Explanation of Main Component Symbols

[0040] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0041] Example 1:

[0042] Please refer to Figures 1 to 12. The multi-source organic waste co-processing system of Embodiment 1 of the present invention mainly consists of a frame 1, a coarse crusher 2, a mixer 3, a feeding screw conveyor 4, a fine crusher 5, a collection bin 6, and a discharger 7. The frame 1 is a three-dimensional frame structure constructed by overlapping components.

[0043] The collection bin 6 is connected and installed on the upper part of the frame 1, and the fine crusher 5 is located at the lower part of the collection bin 6 and connected and installed on the lower part of the frame 1. A frame 1 also extends and is connected to the coarse crusher 2, mixer 3, feeding screw conveyor 4, and unloader 7 on the side of the frame 1 to which the fine crusher 5 and the collection bin 6 are fixed. The coarse crusher 2, the mixer 3, and the feeding screw conveyor 4 are fixed and installed on the frame 1 on the side of the collection bin 6 from top to bottom; the feeding screw conveyor 4 is connected and installed between the mixer 3 and the fine crusher 5; the collection bin 6 is connected and installed at the output end of the fine crusher 5; the unloader 7 is connected below the collection bin 6. At this time, the collection bin 6 of the multi-source organic waste co-processing system is connected to the fine crusher 5 and the unloader 7 respectively; the coarse crusher 2, mixer 3, feeding screw conveyor 4, and fine crusher 5 are sequentially fixed and connected. A baffle plate is installed between the collection bin 6 and the fine crusher 5 on the side facing the fine crusher 5. This baffle plate prevents waste material from entering the fine crusher 5 when the collection bin 6 is unloaded by the discharger 7. The material passing through the discharger 7 can enter the fermentation treatment stage. The material in the multi-source organic waste fermentation treatment stage can also be fed through the feed inlet above the coarse crusher 2. The coarse crusher 2 will then further crush the fermented dry material, and then it will be processed sequentially through the mixer 3, the feeding screw conveyor 4, the fine crusher 5, the collection bin 6, and the discharger 7 before entering the re-fermentation treatment stage. The fine crusher 5 includes a motor 51 and a fine crushing roller structure 52, which are connected by a transmission structure such as a belt or gear. This invention achieves synergistic processing of multiple crushing and fermentation of multi-source organic waste by setting up a discharger 7, and correspondingly setting up a coarse crusher 2, a mixer 3, a feeding screw conveyor 4, and a fine crusher 5 in conjunction with a collection bin 6. It also performs further crushing and fermentation during the fermentation stage. Through a more integrated multi-source organic waste synergistic processing system, it promotes the synergistic mixing, crushing, fermentation, and composting of multi-source organic waste, meeting the technical requirements for the resource utilization of multi-source organic waste fertilizer. The system has a simple structure, small footprint, convenient operation, and higher work efficiency.

[0044] The coarse crusher 2 can be a twin-shaft shredder; the feeding screw conveyor 4 is a shaftless screw conveyor.

[0045] The fine crusher 5 is a horizontal hammer mill fine crusher. To reduce the feeding height of the coarse crusher 2 and increase the discharge height of the unloader 7, the output end of the feeding screw conveyor 4 is connected and installed at the lower part of the axial feeding side of the horizontal hammer mill fine crusher. This makes the interconnection between the coarse crusher 2, the feeding screw conveyor 4, the horizontal hammer mill fine crusher, and the unloader 7 more compact, improving the stability of the multi-source organic waste co-processing system while optimizing the internal space configuration of the system and reducing its footprint. In a preferred embodiment, in the structure where the output end of the feeding screw conveyor 4 is connected to the bottom of the fine crusher 5, the end face of the discharge port of the feeding screw conveyor 4 is connected to the bottom side of the shell of the fine crusher 5 through a sleeve structure. This sleeve structure effectively ensures the connection between the feeding screw conveyor 4 and the fine crusher 5, and further reduces the spatial dimensions of the multi-source organic waste co-processing system.

[0046] In order to reduce the air pressure in the collection bin 6 and prevent dust leakage during system operation, a pressure relief dust collector cage 11 is installed on the collection bin 6. Multiple pressure relief dust collector cages 11 can be set up and arranged vertically in parallel to facilitate the control of air pressure during the crushing process and timely replacement of pressure relief dust collector cages 11 filled with dust and slag.

[0047] To reduce the dust generated by high-pressure air blowing out multi-source organic waste in the collection bin 6 after crushing, the unloader 7 is a star-shaped airlock unloader. It is used to transport materials through the discharge port of the collection bin 6 under negative pressure and to seal the collection bin 6 to prevent air from being sucked in from the discharge port of the collection bin 6 during pneumatic conveying, thus ensuring that the unloader 7 can discharge materials stably and quickly.

