Description

Technical Field

[0001] The present invention relates to the technical field of garbage crushing and sorting, and specifically to a sorting and processing device for the slag of a garbage power generation incinerator. Background Art

[0002] The slag after garbage incineration refers to the solid residue formed after the non-combustible components in the garbage and some incompletely combusted organic matters are treated at high temperature during the garbage incineration process. These slags mainly come from the products after the incineration of domestic garbage, industrial garbage, etc.

[0003] However, there are three core problems in the traditional garbage incineration slag crushing process: metal deformation loss, adhesion blockage, and high energy consumption and low efficiency;

[0004] (1) Due to the mixed stress of metal and brittle materials in the single extrusion crushing mode, metals such as iron and copper are severely deformed and fragmented, reducing the subsequent sorting and recycling efficiency and increasing resource waste;

[0005] (2) The adhesive characteristics of the molten glass and plastic hot melt phases in the high-humidity slag lead to the continuous adhesion of viscous substances to the wall of the crushing chamber, causing frequent blockages and shutdowns, restricting the continuous production capacity; the repeated crushing requirements caused by the hardness difference of the mixed materials, combined with the lack of an energy recovery mechanism, push up the unit energy consumption to 1.220 kWh / ton, exacerbating the operating cost and carbon emission pressure, and severely weakening the economic and environmental benefits of resource treatment.

[0006] Therefore, a sorting and processing device for the slag of a garbage power generation incinerator is proposed to solve the above problems. Summary of the Invention

[0014] Preferably, a material distribution screen is fixedly connected to one end of the vibrating table away from the feeding hopper. A material distributor is arranged below the material distribution screen. One end of the material distributor away from the material distribution screen is fixedly communicated with the atomizing tipping chamber. A dust collection chamber is installed above the vibrating table and the material distribution screen. A dust collection device is installed in the dust collection chamber.

[0015] Preferably, the layered crushing mechanism includes an eccentric shaft. The two ends of the eccentric shaft are rotatably connected in the multi-functional crushing chamber. A transmission disc is installed on the multi-functional crushing chamber. The eccentric shaft is eccentrically rotatably connected to the transmission disc. A squeezing plate is fixedly connected to the eccentric shaft. One end of the squeezing plate away from the eccentric shaft is rotatably connected to a sliding rod. The outer surface of the sliding rod is slidably connected in the multi-functional crushing chamber. A return spring is sleeved on the outer surface of the sliding rod. One end of the return spring is fixedly connected to the sliding rod.

[0016] Preferably, the other end of the return spring is fixedly connected to the multi-functional crushing chamber. A pressing plate is arranged on the side of the squeezing plate away from the sliding rod. The pressing plate is fixedly connected to the inner wall of the multi-functional crushing chamber.

[0019] Compared with the prior art, the present invention provides a garbage power generation incinerator slag sorting and processing device, which has the following beneficial effects:

[0020] 1. The first driving motor is installed inside the sorting frame. It drives the transmission wheel to rotate through the motor drive shaft. During this rotation process, the transmission wheel can synchronously drive the cam to reciprocally press the inclined surface of the bevel block. When the convex surface of the cam collides with the bevel block, it will cause the energy absorption plate to vibrate and jitter in the horizontal direction. The functions of this vibration and jitter are as follows: on the one hand, it can make the garbage attached to the component energy absorption plate evenly distributed, and on the other hand, it can transfer the physical energy along the component 1 to the component multi-functional crushing chamber.

[0021] 2. In this solution, a material distribution sieve mesh device is configured at the front end feeding port of the multi-functional crushing chamber. This device can pre-separate small garbage, effectively avoiding the repeated crushing treatment of smaller garbage, and thus significantly reducing the crushing burden of the multi-functional crushing chamber device. At the same time, above the energy absorption plate and the material distribution sieve mesh device, a dust collection chamber device is particularly added. Its function is to collect the dust generated during the feeding and crushing of garbage; through the transmission and collection function of the dust collection chamber device, the escape of dust can be greatly reduced, thereby effectively reducing the environmental pollution caused by dust in the garbage crushing and sorting process and the potential harm to health.

