Description

Technical Field

[0001] This invention relates to the field of slag treatment technology, specifically to a slag recycling and treatment structure for waste incineration power generation. Background Technology

[0002] As is well known, after the waste-to-energy slag is cooled, surface dust and adhering organic matter are removed by water washing. In the subsequent deep processing stage, the aggregate is rendered harmless through high-temperature roasting or chemical stabilization technology. After meeting the standards, it is used to produce permeable bricks, road base fillers, etc. The recovered metals are processed into recycled raw materials after impurity removal and smelting.

[0003] In the existing technology, in order to ensure that the particles are relatively uniform during subsequent aggregate processing, crushing is usually carried out before the water system. However, dust may be emitted during the multiple processes after the slag is discharged from the slag removal device. At the same time, the equipment has relatively simple functions and cannot effectively process the slag in a single operation, making it inconvenient to use. Moreover, the slag processing usually requires adding materials multiple times to avoid blockage or affecting the efficiency of operation, making it inconvenient to use. Based on the above-mentioned situation, we found that it is difficult to avoid the above problems in the slag treatment of existing technologies. Therefore, we propose a slag recycling and treatment structure for waste incineration power generation that can directly process the slag and keep it in a relatively sealed state during the multi-stage treatment process, while improving the uniformity of aggregates, reducing the occurrence of agglomeration, and can process a large amount of slag at a uniform rate. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a slag recycling and processing structure for waste incineration power generation. It has the advantages of being able to directly process the slag and keep it in a relatively sealed state during the multi-stage processing, while improving the uniformity of aggregates, reducing the occurrence of agglomeration, and processing large quantities of slag at a uniform rate.

[0006] (II) Technical Solution

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a slag recycling and processing structure for waste incineration power generation, comprising an upper casing, a crushing box fixedly connected to the left side of the upper casing, a lower casing fixedly connected to the right side of the crushing box, an inclined plate fixedly connected to the inner side of the upper casing, a cooling assembly provided at the top of the inclined plate, two sets of crushing rollers rotatably connected to the inner side of the crushing box, the two sets of crushing rollers being externally connected to a driving device, a drying assembly fixedly connected to the inner side of the lower casing, a pipe rack fixedly connected to the top of the inner side of the upper casing, a spray pipe fixedly connected to the inner side of the pipe rack, a nozzle device fixedly connected to the bottom of the spray pipe, a centrifugal pump fixedly connected to the rear side of the upper casing, the liquid outlet end of the centrifugal pump penetrating the upper casing and fixedly connected to the spray pipe, a fan device fixedly connected to the left side of the crushing box, a connecting pipe fixedly connected to the air outlet end of the fan device, the connecting pipe penetrating the lower casing to the inner side of the lower casing and fixedly connected to a branch pipe.

[0008] By employing the above technical solution, and by setting up an upper casing, a crushing chamber, and a lower casing, the slag processing is conducted in a relatively enclosed environment. After the slag is fed in through the top right side of the upper casing, it falls onto the cooling assembly and descends along the inclined cooling assembly. During this descent, a centrifugal pump draws external cooling water and evenly sprays it onto the slag surface through spray pipes and nozzles inside the pipe rack to quickly reduce its heat. As the slag moves to the left along the cooling assembly, smaller slag particles pass through the cooling assembly. The components fall onto the inclined plate and along the left side of the inclined plate to the inside of the lower chassis. Larger pieces of slag fall into the crushing box and are crushed into smaller sizes by the crushing rollers driven by the external drive equipment. These smaller pieces then slide down the lower chassis onto the drying components. As the smaller pieces of slag move along the drying components, the blower blows in external airflow and sweeps the slag from the drying components through connecting pipes and branch pipes. Combined with the residual heat of the slag, the sprayed water evaporates quickly, further reducing the temperature of the slag.

[0009] The present invention is further configured such that: the cooling assembly includes an upper frame, a plurality of first spring members are fixedly connected to the top and bottom of the inner side of the upper frame, a mesh frame is fixedly connected between the top first spring members and the bottom first spring members, a screen is fixedly connected to the inner side of the mesh frame, and a pull frame is fixedly connected to the bottom of the screen.

