Description

Technical Field

[0001] The present invention relates to the technical field of curing devices, and specifically relates to a uniform mixing and curing device for fly ash treatment in a waste incinerator. Background Art

[0002] Waste incineration is a common method for waste treatment. Recycling the heat generated by waste incineration can achieve the purpose of waste resource utilization and can quickly treat domestic waste. However, during the waste incineration process, in addition to generating heat, a large amount of fly ash substances will also be generated. Direct discharge of these substances will cause environmental pollution, so it is necessary to carry out solidification treatment for fly ash. Among them, chelation treatment in the prior art is recognized as the most effective solidification treatment method.

[0003] In the prior solidification device, the stirring efficiency is relatively low during the stirring process of materials, resulting in unstable mixing effects, and there is a large amount of residual materials inside the device after long-term operation, which makes the subsequent cleaning of the device more difficult. Therefore, a new design has been made for this situation. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A uniform mixing and curing device for fly ash treatment in a waste incinerator, including a stirring mechanism. The lower side of the outside of the stirring mechanism is fixedly connected with a support frame body. The upper side of the outside of the stirring mechanism is fixedly connected with an input mechanism. The bottom of the inner wall of the stirring mechanism is rotatably connected with a rotating mechanism. The top of the stirring mechanism is fixedly connected with a first motor. The middle of the bottom of the stirring mechanism is fixedly connected with a second motor. One side of the bottom of the stirring mechanism is fixedly connected with a discharge valve; The stirring mechanism includes a stirring housing. At the top of the inner wall of the stirring housing, a central rotating shaft is rotatably connected. On the outer side of the central rotating shaft, an adapter housing is fixedly connected. During the process of the stirring plate rubbing against the fly ash, the connecting rod rotates on the outer side of the adapter housing, thereby increasing the stirring range by rotation, thus achieving the effect of improving the stirring range, improving the operation efficiency. On the outer side of the adapter housing, a connecting rod is rotatably connected. On the outer side of the connecting rod, a stirring plate is fixedly connected. Fly ash enters the inside of the stirring housing from one side of the input mechanism, and chelating agents, etc. enter the inside of the stirring housing from one side of the top of the stirring housing. The central rotating shaft is controlled by a first motor to rotate, and the central rotating shaft drives the stirring plate to rotate, so that the stirring plate stirs the fly ash and the chelating agent, thereby promoting the mixing of the material and the liquid. By evenly mixing the material and the liquid, the effect of removing heavy metals is achieved, avoiding the potential danger caused by heavy metals and preventing damage to the environment. On both sides of the outside of the central rotating shaft, a friction mechanism is fixedly connected. On one side of the outside of the stirring housing, it is fixedly connected to the outside of the input mechanism. On the side of the outside of the stirring housing far from the input mechanism, a cement pipe is fixedly connected. At the bottom of the inner wall of the stirring housing, it is rotatably connected to the outside of the rotating mechanism. A curing agent such as cement is fed in from one side of the cement pipe. By adding cement, the curing effect is ensured, so that the heavy metals in the fly ash are effectively chelated, avoiding the re-release of heavy metals during the subsequent curing process. The stirred material is discharged outward through the discharge valve, thus facilitating subsequent processing such as fixing the shape.

[0005] Preferably, at the top of the inner wall of the stirring housing, an annular pipeline is fixedly connected. Near one side of the rotating mechanism on the outside of the annular pipeline, holes are opened. At the top of the annular pipeline, an external connecting pipe is fixedly connected. Additives such as chelating agents enter the inside of the annular pipeline from the top of the external connecting pipe, and then the chelating agent sprays liquid into the inside of the stirring housing from the holes at the bottom of the annular pipeline, thereby realizing injecting liquid while stirring, thus promoting the uniform mixing of the material and the liquid, avoiding affecting the subsequent stirring effect. Secondly, by injecting additives such as chelating agents first, the chelation reaction is avoided from being affected by subsequent curing agents.

