Description

Technical Field

[0001] The present invention relates to the technical field of resource utilization and disposal of waste incineration fly ash, and in particular to a device for resource utilization and disposal of 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 equipment still has problems that need to be solved urgently.

[0003] For example, existing technologies usually use the method of directly stirring the 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. Summary of the Invention

[0004] The present invention provides a device for resource utilization and disposal of fly ash from the incineration of domestic waste.

[0084] Specifically, a support frame 2 is fixed to the bottom of the cylinder 1, a connecting plate 4 is fixed to one end of the fan-shaped plate 3, a rotary switch is fixed to the outside of the cylinder 1, and a rotating rod 5 is rotatably connected to the end of the fan-shaped plate 3, and an electric rod 6 is rotatably connected to the outside of the cylinder 1.

The cylinder 1 can provide a stable support for the end cover 7, the support frame 2 can support the cylinder 1, and a discharge port is opened at the position corresponding to the cylinder 1 and the fan-shaped plate 3. The fan-shaped plate 3 is as shown in FIG. Figure 2The state shown can seal the discharge port. The electric rod 6 can provide support for the fan plate 3 through the connecting plate 4 under the support of the cylinder 1, and the rotating rod 5 can also provide support for the fan plate 3 through the connecting plate 4. The end cover 7 can provide support for the transmission 8, and the transmission 8 can support the motor 9, and the motor 9 can use the driving end to drive the transmission 8 to operate. The transmission 8 can adjust the output rotation speed and can drive the transmission rod 10 to rotate together. The transmission rod 10 can provide support for the bracket 11 and can provide rotation support for the stirring rod 12. The end cover 7 can provide stable support for the filling cylinder 19. The filling cylinder 19 can provide a filling channel for domestic waste incineration fly ash. The cylinder 1 is symmetrically and rotatably connected with a cover 20, and the cover 20 cooperates with the filling cylinder 19.

[0085] In the actual application process of this embodiment: the staff needs to place the cylinder 1 at the work site with the support of the support frame 2, and rotate the cover 20 to open the opening of the filling cylinder 19 under the support of the end cover 7, so as to facilitate the filling of the incineration fly ash. When the incineration fly ash falls into the cylinder 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 18 to rotate together, so that the stirring plate 13 can use the rotational power to stir the incineration fly ash. At the same time, it is necessary to add a curing agent, including but not limited to a polyacrylate solution, into the cylinder 1 through the filling cylinder 19 to make the incineration fly ash The fly ash is stirred and mixed with the curing agent, so that the fly ash reacts to achieve solidification. After the solidification of the fly ash is completed, the staff needs to control the extension of the electric rod 6 so that the electric rod 6 uses the telescopic end to push the fan-shaped 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 1, and the telescopic end of the electric rod 6 will rotate at the same time under the support of the connecting plate 4, so that the connecting plate 4 can rotate counterclockwise under the support of the rotating rod 5, and the connecting plate 4 drives the fan-shaped plate 3 to move out from the bottom of the cylinder 1, and then open the discharge port, so that the fly ash after solidification in the cylinder 1 can be discharged and collected for resource utilization.

[0086] As a preferred embodiment of the present invention, the pushing member includes:

[0087] The bracket 11 is fixed to the outside of the transmission rod 10 and is located inside the cylinder 1;

[0088] The rotating rod 16 is symmetrically arranged through the bracket 11 and is fixedly connected to the stirring rod 18;

[0089] There are two arc rubber blocks 26 symmetrically fixed on the bracket 11 .

[0090] Specifically, a support cylinder 51 is fixed to the bottom end of the transmission 8, and the support cylinder 51 is located on the inner side of the end cover 7. A fixed gear 15 is fixed to the outer side of the support cylinder 51, and a movable gear 17 is fixed to the outer side of the rotating rod 16, and the movable gear 17 is engaged with the fixed gear 15.

The transmission rod 10 can provide support for the bracket 11, and the arc rubber block 26 can use friction to push the rubber wheel 29 in contact with it to rotate under the support of the bracket 11.