[0010] By adopting the above technical solution, the upper frame is set in conjunction with the first spring to install the mesh frame inside the upper casing, and the mesh frame has a certain displacement space. When the displacement occurs, the first spring stores force and can push the mesh frame to reset by rebound. After the slag is fed in, the slag will fall on the screen and pass through the mesh of the screen to screen out small-sized slag, while large-sized slag can move along the top of the screen. The set pull frame can facilitate the transmission of force to the screen after being subjected to force.

[0011] The present invention is further configured such that: the drying component includes two side plates, a lower sliding plate is fixedly connected between the two side plates, a convex window is fixedly connected to the top of the lower sliding plate, a net is fixedly connected to the inner side of the convex window, and a limiting frame is fixedly connected to the top of the lower sliding plate.

[0012] Using the above technical solution, by setting side plates, the drying components are installed in the lower casing. Small-sized slag and crushed slag directly screened by the cooling components will fall into the lower slide plate and slide down along the lower slide plate. The airflow blown in by the branch pipe will enter the lower casing through the convex window to blow away the slag. The slag is intercepted by the baffle to prevent it from entering the convex window. The setting of the limiting frame is used to transmit the force to the lower slide plate after being subjected to force.

[0013] The present invention is further configured such that: both the upper and lower chassis are rotatably connected to a drive shaft, a hammer seat is fixedly connected to the outer side of the drive shaft, three sets of hammer rods are movably connected to the inner side of the hammer seat, and impact blocks are fixedly connected to the outer sides of both the limiting frame and the pull frame.

[0014] By adopting the above technical solution, a drive shaft is set up so that when it is driven to rotate, the hammer seat outside it will also rotate. The hammer rod inside the hammer seat will stand upright due to the centrifugal tendency during rotation. The hammer rods on the outside of the two drive shafts will strike the two impact blocks respectively, and rotate along the hammer seat during the impact. After missing the position of the impact block, they will stand upright again to continuously apply hammering to the limiting frame and the pull frame. This causes the screen and the slide plate connected to it to vibrate continuously on the inner side of the upper and lower machine boxes through the screen frame and the side plate. At the same time, the slag on the screen frame will be bounced up, avoiding only the top layer of slag being sprayed. Due to the continuous short-term suspension of the slag, its cooling efficiency is also high. Since the whole structure is sealed, no dust will escape to the outside. When the slag on the slide plate is bounced up, it will have more uniform contact with the airflow. When the airflow passes by, it can also accelerate the evaporation of moisture and the cooling effect.

[0015] The present invention is further configured such that: a lower frame is fixedly connected to the front and rear sides of the inner side of the lower chassis; the top and bottom of the two lower frames are respectively located on the outer side of the two side pieces; a plurality of second springs are fixedly connected to the top and bottom of the two side pieces; and the side of the second spring away from the side piece is fixedly connected to the inner side of the lower frame.

[0016] By adopting the above technical solution, a lower frame is set to cooperate with the second spring to install the side plates, so that the entire drying assembly can vibrate along the lower frame and reset through the deformation and rebound of the second spring.

[0017] The present invention is further configured such that: a material hopper is fixedly connected to the right side of the top of the upper chassis, a material distribution shaft is rotatably connected to the inner side of the material hopper, a paddle is fixedly connected to the outer side of the material distribution shaft, a speed reducer is fixedly connected to the front side of the material hopper, and the output end of the speed reducer is fixedly connected to the material distribution shaft.

[0018] By adopting the above technical solution, a large amount of slag can be stored by setting up a hopper. When the distribution shaft is driven to rotate by the reducer, the outer blades will push the slag into the inner side of the upper machine box, so that the slag is kept dynamic and fed into the machine at a uniform speed, which can effectively avoid poor processing effect or blockage.

[0019] The present invention is further configured such that: a servo motor is fixedly connected to the bottom of the inner side of the upper chassis, a drive shaft is fixedly connected to the output end of the servo motor, the outer side of the drive shaft is rotatably connected to the inner side of the upper chassis, and synchronous pulleys are fixedly connected to the input ends of the drive shaft, the material distribution shaft and the reducer, and the synchronous pulleys are connected to each other by synchronous belt drive.