[0006] Preferably, the friction mechanism includes a connecting bracket. On the side of the connecting bracket away from the central rotating shaft, a connecting shaft is rotatably connected. A rhombic block is fixedly connected to the outer side of the connecting shaft. During the stirring process of the stirring mechanism, it is easy for the material to adhere to the inner wall of the stirring housing. On the one hand, the adhesion of the material affects the subsequent stirring effect. On the other hand, to prevent the material from adhering for a long time and causing corrosion or pollution to the equipment, the connecting bracket rotates along the outer side of the central rotating shaft, causing the rhombic block to rub against the inner wall of the stirring housing, thereby achieving the effect of scraping the material, peeling off the material adsorbed on the inner wall of the equipment, and stirring the remaining stagnant material in the operation, saving resource waste and reducing material residue, and reducing the difficulty of cleaning the equipment subsequently. A friction block is fixedly connected to the outer side of the rhombic block. The friction block is made of silicone material, which plays a certain buffering effect during the friction against the inner wall of the equipment, reducing the wear of the components on the inner wall of the equipment and preventing damage to the equipment after long-term operation, thereby prolonging the service life of the components.

[0007] Preferably, the rotating mechanism includes an axial block. An external column is fixedly connected to the outer side of the axial block. A rotating paddle is fixedly connected to the outer side of the external column. The second motor controls the rotation of the axial block, causing the rotating paddle to stir the bottom material, thereby affecting the mixing effect at the bottom of the equipment. In this way, the material and liquid are evenly mixed, strengthening the contact between the fly ash and other materials, and preventing the material from precipitating and accumulating. Fly ash and some other materials are prone to precipitate and accumulate at the bottom of the equipment in a static state, affecting the mixing effect and the normal operation of the equipment. The bottom stirring can continuously turn over the bottom material, keeping it in a dynamic suspension state, preventing precipitation and accumulation, ensuring the uniform distribution of the material in the equipment, improving the mixing efficiency and quality, and increasing the reaction speed. A cleaning mechanism is fixedly connected to the side of the axial block away from the rotating paddle.

[0008] Preferably, the cleaning mechanism includes a cleaning housing. An adapter shaft is fixedly connected to the inner side of the cleaning housing. A cleaning block is rotatably connected to the outer side of the adapter shaft. The cleaning housing rotates along with the axial block, causing the cleaning block to rub against the bottom of the inner wall of the equipment, thereby achieving the effect of cleaning the material and promoting the movement of the material towards the discharge valve side, thereby increasing the discharge speed of the material and improving the operation efficiency. Diagonal plates are fixedly connected to both sides of the outer part of the cleaning housing. During the rotation of the cleaning housing, the diagonal plates scrape the bottom of the inner wall of the equipment, thereby achieving the effect of further improving the cleaning of the material particles and preventing the material particles from caking and remaining on the inner wall of the equipment, improving the cleaning effect.

[0009] Preferably, the input mechanism includes an input pipeline. Fly ash enters the inside of the stirring housing through the input pipeline. After long-term transportation of fly ash, it is easy for fly ash to accumulate inside the pipeline, which will affect the transportation efficiency of materials. On both sides of the inner wall of the input pipeline, there are fixedly connected fixing frames. Between the opposite surfaces of the fixing frames, there is a rotatably connected rotating shaft. On the outer side of the rotating shaft away from the stirring housing, there is a fixedly connected driven gear. The outside of the driven gear is rotatably connected with a connecting belt. On the outer side of the connecting belt away from the driven gear, there is a rotatably connected driving gear. On the outer side of the driving gear, there is a fixedly connected third motor. The third motor drives the driving gear to rotate. The driving gear drives the driven gear to rotate through the connecting belt, driving the rotating mechanism to rub against the inner wall of the pipeline, so as to clean the dust on the inner wall, making the dust peel off and enter the inside of the stirring housing. Considering that fly ash may have a certain humidity during storage and transportation, which may cause dust to adsorb on the inner wall of the pipeline, preventing dust caking and affecting the transportation effect. On the outer side of the rotating shaft, there is a fixedly connected rotating mechanism, and on the outer side of the input pipeline, there is a fixedly connected drying mechanism.

