Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and more specifically, to a waste screening device for aging in landfills. Background Technology

[0002] Stale waste usually refers to waste that has been landfilled or buried for many years. After a long period of natural decomposition and stabilization, the odor has basically disappeared and the properties are relatively stable. When stale waste needs to be processed, screening equipment is usually used to screen it to facilitate processing. Drum screening equipment is a type of screening equipment commonly used to process stale waste.

[0003] In the existing technology, when sorting aged waste, some of the aged waste has a high moisture content. When the moisture content of the waste is too high, the waste particles may stick together due to increased viscosity and adhere to the screen, resulting in a decrease in screening efficiency. At the same time, the wet and sticky waste particles are easy to clog the screen holes, which hinders the screening process and further reduces the screening efficiency. Utility Model Content

[0011] The technical effects and advantages of this utility model of a waste aging screening device for landfills:

[0012] The motor drives the long rod and gears to rotate, which in turn drives the gear ring and the rotating drum to rotate together. As the drum rotates, it screens the aged waste inside. The rotation of the long rod drives the round rod, the first pulley, the transmission belt, the second pulley, the rotating rod, and the fan blades to rotate, causing the fan blades to generate a unidirectional airflow. By installing a heating plate, the airflow generated by the fan blades can be heated. The hot air blown out of the air duct is blown into the ventilation chamber of the rotating drum. After the hot air enters the ventilation chamber, it gradually heats the inner wall of the rotating drum, causing some of the moisture in the waste to evaporate. After the moisture inside the aged waste evaporates, the viscosity decreases, which can effectively prevent the aged waste from adhering to the first and second round holes. This is more conducive to screening aged waste with high moisture content and solves the problem of excessive moisture content in some aged waste. Attached Figure Description

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.

[0024] Example 1

[0025] Reference Figure 1-8A waste screening device for landfill aging includes a base platform 1, a support plate 2 fixedly connected to the top of the base platform 1, a rotating drum 3 rotatably connected to the top of the support plate 2, a first circular hole at the top of the outer wall of the rotating drum 3, and a second circular hole at the bottom of the outer wall of the rotating drum 3, the diameter of the first circular hole being smaller than that of the second circular hole. A mounting plate 4 is fixedly connected to one side of the support plate 2, a motor 5 is fixedly connected to one side of the mounting plate 4, a long rod 6 is fixedly connected to the output end of the motor 5, a gear 7 is fixedly connected to the outer wall of the long rod 6, a gear ring 8 is fixedly connected to the outer wall of the rotating drum 3, a support column 9 is fixedly connected to the top of the base platform 1, and a first conveyor belt 10 is disposed at the top of the support column 9 and positioned on the rotating drum. At the top of the inner wall of the 3, a support plate 11 is fixedly connected to one side of the support column 9, a round rod 13 is fixedly connected to one end of the long rod 6, a first pulley 12 is fixedly connected to one end of the round rod 13, the first pulley 12 is rotatably connected to one side of the support plate 11, a transmission belt 14 is sleeved on the outer wall of the first pulley 12, a second pulley 15 is sleeved on one side of the inner wall of the transmission belt 14, the second pulley 15 is rotatably connected to one side of the support plate 11, a rotating rod is fixedly connected to one side of the second pulley 15, a fan blade 16 is fixedly connected to the outer wall of the rotating rod, a wind duct 17 is fixedly connected to one side of the top of the support plate 11, a heating plate 18 is fixedly connected to the inner wall of the wind duct 17, and a ventilation cavity is opened inside the rotating cylinder 3.

[0026] To address the issue of excessive moisture content in some aged waste, when screening is required, the aged waste can be conveyed to the top of the inner wall of the rotating drum 3 via the first conveyor belt 10. The motor 5 then drives the long rod 6 and gear 7 to rotate. The rotation of gear 7 causes the gear ring 8 and the rotating drum 3 to rotate together. As the drum 3 rotates, it screens the aged waste inside. Smaller pieces of waste are screened out through the first circular hole, while larger pieces are screened out through the second circular hole. The rotation of the long rod 6 drives the circular rod 13 on one side and the first pulley 12 to rotate. The rotation of the first pulley 12 then drives the transmission belt 14. The second pulley 15 rotates, which in turn drives the rotating rod and fan blade 16 to rotate, causing the fan blade 16 to generate wind force to one side. By setting the heating plate 18, the airflow generated by the fan blade 16 can be heated. The hot air blown out of the air duct 17 will blow into the ventilation cavity of the rotating cylinder 3. After the hot air enters the ventilation cavity, it will gradually heat the inner wall of the rotating cylinder 3. When the aged waste with a high water content enters the heated rotating cylinder 3, some of the water will evaporate. After the water inside the aged waste evaporates, its viscosity will decrease, thereby preventing the aged waste from adhering to the first and second round holes, which is more conducive to screening the aged waste with a high water content.

