Description

Technical Field

[0001] The present invention relates to the technical field of garbage crushing, and in particular provides a municipal garbage processing device. Background Art

[0002] In today's society, waste disposal has become a vital environmental task. The separation and collection of waste after separation has significant benefits.

[0003] From a resource recovery perspective, waste sorting and shredding effectively separates recyclable materials like metals, plastics, and paper, increasing recycling rates and reducing resource waste. For example, shredded metals are easier to smelt and purify, while plastics can be re-pelletized. From an environmental perspective, separating hazardous waste like used batteries and expired medicines prevents soil and water pollution and reduces environmental risks. Furthermore, shredded waste reduces its volume, facilitating subsequent transportation and landfill, reducing landfill space.

[0004] However, existing municipal waste treatment equipment has obvious drawbacks. Currently, most equipment relies on manual labor to sort different types of garbage, which is not only labor-intensive, but also has low efficiency and poor accuracy in manual sorting. Manual labor is prone to fatigue after long hours of work, resulting in an increase in the error rate of classification. After the classification is completed, different types of garbage need to be crushed and collected separately, which further increases the processing links and time costs. The entire processing process is cumbersome, which seriously affects the efficiency of garbage disposal and makes it difficult to meet the growing demand for garbage disposal. Therefore, the development of a device that can automatically realize garbage sorting, crushing and classified collection is of urgent practical significance. Summary of the Invention

[0016] The embodiments of the present invention have the following advantages.

[0017] When municipal waste is crushed and sorted by a municipal waste treatment device, first, the municipal waste is fed into the upper end of the feed part through the feeding equipment, and the municipal waste inside is guided to the drain component through the feed part. The water-containing waste is drained when passing through the drain component, and then the drain component realizes the function of draining most of the water in the waste. Subsequently, the waste after preliminary draining is discharged from the output end of the drain component to the input end of the eddy current separator. When the eddy current separator is working, a magnetic field is generated in the metal in the waste, and then a repulsive force is formed between the magnetic field of the separator and the metal, and the metal is thrown away from the surface of the eddy current separator. When the eddy current separator drives the waste to move on its surface During the process, the metal is separated by the eddy current separator, so that the metal finally falls into the first crushing part for crushing. At the same time, when the non-metallic domestic waste moves to the side of the evaporation part on the surface of the eddy current separator, the non-metallic domestic waste cannot be affected by the eddy current separator to generate magnetic force, so that the non-metallic domestic waste falls into the evaporation part when it reaches the side of the eddy current separator. When the evaporation part is working, it further dries the non-metallic domestic waste to remove moisture. When the non-metallic domestic waste comes out of the evaporation part, it falls from the output end of the evaporation part into the second crushing part due to the influence of gravity. Then the second crushing part crushes the non-metallic domestic waste, and the crushed non-metallic domestic waste enters the second crushing part from the output end of the second crushing part. The waste is then sorted and stored in a non-metallic domestic waste collection box. Since the high-speed airflow channel of the light waste sorting section passes between the upper part of the second crushing section and the output end of the evaporation section, when the non-metallic domestic waste falls into the second crushing section, the light waste will be carried by the high-speed airflow into the third crushing section for crushing, such as paper scraps, plastic bags, etc. After being crushed by the third crushing section, the light waste is finally discharged into the light waste collection box for collection, thereby realizing the function of classifying and crushing domestic waste. The waste is first drained to remove surface moisture, and then deeply dried by the evaporation section, which greatly reduces the moisture content of the material, reduces the phenomenon of wet waste adhering to the cutter, and improves the crushing efficiency. The eddy current separator is used Separate metals before crushing to avoid metal fragments from mixing into subsequent crushing links, reduce the impact load of the tool, and extend the life of the equipment. Metal, non-metal, and light garbage are sorted before crushing to ensure that the crushing particle size of garbage of different materials is more uniform. Light garbage (such as plastic bags and paper scraps) enters the third crushing section after being sorted by high-speed airflow to avoid light objects from entangled with the tool or contaminating other materials, thereby improving the uniformity of crushing. Targeted crushing is carried out after sorting to reduce wear and energy consumption. Drainage and evaporation drying pre-treatment are performed to improve the crushing stability. The product purity after material-based crushing is high and can directly enter the recycling production line to avoid mixed crushing pollution. The sorted materials can be directly used for recycling manufacturing (such as metal recycling and plastic granulation).

