Description

Technical Field

[0001] The invention belongs to the technical field of garbage disposal, and in particular relates to a device for sorting and processing stale garbage and decoration garbage. Background Art

[0002] Aged waste, also known as mineral waste, refers to municipal solid waste that has been stored in landfills or other dumps for many years. Aged waste is waste that has been unearthed and is now being processed. This waste is typically older and was previously landfilled due to outdated processing technology. It now needs to be processed, hence the term "aged waste."

[0003] Re-excavating and reducing stale waste can reduce land resource waste, allow for the reuse of landfill sites, and achieve harmless waste treatment, eliminating landfill pollution to the surrounding environment and groundwater, improving the ecological environment, and achieving significant environmental and social benefits. Furthermore, the treatment of stale waste can also yield recyclable resources, achieving resource recycling.

[0004] The working process of the stale garbage processing device is generally to transport it to the chain feeder through a loader, and then transport it to the manual sorting area through a lifting conveyor belt. Larger interference objects such as larger bricks, tiles, stones, chemical fiber fabrics, etc. are manually picked out. The garbage after manual sorting is then screened. The slag under the screen can be used as humus soil for greening nutrient soil or landfill after magnetic separation. The screened material enters the wind sorting system to select light materials and heavy materials. The heavy materials are separated from the metal by a magnetic separator and used as building aggregates, while the light films and combustibles are packaged by a hydraulic baler and sent to an incineration power plant.

[0005] However, it is inevitable that there is a lot of renovation waste mixed in the stale garbage. When the stale garbage is screened, the debris attached to the renovation garbage has a certain humidity, which will lead to poor separation of the debris in the stale garbage and the renovation garbage. That is, after screening, the renovation garbage will still be attached with a lot of moist debris, which is not conducive to the subsequent utilization of the renovation garbage and may even affect the strength of the building aggregate during reuse. Moreover, when the renovation garbage is manually sorted, only large pieces of renovation garbage are sorted, and the processing device does not crush the renovation garbage. Large pieces of renovation garbage will cause trouble for the subsequent magnetic separation and will also burden the subsequent transportation of the renovation garbage, which is not conducive to the subsequent reuse of the renovation garbage. Summary of the Invention

[0006] In order to solve the technical problems that after the above-mentioned stale garbage is screened, a lot of moist debris will still adhere to the decoration garbage, and the decoration garbage is large in volume and is not conducive to subsequent transportation and utilization, the present invention provides a stale garbage and decoration garbage classification and processing device.

DETAILED DESCRIPTION

[0038] The terms "first", "second", etc. in the description of this application and the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order.

[0039] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] The embodiment of the present invention provides a device for sorting and processing stale garbage and decoration garbage, such as Figure 1-12 As shown, the device for sorting and processing stale garbage and renovation garbage includes: a chain plate feeder 1, a screening mechanism 2, an air separation device 3, a first magnetic separator 41, a second magnetic separator 42, a crushing device 5 and a hydraulic baler 6;

[0041] Among them, the chain plate feeder 1 is used to evenly transport the mixed garbage dropped by the loader, and then transport it to the manual sorting area through the conveyor belt to sort out large pieces of bricks, tiles, stones and chemical fiber fabrics and other large interference objects in the mixed garbage. Then the mixed garbage is transported to the screening mechanism, and the screened material is mainly slag, and the screened material is sorted by the first magnetic separator 41. The sorted metal substances are recycled and reused. The slag after magnetic separation can be used as humus soil for greening nutrient soil or landfill. The screened material is transported to the air separation equipment 3 by the conveyor for air separation. The light materials selected by the air are mainly light films and combustibles, which are then transported to the hydraulic baler 6 for packaging as fuel for incineration power plants. The heavy materials are mainly decoration waste. After being transported to the crushing equipment 5 and crushed, the metal substances are sorted out by the second magnetic separator 42. The magnetically selected materials can be used as building aggregates.

