How to deal with domestic waste efficiently and environmentally friendly has become a major environmental problem and social challenge facing the world. At present, the mainstream methods of domestic waste treatment include landfill, incineration, composting, etc., but these methods have significant defects. Since about 50%-70% of domestic waste is degradable organic matter (such as kitchen waste contains a large amount of carbohydrates and proteins), microorganisms can convert it into high-value products, realizing the transformation from "waste" to "usable biological resources."

[0003] A Chinese patent with publication number "CN112337946A" discloses an organic waste microbial treatment device, including a feeding hopper, a waste crushing mechanism, a cleaning mechanism, a solid-liquid separation and conveying mechanism, and a solid waste microbial decomposition mechanism. The waste crushing mechanism includes a crushing chamber, a crushing knife shaft, a crushing knife, a screen, and a first motor; the solid waste microbial decomposition mechanism includes a microbial reaction chamber, an agitator, and a fourth motor. The device is used for microbial decomposition of organic waste, and at the same time, crushes and refines, desalinates, and separates solids and liquids before microbial decomposition, which can improve decomposition efficiency and ensure long-term use and efficient operation.

[0004] During its later use, the device still had the following problems: it lacked a screening mechanism for domestic waste and was unable to separate different types of waste, affecting the efficient treatment of organic matter in domestic waste. Summary of the Invention

[0013] Preferably, a treatment method using a treatment device for degrading domestic waste by microorganisms comprises the following steps: a: First, the domestic waste is put into the crushing mechanism for crushing. After crushing, it moves to the bottom of the magnetic separator along with the conveying mechanism for magnetic separation to remove the metal waste in the domestic waste; b: The remaining domestic waste enters the air separation bin, and the air pump is started. The light waste is discharged from the light waste outlet under the blowing of the air flow. The fiber and plastic waste is blocked by the fixed bracket and is discharged from the fiber and plastic waste outlet under the push of the rotating push rod. The remaining domestic waste enters the transfer bin through the feed port 1 and the feed port 2, and enters the heavy material separation bin from the feed port 3 under the push of the pushing mechanism; c: The heavy material separation bin is filled with water. When domestic garbage enters the heavy material separation bin, materials with higher density such as glass and stone will settle to the bottom, enter the outer cavity from the notch at the bottom of the inner filter cartridge, and move to the heavy material outlet under the push of the outward propeller. They can be discharged by opening the valve; d: As for other domestic garbage, due to its low density, it is difficult to settle to the bottom of the water under the buoyancy of water. It moves to the pushing and rotating propeller area under the push of the inner propeller, and enters the crushing and slurrying bin from the feed port 4; e: Due to the compaction of the compacting blocks, some softer organic matter passes through the filter ring and is further crushed and flows into the anaerobic fermentation tank in liquid form.

The solid domestic waste such as coarse fibers and debris that cannot pass through the filter ring enters the aerobic composting bin from the solid phase outlet under the push of the scraper and is produced as organic fertilizer.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up an air separation bin, a heavy material separation bin and a rolling pulping bin, it is possible to separate light waste such as plastics and products, heavy waste such as stone and glass, and rope plastic fiber waste from domestic waste, thereby improving the efficiency of using microorganisms to degrade organic matter; 2. By setting up a compaction slurry bin, the crude fibers and hard materials in the domestic waste that require a long time for microorganisms to degrade are separated; the domestic waste that is difficult to degrade quickly is aerobically composted to produce organic fertilizer, and the organic matter that has been slurried is anaerobically fermented to produce biogas, maximizing the utilization of various types of waste resources and avoiding waste; 3. By setting up a rolling and slurrying mechanism, under the push of compression spring 1, the rolling block remains away from the filter ring, and the scraper remains in contact with the filter ring to scrape the filter ring. When the rolling block contacts the extrusion rail, the rolling block continues to approach the filter ring to crush the material. At the same time, compression spring 1 reversely squeezes the scraper, and the scraper increases the scraping force on the filter ring, cooperating with the rolling block to complete the crushing operation of the organic matter. 4. By setting up an air separation mechanism, when the pressing block contacts the fixed card frame, the sliding card block extends outward, and the outer side of the sliding card block is fixedly connected with a card tooth, which can increase the friction with the fiber plastic waste and prevent the fiber plastic waste from sliding off at will when cleaning the fiber plastic waste.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings: The directional terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation shown in the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings within the present invention based on the specific circumstances.

