DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 15 The present invention provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, it includes a primary screening mechanism 1, which is used for preliminary screening of black powder and aluminum powder; A sorting mechanism 3, which uses airflow to finely screen black powder and aluminum powder; The bottom of the primary screening mechanism 1 is fixedly connected with a bracket 2 and a flow pipe 4, the outer side of the bracket 2 is fixedly connected with the sorting mechanism 3, and the outer side of the sorting mechanism 3 is fixedly connected with the flow pipe 4; A fan 5 is fixedly connected to the side of the flow tube 4 away from the sorting mechanism 3, a control terminal 6 is fixedly installed on the top of the fan 5, and an infrared sensor 7 is fixedly installed on the top of the inner cavity of the flow tube 4; The sorting mechanism 3 includes a cyclone separation tank 31, which is fixedly connected to the circulation pipe 4 and the two are interconnected. The top of the cyclone separation tank 31 is fixedly connected with an outlet pipe 32, and the inside of the cyclone separation tank 31 is fixedly installed with a spiral sheet 33. The bottom of the cyclone separation tank 31 is fixedly connected with a support plate 34, and the support plate 34 is fixedly connected to the outside of the bracket 2. The black powder mixed with a small amount of aluminum powder flowing through the circulation pipe 4 will be sensed by the infrared sensor 7. At this time, the infrared sensor 7 will receive the signal and transmit it to the control terminal 6. Then the control terminal 6 will judge the signal and finally instruct the fan 5 to start. Then the fan 5 will generate wind force and blow the mixed powder into the cyclone separation tank 31. At this time, the gas containing the mixed material enters the cyclone separation tank 31 at a higher speed along the tangential direction. The design of this tangential inlet makes the gas start to rotate as soon as it enters the separator, forming an external cyclone airflow. Due to gravity, the separated aluminum powder eventually flows out from the bottom of the cyclone separation tank 31. An upward inner vortex is formed in the central part of the cyclone separation tank 31. The airflow of the inner vortex is relatively clean, so that the black powder with small gravity is discharged upward along with the inner vortex.

If a large amount of aluminum powder enters the circulation pipe 4, the movable screen 10 will be moved downward along the built-in rail 19. At this time, there will be an intersection between the movable screen 10 and the fixed screen 18, causing the space of the circulation hole to be reduced, thereby increasing the filtering effect of aluminum powder.

[0038] The equalizing component 13 includes a feed pipe 131, which is fixedly connected to the screening box 11. The inner side of the screening box 11 is fixedly connected with a rotating shaft 132, and the outer side of the rotating shaft 132 is rotatably connected with a four-division rotating plate 133.

The equalizing plate 135 is slidably adapted inside the four-division rotating plate 133, and the end of the equalizing plate 135 away from the internal spring 134 is fixedly connected with an elastic sheet 136. By pouring the mixture of black powder and aluminum powder from the feed pipe 131, the mixture will be pulled out due to gravity. The equilibrating plate 135 will slide down and hit the four-division rotating plate 133 and the equilibrating plate 135, so that the four-division rotating plate 133 will rotate clockwise through the rotating shaft 132, and the equilibrating plate 135 connected to the four-division rotating plate 133 through the internal spring 134 will also rotate accordingly, and in the process of rotating to the bottom, the internal spring 134 will be stretched, and at the same time, the equilibrating plate 135 will extend out of the four-division rotating plate 133, so that the elastic sheet 136 fixedly connected to the other end thereof will rub the top of the movable screen 10, thereby achieving the effect of uniformly conveying the mixed powder and avoiding uneven accumulation during the conveying process and affecting the degree of filtration.

[0039] A partition rod 102 is fixedly connected to the top of the inner cavity of the screening box 11, and a No. 1 dust suppressing plate 103 and a No. 2 dust suppressing plate 104 are respectively arranged on both sides of the partition rod 102.

If the mixed powder accumulates or gets blocked at the tail of the movable screen 10, a large amount of mixed powder will stay on the reset plate 100, and then the squeezed reset plate 100 will be deflected downward through the connecting shaft inside the support 109, and the toughness sheet 1001 will also be compressed until the accumulated part of the mixed material is discharged downward, wherein the reset plate 100 has the function of automatic reset. If too much mixed material is accumulated, the electric telescopic rod 176 is started, so that the inclined scraper 177 connected to its output end will move outward, causing the mixed material originally accumulated on the movable screen 10 to be pushed, causing most of the mixed material to be scraped out from both sides of the screening box 11, thereby discharging a large amount of accumulated mixed material.