[0042] It's important to note that because stale garbage is often mixed with renovation waste, and the soil attached to the renovation waste is damp, the separation of the soil from the stale garbage during screening is ineffective. Even after screening, a significant amount of damp soil still clings to the renovation waste. This situation hinders the subsequent utilization of the renovation waste and may even affect the strength of the building aggregate when it is reused.

[0043] Furthermore, current processing equipment relies primarily on manual labor to sort renovation waste, and only sorts large chunks. This means the waste isn't broken up in the processing equipment. Large chunks of waste can complicate subsequent magnetic separation and increase the burden of waste transportation, further impacting its subsequent reuse.

[0044] Therefore, the existing stale garbage and decoration garbage classification and processing equipment has problems such as poor separation effect, insufficient fragmentation of decoration garbage and difficulty in subsequent utilization during the processing process.

[0045] In this device, the chain feeder 1 disperses the stale garbage and evenly transports it to the manual sorting area. After large, interfering objects are sorted out, the garbage is transported to the screening mechanism 2, where the slag is screened out. The slag is then magnetically separated by the first magnetic separator 41 and used as humus for landscaping or landfill, achieving resource reuse. The metal materials removed by the magnetic separation can be recycled. The overscreen material is then air-sorted by the air separation device 3, where it is air-sorted to remove light film and combustible materials. These materials are then packaged by the hydraulic baler 6 and used as fuel for an incineration power plant, achieving energy reuse. The heavy materials separated by the air separation device 3, primarily renovation waste, are transported to the crushing device 5 for crushing, reducing the volume of the waste and facilitating subsequent transportation and recycling. The crushed waste is then sorted by the second magnetic separator 42, where the metal materials are separated for recycling. The magnetically separated materials can be used as building aggregate, achieving resource utilization of the renovation waste.

[0046] In general, this device achieves refined sorting and treatment of stale and renovation waste. This treatment method not only improves the efficiency and quality of waste treatment, but also achieves resource reuse and energy recovery, with significant environmental and economic benefits.

[0047] In a further preferred embodiment of the present invention, the screening mechanism 2 includes: a first base frame 21 supported on the ground; a drum screen 22 arranged on the first base frame 21, a spiral conveying auger fixedly installed on the inner wall of the drum screen 22, both ends of the drum screen 22 are set to be openings, and a first feed port 23 and a first discharge port 24 are respectively provided, and the bottom of the first feed port 23 and the first discharge port 24 are fixedly installed with a plurality of support members fixed to the first base frame 21; four support assemblies for supporting the drum screen 22, and the four support assemblies are all arranged on the first base frame 21; a drive assembly for driving the drum screen 22 to rotate, and the drive assembly is assembled on the first base frame 21.

[0048] In this embodiment, the screening mechanism 2 is described and designed in detail. The purpose of this embodiment is to improve the screening efficiency and effect, so as to better achieve the effective separation of the slag and the renovation waste in the stale garbage.

[0049] First, the screening mechanism 2 comprises a first underframe 21 supported on the ground. This underframe not only provides a solid foundation for the entire device, but also helps maintain the stability of the screening process.

[0050] Next, mounted on the first chassis 21 is a trommel 22, a commonly used screening component that screens material through the rotation of a drum. In the present invention, a spiral conveyor auger is fixedly mounted on the inner wall of the trommel 22. This design ensures that material is evenly and continuously moved from the feed inlet to the discharge outlet during the screening process, resulting in uniform screening of the waste.

[0051] In order to stably support the drum screen 22, four support assemblies are also designed, which are all arranged on the first chassis 21. These support assemblies can not only ensure that the drum screen remains stable during operation, but also can withstand impact and vibration from the material.

[0052] Finally, a drive assembly for driving the drum screen 22 to rotate is assembled on the first chassis 21. This drive assembly provides the necessary rotational power for the drum screen, thereby enabling it to perform screening work continuously and efficiently.

[0053] In a further preferred embodiment of the present invention, the support assembly includes: a support seat 25 fixedly mounted on the first base frame 21, with a wheel axle fixedly mounted on the support seat 25; and a support roller 26 rotatably mounted on the wheel axle, the support roller 26 is in contact with the outer wall of the drum screen 22.