[0018] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, a device for processing domestic waste by microbial degradation comprises a crushing mechanism 1, a conveying mechanism 2 is fixedly installed at the bottom of the crushing mechanism 1, and a magnetic separator 3 is fixedly installed in the middle of the conveying mechanism 2. The domestic waste is first crushed into small pieces by the crushing mechanism 1 to facilitate the subsequent sorting of different types of waste; the magnetic separator 3 is provided to select and separate metal impurities in the domestic waste; a wind separation bin 4 is fixedly provided at the rear end of the conveying mechanism 2, and a wind separation mechanism 11 is provided inside the wind separation bin 4. By providing the wind separation bin 4, the heavy material separation bin 6 and the rolling pulping bin 7, the domestic waste is effectively sorted. The present invention is to separate light garbage such as plastics and products, heavy garbage such as stone and glass, rope and plastic fiber garbage and other materials in domestic garbage, and improve the efficiency of using microorganisms to degrade organic matter; a driving motor 2 10 is fixedly installed on the right outer wall of the air separation chamber, and the driving motor 2 10 is started. Under the drive of the driving motor 2 10, the air separation mechanism 11, the pushing mechanism 12, the heavy material separation mechanism 13 and the rolling pulping mechanism 14 are put into operation to sort the light garbage, plastic fiber, heavy garbage, and the harder and softer materials in the organic matter.

[0019] The left side of the winnowing bin 4 is fixedly connected with a transition bin 5, such as Figure 14 As shown, a second feeding port 501 is fixedly provided on the right side wall at the bottom of the transition bin 5, and a third feeding port 502 is fixedly provided on the left side wall at the top of the transition bin 5. A pushing mechanism 12 is provided inside the transition bin 5. After the domestic waste enters the transition bin 5 from the bottom, it moves upward to the feeding port 502 under the push of the pushing mechanism 12 and enters the heavy material separation bin 6. Since water is stored in the heavy material separation bin 6 to separate the heavy material waste through buoyancy, the provision of the transition bin 5 prevents water from flowing into the air separation bin 4 and affecting the air separation operation of the domestic waste. The heavy material separation bin 6 is fixedly connected to the left side of the transition bin 5, and a heavy material separation mechanism 13 is fixedly provided inside the heavy material separation bin 6.

[0020] The heavy material separation bin 6 is filled with water, and the water is added to half the height of the heavy material separation bin 6. The domestic garbage is stratified under the buoyancy of the water. The domestic garbage with higher density and weight, such as sand, stone, glass, etc., enters the outer cavity 1 604 through the gap and accumulates to the heavy material outlet 602 under the push of the outward propeller 1304. Finally, the valve 15 is opened to discharge it, completing the separation of the heavy garbage. The remaining domestic garbage is difficult to settle at the bottom of the heavy material separation bin 6 under the influence of water. It is moved to the left side of the heavy material separation bin 6 under the push of the inner propeller 1305, and is separated from the water body under the drive of the pushing propeller 1303, and enters the rolling slurry bin 7 through the material outlet 4 601; the rolling slurry bin 7 is fixedly connected to the left side of the heavy material separation bin 6, and a rolling slurry mechanism 14 is provided inside the rolling slurry bin 7.

[0021] By setting up a rolling pulping bin 7, the crude fibers and hard texture of domestic waste that require a long time for microorganisms to degrade can be separated; the domestic waste that is difficult to degrade quickly can be aerobically composted to produce organic fertilizer, and the organic matter that has been pulped can be anaerobically fermented to produce biogas, thereby maximizing the utilization of various types of waste resources and avoiding waste. By providing a rolling and slurrying mechanism 14, and under the push of a compression spring 1404, the rolling block 1402 is kept away from the filter ring 703 so that the material can enter between the rolling block 1402 and the filter ring 703. The scraper 1403 maintains contact with the filter ring 703, scraping the filter ring 703 to prevent the material from moving backward out of the area of ​​the rolling block 1402 and reducing the rolling efficiency. When the rolling block 1402 contacts the extrusion rail 705, the rolling block 1402 continues to approach the filter ring 703 to roll the material. At the same time, the compression spring 1404 is compressed, and the scraper 1403 increases the scraping force on the filter ring 703, thereby increasing the blockage of the material and preventing it from escaping from the rolling block 1402. An aerobic composting bin 9 is fixed to the rear of the rolling and slurrying bin 7.

[0022] like Figure 22 As shown, aerobic composting bin 9 includes bin body 901, with a discharge pipe 901A fixedly connected to the bottom sidewall of bin body 901. A valve plate 901B is slidably mounted on discharge pipe 901A. Drive motor 1 902 is fixedly mounted on the other sidewall of bin body 901, and a stirring paddle 903 is fixedly connected to the output shaft of drive motor 1 902. By providing aerobic composting bin 9 for aerobic composting of solid-phase materials, and cooperating with stirring paddle 903 to stir the materials, an adequate supply of oxygen is ensured, and after processing, organic fertilizer is generated, achieving full utilization of resources.