[0022] 3. In this solution, an impact crushing layer and a roll pressing crushing layer are arranged in an upper and lower stacked manner. In this solution, the brittle slag blocks are quickly crushed through the impact and shearing actions of the high speed 301, avoiding the repeated extrusion deformation of metals. At the same time, the metal blocks are gently rolled at a low speed to retain the integrity of their physical forms, ensuring the recovery rate of subsequent magnetic separation / eddy current separation;

[0023] Compared with the traditional jaw crusher that crushes metals and slag blocks together, resulting in a reduction in the deformation rate of iron blocks and thus improving the metal purity after sorting, this solution innovatively adopts a double-layer crushing composite technology. This technology not only effectively reduces the over-crushing phenomenon of slag during the crushing process, but also significantly reduces the blockage problem of slag caused by crushing, thereby optimizing the overall crushing and sorting process.

[0036] 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.

[0037] Next, the present invention will be further described in detail according to the drawings and embodiments.

[0038] For the embodiments, please refer to Figures 1 to 7 as shown below:

[0039] To solve the problems mentioned in the technical solution, an embodiment of the present application provides a sorting and processing device for waste incineration slag of waste power generation, including a sorting frame 1, a feeding hopper 11 is installed on the sorting frame 1, a multi-functional crushing chamber 12 is installed in the middle of the side of the sorting frame 1 away from the feeding hopper 11, an atomizing and discharging chamber 13 is arranged below the multi-functional crushing chamber 12, a sorting chamber 14 is arranged on the side of the atomizing and discharging chamber 13 away from the multi-functional crushing chamber 12, and further includes a uniform feeding mechanism 2, a layered crushing mechanism 3 and a sorting mechanism 4;

[0040] The uniform feeding mechanism 2 is arranged on the sorting frame 1 and is used for uniformly feeding and sorting the waste;

[0041] The layered crushing mechanism 3 is arranged in the multi-functional crushing chamber 12 and is used for multi-stage crushing of the waste to prevent blockage;

[0042] The sorting mechanism 4 is arranged in the sorting chamber 14 and is used for sorting and collecting the crushed waste;

[0043] Specifically, as Figure 3 shown, a bracket 22 is fixedly connected to the sorting frame 1, a cam 23 is rotatably connected in the bracket 22, one end of the cam 23 is fixedly connected to a transmission wheel 21, an inclined block 24 is arranged above the cam 23, and a vibration table 25 is fixedly connected to the end of the inclined block 24 away from the cam 23;

[0044] Among them, the first driving motor is installed inside the sorting frame 1, and it drives the transmission wheel 21 to rotate through a motor drive shaft. During this rotation process, the transmission wheel 21 can synchronously drive the cam 23 to reciprocally squeeze the inclined surface of the inclined block 24. When the convex surface of the cam 23 collides with the inclined block 24, it will cause the energy absorption plate 27 to vibrate and jitter in the horizontal direction. The functions of this vibration and jitter are, on the one hand, to evenly distribute the waste attached to the component energy absorption plate 27, and on the other hand, to transfer the physical energy along the component 1 to the multi-functional crushing chamber 12.