[0048] Example 2:

[0049] Please refer to Figures 1 to 12. The multi-source organic waste co-treatment system of Embodiment 2 of the present invention is similar to that of Embodiment 1, except that:

[0050] The coarse crusher 2 is a twin-shaft shredder, with a transmission gear 21 between the twin shafts. This transmission gear 21 is a helical gear. Multiple sets of these helical gears can be arranged in parallel, each set equipped with shredding blades. A shredding blade spacer sleeve 22 is provided on the outer side of each shredding blade. The outer circumference of the spacer sleeve 22 has cutting grooves 221 equal in number to the blade teeth. The blade tips of the shredding blades are fitted to and opposite the cutting grooves 221. When crushing multi-source organic waste, the interaction between the shredding blade spacer sleeve 22 and the cutting grooves 221 rapidly crushes the multi-source organic waste near the shredding blades, allowing it to fall through the cutting grooves 221 into the mixer 3 for thorough mixing, and then into the fine crusher 5 under the action of the feeding screw conveyor 4. The helical gears are particularly effective at cutting bark and small branches, enabling finer crushing of garden waste or kitchen organic waste. This invention significantly improves the efficiency of co-crushing multi-source organic waste by using a helical gear to drive the shredding blade spacer sleeve 22 on the shredding blades in conjunction with the cutting groove 221. The helical gear design also allows for the rapid discharge of the crushed multi-source organic waste, efficiently completing the co-crushing treatment of multi-source organic waste. The fine crusher 5 is a horizontal blade-type fine crusher; the output end of the feeding screw conveyor 4 is connected and installed at the lower part of the axial feed side of the horizontal blade-type fine crusher. This arrangement allows the material in the fine crusher 5 to begin crushing at the bottom. By setting the blade-type fine crusher to a horizontal position, it can fully crush the multi-source organic waste into a pulverized state through the blades and compression action during crushing. The air pressure from the feeding screw conveyor 4 allows the pulverized multi-source organic waste to be quickly and efficiently transferred from the lower part of the horizontal blade-type fine crusher to the upper collection bin 6, further reducing the structural space of the multi-source organic waste co-processing system.

[0051] To further reduce the workload of manual operation of the equipment, the waste elevator 8 is installed. The waste elevator 8 can be set vertically and connected to the frame 1 on the side of the coarse crusher 2. When the equipment is working, multi-source organic waste can be lifted by the waste elevator 8 and poured into the coarse crusher 2 for crushing.

[0052] To further facilitate the weighing of multi-source organic waste processed by the metering equipment, a lifting weighing sensor 9 is connected and installed between the waste elevator 8 and the frame 1. The lifting weighing sensor 9 enables the waste elevator 8 to weigh and measure the multi-source organic waste lifted and fed into the coarse crusher 2 each time. The combined use of the lifting weighing sensor 9 and the waste elevator 8 can maximize the improvement of the ratio of multi-source organic waste material initially added to the coarse crusher 2 and the fermented dry material initially added to the coarse crusher 2, ensuring that the ratio of multi-source organic waste material added to the coarse crusher 2 is within the normal range.

[0053] Example 3:

[0054] Please refer to Figures 1 and 12. The multi-source organic waste co-treatment system of Embodiment 3 of the present invention is similar to that of Embodiment 2, except that:

[0055] In order to reduce the air pressure in the collection bin 6 and prevent dust from leaking out when the equipment is working, an air return pipe 10 is provided between the collection bin 6 and the fine crusher 5. The air return pipe 10 is connected and installed between the collection bin 6 and the fine crusher 5.

[0056] To enable automatic metering of the processed multi-source organic waste, a discharge weighing device 12 is installed. This device can be mounted on the frame 1 beside the unloader 7, or connected to the frame 1 below the unloader 7. The crushed multi-source organic waste is unloaded by the unloader 7 into the container on the discharge weighing device 12 and simultaneously weighed. The weight data from this simultaneous weighing is transmitted in real-time to the system controller, which then controls the operation of the coarse crusher 2, fine crusher 5, collection bin 6, and unloader 7 based on the weight data.

[0057] Example 4:

[0058] Please refer to Figures 1 to 12. The multi-source organic waste co-treatment system of Embodiment 4 of the present invention is similar to that of Embodiment 3, except that:

[0059] To facilitate the receiving, weighing, composting, fermentation, and storage of crushed multi-source organic waste, compost bags 13 are also provided. During the crushing operation, the compost bags 13 are placed below the unloader 7 and above the discharge weighing device 12 to receive the crushed multi-source organic waste. Once the bag is full of crushed multi-source organic waste, it can be transported, fermented, and stored through the compost bags 13. The compost bags 13 are made of plastic woven bag sheets or non-woven fabric. For easy handling, a handle 131 is symmetrically sewn on each of the left and right sides of the compost bag 13.

[0060] Example 5:

[0061] Please refer to Figures 1 to 12. The multi-source organic waste co-treatment system of Embodiment 4 of the present invention is similar to Embodiment 4, except that:

[0062] In order to improve the crushing and feeding efficiency of multi-source organic waste, including garden greening waste, and to prevent large branches and bamboo strips from swinging and injuring operators when being torn apart, a material support mechanism 14 is also installed. The material support mechanism 14 is connected and installed above the feeding hopper of the coarse crusher 2 and is arranged along the edge of the feeding hopper of the coarse crusher 2. It is used to block the swinging and ejection of multi-source organic waste in the coarse crusher 2 during crushing.

[0063] To facilitate the organized treatment and emission of fermentation waste gas during the composting and fermentation of multi-source organic waste, a composting fermentation chamber 15 is added. The composting fermentation chamber 15 is located next to the frame 1 and can generally be installed on the ground of the treatment site. The composting bags 13 are filled with mixed and crushed multi-source organic waste and piled in the chamber for composting and fermentation. The composting fermentation chamber 15 is also equipped with a gas collector and deodorization and purification equipment, which are used to collect the fermentation waste gas generated in the composting fermentation chamber 15 in a centralized manner through the gas collector and treat it through the deodorization and purification equipment before it is safely, harmlessly and orderly discharged, making the treatment of multi-source organic waste safer, more environmentally friendly and standardized.

[0064] The above are merely preferred embodiments of this application and are not intended to limit this application in any way. Although this application has disclosed preferred embodiments as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application.