[0091] The stirring shovel parts include:

[0092] There are two stirring rods 12, which are symmetrically arranged through the bracket 11 and staggered with the rotating rod 16;

[0093] A stirring plate 13 is fixed to the bottom end of one of the stirring rods 12;

[0095] Specifically, the bracket 11 can provide stable support for the stirring rod 12, and the stirring rod 12 can provide stable support for the stirring plate 13 and the shovel plate 14. The stirring plate 13 can rotate with the bracket 11 under the drive of the stirring rod 12, and participate in the work of stirring fly ash during the rotation process. At the same time, the shovel plate 14 will rotate with the bracket 11 under the support of another stirring rod 12, and use the inclination angle and rotational power to shovel up the fly ash on the bottom wall of the cylinder 1 during the rotation process.

[0096] In actual application of this embodiment, when the motor 9 is started 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.

Thereby, the stirring rod 18 can rotate while revolving around the transmission rod 10 as the center, thereby improving the stirring efficiency and effect. At the same time, the bracket 11 will drive the shovel 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 shovel plate 14 will rotate clockwise together with the stirring rod 12 driven by the bracket 11, so that the shovel plate 14 can use its own inclination angle to shovel up the incineration fly ash near the bottom wall of the cylinder 1 during the rotation process.

The connecting pipe 38 can provide support for the inner ring tube 37 and the outer ring tube 49 under the support of the coil 28. The outer ring tube 49 can provide support for the drain pipe 40, and the outer ring tube 49, the inner ring tube 37, the coil 28, the connecting pipe 38, the L tube 36 and the drain pipe 50 can provide a circulation channel for water or steam.

[0131] The rotating parts include:

[0132] There are multiple rows of pipes 40, which are symmetrically arranged throughout the coil 28;

[0133] A piston 44 is movably disposed in the discharge pipe 40;

[0134] An annular groove 45 is provided on the outer side of the piston 44;

[0135] The rubber ring 46 is arranged inside the annular groove 45 and fits against the inner wall of the drain pipe 40;

[0136] Auxiliary parts are arranged on the outside of the coil 28.

[0137] Specifically, the drain pipe 40 can provide a discharge channel for the water in the coil 28, and can provide a moving space and guide for the piston 44 under the support of the coil 28. The piston 44 can provide an opening space for the annular groove 45. The annular 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 fit with the drain pipe 40 to play a sealing role.

[0138] Auxiliary parts include:

[0139] There are multiple L-plates 41 , which are symmetrically fixed to the outside of the coil 28 and extend to the end of the row tube 40 away from the coil 28 ;

[0140] A T-rod 42 is movably provided through the L-plate 41 and has one end fixedly connected to the piston 44;

[0141] The spring 43 is sleeved on the outside of the T-rod 42 and is located between the L-plate 41 and the piston 44 .

[0142] Specifically, a drain pipe 50 is connected to one side of the outer ring tube 49. The L-plate 41 can provide a through channel and guide for the T-rod 42 under the support of the spiral tube 28. The end of the T-rod 42 away from the spiral tube 28 is a counterweight. The spring 43 can use its own elastic force to resist the piston 44 and keep it in the drain pipe 40 under the resistance of the L-plate 41.

[0143] In actual application of this embodiment, after the staff injects the incineration fly ash into the cleaning space, it is necessary to use a fixing component to connect the pipeline for conveying clean water to the L-tube 36 and the drain pipe 50. At the same time, it is necessary to connect the pipeline for discharging the cleaned water to the flange pipe 47 through a valve, and close the valve channel. Thereafter, when the coil 28 is driven by the rubber wheel 29 and the arc rubber block 26 to rotate intermittently, the coil 28 will use the rotational force to drive the drain pipe 40 and the L-plate 41 to rotate together, so that the drain pipe 40 drives the piston 44 to rotate together. At the same time, the L-plate 41 will use the rotational force to drive the T-rod 42 and the spring 43 to rotate together, so that the piston 44 uses the centrifugal force generated by the rotation to move in the direction away from the central axis of the coil 28, and then 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 pass through the L-plate 41 to move in the direction away from the coil 28. Then the piston 44 is moved out of the drain pipe 40, opening the pipe passage of the drain pipe 40. Subsequently, the clean water in the coil 28 will enter the drain pipe 40 under the action of the rotating power by centrifugal force, and pass through the drain pipe 40 after the piston 44 is moved 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, thereby intermittently and slowly injecting water in batches to prevent the fly ash from containing alkaline substances, such as CaO, from agglomerating or violently releasing heat when encountering the extensively injected water, thereby improving safety. The water discharged from the drain pipe 40 is used to clean the incineration fly ash in the cleaning space in conjunction with the rotation of the disruptor plate 30 and the disruptor plate 35 as time goes by and the amount of water increases, and the excess water in the coil 28 will pass through the coil 28 and, under the sealing action of the rubber ring 46, penetrate the connecting pipe 38 into the outer ring pipe 49, and flow along the outer ring pipe 49 to be discharged into the drain pipe 50, and pass through the drain pipe 50 to be discharged from the connecting pipe for recycling.

