Description

Technical Field

[0001] This invention belongs to the field of aluminum paste recycling technology, specifically relating to a processing system and process for recycling waste aluminum paste particles. Background Technology

[0002] Currently, the aluminum paste used in the autoclaved aerated concrete industry forms granules after its shelf life. These granules cannot disperse in water and cannot be reused. They need to be reprocessed and crushed to disperse in water for reuse. However, existing technologies for crushing and recycling aluminum paste granules are limited to adding them back into a ball mill for grinding. The grinding and crushing process has not yet been integrated with subsequent screening, grading, mixing, and kneading processes to form a continuous production system. Operators need to feed the material multiple times, resulting in high labor costs and low output.

[0003] In addition, in traditional processes, the structure for quantitatively adding aluminum powder to the horizontal kneader includes a powder weighing scale and a screw feeder. The screw feeder generally conveys a large amount of powder. Even if the PLC control cabinet controls the screw feeder to stop conveying in a timely manner based on the weighing data of the powder weighing scale, the actual amount of aluminum powder conveyed will still exceed the set amount, resulting in an inaccurate ratio of aluminum powder to solvent. Therefore, in the redesigned production line, the structure needs to be further improved to achieve more accurate control of the amount of aluminum powder conveyed to the horizontal kneader and strictly control the ratio of aluminum powder to solvent to improve the quality of the final product. Summary of the Invention

[0004] The purpose of this invention is to provide a processing system and process for recycling waste aluminum paste particles in order to solve the above-mentioned problems, thereby addressing the shortcomings of the prior art.

[0005] The present invention achieves the above objectives through the following technical solutions: A processing system for recycling waste aluminum paste particles includes a feeding hopper, a double-roll crusher, a vibrating screen, and a cyclone separator connected in sequence, a coarse powder processing line and a fine powder processing line connected to the cyclone separator, and a circulation pipeline between the vibrating screen and the feeding hopper for conveying the sheet-like aluminum blocks screened by the vibrating screen back to the feeding hopper. Both coarse and fine powder processing lines include a transfer tank, a powder weighing scale, and a horizontal kneader arranged in sequence, and each of the two horizontal kneaders is equipped with a solvent feed pipe. A weighing accuracy adjustment component for adjusting the amount of powder inside the powder weighing scale is provided between the transfer tank and the powder weighing scale.

[0006] As a further optimization of the present invention, the two output ends of the powder weighing scales are equipped with a powder mixing production line, which includes a horizontal kneader and a solvent feed pipe. A switch valve is provided on each of the two output pipes of the powder weighing scales.

[0007] As a further optimization of the present invention, the processing system also includes a PLC control cabinet. The solid materials in the processing system are all conveyed by a screw feeder. The screw feeder, the double roll crusher, the vibrating screen, the cyclone separator, and the horizontal kneader one and the horizontal kneader two are all electrically connected to frequency converters controlled by the PLC control cabinet.

[0008] As a further optimization of the present invention, the solid material conveying is a closed conveying system, that is, all solid material inlets and outlets of the structure are equipped with dust removal components. Specifically, the dust removal components include a protective cover, a dust collection pipe connected to the protective cover, and a dust collection bag located at the output end of the dust collection pipe.

[0009] As a further optimization of the present invention, the weighing accuracy adjustment component includes a horizontal moving structure, a vertical moving structure, a material digging and feeding structure, a detector four located on the inner wall of the powder weighing scale, a temporary storage box located on one side of the powder weighing scale, a material conveying pipe connecting the temporary storage box and the powder weighing scale, and a switch valve two located on the material conveying pipe.

[0010] As a further optimization of the present invention, the material feeding structure includes a fixed seat on one side of the slider, a bucket rotatably connected to the fixed seat, and a rotation adjustment component that drives the bucket to rotate relative to the fixed seat. The inner wall of the bucket away from the fixed seat is a sloping surface. The fixed seat has a groove inside for the bucket to rotate inside and for limiting its upper and lower rotation limits.