DETAILED DESCRIPTION

[0026] In order to make the purpose, scheme and advantages of the technical solution of the present invention more clear, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. Unless otherwise specified, the terms used herein have the common meanings in the art. The same reference numerals in the drawings represent the same components.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] As described above, in traditional municipal waste treatment equipment, the inability to automatically sort waste, classify and crush different types of waste, and collect them separately leads to low waste treatment efficiency.

[0029] In order to at least partially solve the above-mentioned problems and one or more of other potential problems, an exemplary embodiment of the present invention provides a municipal waste treatment device, which includes: a frame 100 and a feed part 200, the feed part 200 is arranged at the feed end of the frame 100; a drain component 300, the feed port of the drain component 300 is toward the discharge end at the lower part of the feed part 200; an eddy current separator 500, the eddy current separator 500 is arranged on one side of the feed part 200, the input end of the eddy current separator 500 is connected to the output end of the drain component 300; a first crushing part 400, the feed end is connected to the output end of the eddy current separator 500, and the output end of the first crushing part 400 is connected to a metal collecting Collecting box 430; evaporation section 700, the input end is arranged at the output end of eddy current separator 500, and the input end is arranged at one side of the output end of eddy current separator 500; second crushing section 600, the feed end of the second crushing section 600 is arranged at the lower part of the output end of evaporation section 700; non-metallic domestic waste collection box 630, connected to the output end of the second crushing section 600; light waste sorting section 800, the light waste sorting section 800 includes: a high-speed airflow channel 810, the high-speed airflow channel 810 passes through the feed end of the second crushing section 600; a third crushing section 820, arranged at the output end of the high-speed airflow channel 810; a light waste collection box 824, arranged at the output end of the third crushing section 820.

[0030] In the above embodiment, when municipal waste is crushed and sorted by the municipal waste treatment device, first, the municipal waste is fed into the upper end of the feed part 200 through the feeding equipment, and the municipal waste inside it is guided to the drain component 300 through the feed part 200. The water-containing waste is drained when passing through the drain component 300, and then the function of draining most of the water in the waste is achieved through the drain component 300. Subsequently, the waste after preliminary draining is discharged from the output end of the drain component 300 to the input end of the eddy current separator 500. When the eddy current separator 500 is working, a magnetic field is generated in the metal in the waste, and then a repulsive force is formed between the magnetic field of the separator and the metal, and the metal is thrown away from the surface of the eddy current separator 500. When the eddy current separator 500 is working, a magnetic field is generated in the metal in the waste, and then a repulsive force is formed between the magnetic field of the separator and the metal, and the metal is thrown off the surface of the eddy current separator 500. In the process of the separator 500 driving the garbage to move on its surface, the metal is separated by the eddy current separator 500, so that the metal finally falls into the first crushing part 400 for crushing. At the same time, when the non-metallic domestic garbage moves on the surface of the eddy current separator 500 to the side of the evaporation part 700, since the non-metallic domestic garbage cannot be affected by the eddy current separator 500 to generate magnetic force, the non-metallic domestic garbage falls into the evaporation part 700 when it reaches the side of the eddy current separator 500. When the evaporation part 700 is working, it further dries the non-metallic domestic garbage to remove moisture. After the non-metallic domestic garbage comes out of the evaporation part 700, it falls from the output end of the evaporation part 700 due to gravity, and then the second crushing part 600 The non-metallic domestic waste after crushing enters the non-metallic domestic waste collection box 630 from the output end of the second crushing part 600 for storage. Since the high-speed air flow channel 810 of the light waste sorting part 800 passes between the upper part of the second crushing part 600 and the output end of the evaporation part 700, when the non-metallic domestic waste falls into the second crushing part 600, the light waste will be carried by the high-speed air flow into the third crushing part 820 for crushing, such as paper scraps, plastic bags, etc. The light waste crushed by the third crushing part 820 is finally discharged into the light waste collection box 824 for collection, thereby realizing the function of classifying and crushing domestic waste. The garbage first passes through the drain component 300 to remove surface moisture, and then passes through the evaporation part 700. Deep drying significantly reduces the moisture content of materials, reduces the phenomenon of wet garbage sticking to the cutter, and improves crushing efficiency. The eddy current separator 500 is used to separate metals before crushing to prevent metal fragments from mixing into subsequent crushing links, reduce the impact load on the cutter, and extend the life of the equipment. Metal, non-metal, and light garbage are sorted before crushing to ensure that the crushing particle size of garbage of different materials is more uniform. Light garbage (such as plastic bags and paper scraps) enters the third crushing section 820 after being sorted by high-speed airflow to prevent light objects from entangled with the cutter or contaminating other materials, thereby improving crushing uniformity. Targeted crushing after sorting reduces wear and energy consumption. Drainage and evaporation drying pretreatment improve crushing stability. The product purity after material-based crushing is high and can directly enter the recycling production line to avoid mixed crushing pollution.The sorted materials can be directly used for recycling (such as metal recycling and plastic granulation).