[0054] In this embodiment, the support base 25 is fixedly mounted on the first base frame 21, which provides a stable foundation for the entire support assembly. A wheel axle is fixedly mounted on the support base 25, and the function of the wheel axle is to provide an axis of rotation for the support roller 26. The support roller 26 is rotatably mounted on the wheel axle, which means that the support roller 26 can rotate freely around the wheel axle. More importantly, the outer wall of the support roller 26 contacts the outer wall of the drum screen 22. In this way, when the drum screen 22 rotates, it rolls on the support roller 26, and the support roller 26 plays a supporting and guiding role, ensuring that the drum screen 22 can rotate smoothly and steadily.

[0055] In a further preferred embodiment of the present invention, four limit rings 27 are fixedly installed on the outer wall of the drum screen 22. The four limit rings 27 are grouped in twos, and the limit rings 27 in a group of two are used to limit the area of ​​rolling connection between the outer wall of the drum screen 22 and the support roller 26.

[0056] In this embodiment, four retaining rings 27 are fixedly mounted on the outer wall of the drum screen 22. These retaining rings 27 are not randomly distributed, but are arranged in groups of two, for a total of two groups. This design primarily allows for more precise control of the rolling contact area between the drum screen 22 and the support rollers 26. When the drum screen 22 rolls on the support rollers 26, its outer wall comes into contact with the support rollers 26. The retaining rings 27 limit this contact to a specific area, ensuring the stability of the drum screen 22 during rolling.

[0057] In a further preferred embodiment of the present invention, the drive assembly includes: a plurality of pillars 28 fixedly mounted on the first base frame 21, a support plate 29 fixedly mounted between the plurality of pillars 28, and the support plate 29 is located directly above the drum screen 22; two fixed seats 30 fixedly mounted at the bottom of the support plate 29, and a mounting shaft is rotatably mounted on the two fixed seats 30, and a main gear 31 is fixedly sleeved on the mounting shaft; a ring gear 32 fixedly sleeved on the outer wall of the drum screen 22, and the ring gear 32 is meshed with the main gear 31; a reduction motor 33 fixedly mounted on the top of the support plate 29, and a first sprocket 34 is fixedly sleeved on the output shaft of the reduction motor 33 and the mounting shaft, and the two first sprockets 34 are connected by a chain.

[0058] In this embodiment, the drive assembly primarily powers the trommel 22, enabling its rotation. First, the drive assembly comprises multiple struts 28 fixedly mounted to the first chassis 21. These struts 28 not only provide stable support for the entire drive assembly but are also distributed on either side of the trommel 22, ensuring a stable relative position between the drive assembly and the trommel 22. A support plate 29 is fixedly mounted between the struts 28. This support plate 29 is located directly above the trommel 22, providing a foundation for subsequent component installation.

[0059] Next, the drive assembly includes two fixed bases 30 fixedly mounted on the bottom of the support plate 29. A mounting shaft is rotatably mounted on the two fixed bases 30, and a main gear 31 is fixedly sleeved on the mounting shaft. The main gear 31 is one of the key components that drives the drum screen 22 to rotate.

[0060] The drive assembly also includes a ring gear 32 fixedly mounted on the outer wall of the drum screen 22. This ring gear 32 meshes with the main gear 31. When the main gear 31 rotates, it drives the ring gear 32 and the drum screen 22 to rotate together. This gear transmission method has the advantages of simple structure and reliable transmission.

[0061] To drive the main gear 31, the drive assembly also includes a reduction motor 33 fixedly mounted on the top of the support plate 29. A first sprocket 34 is fixedly mounted on the output shaft of the reduction motor 33, while another first sprocket 34 is fixedly mounted on the mounting shaft. These two first sprockets 34 are connected by a chain. When the reduction motor 33 is activated, its power is transmitted through the chain to the mounting shaft and the main gear 31, thereby driving the drum screen 22.

