[0001] This application relates to the technical field of organic waste treatment, and particularly to a double-rotor sorting device for organic waste treatment. Background Art

[0002] With the implementation and promotion of domestic waste classification, more and more cities are carrying out waste classification collection in accordance with the national standard method, and the demand for proper treatment of classified catering and kitchen waste is gradually increasing. Among them, the anaerobic digestion process for treating catering and kitchen waste: with the energy utilization attribute of anaerobic biogas utilization, the resource attribute of the potential for fertilizer development of biogas residue, and comprehensive benefits such as pollution reduction and carbon reduction, has gradually become the main treatment process for classified catering and kitchen waste.

[0003] After the implementation of waste classification is launched, compared with the wet waste after classification of mixed waste or traditional dry-wet waste dichotomy, the components such as plastic bags, wet wipes, glass, porcelain chips, metals, etc. in classified catering and kitchen waste have been greatly reduced. Therefore, there is no need to adopt pretreatment processes with complex processes and numerous equipment, and pretreatment equipment with high cost and complicated operation and maintenance, such as special crushers, multi-stage bag-breaking drum screens, air separators, optical separators, and other process equipment. In some areas with good classification effects, catering and kitchen waste can be mixed for collaborative treatment.

[0004] Therefore, in view of the demand for collaborative treatment of catering and kitchen waste and subsequent anaerobic digestion treatment after waste classification, a device with a large processing capacity, strong material adaptability, diverse functions, simple structure, excellent performance, and economical operation that can effectively remove impurities such as plastic bags, wet wipes, glass, porcelain chips, metals, etc. is needed. Currently, the common crushing and sorting devices on the market are all single-axis designs, with limited processing capacity and poor crushing and sorting effects. Summary of the Invention

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope protected by the present application.

[0021] In the description of the present application, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0022] Please refer to Figures 1 to 5, embodiments of the present application provide a dual-rotor sorting device for organic waste treatment, including a crushing and sorting bin 1, a primary crushing mechanism 2, a secondary crushing mechanism 3, a filtering mechanism 4, and a receiving bin. Among them, the crushing and sorting bin 1 is provided with a feeding port 111, a discharging port 13, a slag discharging port 121, a primary crushing chamber 14, and a secondary crushing chamber 15. The primary crushing chamber 14 and the secondary crushing chamber 15 are connected. The feeding port 111 is arranged above the primary crushing chamber 14, the discharging port 13 is arranged below the primary crushing chamber 14 and the secondary crushing chamber 15, and the slag discharging port 121 is arranged above the secondary crushing chamber 15. The primary crushing mechanism 2 is arranged on one side of the crushing and sorting bin 1, and the crushing end of the primary crushing mechanism 2 extends into the primary crushing chamber 14. The secondary crushing mechanism 3 is arranged on one side of the crushing and sorting bin 1, and the crushing end of the secondary crushing mechanism 3 extends into the secondary crushing chamber 15. The filtering mechanism 4 is arranged in the crushing and sorting bin 1 and is located between the discharging port 13 and the primary crushing chamber 14. The receiving bin is arranged below the discharging port 13 and is communicated with the discharging port 13.

[0023] The technical solution provided by the present application sets two crushing mechanisms in the crushing and sorting bin 1, namely the primary crushing mechanism 2 and the secondary crushing mechanism 3, and uses the two crushing mechanisms to perform hierarchical treatment on organic waste. Compared with the traditional single-shaft hammer mill roller, the crushing effect on organic waste is better, finer slurry can be obtained, and the crushing pressure on a single crushing mechanism is smaller, which is beneficial to extending the service life of a single crushing mechanism. In addition, while the secondary crushing mechanism 3 performs secondary crushing on the waste, it can also discharge the uncrushable waste through the slag discharging port 121, and the slurry after the waste is crushed will flow into the receiving bin after being filtered by the filtering mechanism 4, completing the sorting and pulping of organic waste.

[0024] In some embodiments, please refer to Figure 4 and Figure 5 , the primary crushing mechanism 2 includes a first motor 21, a first rotating shaft 22, and a plurality of first hammer milling components 23. The first motor 21 is arranged on one side of the crushing and sorting bin 1. The first rotating shaft 22 is connected to the output end of the first motor 21 and extends into the primary crushing chamber 14. The plurality of first hammer milling components 23 are rigidly sleeved on the first rotating shaft 22 and are located in the primary crushing chamber 14. The plurality of first hammer milling components 23 are arranged at intervals along the axial direction of the first rotating shaft 22. By driving the first rotating shaft 22 to rotate with the first motor 21, the first rotating shaft 22 drives the first hammer milling components 23 to rotate, and impacts and collides with the organic waste entering the crushing and sorting bin 1, so that the organic waste is subjected to primary crushing. It should also be noted that the connection relationship between the first hammer milling component 23 and the first rotating shaft 22 is a rigid sleeve connection. Compared with the traditional hammer milling rod freely hanging on the surface of the rotating shaft, the connection between the first hammer milling component 23 and the first rotating shaft 22 is more stable and has higher strength, and can adapt to the crushing of organic waste with greater hardness.