[0020] By adopting the above technical solution, a servo motor is set up to drive the drive shaft to rotate while simultaneously driving the drive shaft, the material distribution shaft, and the reducer to rotate via a synchronous belt pulley. Since the servo motor is installed at the bottom of the inclined plate of the upper chassis, it can avoid contact with slag and contamination while reducing space occupation.

[0021] The present invention is further configured such that: a guide plate is fixedly connected to the inner side of the upper casing, the guide plate is located at the top of the screen, and an integrally formed material-forming plate and a material-distributing plate are fixedly connected to the inner side of the upper casing, the material-distributing plate is located on the left side of the lower slide plate, and the material-forming plate is located at the bottom of the screen.

[0022] Using the above technical solution, by setting a guide plate, after the slag is pushed into the upper chamber by the paddle, it will fall onto the guide plate and slide onto the screen. The material-forming plate is used to guide the large-sized slag into the crushing box, while the small-sized slag will fall into the lower chamber due to the guidance of the material-distributing plate.

[0023] The present invention is further configured such that: a guide bucket is fixedly connected to the top of the crushing box, the top of the guide bucket is fixedly connected to the left side of the material forming plate, and a secondary shell is fixedly connected between the upper and lower machine boxes.

[0024] By adopting the above technical solution, the guide bucket can be set to guide the large-sized slag entering the crushing box, so that it falls between the two crushing rollers. In addition, the material plate can be used to prevent the slag from falling to the outside. The secondary shell can assist in supporting the upper and lower boxes while supporting the structure.

[0025] The present invention is further configured such that: a crossbeam is fixedly connected to the inner side of the sub-shell, an electric cylinder is fixedly connected to the bottom of the crossbeam, a partition is fixedly connected to the telescopic end of the electric cylinder, and an electromagnet device is fixedly connected to the inner side of the partition.

[0026] By adopting the above technical solution, by setting up a crossbeam, the installed electric cylinder will push or pull the partition closer to or away from the drying component when it extends or retracts. When the electromagnet device is started, it can adsorb the metal impurities in the slag, so as to initially classify the slag.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the present invention provides a slag recycling and treatment structure for waste incineration power generation, which has the following beneficial effects: This slag recycling and processing structure for waste incineration power generation uses a drive shaft. When the shaft is driven to rotate, the external hammer base also rotates. The hammer rods inside the hammer base stand upright due to the centrifugal force during rotation. The hammer rods on the outside of the two drive shafts strike two impact blocks respectively, and rotate along the hammer base during the impact. After missing the impact block, they stand upright again to continuously hammer the limiting frame and the pull frame. This causes the screen and the slide plate connected to them to vibrate continuously inside the upper and lower casings through the screen frame and side plates. During the vibration, the slag on the screen frame is bounced up, preventing only the top layer of slag from being sprayed. Due to the continuous short-term suspension of the slag, its cooling efficiency is also high. Since the whole structure is sealed, no dust will escape to the outside. When the slag on the slide plate is bounced up, it will have more uniform contact with the airflow, which can also accelerate the evaporation of moisture and the cooling effect when the airflow passes by.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figure 1-8A slag recycling and processing structure for waste incineration power generation includes an upper casing 1, a crushing box 2 fixedly connected to the left side of the upper casing 1, a lower casing 3 fixedly connected to the right side of the crushing box 2, an inclined plate 4 fixedly connected to the inner side of the upper casing 1, a cooling assembly 5 provided on the top of the inclined plate 4, two sets of crushing rollers 6 rotatably connected to the inner side of the crushing box 2, the two sets of crushing rollers 6 being externally connected to a driving device, a drying assembly 7 fixedly connected to the inner side of the lower casing 3, and a fixed assembly 7 on the top of the inner side of the upper casing 1. A pipe rack 8 is connected, and a spray pipe 9 is fixedly connected to the inner side of the pipe rack 8. A nozzle device is fixedly connected to the bottom of the spray pipe 9. A centrifugal pump 10 is fixedly connected to the rear side of the upper casing 1. The liquid outlet end of the centrifugal pump 10 passes through the upper casing 1 and is fixedly connected to the spray pipe 9. A blower device 11 is fixedly connected to the left side of the crushing box 2. A connecting pipe 12 is fixedly connected to the air outlet end of the blower device 11. The connecting pipe 12 passes through the lower casing 3 to the inner side of the lower casing 3 and is fixedly connected to a branch pipe 13. By setting up an upper casing 1, a crushing box 2, and a lower casing 3, the slag processing is conducted in a relatively enclosed environment. After the slag is fed in through the top right side of the upper casing 1, it falls onto the cooling assembly 5 and descends along the inclined cooling assembly 5. During the descent, the centrifugal pump 10 draws external cooling water and evenly sprays it onto the slag surface through the spray pipes 9 and nozzles inside the pipe rack 8 to quickly reduce its heat. As the slag moves to the left along the cooling assembly 5, smaller slag particles pass through the cooling assembly 5 and fall onto the inclined plate. 4. Larger pieces of slag fall onto the inner side of the lower casing 3 along the left side of the inclined plate 4. Larger pieces of slag fall into the crushing box 2 and are crushed into smaller sizes by the crushing roller 6 driven by the external drive equipment. They then slide down the lower casing 3 onto the drying assembly 7. As the smaller pieces of slag move along the drying assembly 7, the blower device 11 blows in external airflow and sweeps the slag from the drying assembly 7 through the connecting pipe 12 and the branch pipe 13. Combined with the residual heat of the slag, the sprayed water can evaporate quickly, further reducing the temperature of the slag.

