Description

Technical Field

[0002] With the acceleration of the urbanization process, the urban population has been increasing continuously, resulting in a sharp growth in the generation of urban garbage. Since a large amount of recyclable resources are contained in domestic waste, hierarchical treatment is required when treating domestic waste, so that recyclable resources are not easily wasted. And due to the limited urban land resources, it is difficult to select sites for landfills, and the landfill method causes great pressure on the environment. Treating all garbage by landfill not only leads to the waste of recyclable resources, but also increases the pressure on landfills and the environment. Therefore, hierarchical treatment of domestic waste has become one of the necessary processes for domestic waste treatment.

When treating domestic waste hierarchically, it is necessary to treat domestic waste device by device, which not only reduces the treatment efficiency of domestic waste, but also increases the energy consumption and the cost of hierarchical treatment of domestic waste due to the use of multiple devices. In addition, the placement of multiple domestic waste hierarchical treatment devices also increases the occupied space area, resulting in the waste of space resources. Summary of the Invention

Detailed implementation manners

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] Please refer to Figures 1-9As shown, a grading treatment device for domestic waste recycling includes a box body 1; one side of the inner wall of the box body 1 is fixedly connected with a connecting column 2; one end of the outer wall of the connecting column 2 is fixedly connected with a circular plate 3; one end of the outer wall of the circular plate 3 is hermetically and rotatably connected with a screening shell 4; one end of the top of the outer wall of the circular plate 3 is fixedly connected with a feeding shell 5, and the feeding shell 5 is communicated with the circular plate 3; one end of the bottom of the outer wall of the circular plate 3 is fixedly connected with a discharging shell 6, and the discharging shell 6 is communicated with the circular plate 3, and a valve is arranged in the discharging shell 6; one end of the outer wall of the discharging shell 6 penetrates through the box body 1; one side of the inner wall of the box body 1 is fixedly connected with a motor 7; the output end of the motor 7 is provided with a rotating shaft 8; one end of the outer wall of the circular plate 3 is provided with a stirring mechanism through a rotating rod 9; one side of the inner wall of the box body 1 is provided with a wind selection structure through a first rotating rod 10; one end of the outer wall of the rotating shaft 8 is fixedly connected with a first gear 11; the outer side wall of the screening shell 4 is fixedly connected with an annular rack 12, and the first gear 11 meshes with the annular rack 12. By putting domestic waste into the screening shell 4 from the feeding shell 5, at this time, the motor 7 drives the rotating shaft 8 to rotate, so that the rotating shaft 8 drives the annular rack 12 and the screening shell 4 to rotate through the first gear 11, so as to screen the domestic waste, preliminarily grade the domestic waste according to the particle size of the waste, and make the screening efficiency better through the stirring mechanism, and perform secondary classification on the domestic waste through the wind selection structure, so that the device completes the multi-stage and graded recycling treatment of domestic waste through a single motor 7, thereby not only improving the treatment efficiency of domestic waste, but also reducing the energy consumption and the occupied space area.

[0033] The stirring mechanism includes a first chain 13; one end of the outer wall of the rotating rod 9 is rotatably connected to one end of the outer wall of the circular plate 3, and one end of the outer wall of the rotating rod 9 penetrates through the screening shell 4; a group of stirring rods 14 are arranged on the outer side wall of one end of the rotating rod 9 located inside the screening shell 4; first sprockets 15 are fixedly connected to the outer wall of one end of the rotating rod 9 and the outer side wall of the rotating shaft 8, and a pair of first sprockets 15 are connected by a first chain 13. When the rotating shaft 8 rotates, the rotating shaft 8 drives the rotating rod 9 to rotate through the first sprocket 15 and the first chain 13, so that the rotating rod 9 drives a group of stirring rods 14 to rotate, accelerating the screening efficiency of domestic waste, and because the rotating directions of the screening shell 4 and the rotating rod 9 are opposite, when the stirring rods 14 stir the domestic waste, they will not be in a relatively static state.