[0031] See also Figure 1-Figure 5 In some embodiments, the feed part 200 includes: a feed box 201, which is arranged on the upper part of the drainage component 300; at least two groups of rolling rollers 202 are provided, and the two groups of rolling rollers 202 are arranged in parallel in the feed box 201; wherein there is a gap between the two groups of rolling rollers 202; a first motor 203, the first motor 203 is arranged on the outer wall of the feed box 201, and the output shaft of the first motor 203 passes through the outer wall of the feed box 201 and is driven and connected to the two groups of rolling rollers 202; the feed end of the feed box 201 is set upward, and the discharge end is set toward the drainage component 300 at the bottom.

[0032] In the above embodiment, the feed box 201 is used to collect various domestic wastes provided by the feeding equipment, so that after the domestic waste enters the feed box 201, it is crushed by the crushing roller 202 provided in the feed box 201, thereby reducing the size of the domestic waste. The crushing efficiency of the subsequent crushing equipment is improved by the initial crushing, and the garbage disposal device is prevented from being blocked by large pieces of garbage. At the same time, when the crushing roller 202 is crushed, the kitchen waste packaged in the packaging box, packaging bag, etc. can also be crushed, so that the kitchen waste containing a large amount of sewage can be squeezed out of the packaging box or packaging bag. In order to reduce the water content in the garbage, when the rolling roller 202 is rolling, the first motor 203 is started, so that the output shaft of the first motor 203 drives the two rolling rollers 202 to rotate on the inner wall of the feed box 201, and then the garbage dropped between the rolling rollers 202 is rolled by the two rolling rollers 202 rotating in the same direction. A large amount of sewage flows from the output end of the feed box 201 to the drain component 300 for draining, and then enters the eddy current separator 500 for metal garbage sorting after the drainage component 300 drains, avoiding sewage from entering the eddy current separator 500. This causes the eddy current separator 500 to malfunction, and a large amount of wet garbage adheres to the main body of the eddy current separator 500. After the garbage enters the feed box 201, it is crushed by the crushing roller 202, and large pieces of garbage (such as packaging boxes, furniture fragments) are crushed and reduced in size to a size suitable for subsequent processing, avoiding clogging of downstream equipment (such as drain components 300, separators). During the crushing process, closed packaged wet garbage (such as kitchen waste bags, beverage bottles) is squeezed and the internal sewage is released in advance and discharged into the drain component 300 through the bottom of the feed box 201 for centralized treatment, reducing the overall content of garbage. The amount of water is reduced, and the subsequent drainage load is reduced. At the same time, it is prevented that wet garbage sticks to the surface of the sorting machine (for example, the eddy current sorting machine 500 fails to separate metals due to excessive humidity). The compacted garbage is dehydrated for the second time by the drainage component 300 and then enters the sorting link, forming a double dehydration chain of "crushing pre-dehydration → draining deep dehydration" to ensure the dry operation of the sorting machine. The crushing pre-crushing reduces the volume and reduces the risk of blockage. The crushing squeezes and releases the sewage in the package, which improves the dehydration rate. The pre-crushing reduces the load of the subsequent crusher and reduces the overall energy consumption. The crushing forces the bag to break, releases the internal garbage, and improves the sorting purity.

