DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1 As shown, the aluminum material dry screening device for preventing aluminum material from popping out includes a feed hopper 1 and a rolling dry screen drum 4. A conveyor belt 3 is provided between the feed hopper 1 and the rolling dry screen drum 4. The feed hopper 1 has a feed port 11 at the top and a discharge port at the bottom (not shown in the figure due to viewing angle). The operator puts the aluminum material that needs to be cleaned of dust into the feed hopper 1 through the feed port 11. A vibrating feeder 2 is provided below the discharge port of the feed hopper 1. The top wall of the main body of the vibrating feeder 2 has a feed port 21 and the bottom wall has a feed port (not shown in the figure due to viewing angle). The feed port 21 of the vibrating feeder 2 is aligned upward with the discharge port of the feed hopper 1, and the aluminum material in the feed hopper 1 falls down and enters the vibrating feeder 2 through the feed port 21. The feed port of the vibrating feeder 2 is aligned downward with the rear end of the conveyor belt 3. The vibrating feeder 2 includes a vibrating motor (not shown in the figure due to the viewing angle), which drives the main body of the vibrating feeder 2 to vibrate so that the aluminum material inside it is shaken off from its feeding port to the rear end of the conveyor belt 3. The feed hopper 1 slowly and continuously feeds the aluminum material onto the conveyor belt 3 through the vibrating feeder 2 to avoid too much aluminum material being accumulated on the conveyor belt 3 at once. The rear end of the conveyor belt 3 receives the aluminum material from below the feeding port of the vibrating feeder 2, and the front end is connected to the feeding port 41 of the rolling dry screen drum 4. The conveyor belt 3 rotates to drive the aluminum material at its rear end to move forward to the front end. Since the feeding port 41 of the rolling dry screen drum 4 is higher than the feeding port of the vibrating feeder 2, and the rear end of the conveyor belt 3 is lower than the front end, during the aluminum material transmission process, the aluminum material may slide backwards, causing a large amount of aluminum material to accumulate at a certain position of the conveyor belt 3, resulting in excessive pressure on the conveyor belt 3, affecting the normal operation of the conveyor belt 3. To this end, in this embodiment, a plurality of anti-slip plates 31 are arranged evenly at intervals on the surface of the conveyor belt 3 to prevent the aluminum material from sliding backwards. This can avoid a large amount of aluminum material from accumulating at a certain position of the conveyor belt 3 and avoid the problem of excessive local pressure.

[0021] The rolling dry screen drum 4 lies on the front side of the conveyor belt 3. The rolling dry screen drum 4 is as shown in FIG. Figure 2 As shown, the feed port 41 is provided with an oblique guide groove 6 with a rear side higher than the front side. The rear end of the oblique guide groove 6 is located below the front end of the conveyor belt 3 to receive the aluminum material conveyed by the conveyor belt 3. The front end of the oblique guide groove 6 extends into the rolling dry screen cylinder 4 through the feed port 41 to guide the aluminum material into the rolling dry screen cylinder 4. When the aluminum material rolls down from the oblique guide groove to the rolling dry screen cylinder, it may bounce up. For this reason, the embodiment Figure 2 and Figure 4As shown, a vertical stopper 61 extends downward from the front end of the oblique guide groove 6, extending to the bottom wall of the rolling dry screen cylinder 4, preventing the aluminum material from popping out from the rolling dry screen cylinder 4. An annular stopper 44 extends from the inner peripheral side wall of the cylinder to the central axis of the circumferential cylinder at the feed port 41 of the rolling dry screen cylinder 4, and the end edge of the stopper 44 serves as the bottom edge of the feed port 41. The vertical stopper 61 at the front end of the oblique guide groove 6 fits the stopper 44 and extends to the root where the stopper 44 is connected to the bottom wall of the rolling dry screen cylinder 4. The annular stopper 44 and the vertical stopper 61 of the oblique guide groove 6 prevent the aluminum material from popping out from the rolling dry screen cylinder 4. The annular stopper 44 and the vertical stopper 61 are made of elastic material. Compared with hard materials, even if they are deformed by the rebound and impact of the aluminum material, they can automatically recover without causing irreversible depression, thereby preventing the annular stopper 44 and the vertical stopper 61 from causing irreversible depression and affecting the rotation of the rolling dry screen cylinder 4. It is not preferred that if the rolling dry screen drum 4 does not rotate 360°, the feed port 41 of the rolling dry screen drum 4 can be changed to only extend a baffle 44 upward from the lower side wall of the drum, for example, the baffle 44 can be changed to a semi-annular shape, as long as the baffle 44 is wider than the oblique guide groove 6. Under this structure, the rolling dry screen drum can rotate only when the baffle 44 is ensured to fit the vertical baffle 61. Figure 3 As shown, the circumferential side wall of the body 40 of the rolling dry screen drum 4 is provided with sieve holes 42 for screening out the aluminum material, and the rolling dry screen drum 4 includes a rotary motor (not shown in the figure) which drives the body 40 of the rolling dry screen drum 4 to rotate through a gear transmission mode, and the body 40 of the rolling dry screen drum 4 rotates to perform rolling dry screening on the aluminum material in the drum. The rolling dry screen 4 includes a recovery cover 44 sleeved outside the body 40, and the bottom of the recovery cover 44 is provided with four recovery channels 441. The rolling dry screen drum 4 is provided with four material receiving frames 43 respectively below the four recovery channels 441, and the aluminum material is screened out from the sieve holes 42 of the drum dry screen drum 4 and falls into the material receiving frames 43 through the recovery channels 441 of the recovery cover 44.

[0022] The aluminum material dry screening device of the present embodiment can perform rolling dry screening on the aluminum material, so that the dust on the surface of the aluminum material is separated from the aluminum material, thereby cleaning the dust on the surface of the aluminum material. However, the dust on the surface of the aluminum material will be blown into the air after being separated from the aluminum material. In order to reduce the impact on the air quality, the aluminum material dry screening device of the present embodiment includes a dust suction fan 5. Considering that the vibrating feeder 2 will cause a part of the dust on the surface of the aluminum material to be separated from the aluminum material when vibrating the feeder, and the rolling dry screen cylinder 4 drives the aluminum material to roll, the dust on the surface of the aluminum material is further separated from the aluminum material. Therefore, the dust suction fan 5 is provided with a first dust suction pipe 53 and a second dust suction pipe 57. The terminal end of the first dust suction pipe 53 is connected to the dust suction hood 54 arranged above the feed port 41 of the rolling dry screen cylinder 4 to suck away the dust discharged from the feed port 41 of the rolling dry screen cylinder 4. The end of the second dust suction pipe 57 is connected to the dust suction hood 56 arranged beside the vibrating feeder 2. A vent 22 is provided on the side of the vibrating feeder 2 near the end of the second dust suction pipe 57 for dust discharge. The dust suction fan can suck away the dust discharged from the feed port 21, the feed port and the vent 22 on the side wall of the vibrating feeder 2 through the dust suction hood 56. Considering that dust may fly out from the sieve holes when the rolling dry screen drum 4 drives the aluminum material to roll dry screen, and dust may also be raised when the aluminum material is put into the feed hopper 1, the dust suction fan 5 is provided with a third dust suction pipe 51 and a fourth dust suction pipe 52. The end of the third dust suction pipe 51 is connected to the feed hopper 1 to suck the dust into the hopper 1. The end of the fourth dust suction pipe 52 is connected to the recovery hood 44 sleeved on the outside of the cylinder body of the rolling dry screen drum 4 to suck away the dust discharged from the sieve holes of the rolling dry screen drum 4.

[0023] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
