Description

Technical Field

[0001] The present invention relates to the technical field of mine tailing sludge treatment, and particularly to a device for the resource recycling of mine tailing sludge solid waste. Background Art

[0002] Mining is an important industrial activity. However, a large amount of tailing sludge is generated during this process. The quantity of this tailing sludge is extremely huge. If not properly treated, a series of serious problems will be caused. First of all, they will occupy a large amount of land resources. As mining continues, the tailing sludge piles up like a mountain, continuously encroaching on the originally available land and affecting the normal use of the surrounding land.

[0003] Currently, in the field of mine tailing sludge treatment, there are indeed some corresponding treatment methods. However, these methods have exposed many drawbacks in practical applications. Among them, the two problems of low treatment efficiency and insufficient resource utilization degree are particularly prominent. In terms of treatment efficiency, taking the existing tailing sludge treatment device as an example, there are obvious deficiencies in the key link of breaking and mixing the tailing sludge. During the actual operation process, due to the unreasonable design or operating parameters of the device, the situation of uneven mixing often occurs. This uneven mixing causes some tailing sludge to not fully contact with other substances, resulting in a large amount of sludge accumulating in certain corners or specific areas of the device. This not only affects the normal operation of this link but also forces the entire treatment process to be interrupted or slowed down, greatly reducing the treatment efficiency.

[0004] Looking at the aspect of resource utilization degree again, the different sizes of impurities in the tailing sludge have become a thorny technical problem. Due to the huge difference in the sizes of the impurities, it is very difficult for the existing treatment devices to effectively screen and separate them. During the subsequent treatment process, these impurities of different sizes will interfere with the normal progress of other treatment steps, such as affecting the thoroughness of chemical reactions and reducing the accuracy of physical separation. Eventually, the treatment effect of the tailing sludge is poor, and it is difficult to achieve a high degree of resource utilization.

[0005] Therefore, the present invention proposes a device for the resource recycling of mine tailing sludge solid waste. Summary of the Invention

[0006] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a device for the resource recycling of mine tailing sludge solid waste.

[0007] To achieve the above object, the present invention adopts the following technical solution: A device for the resource recycling of mine tailing sludge solid waste, including the main body of the tailing sludge recovery device, the main body of the tailing sludge recovery device includes a conveying and dispersing component, a screening component, a material processing component, and a lifting component. The screening component is arranged on the top of the material processing component, the conveying and dispersing component is arranged on the top of the screening component, and the lifting component is arranged on one side of the conveying and dispersing component and the material processing component;

[0008] The screening component includes a screening frame, a triangular support mounting frame is arranged on the screening frame, a screening bed is rotatably connected to the triangular support mounting frame, a vibration driving mechanism is arranged below the triangular support mounting frame inside the screening bed, the vibration driving mechanism is connected to the triangular support mounting frame, a first limiting frame is arranged on one side of the triangular support mounting frame on the screening frame, the first limiting frame is connected to the screening bed, and a second limiting frame is arranged on the other side of the triangular support mounting frame on the screening frame, the second limiting frame is connected to the screening bed.

[0009] As a preferred implementation manner, a first support frame and a second support frame are arranged on the top of the screening frame. There are two second support frames in total. The screening frame is provided with a first material dropping port below the screening bed, and a second material dropping port is arranged on one side of the first material dropping port on the screening frame.

[0010] The beneficial effect of adopting the above further scheme is: In the structure of the entire tailing sludge treatment equipment, the first support frame and the second support frame play a crucial role. They provide a stable and reliable installation foundation for the conveying frame. The two cooperate with each other, just like a solid skeleton, accurately carrying the conveying frame. Through this ingenious design, the screening frame and the conveying frame are closely connected, forming an organic whole between them, ensuring the smooth transition of materials between these two parts. Further, in the structure of the screening frame, the first material dropping port arranged at the bottom of the screening bed has a unique function. When the material is placed on the screening bed for screening operation, the material that meets the screening standard will smoothly pass through the first material dropping port under the vibration and screening of the screening bed, and then accurately fall into the screening cavity for subsequent fine screening and processing. At the same time, those materials that fail to pass through the screening of the screening bed will roll towards the side of the second material dropping port under the combined influence of their own gravity and vibration force during the continuous vibration of the screening bed. These substandard materials will finally pass through the second material dropping port and smoothly enter the crushing cavity for subsequent crushing processing, thus providing a strong guarantee for the coherence and efficiency of the entire tailing sludge treatment process.

[0011] As a preferred embodiment, the conveying and dispersing assembly includes a conveying frame, the bottom of the conveying frame is connected to a first support frame and a second support frame, a screw propeller is rotatably connected to the conveying frame, one side of the top of the screw propeller is fixedly communicated with a feed box, a driving mechanism is arranged on one side of the conveying frame away from the feed box, and the output end of the driving mechanism is connected to the screw propeller.