[0010] Preferably, the rotating mechanism includes a rotating bracket. On the outer side of the rotating bracket away from the rotating shaft, there is a fixedly connected receiving shaft. On the outer side of the receiving shaft, there is a rotatably connected triangular prism. The rotating shaft drives the rotating bracket to rotate, so that the triangular prism drives the cylindrical block to rub against the inner wall of the pipeline, so as to clean the inner wall by friction, reducing the adsorption of dust and impurities, and preventing dust from caking on the inner wall of the pipeline. On one side of the outer side of the triangular prism, there is a cylindrical surface cut. Inside the cylindrical surface cut, there is a rotatably connected cylindrical block. On the outer side of the cylindrical block, there is a square cut. By opening the square cut and designing the texture through the groove, the friction performance on the inner wall of the pipeline is increased through the texture structure, further improving the cleaning effect of dust and improving the operation efficiency. On the outer side of the triangular prism, there is a fixedly connected wiping mechanism.

[0011] Preferably, the wiping mechanism includes a telescopic rod. On one side of the outer side of the telescopic rod, there is a fixedly connected friction plate. During the friction rotation of the cylindrical block and the inner wall of the pipeline, the cylindrical block and the friction plate are frictionally adapted, so as to clean the dust or materials on the surface of the component, preventing excessive adsorption of dust on the surface of the component and avoiding affecting the subsequent friction effect. On the outer side of the telescopic rod, there is a sleeved spring strip. During the friction with the cylindrical block, it is easy for the friction plate to generate a vibration amplitude. The spring strip plays a role in shock absorption and buffering, reducing the amplitude of the component, improving the stability of the component, buffering the wear effect between components, and thus prolonging the service life of the component.

[0012] Preferably, the drying mechanism includes a dryer. During the storage and transportation of fly ash, it is easy for there to be a certain humidity inside the fly ash or it is affected by the external environment. Therefore, when the fly ash is transported inside the input pipeline, it is easy for the fly ash to adhere to the inner wall of the pipeline, thereby affecting the subsequent transportation effect of the material. The dryer generates hot air flow, and the hot air flow flows from the air inlet pipe to the exhaust pipe to dry the inner wall of the pipeline, thereby reducing the moisture inside the material and maintaining dryness during the transportation process. The bottom of the dryer is fixedly connected to an air inlet pipe, and the outer side of the air inlet pipe away from the dryer is fixedly connected to an exhaust pipe. The lower side of the inner wall of the exhaust pipe is fixedly connected to a docking plate to limit the entry of dust and avoid clogging of components. The inner wall of the exhaust pipe near the docking plate is fixedly connected to a connecting support rod, and the outer side of the connecting support rod is rotatably connected to a blade block. The blade block is impacted by the air flow, and the blade block rotates to block the entry of impurities and keep the air flow inside the device unobstructed.

[0013] The present invention provides a uniform mixing and solidifying device for fly ash treatment in a waste incinerator. It has the following beneficial effects: First, in this uniform mixing and solidifying device for fly ash treatment in a waste incinerator, through the design of the stirring mechanism, fly ash enters the inside of the stirring housing from one side of the input mechanism, and chelating agents, etc. enter the inside of the stirring housing from one side of the top of the stirring housing. The central rotating shaft is rotated by the first motor, and the central rotating shaft drives the stirring plate to rotate, so that the stirring plate stirs the fly ash and the chelating agent, thereby promoting the mixing of the material and the liquid. By evenly mixing the material and the liquid, the effect of removing heavy metals is achieved, avoiding the potential danger caused by heavy metals and preventing damage to the environment. During the process of the stirring plate stirring and rubbing against the fly ash, the connecting rod rotates outside the connecting housing, thereby achieving the effect of increasing the stirring range by rotation, so as to improve the stirring range and improve the operation efficiency. Then, curing agents such as cement are fed in from one side of the cement pipe. By adding cement, the curing effect is ensured, so that the heavy metals in the fly ash are effectively chelated, and the release of heavy metals during the subsequent solidification process is avoided. The stirred material is discharged outward through the discharge valve, so as to facilitate subsequent treatment such as forming a fixed shape.