[0034] One end of the outer wall of the circular plate 3 is fixedly connected to the second bevel gear 27 through the first round bar, and the second bevel gear 27 is sleeved on the outer wall of the rotating rod 9; one end of the outer wall of a group of stirring rods 14 is rotatably connected to the outer wall of the rotating rod 9; a third bevel gear 28 is fixedly connected to the outer wall of each of the group of stirring rods 14, and each of the group of third bevel gears 28 meshes with the second bevel gear 27. When the rotating rod 9 drives the stirring rod 14 to rotate, the third bevel gear 28 on the stirring rod 14 rotates accordingly. Since the third bevel gear 28 and the second bevel gear 27 mesh with each other, and the second bevel gear 27 remains in a fixed and precise state, the third bevel gear 28 rotates on its own through the second bevel gear 27, causing the third bevel gear 28 to drive the stirring rod 14 to rotate on its own, thereby enhancing the stirring efficiency and effect of the stirring rod 14, and thus making the screening efficiency of domestic waste better.

[0035] The air separation structure includes the first fan blade 16; one end of the outer wall of the first rotating rod 10 is rotatably connected to one side of the inner wall of the box body 1; second sprockets 17 are fixedly connected to the outer walls of the first rotating rod 10 and the rotating shaft 8, and a pair of second sprockets 17 are connected by a second chain 18; one end of the outer wall of each of the group of first fan blades 16 is fixedly connected to the outer wall of the first rotating rod 10; the first fan blade 16 is located below the screening shell 4; a square through groove 19 is formed on one side of the outer wall of the box body 1; a light box 20 and a heavy box 21 are arranged on the inner side wall of the square through groove 19; a filter plate 22 is fixedly connected to the inner side wall of the heavy box 21. When the small garbage is screened and dropped from the screening shell 4, the rotation of the rotating shaft 8 drives the first rotating rod 10 to rotate through the second sprocket 17 and the second chain 18, causing the first rotating rod 10 to drive the first fan blade 16 to rotate, and the first fan blade 16 generates wind power. As a result, the light garbage in the small garbage is blown under the action of the wind power, while the heavy garbage continues to drop regardless of the influence of the wind power, so that the light garbage drops into the light box 20, and the heavy garbage drops into the heavy box 21, enabling the secondary classification treatment of domestic waste. Moreover, through the filter plate 22 in the heavy box 21, the heavy garbage in the heavy box 21 is separated into dry and wet parts.

[0036] One side of the outer wall of the box body 1 is rotatably connected with a fifth rotating rod 32; a group of flexible rods 33 are fixedly connected to the outer wall of the fifth rotating rod 32; one end of the outer wall of the flexible rod 33 is fixedly connected with a vibrating ball 34; a group of vibrating rods are all matched with the screening shell 4; fifth sprockets 35 are fixedly connected to the outer walls of the fifth rotating rod 32 and the rotating shaft 8, and a pair of fifth sprockets 35 are connected by a fifth chain 36. When the rotating shaft 8 rotates, the rotation of the rotating shaft 8 drives the fifth rotating rod 32 to rotate through the fifth sprocket 35 and the fifth chain 36, so that the fifth rotating rod 32 drives the flexible rod 33 and the vibrating ball 34 to rotate, and the vibrating ball 34 impacts the screening shell 4 during rotation, causing the screening shell 4 to vibrate. And because the screening shell 4 is in a self-rotating state, the impact of the vibrating ball 34 is not at the same position each time, so that the screening shell 4 can be evenly subjected to the vibration force, and the vibration force can be evenly transmitted to the domestic waste, so that the domestic waste is shaken loose under the vibration, and the domestic waste is not easily adhered together, thereby making the screening effect of the domestic waste better.

[0037] One end of the rotating rod 9 located inside the screening shell 4 is rotatably connected with a group of auxiliary rods 29 on the outer wall, and a group of auxiliary rods 29 are respectively matched with a group of stirring rods 14; fourth sprockets 30 are fixedly connected to the outer walls of a group of auxiliary rods 29 and the stirring rods 14, and two groups of fourth sprockets 30 are connected by a group of fourth chains 31. When the stirring rod 14 rotates self-rotatingly, the stirring rod 14 drives the auxiliary rod 29 to rotate through the fourth sprocket 30 and the fourth chain 31, so that a group of auxiliary rods 29 and a group of stirring rods 14 both rotate self-rotatingly, and thus cooperate with each other to further improve the screening efficiency and screening effect of the domestic waste.

