Description

Technical Field

[0001] The invention relates to the technical field of resource utilization and disposal of waste incineration fly ash, and in particular to a resource utilization and disposal device for domestic waste incineration fly ash. Background Art

[0002] Usually, fly ash generated by the incineration of domestic waste needs to be collected for recycling. Since the fly ash from the incineration of domestic waste is rich in heavy metals and soluble chloride salts, it needs to be stabilized and solidified before resource utilization. The incineration fly ash needs to be injected into a mixing container and mixed with a solidifying agent to solidify the incineration fly ash so that the incineration fly ash can be recycled and used as building materials. However, traditional domestic waste incineration fly ash resource utilization and disposal devices still have problems that need to be solved.

[0003] For example, existing technologies usually use a method of directly stirring a solidifying agent to treat fly ash, but the soluble chloride salts remaining in the fly ash are easy to react with the solidifying agent, reducing the strength of the solidified body and increasing the risk of heavy metal leaching. Some technologies attempt to clean and remove the chloride salts, but the rough water injection causes the fly ash to agglomerate or release heat when it comes into contact with water, which directly affects the subsequent solidification effect and disposal safety.

At the same time, it is necessary to fill the cylinder body 1 with a curing agent through the filling cylinder 19, including but not limited to polyacrylate solution, so that the incineration fly ash and the curing agent are stirred and mixed, so that the incineration fly ash reacts to achieve solidification treatment. After the solidification treatment of the incineration fly ash is completed, the staff needs to control the electric rod 6 to extend, so that the electric rod 6 uses the telescopic end to push the sector plate 3 through the connecting plate 4. At the same time, the fixed end of the electric rod 6 will rotate under the support of the cylinder body 1, and the telescopic end of the electric rod 6 will rotate simultaneously under the support of the connecting plate 4. Furthermore, the connecting plate 4 can rotate counterclockwise under the support of the rotating rod 5, and then the connecting plate 4 drives the sector plate 3 to move out from below the cylinder body 1, and then opens the discharge port, so that the solidified incineration fly ash in the cylinder body 1 can be discharged and collected for resource utilization.

[0021] In the actual application of this embodiment, the staff needs to place the cylinder body 1 supported by the support frame 2 at the working site, and rotate the cover 20 to open the opening of the filling cylinder 19 under the support of the end cover 7 to facilitate the filling of incineration fly ash. When the incineration fly ash falls into the cylinder body 1, the staff needs to control the motor 9 to start, so that the motor 9 drives the transmission rod 10 to rotate through the transmission 8, so that the transmission rod 10 can drive the bracket 11 and the stirring rod 12 to rotate together, so that the stirring rod 13 can use the rotational power to stir the incineration fly ash. At the same time, it is necessary to fill the cylinder body 1 with a curing agent through the filling cylinder 19, including but not limited to polyacrylate solution, so that the incineration fly ash and the curing agent are stirred and mixed, so that the incineration fly ash reacts to achieve solidification treatment. After the solidification treatment of the incineration fly ash is completed, the staff needs to control the electric rod 6 to extend, so that the electric rod 6 uses the telescopic end to push the sector plate 3 through the connecting plate 4. At the same time, the fixed end of the electric rod 6 will rotate under the support of the cylinder body 1, and the telescopic end of the electric rod 6 will rotate simultaneously under the support of the connecting plate 4. Furthermore, the connecting plate 4 can rotate counterclockwise under the support of the rotating rod 5, and then the connecting plate 4 drives the sector plate 3 to move out from below the cylinder body 1, and then opens the discharge port, so that the solidified incineration fly ash in the cylinder body 1 can be discharged and collected for resource utilization.

[0022] As a preferred embodiment of the present invention, the pushing member includes: A bracket 11, fixed on the outer side of the transmission rod 10 and located inside the cylinder 1; A rotating rod 16, symmetrically penetrating through the bracket 11 and fixedly connected to the stirring rod 18; Two arc-shaped rubber blocks 26, symmetrically fixed on the bracket 11.

[0023] Specifically, a support cylinder 51 is fixed at the bottom end of the transmission 8, and the support cylinder 51 is located inside the end cover 7. A fixed gear 15 is fixed on the outer side of the support cylinder 51. A moving gear 17 is fixed on the outer side of the rotating rod 16, and the moving gear 17 meshes with the fixed gear 15. The rotating rod 16 is fixedly connected to the stirring rod 18 and can drive the stirring rod 18 to rotate together. The transmission rod 10 can provide support for the bracket 11. The arc-shaped rubber block 26 can use the frictional force to push the rubber wheel 29 in contact with it to rotate under the support of the bracket 11.