[0034] The cooling assembly 5 includes an upper frame 51. Several first spring members 55 are fixedly connected to the top and bottom of the inner side of the upper frame 51. A mesh frame 52 is fixedly connected between the top and bottom first spring members 55. A screen 53 is fixedly connected to the inner side of the mesh frame 52, and a pull bracket 54 is fixedly connected to the bottom of the screen 53. By setting the upper frame 51 in conjunction with the first spring members 55, the mesh frame 52 is installed inside the upper casing 1, allowing the mesh frame 52 a certain displacement space. During displacement, the first spring members 55 store force and can push the mesh frame 52 back to its original position through rebound. After slag is added, the slag falls onto the screen 53, and small-sized slag is sieved through the mesh openings of the screen 53, while larger-sized slag can pass through the screen. The top of 53 moves, and the set bracket 54 facilitates the transmission of force to the screen 53 after being subjected to force. The drying component 7 includes two side plates 71, and a lower slide plate 72 is fixedly connected between the two side plates 71. A convex window 73 is fixedly connected to the top of the lower slide plate 72, and a baffle 74 is fixedly connected to the inner side of the convex window 73. A limiting frame 75 is fixedly connected to the top of the lower slide plate 72. By setting the side plates 71, the drying component 7 is installed in the lower chamber 3. Small-sized slag and crushed slag directly screened by the cooling component 5 will fall into the lower slide plate 72 and slide down along the lower slide plate 72. The airflow blown in by the branch pipe 13 will be introduced into the lower chamber 3 through the convex window 73 to blow away the slag, and the baffle 74 will intercept the slag to prevent it from entering the convex window 73. In section 3, the limiting frame 75 is used to transmit force to the lower slide plate 72 after being subjected to force. Both the upper chassis 1 and the lower chassis 3 are rotatably connected to drive shafts 14. A hammer seat 15 is fixedly connected to the outside of the drive shaft 14, and three sets of hammer rods 16 are movably connected to the inside of the hammer seat 15. Impact blocks 17 are fixedly connected to the outside of both the limiting frame 75 and the pull frame 54. By setting the drive shaft 14, when it is driven to rotate, the hammer seat 15 outside it will also rotate. The hammer rods 16 located inside the hammer seat 15 will stand upright due to the centrifugal force during rotation. The hammer rods 16 outside the two drive shafts 14 respectively strike the two impact blocks 17, and rotate along the hammer seat 15 during impact. After missing the position of the impact block 17, they stand upright again to continuously impact the limiting frame 75 and... The pull frame 54 applies a hammer blow, causing it, along with the connected screen 53 and lower slide plate 72, to continuously vibrate inside the upper casing 1 and lower casing 3 via the screen frame 52 and side plates 71. Simultaneously, the slag on the screen frame 52 is bounced up, preventing only the top layer of slag from being sprayed. Due to the continuous brief suspension of the slag, its cooling efficiency is also high. Because the overall structure is sealed, no dust escapes to the outside. When the slag on the lower slide plate 72 is bounced up, it makes more uniform contact with the airflow, which also accelerates moisture evaporation and cooling effect as the airflow passes through. Lower frames 18 are fixedly connected to the front and rear sides of the inner side of the lower casing 3, with the top and bottom of the two lower frames 18 located on the outer sides of the two side plates 71, respectively.Several second springs 19 are fixedly connected to the top and bottom of both side plates 71. The side of the second spring 19 away from the side plate 71 is fixedly connected to the inner side of the lower frame 18. The lower frame 18 is provided to cooperate with the second springs 19 in installing the side plates 71, so that the entire drying assembly 7 can vibrate along the lower frame 18 and return to its original position through the deformation and rebound of the second springs 19.