[0014] Second, for the uniform mixing and solidifying device for fly ash treatment of this waste incinerator, through the design of the friction mechanism, during the stirring process of the stirring mechanism, it is easy for materials to adhere to the inner wall of the stirring shell. On the one hand, the adhesion of materials affects the subsequent stirring effect. On the other hand, to prevent the equipment from being corroded or polluted due to the long-term adhesion of materials, the connecting bracket rotates along the outside of the central rotating shaft, causing the rhombic block to rub against the inner wall of the stirring shell, thereby achieving the effect of scraping the materials, peeling off the materials adsorbed on the inner wall of the equipment, and stirring the remaining stagnant materials in the operation, saving resource waste and reducing material residue, and reducing the cleaning difficulty of the equipment in the future. The friction block is made of silica gel material, which has a certain buffering effect during the friction against the inner wall of the equipment, reducing the wear of components on the inner wall of the equipment and preventing damage to the equipment after long-term operation, thus prolonging the service life of the components.

[0015] Third, for the uniform mixing and solidifying device for fly ash treatment of this waste incinerator, through the design of the rotating mechanism, the shaft-shaped block is controlled by the second motor to rotate, causing the rotating paddle to stir the bottom materials, which may affect the mixing effect at the bottom of the equipment. Thus, the materials and liquid are uniformly mixed, strengthening the contact between fly ash and other materials, and preventing the precipitation and accumulation of materials. Fly ash and some other materials are prone to precipitate and accumulate at the bottom of the equipment in a static state, affecting the mixing effect and the normal operation of the equipment. The bottom stirring can continuously turn over the bottom materials, keeping them in a dynamic suspension state, preventing precipitation and accumulation, ensuring the uniform distribution of materials in the equipment, improving the mixing efficiency and quality, and increasing the reaction speed.

[0016] Fourth, for the uniform mixing and solidifying device for fly ash treatment of this waste incinerator, through the design of the input mechanism, fly ash enters the inside of the stirring shell from the input pipeline. After long-term transportation of fly ash, it is easy for fly ash to accumulate inside the pipeline, which may affect the transportation efficiency of the materials. The third motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate through the connecting belt, driving the rotating mechanism to rub against the inner wall of the pipeline, thereby achieving the effect of cleaning the dust on the inner wall, making the dust peel off and enter the inside of the stirring shell. Considering that fly ash may have a certain humidity during storage and transportation, which may cause dust to adsorb on the inner wall of the pipeline, preventing dust caking and affecting the transportation effect.

[0017] V. The uniform mixing and solidification device for fly ash treatment of this waste incinerator. Through the design of the drying mechanism, during the storage and transportation of fly ash, there is likely to be a certain humidity inside the fly ash, or it is affected by the external environment. Therefore, when the fly ash is transported inside the input pipeline, it is easy for the fly ash to adhere to the inner wall of the pipeline, thus affecting the subsequent transportation effect of the material. By generating hot air flow with the dryer, the hot air flow flows from the air delivery pipe to the exhaust pipe to dry the inner wall of the pipeline, thereby reducing the moisture inside the material and maintaining dryness during the transportation process. The dust is restricted from entering through the docking plate to avoid clogging the components. Secondly, the vane blocks are impacted by the air flow, and the vane blocks rotate to block the impurities from entering and keep the air flow inside the equipment unobstructed.

[0020] 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.