[0038] One side of the inner wall of the box body 1 is rotatably connected with a circular rod 38 through a connecting plate 37; an eighth bevel gear 39 is fixedly connected to the outer wall of the circular rod 38; a group of anti-blocking plates 40 are fixedly connected to the outer wall of the circular rod 38, and the anti-blocking plate 40 is matched with the heavy material box 21; one side of the inner wall of the box body 1 is rotatably connected with a ninth rotating rod 41; ninth sprockets 42 are fixedly connected to the outer walls of the ninth rotating rod 41 and the first rotating rod 10, and a pair of ninth sprockets 42 are connected by a ninth chain 43; a ninth bevel gear 44 is fixedly connected to one end of the outer wall of the ninth rotating rod 41, and the ninth bevel gear 44 meshes with the eighth bevel gear 39. When the first rotating rod 10 rotates, the first rotating rod 10 drives the ninth rotating rod 41 to rotate through the ninth sprocket 42 and the ninth chain 43, so that the ninth rotating rod 41 drives the ninth bevel gear 44 to rotate. Because the ninth bevel gear 44 meshes with the eighth bevel gear 39, the ninth bevel gear 44 drives the circular rod 38 to rotate through the eighth bevel gear 39, so that the circular rod 38 drives the anti-blocking plate 40 to rotate, and the anti-blocking plate 40 rotates in the heavy material box 21, thereby preventing the domestic waste from blocking the filter plate 22, and thus ensuring the wet-dry separation effect and efficiency of the domestic waste in the heavy material box 21.

[0039] On one side of the inner wall of the box body 1, a second rotating rod 23 is rotatably connected; a group of second fan blades 24 are fixedly connected to the outer side wall of the second rotating rod 23; third sprockets 25 are fixedly connected to the outer side walls of the second rotating rod 23 and the first rotating rod 10, and a pair of third sprockets 25 are connected by a third chain 26; the second fan blades 24 match the first fan blades 16. When the first rotating rod 10 rotates, the first rotating rod 10 drives the second rotating rod 23 to rotate through the third sprockets 25 and the third chain 26, so that the second rotating rod 23 drives a group of second fan blades 24 to rotate, and a group of second fan blades 24 cooperate with the first fan blades 16 to blow air, thereby covering the inside of the overall box body 1, thereby reducing the probability of the occurrence of wind dead angles and making the air separation and classification accuracy of the device higher.

[0040] The circular rod 38 includes a fixed circular shell 381 and a moving rod 382; the outer side wall of the moving rod 382 is slidably connected to the inner side wall of the fixed circular shell 381; the inner side wall of the eighth bevel gear 39 is fixedly connected to the outer side wall of the fixed circular shell 381; a lifting plate 45 is rotatably connected to the outer side wall of the moving rod 382; one side of the outer wall of the box body 1 is threadedly connected with a threaded rod 46 through a square plate, and the bottom end of the outer wall of the threaded rod 46 is rotatably connected to the top end of the outer wall of the lifting plate 45. Since the circular rod 38 includes a fixed circular shell 381 and a moving rod 382, when the threaded rod 46 is rotated, because the threaded rod 46 is threadedly connected with the square plate, the rotation of the threaded rod 46 causes the threaded rod 46 to move up and down, so that the threaded rod 46 drives the lifting plate 45 to move up and down, and the lifting plate 45 drives the moving rod 382 and the anti-blocking plate 40 to move up and down. When the heavy box 21 is placed in the box body 1, the anti-blocking plate 40 is first lifted. When the placement of the heavy box 21 is completed, the anti-blocking plate 40 is then lowered, so that the anti-blocking plate 40 moves to a suitable position to stir the domestic waste in the heavy box 21, thereby making the device more flexible and convenient.

