[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention is provided with a heating screening structure, an angle adjustment mechanism, a vibration mechanism and an air selection structure. The inclination angle of the sieve plate is adjusted by the angle adjustment mechanism to control the flow speed and direction of the aluminum ash. The close cooperation between the sieve plate and the angle adjustment mechanism ensures the stability and reliability of the sieve plate during the inclination process. The vibration mechanism drives the sieve plate to reciprocate up and down in its inclined plane. The vibration action not only promotes the uniform distribution of the aluminum ash on the sieve plate, but also enhances the relative movement of the aluminum ash and the sieve plate, which is helpful to better separate the aluminum component in the aluminum slag from the aluminum ash, and drips into the receiving box through the mesh of the sieve plate, making the screening process more efficient and thorough. The air selection structure utilizes the negative pressure generated by the external air selection equipment to extract the useless aluminum ash raised on the sieve plate, prevents the aluminum ash from falling back onto the surface of the sieve plate, and makes the aluminum slag content in the aluminum ash subsequently put onto the sieve plate relatively stable, thereby achieving the goal of maintaining the processing efficiency and processing difficulty unchanged during the long-term processing of the aluminum slag.

[0023] 2. The present invention is provided with a bracket, a first rectangular frame and an angle adjustment component. The angle adjustment component can realize flexible adjustment of the inclination angle of the first rectangular frame and the sieve plate through the coordinated work of at least two linear pushers, so that the device can quickly adjust the inclination angle of the sieve plate according to the changes in the aluminum slag content in different batches of aluminum ash to optimize the screening effect. The sieve plate is tightly connected with the first rectangular frame and moves synchronously, ensuring the integrity and stability of the sieve plate when adjusting the inclination angle, thereby ensuring that the sieve plate can perform efficient and stable vibration screening along a fixed inclination angle under the drive of the vibration mechanism.

[0024] 3. The present invention is provided with a residual material collection structure and two residual material boxes, one of which receives newly added aluminum ash at a high position, and the other collects aluminum ash containing aluminum slag remaining after preliminary screening at a low position. The angle adjustment mechanism is not only used to adjust the inclination angle of the screen plate, but also responsible for replacing the height of the two residual material boxes, so that the two residual material boxes can take turns as containers for receiving and discharging aluminum ash. By organically combining the residual material collection structure, the opening and closing structure, the angle adjustment mechanism, the screen plate and the air selection structure and other components, an automated and cyclic aluminum ash screening and collection system is formed, thereby preventing the aluminum slag from being discharged with the screened aluminum ash.

DETAILED DESCRIPTION

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Reference Figures 1 to 14 As shown: A dust-free secondary aluminum ash processing device, characterized in that it includes a material receiving box 1, a heating and screening structure 2, an angle adjustment mechanism 3, a vibration mechanism 4 and a wind selection structure 5; the material receiving box 1 is horizontally arranged, and the upper end of the material receiving box 1 is open; the heating and screening structure 2 is arranged above the material receiving box 1, and the heating and screening structure 2 includes a sieve plate 21 and a dust cover 22, the projection of the sieve plate 21 in the vertical direction is completely in the material receiving box 1, and a mesh for passing aluminum liquid is opened on the sieve plate 21, and a plurality of heating rods 23 are inserted in the sieve plate at equal intervals. The plate 21 is inside, and the heating rod 23 is perpendicular to the direction in which the aluminum ash moves on the sieve plate 21, and the dust cover 22 is arranged above the sieve plate 21; the angle adjustment mechanism 3 is arranged between the material receiving box 1 and the sieve plate 21, and the angle adjustment mechanism 3 is used to adjust the inclination angle of the sieve plate 21; the vibration mechanism 4 is arranged on one side of the sieve plate 21, and the vibration mechanism 4 is used to drive the sieve plate 21 to move reciprocally up and down in its inclined plane; the air selection structure 5 is arranged between the sieve plate 21 and the dust cover 22, and the air selection structure 5 is used to extract useless aluminum ash on the surface of the sieve plate 21.