[0021] The first embodiment is as Figures 1 to 4 shown. The present invention provides a technical solution: a uniform mixing and solidifying device for treating fly ash from a waste incinerator, including a stirring mechanism 1. The lower side of the outside of the stirring mechanism 1 is fixedly connected with a support frame body 4. The upper side of the outside of the stirring mechanism 1 is fixedly connected with an input mechanism 3. The bottom of the inner wall of the stirring mechanism 1 is rotatably connected with a rotating mechanism 2. The top of the stirring mechanism 1 is fixedly connected with a first motor 5. The middle of the bottom of the stirring mechanism 1 is fixedly connected with a second motor 6. One side of the bottom of the stirring mechanism 1 is fixedly connected with a discharge valve 7; The stirring mechanism 1 includes a stirring housing 11. At the top of the inner wall of the stirring housing 11, a central rotating shaft 12 is rotatably connected. On the outer side of the central rotating shaft 12, an adapter housing 13 is fixedly connected. On the outer side of the adapter housing 13, a connecting rod 15 is rotatably connected. On the outer side of the connecting rod 15, a stirring plate 16 is fixedly connected. On both sides of the outside of the central rotating shaft 12, a friction mechanism 18 is fixedly connected. On one side of the outside of the stirring housing 11, it is fixedly connected to the outside of the input mechanism 3. On the side of the stirring housing 11 away from the input mechanism 3, a cement pipe 19 is fixedly connected. At the bottom of the inner wall of the stirring housing 11, it is rotatably connected to the outside of the rotating mechanism 2. Fly ash enters the inside of the stirring housing 11 from one side of the input mechanism 3, and chelating agents and the like enter the inside of the stirring housing 11 from one side of the top of the stirring housing 11. By controlling the rotation of the central rotating shaft 12 with the first motor 5, the central rotating shaft 12 drives the stirring plate 16 to rotate, so that the stirring plate 16 stirs the fly ash and the chelating agent, thereby promoting the mixing of the material and the liquid. By evenly mixing the material and the liquid, the effect of removing heavy metals is achieved, avoiding the potential danger caused by heavy metals and preventing damage to the environment. During the process of the stirring plate 16 stirring and rubbing against the fly ash, the connecting rod 15 rotates on the outer side of the adapter housing 13, thereby achieving the effect of increasing the stirring range by rotation, so as to improve the stirring range and improve the operation efficiency. Then, a curing agent such as cement is fed in from one side of the cement pipe 19. By adding cement, the curing effect is ensured, so that the heavy metals in the fly ash are effectively chelated, avoiding the re-release of heavy metals during the subsequent curing process. The stirred material is discharged outward from the discharge valve 7, so as to facilitate subsequent processing such as fixing the shape.

[0022] At the top of the inner wall of the stirring housing 11, an annular pipe 17 is fixedly connected. On the side of the outside of the annular pipe 17 close to the rotating mechanism 2, holes are opened. On the top of the annular pipe 17, an external connection pipe 14 is fixedly connected. Chelating agents and other additives enter the inside of the annular pipe 17 from the top of the external connection pipe 14, and then the chelating agent sprays the liquid into the inside of the stirring housing 11 from the holes at the bottom of the annular pipe 17, thereby realizing the injection of the liquid while stirring, so as to promote the uniform mixing of the material and the liquid, avoiding affecting the subsequent stirring effect. Secondly, by injecting chelating agents and other additives first, the chelation reaction is avoided from being affected by the subsequent curing agent.

[0023] The friction mechanism 18 includes a connecting bracket 181. On the side of the outer part of the connecting bracket 181 away from the central rotating shaft 12, a connecting shaft 182 is rotatably connected. On the outer side of the connecting shaft 182, a rhombic block 183 is fixedly connected. On the outer side of the rhombic block 183, a friction block 184 is fixedly connected. During the stirring process of the stirring mechanism 1, it is easy for the material to adhere to the inner wall of the stirring housing 11. On the one hand, the adhesion of the material affects the subsequent stirring effect. On the other hand, to prevent the material from adhering for a long time and causing corrosion or pollution to the equipment, the connecting bracket 181 rotates along the outer side of the central rotating shaft 12, so that the rhombic block 183 rubs against the inner wall of the stirring housing 11, thereby achieving the effect of scraping the material, peeling off the material adsorbed on the inner wall of the equipment, and mixing the remaining stagnant material in the stirring operation, saving resource waste, reducing material residue, and reducing the cleaning difficulty of the equipment in the future. The friction block 184 is made of silica gel material, which plays a certain buffering effect during the friction against the inner wall of the equipment, reduces the wear of the parts on the inner wall of the equipment, prevents damage to the equipment after long-term operation, and thus prolongs the service life of the parts.

[0024] Second embodiment, on the basis of the first embodiment, please refer to Figures 5 to 6 As shown, the rotating mechanism 2 includes an axial block 21. On the outer side of the axial block 21, an external connecting column 22 is fixedly connected. On the outer side of the external connecting column 22, a rotating paddle 23 is fixedly connected. On the side of the outer part of the axial block 21 away from the rotating paddle 23, a cleaning mechanism 24 is fixedly connected. The second motor 6 controls the axial block 21 to rotate, so that the rotating paddle 23 stirs the bottom material, which affects the mixing effect at the bottom of the equipment. In this way, the material and liquid are evenly mixed, strengthening the contact between the fly ash and other materials, preventing the material from precipitating and accumulating. Fly ash and some other materials are prone to precipitate and accumulate at the bottom of the equipment in a static state, affecting the mixing effect and the normal operation of the equipment. The bottom stirring can continuously turn over the bottom material, making it in a dynamic suspension state, preventing precipitation and accumulation, ensuring the uniform distribution of the material in the equipment, improving the mixing efficiency and quality, and increasing the reaction speed.

