Description

Technical Field

[0001] The present invention belongs to the technical field of industrial silicon waste residue collection and treatment. More specifically, it particularly relates to an efficient collection and treatment device for industrial silicon production waste residue and a treatment method thereof. Background Art

[0002] A large amount of waste residue is generated during the production of industrial silicon. If these waste residues are not properly treated, they will not only occupy a large amount of land resources, but may also cause pollution to soil, water bodies and the air. With the enhancement of environmental protection awareness and the promotion of the concept of resource recycling and utilization, it has become increasingly important to efficiently collect and treat industrial silicon production waste residue. The following devices and structures are usually required for the collection and treatment of industrial silicon production waste residue:

[0003] 1. Collection device: Responsible for collecting the waste residue generated during the production process. Common ones include filter type, box type and dust suction type collection devices. Some can effectively collect the impurities in the waste residue and prevent dust from escaping.

[0004] 2. Conveying device: Transfers the collected waste residue to the treatment equipment. The screw conveyor is widely used due to its stable conveying and good sealing performance. Some can also achieve linear reciprocating movement to improve the uniformity of feeding.

[0005] 3. Crushing device: Crushes the waste residue for subsequent processing and utilization. Jaw crushers, cone crushers, etc. can crush large pieces of waste residue into smaller particles.

[0006] 4. Screening device: Classifies the crushed waste residue through a sieve mesh. Multi-stage screening can achieve more accurate particle size division. Common ones include fixed sieves and vibrating sieves, etc.

[0007] At present, in order to effectively collect and treat industrial silicon production waste residue, enterprises have adopted a variety of equipment and methods. Some enterprises adopt integrated collection and treatment equipment, integrating functions such as collection, conveying, and crushing, reducing the floor area of the equipment; some enterprises introduce an automated control system to achieve real-time monitoring and precise control of the waste residue collection and treatment process, improving production efficiency.

[0008] However, the above-mentioned embodiments still have the following problems. During the conveying process, some conveying devices cannot flexibly adapt to complex production layouts, and waste residues are easily blocked during the conveying process, affecting production continuity. In the crushing and screening processes, the coordination between devices is poor, resulting in low processing efficiency, and the accuracy of some screening devices is insufficient, making it difficult to meet the strict requirements for the particle size of waste residues. In response to this problem, this application proposes a solution and designs an efficient collection and treatment device for waste residues in industrial silicon production. This device uses a flexibly movable conveying mechanism to ensure uniformity during the feeding process, and a spiral structure is arranged in the conveying pipeline to prevent waste residues from being blocked. During the crushing and screening stages, crushing and screening are synchronized to enhance coordination. At the same time, a multi-stage screening design is adopted, combined with a swinging screen mesh, to improve screening accuracy. This device can optimize the conveying path, enhance the coordination in the crushing and screening processes, and achieve efficient collection and treatment of waste residues in industrial silicon production.

The upper surfaces of both sieves are fixedly connected with two baffle plates.

[0014] A processing method for an industrial silicon production waste residue high-efficiency collection and treatment device. The processing method of this device includes the following steps:

[0015] S1: Through a flexibly adjustable conveying mechanism, the collected waste residue is conveyed according to the production layout. During the conveying process, the spiral rod in the material conveying cavity is used for material conveying to prevent the waste residue from being blocked and ensure the continuity of conveying.

[0016] S2: Connect the crushing equipment and the screening equipment to the same motor. With the synchronous control of the servo motor 1, the coordinated operation of the two is realized. Driven by the servo motor 1, the two crushing rollers start to work, crushing the large waste residue into smaller particles to prepare for subsequent screening.

[0017] S3: When the crushing equipment starts to work, the screening equipment immediately responds to screen the crushed waste residue in a timely manner, reducing the intermediate waiting time and greatly improving the processing efficiency.