[0024] The stirring and shoveling member includes: Two stirring rods 12, symmetrically penetrating through the bracket 11 and intersecting with the rotating rod 16; A stirring plate 13, fixed at the bottom end of one of the stirring rods 12; A shoveling plate 14, fixed at the bottom end of the other stirring rod 12.

[0025] Specifically, the bracket 11 can provide stable support for the stirring rods 12. The stirring rods 12 can provide stable support for the stirring plate 13 and the shoveling plate 14. The stirring plate 13 can rotate together with the bracket 11 under the drive of the stirring rod 12 and participate in the work of stirring the fly ash during the rotation process. At the same time, the shoveling plate 14 will rotate together with the bracket 11 under the support of the other stirring rod 12 and shovel up the fly ash on the inner bottom wall of the cylinder 1 during the rotation process by using the inclination angle and the rotation power.

[0026] In the actual application process of this embodiment, when the motor 9 starts and drives the transmission rod 10 to rotate through the transmission 8, the transmission rod 10 will drive the bracket 11 to rotate together, so that the bracket 11 can drive the rotating rod 16 and the stirring rod 18 to rotate together. At the same time, the rotating rod 16 will use the rotating power to drive the moving gear 17 to rotate together with the transmission rod 10, and the moving gear 17 will roll along the outside of the fixed gear 15 by using the meshing action with the fixed gear 15 during the rotation process. Thus, the moving gear 17 can drive the rotating rod 16 under the action of the fixed gear 15 to rotate under the support of the bracket 11. Furthermore, the rotating rod 16 can drive the stirring rod 18 to rotate together under the support of the bracket 11. Therefore, the stirring rod 18 can rotate around the transmission rod 10 as the center while rotating on its own axis, improving the stirring efficiency and effect. At the same time, the bracket 11 will drive the scraping plate 14 and the stirring plate 13 to rotate together with the transmission rod 10 through the stirring rod 12, so that the stirring plate 13 can stir the incineration fly ash during the rotation process. At the same time, the scraping plate 14 will rotate clockwise together with the stirring rod 12 under the drive of the bracket 11, so that the scraping plate 14 can shovel up the incineration fly ash near the bottom wall of the cylinder body 1 by using its own inclination angle during the rotation process. Through the above working process, the stirring dead zone of the incineration fly ash can be greatly reduced, and the fly ash can be prevented from rotating at the same speed as the stirring rod 12, and the effect and efficiency of stirring and mixing can be improved.

The inclined ring support 23 can provide support for the solenoid valve 25. The inclined ring support 23 has an inclined angle and can provide an inclined guide for the fly ash, so that the fly ash can conveniently fall into the solenoid valve 25.

[0032] Specifically, the shaft seals 27 can play a sealing role between the inclined cylinder 22 and the spiral pipes 28 and can provide rotational support for the spiral pipes 28. The spiral pipes 28 can provide stable support for the rubber wheels 29 and can stably support the disturbing plates 30. The rubber wheels 29 can use external force to push the spiral pipes 28 to rotate under the support of the shaft seals 27, so that the spiral pipes 28 can drive the disturbing plates 30 to rotate together in the cleaning space, and then the disturbing plates 30 can use the rotational power to disturb the fly ash in the cleaning space.

[0033] The inclined disturbing parts include: The first inclined wheel 31 is fixed on the outer side of the spiral pipe 28 and has a first inclined surface; The support columns 32, there are multiple of them, and they are uniformly fixed on the outer side of the ring cylinder 21; The support rods 33, there are multiple of them, and one ends of them are respectively rotationally connected to the support columns 32; The second inclined wheel 34 is fixed at the other end of the support rod 33 and has a second inclined surface and is matched with the first inclined surface of the first inclined wheel 31.

Then, the staff needs to start the motor 9, so that the motor 9 drives the bracket 11 to rotate clockwise through the transmission 8 and the transmission rod 10, and then the bracket 11 drives the arc rubber block 26 to rotate together, so that the arc rubber block 26 uses the rotational power and friction to intermittently push the rubber wheel 29 as it rotates. When the rubber wheel 29 contacts the arc rubber block 26, it is pushed by the arc rubber block 26 using the rotational power, so that the rubber wheel 29 can drive the rotating tube 28 to rotate together, and then the rotating tube 28 can drive the first inclined wheel 31 and the baffle 30 to rotate together using the rotational power. At the same time, the first inclined wheel 31 will use the rotational power and friction to push the second inclined wheel 34 to rotate, so that the second inclined wheel 34 can drive the disturbance plate 35 to rotate together through the support rod 33, and the cleaning space can provide a storage support space for water. Thus, the disturbance plate 35 and the baffle 30 push the water and fly ash in the cleaning space to be mixed and disturbed during rotation, and then use the push of the water and the disturbance plate 35 and the baffle 30 to clean the fly ash to remove soluble chlorides and avoid chloride ions interfering with the subsequent chelation and solidification reaction.