[0025] The cleaning mechanism 24 includes a cleaning housing 241. On the inner side of the cleaning housing 241, a connecting shaft 242 is fixedly connected. On the outer side of the connecting shaft 242, a cleaning block 243 is rotatably connected. On both sides of the outer part of the cleaning housing 241, bevel plates 244 are fixedly connected. The cleaning housing 241 rotates along with the axial block 21, so that the cleaning block 243 rubs against the bottom of the inner wall of the equipment, thereby achieving the effect of cleaning the material, promoting the material to move towards the discharge valve 7, thereby increasing the discharge speed of the material and improving the operation efficiency. Secondly, during the rotation of the cleaning housing 241, the bevel plates 244 rub against the bottom of the inner wall of the equipment, thereby achieving the effect of further improving the cleaning of material particles, preventing the material particles from caking and remaining on the inner wall of the equipment, and improving the cleaning effect.

[0026] Third embodiment, on the basis of the first and second embodiments, please refer toFigures 7 to 10 As shown in the figure, the input mechanism 3 includes an input pipeline 31. On both sides of the inner wall of the input pipeline 31, there are fixedly connected fixing frames 32. Between the opposite surfaces of the fixing frames 32, there is a rotatably connected rotating shaft 33. On the outer side of the rotating shaft 33 away from the stirring housing 11, there is a fixedly connected driven gear 34. On the outer side of the driven gear 34, there is a rotatably connected connecting belt 35. On the outer side of the connecting belt 35 away from the driven gear 34, there is a rotatably connected driving gear 36. On the outer side of the driving gear 36, there is a fixedly connected third motor 37. On the outer side of the rotating shaft 33, there is a fixedly connected rotating mechanism 38. On the outer side of the input pipeline 31, there is a fixedly connected drying mechanism 39. Fly ash enters the interior of the stirring housing 11 from the input pipeline 31. After long-term transportation of fly ash, it is easy to cause fly ash to accumulate inside the pipeline, thus affecting the transportation efficiency of the material. By driving the driving gear 36 to rotate through the third motor 37, the driving gear 36 drives the driven gear 34 to rotate through the connecting belt 35, driving the rotating mechanism 38 to rub the inner wall of the pipeline, so as to clean the dust on the inner wall, making the dust peel off and enter the interior of the stirring housing 11. Considering that fly ash may have a certain humidity during storage and transportation, which may cause dust to adsorb on the inner wall of the pipeline, preventing dust caking and thus affecting the transportation effect.

[0027] The rotating mechanism 38 includes a rotating bracket 381. On the outer side of the rotating bracket 381 away from the rotating shaft 33, there is a fixedly connected receiving shaft 382. On the outer side of the receiving shaft 382, there is a rotatably connected triangular prism 383. On the outer side of the triangular prism 383, there is a cylindrical surface cut 384. On the inner side of the cylindrical surface cut 384, there is a rotatably connected cylindrical block 385. On the outer side of the cylindrical block 385, there is a square cut 386. On the outer side of the triangular prism 383, there is a fixedly connected wiping mechanism 387. By driving the rotating bracket 381 to rotate through the rotating shaft 33, the triangular prism 383 drives the cylindrical block 385 to rub the inner wall of the pipeline, so as to clean the inner wall by friction, thereby reducing the adsorption of dust and impurities and preventing dust from caking on the inner wall of the pipeline. By opening the square cut 386 and designing the texture through the groove, the friction performance on the inner wall of the pipeline is increased through the texture structure, thereby further improving the cleaning effect on dust and improving the operation efficiency.