[0012] The beneficial effect of adopting the above further scheme is that in the entire tailings sludge treatment system, the conveying frame plays an indispensable role. It provides a stable rotational connection support structure for the screw propeller. This rotational connection method ensures that the screw propeller can rotate flexibly on the conveying frame, laying a foundation for subsequent material conveying and processing work. It should be noted that the screw propellers are not arranged singly, but two are provided in total. This design of double propellers can greatly improve the efficiency and uniformity of material processing. At this time, the driving mechanism begins to play a key role. Through a specific connection method, the output end of the driving mechanism is closely connected to the screw propeller. When the driving mechanism is started, the power generated by it will be accurately transmitted to the screw propeller, driving the screw propeller to rotate. During the rotation of the screw propeller, the material on one side of the feed box will be pushed by the screw propeller and gradually move towards the other side of the feed box, realizing the stable conveying of the material. Moreover, this conveying is not a simple translation. Under the special thread structure and rotational action of the screw propeller, the material will also be fully stirred. This stirring effect can disperse the material that may have clumped or aggregated together, making the particles of the material more uniform, thus completing the pretreatment work of the material. This series of operation processes is crucial in the entire tailings sludge treatment process, providing a high-quality material basis for subsequent more refined treatment links.

[0013] As a preferred embodiment, a cover plate is rotatably connected to the feed box, an upper protective cover is arranged on the conveying frame above the screw propeller, a protective cover is arranged on the side of the driving mechanism away from the screw propeller, and heat dissipation holes are formed in the protective cover.

[0014] The beneficial effects of adopting the above further solution are as follows: In the entire tailings sludge treatment device, the top of the feed box achieves an effective protection function through ingenious design. A cover plate is rotatably connected to the feed box, and the role of this cover plate cannot be underestimated. When the equipment is operating normally, the cover plate is in a closed state, closely fitting the top opening of the feed box, forming a reliable sealing line of defense. During the tailings sludge treatment process, materials are continuously fed into the feed box. When the materials accumulate to a certain extent and the screw propeller is continuously rotating, an upward acting force will be generated. Without the protection of the cover plate, the materials are very likely to be lifted upward under this acting force and then overflow through the opening of the feed box, resulting in pollution of the working area and waste of materials. The presence of the cover plate effectively avoids the occurrence of this problem. At the same time, there are also comprehensive protection measures for the drive mechanism. The protective cover plays an important role. It is like a loyal guard, protecting the drive mechanism. During the long-term use of the equipment, the drive mechanism may be damaged from various aspects, such as the intrusion of dust and debris, or accidental collisions, etc. The protective cover can effectively block these potential risk factors, ensuring that the drive mechanism operates in a relatively stable and safe environment. Moreover, the design of the protective cover is very delicate, with heat dissipation holes opened on it. When the drive mechanism generates heat during operation, these heat dissipation holes are like tiny heat dissipation channels, and the hot air can be dissipated in time through the heat dissipation holes, thus ensuring that the drive mechanism will not malfunction due to overheating, extending the service life of the drive mechanism, and ensuring the stable operation of the entire equipment.

[0015] As a preferred implementation manner, the material processing component includes a processing box. A screening chamber and a crushing chamber are provided in the processing box. A screening plate is provided in the screening chamber. Damping members are provided at the four corners of the screening plate in the screening chamber. A connecting member is provided on the other side of the damping member, and the connecting member is connected to the inner wall of the screening chamber. A total of eight damping members are provided, and four of the eight damping members are in a group. The two groups of damping members are symmetric with each other with the screening plate as the axis.

[0016] The beneficial effects of adopting the above further solution are as follows: Through the careful setting of the material handling component, which undertakes the important mission of storing materials and further processing them, when the materials fall into the screening chamber after the previous process, they will first fall on the screening plate. This screening plate is not an ordinary static structure but has a unique dynamic design. When the materials generate a downward pressure on the upper screening plate, the damping components at the bottom will deform accordingly. This deformation is a clever mechanical reaction that enables the screening plate to displace downward. During this process, the damping components at the top also play a role. When the damping components at the bottom deform due to pressure to a certain extent, the damping components at the top will drive the screening plate to reset again by virtue of their elasticity and mechanical properties. Just like this, under the coordinated action of the damping components at the bottom and the top, the screening plate starts to vibrate reciprocally. This reciprocal vibration is of great significance for material handling. During the vibration of the screening plate, the materials on its surface will be further subdivided under this regular movement. The materials that may originally be agglomerated or of uneven size will gradually separate according to their particle sizes under the acting force generated by the vibration. The fine particle materials that meet the requirements will pass through the strip-shaped grooves on the screening plate and finally fall into the collection box for storage. Moreover, this reciprocal movement has an additional advantage, that is, it can effectively avoid a common problem. When the screening plate is in a static state for a long time, some viscous components or small particle impurities in the materials may block the strip-shaped grooves on the screening plate, which will seriously affect the screening efficiency and effect. However, through this reciprocal vibration, the materials in the strip-shaped grooves are always in a dynamic change, greatly reducing the possibility of blockage and ensuring the smooth progress of the screening process.

[0017] As a preferred implementation manner, a collection box is slidably connected below the screening plate in the screening chamber. A base is provided at the bottom of the processing box, and an installation groove is formed on the base. A diversion seat is provided at the bottom of the crushing chamber.