[0018] S4: The screening device adopts a multi-stage screening design. Screens with different screen hole sizes are arranged in sequence in the screening device. Through step-by-step screening, the refined grading of the waste residue is realized to meet the strict requirements of different users for the particle size of the waste residue. At the same time, the oscillating screen design is adopted, and the push rod is used to drive the sieve to swing up and down to effectively prevent the screen holes from being blocked and improve the screening accuracy.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, the linear reciprocating motion of the feeding chamber is realized by the forward and reverse rotation of the servo motor 2. The reciprocating movement of the feeding chamber can feed materials at different positions of the crushing box to avoid concentrated accumulation of waste slag, thereby reducing the blockage caused by excessive local accumulation. In addition, the waste slag can be evenly distributed in different areas of the two crushing rollers through movement, so that the crushing rollers can play their full role and avoid local idling or insufficient crushing. This can improve the overall crushing efficiency of the crushing box and process more waste slag in the same time.

[0021] In the present invention, the two push rods are designed to be elliptical and fit with the lower surfaces of the two screens. The two screens are rotatably connected to the two fixed bars. As the two push rods rotate, the screens fit with them are pushed up and down by the ellipse. The up and down swinging screens can cause the waste residue to jump and roll on the screen surface, increasing the contact opportunity between the waste residue particles and the screen holes after crushing, making it easier for the waste residue particles smaller than the screen holes to pass through the screen, thereby improving the screening efficiency, reducing the residence time of the waste residue on the screen surface, and being able to process more waste residue.

[0022] In the present invention, when the screen is swinging, the collision and friction between the waste particles and between the particles and the screen are intensified, which can effectively prevent the waste particles from accumulating and clogging at the screen holes. For sticky materials or waste that is easy to agglomerate, this swinging method can destroy the agglomerates of the waste, disperse the waste, and better screen it.

[0023] In the present invention, the two sieve holes have different sizes to achieve graded screening treatment, and the waste residue is gradually screened, so that the waste residue can be more accurately graded according to different particle size ranges. Compared with single-stage screening, multi-stage screening can more strictly control each particle size interval, reducing the problem of uneven size of screened particles caused by a single sieve hole size. After multi-stage screening, the waste residue particles of each particle size grade are more concentrated, which is convenient for subsequent recycling.

[0024] In the present invention, the waste residue is crushed and screened at the same time. The two are carried out simultaneously, which can realize the continuity of waste residue treatment. The waste residue enters the screening link immediately after being crushed, without the need for intermediate pauses or transfer processes, which greatly shortens the entire waste residue treatment time and improves production efficiency. The connection between the two processes will be closer, which is conducive to optimizing the production process.