[0033] See also Figure 1-Figure 5In some embodiments, the drain assembly 300 includes: a drain end 310 and an extrusion end 320, the drain end 310 is arranged at the lower part of the feed part 200, and the extrusion end 320 is arranged close to the eddy current separator 500; it also includes: a connecting rod assembly 330, the two ends of the connecting rod assembly 330 respectively drive and connect the drain end 310 and the extrusion end 320; the drain end 310 includes: a drain plate 311, the cross-section of the drain plate 311 is U-shaped, and the drain plate 311 is arranged at the lower part of the output end of the feed part 200; a spring 312, which is provided in plurality, and the two ends of the plurality of springs 312 are respectively connected to the drain plate 311 and the feed box 201; wherein the end of the drain plate 311 close to the input end of the eddy current separator 500 is arranged tilted downward.

[0034] In the above embodiment, the drain assembly 300 is composed of a drain end 310, an extrusion end 320 and a connecting rod assembly 330. The connecting rod assembly 330 is used to simultaneously drive the drain assembly 300 to shake, and drive the extrusion end 320 to continuously squeeze the garbage discharged from the drain plate 311 for dehydration. The spring 312 realizes the installation function of the drain plate 311. When the connecting rod assembly 330 drives the drain plate 311 to shake, the spring 312 can amplify the shaking effect and shake off the moisture in the garbage in the drain plate 311.

[0035] See also Figure 1-Figure 5 In some embodiments, the extrusion end 320 includes: an extrusion bin 321, which is U-shaped, one end of the extrusion bin 321 is arranged at the lower part of the drain plate 311, and the other end is arranged at the upper part of the input end of the eddy current separator 500; an extrusion plate 322, which is arranged to slide vertically along the inner wall of the extrusion bin 321; a mesh plate 323, which is arranged on the inner bottom surface of the extrusion bin 321 and is spaced from the inner bottom surface of the extrusion bin 321; a guide bin 324, which is arranged between the mesh plate 323 and the inner surface of the extrusion bin 321, and the water outlet of the guide bin 324 is arranged horizontally toward the drain plate 311; a push plate 325, which is arranged in the extrusion bin 321 and slides horizontally along the inner wall of the extrusion bin 321; wherein the connecting rod assembly 330 is used to drive the push plate 325 to slide back and forth horizontally in the extrusion bin 321, and drive the extrusion bin 321 to move back and forth vertically.

[0036] In the above embodiment, when the connecting rod assembly 330 is running, the squeezing plate 322 is pushed to intermittently squeeze the garbage in the squeezing bin 321, so that the garbage in the squeezing bin 321 is squeezed and the water involved in the drainage plate 311 is squeezed through the mesh plate 323 into the diversion bin 324, and then the water is diverted and collected through the diversion bin 324. It is worth mentioning that a first flushing pipe is also provided on the upper part of the feed box 201. The first flushing pipe is used to flush the grinding roller 202 in the feed box 201, thereby improving the garbage from easily adhering to the grinding roller 202. The drain plate 311 is provided with a second flushing pipe on the upper part of the drain plate 311. The second flushing pipe is arranged at the upper center of the drain plate 311. The second flushing pipe evenly flushes water toward the inner wall of the U-shaped structure of the drain plate 311, so that the garbage in the drain plate 311 can be flushed, and the dirt adhering to the garbage is washed away and separated from the water through the drain plate 311. At the same time, the drain plate 311 can be cleaned by the second flushing pipe. A guide plate is provided at the lower part of the drain plate 311 to guide the water. One end of the flow plate is set close to the top of the push plate 325, and the other end is tilted downward. The sewage after flushing is collected after being guided by the guide plate, removing the dirt adhered to the garbage and improving the problem of strong odor of the garbage. When the extrusion plate 322 is pushed by the connecting rod assembly 330 for extrusion, the extrusion plate 322 is lifted up, and then the connecting rod assembly 330 pushes the push plate 325 to move in the extrusion chamber 321, so that the extruded garbage can be pushed to the side of the extrusion chamber 321 through the push plate 325 and fall into the eddy current separator 500 for metal sorting. 311+extrusion plate 322 forced extrusion improves the dehydration rate, cleans the rolling roller 202 and the drain plate 311 in real time, reduces the risk of adhesion and rust, pre-dehydrates + pushes dry garbage to ensure the dry operation of the sorting machine, flushing + diversion quickly separates sewage and solid waste, reduces organic matter fermentation, connecting rod drives coordinated extrusion and pushing to achieve fully automatic continuous operation, flushing sewage is recycled and processed through the guide plate to avoid secondary pollution and extend the life of the equipment, and the garbage after squeezing and dehydration is directly pushed to the sorting machine to reduce energy consumption and failure points in the intermediate transfer link.

