Detailed Implementation

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] The waste processing line of this invention is suitable for processing waste generated in markets, generally referring to farmers' markets. The waste processing line can be built adjacent to the market, shortening the transportation distance of market waste to the storage warehouse.

[0023] As described in the background section, market waste mainly consists of wet waste, such as vegetables, meat, and fish. Of course, recyclables and dry waste are also unavoidable, such as styrofoam boxes, seashells, and bottles. For example, a typical market generates approximately 200 tons of waste per day, with wet waste accounting for about 70% of the total and dry waste and other waste accounting for about 30%.

[0024] Reference Figure 1 As shown, a waste processing line according to an embodiment of the present invention includes a storage bin 100, a crushing device 200, a material grabbing device 300, a compression device 400, a first conveying device 510, and a second conveying device 520.

[0025] For a market with a waste volume of 200 tons / day, the storage silo 100 can be designed with a volume of approximately 500m³. 3 For example, the dimensions can be 11.6m*8.6m*5m, which can store garbage for about 2.5 days.

[0026] Storage bin 100 is used to store waste to be processed; crushing device 200 is used to crush the waste; the moving range of grabbing device 300 covers storage bin 100 and crushing device 200, and grabbing device 300 can transfer waste in storage bin 100 to crushing device 200.

[0027] It is important to understand that a certain capacity of waste needs to be stored to facilitate the grabbing device 300's grabbing of waste from the storage bin 100. By adjusting the movement frequency of the grabbing device 300 between the storage bin 100 and the crushing device 200, the feeding speed of the grabbing device 300 onto the crushing device 200 can be controlled. Preferably, maintaining a constant feeding speed of the grabbing device 300 onto the crushing device 200 is beneficial for maintaining stable crushing operation of the crushing device 200. Alternatively, the size of the waste after being crushed by the crushing device 200 can be no greater than 350mm.

[0028] The material handling device 300 can be a combination of a grab bucket and a gantry. The gantry can be located on top of the storage bin 100. The feed inlet of the crushing device 200 is adjacent to the storage bin 100. The grab bucket moves with the gantry, grabbing the waste from the storage bin 100 and then feeding it into the feed inlet of the crushing device 200. In some embodiments, the volume of the grab bucket can be designed to be 1 m³. 3 .

[0029] The compression device 400 is used to compress the crushed waste. The compression device 400 has a solid discharge port and a liquid discharge port. The first conveying device 510 connects the crushing device 200 and the compression device 400. One end of the second conveying device 520 is connected to the solid discharge port.

[0030] The first conveying device 510 transfers the crushed waste from the crushing device 200 into the compression device 400 to press the small pieces of waste. The crushed waste is easier to enter the material chamber of the compression device 400 and is also easier to compress, which can improve the compression efficiency.

[0031] Preferably, the compression device 400 can be a vertical compression device, which has a high compression density for waste. It should be understood that vertical compression devices are relatively mature devices, so they will not be described in further detail here.

[0032] After the compression device 400 compresses the waste, the resulting slag is discharged from the solid discharge port, and the wastewater generated during compression is discharged from the liquid discharge port. The second conveying device 520 is used to transport the slag to a transfer vehicle for subsequent waste processing. In some embodiments, the compression density of the waste by the compression device 400 is greater than or equal to 0.95 tons / m³. 3 The preferred maximum compression force is greater than 120 tons, and the compression ratio is greater than 2.5:1.

[0033] Understandably, it also includes a wastewater treatment device 600 and a third conveying device 530, which connects the wastewater treatment device 600 and the liquid discharge port.

[0034] Furthermore, the wastewater generated by the compression device 400 during the pressing of waste can be treated. The third conveying device 530 can be a pipeline equipped with a pump to transport the wastewater to the wastewater treatment device 600. Maintaining a sealed environment during transport can reduce odor generation. It should be understood that market waste is predominantly organic, and the wastewater has a high organic content, so microbial treatment can be used to treat the wastewater. It should also be understood that the wastewater treatment device 600 is a relatively mature technology, so it will not be described in further detail here.

[0035] It is understood that the device also includes a sorting device 700, which is connected to the crushing device 200. The sorting device 700 has a coarse material outlet and a fine material outlet. One end of the first conveying device 510 is connected to the fine material outlet, and the other end of the first conveying device 510 is connected to the compression device 400.

[0036] To ensure the compression efficiency of the compression device 400, a sorting device 700 can be added to sort the waste crushed by the crushing device 200, controlling the size of the waste entering the compression device 400. Specifically, after sorting by the sorting device 700, smaller pieces of waste exit the fine material outlet and are then fed into the compression device 400 via the first conveying device 510.