[0062] This embodiment describes in detail the structure and working principle of the drive assembly, showing how to drive the drum screen 22 to rotate through the reduction motor 33, chain and gear transmission. This drive method is not only compact in structure and reliable in transmission, but also easy to maintain.

[0063] In a further preferred embodiment of the present invention, a material guide hopper 35 is fixedly mounted on the first chassis 21 , and the material guide hopper 35 is located directly below the sieve hole area of ​​the drum screen 22 .

[0064] In this embodiment, when the stale garbage is screened in the drum screen 22, the debris therein will fall through the sieve holes. Since the guide hopper 35 is located directly below the sieve hole area, the fallen debris will fall directly into the guide hopper 35. Then, through the guidance of the guide hopper 35, the material can be accurately transported to the next processing link.

[0065] In a further preferred embodiment of the present invention, the crushing equipment 5 includes: a second base frame 51 supported on the ground, a bottom box 52 is fixedly installed on the second base frame 51, a conveyor 54 for conveying crushed materials is installed in the bottom box 52, and one side of the bottom box 52 is set to be open and fixedly installed with a second discharge port 67; a crushing box 53 installed on the top of the bottom box 52, the crushing box 53 is connected to the bottom box 52, and a second feed port 66 is installed on one side of the crushing box 53; a double-layer crushing assembly is arranged in the crushing box 53, and the double-layer crushing assembly is used to crush the heavy material after air separation.

[0066] In this embodiment, the detailed structure and function of the crushing device 5 are further described. The crushing device 5 is primarily used to crush heavy materials after air separation. First, the crushing device 5 includes a second base frame 51 supported on the ground. This second base frame 51 provides stable support for the entire crushing device 5. A bottom box 52 is fixedly mounted on the second base frame 51. This bottom box 52 is used to accommodate and transport the crushed materials. A conveyor 54 is installed inside the bottom box 52. This conveyor 54 is responsible for transporting the crushed materials from one side of the bottom box 52 to the other side, and then discharging them through a second discharge port 67.

[0067] The crushing equipment 5 also includes a crushing box 53 mounted on top of the bottom box 52. This crushing box 53 is connected to the bottom box 52, allowing the crushed material to fall smoothly from the crushing box 53 into the bottom box 52. A second feed port 66 is installed on one side of the crushing box 53 for feeding the material to be crushed into the crushing box 53.

[0068] Finally, the core of the crushing equipment 5 is the dual-layer crushing assembly housed within the crushing box 53. This dual-layer crushing assembly utilizes advanced crushing technology to efficiently and thoroughly crush heavy materials after air separation. This crushing equipment 5 is not only compact and stable in operation, but also offers high crushing capacity and excellent crushing results.

[0069] In a further preferred embodiment of the present invention, the double-layer crushing assembly includes an upper layer crushing assembly and a lower layer crushing assembly, wherein the upper layer crushing assembly includes: a plurality of first rotating shafts 55 rotatably mounted on the inner walls of both sides of the crushing box 53, wherein the plurality of first rotating shafts 55 are arranged at equal intervals, and a plurality of first crushing blocks 56 are fixedly sleeved on the first rotating shafts 55, and the plurality of first crushing blocks 56 are arranged at equal intervals; a plurality of first gears 57 are respectively fixedly sleeved on one end of the plurality of first rotating shafts 55, and adjacent first gears 57 are meshed with each other;

[0071] In addition, a driving mechanism is fixedly installed on the second base frame 51 for driving the operation of the double-layer crushing assembly and the conveyor 54. The driving mechanism includes a main motor 61 fixedly installed on the second base frame 51. A pulley 64 is fixedly provided on the output shaft of the main motor 61 and one end of a roller shaft of the conveyor 54. A belt 65 is connected between the two pulleys 64.

Furthermore, a first gear 57 is fixedly mounted on one end of each first rotating shaft 55. Adjacent first gears 57 mesh with each other, forming a gear transmission system that enables all first rotating shafts 55 to rotate synchronously.