[0018] The beneficial effects of adopting the above further solution are as follows: Through the ingenious setting of the collection box, it undertakes the important responsibility of collecting the materials screened by the screening plate. The design of the collection box is unique. It is arranged inside the screening cavity in a pull-out manner. This pull-out design greatly facilitates the operation process. When the materials in the collection box gradually accumulate until it is full, the staff can simply pull out the collection box from the screening cavity and conveniently transfer the collected materials. This process is simple and efficient, without complex unloading operations, effectively improving the continuity and efficiency of material processing. Further, at the bottom of the entire device, the base plays a key stabilizing role. There is an installation groove on the base, and this installation groove has a clear function. During the installation of the device, by firmly installing the installation groove and the corresponding installation points with bolts, it can effectively prevent the overall device from shifting during use. When the equipment is running, due to the operation of various internal components and the flow of materials, various forces may act. Without stable installation, these forces may cause the center of gravity of the device to shift, thereby causing the equipment to tilt. However, this installation method through the installation groove and bolts provides reliable fixation for the device, greatly improving the stability of the device during operation, ensuring the normal operation of the equipment and the accuracy of material processing. At the same time, the setting of the diversion seat is also an important part of the design of the entire device. The main function of the diversion seat is to smoothly guide the crushed materials into the feeding sleeve. During the material crushing process, without effective diversion measures, the crushed materials are easily piled up in the crushing cavity. This piling up not only affects the normal operation of the crushing cavity, may cause damage to the crushing equipment, but also hinders the material processing process. The existence of the diversion seat is like an accurate guiding channel, ensuring that the crushed materials can enter the feeding sleeve along the predetermined path, maintaining the smooth progress of the material processing process.

[0019] As a preferred implementation manner, a crushing roller is rotatably connected inside the crushing cavity. There are two groups of the crushing rollers in total, and driving gears are rotatably connected to the outside of the processing box for both groups of the crushing rollers. The driving gears penetrate through the processing box and are connected to the crushing rollers. A linkage belt is wound around each driving gear, and a first driving motor is arranged on each driving gear. The output ends of the two first driving motors are respectively connected to the two driving gears.

[0020] The beneficial effects of adopting the above further solution are as follows: In the entire tailings sludge treatment system, the crushing rollers play a crucial role. When the materials pass through the preliminary screening process, the unqualified materials will fall into the crushing chamber. At this time, the crushing rollers will start to exert their powerful secondary processing function. It is like an accurate and powerful "giant jaw", which re-crushes these materials that are too large and do not meet the requirements. Two groups of crushing rollers, one above the other, are specially designed here. This unique layout is to process larger materials more efficiently. When these large pieces of materials enter the crushing chamber, the two groups of crushing rollers work together and re-crush the materials through mutual cooperation. This design fully considers the size of the materials and the difficulty of crushing, and can ensure that large pieces of materials of different sizes can be effectively processed. Further, the entire crushing process requires a stable and reliable power source and transmission mechanism to drive the rotation of the crushing rollers. The first drive motor is the core of this power. After it starts, it will drive one of the drive gears in the same group to start rotating. The rotation of this drive gear is cleverly transmitted through a linkage belt. The linkage belt is like an invisible bond, evenly transmitting the power to the remaining drive gears in the same group, thus realizing the rotation function of the entire crushing roller. It is worth noting that the rotation directions of the two groups of crushing rollers are carefully designed, and they rotate inwards in opposite directions. This rotation method enables the two groups of crushing rollers to exert a mutual extrusion effect when working. When the materials are between the two groups of crushing rollers, this mutual extrusion force will crush the materials, achieving efficient crushing and processing. This design can not only effectively crush the materials, but also ensure the stability and continuity of the crushing process, providing materials with appropriate particle sizes for the subsequent material processing process, and ensuring the efficient operation of the entire tailings sludge treatment system.

[0021] As a preferred implementation manner, the lifting assembly includes a lifting cylinder, a lifting screw blade is rotatably connected inside the lifting cylinder, a feeding sleeve is fixedly communicated with the upper part of the lifting cylinder, the other end of the feeding sleeve is fixedly communicated with the crushing chamber, a discharging sleeve is fixedly communicated with the lifting cylinder, the other end of the discharging sleeve is fixedly communicated with the feeding box, a second drive motor is arranged at the top of the lifting cylinder, and the output end of the second drive motor is connected with the lifting screw blade.