The end of the folding rod 173 away from the vertical slide plate 172 is fixedly connected to a slope material 174, and the bottom of the slope material 174 is respectively squeezed and adapted with the first slope block 105 and the second slope block 107, and then The vertical slide plate 172 is pushed inward, so that the folding rod 173 fixedly connected to the top of the vertical slide plate 172 will move inward with the inclined surface material 174 until the inclined surface material 174 squeezes the No. 1 inclined surface block 105 and the No. 2 inclined surface block 107 in turn, and the squeezed No. 1 inclined surface block 105 and the No. 2 inclined surface block 107 will respectively move downward with the No. 1 dust pressing plate 103 and the No. 2 dust pressing plate 104 connected to the bottom thereof, while the No. 1 dust pressing plate 103 and the No. 2 dust pressing plate 104 are respectively fixedly connected to the No. 1 dust pressing plate 103 and the No. 2 dust pressing plate 107. The first and second anti-leakage bullet tubes 106 and 108 on the plate 104 will be stretched, and the first and second anti-leakage bullet tubes 106 and 108 will play a role in preventing leakage. At the same time, the downward movement of the first and second dust suppressing plates 103 and 104 will compress the internal space of the screening box 11 to prevent the mixed material from flying all over the sky during the accumulation or discharge of the mixed material. The side of the fixed track 175 away from the vertical slide plate 172 is fixedly connected with an electric telescopic rod 176, and the electric telescopic rod 176 An inclined scraper 177 is fixedly connected to one end away from the fixed rail 175, and a discharge plate 170 is slidably adapted on the outer side of the inclined scraper 177.

[0041] An airflow separation and aluminum removal system after the initial processing of black powder, the airflow separation and aluminum removal system is composed of an induction detector and a fan 5; The induction detector includes an infrared sensor 7 and a control terminal 6, and the infrared sensor 7 and the control terminal 6 are connected via a signal; The infrared sensor 7 is used to collect data on the appearance of the mixed material inside the circulation tube 4; The control terminal 6 consists of three parts: a receiving unit, a processing unit and an output unit; Receiving unit: receiving the information of the mixed material detected by infrared sensing; Processing unit: analyze and process the mixture information; Output unit: outputs the signal transmitted by the processing unit.

[0042] When the present invention is used: first, pour the mixture of black powder and aluminum powder from the feed pipe 131, then the mixture will slide down due to gravity and hit the four-point rotating plate 133 and the equalizing plate 135, so that the four-point rotating plate 133 rotates clockwise through the rotating shaft 132, and the equalizing plate 135 connected to the four-point rotating plate 133 through the internal spring 134 will also rotate accordingly, and in the process of rotating to the bottom, the internal spring 134 will be stretched, and the equalizing plate 135 will extend from the four-point rotating plate 133, so that the elastic sheet 136 fixedly connected to the other end thereof will rub the top of the movable screen 10. Then the mixed material transported in batches will move downward along the movable screen 10, and the vibration motor 12 will be started again, so that the entire screening box 11 will vibrate, and then the aluminum with larger particles will remain on the movable screen 10, while the black powder with smaller particles will enter the circulation pipe 4 through the movable screen 10.

[0043] If the mixed powder accumulates or gets clogged at the tail of the movable screen 10, a large amount of mixed powder will stay on the reset plate 100, and then the reset plate 100 that is squeezed will deflect downward through the connecting shaft inside the support 109, and the toughness sheet 1001 will be compressed until the accumulated part of the mixed material is discharged downward. When too much material is accumulated, the electric telescopic rod 176 is started, so that the inclined scraper 177 connected to the output end thereof will move outward, so that the mixed material originally accumulated on the movable screen 10 will be pushed, so that most of the mixed material will be scraped out from both sides of the screening box 11. Then, the vertical slide plate 172 is pushed inward, so that the folding rod 173 fixedly connected to the top of the vertical slide plate 172 will move inward with the inclined surface material 174 until the inclined surface material 174 squeezes the No. 1 inclined surface block 105 and the No. 2 inclined surface block 107 in turn, and the squeezed No. 1 inclined surface block 105 and No. 2 inclined surface block 107 will respectively move downward with the No. 1 dust suppressing plate 103 and No. 2 dust suppressing plate 104 connected to the bottom thereof, and at the same time, the No. 1 anti-leakage bullet tube 106 and the No. 2 anti-leakage bullet tube 108 respectively fixedly connected to the No. 1 dust suppressing plate 103 and the No. 2 dust suppressing plate 104 will be stretched.

At this time, the infrared sensor 7 will receive the signal and transmit it to the control terminal 6. The control terminal 6 will then judge the signal and finally instruct the fan 5 to start. Then the fan 5 will generate wind and blow the mixed powder into the cyclone separation tank 31.