[0042] A plurality of heating rods 23 inserted in the sieve plate 21 first heat the sieve plate 21, and the angle adjustment mechanism 3 adjusts the sieve plate 21 to an inclined state, and the aluminum ash moves along the inclined sieve plate 21 from the higher end to the lower end of the sieve plate 21, and the vibration mechanism 4 is started synchronously, and the vibration mechanism 4 drives the sieve plate 21 to reciprocate up and down in its inclined plane, which not only promotes the uniform distribution of the aluminum ash on the sieve plate 21, but also enhances the relative movement of the aluminum ash and the sieve plate 21, which helps the aluminum component in the aluminum slag to melt by heat and drip through the mesh. When it enters the receiving box 1, the role of the dust cover 22 is highlighted. The dust cover 22 effectively prevents aluminum ash from splashing due to vibration, thereby maintaining the cleanliness of the working environment. During this process, the air separation structure 5 continues to work, and uses the negative pressure generated by the external air separation equipment to extract the useless aluminum ash raised on the sieve plate 21, preventing the aluminum ash from falling back onto the surface of the sieve plate 21, so that the aluminum slag content in the aluminum ash subsequently added to the sieve plate 21 is relatively stable, thereby achieving the goal of maintaining the processing efficiency and processing difficulty unchanged during the long-term processing of aluminum slag.

[0043] Reference Figure 4 and Figure 5 As shown: the angle adjustment mechanism 3 includes a bracket 31, a first rectangular frame 32 and an angle adjustment component 33; the bracket 31 is arranged in the middle of the material receiving box 1, and vertical upward vertical plates 311 are arranged at both ends of the bracket 31; the first rectangular frame 32 is arranged between the two vertical plates 311, the sieve plate 21 is parallel to the first rectangular frame 32, and the sieve plate 21 is slidably connected to the first rectangular frame 32, and the two symmetrical side plates of the first rectangular frame 32 are higher than the upper surface of the sieve plate 21, which can prevent aluminum ash from overflowing during the treatment process, and rotating shafts 321 are arranged on both sides of the middle of the first rectangular frame 32, and the two rotating shafts 321 are respectively connected to the two vertical plates 311 through bearings; the angle adjustment component 33 is arranged on the vertical plate 311, and the angle adjustment component 33 is used to adjust the first rectangular frame 32 to rotate around the axis of the rotating shaft 321, and the angle adjustment component 33 includes at least two linear pushers 331, and the two ends of the linear pusher 331 are respectively axially connected to the end of the bracket 31 and the first rectangular frame 32.

[0044] The content of aluminum slag in different batches of aluminum ash may be different. When the inclination angle of the sieve plate 21 is fixed, if the aluminum ash with a higher aluminum slag content moves too fast along the sieve plate 21 at the inclination angle, the aluminum slag in the aluminum ash may not be completely separated after the aluminum ash passes through the sieve plate 21. If the aluminum ash with a lower aluminum slag content moves too slowly along the sieve plate 21 at the inclination angle, the processing speed of the aluminum ash will be affected. By setting the bracket 31, the first rectangular frame 32 and the angle adjustment component 33, when the device processes the aluminum ash, the angle adjustment component 33 adjusts the first rectangular frame 32 according to the content of aluminum slag in the aluminum ash. The angle adjustment component 33 includes at least a linear pusher 33. 1. When the inclination angle of the sieve plate 21 needs to be adjusted, the two linear pushers 331 work together to push one end of the first rectangular frame 32 up or down, while the other end drops or rises accordingly, so as to realize the flexible adjustment of the inclination angle of the first rectangular frame 32. The sieve plate 21 moves synchronously with the first rectangular frame 32. After the sieve plate 21 is adjusted to a suitable angle, the angle adjustment component 33 fixes the inclination angle of the first rectangular frame 32. When the vibration mechanism 4 drives the sieve plate 21 to vibrate, the sieve plate 21 vibrates up and down along the inclined first rectangular frame 32, thereby ensuring that the sieve plate 21 can be driven by the vibration mechanism 4 to perform efficient and stable vibration screening along the fixed inclination angle.

[0045] Reference Figure 4 , Figure 6 and Figure 7 As shown: the vibration mechanism 4 includes a sliding connection structure 41 and a synchronous vibration structure 42; the sliding connection structure 41 has at least two, and the two sliding connection structures 41 are symmetrically arranged on the side walls of the first rectangular frame 32, the sliding connection structure 41 includes a connecting block 411 and a first guide structure 412, one end of the connecting block 411 is connected to the screen plate 21, and the other end of the connecting block 411 extends out of the first rectangular frame 32, the first guide structure 412 includes a first guide cross bar 4121 and a first moving block 4122, both ends of the first guide cross bar 4121 are connected to the first rectangular frame 32, the first moving block 4122 is slidably arranged on the first guide cross bar 4121, and the first moving block 4122 is fixedly connected to the connecting block 411; the synchronous vibration structure 42 is arranged between the two sliding connection structures 41, and the synchronous vibration structure 42 includes a synchronous driving plate 421, and both ends of the synchronous driving plate 421 are respectively connected to the two first moving blocks 4122.