[0073] The structure and operating principle of the lower crushing assembly are similar to those of the upper crushing assembly, comprising several second rotating shafts 58 spaced evenly apart within the crushing chamber 53. Each second rotating shaft 58 is fixedly mounted with a plurality of second crushing segments 59. The spacing between these second crushing segments 59 is smaller than the spacing between the first crushing segments 56, allowing for further fine crushing of the initially crushed material. Similarly, a second gear 60 is fixedly mounted on one end of each second rotating shaft 58. Adjacent second gears 60 mesh with each other, forming a gear transmission system that enables all second rotating shafts 58 to rotate synchronously.

[0074] In order to drive the operation of the double-layer crushing assembly and the conveyor 54, this embodiment also provides a driving mechanism. The driving mechanism includes a main motor 61 fixedly mounted on the second chassis 51. A double sprocket 62 is fixedly provided on the output shaft of the main motor 61, and a pulley 64 is also fixedly provided on one end of a roller shaft of the conveyor 54. A belt 65 is connected between the two pulleys 64, so that the main motor 61 can drive the operation of the conveyor 54. In addition, a double sprocket 62 is also fixedly provided on the output shaft of the main motor 61, and a transmission sprocket 63 is fixedly provided on one end of any first rotating shaft 55 and any second rotating shaft 58. The two transmission sprockets 63 are connected to the double sprocket 62 by a chain, so that the main motor 61 can simultaneously drive the rotation of the corresponding first rotating shaft 55 and second rotating shaft 58 in the upper crushing assembly and the lower crushing assembly, and through the transmission of the meshing first gear 57 and the meshing second gear 60, the crushing blocks on the adjacent rotating shafts can rotate in opposite directions to crush the decoration waste;

[0075] In addition, the upper crushing component can process larger pieces of decoration waste into small pieces, while the lower crushing component can crush small pieces of decoration waste into fragments. It should be noted that the upper crushing component and the lower crushing component are both tilted, which can allow uncrushed decoration waste to move downstream, so that the crushing blocks on multiple groups of rotating shafts can crush the decoration waste. Compared with the traditional double-roller roller crusher, it is more efficient, and the synergistic effect of the upper and lower crushing components can achieve double crushing of the material and improve the crushing effect.

[0076] In a further preferred embodiment of the present invention, the crushing box 53 is also equipped with a blocking mechanism for blocking larger pieces of renovation waste. The blocking mechanism includes a central axis 70 fixedly mounted on the inner wall of the crushing box 53, a swivel 71 is rotatably sleeved on the central axis 70, a baffle 72 is fixedly mounted on the bottom of the swivel 71, and a fixed block 73 is fixedly mounted on the top inner wall of the crushing box 53, an arc-shaped slide rod 74 with the central axis 70 as the center is fixedly mounted on the fixed block 73, the baffle 72 is slidably sleeved on the arc-shaped slide rod 74, a spring 75 is slidably sleeved on the arc-shaped slide rod 74, and a limiting block is fixedly mounted on the end of the arc-shaped slide rod 74 away from the fixed block 73.

[0077] In this embodiment, the main purpose of the blocking mechanism is to block larger pieces of decoration waste and prevent them from falling into the lower crushing assembly without being crushed by the crushing blocks in the upper crushing assembly.

[0078] The central axis 70 in the blocking mechanism serves as a support and rotation center. A rotating ring 71 is mounted on the central axis 70, allowing it to rotate freely about the central axis 70. A baffle 72 is fixedly mounted at the bottom of the ring 71 to block larger pieces of renovation waste. To ensure that the baffle 72 can slide stably and return to its original position when blocking waste, a fixed block 73 is fixedly mounted on the top inner wall of the crushing box 53. A curved slide 74, centered on the central axis 70, is fixedly mounted on this fixed block 73. The baffle 72 slides onto this curved slide 74, allowing it to slide on it. A spring 75 is also mounted on this curved slide 74. This spring 75 provides the force to reset the baffle 72, ensuring that it automatically returns to its original position when no waste is blocking it. One end of the spring 75 is connected to the baffle 72 , and the other end is connected to the limit block on the arc-shaped slide rod 74 , so that the spring 75 can always maintain a certain tension to ensure the stable sliding of the baffle 72 .