[0025] Furthermore, the first hammer grinding assembly 23 includes a first rotating disk 231 and a plurality of first hammer heads 232. The first rotating disk 231 is rigidly sleeved on the first rotating shaft 22, and the plurality of first hammer heads 232 are rigidly connected at intervals along the circumferential direction of the first rotating disk 231. By rigidly sleeving the first rotating disk 231 on the first rotating shaft 22 and rigidly connecting the first hammer heads 232 to the first rotating disk 231, the double rigid connection enables the rotation of the first rotating shaft 22 to synchronously drive the rotation of the plurality of first hammer heads 232 and the strength is higher than that of the hammer mounting method with free hanging. When the first rotating shaft 22 rotates, the plurality of first hammer heads 232 rotate synchronously, which will repeatedly impact the organic waste in the crushing and sorting bin 1, so that the organic waste is crushed into smaller pieces of waste. Part of the waste will fall into the receiving bin under the conditions met by the filtering mechanism 4, completing the sorting and pulping of part of the organic waste.

[0026] Still further, the plurality of first hammer heads 232 include a plurality of first sub-hammer heads and a plurality of second sub-hammer heads. A plurality of tearing nails are provided on both sides of the plurality of first sub-hammer heads and the plurality of second sub-hammer heads in the axial direction. The tearing nails are in the shape of a triangular pyramid, so that in addition to the cutting at the tip, the tearing nails can also have multiple cutting edges. When the organic waste is between the two first hammer grinding assemblies 23, the first hammer heads 232 cannot form a relatively effective impact on this part of the organic waste. However, as the first hammer heads 232 rotate, the plurality of tearing nails will form a cutting effect on the organic waste located between the adjacent two first hammer grinding assemblies 23. For example, plastic bags, packaging bags, etc. will be cut by the tearing nails, improving the crushing effect of the organic waste in the primary crushing process. The plurality of first sub-hammer heads and the plurality of second sub-hammer heads are alternately arranged at intervals in the axial direction.

[0027] In some embodiments, the first sub-hammer head has a uniform thickness in the axial direction, and the second sub-hammer head has a thickness that gradually decreases from the center towards the edge in the axial direction. By utilizing the characteristic of the uniform thickness of the first sub-hammer head, the first sub-hammer head has a relatively wide area on the impact surface for impacting the organic waste, mainly playing an impact role on the organic waste. Also, by utilizing the characteristic that the thickness of the second sub-hammer head gradually decreases from the center towards the edge, the edge of the second sub-hammer head is sharper and the pressure when impacting the organic waste is greater, mainly playing a cutting role on the organic waste.

[0028] In some embodiments, please refer to Figure 3 and Figure 4, the secondary crushing mechanism 3 includes a second motor 31, a second rotating shaft 32, and a plurality of second hammer-milling components 33. The second motor 31 is arranged on one side of the crushing and sorting bin 1. The second rotating shaft 32 is connected to the output end of the second motor 31 and extends into the secondary crushing chamber 15. A plurality of second hammer-milling components 33 are rigidly sleeved on the second rotating shaft 32 and are located in the secondary crushing chamber 15. The plurality of second hammer-milling components 33 are arranged at intervals along the axial direction of the second rotating shaft 32. The second hammer-milling component 33 has the same structure as the first hammer-milling component 23, and the structure of the second hammer-milling component 33 will not be described in detail here.

[0029] Furthermore, the primary crushing mechanism 2 and the secondary crushing mechanism 3 are arranged horizontally at intervals. The plurality of first hammer-milling components 23 and the plurality of second hammer-milling components 33 are arranged in a staggered manner, so that in the axial direction, the gap between two adjacent first hammer-milling components 23 can be filled by the second hammer-milling component 33, and the gap between two adjacent second hammer-milling components 33 can be filled by the first hammer-milling component 23, enabling the primary crushing mechanism 2 and the secondary crushing mechanism to cooperate complementarily and improving the crushing effect of organic waste.

[0030] In some embodiments, a crushing plate 6 is provided in the crushing and sorting bin 1. The crushing plate 6 is located above the first hammer-milling component 23 and the second hammer-milling component 33 and is located between the feed inlet 111 and the slag outlet 121. The crushing plate 6 includes a plate body 61, a plurality of first blades 62, and a plurality of second blades 63. The plurality of first blades 62 and the plurality of second blades 63 are both arranged on the side of the plate body 61 facing the discharge port 13. The plurality of first blades 62 are located above the first hammer-milling component 23, and the plurality of second blades 63 are located above the second hammer-milling component 33. By using the cooperation between the first blade 62 and the first hammer head 232 on the first hammer-milling component 23, the organic waste can be repeatedly impacted between the first blade 62 and the first hammer head 232 to improve the crushing effect, and a shearing effect can also be formed between the first blade 62 and the first hammer head 232 to further improve the crushing effect of the organic waste. Similarly, the second blade 63 cooperates with the second hammer head on the second hammer-milling component 33, so that the organic waste can be repeatedly impacted between the second blade 63 and the second hammer head to improve the crushing effect, and a shearing effect can also be formed between the second blade 63 and the second hammer head to further improve the crushing effect of the organic waste.