[0011] As a further optimization of the present invention, the rotation adjustment component includes detector one and detector two respectively disposed on the upper and lower walls of the tank, at least two detector three disposed along the inner wall of the tank along the rotation path of the container, a hanging ring disposed on the upper edge of the inclined side of the container, a mounting base disposed at the bottom of the slider one, a reel rotatably connected to the mounting base, a rope disposed between the hanging ring and the reel, and a rotation drive component for driving the reel to rotate and winding the rope.

[0012] The present invention also provides a processing technology for recycling waste aluminum paste particles using the processing system described above, comprising the following steps: Step 1: After aluminum paste granules are fed into the hopper, they are conveyed to the roller crusher for crushing. After crushing, an aluminum powder mixture is obtained and conveyed to a vibrating screen for screening. The flaky aluminum blocks are then conveyed back to the hopper through the circulation pipeline. The aluminum powder that meets the crushing requirements is conveyed to the cyclone separator for separation into coarse powder and fine powder. The coarse powder and fine powder are then conveyed to the coarse powder and fine powder processing lines, respectively. Step 2: The coarse and fine powders conveyed to the coarse and fine powder processing lines are stored in their respective transfer tanks. After being weighed and measured by the corresponding powder weighing scales, they are conveyed to the corresponding horizontal kneader 1 / horizontal kneader 2. Solvents are added for kneading and processing to obtain the corresponding products.

[0013] As a further optimization of the present invention, during the weighing and metering process of the powder weighing scale, the powder accuracy is also adjusted by a weighing accuracy adjustment component, specifically as follows: When the excess powder in the powder weighing scale exceeds the single capacity of the hopper, the excess powder in the powder weighing scale is transferred to the temporary storage box (i.e., line one). When the excess amount of powder in the powder weighing scale is less than the single capacity of the hopper, the excess amount of powder is divided into N+1 levels according to the number N of detector three, and the excess powder in the powder weighing scale is poured into the powder weighing scale according to the level (i.e., line two). Route 1: After using the hopper to collect the powder from inside the powder weighing scale, move it above the temporary storage box and pour all the powder from the hopper into the temporary storage box; Route 2: After using the hopper to collect the powder from the powder weighing scale, keep it above the powder weighing scale. Detector 3 or detector 1, which corresponds to the excess amount of powder, detects the rotation position of the hopper to pour the powder from the hopper into the powder weighing scale. Then move it above the temporary storage box to pour all the remaining powder from the hopper into the temporary storage box.

[0014] The beneficial effects of this invention are as follows: In this invention, by connecting the grinding and crushing process with the subsequent screening and grading process and the mixing and kneading process to form a continuous production system, continuous production of aluminum paste particles can be achieved, which improves production efficiency, reduces the difficulty and workload of personnel operation, and at the same time, screening and grading coarse powder and fine powder can produce products of different specifications, thus diversifying the products. The solid material conveying in this invention is a closed conveying system, which can absorb dust through dust collector bags, ensuring air permeability while preventing dust from being stirred up. The present invention provides a weighing accuracy adjustment component between the transfer tank and the powder weighing scale. This weighing accuracy adjustment component can more accurately control the amount of aluminum powder delivered to the horizontal kneader one / horizontal kneader two, and more precisely control the ratio of aluminum powder to solvent, thereby improving product quality.

Both coarse and fine powder processing lines include a transfer tank 5, a powder weighing scale 6, and a horizontal kneader 71 arranged in sequence, with solvent feed pipes installed on each of the two horizontal kneaders 71.

[0026] It should be noted that in this embodiment, the roller gap between the two rollers of the roller crusher 2 is elastically adjustable, and the minimum elastically adjustable roller gap range is 0-5mm, preferably 0.1mm.