[0025] In the present invention, pressure is generated on the surface of the synchronous belt, so that the synchronous belt is always in a suitable tension state, avoiding slipping caused by loosening of the synchronous belt, thereby ensuring the synchronization and stability of the operation of the crushing and screening mechanisms, and improving the efficiency and quality of waste slag treatment. The appropriate tensioning force can make the synchronous belt evenly stressed and reduce local wear and fatigue. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following further describes in detail the implementation manners of the present invention in conjunction with the attached drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0036] Please refer to Figure 1 - Figure 8, the present invention provides a high - efficiency collection and treatment device for industrial silicon production waste residue, including a frame 1. A crushing box 2 is fixedly connected to the upper surface of the frame 1. Above the crushing box 2, there is a feeding chamber 3 for feeding. A screw rod 21 is rotatably connected in the feeding chamber 3. Two crushing rollers 20 are rotatably connected in the crushing box 2. At the right end of the connecting shafts of the two crushing rollers 20, right - angled gears 11 are fixedly connected. On the right surfaces of the two right - angled gears 11, connecting rods two 16 are fixedly connected. A synchronous belt 12 is arranged on the right side of the two right - angled gears 11. A group of synchronous gears 17 are arranged inside the synchronous belt 12. On the left surfaces of the two synchronous gears 17 located below in the group of synchronous gears 17, push rods 13 are fixedly connected. Two fixing blocks 14 are fixedly connected to the upper surface of the crushing box 2. A lead screw one 19 is rotatably connected between the two fixing blocks 14. Two fixing strips 9 are fixedly connected inside the frame 1. On the upper surfaces of the two fixing strips 9, sieves 10 for filtering waste residue are rotatably connected. The two push rods 13 are respectively in contact with the two sieves 10. A fixing plate 8 is fixedly connected to the right end of the frame 1. A connecting rod one 7 is fixedly connected to the right surface of the fixing plate 8. A connecting frame 28 is fixedly connected to the rear surface of the connecting rod one 7. A lead screw two 27 is rotatably connected inside the connecting frame 28. A connecting strip 23 is arranged on the right side of the connecting rod one 7. An extrusion block 24 is fixedly connected to the right end of the connecting strip 23. A servo - motor three 22 is fixedly installed on the surface of the feeding chamber 3. The output shaft of the servo - motor three 22 is fixedly connected to the screw rod 21. During use, the waste residue is put into the feeding port 4. The waste residue put into the feeding port 4 will fall into the feeding chamber 3. By starting the servo - motor three 22, its output shaft will drive the fixed screw rod 21 to rotate. When the screw rod 21 rotates, it can stably convey the waste. Whether it is block - shaped or granular waste residue, it can be smoothly conveyed into the crushing box 2 by the push of the screw rod 21. At this time, by starting the servo - motor one 6, its output shaft will drive the fixed connecting rod two 16 to rotate. During the rotation of the connecting rod two 16, it will drive the fixed right - angled gear 11 to rotate. The rotation of the right - angled gear 11 will drive the other right - angled gear 11 meshing with it to rotate together. The relative rotation of the two right - angled gears 11 will drive the fixed crushing rollers 20 to rotate together. At this time, the relative rotation of the two crushing rollers 20 can complete the crushing of the waste. After crushing, the particle size of the waste becomes smaller and the shape is more regular. In the subsequent processes such as grinding, screening, and magnetic separation, it can better contact the processing equipment, improving the processing effect and efficiency. During the feeding process by the screw rod 21, by starting the servo - motor two 15, its output shaft will drive the fixed lead screw one 19 to rotate. The lead screw one 19 is rotatably connected between the two fixing blocks 14. As the rotation progresses, the limiting block 18 sleeved on it moves under the action of the thread. The limiting block 18 is movably connected to the crushing box 2 to ensure the stability during the movement. During the movement of the limiting block 18, it will drive the fixed feeding chamber 3 to move together. By the forward and reverse rotation of the servo - motor two 15, the linear reciprocating movement of the feeding chamber 3 is realized. Through the reciprocating movement of the feeding chamber 3, feeding can be carried out at different positions of the crushing box 2.Avoid the concentrated accumulation of waste residue, thereby reducing the blockage phenomenon caused by excessive local accumulation. Moreover, through movement, the waste residue can be evenly distributed in different areas of the two crushing rollers 20, enabling the crushing rollers 20 to fully play their roles and avoiding the situation of local idling or insufficient crushing. This can improve the overall crushing efficiency of the crushing box 2 and process more waste residue within the same time.