[0031] In some embodiments, please refer to Figure 5 , the filtering mechanism 4 includes two filtering components. One filtering component is arranged below the primary crushing mechanism 2, and the other filtering component is arranged below the secondary crushing mechanism 3. The primary crushing mechanism 2 and the secondary crushing mechanism 3 continuously crush the organic waste. When the volume of the organic waste is reduced to meet the filtering requirements of the filtering component, it can fall into the receiving bin through the filtering component to complete the collection of the slurry.

[0032] Further, the filtering component includes a plurality of filter meshes 41. The plurality of filter meshes 41 are arranged adjacent to each other, and the aperture range of the mesh openings of the filter meshes 41 is 6 mm to 30 mm to ensure that the volume of the organic waste flowing into the material receiving bin meets the requirements of the slurry. Moreover, the plurality of filter meshes 41 are of an independent screen structure to facilitate subsequent partial replacement and cleaning of the filter meshes 41.

[0033] In some embodiments, the double-rotor sorting device further includes a feed cylinder 9 and a slag discharge elbow 10. The feed cylinder 9 is connected to the feed port for feeding. The slag discharge elbow 10 is connected to the slag discharge port 121 and mainly receives the organic waste that has not been broken by the secondary crushing mechanism 3. This part of the organic waste will, under the rotational action of the secondary crushing structure, be subjected to a thrust force and its own inertia, move towards the slag discharge port 121, and then fall into the slag discharge elbow 10 to prevent excessive accumulation of unbreakable organic waste in the crushing and sorting bin 1.

[0034] Further, the double-rotor sorting device further includes an auxiliary slag discharge mechanism. The auxiliary slag discharge mechanism includes a third motor, a slag discharge rotating shaft, and a plurality of slag discharge blades. The plurality of slag discharge blades are arranged at intervals along the circumferential direction of the slag discharge rotating shaft. The two sides of each slag discharge blade are in clearance fit with the inner wall of the slag discharge elbow 10 so that the slag discharge blades can cover the inner diameter of the slag discharge elbow 10 as much as possible without affecting the movement of the slag discharge blades. One end of the slag discharge rotating shaft extends outside the slag discharge elbow 10 and is connected to the output end of the third motor so that the third motor can drive the slag discharge rotating shaft to rotate.

[0035] In some embodiments, the crushing and sorting bin 1 includes a sorting bottom bin 16, a first bin cover 11, and a second bin cover 12. The first bin cover 11 and the second bin cover 12 are both arranged above the sorting bottom bin 16 to cover the sorting bottom bin 16. The first bin cover 11 and the second bin cover 12 are arranged at intervals. The first bin cover 11 is provided with a feed port, and the second bin cover 12 is provided with a slag discharge port 121. The first bin cover 11 is hinged to one side of the sorting bottom bin 16 so that the first bin cover 11 can open or close a part of the inspection opening of the sorting bottom bin 16 by rotation. The second bin cover 12 is hinged to the other side of the sorting bottom bin 16 so that the second bin cover 12 can open or close another part of the inspection opening of the sorting bottom bin 16 by rotation. The slag discharge elbow 10 is also hinged to the second bin cover 12 so that the slag discharge elbow 10 can also rotate, avoiding the slag discharge elbow 10 blocking the inspection opening of the sorting bottom bin 16 after the bin cover is opened and affecting subsequent inspection and maintenance.

[0036] In some embodiments, please refer to Figure 2 and Figure 6, two first telescopic hydraulic rods 7 are provided on both sides of the sorting bottom bin 16 in the axial direction. In the axial direction, the two first telescopic hydraulic rods 7 on the same side are arranged at intervals. One end of one of the first telescopic hydraulic rods 7 on the same side is hinged to the sorting bottom bin 16, and the other end is hinged to one side of the second bin cover 12 close to the sorting bottom bin 16. One end of the other first telescopic hydraulic rod 7 is hinged to the sorting bottom bin 16, and the other end is hinged to one side of the first bin cover 11 close to the sorting bottom bin 16. Second telescopic hydraulic rods 8 are provided on both sides of the second bin cover 12 in the axial direction. One end of the second telescopic hydraulic rod 8 is hinged to a hinge seat, and this hinge seat is rigidly connected to the rigid connection at the hinge of the first hydraulic telescopic rod through a rigid connecting piece. The other end of the second telescopic hydraulic rod 8 is hinged to one side of the slag discharge elbow 10 close to the second bin cover 12. When the four first telescopic hydraulic rods 7 extend and the two second telescopic hydraulic rods 8 also extend, the feeding cylinder 9 and the first bin cover 11 will rotate and open a part of the inspection opening under the action of the first telescopic hydraulic rods 7 to expose the primary crushing mechanism 2; the slag discharge elbow 10 will, under the action of the second telescopic hydraulic rods 8, and the second bin cover 12 will, under the action of the first telescopic hydraulic rods 7, cooperate to rotate and open a part of the inspection opening to expose the secondary crushing mechanism 3, facilitating the inspection and maintenance of the primary crushing mechanism 2 and the secondary crushing mechanism 3.