[0037] In some embodiments, the sorting device 700 is adjusted to sort waste with a size not greater than 100 mm, while waste larger than 100 mm is discharged through the coarse material outlet.

[0038] It is understood that the sorting device 700 includes a roller 710 and a drive assembly. The roller 710 is arranged horizontally, and the drive assembly is connected to the roller 710 to drive the roller 710 to rotate. One end of the roller 710 is the feed end, and the other end of the roller 710 is the coarse material outlet 711. The side wall of the roller 710 is provided with multiple mesh holes, and the fine material outlet 712 is located at the lower part of the roller 710.

[0039] The mesh size of the roller 710 can be set to 100mm*100mm, which enables waste sorting and discharges waste with a size not greater than 100mm at the fine material outlet.

[0040] like Figure 2 The structure shown can also include a receiving hopper at the bottom of the drum 710, which can receive fine materials. The lowest point of the receiving hopper is the fine material outlet 712.

[0041] Understandably, it also includes a fourth conveying device 540, one end of which is connected to the coarse material outlet, and the other end of which is connected to the second conveying device 520.

[0042] In some embodiments, waste exceeding 100mm in size, i.e., waste exceeding the screening size of the sorting device 700, is discharged from the coarse material outlet without being pressed by the compression device 400 and is then conveyed by the fourth conveying device 540 to the second conveying device 520. It should be understood that the second conveying device 520 is used to convey the slag produced by the compression device 400, which can be mixed with the unpressed large-sized waste and finally transported by a transport vehicle.

[0043] It is understandable that the first conveying device 510, the second conveying device 520 and the fourth conveying device 540 are all belt conveyors.

[0044] Belt conveyors can use either trough or flat belts. Trough belts are preferred as they allow for better contact with waste during transmission, improving conveying efficiency.

[0045] It is understood that the compression device 400 includes a first compression mechanism and a second compression mechanism, which are independent of each other. The first conveying device 510 includes a first conveying section and a second conveying section. One end of the first conveying section is connected to the crushing device 200, and the other end of the first conveying section is connected to the second conveying section. One end of the second conveying section is connected to the first compression mechanism, and the other end of the second conveying section is connected to the second compression mechanism. The second conveying section can convey in both forward and reverse directions.

[0046] The crushed waste from the crushing device 200 is conveyed from the first conveying section to the second conveying section. Controlling the forward or reverse conveying of the second conveying section allows the crushed waste to be transported towards either the first or second compression mechanism. For example, in some embodiments, when the second conveying section conveys in the forward direction, it can transport the crushed waste to the first compression mechanism; when the second conveying section conveys in the reverse direction, it can transport the crushed waste to the second compression mechanism. It should be understood that when the first compression mechanism has been fed a sufficient amount of waste, it is activated to compress the waste. At this point, it is impossible to continue transporting waste towards the first compression mechanism, and the second conveying section switches from forward to reverse conveying to continue transporting waste to the second compression mechanism for further compression. The first and second compression mechanisms alternately perform compression operations, enabling continuous operation and improving work efficiency.

[0047] Understandably, storage compartment 100 includes multiple placement areas, each used to store different types of waste.

[0048] Since market waste is not entirely wet waste, sorting the waste allows for better crushing and compression of wet waste. With multiple storage areas in the storage bin 100, dry waste can be stored in one area, wet waste and waste that is difficult to sort in another, and recyclable waste in yet another. Preferably, there are at least three storage areas.

[0049] Understandably, the storage compartment 100 has a closed chamber, with at least one placement area located within the chamber.

[0050] Wet waste is stored in a closed chamber to further reduce odor leakage.

[0051] Understandably, it also includes an exhaust deodorization device 800, which is connected to the chamber and can generate negative pressure on the chamber.

[0052] Even if the wet waste produces an odor in the chamber, the air carrying the odor can be drawn away and deodorized by the exhaust and deodorization device 800.

[0053] It's important to understand that the air extracted by the 800 deodorizing device can be treated with ozone, photocatalysis, catalysts, and negative ion clusters to remove odors and harmful substances. The 800 deodorizing device is a relatively mature technology and will not be elaborated upon here. It's also worth noting that liquid deodorizers can be sprayed into the chamber where wet waste is stored. These deodorizers, obtained from natural plant extracts, can be sprayed through atomizing nozzles placed within the chamber to purify the air and eliminate odors.

[0054] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