[0037] See also Figure 1-Figure 5In some embodiments, the connecting rod assembly 330 includes: a second motor 3301, arranged on the frame 100; a first eccentric plate 3302, provided on the output shaft of the second motor 3301; a first connecting rod 3303, one end of which is rotatably connected to the first eccentric plate 3302, and the first connecting rod 3303 is eccentrically connected to the first eccentric plate 3302; a second connecting rod 3304, one end of which is hinged to the end of the first connecting rod 3303 away from the first eccentric plate 3302; a first L-shaped rod 3305, one end of which is rotatably connected to the second connecting rod 3304 away from the end of the first connecting rod 3303, and the other end is hinged to the outer wall of the push plate 325; a second L-shaped rod 3306, one end of which is rotatably connected to the circumferential outer wall of the first connecting rod 3303 close to the end of the second connecting rod 3304; wherein the corner of the second L-shaped rod 3306 is rotatably set on the frame 100; a third connecting rod 3307, one end of which is rotatably connected to the second L-shaped rod The rod 3306 is away from one end of the first L rod 3305; the fourth connecting rod 3308, one end of which is rotatably connected to the other end of the third connecting rod 3307; the push rod 3309, the bottom end of which is connected to the surface of the extrusion plate 322, and the top end is hinged to the other end of the fourth connecting rod 3308; the U-shaped rod, both ends of which are arranged on the upper part of the extrusion bin 321, and the U-shaped rod opening is facing downward; the middle section of the push rod 3309 passes through the top surface of the U-shaped rod; the pulley 3310 is rotatably installed on the frame 100; the second eccentric plate 3311 is arranged on one side of the pulley 3310; the fifth connecting rod 3312, one end of which is eccentrically connected to the surface of the second eccentric plate 3311, and the fifth connecting rod 3312 is rotatably connected to the second eccentric plate 3311; the other end of the fifth connecting rod 3312 is rotatably connected to the edge of the drain plate 311; the first transmission belt 3313 is wound around the pulley 3310 and the outer wall of the output shaft of the second motor 3301.

[0038] In the above embodiment, when the output shaft of the second motor 3301 rotates, the pulley 3310 is driven to rotate via the first transmission belt 3313, which in turn drives the second eccentric plate 3311 connected to the pulley 3310 to rotate, causing one end of the fifth connecting rod 3312 to perform a circular motion around the second eccentric plate 3311, while the other end pulls the drain plate 311 to continuously vibrate. At the same time, the rotation of the output shaft of the second motor 3301 drives the first eccentric plate 3302 to rotate. When the first eccentric plate 3302 rotates, it drives one end of the first connecting rod 3303 eccentrically connected to it to perform circular motion, so that the first connecting rod 3303 pulls the second connecting rod 3304 at the other end to move. Then, the second connecting rod 3304 drives the first L-shaped rod 3305 to move back and forth. As a result, the first L-shaped rod 3305 drives the push plate 325 to move intermittently back and forth, pushing the squeezed and dehydrated garbage into the eddy current separator 500. At the same time, when the first L-rod 3305 moves, it will drive one end of the second L-rod 3306 to swing around the corner of the second connecting rod 3304, so that the other end of the second L-rod 3306 drives the third connecting rod 3307 to swing in an arc in the vertical direction, so that the bottom end of the third connecting rod 3307 continues to swing downward or upward close to the second L-rod 3306, and then drives the fourth connecting rod 3308 to swing. When the fourth connecting rod 3308 swings, it drives the push rod 3309 to move down the mountain. The fourth connecting rod 3308 is restricted to vertical sliding on the surface of the U-shaped rod, so that the push rod 3309 drives the extrusion plate 322 to reciprocate up and down in the extrusion bin 321 to squeeze the garbage, so that the garbage can be squeezed and dehydrated.