The sealing rings 39 are elastic and can deform under the action of external force and can rebound by the rebounding force.

The outer ring pipe 49 can provide support for the discharge pipe 40. The outer ring pipe 49, the inner ring pipe 37, the rotating pipe 28, the connecting pipe 38, the L-shaped pipe 36 and the drain pipe 50 can provide a flow channel for water or steam.

[0039] The rotating and discharging member includes: A plurality of discharge pipes 40 are symmetrically arranged through the rotating pipe 28; A piston 44 is movably arranged in the discharge pipe 40; A circular ring groove 45 is formed on the outer side of the piston 44; A rubber ring 46 is arranged inside the circular ring groove 45 and is in fit with the inner wall of the discharge pipe 40; An auxiliary part is arranged on the outer side of the rotating pipe 28.

[0040] Specifically, the discharge pipe 40 can provide a discharge channel for the water in the rotating pipe 28, and can provide a moving space and guidance for the piston 44 under the support of the rotating pipe 28. The piston 44 can provide a space for forming the circular ring groove 45. The circular ring groove 45 can provide a clamping space for the rubber ring 46 and can provide rotational positioning for the rubber ring 46. The rubber ring 46 is elastic and can be in fit with the discharge pipe 40 to play a sealing role.

[0041] The auxiliary part includes: A plurality of L-shaped plates 41 are symmetrically fixed on the outer side of the rotating pipe 28 and extend to one end of the discharge pipe 40 away from the rotating pipe 28; A T-shaped rod 42 is movably arranged through the L-shaped plate 41, and one end of the T-shaped rod 42 is fixedly connected with the piston 44; A spring 43 is sleeved outside the T-shaped rod 42 and is located between the L-shaped plate 41 and the piston 44.

[0042] Specifically, one side of the outer ring pipe 49 is connected with a drain pipe 50 in a penetrating manner. The L-shaped plate 41 can provide a penetrating channel and a guiding function for the T-shaped rod 42 under the support of the rotating pipe 28. One end of the T-shaped rod 42 away from the rotating pipe 28 is a counterweight. The spring 43 can resist the piston 44 to keep it in the discharge pipe 40 under the resistance of the L-shaped plate 41 by its own elastic force.

[0043] In the actual application process of this embodiment, after the staff injects incineration fly ash into the cleaning space, it is necessary to use fixing components to connect the pipeline for conveying clean water to the L-pipe 36 and the drain pipe 50. At the same time, it is necessary to connect the pipeline for discharging the water after cleaning to the flange pipe 47 through a valve and close the valve channel. After that, when the rotating pipe 28 is intermittently rotated by the rubber wheel 29 and the arc-shaped rubber block 26, the rotating pipe 28 will drive the drain pipe 40 and the L-plate 41 to rotate together by using the rotating power, so that the drain pipe 40 drives the piston 44 to rotate together. At the same time, the L-plate 41 will drive the T-rod 42 and the spring 43 to rotate together by using the rotating power, so that the piston 44 moves away from the central axis of the rotating pipe 28 by using the centrifugal force generated by the rotation. Furthermore, the piston 44 drives the rubber ring 46 to move outward along the drain pipe 40. At the same time, the piston 44 will use the centrifugal force to squeeze the spring 43 to contract during the movement, and at the same time push the T-rod 42 to penetrate the L-plate 41 and move away from the rotating pipe 28, so that the piston 44 moves out of the drain pipe 40 and opens the pipeline channel of the drain pipe 40. Subsequently, the clean water in the rotating pipe 28 will enter the drain pipe 40 by using the centrifugal force under the action of the rotating power, and pass through the drain pipe 40 after the piston 44 moves out of the drain pipe 40 and is discharged into the incineration fly ash in the cleaning space, and contact and mix with the incineration fly ash, so as to inject water in batches and intermittently and slowly, avoid the fly ash from agglomerating or generating adverse effects due to violent heat release when encountering the water injected in a rough way because of the alkaline substances contained, such as CaO, improve safety, and thus use the water discharged from the drain pipe 40. As time and the amount of water increase, the incineration fly ash is cleaned in the cleaning space in cooperation with the rotation of the baffle 30 and the disturbance plate 35. The excess water in the rotating pipe 28 will pass through the rotating pipe 28 and penetrate into the outer ring pipe 49 through the connecting pipe 38 under the sealing action of the rubber ring 46, and flow along the outer ring pipe 49 and be discharged into the drain pipe 50, and pass through the drain pipe 50 and be discharged from the connecting pipeline for recycling.