[0022] The beneficial effects of adopting the above further solution are as follows: By enhancing the scientific setting of the components, it brings the possibility of further optimizing the entire tailings sludge treatment process. Its core function is to be able to reintroduce the crushed material into the feed box, thereby initiating the key link of secondary screening. During this process, the diversion seat plays an indispensable guiding role. When the material is crushed in the crushing chamber, the diversion seat is like an accurate guide, guiding the crushed material into the feed sleeve in an orderly manner. This feed sleeve is an important entrance for the material to enter the lifting component, and its special design ensures that the material can smoothly enter the subsequent lifting process. At this time, the second drive motor starts. It is the power source for the rotation of the lifting screw blade. When the second drive motor is turned on, it generates stable and strong power, driving the lifting screw blade to rotate. The lifting screw blade has a unique spiral structure. This structural design enables it to fully contact the material during rotation and generate an upward acting force. Under the action of the lifting screw blade, the material in the lifting cylinder begins to be slowly lifted upward. This process is continuous and stable. The material is pushed by the lifting screw blade and gradually moves upward along the inner wall of the lifting cylinder until the material is lifted to the discharge sleeve. The discharge sleeve is like a bridge, redirecting the lifted material back into the feed box. In this way, the material can be screened again in the feed box. Through secondary screening, the precision and quality of material treatment can be further improved, ensuring that the treatment effect of the entire tailings sludge treatment system is more in line with expectations, reducing the generation of unqualified materials, and improving the efficiency of resource recycling and utilization.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0024] 1. In the present invention, in the entire tailings sludge treatment system, the screening component plays a crucial role. It is mainly responsible for the fine screening of the materials input into the screening bed. During this process, the vibration drive mechanism plays a key role. After the vibration drive mechanism is started, it generates regular vibrations and uses the triangular support mounting frame as a stable support point to transmit this vibration to the screening bed, causing the screening bed to swing left and right. This swinging method is not random but an efficient movement achieved under a carefully designed mechanical structure. When the screening bed swings left and right, the materials on its surface will undergo corresponding displacement and separation. Among them, the materials with particle sizes smaller than the gaps on the screening bed will, under the action of inertia and gravity generated by the swinging of the screening bed, smoothly pass through the first discharge port and then accurately fall into the screening cavity to prepare for the subsequent treatment process. For the materials with larger particle sizes that cannot pass through the gaps of the screening bed, they will gradually roll towards the side of the second limiting frame during the swinging process of the screening bed, which is determined by the special design and swinging direction of the screening bed. These rolling materials will ultimately pass through the second discharge port and then enter the crushing cavity for crushing processing, thereby realizing the classification treatment of materials with different particle sizes. Further, the first limiting frame and the second limiting frame have unique functions in the entire screening process. They mainly limit the swinging amplitude of the screening bed. This limiting effect is very crucial as it can ensure that the swinging of the screening bed is within a reasonable range, avoiding the influence on the screening effect due to too large or too small swinging amplitude. It is worth noting that the height of the first limiting frame is greater than that of the second limiting frame. This design of the height difference is well-considered. It is precisely because of this design that the materials that cannot pass through the gaps of the screening bed can, under the guidance of gravity and the limiting frame, smoothly enter the second discharge port during the swinging of the screening bed, ensuring the smoothness and accuracy of the entire screening and material flow process.

[0025] 2. In the present invention, in the entire tailings sludge treatment system, the conveying rack plays an indispensable role. It provides a stable rotational connection support structure for the screw propulsion blade. This rotational connection method ensures that the screw propulsion blade can rotate flexibly on the conveying rack, laying a foundation for subsequent material conveying and treatment work. It should be noted that the screw propulsion blades are not set singly, but two are provided in total. This design of double propulsion blades can greatly improve the efficiency and uniformity of material treatment. At this time, the driving mechanism begins to play a key role. Through a specific connection method, the output end of the driving mechanism is closely connected to the screw propulsion blade. When the driving mechanism is started, the power generated by it will be accurately transmitted to the screw propulsion blade, driving the screw propulsion blade to rotate. During the rotation of the screw propulsion blade, the material on one side of the feed box will be gradually pushed towards the other side of the feed box under the push of the screw propulsion blade, realizing the stable conveying of the material. Moreover, this conveying is not a simple translation. Under the special screw structure and rotational action of the screw propulsion blade, the material will also be fully stirred. This stirring effect can disperse the material that may have caked or aggregated together, making the particles of the material more uniform, thus completing the pretreatment work of the material. This series of operation processes is crucial in the entire tailings sludge treatment process, providing a high-quality material basis for subsequent more refined treatment links.

[0026] 3. In the present invention, through the elaborate setting of the material handling component, which undertakes the important mission of storing materials and further processing them, when the materials fall into the screening chamber after the previous process, they will first drop onto the screening plate. This screening plate is not an ordinary static structure but has a unique dynamic design. When the materials generate a downward pressure on the upper screening plate, the damping member at the bottom will deform accordingly. This deformation is a clever mechanical reaction that enables the screening plate to displace downward. During this process, the top damping member also plays a role. When the bottom damping member deforms due to pressure to a certain extent, the top damping member will drive the screening plate to reset again by virtue of its own elasticity and mechanical properties. Just like this, under the coordinated action of the bottom and top damping members, the screening plate starts to vibrate reciprocally. This reciprocal vibration is of great significance for material handling. During the vibration of the screening plate, the materials on its surface will be further subdivided under this regular movement. The materials that may originally be agglomerated or have uneven sizes will gradually separate according to their particle sizes under the acting force generated by the vibration. The fine particle materials that meet the requirements will pass through the strip-shaped grooves on the screening plate and finally fall into the collection box for storage. Moreover, this reciprocating movement has an additional advantage, that is, it can effectively avoid a common problem. When the screening plate is in a static state for a long time, some viscous components or small particle impurities in the materials may block the strip-shaped grooves on the screening plate, which will seriously affect the screening efficiency and effect. However, through this reciprocal vibration, the materials in the strip-shaped grooves are always in a dynamic change, greatly reducing the possibility of blockage and ensuring the smooth progress of the screening process.