[0079] The design of the baffle 72 rotation and the coordination of the arc-shaped slide bar 74 and the spring 75 can prevent large pieces of renovation waste from being rigidly blocked and getting stuck between the broken pieces. The design of the arc-shaped slide bar 74 and the spring 75 also enables the baffle 72 to achieve the functions of blocking and resetting.

[0080] In another embodiment of the present invention, the crushing equipment 5 is also equipped with a dust reduction mechanism for reducing dust at the second feed port 66 and the second discharge port 67, and the dust reduction mechanism includes: a fan 80 fixedly mounted on the second base frame 51, and an air inlet pipe 81 is fixedly mounted on the air inlet end of the fan 80; an installation box 82 is arranged on one side of the bottom box 52 and has an exhaust port on the top, and installation pipes 83 are fixedly mounted on both sides of the installation box 82, and the two installation pipes 83 extend into the crushing box 53, and the two installation pipes 83 are connected to the installation box 82; two suction hoods 84 are respectively fixedly mounted on one end of the two installation pipes 83, and the two suction hoods 84 are both located in the crushing box 53, and are respectively close to the second feed port 66 and the second discharge port 67; a filter 85 fixedly mounted in the installation box 82, and the filter 85 is used to filter dust in the extracted air.

[0081] In this embodiment, the dust suppression mechanism is used to reduce the dust generated by the crushing equipment 5 at the second feed port 66 and the second discharge port 67. The design of the dust suppression mechanism not only helps to keep the working environment clean, but also reduces the impact of dust on the health of workers.

[0082] The fan 80 in the dust reduction mechanism is used to extract the air in the crushing box 53 through the suction hood 84 at one end of the two mounting pipes 83, so that a negative pressure is formed in the crushing box 53, and the area with more dust is extracted in a targeted manner, while the external air enters the crushing box 53 through the second feed port 66 and the second discharge port 67, thereby reducing dust overflow. The extracted air and dust enter the mounting box 82 through the mounting pipe 83, and the dust in the extracted air is filtered by the filter 85 to ensure the quality of the air discharged to the outside of the mounting box 82, thereby improving the working environment and protecting the health of the staff.

[0083] In another embodiment of the present invention, an anti-blocking mechanism for cleaning the filter 85 is also installed in the installation box 82, and the anti-blocking mechanism includes: a mounting plate 86 arranged in the installation box 82 and located above the filter 85, and a plurality of fixing rods 87 fixedly connected to the inner wall of the installation box 82 are fixedly installed on the mounting plate 86; an auxiliary motor 88 fixedly installed on the mounting plate 86, and a connecting shaft 89 is fixedly installed on the output shaft of the auxiliary motor 88; and a brush strip 90 fixedly installed at the bottom end of the connecting shaft 89, and the brush on the brush strip 90 is in contact with the filter 85.

[0084] In this embodiment, the anti-blocking mechanism is intended to solve the problem of clogging that may occur during use of the filter 85. The design of the anti-blocking mechanism not only helps to keep the filter 85 clean, but also ensures that the dust suppression mechanism works continuously and effectively.

[0085] Specifically, by starting the auxiliary motor 88, the connecting shaft 89 is driven to rotate, which in turn drives the brush bar 90 to rotate. The bristles on the brush bar 90 come into contact with the filter 85. Therefore, the rotating brush bar 90 can clean the filter 85, thereby removing dust and other impurities attached to the filter 85 and maintaining the patency of the filter 85. At the same time, regular cleaning of the filter 85 can also extend its service life, reduce the frequency of filter replacement, and reduce maintenance costs.

[0086] In another embodiment of the present invention, an outer box body 91 connected to the installation box 82 is fixedly installed at the bottom of the installation box 82, and the outer box body 91 is fixedly connected to the second base frame 51. A collection box 92 for collecting dust is provided in the outer box body 91, and one side of the outer box body 91 is open and hingedly installed with a sealed double-leaf door.