[0044] When the cleaning time arrives, the staff can control the valve connected to the flange pipe 47 to open, so that the water in the cleaning space can carry the soluble chlorides washed down and pass through the filter screen 48 into the flange pipe 47, and pass through the flange pipe 47 and be discharged from the connecting pipeline. At the same time, the filter screen 48 will intercept the incineration fly ash after cleaning to prevent the incineration fly ash from entering the flange pipe 47 and being discharged. Subsequently, the staff can replace the pipeline for conveying clean water with the pipeline for conveying steam and connect it to the L-pipe 36 and the drain pipe 50 according to the actual situation, so that the steam can be distributed to each rotating pipe 28 through the L-pipe 36, the inner ring pipe 37 and the connecting pipe 38, so that the steam enters the rotating pipe 28 and is discharged into the outer ring pipe 49 in cooperation with the connecting pipe 38, and finally passes through the drain pipe 50 and is discharged from the connecting pipeline, so that the rotating pipe 28 can use the steam entering its inner side to heat and dry the incineration fly ash in the cleaning space, and the staff can measure the dryness of the incineration fly ash by using the humidity sensor through the filling cylinder 19, and can control the solenoid valve 25 to open when the dryness reaches the appropriate range; After the cleaning water is drained or when it is necessary to dry and incinerate the fly ash and the dryness reaches an appropriate range, the staff can control the solenoid valve 25 to open, so that the incinerated fly ash in the cleaning space can move into the solenoid valve 25 under the action of the inclination angles of the inclined ring support 23 and the inclined cylinder 22, and the incinerated fly ash after cleaning can pass through the solenoid valve 25 and be discharged into the cylinder 1 for stirring and solidification. After the solenoid valve 25 is opened, the staff can inject the curing agent into the cylinder 1 through the cleaning space and the solenoid valve 25.

[0045] Working principle: Fly ash is injected into the disposal device through the injection cylinder 19. The opening and closing of the discharge port are controlled by the linkage of the electric rod 6 and the sector plate 3 to ensure that the fly ash is discharged only after solidification is completed. The fly ash first enters the cleaning space composed of the ring cylinder 21, the inclined cylinder 22, and the support ring 24. The motor 9 drives the transmission rod 10 to drive the stirring shovel part to rotate. The arc rubber block 26 of the stirring shovel part intermittently pushes the rubber wheel 29, so that the rotating pipe 28 drives the disturbing plate 30 and the disturbing plate 35 to rotate, disturbing the fly ash by water washing to remove soluble chlorides and avoiding interference of chloride ions in the subsequent solidification reaction. The centrifugal force controls the water injection (rotary discharge part) and the steam drying technology to prevent the fly ash from getting out of control due to heat release when encountering water, improving the safety.

[0046] The annotation part drives the discharge pipe 40 and the piston 44 to move outwards by centrifugal force, opening the pipeline by centrifugal force, and slowly injecting the clear water into the pre-washing space in batches to avoid violent heat release when the fly ash (containing alkaline substances such as CaO) encounters water. The cleaning water is discharged after being filtered by the filter screen 48, and the dried fly ash enters the cylinder 1 through the solenoid valve 25.

[0047] After the fly ash enters the cylinder 1, the transmission rod 10 drives the stirring rod 18 to revolve and rotate (driven by the meshing of the moving gear 17 and the fixed gear 15). The shovel plate 14 shovels up the fly ash at the bottom, and the stirring plate 13 stirs in multiple directions to eliminate the stirring dead zone. The curing agent (such as polyacrylate) is injected through the injection cylinder 19 and is fully mixed and chelated with the fly ash for solidification. The double-mode stirring of revolution plus rotation (the transmission rod 10 drives the stirring rod 18 to rotate plus the rotation of the moving gear 17 meshing) is combined with the design of the shovel plate 14 for shoveling materials, improving the stirring efficiency and the mixing uniformity of the curing agent, and significantly reducing the stirring dead zone.

[0048] After solidification is completed, the electric rod 6 drives the sector plate 3 to open the discharge port, and the solidified fly ash is discharged for resource utilization (such as building materials raw materials). The steam can be introduced into the pre-washing space through the annotation part to assist in drying, realizing energy recycling.

[0049] Through the innovation of the multi-level collaborative mechanical structure, the present invention solves the industrial problems such as low solidification efficiency of incinerated fly ash, chloride salt interference, and safety hazards, realizes the efficient harmless treatment and high-value resource utilization of fly ash, and has significant economic and environmental benefits.

[0050] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