[0023] like Figure 7 、 Figure 8 and Figure 13 As shown, a feed port 401 is fixedly provided on the outer wall of the front end of the air separation bin 4, a blowing chamber 402 is fixedly provided at the bottom of the feed port 401, a suction chamber 404 is fixedly provided on the top of the air separation bin 4, and a spoiler is fixedly provided in the suction chamber 404, so that the air flow can be relatively dispersed and slowly sucked into the ventilation pipe from the suction chamber 404, while preventing the garbage from being directly entrained by the air flow into the ventilation pipe; Figure 3 and Figure 4As shown, the suction chamber 404 is connected with the blowing chamber 402 through the ventilation pipe 403, and an air pump 403A is fixedly installed on the ventilation pipe. Driven by the air pump 403A, the air flow can be blown out from the blowing chamber 402 and sucked back from the suction chamber 404, so as to perform air separation on the light garbage in the domestic garbage and separate the light garbage; a light garbage outlet 405 is fixedly provided on the outer wall at the rear end of the air separation bin 4, and a fixed baffle 409 extends inwardly from the light garbage outlet 405, and a fiber plastic garbage outlet 406 is fixedly provided at the bottom of the air separation bin 4, and the fiber plastic garbage outlet 406 opens to the right, and a feed port 1 407 is fixed at the front of the fiber plastic garbage outlet 406, and the feed port 1 407 is in contact with the feed port 2 501, and the opening of the feed port 1 407 faces to the left.

[0024] Both the feed port 407 and the fiber plastic garbage outlet 406 are equipped with inclined plates, so that the garbage can slide out under the action of gravity, avoiding garbage accumulation here and affecting the subsequent air separation work; a fixed bracket 408 is fixedly connected above the feed port 407, and the fixed bracket 408 can block the falling domestic garbage. Most of the garbage processed by the crushing mechanism 1 can fall smoothly into the feed port 407, but for fiber plastic garbage such as ropes, the crushing mechanism 1 cannot crush them completely. If such garbage enters the subsequent processing flow, it will seriously affect the progress of other garbage separation operations. Therefore, it is blocked by the fixed bracket 408 and pushed by the rotating push rod 1103 to separate such garbage and fall into the fiber plastic garbage outlet 406.

[0025] like Figure 9 、 Figure 10 、 Figure 11 and Figure 12As shown, the air separation mechanism 11 includes a rotating wheel 1101, which is rotatably connected to the air separation chamber 4, and the right end of the rotating wheel 1101 is fixedly connected to the output shaft of the driving motor 2 10. The rotating wheel 1101 rotates under the drive of the driving motor 2 10. As the rotating wheel 1101 rotates, the rotating push rod 1103 is initially restricted by the fixed block cover 409 and retracts into the installation slot 1101A. When the rotating push rod 1103 rotates to the front and disengages from the fixed block cover 409, the rotating push rod 1103 extends outward from the installation slot 1101A under the push of the large compression spring 1102. As the rotating push rod 1103 continues to rotate, the rotating push rod 1103 begins to contact the fixed bracket 408. Due to the small pressure The elastic coefficient of spring 1106 is much smaller than the elastic coefficient of large compression spring 1102. First, the small compression spring 1106 is compressed, the pressure block 1104 moves inward, and pushes the sliding block 1105 outward, restricting the contact of the fiber plastic waste, and pushing the fiber plastic waste backward into the fiber plastic waste outlet 406. Without the squeezing of the fixed card frame 408, the small compression spring 1106 drives the pressure block 1104 to return to its original position, and the pressure block 1104 drives the sliding block 1105 to retract into the sliding cavity 1103B, ensuring that the fiber plastic waste slides off the rotating push rod 1103. As the wheel 1101 continues to rotate, the rotating push rod 1103 is abutted by the fixed block cover 409 and retracts into the mounting slot 1101A.