[0045] Furthermore, vibration springs 26 are fixedly connected to the four peripheries of the bottom of the vibration table 25, and the ends of the vibration springs 26 away from the vibration table 25 are fixedly connected to the sorting frame 1. An energy absorption plate 27 is fixedly connected to the middle of the vibration table 25, and the vibration table 25 is arranged on the lower surface of the feeding hopper 11; a material distribution screen 28 is fixedly connected to the end of the vibration table 25 away from the feeding hopper 11, a material distributor 201 is arranged below the material distribution screen 28, and the end of the material distributor 201 away from the material distribution screen 28 is fixedly communicated with the atomizing and discharging chamber 13. A dust suction chamber 29 is installed above the vibration table 25 and the material distribution screen 28, and a dust suction device is installed in the dust suction chamber 29;

[0046] Among them, in this solution, a material distribution screen device No. 28 is configured at the front feeding port of the multi-functional crushing chamber 12. This device can pre-separate small garbage, effectively avoiding the repeated crushing treatment of smaller garbage, and thus significantly reducing the crushing burden of the multi-functional crushing chamber No. 12. At the same time, above the energy-absorbing plate No. 27 and the material distribution screen device No. 28, a dust collection chamber device No. 29 is specially added, and its function is to collect the dust generated during the feeding and crushing of garbage; through the transmission and collection function of the dust collection chamber device No. 29, the escape of dust can be greatly reduced, thereby effectively reducing the environmental pollution caused by dust in the garbage crushing and sorting process and the potential harm to health.

[0047] Specifically, as Figure 3 , Figure 5 and Figure 6 shown, both ends of the eccentric shaft 31 are rotatably connected in the multi-functional crushing chamber 12. A transmission disk is installed on the multi-functional crushing chamber 12. The eccentric shaft 31 is eccentrically rotatably connected to the transmission disk. A squeezing plate 32 is fixedly connected to the eccentric shaft 31. One end of the squeezing plate 32 away from the eccentric shaft 31 is rotatably connected to a sliding rod 33. The outer surface of the sliding rod 33 is slidably connected in the multi-functional crushing chamber 12. A return spring 34 is sleeved on the outer surface of the sliding rod 33. One end of the return spring 34 is fixedly connected to the sliding rod 33;

[0048] In this solution, the eccentric shaft 31 is eccentrically rotatably connected to the transmission disk. When the transmission disk rotates, due to the eccentric effect, the eccentric shaft 31 will start to have a small-range squeezing and shaking to the left. At this time, the squeezing plate 32 will gradually approach and squeeze the pressing plate 35, so that the garbage fragments are crushed under the mutual extrusion of the squeezing plate 32 and the pressing plate 35.

[0049] Furthermore, the other end of the return spring 34 is fixedly connected to the multi-functional crushing chamber 12. A pressing plate 35 is arranged on the side of the squeezing plate 32 away from the sliding rod 33. The pressing plate 35 is fixedly connected to the inner wall of the multi-functional crushing chamber 12. Uniformly fixed connection squeezing guide plates 36 are arranged on the side of the squeezing plate 32 and the pressing plate 35 close to each other. A rotating shaft 37 is rotatably connected in the middle of the multi-functional crushing chamber 12. Uniformly fixed connection connecting rings 38 are arranged on the rotating shaft 37. Swing arms 39 are circumferentially rotatably connected to the connecting rings 38. Symmetrically rotatably connected crushing hammers 301 are arranged at one end of the connecting rings 38 away from the connecting rings 38. The outer surfaces of the crushing hammers 301 slide on both sides of the squeezing guide plates 36;

[0050] Among them, the connecting ring 38 is linearly and fixedly connected to the rotating shaft 37. Both ends of the rotating shaft 37 are driven by belts to the driving disks. One side of the breaker 301 slides on both sides of the extrusion feeding plate 36. Through the setting of the extrusion feeding plate 36, not only can the garbage blocks be effectively broken, but also through the preliminary breaking of the breaker 301 and the extrusion feeding plate 36, the single extrusion breaking mode adopted by the traditional crusher can be reduced, resulting in excessive deformation or even fragmentation of metals such as iron and copper, reducing the subsequent magnetic separation / eddy current separation efficiency. Moreover, after breaking the water, it is beneficial for the squeezing plate 32 and the pressing plate 35 to perform secondary breaking on the garbage, reducing the blockage during garbage breaking.