[0144] When the cleaning time is reached, 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 cleaned soluble chloride salt through the filter 48 into the flange pipe 47 and pass through the flange pipe 47 to be discharged from the connecting pipe. At the same time, the filter 48 will intercept the cleaned incineration fly ash to prevent the incineration fly ash from entering the flange pipe 47 and being discharged. Then, the staff can replace the steam delivery pipeline with the clean water delivery pipeline and connect it to the L pipe 36 and the drain pipe 50 according to actual needs, so that the steam can be distributed to each coil 28 through the L pipe 36, the inner ring pipe 37 and the connecting pipe 38, so that the steam enters the coil 28 and is discharged into the outer ring pipe 49 in conjunction with the connecting pipe 38, and finally passes through the drain pipe 50 to be discharged from the connecting pipe, so that the coil 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 use the humidity sensor to measure the dryness of the incineration fly ash through the filling cylinder 19. When the dryness reaches a suitable range, the solenoid valve 25 can be controlled to open;

[0145] After the cleaning water is discharged or when the incineration fly ash needs to be dried and the dryness reaches an appropriate range, the staff can control the solenoid valve 25 to open, so that the incineration fly ash in the cleaning space can move into the solenoid valve 25 under the action of the inclination angle of the inclined ring support 23 and the inclined cylinder 22, so that the cleaned incineration fly ash can be discharged through the solenoid valve 25 into the cylinder 1 for stirring and solidification. After the solenoid valve 25 is opened, the staff can add the curing agent into the cylinder 1 through the cleaning space and the solenoid valve 25.

[0146] Working principle: fly ash is injected into the disposal device through the filling cylinder 19, and the opening and closing of the discharge port is controlled by the linkage between the electric rod 6 and the sector plate 3 to ensure that the fly ash is discharged only after solidification is completed;

[0147] Fly ash first enters the cleaning chamber formed by annular cylinder 21, inclined cylinder 22, and support ring 24. Motor 9 drives transmission rod 10, which rotates the stirring shovel. The arc rubber block 26 of the stirring shovel intermittently pushes rubber wheel 29, causing spiral tube 28 to rotate disruptor plate 30 and disruptor plate 35. This washes and disturbs the fly ash, removing soluble chloride salts and preventing chloride ion interference in the subsequent solidification reaction. Centrifugal force-controlled water injection (rotating element) and steam drying technology prevent uncontrolled heat release when the fly ash contacts water, improving safety.

[0148] The annotation part drives the discharge pipe 40 and the piston 44 outward by centrifugal force, and uses the centrifugal force to open the pipeline, so that clean water is slowly injected into the pre-wash space in batches to prevent the fly ash (containing alkaline substances such as CaO) from releasing heat violently when it comes into contact with water. The cleaning water is filtered through the filter 48 and then discharged. After the fly ash is dried, it enters the cylinder 1 through the solenoid valve 25.

[0149] After the fly ash enters the cylinder 1, the transmission rod 10 drives the stirring rod 18 to revolve and rotate (the moving gear 17 and the fixed gear 15 are engaged and driven), the shovel plate 14 scoops 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 filling cylinder 19, fully mixed with the fly ash and chelated and solidified. The dual-mode stirring of revolution and rotation is adopted (the transmission rod 10 drives the stirring rod 18 to rotate and the moving gear 17 is engaged and rotated). Combined with the shoveling design of the shovel plate 14, the stirring efficiency is improved, the mixing uniformity of the curing agent is improved, and the stirring dead zone is significantly reduced.

[0150] After solidification is completed, the electric rod 6 drives the fan-shaped plate 3 to open the discharge port, and the solidified fly ash is discharged for resource utilization (such as building materials). Steam can be introduced into the pre-washing space through the injection part to assist drying, realizing energy circulation.

[0151] Through the innovation of multi-stage coordinated mechanical structure, the present invention solves industry problems such as low solidification efficiency of incineration fly ash, chloride and salt interference, and safety hazards, and realizes efficient and harmless disposal of fly ash and high-value resource utilization, with significant economic and environmental benefits.

[0152] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