[0027] 4. In the present invention, in the entire tailings sludge treatment system, the crushing rollers play a crucial role. After the materials pass through the preliminary screening process, those unqualified materials will fall into the crushing chamber. At this time, the crushing rollers start to exert their powerful secondary processing function. It is like an accurate and powerful "giant jaw", re-crushing these materials with larger volumes and not meeting the requirements. Here, two sets of crushing rollers, one on top and one below, are specially designed. This unique layout is for more efficient processing of materials with larger volumes. When these large pieces of materials enter the crushing chamber, the two sets of crushing rollers work together and re-crush the materials through mutual cooperation. This design fully considers the size of the materials and the difficulty of crushing, and can ensure that large pieces of materials of different sizes can be effectively processed. Further, the entire crushing process requires a stable and reliable power source and transmission mechanism to drive the rotation of the crushing rollers. The first driving motor is the core of this power. After it starts, it drives one of the driving gears in the same group to start rotating. The rotation of this driving gear is cleverly transmitted through the linkage belt. The linkage belt is like an invisible bond, evenly transmitting the power to the remaining driving gears in the same group, thus realizing the rotation function of the entire crushing roller. It is worth noting that the rotation directions of the two sets of crushing rollers are carefully designed, and they rotate inwards in opposite directions. This rotation method enables the two sets of crushing rollers to have a mutual extrusion effect when working. When the materials are between the two sets of crushing rollers, this mutual extrusion force will crush the materials, achieving efficient crushing and processing. This design can not only effectively crush the materials, but also ensure the stability and continuity of the crushing process, providing materials with appropriate particle sizes for the subsequent material processing process and guaranteeing the efficient operation of the entire tailings sludge treatment system.

[0028] 5. In the present invention, through the scientific setting of the lifting component, it brings the possibility of further optimizing the entire tailings sludge treatment process. Its core function is to be able to reintroduce the crushed material into the feed box, thus initiating the key link of secondary screening. In this process, the diversion seat plays an indispensable guiding role.

Through secondary screening, the precision and quality of material treatment can be further improved, ensuring that the treatment effect of the entire tailings sludge treatment system is more in line with expectations, reducing the generation of unqualified materials, and improving the efficiency of resource recovery and utilization.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Such as Figures 1-7As shown in the figure, the present invention provides a technical solution: a device for the resource recycling of mine tailing sludge solid waste, including the main body 1 of the tailing sludge recycling device. The main body 1 of the tailing sludge recycling device includes a conveying and dispersing component 2, a screening component 3, a material processing component 4, and a lifting component 5. A screening component 3 is arranged at the top of the material processing component 4, a conveying and dispersing component 2 is arranged at the top of the screening component 3, and the lifting component 5 is arranged on one side of the conveying and dispersing component 2 and the material processing component 4;The screening component 3 includes a screening frame 31. A triangular support mounting frame 33 is arranged on the screening frame 31. A screening bed 36 is rotatably connected to the triangular support mounting frame 33. A vibration driving mechanism 35 is arranged below the triangular support mounting frame 33 inside the screening bed 36. The vibration driving mechanism 35 is connected to the triangular support mounting frame 33. A first limiting frame 32 is arranged on one side of the triangular support mounting frame 33 on the screening frame 31. The first limiting frame 32 is connected to the screening bed 36. A second limiting frame 34 is arranged on the other side of the triangular support mounting frame 33 on the screening frame 31. The second limiting frame 34 is connected to the screening bed 36. A first support frame 311 and a second support frame 312 are arranged at the top of the screening frame 31. There are two second support frames 312 in total. A first material discharge port 313 is formed below the screening bed 36 on the screening frame 31. A second material discharge port 314 is formed on one side of the first material discharge port 313 on the screening frame 31. In the entire tailings sludge treatment system, the screening component 3 plays a crucial role. It is mainly responsible for the fine screening of the materials input into the screening bed 36. In this process, the vibration driving mechanism 35 plays a key role. When the vibration driving mechanism 35 is started, it will generate regular vibrations and use the triangular support mounting frame 33 as a stable support point to transmit this vibration to the screening bed 36, enabling the screening bed 36 to swing left and right. This swinging method is not random but an efficient movement achieved under a carefully designed mechanical structure. When the screening bed 36 swings left and right, the materials on its surface will undergo corresponding displacement and separation. Among them, the materials with particle sizes smaller than the gaps on the screening bed 36 will, under the action of inertia and gravity generated by the swinging of the screening bed 36, smoothly pass through the first material discharge port 313 and then accurately fall into the screening chamber 42 to prepare for the subsequent treatment process. For the materials with larger particle sizes that cannot pass through the gaps of the screening bed 36, they will gradually roll towards the side of the second limiting frame 34 during the swinging process of the screening bed 36. This is determined by the special design and swinging direction of the screening bed 36. These rolling materials will ultimately pass through the second material discharge port 314 and then enter the crushing chamber 43 for crushing and processing, thus realizing the classification treatment of materials with different particle sizes. Further, the first limiting frame 32 and the second limiting frame 34 have unique functions in the entire screening process. They mainly limit the swinging amplitude of the screening bed 36. This limiting effect is very crucial. It can ensure that the swinging of the screening bed 36 is within a reasonable range and avoid affecting the screening effect due to too large or too small swinging amplitude. It should be noted that the height of the first limiting frame 32 is greater than the height of the second limiting frame 34. This design of the height difference is well-considered. It is precisely because of this design that the materials that cannot pass through the gaps of the screening bed 36 can, under the guidance of gravity and the limiting frame during the swinging of the screening bed 36, smoothly enter the second material discharge port 314 according to the established process, ensuring the smoothness and accuracy of the entire screening and material flow process and solving the technical problem of the separation of tailings sludge materials.