[0046] Through the two sliding connection structures 41, the sieve plate 21 can always remain parallel to the first rectangular frame 32, ensuring that when the first rectangular frame 32 adjusts the inclination angle according to demand, the angle can be accurately transmitted to the sieve plate 21, avoiding the problem of poor aluminum liquid flow or low screening efficiency caused by angle deviation during the screening process. When the screening operation needs to be started, the synchronous vibration structure 42 starts to work, and the synchronous driving plate 421 is used as the core component. The two ends of the synchronous driving plate 421 are respectively connected to the two first moving blocks 4122. The synchronous driving plate 421 reciprocates, and the two first moving blocks 4122 reciprocate synchronously along their respective first guide cross bars 4121. The synchronous movement ensures the stability and consistency of the screen plate 21 during the vibration process. Driven by the synchronous driving plate 421, the screen plate 21 reciprocates along the first guide cross bar 4121, so that the aluminum ash on the screen plate 21 is subjected to periodic screening. The vibration not only promotes the uniform distribution of the aluminum liquid, but also accelerates the process of the aluminum liquid flowing to the mesh, thereby improving the screening efficiency and screening accuracy.

[0047] Reference Figure 6 , Figure 8 and Fig. 9 As shown: the synchronous vibration structure 42 also includes a second guide structure 422 and a reciprocating drive structure 423; the second guide structure 422 includes a U-shaped plate 4221, a second guide cross bar 4222 and a second moving block 4223, the U-shaped plate 4221 is arranged on one side of the vertical plate 311, and the opening of the U-shaped plate 4221 is away from the vertical plate 311, the upper end of the U-shaped plate 4221 is fixedly connected to the rotating shaft 321, the second guide cross bar 4222 is arranged in parallel with the synchronous drive plate 421, and the two ends of the second guide cross bar 4222 are fixedly connected to the U-shaped plate 4221, and the second moving block 4223 is slidably arranged on The second guide cross bar 4222 is on the second moving block 4223, and the middle part of the synchronous drive plate 421 is connected; the reciprocating drive structure 423 is arranged on the U-shaped plate 4221, and the reciprocating drive structure 423 is used to drive the synchronous drive plate 421 to reciprocate along the second guide cross bar 4222. The reciprocating drive structure 423 includes a first rotation driver 4231, a first drive plate 4232 and a second drive plate 4233. The output shaft of the first rotation driver 4231 is connected to the first drive plate 4232, and the second drive plate 4233 connects the first drive plate 4232 and the synchronous drive plate 421.

[0048] Since the two sliding connection structures 41 will follow the movement of the first rectangular frame 32, the synchronous driving plate 421 needs to follow the synchronous tilt of the first rectangular frame 32. By setting the second guide structure 422 and the reciprocating driving structure 423, when the first rectangular frame 32 needs to adjust its tilt angle according to the screening demand, it will first be transmitted to the U-shaped plate 4221 fixedly connected thereto through the rotating shaft 321. Therefore, the U-shaped plate 4221 will rotate around the rotating shaft 321 as the first rectangular frame 32 tilts. The U-shaped plate 4221 is connected with the second guide cross bar 4222 and the second moving block 4223 to further drive the synchronous driving plate 421 to rotate synchronously. When the reciprocating motion of the sieve plate 21 needs to be started, When vibrating, the reciprocating drive structure 423 starts to work, and the first rotation driver 4231 acts as a power source to drive the first drive plate 4232 to rotate. The first drive plate 4232 forms a stable connection with the synchronous drive plate 421 through the second drive plate 4233. When the first drive plate 4232 rotates, the first drive plate 4232 applies periodic pulling force and thrust to the second drive plate 4233. The pulling force and thrust are transmitted to the synchronous drive plate 421 through the second drive plate 4233, driving the synchronous drive plate 421 to reciprocate along the second guide cross bar 4222, thereby ensuring that the synchronous drive plate 421 and the first rectangular frame 32 always maintain a consistent inclination angle.

