Description

Technical Field

[0001] This utility model relates to the field of waste separation technology, specifically to a waste separation device. Background Technology

[0002] Existing waste separation devices for separating organic and inorganic waste use screens to filter and separate waste of different sizes. The small particles that pass through the screen and enter the fine material zone are mostly organic waste such as kitchen waste and food, which can be fermented into biogas. The large particles that do not pass through the screen and remain in the coarse material zone are mostly inorganic waste such as stones and metals, which can be recycled as building materials. However, existing separation mechanisms have the problem of poor waste crushing effect, which leads to a large amount of organic waste remaining in the coarse material zone. This results in poor separation effect, low resource utilization rate, and serious waste of resources. Utility Model Content

[0024] See Figure 1-4 As shown in the figure, as an embodiment of the present invention, a waste separation device is provided, including a separation mechanism 1 with an open top and a screen 2 inclinedly arranged inside the separation mechanism 1. The screen 2 divides the separation mechanism 1 into a coarse material zone 11 and a fine material zone 12. The screen 2 is used to filter and separate the waste. A crushing mechanism is provided above the separation mechanism 1. The crushing mechanism is used to circulate and crush the waste in the coarse material zone 11 and transport it back to the coarse material zone 11. This makes the organic waste in the coarse material zone 11 more thoroughly and finely crushed, with a better crushing effect, so that it can pass smoothly through the screen 2 into the fine material zone 12, and be used by the subsequent fermentation mechanism 10 to ferment and produce biogas. Moreover, the proportion of inorganic waste in the coarse material zone 11 is higher, so it can be used as a higher quality and purer building material. That is, the separation effect is better, the resource utilization rate is higher, and the resources are better recycled.

[0025] In this embodiment, the screen 2 is connected to a driving component 3, specifically a motor, which drives the screen 2 to reciprocate and vibrate, thereby separating the waste through vibration and improving the filtration and separation effect.

[0026] In this embodiment, a sediment collection tank 8 is connected below the coarse material zone 11. A valve 9 is installed between the sediment collection tank 8 and the coarse material zone 11. The valve 9 is opened periodically to collect and process the sediment with a high proportion of inorganic matter and a hard texture at the bottom of the coarse material zone 11.

[0027] In this embodiment, the separation mechanism 1 is a cylindrical separation mechanism with an open top. The bottom of the screen 2 abuts against the middle area of ​​the inner bottom wall of the separation mechanism 1, and the top of the screen 2 abuts against the inner side wall of one side of the separation mechanism 1. That is, the coarse material area 11 corresponds to the upper left side of the screen 2, and the fine material area 12 corresponds to the lower right side of the screen 2. This arrangement makes the area of ​​the screen 2 larger, further improving the separation efficiency and effect.

[0028] In this embodiment, a fermentation mechanism 10 is connected to one side of the fine material zone 12, and the organic waste in the fine material zone 12 can overflow to the fermentation mechanism 10 for fermentation treatment.

[0029] In this embodiment, the diameter of the mesh opening of the screen 2 is in the range of 0.1 to 1 cm, specifically 0.5 cm, which can isolate most of the inorganic waste and ensure the separation effect.

[0030] In this embodiment, the crushing mechanism includes an inclined hook 42 conveying unit 4 and a mixing and crushing unit 5. The bottom end of the hook 42 conveying unit 4 extends into the inner top of the coarse material zone 11, and the top end of the hook 42 conveying unit 4 is connected to the feed inlet of the mixing and crushing unit 5. The discharge outlet of the mixing and crushing unit 5 is connected to the inner top of the coarse material zone 11. Specifically, the hook 42 conveying unit 4 includes a conveyor belt 41 and multiple hooks 42 arranged along the conveying direction on the surface of the conveyor belt 41. Material baffles 43 are formed on both sides of the conveyor belt 41 corresponding to the hooks 42, and the material baffles 43 can prevent waste from flowing out from both sides of the hooks 42. The mixing and crushing unit 5 includes a mixing drum 51 and a spiral mixing shaft 52 installed in the mixing drum 51. A funnel 6 is installed at the feed inlet of the mixing drum 51, and the funnel 6 is connected to the top end of the hook 42 conveying unit 4. The discharge outlet of the mixing drum 51 is connected to a return channel 7, and the lower end of the return channel 7 is connected to the inner top of the coarse material zone 11. The hook 42 of the conveying mechanism picks up the waste from the top of the coarse material zone 11 and transports it to the mixing and crushing unit 5 for cyclic crushing, ensuring the mixing and crushing effect of the waste. Then, it flows back to the coarse material zone 11 through the return channel 7.

[0031] In this embodiment, the inclination angle between the mixing and crushing unit 5 and the return channel 7 is in the range of 30 to 60 degrees, which makes the mixing and crushing effect of the waste better.