[0044] Furthermore, such as Figure 2 - Figure 5As shown: The material handling component 4 includes a processing box 41. A screening chamber 42 and a crushing chamber 43 are provided inside the processing box 41. A screening plate 44 is arranged in the screening chamber 42. Damping members 45 are arranged at the four corners of the screening plate 44 in the screening chamber 42. On the other side of the damping member 45, there is a connecting member 451, and the connecting member 451 is connected to the inner wall of the screening chamber 42. A total of eight damping members 45 are provided, and four of the eight damping members 45 are in a group. The two groups of damping members 45 are symmetric with each other with the screening plate 44 as the axis. A crushing roller 431 is rotatably connected in the crushing chamber 43. A total of two groups of crushing rollers 431 are provided. And on the outside of the processing box 41, a driving gear 432 is rotatably connected to each group of crushing rollers 431. The driving gear 432 penetrates through the processing box 41 and is connected to the crushing roller 431. A linkage belt 433 is wound around each group of driving gears 432. A first driving motor 434 is arranged on each group of driving gears 432. The output ends of the two first driving motors 434 are respectively connected to the two driving gears 432. Through the elaborate setting of the material handling component 4, it undertakes the important mission of storing materials and further processing the materials. When the materials fall into the screening chamber 42 after the previous process, they will first fall on the screening plate 44. This screening plate 44 is not an ordinary static structure, but has a unique dynamic design. When the materials generate a downward pressure when falling on the screening plate 44, the damping members 45 at the bottom will deform accordingly. This deformation is a clever mechanical reaction, which enables the screening plate 44 to displace downward. During this process, the damping members 45 at the top also play a role. When the damping members 45 at the bottom deform due to pressure to a certain extent, the damping members 45 at the top will drive the screening plate 44 to reset by virtue of their own elasticity and mechanical properties. Just like this, under the coordinated action of the damping members 45 at the bottom and the top, the screening plate 44 starts to vibrate reciprocally. This reciprocal vibration is of great significance for material handling. During the vibration of the screening plate 44, the materials on its surface will be further subdivided under this regular movement. The materials that may originally be agglomerated or of uneven size will gradually separate according to their particle sizes under the acting force generated by the vibration. The fine particle materials that meet the requirements will pass through the strip-shaped grooves on the screening plate 44 and finally fall into the collection box 46 for storage. Moreover, this reciprocating movement has an additional advantage, that is, it can effectively avoid a common problem. When the screening plate 44 is in a static state for a long time, some viscous components or small particle impurities in the materials may block the strip-shaped grooves on the screening plate 44, which will seriously affect the screening efficiency and effect. However, through this reciprocal vibration, the materials in the strip-shaped grooves are always in a dynamic change, greatly reducing the possibility of blockage and ensuring the smooth progress of the screening process. In the entire tailings sludge treatment system, the crushing roller 431 plays a crucial role. When the materials pass through the previous screening process, the materials that do not meet the standards will fall into the crushing chamber 43. At this time, the crushing roller 431 begins to exert its powerful secondary processing function. It is like an accurate and powerful "giant jaw",These larger-sized and non-compliant materials are re-crushed. Here, two sets of crushing rollers 431, one on top and the other at the bottom, are specially designed. This unique layout is for more efficient processing of larger-sized materials. When these large pieces of materials enter the crushing chamber 43, the two sets of crushing rollers 431 work together and re-crush the materials through mutual cooperation. This design fully considers the size of the materials and the difficulty of crushing, and can ensure that large pieces of materials of different sizes can be effectively processed. Further, the entire crushing process requires a stable and reliable power source and transmission mechanism to drive the rotation of the crushing rollers 431. The first drive motor 434 is the core of this power. After it starts, it drives one of the drive gears 432 in the same group to start rotating. The rotation of this drive gear 432 is cleverly transmitted through the linkage belt 433. The linkage belt 433 is like an invisible bond that evenly transmits the power to the remaining drive gears 432 in the same group, thus realizing the rotation function of the entire crushing roller 431. It is worth noting that the rotation directions of the two sets of crushing rollers 431 are carefully designed. They rotate inwards in opposite directions. This rotation method enables the two sets of crushing rollers 431 to have a mutual extrusion effect when working. When the material is between the two sets of crushing rollers 431, this mutual extrusion force will crush the material, achieving efficient crushing and processing. This design can not only effectively crush the material, but also ensure the stability and continuity of the crushing process, providing materials with appropriate particle sizes for subsequent material processing processes, ensuring the efficient operation of the entire tailings sludge treatment system, and solving the technical problem of secondary processing after the sorting of tailings sludge materials.,