[0087] In this embodiment, the dust collection part of the dust reduction mechanism is optimized. Specifically, an outer box body 91 connected to the installation box 82 is fixedly installed at the bottom of the installation box 82. This outer box body 91 is fixedly connected to the second base frame 51 to ensure its stability and reliability.

[0088] A collection box 92 for collecting dust is provided inside the outer box 91. Since the filter 85 inside the box 82 filters the extracted air, the dust trapped by the filter 85 will fall into the collection box 92. As time goes by, the dust in the collection box 92 accumulates and needs to be cleaned regularly. To facilitate the cleaning and replacement of the filter 85, one side of the outer box 91 is designed to be open and has a hinged sealed double-leaf door. In this way, when the filter needs to be cleaned or replaced, the staff can open the sealed double-leaf door, remove the collection box 92 and the filter 85, and perform the cleaning or replacement operation.

[0089] In addition, the design of the outer box 91 also takes into account the sealing and collection efficiency of dust. The connection between the outer box 91 and the installation box 82 adopts a sealed structure to ensure that dust does not leak from the connection. At the same time, the space inside the outer box 91 is of moderate size, which can accommodate enough dust without causing dust to fly due to excessive space. This improved dust collection part has the advantages of simple structure, easy operation, good sealing, and high collection efficiency. By regularly cleaning and replacing the filter 85, the continuous and effective operation of the dust reduction mechanism can be ensured, thereby maintaining a clean working environment and the health of the staff.

[0090] In another embodiment of the present invention, the screening mechanism 2 is further provided with a drying mechanism for air-drying the garbage in the drum screen 22, and the drying mechanism is used to reduce the debris adhered to the garbage in the drum screen 22, and the drying mechanism includes: a connecting air duct 93 fixedly connected to the exhaust port on the top of the mounting box 82; a mounting transverse pipe 94 fixedly connected to one end of the connecting air duct 93, the mounting transverse pipe 94 extends into the drum screen 22, and the end of the mounting transverse pipe 94 away from the connecting air duct 93 is in a closed state; a plurality of air nozzles 95 fixedly connected to the bottom of the mounting transverse pipe 94, for air-drying the garbage in the drum screen 22 to reduce the debris adhered to the garbage in the drum screen 22; a support rod 96 fixedly mounted on the first base frame 21, the support rod 96 being fixedly connected to the mounting transverse pipe 94 for supporting the mounting transverse pipe 94.

[0091] In this embodiment, the air-drying mechanism is used to further optimize the function of the screening mechanism 2, particularly by reducing the amount of debris adhering to the drum screen 22 during waste processing. This design not only improves screening efficiency but also helps reduce difficulties in subsequent processing. The air-drying mechanism works in conjunction with the dust suppression mechanism, fully utilizing the kinetic energy of the fan 80 within the dust suppression mechanism and reducing energy consumption.

[0092] Specifically, when screening mechanism 2 is operating, fan 80 within mounting box 82 not only draws air for dust reduction but also delivers some air into drum screen 22 via connecting air duct 93 and mounting cross pipe 94. Airflow ejected through air nozzles 95 dries the waste within drum screen 22, thereby reducing the amount of debris adhering to the waste. This drying mechanism design offers the advantages of simple structure, easy operation, and significant reduction in the amount of debris adhering to the waste, effectively improving the processing efficiency and effectiveness of screening mechanism 2.

[0095] Compared with the related art, the stale garbage and decoration garbage classification and processing device provided by the present invention can perform double crushing of decoration garbage through the crushing equipment set up, thereby improving the crushing effect and efficiency of decoration garbage, being beneficial to the subsequent reuse of decoration garbage, and reducing the pollution of dust to the environment by setting up a dust reduction mechanism. In particular, the air drying mechanism and the optimized dust collection part equipped in the device not only reduce the debris adhering to the garbage and improve the screening effect, but also effectively collect the dust generated during the processing process, improve the working environment, and protect the health of the staff.