[0037] The uppermost synchronous gear 17 in a set of synchronous gears 17 is fixedly connected to the front connecting rod two 16 among the two connecting rods two 16. The annular side surface of the material conveying cavity 3 is fixedly connected with a feed inlet 4. The left surface of the left fixing block 14 among the two fixing blocks 14 is fixedly installed with a servo motor two 15. The output shaft of the servo motor two 15 is fixedly connected with a lead screw one 19. The lower end of the material conveying cavity 3 is fixedly connected with a limiting block 18. The limiting block 18 is movably connected with the crushing box 2. The limiting block 18 is threadedly sleeved on the lead screw one 19. When the connecting rod two 16 rotates, it will drive the fixed synchronous gear 17 to rotate together. When the synchronous gear 17 rotates, it will drive the engaged synchronous belt 12 to rotate together. The synchronous belt 12 will drive the synchronous gears 17 on the other two sides to rotate together. At this time, when the two synchronous gears 17 located below rotate, they will drive the two fixed push rods 13 to rotate together. The two push rods 13 are designed in an elliptical shape and are in contact with the lower surfaces of the two sieve meshes 10. The two sieve meshes 10 are rotatably connected to the two fixing strips 9. As the two push rods 13 rotate, the sieve meshes 10 in contact with them swing up and down under the elliptical driving force. The sieve meshes 10 that swing up and down can make the waste residue produce jumping and tumbling movements on the sieve surface, increasing the contact opportunity between the crushed waste residue particles and the sieve holes, making it easier for the waste residue particles smaller than the sieve holes to pass through the sieve mesh 10, thereby improving the screening efficiency, reducing the residence time of the waste residue on the sieve surface, being able to handle more waste residue, and during the swinging process of the sieve mesh 10, the collision and friction between the waste residue particles and between the particles and the sieve mesh 10 are intensified, which can effectively prevent the waste residue particles from accumulating and blocking at the sieve holes. For viscous materials or waste residue that is prone to agglomeration, this swinging method can break the agglomerates of the waste residue and disperse the waste residue for better screening. The waste residue that does not pass through the sieve holes will be discharged through the discharge port provided on the left side of the sieve mesh 10, while the waste residue that passes through the sieve holes will fall through the fixing strip 9 onto the lower sieve mesh 10 for further screening. The sieve holes of the two sieve meshes 10 are of different sizes to achieve hierarchical screening treatment, gradually screening the waste residue, being able to classify the waste residue more accurately according to different particle size ranges. Compared with single-stage screening, multi-stage screening can control each particle size interval more strictly, reducing the problem of uneven size of the screened particles caused by a single sieve hole size. After multi-stage screening, the particle sizes of the waste residue particles in each particle size grade are more concentrated, facilitating subsequent recycling. The two fixing strips 9 are both inclined to facilitate the movement of the waste residue for discharging. Overall, while crushing the waste residue, screening treatment is realized, and the two are carried out synchronously, which can achieve the continuity of waste residue treatment. The waste residue immediately enters the screening link after being crushed, without intermediate pauses or transfer processes, greatly shortening the entire waste residue treatment time, improving the production efficiency, and the connection between the two processes will be closer, which helps to optimize the production process.

[0038] A connecting plate 5 is fixedly connected to the right surface of the crushing box 2, and a servo motor 6 is fixedly installed on the right surface of the connecting plate 5. The output shaft of the servo motor 6 is fixedly connected to the connecting rod 2 16 located in the front of the two connecting rods 2. The extrusion block 24 is in contact with the surface of the synchronous belt 12. The rear surface of the screw rod 27 is rotatably connected to the rocker 26. The connecting rod 17 is movably connected to the two push rods 13. A slider 25 is fixedly connected to the left surface of the connecting bar 23. The connecting bar 23 is threadedly connected to the screw rod 27. The slider 25 is movably connected to the connecting frame 28. Two baffles 29 are fixedly connected to the upper surfaces of the two screens 10. In order to ensure the stability of screening during long-term use, the fixed screw rod 27 is driven to rotate by rotating the rocker 26. During the rotation of the screw rod 27, the connecting bar 23 sleeved on it is moved accordingly by the action of the thread. The connecting bar 23 is movably connected to the connecting frame 28 through the slider 25 fixed thereon. Dynamic connection, thereby ensuring stability during movement. The connecting strip 23 will drive the fixed extrusion block 24 to move together during the movement. The extrusion block 24 fits the surface of the synchronous belt 12, and will push the synchronous belt 12 to move together as the movement proceeds, generating pressure on the surface of the synchronous belt 12, thereby keeping the synchronous belt 12 in a suitable tensioning state at all times, avoiding slippage caused by relaxation of the synchronous belt 12, thereby ensuring the synchronization and stability of the operation of the crushing and screening mechanisms, and improving the efficiency and quality of waste slag treatment. Appropriate tensioning force can make the synchronous belt 12 evenly stressed, reduce local wear and fatigue. If the synchronous belt 12 is too tight, it will increase its internal stress, accelerate aging and wear. If it is too loose, it will cause uneven friction between the synchronous belt 12 and the synchronous gear 17, and will also affect the life of the synchronous belt 12. By adjusting the tensioning force, the service life of the synchronous belt 12 can be extended and the maintenance cost of the device can be reduced.