[0045] In the above solution, there is also a problem of easy blockage when transporting tailings materials, such as Figure 3As shown: In this solution, the conveying and dispersing component 2 includes a conveying frame 23. The bottom of the conveying frame 23 is connected to the first support frame 311 and the second support frame 312. A screw propeller 24 is rotatably connected to the conveying frame 23. One side of the top of the screw propeller 24 is fixedly communicated with a feed box 21. A driving mechanism 26 is arranged on the side of the conveying frame 23 away from the feed box 21. The output end of the driving mechanism 26 is connected to the screw propeller 24. In the entire tailings sludge treatment system, the conveying frame 23 plays an indispensable role. It provides a stable rotational connection support structure for the screw propeller 24. This rotational connection method ensures that the screw propeller 24 can rotate flexibly on the conveying frame 23, laying a foundation for subsequent material conveying and processing work. It should be noted that the screw propeller 24 is not arranged singly, but two are provided in total. This design of double propellers can greatly improve the efficiency and uniformity of material processing. At this time, the driving mechanism 26 begins to play a key role. Through a specific connection method, the output end of the driving mechanism 26 is closely connected to the screw propeller 24. When the driving mechanism 26 is started, the power generated by it will be accurately transmitted to the screw propeller 24, driving the screw propeller 24 to rotate. During the rotation of the screw propeller 24, the material on one side of the feed box 21 will be gradually pushed by the screw propeller 24 towards the other side of the feed box 21, realizing the stable conveying of the material. Moreover, this conveying is not a simple translation. Under the special screw structure and rotational action of the screw propeller 24, the material will also be fully stirred. This stirring effect can disperse the material that may have caked or aggregated together, making the particles of the material more uniform, thus completing the pretreatment work of the material. This series of operation processes is crucial in the entire tailings sludge treatment process, providing a high-quality material basis for subsequent more refined treatment links.

[0046] In the above solution, there is also a problem that the material in the feed box 21 will overflow, such as Figure 3As shown: In this solution, a cover plate 22 is rotatably connected to the feed box 21. An upper protective cover 25 is provided above the screw propeller 24 on the conveying frame 23. A protective cover 27 is provided on the side of the driving mechanism 26 away from the screw propeller 24. Heat dissipation holes 271 are provided on the protective cover 27. In the entire tailings sludge treatment device, the top of the feed box 21 realizes an effective protection function through a clever design. The cover plate 22 is rotatably connected to the feed box 21. The role of this cover plate 22 cannot be underestimated. When the equipment is operating normally, the cover plate 22 is in a closed state. It closely fits the top opening of the feed box 21, forming a reliable sealing line of defense. During the tailings sludge treatment process, materials are continuously fed into the feed box 21. When the materials accumulate to a certain extent and the screw propeller 24 is continuously rotating, an upward acting force will be generated. Without the protection of the cover plate 22, the materials are very likely to be lifted upward under this acting force and then overflow through the opening of the feed box 21, resulting in pollution of the working area and waste of materials. The existence of the cover plate 22 effectively avoids the occurrence of this problem. At the same time, there are also comprehensive protection measures for the driving mechanism 26. The protective cover 27 plays an important role. It is like a loyal guard, protecting the driving mechanism 26. During the long-term use of the equipment, the driving mechanism 26 may be damaged from all aspects, such as the intrusion of dust and debris, or accidental collisions, etc. The protective cover 27 can effectively block these potential risk factors, ensuring that the driving mechanism 26 operates in a relatively stable and safe environment. Moreover, the design of the protective cover 27 is very delicate. Heat dissipation holes 271 are provided on it. When the driving mechanism 26 generates heat during operation, these heat dissipation holes 271 are like tiny heat dissipation channels, and the hot air can be dissipated in time through the heat dissipation holes 271, so as to ensure that the driving mechanism 26 will not malfunction due to overheating, extend the service life of the driving mechanism 26, and ensure the stable operation of the entire equipment.

[0047] In the above solution, there are still problems with the collection of the screened tailings sludge materials, such as Figure 5As shown: in the present scheme, a collecting box 46 is slidably connected to the bottom of the screening plate 44 in the screening chamber 42, a base 48 is arranged at the bottom of the processing box 41, a mounting groove 481 is provided on the base 48, and a guide seat 47 is provided at the bottom of the crushing chamber 43. Through the ingenious arrangement of the collecting box 46, it assumes the important responsibility of collecting the materials screened by the screening plate 44. The design of the collecting box 46 is ingenious. It is arranged inside the screening chamber 42 in a pull-out manner. This pull-out design greatly facilitates the operation process. When the materials in the collecting box 46 gradually accumulate until they are full, the staff only needs to easily pull the collecting box 46 out of the screening chamber 42 to conveniently transfer and process the collected materials. This process is simple and efficient, and does not require complicated unloading operations, which effectively improves the continuity and efficiency of material processing. Further, at the bottom of the entire device, the base 48 plays a key stabilizing role, and a mounting groove 481 is provided on the base 48. This mounting groove 481 has a clear function. During the installation of the device, the mounting groove 481 is firmly installed with bolts to the corresponding mounting points. In order to effectively avoid displacement of the entire device during use, when the equipment is running, various forces may be generated due to the operation of various internal components and the flow of materials. If there is no stable installation, these forces may cause the center of gravity of the device to shift, thereby causing the equipment to tilt. This installation method through the installation groove 481 and bolts provides a reliable fixation for the device, greatly improves the stability of the device during operation, and ensures the normal operation of the equipment and the accuracy of material processing. At the same time, the setting of the guide seat 47 is also an important link in the design of the entire device. The main function of the guide seat 47 is to smoothly guide the crushed material into the feed sleeve 55. During the material crushing process, if there is no effective diversion measure, the crushed material is easy to accumulate in the crushing chamber 43. This accumulation will not only affect the normal operation of the crushing chamber 43, but may also cause damage to the crushing equipment, and will also hinder the material processing process. The existence of the guide seat 47 is like a precise guiding channel, ensuring that the crushed material can enter the feed sleeve 55 according to the predetermined path, maintaining the smooth progress of the material processing process.

