Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, and more specifically, to a closed-type aluminum powder preliminary screening machine. Background Technology

[0002] Aluminum rods are rod-shaped or bar-shaped semi-finished products made of aluminum or aluminum alloys. They are a crucial product in the aluminum industry chain, connecting upstream and downstream processes. Made from molten aluminum through casting and rolling, they provide raw materials for subsequent deep processing. Before processing, aluminum rods require the recycling of scrap aluminum products, followed by crushing and screening.

[0003] Currently, the traditional preliminary screening of aluminum scrap typically uses a vibrating screen. The vibrating screen is equipped with a filter screen, forming two channels, upper and lower. During screening, the entire screening machine vibrates, driven by a vibrating motor, which sieves fine aluminum scraps and powder into the lower channel of the filter screen, while larger aluminum blocks and wires remain in the upper channel. After screening in this way, the scraps are finally discharged through two outlets at the output end.

[0004] However, the aforementioned vibrating screen has an open structure, which easily causes aluminum powder to fly around, resulting in a poor production environment. If the humidity is high, aluminum powder can easily adhere to the surface of the aluminum blocks, leading to incomplete screening. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] refer to Figure 1-2 A closed-type preliminary aluminum powder screening machine includes a base frame 1, a vibrating disc 2 elastically mounted on the base frame 1, a filter screen 3 dividing the disc 2 into upper and lower channels, and two discharge ports 21 communicating with the two channels at the output end of the disc 2. The machine also includes a cover 4, a feed channel 5, and a blower mechanism 6. The cover 4 is located on top of the disc 2, sealing the top of the disc 2. The feed channel 5 is connected to the cover 4 and located on the input side of the disc 2, used to feed material into the upper channel of the disc 2. The blower mechanism 6 has an air pipe 61 mounted on the cover 4 and located on one side of the feed channel 5, used to blow air onto the aluminum material entering from the feed channel 5.

[0020] Understandably, the machine cover 4 is a shielding component, which can be, for example, a plate structure or a cover structure that is integrally set with the machine plate 2 or detachably set, but is not limited to these. The feed channel 5 is a feed component, which can be, for example, a pipe or a funnel, but is not limited to these. The blower mechanism 6 is a blower component. Here, the blower pipe 61 can be connected to a blower, which can be natural wind or heated air. The base frame 1, the vibrating machine plate 2, and the filter screen 3 are existing technologies and will not be described in detail here.

[0021] With this configuration, the hood 4 can cover and seal the bottom of the disc 2, effectively preventing aluminum powder from flying and ensuring the cleanliness of the production environment. The air blower 61 directs air towards the aluminum material exiting the feed channel 5, blowing away the aluminum powder adhering to the aluminum blocks. The air blower also has a drying effect, removing moisture from the adhered aluminum powder, reducing its stickiness, and ensuring thorough subsequent vibratory screening. The filter material passes through the vibrating disc 2, filtering aluminum chips and powder into the lower channel of the disc 2, while larger aluminum blocks are intercepted in the upper channel of the disc 2 before being discharged through the two outlets 21.

[0022] Optionally, in some embodiments, the machine cover 4 includes a fixed shielding part 41 and a movable shielding part 42. The fixed shielding part 41 is fixedly disposed on the top of the input side of the machine tray 2. The movable shielding part 42 is unclamped on the top of the machine tray 2 and is located on the side of the fixed shielding part. Furthermore, the feed channel 5 and the air blowing pipe 61 are both disposed on the fixed shielding part 41.

[0023] Understandably, the fixed cover part 41 can be fixedly installed by means of integral installation or bolt locking. The movable cover part 42 can be connected by means of box door, drawer, etc., but is not limited to these.

[0024] With this configuration, the movable shield 42 can be opened at any time for easy observation and maintenance. When the movable shield 42 is opened, the fixed shield 41 can remain stationary, without affecting the use of the feed channel 5 and the air pipe 61.

[0025] Optionally, in some embodiments, the portions of the feed channel 5 and the blower 61 that connect to the fixed shielding portion 41 are both made of flexible telescopic tubes 7.

[0026] It is understandable that the flexible telescopic tube 7 can be made of corrugated pipe, fabric bag, etc., but is not limited to these.

[0027] With this configuration, when the entire disc 2 vibrates, the flexible telescopic tube 7 can act as a transition, so that the feed channel 5 and the blowing pipe 61, except for the part with the flexible telescopic tube 7, do not vibrate with the disc 2.

[0028] Optionally, in some embodiments, the air outlet of the blower pipe 61 is angled downwards. This allows the air to blow the aluminum material onto the filter screen 3 at an angle. Compared to a horizontal direct blow, this allows the aluminum material to fall onto the filter screen 3 more quickly for vibratory screening, ensuring thorough screening.

[0029] Optionally, in some embodiments, the screening machine further includes a support member 8 disposed on one side of the machine plate 2 and fixing the feed channel 5 and the blow pipe 61.

[0030] Understandably, the support component 8 is a supporting part, such as a frame structure, a bent arm structure, etc., but not limited to these. Here, if the flexible telescopic tube 7 has a certain length, the support component 8 can also be connected to the flexible telescopic tube 7, with a certain length reserved at the bottom of the flexible telescopic tube 7. The support component 8 can also be connected to other parts above the flexible telescopic tube 7.

[0031] With this configuration, the feed channel 5 and the blower pipe 61 can be supported and installed by the support member 8, so that they are stably positioned above the machine cover 4.

[0032] Optionally, in some embodiments, at least one baffle 43 is provided at the bottom of the cover 4, with a gap between the baffle 43 and the filter screen 3; and a protruding plate 31 that is misaligned with the baffle 43 is provided at the top of the filter screen 3.

[0033] Understandably, multiple baffles 43 and convex plates 31 can be set at intervals along the discharge direction of the machine disc 2.

[0034] With this configuration, the convex plate 31 can slightly obstruct the vibration transmission of the filter material, allowing the aluminum material to remain on the filter screen 3 for a longer period of time for vibration screening. It can also work with the baffle 43 to obstruct and block the air blown out by the blower mechanism 6, effectively reducing the possibility that the blower will directly blow fine aluminum powder out of the outlet 21.

[0035] Optionally, in some embodiments, the lower channel of the machine tray 2 is provided with a plurality of limiting members 91 at intervals along the discharge direction. The bottom of the limiting member 91 is spaced apart from the bottom of the machine tray 2, and the limiting member 91 divides the lower channel of the machine tray 2 into a plurality of cavities 92. Each cavity 92 is provided with an elastic ball 9. The distance between the limiting member 91 and the bottom of the machine tray 2 is smaller than the diameter of the elastic ball 9.

[0036] Understandably, the top of the limiting component 91 can be directly connected to the filter screen 3, or it can be spaced apart from the filter screen 3. The gap between the bottom of the limiting component 91 and the bottom of the machine plate 2 is to provide a channel for the vibration transmission of aluminum chips and aluminum powder. The limiting component can be a plate or a rod, etc., but is not limited to these.

[0037] With this setup, during the vibration of the machine disc 2, the elastic ball 9 can also vibrate along with the machine disc 2, and the elastic ball 9 can impact the filter screen 3 to clear the blocked filter holes on the filter screen 3, ensuring the screening capacity of the filter screen 3 at all times.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