[0049] Reference Figure 3 and Fig.10 As shown: the dust-free secondary aluminum ash processing device also includes a residual material collection structure 6, which has two residual material collection structures 6, which are respectively arranged at the two ends of the sieve plate 21, and the residual material collection structure 6 includes a residual material box 61, a cover plate 62 and an opening and closing structure 63; the upper end of the residual material box 61 is open, and the residual material box 61 is provided with an inlet and outlet port 611 on one side facing the middle of the sieve plate 21, and the lowest point of the inlet and outlet port 611 is flush with the upper surface of the sieve plate 21; the cover plate 62 is provided with a cover plate 63, and the cover plate 62 is provided with a cover plate 63; the upper end of the residual material box 61 is open, and the upper end of the residual material box 61 is provided with an inlet and outlet port 611. The lower end of ... provided with a cover plate 63, and the cover plate 62 is provided with a cover plate 63; the upper end of the residual material box 61 is provided with a cover plate 63; the upper end of the residual material box 61 is provided with a cover plate 63; the upper end of the residual material box 61 is provided with a cover plate 63; the upper end of the residual material box 61 is provided with a cover plate 63; the upper end of the residual material box 61 is provided with a cover plate 63; the upper end of the residual material box 61 is provided with a The plate 62 cover is arranged at the upper end of the residual material box 61; the opening and closing structure 63 is arranged at the inlet and outlet port 611, and the opening and closing structure 63 is used to open and close the inlet and outlet port 611. The inlet and outlet port 611 includes an opening and closing plate 631 and a linear drive 632. The opening and closing plate 631 is tightly attached to the side wall of the residual material box 61, and the linear drive 632 is arranged at the upper end of the opening and closing plate 631. The linear drive 632 is used to drive the opening and closing plate 631 to move up and down along the side wall of the residual material box 61.

[0050] When the aluminum ash moves along the sieve plate 21 to the lowest point of the sieve plate 21, the aluminum ash that has not been extracted by the air selection structure 5 may still contain aluminum slag. By setting up two residual material collection structures 6, the aluminum ash is first placed in the residual material box 61 at a higher position, and covered with a cover plate 62. The opening and closing structures 63 on the two residual material boxes 61 both open the inlet and outlet ports 611. As the sieve plate 21 starts to vibrate, the aluminum ash moves from a high position to a low position along the surface of the sieve plate 21. Before reaching the lowest point of the sieve plate 21, most of the aluminum ash will be screened by the air selection structure 5, but some aluminum ash containing aluminum slag cannot be extracted by the air selection structure 5. These aluminum ash The ash is collected in the lower residual material box 61. As the last aluminum ash on the screen plate 21 also enters the lower residual material box 61, the lower opening and closing structure 63 quickly closes the inlet and outlet 611 to ensure that the aluminum ash does not overflow. The angle adjustment mechanism 3 exchanges the heights of the two residual material boxes 61 and prepares to open their inlet and outlet 611 to receive a new batch of aluminum ash. The above process is repeated continuously to form a continuous aluminum ash screening and collection cycle. Each residual material box 61 takes turns as a container for receiving and discharging aluminum ash, ensuring the continuity and efficiency of the screening process, thereby preventing aluminum slag from being discharged with the screened aluminum ash.

[0052] When the aluminum ash passes through the air separation cover 51, the aluminum ash is lifted upward by the vibration of the sieve plate 21, and the circular conveyor belt 521 rotates. The lower conveying surface of the circular conveyor belt 521 is opposite to the direction in which the sieve plate 21 conveys the aluminum ash. The external air separation equipment works, and the lower conveying surface of the circular conveyor belt 521 generates suction on the aluminum ash. The T-shaped collecting plate 522 on the circular conveyor belt 521 captures the raised aluminum ash. The vertical plate of the T-shaped collecting plate 522 contacts the aluminum ash in the air during the movement and captures the aluminum ash. When the T-shaped collecting plate 522 changes from the lower conveying surface to the upper return surface, the aluminum ash on the vertical plate slides to On the horizontal plate, the horizontal plate can prevent aluminum ash from falling. After the annular conveyor belt 521 transfers the aluminum ash captured by the T-shaped collecting plate 522 to the upper return surface, the aluminum ash falls onto the upper return surface of the annular conveyor belt 521, and the external air separation equipment extracts the aluminum ash on the upper return surface. When the inclination direction of the sieve plate 21 changes, the conveying direction of the lower conveying surface of the annular conveyor belt 521 also changes. The T-shaped collecting plate 522 can still capture the raised aluminum ash and transfer it to the upper end of the annular conveyor belt 521, so that the air separation structure 5 can change with the adjustment of the sieve plate 21, thereby maintaining the air separation effect of the air separation structure 5 on the aluminum ash.

[0053] Reference Fig.11 and Fig.13 As shown: the air selection structure 5 also includes a sliding structure 53, which has two sliding structures 53. The two sliding structures 53 are respectively arranged at the two ends of the air selection cover 51. The sliding structure 53 is used to assist the air selection structure 5 to slide along with the inclination of the sieve plate 21. The sliding structure 53 includes a guide slide bar 531 and a third slide bar 532. The two ends of the guide slide bar 531 are respectively connected to the two ends of the first rectangular frame 32. The third slide bar 532 is slidably arranged on the guide slide bar 531, and the third slide bar 532 is connected to the air selection cover 51.