[0048] The above schemes still have the problem of secondary feeding of crushed tailings sludge materials, such as Figure 5 - Figure 6As shown: In this solution, the lifting component 5 includes a lifting cylinder 51. A lifting screw blade 54 is rotatably connected inside the lifting cylinder 51. The upper part of the lifting cylinder 51 is fixedly communicated with a feeding sleeve 55. The other end of the feeding sleeve 55 is fixedly communicated with the crushing chamber 43. The lifting cylinder 51 is fixedly communicated with a discharging sleeve 53. The other end of the discharging sleeve 53 is fixedly communicated with the feeding box 21. A second driving motor 52 is arranged at the top of the lifting cylinder 51. The output end of the second driving motor 52 is connected to the lifting screw blade 54. Through the scientific setting of the lifting component 5, it brings the possibility of further optimizing the entire tailings sludge treatment process. Its core function is to re-inject the crushed material into the feeding box 21, thus starting the key link of secondary screening. In this process, the diversion seat 47 plays an indispensable guiding role. When the material is crushed in the crushing chamber 43, the diversion seat 47 is like an accurate guide, guiding the crushed material into the feeding sleeve 55 in an orderly manner. This feeding sleeve 55 is an important entrance for the material to enter the lifting component 5. Its special design ensures that the material can smoothly enter the subsequent lifting process. At this time, the second driving motor 52 starts. It is the power source for the rotation of the lifting screw blade 54. When the second driving motor 52 is started, it will generate stable and strong power to drive the lifting screw blade 54 to rotate. The lifting screw blade 54 has a unique spiral structure. This structural design enables it to fully contact the material during rotation and generate an upward acting force. Under the action of the lifting screw blade 54, the material in the lifting cylinder 51 starts to be slowly lifted upward. This process is continuous and stable. The material is pushed by the lifting screw blade 54 and gradually moves upward along the inner wall of the lifting cylinder 51 until the material is lifted to the discharging sleeve 53. The discharging sleeve 53 is like a bridge, redirecting the lifted material back into the feeding box 21. In this way, the material can be screened again in the feeding box 21. Through secondary screening, the precision and quality of material treatment can be further improved, ensuring that the treatment effect of the entire tailings sludge treatment system is more in line with expectations, reducing the generation of unqualified materials, and improving the efficiency of resource recovery and utilization.

[0049] Working principle:

[0050] As Figures 1-7As shown in the figure, first, the device needs to be carefully moved to the designated working position using a suitable transportation tool. During the movement, it is necessary to ensure that all components of the device are not collided or damaged, and its integrity is maintained. After reaching the designated position, then utilize the mounting groove 481 on the device base 48 to firmly install and fix the device to the ground through bolts. When installing the bolts, pay attention to the tightening degree of the bolts to ensure that each bolt can play a stable fixing role, thereby ensuring that the device will not shake or displace during subsequent operation, and thus guaranteeing its stability during operation. When the installation work is successfully completed, flip open the cover plate 22 rotatably connected to the feed box 21, and then slowly and orderly put the tailings sludge material into the feed box 21. During the feeding process, pay attention to controlling the feeding speed and quantity to avoid the feed box 21 being blocked or other problems caused by excessive and too-fast feeding of the material. After the feeding is completed, close the cover plate 22 to form a relatively closed feeding environment. At this time, start the driving mechanism 26. The driving mechanism 26 starts to operate stably and generates power, driving the threaded propeller 24 to rotate. During the rotation of the threaded propeller 24, it comes into full contact with the material, and through its special threaded structure and the thrust generated by rotation, gradually transports the material on one side of the conveying frame 23 to the other side. When the material is successfully displaced to the other side, it will accurately fall above the screening bed 36 through the opening at the bottom of the conveying frame 23. Then, the vibration driving mechanism 35 starts to function. It generates regular vibrations and transmits them to the screening bed 36, driving the screening bed 36 to swing left and right. During the swinging of the screening bed 36, the material smaller than the gap of the screening bed 36, under the action of gravity and the inertia generated by the swinging, falls into the screening chamber 42 through the first discharge port 313, while those materials with larger particle sizes that cannot pass through the gap of the screening bed 36 will roll towards the second discharge port 314 and finally roll into the crushing chamber 43. When the material in the screening chamber 42 comes into contact with the screening plate 44, due to the special vibration design of the screening plate 44, the material will pass through the strip-shaped grooves on the screening plate 44 in this vibrating environment and then fall into the collection box 46 for storage. The material that falls into the crushing chamber 43 is crushed under the powerful crushing action of the crushing roller 431. After the crushing is completed, the crushed material is guided to the screening plate 44 under the ingenious guiding action of the guiding seat 47. At the same time, driven by the second driving motor 52, the lifting threaded blade 54 is driven to rotate. When the lifting threaded blade 54 rotates, it generates an upward lifting force on the material, causing the material in the lifting cylinder 51 to be continuously lifted upward until the material is lifted to the discharge sleeve 53, and the material is re-fed into the feed box 21 for secondary sorting. When all the sorting work is completed, carefully remove the screening bed 36 from the device to facilitate subsequent cleaning and maintenance of the device.