[0027] Preferably, the processing system also includes a PLC control cabinet 12. The solid materials in the processing system are all conveyed by a screw feeder. The screw feeder, the double roll crusher 2, the vibrating screen 3, the cyclone separator 4, and the horizontal kneader 1 71 and the horizontal kneader 2 72 are all electrically connected to frequency converters controlled by the PLC control cabinet 12.

[0028] Preferably, in this embodiment, the solid material conveying is all closed conveying, that is, all solid material inlets and outlets are equipped with dust removal components (generally composed of a cover and a dust removal bag).

[0029] It should be noted that in this embodiment, the frequency converter, screw feeder, double roll crusher 2, vibrating screen 3, cyclone separator 4, powder weighing scale 6, and horizontal kneader 71 are all controlled and operated through PLC control cabinet 12.

[0030] A processing technology for recycling waste aluminum paste particles using the above-mentioned processing system includes the following steps: Step 1: Aluminum paste granules (diameter 1-5mm) are fed into hopper 1 and then conveyed to roller crusher 2 for crushing. After crushing, an aluminum powder mixture is obtained and conveyed to vibrating screen 3 for vibration screening. The flaky aluminum blocks are then conveyed back to hopper 1 through circulation pipeline 1. The aluminum powder that meets the crushing requirements is conveyed to cyclone separator 4 for cyclone separation to obtain coarse powder (coarse powder is output from the bottom of cyclone separator 4) and fine powder (fine powder is output from the top of cyclone separator 4). The coarse powder and fine powder are respectively conveyed to the coarse powder and fine powder processing production lines. Step 2: The coarse powder and fine powder from the coarse powder processing line and fine powder processing line are stored in their respective transfer tanks 5. After being weighed and measured by the corresponding powder weighing scales 6, they are transported to the corresponding horizontal kneader 71. The solvents used for the production of the corresponding products are then supplied into the horizontal kneader 71 (nitrogen environment, oxygen content 3%) for kneading and processing to obtain the corresponding products (coarse powder product A, fine powder product B).

[0031] Example 2 like Figure 2 As shown, a processing system for recycling waste aluminum paste granules is presented in this embodiment, which is a further improvement on Embodiment 1, as detailed below: The output ends of the two powder weighing scales 6 in the coarse and fine powder processing production line are equipped with a mixed powder processing production line. The mixed powder processing production line includes a horizontal kneader 2 72 and a solvent feed pipe 2. Each of the two output pipes of the two powder weighing scales 6 is equipped with a switch valve 1.

[0032] It should be noted that in this embodiment, the switching valves on the two output pipes of the two powder weighing scales 6 (when conveying powder to the horizontal kneader A, the switching valve on the pipe connected to the output of the powder weighing scale 6 and the horizontal kneader A is opened accordingly; when conveying powder to the horizontal kneader B, the switching valve on the pipe connected to the output of the powder weighing scale 6 and the horizontal kneader B is opened accordingly; when conveying powder to the horizontal kneader C, the switching valves on the pipes connected to the output of the two powder weighing scales 6 and the horizontal kneader C are opened accordingly), frequency converter, screw feeder, double roll crusher 2, vibrating screen 3, cyclone separator 4, powder weighing scale 6, horizontal kneader 1 71, and horizontal kneader 2 72 are all controlled and operated through PLC control cabinet 12.

[0033] A processing technology for recycling waste aluminum paste particles using the above-mentioned processing system includes the following steps: Step 1: After aluminum paste granules are fed into the feeding hopper 1, they are conveyed to the double roll crusher 2 for crushing. After crushing, an aluminum powder mixture is obtained, which is then conveyed to the vibrating screen 3 for vibration screening. The flaky aluminum blocks are then conveyed back to the feeding hopper 1 through the circulation pipeline. The aluminum powder that meets the crushing requirements is then conveyed to the cyclone separator 4 for cyclone separation to obtain coarse powder (coarse powder is output from the bottom of the cyclone separator 4) and fine powder (fine powder is output from the top of the cyclone separator 4). The coarse powder and fine powder are then conveyed to the coarse powder and fine powder processing production lines, respectively. Step 2: The coarse powder and fine powder conveyed to the coarse powder and fine powder processing production lines are stored in their respective transfer tanks 5. After being weighed and measured by the corresponding powder weighing scales 6, they are conveyed to the horizontal kneader 1 71 or the horizontal kneader 2 72. The solvents used for the production of the corresponding products are then conveyed into the horizontal kneader 1 71 or the horizontal kneader 2 72 for kneading and processing to obtain the corresponding products (coarse powder product A, fine powder product B, and mixed powder product C).

