 122. Thereby improving the reliability of the seal device 10 by controlling the rotational speed of the impeller 12. The rotation speed of the impeller 12 is preferably 9 revolutions per minute. Of course, 8 cycles/minute, 12 cycles/minute, etc. are also possible.