[0051] Furthermore, as Figure 5 shown, a shock-absorbing plate 302 is arranged above the rotating shaft 37. The shock-absorbing plate 302 is slidably connected to the inner wall of the multi-functional crushing chamber 12. The upper surface of the shock-absorbing plate 302 is uniformly and fixedly connected with sliding shafts 303. The outer surfaces of the sliding shafts 303 are slidably connected to the multi-functional crushing chamber 12. A buffer spring 304 is sleeved on the outer surface of the sliding shaft 303 near the outside of the multi-functional crushing chamber 12. A nut 305 is threadedly connected above the sliding shaft 303 near the buffer spring 304;

[0052] Among them, the upper layer of the multi-functional crushing chamber 12 is the impact layer, and the lower layer is the roll pressing layer. The impact layer and the roll pressing layer are independently sealed. Combined with the negative pressure dust removal system, the dust concentration < 5mg / m 3 ; The roll pressing layer operates at a low speed to reduce dust emission. The top of the impact layer is integrated with a water mist spray with a particle size < 50μm to inhibit the diffusion of PM2.5.

[0053] Among them, grooves are uniformly formed at the bottom of the shock-absorbing plate 302, and the bottom of the shock-absorbing plate 302 is made of a flexible and elastic colloidal material, which can reduce the vibration of the inner wall of the multi-functional crushing chamber 12 during slag crushing. At the same time, by adjusting the threaded connection between the nut 305 and the sliding shaft 303, the sliding distance of the shock-absorbing plate 302 in the multi-functional crushing chamber 12 can be controlled, so that the noise generated by the splashing during slag crushing can be more effectively reduced by controlling the height of the shock-absorbing plate 302.

[0054] In this solution, by setting the high-speed hammer heads of the impact crushing layer and the low-speed roller wheels of the roll pressing crushing layer stacked up and down. In this solution, through the high-speed rotation of 301 at 1500 - 2000 rpm, brittle slag blocks such as glass, ceramics, and stones are quickly crushed through impact and shearing actions, avoiding the repeated extrusion deformation of metals. At the same time, the low-speed squeezing plate 32 applies a pressure of 5 - 20 MPa to gently roll the metal blocks, maintaining the integrity of their physical form with a deformation rate < 5%, ensuring that the recovery rates of copper and aluminum in the subsequent magnetic separation / eddy current separation are increased by 20% - 30%. Compared with the traditional jaw crusher where metals and slag blocks are mixed and crushed, the deformation rate of iron blocks reaches 30% - 50%, resulting in a decrease in the purity of the separated metals.

[0055] The sorting mechanism 4 includes a powder sieve barrel 41. A water spraying valve is evenly installed in the atomizing pouring chamber 13. The powder sieve barrel 41 is obliquely and rotatably connected in the sorting chamber 14. Filter holes are evenly formed on the outer surface of the powder sieve barrel 41. An arc-shaped guide plate 42 is fixedly connected to the inner surface of the powder sieve barrel 41. A water collecting chamber 43 is formed at the bottom of the sorting chamber 14. A material receiving plate 44 is arranged above the water collecting chamber 43. Both sides of the material receiving plate 44 are fixedly connected in the sorting chamber 14;

[0056] The specific implementation process of the above embodiment is as follows:

[0057] The sorting of municipal solid waste incineration bottom ash is a process of separating recyclable resources such as metals, glass, and aggregates and non-recyclable residues from the bottom ash generated after incineration through physical methods. Its core goal is to achieve resource utilization and reduce landfill volume. The following are the detailed sorting steps and specific embodiment descriptions:

[0058] I. Pretreatment stage

[0059] 1. Cooling and preliminary crushing:

[0060] The temperature of the bottom ash after incineration is as high as 300 - 500 °C, and it needs to be quickly cooled to below 80 °C through a water-cooled screw conveyor or an air-cooling system to avoid high-temperature damage to the equipment.