[0041] Embodiment 2:

[0042] Please refer to Figure 3 and Figure 9As shown, the anti-blocking plate 40 is an electromagnetic plate; the top of the outer wall of the connecting plate 37 is arc-shaped; a clamping device is provided on the outer side wall of the threaded rod 46; corrosion-resistant layers are provided on the inner side walls of the box body 1, the heavy-duty box 21 and the light-duty box 20. Since the anti-blocking plate 40 is an electromagnetic plate, when the anti-blocking plate 40 stirs in the heavy waste, the anti-blocking plate 40 will adsorb magnetic metal substances. When the anti-blocking plate 40 moves upward, the heavy-duty box 21 is taken out. At this time, the power of the anti-blocking plate 40 is disconnected, so that the magnetism of the anti-blocking plate 40 disappears. At this time, the magnetic metal substances adsorbed by the anti-blocking plate 40 fall off. At this time, the staff collects the magnetic metal substances, so that the device not only classifies domestic waste according to the particle size of the waste, but also classifies small waste into light waste and heavy waste, and separately collects and recovers the magnetic metal substances in the heavy waste, so that the device completes the multi-stage and classified recycling treatment of domestic waste through a single motor 7, thereby not only improving the treatment efficiency of domestic waste, but also reducing energy consumption and reducing the occupied space area. And because the top of the outer wall of the connecting plate 37 is arc-shaped, when the domestic waste is classified, the domestic waste is not easy to stay on the connecting plate 37. And because a clamping device is provided on the outer side wall of the threaded rod 46, and the clamping device is a prior art, the threaded rod 46 is not easy to rotate randomly. And because corrosion-resistant layers are provided on the inner side walls of the box body 1, the heavy-duty box 21 and the light-duty box 20, the service life of the device is increased.

[0043] When the present invention is in use, domestic waste is put into the screening shell 4 from the feeding shell 5. At this time, the motor 7 drives the rotating shaft 8 to rotate, so that the rotating shaft 8 drives the annular rack 12 and the screening shell 4 to rotate through the first gear 11, so as to screen the domestic waste and preliminarily classify the domestic waste according to the particle size of the waste.

[0044] When the rotating shaft 8 rotates, the rotating shaft 8 drives the rotating rod 9 to rotate through the first sprocket 15 and the first chain 13, so that the rotating rod 9 drives a group of stirring rods 14 to rotate, accelerating the screening efficiency of domestic waste. And because the screening shell 4 and the rotating rod 9 rotate in opposite directions, when the stirring rods 14 stir the domestic waste, they will not be in a relatively static state.

[0045] When the rotating rod 9 drives the stirring rods 14 to rotate, the third bevel gear 28 on the stirring rods 14 rotates accordingly. Since the third bevel gear 28 meshes with the second bevel gear 27 and the second bevel gear 27 remains in a fixed and precise state, the third bevel gear 28 rotates by itself through the second bevel gear 27, so that the third bevel gear 28 drives the stirring rods 14 to rotate by themselves, thereby enhancing the stirring efficiency and stirring effect of the stirring rods 14, and thus making the screening efficiency of domestic waste better.

[0046] When the stirring rod 14 rotates on its own axis, the stirring rod 14 drives the auxiliary rod 29 to rotate through the fourth sprocket 30 and the fourth chain 31, causing a group of auxiliary rods 29 and a group of stirring rods 14 to rotate on their own axes, thus cooperating with each other to further improve the screening efficiency and screening effect of domestic waste.

[0047] When the rotating shaft 8 rotates, the rotation of the rotating shaft 8 drives the fifth rotating rod 32 to rotate through the fifth sprocket 35 and the fifth chain 36, causing the fifth rotating rod 32 to drive the flexible rod 33 and the vibrating ball 34 to rotate. When the vibrating ball 34 rotates, it impacts the screening shell 4, causing the screening shell 4 to vibrate. Since the screening shell 4 is in a state of self-rotation, each impact of the vibrating ball 34 is not at the same position, enabling the screening shell 4 to receive the vibration force evenly, allowing the vibration force to be evenly transmitted to the domestic waste, causing the domestic waste to be shaken loose under vibration and preventing the domestic waste from sticking together easily, thereby making the screening effect of the domestic waste better.

[0048] When the screening of domestic waste is completed, by opening the valve at the discharge shell 6, the large garbage and small garbage in the screening shell 4 are screened and classified, so that the domestic waste can be classified more precisely for subsequent processing.