[0034] In order to solve the problem that the PLC control cabinet 12 can control the screw feeder to stop conveying in a timely manner based on the weighing data of the powder metering scale, but the actual conveyed aluminum powder will exceed the set amount of aluminum powder, resulting in an inaccurate ratio of aluminum powder to solvent, this application proposes the following technical solution in embodiment 3 based on embodiments 1-2.

[0035] Example 3 like Figure 1-8 As shown, a processing system for recycling waste aluminum paste granules is presented in this embodiment, which is a further improvement on Embodiment 2, as detailed below: A weighing accuracy adjustment component for adjusting the amount of powder inside the powder weighing scale 6 is provided between the transfer tank 5 and the powder weighing scale 6.

[0039] Preferably, the material feeding structure includes a fixed seat 95 located on one side of the slider 94, a hopper 96 rotatably connected to the fixed seat 95, and a rotation adjustment component 97 that drives the hopper 96 to rotate relative to the fixed seat 95. The inner wall of the hopper 96 away from the fixed seat 95 is a sloping surface. The fixed seat 95 has a groove inside which the hopper 96 rotates and the upper and lower limits of its rotation are limited.

[0040] Preferably, the rotation adjustment component 97 includes detector 1 971 and detector 2 972 respectively disposed on the upper and lower walls of the tank, at least two detector 3 978 disposed along the inner wall of the tank along the rotation path of the container 96, a hanging ring 973 disposed on the upper edge of the inclined side of the container 96, a mounting base 974 disposed at the bottom of the slider 1 92, a reel 975 rotatably connected to the mounting base 974, a rope 977 disposed between the hanging ring 973 and the reel 975, and a rotation drive component 976 for driving the reel 975 to rotate and winding the rope 977.

[0041] It should be noted that in this embodiment, detector 1 971, detector 2 972, and detector 3 978 are all pressure sensors, specifically XPM4 pressure sensors.

[0042] It should be noted that in this embodiment, the switching valves on the two output pipes of the two powder weighing scales 6 (when conveying powder to the horizontal kneader A, the switching valve on the pipe connected to the output of the powder weighing scale 6 and the horizontal kneader A is opened accordingly; when conveying powder to the horizontal kneader B, the switching valve on the pipe connected to the output of the powder weighing scale 6 and the horizontal kneader B is opened accordingly; when conveying powder to the horizontal kneader C, the switching valves on the pipes connected to the output of the two powder weighing scales 6 and the horizontal kneader C are opened accordingly), frequency converter, screw feeder, double roll crusher 2, vibrating screen 3, cyclone separator 4, powder weighing scale 6, horizontal kneader 1 71, and horizontal kneader 2 72 are all controlled and operated through PLC control cabinet 12, and the telescopic component 1, telescopic component 2, and rotary drive component 976 are also controlled and operated through PLC control cabinet 12.