[0035] The working principle of this embodiment is as follows: In the closed processing space consisting of the upper casing 1, the crushing box 2, and the lower casing 3, the slag is fed in and falls onto the screen 53 of the inclined cooling component 5 in the upper casing 1. The centrifugal pump 10 draws cooling water and sprays it evenly through the spray pipe 9 and the nozzle to cool it down. The cooling component 5 is suspended and installed by the upper frame 51 and the first spring 55. When the drive shaft 14 rotates, the hammer rod 16 stands upright due to centrifugal force and continuously hits the impact block 17 on the pull frame 54, which drives the screen 53 to vibrate at high frequency, so that the slag continuously bounces up and evenly contacts the sprayed water to improve the cooling efficiency. At the same time, small-diameter slag passes through the screen 53 and slides into the lower casing 3 through the inclined plate 4. Large-diameter slag slides along the screen 53 to the crushing box 2 and is crushed into small-sized particles by the two sets of crushing rollers 6 driven by the external drive equipment before falling into the drying component 7 of the lower casing 3. Small-diameter slag falls onto the lower slide plate 72 of the drying assembly 7 and slides down along the inclined plate 4. The drying assembly 7 is installed through the side plate 71, the lower frame 18 and the second spring 19, and is also driven by the drive shaft 14 and the hammer rod 16. The hammer rod 16 hits the impact block 17 on the limiting frame 75, causing the lower slide plate 72 to vibrate at high frequency. The airflow blown in by the fan device 11 is blown towards the slag through the connecting pipe 12 and the branch pipe 13 from the convex window 73. The vibration causes the slag to bounce up and make full contact with the airflow. Combined with the residual heat of the slag, it accelerates the evaporation of sprayed water and further cools it down, and finally completes the continuous processing of slag, solving problems such as dust emission, uneven cooling or drying, and slag agglomeration.

[0036] Example 2

[0037] refer to Figure 1-7 A slag recycling and processing structure for waste incineration power generation also includes a hopper 20, wherein the hopper 20 is fixedly connected to the right side of the top of the upper casing 1, a distributing shaft 21 is rotatably connected to the inner side of the hopper 20, a paddle 22 is fixedly connected to the outer side of the distributing shaft 21, a reducer 23 is fixedly connected to the front side of the hopper 20, and the output end of the reducer 23 is fixedly connected to the distributing shaft 21. By setting up the hopper 20, a large amount of slag can be stored. When the distributor shaft 21 is driven to rotate by the reducer 23, the outer paddle 22 will push the slag into the inner side of the upper casing 1, so that the slag is kept dynamic and fed into the machine at a uniform speed, which can effectively avoid poor processing effect or blockage.