[0039] See also Figure 1-Figure 5 In some embodiments, the eddy current separator 500 includes: rollers 5001, at least two groups of which are installed on the frame 100 at intervals; a conveyor belt 5002, which is wound around the circumferential outer wall of each roller 5001; a permanent magnet roller 5003; a roller 5001 that rotates on the side of the evaporation unit 700; a second transmission belt 5004, which is wound around one of the rollers 5001 and the outer wall of the output shaft of the second motor 3301; a third motor 5005, which is arranged on the frame 100, and the output shaft of the third motor 5005 is driven to connect one end of the permanent magnet roller 5003; a third eccentric plate 5 006, arranged on the frame 100; the sixth connecting rod 5007, one end of which is eccentrically connected to the third eccentric plate 5006 for rotation; the pull rod 5008, one end of which is rotationally connected to the other end of the sixth connecting rod 5007; the limit block 5009, the middle section of the pull rod 5008 is slidably arranged in the limit block 5009, and the limit block 5009 is installed on the frame 100; the scraper 5010 is slidably arranged on the surface of the conveyor belt 5002, and the scraper 5010 is connected to the pull rod 5008 on the side close to the edge of the conveyor belt 5002; the third transmission belt 5011, both ends of which are respectively connected to the output shaft of the second motor 3301 and the third eccentric plate 5006 for transmission.

[0040] In the above embodiment, when the eddy current separator 500 is in operation, the second transmission belt 5004 transmits the output torque of the second motor 3301 to one of the rollers 5001. The roller 5001 rotates to drive the conveyor belt 5002 to move, so that the conveyor belt 5002 drives the garbage on the surface to move toward the permanent magnetic roller 5003 on the other side. The third motor 5005 is started, driving the permanent magnetic roller 5003 to rotate at high speed in the cavity of the roller 5001. The high-speed rotation generates an alternating magnetic field, which pushes the metal in the garbage into the first part for crushing. The non-metal is thrown into the evaporation part 700 due to the inertia, thereby achieving the separation of metal and non-metal. At the same time, the third transmission belt 5011 is driven to rotate by the output shaft of the second motor 3301, causing the third eccentric plate 5006 to rotate, and then driving the sixth connecting rod 5007 to perform circular motion near the end of the eccentric plate, thereby driving the pull rod 5008 to slide back and forth in the limit block 5009, so that the pull rod 5008 drives the scraper 5010 to push the garbage moved to the scraper 5010 attachment to the input end of the conveyor belt 5002. Since there is a gap between the scraper 5010 and the surface of the conveyor belt 5002, only small pieces of garbage are allowed to pass through. Large pieces of garbage will be pushed into the compression bin by the scraper 5010 and compressed repeatedly until they can pass through the gap between the scraper 5010 and the surface of the conveyor belt 5002, thereby preventing large pieces of garbage from clogging the subsequent work sections.

[0041] See also Figure 1-Figure 5 In some embodiments, the first crushing section 400 includes: a metal crusher 410, which is located at the lower part of the output end of the conveyor belt 5002; a first material guide pipe 420, one end of which is connected to the discharge port of the metal crusher 410 and the other end is connected to the metal collection box 430.

[0042] In the above embodiment, the metal crusher 410 crushes the metal sorted from the conveyor belt 5002. The main area of metal crushing is configured with high-strength wear-resistant materials to withstand metal impact. The blades are made of wear-resistant alloy and tear or hit the metal through high-speed rotation. The high-strength tool and high-power motor design can quickly crush various types of scrap metal, shorten the recycling cycle, support continuous operation, reduce manual intervention costs, and improve overall processing efficiency.

[0044] In the above embodiment, the evaporation part 700 is used to evaporate moisture from the non-metallic garbage, further making the non-metallic garbage drier and avoiding the problem of mold and breeding of harmful bacteria when the non-metallic garbage is collected after being crushed. When the garbage is pushed by the spiral conveyor roller 720 to move on the inner wall of the evaporation bin 710, the heating coil 730 heats the garbage so that the moisture on the surface of the garbage is heated and evaporated. After the water vapor rises, it encounters the condensation pipe 740 and condenses, and is diverted and collected through the top surface of the evaporation bin 710.

[0048] In the above embodiment, the fan 811 blows air to the pipeline 812, so that the air flow passes through the pipeline 812 and reaches the scattering roller 813. The air flow passes through the upper half of the surface of the scattering roller 813. When passing through the scattering roller 813, the air flow changes direction and moves downward, and then carries the light garbage passing through the scattering roller 813 and blows it to the upper open end of the crushing box 821. Finally, the light garbage is crushed by the hammer crusher 822, and the crushed light garbage is stored in the light garbage collection box 824.
