Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically an airflow-type lightweight material separation device for waste treatment. Background Technology

[0002] The waste disposal market utilizes waste to produce charcoal, tar, and gas. Basically, it involves sorting, recycling, and then processing. The most common processing method is landfill, but it is slow, requires a large amount of land, and is prone to secondary pollution of groundwater. Incineration is another option, but it causes significant air pollution and requires substantial investment. Air separation and sorting of waste can effectively recycle and utilize the resources in the waste, reduce environmental damage, and save land resources.

[0003] Chinese Patent No. CN222469799U discloses an industrial solid waste air separator, including an air separator housing. The upper end of the air separator housing has a feed inlet, and a conveyor belt for transporting industrial solid waste is installed at the feed inlet. Inside the air separator housing is a downward-sloping vibrating screen, the upper end of which is directly below the inner end of the conveyor belt. A first air separator fan is installed in the gap between the vibrating screen and the conveyor belt. Inside the air separator housing is a baffle plate located at the lowest end of the vibrating screen. This invention facilitates air separation of industrial solid waste and employs a secondary air separation process, resulting in better air separation effect and increased efficiency. The vibrating screen vibrates the falling heavy waste, allowing dust and impurities to pass through. The heavy waste rolls downwards along the inclined vibrating screen during vibration, facilitating discharge and further improving the air separation effect of solid waste.

[0004] The existing technical solutions described above have the following drawbacks: the waste is vibrated by a vibrating screen, and then the light materials in the waste are separated by a first air separator and a second air separator. However, the vibrating screen requires a vibrating motor to drive it, and both sets of air separators require independent drive motors. This results in the need to install multiple sets of motors in the device, and an excessive number of motors will increase the manufacturing cost of the device, thereby reducing the cost-effectiveness of the device. In view of the above situation, technical innovation is carried out on the basis of the existing airflow light material separation device for waste treatment. Utility Model Content

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.

[0021] Please see Figures 1-4An airflow-type lightweight material separation device for waste treatment includes a high-pressure blower 12. A motor 13 is fixedly mounted on the front side of the high-pressure blower 12. The output end of the motor 13 passes through the front side of the high-pressure blower 12 and is connected to an impeller inside the high-pressure blower 12. A second synchronous pulley 18 is mounted on the rear side of the high-pressure blower 12. A rotating shaft is fixedly connected between the second synchronous pulley 18 and the impeller inside the high-pressure blower 12. A synchronous belt 19 meshes with the outer side of the second synchronous pulley 18, and a first synchronous pulley 17 meshes with the inner side of the synchronous belt 19. A camshaft 22 is fixedly mounted on the front side of the first synchronous pulley 17. A screen plate 23 is mounted above the camshaft 22. A three-way pipe 14 is connected to the air outlet of the high-pressure blower 12. Two sets of air outlets of the three-way pipe 14 are respectively connected to second diversion pipes 1. The top air outlets of the first and second branch pipes 16 and 15 are respectively connected to the first air box 2 and the second air box 21. Two sets of support plates 24 are evenly placed on the left and right sides of the bottom of the sieve plate 23. Spring telescopic rods 25 are evenly fixed on the top of the support plates 24. The telescopic ends of the spring telescopic rods 25 are fixed at the bottom of the sieve plate 23. The bottom of the high-pressure blower 12 is equipped with a processing box 1. The first air box 2, the second air box 21 and the two sets of support plates 24 are all fixed inside the processing box 1. The sieve plate 23 is slidably placed inside the processing box 1. The impeller inside the high-pressure blower 12 is driven to rotate by the motor 13, thereby driving the second synchronous wheel 18 to rotate through the impeller inside the high-pressure blower 12. The second synchronous wheel 18 is driven to rotate by the same motor 13. The stepper belt 19 drives the first synchronous pulley 17 to rotate, which in turn drives the camshaft 22 to rotate. The camshaft 22 then drives the screen plate 23 to move up and down with the assistance of the spring telescopic rod 25. When the impeller inside the high-pressure blower 12 rotates, it inputs high-speed airflow into the three-way pipe 14. The high-pressure airflow then enters the first diversion pipe 15 and the second diversion pipe 16 through the three-way pipe 14, and then enters the first air box 2 and the second air box 21 through the first diversion pipe 15 and the second diversion pipe 16 respectively. The camshaft 22 is rotatably mounted inside the processing box 1. The rear side of the camshaft 22 penetrates the rear side of the processing box 1 and connects to the first synchronous pulley 17. An inlet is provided on the left side of the processing box 1, and an outlet is provided on the bottom left side of the processing box 1. The first discharge port 3 and the bottom right side of the processing box 1 are connected by a second discharge port 31 and a third discharge port 32. A conveyor 11 is fixedly installed inside the inlet of the processing box 1. The garbage is poured onto the conveyor belt of the conveyor 11, which drives the garbage to move to the right and fall onto the screen plate 23. During the fall of the garbage, a high-speed airflow is blown out by the first blower box 2 to blow the light materials in the garbage to the right and discharge them through the third discharge port 32. Then, when the garbage falls onto the screen plate 23, the vibrating screen plate 23 vibrates and screens the garbage. The small garbage that is screened off will fall into the first discharge port 3 for discharge, while the large garbage will move to the right with the vibration of the screen plate 23 and fall into the second discharge port 31 for discharge.During the descent of the large waste, a high-speed airflow is blown out by the second blower box 21, pushing the lightweight materials in the waste to the right and discharging them through the third discharge port 32. The first blower box 2 is located below the conveyor 11, and the screen plate 23 is located to the right of the first blower box 2. The second blower box 21 is located below the bottom right support plate 24 of the screen plate 23. The screen holes of the screen plate 23 correspond to the first discharge port 3, and the right side of the screen plate 23 corresponds to the second discharge port 31. The first blower box 2 and the second blower box 21 correspond to the third discharge port 32.

[0022] Working principle: The impeller inside the high-pressure blower 12 is driven by the motor 13 to rotate, which in turn drives the second synchronous pulley 18 to rotate. The second synchronous pulley 18 drives the first synchronous pulley 17 to rotate via the synchronous belt 19. The first synchronous pulley 17 drives the camshaft 22 to rotate, which in turn drives the screen plate 23 to move up and down with the assistance of the spring telescopic rod 25. When the impeller inside the high-pressure blower 12 rotates, it inputs high-speed airflow into the three-way pipe 14. The high-speed airflow then enters the first diverter pipe 15 and the second diverter pipe 16 through the three-way pipe 14, and then enters the first air box 2 and the second air box 21 through the first diverter pipe 15 and the second diverter pipe 16, respectively. Inside, the garbage is poured onto the conveyor belt of the conveyor 11. The conveyor 11 drives the garbage to move to the right and fall onto the screen plate 23. During the fall of the garbage, a high-speed airflow is blown out by the first blower box 2 to blow the light materials in the garbage to the right and discharge them through the third discharge port 32. Then, when the garbage falls onto the screen plate 23, the vibrating screen plate 23 vibrates and screens the garbage. The small garbage that is screened off will fall into the first discharge port 3 for discharge, while the large garbage will move to the right with the vibration of the screen plate 23 and fall into the second discharge port 31 for discharge. During the fall of the large garbage, a high-speed airflow is blown out by the second blower box 21 to blow the light materials in the garbage to the right and discharge them through the third discharge port 32.