[0039] A method for efficiently collecting and treating industrial silicon production waste residue, the method comprising the following steps:

[0040] S1: The collected waste residue is transported according to the production layout through a flexibly adjustable transport mechanism. During the transport process, the spiral rod 21 in the transport cavity 3 is used to transport the material to prevent the waste residue from being blocked and ensure the continuity of the transport;

[0041] S2: Connect the crushing equipment and the screening equipment to the same motor, and realize the coordinated operation of the two by means of the synchronous control of the servo motor 6. Driven by the servo motor 6, the two crushing rollers 20 start to work, crushing the large pieces of waste slag into smaller particles, in preparation for subsequent screening;

[0042] S3: When the crushing equipment starts working, the screening equipment responds immediately and screens the waste residue in time, reducing the intermediate waiting time and greatly improving the processing efficiency;

[0043] S4: The screening device adopts a multi-stage screening design. Screens 10 with different screen hole sizes are arranged in sequence in the screening device. Through step-by-step screening, refined grading of the waste residue is achieved, meeting the strict requirements of different users for the particle size of the waste residue. At the same time, the oscillating screen 10 design is adopted, and the push rod 13 is used to drive the screen 10 to swing up and down, effectively preventing screen hole blockage and improving the screening accuracy.

[0044] Working principle:

[0045] First step, during use, the waste residue is put into the feed inlet 4. The waste residue put into the feed inlet 4 will fall into the material conveying cavity 3. By starting the third servo motor 22, its output shaft will drive the fixed screw rod 21 to rotate. When the screw rod 21 rotates, it can stably convey the waste material. Whether it is block-shaped or granular waste residue, it can be smoothly conveyed to the crushing box 2 through the push of the screw rod 21. At this time, start the first servo motor 6, and its output shaft will drive the fixed connecting rod two 16 to rotate. During the rotation of the connecting rod two 16, it will drive the fixed right-angle gear 11 to rotate. The rotation of the right-angle gear 11 will drive the right-angle gear 11 on the other side meshing with it to rotate together. The relative rotation of the two right-angle gears 11 will drive the fixed crushing roller 20 to rotate together. At this time, the relative rotation of the two crushing rollers 20 can complete the crushing of the waste material. After crushing, the particle size of the waste material becomes smaller and the shape is more regular. In the subsequent processes such as grinding, screening, and magnetic separation, it can better contact the processing equipment, improving the processing effect and efficiency. And during the feeding process by the screw rod 21, by starting the second servo motor 15, its output shaft will drive the fixed screw rod one 19 to rotate. The screw rod one 19 is rotationally connected between the two fixed blocks 14. As the rotation progresses, the limiting block 18 sleeved on it moves under the action of the thread. The limiting block 18 is movably connected to the crushing box 2 to ensure stability during the movement. The limiting block 18 will drive the fixed material conveying cavity 3 to move together during the movement. By the forward and reverse rotation of the second servo motor 15, a linear reciprocating motion of the material conveying cavity 3 is realized. Through the reciprocating movement of the material conveying cavity 3, feeding can be carried out at different positions of the crushing box 2, avoiding the concentrated accumulation of waste residue, thus reducing the blockage phenomenon caused by excessive local accumulation. And through the movement, the waste residue can also be evenly distributed in different areas of the two crushing rollers 20, enabling the crushing rollers 20 to give full play to their roles and avoiding the situation of local idling or insufficient crushing. In this way, the overall crushing efficiency of the crushing box 2 can be improved, and more waste residue can be processed in the same time.