[0043] A processing technology for recycling waste aluminum paste particles using the above-mentioned processing system includes the following steps: Step 1: After aluminum paste granules are fed into the feeding hopper 1, they are conveyed to the double roll crusher 2 for crushing. After crushing, an aluminum powder mixture is obtained, which is then conveyed to the vibrating screen 3 for vibration screening. The flaky aluminum blocks are then conveyed back to the feeding hopper 1 through the circulation pipeline. The aluminum powder that meets the crushing requirements is then conveyed to the cyclone separator 4 for cyclone separation to obtain coarse powder (coarse powder is output from the bottom of the cyclone separator 4) and fine powder (fine powder is output from the top of the cyclone separator 4). The coarse powder and fine powder are then conveyed to the coarse powder and fine powder processing production lines, respectively. Step 2: The coarse and fine powders conveyed to the coarse and fine powder processing lines are stored in their respective transfer tanks 5. After being weighed and measured by the corresponding powder weighing scales 6, they are conveyed to the horizontal kneader 1 71 or the horizontal kneader 2 72. The solvents used for the production of the corresponding products are then conveyed into the horizontal kneader 1 71 or the horizontal kneader 2 72 for kneading processing to obtain the corresponding products (coarse powder product A, fine powder product B, and mixed powder product C). During the weighing process of the powder weighing scale 6, the powder accuracy is also adjusted through the weighing accuracy adjustment component, specifically as follows: When the excess amount of powder in the powder weighing scale 6 exceeds the single capacity of the hopper 96, the excess powder in the powder weighing scale 6 is transferred to the temporary storage box 10 (operation of line one). When the excess amount of powder in the powder weighing scale 6 is less than the single capacity of the hopper 96, the excess amount of powder is divided into N+1 levels according to the number N of the detector 3 978, and the excess powder in the powder weighing scale 6 is poured into the powder weighing scale 6 in stages (operation of line 2). Route 1: ① Release rope 977 to allow the container 96 to rotate to its lower rotation limit position under its own weight (i.e., stop releasing rope 977 when detector 971 detects pressure), and move the container 96 down into the powder inside the powder weighing scale 6 via the vertical moving structure; ② Rotate the container 96 to its upper rotation limit position by winding rope 977 (i.e., stop winding rope 977 when detector 972 detects pressure), thereby collecting the powder; ③ Move the container 96 up via the vertical moving structure, while keeping the winding rope 977 in place to keep the container 96 at its upper rotation limit position. After the vertical position is adjusted; ④ Move the container 96 horizontally via the horizontal moving structure. After the horizontal position is adjusted, release rope 977 to allow the container 96 to rotate to its lower rotation limit position under its own weight, emptying all the powder inside the container 96 into the temporary storage box 10; Route 2: Perform steps ①-③ consistent with Route 1; ④ Keep in place while releasing rope 977 to allow the container 96 to rotate under its own weight. Based on the excess powder level, classify the corresponding level and check the pressure detected by detector 3 978 or detector 1 971. Then stop releasing rope 977. Figure 8 As shown, the excess powder is classified into three levels from most to least: Level 3, Level 2, and Level 1. When the level is Level 3, the release of rope 977 stops when detector 1 971 detects pressure. When the level is Level 2, the release of rope 977 stops when detector 3 978, which is closer to detector 1 971, detects pressure. When the level is Level 1, the release of rope 977 stops when detector 3 978, which is closer to detector 2 972, detects pressure. ⑤ The rope 977 is wound up to level the container 96, and then the container 96 is moved horizontally by the lateral movement structure. After the lateral position is adjusted, the rope 977 is released so that the container 96 rotates to the lower limit position under its own weight, and all the powder inside the container 96 is poured into the temporary storage box 10.

[0044] The gloss of coarse powder product A, fine powder product B, and mixed powder product C from Examples 2 and 3 was tested according to ISO 2813. The results showed that, compared with coarse powder product A (51.3 Gs) from Example 2, the gloss of coarse powder product A (60.1 Gs) from Example 3 was increased by 17.2%; compared with fine powder product B (72.4 Gs) from Example 2, the gloss of fine powder product B (88.2 Gs) from Example 3 was increased by 21.8%; and compared with mixed powder product C (66.3 Gs) from Example 2, the gloss of mixed powder product C (79.4 Gs) from Example 3 was increased by 19.8%.

[0045] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