[0028] The wiping mechanism 387 includes a telescopic rod 3871. One side outside the telescopic rod 3871 is fixedly connected with a friction plate 3873, and a spring strip 3872 is sleeved outside the telescopic rod 3871. During the friction rotation of the cylindrical block 385 and the inner wall of the pipeline, the cylindrical block 385 is frictionally adapted to the friction plate 3873, so as to achieve the effect of cleaning the dust or materials on the surface of the component, prevent excessive adsorption of dust on the surface of the component, and avoid affecting the subsequent friction effect. During the friction with the cylindrical block 385, it is easy to cause the friction plate 3873 to generate a vibration amplitude. The spring strip 3872 plays a role in shock absorption and buffering, reduces the amplitude of the component, improves the stability of the component, buffers the wear effect between components, and thus prolongs the service life of the component.

[0029] The drying mechanism 39 includes a dryer 391. The bottom of the dryer 391 is fixedly connected with an air delivery pipe 392. One side of the air delivery pipe 392 far from the dryer 391 is fixedly connected with an exhaust pipe 393. The lower side of the inner wall of the exhaust pipe 393 is fixedly connected with a docking plate 394. One side of the inner wall of the exhaust pipe 393 close to the docking plate 394 is fixedly connected with a connecting support rod 395. The outside of the connecting support rod 395 is rotatably connected with a blade block 396. During the storage and transportation of fly ash, it is easy to cause a certain humidity inside the fly ash or be affected by the external environment. Therefore, when the fly ash is transported inside the input pipeline 31, it is easy to cause the fly ash to adhere to the inner wall of the pipeline, thus affecting the subsequent transportation effect of the material. The dryer 391 generates hot air flow, and the hot air flow flows from the air delivery pipe 392 to the exhaust pipe 393, so as to dry the inner wall of the pipeline, thereby reducing the moisture inside the material and maintaining the dryness during transportation. The docking plate 394 restricts the entry of dust to avoid blocking the components. Secondly, the air flow impacts the blade block 396, and the blade block 396 rotates to block the entry of impurities and keep the air flow inside the equipment smooth.

[0030] During use, fly ash enters the interior of the stirring housing 11 from one side of the input mechanism 3, and additives such as chelating agents enter the interior of the stirring housing 11 from the top of the external connection pipe 14. The method of adding fly ash, chelating agents, and then solidifying agents such as cement is adopted, so that the stirring mechanism 1 stirs the materials. The first motor 5 controls the central rotating shaft 12 to drive the stirring plate 16 to stir the materials, thereby promoting the mixing of solid and liquid, removing heavy metals. The chelating agent can react with heavy metals to form stable chelates, thereby separating heavy metals from fly ash or reducing their mobility and bioavailability in the environment. Stirring fly ash and chelating agents first can allow the chelating agent to fully contact and react with heavy metals in fly ash, improve the removal effect of heavy metals, and improve the subsequent treatment effect. After chelation treatment, the properties of fly ash will change to a certain extent, which is beneficial to subsequent solidification treatment. Then, solidifying agents such as cement enter the interior of the stirring housing 11 from one side of the cement pipe 19. Adding cement later avoids interfering with the chelation reaction. The chelation reaction between the chelating agent and heavy metals in fly ash needs to be carried out under specific conditions to ensure that the reaction is sufficient and stable. If cement is added first, the components in the cement may react with the chelating agent, or change the pH value, ion concentration, etc. of the reaction system, thereby interfering with the chelation of the chelating agent and heavy metals and reducing the removal effect of heavy metals. To ensure the solidification effect, as a solidifying agent, the role of cement is to solidify the fly ash after chelation treatment into a stable solidified body, fix heavy metals in it, further reduce the leaching risk of heavy metals, and improve the long-term stability and safety of the solidified body, so as to facilitate subsequent fixing and shaping. During the operation of the stirring mechanism 1, the second motor 6 controls the rotation mechanism 2 to rotate, promoting the uniform mixing of materials, strengthening the contact between fly ash and other materials, avoiding material stratification or local uneven mixing, ensuring that the proportions of all materials in the entire reaction system are uniform, providing a good basis for subsequent chelation reaction and solidification reaction, preventing material precipitation and accumulation, and improving the reaction efficiency. Finally, the materials are discharged outward through the discharge valve 7, facilitating subsequent fixing and shaping.