[0061] Preliminary crushing:

[0062] Use the crusher or impact crusher in this solution to crush the large bottom ash pieces to a particle size <50 mm for subsequent sorting.

[0063] The specific operation is as follows:

[0064] First, the slag after cooling is transported to the energy-absorbing plate 27 through the feeding hopper 11 for transmission. At this time, by starting the driving motor in the sorting rack 1 to rotate, the driving wheel 21 is driven to rotate by the motor drive shaft. During this rotation process, the driving wheel 21 can synchronously drive the cam 23 to reciprocally press the inclined surface of the angled block 24. When the convex surface of the cam 23 collides with the angled block 24, it will cause the energy-absorbing plate 27 to vibrate and jitter in the horizontal direction. The functions of this vibration and jitter are, on the one hand, to evenly distribute the garbage attached to the energy-absorbing plate 27 of the component, and on the other hand, to transfer the physical energy along the component 1 to the multi-functional crushing chamber 12. At this time, since the feeding port at the front end of the multi-functional crushing chamber 12 is equipped with a material separation sieve mesh device No. 28, this device can pre-separate the fine garbage, effectively avoiding the repeated crushing treatment of smaller garbage, and thus significantly reducing the crushing burden of the multi-functional crushing chamber No. 12 equipment. At the same time, above the energy-absorbing plate 27 and the material separation sieve mesh device No. 28, a dust collection chamber device No. 29 is specially added, and its function is to collect the dust generated during the feeding and crushing of the garbage; through the transmission and collection function of the dust collection chamber device No. 29, the escape of dust can be greatly reduced, thereby effectively reducing the environmental pollution caused by dust in the garbage crushing and sorting process and the potential harm that may be caused to health;

[0065] At this time, the slag that has been preliminarily pushed will fall into the multi-functional crushing chamber 12. Since the upper layer of the multi-functional crushing chamber 12 in this solution is the impact layer and the lower layer is the roll pressing layer, the impact layer and the roll pressing layer are independently sealed, and the dust concentration in combination with the negative pressure dust removal system is <5mg / m 3 ; The roll pressing layer operates at a low speed to reduce dust emission. When the material evenly falls on the upper impact layer of the multi-functional crushing chamber 12, through the preliminary crushing of the slag by the crushing hammer 301, the larger slag is broken into uniform small slag. And the crushed slag is roll pressed by the lower roll pressing layer. This can not only prevent the metal from deforming due to repeated extrusion, but also use the slow-speed extrusion plate 32 with a pressure of 5 - 20 MPa to gently roll the metal block, retaining the integrity of its physical form with a deformation rate <5%, ensuring that the recovery rates of copper and aluminum in the subsequent magnetic separation / eddy current separation are increased by 20% - 30%. Compared with the traditional jaw crusher where the metal and slag blocks are mixed and crushed, the deformation rate of the iron block reaches 30% - 50%, resulting in a decrease in the purity of the separated metal.

[0066] Iron removal and screening;

[0067] Magnetic separation for iron removal: Immediately after crushing, use the powder sieve bucket 41 to separate ferromagnetic metals such as iron wires and iron nails, and the recovery rate can reach over 90%.

[0068] In this solution, the powder sieve barrel 41 is rotatably installed at a certain angle in the sorting chamber 14. When the powder sieve barrel 41 is driven to rotate by a motor, since the powder sieve barrel 41 can generate a certain magnetism through an electric control effect, at this time, when the powder sieve barrel 41 rotates, the slag with small molecules can be filtered onto the material receiving plate 44, and the metal is gradually pushed into the collection tank under the adsorption effect of the powder sieve barrel 41.

[0069] The slag is classified by particle size through a single-layer or multi-layer vibrating screen, such as >10mm, 5-10mm, <5mm, to provide materials with uniform particle size for subsequent sorting.

[0070] Dust control: A bag filter + wet spray system is equipped throughout the process to ensure that the dust emission concentration < 10mg / m 3 .
