Description

Technical Field

[0001] The utility model belongs to the technical field of waste sorting, and more specifically, particularly relates to a solid waste sorting device. Background Art

[0002] With the acceleration of industrialization and the advancement of urbanization, the output of solid waste has increased dramatically, causing serious pressure on the ecological environment. Countries have carried out classification, reduction, resource utilization and harmless treatment of waste. Early solid waste mainly relied on manual picking. With the development of science and technology, it now includes diameter screening, gravity sorting, magnetic sorting, etc. Among them, the gravity sorting sorting device uses wind separation to stratify and separate the waste. In the wind separation process, a large amount of waste, plastics, paper, etc. are mixed with heavy objects such as stones and soil. It takes a period of separation on the vibration belt to achieve wind separation and stratification, and the sorting efficiency is insufficient.

[0003] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a solid waste sorting device is provided to achieve a more practical purpose. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a solid waste sorting device to solve the problem that when there is too much waste, plastics, paper, etc. are mixed with heavy objects such as stones and soil, and it takes a period of time on a vibrating belt to separate them before they can be separated by wind and stratified, resulting in insufficient sorting efficiency.

[0005] The purpose and effect of the solid waste sorting device of the utility model are achieved by the following specific technical means:

[0006] A solid waste sorting device comprises a frame, wherein a sorting bin is arranged in the frame, a feed port is arranged obliquely on the top of the sorting bin, a first outlet and a second outlet are arranged at the front and rear of the bottom of the sorting bin respectively, a fan is arranged on the frame, the air outlet of the fan is connected with the front end of the sorting bin through a vertical air duct, a vibration plate is arranged obliquely in the sorting bin between the first outlet and the second outlet, the inclined surface of the vibration plate faces the vertical air duct, a buffer barrel corresponding to the position of the feed port is rotatably connected in the sorting bin, the buffer barrel abuts against the feed inclined surface at the bottom of the feed port, and the central axis of the buffer barrel is connected to the motor outside the sorting bin.

[0007] Furthermore, the sliding card at the bottom of the sorting bin is provided with a vibration grid, the vibration plate is arranged on the top of the vibration grid, the bottom of the vibration grid is connected to the frame through a plurality of springs, and a vibrator is arranged at the bottom of the vibration grid.

[0008] Furthermore, a flexible baffle is provided at the upturned end of the vibration plate, and the bottom of the flexible baffle rests on the second outlet end wall.

[0009] Furthermore, a plurality of grooves are provided on the surface of the buffer barrel.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] A large amount of solid waste can be piled up by setting the feed port tilted, and the solid waste will slide along the feed slope into the sorting bin, while the buffer barrel prevents the solid waste from falling into the sorting bin in a concentrated manner. The buffer barrel can slowly and evenly drive the waste accumulated on the feed slope into the sorting bin through rotation, avoiding a large amount of accumulated waste from falling directly into the sorting bin. A small amount of evenly distributed waste is blown by the wind from the vertical air duct, which is convenient for stratification. The light waste is blown to the second outlet, and the heavier waste flows out through the first outlet, thereby improving the efficiency of the fan in sorting waste.

[0023] A buffer barrel 8 corresponding to the position of the feed port 5 is rotatably connected in the sorting bin 2. The buffer barrel 8 abuts against the feed slope 51 at the bottom of the feed port 5. The buffer barrel 8 prevents solid waste from falling into the sorting bin 2 in a concentrated manner, and prevents a large amount of accumulated waste from directly falling into the sorting bin 2. The central axis of the buffer barrel 8 is connected to the motor 13 outside the sorting bin 2. The motor 13 drives the buffer barrel 8 to rotate, and can slowly and evenly drive the waste accumulated on the feed slope 51 into the sorting bin 2.

[0025] A vibrating plate 9 is obliquely arranged in the sorting bin 2 between the first outlet 6 and the second outlet 7, with the inclined surface of the vibrating plate 9 facing the vertical air duct 4. The waste brought out by the buffer barrel 8 falls onto the vibrating plate 9, and the heavy objects slide to the first outlet 6 along the inclined surface of the vibrating plate 9, while the wind blown out of the vertical air duct 4 blows the light objects to move upward along the inclined surface of the vibrating plate 9 until they fall out of the second outlet 7.
