Based on a second embodiment provides a sweeps recovery processing device for aluminum alloy processing, because the rotation of a sieve section of thick bamboo 6 self sieves the aluminum alloy waste material through the sieve mesh, and the rotation of material blade 16 is dialled to the spiral is pay-off the waste material, consequently in the in-service use in-process can not avoid taking place the waste material card to advance in the sieve mesh and adhere to and dial material blade 16 surface at the spiral, if not detach the waste material as early as possible, not only can cause this batch of waste material not abundant to sieve, equally still can influence and sieve next batch of waste material, simultaneously because the high-speed screening of a sieve section of thick bamboo 6, make the waste material after the screening unsmooth in unloading in guide chamber 20 lead to blockking up, the waste material after the screening is piled up in screening 5 bottoms in a large number, influence subsequent screening work, in order to solve this problem, this kind of sweeps recovery processing device for aluminum alloy processing: the cleaning shaft tube 13 is a hollow tubular structure with an opening at one end and a closed end, the outer surface of the cleaning shaft tube 13 is provided with a plurality of inner cleaning spray holes 15 distributed in a circumferential array, when the spiral material shifting blade 16 needs to be cleaned, the main driving motor 14 drives the spiral material shifting blade 16 to move at a high speed, the residual scraps on the spiral material shifting blade 16 can be automatically separated by a centrifugal principle through the high-speed movement, the cleaning shaft tube 13 passes through the positioning seat 12 and is rotatably connected with the air pumping box 35 through a second bearing, the outer surface of the cleaning shaft tube 13 positioned inside the air pumping box 35 is provided with a fan blade 36, the air inlet end of the air pumping box 35 is communicated with the first air tube 23, the other end of the first air tube 23 passes through the sealing door 34 and is positioned at the discharge port of the guide cavity 20, so that the cleaning shaft tube 13 rotates to drive the fan blade 36 to rotate, and the air in the, when the spiral material stirring blade 16 moves at a high speed, gas in the air pumping box 35 enters the screen drum 6 along the inner cleaning spray hole 15, then the separation effect of residual scraps on the spiral material stirring blade 16 is effectively improved, the upper surface of the screening shell 5 is communicated with the outer cleaning spray pipe 18, a plurality of spray holes which are distributed in a linear array mode and have the air outlet direction in the vertical downward direction are formed in the bottom of the outer cleaning spray pipe 18, the top of the outer cleaning spray pipe 18 is provided with a second air pipe 24, the other end of the second air pipe 24 penetrates through a sealing door 34 and is located at the bottom of a compression cavity 25, when the screening mechanism 3 stops working and the compression assembly 27 works, the gas in the compression cavity 25 enters the screening shell 5 along the second air pipe 24 and the outer cleaning spray pipe 18, and the screen drum 6 is subjected to wind power blockage removal, and the smoothness of screen holes in the screen.

In the using process of the device, because the screen cylinder 6 screens the aluminum alloy waste, the screen holes are not free to block due to long-time work, thereby reducing the screening effect, meanwhile, because the long-time work of the spiral material shifting blade 16 also causes partial waste to be attached to the surface of the screen holes, thereby hindering the feeding work of the subsequent waste, the problem must be solved, the screening work can be ensured to be carried out efficiently, when the main driving motor 14 rotates, the cleaning shaft tube 13 rotates, the fan blade 36 at the other end of the cleaning shaft tube 13 rotates, so that the air suction box 35 is in an air suction state, because the air inlet of the air suction box 35 is communicated with the discharge hole of the material guide cavity 20 through the first air pipe 23, the air in the material guide cavity 20 enters the air suction box 35 along the first air pipe 23, at the moment, the cavity 20 is in a high-speed flowing state, because the waste particles screened from the first screen hole area 7, the second screen hole area 8 and the third screen hole area 9 fall into the bottom, and enters the compression cavity 25 along the inclined material guiding cavity 20, under the action of the high-speed wind, the flowing speed of the waste particles in the material guiding cavity 20 can be increased, so that the waste particles can enter the compression cavity 25 more quickly, the situation that the subsequent screening work of the screen cylinder 6 is influenced due to the blocking phenomenon caused by the slow blanking at the bottom of the screening shell 5 is prevented, the air in the air pumping box 35 enters the inside of the cleaning shaft tube 13 under the rotation of the fan blades 36 and is continuously blown out from the inner cleaning spray hole 15 in combination with the centrifugal force generated by the high-speed rotation of the spiral material stirring blade 16, so that the wind power impurity removal is continuously carried out on the outer surface of the spiral material stirring blade 16, the situation that the feeding is not smooth and the subsequent screening work is influenced is prevented due to too much waste attached to the outer surface of the spiral material stirring blade 16, when the screening mechanism 3 stops working and the compression assembly 27 works, the extrusion plate 32 slides in the, the problems that the extrusion difficulty of the extrusion plate 32 for the waste is increased, the compaction degree of the waste is too low, the subsequent loading and unloading are difficult and the like due to the fact that air in the compression cavity 25 is not circulated are avoided by setting the second air pipe 24, air in the outer cleaning spray pipe 18 not only unblocks a blocked sieve pore in the sieve cylinder 6 through the spray holes to avoid influencing the screening work after the sieve cylinder 6, but also clears away waste attached to the outer surface of the spiral stirring blade 16 to achieve multi-directional impurity removal, meanwhile, small particle dust impurities and the like in the screening shell 5 fly to the top due to continuous air blowing of the inner cleaning spray hole 15 and even fly out of the screening shell 5 along the feed hopper 17 to cause air pollution, so that the inner impurities can effectively fall to the bottom of the screening shell 5 to be recovered through the downward wind power of the outer cleaning spray pipe 18 to prevent the inner impurities from flying into the outside air to cause pollution, influence operating personnel health even, the effectual inside wind-force circulation of device that utilizes of the device, not only accomplish to sieve 3 interior waste materials of mechanism prevent stifled antiseized, in order to cause the influence to follow-up work, reduce the screening effect, damage the device, can also accelerate in the waste material entering compression chamber 25 in the guide chamber 20, it is smooth and easy to guarantee that the inside waste material of device flows, can not cause the jam, make things convenient for the inside compaction work that carries on of compression chamber 25 simultaneously, the screening efficiency of device has been improved greatly, guarantee that the device is in a benign unblocked operating condition constantly.