[0038] A servo motor 24 is fixedly connected to the bottom of the inner side of the upper housing 1. A drive shaft 25 is fixedly connected to the output end of the servo motor 24. The outer side of the drive shaft 25 is rotatably connected to the inner side of the upper housing 1. Synchronous pulleys 26 are fixedly connected to the input ends of the drive shaft 25, the material distribution shaft 21, and the reducer 23. The synchronous pulleys 26 are connected by a synchronous belt drive. By setting the servo motor 24, while driving the drive shaft 25 to rotate, it also drives the drive shaft 25, the material distribution shaft 21, and the reducer 23 to rotate via the synchronous pulleys 26. Machine 24 is installed at the bottom of the inclined plate 4 of the upper casing 1. This reduces space occupation and avoids contamination from contact with slag. A guide plate 27 is fixedly connected to the inside of the upper casing 1. The guide plate 27 is located at the top of the screen 53. An integrally formed material-forming plate 28 and a material-distributing plate 29 are also fixedly connected to the inside of the upper casing 1. The material-distributing plate 29 is located to the left of the lower slide plate 72, and the material-forming plate 28 is located at the bottom of the screen 53. By setting the guide plate 27, after the slag is pushed into the upper casing 1 by the pusher plate 22, it will fall onto the guide plate 27 and slide onto the screen 53. The material-stabilizing plate 28 guides large-sized slag into the crushing box 2, while smaller slag is guided by the material-distributing plate 29 into the lower box 3. A guide hopper 30 is fixedly connected to the top of the crushing box 2, and the top of the guide hopper 30 is fixedly connected to the left side of the material-stabilizing plate 28. A secondary shell 35 is fixedly connected between the upper box 1 and the lower box 3. By setting the guide hopper 30, it is easy to guide large-sized slag entering the crushing box 2, causing it to fall between the two crushing rollers 6, and, in conjunction with the material-stabilizing plate 28, prevents slag from falling to the outside. The sub-shell 35 can assist in supporting the upper casing 1 and the lower casing 3 while also supporting the structure. A crossbeam 31 is fixedly connected to the inner side of the sub-shell 35. An electric cylinder 32 is fixedly connected to the bottom of the crossbeam 31. A partition 33 is fixedly connected to the telescopic end of the electric cylinder 32. An electromagnet device 34 is fixedly connected to the inner side of the partition 33. By setting the crossbeam 31, the installed electric cylinder 32 will push or pull the partition 33 closer to or further away from the drying component 7 when it telescopically extends or retracts. When the electromagnet device 34 is activated, it can adsorb the metal impurities in the slag to initially classify the slag.

[0039] Working principle of this embodiment: The hopper 20 can store a large amount of slag. After the servo motor 24 at the bottom of the upper housing 1 is started, it drives the drive shaft 25 to rotate. Through the transmission action of the synchronous pulley 26 and the synchronous belt, it synchronously drives the distribution shaft 21 and the reducer 23 to operate. The reducer 23 drives the distribution shaft 21 to rotate. The outer paddle 22 evenly and dynamically pushes the slag in the hopper 20 into the upper housing 1, avoiding excessive feeding at one time, which may cause blockage or insufficient processing. The servo motor 24 is installed at the bottom of the inclined plate 4, which can avoid direct contact with the slag and reduce the risk of contamination and damage. The slag fed by the paddle 22 first falls on the guide plate 27 and slides down the screen 5 of the cooling component. 3. After screening by screen 53, large-sized slag slides along the bottom material plate 28 and falls precisely between the two sets of crushing rollers 6 through the guide bucket 30 at the top of the crushing box 2 to complete the crushing. Small-sized slag is guided by the material distribution plate 29 and falls directly into the drying component 7 of the lower casing 3 to achieve separate processing of coarse and fine slag. The sub-shell 35 not only helps to fix the upper casing 1 and the lower casing 3, but also provides installation support for the subsequent sorting components to improve the overall structural stability. At the same time, the crossbeam 31 inside the sub-shell 35 is fixed with an electric cylinder 32. The extension and retraction of the electric cylinder 32 can push the partition 33 and the electromagnet device 34 inside to approach or move away from the drying component 7. After the electromagnet device 34 is activated, it adsorbs metal impurities in the slag.