[0026] The left end of the rotating wheel 1101 is fixedly connected with the pushing mechanism 12, a plurality of installation grooves 1101A are fixedly arranged on the outer wall of the rotating wheel 1101, the outer wall of the rotating wheel 1101 is in rotational contact with the fixed baffle 409, a large compression spring 1102 is fixedly connected at the bottom of the installation groove 1101A, one end of the large compression spring 1102 is fixedly connected with a rotating push rod 1103, the rotating push rod 1103 is in sliding connection with the installation groove 1101A, a hole groove one 1103A is fixedly arranged at the top center of the rotating push rod 1103, a small compression spring 1106 is fixedly connected at the bottom of the hole groove one 1103A, a pressing block is fixedly connected at the other end of the small compression spring 1106, the width of the pressing block 1104 is slightly larger than the width of the blocking rod frame on the fixed clamping frame 408, with the rotation of the rotating push rod 1103, the pressing block 1104 contacts the fixed clamping frame 408 and compresses the small compression spring 1106 inward, drives the sliding clamping block 1105 to extend outward from the sliding cavity 1103B, contacts and limits the fiber plastic garbage, avoids the fiber plastic garbage from accidentally falling off the fixed clamping frame 408 when being pushed backward; the pressing block 1104 has extrusion blocks 1104A extending outward on both sides, the pressing block 1104 is in sliding connection with the hole groove one 1103A, sliding cavities 1103B are fixedly arranged at the upper part of both sides of the hole groove one 1103A, sliding clamping blocks 1105 are in sliding connection in the sliding cavities 1103B, the sliding clamping blocks 1105 are fixedly connected with clamping teeth on the outer side, which can increase the friction with the fiber plastic garbage and avoid the fiber plastic garbage from accidentally falling off when cleaning; the sliding clamping blocks 1105 are in sliding connection with the extrusion blocks 1104A on the back, hole grooves two 1103C are fixedly arranged at the bottom of the rotating push rod 1103, and the hole grooves two 1103C are connected with the large compression spring 1102 at the bottom.

[0028] As Figure 15 and Figure 16As shown, the heavy material separation mechanism 13 includes a rotating frame 1301, the right end of the rotating frame 1301 is fixedly connected to the pushing mechanism 12, and the outer side of the left side of the rotating frame 1301 is fixedly connected to an outward pushing propeller 1304, which cooperates with the outer cavity 1604; the inner side of the left side of the rotating frame 1301 is fixedly connected to an inner pushing propeller 1305, and the pitch of the outward pushing propeller 1304 is much smaller than the pitch of the inner pushing propeller 1305. Therefore, as the rotating frame 1301 rotates, the inner pushing propeller 1305 can push the garbage material forward a farther distance. Due to the speed difference, it will produce a stirring effect on the water in the heavy material separation bin 6, which is convenient for separating heavy garbage from other domestic garbage; a filter hole is fixedly provided on the inner pushing propeller 1305; by setting the filter The holes and the inner filter cylinder reduce the impact on the water in the bin when the domestic garbage wants to be pushed to the left, allowing the water to flow to the right again through the filter holes, reducing the resistance to the rotation of the rotating frame 1301 and avoiding the waste of power of the driving motor 2 10; the center of the left side of the rotating frame 1301 is fixedly connected with a transmission cylinder 1302, and the transmission cylinder 1302 cooperates with the inner push propeller 1305. The transmission cylinder 1302 fills the area in the center of the inner push propeller 1305 to ensure that the domestic garbage can continue to contact the inner push propeller 1305 and be pushed to the left by the inner push propeller 1305; the left side of the transmission cylinder 1302 is fixedly connected with a pushing paddle 1303, which pushes the domestic garbage upward and enters the compacting slurry bin 7 from the feeding port 3 502.

[0029] like Figure 17 As shown, a solid phase outlet 701 is fixedly provided on the rear outer wall of the rolling pulping bin 7, a liquid phase outlet 702 is fixedly connected to the bottom outer wall of the rolling pulping bin 7, and an anaerobic fermentation tank 8 is fixedly connected to the bottom of the liquid phase outlet 702.

Extrusion rails 705 are fixedly connected to the inner walls of both sides of the rolling pulping bin 7. Softer organic matter is crushed and passes through the filter ring 703, while harder organic matter such as coarse fiber is scraped backward by the scraper 1403 and discharged from the solid phase outlet 701.

