Description

Technical Field

[0001] This utility model relates to the field of municipal solid waste treatment, and in particular to an automatic sorting and treatment device for municipal solid waste. Background Technology

[0002] Municipal solid waste management refers to a series of activities including the collection, transportation, and disposal of waste generated in daily life to reduce its harm to the environment and achieve resource recycling. There are various methods, the most common being sanitary landfill, which involves burying waste underground for microbial decomposition; incineration, which uses high temperatures to burn waste, generating electricity but requiring pollution control; and composting, which converts organic waste into fertilizer. Effective municipal solid waste management is of great significance, not only preventing soil, water, and air pollution caused by indiscriminate dumping of waste, but also enabling the recovery of usable resources from waste, such as metals and paper, promoting resource recycling and facilitating the coordinated development of the economy and the environment.

[0003] However, current automatic sorting and processing equipment for municipal solid waste has the following drawbacks: Waste tends to clump together during processing, which negatively impacts subsequent sorting operations and reduces sorting efficiency. Furthermore, when electromagnets attract metal objects, the metal tends to stick to them, affecting subsequent magnetic attraction and leading to decreased sorting efficiency.

[0004] In response to this technical problem, this application proposes an automatic sorting and processing device for municipal solid waste. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 This utility model provides an embodiment of an automatic sorting and processing device for household waste, comprising a housing 2. Two rotating rods 11 are rotatably connected to the top side of the housing 2. Multiple stirring blades 12 for breaking up clumps of waste are fixedly connected to the outer wall of each rotating rod 11. The rotating rods 11 drive the stirring blades 12 to rotate, thereby breaking up the waste. The two rotating rods 11 are connected by a transmission assembly to allow them to rotate in opposite directions. Magnetic suction components for separating metal objects from the waste are provided on both the left and right sides of the housing 2. A device for separating lightweight materials from the waste is provided on the bottom side of the housing 2. The separation component includes a first collection box 9 located on the bottom side of the inner side of the box 2 for collecting the remaining waste after separation. A gear 8 is fixedly connected to the right end of the rotating rod 11. The gear 8 is rotatably connected to the right side of the outer wall of the box 2. The two gears 8 mesh with each other, and the two meshing gears 8 rotate in opposite directions, so that the stirring blade 12 can break up the waste. A motor 3 is installed on the left side of the box 2. The drive end of the motor 3 is fixedly connected to the left end of the front rotating rod 11, and the motor 3 drives the front rotating rod 11 to rotate. A feed trough 1 for adding waste is fixedly connected to the top side of the box 2.

[0026] Reference Figures 3-5 Magnetic boxes 7 are fixedly connected to both the left and right sides of the box 2. Magnetic openings are provided on both sides of the box 2. An electromagnet 13 is fixedly connected inside the magnetic box 7. Second collection boxes 6 for collecting metal are fixedly connected to the bottom of both sides of the box 2. The electromagnet 13 is energized during magnetic attraction, giving it a strong magnetic force that attracts metal objects. When it is necessary to collect the metal objects from the electromagnet 13, the power can be turned off to demagnetize it, causing the metal objects to fall into the second collection box 6 by gravity. A scraper 14 is slidably connected inside the magnetic box 7. The scraper 14 scrapes the metal objects stuck to the electromagnet 13, allowing them to fall into the second collection box 6 for collection. To prevent metal objects from sticking to the electromagnet 13 and affecting subsequent magnetic attraction, the front and rear ends of the scraper 14 are rotatably connected to limit rods 15. Two limit blocks 16 are fixedly connected to the front and rear sides of the magnetic attraction box 7. The limit rods 15 are engaged between the left and right limit blocks 16. By engaging the limit rods 15 between the left and right limit blocks 16, the position of the scraper 14 is fixed. A blower 10 is installed on the rear side of the box body 2. A through groove is opened on the front side of the box body 2. A baffle box 5 for preventing garbage from being blown away is fixedly connected to the front side of the through groove. A third collection box 4 for collecting lightweight garbage is set on the bottom front side of the box body 2. The blower 10 blows the lightweight garbage in the garbage into the through groove and allows the lightweight garbage to reach the baffle box 5 through the through groove, so that the lightweight garbage falls into the third collection box 4 under the action of gravity for collection.

[0027] Working principle: First, start motor 3 and energize electromagnet 13. Driven by motor 3, the front rotating rod 11 rotates, which in turn drives the rear rotating rod 11 to rotate through two meshing gears 8, causing the two rotating rods 11 to rotate in opposite directions. Then, the garbage is poured into the box 2 through the feed chute 1. Some larger clumps of garbage will pass between the two rotating rods 11. Under the action of the two sets of relatively rotating stirring blades 12, these larger clumps of garbage will be broken up to facilitate subsequent sorting. The garbage will then continue to fall downwards. When it falls into the magnetic suction port, the energized electromagnet 13 will attract any metal objects mixed in with the garbage. The remaining garbage will then continue to fall downwards. When this garbage falls into the blower... When the blower 10 is between the channel and the trough, the blower 10 will blow the light waste in the waste and make the light waste pass through the channel to the baffle box 5. The light waste will fall into the third collection box 4 under the action of gravity for collection. The remaining waste will fall into the first collection box 9 on the bottom plate of the box body 2. When it is necessary to collect the metal objects attracted on the electromagnet 13, the power can be turned off to make the electromagnet 13 lose its magnetic force, and then the metal objects on the electromagnet 13 will fall into the second collection box 6 by gravity. The scraper 14 will scrape off the metal objects stuck to the electromagnet 13 and make them fall into the second collection box 6 for collection. The scraper 14 can be slid by moving the limit rod 15 upward and rotating the limit rod 15 to make it separate from the limit block 16.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