[0046] In the second step, the connecting rod two 16 will drive the fixed synchronous gear 17 to rotate together during the rotation process. When the synchronous gear 17 rotates, it will drive the engaged synchronous belt 12 to rotate together. The synchronous belt 12 will drive the synchronous gears 17 on the other two sides to rotate together. At this time, when the two synchronous gears 17 located below rotate, they will drive the two fixed push rods 13 to rotate together. The two push rods 13 are designed in an elliptical shape and are in contact with the lower surfaces of the two sieve meshes 10. The two sieve meshes 10 are rotatably connected to the two fixed bars 9. As the two push rods 13 rotate, the sieve meshes 10 in contact with them are in an up-and-down swinging state under the elliptical driving force. The up-and-down swinging sieve meshes 10 can make the waste residue generate jumping and tumbling movements on the sieve surface, increasing the contact opportunities between the crushed waste residue particles and the sieve holes, making it easier for the waste residue particles smaller than the sieve holes to pass through the sieve mesh 10, thereby improving the screening efficiency, reducing the residence time of the waste residue on the sieve surface, being able to process more waste residue, and during the swinging process of the sieve mesh 10, the collisions and frictions between the waste residue particles and between the particles and the sieve mesh 10 are intensified, which can effectively prevent the waste residue particles from accumulating and blocking at the sieve holes. For viscous materials or waste residue that is prone to agglomeration, this swinging method can break the agglomerates of the waste residue and disperse the waste residue, making it better for screening. The waste residue that does not pass through the sieve holes will be discharged through the discharge port provided on the left side of the sieve mesh 10, while the waste residue that passes through the sieve holes will fall through the fixed bar 9 into the sieve mesh 10 below for further screening. The sieve holes of the two sieve meshes 10 are of different sizes to achieve hierarchical screening treatment, gradually screening the waste residue, being able to classify the waste residue more precisely according to different particle size ranges. Compared with single-stage screening, multi-stage screening can control each particle size range more strictly, reducing the problem of uneven sizes of the screened particles caused by a single sieve hole size. After multi-stage screening, the particle sizes of the waste residue particles in each size grade are more concentrated, facilitating subsequent recycling. The two fixed bars 9 are both inclined to facilitate the movement of the waste residue for discharging. Overall, while crushing the waste residue, screening treatment is achieved, and the two are carried out synchronously, enabling the continuity of waste residue treatment. The waste residue immediately enters the screening link after being crushed, without an intermediate pause or transfer process, greatly shortening the entire waste residue treatment time, improving production efficiency, and the connection between the two processes will be closer, helping to optimize the production process.

[0047] The third step is that in order to ensure the stability of screening during long-term use, the fixed screw rod 27 is driven to rotate by rotating the rocker 26. During the rotation of the screw rod 27, the connecting strip 23 sleeved thereon is moved accordingly by the action of the thread. The connecting strip 23 is movably connected to the connecting frame 28 through the slider 25 fixed thereon, thereby ensuring stability during the movement. During the movement, the connecting strip 23 will drive the fixed extrusion block 24 to move together. The extrusion block 24 is in contact with the surface of the synchronous belt 12, and as the movement proceeds, it will push the synchronous belt 12 to move together, generating pressure on the surface of the synchronous belt 12, thereby Keep the synchronous belt 12 in a suitable tension state at all times to avoid slipping caused by relaxation of the synchronous belt 12, thereby ensuring the synchronization and stability of the crushing and screening mechanism operations and improving the efficiency and quality of waste slag treatment. Appropriate tension can evenly stress the synchronous belt 12 and reduce local wear and fatigue. If the synchronous belt 12 is too tight, its internal stress will increase, accelerating aging and wear. If it is too loose, it will cause uneven friction between the synchronous belt 12 and the synchronous gear 17, which will also affect the life of the synchronous belt 12. By adjusting the tension, the service life of the synchronous belt 12 can be extended and the maintenance cost of the device can be reduced.