[0054] Since the heights of the two ends of the sieve plate 21 are constantly adjusted, if the air selection structure 5 is at a higher position of the sieve plate 21, and the aluminum ash at a higher position of the sieve plate 21 contains more aluminum slag and is thicker, it is not conducive to the air selection structure 5 to extract the aluminum ash. By setting two sliding structures 53, when the sieve plate 21 drives the air selection structure 5 to move to a higher position, the air selection structure 5 relies on its own gravity to drive the third slider 532 to move downward along the guide slide rod 531, so that the air selection structure 5 is always at a lower position than the sieve plate 21, and the aluminum ash at the lower position of the sieve plate 21 is thinner and more easily lifted by vibration, thereby more effectively capturing and lifting the aluminum ash and improving the air selection efficiency.

[0055] Reference Fig.11 and Fig.13As shown: the air selection structure 5 also includes a buffer component 54, which has two buffer components 54. The two buffer components 54 are respectively arranged on the two sliding structures 53. The buffer component 54 includes two buffer springs 541, and the two buffer springs 541 are respectively mounted on the two ends of the guide slide rod 531.

[0056] If the inclination angle of the sieve plate 21 is large, the moving speed of the air selection structure 5 along the guide slide bar 531 will be too fast. By setting a buffer component 54, two buffer springs 541 are respectively set at the two ends of the guide slide bar 531. When the air selection structure 5 slides toward either end of the guide slide bar 531, the air selection structure 5 with a faster moving speed will first abut against the buffer spring 541, and the buffer spring 541 will be gradually compressed. In this process, the resistance component applied by the buffer spring 541 to the air selection structure 5 increases, causing the air selection structure 5 to gradually stop moving, thereby avoiding hard contact between the air selection structure 5 and the end of the guide slide bar 531, thereby improving the stability and reliability of the air selection structure 5.

[0057] Reference Figure 3 and Fig.14 As shown: the dust-free secondary aluminum ash processing device also includes an anti-blocking structure 7, which is arranged at the lower end of the sieve plate 21. The anti-blocking structure 7 is used to remove the aluminum ash solidified on the sieve plate 21. The anti-blocking structure 7 includes a second rectangular frame 71 and a plurality of scrapers 72. The second rectangular frame 71 is connected to the first rectangular frame 32. The plurality of scrapers 72 are equidistantly arranged on the second rectangular frame 71. The upper end of the scraper 72 abuts against the lower end of the sieve plate 21.

[0058] When the aluminum liquid flows from the mesh on the sieve plate 21 to the receiving box 1, the aluminum liquid may cool and solidify at the outlet of the mesh. As time goes by, the mesh may be blocked. By setting the anti-blocking structure 7, the positions of several scrapers 72 are fixed relative to the first rectangular frame 32. During the reciprocating vibration of the sieve plate 21, the sieve plate 21 and the several scrapers 72 move relative to each other. The scrapers 72 keep in contact with the bottom of the sieve plate 21, so that the solid aluminum solidified at the bottom of the sieve plate 21 is scraped off by the scrapers 72, thereby preventing the mesh of the sieve plate 21 from being blocked by the solidified aluminum.

[0059] A method for treating a dust-free secondary aluminum ash treatment device comprises the following steps:

[0060] S1, the staff first puts the aluminum ash into a residual material box 61 at one end of the screen plate 21 and covers it with a cover plate 62;

[0061] S2, the angle adjustment mechanism 3 lifts the residual material box 61 containing aluminum ash upward, and the empty residual material box 61 moves downward, at which time the screen plate 21 is in an inclined state;

[0062] S3, the vibration mechanism 4 drives the sieve plate 21 to vibrate along the inclined surface, the opening and closing structures 63 on the two residual material boxes 61 both open the inlet and outlet ports 611, and the aluminum ash slides out of the residual material boxes 61 and moves along with the vibrating sieve plate 21;

[0063] S4, the sieve plate 21 heats the aluminum ash on its surface, and the aluminum slag in the aluminum ash passes through the sieve plate 21 downward and falls into the receiving box 1, and the remaining aluminum ash is sucked away by the air selection structure 5;

[0064] S5, the aluminum ash that is not sucked away by the air separation structure 5 enters the empty residual material box 61. After the aluminum ash in the residual material box 61 located at a higher position is completely discharged, the angle adjustment mechanism 3 swaps the heights of the two residual material boxes 61, the sieve plate 21 tilts in the opposite direction, and the sieve plate 21 is vibrated again to process the aluminum ash.

[0065] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