[0030] like Figure 18 、 Figure 19 、 Figure 20 and Figure 21As shown, the rolling pulping mechanism 14 includes a rotating frame 1401, a slide groove 1401A is provided on the side wall of the rotating frame 1401, a rolling block 1402 is slidably connected to the inside of the rotating frame 1401, and a slot 1402B is fixedly provided on the rear of the rolling block 1402. There are protrusions 1402A extending outward on both sides of the rolling block 1402, and the protrusions 1402A slide with the slide groove 1401A. The protrusions 1402A cooperate with the extrusion rail 705. When the protrusions 1402A move to the bottom with the rotating frame 1401, the extrusion rail 705 squeezes the protrusions 1402A downward, driving the rolling block 1402 to continuously move toward the filter ring 703, and the organic matter at the bottom of the rolling block 1402 is rolled and pulped. There are multiple groups of friction strips fixedly connected to the bottom surface. By setting the friction strips, the friction force of the crushing block 1402 on the organic matter is increased, the crushing efficiency of the crushing block 1402 is improved, and the organic matter is prevented from sliding forward when being crushed and cannot be fully crushed; a scraper 1403 is slidably connected to the rear side wall of the crushing block 1402, and the scraper 1403 scrapes the filter ring 703 to prevent the organic matter from adhering to the filter ring 703, and continuously scrapes the solid-phase organic matter backward; the scraper 1403 is slidably connected to the rotating frame 1401, and a convex plate 1403A extends outward from the front of the scraper 1403, and a compression spring 1404 is fixedly connected to the top of the scraper 1403, and the other end of the compression spring 1404 is fixedly connected to the slot 1402B.

[0031] Pushed by the compression spring 1404, the crushing block 1402 moves upward away from the surface of the filter ring 703, leaving a gap with the filter ring 703. As the rotating frame 1401 continues to rotate, the gap is filled with domestic waste that needs to be processed, and the crushing block 1402 gradually approaches the filter ring 703 under the extrusion of the extrusion rail 705, crushing the domestic waste in the gap. The softer material passes through the pores of the filter ring 703 into the outer cavity 2 704, and enters the anaerobic fermentation tank 8 through the liquid phase outlet 702. The anaerobic fermentation tank 8 is a prior art, with a sealed space inside and various feed pipes, a discharge pipe 901A and a variety of valves 15 to control the smooth progress of the entire fermentation process, and various treatments are performed on the liquid phase waste according to fermentation requirements.

[0032] A method for treating domestic waste using a microbial degradation device comprises the following steps: a: First, the domestic waste is put into the crushing mechanism 1 for crushing. After crushing, it moves to the bottom of the magnetic separator 3 along the conveying mechanism 2 for magnetic separation to remove metal waste from the domestic waste; b: The remaining domestic waste enters the air separation bin 4, and the air pump 403A is started. The light waste is blown out from the light waste outlet 405 by the air flow. The fibrous plastic waste is blocked by the fixed bracket 408 and is pushed out from the fibrous plastic waste outlet 406 by the rotating push rod 1103. The remaining domestic waste enters the transfer bin 5 through the feed port 1 407 and the feed port 2 501, and enters the heavy material separation bin 6 through the feed port 3 502 under the push of the pushing mechanism 12; c: When household garbage enters the heavy material separation bin 6 filled with water, materials with higher density, such as glass and stones, will settle to the bottom, enter the outer chamber 1 604 through the notch at the bottom of the inner filter cartridge 603, and move to the heavy material outlet 602 under the push of the propeller 1304. The waste can be discharged by opening the valve 15. d: Other domestic waste has a low density and is difficult to settle to the bottom of the water due to the buoyancy of the water. It is pushed by the inner propeller 1305 to move to the area of ​​the pusher paddle 1303 and enter the crushing and slurrying bin 7 through the feed port 601; e: Due to the compaction by the compacting block 1402, some softer organic matter passes through the filter ring 703, is further crushed, and flows into the anaerobic fermentation tank in liquid form. This part of domestic waste has a high organic matter content and produces biogas through anaerobic fermentation. The solid domestic waste such as crude fibers and debris that cannot pass through the filter ring 703 enters the aerobic composting bin 9 from the solid phase outlet 701 under the push of the scraper 1403 and is produced as organic fertilizer.

[0033] The present invention realizes the separation of light garbage such as plastics and products, heavy garbage such as stone and glass, and rope-type plastic fiber garbage in domestic garbage by setting an air separation bin 4, a heavy material separation bin 6 and a rolling pulping bin 7, thereby improving the efficiency of using microorganisms to degrade organic matter; by setting the rolling pulping bin 7, domestic garbage such as coarse fiber and hard texture that require microorganisms to consume a long time to degrade is separated; domestic garbage that is difficult to degrade quickly is aerobically composted to produce organic fertilizer, and the organic matter that has been pulped is anaerobically fermented to produce biogas, thereby maximizing the utilization of various types of garbage resources and avoiding waste; by setting an air separation mechanism 11, when the pressing block 1104 contacts the fixed bracket 408, the sliding block 1105 extends outward, and the sliding block 1105 is fixedly connected to the outside with a tooth, which can increase the friction with the fiber plastic garbage, and avoid the fiber plastic garbage from sliding off at will when cleaning the fiber plastic garbage.