[0049] When the small garbage is screened and falls from the screening shell 4, the rotation of the rotating shaft 8 drives the first rotating rod 10 to rotate through the second sprocket 17 and the second chain 18, causing the first rotating rod 10 to drive the first fan blade 16 to rotate, generating wind force. As a result, the light garbage in the small garbage is blown under the action of the wind force, while the heavy garbage continues to fall regardless of the wind force. The light garbage falls into the light garbage box 20, and the heavy garbage falls into the heavy garbage box 21, enabling the secondary classification of domestic waste. And through the filter plate 22 in the heavy garbage box 21, the heavy garbage in the heavy garbage box 21 is separated into dry and wet components.

[0050] When the first rotating rod 10 rotates, the first rotating rod 10 drives the second rotating rod 23 to rotate through the third sprocket 25 and the third chain 26, causing the second rotating rod 23 to drive a group of second fan blades 24 to rotate. The group of second fan blades 24 cooperate with the first fan blade 16 to blow air, thus covering the entire interior of the box body 1, reducing the probability of the appearance of wind force dead angles, and making the wind selection classification accuracy of this device higher.

[0051] When the first rotating rod 10 rotates, the first rotating rod 10 drives the ninth rotating rod 41 to rotate through the ninth sprocket wheel 42 and the ninth chain 43, causing the ninth rotating rod 41 to drive the ninth bevel gear 44 to rotate. Since the ninth bevel gear 44 meshes with the eighth bevel gear 39, the ninth bevel gear 44 drives the circular rod 38 to rotate through the eighth bevel gear 39, causing the circular rod 38 to drive the anti-blocking plate 40 to rotate, and the anti-blocking plate 40 rotates within the heavy material box 21, thereby preventing domestic waste from blocking the filter plate 22, thus ensuring the wet-dry separation effect and efficiency of the domestic waste in the heavy material box 21.

[0052] Since the circular rod 38 includes a fixed circular shell 381 and a moving rod 382, when the threaded rotating rod 46 rotates, since the threaded rotating rod 46 is threadedly connected to the square plate, the rotation of the threaded rotating rod 46 causes the threaded rotating rod 46 to move up and down, causing the threaded rotating rod 46 to drive the lifting plate 45 to move up and down, causing the lifting plate 45 to drive the moving rod 382 and the anti-blocking plate 40 to move up and down. When the heavy material box 21 is placed in the box body 1, the anti-blocking plate 40 is first lifted. When the heavy material box 21 is placed, the anti-blocking plate 40 is then lowered, causing the anti-blocking plate 40 to move to a suitable position to stir the domestic waste in the heavy material box 21, thereby making the device more flexible and convenient.

[0053] Since the anti-blocking plate 40 is an electromagnetic plate, when the anti-blocking plate 40 stirs in the heavy waste, the anti-blocking plate 40 will adsorb magnetic metal substances. When the anti-blocking plate 40 is lifted, the heavy material box 21 is taken out. At this time, the power supply of the anti-blocking plate 40 is disconnected, causing the magnetism of the anti-blocking plate 40 to disappear. At this time, the magnetic metal substances adsorbed by the anti-blocking plate 40 fall off. At this time, the staff collects the magnetic metal substances, making the device not only classify domestic waste according to the particle size of the waste, but also classify small waste into light waste and heavy waste, and separately collect and recycle the magnetic metal substances in the heavy waste. The device completes the multi-stage and classified recycling treatment of domestic waste through a single motor 7, thereby not only improving the treatment efficiency of domestic waste, but also reducing energy consumption, and reducing the occupied space area. And since the top end of the outer wall of the connecting plate 37 is arc-shaped, when classifying domestic waste, the domestic waste is not likely to stay on the connecting plate 37. And since a clamping device is provided on the outer side wall of the threaded rotating rod 46 and the clamping device is a prior art, the threaded rotating rod 46 is not likely to rotate randomly. And since the inner side walls of the box body 1, the heavy material box 21 and the light material box 20 are all provided with corrosion-resistant layers, the service life of the device is increased.