[0027] Reference Figure 6A support ring 19 is fixedly connected to the top of the inner wall of the rotating cylinder 3. A connecting ring 20 is rotatably connected to the inner wall of the support ring 19. The connecting ring 20 is fixedly connected to one side of the air duct 17. The inner wall of the connecting ring 20 is connected to the inner wall of the air duct 17.

[0028] By setting a support ring 19 on the rotating drum 3, it is convenient to install the connecting ring 20 on one side of the ventilation cavity. The connecting ring 20 can provide a sealing effect for the top of the ventilation cavity, preventing garbage from falling into the ventilation cavity. At the same time, the connecting ring 20 is fixed on one side of the air duct 17, so that the connecting ring 20 can be kept fixed when the ventilation cavity rotates, which makes it easy for the hot air blown out of the air duct 17 to be evenly transferred into the ventilation cavity.

[0029] Reference Figure 1 A second conveyor belt 21 is provided at the top of the base platform 1, and a guard plate 22 is fixed to one side of the base platform 1. The guard plate 22 is provided at the bottom of the second conveyor belt 21.

[0030] By setting two sets of second conveyor belts 21 above the base platform 1, the aged waste screened through the first and second round holes can be transported separately. By setting the guard plate 22, it is beneficial to provide a limiting effect on both sides of the two sets of second conveyor belts 21.

[0031] Reference Figure 8 A fixing block 23 is fixedly connected to the top of one side of the pallet 2, and a scraper 24 is fixedly connected to one side of the fixing block 23. The scraper 24 is attached to the outer wall of the rotating drum 3.

[0032] By setting a fixing block 23 and a scraper 24 at the top of the tray 2, the scraper 24 can be used to scrape off the garbage stuck to the outer wall of the drum 3 when the drum 3 rotates, thus preventing the garbage from adhering to the outer wall of the drum 3.

[0033] Reference Figure 8 A pad 25 is fixedly connected to one side of the scraper 24, and the pad 25 is made of sponge.

[0034] By providing a sponge pad 25 on one side of the scraper 24, it is convenient to wipe the outer wall of the rotating drum 3 after scraping the outer wall of the rotating drum 3.

[0035] Reference Figure 8 A side plate 26 is fixedly connected to one side of the pallet 2, and a cleaning plate 27 is fixedly connected to one side of the side plate 26. The cleaning plate 27 is disposed on one side of the inner wall of the rotating drum 3.

[0036] By installing a side plate 26 and a cleaning plate 27 on the tray 2, it is easy to scrape off the garbage attached to the inner wall of the drum 3 when the drum 3 rotates.

[0037] Working Principle: To address the issue of excessive moisture content in some aged waste, when screening is required, the aged waste is conveyed to the top of the inner wall of the rotating drum 3 via the first conveyor belt 10. The starting motor 5 drives the long rod 6 and gear 7 to rotate. When the gear 7 rotates, it drives the gear ring 8 and the rotating drum 3 to rotate together. As the rotating drum 3 rotates, it screens the aged waste inside. Smaller waste is screened out through the first circular hole, and larger waste is screened out through the second circular hole. The rotation of the long rod 6... The rotating rod 13 and the first pulley 12 on one side rotate. When the first pulley 12 rotates, it drives the transmission belt 14 and the second pulley 15 to rotate. The second pulley 15 then drives the rotating rod and the fan blade 16 to rotate, causing the fan blade 16 to generate wind force to one side. By setting the heating plate 18, the airflow generated by the fan blade 16 can be heated. The hot air blown out of the air duct 17 will be blown into the ventilation cavity of the rotating cylinder 3. By setting the support ring 19 on the rotating cylinder 3, it is convenient to install the connecting ring 20 on one side of the ventilation cavity. The connecting ring 20 can provide a sealing effect for the top of the ventilation cavity. To prevent garbage from falling into the ventilation cavity, the connecting ring 20 is fixed to one side of the air duct 17. This allows the connecting ring 20 to remain fixed while the ventilation cavity rotates, facilitating the even distribution of hot air blown from the air duct 17 into the ventilation cavity. Once inside the ventilation cavity, the hot air gradually heats the inner wall of the rotating drum 3. When the aged garbage with high moisture content enters the heated rotating drum 3, some of the moisture evaporates. After evaporation, the viscosity of the aged garbage decreases, preventing it from adhering to the first and second round holes. This is more beneficial for processing aged garbage with high moisture content. The aged waste is screened. When the rotating drum 3 rotates, the scraper 24 can easily scrape off the waste sticking to the outer wall of the rotating drum 3, preventing the waste from adhering to the outer wall of the rotating drum 3. The pad 25 can wipe the outer wall of the rotating drum 3. The cleaning plate 27 can scrape off the waste adhering to the inner wall of the rotating drum 3. By setting two sets of second conveyor belts 21 above the base platform 1, the aged waste screened through the first and second round holes can be transported separately. By setting the guard plate 22, it can help to provide a limiting effect on both sides of the two sets of second conveyor belts 21 to prevent the waste from falling out.

[0038] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
